This article explores a particular moment in the history of Toronto's gay movement politics when the movements' ideological perspectives on the nature of gay and lesbian identities and associated spaces shifted dramatically from the so-called liberationist stance of the mid-1970s to the so-called ethnic minority approach of the late 1970s. This occurred within the context of a particular series of events that prompted gay activists to rework their conceptualization of gay and lesbian identity in order to be recognized as legitimate participants in certain pivotal, public proceedings. Far from being a well-thought-out and deliberate shift in political strategy, the ‘minority’ argument was, in many ways, a reflexive and unexamined response to unanticipated circumstances. Toronto's gay activists, in representing gays and lesbians as a minority fundamentally altered meanings associated with both gay and lesbian identities and with the spaces dominated or controlled by gay and lesbian interests.

Este artículo explora un momento particular en la historia de las políticas del movimiento de los gays de Toronto cuando sus perspectivas ideológicas sobre la naturaleza de identidades gay y lesbiana y sus espacios respectivos cambiaron dramáticamente, desde la llamada ‘perceptiva liberacionista’ de los mediados de los años setenta hasta la llamada ‘perspectiva de las minorías étnica’ de los últimos años de los setentas. Esta cambio ocurrió dentro del contexto de una serie particular de eventos que incitaron a los activistas gay a revisar sus conceptualizaciónes sobre su identidad gay y lesbiana con el fin de ser reconocidos como participantes legítimos en ciertos procesos públicos. Lejos de ser un cambio bien planeado y deliberado en la estrategia política, el argumento de la ‘minoría’ consistía, de varios maneras, en una repuesta no reflexiva no examinada a circunstancias inesperadas. Los activistas gay de Toronto, al representar a los gays y lesbianas como minorías, alteraron de manera fundamental los significados asociados tanto a las identidades de gays y lesbianas como los espacios dominados o controlados por intereses de gays y lesbianas.  相似文献

The recent passage of the Americans with Disabilities Act and other pieces of legislation affecting the disability community and other civil rights communities suggests a level of cohesion within the disability movement that blurs the reality and the power of the tensions which did and do exist. Examining the struggles to maintain an effective, cohesive entity provides an opportunity to explore the complexity of the disability movement as well as lessons for policy and program planning and for community organizing.  相似文献

Spatial Cluster Detection in Spatial Flow Data   总被引:2,自引:0,他引:2       下载免费PDF全文
As a typical form of geographical phenomena, spatial flow events have been widely studied in contexts like migration, daily commuting, and information exchange through telecommunication. Studying the spatial pattern of flow data serves to reveal essential information about the underlying process generating the phenomena. Most methods of global clustering pattern detection and local clusters detection analysis are focused on single‐location spatial events or fail to preserve the integrity of spatial flow events. In this research we introduce a new spatial statistical approach of detecting clustering (clusters) of flow data that extends the classical local K‐function, while maintaining the integrity of flow data. Through the appropriate measurement of spatial proximity relationships between entire flows, the new method successfully upgrades the classical hot spot detection method to the stage of “hot flow” detection. Several specific aspects of the method are discussed to provide evidence of its robustness and expandability, such as the multiscale issue and relative importance control, using a real data set of vehicle theft and recovery location pairs in Charlotte, NC.  相似文献

Climate engineering, or geoengineering, refers to large-scale climate interventions to lower the earth's temperature, either by blocking incoming sunlight or removing carbon dioxide from the biosphere. Regarded as ‘technofixes’ by critics, these strategies have evoked concern that they would extend the shelf life of fossil-fuel driven socio-ecological systems for far longer than they otherwise would, or should, endure. A critical reading views geoengineering as a class project that is designed to keep the climate system stable enough for existing production systems to continue operating. This article first examines these concerns, and then goes on to envision a regime driven by humanitarian agendas and concern for vulnerable populations, implemented through international development and aid institutions. The motivations of those who fund research and implement geoengineering techniques are important, as the rationale for developing geoengineering strategies will determine which techniques are pursued, and hence which ecologies are produced. The logic that shapes the geoengineering research process could potentially influence social ecologies centuries from now.  相似文献

A specialist on financial issues in the State of Bosnia and Herzegovina assesses economic performance in that country during the five years following conclusion of the Dayton Peace Accords. The basic provisions of the Accords relating to economic activity and post-war reconstruction are presented, after which the analysis focuses on developments in the economy, privatization, and banking-sector reform, to the extent that available data allow. Coverage then turns to a review of the role of the Office of the High Representative in administration of the State's two constituent Entities: the Federation of Bosnia-Herzegovina and the Serb Republic.
