Let $G$ be a locally compact group and let $1 \le p < \infty.$ Recently, Chen et al. characterized hypercyclic, supercyclic and chaotic weighted translations on locally compact groups and their homogeneous spaces. There has been an increasing interest in studying the disjoint hypercyclicity acting on various spaces of holomorphic functions. In this note, we will study disjoint hypercyclic and disjoint supercyclic powers of weighted translation operators on the Lebesgue space $L^p(G)$ in terms of the weights. Sufficient and necessary conditions for disjoint hypercyclic and disjoint supercyclic powers of weighted translations generated by aperiodic elements on groups will be given., Liang Zhang, Hui-Qiang Lu, Xiao-Mei Fu, Ze-Hua Zhou., and Obsahuje bibliografické odkazy
This text presents an analysis of the recent emphasis in HIV/AIDS prevention campaigns: the discursive constructions of HIV/AIDS as an issue of risk and its management. Specifically, the text discusses the prevention materials produced by state-funded institutions in the Czech Republic. The aim of the text is twofold: First, it analyses the specific discourse (and rationality) of risk that permeates HIV/AIDS prevention in relation to and as a part of modern biopolitics and (self-)governance. Second, the text examines the discourse of risk for its gendered implications and its re-inscription of gendered power inequalities., Kateřina Kolářová., Obsahuje bibliografii, and Anglické resumé
The article offers a comparison of the development of institutions of care for children under the age of three in France and in the Czech Republic. It explains the differences in the forms of institutions, policies and the level of state support using a comparative analysis of the discourses of childcare that have existed in the two countries since the end of the Second World War. Expert discourses in particular were found to have an important role in the development of institutions and policies: psychological discursive framings had a strong influence on the public discourse, political decisions and the resulting form of institutions. While in France mainly empirically‑oriented psychologists and pedagogues entered the debate, in Czechoslovakia/the Czech Republic the discursive arena was dominated by clinical psychologists and paediatricians. Other influential factors were identified, such as the economic situation, political actors, social movements; and sequencing of events; but the expert discourse was proved to be crucial for the understanding of the divergent development of childcare institutions in the two countries., Radka Dudová, Hana Hašková., Obsahuje bibliografii, and Anglické resumé
This interdisciplinary work explores current controversy over the collective identity of Romani and reasons for their social predicament. The first position, associated with Romani studies and identity politics, sees all Romani as a part of an ‘ethnic group’, and connects their plight to ‘racial’ discrimination and intolerance. Some anthropologists and social policy-makers call this ‘primordialism’ and deconstruct the notion of a unitary and natural ‘Romani nation’, maintaining most ghetto inhabitants are only classified as ‘Romani’ and their identity derives from their ‘sociál exclusion’. Matching policies are advocated. The author combines contemporary anthropological approaches to the identity construction with theories of discourse to conceptualize the debate, completing the framework with self-reflection of social science. The method of Critical Discourse Analysis is applied in examining corpora of academic and specialized writing, policy papers and media texts for the discourse construction of identity. Arguing that both discourses are differentiated instantiations of the same diagram of power normalizing ‘troublesome’ subjectivities, the author touches upon the ethical responsibility of scientists deconstructing essentialist representations of identities and circulating their ovm constructs instead.
