During the past decade research into the German Final Paleolithic and Mesolithic has experienced an important revival. One clear sign of this renewed interest in the periods are the annual meetings of the Arbeitsgruppe Mesolithikum (Mesolithic Working Group) which have taken place every spring since 1992. At these meetings, which take place at changing venues, topical themes of Final Paleolithic and Mesolithic interest are presented by informal lectures and it is also possible to study regional collections (artifacts, raw materials) at first hand. Numerous contributions were subsequently published together in one volume (Conard and Kind (1998) Aktuelle Forschungen zum Mesolithikum/Current Mesolithic Research, Mo Vince, Tübingen). The present paper intends to complement that collection of papers with a synthesis of developments and perspectives and to present recent research highlights in the German Final Paleolithic and Mesolithic, together with a comprehensive bibliography, to a wider international audience. 相似文献

Testing for the Law of One Price and Identifying Price-Leading Markets: An Application to Corn Markets in Benin 总被引:1,自引:0,他引:1
A data-determined method is proposed to test for the law of one price as a long-run equilibrium condition and to identify which markets in a network of spatially dispersed commodity markets quote the reference price. The method consists of supplementing Johansen's FIML cointegration procedure with a permanent-transitory decomposition and rules of inference in linear time-series models with unit roots. As an example, we apply our method to prices of six corn markets in Benin. We find that the law of one price holds in the long-run. It appears that two rural markets quote the reference price: their prices adjust fastest towards the permanent change induced by the common stochastic trend. 相似文献

The new imperial history has advanced our understanding of empires in many ways: it enhanced a networked interpretation of empires, brought space back into the discussion, and suggested a fresh reading of imperial careers to comprehend early forms of global inter-dependencies. This article discusses selected aspects of the life and work of Benoy Kumar Sarkar (1887–1949), a Bengali social scientist and political activist, to illustrate that anti-imperial biographies were simultaneously rooted in local as well as transnational spaces. They thus connected national struggles with globe-spanning processes. Biographies like this are underacknowledged in their meaning for how empires functioned and failed, and in their potential for understanding transnational actors. Sarkar’s efforts to challenge the legitimacy of the British Empire were the result of his life in a transnational social field, which was equally shaped by his extensive experience abroad and his continuous rootedness in local Bengali affairs. Sarkar’s anti-imperialism was enhanced by the mobility structures of the British Empire and resulted in new constellations of imperial, cosmopolitan, local and regional orientations and attachments. In this view, anti-imperialism was less the result of local struggles but of life practices reaching beyond the borders of the empire and a high awareness of acting in a global context that located its protagonists in numerous social and spatial contexts. 相似文献

In the present article, the impact of both near fault ground motions and a finite ductility threshold on the collapse capacity is studied. Single-degree-of-freedom systems with non-deteriorating bilinear hysteretic behavior, vulnerable to P-delta effects, are considered. Defining collapse as excessive ductility is investigated, and the difference to collapse associated with instability is elaborated. Medians of individual record dependent collapse capacities are presented as function of the initial structural period for characteristic structural and ground motion parameters. Analytical expressions for influence coefficients, which account for a differing ground motion set, and finite ductility thresholds, respectively, are derived via non-linear regression analysis. 相似文献
