The characterization of the products of international cooperation as public goods has been severely challenged, undermining a central pillar of theories of international cooperation. I review the criticism of public goods assumptions, identifying the need to account for both exclusion and rival consumption in international cooperative arrangements. Drawing on the recent debate of states as relative versus absolute gains maximizers, I offer a characterization of international cooperative arrangements as discriminatory clubs. I develop a refined relative gains model, which focuses on relative net gains, and apply it to a hypothetical situation to illustrate its usefulness in predicting patterns of exclusion and distribution in international trade. 相似文献

Charles Edouard Brown-Séquard used observation of recovered patients and experimental animals to support his theory of cerebral localization. Recovery theories assume that the nervous system is composed of one organ or many, and that each organ has one function or many. From his own studies as well as others, Brown-Séquard concluded that the brain contained at least nine separate organs, each with a single distinct function, and that each organ is organized, not as a geographically isolated cluster of neurons, but as a widely disseminated network. According to his view, function is not uniformly distributed in an organ. Focal necrosis of part of an organ temporarily inhibits the action of distant, undamaged parts; resolution of this inhibition results in recovery. Using this theory of cerebral localization and recovery, Brown-Séquard practiced an early form of scientific neurology. 相似文献

This paper summarizes recent archaeological research efforts, and changing perspectives, about the native history of the Caddo peoples who lived in the Caddoan Archaeological Area, which centers on the Great Bend of the Red River in Oklahoma, Texas, Arkansas, and Louisiana. Of particular focus are the origins and early developments of the Caddoan tradition, regional diversity, subsistence changes and agricultural intensification, sociopolitical dynamics, and Caddoan-European interaction. 相似文献

Much practically orientated environmental research is marked by a polarity between functionalist abstraction and ahistorical normative discourse. This paper seeks to bridge the divide between theoretical and empirical research through a case study of New York City's water supply. Current processes of socio-economic restructuring are leading to negative environmental consequences obscured by a failure to extend analysis beyond limited temporal, spatial or sectoral scales. Insights from regulationist theory show that a combination of fiscal, political and other developments are bringing about a wide-ranging reformulation of existing patterns of environmental regulation and service provision in the city. The power of the state is being radically diminished in relation to the power of capital and a plethora of different interest groups. A relatively simple centralized model of environmental regulation is being transformed into a complex decentralized pattern involving the emergence of new approaches to urban governance. Further research is needed on the contradictions between capitalist accumulation and environmental regulation at different spatial scales in order to link New York's changing role within the global economy to the declining political legitimacy and fiscal capability of the state to play an extensive role in environmental management. 相似文献

This paper is an attempt to provide an organizing framework for understanding geographic (and related) research that deals with modern social control. The basic panoptic logic of what Foucault termed disciplinary power can be understood to operate at a variety of scales, from that of buildings to that of national territories. But the particular way in which disciplinary power plays out, the way in which the logic of visibility interacts with other forms of power, varies systematically with scale and context. Thus I offer a more scale- and context-sensitive typology of "disciplines", and the bulk of the essay is devoted to explaining the categories of this typology with reference to existing research. The larger purpose of this paper is to improve our understanding of how modern social control is bound up with larger socio-spatial relations. 相似文献

Following in the wake of Benedict Anderson's work in particular, cultural geographers and cultural studies scholars have analyzed the nation and nationalism as primarily 'imagined' or abstract entities. Coincidentally, the greatest analytic attention has been given to nationalist representations of place, rather than to the everyday discursive practices constitutive of the nation as lived. Drawing on Pierre Bourdieu's practice theory, in this paper I develop the beginnings of a corporeal approach to the nation. Here the relationship between the practice of identity (the embodiment of gendered and sexualized subjectivities via discursive practice within culturally defined spaces) and an Irish nationalist sense of place is explored. In this approach, analytic considerations of identity and space are collapsed within the shared material and metaphoric medium of the body. Irish nationalism and the nation are analyzed as corporeal materialities via an ethnohistorical focus on late nineteenth-century changes in the political economy of 'peasant' and nationalist bodies. The analysis suggests that a particular matrix of constructions of femininity and masculinity was extended paradigmatically throughout the society in the latter half of the nineteenth century. These paradigmatic changes are characterized as a 'heterosexing' of bodies and places linked to economic change and the rise of the confessional state. 相似文献
