Indigenous women’s social positionings are complex and dynamic, informed by culture and post-colonial politics; gender and ethnicity intersect with age, socio-economic status, and social hierarchies. This article uses an ethnographic study of Kanak women’s engagements with mining in New Caledonia, to examine three questions. First, how do indigenous women’s dynamic social positionings shape their possibilities for negotiation with and resistance to industry? Secondly, how do women’s possibilities for engagement in turn shape the wider community’s possibilities for negotiation with or resistance to industry? Finally, what is the companies’ role in shaping women’s possibilities for such engagement? I draw on the critical feminist concept of intersectionality, bringing this into conversation with concepts of symbolic and cultural violence and hegemony. Over time, women began to actively negotiate with and resist industrial projects, in line with growing gender equity in New Caledonia, but the mining companies referenced – and thus reinforced – women’s dominated social position as an excuse to sideline their concerns, a type of cultural violence I term ‘retrogradation.’ Thus, this article recognizes indigenous women’s increasing agency in engaging with external actors, such as industrial projects, yet also shows how outsiders can commit retrogradation to further marginalize young, rural, poor community women. I discuss how such marginalization limits options for the larger group. Finally, I point to a way out of oppression, through transformation of hegemonic ideologies.  相似文献

This article addresses the results of a structural strengthening solution for rubble stone masonry walls. The strengthening includes inserting three-dimensional steel ties across the thickness of the walls and a 30-mm layer of air-lime and cement mortar render reinforced with glass fiber mesh (textile-reinforced mortar), on both sides of the wall. The strengthening solution was found to be efficient for rehabilitating ancient rubble stone masonry walls due to the “three-dimensional” confinement, provided by the steel wires, by offsetting the low cohesive capacity of the mortar used in the walls and thus improving the mechanical resistance and delaying the collapse mechanisms. This study is part of an experimental research program carried out in Universidade Nova de Lisboa, to evaluate structural strengthening solutions for ancient rubble stone masonry buildings. To this end, three specimens of rubble stone masonry walls without strengthening (unreinforced masonry) and other three, with the mentioned strengthening solution, were subjected to compression and shear load tests. Building materials were also tested in order to characterize physical, chemical and mechanical properties.  相似文献

The preservation of old downtowns has become a necessity of growing interest. New urban policies have been approved in different countries in order to revive the old city centers and make them economically sustainable. In this global trend, the municipality of Manresa (Barcelona) developed an important urban planning operation in the old district that included the demolition of a group of existing buildings and the construction of a new modern one in close proximity to a group of old residential buildings which are cultural heritage of the city. As a consequence, specific areas of risk were generated which lead to the adoption of precautionary measures to ensure safety. This article presents the preliminary analysis, diagnostics and monitoring carried out on this group of heterogeneous old buildings, as well as the results and precautionary measures taken to ensure their safety. The article also provides a translatable methodology that combines qualitative and quantitative aspects.  相似文献

This article presents a comprehensive overview of the techniques available for the seismic retrofitting of adobe buildings. It analyzes these techniques’ viability from a structural engineering standpoint and evaluates their suitability in the context of historic preservation. Analysis was based on an exhaustive review of studies addressing retrofitting techniques of earthen structures, as well as consultation with field experts. The guiding principles of conservation relating to the structural reinforcement of monuments were taken into account. Traditional techniques that enhance the stability of the building, such as wooden ring beams, wooden ties interconnecting parallel walls, corner keys, and the addition of buttresses were found to be effective solutions since they employ compatible and low-cost materials such as earth and wood. When these techniques prove insufficient, minimally invasive measures such as introducing a plywood diaphragm, horizontal steel rods, a geomesh covered with mud rendering or a strapping system can be appropriate.  相似文献

The article describes the work in progress for analysis of the behavior of the web cracks on Brunelleschi’s Dome of Santa Maria del Fiore. The web cracks in the Dome have always given rise to concern about the stability of the monument. The analyses performed show a slight increase in the size of the main cracks and, at the same time, a relationship with the environmental variables. None of the studies conducted in the past simultaneously involved all the variables detected by the monitoring system. Understanding the relationships among all the endogenous and exogenous variables characterizing the phenomenon under study can help to predict the static evolution of the monument and to automatically detect any atypical behavior, the identification of which would, of course, be of paramount importance for the preservation of the monument, and, more in general, for the preservation of the cultural heritage.  相似文献

Randomized field trials of school voucher policy interventions face major statistical hurdles in the measurement of a voucher effect on student achievement. Selection bias undermines the benefits of randomization when the treatment, a random offer of a voucher, is declined by participants who systematically differ from those who accept. This article argues that the complier average causal effect (CACE) is the parameter of interest in voucher evaluations. As an example, the CACE is estimated using data from a small, one‐year field trial of vouchers in Charlotte, NC. In this estimation, voucher impacts in Charlotte are positive, but appear to be moderated by the probability of compliance. For math achievement, maximum likelihood CACE estimates are smaller and insignificant compared to intention to treat and instrumental variable estimates of mean treatment effects.  相似文献

通过对二里头文化设防聚邑的地理位置和布局以及二里头文化与周邻同期诸考古学文化之间关系的分析,认为二里头文化设防聚邑是夏王朝控辖模式的物化体现,进而将这种控辖模式细分为两类:一是以南、西、北向为代表的开放性控辖模式,二是以东向为代表的封闭性控辖模式。  相似文献

以马斯洛需求层次理论为视角,运用大别山片区微观调研数据,通过理论分析与数理推导,构建结构方程模型,对贫困人口扶贫政策获得感进行综合评价与提升路径研究。结果表明:贫困人口物质需求、安全需求、社交需求、公平需求、能力需求在一定程度上得到满足后均能对其扶贫政策获得感的提升产生正向促进作用,且位于需求层次高低两端的物质需求与能力需求的正向促进作用最强;各维度正向促进作用在不同脱贫状态群体中差异性较大,能力需求对于已脱贫群体获得感提升的影响更为显著;大别山片区整体贫困人口扶贫政策获得感较高,各维度上指数得分差异性较小,但不同地区间存在一定差距。基于研究结果,本文提出一些贫困人口扶贫政策获得感提升路径。  相似文献

ABSTRACT

Since the late twentieth century, the subject of China becoming urban has appeared in the scholarship across the disciplines while spectacular images of China’s cities, and narratives about their developmental achievements, have proliferated in global media. Simultaneously, the parallel “spatial turn” in social thought invigorated geographical approaches to cities and urban change. Yet at this promising meeting ground, between contemporary geographical thought and urban-industrial transformation in China, research has tended to demonstrate a “loss of space” through patterns of dependence on analog circulation of exemplar paradigms that derive from the history of the capitalist city and liberal political economy. What drives this condition and what do we know about its practices and proliferation? This inquiry challenges research design and the politics of theory to consider how routine adoption of capital-centric concepts for research on cities in China arguably reflects the priority of paradigms in the disciplines and their conjunctures with exemplarity in Chinese society and political philosophy. These interstices facilitate application of analog models, and selective adoption of empirical information to suit them, with the paradoxical result of portraying cities in China through multiple capitalist aesthetics including a relatively narrow range of empirics framed by market-based social thought.  相似文献
