In generative grammar and related approaches, the logical form (LF) of a linguistic expression is the variant of its syntactic structure which undergoes semantic interpretation. It is distinguished from phonetic form , the structure which corresponds to a sentence's pronunciation.
The term 'functionalism' or 'functional linguistics' became controversial in the 1980s with the rise of a new wave of evolutionary linguistics. Johanna Nichols argued that the meaning of 'functionalism' had changed, and the terms formalism and functionalism should be taken as referring to generative grammar, and the emergent linguistics of Paul Hopper and Sandra Thompson, respectively; and ...
[1] This approach looks at society through a macro-level orientation, which is a broad focus on the social structures that shape society as a whole, [1] and believes that society has evolved like organisms. [2] This approach looks at both social structure and social functions.
Emile Durkheim based his sociological concept on 'structure' and 'function', and from his work emerged the sociological approach of structural functionalism. Apart from Durkheim's use of the term structure, the semiological concept of Ferdinand de Saussure became fundamental for structuralism. Saussure conceived language and society as a system ...
An object carrying this information is known as a structure (of signature σ), or σ-structure, or L-structure (of language L), or as a "model". The information specified in the interpretation provides enough information to give a truth value to any atomic formula, after each of its free variables , if any, has been replaced by an element of ...
Output is a function of the number of workers and can be written Y(N). [Hicks writes x=f x (N x) and y=f y (N y).] M is the externally determined money supply. r is the interest rate. [Hicks denotes it by i.] We let P be the price level, i.e. the money price of a unit of real output. Hicks does not give it a symbol.
In the history of metaphysics specifically, this function is fulfilled by different terms (which Derrida says are always associated with presence): "eidos, archè, telos, energia, ousia (essence, existence, substance, subject) aletheia, transcendentality, consciousness, or conscience, God, man, and so forth."
Formally, a structure can be defined as a triple = (,,) consisting of a domain, a signature, and an interpretation function that indicates how the signature is to be interpreted on the domain. To indicate that a structure has a particular signature σ {\displaystyle \sigma } one can refer to it as a σ {\displaystyle \sigma } -structure.
