capitalism w/out racism Linguistics In the early 20th century Ferdinand de Saussure distinguished between the notions of langue and parole in his formulation of structural linguistics. According to him, parole is the specific utterance of speech, whereas langue refers to an abstract phenomenon that theoretically defines the principles and system of rules that govern a language.[9] This distinction resembles the one made by Noam Chomsky between competence and performance, where competence is individual's ideal knowledge of a language, while performance is the specific way in which it is used.[10] In classical Indian philosophy of language, the Sanskrit philosophers like Patanjali and Katyayana had distinguished between sphota (light) and dhvani (sound). In the late 20th century, French philosopher Jacques Derrida distinguished between the notions of speech and writing.[11] Nomenclature[edit] Variation and Universality[edit] Lexicon[edit] The lexicon is a catalogue of words and terms that are stored in a speaker's mind.
Utility Economic definitions[edit] In economics, utility is a representation of preferences over some set of goods and services. Preferences have a (continuous) utility representation so long as they are transitive, complete, and continuous. Utility is usually applied by economists in such constructs as the indifference curve, which plot the combination of commodities that an individual or a society would accept to maintain a given level of satisfaction. In finance, utility is applied to generate an individual's price for an asset called the indifference price. Quantifying utility[edit] It was recognized that utility could not be measured or observed directly, so instead economists devised a way to infer underlying relative utilities from observed choice. Utility is taken to be correlative to Desire or Want. Cardinal and ordinal utility[edit] Economists distinguish between cardinal utility and ordinal utility. Utility functions of both sorts assign a ranking to members of a choice set. implies .
Usability Usability is the ease of use and learnability of a human-made object. The object of use can be a software application, website, book, tool, machine, process, or anything a human interacts with. A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers, technical writers, marketing personnel, and others. It is widely used in consumer electronics, communication, and knowledge transfer objects (such as a cookbook, a document or online help) and mechanical objects such as a door handle or a hammer. Usability includes methods of measuring usability, such as needs analysis[1] and the study of the principles behind an object's perceived efficiency or elegance. In human-computer interaction and computer science, usability studies the elegance and clarity with which the interaction with a computer program or a web site (web usability) is designed. Introduction[edit] Definition[edit] Usability is a non-functional requirement.
History of economic thought Study of the development of economic thought The history of economic thought is the study of the philosophies of the different thinkers and theories in the subjects that later became political economy and economics, from the ancient world to the present day in the 21st century. This field encompasses many disparate schools of economic thought. Ancient Greek writers such as the philosopher Aristotle examined ideas about the art of wealth acquisition, and questioned whether property is best left in private or public hands. In the Middle Ages, Thomas Aquinas argued that it was a moral obligation of businesses to sell goods at a just price.[1] In the Western world, economics was not a separate discipline, but part of philosophy until the 18th–19th century Industrial Revolution and the 19th century Great Divergence, which accelerated economic growth.[2] Ancient economic thought (before 500 AD)[edit] Ancient Greece[edit] China[edit] India[edit] Greco-Roman world[edit] Thomas Aquinas[edit] Joseph E.

Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and biological processes that underlie cognitive functions and behaviors. While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in many different spheres of human activity.

Consequentialism Consequentialism is usually distinguished from deontological ethics (or deontology), in that deontology derives the rightness or wrongness of one's conduct from the character of the behaviour itself rather than the outcomes of the conduct. It is also distinguished from virtue ethics, which focuses on the character of the agent rather than on the nature or consequences of the act (or omission) itself, and pragmatic ethics which treats morality like science: advancing socially over the course of many lifetimes, such that any moral criterion is subject to revision. Consequentialist theories differ in how they define moral goods. Some argue that consequentialist and deontological theories are not necessarily mutually exclusive. Consequentialist philosophies[edit] State consequentialism[edit] Mozi supported a communitarian form of consequentialism, rather than individual pleasure or pain.[4] Utilitarianism[edit] Ethical egoism[edit] Ethical altruism[edit] Rule consequentialism[edit]
Ergonomics Human factors and ergonomics (HF&E), also known as comfort design, functional design, and user-friendly systems,[1] is the practice of designing products, systems or processes to take proper account of the interaction between them and the people who use them. The field has seen contributions from numerous disciplines, such as psychology, engineering, biomechanics, industrial design, physiology and anthropometry. In essence, it is the study of designing equipment and devices that fit the human body and its cognitive abilities. The two terms "human factors" and "ergonomics" are essentially synonymous.[2][3][4] The International Ergonomics Association defines ergonomics or human factors as follows:[5] HF&E is employed to fulfill the goals of occupational health and safety and productivity. Human factors and ergonomics is concerned with the "fit" between the user, equipment and their environments. Etymology[edit] Domains of specialization[edit] New terms are being generated all the time. Books
Eco Notes Voluntary sector The voluntary sector or community sector (also non-profit sector or "not-for-profit" sector) is the sphere of social activity undertaken by organizations that are not for profit[1] and non-governmental. This sector is also called the third sector, in reference to the public sector and the private sector. Civic sector or social sector are other terms for the sector, emphasizing its relationship to civil society. Given the diversity of organizations that comprise the sector, Peter Frumkin prefers "non-profit and voluntary sector".[2] Country-specific[edit] France[edit] Discourse on the "third sector" began in the 1970s in France as a result of the crisis in the welfare state.[3] United Kingdom[edit] The Cabinet Office of the British government until 2010 had an Office of the Third Sector that defined the "third sector" as "the place between State and (the) private sector India[edit] Israel[edit] Significance to society and the economy[edit] Sub-sectors[edit] Concerns[edit] See also[edit] Examples:
