Meta
Meta (from the Greek μετά, '' meta'', meaning "after" or "beyond") is a prefix meaning "more comprehensive" or "transcending". In modern nomenclature, ''meta''- can also serve as a prefix meaning self-referential, as a field of study or endeavor ( metatheory: theory about a theory, metamathematics: mathematical theories about mathematics, meta-axiomatics or meta-axiomaticity: axioms about axiomatic systems, metahumor: joking about the ways humor is expressed, etc.). Original Greek meaning In Greek, the prefix ''meta-'' is generally less esoteric than in English; Greek ''meta-'' is equivalent to the Latin words ''post-'' or ''ad-''. The use of the prefix in this sense occurs occasionally in scientific English terms derived from Greek. For example: the term ''Metatheria'' (the name for the clade of marsupial mammals) uses the prefix ''meta-'' in the sense that the ''Metatheria'' occur on the tree of life adjacent to the '' Theria'' (the placental mammals).

Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce s ...

Meta-cognition
Metacognition is an awareness of one's thought processes and an understanding of the patterns behind them. The term comes from the root word ''meta'', meaning "beyond", or "on top of".Metcalfe, J., & Shimamura, A. P. (1994). ''Metacognition: knowing about knowing''. Cambridge, MA: MIT Press. Metacognition can take many forms, such as reflecting on one's ways of thinking and knowing when and how to use particular strategies for problem-solving. There are generally two components of metacognition: (1) knowledge about cognition and (2) regulation of cognition. Metamemory, defined as knowing about memory and mnemonic strategies, is an especially important form of metacognition.Dunlosky, J. & Bjork, R. A. (Eds.). ''Handbook of Metamemory and Memory''. Psychology Press: New York, 2008. Academic research on metacognitive processing across cultures is in the early stages, but there are indications that further work may provide better outcomes in cross-cultural learning between teachers and ...

Metamemory
Metamemory or Socratic awareness, a type of metacognition, is both the introspective knowledge of one's own memory capabilities (and strategies that can aid memory) and the processes involved in memory self-monitoring. This self-awareness of memory has important implications for how people learn and use memories. When studying, for example, students make judgments of whether they have successfully learned the assigned material and use these decisions, known as "judgments of learning", to allocate study time. History Descartes, among other philosophers, marveled at the phenomenon of what we now know as metacognition.Metcalfe, J. (2000). "Metamemory: Theory and data", pp. 197–211 in E. Tulving & F.I.M. Craik (Eds.), ''The Oxford Handbook of Memory''. New York: Oxford University Press. "It was not so much thinking that was indisputable to Descartes, but rather thinking ''about'' thinking. He could not imagine that the person engaged in such self-reflective processing did not exis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meta-emotion
Meta-emotion is "an organized and structured set of emotions and cognitions about the emotions, both one's own emotions and the emotions of others". This broad definition of meta-emotion sparked psychologists' interest in the topic, particularly regarding parental meta-emotion philosophy. Meta-emotion refers to the idea that whenever we elicit a certain emotion, we also deal with subsequent emotions regarding how we experienced the primary emotion. While some psychologists have examined the influence of meta-emotions on how individuals interpret and deal with their own and others' emotions, much of the literature regarding meta-emotion has focused on how parental meta-emotion affects the social-emotional development of their children. Meta-emotions can be short-term or long-term. The latter can be a source of discouragement or even psychological repression, or encouragement of specific emotions, having implications for personality traits, psychodynamics, family and group dynamics, ...

Metaprogramming
Metaprogramming is a programming technique in which computer programs have the ability to treat other programs as their data. It means that a program can be designed to read, generate, analyze or transform other programs, and even modify itself while running. In some cases, this allows programmers to minimize the number of lines of code to express a solution, in turn reducing development time. It also allows programs a greater flexibility to efficiently handle new situations without recompilation. Metaprogramming can be used to move computations from run-time to compile-time, to generate code using compile time computations, and to enable self-modifying code. The ability of a programming language to be its own metalanguage is called reflection. Reflection is a valuable language feature to facilitate metaprogramming. Metaprogramming was popular in the 1970s and 1980s using list processing languages such as LISP. LISP hardware machines were popular in the 1980s and enabled a ...

Metatheory
A metatheory or meta-theory is a theory whose subject matter is theory itself, aiming to describe existing theory in a systematic way. In mathematics and mathematical logic, a metatheory is a mathematical theory about another mathematical theory. Meta-theoretical investigations are part of the philosophy of science. A metatheory is not applied directly to practice, but may have applications to the practice of the field it studies. The emerging field of metascience seeks to use scientific knowledge to improve the practice of science itself. Examples of metatheories Metascience Metascience is the use of scientific methodology to study science itself. Metascience seeks to increase the quality of scientific research while reducing waste. It is also known as "''research on research''" and "''the science of science''", as it uses research methods to study how research is done and where improvements can be made. Metascience concerns itself with all fields of research and has been de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metatheria
Metatheria is a mammalian clade that includes all mammals more closely related to marsupials than to placentals. First proposed by Thomas Henry Huxley in 1880, it is a more inclusive group than the marsupials; it contains all marsupials as well as many extinct non-marsupial relatives. There are three extant subclasses of mammals, one being metatherians: # monotremes: egg laying mammals like the platypus and the echidna, #metatheria: marsupials, which includes three American orders ( Didelphimorphia, Paucituberculata and Microbiotheria) and four Australasian orders ( Notoryctemorphia, Dasyuromorphia, Peramelemorphia and Diprotodontia), and the # eutherians: placental mammals, consisting of four superorders divided into 21 orders. Metatherians belong to a subgroup of the northern tribosphenic mammal clade or Boreosphenida. They differ from all other mammals in certain morphologies like their dental formula, which includes about five upper and four lower incisors, a canin ...

Meta-joke
Self-referential humor, also known as self-reflexive humor, self-aware humor, or meta humor, is a type of comedic expression that—either directed toward some other subject, or openly directed toward itself—is self-referential in some way, intentionally alluding to the very person who is expressing the humor in a comedic fashion, or to some specific aspect of that same comedic expression. Self-referential humor expressed discreetly and surrealistically is a form of bathos. In general, self-referential humor often uses hypocrisy, oxymoron, or paradox to create a contradictory or otherwise absurd situation that is humorous to the audience. History Old Comedy of Classical Athens is held to be the first—in the extant sources—form of self-referential comedy. Aristophanes, whose plays form the only remaining fragments of Old Comedy, used fantastical plots, grotesque and inhuman masks and status reversals of characters to slander prominent politicians and court his audience's a ...

Metamathematics
Metamathematics is the study of mathematics itself using mathematical methods. This study produces metatheories, which are mathematical theories about other mathematical theories. Emphasis on metamathematics (and perhaps the creation of the term itself) owes itself to David Hilbert's attempt to secure the foundations of mathematics in the early part of the 20th century. Metamathematics provides "a rigorous mathematical technique for investigating a great variety of foundation problems for mathematics and logic" (Kleene 1952, p. 59). An important feature of metamathematics is its emphasis on differentiating between reasoning from inside a system and from outside a system. An informal illustration of this is categorizing the proposition "2+2=4" as belonging to mathematics while categorizing the proposition "'2+2=4' is valid" as belonging to metamathematics. History Metamathematical metatheorems about mathematics itself were originally differentiated from ordinary mathema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meta-discussion
{{refimprove, date=July 2009 The term meta-discussion means a discussion whose subject is a discussion. Meta-discussion explores such issues as the style of a discussion, its participants, the setting in which the discussion occurs, and the relationship of the discussion to other discussions on the same or different topics. It is one of many terms based on the inferred meaning of the "meta-" prefix. The etymology for the prefix dates back to use of ''Metaphysics'' as the title of the treatise by Aristotle that came after his works on physics in the traditional ordering of his books. The fundamental meaning of the prefix in Greek is simply "after." The modern, inferred meaning of a higher-order, self-referential consideration of the nature of an activity—rather than actual, first-level participation in the activity—has led to many neologisms such ameta-wiki Examples One of the most easily understood examples of meta-discussion occurs in the criticism of a literary work, ...
