Abstract: This paper traces how Los Angeles peace activists tried to make visible the grave domestic effects of Cold War militarization. Women Strike for Peace went beyond a focus on the productive relations between the state, military and industry captured by the term “military–industrial complex” to analyze how reproductive spaces were part of this complex. In opposing war, they challenged what I am calling militarized domesticities: how war‐making shapes the ‘home front’ and home as the spaces national security states claim to protect. I build on feminist antiracist intersectionality theories to situate the military–industrial complex per se within broader processes of the militarization of society and daily life. The questions become how do gendered processes of militarization—that work in conjunction with relations of white privilege—produce and connect differently situated “private” spaces or home places? How might strategies for dismantling the military–industrial complex emerge from the contradictions of these processes?  相似文献

Bruce Trigger's and Adam Smith's comparative studies of state-level societies provide new theoretical approaches and are important components in a resurgence of explicit comparative analysis of early states by archaeologists. Trigger presents a massive systematic comparison of seven ancient states on an unusually large number of themes, whereas Smith carries out more intensive comparisons of a smaller sample on more limited themes. These well-written works make significant contributions to a number of areas, including empirical analysis, theory, and comparative methods.  相似文献

Four recent books deal with the origins of early writing systems, the implications of texts and artifacts on the development of cognitive process and social practice, and the importance of textual artifacts for cultural cohesion and attendant issues of power and identity. This review draws out the interrelation of writing and speech, the conceptualization of literacy as singular and autonomous or multiple and ideological, and where and how to place forms of visual communication within the paradigm of “literacy.”  相似文献

The new interest in cultural landscapes is forcing a reappraisal of concepts of countryside heritage. First the traditional split between cultural and natural values is challenged. Second, modern landscape studies emphasise the subjectivity of landscape assessment, and this is subverting the former tendency to aspire to objectivity in evaluation. The acceptance of ‘associative’ value in landscape is an indicator of this. Modern landscape studies also emphasise the interrelationships between processes and aspects of value, and this is encouraging specialists to communicate across disciplinary frontiers. The desire by ecologists in the mid‐1980s to have cultural landscapes inscribed on the World Heritage list caused a re‐assessment of the World Heritage Criteria, and an initiative by ICOMOS brought this process to a conclusion in 1992. However the reappraisal of concepts of countryside value imply that there are many other philosophical and practical matters still to be resolved.  相似文献

The recent drive for use of performance based methodologies in design and assessment of structures in seismic areas has significantly increased the demand for the development of reliable nonlinear inelastic static pushover analysis tools. As a result, the recent years have witnessed the introduction of the so-called adaptive pushover methods, which, unlike their conventional pushover counterparts, feature the ability to account for the effect that higher modes of vibration and progressive stiffness degradation might have on the distribution of seismic storey forces. In this paper, the accuracy of these force-based adaptive pushover methods in predicting the horizontal capacity of reinforced concrete buildings is explored, through comparison with results from a large number of nonlinear time-history dynamic analyses. It is concluded that, despite its apparent conceptual superiority, current force-based adaptive pushover features a relatively minor advantage over its traditional non-adaptive equivalent, particularly in what concerns the estimation of deformation patterns of buildings, which are poorly predicted by both types of analysis.  相似文献

基于SEA的AGA-SVR节假日客流量预测方法研究   总被引:2,自引:0,他引:2  
节假日旅游客流量由于游客在短期内大量集中于同一地点、不同节假日休假时间长短、所处季节等不同,呈现复杂非线性特征和明显季节性特点.本文提出一种基于季节指数调整(Seasonal Exponential Adjustment,SEA)的自适应遗传算法(Adaptive Genetic Algorithm,AGA)-支持向量回归 (Support Vector Regression,SVR)预测模型,即基于SEA的AGA-SVR模型,并用国内著名5A级风景区黄山2008~2012年节假日客流量数据对模型进行验证.研究结果表明,基于SEA的AGA-SVR预测模型能够准确处理节假日旅游客流量预测中的非线性和季节性问题,较AGA-SVR和GA-SVR等方法具有更高的预测精度,在旅游预测领域应用前景广阔.  相似文献

Earlier views saw West Africa as culturally stagnant through much of the Holocene until stimulus or intervention from north of the Sahara transformed Iron Age societies. Evidence accumulating over the past 15 years suggests that stone-using societies from 10,000 to 3000 B.P. were far more diverse than previously thought. Against an increasingly detailed record of Holocene climate change, the complexity of local adaptation and change is becoming better understood. Although a strong case currently exists for the introduction of copper and iron to West Africa from the north in the mid-first millennium B.C., the subsequent development of metallurgy was strongly innovative in different parts of the subcontinent. Soon after the advent of metals, a dramatic increase in archaeological evidence for social stratification and hierarchical political structures indicates the emergence of societies markedly more complex than anything currently documented in the Late Stone Age. The best-documented examples come from the Middle Niger region and the Nigerian forest. In these areas, earlier diffusionist models in which complexity originated outside West Africa have yielded to evidence that indigenous processes were instrumental in this transformation. Trade, ideology, climate shifts, and indirect influences from North Africa, including the introduction of the domesticated horse to the Sahelian grasslands, are identified as factors essential to an understanding of these processes.  相似文献
