生计与风水:清代湘南地区的矿业开发与生态环境

湘南地区毗邻赣、粤、桂三省,地理位置特殊,是一个复杂的地理单元。及至清代,湘南地区已是湖南省乃至全国铜、铅、银等矿业生产的主要区域。长达数百年的矿产开采与冶炼,促进了地方社会的经济发展,也给当地的生态环境带来深远影响。由此,湘南官绅民各界对矿业开发引发的环境问题亦有因应,“坑冶十害论”和“九嶷山封禁案”即为其集中体现。开矿采砂本为解决贫民生计而采取的措施,但因破坏风水、污染水土等一系列影响环境的后果,以致出现开矿与禁矿之争,使得湘南地区矿业开发一度出现波折。这两例个案亦折射出在“重本抑末”的传统社会中地方官绅士民在生计与风水之间的离合关系。地方社会以保护风水为由严禁矿冶,在一定程度上遏止了生态环境的破坏与恶化,不过,其在环保方面发挥的作用也不宜被高估。

从产业布局的角度探讨了国内近年比较热门的空港经济现象。首先从与机场最直接相关的人、物、资金和信息四大要素入手,剖析了空港经济主要产业类型及其特征,并分析了空港经济总体区位及其演变过程。在此基础上总结分析空港经济产业具有与发展阶段相吻合的增长极、点轴和网络三种布局模式,指出国内备受推崇的圈层布局是发展阶段不明确的理想模式,并尝试采用地理信息系统空间分析方法对产业布局的区位进行叠加分析。最后以广州新白云机场为例,探讨了周围花都区和白云区空港经济产业布局规划方案和措施。     

北京城市建成环境对居民宜居满意度的影响

基于2013年宜居北京大规模问卷调查数据和北京市基础地理信息数据,探讨了北京市居民宜居满意度的空间特征,并运用多层线性模型进一步分析城市建成环境对居民宜居满意度的影响。研究发现,北京市宜居满意度总体良好,空间分布存在中心高边缘低的特征。城市建成环境对居民宜居满意度存在显著影响。其中,丰富多样的服务设施、适宜的人口密度以及便捷的公共交通能够促进居民宜居满意度提升,而单一的土地利用和邻近商业中心则会降低居民宜居满意度。除此之外,城市建成环境对宜居满意度的影响在空间上存在异质性,同时建成环境对宜居满意度的影响在不同阶层中存在差异性,人口密度和服务设施多样性对中低收入群体的宜居满意度提升明显。

Children as urbanites: mapping the affordances and behavior settings of urban environments for Finnish and Japanese children

Increasingly, children are residing in urban environments, yet little is known about the urban affordances for children. A place-based approach was employed to map the urban experiences of over 1300 children residing in Helsinki (Finland) and in Tokyo (Japan) in terms of meaningful places (affordances), travel mode and accompaniment to these places. Shared affordances were considered behavior settings, and audited on-site by trained experts for their main function, land use, openness, and communality. Significant differences were found between countries for all affordance categories. Although differences in behavior settings were observed between countries, a number of patterns emerged: outdoor settings and those with shared communality were the most prevalent behavior settings, traffic settings were predominantly evaluated negatively and commercial and indoor settings most positively. Findings suggest that although the context is important, independent mobility and the possibility to actualize environmental affordances seem to be fundamental in both contexts as the key criteria for environmental child-friendliness.     

Radiocarbon age determinations of fossil Margaritifera auricularia (Spengler) from the River Thames in West London

In the early 1900s shells of a large freshwater mussel, Margaritifera auricularia (Spengler), were discovered in calcreted gravel dredged from the channel of the Thames at several sites between Mortlake and Battersea in west London. These specimens were said to have been associated with Neolithic polished stone axes, supposedly as food remains. M. auricularia is now extinct in Britain, but it has been reported living in several large rivers in southern Europe although apparently not in recent years. Three radiocarbon dates of 4140±50, 4340±45 and 4860±40 bp have been obtained from Thames specimens, supporting a Neolithic age for these shells. The theory that the shells represent debris from imported human food is discounted and it is considered more likely that M. auricularia was actually living in the Thames in Neolithic times. Its extinction in Britain should be seen as part of a general recession during the Post-glacial, as revealed by fossil occurrences to the north and east of its present-day range.

Geographic information system‐based evaluation of spatial accessibility to maternal health facilities in Siaya County,Kenya

Maternal mortality is a major problem in middle‐income and low‐income countries, and the availability and accessibility of healthcare facilities offering safe delivery is important in averting maternal deaths. Siaya County, in Kenya, has one of the highest maternal mortality rates in the country—far more than the national average. This study aimed to evaluate geographic access to health facilities offering delivery services in Siaya County. A mixed‐methods approach incorporating geographic information system analysis and individual data from semi‐structured interviews was used to derive travel time maps to facilities using different travel scenarios: AccessMod5 and ArcGIS were used for these tasks. The derived maps were then linked to georeferenced household survey data in a multilevel logistic regression model in R to predict the probability of expectant women delivering in a health facility. Based on the derived travel times, 26 per cent (13,140) and 67 per cent (32,074) of the estimated 46,332 pregnant women could reach any facility within one and two hours, respectively, while walking with the percentage falling to seven per cent (3,415) and 20 per cent (8,845) when considering referral facilities. Motorised transport significantly increased coverage. The findings revealed that the predicted probability of a pregnant woman delivering in a health facility ranged between 0.14 and 0.86. Significant differences existed in access levels with transportation‐based interventions significantly increasing coverage. The derived maps can help health policy planners identify underserved areas and monitor future reductions in inequalities. This work has theoretical implications for conceptualising healthcare accessibility besides advancing the literature on mixed methodologies.     

Urban homesteading and intensive mothering: (re) gendering care and environmental responsibility in Boston and Chicago

In this article, we explore how normative ideologies of good mothering are being reproduced and contested through urban homesteading, a sustainable lifestyle that emphasizes household self-provisioning. Urban homesteading practices may include gardening and urban agriculture, canning, and pickling, and a variety of do-it-yourself and craft projects. Based on qualitative research with 19 urban homesteading households with children in the Boston and Chicago Metropolitan areas, we argue that urban homesteading discourses and practices reflect and align with intensive mothering ideologies in the United States. Intensive mothering ideologies encourage a selfless devotion of physical, emotional, and mental energy to childrearing, and are often associated with individualized, privileged, and gendered subjectivities. We find these intensive mothering ideologies especially visible in the ways that mothers perceive and respond to environmental risk by adopting and enacting urban homesteading labors. We also note that the choice to respond to risk by homesteading is often, but not always, mediated and animated by economic, temporal, and social privilege. In this way, urban homesteading and surrounding discourses may inadvertently raise the bar of ‘good’ motherhood in ways that demand more of women and marginalize or burden mothers with less resources and privilege. However, rather than dismiss homesteading entirely on these grounds, we suggest that it may be possible to harvest impulses of care, connection, and collectivity associated with homesteading in ways that benefit rather than burden all mothers.
