History of communication studies Various aspects of communication have been the subject of study since ancient times, and the approach eventually developed into the academic discipline known today as communication studies. Pre-20th century Communication has existed since the beginning of human beings, but it was not until the 20th century that people began to study the process. As communication technologies developed, so did the serious study of communication. When World War I ended, the interest in studying communication intensified.
Supply and Demand The price P of a product is determined by a balance between production at each price (supply S) and the desires of those with purchasing power at each price (demand D). The diagram shows a positive shift in demand from D1 to D2, resulting in an increase in price (P) and quantity sold (Q) of the product. If demand increases (demand curve shifts to the right) and supply remains unchanged, a shortage occurs, leading to a higher equilibrium price.If demand decreases (demand curve shifts to the left) and supply remains unchanged, a surplus occurs, leading to a lower equilibrium price.If demand remains unchanged and supply increases (supply curve shifts to the right), a surplus occurs, leading to a lower equilibrium price.If demand remains unchanged and supply decreases (supply curve shifts to the left), a shortage occurs, leading to a higher equilibrium price.

Center for Economic Research and Forecasting This article was written by Bill Watkins and previously published on New Geography on November 12, 2013. Jerry Brown is supposed to be a different kind of politician: well informed, smart, slick, and skilled. While he has had some missteps, he’s always bounced back. His savvy smarts have allowed him to have a fantastically successful career while generally avoiding the egregious dishonesty that characterizes so many political practitioners. So, I was shocked to read that he said that California’s poverty is a result of the State’s booming economy. Here’s part of the Sacramento Bee report:
Microeconomics This is in contrast to macroeconomics, which involves the "sum total of economic activity, dealing with the issues of growth, inflation, and unemployment." Microeconomics also deals with the effects of national economic policies (such as changing taxation levels) on the aforementioned aspects of the economy. Particularly in the wake of the Lucas critique, much of modern macroeconomic theory has been built upon 'microfoundations'—i.e. based upon basic assumptions about micro-level behavior. Assumptions and definitions Microeconomic theory progresses by defining a competitive budget set which is a subset of the consumption set.
Psychology Psychology is an academic and applied discipline that involves the scientific study of mental functions and behaviors. Psychology has the immediate goal of understanding individuals and groups by both establishing general principles and researching specific cases, and by many accounts it ultimately aims to benefit society. In this field, a professional practitioner or researcher is called a psychologist and can be classified as a social, behavioral, or cognitive scientist. 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.

Anthropology Anthropology /ænθrɵˈpɒlədʒi/ is the study of humankind, past and present, that draws and builds upon knowledge from social and biological sciences, as well as the humanities and the natural sciences. Since the work of Franz Boas and Bronisław Malinowski in the late 19th and early 20th centuries, anthropology in Great Britain and the US has been distinguished from ethnology and from other social sciences by its emphasis on cross-cultural comparisons, long-term in-depth examination of context, and the importance it places on participant-observation or experiential immersion in the area of research. In those European countries that did not have overseas colonies, where ethnology (a term coined and defined by Adam F. Origin of the term The term anthropology originates from the Greek anthrōpos (ἄνθρωπος), "human being" (understood to mean humankind or humanity), and -λογία -logia, "study." Fields
Production–possibility frontier Indicators Efficiency An example PPF with illustrative points marked The PPC shows left to right downward position. A PPF(production possibility frontier) or PPC typically takes the form of the curve on the right. An economy that is operating on the PPF is said to be efficient, meaning that it would be impossible to produce more of one good without decreasing production of the other good. A parable about how one nation came to financial ruin. - By Char In the early 1700s, Europeans discovered in the Pacific Ocean a large, unpopulated island with a temperate climate, rich in all nature's bounty except coal, oil, and natural gas. Reflecting its lack of civilization, they named this island "Basicland." The Europeans rapidly repopulated Basicland, creating a new nation. They installed a system of government like that of the early United States. There was much encouragement of trade, and no internal tariff or other impediment to such trade. Property rights were greatly respected and strongly enforced.

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. 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. 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. Nomenclature
Education School children sitting in the shade of an orchard in Bamozai, near Gardez, Paktya Province, Afghanistan A right to education has been recognized by some governments. At the global level, Article 13 of the United Nations' 1966 International Covenant on Economic, Social and Cultural Rights recognizes the right of everyone to an education. Although education is compulsory in most places up to a certain age, attendance at school often isn't, and a minority of parents choose home-schooling, e-learning or similar for their children. Etymology Etymologically, the word "education" is derived from the Latin ēducātiō ("A breeding, a bringing up, a rearing") from ēdūcō ("I educate, I train") which is related to the homonym ēdūcō ("I lead forth, I take out; I raise up, I erect") from ē- ("from, out of") and dūcō ("I lead, I conduct"). Education can take place in formal or informal educational settings.
