Health centre visits among the elderly with chronic ailments: Evidence from the Kanchanaburi Demographic Surveillance System, 2004, Thailand

This study deployed statistical and spatial (GIS) analyses to test the effects of geographic, demographic and occupational factors in predicting health centre visits among the elderly (≥60 years) with chronic ailments in Kanchanaburi Province, western Thailand. Datasets from the Kanchanaburi Demographic Surveillance System (2004 baseline survey and a 2006 project follow-up) comprised five land-use landscape and occupational strata: urban/semi-urban (industrial), rice field, plantation crop, upland and mixed economy. Travel distance to the nearest health centre was calculated following transportation routes and the GPS coordinates of individual home locations, and the number of healthcare visits under the national free universal coverage (UC) scheme reported for the previous year was used as a dependent variable in regressions. Broadly, the study found that distance was not a significant predictor of the rate of elderly health centres visits for those with co-residing spouses and/or adult children (77% of sample), and for the elderly still working (48% of the sample) who were the least likely to access healthcare. Owning motorised vehicles did not encourage visits, which also varied by land-use and occupational strata.     

Geographies of adult multigenerational family households in metropolitan Sydney

This paper investigates spatial trends of multigenerational adult families in metropolitan Sydney. Australia's immigrant gateway city, Sydney has high housing costs and infrastructure pressures, and planning policies support higher residential densities. In this context, the accommodation of persons living in multigenerational families is examined, by major region of origin, their geographies in Sydney, and by housing costs and constraints. Results highlight that cultural origins were influential in multigenerational household formations, and such formation is higher in areas of first and second ethnic community formation areas. Multigenerational living is also more common in middle ring and outer areas of cheaper housing. Implications are drawn for more nuanced housing policies in Sydney and comparable cities, given that detached and semi‐detached houses were favoured by these households, whereas two‐fifths of new housing constructed in Sydney in 2011 consists of two or less bedroom apartments.     

Phase‐field modeling of epitaxial growth of polycrystalline quartz veins in hydrothermal experiments

Mineral precipitation in an open fracture plays a crucial role in the evolution of fracture permeability in rocks, and the microstructural development and precipitation rates are closely linked to fluid composition, the kind of host rock as well as temperature and pressure. In this study, we develop a continuum thermodynamic model to understand polycrystalline growth of quartz aggregates from the rock surface. The adapted multiphase‐field model takes into consideration both the absolute growth rate as a function of the driving force of the reaction (free energy differences between solid and liquid phases), and the equilibrium crystal shape (Wulff shape). In addition, we realize the anisotropic shape of the quartz crystal by introducing relative growth rates of the facets. The missing parameters of the model, including surface energy and relative growth rates, are determined by detailed analysis of the crystal shapes and crystallographic orientation of polycrystalline quartz aggregates in veins synthesized in previous hydrothermal experiments. The growth simulations were carried out for a single crystal and for grain aggregates from a rock surface. The single crystal simulation reveals the importance of crystal facetting on the growth rate; for example, growth velocity in the c‐axis direction drops by a factor of ~9 when the faceting is complete. The textures produced by the polycrystal simulations are similar to those observed in the hydrothermal experiments, including the number of surviving grains and crystallographic preferred orientations as a function of the distance from the rock wall. Our model and the methods to define its parameters provide a basis for further investigation of fracture sealing under varying conditions.     

Young people's cartographies of school choice: the urban imaginary and moral panic

A critical geography of school choice illuminates how parental school choice reproduces unequal urban conditions. This paper contributes to this scholarship by arguing that the reproduction of urban spaces is reinforced by the ways the dominant urban imaginary shapes how youths imagine and organise their school options. I draw from the fields of critical geography, school choice, and sociology of moral panic to theorise how children's geographies are informed by the dominant urban imaginary and reconstituted reiteratively by moral anxiety. Through this lens, I analyse ethnographic data collected on school choice policy, along with interviews with 59 youth (ages 11–19) in Vancouver, Canada. My analysis demonstrates that the dominant forms of classed stigmatisation of marginalised urban schools are important to young people's rejection of those schools. My analysis also shows that moral panic and rising fears of violence underwrite the spatial patterns of youth participation in school choice.     

The Role of the Development Industry in Shaping Urban Social Space: a Conceptual Model

Socio‐spatial differentiation or the spatial arrangement of social groups in cities has long been the subject of scholarly attention in urban studies from a variety of perspectives. In many contemporary societies, the development industry plays an important and growing role in socio‐spatial differentiation. This paper presents a conceptual model for the empirical analysis of the role of this industry in shaping urban social space.     

论自然环境对人类社会发展作用方式

自然环境对人类社会发展的控制是一种可能性控制,这种控制的具体方式有四:一是经由自然稀缺性控制人类社会的持续发展;二是经由空间差异性控制人类社会的空间分化和区域发展;三是经由其时间上的变化控制人类社会发展的波动与周期;四是经由其使用价值的多样性控制资源与环境利用的社会选择范围与方向。作者对前两种方式做了重点论述。     

欧美旅游者在秦始皇帝陵博物院的情感体验时空变化

以时空思维为指导,从情感社会学、认知心理学、时间地理学等多学科角度,深入地展开了对旅游者情感体验的研究。采用访谈、问卷等方法,系统探索了欧美旅游者情感体验的影响因素。基于秦始皇帝陵博物院实际情况与欧美旅游者的表达习惯,参考双因素情感模型,确定基本情感词汇,建立情感轮分析模型进行数据收集,计算旅游者情感体验值。从时间、空间及路径3个角度,探索秦始皇帝陵博物院欧美旅游者情感体验的时间、空间变化规律和路径变化规律。研究发现秦始皇帝陵博物院欧美旅游者的积极情感体验整体呈倒“U”型波动,消极情感体验整体呈“U”型波动;欧美旅游者情感体验的空间分布表现出聚集节点与景区主要展馆高度契合的特点;旅游者的游览路径和游览顺序会影响其情感体验。

本文从三个方面论述了东亚经济发展模式。首先,从历史的角度分析了东亚经济发展模式的产生、特点及其局限性。然后,进一步指出在经济全球化和信息化加速发展新的历史条件下,东亚发展模式已不能适应时代发展的要求,东亚发展模式与这次东亚经济危机存在着内在的必然的联系。最后,对东亚经济发展模式的发展与变革提出了自己的观点。     

治理模式分异对旅游地发展的影响机制研究——阳朔遇龙河景区个案分析

如何实现有效治理是旅游目的地可持续发展中的重要议题。以阳朔遇龙河景区为个案,归纳其治理模式空间分异的类型与特征,解读不同模式对旅游发展的影响效应,发现：①村企共治模式中,各治理主体形成互助依赖的伙伴关系,资本互补、信任互惠、层级协同、信息对称、相互监督,能够兼顾效益、秩序与公平,游客满意度最高,呈现良性可持续发展态势;②社区主导模式中,治理主体权力失衡、信息不对称、短期工具理性、监管机制难以发挥持续实效,导致旅游秩序最差,游客满意度最低,不利于长远可持续发展;③政府主导模式中,政府公司治理能力不足,缺乏有效激励机制,导致商业效益较差,未能实现资源最优配置。
