Optimality Theory - Essay Example Joseph Paul Stemberger And Barbara Handford Bernhardt "The Emergence of Faithfulness" http://www.linguistics.ubc.ca/People/Stemberger/S_B_1999.pdf. Stemberger & Bernhardt, 1999 asserted "The basis of OT is the use of constraints rather than rules. Rules within language are procedures that construct representations and alter them in particular ways. Constraints, in contrast, are limitations on what is possible in a system. Constraints can also lead to the alteration of a representation such that information is lost or added. From a cognitive-psychological perspective, however, the mechanisms are quite different". (Stemberger & Bernhardt, 1999, pp. 417-446) If we conceptualize phonology as part of the process for producing and understanding language, the phonological properties of language must result from the fact that it is an extremely practiced behavior linked with the vocal tract of human beings. To move away from the more theoretical views of phonology, it is perhaps helpful to compare speaking to other moderately complex but repetitive neuron-motor activities, such as playing the piano. While a person learns to play the piano, he or she learns not just to strike notes, but to strike notes in sequence. Every piece of music has its own sequence of notes that should be learned. Practice is essential; the motor patterns that guide to the fluent, striking of longer and longer sequences of notes should be automated for a piece to begin to sound like music. With practice, the transitions linking the notes become more fluent, and the speed of execution mechanically increases. In order to maintain the correct rhythm and tempo, the player should at times hold back and not play every note as fast as doable. Several analogies with the acquisition and use of phonology are observable. Children learn phonological sequences as parts of words, never separately of words. Articulatory routines that are by now mastered are called forth for the production of new words, leading to a propensity of children to expand their vocabulary by obtaining words that are phonologically comparable to those they already know (Ferguson and Farwell 1975, Lindblom 1992). This propensity leads to the structuring of the phonological sequences across words and the restrictive of the potentially massive phonetic inventory. Put another way, the repetition of gestures and sequences across words permits relations of identity and similarity to expand in stretches of speech, giving rise to segment, syllable, and foot-sized units. Through practice, speakers become more fluent in stringing words together and this fluency and automation is typified by the smoothing of transitions and overlapping of movements forced by the need to retain information value. Several repeated sequences become highly automated and abridged in form. At the same time, speakers should be able to access and recruit sequences into new combinations to state their thoughts and intentions. With practice, t

Standard costing and the relationship it may have with other Essay

Standard costing and the relationship it may have with other management accounting development - Essay Example Standard costs are pre-determined or forecast estimates of cost to manufacture a single unit, or a number of units of a product, during a specific immediate future period. They are usually the planned costs of the products under current and anticipated conditions, but sometimes they are the costs under normal or ideal conditions of efficiency, based on an assumed given output, and having regard to current conditions. They are revised to conform to super-normal or sub-normal conditions, but ore practically to allow for persisting alterations in the prices of material and labour. Therefore, a standard cost can be defined as â€Å"A pre-determined cost calculated with respect to a prescribed set of working conditions, correlating technical specifications and scientific measurements of materials and labour to the price and wage rates expected to apply during the period to which the standard cost is expected to relate, with an addition of an appropriate share of budgeted overhead. Its main objective is to provide bases of control through variance accounting for the valuation of stocks and work-in-progress and in exceptional cases for fixing selling prices.† The use of standards facilitates many business functions. Standards are very useful in the monitoring and controlling of business activities in general. The need for standard costs arises as a result of the benefits it provides for a business, such as Cost control does not merely refer to minimization of costs. Cost control means identifying costs with their benefits and ensuring that the costs are justified, given the benefits that are derived. Standard costs provide a very useful framework for cost control. The great value of standards in cost control is that they provide the ability to compare actual costs with desired costs on a timely basis. Timely reporting of difference i.e. monthly, weekly, daily or for each work shift etc, between actual and standard costs allows managers to take
