Under German colonial rule and the British mandate, Dar es Salaam was a racially segregated city. The means of segregation were a series of building ordinances that established varying standards of construction in the city's neighborhoods. A result of these ordinances was the concentration of expatriates—those people living outside their home country—in two areas of the city: the City Center and the Msasani Peninsula. Using qualitative survey and interview data with fifty expatriates in contemporary Dar es Salaam, this paper demonstrates that segregation persists in spite of postcolonial efforts to desegregate the city. In fact, segregation in contemporary Dar es Salaam affects more than just residential patterns; all aspects of expatriate everyday life are overwhelmingly concentrated in these two urban areas. This paper engages with colonial city and expatriate literatures to identify the lingering effects of colonialism and the various ways that residents perceive and transform urban space. Several explanations exist for the persistence of this segregation. These two areas historically housed expatriates and thus contain desirable urban amenities such as supermarkets and shopping malls. These areas also offer expatriates the comfort of living among other expatriates in a perceived safe environment. 相似文献

Abstract: The environmental justice movement has highlighted not only the unequal distribution of environmental hazards across lines of race and class, but also the white, middle‐class nature of some environmentalisms, and broader patterns of marginalization underlying people's opportunities to participate or not. There is a significant body of work discussing Hispanic environmental justice activism in the US, but not in Canada. This paper draws on interviews with representatives of organizations working on environmental initiatives within the Hispanic population of Toronto, Canada to explore definitions of and approaches to environmentalism(s) and community engagement. Four interrelated “mechanisms of exclusion” are identified in this case study—economic marginalization; (in)accessibility of typical avenues of participation; narrow definitions of “environmentalism” among environmental organizations; and the perceived whiteness of the environmental movement. Taken together, these mechanisms were perceived as limiting factors to environmental activism in Toronto's Hispanic population. We conclude that the unique context of Toronto's Hispanic community, including contested definitions of “community” itself, presents both challenges and opportunities for a more inclusive environmentalism, and argue for the value of “recognition” and “environmental racialization” frameworks in understanding environmental injustice in Canada. 相似文献

Dar es Salaam, Tanzania, has a long history as a segregated city. Starting in 1891 the German and then later the British colonial government enacted a series of building ordinances that outlined the styles of construction allowed within different areas of the city. Although these policies applied only to the structures themselves, ultimately they served to divide the city into European/Expatriate, Asian, and African areas. In spite of official attempts to integrate the city, postcolonial Dar es Salaam remains a racially segregated place. This segregation extends beyond residence location and affects all aspects of everyday life such as shopping and recreation. This article uses mental maps drawn by some of Dar es Salaam's residents to illustrate the lingering effects of colonial segregation on the knowledge, perception, and experiences residents have in and of today's city. Expatriate, Asian, and African maps include vastly different locations within the city. Those places considered important enough to map demonstrate that colonialism has continued impacts on the spaces and realities of everyday life in contemporary Dar es Salaam. 相似文献

For five decades it has been generally accepted that reserpine, an antihypertensive and antipsychotic drug, causes depression. The discovery that reserpine depletes brain monoamines was an important factor in the development of the monoamine hypothesis of depression, and it continues to be widely cited in support of this hypothesis. The present paper argues that, contrary to prevailing belief, reserpine is not depressogenic. The reason for perpetuation of this myth is reluctance to discard the monoamine hypothesis. This hypothesis ushered the modern biochemical paradigm into psychiatry and is still of great importance. It serves as a heuristic to guide research, it enhances psychiatry’s prestige, and it helps to validate and promote drug therapy for depression and other mental disorders. 相似文献
