R esidential m obility is one of the most important forces underlying changes in the social composition and physical characteristics of urban areas (Rossi 1955, p. 2). Consequently, numerous studies on residential migration have been carried out in order to comprehend this process better and thereby aid in the assessment of migration theories and in the development of appropriate models. Mobility studies have examined the characteristics of outmigration areas and households, motivations to move, satisfaction achieved through relocation, and the impact of residential changes. However, as Maher (1974) points out, previous analyses are incomplete in that they tend to focus on the demand characteristics of residential relocation and to omit the supply side of the process, the available housing stock. This study attempts to rectify this omission by considering the provision of newly constructed single-family detached housing in Windsor and the resultant migration patterns and processes through vacancy chain analysis. The demand and supply concepts of residential mobility are examined with regard to the housing multiplier generated by different locations and values of new homes, the socio-economic and demographic characteristics of households at various positions in the turnover process, the reasons for moving, and the spatial patterns of residential moves originating from new housing. In addition, by focusing on a specific form of housing the study avoids problems which may arise from aggregate level analyses of households adjusting to new housing opportunities.  相似文献

"The paper examines the validity of current theories of intra-city migration, subjecting those theories to the test of explaining new data collected in a total of 13 low-income settlements in three Latin American cities: Bogota, Mexico City, and Valencia, Venezuela. The study focuses attention upon the principal reception points for migrants; the location of previous place of residence for contemporary barrio dwellers; [and] the tenure and dwelling characteristics of previous places of residence. The authors conclude that residential patterns in Latin American cities are less the outcome of migrant choice, as some theories argue, and more the product of constraints imposed upon the land and housing markets."  相似文献

The effects of COVID-19 have been profoundly felt across higher education as across broader society. In particular, the pandemic has revealed that many of our most stubbornly entrenched inequalities do not simply follow gendered fault lines, but rather care fault lines. In this article, we adopt a maternal epistemology and collaborative witnessing to outline the disruption that academic mothers have experienced during the pandemic. However, we argue that this disruption is not simply obstructive to academic mothers and other caregivers. Rather, COVID-19 has provided a potentially transformative moment for the visibility and normalisation of care in the academy. It has forced the complex negotiation of paid work and care work that academic mothers must constantly manage into the spotlight. The pandemic has provoked an opportunity for a different performance of mothering in the academy; one that does not require us to invisibilise our care to be valued. This (re)performance and revaluation has the potential to reform the cultural landscapes of the academy, towards spaces in which care is reimagined as not simply an encumberment but also an enrichment.  相似文献

While much attention has been paid to the ways in which the private sector is now embedded within the field of development, one group of actors — for-profit development consultancies and contractors, or service providers — has received relatively little attention. This article analyses the growing role of for-profit consultancies and contractors in British aid delivery, which has been driven by two key trends: first, the outsourcing of managerial, audit and knowledge-management functions as part of efforts to bring private sector approaches and skills into public spending on aid; and second, the reconfiguration of aid spending towards markets and the private sector, and away from locally embedded, state-focused aid programming. The authors argue that both trends were launched under New Labour in the early 2000s, and super-charged under successive Conservative governments. The resulting entanglement means that the policies and practices of the UK government's aid agencies, and the interests and forms of for-profit service providers, are increasingly mutually constitutive. Amongst other implications, this shift acts to displace traditional forms of contestation and accountability of aid delivery.  相似文献

Norman Duncan (1871–1916) is best known as the Canadian expatriate author of adventure stories set in the fishing ports of Newfoundland at the turn of the last century. But Duncan, who was at the time a journalist in New York, began his career as a fiction writer in quite different territory. His first book was the mostly forgotten short story cycle The Soul of the Street: Correlated Stories of the New York Syrian Quarter (1900). In providing analysis of that book's cyclical structure and sociopolitical themes, the present essay shows that The Soul of the Street deserves to be better known for comprehensive literary-historical, political-cultural, and aesthetic reasons that should continue, some hundred years after its publication, to have an engaging, and indeed an increasing, relevance for our multicultural urban world.  相似文献

ABSTRACT. In this paper, a conditional location problem on a weighted network is examined. Attraction functions are defined and the problem is formulated as a mixed integer program. A method which simultaneously locates an additional facility on the given network and optimizes its weight is then described. A numerical example is provided.  相似文献
