Alertness and visuospatial attention in clinical depression
No full textAbstract Background Cognitive deficits are a substantial burden in clinical depression. The present study considered dysfunction in the right-hemispheric attention network in depression, examining alertness and visuospatial attention. Methods Three computerized visuospatial attention tests and an alertness test were administered to 16 depressive patients and 16 matched healthy controls. Results Although no significant group effect was observed, alertness predicted reduced visuospatial performance in the left hemifield. Furthermore, sad mood showed a trend towards predicting left visual field omissions. Conclusions Decreased alertness may lead to lower left hemifield visuospatial attention; this mechanism may be responsible for a spatial bias to the right side in depression, even though treatment of depression and anxiety may reduce this cognitive deficit.</p

On the mathematical work of Klaus Floret
No full textIn section 1 of this article, a sketch of the life and the career of Klaus Floret is given. Then,in sections 2 to 5, the author reports on the part of the mathematical work of Klaus Floret which was devoted to four important topics in functional analysis in which Klaus worked and in which considerable progress was achieved during his lifetime. These topics are: locally convex inductive limits; bases and approximation properties; - -spaces and the "probleme des topologies"; tensor norms, operator ideals, spaces of polynomials. Some of the history of these topics is included, sometimes together with an account of some of the leading figures in the field. A prelude, an interlude and a coda present related remarks which do not fit in the main body of the article
Specificity and definiteness in sentence and discourse structure
No full textIn this paper, I argue that this informally given list of characteristics covers only a certain subclass of specific indefinites. […] In particular, I dispute the definition of specific indefinites as "the speaker has the referent in mind" as rather confusing if one is working with a semantic theory. Furthermore, I discuss "relative specificity", it. cases in which the specific indefinite does not exhibit wide, but intermediate or narrow scope behavior. Based on such data, I argue that specificity expresses a referential dependency between introduced discourse items. Informally speaking, the specificity of the indefinite expression something [...] expresses that the reference of the expression depends on the reference of another expression, here, on the expression a monk, not the speaker
Vaclav Klaus and "nature"
No full textThesis is based on the views of authors of sociology of knowledge (Berger, Luckman, Bourdieu) and authors of discourse analysis (Foucault, Fairclough). The central assumption is that knowledge is socially constructed and that this construction has its strong ideological and hierarchic aspects. Author is analyzing books and texts of Vaclav Klaus using the critical discourse analysis. Author is convinced that Vaclav Klaus has a substantive influence on public opinion in Czech Republic. Also author is convinced the struggle in the discussion over environmental topics is based in different basic assupmtions of discussion participant. Thus author decided to analyse the Vaclav Klaus's basic assumptions for the notions of nature and environment

Violence-related content in video game may lead to functional connectivity changes in brain networks as revealed by fMRI-ICA in young men
No full textIn violent video games, players engage in virtual aggressive behaviors. Exposure to virtual aggressive behavior induces short-term changes in players' behavior. In a previous study, a violence-related version of the racing game "Carmageddon TDR2000" increased aggressive affects, cognitions, and behaviors compared to its non-violence-related version. This study investigates the differences in neural network activity during the playing of both versions of the video game. Functional magnetic resonance imaging (fMRI) recorded ongoing brain activity of 18 young men playing the violence-related and the non-violence-related version of the video game Carmageddon. Image time series were decomposed into functional connectivity (FC) patterns using independent component analysis (ICA) and template-matching yielded a mapping to established functional brain networks. The FC patterns revealed a decrease in connectivity within 6 brain networks during the violence-related compared to the non-violence-related condition: three sensory-motor networks, the reward network, the default mode network (DMN), and the right-lateralized frontoparietal network. Playing violent racing games may change functional brain connectivity, in particular and even after controlling for event frequency, in the reward network and the DMN. These changes may underlie the short-term increase of aggressive affects, cognitions, and behaviors as observed after playing violent video games
