Metafiction
Metafiction is a form of fiction which emphasises its own narrative structure in a way that continually reminds the audience that they are reading or viewing a fictional work. Metafiction is self-conscious about language, literary form, and story-telling, and works of metafiction directly or indirectly draw attention to their status as artifacts. Metafiction is frequently used as a form of parody or a tool to undermine literary conventions and explore the relationship between literature and reality, life, and art. Although metafiction is most commonly associated with postmodern literature that developed in the mid-20th century, its use can be traced back to much earlier works of fiction, such as ''The Canterbury Tales'' (Geoffrey Chaucer, 1387), ''Don Quixote'' (Miguel de Cervantes, 1605), ''The Life and Opinions of Tristram Shandy, Gentleman'' (Laurence Sterne, 1759), and '' Vanity Fair'' (William Makepeace Thackeray, 1847). Metafiction became particularly prominent in the 1960 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reflexive Pronoun
A reflexive pronoun is a pronoun that refers to another noun or pronoun (its antecedent) within the same sentence. In the English language specifically, a reflexive pronoun will end in ''-self'' or ''-selves'', and refer to a previously named noun or pronoun (''myself'', ''yourself'', ''ourselves'', ''themselves'', etc.). English intensive pronouns, used for emphasis, take the same form. In generative grammar, a reflexive pronoun is an anaphor that must be bound by its antecedent (see binding). In a general sense, it is a noun phrase that obligatorily gets its meaning from another noun phrase in the sentence. Different languages have different binding domains for reflexive pronouns, according to their structure. Origins and usage In Indo-European languages, the reflexive pronoun has its origins in Proto-Indo-European. In some languages, some distinction exists between normal object and reflexive pronouns, mainly in the third person: whether one says "I like me" or "I ...

Reflexive Verb
In grammar, a reflexive verb is, loosely, a verb whose direct object is the same as its subject; for example, "I wash myself". More generally, a reflexive verb has the same semantic agent and patient (typically represented syntactically by the subject and the direct object). For example, the English verb ''to perjure'' is reflexive, since one can only perjure ''oneself''. In a wider sense, the term refers to any verb form whose grammatical object is a reflexive pronoun, regardless of semantics; such verbs are also more broadly referred to as pronominal verbs, especially in grammars of the Romance languages. Other kinds of pronominal verbs are reciprocal (''they killed each other''), passive (''it is told''), subjective, idiomatic. The presence of the reflexive pronoun changes the meaning of a verb, e.g. Spanish ''abonar'' to pay, ''abonarse'' to subscribe. There are languages that have explicit morphology or syntax to transform a verb into a reflexive form. In many languages, ref ...

Reflexive Relation
In mathematics, a binary relation ''R'' on a set ''X'' is reflexive if it relates every element of ''X'' to itself. An example of a reflexive relation is the relation " is equal to" on the set of real numbers, since every real number is equal to itself. A reflexive relation is said to have the reflexive property or is said to possess reflexivity. Along with symmetry and transitivity, reflexivity is one of three properties defining equivalence relations. Definitions Let R be a binary relation on a set X, which by definition is just a subset of X \times X. For any x, y \in X, the notation x R y means that (x, y) \in R while "not x R y" means that (x, y) \not\in R. The relation R is called if x R x for every x \in X or equivalently, if \operatorname_X \subseteq R where \operatorname_X := \ denotes the identity relation on X. The of R is the union R \cup \operatorname_X, which can equivalently be defined as the smallest (with respect to \subseteq) reflexive relation on X ...

Command Verb
In human–computer interaction, a command verb is a verb that appears in a user interface and is used for the user to tell the computer to do something (rather than vice versa). For instance, the words "edit" and "view" and "help" that appear in the Web browser A web browser is application software for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on ... menu are all clearly verbs. Other items such as "file" or "favorites" or "tools" are nouns, but the verb appears in the submenu, for instance, "save", "open", "send", "treat", "add to", or "organize". A Web page typically includes a few such verbs also, typically including "search", "log in" and perhaps "edit this page". A reflexive user interface is one in which commands and perhaps other controls are defined in the interface itself. User interfaces {{Soft-eng-st ...

Reflexive Operator Algebra
In functional analysis, a reflexive operator algebra ''A'' is an operator algebra that has enough invariant subspaces to characterize it. Formally, ''A'' is reflexive if it is equal to the algebra of bounded operators which leave invariant each subspace left invariant by every operator in ''A''. This should not be confused with a reflexive space. Examples Nest algebras are examples of reflexive operator algebras. In finite dimensions, these are simply algebras of all matrices of a given size whose nonzero entries lie in an upper-triangular pattern. In fact if we fix any pattern of entries in an ''n'' by ''n'' matrix containing the diagonal, then the set of all ''n'' by ''n'' matrices whose nonzero entries lie in this pattern forms a reflexive algebra. An example of an algebra which is ''not'' reflexive is the set of 2 × 2 matrices :\left\. This algebra is smaller than the Nest algebra :\left\ but has the same invariant subspaces, so it is not reflexive. If ''T'' is a fix ...

Reflexive Space
In the area of mathematics known as functional analysis, a reflexive space is a locally convex topological vector space (TVS) for which the canonical evaluation map from X into its bidual (which is the strong dual of the strong dual of X) is an isomorphism of TVSs. Since a normable TVS is reflexive if and only if it is semi-reflexive, every normed space (and so in particular, every Banach space) X is reflexive if and only if the canonical evaluation map from X into its bidual is surjective; in this case the normed space is necessarily also a Banach space. In 1951, R. C. James discovered a Banach space, now known as James' space, that is reflexive but is nevertheless isometrically isomorphic to its bidual (any such isomorphism is thus necessarily the canonical evaluation map). Reflexive spaces play an important role in the general theory of locally convex TVSs and in the theory of Banach spaces in particular. Hilbert spaces are prominent examples of reflexive Banach spaces. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reflexive Bilinear Form
In mathematics, a bilinear form is a bilinear map on a vector space (the elements of which are called '' vectors'') over a field ''K'' (the elements of which are called ''scalars''). In other words, a bilinear form is a function that is linear in each argument separately: * and * and The dot product on \R^n is an example of a bilinear form. The definition of a bilinear form can be extended to include modules over a ring, with linear maps replaced by module homomorphisms. When is the field of complex numbers , one is often more interested in sesquilinear forms, which are similar to bilinear forms but are conjugate linear in one argument. Coordinate representation Let be an -dimensional vector space with basis . The matrix ''A'', defined by is called the ''matrix of the bilinear form'' on the basis . If the matrix represents a vector with respect to this basis, and analogously, represents another vector , then: B(\mathbf, \mathbf) = \mathbf^\textsf A\mathbf = \ ...

Reflexive Antagonism
Reciprocal inhibition describes the relaxation of muscles on one side of a joint to accommodate contraction on the other side. In some allied health disciplines, this is known as reflexive antagonism. The central nervous system sends a message to the agonist muscle to contract. The tension in the antagonist muscle is activated by impulses from motor neurons, causing it to relax. Mechanics Joints are controlled by two opposing sets of muscles called extensors and flexors, that work in synchrony for smooth movement. When a muscle spindle is stretched, the stretch reflex is activated, and the opposing muscle group must be inhibited to prevent it from working against the contraction of the homonymous muscle. This inhibition is accomplished by the actions of an inhibitor interneuron in the spinal cord. The afferent of the muscle spindle bifurcates in the spinal cord. One branch innervates the alpha motor neuron that causes the homonymous muscle to contract, producing the reflex. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reflexive Entertainment
Reflexive Entertainment was a video game developer based in Lake Forest, California. The company was cofounded by Lars Brubaker, Ernie Ramirez, James C. Smith and Ion Hardie in 1997. They developed nineteen games independently (for Microsoft Windows, Xbox 360 and Mac platforms), published two games, started distribution of downloadable casual games on their online Arcade, created a division of their Arcade entirely devoted to Mac games for Mac users and started hosting ad supported free online web browser games. In 2005, Reflexive's ''Wik and the Fable of Souls'' won three awards at the 2005 Independent Games Festival which included Innovation in Visual Art, Innovation in Game Design and the Seumas McNally Award For Independent Game Of The Year. In October 2008, Reflexive Entertainment was acquired by Amazon.com. On February 3, 2009, Amazon.com began hosting casual game content for internet download. On March 31, 2010, Reflexive announced plans to stop selling games through its a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reflexivity (social Theory)
In epistemology, and more specifically, the sociology of knowledge, reflexivity refers to circular relationships between cause and effect, especially as embedded in human belief structures. A reflexive relationship is bidirectional with both the cause and the effect affecting one another in a relationship in which neither can be assigned as causes or effects. Within sociology more broadly—the field of origin—reflexivity means an act of self-reference where examination or action "bends back on", refers to, and affects the entity instigating the action or examination. It commonly refers to the capacity of an agent to recognise forces of socialisation and alter their place in the social structure. A low level of reflexivity would result in individuals shaped largely by their environment (or "society"). A high level of social reflexivity would be defined by individuals shaping ''their own'' norms, tastes, politics, desires, and so on. This is similar to the notion of autonomy. ( ...
