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
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
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
Global inequality, human rights and power: a critique of Ulrich Beck's cosmopolitanism
This article is a critique of Ulrich Beck's advocacy of a cosmopolitan approach to global inequality and human rights. It is argued that cosmopolitanism does not bring a new and unique perspective on global inequality. In fact Beck's proposals on migration would reinforce inequality and anti-cosmopolitanism. It is argued that his `both/and' perspective on hybridization and contextual universalism is undermined by inequality, conflict and power that are glossed over in Beck's approach. I argue that human rights interventionism as advocated by Beck falls short of cosmopolitanism, in ways which are shown by qualifications about power and inequality that Beck himself makes in his arguments
The Football Supporter in a Cosmopolitan Epoch
Arguably, the later process of globalization served to reshape how socializations are fostered and maintained across time and space. Additionally, in the last fifteen years a new phenomenon that reinvigorated time and space compression has emerged: social media. Moreover, it is argued that the conjunction of those processes can be seen as taking place on a distinct Age - the Anthropocene or the cosmopolitan epoch. Arguably those processes have the capacity to alter the way individuals enact their football fandom In this light, this paper seeks to conceptualize one particular football support identity that takes into account this fragmented period. Based on an 18-month ethnographic research with supporters of one English Premier League, this paper conceptualizes the football fan in the Anthropocene as the cosmopolitan flĂąneur. I conclude by pointing out to some prospective avenues for future research based on a cosmopolitan imagination
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
