All Killing Superalgebras for Warped AdS Backgrounds
We present all the symmetry superalgebras of all warped
AdS, , flux backgrounds in dimensions
preserving any number of supersymmetries. First we give the conditions for
to decompose into a direct sum of the isometry algebra of
AdS and that of the internal space . Assuming this decomposition,
we identify all symmetry superalgebras of AdS backgrounds by showing that
the isometry groups of internal spaces act transitively on spheres. We
demonstrate that in type II and theories the AdS symmetry
superalgebras may not be simple and also present all symmetry superalgebras of
heterotic AdS backgrounds. Furthermore, we explicitly give the symmetry
superalgebras of AdS, , backgrounds and prove that they are all
classical.Comment: 41 pages, late
The social, cosmopolitanism and beyond
First, this article will outline the metaphysics of âthe socialâ that implicitly and explicitly connects the work of lassical and contemporary cosmopolitan sociologists as different as Durkheim, Weber, Beck and Luhmann. In a second step, I will show that the cosmopolitan outlook of classical sociology is driven by exclusive differences. In understanding human affairs, both classical sociology and contemporary cosmopolitan sociology reflect a very modernist outlook of epistemological, conceptual, methodological and disciplinary rigour that separates the cultural sphere from the natural objects of concern. I will suggest that classical sociology â in order to be cosmopolitan â is forced (1) to exclude non-social and non-human objects as part of its conceptual and methodological rigour, and (2) consequently and methodologically to rule out the non-social and the non-human. Cosmopolitan sociology imagines âthe socialâ as a global, universal explanatory device to conceive and describe the non-social and non-human. In a third and final step the article draws upon the work of the French sociologist Gabriel Tarde and offers a possible alternative to the modernist social and cultural other-logics of social sciences. It argues for a inclusive conception of âthe socialâ that gives the non-social and non-human a cosmopolitan voice as well
The paths not (yet) taken: Ulrich Beck, the âcosmopolitized worldâ and security studies
Ecological study of aquatic midges and some related insects with special reference to feeding habits
Die Schweiz ist ein reiches Land. Sie verfĂŒgt ĂŒber viele MillionĂ€re. Der groĂe Reichtum konzentriert sich auf wenige Familien und Personen. In der Schweiz leben aber auch eine halbe Million der Bevölkerung (7,5 Mio.) in Haushalten von ErwerbstĂ€tigen, die weniger als das Existenzminimum verdienen. Ăber 200â000 Personen sind auf Sozialhilfe angewiesen. Bei den Vermögen und den verfĂŒgbaren Einkommen hat sich in den letzten Jahren die Kluft zwischen den obersten und untersten zehn Prozent verschĂ€rft. Die Zunahme der sozialen Ungleichheit erhöht die soziale Brisanz, was mehr zu ergrĂŒnden ist. Die soziale Differenzierung dokumentiert Prozesse der Globalisierung. Sie reproduziert und spezifiziert alte soziale Ungleichheiten. Wichtig ist, dass die Soziale Arbeit das thematisiert und weiter theoretisiert
In good company: risk, security and choice in young people's drug decisions
This article draws on original empirical research with young people to question the degree to which 'individualisation of risk', as developed in the work of Beck and Giddens, adequately explains the risks young people bear and take. It draws on alternative understandings and critiques of 'risk' not to refute the notion of the reflexive individual upon which 'individualisation of risk' is based but to re-read that reflexivity in a more hermeneutic way. It explores specific risk-laden moments â young people's drug use decisions â in their natural social and cultural context of the friendship group. Studying these decisions in context, it suggests, reveals the meaning of 'risk' to be not given, but constructed through group discussion, disagreement and consensus and decisions taken to be rooted in emotional relations of trust, mutual accountability and common security. The article concludes that 'the individualisation of risk' fails to take adequate account of the significance of intersubjectivity in risk-decisions. It argues also that addressing the theoretical overemphasis on the individual bearer of risk requires not only further empirical testing of the theory but appropriate methodological reflection
Visions in monochrome: Families, marriage and the individualisation thesis
This paper takes issue with the way in which the individualisation thesis â in which it is assumed that close relationships have become tenuous and fragile - has become so dominant in ânewâ sociological theorising about family life. Although others have criticised this thesis, in this paper the main criticism derives from empirical research findings carried out with members of transnational families living in Britain whose values and practices do not fit easily with ideas of individualisation. It is argued that we need a much more complex and less linear notion of how families change across generations and in time
When the working day is through: The end of work as identity?
This article seeks to present a counter-case to the âend of work thesisâ advocated by writers such as Beck, Sennett and Bauman. It argues that work remains a significant locus of personal identity and that the depiction by these writers of endemic insecurity in the workplace is inaccurate and lacks empirical basis. The article draws upon case study data to illustrate how, across a range of workplaces, work remains an importance source of identity, meaning and social affiliation
