During 1993 advertised geography lectureships in British Universities reached unusually high levels, most probably due to major structural changes in tertiary education and the provision of funding attached to research ranking, superimposed on the general trends of increasing student numbers and an ageing academic population. As the research assessment exercise takes place every four years, and the new academic league tables have just been published, it is predicted that a similar surge in advertised lectureships will occur during 1997 and 1978. Research active New Zealand geographers are well placed to capitalise on this projected recruitment phase, which is likely to peak between April and July and again in November. Some specialist subjects within the discipline are in greater demand than others although their popularity may change over time. Many of the traditional obstacles that have in the past discouraged New Zealanders from targetting an academic position in Britain are now more perceived than real. 相似文献

"[This] paper devoted to the settlement system and the problem of rural population loss in that portion of West Siberia having a significant agricultural base takes issue with some implicit assumptions incorporated within the General Scheme of Settlement within the USSR. More specifically, policies calling for the deliberate, i.e., forced, resettlement of rural population in selected villages in order to provide economies of scale in rural services provision are criticized on two major counts: (1) that such 'enlarged' settlements will still be too small to be allocated the necessary range of functions according to standard city-planning formulae, and (2) that they accelerate rural depopulation by serving as spring-boards for migration to still larger centers." 相似文献

This paper takes a new approach to investigating people who age in place. It provides an explanation for why people age in a place that can be useful in government and corporate planning. Our research investigates the principal factors that drive the decision of a rising number of older Australians to age in place. Many older people wish to age in place rather than move in with their children or be institutionalised. They wish to continue to be active in their local communities and maintain their existing social ties. The concept of ageing in place covers two distinct groups: those who are able to stay in their current dwellings and age in home and those who move house but remain in their local community and age in neighbourhood. Age-friendly home modification is a response to ageing in home, whereas the provision of institutional healthcare and the provision of age-suitable housing to facilitate downsizing are associated with ageing in neighbourhood. Using Household, Income and Labour Dynamics in Australia (HILDA) survey data, this research examines the mobility decisions of older Australians and identifies the major determinants of a decision to age in place. This research argues for a better understanding of ageing in place, differentiating between those ageing in home and those ageing in neighbourhood. 相似文献

Service provision to remote rural areas is extremely costly, and only likely to be effective if the services provided are appropriate and accessible to the population. To date, little is known about the attitudes of rural residents (both townsfolk and the farming population) to various services. This study examines people's attitudes towards services generally, and health services in particular, and relates their attitudes to sociodemographic variables and geographical location. The results show the overwhelming importance attributed to health services, particularly medical services, and that attitudes differ significantly according to place of residence and by age group. These findings have major implications for those responsible for formulating policies relating to service provision for rural areas. 相似文献

教育公平是社会公平的重要基础,也是多学科交叉的研究热点。城市地理学者惯用空间可达性方法评价城市内部教育资源配置的均衡性与公平性,基于此,结合学区制度下义务教育资源供给方式的特殊性,提出教育资源社会-空间可达性理念,分别以地理可达性、机会可得性和经济可能性衡量教育服务的获取难度及其空间差异。以公办小学和初中学区为空间单元,通过比较2008年和2018年南京主城区教育资源社会-空间可达性发现:地理可达性内城优于外围的空间差异正在缩小,而机会可得性和经济可能性的社会空间差异明显扩大,优质教育资源的获取难度显著增加。历史惯性、城市扩张、单位制度和学区制度等均是导致教育资源在空间上和群体间配置差异的重要原因,特别是学区制和市场化配置原则下,经济资本逐渐成为社会群体争夺优质教育资源、实现代际再生产的核心要素,终而形成教育资源、社会阶层和居住空间的互动循环与锁定机制。南京案例在中国大城市中具有代表性,由教育驱动的城市社会空间重构值得持续关注和积极规导,而不断缩小校际教育质量差异则是推进城市内部教育机会和教育质量公平的根本途径。 相似文献

Geography teaching that highlights theoretical perspectives may help develop students’ critical disciplinary thinking, despite foundational knowledge being described to New Zealand geography teachers as ‘not every body's cup of tea’. This article extends the tea metaphor by contrasting two cultivations of theoretical perspectives in school geography. Unlike the two major cultivars of the Camellia shrub, however, this paper argues that perspectives have been minimally grown through one cultivar that focuses on the views of case study individuals and organisations. A maximal cultivation of perspectives is advanced in order to progress school‐aged understanding of the diverse nature of geographical knowledge. 相似文献

城市公共服务设施的供给事关城市居民生活品质和社会公平,基于微观个体行为的公共服务消费特征探讨,有助于从需求角度审视公共服务设施配置的有效性及公平性。以广州中心城区为例,通过问卷调查数据系统分析转型期城市居民的医疗服务消费及社会分异特征,结果表明:广州中心城区医疗服务设施配置对城市居民购房选择的影响弱于公园绿地、教育和商业设施;费用支出、服务态度及技术设备条件决定城市居民的医疗服务消费选择,空间距离作用较小;医疗服务消费出行时间集中在35 min内,出行方式以步行和公交为主;医疗服务消费支出以自费为主,消费评价总体不高。在社会分异上,高收入群体更重视医疗服务口碑和技术设备条件,对费用支出关注程度较低,高收入群体的消费选择偏好区级及以上高等级医疗服务,对公立医疗设施评价最高;而中低收入群体以"自己处理"及选择低等级医疗设施为主;公立医疗服务空间分布相对均衡,民营医疗设施则与中低收入群体更为接近,这与西方城市公共资源分布格局中的"服务反比例法则"不一致。 相似文献

AbstractIn most developing countries, the provision of municipal services and infrastructure invariably fails to match the pace and demands of urbanization. The outcome is often increased informality due to improper planning, official bureaucratic barriers and perhaps insufficient and shrinking public resources, which then makes leveraging private capital for public service provision imperative. Drawing on in-depth qualitative fieldwork in two Ghanaian cities, this paper aims to extend literature on the divergence between service provision and urbanization in developing countries. More specifically, it attempts to qualify recent macro-level data indicating that access to water, sanitation and electricity services in Accra and Sekondi-Takoradi is improving substantively. Contrary to dominant policy narratives circulating in Ghana, we illustrate how the acceptability of key municipal services within urban settings is often inadequate, and how acceptability is tied to spatial and temporal factors. We then identify and examine the reasons underpinning these variations. Through exploring residents’ perceptions of key services, and examining critically the possibility and feasibility of meeting urban service needs through leveraging private resources, this paper contributes to broader academic debates over urban service provision, while also feeding into contemporary policy discussions concerning how to achieve several of the Sustainable Development Goals by 2030. 相似文献

AbstractThis study aims to theoretically investigate the notion of critical thinking for a more just understanding of self and “others” in global geographical learning. It focuses on the kinds of injustice in the world which are driven by our relationships with “others.” By drawing on the literature of critical education, philosophy of education, and geography education, this study reveals how universal notions of criticality tend to easily undermine those perceived as global others and may highlight, in deficit mode, their perceived differences. Instead, the study presents the imperative of deconstructive thinking for a more just world. The article concludes by proposing a teaching strategy for alternative criticality which strives for justice in school geography. 相似文献

The spatial thinking skills and attitudes of geography majors were compared with those of future teachers majoring in elementary education and secondary social studies education. Scores were obtained for each group on two measures: the spatial skills test and the attitude toward spatial thinking inventory. Mean differences were examined based on five factors: major, gender, travel experience, geography courses, and experience using geographic information systems (GIS). For both outcome measures, results showed that the mean scores for elementary education majors were significantly lower than scores from secondary social studies majors and geography majors. Geography majors outperformed both groups of education majors on both measures. Implications for the preparation of geography teachers are discussed. 相似文献

This paper reviews the state of higher education human geography in contemporary Malaysia in relation to four main challenges: defending the unity of identity of higher education geography as a coherent and distinct discipline; ensuring the institutional survival of geography in higher education; enhancing the visibility of geographers as public intellectuals; and fostering the internationalization of human geography in Malaysia. It also suggests possible measures in responding to these. Moreover, while sharing the problems of developing higher education human geography experienced in other countries, Malaysia suffers most from national education policies that place lesser importance on the teaching of geography in schools, that stipulate a non‐English (Malay) medium of instruction, and that have been late in espousing an outward looking research university concept. In summing up the prevailing conditions as depicting a mixed bag of benign contentment, hard‐nosed pragmatism and continuing frustrations, it is uncertain whether recent policy changes to advance research environments in public universities can appreciably alleviate the fourfold challenges mentioned above. 相似文献

空间功能视角下的公共服务对房价的影响——以成都市为例 总被引:1,自引:0,他引:1
房价的快速上涨和城市内部房价的巨大差异引起社会广泛关注,调控房价,防止局部区域房价过热势在必行。本文从城市空间功能的视角出发,以成都市2016年房价为例,基于地理探测器分析公共服务对房价的影响。结果表明:成都平均房价为8480元/m2,并从市中心沿交通环线和放射状干线同时向郊区递减,形成圈层加放射格局,总体上呈现西高东低、南高北低的特点。公共服务(主要包括医疗、金融和教育服务)对房价的影响以第三圈层和西南方最为显著,且高于城市层面上整体的影响。公共服务对房价的影响显著受不同区域的空间功能差异的影响,公共服务和空间功能差异会加剧房价的分异格局,并推动局部房价过热。因此,显著地受到在房价调控中,不仅要有传统的金融、经济政策,还要注重空间功能和公共服务的优化。 相似文献
