美国海峡群岛国家公园环境教育实践经验及对中国的启示

海洋海岛类国家公园是中国国家公园体系的重要类型之一,开展环境教育建设对于国家公园公益性的发挥具有重要作用。本文根据美国海峡群岛国家公园的实地考察及资料分析环境教育特点,总结环境教育实践经验,提出对中国海洋海岛国家公园环境教育体系建设的启示。结论如下：（1）海峡群岛国家公园环境教育具有生态系统及景观特殊性、教育场所弱可达性及教育方式多元性。（2）海峡群岛国家公园环境教育体系以教育内容和支撑体系为主体架构,其中教育内容划分为海岸、海岛、沿海（潮间带与泛洪区）、海下区域4类,支撑体系涵盖管理、资金、解说、传播、人才5个方面。（3）中国海洋海岛国家公园环境教育可在统筹管理、解说规划、人才培养等多方面予以借鉴,以探索符合中国国情的海洋海岛国家公园的环境教育建设模式。     

Charleston's newfound “entertainment zone”: should we be concerned?

This CIT Research Letter addresses issues related to the night-time economy and the rapid proliferation of bars along a section of a tourism oriented city's main street. Merely 10 years ago, locals did not frequent the area, it was of no interest to tourists, and it was regarded as a neighbourhood where one would not want to walk, especially at night. However, with the area's transformation to the nightlife centre of the city, issues have arisen that are of concern to city government officials. This paper considers these concerns.     

中国城市竞争力与基础设施关系的实证研究

城市竞争力是城市产业创造价值的综合能力，提高城市竞争力必须清楚影响城市竞争力的关键因素，本文提出城市竞争力与基础设施竞争力关系的假说后，选取中国部分城市的样本指标数据，利用主成份分析方法，构造城市竞争力和基础设施竞争力指数，运用模糊曲线分析方法，对理论假说进行了初步的检验分析，结果显示：基础设施是城市竞争力最重要的成或影响力量，技术性基础设计对城市竞争力越来越至关重要。     

城乡居民收入差距现状分析与缩小路径研究

面对城乡居民收入差距有所扩大的现状,文章利用《湖南统计年鉴》内的数据测算了2004-2013年十年内城乡居民收入的泰尔指数,分析了经济发展不平衡、人力资源差别、房地产畸形发展等扩大居民收入差距的原因。通过对城乡居民收入泰尔指数变化的研究,探讨了发展城乡经济、加大财政投入、推进户籍制度改革等缩小居民收入差距的路径。

Impact of commuting by workers on household dietary diversity in rural India

Drawing insights from the literature on transformation of rural non-farm employment, pathways from agriculture to nutrition, and linkages between migration and nutritional status of household, we seek to understand differences in dietary diversity across three mutually exclusive types of rural Indian households: where all members work in rural areas, at least one member commutes to urban areas, at least one member has no fixed place of work. Our analysis is based on a nationally representative data set from India for the year 2009–10 and we use propensity score matching methods. We find that as compared to households with no commuters, households with rural–urban commuters have higher dietary diversity; whereas households with no fixed place workers have lower dietary diversity. We also find differences in dietary diversity across households which differ by their primary source of income.

The ‘Urban Age’ in Question

Foreboding declarations about contemporary urban trends pervade early twenty‐first century academic, political and journalistic discourse. Among the most widely recited is the claim that we now live in an ‘urban age’ because, for the first time in human history, more than half the world's population today purportedly lives within cities. Across otherwise diverse discursive, ideological and locational contexts, the urban age thesis has become a form of doxic common sense around which questions regarding the contemporary global urban condition are framed. This article argues that, despite its long history and its increasingly widespread influence, the urban age thesis is a flawed basis on which to conceptualize world urbanization patterns: it is empirically untenable (a statistical artifact) and theoretically incoherent (a chaotic conception). This critique is framed against the background of postwar attempts to measure the world's urban population, the main methodological and theoretical conundrums of which remain fundamentally unresolved in early twenty‐first century urban age discourse. The article concludes by outlining a series of methodological perspectives for an alternative understanding of the contemporary global urban condition.     

Unveiling Urban Sprawl in the Mediterranean Region: Towards a Latent Urban Transformation?

The relationship between form and function in European Mediterranean cities has been widely addressed from various perspectives. A number of studies indicate that, until the 1980s, compactness was a key trait of several cities of the Northern Mediterranean. However, after the ‘compact growth’ period, these cities experienced patterns of urbanization that differed from their traditional trends. Since the 1990s, sprawl, coupled with population decline in the inner cities, has become the main pattern of urban development. This article explores the key features of exurban development in the Mediterranean region in order to provide material for a discussion based on the differences and similarities in the characteristics of sprawl processes originating in the US and Northern Europe. It concludes that any debate on policy responses to sprawl must be specifically formulated according to the scope, administrative level, housing and planning system, territorial and socioeconomic characteristics of the urban system under examination. It is our belief that sprawl requires site‐specific analyses and policy strategies for the region being studied if the process is to be effectively controlled.
