ABSTRACT. Cosmopolitanism has emerged as a humanistic perspective to express globalizing societal experiences. What are its geographies? World cities are centers of globalizing processes, and their populations and institutions may share elements of cosmopolitical worldviews. Most world cities have also been ports, yet in the contemporary global imaginary, many world cities are not readily understood as places of maritime activity, historic or contemporary. Disjunctures in perceptions of the coastal city-region reflect changes in the world economy and human experiences in modes of travel. This analysis recovers geographical processes of maritime urban areas as a basis for understanding transhistorical and geographical factors of cosmopolitics in globalizing regions and contemporary intellectual thought.  相似文献

随着昆明市城市化进程的加快和行政区划的重新调整,城市辐射功能增强,城市空间急剧扩展,使原来的城市边缘区域为中心区所包围,形成大片“城中村”。昆明市“城中村”改造涉及范围广、数量大、人口多,缺少可以置换的土地,改造成本巨大。以昆明市最大的“城中村”——东庄村改造为个案,通过实地调查、访谈和文献法,分析昆明市“城中村”的现状、问题和成因,并认为应尽快分阶段进行改造。在改造中,应从昆明市目前的社会经济情况出发,根据不同类型,选择实施以开发商为主体和以村民为主体的不同改造模式。同时,政府应加强监督与协调,尽早制定“城中村”改造的地方政策和法规,编制统一、科学的规划,积极协调和平衡村民、村集体和开发商之间的利益冲突,保护村民的利益不受侵害,并通过职业培训、社区服务、社会保障等措施解决村民的生计,转变他们的思想观念、生活方式,使其真正融入现代社会。  相似文献

ABSTRACT. Since the late 1990s Wilbur Zelinsky's theory of “heterolocalism’ has provided human geographers and other social scientists with a new approach to analyzing the spatial patterns and ethnic identities of recent immigrants in the United States. Zelinsky's heterolocal model suggests that, to a degree unknown in the past, new migrants in North American cities may choose to settle in widely dispersed places, rather than in more concentrated ethnic enclaves, while maintaining their ethnic identities. This article expands on and critiques prior work on heterolocalism in Oregon by examining the spatial patterns, ethnic and religious identities, and transnational relationships of two recent refugee groups in three urban areas in the Pacific Northwest. Using data from U.S. and Canadian census records, refugee resettlement agency files, survey questionnaires, structured and unstructured interviews, and participant observation with post‐Soviet Russians and Ukrainians in the Vancouver, British Columbia, Seattle, Washington, and Portland, Oregon metropolitan areas, I analyze the spatial patterns and related social networks that define the identities and residential and religious spaces of these groups to test the efficacy of relating heterolocalism and transnationalism across an international boundary.  相似文献

ABSTRACT. Environmental narratives in Africa have been examined in a flurry of publications since the mid‐1990s. In this article we seek to offer insights into the role and motivations of volunteer development workers in perpetuating environmental narratives. We examine the factors that led to the questioning or nonquestioning of environment‐development discourses and their influence, if any, on the actual work undertaken by volunteers. As former development volunteers, we also explore the role that the development‐volunteer experience subsequently played in shaping our own research as academics. Our analysis is based largely on our tenure as U.S. Peace Corps volunteers in Mali from 1987 until 1989 and our later experiences as academics. We draw on our memories, interviews with former colleagues, and training materials to describe how volunteers were introduced to, and encouraged to act on, environmental problems in the West African Sudano‐Sahel. We adopt a reflexive approach to explore briefly how our experiences as volunteers influenced our research and writing as academics.  相似文献

ABSTRACT. Rural private lands in the Mountain West of the United States are undergoing a profound land‐use conversion, from agriculture to low‐density residential or exurban development, though little scientific study documents the ecological consequences of this change. Nongovernmental conservation organizations are working with ranchers to keep rangeland out of development and in ranching, ostensibly because these organizations believe that biodiversity is better protected on ranches than on exurban developments. We compared plant and wildlife communities across the principal rural land uses in the Mountain West: protection, livestock ranching, and exurban development. Native plant and faunal biodiversity was better maintained on ranches and protected areas than on exurban developments. Exurban developments favored species that were nonnative or adapted to human‐altered environments. The continued conversion of ranches to exurban development suggests a long‐term alteration of the region's natural heritage.  相似文献

ABSTRACT. In the lead‐up to the World War I Paris Peace Conference the United States convened The Inquiry‐a group of leading scholars‐to propose equitable terms, including new borders, for the final peace settlements. In many areas throughout Europe, among them Transylvania, coming to a settlement that fully accounted for Woodrow Wilson's principle of self‐determination proved difficult. Hungary's populace comprised many nationalities, some very hostile toward Romania, the state that eventually acquired the entire region. In this article I analyze how the American plan differed from that finally adopted at the conference and how closely The Inquiry's plan for Transylvania followed the principles laid out by President Wilson in his famous “Fourteen Points,” which provided the basis for American participation in World War I. The ethnic mix within Transylvania made it an especially difficult region in which to apply Wilsonian principles.  相似文献

Located near the southeastern limit of Africa, the Lesotho‐Drakensberg and associated escarpment is the highest range of African mountains south of the massifs in Tanzania. At the escarpment summit and on the adjacent high peaks, the climate is generally interpreted as marginal periglacial yet few data, specifically rainfall and temperature, exist on record at these altitudes. Climatic data from two temporary field stations on the escarpment edge, one of which is the highest rainfall station yet on record in southern Africa, provide contemporary surface‐climate conditions. Mean annual rainfall recorded between 2001 and 2005 averages 767.8 mm at Sani Pass summit (three complete years), and 753.2 mm on Sentinel Peak (two complete years); these values are less than those recorded for the same period in the mountain foothills. Even though rainfall is slightly below long‐term rainfall averages for the area due to a marginally dry spell, the data show that earlier estimates of between 1000 mm and 2000 mm rainfall per annum on the escarpment are too high. A measured mean air temperature of 5.8°C at Sani Pass, however, falls within the range estimated for the escarpment summit. Frost cycles in air and at the soil surface are frequent in winter, but absent in soil for summer, and no long‐duration surface‐soil freeze was measured. Temperatures thus confirm the marginal periglacial nature as postulated for previously, but precipitation data indicate a dryer environment than anticipated. Palaeoenvironmental scenarios, notably arguments for former glaciation based on extrapolations from somewhat exaggerated contemporary precipitation values, thus require re‐consideration.  相似文献

ABSTRACT. Many mountain peoples face water and environmental health problems. At particular risk is the health of women and of children who live in remote and marginalized mountain areas. Environmental health concerns are often associated with the waterborne parasitic and endemic diseases responsible for much child morbidity and mortality in the Karakoram‐Himalaya of northern Pakistan. Poor environmental health and water‐quality conditions affect child survival, and challenges to viable local interventions are severe. Transformations in women's productive and reproductive work have health consequences for children, and gender and household dynamics shape and mediate women's responses to environmental health risks. Significantly, these findings draw attention to the need for improved water and health policy, especially policy that recognizes different gender and child‐care roles in mountainous regions of the developing world.  相似文献

ABSTRACT. This article analyzes New Zealand's rights‐based system of fisheries management from the perspective of local stakeholders on northern Great Barrier Island. The research identified differing perspectives through use of the concept of “boundary construction,” not only in terms of society and nature but also among societal institutions. Great Barrier Island participants exhibited significant differences, especially between staff of the local Department of Conservation and local Maori, both of whom were engaged in negotiating policy implementation at the local level. These differences expressed themselves in conceptions of both societal boundaries—the scale at which community was envisioned—and conceptions of the boundary between nature and culture. The findings confirm the need for the continued development of models of community‐based resource management as well as for the conceptual integration of society and nature in the realm of policy construction.  相似文献

Rain‐spells are a key parameter for examining the variation in rainfall amounts, especially in arid and semi‐arid areas. A rain‐spell is defined as a period of consecutive days with rainfall above a certain determined Daily Rainfall Threshold (DRT). Two different seasons or two stations may have the same average TOTAL, but different synoptic conditions are the cause for the differences in their Number of RainSpells (NRS) their Rain‐Spells Yield (RSY) or both. The present study examines whether a season is drier/wetter according to its length, or whether it depends on the NRS in 41 Mediterranean stations. It analyses the relationships between dry/wet seasons and various elements of the rain‐spells. These objectives are analysed both at a basin level of the entire Mediterranean, and at a station level. The main conclusions at the basin level are that precipitation amounts are not related to the length of the seasons, and therefore, a Short or a Long season can be either Dry or Wet. The significant positive correlation between the TOTAL and the annual NRS that was found indicates that a Dry season tends to have Few rain‐spells and a Wet season tends to have Many rain‐spells. At the station level of most stations, a Dry or Wet season is caused mainly by changes in the RSY and less so by changes in the NRS. This tendency is more evident in the southern Mediterranean. Furthermore, Wet seasons are characterized by an increase in the number of Long rain‐spells (longer than three days) and mainly in the RSY of these spells. These conclusions may serve to characterize the rainfall regime under any scenario due to a climatic change.  相似文献
