    The Gibbs Paradox Revisited

    Full text link
    The Gibbs paradox has frequently been interpreted as a sign that particles of the same kind are fundamentally indistinguishable; and that quantum mechanics, with its identical fermions and bosons, is indispensable for making sense of this. In this article we shall argue, on the contrary, that analysis of the paradox supports the idea that classical particles are always distinguishable. Perhaps surprisingly, this analysis extends to quantum mechanics: even according to quantum mechanics there can be distinguishable particles of the same kind. Our most important general conclusion will accordingly be that the universally accepted notion that quantum particles of the same kind are necessarily indistinguishable rests on a confusion about how particles are represented in quantum theory.Comment: to appear in Proceedings of "The Philosophy of Science in a European Perspective 2009

    Wage Inequality and the Changing Organization of Work.

    This paper sheds light on how changes in the organization of work lead to wage inequality. We present a theoretical model in which workers with a wider span of competence (higher level of multitasking) earn a wage premium. Since abilities and opportunities to expand the span of competence are distributed unequally among workers across and within education groups, our theory explains (1) rising wage inequality between groups, (2) rising wage inequality within groups, and (3) the polarization of work and the decoupling of the income distribution. Using a rich German data set covering a 20-year period from 1986 to 2006, we provide empirical support for our model.

      Föreliggande rapport Ă€r en granskning av det statliga betĂ€nkande som görs i samband med de hĂ€ndelser som Ă€ger rum vid EU-mötet i Göteborg Ă„r 2001. Syftet Ă€r att analysera kommittĂ©ns slutsatser och förslag utifrĂ„n en vetenskaplig studie av dessa hĂ€ndelser de s.k. Göteborgskravallerna som görs pĂ„ institutionen för beteendevetenskap vid Linköpings Universitetet. I likhet med internationell forskning visar Linköpingsstudien att kravaller kan ses som ett resultat av vĂ€xelverkande processer mellan polis och demonstranter vilka antingen kan leda till krig eller fred. Demonstranter utgör frĂ„n början inte en homogen "massa" utan bestĂ„r av mĂ„nga olika grupperingar av vilka s.k. postmoderna demonstranter urskiljer sig som en specifik kategori. Eftersom de skiljer sig frĂ„n traditionella demonstranter i olika avseenden riskerar de att kategoriseras och behandlas som tillhöriga en fientligt instĂ€lld provokatörsgrupp. I rapporten visas bl.a. att kommittĂ©n bygger sina förslag pĂ„ en onyanserad uppdelning av demonstrationer i en fredlig (modern) grupp och en fientlig provokatörsgrupp och dĂ€rmed missar frĂ„gan om hur man kan möta en ny rörelse av politiskt intresserade ungdomar inom ramen för ett demokratiskt samhĂ€lle
