Summary  

Let Fn, n≧ 1, denote the sequence of generic filiform (connected, simply connected) Lie groups. Here we study, for each Fn, the infinite dimensional simple quotients of the group C*-algebra of (the most obvious) one of its discrete cocompact subgroups Dn. For Dn, the most attractive concrete faithful representations are given in terms of Anzai flows, in analogy with the representations of the discrete Heisenberg group H 3 G 3 on L 2(T) that result from the irrational rotation flows on T; the representations of Dn generate infinite-dimensional simple quotients An of the group C*-algebra C*(Dn). For n>1, there are other infinite-dimensional simple quotients of C*(Dn) arising from non-faithful representations of Dn. Flows for these are determined, and they are also characterized and represented as matrix algebras over simple affine Furstenberg transformation group C*-algebras of the lower dimensional tori.

We investigate various aspects of stochastic integration in finite von Neumann algebras. For integration with respect to a bounded L 2 -martingale the idea of treating the integral as a bounded operator is developed. Several classes of integrable processes are defined, it turns out that some of them form a Banach or C *-algebra. We find representations of these algebras and establish relations between the von Neumann algebras generated by these representations. Finally, we characterize the range of the stochastic integration operator.

This study presents evidence concerning semantic representation in bilingual memory. A vast majority of the early research on this topic proposed that fluent bilinguals access semantic representations that are shared across their two languages. More recent research proves that the question is not as simple as that. Bilinguals can sometimes use shared semantic representations across their two languages, but the conditions under which they can do so are constrained by the nature of the material, by the form of the task, by the level of proficiency in the second language, and by the lexical-level connections between the two languages. The present study provides an analysis of some psycholinguistic tests carried out among bilingual and bicultural people within a new framework proposing that there are asymmetries in the strength of the connections between lexical representations in different languages and between lexical representations and concepts. The author examines bilingual and bicultural semantic representations and their linguistic realisations, and the switching attitudes of bilinguals through the analysis of three tests conducted among bilingual and bicultural subjects.

Abstract  

Scientific reality is a multi-sided phenomenon which cannot be described in a single and authoritative way. The descriptions of scientific research areas differ if one compares the definitions of science policy programmes with expert judgments in the peer-review process. Bibliometric measurements function as an intermediate representation of science. To make them useful and compatible with other representations they have to be translated. The difficulties of mutual translation of these different delineations of scientific research areas are demonstrated in two case studies (marine sciences and multiple sclerosis research) where each of these three different representations of science is supported by empirical results.
