Using longitudinal data from Jiangsu Fertility Intention and Behaviour Study (JFIBS) from year 2007 and 2010, this study analyses the fertility intention and behaviour of women who are qualified to have two children from a psychosocial point of view. Based on the Theory of Planned Behaviour, the theoretical framework from fertility intention to fertility behaviour is reconstructed. By observing the phenomenon from the micro-level, the gap between female fertility intention and behaviour and its associated factors are studied. The result shows that, given the situation of being qualified to have two children according to the government's birth control policy, when faced with the choice of whether to have a second child or not, people tend to make their decisions rationally. Attitudes towards fertility, subjective norms, and perceived behaviour control all contribute significantly to the discrepancy between fertility intention and behaviour. In addition, the formation of a concrete birth plan is a major driving force for translating fertility intention into action.  相似文献

Some of the most important features of modern societies are the specialisation of knowledge, the development of technology and its ubiquitous integration in everyday practices. Apparently, the routine use of complex transport, communication and retail systems can only work out as long as a continuous encoding and decoding of spatial information takes place. In this paper different modes of system‐user‐interaction and the involved spatial concepts will be examined. The outcome is a framework of three conceptual types of interaction (or translation) between the geography of the system and the geography of the user's lifeworld. First, the user learns about the internal spatial code of the system to achieve ‘white‐box‐transparency’. Second, efforts in interface‐design show the attempt for ‘lifeworld‐simulation’ by replicating the individual's spatial perception. Third, common geographical imaginations, names of cities, regions or nations, can serve as a ‘third language’ which both the system and the user can refer to.  相似文献

Abstract: This paper interrogates the multiple spatialities bound up with the consumption of units as the dominant means of diagnosing “health‐related” alcohol problems and measuring “drunkenness” in international alcohol policy and research. In order to question the power afforded to units, we work at the intersection of theoretical debates concerning biopower and governmentality; emotional, embodied and affective geographies and actor network theory. Presenting empirical research from the UK we contribute to geographical agendas that seek to consider the ontological and epistemological understandings of alcohol, drinking and drunkenness. The paper concludes by calling for dialogue between social, health and medical scientists in order to develop more pertinent ways of understanding and representing the risks and benefits of alcohol consumption.  相似文献

Using a compiled list of the vascular flora for 21 islands in the western basin of Lake Erie, Preston's resemblance measure and Connor and Simberlof's Null Hypothesis I were applied to native and alien species subsets in order to examine how these findings fit within the equilibrium theory. Based on Preston's measure, it was found that the similarity of species between island pairs was more likely to fit with MacArthur and Wilson's equilibrium theory when native species were considered than when alien species were considered. Native species have restricted distributions - especially those found on the smaller islands - and appear to be less randomly distributed about the islands. This study also found that a large component of the alien flora is widespread in its distribution, and appears to be randomly distributed among most of the islands.  相似文献

Geographers are in a special position to comment on the role of neighbourhood representations in the marginalisation of urban minorities. This paper examines the impact of representations of place on the production of inner‐city youth identities. It argues that the spatial scale of representation is a crucial element in the production of marginal identity, and investigates whether switching scale is a viable option for escaping this identity. Linking the concepts of structure and agency to the notions of ideology and identity, it applies a theoretical argument to empirical contexts of representation and identity formation. Results from semi‐structured interviews with local youths and institutional administrators in an inner‐city neighbourhood of San Antonio, Texas, illustrate how place‐ and scale‐particular ideologies intervene in processes of youth identity formation. While overlying scales of place enables the social exclusion of youths, jumping scales does not empower individuals.  相似文献

Eastern North America in late Pleistocene times was characterized by two major environmental regions: a periglacial tundra or open spruce parkland and an extensive complex boreal/deciduous forest in the unglaciated, lower latitudes. These environments selected for different adaptive strategies on the part of human foraging groups—known archaeologically as Paleoindians. Those in the tundra and tundra-forest region were highly mobile, possibly specialized hunters, exploiting caribou; those in the forest were generalists, exploiting a variety of subsistence resources with a less mobile settlement system. There is little evidence in either area for hunting of Pleistocene megafauna. These differences in adaptive strategies are reflected in the record of sites and isolated fluted points scattered throughout the region, as well as aspects of tool technology, function, and patterns of stone use.  相似文献

道路密度对犯罪分布存在影响已得到大多数学者的证实,但忽略了不同类型道路属性的差异对犯罪的影响。不同类型道路在社会-建成环境等各种属性方面存在较大的差异,因此明确不同类型道路密度对公共空间盗窃犯罪率存在的影响有助于犯罪的防控。基于此,本文以派出所为单元构建多元线性回归模型进行研究。研究发现,不同类型道路密度对公共空间盗窃犯罪率影响不同:城市次干道、城市支路和其他可通车道路密度对公共空间盗窃犯罪率有正向影响;不可通车道路密度对公共空间盗窃犯罪率有负向影响;城市主干道密度对公共空间盗窃犯罪率影响不显著。不同类型道路社会-建成环境的差异是公共空间盗窃犯罪率不同的原因。研究结果可为犯罪精准防控提供指导。  相似文献

国际关系的发展趋势将以经济为主题、以和平合作为主调。相应的地缘关系理论也应作如下调整:从\"争夺霸权\"向\"寻求合作\"的目标转换、从地缘政治向地缘经济的主题转换、从地理位置向科技人才的解释因子转换、从欧洲中心论向全球一体化的空间转换。  相似文献

过滤理论的起源、概念及研究进展   总被引:1,自引:0,他引:1  
过滤是住房的生命周期与家庭的生命周期之间相互作用的产物,包括两大支流:以建立经济理论和模型为代表的关注住房的过滤研究、有关居民迁居的强调家庭的过滤研究。过滤理论的地理学视角可以追溯到霍伊特(Hoyt)的扇形模型,提供了关于居民迁居和城市社会空间结构之关系的解释。过滤理论意义主要有:为低收入群体提供合适住房、解释城市微观和宏观空间变化、分析和解释与住房市场有关的社会问题。过滤理论是中国城市转型研究的新视角。  相似文献
