CREATING A SENSE OF PLACE: THE VIETNAMESE-AMERICANS AND LITTLE SAIGON

Based on a study of Little Saigon, an ethnic enclave in Westminster, California, this paper examines the physical, social, symbolic and emotional significance of such places in the lives of immigrants. We focus on three specific aspects of the ethnic enclave: architectural elements, everyday social interaction within the enclave, and public ritual events. We highlight how the built architectural environment and the immigrants' social, commercial, and ritual activities interact to create and sustain a sense of place, foster community identity, and structure social relations. We conclude that ethnic enclaves constitute an important aspect of an immigrant's place identity enabling him/her to simultaneously remain connected to the places left behind and yet appropriating and forging significant new place ties.     

Linkages in Ghana's gold mining industry: Challenging the enclave thesis

By 2009, Ghana was the second-ranked African producer after South Africa, and had become the world's ninth largest producer of gold, at some 3.8% of global production, up from 2.6% five years earlier. Gold production volumes and revenues rose significantly over the decade from 2000. Yet gold mining tends to be perceived negatively in Ghana, and is seen as providing far less than it should in terms of public revenue, employment, skills development and spillovers, and localised economic development. Gold mining is often depicted as having an enclave status, disconnected and isolated from the rest of the economy. In contrast, the research findings here demonstrate that after a period of strong investment and growth, gold mining can no longer be viewed as an enclave activity: it is in fact more deeply linked into the Ghanaian economy than hitherto understood, through a set of as yet under-researched but promising economic linkages, notably backward linkages, which can potentially be strengthened by policy and support measures.     

Forecasting environmental equity: air quality responses to road user charging in Leeds, UK

Sustainable development requires that the goals of economic development, environmental protection and social justice are considered collectively when formulating development strategies. In the context of planning sustainable transport systems, trade-offs between the economy and the environment, and between the economy and social justice have received considerable attention. In contrast, much less attention has been paid to environmental equity, the trade-off between environmental and social justice goals, a significant omission given the growing attention to environmental justice by policy makers in the EU and elsewhere. In many countries, considerable effort has been made to develop clean transport systems by using, for example, technical, economic and planning instruments. However, little effort has been made to understand the distributive and environmental justice implications of these measures. This paper investigates the relationship between urban air quality (as NO2) and social deprivation for the city of Leeds, UK. Through application of a series of linked dynamic models of traffic simulation and assignment, vehicle emission, and pollutant dispersion, the environmental equity implications of a series of urban transport strategies, including road user cordon and distance-based charging, road network development, and emission control are assessed. Results indicate a significant degree of environmental inequity exists in Leeds. Analysis of the transport strategies indicates that this inequity will be reduced through natural fleet renewal, and, perhaps contrary to expectations, road user charging is also capable of promoting environmental equity. The environmental equity response is, however, sensitive to road pricing scheme design.     

我国实施循环经济的制度初探

循环经济是在资源与环境约束下追求有效经济增长的一种新的经济发展模式。循环经济本质上是一种生态经济,以资源利用的生态性、技术基础的复杂性、经济运行的社会性等为根本特征。制度与循环经济相互依存、相互制约,发展循环经济离不开制度的规范和引导。论述了我国当前在市场经济条件下发展循环经济中遇到的制度障碍,如市场机制障碍、产权制度障碍和政策法规障碍等,并提出解决循环经济发展的制度障碍需要建立一个完整的、相互补充的制度体系。

Sustainable urban community development from the grassroots: Challenges and opportunities in a pedestrian street initiative

Abstract

A local sustainable development initiative to establish a temporary pedestrian zone within a Canadian urban community served as a research study into the efficacy of social capital in the development of a network for community action. This community-based initiative used social capital to overcome campaign obstacles and the campaign itself generated new social capital within the neighbourhood through the creation of adaptive networks of participants. The campaign succeeded in creating a part-time pedestrian-only space that serves as an educational example of change for sustainable community development that is replicable in other communities, and provides an example of alternative occupation of community space. Contrary to other literature, little evidence of “core burnout” was found although the network does continue to expend a large amount of effort and time on fundraising. While social capital is a powerful tool for local grassroots action, the availability of a critical source of economic capital may prove vital to the long-term success and sustainability of the network.

上海市港城经济联动发展研究——基于建设现代化港口城市的背景

上海市要建成现代化港口城市,必须具备发达的港口经济与和谐的港城关系。从实现上海市港城经济联动发展的目的出发,将港城经济系统划分为城市经济子系统和港口经济子系统,选取具有代表性的指标,对2001—2010年间的数据进行灰色关联度分析。结果表明,保险业、信息业对港口经济的联动性较强,城市基础设施、集疏运体系和金融业对港口经济的支撑不足,且港口经济的外贸依存度不高,因此上海市需加快基础设施、金融业和现代物流业的配套建设。

Immigrant integration models in “illegal” communities: Postville Iowa's shadow context

Immigrant integration models in rural communities are limited because they do not acknowledge the context of illegality that exists within communities that have a high concentration of unauthorised immigrants. In this in-depth case study of Postville, Iowa (the site of an infamous US immigration raid), I examine current rural immigrant community integration strategies under a shadow context of illegality and unauthorised immigrant labour. I find that underground and informal relationships within the towns' employers, immigrants, civic leaders, and native townspeople sustain a shadow context of exploitation and community instability. My research demonstrates that communities with large unauthorised immigrant populations rely on both formal and informal immigrant integration strategies to create “welcoming” immigrant communities. The formal strategies are multicultural approaches that rely on “diversity champions” to instil a climate of inclusion but do not tackle structural issues that place unauthorised communities at risk. The informal strategies rely on tacit understandings of community behaviour that just perpetuate the structural conditions of exploitation present in rural towns. These two forms of immigrant integration strategies support a shadow context that breeds vulnerability and risk for unauthorised immigrants, even in an immigrant “welcoming” environment.     

Can home gardens scale up into movements for social change? The role of home gardens in providing food security and community change in San Jose,California

Urban policymakers and sustainable food activists have identified urban agriculture as an important strategy for confronting a host of urban problems, including food insecurity, health disparities, access to urban green space and community economic revitalisation. Much recent work on urban agriculture has examined community and school gardens, but little research has been undertaken on home gardens as a solution to urban problems. This article examines a home-gardening programme in San Jose, California, La Mesa Verde, asking whether some of the benefits found in community gardens can be found in home gardens. Specifically, we look at financial, health and community benefits, examining the potential of home gardens to become forces for broader social change. We ask whether gardens can become agents of cultural preservation, self-determination, particularly for recent immigrants who use these spaces to build identities and work towards collective action and self-determination.
