Additionally called as essential epidermoid carcinoma of bone, dangerous angioblastoma or epithelial tumor of bone. It was first portrayed by Fischer in 1913.1 It speaks to under 0.4% of all harmful bone tumors.2 The specific birthplace of adamantinoma is obscure, the exemplary variation is made out of epithelial cells and osteofibrous segments. It is more pervasive in men than in ladies, proportion being 5:4. The basic time of introduction is in the subsequent decade, however it can change enormously between the second to fifth decades.3 The regular site of event is the ramus of the mandible. The other extraordinary areas incorporate shaft of long bones (97%), mid-shaft of tibia (80%-85%).4 Other uncommon areas incorporates the humerus, ulna, femur, fibula and range however ribs, spine, metatarsal and carpal bones.5 The trademark highlights of adamantinoma is moderate, continuous advancement with high odds of nearby repeats and furthermore metastases to lungs.6 For this situation study, we have introduced an uncommon histological acanthomatous variation of adamantinoma of the correct tibia with metastases to the privilege inguinal district. CASE REPORT: A multi year old male patient gave history of torment in right leg since 3-4 months, tricky beginning, bit by bit dynamic, bothered on work out, soothed on rest and drug. Later patient had no alleviation taking drugs. There was no history of injury or fall preceeding to beginning of side effects. The patient additionally whined of growing in the correct crotch since multi month, without torment. On assessment, the patient was steady. Neighborhood assessment appeared, an expanding of about 5X3cm in the upper end right leg, delicate, all around characterized, hard in consistency, smooth surface, including the correct knee joint line. There was limitation of development, however scope of developments was available. Assessment of right inguinal locale uncovered a 7X6cm firm, non-tangled mass, fixed, non-delicate, non-reducible, non-pulsatile mass. Nearby assessment of penis, scrotum, butt-centric channel, hernia openings was typical. Pattern examinations were done, all the hematological parameters were ordinary, ultrasound midsection and chest radiograph was typical. Plain radiograph of right tibia indicated huge focal lytic injury with sclerotic edges, including the upper end and shaft of tibia without inclusion of right knee joint. Supra-patellar removal of right leg with right inguinal and right outer iliac nodal analyzation was finished. Histopathological assessment of the mass was finished. The revealed was reminiscent of acanthomatous adamantionoma. The highlights are as depicted, focal zone of squamous cell homes which were very much separated with keratinization encompassed by an edge of myxoid cells. Further immunohistochemistry(IHC) study was done to affirm the analysis. IHC was likewise predictable with the determination and affirmed the finding. Energy was found for cytokeratin(CK), EMA, CK-19, CK-5, CK-6, P-63, and Ki-67 and vimentin. Additionally metastases to right inguinal lymph hub was affirmed. Conversation: The primary bone tumor with epithelial trademark was accounted for by Maier in 1900, later in 1913 Fischer named it as adamantinoma. It is more typical in men than in ladies. The period of introduction shifts between the second to fifth decade. The extraordinary destinations incorporates the pole of long bones(97%), of which the mid-shaft of tibia being the most well-known site(80-85%). The side effects at introduction incorporate agony with restricted expanding. Growing is the most widely recognized indication. Torment might be available because of history of redundant injury related with adamantinoma.7 Adamantinoma is poor quality harmful tumor, and can metastasize to loco-territorial nodal zones and to lungs at introduction. The patient for the situation report was likewise a moderately aged man in the fifth decade with torment and expanding in the correct tibia since 3-4 months and growing in the correct crotch. Three hypotheses have been proposed for the wellspring of cell of source, 1) epithelial, 2) angioblasts, and 3) synovial tumors from extraordinary ectopic destinations. This was done on the grounds that the tumor tissue is made out of both epithelial and osteofibrous components.8 In various mixes, various examples are framed. On microscopy, the commonest structure is the old style variation, trailed by the osteofibrous design. In the exemplary variation, the sorts are basaloid, axle cell, cylindrical, and squamous designs. In the traditional variation, focal epithelial part with encompassing zone of stringy tissue containing hardly any youthful trabecuated bone segments are seen. In the osteofibrous variation, cental zone of stringy tissue, encompassed by fringe zone of epithelial segments are seen. Axle cell variation is most normally observed with repetitive sore and metastatic injuries. The regular discoveries of old style variation were predictable for our situation also, which d emonstrated a very much separated keratinizing example of squamous cell homes encompassed by an edge of myxoid cells. Immunohistochemistry shows energy for both epithelial and rigid components. Sinewy segments are sure for vimentin. Epithelial parts show energy for cytokeratin(CK) 5, 14, 19; infrequently positive for CK 1,13,17. It is generally negative for CK 8 and 18. Likewise shows inspiration for epithelial development factor, fibroblast development factor, fibroblast development factor receptor. Our case had includes as depicted, likewise energy was found for p-63, Ki-67 and CK-6, which favor our determination of acantomatous adamantinoma. Hereditary examinations uncover chromosomal abberations on chr 7,8,12,19.9 Also aneuploidy has been related with epithelial components.10 There is loss of heterozygosity of p53 quality. Rarely,(11;22) translocations have been accounted for in the event of adamantinoma, and is named adamantinoma-like ewingââ¬â¢s sarcoma.11 11;22 translocation isn't seen is in adamantinoma. Radiological examinations incorporate radiographs, PC tomography(CT), attractive resonace imaging(MRI). All the modalities are essential not exclusively to affirm the determination, likewise to characterize the degree of include and the forcefulness of the tumor. On plain radiographs normally unpredictable, lobulated, cental lytic injuries with a fringe sclerosis is available in the diaphyseal or metaphyseal parts of the bargains. These injury will in general show up on tibia with a run of the mill image of cleanser bubble appearance.12 CT shows osteolytic sore in the bone. X-ray is the examination of decision. It helps not just in characterizing the degree of cortical association of bone, delicate tissue contribution, yet additionally helps in precluding different etiologies, for example, ewingââ¬â¢s sarcoma, adamantinoma, osteosarcoma, metastatic sickness, sinewy dysplasia of bone.13 The regular highlights as portrayed in the writing was valid for our situation too. Treatment of adamantinoma has no conclusive rules. Excisional biopsy is favored as opposed to curratage of bone. Curratage of bone is related with recurrenceââ¬â¢s, upto 30% repeat has been accounted for with curettage.14 Radical extraction of the bone is related with better result and anticipation. Appendage rescue methods incorporate en-square resection, trailed by recreation of the hard deformity which incorporates vascularised or non-vascularised bone unions, specially crafted protheses, intercalary allografts and interruption osteogenesis.15 When appendage rescue is absurd, removal is the authoritative treatment of decision. The rate of mortality with adamantinoma is about 17%, and increments to about 20% when aspiratory metastasis is available. In our patient work up was done and right supra patellar removal was done, with right inguinal and right outer iliac lymph nodal analyzation was done and histopathological assessment further demonstrated metastases to right inguinal a rea.

So as to introduce a solid end, we need to get into a significant conversation to contrast upsides and downsides of totally serious market and furthermore talk about the change it has with imposing business model structure. Impeccable Competition and Efficiency: According to Adam Smith totally serious market works under ââ¬Å"invisible handâ⬠in which every person in the public arena searches out for the individual premium. Be that as it may, so as to lecture it, he/she needs to exchange off his effects with the person who is eager to get profited by it. This eventually prompts advantage of society purposefully or unexpectedly. Hypothetically; there are numerous purchasers and dealers, indistinguishable items, no hindrances to section just as leave (Thomas E. Woods, 2011). Purchasers and venders both have the ideal data and thus they are the ââ¬Å"price takersâ⬠wh ich brings about an entirely versatile interest bend. This implies if a firm needs to augment its benefit it should sell its item at advertise cost. This implies proficiency is required to hold the expense down and increment the net overall revenue. Productivity is acknowledged whenever all chances to improve somebody off without exacerbating anybody off are depleted. It is additionally called ââ¬ËPareto Efficiencyââ¬â¢ in the vast majority of the worldwide originations (Books Llc, 2010). Under perfect conditions in a completely serious market or whatever other market which is working great, the market harmony boosts the contrast between the advantages society gets from the great and administrations and what it costs society to create. A totally serious market would consistently concentrate on the most extreme net social advantage. Advantage isn't just considered by the fiscal return accomplished from ventures yet in addition the certain increase acknowledged by the general pu blic all in all. A proficient allocation of assets is cultivated if increase in societyââ¬â¢s by and large degree of fulfillment by a greater amount of one great and less of another great is beyond the realm of imagination. This is the reason rivalry is favored as it for the most part prompts positive results. Rivalry urges players to perform better than their opponent which at last prompts better market system. Such productivity is acknowledged by elements if the cost of a decent is equivalent to the negligible expense of the item. An elaboration of the above system is as per the following: We know from the above conversation that market gracefully shows the negligible expense of society of delivering the great or administration. Additionally, the interest bend is the minimal advantage to society from devouring the great or administration. In this manner, the net social advantage would be augmented if the negligible social expense is equivalent to the peripheral social advantage (Tucker, 2010). Considering the expense designated to society, the market gracefully is the even entirety of each firmââ¬â¢s MC bend or at the end of the day it shows what it expenses to create one extra unit of good. Financial specialist says that on the off chance that all the expenses are processed by the organizations, at that point gracefully rises to the minor social cost (Lambert M. Surhone, 2010). Then again, economistsââ¬â¢ measure benefits as far as the ability of buyers to pay in this way, the market request would be a portrayal of the complete whole of readiness to pay for a unit of good at each degree of utilization. The market request component centers around expansion of social advantage showed beneath: All shoppers whose WTP (eagerness to pay) surpasses P will purchase a decent (or more Violeta Mccarterhttp://www.blogger.com/profile/02705446514355823397noreply@blogger.com0tag:blogger.com,1999:blog-1687764708120168264.post-33520893562908104762020-08-21T22:19:00.001-07:002020-08-21T22:19:39.214-07:00Corruption of Power â⬠Macbeth EssayShakespeareââ¬â¢s bleeding and appalling play Macbeth, written in the seventeenth century, depicts dazzle desire, appearances can be deluding and defilement of intensity. It follows the explanations for Macbethââ¬â¢s defeat. The play examines how other outside powers can without much of a stretch change the way of ones wants and choices. The witchesââ¬â¢ interruption, Lady Macbethââ¬â¢s control and Macbethââ¬â¢s dim wants all meddle and control Macbethââ¬â¢s choices. He goes from being adulated as a respectable officer to a double crosser and degenerate lord. In the play, Macbeth perpetrates numerous awful wrongdoings; anyway he is exclusively not liable for every one of them. The outside variables control his choices and are answerable for his defeat toward the end. To start, the witchesââ¬â¢ control Macbeth right off the bat in the play by unequivocally affecting his choices. The witches plan to disclose to Macbeth his destiny after a fight has is lost and won. While making a trip to King Duncanââ¬â¢s palace Macbeth and Banquo discover the three witches. The principal witch welcomes Macbeth with his present title as the Thane of Glamis, the subsequent witch welcomes Macbeth as the Thane of Cawdor, and the last witch welcomes Macbeth as, ââ¬Å"All hail Macbeth that shalt be top dog hereafterâ⬠(1. ii. 53). The welcome are predictions that plant a negative seed of visually impaired aspiration in Macbethââ¬â¢s musings and the expectations are a methodology for the witchesââ¬â¢ benefit to set up trust. Not long after the witchesââ¬â¢ vanish, two Scottish Nobles â⬠Angus and Ross â⬠illuminate Macbeth regarding his new title as the Thane of Cawdor notwithstanding his present title as Thane of Glamis. The news makes Macbeth confident and conjures dazzle aspiration, that he may become lord. The expectation may work out effectively as the Thane of Cawdor title managed without making hurt anybody. When Macbeth really becomes King, the weight and blame of his activities begin to construct. He begins to stress and is uncertain over his seat in light of the fact that the witches additionally anticipate that Banquoââ¬â¢s relatives will become ruler. He chooses to convince two homicides to perpetrate the massive wrongdoing of killing his old buddy. Macbeth expects to kill Banquo and his child Fleance, since they represent an extraordinary danger to his crown. After Macbeth is fruitful in convincing the two killings he arranges the two homicides, ââ¬Å"to leave no rubs nor bungles in the work/Fleance, his child, that stays with him,/Whose nonattendance is no less material to meâ⬠(3. . 153-155). Macbeth shows dread toward the expectation the witches predicted Banquo and this pushes him to kill by and by. Additionally, the forecast was not implied legitimately at Banquo however for his relatives to manage Scotland as future rulers. Macbeth doesn't need this since he wants hi s own descendents to become future lords. Banquo, and his child Fleance are a negligible deterrent that need evacuating and Macbeth shows no worry or regret in his choice to kill his dear friend Banquo and his child. Afterward, Macbeth gets news about Banquoââ¬â¢s demise and Fleanceââ¬â¢s escape is help be that as it may, it is fleeting when Macbeth begins to see the phantom of Banquo. Macbeth is sickened and frightened which drives him to the choice of visiting the three witches for answers. Macbeth is feeling uncertain and fears Fleance returning and removing the seat from him. There in a cavern, the witches call upon their lords, the three specters to answer Macbethââ¬â¢s demand for data. The primary specter, an outfitted head, advises Macbeth to be careful regarding Macduff. The subsequent ghost, a ridiculous kid, encourages Macbeth to be secure and not stress, in light of the fact that any man conceived from a lady can not hurt Macbeth. Macbeth giggles at this apparitionââ¬â¢s forecast on the grounds that each man is conceived from a lady and the second apparitionââ¬â¢s expectation gives him more certainty and self-importance. Finally, the last phantom, a delegated kid with a tree in its grasp, advises Macbeth to be glad and not frightful in light of the fact that he can't be vanquished ââ¬Å"until/Great Birnam Wood to high Dunsinane Hill/Shall come against himâ⬠(4. I. 106-107). Macbeth is pleased to hear this expectation from the third specter since he realizes trees can not move and this data gives Macbeth the certainty he was looking for so as to have a sense of safety about his position and his seat can not be removed. He feels as though nobody can hurt him. In spite of the fact that the spirits are right, the witches have wound reality for Macbeth to feel invulnerable and sure on the choices he is making to cause him hurt sooner rather than later. Also, Lady Macbethââ¬â¢s daze desire and deception participate in further modifying Macbethââ¬â¢s choices. Woman Macbeth peruses Macbethââ¬â¢s letter and she quickly begins to plot King Duncanââ¬â¢s murder so the witchesââ¬â¢ predictions can her spouses wants can turn out to be valid. She realizes Macbeth is, ââ¬Å"too full oââ¬â¢ thââ¬â¢ milk of human benevolence/â⬠¦ That wouldst thou holily; wouldst not play bogus/And yet wouldst wrongly winâ⬠(1. V. 17-23). Woman knows her better half Macbeth is excessively honorable and guiltless to hurt a person for his very own benefit. She realizes she should convince Macbeth to kill Duncan with the end goal for him to become lord. Afterward, during the celebratory supper, Lady Macbeth persuades a reluctant Macbeth to execute Duncan. From the start, Macbeth is reluctant on the grounds that he thinks he is betraying trust with the lord, he is his brother, and today around evening time Duncan is his visitor. In addition, Duncan has done no wrong to merit demise. Macbeth admits to Lady Macbeth he can not kill Duncan nonetheless, Lady Macbeth says, ââ¬Å"Art thou afeard/â⬠¦Wouldst thou have that/Which thou esteemââ¬â¢st the decoration of life/And live a quitter in thine own esteemâ⬠(1. vii. 43-47). Woman Macbeth is testing his masculinity by considering him a quitter. She is controlling Macbeth by playing with his instabilities and leaving him confounded and in a helpless state. Woman Macbeth exploits the second and persuades Macbeth to kill Duncan to demonstrate he is a man and deserving of his masculinity. As the supper goes on, Lady Macbeth keeps up an ideal veneer of a guiltless, delicate host wearing white outfit. Be that as it may, she is beguiling everyone on the grounds that as the watchmen drink and gathering the night away she binds their beverages to thump them. Consequently, later the fault of Duncanââ¬â¢s murder can be put on their heads. After 12 PM, Macbeth murders Duncan and he is humiliated and distrustful. Macbeth is appalled at himself notwithstanding, Lady Macbeth persuades him ââ¬Å"My hands are of your shading, yet I disgrace/To wear a heart so white/â⬠¦ A little water frees us from this deedâ⬠(2. ii. 83-87). She controls Macbeth in deduction the homicide of Duncan is only a stage to finish his wants. She finishes the homicide and assists Macbeth with washing his hands just as hers. She consoles him they won't be gotten on the grounds that she keenly sedated and put the bleeding draggers in the guardââ¬â¢s hands. What's more, clarifies their main story as being snoozing while this unpleasant deed occurred. Additionally, Lady Macbeth utilizes her visually impaired aspiration and deception to control Macbethââ¬â¢s choices and trick the people around them to accomplish Macbethââ¬â¢s wants and complete the witchesââ¬â¢ predictions. Thirdly, Macbethââ¬â¢s dull wants begin to change Macbeth from a respectable officer to a despot and a degenerate lord therefore, of the control from the witchesââ¬â¢ and visually impaired aspiration from his better half â⬠Lady Macbeth. Toward the start of the play Macbeth is applauded for effectively vanquishing the foe and his military nearby his dedicated friend and solider, Banquo. After the fight, King Duncan acclaims Macbeth as, ââ¬Å"O valiant cousin, commendable gentlemanâ⬠(1. ii. 26). The commendation gives Macbeth incredible regard and respect on the grounds that ââ¬Ëcousinââ¬â¢ is alluded to a person who is profoundly trusted and regarded. Macbeth is applauded on account of his aware deeds of ensuring the lord and dispensing with the adversary danger. The great words Duncan says to Macbeth respect him in a positive manner. Be that as it may, not long after the witches disclose to Macbeth the predictions; the subsequent prescience turns out to be valid and he is granted the tile of Thane of Cawdor. Macbeth goes to King Duncanââ¬â¢s stronghold to tell him of his gratefulness towards the nice thought. In any case, at the stronghold Macbethââ¬â¢s wants begin to change. Duncan reports his oldest child, Malcolm, will be the beneficiary to the seat after his dying. Macbeth says in an aside, ââ¬Å"Stars, conceal your flames;/Let not light observe dark and profound desiresâ⬠(1. iv. 57-58). The seed that the witchesââ¬â¢ are liable for planting within Macbethââ¬â¢s honorable musings prior begins to advance into less respectable contemplations of turning out to be above all else. Presently Macbeth is beginning to feel desirous towards Malcolm. He attempts to persuade himself that such negative considerations are bad and ought not stay in his brain any further. Also, Macbeth is terrified and trusts nobody knows about his negative contemplations towards Malcolm. Besides, Macbeth presently worries about the concerns of two homicides; of King Duncan, and his old buddy Banquo. In any case, he starts to feels uncertain by and by due to the apparitionââ¬â¢s expectation of monitoring Macduff. Macbeth states, ââ¬Å"From this second/The very firstlings of my heart will be/The firstlings of my handâ⬠(4. . 166-168), and arranges in a hurried choice to execute each living soul in Macduffââ¬â¢s stronghold so he can rest better around evening time. The nonsensical request to butcher blameless individuals in Macduffââ¬â¢s manor demonstrates how Macbeth is mishandling his capacity of ruler. Macbeth is rebuffing Macduffââ¬â¢s honest family for Macduffââ¬â¢s treachery. In any case, Macduffââ¬â¢s family isn't even min dful of Macduffââ¬â¢s choices and Violeta Mccarterhttp://www.blogger.com/profile/02705446514355823397noreply@blogger.com0tag:blogger.com,1999:blog-1687764708120168264.post-47170863882134282412020-08-21T20:41:00.001-07:002020-08-21T20:41:31.952-07:00Australia In The Global Environment Pearson ââ¬Myassignmenthelp.ComQuestion: Examine About The Australia In The Global Environment Pearson? Answer Introducation In impeccably serious market, advertise powers for the most part decides cost of item and administrations. In this market structure, the organizations face gigantic rivalry from different rivals as far as evaluating methodology. The central point that adds to ascend in tomato cost in Australia are climatic conditions, laws and guidelines received by the Australian government, buyers and the contenders existing in the market (Bade and Parkin 2016). This is shown with the assistance of outlines given beneath: Figure 1: Price changes Source: (As made by creator) The above figure mirrors that balance happens at the point E where the interest for and gracefully of tomatoes gets proportionate. Comparing to this balance point E, the harmony cost and amount of tomatoes is resolved at P and Q individually (Bade and Parkin 2016). Debbie storm colossally influenced the complete creation of tomatoes in this country. Therefore, the flexibly of tomatoes turned out to be less in the Australian market attributable to this staggering violent wind. This moves the gracefully bend to one side that is signified by S1. This makes lack of tomato in the market as the interest for it stays steady which reflects ceteris paribus. Be that as it may, abundance request emerges in the market. For controlling this condition, the merchants increment the cost for achieving higher benefit (Bade and Parkin 2016). This prompts decrease in amount requested for tomatoes because of increment in cost. In this way, increment in value moves the harmony point to E1 where the new gr acefully bend and request bend meets one another. At this value P1, the amount provided decreases to Q1 from the first balance amount (Q). Thus, this mirrors Debbie storm antagonistically influenced the simply serious market of tomatoes in Australia. b) As the providers diminish the creation of tomatoes, it prompts lack in gracefully of tomatoes in the horticultural market of Australia. This is thusly influences the food business in this country. Moreover, the canned food items produced using tomatoes that incorporate tomato ketchup, canned tomatoes and so forth are antagonistically influenced from this ascent in cost of tomatoes (Bade and Parkin 2016). As the handled results of tomatoes are considered as correlative merchandise, flexibly of these items decays attributable to diminish underway of tomatoes in this serious market. This is represented in the graph given beneath: Figure 2: Impact of ascend in cost of tomatoes in different markets Source: (As made by creator) It has been noticed that, if there should arise an occurrence of corresponding merchandise, if the interest for a specific item diminishes because of full scale ecological components , the cost of another item increments. It has been expressed by Bade and Parkin (2016), interest for one great contrarily influences the cost of another great if there should be an occurrence of correlative products. A portion of the key considers that aides deciding the value flexibility of interest for a specific item are : Accessibility of substitute item The interest for the item able to be versatile if close substitute for the item is accessible in the market. On the off chance that the item isn't accessible, at that point the individuals plan to buy that product regardless of whether value rises. Accordingly, the interest is considered as versatile. As tomatoes have close substitute of vegetables, its interest will in general become versatile. Absolute cash spent by the customers on that specific item The higher the measure of purchasers pay spent on that specific product, higher will be value flexibility of interest. As Australian family units spent gigantic extent of salary in buying tomatoes, the item will in general become flexible. Complementarities between the wares corresponding products likewise impact value flexibility of interest. For this situation, the interest gets inelastic, as family units are less delicate to the variety in product costs. Notwithstanding, as the prepared results of tomatoes are correlative, the interest is supposed to be inelastic. Time skyline The value flexibility of interest will in general become versatile if the complete time associated with creating the item is long. Inclinations of purchasers The value flexibility of interest likewise relies upon the inclinations and needs of buyers. As tomatoes are profoundly favored by the Australians, the interest for this item turns out to be exceptionally flexible. Value versatility of interest alludes to the variety in amount requested as for vacillation in ware cost. It has been opined by Bade and Parkin (2016), a product is named as value versatile, if the variety in amount requested gets higher than its cost. Despite what might be expected, if there should be an occurrence of inelastic interest, change sought after for amount is low in examination with the value alteration. The interest flexibility of tomato adept to be versatile as it has close substitute in the market. Tomato isn't considered as need vegetable and hence reaction popular for all out amounts of tomato will in general be higher as for littler extent in its cost. This implies if the adjustment in cost of tomato is by 1% in this market, at that point the effect on amount requested for this item able to be higher (Bade and Parkin 2016). The Australians who have lower per pay or inclination for tomatoes, it may prompt lessening in amount requested inferable from ascend in cost for this product in absolutely item market of Australians. Be that as it may, the makers or the ranchers are unfavorably affected by violent wind. As it were, flexible interest bend of tomato is compliment than the first interest bend. Figure 3: change in all out income Source: (As made by creator) b) The primary point of the merchants is to accomplish higher income than all out creation cost for increasing higher gainfulness. The all out income of the firm is assessed by increasing item with its all out amount provided (Bade and Parkin 2016). The absolute income of the firm selling tomatoes in Australian market is appeared by the zone P0E0Q0O. As the value flexibility of interest for tomato is versatile, all out income in the market decreases , which is featured in the above figure. At showcase harmony, the income acquired is PEQO. As the all out creation of tomatoes diminishes, the dealers attempts to expand the cost of the product as no adjustment popular for its amount has been watched. In this manner, it has been noticed that, climb in cost of tomato is more prominent than decrease in deals volume of tomatoes, the all out income diminishes in discount market of Australia. This thus debilitates the dealers in further selling tomatoes in the Australian market (Bade and Parki n 2016). On the off chance that gigantic number of ranchers quits creating tomatoes and leave the market, it unfavorably influences the discount market of Australia. This prompts radical fall in flexibly of tomato and subsequently this causes quick increments in item cost. Increment in cost of tomato and this causes decline in all out income got by the ranchers (Bade and Parkin 2016). The ranchers makes huge measure of tomato so as to keep tremendous deal in winter season and put immense sum in gathering it. Basically, ranchers bring about enormous misfortune as the expense of speculation by the ranchers is high and income got is lower than this cost (Bade and Parkin 2016). The fundamental thought process of the ranchers is to put a segment of got benefit in the creation of tomatoes for the up and coming year. Nonetheless, on the off chance that the ranchers bring about misfortune from the offer of tomatoes, at that point they face colossal trouble in delivering it in the following time frame inferable from nonattendance of appropriate store. Therefore, the famers leave the market as the activities of the creation of tomatoes in Australia in long haul turns into not any more gainful to them. Also, the administration of Australia assumes a gigantic job for bringing long haul manageability in Australian market and thus sponsorship is given to the ranchers to taking care of the creation expense. It helps the ranchers in covering colossal misfortune that is brought about to them and supports them monetarily in assembling tomatoes for the following year. The chart beneath connotes the positive effect of sponsorship to the ranchers in the Australian market. Figure 4: Impact of sponsorship on the ranchers Source: (As made by creator) Arrangement of sponsorship gave to the ranchers to every unit of creation decays trouble on ranchers and this builds flexibly of tomatoes. This moves the gracefully bend to one side from S to S1 and this prompts fall in cost of tomatoes. The Australian government bears the creation cost in part by forcing endowment to the ranchers. Consequently, the flexibly bend shifts as for every unit of endowment. Besides, burden of endowment encourages the ranchers in picking up benefits in a lot simpler way, which they utilizes in assembling tomatoes by executing new innovation. As expressed by Bade and Parkin (2016), the legislature receives another system in attempted warehousing venture. In this way, appropriate warehousing helps in improving putting away procedure of tomatoes for expanding stock, which thusly raises stock for smoothening gracefully of tomatoes in the Australian market when tornado hits the country. Points of interest of appropriation Sponsorship gives advantage to the ranchers and the preferences identifying with this appropriation are: Balancing out framework of agribusiness As appropriation offers money related help to the ranchers that thusly helps in buying gear of cultivating and executing new innovation in assembling more tomatoes (Bade and Parkin 2016). Overseeing flexibly of tomatoes-endowment upgrades collect of tomatoes and this builds food gracefully.

What people often do not know is that there are far more mysteries further above the clouds and the airplanes, and the night sky where only the moon and the stars are seen. Outside of planet earth and the solar system, there are a thousand other planets and a huge amount of unknown left for humans to discover. The only way to learn about the mysterious and limitless universe is to explore it, and humans are the pathfinders to discover more about the outer space. Space exploration is one great advance of mankind and is worth the amount of money spent on investment because it allows humans to discover more about the universe and locate valuable resources, and is creating beneficial advancements in fields including technology and medicine. While exploring space, humans can make discoveries in the universe to gain more knowledge about it and find many beneficial resources. One of the purposes of space exploration is to discover more in space and observe them. Two years ago, scientists found the star Proxima Centauri that lies only 4.2 light-years away from Earths sun. In August 2016, they discovered a planet orbiting in Proxima Centauris habitable zone, increasing the possibility that life might have evolved there. This newly discovered planet Proxima b, with a minimum mass of about 1.27 times Earths mass, has a great chance of being a habitable planet (Cofield). During space exploration, scientists may locate another habitable planet where humans can move to live on if earth becomes inhabitable or even new species. Humans can learn about the unknown in the outer space and have a learn more about other planets in the universe except earth. As humans are using the resources on earth at a fast rate, our planet would not have enough resources to use, while the outer space contains essential resources for earth to use.In space, humans are able to find reso urces such as precious rocks and other minerals. Solar energy in space and metallic asteroid from the moon are examples of resources in space. Raw materials from asteroids are mined near earth asteroids, and are then harvested and processed into refined and usable supplies that can be manufactured into finished products. These can only be found in space and contain high abundances of water and important elements (Asteroid Mining). Water and other precious is abundant in the solar system and is necessary to life both on earth and in space. Water is important because it supports humans with drinking water, agriculture, and is the basic of all lives. Space exploration not only allows humans to discover more about the outer space, but also leads to the creation of advancements in technology and medicine. Space exploration allows humans to create the most advanced technological and medical developments. As President John F. Kennedy stated, medical space research may revolutionize the technology and the techniques of modern medicine (John F. Kennedy: Remarks in San Antonio at the Dedication of the Aerospace Medical Health Center. November 21, 1963.). Advancements made during space exploration strongly benefit because they the technology and medical can be used to develop new inventions. Technology used in space programs led to the creation of commercial products such as the water purification system, satellites, satellite television, and GPS (Benefits Of Space Exploration.). Using satellites, humans can receive television programming from a communication satellite orbiting the earth that delivers it directly to the viewers location and use GPS to get information about location and time. The technology advanced from outer space proves to be another advancement of mankind. Both a satellite sent into space and an electronic pain-control device implanted in a patient are only possible because of the development of space programs. Space exploration has also led to the creation of new and improved medical equipment including cancer detection devices, small heart pumps and laser eye surgery (Benefits Of Space Exploration.). Scratch-resistant lenses for eyeglasses and dental braces are also examples of medical advancements from space exploration. Heart pacemakers work through electronic monitoring, which is similar to ones used to operate satellites orbiting the earth (CNN). In addition, the kidney dialysis machines were discovered during a NASA project and the technology was created for purifying water while in space (Admin). Now, the kidney dialysis machine can filter blood for patients who experience kidney failure. These devices were first made for space exploration, but were later modified as medical advancements to benefit patients in need. The advancements made by space exploration are beneficial to humans in the medical field as well. This is a graph of the core focus of space exploration by NASA in 2016. As seen on the graph, exploration and space operation uses most of the budget, costing 8.5 billion dollars. Other fields of science and physics make up the rest of the core focuses. Altogether, the total amount of money spent on space exploration by NASA in 2016 is about 13.65 billion dollars. Some might say that the money spent on space exploration is too much and do not benefit human lives on earth. The total annualbudgetof space agencies in the United States is estimated to be $41.8 billion (Space Exploration Pros and Cons: a Waste of Money?).$41.8 billion is a large amount of money, and can be used to make many other advancements in other fields that are more beneficial to humans. However, the benefits and returns of space exploration creates infinity more wealth than the money invested. The gains from space exploration is not able to be calculated by the amount of money because the discoveries and advancements it brings back is beyond price. The advancements are not able to be made without space exploration, and will not be able to benefit humans. The amount of money spent on space exploration is worth the cost because the benefits include new discoveries and resources in space and more advanced developments in technology and medicine. Discoveries lead to a better understanding of space and essential resources such as minerals are found. Advancements made by space exploration benefit human lives in many ways such as new innovations and advanced medical equipment. As humans are exploring space, they are actually contributing to the advancement of discovering more of the world.

These organs form and excrete urine, regulate fluid and electrolyte balance and act as endocrine glands. The attempt to give a description of what a tumour is is hopeless simply because there are several tumours with different origin and characteristics and there are several concurrent causes of tumour development.Tumours have no specific structure, due to its many forms but mostly they occur in cells. Kidneys, on the other hand, have a definite structure. As illustrated by Jean Hamburger et al., It comprises of renal veins and capillaries that play a pa rt in blood supply to the organ and nephrons that filter blood to generate a filtrate composed of water and soluble (glomerular filtration). Which then passes through a tubule that progressively modifies the filtrate, mainly by reabsorbing desirable solutes and water. The complicated structure of the renal vascular system is crucial for the proper functioning of the kidney.Tumour growth is a simple exponential process terminated by the exhaustion of the nutritional support provided by the host. In most cases tumour growth is smoothly curvilinear on a semi à ¢Ã¢â ¬ log plot throughout observed growth. This shows that the specific growth rate of tumours is usually not constant even for a short time, but can decrease steadily. Tumour formation is a very complex process and it involves many types of changes in the normal cell. Tumour evolution involves straight rounds of mutation and ordinary variety. For tumours to grow without limits, the tumour cells must be able to motivate the p rogress of the blood vessels to bring the nutrients and oxygen. They usually grow by various mechanisms e.g. the host vascular network expands by growing of endothelial sprouts or angiogenesis. Its growth is dependent upon new blood vessel formation; all solid tumours, irrespective of their tissue of origin, the specific oncogenes or tumour suppressor genes expressed.Tumour angiogenesis takes place when there is staffing of new blood vessels synchronised by the manufacture of angiogenic stimulators including members of the fibroblast growth factor and vascular endothelial growth factor families. It enhances entry of tumour cells into the circulation by providing an increased density of immature, highly permeable blood vessels that have minute cellar covering and less intercellular junctional complexes than normal mature vessels. In Kidneys, quiescent endothelial cells have long half à ¢Ã¢â ¬ lives and are protected by autocrine signals such as vascular endothelial growth factor ( VEGF), angiopoietin and notch. These cells are surrounded by pericytes, which secrete paracrine signals such as VEGF and angiopoietins to maintain endothelial cell homoeostasis. When these cells are exposed to angiogenic stimuli pericytes, detach from the vessel walls via the antagonistic role of angiopoietin permitting these cells to develop. Among several angiogenic factors, VEGF is thought to play an artificial role in the maintenance of peritubular capillaries.In Tumours, Hypoxia results from an imbalance between the cellular oxygen consumption rate and the oxygen supply to the cells. It typically occurs in an extensive series of hard tumours due to abnormal vasculature; it affects many natural procedures at molecular, cellular and tissue levels. Adaptive responses to oxygen deficiency shape signal transduction, cell metabolism, proliferation, etc. and thereby contributing to tumour invasion and metastasis. Usually, the presence of tumour hypoxia is largely associated with poor prognosis and therapy resistance. In kidneys, hypoxia occurs when there is a loss of peritubular capillaries preventing the redifferentiation of regenerating tubules; this is turn decreases VEGF expression in these tubules and maintains the hypoxic state through impaired angiogenesis forming a vicious cycle between de à ¢Ã¢â ¬ differentiated tubules with decreased VEGF expression resulting in capillary rarefaction (Luoto et al.

Motivation Audio signal processing has been a very active research area. Automatic piano music transcription, of all the tasks in this area, is an especially interesting and challenging one. There are many examples of how this technique can contribute to our life. For instance, in todayââ¬â¢s music lessons and tests, we often rely on peopleââ¬â¢s hearing ability to judge whether a piano player performed well based on whether the notes played are accurate or not. The process requires man-power and is not always fair and accurate because peopleââ¬â¢s judgement is subjective. If a good automatic transcription system can be designed and implemented with highâ⬠¦show more contentâ⬠¦To tackle this problem, source-separation techniques must be utilized. 2. Existing Approaches In this section, we will discuss what has been done in this area of unsupervised music transcription. Undoubtedly there are different aspects to this task. And different ways and techniques are used in attempt to solve this problem efficiently and accurately. In an effort to provide a clear picture of what has been done, we will categorize different approaches based on technique used. The classic starting point for the problem of unsupervised piano transcription where the test instrument is not seen during training, is a non-negative factorization of the acoustic signalââ¬â¢s spectrogram [1]. Most research work has been improving on this baseline in the one of the following two ways: better modeling of the discrete musical structure of the piece being transcribed [2,3] or by better adapting to the timbral properties of the source instrument [4,5]. Combining the above two approaches are difficult. Hidden Markov or semi-Markov models are widely used as the standard approach to model discrete musical structures. This approach needs fast dynamic programming for inference. To combine discrete models with timbral adaption and source separation, it would break the conditional independence assumptions that dynamic programming rely on. Previous research work to avoid this inference problem typically postpones detailed modeling the discrete structure of timbre Violeta Mccarterhttp://www.blogger.com/profile/02705446514355823397noreply@blogger.com0tag:blogger.com,1999:blog-1687764708120168264.post-26294390442102547992020-05-19T04:43:00.001-07:002020-05-19T04:43:04.364-07:00Maslow s Hierarchy Of Needs Theory - 953 Words Merriam-Webster (n.d.) defines motivation as ââ¬Å"the act or process of giving someone a reason for doing something.â⬠In the XXXXX of a day, employee motivation is fueled by personal and contextual factors that impact engagement and performance. Both factors influence the employee, but do so based on the individual physiological or psychology need of the employee. Kinicki and Fugate (2012) introduces Abraham Maslowââ¬â¢s Hierarchy of Needs Theory as being originally based on research conducted on phobic individuals. PBS (n.d.) defines Maslowââ¬â¢s work as that which is contradictory to those before his, and is determined to understand a humanââ¬â¢s positive mental state. Maslow argued that the human psyche is tiered, not unlike a step ladder and theâ⬠¦show more contentâ⬠¦Maslowââ¬â¢s, McClellandââ¬â¢s, and Herzbergââ¬â¢s theories can fundamentally motivate an employee to either engage in a positive or negative manner. The needs of an individual can be general, resulting in job satisfaction and content, or all-consuming, resulting in unethical behavior or contentment. Understanding both Maslowââ¬â¢s and McClellandââ¬â¢s need theories this author is able to contextualize the chapter six opening case by stating that each of the four characters mentioned enjoy their jobs but wouldnââ¬â¢t mind some minor changes. The first, Lori Miller meets Maslowââ¬â¢s first three levels, but lingers on step four as she longs for relationships lost; Herzbergââ¬â¢s definition of zero midpoint as good hygiene factors have been reached, yet there is no job satisfaction due to the monotonous tasks of the day; and McClellandââ¬â¢s need for affiliation as there is a desire for the social environment. Elizabeth Gray and Frank Gastner, the second and third individuals seem to have also achieved the first three levels of Maslowââ¬â¢s Hierarchy and are desiring the respect of others in the way of equality and autonomy. With their stories enter Herzbergââ¬â¢s motivator-hygiene theory by displaying their job dissatisfaction due to poor administration a nd political working conditions, as well as McClellandââ¬â¢s need for power with their desire resolve issues without corporate politics and red tape.

Robert Frost uses the world around him to create a mystic feeling to his writings, almost giving the reader a sense of nostalgia. The influence of nature in Frostââ¬â¢s works creates a palette to paint a picture filled with symbolism for the reader to interpret. The nature in the poems makes the poem an intimate piece in which most readers can identify with or imagine in some way because of the intense imagery used. In the analysis of Robert Frostââ¬â¢s The Road Not Taken, Nothing Gold Can Stay, and Stopping By The Woods On A Snowy Evening we can pick out specific examples to illustrate Frostââ¬â¢s overallâ⬠¦show more contentâ⬠¦Natureââ¬â¢s first green is gold, Her hardest hue to hold. Her early leafââ¬â¢s a flower; But only so an hour. Then leaf subsides to leaf. So Eden sank to grief, So dawn goes down to day. Nothing can stay. (p.810) The natureââ¬â¢s change from green to gold symbolizes how nothing can stay and live forever. Everything must come to an end. Nature is a constant reminder to humans of our limited time on this earth and Frost uses this fact to illustrate to the reader the power and beauty of our existence. nbsp;nbsp;nbsp;nbsp;nbsp;Frost uses nature in another interesting way in his writing. Nature becomes a potent way to give the reader intimacy into the speakerââ¬â¢s thoughts and choices. In the poem The Road Not Taken, we find an unrivaled use of imagery and symbolism representing the speakers choiceââ¬â¢s about life. I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and Iââ¬â I took the one less traveled by, And that has made all the difference.(p.804) The speaker is torn between two choices in life but takes the harder choice and it has changed his or her life forever. Many people face this situation everyday and choose the easy way and never challenge themselves.

We have revolutionized and constructed a set of boundaries and norms to which the citizens in our society must uphold to. My group decided to conduct experiments on conformity and how it affects people today. So, what exactly is conformity? Our book ââ¬Å"Psychology Perspectives and Connectionsâ⬠defines conformity as the tendency of people to adjust their behavior to what others are doing or to adhere to the norms of their culture. To go along with conformity, social norms are rules about acceptable behavior imposed by the cultural context in which one lives. â⬠¨A couple of weeks ago when theâ⬠¦show more contentâ⬠¦This is just one of the few ways we often conform in our everyday lives.â⬠¨If you think about it people conform all the time. In class Dr. Montesinos asked the class if we could imagine a worl d where nobody conformed. This idea intrigued me because while a world without conformity can be imagined, it is hard to imagine what would come of it in the long run. Carolyn spoke about how everything would be chaotic and nothing would be organized in the world. The human population would greatly be affected if there was no social code or there were no rules for anyone to follow. Conformity plays a crucial role to keeping our society in conditions that are suitable for living.â⬠¨ Conformity can be broken down into two separate branches. Informational social influence and normative social influence. Informational social influences are conformity to the behavior of others because one views them as a source of knowledge about what one is supposed to do. Normative social influence conformity can be defined as conformity to the behavior of others in order to be accepted by them. A simple example of informational social influence would be if you walked by a large group of people looking up into the sky your first reaction would be to look up in the direction in which everyone else is. An example of normative social influence especially in todayââ¬â¢s society would be consuming drugs or alcohol.

Answer: Case Study Analysis The Problem with the case study of Google is that in spite of legendary achievements the company tried to measure performance, satisfaction of the member and conflict as well as level of cohesion. In that view, the company invested millions of dollars for collecting data from 180 teams all through the company. The company also evaluated the beliefs, views and contributors of each team. Further, the problem is also because of dividing the team according to personality, experience, age, gender and education of the employee in the organization. The project also examined based on some assumption of popular wisdom. In the research conducted puzzles have been observed with an evaluation done by the identical makeup and overlapping membership, but with various level of effectiveness. Despite having the good and achievable performance, the company moved for creating a project with the aim of getting best and more satisfaction level for achieving the target of the company. Causes: While evaluating the project of the team performance the evaluator thought of slicing and dicing the team for observing the patterns which will be distinguishing the successful and unsuccessful team. Further, the evaluation was done by optimizing team profile by combining the characteristics of the team member. The evaluation also observed the various pattern like how frequently the members of a team were having the lunch together, with whom they were getting engaged in the free time, whether they were getting engaged with the office people or with the other outsider. There were various reasons, of then issues in the company. The case study also has a problem with the leadership style, team managers of the company. Moreover, the company has done an evaluation by demography of the company. The researcher has done an evaluation by some assumption. While evaluating a performance of the team assumptions should not be taken into consideration. Solutions: Performance can be evaluated by comparing and aligning the strategic business goal of the company. A visibility needs to be provided for clarifying the accountability of the expectation of the performance. A document needs to be present in a case of every employee for measuring the expectation and performance of the employees. The establishment needs to be by focusing on skill and improvement of the activity which has been chosen by the company. Further, it can be said that a support team needs to be present for taking care of the evaluation performance should be by each and every category of employee. It is suggested that fundamental strategies, indirect measurement and interval timers with cycle counters can be used for measuring the performance of the team. On overall the analysis of the case study it has been noticed that company has taken an inappropriate decision in the context of evaluating a performance of the team. The performance of the team should be evaluated through some statistical method and some tools for measuring the performance can be utilized for highlighting the team effectiveness in the organization. There is various process involved in measuring the performance of the team members in the company.

So, when studying in high school , I choose my major including science subjects such as Math, Chemistry and Physics. Many young individuals think that I am very brave because it is too hard for a girl to be a scientist, especially in Asia. Until now, I never feel regret to choose this way. I chose University of Science to complete my goal. Unluckily, I failed my major that is Chemistry, so I was quite shocked a little time. However, I stood up by the support of my family, friends, continuing my path. I studied Physics which can be my last chance to make dream come true. In two first semester, I even try hard but my results are not good, even I failed a subject. Sometimes, I has been really exhausted for a while. I thought it is better for me to drop out of this university and begin again. This thought reminded me whenever I was tired. However, when starting my major in Physics, I was attracted to Applied Physics that allows me to study about optics devices, measuring wavelength and thin films technology. I seem to be confident and step by step studying by my efforts as well as my passionate. The moment when I met lecturers belonging from my major who have taught me a lot of base knowledge about thin films technology, which encourages me to go hard to achieve my goal. Moreover, I and my friends also learned many practice skills from these professional individuals, which allows us to be more mature and understanding. Thus, I was appreciated remarkably . When being a third-year student, I spent a lot of hours to study at home as well as online courses. Honestly, it is hard to study in English because it is a second language for me. I bent over backwards as much as possible to get certificates of passing grade. This has proven that I am strongly willing to study. Therefore, I mainly think it is my highest advantage. In addition, I am fascinated about reading books and looking for something new around. When semester begins, I plan my schedules reasonably in order to get best results. Additionally, I was keen on taking part in sport activities in university and then obtained a certificate , which proves me to be healthy. Now, Iââ¬â¢m becoming a senior student. When times goes by, there are too many things that I want to do by my best.

He was an extreme example of the celebrity stereotype flashy, arrogant, self-absorbed, and rude. Stark took personal honors, as well as relationships with others, for granted. But that all changed when Stark was kidnapped by a terroristic rebel group. During his time as a prisoner, Tony saw what horrors his technology could be used for, and later escaped captivity humbled and changed. From the moment he returned, Starkââ¬â¢s character started growing into a caring and heroic figure. Specifically, Tony Stark emerged as a new man, actually caring for his assistant, Pepper Pots, being concerned about what his technology is used for, and becoming Iron Man to save others. In the beginning of the film, it became apparent that Pepper Pots did quite a lot for Tony. We will write a custom essay sample on Iron Man Character Analysis or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page She was his manager after all. Although, portraying his original shallow character, Stark didnââ¬â¢t ever really seem grateful to her for what she did for him, and would just rattle off tasks for her to do. At one point, he even forgot Pepperââ¬â¢s birthday, saying, ââ¬Å"Its your birthday? Well, get yourself something nice for meâ⬠. (Iron Man) This quote truly shows the disregard that Stark had for his assistant, and the disconnect between the two. Fast forward to after Tonyââ¬â¢s capture, and while attending one of his social functions, Stark danced with Pepper for quite a while, making meaningful conversation. The two even almost kissed. lThroughout the movie, Tonyââ¬â¢s caring grew for Pepper, with him saving her from Obadiah Stane, the eventual villain of the movie. At one point, when Pepper told Tony that he is all she has, Tony replied with, ââ¬Å"Youââ¬â¢re all I have tooâ⬠. (Iron Man) At the conclusion of the movie, the stage was set for the beginning of Tony and Pepperââ¬â¢s relationship, which was truly a 180 degree turn from where the two began the movie. Another such change was when Stark started caring where his shipments of weapons went. At the start of Iron Man, Stark Industries weaponry was distributed all over the globe with little, if any, concern to where it ended up. Oftentimes these extremely powerful weapons ended up in the wrong hands, like insurgents. When Tonyââ¬â¢s convoy was attacked, a rocket lodged into the ground in front of him, bearing the inscription of Tonyââ¬â¢s own corporation. Upon his return, having seen the horrors of his weaponry firsthand, Stark set out to right the wrongs. At his first press conference after coming home, Tony said, ââ¬Å"I saw young Americans killed by the very weapons I created to defend them and protect them. And I saw that I had become part of a system that is comfortable with zero-accountabilityâ⬠. Iron Man) He then proceeded to shut down the weaponry arm of Stark Industries. These actions are the sign of a changed man. Tony Stark went from war profiteering to whistleblowing for corrupt arms dealing. Finally, Tony Starkââ¬â¢s most obvious change was simply in becoming a superhero. From the start of the movie, Stark was a rich, self-interested playboy who would be more concerned over a scratch on the finish of his Audi R8 than the fate of the free world unless it benefitted him. Taking a completely different direction, Tony used his Iron Man suit to pursue those who wrongfully used Stark Industries weapons. Stark even stated, ââ¬Å"I shouldnt be alive unless it was for a reason. Im not crazy, Pepper. I just finally know what I have to do. And I know in my heart that its rightâ⬠. (Iron Man) This quote was referencing his decision to pursue justice against those who were previously mentioned. It was amazing to see Tony Stark go from some disinterested rich guy to a full-blown superhero, dealing justice through his high tech suit of armor. In the ways of turning around oneââ¬â¢s life, Tony Stark may have been one of the most extreme examples in cinema. He went from a callous, self-absorbed playboy to an absolute comic book hero. On the way to becoming such a hero, Stark gained quite an appreciation for his assistant, Pepper Pots, righted wrongs that his weapons caused, and became a hero for the oppressed. That was quite a turn around, Tony.

Both the French and the American Revolution stem from ideals of Enlightenment, wherein the public wanted to be free from oppressive and tyrannical rulers, and put power back into the hands of the people. The French revolution was a result of lower classes fighting to overthrow a government within their own country out of a need for welfare and financial security. The people of France were starving as taxes kept rising in order to keep aristocrats in the lap of luxury. The American Revolution started because of the need to feel justice, fairness and equality; America already had a large degree of self government. Britain treated the Americaââ¬â¢s as a territory instead of an extension of their land and their people which resulted in Americans fighting an overseas king to become and independent nation breaking away from British rule. Both the American and the French Revolution had key leaders, impacting the direction each countries Revolution would take. Both the American and the French leaders had a huge impact on how violent each war would turn out to be. Americanââ¬â¢s had Thomas Jefferson and George Washington who helped shape the country, the government, and the people in a positive and significant way; leading to an almost non violent transition. France had leaders who, although are an crucial part of history, didnââ¬â¢t have a constructive impact on the country or the people. Unlike the leaders of America, the leaders of France caused more destruction and harm than good. The French people looked to these leaders for help in deciding which kind of government would be most advantageous for them. Debatably, one of the most prevalent leaders of France was Maximillien Robespierre, who demanded a republic; his demands were met when the monarchy was overthrown, and King Louis XVI was executed. Maximillien Robespierre brought about was the ââ¬Å"rein of terrorâ⬠killing anyone who was in support of a monarchy or tyrannical type government, where up to as many as forty thousand people were killed by guillotine. In the French Revolution, people were fairly split on what they wanted to happen resulting in a radical change of goals throughout the war; which later led to a civil war. The American people sent a Declaration of Independence stating our intention to break away from British rule and become our own independent country. The goals of the American people remained nearly the same from start to finish. The Americans were never violent towards supporters of British monarchy, like the French were. In conclusion, The American and French Revolution were started on the same basic fundamentals such as leaders, enlightenment, and ideology. The French people looked toward America as an example of what they sought for their own country; however, because of the difference in leaders and ideals, each countryââ¬â¢s Revolution took a fundamentally different turn, but having almost the same conclusion. In France, leaders such as Robespierre and Napoleon with their eventual dictatorship helped France rid itself of a monarchy indefinitely, leading to a democracy. In America Leaders such as George Washington and Thomas Jefferson also helped America evolve into a democratic government.

Economics is the study of the forces of supply and the demands allocate deficient resources. Economics is divided into microeconomics and macroeconomics. Microeconomics is something doing with the behavior of firms, consumers, and also about the role played by the government. Macroeconomics is more to inflation, industrial production, unemployment and the role played by the government. Microeconomics is the study about the behavior of small economics unit, for an example, individual consumers or households. Microeconomics is behavior of individual units. Microeconomics main concern is about the factors that affects an individual economics choice. Other than that, economics also can be said as branch of social science that can read the production distribution and the consumption of goods and service. Economics also include scarcity, choice, households, goods and productions as a definition. Economics system are studies of the method and institution where societies determine about the ownership, direction and allocation of economics. There are three types of economics system; Socialist system is a system that can be defined as a centrally planned or can be said as command economics. This system is fully controlled by the government. All the choice about resources are all made by the government. Capitalist system means free market economics. This system is like a freedom economy. This is because of the decisions made by the people. This system is mainly about the people in the country. Mixed economy Mixed economy is an economy based on the free enterprise principle. There is still some form of direct intervention and it is controlled by the government. Mixed economy can be said as a form of organization where both capitalist economy and socialist economy are found. In mixed economy there is the presence of private economic freedom with centralized planning and the common goal of avoiding the problems which comes because of capitalism and social ism. In the mixed economy system the main authorization of the economic activities are mainly by the governmentà ¢Ã¢â ¬Ã¢â ¢s regulation and the licensing policies. For an example, if someone wants to open a business, they must register and take license from the government for that particular business. So in this way, the government becomes a big power in the country. Mixed economy is also known as dual economy. In a mixed economy, the government runs things as post office, libraries, hospital and many more. Even when there is an industry which is not run by the business, still government get taxes and regulation like wage controls. Most of the people all over our country have no problem with the government take control of things like highway construction, birth certificate, national service economy may seem to be very easy as it is but there are some disadvantages in mixed economy also. The biggest disadvantage is between the public and private sector because they easily get b lurred or sometimes shift one way or another from time to time mixed economy usually increase more government control and less individual freedom. This is why mixed economy is always in an evolutionary process.

Something which is ideal to me may not be ideal to others and vice versa. During my management I did my specialization in marketing. Lot of people did their specialization in finance. I think marketing as a subject/course is more ideal than a finance. Before discussing why marketing is more ideal than finance lets first understand what does an ideal college experience means. An ideal college experience means an experience in discovery. It can be related to a particular subject or also personal discovery of self. So an ideal course can be new ways of learning, learning new values, learning new ways of solving a problem or addressing an issue. It is not mere reading a book, remembering a subject and then writing the same in the exam. It is about applying your knowledge and tools to think critically. It is about handling different situations in different ways and finding solutions for all kind of problems Marketing as a subject has got very little to do with theories and concepts. Yes, theories and concepts are important but not from a reading or remembering point of view but from the point of applying it in day to day life. Marketing is about thinking and applying the concept learns during the lecture to handle tricky situation. It is about creating different, new and innovative methods to sell you product or services. It is about creating ideas and strategies. ... That is something a student needs to decide. This is where a student is really tested as in how good is his ability to think and rationalize. Advertisement is a part of marketing. Creating an ad for a particular product or service is a challenging job. That is where the analytical skills of a student is tested. You can judge how creative a student is. Marketing research is also a part of marketing where a student analytical skill is tested. Marketing has got to do with lot of group activities. Where a students learns how to work in a team. He learns the ways to respect you superior and work with you subordinate. Finance on the other hand involves more of theories than practical. Lot of reading is involved in finance. You need to be thorough in the concepts and you need to remember lot of definition. Practical knowledge and activities are very less in finance. Calculation and analytics are important elements of finance but other than that not a lot of all round skills of student is te sted in finance. Further finance has got to with numbers and application of numbers. But when it comes to practical application of finance it definitely is bare minimum. Finance is a very important department in corporate and is essential for any organization. But in studies it has very little do when it comes to group work or applying it in practical purpose. It is mostly theories and concepts and less of practical, creativity and inter-personal skills. Finance is far from being an idea subject because it is one dimensional and does not focus on most of the skills that a student needs to develop. So when you compare a marketing and finance as a subject you will agree to the fact that marketing Violeta Mccarterhttp://www.blogger.com/profile/02705446514355823397noreply@blogger.com0tag:blogger.com,1999:blog-1687764708120168264.post-14806534324931988152020-02-01T01:22:00.001-08:002020-02-01T01:22:02.700-08:00Juvemile justice in America chapter 12 Essay Example | Topics and Well Written Essays - 250 wordsJuvemile justice in America chapter 12 - Essay Example The programme is mostly focused on the thoughts of an individual that leads towards certain undesired actions. These thoughts are because of experiences and other affecting factors. The programme is rooted in the fact that most individuals are aware of their thoughts and behaviours, and that they can change their actions from negative to positive. The change starts from the thoughts and finally the actions taken by the individual. The programme helps individuals to great lengths, it ensures that they adopt a positive line of thought resulting in change of behaviour and equips them with necessary social skills (Bartollas et al, 2014). The above programmes prove to be highly effective however, they are problems associated with them. The behavioural therapy for example rewards positive behaviour and ignores the negative. This type of approach may create further problems when an individual is doing wrong in a bid to seek attention. Ignoring such an individual is wrong because they will try harder to get the attention they seek, creating more Violeta Mccarterhttp://www.blogger.com/profile/02705446514355823397noreply@blogger.com0tag:blogger.com,1999:blog-1687764708120168264.post-27434345916153214742020-01-23T21:43:00.001-08:002020-01-23T21:43:02.919-08:00The Oedipus Complex in Oedipus the King :: Sophocles In Oedipus the King, once upon a time in a kingdom far, far away Queen Jocasta was expecting a baby boy, but one day Tiresias (a blind prophet) dropped by one day to see the queen to give her bad news about her baby. Tiresias said "My queen, the son you will bear will kill his father and marry his mother!!!" The queen was appalled by this news, thus, after the queen had her son she immediately drove him away, by leaving him in the dark, verdant woods. A herder from another kingdom found the baby boy and immediately notified his king about the baby. The king adopted the newborn boy and named it Oedipus. When Oedipus was grown up (in his twenties) he heard a legend that a prince from a kingdom far, far away will kill his father and marry his own mother. Oedipus was frightened that he will kill his father and own marry his own mother so he embarked on a journey to escape the myth. When Oedipus was traveling in his chariot he met a man in the middle of the desert, and the young arrogant Oedipus killed the man. (He did not know that he just killed his biological father) In the gates of Thebes, a sphinx was guarding the kingdom slithering back and forth. Oedipus finally talks to the sphinx, ?Maybe you can spare us some food, my kingdom was shambling into death.? ?Well, well, do you want to enter the kingdom to speak to the queen?. ? ?Yes,? replied Oedipus ?I have a riddle for you my child. If you answer it correctly, you may talk to the queen and you have heard about our king who has been missing for days. We assumed he is rotting in the middle of the desert. I guess the vultures will have a feast? In addition to talking to the queen about your discrepancies you can also marry the widowed queen.? The sphinx asked Oedipus, ?What walks on four legs in the morning, two at noon, and three in the evening?? ?A man,? Oedipus replied and he was correct. So basically he can marry the queen of Thebes and that makes him the king of Thebes. (But keep in mind Oedipus is going to marry his own mother.) The King had the Queen of Thebes four children, two sons, Eyocles and Polynices and two daughters, Ismene and Antigone.

As such, it was tied to a growing international web of economic relations. â⬠By 1820, the South became the worldââ¬â¢s largest producer of cotton. Cotton required continuous development, land, labor demand and a global system of trade. As such, it depended increasingly on the slave-based economy. However, the Upper South was experiencing a long depression and it affected prices. To survive, either the planters move or stay and diversify. Diversification meant shifting to grains and to selling slaves. Soon, the internal slave trade became a multi-million dollar industry. Until the 1830ââ¬â¢s, slavery was explained as a ââ¬Å"necessary evil. â⬠However, the call for abolition of slavery was becoming stronger and they had to change their justification for maintaining slaves to make it more acceptable. The Southerners started to label slavery as ââ¬Å"a positive good. â⬠They based their justifications on five sources ââ¬â the bible, history, the Constitution, science and sociology. The biblical justification makes reference to the curse imposed upon Ham, Noahââ¬â¢s son and the various verses from both the Old and New Testament reprimanding servants to always obey their masters. For its historical justification, they pointed out that all ancient civilizations were based on it and most likely even the current civilization depended ââ¬Å"on the servitude of the blacks in America. â⬠The Constitution was their reference to its legal justification which refused to abolish slavery and various laws passed protecting it such as the overseas slave trade and mandate for returning slaves to rightful owners. They also turned to science and twisted the data an conclusions to justify that blacks were an inferior race based on the cranial shape and size and must, therefore, submit to their destiny ââ¬Å"to work for the superior Caucasians. â⬠Lastly, the sociological justification was made more clear by the paternalistic statement as advocated by George Fitzhugh that the ââ¬Å"ââ¬â¢Negro is but a grown child and must be governed as a childââ¬â¢ and so needed the paternal guidance, restraint and protection of a white master. â⬠Be that as it may, to free the blacks would mean ââ¬Å"giving up our beautiful country to the ravages of the black race and amalgamation of the savages. â⬠On the humanitarian side, they said that it would be heartless to release them especially after seeing that the blacks can only be industrial laborers working like slaves for meager pay from which they will have to use to pay for shelter, food and clothing. They will be a burden to the white people who have to compete for the same job and a burden to themselves for having to fend for themselves without the nurturing protection of a master. These justifications were had to be well-thought of so that it would not run contrary to the prevailing ideological directions of the American society at that time which espoused ââ¬Å"individual liberty, mobility, economic opportunity and democratic political participation. â⬠Moreover, they cannot afford to antagonize the probably envious non-slave owning whites that they had to emphasize ââ¬Å"white superiority regardless of class. â⬠The truth of the matter is that behind all these justifications, the real motive is money. By 1860, the crop per value of a slave is $125. Enslaved women increase their value whenever they give birth to healthy children. A prime field worker which sold for $600 in 1844 can go as high as $1800 following a cotton boom. All things told, what mattered most is that slavery is profitable.

However, father and son disagreed on plans to expandà to Europe, and in the early 1930s, estranged from his father, Forest moved to Europe, where he saw British soldiers fighting in the Spanish Civil War eating Smarties candies ââ¬â chocolate candies with a hard shell, which were popular with soldiers because they were less messy that pure chocolate candies. M MCandies Are Born Upon returning to the United States, Forest Mars began hisà own company, Food Products Manufacturing, where he developed, among other things, Uncle Bens Rice and Pedigree Pet Foods. In 1940 he began a partnership with Bruce Murrie (the other M) and in 1941 the two men patented M M candies. The treats were initially sold in cardboard tubes, but by 1948 the packaging changed to the plastic pouch we know today.à The enterprise was a rousing success, and in 1954, peanut M Ms were developed ââ¬â an ironic innovation, since Forest Mars was deathly allergic to peanuts. In this same year, the company trademarked the familiar Melts in Your Mouth, Not in Your Hand slogan.à Forest Mars Later Life Although Murrie soon left the company, Forest Mars continue to thrive as a businessman, and when his father died, he took over the family business, Mars, Inc, and merged it with his own company. He continued to run the company until 1973 when he retired and turned the company over to his children. In retirement, he started yet another company, Ethel M. Chocolates, named after his mother. That company continues to thrive today as a maker of premier chocolates. Upon his death at age 95 in Miami, Florida, Forest Mars was one of the wealthiest men in the country, having compiled a fortune estimated at $4 billion. Mars, Inc. Continues to Thrive The company begun by the Mars family continues to be a premier food manufacturing corporation, with dozens of manufacturing plants in the U.S. and overseas. A great many name-recognized brands are part of its portfolio, not only candy brands, but also pet foods, chewing gum, and other consumables. Among the brands you may not have realized were related to M M candies and that live under the Mars umbrella include:à Three MusketeersSnickersStarburstSkittlesBountyDoveUncle Bensà Seeds of ChangeKudosBig RedDoublemintFreemintAltoidHubba BubbaJuicy FruitLifesaversWrigleysIamsCesarMy DogWhiskasPedigreeEukanuba Violeta Mccarterhttp://www.blogger.com/profile/02705446514355823397noreply@blogger.com0tag:blogger.com,1999:blog-1687764708120168264.post-25659481572385727532019-12-30T10:54:00.001-08:002019-12-30T10:54:04.260-08:00A Process Whereby the Success to Successful Paradigm Could Be Broken Free Essay Example, 1250 words One of the ways of breaking the loop is improvising devices to break the loop (Meadows, 2009, p. 130). For example, to bridge the gap between the poor and the rich, tax laws can be introduced to reduce the income of the rich. Strict restrictions on how to share the limited resource may also be put in place or revise policies that devise rewards for success so that they do not bias the next round. In this case, although the government puts restrictions on working time, there is no guarantee that the leader would not spend more time on work depending on the reinforcement he is getting for doing so. As such, restricting the time may only cause more problems as the leader may not be able to accomplish his goals within a limited time. It is evidently clear from the discussion that the only sound way thus to strike the work/life balance is to diversify time by introducing flexible time such as flexitime, annualized hours, compressed week, or work at home through the use of technology. Th is requires the restructuring of the work schedule so that the whole organization can function properly during the absence of the leader.

Fashion brands do not shape who we are. Just because someone does not wear designer jeans, does not mean they are poor or ugly or not good enough. What if everyone dressed the same and did not have to worry about how they look or what it says about them? School uniforms are the answer. School uniforms encourage academic success, prevent bullying, and increase safety in schools, making them a positive impact on students. Uniforms encourage academic success through increasing focus and promoting spirit, causing attendance to increase and grades to also improve. ââ¬Å"With noâ⬠¦show more contentâ⬠¦Uniforms are actually cheaper than trying to stay in fashion (Jones 5). Buying a pair of one hundred dollar jeans is much less expensive than buying a whole school uniform for a similar price. Bullying can not only cause mental or physical harm to victims, but harm the bullyââ¬â¢s future. ââ¬Å"Teensâ⬠¦who bully are more likely to engage in other antisocial [or] delinquent behavior (e.g., vandalismâ⬠¦and drug use) into adulthoodâ⬠(Gluck 10). Bullying can affect the victimââ¬â¢s future as well. ââ¬Å"In 12 out of 15 school shooting cases in the 1990s, the shooters had a history of being bulliedâ⬠(Effects of Bullying 4). If bullying over clothes seizes, many other problems will lessen, so uniforms will keep this form of bullying away. Uniforms in school will increase safety because it decreases school shootings and violence. As stated before, bullying can cause shooting which makes school more dangerous. Clothes in general can cause shootings. In Baltimore, a shooting at a public school took place in 1986 over a ninety-five-dollar pair of sunglasses, resulting in a wounded student (Background of the Issue 7). Uniforms would keep such an issue at bay. Violence will decrease too with uniforms.

NOTES BASED ON RESEARCH METHODOLOGY BY WELMAN, KRUGER AND MITCHELL, 3RD EDITION. THE AIMS OF RESEARCH ? ? Research is a process that involves obtaining scientific knowledge by means of various objective methods and procedures. The term objective indicates that these methods and procedures do not rely on personal feelings or opinions and that the specific methods are used at each stage of the research process. We will write a custom essay sample on Research Methods or any similar topic only for you Order Now These methods include procedures for drawing samples (e. g. simple random sampling), measuring variables, collecting information and analysing the information. Research methodology considers and explains the logic behind research methods and techniques. ? ? Sources of non ââ¬â scientific knowledge ? ? The sources include authority, opinion of peers, traditions, debating and accidental observation. Under authority, non ââ¬â scientific knowledge is often merely accepted on the basis of the authority of some or other source. In contrast, with scientific approach, one should check the way in which findings are acquired and not accept them merely because they originate from a so ââ¬â called expert. Non ââ¬âscientific knowledge can also be acquired by asking the opinion of peers. Traditions refer to knowledge which is carried over from one generation to the next. Under debating, people attempt to obtain knowledge and insight by arguing in a seemingly logical manner. Accidental observation ââ¬â this is where we notice something happening in one situation, but do not investigate the phenomenon in a systematic and planned manner ? ? ? ? Core features of scientific knowledge ? ? ? ? They include systematic observation, control and replication. Systematic observation ââ¬â scientific approach requires that we plan an investigation in which we use the results of two groups that have applied the methods. Control ââ¬â scientific knowledge can be obtained in a controlled manner. Control means that alternative explanations for the obtained results should be eliminated systematically. Replication ââ¬â it must be possible to replicate the research results. It means that similar results should be obtained by other researchers including other research participants in other circumstances. 1 Quantitative and Qualitative Research Cycles ? Qualitative implies an emphasis on processes and meanings that are not rigorously examined or measured (if measured at all) in terms of quantity, amount, intensity or frequencies. The aims of qualitative research are to establish the socially constructed nature of reality, to stress the relationship between the researcher and the object of study, as well as to emphasize the value ââ¬â laden nature of the inquiry. Quantitative research methods do not involve the investigation of processes but emphasize the measurement and analysis of casual relationships between variables within a value ââ¬â free context. ? Differences between quantitative and qualitative research 1. The purpose of quantitative research is to evaluate objective data consisting of numbers while qualitative research deals with subjective data that are produced by the minds of respondents or interviewees. 2. Quantitative researchers use a process of analysis that is based on complex structured methods to confirm or disapprove hypothesis. Flexibility is limited to prevent any form of bias in presenting the results. In contrast, qualitative research is based on flexible and explorative methods because it enables the researcher to change the data progressively so that a deeper understanding of what is being investigated can be achieved. 3. Quantitative researchers try to understand the facts of a research investigation from an outsiderââ¬â¢s perspective. Qualitative researchers try to achieve an insiderââ¬â¢s view by talking to subjects or observing their behaviour in a subjective way. 4. Quantitative researchers try to keep the research process as stable as possible. They focus on the causal aspects of behaviour and the collection of facts that wouldnââ¬â¢t change easily. Qualitative researchers work with the dynamic and changeable nature of reality. 5. Quantitative researchers control the investigation and structure of the research situation in order to identify and isolate variables. Specific measurement instruments are used to collect data. The approach is particularistic. Qualitative researchers make use of a holistic approach, i. e. , they collect a wide array of data, e. g. , documents, records, photos, observations, interviews and case studies. In conclusion, the purpose of both quantitative and qualitative research is to try and understand the subjectââ¬â¢s point of view. Quantitative researchers do it by means of controlling the situation and using remote empirical and inferential methods. Qualitative researchers, on the other hand, use unstructured interviewing and detailed observation processes to gain better information about the views of the subject. 2 THE RESEARCH TOPIC, PROJECT TITLE AND RESEARCH PROBLEM The research process This involves: ? ? ? ? ? ? Identifying research topic. Defining research problem. Determining how to conduct the study Collecting the research data. Analysing and interpreting the research data. Writing the report. Identifying research topic ? ? ? ? ? First source of ideas is your own experience and reflection of things around you. Become more aware of current events by keeping up to date with media coverage of worthwhile and interesting phenomena. Become more critical of different viewpoints when they are aired and defended by people in your immediate environment. Read more literature. Listen critically to what people around you are talking about. What are the current issues in the political, social, economic, environmental and other areas. Guidelines for the selection of a research topic ? ? ? Select a topic that is relevant to your own short-term and medium-term career prospects, whether it be a career in research or any other profession. Select a topic that you find intellectually stimulating and that you are convinced will sustain your interest for a number of years. Select a topic that is researchable in the sense that you will be able not only to merely complete it with the available resources, but also complete it at a level of scholarship that is scientifically acceptable. Select a topic that you find interesting and worthwhile. Then read more about it and focus more narrowly, delineating it into a more specific topic. ? Defining the research problem ? ? ? ? This involves narrowing down our general interests in a research topic in order to focus on a particular research problem which is small enough to be investigated. This process leads to the setting of the research questions. You read "Research Methods" in category "Essay examples" In academic research, the classic way to identify a research problem is to consider the literature and identify any gaps. These gaps indicate original areas to research. 3 ? ? ? ? ? A research problem refers to some difficulty that the researcher experiences in the context of either a theoretical or practical situation and to which he/she wants to obtain a solution. To define a problem correctly, the researcher must know what a problem is. To answer a research problem, the researcher must be able to answer the following questions: o What is the problem? o What is the best way to solve the problem? A useful strategy that can be used to identify the research problem involves asking questions. Good questions have the following characteristics: o They express relationship(s) between two or more variables. They are clear, i. e. , what is asked is understood. o Implicit in each research question (research problem) is the view that some variables are the causes of other variables. o The independent variable (X) is that factor which the researcher selects and manipulates in order to determine its effect on the observed phenomenon. o The variable is independent because t he researcher is interested in how it affects the other variables being studied. o The dependent variable (Y) is that factor which the researcher observes and measures to determine how it was affected by the independent variable. The origin of research problems Typical sources of research problems include: ? ? ? Practical problems ââ¬â caused by political, social and economical changes. Previous research ââ¬â from other studies where there are shortcomings or contradictions. Theories ââ¬â should associate a research project with a specific theory. A theory is a statement or a collection of statements that specify the relationships between variables with a view to explaining phenomena. The purpose of research ? ? ? To describe how things are, i. e. , define the nature of the study object. To explain how things are the way they are. Could it be because one thing caused another? To predict phenomena. Research hypothesis ? A hypothesis is a statement or proposition that can be tested by reference to the empirical study. Example, a research question may be: What is the relationship between advertising expenditure and income? 4 A hypothesis dealing with the same question is: There is a positive relationship between advertising expenditure and income. ? ? ? A research question differs from a hypothesis in that the research question is always expressed as a question, while a hypothesis is expressed as a statement. Hypothesis can either be directional or non-directional. Non-directional hypothesis do not predict the direction of the difference or relationship. o There is a difference between the organisational commitment of male and female employees. o There is a relationship between job satisfaction and salary level. Directional hypothesis are used if the researcher is more confident about the direction of the difference or relationship, or if the literature reports that previous studies found differences to be in a particular direction. Female employees have a higher level of organisational commitment than male employees. o There is a positive relationship between job satisfaction and salary level. A null hypothesis states that there is no difference between two groups in relation to some variable, or that there is no relationship between two variables. o There is no difference between the organisational commitment of male and female employees. o There is no relationship between job satisfact ion and salary level. A null hypothesis is indicated by H0 whilst the alternative hypothesis is indicated by H1. E. g. H0: There is no relationship between job satisfaction and salary level. H1: There is a positive relationship between job satisfaction and salary level. ? ? ? Formulating the research hypothesis ? Where possible, we should translate the research problem into a research hypothesis that states a relationship between two or more variables in one (or more) population(s). ? Use the following approach to develop a hypothesis: o Discuss the problem, its origin and the objectives in seeking a solution with experts. o Examine data and records concerning the problem for possible trends and clues. Use secondary data. o Interview interested parties and individuals on a limited scale to gain greater insight into the practical aspects of the problem. 5 NOTES ON LITERATURE REVIEW ? ? Literature review is a review of the existing scholarship of available body of knowledge to see how other scholars have investigated the research problem you are interested in. You learn from other authors how they theorised and conceptualised on issues, what they have found empirically, what instrumentation they have used and to what effect. Elements of Literature review ? ? ? Definitions Different theories, models and hypothesis in the field of research Existing data and empirical findings that have been produced by previous research. Measuring instruments (questionnaires, scales and indices) that have been developed to measure the extent or scope of research. Importance of Literature Review ? ? ? ? ? ? ? To ensure one does not merely duplicate a previous study. To discover what the most recent and authoritative theorising about the subject is. To find out what the most widely accepted empirical findings in the field of study are. Researcher can relate those findings to his/her own study. To identify the available instrumentation that has proven validity and reliability. To ascertain what the most widely accepted definitions of key concepts in the field are. Provides important facts and background information about the subject under study. Researcher can get ideas on how to proceed with the investigation. Planning the Literature Search ? ? ? Plan carefully to locate relevant and up-to-date literature. Define the parameters of your search ââ¬â guided research questions and/or objectives. Generate key words and search terms ââ¬â this is the most important part of planning your search for literature. Key words are the basic terms that describe your research questions and/or objectives. Discuss your ideas as widely as possible ââ¬â with experts and peers. ? Compiling a Literature Review ? Integrating the studies o Literature review should not consist of mere compilation of separate, isolated summaries of individual studies of previous researchers. o You should clearly show how these studies relate to one another and how the proposed research ties in with them. Sources of Literature Searches Primary Literature Sources 6 ? ? ? o These are the first occurrence of a piece of work. They include published sources such as reports and some central and local government publications such as economic surveys, UNESCO reports, the Hansard etc. o They also include unpublished manuscripts such as letters, memos and committee minutes that may be analysed as data in their own right. Secondary Sources They include books and journals that constitute the subsequent publications of primary literature. Tertiary Sources o These are designed either to help locate primary and secondary literature or to introduce a topic. o They include indexes and abstracts as well as encyclopaedias and bibliographies. Search using CD-ROM A CD-ROM contains permanent digitally encoded information on a large on a large scale which may represent text, graphics, images or data and can be accessed very quickly. Examples of CD-ROM databases include: o ABI/INFORM ââ¬â Covers every aspect of business management theory and practice including accounting, computer, human resources, marketing and organisational behaviour. o Anbar ââ¬â Includes subjects such as accounting and finance, information management and technology, management services and production, marketing and distribution, personnel and training, and top management. ? ? ? ? ? ? ? Use of Internet for example Google Scholar, Science Direct, Elsevier etc. Quotations o With exception of direct quotations, the entire research report should be presented in the authorââ¬â¢s own words i. e. without paraphrasing or patching together pieces from other sources. o Use direct quotations sparingly as they are only permitted when something is expressed so eloquently or in such an original way that you feel something will be lost in the process of reformulating it. General guidelines for using quotes in research reports o Incorporate quotations of up to (and not longer than) about 30 words into the text. Enclose the quoted material in double quotation marks. o Apart from the surname of the author and the year of publication, all quotations should also be accompanied by the page number on which the material appears in the quoted source. 7 ? Evaluating the relevance of the literature o How recent is the item? o Is the item likely to be superseded? o Is the context sufficien tly different to make it marginal to your research question(s) and/or objectives? o Have you seen references to this item (or its author) in other items that were useful? Does the item support or contradict your arguments? o Does the item appear to be biased? o What are the methodological omissions within the work? o Is the precision sufficient? ? ? ? ? ? ? The reference system A reference must enable the reader of your research report to locate the information sources referred to if so needed. A reader may want to read more about the issue from the information source. References in the text If you refer to theories, research findings, or any other contribution previously reported, you should give the sources involved due credit. Give the surname(s) of the author(s) followed immediately by the year of publication between parentheses. E. g. In a well-designed experiment, Strauss (1990) found thatâ⬠¦ Do not list a string of references that are not appropriate in the context in which you cite them. Cite sources after identifying their relevance. It should be clear whether the citation is a finding or an opinion that has been obtained from the source. If a source has more than two authors, you should list them all the first time it appears in the report. E. g. Ojah, Muhanji and Myburg (2008) found thatâ⬠¦ In all subsequent references only the surname of the first author is provided followed by et al. E. g. Ojah et al (2008) found thatâ⬠¦ If you refer to the same source more than once in the same paragraph, the date should accompany only the first reference. If there is more than one source with several authors, and they have the first two authors and date in common, give the first three names plus et al in further references to distinguish them. E. g. Smith, Jones, Botha and Tiffin (1990)â⬠¦ 8 ? ? ? ? ? ? ? ? ? ? ? Smith, Jones, De beer and Zwane (1990)â⬠¦ Further references are Smith, Jones and Botha et al (1990)â⬠¦ and Smith, Jones and De Beer et al (1990)â⬠¦ When more than one reference appears between brackets, put a comma between the author(s)ââ¬â¢ surname(s) and date, and a semicolon (;) between the different references. E. g. (Jaffe, 1974; Seyhun, 1986; Pope et al, 1990) To distinguish between publications of the same author published in the same year, alphabetise them according to their titles and affix the letters a, b, c and so on onto the dates. E. g. IMF and IDA (2006a), ââ¬Å"Heavily Indebted Poor Countries (HIPC) Initiative ââ¬â Statistical Update. March 21, 2006. IMF and IDA (2006b), ââ¬Å"Heavily Indebted Poor Countries (HIPC) Initiative ââ¬â List of RingFenced Countries that meet the Income and Indebtedness Criteria at end 2004. IMF and IDA (2006c), ââ¬Å"Heavily Indebted Poor Countries (HIPC) Initiative ââ¬â Issues Related to the Sunset Clause. August 16, 2006. Distinguish between different authors with the same Surname by Providing their Respective Initials Together with their Common Surname. E. g. E. O. Abuya (2010) â⬠¦ N. A. Abuya (2010). References to Institutions are done with Minimum Identification or Description. E. g. (World Bank Economic Report, 2009, p. 20) When a reference is made to a quotation found in a secondary source, it is cited in the text as follows: E. g. (McCallum and Nelson, as quoted by Muhanji, 2010, p. 560) When the date of a publication is unknown, it is cited as follows: According to Ryan and Bernard (n. d. )â⬠¦ Sources in the Reference List Arrange references alphabetically in terms of the surname of the first author. Arrange sources with the same first author but with different co-authors alphabetically according to the surname of the second author. If the same author or collection of authors has different publications, list them chronologically according to the date of publication. When referencing journal articles, the name of the journal appears in italics (or is underlined). When referencing a book, the name of the book appears in italics (or is underlined). For references from an internet source, indicate the URL and the date when the document was accessed. E. g. IMF World Bank. (2006). Applying debt sustainability framework for lowincome countries post debt relief. http://www. imf. org/external/np/pp/eng/2006/110606. pdf. (20/11/2007) 9 ? ? ? ? ? ? ? NOTES ON POPULATION AND SAMPLING ? ? ? ? When we conduct a research, we collect data from our objects of inquiry in order to solve the problem concerned. A crucial element in data collection is the research design that we use. A research design is a plan according to which we obtain research participants (subjects) and collect information from them. In a research design we specify: o The number of groups that should be used (this is necessary to decide which statistical technique to use). o Whether the groups are to be drawn randomly from the population involved and whether they should be assigned randomly to groups. What exactly should be done with them in the case of experimental research. Population and Sample ? ? ? ? ? ? The population is the study object and consists of individuals, groups, organisations, human products and events, or the conditions to which they are exposed. Population encompasses the total collection of all units of analysis about which the researcher wishes t o make specific conclusions e. g. all universities, all banks and so forth. A population is the full set of cases from which a sample is taken. The size of the population is indicated by N. A sample represents a part of the population and is denoted by n. To calculate an appropriate sample, you can use the formula: Where N is the population and Sampling is the level of precision. 1. It is divided into probability and non-probability samples 2. Examples of probability samples includesimple random samples, stratified random samples, systematic samples and cluster samples. 3. Non-probability samples include accidental/incidental samples, quota samples, purposive samples, snowball samples, self-selection samples and convenience samples. 4. In the case of probability sampling, we can determine the probability that any element or member of the population will be included in the sample. In non-probability sampling by contrast, we cannot specify this probability. 5. Advantages of probability sampling is that it enables us to indicate the probability with which sample results (e. g. sample means) deviate from the corresponding population values (e. g. population means). 6. Unlike non-probability sampling, probability sampling enables us to estimate sampling error. Nevertheless, non-probability sampling is frequently used for reasons of convenience and economy. 10 The Sampling Frame ? This is a list of units comprising a population from which a probability sample is selected. E. g. if a sample of students is selected from a studentââ¬â¢s roster, the roster is the sampling frame. Likewise, if a sample is selected from a telephone directory, the telephone directory is the sampling frame. In order to compile an appropriate sampling frame, bear in mind the following checklist: o Are the cases listed in the sampling frame relevant to your research topic? o Does the sampl ing frame include all cases i. e. is it complete? o Does the sampling frame exclude irrelevant cases, in other words, is it precise? o Can you establish and control exactly how the sample will be selected (for purchased lists). Sampling Methods Probability Sampling 1. Simple Random Sampling a. Each member of the population has an equal chance of being included in the sample and each sample of a particular size has the same probability of being chosen. b. Steps to follow when drawing a random sample include: i. Identify all the units of analysis in the sampling frameand give them cosecutive numbers e. g. 001, 002, 003, and so forth. ii. The mechanism used to choose the unit of analysis should ensure that each member has an equal chance of being selected. This can be done by means of a table of random numbers. 2. Stratified Random Sampling a. Strata are clearly recognisable, non-overlapping subpopulation that differs from one another in terms of a specific variable. Each subpopulation is called a stratum. E. g. male and female, private and public universities etc. b. In order to draw a representative stratified random sample, the following two aspects must be put in mind: i. Identify the various strata according to one or more variables. ii. Draw a random sample from each separate stratum. c. Advantages of stratified random sample include: i. In a random sample from a normal population that is stratified, e. . in terms of gender, the probability of a sample consisting of only one gender is zero. ii. Stratified random sampling requires smaller samples than simple random sampling in order to obtain valid results. 11 3. Systematic Sampling a. Suppose we need to obtain a sample of n members from a population of N elements (units of analysis) that are numbered from 1 to N. In systematic sampling, we include every element (where, is an integer i. e. a whole number). E. g. if one wants to select 10 schools from a population of 100, draw the first element at random and then select every 10th element. If the first element is 8, subsequently select 18, 28, 38, and so on. b. Systematic sampling is more practical baecause it requires less time and is cheaper than random sampling. 4. Cluster Sampling a. In large-scale surveys, it is usually difficult, if not impossible to obtain lists of all the members (units of analysis) of the population. b. In the case of cluster sampling, we first draw (stratify randomly) pre-existing heterogeneous groups called clusters c. Randomly select units of analysis from each cluster. E. g. suppose we wish to conduct a survey on primary schools in Kenya. First draw a sample from the 8 provinces. Then draw a number of districts from each province. Next you draw a number of locations from the district. Finally select a few schools within the location. d. Its disadvantage is that it requires a great deal of time and money to reach one or two individual units in a remote area. If the area is not remote, cluster sampling saves time and money compared to simple random sampling. Summary Sampling Technique Sampling Frame Required Size of Sample Needed Better with a sample size of a few hundred. Suitable for all sizes. Geographical Area Suited Relative Cost Easy to Explain to Support Workers Relatively difficult to explain. Advantages Compared to Simple Random Sampling Simple Random Accurate and easily accessible. Systematic Stratified Random Accurate, easily accessible. And not containing periodic patterns. Actual list not always needed. Accurate, easily accessible, divisible into relevant strata. Concentrated if face-to-face contact required, otherwise does not matter. Concentrated if face-to-face contact required, otherwise does not matter. High if sample size is large or if sampling frame is not computerised. Low Relatively easy to explain. Normally difference. no Suitable for all sizes. Concentrated if face-to-face contact required, otherwise does not matter. Low, provided that lists of relevant strata are available. Relatively difficult to explain. Once strata is decided, it is easy to explain. Better comparison across strata. Differential response rates may necessitate re-weighing. 12 Cluster Accurate, easily accessible, relates to relevant clusters not individual population members. As large as practicable . Dispersed if faceto-face contact is required and geographicallybased clusters are used. Low, provided that lists of relevant clusters are selected. Relatively difficult to explain until clusters are selected. Quick precision reduced. but is Non-Probability Sampling ? ? Advantage of non-probability sample is that they are less complicated and more economical (in times of time and financial expenses) than probability samples. Non-probability samples may be especially useful in pilot studies in which a preliminary form of a questionaire has to be tested. 1. Accidental/incidental Sampling o An accidental sample is the most convenient collection of members of the population (units of analysis) that are real or readily available for research purposes. E. g. people who happen to be at a certain shopping centre at a particular time or organisations that are close to the researcherââ¬â¢s home. 2. Quota Sampling o In this method, the researcher makes an effort to have the same proportions of units of analysis in important strata such as gender, age, and so on as are the population. o Quota sampling yields quite satisfactory results und er the following circumstances: ? One should know the important strata according to which the population is composed and their respective proportions with a reasonable degree of accuracy, or be able to estimate them. One should include enough cases (at least 15, but preferably more than 25) of each stratum in the sample. 3. Purposive Sampling o Researchers rely on their own experience, ingenuity and/or previous research findings to deliberately obtain units of analysis in such a manner that the sample they obtain may be regarded as being representative of the relevant population. o The problem with this kindof sampling is that different researchers may proceed in different ways to obtain a sample. o It is impossible to evaluate the extent to which samples are representative of the relevant population. . Snowball Sampling o First approach a few individuals from the relevant population 13 o These individuals then act as informants and identify other members (e. g. acquaintances or fri ends) from the same population for inclusion in the sample. o The latter may, in turn, identify a further set of relevant individuals so that the sample, like a rolling snowball, grows in size till saturated. 5. Self-Selection Sampling o This occurs when we allow a case, usually an individual, to identify their desire to take part in the research. o The researcher will do the following: ? Publicise the need for cases, either by advertising through appropriate media or by asking them to take part. ? Collect data from those who respond. o Cases that self-select often do so due to their feelings or opinions about the research question(s) or stated objective(s). 6. Convenience Sampling o Convenience or haphazard sampling involves selecting haphazardly those cases that are easiest to obtain for the sample, such as, the person interviewed at random in a shopping centre or airport or university. o The sample selection process is continued until we reach the required sample size. This technique is borne to bias and influences that are beyond control due to the fact that the cases appear in the sample because they were easy to obtain. o Subsequent generalisations are likely to be flawed at best. o Such samples serve best as pilot studies using more structural samples. Sample Style Likelihood of Sample being Representative Very low Type of Research in Which Useful When performi ng explorative research. When you do not expect to generalise findings.

Experimental research Quasi ââ¬â experimental research Non ââ¬â experimental research Qualitative research The first three constitute quantitative research. 1. Experimental Research ? This involves some form of intervention, i. e. , the participants (units of analysis) are exposed to something to which they would not have been subjected to. In the hypothesis we express the influence that the independent variable is expected to have on the dependent variable and it is this influence we measure in the experiment. ? We therefore measure the extent to which the intervention (independent variable) has changed or affected the unit of analysis (dependent variable). Measuring the dependent variable Unit of analysis Intervention ? ? ? ? ? The measurement of the dep endent variable before the intervention is called premeasurement and the measurement after the intervention is called postmeasurement. When we work with one group only, the possibility exists that considerable changes in the dependent variable could have occured without the intervention (independent variable). We therefore need a control group that is not exposed to the experimental intervention to which we can compare the group that was exposed to the intervention. A control group therefore is a group that does not receive the intervention, but serves to exercise control over the nuisance variables. A nuisance variable is any variable which is not mentioned in the research hypothesis that may influence the dependent variable. Characteristics of true experimental research a. Control over the independent variable ââ¬â This means that we may determine which levels of the variable we should use. b. Random assignment of units of analysis to groups i. Different groups are formed by means of random assignment. ii. The term random refers to the way in which the groups are assigned to the different levels of the independent variable. c. Nuisance variables (or third variables) The basic purpose of experimental research is to control nuisance variables to such an extent that the various groups differ only in terms of the levels of the independent variable in question. 5 Ways of controlling the influence of nuisance variables i. Determine the speculative effect of the nuisance variable by doing a proper literature review. In this way, nuisance variables documented in earlier research findings can be identified and controlled. ii. In few cases, it may be possible to eliminate the effect of the nuisance variable co mpletely. iii. Build nuisance variable into the design as an additional independent variable. iv. Purposely form the various groups so that they are as similar as possible in terms of all variables except the independent variable. Causality in the human behavioural sciences. A variable X may be regarded as a cause of another variable Y if each of the following three conditions are met. ? ? ? There must be a correlation between the variables. The cause must precede the effect. The third variable must be controlled. Correlation between variables ? ? ? A correlational association between X and Y exists when Y tends to appear in association with X. E. g. correlation between salary earned and productivity. The existence of a correlational effect does not mean that X causes Y. A correlation between X and Y may be the result of either a mutual relationship or a third variable Z, which may cause both X and Y. E. g. a high positive correlation between number of churches and the incidence of crime. This correlation may be attributed to a third variable, size of the population. A mutual relationship means that one variable (X) plays a role in the occurence of another variable Y which, in turn, affects the former so that there is a mutual relationship between them. From example above, the size of the population has an effect on both the number of churches and the incidence of crime. Cause must precede effect A variable or event X is considered to be a necessary cause of Y if Y cannot occur in the absence of X. E. g. motivation increases productivity. 2. Quasi-experimental Research a. True experimental research is impossible in business and administrative sciences. b. Quasi ââ¬â experimental research differs from the experimental research in that the research er cannot randomly assign subjects to the different groups. 16 There are two groups of quasi-experimental research: a. The non-equivalent control group design. Here we use two pre-existing groups as an experiment and control group, respectively. i. The threat of group differences that may already have been present prior to the start of the experimental intervention is taken into account by measuring both groups on the dependent variable prior to the experimental observation. ii. If the experimental and control groups do not differ in terms of the premeasure but do differ in terms of the postmeasure, we can ascribe the the difference in the postmeasure to the difference in intervention that they hsve received. Premeasure Experimental group Control group Intervention Postmeasure Experimental group Control group b. The interrupted time-series design i. In this, more than one measurement of the dependent variable is obtained, with equal intervals both before and after the intervention. ii. Researcher may plan the intervention or it may be an unplanned event like collapse of Lehmann brothers. 3. Non-experimental Research a. Neither random assignment nor any planned intervention occurs in nonexperimental research. b. In this type of research one or more variables, apart from the independent variable in question, could be the actual cause of observed variation in the dependent variable. E. g. , knowledge about astronomy has been obtained by non-experimental means because we cannot manipulate the stars. c. Because there is no planned intervention and the data are collected in a field situation, this design is supposed to show the greates similarity to real life. d. Research designs include: survey, non-experimental research designs involving measurements at a single time, longitudinal and opinion polls. 7 VALIDITY OF CONCLUSIONS ? ? We test research hypothesis to help us decide whether or not a specific implication inferred from a theory is tenable, or to provide an answer to a research question. The conclusion we reach about the relationship should be a true reflection of the relationship. E. g. if we wish to investigate whether attitudes have changed over time, a design that selects data at only one point in time would be inappropriate. Validity therefore refers to the extend to which an empirical measure adequately reflects the real meaning of the concept under onsideration. Internal Validity ? ? ? Internal validity describes the degree to which changes in the dependent variable are indeed due to the independent variable rather than to something else. To promote internal validity, it is necessary to eliminate all possible threats to internal validity. If we allow the threats to operate unchecked, we cannot unequivocally interpret observed changes in the dependent variable as the effect of the independent variable, and this will render the internal validity of our conclusions subject. Sources of internal invalidity/ threats to internal validity 1. History ââ¬â During the cause of the experimental research, historical events may occur that will confound the results. 2. Maturation ââ¬â People are continually growing and changing, and such changes can affect the results of the experiment. In long-term experiments, people grow older and wiser. In short-term experiments, they may grow tired, hungry, sleepy, bored and/or change in other ways that affect their behaviour in the experiment. 3. Testing ââ¬â The process of testing and retesting influences peopleââ¬â¢s behaviour, thereby confounding the experimental results. E. g. , suppose we administer a questionnaire to a group as a way of measuring their prejudice. Then we administer an experimental stimulus and re-measure their prejudice. By the time we conduct the post-test; the subjects may have become more sensitive to the issue of prejudice and will be more thoughtful in their answers. 4. Instrumentation ââ¬â The process of measurement in pretesting and post-testing brings in some issues of conceptualisation and operationalisation (operationalisation means putting a variable in measurable terms). E. g. if we used different measures of the dependent variable in the pre-test and post-test (e. g. different questionnaires about prejudice), how can we be sure they are comparable to each other. External validity ? ? ? This refers to the possibility that conclusions drawn from experimental results may be generalizable to the real world. Population validity refers to the degree to which the findings obtained from a sample may be generalised to the t otal population to which the research hypothesis applies. Biased results may be obtained if data are obtained from unrepresentative samples. 8 DATA-COLLECTION METHODS AND MEASURING INSTRUMENTS IN QUANTITATIVE RESEARCH a. Systematic observation and quantitative measurement Systematic observation means that independent observers other than ourselves should also be able to observe and report whatever we, as researchers, observe and report. b. Measurement theory ? ? ? ? If we wish to investigate the accuracy or ââ¬Å"truthâ⬠of the research hypothesis, we need to measure the dependent variables appearing in it. Measuring variables such as length or mass of things or people (subjects) does not present many problems. In human behavioural sciences, the variables we wish to measure are constructs such as liquidation, attitude towards affirmative action, entrepreneurship, helping behaviour etc. We measure these constructs indirectly by means of indicators. E. g. , a variable like socioeconomic status is a construct because there is no single indicator that perfectly encapsulates it. To measure socio-economic status we may use income, occupation, educational level, area in which one resides and so on. The nature measurement ? Measurement involves the assignment of numbers, in terms of fixed rules, to individuals (or objects) to reflect differences between them in some or other characteristic or attribute. The rules in terms of which numbers are assigned constitute an operational definition of the variable being measure e. g. length. In measurement we distinguish between different levels of measurement on the basis of the following characteristics: o Distinguishability (the number 3 is different from the number 2). o Order of rank (2 has a higher rank than 1) o Equal intervals between successively higher numbers . Levels of measurement include nominal, ordinal, interval and ratio. i. Nominal measurement ? ? ? ? In this case, the numbers we assign to individuals only serve to distinguish them in terms of the attribute being measured. In this kind of measurement, we place individuals in different, mutually exclusive and exhaustive categories in respect of such characteristics. By mutually exclusive we mean that each person belongs to one of the categories only e. g. male or female. Exhaustive implies that all individuals can be accommodated in some or other category. E. g. we could measure someoneââ¬â¢s occupation by assigning the number ? ? 19 1 to doctors, 2 to lawyers, 3 to teachers, 4 to accountants etc. The number 4 does not in any way imply a greater magnitude of the variable occupation. ii. Ordinal measurement ? ? In this case, the numbers we assign not only reflect differences among individuals but also rank order. The assumption is made that those to whom we assign higher numbers exh ibit more of the particular attribute than those to whom we assign lower numbers. E. g. suppose the order of rank of administrative staff in a company is as follows: assistant administrative officer, administrative officer, senior administrative officer. We therefore assign the numbers 1 to 3 as follows: 1 to the rank of assistant administrative officer, 2 to the rank of administrative officer and 3 to the rank of senior administrative officer. iii. Interval measurement ? An interval scale has all the characteristics of both nominal and ordinal scales, but provides additional information regarding the degree of differences between individual data items within a set or group. ? In this measurement, therefore, we use the property of equal differences between consecutively higher numbers. E. g. trust in a companyââ¬â¢s future; the question is: This company will make a profit till 2020. Absolutely 1 2 3 4 5 Not at all. iv. Ratio measurement ? ? ? ? Ratio scales represent the highest level of precision. In this, there is fixed and absolute zero point. The ratios between numbers assigned to this level of measurement can therefore be interpreted meaningfully. The advantage of using ratio scales is that any statistical analysis can be use d on data collected in this form. e. g. , Net income from sales for a small scale business. 10000 20000 30000 40000 c. Validity ? Recall that validity is the extent to which the research findings accurately represent what is really happening in the situation. ? Any given measuring instrument measures the construct intended and random measurement error (reliability). 20 ? Types of validity that relate to the independent variable include: construct validity and criterion-related validity. Construct validity ? Construct validity of the operationalisation of an independent variable is the degree to which the procedures intended to produce the independent variable of interest succeed in generating this variable rather than something else. In practice, we seldom investigate the construct validity. ? Usually we clearly describe the way in which such a variable has been operationalised and leave it to the reader to judge whether these operations have succeeded in bringing about the desired independent variable. ? The construct validity of a measuring instrument refers to the degree to which it measures the intended con struct rather than irrelevant constructs or measurement error. ? It is advisable to use more than one measure of the same construct. If this is not done, it is impossible to examine to what extend any given measuring instrument measures anything else but itself. ? An important threat to the construct validity of questionnaire measurements of personality, interests, and attitudes lies in measurement reactivity. ? The response sets of faking and social desirability and the response style of acquiescence imply that individualsââ¬â¢ responses are not true reflections of their personalities, interests, and attitudes. ? Faking means that participants deliberately distort their responses in order to create a desired impression. E. g. question like do you easily lose your temper? A respondent will answer negatively because he wishes o create a good impression. ? In social desirability, subjects deliberately or inadvertently provide the responses that they believe to be socially accepted. E. g. a question like do you like everybody you know? Respondents may answer positively because they believe that it would be sociall y unacceptable not to like some people. ? Acquiescence refers to the phenomenon where research participants tend to consistently answer ââ¬Å"yesâ⬠(to no/yes items) or ââ¬Å"trueâ⬠(rather than false), irrespective of the content of the question. E. g. an interviewee may answer ââ¬Å"yesâ⬠to both of the following statements: I prefer to spend a night out in town with friends instead of staying at home reading a book. I prefer a quiet night at home reading a book instead of partying with friends. Answering yes to both questions is contradictory. Criterion-Related Validity ? This refers to the degree to which diagnostic and selection measurement/tests correctly predict the relevant criterion. 21 ? ? The relevant criterion refers to the variable that is to be diagnosed or on which success is to be predicted respectively. E. g. he validity of university exams is shown in their ability to predict studentsââ¬â¢ success in university. d. Reliability ? ? ? This is concerned with the findings of the research and relates to the credibility of the findings. In determining whether our findings are reliable, we need to ask the following question: will the evidence and conclusions stand up to the closest scrutiny? It stands to re ason that if we measure a construct (e. g. small business success) by means of a particular instrument (e. g. taxable profit), comparable measurements should be obtained for the same individual/objects irrespective of, e. . , when the instrument is administered, which particular version of it is used, and who is applying or administering it. Reliability therefore refers to the extent to which the obtained scores may be generalised to different measuring occasions, measurement/test forms and measurement/test administrators. Generalisation refers to the consistency of the ranking (of scores) that we assign to the individuals or objects, irrespective of when the measuring instrument was applied, which form it was used, and by whom it was administered. Scores that are assigned to individuals should therefore be consistent irrespective of the time of measurement, the test used, and the person administering the test. ? ? ? Estimating reliability ? If a research finding can be repeated, it is reliable. In other words, if anyone else were to repeat the research, they should be able to obtain the same results as those obtained originally. E. g. , if we find that a group of workers who attended a training course doubled their previous productivity levels, and another researcher obtained similar results, the measurements are reliable. Repeating a research study in order to establish reliability is known as replication. Test-retest reliability ? To determine test-retest reliability of a measuring instrument, we should administer it on at least two occasions to the same large, representative sample from the population for which the instrument is intended. We then correlate the two sets of scores obtained in this way and calculate a correlation coefficient for the two sets of data. This coefficient is an index of reliability. 22 ? ? ? ? ? ? ? ? The time interval between the two administrations should not be too long to prevent real and permanent changes from taking place in the attribute being measured. At the same time, it should not be too short so that participants may remember the responses given on the first administration. A disadvantage of this method is that it is often difficult to persuade respondents to answer questions a second time. Furthermore, if they do answer the questions a second time, they may think more deeply about the questions on the second occasion and provide different answers. Parallel-forms reliability ? Parallel-form reliability of a measurement test is determined by using interchangeable versions of a measurement/test that have been compiled to measure the same construct equally well but by means of different content. The different versions are administered to the same representative sample and the obtained scores are correlated. Parallel-forms reliability deals with the generalisability over parallel measurement/test forms. ? ? Internal consistency ? ? A high internal consistency implies a high degree of generalisability across the items within the measurement test. In other words, if a person performs well on a few items in such a measurement/test, the chances are good that he/she will fare equally well on the remaining items in the measurement/test. Every item is correlated with every other item across the entire sample and the average inter-item correlation is taken as the index of reliability. To determine the reliability of a measuring instrument by using the internal consistency method, we administer the measurement/test only once to a large representative sample. It is important to note that the longer a measurement/test is, in other words, the more appropriate content it covers, the higher its internal consistency should be. ? ? ? Split-halves reliability ? ? This is calculated by correlating the scores on one half of the test with the scores for the other half of the test. The test is therefore divided into equal halves which are the correlated in terms of the scores for each half. 23 ? The correlation coefficient for the two halves is then calculated and indicates the reliability of the test. In conclusion, a good measurement technique should be both valid (measuring what it is intended to measure) and reliable (yielding a given measurement dependability). Reliable but not valid Valid and not reliable Valid and reliable Pilot Studies in the development of a questionnaire ? ? When a new measuring instrument is developed, it is useful to ââ¬Å"test it outâ⬠before administering it to the actual sample. The process of ââ¬Å"testing outâ⬠is done by means of a pilot study which entails administering the instrument to a limited number of subjects from the same population as that for which the eventual project is intended. The pilot study is therefore a ââ¬Å"dress rehearsalâ⬠for which the eventual project is intended. ? Purpose of a pilot study ? To detect possible flaws in the measurement procedures such as ambiguous instructions, adequate time limits as well as in the operationalisation of the independent variables. E. g. , you may have to use a range of income instead of a fixed numerical value. To identify unclear or ambiguously formulated items. In such a pilot study, the actual questions are put to the respondents, and they are then asked to indicate how they have interpreted the formulated questions. An opportunity for researchers and assistants to notice non-verbal behaviour on the part of the participants that may possibly signify discomfort or embarrassment about the content or wording of the questions. NB: it is virtually mandatory to test survey questionnaires on a small group of individuals who are representative of the populations for which they are intended. If the instrument is extensively revised in reaction to the results of the pilot study, the revised instrument should be subjected to a new round of testing. ? ? 24 Measuring instruments ? ? ? Sources of data include primary data and secondary data. Primary data are original data collected by the researcher for the purposes of his/her own study at hand. Secondary data are information collected by individual or agencies and institutions other than the researcher him ââ¬â or herself. Types of measuring instruments 1. Survey questionnaires, standardised measuring instruments and attitude scales. These do not involve direct observations of the behaviour of subjects but, instead, individualsââ¬â¢ reports of their behaviour. These measuring instruments are therefore susceptible to measurement reactivity (like withholding of co-operation to deliberate deception). 2. Rating scales which require raters to assess the behaviour of participants. Bias on the part of the raters can invalidate such information. 3. Indicators such as the inflation rate, CPI, retail sales, registered unemployed, FDI, etc. These are compiled and calculated by people such as government officers. The information (figures) is published in reports, manuals, databases, etc. Unobtrusive measurement ? ? ? This occurs when a subjectââ¬â¢s behaviour is observed and the participant is unaware that measurement is taking place. The researcher can observe through either one-way mirror, hidden cameras or behave like a detective. The problem of measurement reactivity is completely eliminated. Group contacts Advantages of collecting data from groups of people 1. Captive audiences such as students or prisoners, the elderly in a home for the aged etc are available to work with. This procedure then corresponds to the administration of a group measurement/test. 2. Since a single person (with possibly a few assistants) is required to provide the instructions in one room or hall, the cost per questionnaire (in the case of surveys) is much lower than that of a personal interview. 3. The researcher is in full control of the completion of the questionnaires. The session is arranged with the permission of the appropriate authorities (e. g. schools, university etc) so that no respondent has an excuse for not completing the questionnaire. Response rate is close to 100%. 4. Since the researcher and his/her assistants are present, queries about the completion of survey questionnaires may be answered immediately. 25 5. The group contact way of administering questionnaires corresponds to the personal interview as far as the presence of the interviewer is concerned, but it allows for the same degree of anonymity as the typical postal survey. ? ? The disadvantage of this method is that it is limited to a few populations. Categories of group contacts include: survey questionnaires and postal dispatch, standardised tests, attitude scales, and rating scales and situational tests. Survey questionnaire and postal dispatch ? Survey questionnaires are used to obtain the following types of information from respondents: ? Biographical details e. g. age, educational qualifications, income etc. ? Typical behaviour e. g. the television programme they favour. ? Opinion, beliefs and convictions about any topic or issue e. g. the present political state. ? Attitudes e. g. towards affirmative action. An example of a survey questionnaire is: The leadership in my organisation at the present time is: Hardworking ? ? 1 2 3 4 5 Lazy ? ? ? ? ? Attitudes should preferably be assessed by means of attitude scales rather than survey questionnaires. Whereas attitude scales are completed by the respondents typically under the supervision of research staff, we can obtain information about biographical particulars, typical behaviour, opinions, and beliefs in persons, by telephone, mail or email. When compiling the questionnaire, we should take the eyesight and the literacy level of the intended respondents into consideration. Not only should the intended respondent be able to read and write, but they should also be able to follow instructions. Ignorant respondents may find complicated filter questions, which involves different routes for responses confusing. The purpose of filter questions is to determine whether her respondents should answer all subsequent questions or whether they can omit some of them. Unlike personal interview and telephonic interviews, the respondents cannot fall back on anybody else but themselves since the interviewer is not available to direct them around irrelevant questions. Conducting a typical postal or mail survey involves the following two stages: ? We first assemble the questions asking for information about biographical particulars, typical behaviour or opinion and beliefs that we want to put to the respondents in a structured questionnaire. 26 ? We then post the questionnaire to respondents with the request that they be completed and returned by mail or fax. Advantages of postal surveys 1. Cost and ease of application A postal survey is the least expensive of all survey methods. Irrespective of how far and wide the respondents are scattered across the country, they can all be reached by means of a relatively low postal cost. 2. Anonymity Postal survey provides the greatest possibility of anonymity, i. e. , no name or identification is given. Disadvantages 1. Control over responding The researcher has least control over the conditions under which postal questionnaires are completed. The chances are great that some questions may be omitted or not be respondent to in the order presented, or someone else may complete the questions. 2. Response rate Researchers lack control over the completion of the questionnaires. It may result not only in poorly completed questionnaires, but also a poor response rate. Postal survey response rates frequently fall below 50% of the target population. To improve the response rate of postal surveys, the questionnaire may be: ? ? ? ? Delivered in person to the respondentsââ¬â¢ addresses with a request that they be posted back on completion. Posted and collected personally. Both delivered and collected personally. Questionnaires can be followed up by letters and postcards reminding the respondents to complete and return them. Standardised tests ? A standardised test is a collection of tasks in which the content, the administration and the scoring of the obtained responses are the same, irrespective of who is administering it and by whom it is scored. Standardised tests take the form of individual test and group tests. Individual test may only be administered individually, in other words, a test administrator can administer it to only one testee at a time. Group test may be administered to more than one individual simultaneously in one session. Types of tests include aptitude tests (which include intelligence tests), academic achievement tests, personality tests, and interest tests. 27 ? ? ? ? Attitude scales ? ? An attitude is a disposition towards a particular issue, the so called attitudinal object. Attitudinal object may refer to: o A political, economical, or social issue (e. g. , tax on wealth creation, the death penalty etc). o A custom (e. g. , female genital mutilation). o A group (e. g. , UASU, KNUT) The following is an example of an attitude scale: ? An attitudinal scale to test the efficiency of a bus company (e. g. Easy Coach) Strongly agree 1 1 1 1 Agree 2 2 2 2 Agree in some cases 3 3 3 3 Do not agree 4 4 4 4 Strongly disagree 5 5 5 5 Buses are on time Drivers are reckless Fares are too high Service is regular ? Note: researchers as a rule have to compile their own attitude scales to measure the attitudes relevant to their research. Types of attitude scales 1. 2. 3. 4. Likert scale or summated scale Semantic differential The Guttman scale The Thurstone scale These attitude scales are based on different assumptions about the relationship between individuals, their attitudes, and their responses to the items. The summated or Likert scale ? ? ? This is the most popular type of scale in social sciences. Its popularity stems from the fact that it is easier to compile than any of the other attitude scales (more particularly, Guttman and Thurstone). In Likert scale, subjects have to indicate the degree to which they agree or disagree with its content on, for instance, a five-point scale (e. g. , strongly differ, differ, undecided, agree, strongly agree).
