1971年印巴危机是冷战时代一次具有重大国际影响的地区危机。危机期间,因受东巴内战与印巴冲突的双重影响,大量东巴居民逃往印度,沦为难民。东巴难民持续涌入印度不仅是东巴危机转变为印巴危机的主要诱因,同时也是导致南亚持续紧张、敌对氛围难以消解的重要根源。为妥善解决难民问题,美国积极谋划,投入大量人力、物力、财力,意图妥善解决难民问题,化解危机。但是美国采取的积极措施并未减缓危机冲突的不断升级。在处理难民问题的过程中,美巴政策协调趋于一致,而印度与美巴在难民问题上的政策倾向却渐行渐远。归根究底,是否应该在难民问题上附加最终促成东巴独立的政治条件是美巴与印度的根本分歧所在。而这一根本分歧的悬而未决最终成为引爆第三次印巴战争的导火索。  相似文献

This article presents results of non-destructive Schmidt hammer tests performed on ancient fired clay bricks sampled from historical masonry. These tests were carried out in order to evaluate, and compare, the different degrees of degradation, depending on the bricks’ specific exposures and locations within a wall. The results indicate that this technique is sensitive enough to distinguish sample locations and measure weathering differences, even for different surfaces of a particular sample. For each case study, referenced surfaces were tested for bricks from a facade or interior wall. Each surface was tested with a Schmidt hammer type LB at ten different points of measurement, and these measurements were repeated ten times. For each impact at a particular point, a mean rebound value was calculated to provide an index of the degree of brick-surface microweathering.  相似文献

全球—地方关系为产业创新研究提供了新的视角。本文基于全球(通道)—本地(蜂鸣)关系视角构建了软件产业集群创新效应研究的理论框架。以西安市软件产业集群为例,采用Stata13定量分析不同尺度创新合作的创新效应及其影响因素。研究发现,本地和国际创新合作均对集群创新具有积极的影响,且后者比前者的创新效应更强,说明搭建外部通道对集群创新的必要性;本地与国际创新合作交互对不同规模的软件企业产生的创新效应不同,对小型软件企业存在减法效应,对中型软件企业存在加法效应,对大型软件企业具有乘法效应。建立领先软件企业带动的开放创新系统,是西安市软件产业集群提升创新效应的有效路径。  相似文献

This article develops the concept of “urban frontier” to explore conflicts over state regularisation of city edge informal settlements in Zimbabwe’s capital Harare. It conceptualises the presence of “lawless” urban frontiers and “illegal” territorial authorities in capital cities as expressions of a permissive form of central statecraft. In so doing, the article takes forward debates over the politics shaping the margins of Africa’s rapidly expanding cities, redressing scholars’ tendency to neglect central party‐state strategic calculations and party politics in their analyses of unregulated settlements. Dominant interpretations generally hinge on state absence or weakness and emphasise localised influences. The case of Harare’s highly politicised city‐edge informal settlements reveals the inadequacy of apolitical approaches particularly clearly, as all were controlled by the ruling ZANUPF party. The conflicts provoked by regularisation provide a lens on disputes within the ruling party, which we interpret as disputes over different forms of clientalist statecraft. Analyses of urban frontiers can thus help move away from generic one‐size‐fits‐all explanations of informality and patronage politics in Africa’s expanding cities.  相似文献

Is urbanization good for the environment? This paper establishes a simple core–periphery model with monocentric cities, which comprises key forces that shape the structure and interrelation of cities to study the impact of the urban evolution on the environment. We focus on global warming and the potential of unfettered market forces to economize on emissions. The model parameters are chosen to match the dichotomy between average “large” and “small” cities in the urban geography of the United States, and the sectoral greenhouse gas emissions recorded for the United States. Based on numerical analyzes we find that a forced switch to a system with equally sized cities reduces total emissions. Second, any city driver which pronounces the asymmetry between the core and the periphery drives up emissions in the total city system, too, and the endogenous adjustment of the urban system accounts for the bulk of the change in emissions. Third, none of the city drivers gives rise to an urban environmental Kuznets curve according to our numerical simulations. Finally, the welfare‐maximizing allocation tends to involve dispersion of cities and the more so the higher is the marginal damage from pollution.  相似文献

The ‘long peace’ of the last twenty-five years has linked various forms of intervention—from development to peacebuilding and humanitarian intervention—with human rights. This ‘interventionary system/order’ model has premised its legitimate authority on expanded versions of human rights, connected to liberal frameworks of democracy, rule of law, and capitalism in order to connect peace more closely with justice. Human rights offer a tactical way forward for those interested in conflict resolution, but this has led to unintended consequences. Unless conceptions of rights are continually expanded as new power structures and inequalities are uncovered and challenged, philosophical and material matters of distributive and historical justice will remain.  相似文献

Abstract: Based on extensive interviews, this study is the first systematic attempt to map the spatio‐temporal evolution of production networks linking urban, state‐owned enterprises and rural, township and village‐owned enterprises in reform‐era China. It identifies two distinct regimes of urban‐to‐rural subcontracting patterns and conventions. The first, which developed and prospered from the mid‐1980s until the mid‐1990s, brought rural workers and the countryside into a relatively extensive relationship with urban capital, and thus represented a partial transition to capitalism. Its violent reconfiguration in the wake of a series of sectoral crises in the late 1990s led to the widespread privatisation of rural enterprises, and the emergence and consolidation of a second regime that simultaneously constituted a significant intensification of relations, the capture of the rural by the urban, and a new stage in this region's transition. This paper argues that these regimes are analogous to the formal and real subsumption of labor to capital, respectively, and that subsumption may be a more useful analytic for understanding the process of capture and transition than primitive accumulation: the latter concept alone, without reference to the dynamics of the social/spatial division of labor, risks missing other ways that exploitive connections can be constructed between places. This paper thus seeks to recast the relationship between these two concepts, and to develop a larger vocabulary in which subsumption, like primitive accumulation, is both spatial and ongoing and internal to capitalist accumulation.  相似文献

In the age of post-Fordist flexible production, a consumer realizes her/his identity in part through the act of consumption. The visual aspect of commodity–consumer negotiation acquires importance, as commodities must be visually differentiated to attract the gaze of a particular consuming group. The act of visual differentiation is achieved through symbolic packaging, which creates a cognitive link between commodity and consumer. I draw from Baudrillard, who states that in postmodern consumption the sign value of products becomes more important than their actual usefulness (use value). Baudrillard, however, overlooks the importance of gender, race and space in this visual mediation. Through an empirical study of the packaging of women's skin and hair products in two different stores catering to two different income groups in Worcester, Massachusetts, I indicate how gendered identities that are created are complex, porous and materially rooted in space. The geographic situatedness of the exercise checks overgeneralizations allowing it to be studied as an object–subject mediation in a particular spatial context.  相似文献
