...Porter's five competitive forces analysis is a framework for industry analysis and enterprise strategy of the development in 1979 by Harvard business school of Michael porter. Upon industrial organization economics to five forces that determine the competition intensity and attractiveness of a market. In this respect the attraction, an unattractive industry is in one of the combination of these five forces role to drive down overall profitability. A very small industry will be a close to "perfect competition", which to all of the profits of the business was driven to normal profit. They consist of those forces close to the company that affect the ability to service and make the profit. A change in any of the forces normally requires a business unit to reassess the marketplace given the overall change in industry information. The company is able to apply their own core competitiveness, business model or network to achieve a profit above the industry average. Bargaining power of suppliers The suppliers mainly through its raise prices of input factors and reduce the capacity of the unit value of quality to affect the profitability of existing enterprises in the industry and the competitiveness of their products. The strength of the suppliers forces depends mainly on what they provide to the buyer is input factors constitute a large proportion of the total cost of the purchaser product, when the value of the input factors provided by the supplier, the buyer of the production...

...Charles Barkely Smiley 2015 Anthropology 106 04 October 2015 Unit 5 Assignment Vessel 1: 1. This vessel originates from the Tusayan Black-on-White traditions. 2. I believe this vessel is more closely associated with the Black Mesa Black-on-White potter dating back to about 1000 AD 3. This vessel was difficult to identify for me particularly but I made my assumptions on the basis of the design technique, which includes thicker lines and also the vessel shape which seems as though it was col built. The thicker lines were an indication that it is a newer form as opposed to those with thinner lines. 4. The Black-on-White traditions encompasses 800-1200 AD but this particular piece is specific to around 1000 AD Vessel 2: 1. Originates from the grand tradition of the Jomon. 2. The time period would most accurately be described as around 16,000 years ago. 3. The vessel is beautifully made, and it seems as though the applique technology was applied judging by the intricate designs applied to the top of the piece. The decoration is elaborate and more heavily focused towards the top. The vessel itself could have been used by the coiling technique which would mean the original vessel was thin however, it is possible it was made denser after the decorations were added. 4. This ceramic tradition dates back to about 16,000 years ago in Japan. The culture itself was composed of a population who were forager-fisher-hunters, who farmed little and...

...Difference between contract law, tort law, and common law. * Contract law refers to written agreements and oral promises * General principles of contract law determine whether an employer-employee relationship exists and what remedies apply to breach of the employment agreement. * A contract has three elements, offer, acceptance and consideration. * Tort law refers to any wrongdoing * A tort is a wrong for which there is legal remedy. * Tort law is a branch of civil law and covers wrong and damages that one person or company cause to another independent of any contractual relationship between them. * Tort can be deliberate or negligent. In order to establish negligent tort, the plaintiff must prove 1 that the defendant owed the plaintiff duty of care, 2 the duty of care was breached, and 3 the plaintiff suffered foreseeable damages as a result. * Common law is the legal system used predominantly in Canada – it derives from England * It is precedent-based law, where we follow past court decisions and existing laws (known as statutes) * Laws must be followed by all citizens, governments, and courts * Within each law is a REGULATION, which are enforcement tools of the law * E.g. Employment Standards Code is a law in AB, but its regulations actually enforce the law (carry it out) * For employment matters, contract law is important because there is an EMPLOYMENT CONTRACT between an employer and employee. * For employment...

Саньярова Н.С Выполнил: Ст.группы МЭПП-13 Ускембаев А.Б. Алматы 2013 Задание 1. Поделитесь знаниями на тему «Психология в современном мире». Сейчас, когда написано уже много учебников и справочников по социальной психологии, составлено большое число хрестоматий, мы с удивлением обнаруживаем, что эта удивительная наука сама стала проблемой не только для других (имеется в виду огромная прикладная сфера), но и для самой себя. Оглядываясь назад (подробный исторический очерк вы найдете в следующем разделе), мы не перестаем удивляться тому, на какой плодородной междисциплинарной почве она возникла. Как наука, по сути, она стала оформляться почти одновременно с психологией вообще. Однако зарождение ее, подобно жизне лотоса, охватывало все основные стихии. Она родилась на пересечении философии, языкознания, социологии, психофизиологии и даже теологии (если "дух народа" понимать не легкомысленно метафорически, а по существу). У ее колыбели стояли такие великие мыслители, как В. фон Гумбольдт и В. Вундт, А.А. Потебня и Н.К. Михайловский и др. Мы знаем десятки, если не сотни великих умов, прикоснувшихся к проблеме социально- психологической реальности. При этом весьма знаменательно то, что большинство историков социальной психологии источник или корень социально-психологической мысли...
