云南省入境旅游空间集聚性演变及灰色模型预测分析

利用标准差、市场占有率、地理集中指数、变异系数和赫芬达尔指数对云南省入境客流量的空间集聚状况进行定量分析.研究表明：云南省各市州入境旅游接待规模差异较大,入境客流量的空间集聚性较强,入境旅游市场分化程度较低,市场竞争激烈,入境客源分布较为平衡.以云南省统计年鉴2001～2012年的入境旅游数据为基础,建构GM（1,1）模型并进行精度检验.研究表明：模型预测结果与实际数据几乎一致,进而利用该模型对云南省未来入境旅游指标进行预测.     

Gypsy Architecture: Houses of the Roma in Eastern Europe

Why is Ortley Beach, New Jersey, known as Superstorm Sandy's ground zero? This article employs qualitative vulnerability analysis to understand why vulnerability of second homes in Ortley Beach resulted in dune failure and slow rebuilding after Sandy. The second-home owners who largely make up the community in Ortley Beach are identified as the key vulnerable group. This group's lack of political representation and financial compensation after Sandy increased house damage and slowed rebuilding. Identifying the level of vulnerability of the majority group in a location is paramount to understanding how the community recovers from a disaster. Such identification can also aid in preparing communities, especially for types of disasters they have not yet encountered.     

Darkness on the Edge of Town: Mapping Urban and Peri-Urban Australia Using Nighttime Satellite Imagery

This article explores the use of nighttime satellite imagery for mapping urban and peri-urban areas of Australia. A population-weighted measure of urban sprawl is used to characterize relative levels of sprawl for Australia's urban areas. In addition, the expansive areas of low light surrounding most major metropolitan areas are used to map the urban–bush interface of exurban land use. Our findings suggest that 82 percent of the Australian population lives in urban areas, 15 percent live in peri-urban or exurban areas, and 3 percent live in rural areas. This represents a significantly more concentrated human settlement pattern than presently exists in the United States.     

The Recent Evolution of Canadian Inventive Enterprises

While inventive activity is necessary for industrial economies to progress, little is known about the types of enterprises inventing in Canada. The present study examines a typology of Canadian inventive enterprises at the national, subnational, and urban levels and the types of inventions developed in these areas from 1975 to 1989. Canadian patent and industrial directory information shows that Canada's largest enterprises are the most inventive, followed by small and then medium-sized enterprises. Although Canadian enterprises used teams of inventors to develop a considerably larger share of their inventions by 1989, they became discernably more inventive in only one industry after 1981 while concentrating on many process inventions between 1975 and 1989. Geographically, Canada's two largest cities and its core region were adversely affected by the declining inventiveness of this nation's large and foreign-owned enterprises during the 1980s. With respect to Canada's periphery, many of the characteristics typical of Canadian inventive enterprises were not readily apparent in this region, which had a more specialized inventive base than did the core.     

The Geography of Mutual Fund Assets

Mutual funds are the primary investment vehicle for individual retirement savings, but the spatial aspects of mutual fund investments have not been examined. This paper discusses the characteristics of the mutual fund industry and compares them to other financial industries. Previous studies of the financial industry and quaternary location theory are used to formulate three hypotheses predicting the distribution of mutual fund assets: (1) mutual fund assets will concentrate in the largest urban centers; (2) mutual fund assets will become increasingly concentrated in financial centers over the 1986-1996 period; and (3) the distribution of mutual fund assets will be similar to the distribution of other financial activities. Examination of mutual fund asset data from 1986 and 1996 did not fully support any of the three hypotheses. These findings suggest that the standard elements of quaternary location theory may need to be reevaluated.     

A New Indicator for Evaluating Spatial Concentration Based on Local Spatial Decompositions of the Gini Coefficient

Measuring spatial concentration is a key problem when studying geographical phenomena in many areas, including economic activities, atmospheric pollution, animal habitats, and so on. Two important aspects related to the measurement of spatial concentration are data variability and spatial autocorrelation. Rather than combining different indicators for each of these characteristics, this article proposes a new indicator based on the reconstruction of local spatial decompositions of the classical Gini coefficient. A Monte Carlo simulation study is conducted to evaluate the properties of the new indicator, and the results demonstrate that the indicator is highly linearly correlated with both spatial autocorrelation and data dispersion. Moreover, its elasticities to either the spatial autocorrelation or data dispersion are extremely close to 1 under various experimental circumstances. These findings indicate that the new indicator can reflect not only the absolute level of but also the change in spatial concentration effectively. Applying the indicator to the per capita gross domestic product data set for the middle reach of the Yangtze River, we also demonstrate that the new indicator and its local components are easy to implement and are useful in local spatial association analyses.     

Loose threads: The translocal making of public space policy in Hanoi

This paper analyses the recent developments in public space policy in the city of Hanoi, Vietnam. It has three aims. The first is to look at a potentially progressive urban policy in contrast to most work on ‘policies in motion’ that has primarily been concerned with neoliberal policies. The second is to put the process of public space policymaking in Hanoi in historical and cultural perspective. We therefore describe public space in Hanoi as historically constituted by different layers of meaning and physical urban patterns. The paper's third aim is to analyse the translocal connections involved in a policy that is still in the making, and therefore characterized by a series of ‘loose threads’. We show how different types of connections – policy mobility, topological relations and inter‐referencing – relate Hanoi to multiple locales elsewhere. The conclusion reflects on the ‘politics of reception’ showing how analysing a policy in the making develops a critical analysis of policies in motion.
