Pierre Marie was a prominent member of the French neurological world of the early twentieth century. Having been trained by the celebrated physician, J-M Charcot, Marie remained influenced by his teacher throughout his career. Because of this influence, his career can be logically divided into three phases: first, the early years under the direct mentorship of Charcot (1878-1893); secondly, the aftermath of Charcot's death when Marie left his teacher's institution, the Salpêtrière hospital and established himself at the Bicêtre hospital in southern Paris (1893-1918); and finally, Marie's return to the Salpêtrière to assume the original Charcot chaired professorship, albeit as an aged man (1918-1925). This essay examines Marie's career with an emphasis on documentation of the combined attributes of a gifted intellect as well as a heated emotionality. In the context of his time, these elements prompted Marie to enter into controversies and medico-political battles that advanced neurological knowledge, but likely disadvantaged him in his career successes.  相似文献

The deepwater part of the Gulf of Mexico has shown a remarkable increase in oil and gas exploration, development, and production. In part, this is because of the development of new technologies reducing operational costs and risks, as well as the finding of reservoirs with high-production wells. With expanding development in deep water come increasing challenges in managing our nation’s Submerged Cultural Heritage on the Outer Continental Shelf and Slope. To fulfill obligations under Section 106 of the Historic Preservation Act of 1966 (36 CFR 800), managers need a clearer understanding of the size of debris fields expected around deepwater shipwrecks, as well as their state of preservation and future research potential—both cultural and biological. With this in mind, the Minerals Management Service, in partnership with the National Oceanographic Partnership Program and the National Oceanographic and Atmospheric Administration’s Office of Ocean Explorations, launched the Deep Gulf Wrecks Project.  相似文献

ABSTRACT We consider the problem of integrating spatial amenities into locational equilibrium models with multiple jurisdictions. We provide sufficient conditions under which models that assume a single housing price in each community continue to apply in the presence of location‐specific amenities that vary both within and across communities. If these conditions are satisfied, the models, estimation methods, and results in Epple and Sieg (1999) are valid in the presence of (potentially unobserved) location‐specific amenities. We also show how to construct sufficient statistics that capture location specific spatial heterogeneity. We apply these techniques using data from the Pittsburgh metropolitan area. We find that these amenity measures capture proximity to important local employment centers as well as heterogeneity in school quality within a given school district.  相似文献

This paper contributes to a burgeoning body of literature which seeks to highlight the importance of studying small cities. Dissatisfaction with urban theory dominated by study of ‘the city’ defined in terms of a small number of ‘global’ cities has led theorists to consider what is lost as a consequence of this bias. Although there is long way to go to challenge the orthodoxies of urban theory dominated by study of the ‘biggest and best’, here we focus on an area of small cities research where progress has been made towards developing a more inclusive agenda. This study reviews research into the cultural economy of small cities and highlights a growing body of rich and detailed literature. Despite this progress, however, we argue that a coherent and clear research agenda is yet to emerge. To this end, we signpost ways in which bolder theoretical and empirical questions can be developed that can begin to make more of a significant impact on urban theory.  相似文献

The article examines the first official, national Holocaust memorial day in Italy, the so-called Giorno della memoria (Day of memory), marked on the 56th anniversary of the liberation of Auschwitz on 27 January 2001. It looks at the ways in which the day acted as a filter for issues of national collective memory and identity, in particular state and public negotiation of the legacy of Fascism, as well as addressing broader issues of Holocaust remembrance. The article looks first at the origins of the Giorno della memoria in political and in legislative terms. Then it sketches in the events of the day itself, at national and local levels, in political, educational and cultural terms. This is followed by an analysis of media coverage and contemporary commentary, showing how various lines of interpretation addressed general issues related to the Holocaust and specifically Italian historical, ideological and contemporary questions.  相似文献

This article offers an account of a recent debate in the cultural pages of the Italian press on a polemical work of literary criticism entitled Pasolini contro Calvino, in which the two authors are shown to represent emblematically different attitudes towards literature, cultural institutions and the culture industry in post‐war Italy. The debate surrounding this claim is examined in substance, but also as an illustration of the workings of culture in 1990s Italy.  相似文献

Historians have long relegated colonialism to the margins of modern Spanish history. Spain lost the majority of its overseas empire in the Spanish American revolutions of the early nineteenth century. It was a late, reluctant, and small‐scale participant in the partition of Africa. Recent scholarship, however, is bringing colonialism back to the center of Spain's nineteenth and twentieth centuries. This article examines these findings and considers their consequences for narratives of Spanish marginality and modernity. Special attention is given to two recent works: John Tone's War and Genocide in Cuba and Sebastian Balfour's Deadly Embrace.  相似文献
