The ageing baby boomers in Singapore, which account for one-third of the total population in 2006, will have a profound impact on the economy, society and environment. The greatest demand is for health care services. Even though Singapore has generally been regarded as a country where primary health services are easily available to all residents, this paper identifies significant spatial variations across the island-state. In particular, accessibility in some areas with high concentration of boomers is relatively lower compared to other residential areas. This paper concludes that understanding the spatial variation in primary health service accessibility is critical to the success of future policies, which may lead to a review of the provision of such services across the island. The methodology developed in this paper is also applicable to the study of service inequalities in other Asian countries with large rural settings.  相似文献

One can easily use nineteenth-century tithe data of England and Wales in a Geographic Information System (GIS) to analyze a range of subjects, for example, land use, productivity, land ownership, or tenancy. Making the tithe data GIS ready, on the other hand, is a nontrivial matter. The tithe data consist of two main types: spatial, that is, the tithe map, and nonspatial attribute data linked to the map. The tithe therefore has the characteristics of a GIS, albeit in paper form. The author outlines the process of creating the structures for building a data repository that allows the storage and dissemination of both tithe schedules and maps in a single GIS-ready system. The author chose Oracle to host the repository. The Oracle Spatial module allows storage of both spatial and attribute information. Oracle also provides the means of serving data to users via the Internet.  相似文献

Faced with a growing Algerian insurgency in 1955, French Governor-General Jacques Soustelle turned to his ethnological training to convert soldiers into amateur social scientists, hoping to better know the people of Algeria and therefore ease pacification through cultural understanding. Soustelle failed to appreciate the sophistication of revolt in Algeria, a diverse array of movements that did not fit traditional European categories. Confronting similar problems in understanding the causes of Iraqi and Afghan resistance in the years following the invasions of 2001–2003, American military planners also turned to anthropology. Though not taken to the administrative extreme seen in Soustelle's Algeria, the United States Army instituted the Human Terrain System in order to better understand native populations involved in an active insurgency. American planners can learn from the French experience by developing a more nuanced approach to study that includes more advanced anthropological techniques without the baggage of the colonial system.  相似文献

纵观现有旅游地环境承载力理论与应用研究,成果主要集中在从不同角度对其概念、量测指标体系及在旅游管理与规划领域的运用进行探讨,其阈值量测则以静态极值为主,且个案居多,表明学界尚未形成统一的理论研究范式与共同纲领。更为重要的是,旅游地合理承载力阈值研究仅作为概念获得共识,定量分析尤显不足。基于上述原因,本文从复杂系统理论出发,在深入分析旅游地环境承载力与生命周期之间耦合关系的基础上构建了旅游地动态演化模型及其理论研究框架。该研究一方面为探寻旅游地环境承载力理论提供一种新思路,另一方面解决了环境承载力合理阈值量测这一旅游地可持续发展的核心问题。  相似文献

随着户外游憩研究的不断深入,获取有效游憩行为和环境信息的重要性突显,美国学者麦肯奇(McKenzie)研创出社区玩耍与游憩观察系统方法(System for Observing Play and Recreation in Communities,SOPARC)能够瞬时批量高效获取户外游憩活动信息,因而在西方游憩行为研究中逐步获得广泛运用。本文使用文献检索和文献分析法,通过查阅和分析近年西方学者对社区玩耍与游憩观察系统方法的主要应用成果,归纳出西方学者对SOPARC应用研究的热点。通过西方学者应用SOPARC方法研究的特点评述,提出该方法对我国研究的若干启示:SOPARC方法科学有效,能够为我国游憩研究提供技术支撑,但引入应用需要根据中国国情进行改进;SOPARC方法应用广泛,可主要用于游憩行为调查、游憩设施和环境规划及游憩地管理中。  相似文献

北魏均田制下产权制度变迁分析   总被引:1,自引:0,他引:1  
杨勇 《史学月刊》2005,(8):25-30
结合新制度经济学的有关理论,对我国历史上的均田制进行分析是很有意义的。作为国家强制性的制度变迁形式,均田制依靠国家的力量得以推行,为国家建立税收基础,以实现国家租金收入的最大化。但是,在均田制实施的过程中,却遭遇到了来自下层的变通与退出力量,使得均田制度的演进过程又呈现出既定利益结构下的诱致性变迁。  相似文献

20世纪末期美国政府在文官考核制度方面进行了理论创新与实践探索。从单一的判断功能向多元复合功能的转变,从依据长官的主观评估向依据雇员与长官及同行多重评估的过渡,是这一时期美国政府文官考核制度中出现的新变化。这一变化对提升文官的素质、提高政府的效率产生了影响。  相似文献

Analysis of plant microfossils (pollen, phytoliths, starch grains and xylem cells) was carried out on 12 soil samples from a variety of pre-contact archaeological features in South Kona within a portion of what has been termed the Kona Field System, on the Island of Hawaii. The oldest radiocarbon ages of the sampled deposits are 1300–1625 AD and 1310–1470 AD. The pollen and phytolith evidence suggests a change from more to less trees and shrubs in the area as a result of human activity. We found phytoliths of banana (Musa sp.) leaves in most and starch grains and xylem cells of tuberous roots of c.f. sweet potato (Ipomoea batatas) in all of the samples, suggesting that the sampled features were associated with these crops and that both crops were cultivated intensively within the study area. Higher concentrations (volumetric) of starch and xylem in samples from older deposits suggest that cultivation was more intensive then. The apparent absence of starch and xylem remains of other tuberous crops archaeologically identified elsewhere in Polynesia suggests that tuberous cropping within the study area was mono-specific.  相似文献

晋代墓葬制度与两晋变迁   总被引:1,自引:0,他引:1  
晋制是继周制、汉制之后,中国古代墓葬制度发展演变的重要内容,考古学意义上的晋制与晋礼的制定关系密切,晋礼制定、施行的过程反映了汉魏晋社会的变迁。洛阳是西晋的都城,都城洛阳晋墓中的洛阳因素代表的墓葬制度内涵应该与西晋制订推行的新礼有关,洛阳因素反映的墓葬制度即为继汉制之后的晋制。东晋时期在都城建康地区逐渐形成建康因素,洛阳因素与建康因素是两晋时期墓葬制度的主要文化内涵。  相似文献

意大利文化遗产风险评估系统概览   总被引:2,自引:0,他引:2  
意大利文化遗产风险评估系统用于管理文化遗产保护过程中有关遗产降解退化因素的相关技术数据,为相关科学研究和规划管理提供信息支持。其设想始于20世纪70年代,90年代该系统发展成一个科学化、规划化的体系。通过风险评估系统制定的方针可对意大利建筑和考古遗迹进行科学保护、长期维护和及时修复。在风险评估系统中,意大利创建了以GIS程序数字地图为核心的中央枢纽,对考古和建筑遗迹进行了前期调查工作,未来还将不断完善和进行防灾减灾的深入研究。  相似文献
