Determinants of collective behavior, as suggested by the social identity or self-categorization approach and social movement research, were examined in 2 field studies. Study 1 was conducted in the context of the older people's movement in Germany and Study 2 in the context of the gay movement in the United States. Both studies yielded similar results(More)
RNA interference is a conserved mechanism that regulates gene expression in response to the presence of double-stranded (ds)RNAs. The RNase III-like enzyme Dicer first cleaves dsRNA into 21-23-nucleotide small interfering RNAs (siRNAs). In the effector step, the multimeric RNA-induced silencing complex (RISC) identifies messenger RNAs homologous to the(More)
The paper presents the work of the Elena project. The contribution of this paper is twofold: The first part of the paper elaborates on the notion of learning services. Learning services are differentiated from learning objects and put in the context of web services. A model for learning services is introduced and current limitations of learning object(More)
In 2 laboratory experiments, the tendency to stereotype oneself in terms of one's group membership as a function of the social context was examined. Experiment 1 examined the effects of relative in-group size on self-stereotyping. The results confirmed the prediction that minority members are more likely than majority members to stereotype themselves.(More)
Many cellular functions involve multi-domain proteins, which are composed of structurally independent modules connected by flexible linkers. Although it is often well understood how a given domain recognizes a cognate oligonucleotide or peptide motif, the dynamic interaction of multiple domains in the recognition of these ligands remains to be(More)
The authors conducted a panel study with two points of measurement throughout a 12-month interval in the context of the German gay movement to test the predictive power of collective identification in subsequent actual social movement participation. Regression analyses including cross-lagged panel analyses clearly confirmed the hypothesized unique(More)
This paper illustrates how internet-based learning information systems can be used to reengineer undergraduate teaching in the age of mass higher education. We describe current problems of undergraduate teaching by using an example of an introductory course in information technology at the Vienna University of Economics and Business Administration. We argue(More)
This research examined the interplay of group formation and individualization processes with a particular emphasis on minority and majority groups. First, a 2-component theory of individuality that distinguishes between individuality as independence and as differentiation from other people was presented, tested, and cross-validated in 2 questionnaire(More)
Neuronal Fe65 is a central adapter for the intracellular protein network of Alzheimer's disease related amyloid precursor protein (APP). It contains a unique tandem array of phosphotyrosine-binding (PTB) domains that recognize NPXY internalization motifs present in the intracellular domains of APP (AICD) and the low-density lipoprotein receptor-related(More)
