When words are read, the visual cortex is activated, independent of whether visual or motor associations are elicited. This word-evoked brain activity is significantly influenced by semantic meaning. Such effects occur very early after stimulus presentation (at latencies between 80 and 130 msec), indicating that semantic meaning activates different neuronal assemblies in the human visual cortex when words are processed.

This paper is an introduction into the theory of cellular spaces. From the more general model of nets of abstract cells which are interpreted by finite automata, it is shown how the model of cellular spaces is achieved by specialization. Cellular spaces are extremely homogeneous in function and in geometry. The relation between local and global behavior is regarded as the main topic of the theory. After a formal definition of cellular spaces, it is shown that not all functions of (...) the configuration space are induced by cellular spaces. In addition, the Garden-of-Eden problem is discussed, and a simple self-reproduction property is explained. (shrink)

Laws are true lawlike sentences. But what is lawlikeness? Much effort went into investigating the issue, but the richer the concert of opinions became, the more apparent their deficiencies became too, and with it the profound importance of the issue for epistemology and philosophy of science.

A complete recursive description of noetherian linear _KL_-algebras is given. _L_-algebras form a quantum structure that occurs in algebraic logic, combinatorial group theory, measure theory, geometry, and in connection with solutions to the Yang-Baxter equation. It is proved that the self-similar closure of a noetherian linear _KL_-algebra is determined by its partially ordered set of primes, and that its elements admit a unique factorization by a decreasing sequence of prime elements.

This is the first complete edition of Schleiermacher's 1820/21 lectures on education, which have hitherto only been available in a drastically abridged version concentrating on the topic of "Punishment and discipline". Notes taken by an unknown student, and published here in modern spelling, clearly show that this concentration does not do justice to Schleiermacher's theory of education. The text is accompanied by a detailed introduction, numerous explanatory notes and a comprehensive subject index.

Como Émile Durkheim, Max Weber, Werner Sombart, Georg Simmel y Vilfredo Pareto et al., Ferdinand Tönnies (1855-1936) perteneció a una generación de académicos que llegaron a ser los padres fundadores de la sociología moderna. Tönnies usó el contractualismo de Hobbes para concebir una concepción prop..
