classical conditioning Essay -- essays research papers

When ever the bell rings in any school in any nationyou are guaranteed to see students and teachers file into the hallway.   This automatic response comes from somethingthat has been around for a long time called classical conditioning. Classicalconditioning was discovered and researched by Ivan Pavlov, a Russianphysiologist.   His famous experimentwith his dog is known to nearly everyone who has had a middle school or highereducation.   He fed his dog in a pattern,every time he fed his dog he rang a bell.  Eventually the dog associated the bell with food and would begin tosalivate just on hearing the bell.   Thatis the original experiment proving classical conditioning.   What is aconditioned stimulus?   â€Å"A neutralstimulus that, after repeated pairings with an unconditioned stimulus, becomesassociated with it and elicits a conditioned response.† (World of Psychologypg167)  Ã‚   In English it is something thatis used to train someone or something through repetition.   Pavlov made use of this in his experiment toshow classical conditioning.   Where asan unconditioned stimulus is something that is unlearned but is just respondedto out of instinct.   Pavlov’s dog, for examplehad one unconditioned stimulus and one conditioned stimulus.   Both the conditioned and unconditionedstimuli were to an unconditioned response, the dog salivating.   The unconditioned stimulus was the dog foodthat started the dog salivating.   The conditionedstimulus or new stimulus was the bell being rung every time the dog was fed.After awhile the unconditioned stimulus wasn’t even needed, because the dog wasnow conditioned to respond to the bell and salivate whenever he heard thebell.   Things like this happened all thetime, for example; when I put on running shoes and running clothes my dog willbecome extremely hyper because she knows we are going outside and she will getto run around. Probably thestrongest application of classical conditioning is emotions.   Human emotions are condition extremelyeasily to things that provoke strong reaction, things such as Adolf Hitler, theIRS, the American Flag and chemistry class because of their associations withour emotions.   If something like thatprovoked a strong emotion before in your life when brought up in conversationthe strong emotion that was conditioned comes up also.   For example when a person meets someone withthe same name as someone they previously lik... ...   He thenwondered would the dog still salivate if he attached the device to the dogspelvis, then hind paw, then shoulder, then foreleg and finally the frontpaw.   He discovered that the farther hegot from the rear thigh, or the original conditioning, the less of a salivatingresponse.   Other examples of this arethings such as someone who was attacked by a dog when he or she was young andtherefore grew up hating and fearing all dogs.   On the other sideof generalization there must be discrimination.   Pavlov decided he didn’t want his dogs to salivate to any othertones but â€Å"C.†Ã‚   This was not very hard all that was need was to cause extinction in any other type of tone.   The â€Å"C† tone was reinforced by continuouslygiving food after the tone was rung.   On the other hand whenever any other tone was sounded it was not reinforced by food.   Thus the dog became more conditioned to â€Å"C† and the conditioned responses for the other tones becameextinct. Classicalconditioning has and will continue to be around forever.   It is part of human nature and many peopletake advantage of it daily.   It can beused to dispel fears or as training for a job, it doesn’t matter what it is for it will just be there.

Theoretical and practical capacity levels are driven by supply-side concepts, i. e. , â€Å"how much can produce? † Normal and master-budget capacity levels are driven by demand-side concepts, i. e. , â€Å"how much can we sell? † (or â€Å"how much should we produce? †) 2. In order to incorporate fixed manufacturing costs into unit product costs, fixed manufacturing costs have to be unitized for inventory costing.Absorption costing is the method used for tax reporting and for financial reporting using generally accepted accounting principles. The choice of a denominator level becomes relevant under absorption costing because fixed costs are accounted for along with variable costs at the individual product level. Variable and throughput costing account for fixed costs as a lump sum, expensed in the period incurred. 3. The variances that arise from use of the theoretical or practical level concepts will signal that there is a divergence between the supply of capacity and the demand for capacity.This is useful input to managers. As a general rule, however, it is important not to place undue reliance on the production volume variance as a measure of the economic costs of unused capacity. 4. Under a cost-based pricing system, the choice of a master-budget level denominator will lead to high prices when demand is low (more fixed costs allocated to the individual product level), further eroding demand; conversely it will lead to low prices when demand is high, forgoing profits.This has been referred to as the downward demand spiral—the continuing reduction in demand that occurs when the prices of competitors are not met and demand drops, resulting in even higher unit costs and even more reluctance to meet the prices of competitors. The positive aspect of the master-budget denominator level is that it indicates the price at which all costs per unit would be recovered to enable the company to make a profit. Master-budget denominator level is also a good benchmark against which to evaluate performance. -40(20 min. )Cost allocation, downward demand spiral. 1. = = Budgeted denominator level=2,920,000 meals WHM is using budgeted usage as its denominator level for calculating the budgeted fixed costs per meal in 2007. 2. Alternative denominator levels include: a. Capacity available. The data in the problem note that the facility can serve 3,650,000 meals a year. With this denominator level, there will be budgeted unused capacity, which could be recorded as a separate line in the cost report for the Santa Monica facility. . Budgeted usage of capacity. With the 2007 budgeted usage of 2,920,000 meals, the fixed costs charge is $1. 80 per meal. The marketplace is signalling that WHM’s own central food-catering facility is not providing value for the costs charged. If Cheung decides to raise prices to recover fixed costs from a declining demand base, he will likely encounter the downward demand spiral: Budgeted Denominator(1)| Variable Cost per Meal(2)| Fixed Cost per Meal$5,256,000 ? 1)(3)| Total Cost per Meal(4)| 3,650,000| $4. 56| $1. 44| $6. 00| 2,920,000| 4. 56| 1. 80| 6. 36| 2,550,000| 4. 56| 2. 06| 6. 62| 2,000,000| 4. 56| 2. 63| 7. 19| Cheung might adopt a contribution margin approach, which means viewing the $4. 56 variable cost as the only per-unit cost and the $5,256,000 as a fixed cost. Alternatively, Cheung could use practical capacity to cost the meals and work to reduce costs of unused capa city. 3. Three factors managers should consider in pricing decisions: a. Customers.Cheung is facing customers who are dissatisfied with both the cost and the quality of the meal service. Three of the 10 hospitals have already elected to use an outside canteen service. b. Competitors. For the three hospitals terminating use of the Santa Monica facility, at least one competitor is more cost-effective. The seven remaining hospitals likely will be very interested in how this competitor performs at the three hospitals. c. Costs. Jenkins should consider ways to reduce both the variable costs per meal and the fixed costs.

Feminism A Controversial Aspect Of Feminism - 1833 Words

Feminism is Fashionable The conversation about feminism today is often followed with an eye-roll, uncomfortable sigh, and quick subject change. Feminism isn’t an issue people want to debate about because of the radical views of some feminists, but this doesn’t mean we can’t recognize it.
