SPATIAL DEPENDENCY OF SEGREGATION INDICES

A few researchers have mentioned the scale sensitivity of segregation index, D. In this paper, I discuss analytically and empirically why using large enumeration areal units usually results in low segregation measures, and using small areal units produces relatively high segregation measures. The discussion is also applicable to the multi-group variant of D. A major finding is that if people of the same ethnic groups are positively spatially auto-correlated, increasing the size of areal units of analysis may not lower D initially, because only people of the same group are added. But enlarging the areal units subsequently may include population of other ethnic groups, and therefore could lower D. However, if the boundaries of the larger enumeration units are drawn to include only population of the same group, then D will not change significantly. Both the spatial autocorrelation of ethnic group population and zonal pattern are critical factors in determining the scale sensitivity of D.     

Spatial and social mobility

This paper analyzes the relationship between spatial mobility and social mobility. It develops a two‐skill‐type spatial equilibrium model of two regions with location preferences where each region consists of an urban area that is home to workplaces and residences and an exclusively residential suburban area. The paper demonstrates that relative regional social mobility is negatively correlated with segregation and inequality. In the model, segregation, income inequality, and social mobility are driven by differences between urban and residential areas in commuting cost differences between high‐skilled and low‐skilled workers, and also by the magnitude of taste heterogeneity.     

Spatial optimisation of fire service coverage: a case study of Brisbane,Australia

In the context of changing demand for fire services, spatial optimisation of fire coverage has attracted little scholarly attention despite its potential to improve emergency response and to inform future service planning for fire stations. Drawing on small area population forecasts, this paper extends the application of the Maximum Coverage Location Model to compute and delineate the spatial coverage of current and proposed new fire stations to align with population growth estimates for Brisbane, Australia. Our results reveal important gaps in fire cover that are likely to emerge as a result of predicted population growth, the spatial patterns of which varies across the Brisbane metropolitan area. We draw on these results to delineate a series of new potential sites for fire stations to ameliorate the reduction in spatial coverage as a consequence of predicted population growth demonstrating the utility of our analytic approach for decision‐making and operational planning in the fire services.     

Immigration and the making of place in Paris

Since the late nineteenth century, France has been a destination for people outside its borders. In recent decades, most immigrants have come from outside of Europe, often from ex-colonies in Northern Africa, West Africa, and Indochina. The Parisian area has welcomed a disproportionate share of these immigrants and neighborhoods have been shaped and reshaped to reflect their presence. This paper examines three neighborhoods in Paris—Belleville, the Triangle de Choisy, and the Goutte d'Or—which are each composed of and shaped by separate ethnic populations. To a great extent, these neighborhoods are imprinted by commercial activity, often involving customers who come from well outside the neighborhood and networks that extend beyond the nation. They also show patterns of multiethnicity which allows for difference between groups to be maintained, even as the space shared between them is effectively negotiated.     

1992年以来我国城镇居民居住消费的变化趋势

1992年之后,我国明确了建立社会主义市场经济体制的目标,城镇住房制度改革取得了实质性突破,城镇居民居住消费发生了深刻变化。居民购房公平自由,私有住房的比重急剧攀升,住房设施日益完善,居住环境不断优化,居住开支迅猛增长,城镇居民居住水平获得了前所未有的提高。然而受不正确的思想观念的影响,在居民居住消费过程中,一些诸如住宅私有率过高、住宅面积过大、一房伴终身等严重脱离实际需要和基本国情的问题日益突出。     

Human Response to Climate Change during the Umm an‐Nar/Wadi Suq Transition in the United Arab Emirates

Stable oxygen isotope ratios in archaeological human dental enamel represent an under‐utilised tool in the examination of changing climatic patterns in the ancient world. In the Oman Peninsula at the end of the third millennium bc , rapid aridification was accompanied by a breakdown in interregional trade relations; however, the human response to these changes is poorly understood. At the Bronze Age necropolis at Shimal in the United Arab Emirates, dental enamel from individuals interred in both Umm an‐Nar (ca 2700–2000 bc ) and Wadi Suq (ca 2000–1300 bc ) tombs underwent oxygen, strontium and carbon isotope analyses to examine how local inhabitants of southeastern Arabia responded to both environmental and socioeconomic change. While individuals from Shimal exhibit a clear shift in mean δ¹⁸O_c(VPDB) values from the Umm an‐Nar (−3.5 ± 0.6‰, 1σ) to the Wadi Suq (−2.4 ± 0.9‰, 1σ), corresponding ⁸⁷Sr/⁸⁶Sr and δ¹³C_ap signatures display homogeneity indicative of continuity in Bronze Age lifeways. Together, these data highlight the ability of local communities to successfully adapt to their changing environs (in lieu of societal collapse or a shift to a more mobile lifestyle) in an effort to maintain their way of life.

Second home conversion during the economic crisis: the case of Artemida,Greece

The conversion of second to primary homes is a known phenomenon; yet, its emergence as a result of necessity in an era of economic crisis has not been adequately addressed in the literature. To fill this gap, the article discusses an interview study of younger adults who have made this conversion, conducted in a second home area near Athens, Greece. The study explores the factors that influenced respondents to move permanently to their second home and perceptions of their relocation. Given the ongoing economic crisis in Greece, the research is placed in a unique socioeconomic context, allowing the investigation to delve into the effects of the economic crisis on these housing choices, by comparing perspectives on conversions having taken place before and during the crisis. Findings depict second home mobility as a complex phenomenon linked to tourism, changing housing needs, social factors, economic pressures, but also new potential urban functions arising from the current economic depression in Greece.     

Emerging Chinese Role in Shaping St. Petersburg's Urban Landscape: Interscalar Investment Strategies in the Development of a Residential Megaproject

The paper, by an American geographer, discusses the origin and development of a Chinese-financed residential megaproject (Baltic Pearl) located southwest of St. Petersburg's historical district. Viewing Baltic Pearl as reportedly the largest investment project undertaken outside China by a government-sponsored Chinese consortium, the author places it in the context of state-level Sino-Russian relations and Russian unease over the influx of Chinese migrants and culture. Reflecting the author's extensive field work in St. Petersburg and Shanghai, the focus of the paper is on the way the consortium was forced to adopt interscalar (i.e., both state and municipal/urban) strategies responsive to local conditions, providing a potentially useful precedent and model for Chinese and other investors seeking to penetrate Russia's urban markets.
