Measuring the spatial correspondence among geographic features is an important component of many analyses such as those seeking to identify similar or dissimilar features, explore the extent to which change has taken place, and explain the processes influencing spatial change. In networked systems, the paths providing connectivity between pairs of nodes are often the geographic features among which spatial correspondence is to be assessed. That is, given a set of paths between a pair of nodes, the extent to which they share portions of the network and spatially deviate from one another can provide insight on the factors underlying the use of a system. While methods for measuring the spatial correspondence among specific types of network paths have been devised, this article proposes a methodology for measuring the spatial correspondence among the topology of network paths of any type, including those involving redundant use of network space. By basing comparisons upon the topologic relationships among the paths, the proposed approach better accounts for average spatial deviation as well as the asymmetric spatial relationship between pairs of paths, enabling greater stability and consistency in the analysis of their spatial characteristics. The developed methodology is applied to evaluate variability in spatial correspondence among a set of network paths to demonstrate its utility.  相似文献

Rural places are discussed in terms of predominantly farming communities, nonfarm communities and places with mixed functions. In the case of farming communities, Soviet policy is to encourage consolidation to optimal sizes of 1000 or 2000 people, to make possible better services than can be extended to single-dwelling and other very small settlements. An increasing share of nonfarm settlements among rural places reflects the operation of three kinds of processes: the appearance of places related to nonfarm use of the territory (mining, transportation, recreation, etc.); the transformation of rural places, especially in suburban zones into dormitory settlements; and the development of small-scale local industry.  相似文献

中国乡里制度研究的路径--读《中国乡里制度》   总被引:1,自引:0,他引:1

由于史料过于零散、缺乏,乡里制度本身缺乏规范性、完整性和系统性,又同赋役制度、宗法制度错综复杂地交织在一起,所以,中国古代乡里制度研究的深化,有待于在研究的资料、视角、理论和方法等方面取得新的突破。赵秀玲著《中国乡里制度》一书,在这几个方面都有有益的探索和尝试,但却留下了不少遗憾和可供商榷之处。  相似文献

智慧博物馆是传统实体博物馆发展到一定阶段所产生的一种新的博物馆高级形态,具有主体的人本性、资源的整合性和数据的再生产性等基本特征。与数字博物馆相比,智慧博物馆的"智慧化"主要体现在数据来源的多样性、数据传输的多向性和数据交换的普遍性上。建设智慧博物馆需要警惕走入载体离心化、技术泛滥化、内容娱乐化、数据固态化和建设盲目化的误区,抓住"数据"这一核心要素,围绕数据生成、数据加工、数据运用和数据共享诸环节,科学系统地推进展开。  相似文献

New York, Los Angeles, and Miami are primate immigrant centers within the U. S. metropolitan system, attracting new immigrant arrivals as well as serving as focal points for internal migrants. Using the segmented assimilation framework as a foundation, this paper emphasizes the role of geography and migration within the assimilation process. Focusing upon selected origin groups, migrant selectivity and the determinants of migration are evaluated and compared, highlighting the differential role of primate centers. While the New York and Miami metropolitan centers clearly dominate Dominican and Cuban migration systems respectively, the role of primate centers is less clear among other national origin groups.  相似文献

Comparing degrees of religiosity, Canada and the US have been moving along divergent trajectories for the past several decades. Regional variations are evident in both societies, but, taken as a whole, the divergence holds up even when these intrasocietal differences are accounted for. Neither the classic secularization thesis nor the more popular religious economy model in the sociology of religion adequately explain the contemporary disparities in religious practice and belief in the two societies. More compelling explanations lie in human security and welfare state models. Canadian and US demographic patterns, particularly internal differences among recent immigrants, are additional explanatory factors. Levels of existential security and immigration trends in the two societies are likely to sustain the divergence in religiosity.  相似文献

Abstract. Since the First World War, grants of territorial autonomy have been a widespread means by which regimes of diverse ideologies and political cultures have attempted to address the demands of regional cultural communities within their borders. Cantonisation, or asymmetrical decentralisation along territorial-cultural lines, has been a common form of territorial autonomy employed by these states. Yet, despite its importance, little is known about whether and why such cantonisation measures have helped or hindered the search for peace and stability in culturally heterogeneous states. Part of the answer lies in analysing the historical-political contexts, or historical paths, by which cantonisation arrangements have emerged. Comparative analysis identifies five such paths: international settlements; state-building; democratisation or transitions from authoritarian rule; democratic maintenance; and decolonisation. Each of these paths poses distinctive problems for the evolution of the cantonisation arrangement.  相似文献

Abstract

The aim of this article is to shed some light on issues of territorial development and of rural development and to identify what links and opposes them. Indeed, everything pushes towards joining these two dimensions, which for a long time seemed disconnected. On the one hand, the policies targeting rural areas explicitly include the territorial dimension, while the distinction between rural and urban is getting blurred. In the meantime, decentralization, subsidiarity, the regionalization of agriculture, short circuits and local foods take place in parallel with the generalization of an urban model. Finally, we find that regional sciences are paying increasing attention to rural and agricultural dimensions, while studies concerning rural questions are starting to consider territorial issues. The first section of the article provides a critical presentation and attempts to define and distinguish the notions of development, territory and the rural. The second section addresses questions of regional and territorial development by presenting the main theories and public policies and concludes with a discussion about the possibilities of reconciling the theories and the policies. The third section follows the same structure, applied to the question of rural development, from analyses to grass-roots policies.  相似文献

Urban displacement is receiving growing visibility within urban studies. However, most literature centres on the logic of late capitalism and tends to neglect colonial history and local resistance to displacement. This paper takes an alternative path: it relates (a) the history of colonialism and ethnic cleansing of the city of Jaffa with (b) the present-day gentrification and displacement caused by neoliberal urbanism. To unpack this entanglement, the article focuses on political city walking tours led by Internally Displaced Palestinians in Jaffa, alongside a broader repertoire of urban subaltern tactics to reclaim it—ranging from community meetings to more overtly politicised acts of protest and initiatives to disrupt gentrification. The article therefore advances debates on urban displacement and urban citizenship mobilisation through the lens of post-colonial theories, and by adopting a participatory interdisciplinary approach—from a novel perspective that centres local knowledge, lived experiences, and grassroots activism.  相似文献

East Asia and the Asia–Pacific are core components of the global economy, and there have been important recent developments in the regionalism of both regions. After the 1997–1998 financial crisis, East Asian countries initiated more exclusive regional cooperation and integration ventures mainly through ASEAN Plus Three, but lately this process has stumbled. The Asia–Pacific Economic Cooperation (APEC) forum has also failed to make substantial progress. Attention has instead increasingly turned to free trade agreements (FTAs), yet these have hitherto been overwhelmingly bilateral in nature. There are still only a few truly regional FTAs in East Asia and the Asia–Pacific—and these are on a sub‐regional scale. However, various frustrations over the messy and fractious pattern of heterogeneous bilateral agreements led to the recent initiation of ‘grand regional’ FTA talks. The Trans‐Pacific Partnership (TPP) is an Asia–Pacific‐based, United States‐led project while the Regional Comprehensive Economic Partnership (RCEP) is an East Asia‐centred project. Each contains highly diverse memberships and the successful conclusion of TPP and RCEP talks is not assured. It is argued that, if negotiated, the RCEP is more likely to advance meaningful and effective regionalism than the TPP due to the former ascribing more importance to regional community‐building. Furthermore, bilateral FTAs already in force may over the long term transform into more comprehensive economic agreements that address new regional and global challenges such as energy security and climate change.  相似文献

This paper builds on some previous results concerning: (1) a view of the industrial district as a learning region, and (2) a typology of features of local development and industrial policies. The aim here is to apply these results to a 'non-district' case study, that is the understanding of the inner logic of the economy and the framing of the local economic policy in an Italian dynamic city (Florence, and its urban system). The interest of such case is two-fold. Firstly, we see how the conceptual framework developed for the analysis of industrial districts can be applied, at least partially, to different types of local systems, and in particular to the important case of complex and dynamic urban systems. Secondly, the complexity itself makes easier, or not avoidable, the consideration of a trade-off in the inputs of local policy's relevance.  相似文献
