This paper describes a system of versatile software packages that has been developed by the author for population analysis on IBM-compatible microcomputers using PC or MS DOS. The series includes programs for the production of life tables, the analysis of spatial patterns and temporal trends in mortality, population projections, stationary-state population simulations and demographic planning, cohort survival estimates of net migration, and the analysis of migration matrices. Each of the programs in the series is discussed in terms of its principal analytical features, associated conceptual and methodological issues, and potential applications. The programs are intended for use both as basic research and planning tools and as instructional aids in university-level courses. The programs and related documentation are available on a set of four 360K diskettes.  相似文献

Most discussions about the impact of Afghanistan on the future of NATO focus on transatlantic relations between the United States and the European Union. But for Canada, which is one of the few NATO allies that voluntarily deployed into the south, facing heavy resistance and fighting from Taliban insurgents, the Afghanistan operations have become the most salient dimension of its continued involvement in the Atlantic Alliance. While this may seem surprising, given the cutbacks in Canadian defense spending in the 1990s and the withdrawal of Canada's standing forces from Germany, it should not. For during that so-called dark decade, Canada continued to make major contributions to NATO and European security. This essay argues that Ottawa's multi-faceted military and political support of the “new” NATO of the post–Cold War era continued when the alliance undertook its involvement in Afghanistan. Indeed, in its efforts in support of NATO's mission in Afghanistan, Canada has demonstrated a dedication to the alliance that seems stronger than NATO's collective commitment to itself.  相似文献

The emergence of a mega-mall - with its increased scale, size, and ensuing annexation of much of a city's retail and social life - intensifies the need for research about the social functions of shopping centres. Profiles of mall social life are necessary to understand the larger geographical, legal, political, and social issues accompanying the proliferation of such privately owned, publicly used indoor urban environments. Social interaction at West Edmonton Mall (wem) is characterized through an examination of its physical design and operation and an assessment of attitudes and uses of its local patrons, including adolescent 'ma/ies. wem is not as successful in orchestrating visitor satisfaction as one might expect, due partly to the amplification of tension between mall owners I designers and the desire of local residents to engage the mega-mall on their own terms.  相似文献

社会资本对区域经济增长的影响是通过对区内企业、产业集群及区域整体等三个不同主体的影响发挥作用的。在企业由传统成长模式向网络化成长模式转变,产业集群由聚集经济向创新网络转变,区域由空闻结构向网络社会转变的过程中,社会网络及内含资源起着决定性作用。社会资本对三者的作用体现空间上的层次递进特征,即依循企业、集群、区域三个不同主体网络化递进发展的“织网模型”,依次由“发散状企业网络”向“经纬状集群网络”再向“多构面区域网络”发展的织网过程。社会资本及社会网络对企业的作用是摄取关键资源、信息等;对产业集群的影响是建立学习与创新机制、成本节约机制、形成合作竞争氛围;而对区域的积极意义是保持区域良好的信任文化。  相似文献

北京市低收入社区社会融合的多维度测度与影响因素分析   总被引:1,自引:0,他引:1  
在快速城市化的背景下,城市低收入社区群体的社会融入问题逐渐成为城市包容性发展的桎梏。基于北京市典型低收入社区的实地调查数据,本文运用探索性因子分析对城市低收入社区群体社会融合结构和现状进行探讨,并对影响城市低收入社区群体的社会融合状况进行实证分析。研究发现调查城市低收入社区群体的社会融合主要受到心理融合、经济融合、环境融合、社区关系融合4个维度影响,社区关系融合、环境融合、经济融合和心理融合程度表现出依次降低的倾向,且居民的社会融合总体水平偏低。从影响因素来看,低收入社区群体的社会融合主要受个体因素、家庭因素、就业因素和住房因素的影响,不同维度社会融合程度的影响因素也有所差异。  相似文献

Summary. A chronological and spatial analysis of Mycenaean tomb types is presented in the belief that burial practices reflect the social and political changes which occurred during the Late Helladic period. Interpretation of the evidence is complicated by the degree of regional diversity. However, it is suggested that the practices of the Middle Helladic period were not as simple as has been supposed and foreshadow the innovations of the early Mycenaean period which were inspired by political motives. The increasing standardisation in tomb types in LHIII was conditioned by the emergence of the Mycenaean palace system, the collapse of which engendered the changes seen in LHIIIC.  相似文献

选择1949年以来以北京为主要描述对象的118首华语流行歌曲为研究素材,以歌词中的主要词汇构建共现网络,采用社会网络分析法进行整体网络指标、节点中心性、核心—边缘模型和社区检测分析。研究发现词汇共现网络呈现出“核心+半边缘+边缘”的圈层结构,以核心区词汇所呈现的物质空间和社会心理两个维度的意象元素认知为主,半边缘区词汇充分拓展地方意象内容,边缘区词汇进行具体歌曲的个性化表达。通过社区检测可以将北京城市歌曲中的地方意象归纳为强政治性、显地方性、高象征性、泛世俗性4类特征,在歌曲的演唱视角、歌词内容、曲调旋律、情感表达、创作话语权等方面得以体现,并且存在时间变化特征,从而反映了一定话语环境下地方意象的生产与变化。  相似文献

The concept of social capital is widely perceived as a promising tool for explaining differences in economic development between countries and regions. According to this theory, weak links (bridging social capital) and social trust in an area favour its better access to other forms of capital, that is, economic and human capital. However, strong links (bonding social capital) may stifle creativity and entrepreneurship. Since the vast majority of research on the impact of social capital on economic development focuses on highly developed Western European countries, it seems particularly interesting to evaluate the usefulness of this approach when applied to post‐communist countries with their different experiences. The objective of this article is to identify the spatial variation of different forms of social capital in regions of Poland and then to test a hypothesis on the impact of this capital on regional economic development. The results demonstrate that despite the existing differences between regions there are no significant relationships between levels of social capital and economic development. This may be explained either by low social capital levels or by the overall degree of Polish economic development.  相似文献

Insights from social system–environmental system coevolutionary thought experiments are abstract, mind opening, and can only be conveyed by leading readers through the experiment themselves. Undertaking applied coevolutionary analyses requires one to bound processes and fix some of the categories, contrary to the nature of the broad, opening nature of coevolution itself. Being conscious of these contradictions makes it difficult to engage in a sustained research programme or form a community of coevolutionary scholars. In this article we engage with the epistemological tensions of conducting coevolutionary research and put forward tentative strategies for managing them.  相似文献

本文基于2017年北京市居民日常活动与满意度调查数据,运用多层次路径分析方法,以社区及周边环境作为地理背景,探讨邻里环境、社区交往和生活满意度之间的复杂关系.研究发现,在控制个体和家庭社会经济因素后,社区建成环境对生活满意度的直接效应较弱,仅公园可达性显著正相关.然而,建成环境通过社区交往对生活满意度的间接效应显著,尤...  相似文献
