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.     

THE IMPACT OF CRIME ON APARTMENT PRICES: EVIDENCE FROM STOCKHOLM,SWEDEN

This study uses data of about 9,000 apartment sales in Stockholm, Sweden, to assess the impact of crime on property prices. The study employs hedonic pricing modelling to estimate the impact of crime controlling for other factors (property and neighbourhood characteristics). Geographic Information System (GIS) is used to combine apartment sales by coordinates with offences, land use characteristics and demographic data of the population. The novelty of this research is threefold. First, it explores a set of land use attributes created by spatial techniques in GIS in combination with detailed geographical data in hedonic pricing modelling. Second, the effect of crime in neighbouring zones at one place can be measured by incorporating spatial lagged variables of offence rates into the model. Third, the study provides evidence of the impact of crime on housing prices in a capital city of a traditional welfare state, information otherwise lacking in the international literature. Our results indicate that apartment prices in a specific area are strongly affected by crime in its neighbouring zones, regardless of crime type. When offences were broken down by types, residential burglary, theft, vandalism, assault and robbery individually had a significant negative effect on property values. However, for residential burglary such an effect is not homogenous across space, and apartment prices in central areas are often less discounted by being exposed to crime than those in the city's outskirts.     

加拿大二线城市华人新移民经济融合研究——“三重玻璃效应”与移民向下层社会流动

论文对加拿大二线城市卡尔加里和爱德蒙顿华人新移民的主要特点、移民动机和融合过程中的主要障碍进行了分析,探讨了新移民在加拿大向下层社会流动的问题。研究显示,新移民在经济融合过程中遭遇多方面的障碍,尤其在就业和语言方面。他们在移民加拿大之后,经历了去技能化和以前的学历和工作经验贬值,促使他们向下层社会流动,而这种状况反过来又阻碍了他们的融合进程。华人新移民的负面经历可以归因于由玻璃大门、玻璃房门和玻璃天花板构成的"三重玻璃效应"。加拿大政府应采纳融合框架政策,除承认移民的流动自由外,还要保证他们能享有与其他加拿大人一样同等的公民权益。     

Elemental mobilities: atmospheres,matter and cycling amid the weather-world

Abstract

Everyday experiences of movement have become a central concern for social and cultural geography in recent years. Work here has begun to unpack the specific meanings, imaginaries and experiences that come to be bound up with mobile bodies and their practices. However, it has been suggested that more could be done to examine the material, elementary, molecular and physical aspects of movement which are significant to the experience of being on the move. Therefore, this paper explores the experience of cycling amid such turbulent ‘elemental’ materialities. Such ‘matters’ matter to cycling in the way that they (re)make both mobile environments and mobile subjectivities. Cyclists come to have quite immediate and intimate relationships with the material and ‘elementary’ aspects of the environments they move through given their relatively unmediated encounters with them. This paper draws on video-interview based research with 24 commuter cyclists in Plymouth, UK to consider cyclists’ experience of atmospheric conditions in terms of air’s force and air quality. From this, the paper reflects on how the experience of such ‘elemental’ matters might be significant to future research on and planning for cycling.     

基于腾讯迁徙数据的中国“春运”城市间人口流动空间格局

“腾讯迁徙”大数据基于位置服务，实时、动态、完整、系统地描述了用户日常出行活动的轨迹。通过采集“腾讯迁徙”数据平台中2018年春运期间中国346个地级及以上城市之间的逐日人口流动数据，分“节前、节中、节后”3个时间段，利用复杂网络分析方法，从人口流动的集散层级、集散体系分层集聚特征、人口流动空间格局、网络空间特征等角度分析各时间段城市间的人口流动特征与空间格局。结果表明，腾讯迁徙大数据直观地揭示了春运期间中国城市间人口流动空间格局，3个时段人口的净流入均呈现十字形骨架支撑的菱形分布，人流集散中心主要集中在京津冀、长三角、珠三角和成渝4大城市群，与城市等级有较强的一致性。人口流动集散体系呈明显的分层集聚，城市行政级别的高低与人口流动影响力存在一定的正相关关系，大部分城市人口流动处于“相对平衡”状态。人口流动网络呈现东密西疏的分布特征和东部并联、西部串联的网络关联特征。人口流动网络局部具有较明显的“社区”结构特征，聚为3个大区级、5个跨区域级和1个地区级社区。     

Rethinking music geography through the mainstream: a geographical analysis of Frank Sinatra,music and travel

This paper brings a new perspective to music geography by focusing on how a particular mainstream musician helped to construct, subvert, and circulate meanings associated with travel. It asserts that Frank Sinatra, via his music and actions, engaged with travel in ways that frequently ran counter to how it has commonly been enacted in American music and popular culture. Particular attention is paid to the singer’s travel-themed album, Come Fly With Me. By the time of its release in 1958, Sinatra, via a public persona that encompassed performer, ‘playboy’ and businessman, was a central figure in promoting an alignment of leisured mobility with postwar economic success. The paper interrogates how Sinatra’s celebrity allowed him to embody travel in certain real and imagined ways. It also examines what the resulting representations revealed about performances of gender, ethnicity, and status, and the expected modes of behavior that were associated with them, in America’s postwar consumer-driven society.     

Inside Checkpoint 300: Checkpoint Regimes as Spatial Political Technologies in the Occupied Palestinian Territories

As a part of the architecture of the Israeli occupation of the Palestinian Territories, the Israeli government introduced in 2005 a series of so‐called terminal checkpoints as “neutral border crossings”, to minimise the impact of these barriers on Palestinian lives through a different design and the use of several machines, such as turnstiles and metal detectors. In this article, we analyse terminal Checkpoint 300 in Bethlehem, framing it as a spatial political technology aimed at controlling the movement of Palestinians. More specifically, we investigate the interactions between Palestinian commuters, Israeli soldiers/security guards and the machines operating inside Checkpoint 300. We conclude by suggesting that Checkpoint 300 is a porous barrier whose regime is produced, reproduced but also challenged by such interactions, and that, despite the new “neutral design”, Checkpoint 300 is a place still filled with tension and violence, often exercised by the machines and their “decisions”.     

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.
