Anti-rival Good
“Anti-rival good” is a neologism suggested by Steven Weber. According to his definition, it is the opposite of a rival good. The more people share an anti-rival good, the more utility each person receives. Examples include software and other information goods created through the process of commons-based peer production. An anti-rival good meets the test of a public good because it is non-excludable (freely available to all) and non-rival (consumption by one person does not reduce the amount available for others). However, it has the additional quality of being created by private individuals for common benefit without being motivated by pure altruism, because the individual contributor also receives benefits from the contributions of others. Free open-source software Lawrence Lessig described free and open-source software as anti-rivalrous: "It's not just that code is non-rival; it's that code in particular, and (at least some) knowledge in general, is, as Weber calls i ...

Neologism
A neologism Greek νέο- ''néo''(="new") and λόγος /''lógos'' meaning "speech, utterance"] is a relatively recent or isolated term, word, or phrase that may be in the process of entering common use, but that has not been fully accepted into mainstream language. Neologisms are often driven by changes in culture and technology. In the process of language formation, neologisms are more mature than '' protologisms''. A word whose development stage is between that of the protologism (freshly coined) and neologism (new word) is a ''prelogism''. Popular examples of neologisms can be found in science, fiction (notably science fiction), films and television, branding, literature, jargon, cant, linguistics, the visual arts, and popular culture. Former examples include '' laser'' (1960) from Light Amplification by Stimulated Emission of Radiation; ''robot'' (1941) from Czech writer Karel Čapek's play '' R.U.R. (Rossum's Universal Robots)''; and ''agitprop'' (1930) (a portmanteau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Language
In neuropsychology, linguistics, and philosophy of language, a natural language or ordinary language is any language that has evolved naturally in humans through use and repetition without conscious planning or premeditation. Natural languages can take different forms, such as speech or signing. They are distinguished from constructed and formal languages such as those used to program computers or to study logic. Defining natural language Natural language can be broadly defined as different from * artificial and constructed languages, e.g. computer programming languages * constructed international auxiliary languages * non-human communication systems in nature such as whale and other marine mammal vocalizations or honey bees' waggle dance. All varieties of world languages are natural languages, including those that are associated with linguistic prescriptivism or language regulation. ( Nonstandard dialects can be viewed as a wild type in comparison with stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metcalf's Law
Metcalfe's law states that the value of a telecommunications network is Quadratic growth, proportional to the square of the number of connected users of the system (''n''2). First formulated in this form by George Gilder in 1993, and attributed to Robert Metcalfe in regard to Ethernet, Metcalfe's law was originally presented, c. 1980, not in terms of users, but rather of "compatible communicating devices" (e.g., fax machines, telephones). Only later with the history of the Internet, globalization of the Internet did this law carry over to users and networks as its original intent was to describe Ethernet connections. Network effects Metcalfe's law characterizes many of the network effects of communication technologies and networks such as the Internet, social networking and the World Wide Web. Former Chairman of the U.S. Federal Communications Commission Reed Hundt said that this law gives the most understanding to the workings of the Internet. Metcalfe's Law is related to the f ...

Network Effect
In economics, a network effect (also called network externality or demand-side economies of scale) is the phenomenon by which the value or utility a user derives from a good or service depends on the number of users of compatible products. Network effects are typically positive, resulting in a given user deriving more value from a product as more users join the same network. The adoption of a product by an additional user can be broken into two effects: an increase in the value to all other users ( "total effect") and also the enhancement of other non-users' motivation for using the product ("marginal effect"). Network effects can be direct or indirect. Direct network effects arise when a given user's utility increases with the number of other users of the same product or technology, meaning that adoption of a product by different users is complementary. This effect is separate from effects related to price, such as a benefit to existing users resulting from price decreases as ...

Sandwich
A sandwich is a food typically consisting of vegetables, sliced cheese or meat, placed on or between slices of bread, or more generally any dish wherein bread serves as a container or wrapper for another food type. The sandwich began as a portable, convenient finger food in the Western world, though over time it has become prevalent worldwide. In the 21st century there has been considerable debate over the precise definition of ''sandwich''; and specifically whether a hot dog or open sandwich can be categorized as such. In the United States, the Department of Agriculture and the Food and Drug Administration are the responsible agencies. The USDA uses the definition, "at least 35% cooked meat and no more than 50% bread" for closed sandwiches, and "at least 50% cooked meat" for open sandwiches. In Britain, the British Sandwich Association defines a sandwich as "any form of bread with a filling, generally assembled cold", a definition which includes wraps and bagels, but excl ...

Renting
Renting, also known as hiring or letting, is an agreement where a payment is made for the temporary use of a good, service or property owned by another. A gross lease is when the tenant pays a flat rental amount and the landlord pays for all property charges regularly incurred by the ownership. An example of renting is equipment rental. Renting can be an example of the sharing economy. History Various types of rent are referenced in Roman law: rent (''canon'') under the long leasehold tenure of Emphyteusis; rent (''reditus'') of a farm; ground-rent (''solarium''); rent of state lands (''vectigal''); and the annual rent (''prensio'') payable for the ''jus superficiarum'' or right to the perpetual enjoyment of anything built on the surface of land. Reasons for renting There are many possible reasons for renting instead of buying, for example: *In many jurisdictions (including India, Spain, Australia, United Kingdom and the United States) rent paid in a trade or business is ...

Pogo (comic Strip)
''Pogo'' was a daily comic strip that was created by cartoonist Walt Kelly and syndicated to American newspapers from 1948 until 1975. Set in the Okefenokee Swamp in the Southeastern United States, ''Pogo'' followed the adventures of its anthropomorphic animal characters, including the title character, an opossum. The strip was written for both children and adults, with layers of social and political satire targeted to the latter. ''Pogo'' was distributed by the Post-Hall Syndicate. The strip earned Kelly a Reuben Award in 1951. History Walter Crawford Kelly Jr. was born in Philadelphia on August 25, 1913. His family moved to Bridgeport, Connecticut, when he was only two. He went to California at age 22 to work on ''Donald Duck'' cartoons at Walt Disney Studios in 1935. He stayed until the animators' strike in 1941 as an animator on ''The Nifty Nineties'', ''The Little Whirlwind'', ''Pinocchio, Fantasia, Dumbo'' and '' The Reluctant Dragon''. Kelly then worked for Dell Comics, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pareto Efficiency
Pareto efficiency or Pareto optimality is a situation where no action or allocation is available that makes one individual better off without making another worse off. The concept is named after Vilfredo Pareto (1848–1923), Italian civil engineer and economist, who used the concept in his studies of economic efficiency and income distribution. The following three concepts are closely related: * Given an initial situation, a Pareto improvement is a new situation where some agents will gain, and no agents will lose. * A situation is called Pareto-dominated if there exists a possible Pareto improvement. * A situation is called Pareto-optimal or Pareto-efficient if no change could lead to improved satisfaction for some agent without some other agent losing or, equivalently, if there is no scope for further Pareto improvement. The Pareto front (also called Pareto frontier or Pareto set) is the set of all Pareto-efficient situations. Pareto originally used the word "optimal" fo ...

Data Set
A data set (or dataset) is a collection of data. In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question. The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set. Data sets can also consist of a collection of documents or files. In the open data discipline, data set is the unit to measure the information released in a public open data repository. The European data.europa.eu portal aggregates more than a million data sets. Some other issues ( real-time data sources, non-relational data sets, etc.) increases the difficulty to reach a consensus about it. Properties Several characteristics define a data set's structure and properties. These include the number and types of the attributes or variables, and various statistical measures appli ...

Gift Economy
A gift economy or gift culture is a system of exchange where Anthropological theories of value, valuables are not sold, but rather given without an explicit agreement for immediate or future rewards. Social norms and customs govern giving a gift in a gift culture; although there is some expectation of reciprocity, gifts are not given in an explicit exchange of goods or services for money, or some other commodity or service.R. Kranton: ''Reciprocal exchange: a self-sustaining system'', American Economic Review, V. 86 (1996), Issue 4 (September), pp. 830–851 This contrasts with a barter economy or a market economy, where goods and services are primarily explicitly exchanged for value received. The nature of gift economies is the subject of a foundational debate in anthropology. Anthropological research into gift economies began with Bronisław Malinowski's description of the Kula ring in the Trobriand Islands during World War I. The Kula trade appeared to be gift-like since Trobri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reciprocity (cultural Anthropology)
In cultural anthropology, reciprocity refers to the non-market exchange of goods or labour ranging from direct barter (immediate exchange) to forms of gift exchange where a return is eventually expected (delayed exchange) as in the exchange of birthday gifts. It is thus distinct from the true gift, where no return is expected. When the exchange is immediate, as in barter, it does not create a social relationship. When the exchange is delayed, it creates both a relationship as well as an obligation for a return (i.e. debt). Hence, some forms of reciprocity can establish hierarchy if the debt is not repaid. The failure to make a return may end a relationship between equals. Reciprocal exchanges can also have a political effect through the creation of multiple obligations and the establishment of leadership, as in the gift exchanges (Moka) between Big Men in Melanesia. Some forms of reciprocity are thus closely related to redistribution, where goods and services are collected by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource shari ...
