Using data from Canada’s General Social Survey, this article assesses ethno-racial differences in social trust. Bivariate findings reveal that the three most culturally distinctive minorities—visible minorities, the French, and Indigenous Peoples—exhibit the lowest trust of all groups. Multivariate analyses show that controls for “ethno-cultural markers” (religion, language, immigration status), socioeconomic influences (education, income), and social engagement indicators (voluntary association activity, ethnic diversity of friendships) explain the lower trust between the French and, less so, among visible minorities. Socioeconomic factors partly account for lower trust among Indigenous Peoples, but they still express comparatively low social trust even with controls. The article discusses how interpretations focusing on “social distance” and “social boundaries” processes help in understanding social trust differences across Canada’s major ethno-racial communities.  相似文献

This article explores the securitisation of water aimed at avoiding a political crisis for the Chun Doo-Hwan regime in South Korea (1979–1988) using the case of the Peace Dam. The legitimacy of the Chun regime was vulnerable because of diverse factors such as internal and external crises inherited from the previous regime and Chun’s rise to power through a military coup and civilian massacres. In this political situation, the securitisation of nature could be an effective method of curbing potential resistance and ruling a people facing a complex crisis. The constructed threat of an attack by flooding by North Korea and the consequent alleged need for the Peace Dam were part of a scheme by Chun to maintain political power through the securitisation of water, specifically by establishing North Korea as an external enemy and unifying the South Korean people.  相似文献

This article focuses on the public movement education practices of a group of middle-class, Korean dance instructors at the Korea Laban Movement Institute (KLMI), a recently established civil institution in Seoul, South Korea. The KLMI classes promote self-directed and well-rounded Korean bodies through student-centered and egalitarian movement instruction. In recent years, these classes received public funds from the culture and arts foundations supported by the state’s cultural policies, as well as attention from Korean public media. This research introduces the public movement education practices that have aligned well with the state’s early twenty-first century cultural policies by making culture and arts education more accessible to the average Korean. In addition, the study shows the broader impact of KLMI’s public movement education practices, which have merged into the political and social landscapes of contemporary South Korea.  相似文献

The paper examines the significance of state territoriality and the related multi‐scalar practices of the state in the light of the symptoms of post‐politics exemplified in global environmental governance. The focus rests on the South Korean government's Green Growth (GG) strategy and the efforts to export this strategy as a role model to emerging economies worldwide through the establishment of the Global Green Growth Institute. We begin with the question why the Korean government is going global with a political program that is heavily disputed at home. We then study the practices by which the state manages to maintain its territoriality under the conditions of global climate change. Lastly, we discuss how multi‐scalar practices of environmental governance in the GG strategy are applied by state and non‐state actors both in Korea and abroad.  相似文献

ABSTRACT. Löschian duopoly under heterogeneous cost conditions is examined to show that it is not equivalent, contra past findings, to spatial collusion. Moreover, within the confines of the assumed demand and cost conditions spatial collusion is shown to be superior to Loschian competition in terms of both (aggregate) consumer surplus and producer surplus, which implies a possible welfare gain from collusion. A general, if not the general, prices-and-welfare comparison of alternative pricing schema including collusive, Löschian, and optimal pricing is summarily presented in a table.  相似文献

The main objective of this study was to analyze spatially and temporally groundwater level changes using geographic information systems and spatial analysis with respect to urban development, groundwater withdrawal, and groundwater recharge potential. The study focused on Waukesha County in southeastern Wisconsin, where urban development has been accelerating while groundwater has been declining over the last several decades. We analyzed data about groundwater withdrawal, groundwater level, land use/land cover, and precipitation utilizing correlation analysis, geographically weighted regression, land use change analysis, and map overlay. Our findings include the following: the extent of urban areas expanded faster in regions with high recharge potential than in those with low or moderate recharge potential; the correlation of urban growth with groundwater level is highly variable over time and space; and changes in groundwater level are strongly related to the spatial distribution of groundwater withdrawal. The study pinpointed the need to consider the spatial unevenness of groundwater withdrawal in understanding the changes in groundwater level and groundwater recharge potential for better management of groundwater resources. Un análisis espacio‐temporal de los cambios de nivel de aguas subterráneas en relación con el crecimiento urbano y de las aguas subterráneas de recarga para el Condado de Waukesha, Wisconsin El objetivo principal de este estudio es analizar espacial y temporalmente los cambios del nivel de aguas subterráneas utilizando sistemas de información geográfica (SIG) y análisis espacial con respecto al desarrollo urbano, la extracción de agua subterránea, y el potencial de recarga. El área de estudio es el condado de Waukesha, en el sureste de Wisconsin, donde el desarrollo urbano se ha acelerado mientras que las aguas subterráneas han disminuido en las últimas décadas. Se analizaron los datos sobre la extracción y nivel de aguas subterráneas, la cobertura vegetal/uso del suelo, y la precipitación utilizando un análisis de correlación, una regresión ponderada geográficamente (geographically weigted regression ‐GWR), un análisis de cambio de uso del suelo, y la superposición de mapas (map overlay). Los resultados muestran que: (1) la extensión de las zonas urbanas se incrementó más rápidamente en regiones con alto potencial de recarga que en áreas con potencial de recarga de bajo o moderado; (2) la correlación entre el crecimiento urbano y el nivel de aguas subterráneas es muy variable tanto temporal como espacialmente; y, (3) los cambios en el nivel de aguas subterráneas están fuertemente relacionados con la distribución espacial de las actividades de extracción del recurso. El estudio identificó la necesidad de considerar la irregularidad del patrón espacial de la extracción de aguas subterráneas con el fin de mejorar la comprensión de los cambios en el nivel y el potencial de recarga y así promover una mejor gestión de los recursos hídricos subterráneos. 本研究主要目的在于通过地理信息系统(GISs)和空间分析的时空视角,对城市发展的地下水水位变化,地下水开采和地下水潜在补给进行分析。本文研究区为威斯康星州东南部的沃基肖县,该区在过去近几十年里城市快速增长而地下水急剧减少。通过地下水开采、地下水水位、LUCC(土地利用/土地覆盖LULC)和降水的数据分析,采用方法包括相关分析、地理加权回归模型(GWR)、土地利用变化分析和地图叠加分析。研究结果包括:(1)高地下水补给的城市地域范围的扩大幅度快于中等或低补给地区;(2)城市增长与地下水水位的相关性在时间和空间上是高度变化的;(3)地下水开采的空间分布与地下水位的变化呈强相关。研究精确地指出,为更好管理地下水资源,在理解地下水位变化和地下水潜在补给时需考虑地下水开采的空间不均匀。  相似文献
