On the geometry of Siegel-Jacobi domains

We study the holomorphic unitary representations of the Jacobi group based on Siegel-Jacobi domains. Explicit polynomial orthonormal bases of the Fock spaces based on the Siegel-Jacobi disk are obtained. The scalar holomorphic discrete series of the Jacobi group for the Siegel-Jacobi disk is constructed and polynomial orthonormal bases of the representation spaces are given.Comment: 15 pages, Latex, AMS fonts, paper presented at the the International Conference "Differential Geometry and Dynamical Systems", August 25-28, 2010, University Politehnica of Bucharest, Romani

Information and Communication Flows through Community Multimedia Centers: Perspectives from Mozambican Communities.

Community multimedia centers (CMCs) are considered by initiating agencies as instruments able to inform, entertain and educate the population, as well as to offer them a voice into knowledge society and to public initiatives. This article presents a quali-quantitative content analysis of 230 interviews held with staff members, users of the venues, people of the community who listen to their radio component but do not use their telecenters, and community members not using CMCs. The sample includes 10 CMCs around Mozambique. The purpose of the study is to investigate the perception of local communities of inbound, outbound, and shared information and communication flows connected to CMCs. Results highlight how CMCs are perceived as inbound information enablers, mostly by means of their community radio component, and as means to share information and communication within the communities' boundaries. Yet, CMCs still do not appear to be widely recognized as participation means to a reality that transcends the communities' physical borders

Social representations and the politics of participation

Recent work has called for the integration of different perspectives into the field of political psychology (Haste, 2012). This chapter suggests that one possible direction that such efforts can take is studying the role that social representations theory (SRT) can play in understanding political participation and social change. Social representations are systems of common-sense knowledge and social practice; they provide the lens through which to view and create social and political realities, mediate people's relations with these sociopolitical worlds and defend cultural and political identities. Social representations are therefore key for conceptualising participation as the activity that locates individuals and social groups in their sociopolitical world. Political participation is generally seen as conditional to membership of sociopolitical groups and therefore is often linked to citizenship. To be a citizen of a society or a member of any social group one has to participate as such. Often political participation is defined as the ability to communicate one's views to the political elite or to the political establishment (Uhlaner, 2001), or simply explicit involvement in politics and electoral processes (Milbrath, 1965). However, following scholars on ideology (Eagleton, 1991; Thompson, 1990) and social knowledge (Jovchelovitch, 2007), we extend our understanding of political participation to all social relations and also develop a more agentic model where individuals and groups construct, develop and resist their own views, ideas and beliefs. We thus adopt a broader approach to participation in comparison to other political-psychological approaches, such as personality approaches (e.g. Mondak and Halperin, 2008) and cognitive approaches or, more recently, neuropsychological approaches (Hatemi and McDermott, 2012). We move away from a focus on the individual's political behaviour and its antecedents and outline an approach that focuses on the interaction between psychological and political phenomena (Deutsch and Kinnvall, 2002) through examining the politics of social knowledge

Fracking in the UK press: threat dynamics in an unfolding debate

Shale gas is a novel source of fossil fuel which is extracted by induced hydraulic fracturing, or “fracking”. This article examines the socio-political dimension of fracking as manifested in the UK press at three key temporal points in the debate on the practice. Three newspaper corpora were analysed qualitatively using Thematic Analysis and Social Representations Theory. Three overarching themes are discussed: “April–May 2011: From Optimism to Scepticism”; “November 2011: (De-)Constructing and Re-Constructing Risk and Danger”; “April 2012: Consolidating Social Representations of Fracking”. In this article, we examine the emergence of and inter-relations between competing social representations, discuss the dynamics of threat positioning and show how threat can be re-construed in order to serve particular socio-political ends in the debate on fracking

Grasping the dialogical nature of acculturation

In this interesting article, Andreouli (2013). Identity and acculturation: The case of naturalised citizens in Britain. Culture & Psychology, 19, 1–47) presents a dialogical perspective on acculturation. To support this perspective, the author integrates the Dialogical Self Theory and the Social Representations Theory. Drawing on her theoretical explanation, we develop a conceptual review focused on two pairs of constructs – social representations/I-positions and polyphasia/polyphonia. Andreouli’s empirical study allowed her to operationalize some critiques about the two-dimensional perspective and its strategies on acculturation. Nevertheless, it seems that the author ends up replicating a more conventional and dual way of thinking. Their results give us privileged access to the negotiation of meanings and activation of promoter signs or, in other words, to the dialogical dynamics between I-positions. In this respect, we suggest that the assumption of a more dialogic and semiotic lens could be an interesting further development to this study

The social cognition of medical knowledge, with special reference to childhood epilepsy

This paper arose out of an engagement in medical communication courses at a Gulf university. It deploys a theoretical framework derived from a (critical) sociocognitive approach to discourse analysis in order to investigate three aspects of medical discourse relating to childhood epilepsy: the cognitive processes that are entailed in relating different types of medical knowledge to their communicative context; the types of medical knowledge that are constituted in the three different text types analysed; and the relationship between these different types of medical knowledge and the discursive features of each text type. The paper argues that there is a cognitive dimension to the human experience of understanding and talking about one specialized from of medical knowledge. It recommends that texts be studied in medical communication courses not just in terms of their discrete formal features but also critically, in terms of the knowledge which they produce, transmit and reproduce

When climate science became climate politics: British media representations of climate change in 1988

Climate change has become a pressing environmental concern for scientists, social commentators and politicians. Previous social science research has explored media representations of climate change in various temporal and geographical contexts. Through the lens of Social Representations Theory, this article provides a detailed qualitative thematic analysis of media representations of climate change in the 1988 British broadsheet press, given that this year constitutes an important juncture in this transition of climate change from the domain of science to that of the socio-political sphere. The following themes are outlined: (i) “Climate change: a multi-faceted threat”; (ii) “Collectivisation of threat”; (iii) “Climate change and the attribution of blame”; and (iv) “Speculative solutions to a complex socio-environmental problem.” The article provides detailed empirical insights into the “starting-point” for present-day disputes concerning climate change and lays the theoretical foundations for tracking the continuities and discontinuities characterising social representations of climate change in the future
