It is often assumed that the information representations used in interactive information systems are grounded firmly and objectively in mathematics. This positivist view is at odds, however, with contemporary mathematics and philosophy of science, which sees subjective, social, and situated symbol systems — semiology — at the base of all human information use. We describe some of the reasons be...

The present paper aims at a synthesis of belief revision theory with the Sneed formalism known as the structuralist theory of science. This synthesis is brought about by a dynamisation of classical structuralism, with an abductive inference rule and base generated revisions in the style of Rott (2001). The formalism of prioritised default logic (PDL) serves as the medium of the synthesis. Why s...

The attempt to institute a viable structuralist explanatory project in the social sciences (in particular anthropology and sociology) has been beset, since its inception, with what some have considered to be insurmountable difficulties. Four such roadblocks deserve mention. 1) The first, I refer to as Piaget’s question [Piaget 1970, 113]: “how do [social] forms acquire structural organization?”...

The aim of this paper is to reveal the tacit assumptions of the logicist and structuralist theories on the nature of cardinal numbers. The privileged background theory is the representational theory of language with its main conjecture about necessary correspondence between metaphysical structure of reality and logical structure of language. In such a theory of language we meet a number of thes...

Behaviorist-Structural theory is one of the important theories in language learning. This a meeting between behavioral psychology and structuralist linguistics. The combination these two not only creates new principles views, but also has an impact on development learning, especially second languages. study aims to describe behavioralist-structural view its application Arabic research conceptua...

One of the leading schools in modern unemployment theory is the "Structuralist" theory of the "natural" or equilibrium rate of unemployment (NRU) started by Edmund S. Phelps (see Blanchard 2000, p. 255; Phelps 1994, 2005b; Fitoussi et al. 2000; Phelps and Zoega 2004). In fact, it can be understood as a kind of meta-theory of unemployment (Phelps 2002). In a nutshell, Structuralist theory postul...

Recent historiography of 19th century biology supports the revision of two traditional doctrines about the history of biology. First, the most important and widespread biological debate around the time of Darwin was not evolution versus creation, but biological functionalism versus structuralism. Second, the “idealist” and “typological” structuralist theories of the time were not particularly a...
