1944年《美国对外石油政策》报告探析

1944年4月11日美国国务院公布了《美国对外石油政策》报告。该报告将石油利益确定为美国国家安全利益的核心,其主要内容是:在中东地区推行"门户开放"政策,将大西洋宪章的"机会均等"原则运用于战后美国对外石油资源的争夺中;提出了美国对外石油供应的"半球"石油政策,即"东半球"的石油主要由中东地区供应,"西半球"的石油由美洲地区供应。美国对外石油政策的目标是攫取和控制中东地区的石油资源,保护美国国内的石油资源储备。考察《美国对外石油政策》报告的主要内容及其形成的过程,揭示美国战后对外石油政策的本质,有益于全面认识美国构建战后石油安全战略的全貌。     

Auf der Suche nach der Politik in der Wissensproduktion: Plädoyer für eine historisch‐politische Epistemologie

In Search of Politics in Knowledge Production. A Plea for a Historical‐Political Epistemology. Knowledge production has an intrinsic political dimension. Starting from this presupposition, it is argued that the systematic integration of and reflection on the political dimension is necessary for an adequate understanding of historical processes of knowledge production in the sciences. The consecutive plea for a historical‐political epistemology proceeds in two steps: First, it is illustrated that in a number of recent historical science study cases, the political dimension is frequently marginal, or even absent. After a short discussion of previous theoretical concepts to describe the impact of politics for the production of scientific knowledge, an approach is sketched which builds on Hans‐Jörg Rheinberger's historical epistemology and Bruno Latour's symmetrical anthropology. It is argued that in addition to Rheinberger's program to describe epistemic systems, the political dimension is intrinsic to three stages of the process of data production: First to an initial phase which consists in the arrangement socio‐technical configurations to produce new evidence. Here, factors such as the culturally shaped perception and evaluation of ?relevant”? problems, as well as the perception of career resources have to be taken into account. Second, the political dimension is relevant in view of the continuous re‐adjustments of the configuration of epistemic systems, e. g. towards newly available financial, technical, or intellectual resources and ?relevant”? challenges from outside the system. Thirdly, the data produced and represented by epistemic systems – “evidence” – are yet in need of interpretation. This process is in itself imbued with continuously shifting mechanisms of selecting and creating hierarchies amongst the pool of available data.     

Decline in firing technology or poorer fuel resources? High-temperature thermoluminescence (HTTL) archaeothermometry of Neolithic ceramics from Pool,Sanday, Orkney

The Neolithic ceramic assemblage from the multi-period coastal settlement at Pool on the island of Sanday, Orkney is unique because it stratigraphically spans both the earlier round-based (including possible Unstan bowls) and later flat-based (‘Grooved Ware’) traditions. High-temperature thermoluminescence (HTTL) analysis objectively demonstrates that ceramics from the earliest Neolithic layers have been consistently better fired compared to examples from later layers. We suggest two interpretations of these data: either firing technology declined with changing social structures and/or adoption of a different ceramic tradition or that there was greater pressure on fuel resource and management in the later Neolithic. Paleoenvironmental and chronological evidence indicate climatic deterioration in the later Neolithic, which adds further support to an interpretation of a poorer fuel resource at that time. In addition to studies of the HTTL signal, analysis of the ambient temperature modification of the TL signal has potential to support or evaluate dating evidence, and is readily applicable to optically stimulated luminescence (OSL) age data.     

Using a Web-based Resource to Prepare Students for Fieldwork: Evaluating the Dark Peak Virtual Tour

This paper reports on development of a Dark Peak website and its use to prepare first-year geography students for a one-day physical geography field course in the south Pennines. The Virtual Tour (VT) component of the website is the main focus of this paper. Pre- and post-fieldwork evaluations of the first version of the VT by 195 students are presented with the revisions undertaken as a result of this feedback. Recommendations for the design and implementation of virtual fieldwork websites are made. The current version is available at http://www.art.man.ac.uk/Geog/fieldwork/     

Pressures on Urban Water Resources in Russia: The Case of St. Petersburg

An American geographer evaluates the process of water resources planning and management in the city of St. Petersburg, Russia, based on regional government documents, interviews with local water management officials, and follow-up field observations in 2007. St. Petersburg is a microcosm for challenges to assessing and managing water resources in urban environments in transition economies more broadly, and thus the present study yields insights into obstacles confronting water planners in many large cities in the post-Soviet realm, and augments the body of empirical data on the impacts of economic transition on environmental management. 3 figures, 46 references.     

Some problems of regional planning in predominantly rural environments; the French experience in Corsica

Mortality data for ischaemic heart disease and lung‐bronchus cancer in the 29 metropolitan boroughs of London and the 37 electoral wards of Glasgow are standardised for age and sex relative to an all‐U.K. norm. The standardised mortality ratios (S.M.R.) obtained, when expressed in map form, reveal marked spatial inequalities. A relationship with social class and concomitant housing and living standards is indicated.     

长株潭城市群城镇化进程与水资源利用响应关系研究

采用层次分析法与熵权法相结合的方法,构建长株潭城市群城镇化综合发展水平和水资源开发利用综合潜力评价指标体系及响应关系模型,对2001-2015年间研究区域城镇化发展进程与水资源利用之间的动态过程进行定量研究,分析主要影响因素、变化特征以及两者响应特征。结果表明：长株潭城市群处于快速城镇化和规模扩张阶段,人口城镇化和空间城镇化水平高于经济城镇化和社会城镇化水平,城镇化发展质量有待提升;区域用水负荷逐年增加,虽然水资源利用效率和管理水平稳步提升,但水资源自然禀赋和开发利用程度受区域水文条件的影响显著。在2001、2005、2007、2009、2011年,长株潭区域城镇化的发展在一定程度上受到水资源系统的约束。协调好城镇化与水资源之间的关系,必须改变规模外延扩张模式,以控制水资源总量、有效提高水资源利用效率为目标,减弱水资源系统对城镇化发展的制约,提高水资源保障能力。     

明清时期福州西湖水环境变迁及其治理研究

明清时期,福州西湖水环境总体趋劣。明代西湖水源较为充足,水质状况良好;万历以降,受民间占垦等社会因素影响,湖域面积缩减,水质日渐趋下;清代中后期,福州城内水道淤浅,江潮渐绝,西湖水源趋向单一。明清时期西湖水环境的变动,除了受区域气候干湿变化、山地森林水土保持以及湖泊含沙量的影响之外,还与人为的水地之争密切相关。由于人地关系紧张,加之水资源权属不清、新垦湖田税赋征收模糊等,获取湖利的必然性刺激了民间占湖为地的行为。地方官府也曾采取如修闸筑坝护堤、追返侵地还湖、清理粪秽淤泥等治理措施,并取得阶段性成效,但受区域人口、土地资源与生存环境等社会经济因素的影响,西湖历经多次治理仍积弊难除。     

城市公租房社区生活空间质量研究——以西安市为例

以城市社会生活空间质量观理念为研究框架,运用核密度、缓冲区分析等方法从社区物质环境以及居民对社区感知两个维度对城市公租房社区的生活空间质量进行评价。研究发现：西安市公租房社区空间布局较为偏远,集聚特征明显;除教育资源外,医院、商业以及游憩等资源均处于低可获性状态;社区居民对公租房社区房屋面积、房屋质量、物业管理、社区绿化等方面满意度较低,社区归属感及长期居住意愿不强。西安市公租房社区在社区资源可获性方面存在一定的空间剥夺现象,社区整体生活空间质量水平不高。
