Paucity
In economics, scarcity "refers to the basic fact of life that there exists only a finite amount of human and nonhuman resources which the best technical knowledge is capable of using to produce only limited maximum amounts of each economic good."Samuelson, P. Anthony., Samuelson, W. (1980). Economics. 11th ed. / New York: McGraw-Hill. If the conditions of scarcity didn't exist and an "infinite amount of every good could be produced or human wants fully satisfied ... there would be no economic goods, i.e. goods that are relatively scarce..." Scarcity is the limited availability of a commodity, which may be in demand in the market or by the commons. Scarcity also includes an individual's lack of resources to buy commodities. The opposite of scarcity is abundance. Scarcity plays a key role in economic theory, and it is essential for a "proper definition of economics itself."Montani G. (1987) Scarcity. In: Palgrave Macmillan (eds) ''The New Palgrave Dictionary of Economics''. Palgra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Disease
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structur ...

History Of Technology
The history of technology is the history of the invention of tools and techniques and is one of the categories of world history. Technology can refer to methods ranging from as simple as stone tools to the complex genetic engineering and information technology that has emerged since the 1980s. The term technology comes from the Greek word ''techne'', meaning art and craft, and the word logos, meaning word and speech. It was first used to describe applied arts, but it is now used to describe advancements and changes which affect the environment around us. New knowledge has also enabled people to create new things, and conversely, many scientific endeavors are made possible by technologies which assist humans in traveling to places they could not previously reach, and by scientific instruments by which we study nature in more detail than our natural senses allow. Since much of technology is applied science, technical history is connected to the history of science. Since techn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-renewable Resource
A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved (except in nuclear reactions, nuclear decay or atmospheric escape). Conversely, resources such as timber (when harvested sustainably) and wind (used to power energy conversion systems) are considered renewable resources, largely because their localized replenishment can occur within time frames meaningful to humans as well. Earth minerals and metal ores Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are presen ...

Free Market
In economics, a free market is an economic system in which the prices of goods and services are determined by supply and demand expressed by sellers and buyers. Such markets, as modeled, operate without the intervention of government or any other external authority. Proponents of the free market as a normative ideal contrast it with a regulated market, in which a government intervenes in supply and demand by means of various methods such as taxes or regulations. In an idealized free market economy, prices for goods and services are set solely by the bids and offers of the participants. Scholars contrast the concept of a free market with the concept of a coordinated market in fields of study such as political economy, new institutional economics, economic sociology and political science. All of these fields emphasize the importance in currently existing market systems of rule-making institutions external to the simple forces of supply and demand which create space for those ...

Marriage
Marriage, also called matrimony or wedlock, is a culturally and often legally recognized union between people called spouses. It establishes rights and obligations between them, as well as between them and their children, and between them and their in-laws. It is considered a cultural universal, but the definition of marriage varies between cultures and religions, and over time. Typically, it is an institution in which interpersonal relationships, usually sexual, are acknowledged or sanctioned. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity. A marriage ceremony is called a wedding. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, and religious purposes. Whom they marry may be influenced by gender, socially determined rules of incest, prescriptive marriage rules, parental choice, and individual desire. In some areas of the world, arrang ...

Abstinence
Abstinence is a self-enforced restraint from indulging in bodily activities that are widely experienced as giving pleasure. Most frequently, the term refers to sexual abstinence, but it can also mean abstinence from alcohol, drugs, food, etc. Because the regimen is intended to be a conscious act, freely chosen to enhance life, abstinence is sometimes distinguished from the psychological mechanism of repression. The latter is an unconscious state, having unhealthy consequences. Abstinence in religion Abstinence may arise from an ascetic over indulgent, hasidic point of view in natural ways of procreation, present in most faiths, or from a subjective need for spiritual discipline. In its religious context, abstinence is meant to elevate the believer beyond the normal life of desire, to a chosen ideal, by following a path of renunciation. In Judaism, Christianity and Islam, amongst others, pre-marital sex is prohibited. Judaism For Jews, the principal day of fast is Yom Kippur, ...

Malthusian Crisis
Malthusianism is the idea that population growth is potentially exponential while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population die off. This event, called a Malthusian catastrophe (also known as a Malthusian trap, population trap, Malthusian check, Malthusian crisis, Malthusian spectre, or Malthusian crunch) occurs when population growth outpaces agricultural production, causing famine or war, resulting in poverty and depopulation. Such a catastrophe inevitably has the effect of forcing the population to "correct" back to a lower, more easily sustainable level (quite rapidly, due to the potential severity and unpredictable results of the mitigating factors involved, as compared to the relatively slow time scales and well-understood processes governing unchecked growth or growth affected by preventive checks). Malthusianism has been linked to a variety of political and social movemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Growth
In mathematics, the term linear function refers to two distinct but related notions: * In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one. For distinguishing such a linear function from the other concept, the term affine function is often used. * In linear algebra, mathematical analysis, and functional analysis, a linear function is a linear map. As a polynomial function In calculus, analytic geometry and related areas, a linear function is a polynomial of degree one or less, including the zero polynomial (the latter not being considered to have degree zero). When the function is of only one variable, it is of the form :f(x)=ax+b, where and are constants, often real numbers. The graph of such a function of one variable is a nonvertical line. is frequently referred to as the slope of the line, and as the intercept. If ''a > 0'' then the gradient is positive and the graph slop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resources
Resource refers to all the materials available in our environment which are technologically accessible, economically feasible and culturally sustainable and help us to satisfy our needs and wants. Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources. They can also be classified as actual and potential on the basis of the level of development and use, on the basis of origin they can be classified as biotic and abiotic, and on the basis of their distribution, as ubiquitous and localised (private, community-owned, national and international resources). An item becomes a resource with time and developing technology. The benefits of resource utilization may include increased wealth, proper functioning of a system, or enhanced well-being. From a human perspective, a natural resource is anything obtained from the environment to satisfy human needs and wants.WanaGopa - Nyawakan From a broader biological or ecologic ...

Malthusian Growth Model
A Malthusian growth model, sometimes called a simple exponential growth model, is essentially exponential growth based on the idea of the function being proportional to the speed to which the function grows. The model is named after Thomas Robert Malthus, who wrote ''An Essay on the Principle of Population'' (1798), one of the earliest and most influential books on population."Malthus, An Essay on the Principle of Population: Library of Economics" Malthusian models have the following form: : P(t) = P_0e^ where * ''P''0 = ''P''(0) is the initial population size, * ''r'' = the population growth rate, which Ronald Fisher called the ''Malthusian parameter of population growth'' in The Genetical Theory of Natural Selection, and Alfred J. Lotka called the ''intrinsic rate of increase'', * ''t'' = time. The model can also been written in the form of a differential equation: : \frac = rP with initial condition: P(0)= P0 This model is often referred to as the ''exponential law''. It ...
