This article compares multivariate spatial analysis methods that include not only multivariate covariance, but also spatial dependence of the data explicitly and simultaneously in model design by extending two univariate autocorrelation measures, namely Moran's I and Geary's c. The results derived from the simulation datasets indicate that the standard Moran component analysis is preferable to Geary component analysis as a tool for summarizing multivariate spatial structures. However, the generalized Geary principal component analysis developed in this study by adding variance into the optimization criterion and solved as a trace ratio optimization problem performs as well as, if not better than its counterpart the Moran principal component analysis does. With respect to the sensitivity in detecting subtle spatial structures, the choice of the appropriate tool is dependent on the correlation and variance of the spatial multivariate data. Finally, the four techniques are applied to the Social Determinants of Health dataset to analyze its multivariate spatial pattern. The two generalized methods detect more urban areas and higher autocorrelation structures than the other two standard methods, and provide more obvious contrast between urban and rural areas due to the large variance of the spatial component.  相似文献

Regarding illicit drugs as a nontraditional security challenge (NTS), the Chinese state deploys a policy package combining coercive crackdown and development assistance to start transnational narcotics control in the Golden Triangle—the notorious illicit opium-producing area between Myanmar, Laos, and Thailand. This paper examines how illicit drugs are framed as a security challenge and how the state works with other forces to implement transnational narcotics control. Specifically, I focus on the Chinese state's efforts to implement transnational narcotics control in the notorious illicit opium-producing areas in northern Laos and Myanmar. My analysis draws first on the Copenhagen School's work on securitization, that is, how certain discourses are deployed to dramatize and present an issue as a security challenge requiring supreme priority. Then I situate drug trafficking in the tension between the territorial logic of national sovereignty and the transnational logic of NTS challenges in order to analyze the Chinese state's policy of narcotics control in the Golden Triangle. Through this analysis, I seek to underscore the longstanding but underdeveloped theoretical recognition of illicit drugs as a global commodity and an NTS challenge. The nexus of territorial sovereignty and extraterritorial subsystems spells out a new direction to understand NTS challenges in general and illicit drugs in particular.  相似文献

This study uses GIS-based spatial network analysis (SNA) to simulate patterns of foot traffic and analyze the manipulation of the built environment of a small Inka imperial outpost that became an early Franciscan doctrina (doctrinal settlement) in the Andean highlands of southern Peru. Excavations show evidence for growth and remodeling of the site's public and domestic spaces over its short use life as a doctrina, pointing to an increasingly orthodox regime of indoctrination. The results of SNA-based walking simulations show specifically how movement through the site was rerouted to isolate the old Inka ceremonial core, producing new rhythms of interaction and directing public processionals to the colonial plaza and chapel of the doctrina. The complementarity of SNA with other established forms of access analysis and its broader utility for archaeological research design, sampling strategies, hypothesis testing, and interpretation are discussed.  相似文献

A second Greek-inscribed sherd mentioning Soteles the Athenian was discovered in stratified context during the excavations at Failaka (ancient Ikaros), Kuwait. It gives a short list of three Greek personal names, Soteles, Dionysios and Agatharchos. It also provides a secure date for the activity of this Seleucid officer in the first half of the third century BC. The other sherd pertaining to Soteles is re-examined. Both were parts of inscribed vases offered to the deities of the temples inside and outside the fortress, during the process of settlement of the first Greek garrison.  相似文献

Les couples à double emploi, c'est-à-dire ceux où chacun des conjoints occupe un emploi rémunéré, posent d'em-blée la question des liens entre les rapports hommes-femmes et les rapports entre classes sociales (Bonney 1988). Ces couples doivent négocier quotidiennement les effets locaux des rapports structurels de travail et de pouvoir entre hommes et femmes, et souvent trouver des aménagements nouveaux qui, à terme, modifient ces rapports structurels (Le Bourdais, Hamel et Bernard 1987; Ross 1987).  相似文献

Spatial Modeling of Poverty in Montréal: Methodological Contribution of the Geographically Weighted Regression
The Island of Montréal is particularly concerned with the issue of poverty. In 2000, 29 percent of its inhabitants lived under the low income cut-offs as defined by Statistics Canada. However, poverty is not a homogeneous phenomenon at the intra-urban scale, and identifying and categorizing spaces of poverty has become a main concern for ongoing researches. According to this way of thinking, this paper proposes an analysis of the factors influencing the geographical distribution of poverty on the Island of Montréal. To be able to identify properly the various profiles of poverty, this analysis uses a specific methodology, the geographically weighted regression (GWR), and compares its results with the ones of a classical regression model. At the global level, the most important factors to explain poverty are in order: unemployment, lone-parent families, one person households, recent immigrants, part time or part year workers, school dropouts. At the local level,  相似文献

This article argues that measures designed to improve the availability and accessibility of information as a key strategy to facilitate development have become ends in themselves, de‐linked from their potential to have an impact on Southern knowledge systems that may lead to improved development outcomes. The production and dissemination of ever‐greater volumes of information in response to concerns about the uneven availability of information, particularly for individuals and intermediaries based in the global South, are unable to address the persistent problem of the fragmentation of knowledge systems that result from knowledge for development (K4D) initiatives in which information and knowledge are treated as isolated entities. The article presents the findings of a study into the K4D practices of a network of women/gender information intermediaries. It reveals that attempts to strengthen Southern knowledge systems are forestalled by efforts that merely improve the supply of information rather than engaging with knowledge processes in their entirety, thus limiting their potential to promote improved development outcomes. Proxy measures of success are used that fail to challenge the typically neoliberal underpinnings of the dominant knowledge infrastructure. The author concludes that, if knowledge‐based development interventions are to be made more effective, K4D stakeholders need to find ways to engage not just with the supply but with the demand for information, as part of broader efforts to strengthen entire knowledge systems in ways that take account of concerns around hegemony.  相似文献

L'information devient de plus en plus un enjeu crucial pour les institutions et acteurs engagés dans des processus territoriaux de développement. Comme la littérature sur les NTIC le démontre, l'accès a l'information concernant leur environnement global (sources de capitaux, tendances globales, débouchés, encadrement) ainsi qu'à celle concernant leurs atouts locaux et spécifiques (ressources humaines, physiques, financièrs et institutionnelles, identités, possibilités de mobilisation) fournit des indications indispensables pour faction des collectives locales engagées dans des projets de développement. Cependant, ce qui est souvent négligé c'est que le processus même par lequel cette information est produite et diffusée constitue en soi un facteur intervenant dans l'orientation que prend le développement. L'information marque les territoires concernés. Aussi est-il essentiel de construire des inforoutes permettant la participation des collectivités à la production de l'information qui les concerne. L'Atlas du Québec et de ses régions est une expérience qui vise cet objectif. Dans ce texte, nous présentons l'état d'avancement et les conclusions préliminaires de cette expérience. Information networking is a crucial issue for organizations and socio-economic actors. As the literature on development shows, information at the global level (financial perspectives, global tendencies, markets, and regulations), as well as at the local level (demographic and social characteristics; human, physical, economic, institutional, and organizational resources; specific assets; quality of life; etc.) is indispensable to local collectivities involved in development projects. Nevertheless, often overlooked is the fact that the very process by which this information is produced and disseminated has a significant effect on the direction of development. Information has an impact on the local community. There is a need for building territory information networks that allow local communities to produce the information that concerns them. This paper presents first a global survey of globalization and the effects of information highways on specific territories, and second, an experiment in progress about building a territory information network in the province of Québec, the Atlas of Québec and Its Regions.  相似文献

Based on the case of the Mohawk territory of Akwesasne, wedged between Ontario, Quebec, and New York state, this paper provides an analysis of the links between the affirmation of indigenous culture and the implementation of security policies on borderlands. The focus extends beyond political conflicts over border issues to encompass the ways in which Aboriginal sovereignty is affirmed within processes of negotiation and cooperation in the matters of identification requirements, border agents’ cultural sensitivity, and law enforcement. We find that the enhancement of border security can paradoxically be a political opportunity for local leaders to reaffirm indigenous sovereignty, and that this reaffirmation through cooperation is, at the same time, emerging as a key factor in the implementation of border security policies.  相似文献
