The conventional model of the relationship between welfare incentives and poverty rates holds that welfare payments produce an income-enhancement effect that removes families from poverty until some threshold. Beyond this point increased payments engender a work-disincentive effect resulting in increased rates of poverty. We challenge the model's assumption that poverty levels are a simple and spatially invariant response to welfare incentives, contending instead that local employment conditions may substantially alter the relation. Our reformulation of the conventional modeling approach is based on the expansion method. Specifically, we extend the model to include the effects of local labor-market conditions on the response of poverty levels to welfare incentives. In contesting the invariance assumption, the expansion method allows us to determine where and in what contexts welfare is “work discouraging.” The empirical analysis, which is undertaken at the county level, indicates that welfare payments vary in their influence on poverty rates across different employment contexts. A national map portraying this parameter instability demonstrates that female-family poverty rates are most responsive to welfare assistance in the rural South and least responsive in the metropolitan Northeast. Finally, we examine two sharply contrasting locales to illustrate how poverty is governed by specific employment and welfare characteristics.  相似文献

Abstract. German society is on its way to changing from a relatively homogenous population as a result of the Second World War and prior events to a more culturally, ethnically and religiously diverse society, based on its huge post-war immigration. The emergence of racism, political extremism and violence in post-unification German society points to deficits of political legitimacy, political culture and social cohesion. The strains of unification and waves of immigration from East Germany, ethnic German resettlers (Aussiedler), and asylum seekers have exacerbated and made visible unsolved questions of national identity, diversity, immigration and integration of foreigners. These events have affected German political culture and polarised the traditional party system along a ‘New’ and ‘Old Politics’ axis. These new realities have led to a growth of far right parties, racist violence, and an increase of neo-nationalist, anti-immigrant and welfare-chauvinist rhetoric.  相似文献

Arthur C. Danto has long defended essentialism in the philosophy of art, yet he has been interpreted by many as a historicist. This essentialism/historicism conflict in the interpretation of his work reflects the same conflict both within his thought and, more importantly, within modern art itself. Danto's strategy for resolving this conflict involves, among other things, a Bildungsroman of modern art failing to discover its essence, an essentialist definition of art provided by philosophy which is indemnified against history, and a thesis about the end of art once it has been defined. Is this strategy successful, or does it result, as I argue, in a philosophical disenfranchisement of art of precisely the type that Danto himself has criticized?  相似文献
