The Ecology of Command: U.S. Pacific Command and the Environment of the Pacific Rim

Abstract

Environmental ethicists speak fervently about the impact of human activity on the sustainability and survivability of Earth's community. But often these discussions fail to acknowledge one human activity more powerful and with the potential for greater destruction than any other— the United States military and its "empire of bases" encircling the globe. Military operations, both peacetime missions and contingency operations, and military installations stamp a large footprint on the earth's environment. From the atmospheric nuclear tests in the Bikini Atoll to the removal of the coral reef at Diego Garcia, the environment of the Pacific Rim has been shaped by the demands of U.S. national security. This paper examines the environmental footprint of U.S. Pacific Command. Secondly, it suggests that the exigencies of U.S. military presence need to be included in discussions of environmental ethics.     

论地缘战略的主体间性——兼论中国地缘战略抉择

主体间性一词是20世纪西方哲学凸显出来的一个重要概念,对这一问题的研究有助于解决本体论、认识论和伦理学等多方面的问题。简单来说,主体间性就是主体之间的交互作用。主体间性具有物质性、实践性、历史性和社会性,其存在于集体主体之中,可以通过"教化"获得。据此,本文通过对四个经典地缘政治理论,即国家有机体论、海权论、陆权论和边缘地带论的历史分析,挖掘了隐含在其中的主体间性。并以美国对苏联和中国实施的地缘战略围堵为例,通过分析同一地缘战略所导致的截然不同结果,表明了地缘战略的构建、制定和实施都必须遵循主体间性。最后根据主体间性提出中国未来地缘战略抉择。     

中国大城市保障房社区的邻里效应研究——以广州市保障房周边社区为例

随着我国保障房建设速度的加快,保障房社区将对已有的城市社会空间结构带来深刻影响,其社会效应亟需深入探讨。本文以邻里效应为切入点,基于社区调研数据,采用因子分析、回归分析和质性研究方法,研究广州市保障房社区对周边社区的影响,以及这种影响的形成机制。研究发现,保障房社区并没有为周边社区带来负面的影响,也不存在"贫困同质化"的现象。然而,保障房居民与周边社区居民缺乏人际交往,其社会融合度也比较低。结果表明,提升保障房社区的社会认同度,消除不同社区居民相互间的隔阂,对构建和谐社区具有重要的意义。     

建国初期湖北没收官僚资本的措施及成效

解放前,湖北官僚资本企业遍及电力、化工、纺织、机械、炼油、印刷、军工、公用等工业各行业,主宰湖北经济命脉。从湖北解放至1952年,湖北军管会采取种种举措,彻底没收了在鄂的全部官僚资本,并建立了社会主义国家银行、国营工商业等国营经济,奠定了湖北的社会主义经济基础。

Scales of regional income disparities in the USA, 1955 2003

This article examines multiple dimensions of regional per capitaincome disparities in the USA between 1955 and 2003 with a particularfocus on scalar effects. It combines various exploratory analyticaltools of spatial disparities, including inequality indices,mobility indices, kernel density estimation, spatial autocorrelationstatistics and scale variances, to analyse regional averageper capita income distributions at multiple spatial scales,ranging from counties to multi-state regions. The analysis revealspreviously unrecognised systematic patterns of cross-scalardynamics, whereby spatial income disparities are increasinglymore pronounced at smaller scales in the last few decades.     

War and city size: The asymmetric effects of the Spanish Civil War

Populations are affected by shocks of different kinds, and wars, a priori, may be among the most prominent. This article studies the effect of the Spanish Civil War (1936–1939) shock on the distribution of population, especially on cities. One of the main contributions of this study is that it underlines the importance of distinguishing between winning and losing sides, an aspect which until now has been largely overlooked. While previous research on war shocks has also tended to be concerned with inter-state wars, this paper concentrates on a civil war. We take advantage of a new, long-term, annual data set. Our results show that, overall, the Spanish Civil War did not have a significant effect on city growth. However, we also find a significant and negative effect in the growth of cities that aligned themselves with the losing side. These results are robust to heterogeneity in the effect of the war shock, measured as war severity and duration. Although short lived, the temporary effect on growth results in a permanent effect on the size of cities on the losing side.     

Introducing urban vitality as a determinant of children's healthy mobility habits: a focus on activity engagement and physical activity

In this study we introduce urban vitality as a determining factor for both physical activity (PA) and activity engagement in children living in Barcelona's Metropolitan Region. We compare the physical outcomes of children living in vital and non-vital areas using mobility data taken from a travel survey. Chi-square, and association tests were used to compare the health outcomes of children living in vital and non-vital areas. Specifically, we measured for activity engagement, walking for transport, minutes of PA and adequacy to World Health Organization PA recommendations. Results are stratified by age and gender and reveal how living in a vital area can produce up to 54 minutes more of PA per week, with a difference of nearly 20% in the number of outdoor activities undertaken. Neighbourhood vitality promotes healthier mobility habits, as children living in buzzing areas tend to engage in more activities and spend more minutes walking for transport.     

国外博彩旅游研究:进展、脉络和展望

近几十年来,国际旅游学者针对博彩旅游开展研究,研究范围涉及消费者行为、影响和政策等主题,得到许多有益的发现;然而,国内研究对该领域的关注则较少.本文在梳理国外博彩旅游文献的基础上,按照主题对文献内容进行分析总结,研究发现:(1) 博彩行为和博彩影响研究最受重视,研究方法以定量为主,研究理论涉及社会学、管理学和经济学等多学科;(2) 博彩行为研究中,不同类型博彩者行为研究和中国博彩者行为研究备受关注;(3) 博彩影响研究中,关键变量的识别、关键模型的构建对于未来进一步深化研究有重要作用.     

Structural Integrity of Stone Blocks From Charles Bridge in Prague

The Charles Bridge is the oldest, still-standing gothic bridge that crosses the Vltava River in Prague and up to now has belonged among the most sought-after historical monuments in the Czech Republic. The bridge has been repeatedly damaged due to floods and has been repaired several times. In the reconstructions, damaged sandstone blocks were substituted in facing. This experimental study focused on nonlinear ultrasonic spectroscopy for testing stone blocks that were extracted from the historical bridge structure. The objective of these experiments was verifying whether the methods can be applied to evaluating the internal structure of blocks, which are built-in in the structure in situ. Intact-structure blocks, blocks that had been repaired in the past, and damaged-structure blocks were measured. Two methods of nonlinear ultrasonic spectroscopy were applied—the method with single harmonic ultrasonic signal and with two harmonic ultrasonic signals. Measurement results of both applied methods proved resulting parameters correlation with block structure integrity quality.
