不同铺装材料的颗粒物干沉积效果研究

以水泥板为对照项,根据干沉积量,研究了不同气象条件下水面、碎石、陶粒、卵石和塑胶垫等材料的固尘效果。结果表明,碎石等固体铺装材料的干沉积量与材料表面的粗糙度呈正相关性,与风速呈负相关性;碎石固尘效果好、价格低廉,是北方缺水城市优先选择的铺装材料。     

关于国内客运航班延误的几个法律问题--兼及相关法律的完善

在航空运输中,由于多种原因,航班延误难以避免,因航班延误引起的纠纷时有发生.现行的民航法及相关法规对于航班延误的定义、承担延误的责任原因、承担责任的方式、延误赔偿限额等问题或者没有规定,或者规定太原则、笼统、不统一,缺乏可操作性.时至今日,关于航班延误的诸多问题仍然不能"依法解决".有关部门应当尽快制定并完善相关法律法规,使航班延误的处理工作步入法制化的轨道,依法解决航班延误的有关问题.     

Searching for Kin Amidst Tragedy—Disaster Victim Identification Operations for US Bangla Flight 211

The nature of air disasters includes factors that exacerbate challenges in the identification process. Of the 49 deceased in the US Bangla air crash in Kathmandu, Nepal, four were intact, 11 presented with burn injuries, another 11 presented with partial charring, and 23 were completely charred. Personal belongings were useful in the identification phases for all types of victims. Fingerprints were obtainable and useful in intact victims and victims with less severe burn injuries; medical and surgical information was useful in bodies with burn injuries; finally, dental findings were useful in cases of extensive charring. Other useful methods in the process included marks of identification, physical features, and exclusion. In certain resource‐limited settings, especially in closed population disasters, where scientific identification (DNA, dental records, etc.) is not currently available, personal belongings, clothing, and physical findings analyzed by an identification team using a structured organization may be cautiously used as the primary means of identification.     

（后）现代性与移动性：生态环境所面临的挤压——兼论旅游人类学视野中的“旅游文化”

"全球化"使得"现代人类"叙事更加充分,政治经济领域,社会文化的各个方面也出现空前的"移动-流动"景象,越来越多的人更加担心"文化的全球化"给人类所带来的隐忧.如果生物的多元性、文化的多元性、地方特色的多元性等得不到很好的保护和保存,那么,"可持续发展"的核心价值和关键意义便无以兑现.     

论航空运输中对旅客的损害赔偿责任

航空旅客运输有国际国内之分,在法律适用上有所差异;国际航空运输中主要适用华沙体系和1999年《蒙特利尔公约》,国内航空运输则适用各国国内法的规定。从国际航空公约和我国航空法对旅客损害赔偿责任体系的比较看,二者对旅客损害赔偿责任期间、损害构成、赔偿主体等规定模糊,我国航空法对旅客损害赔偿的归责原则规定的比较单一,赔偿标准较低。我国应当结合国际航空条约中的有益规定和国内相关法律中的规定对航空法进行修订,这是健全和完善我国航空法体系的必由之路。     

The problem with English(es) and linguistic (in)justice. Addressing the limits of liberal egalitarian accounts of language

Van Parijs’s Linguistic Justice for Europe and the World furthers a nascent examination of multilingualism within political philosophy, drawing on continental European contexts where multilingualism is the norm. Van Parijs argues, in effect for linguistic cosmopolitanism via English as the current world language, and this seems ostensibly to be a considerable improvement on ‘the untrammeled public monolingualism’ of Anglo-American political theory. However, Van Parijs’s account is flawed in four key respects. First, there is the fundamental problem of his reductionist account of language – by which language is viewed only in terms of its communicative uses and reach and not in relation to its symbolic and identity functions. Second is his simplistic advocacy of English as a global lingua franca, which ignores issues of power and inequality, along with related delimited access to high-status English language varieties. Third are the inherent limitations associated with his advocacy of linguistic territoriality, which recognizes state-sanctioned languages but little else, thus failing to mitigate existing linguistic hierarchies. Finally, the wider argument for English as a global lingua franca is inevitably underpinned by a monolithic/hegemonic view of English itself. This monolithic conception of English stands in contradistinction, not only to the actual plethora of Englishes in the world today, but also, more importantly, to their widely varying status and use in furthering cross-communication and related notions of social and economic mobility. The latter thus fatally undermines Van Parijs’s central argument linking social and economic mobility ineluctably to access to English.     

HOPE VI–a viable strategy for improving neighborhood conditions and resident self-sufficiency? The case of Maverick Gardens in Boston

This article considers whether the HOPE VI program has achieved two of its key goals: improving neighborhood conditions and increasing resident self-sufficiency. Findings from the Maverick Gardens HOPE VI program in Boston, Massachusetts are presented and discussed in the context of other research on HOPE VI and other relocation initiatives.

Evidence from the Boston site affirms that the combination of relocation and redevelopment can lead to dramatic improvements in neighborhood quality for many – but not all – residents. Self-sufficiency outcomes, on the other hand, were not achieved: employment did not change, job networks were not expanded to new neighbors, and some residents experienced a decline in economic stability as a result of the program. Why HOPE VI has failed to improve neighborhood conditions for all residents and why it has failed to impact resident self-sufficiency is discussed, and how program goals and strategies might be adjusted to make it more effective is considered.     

You gotta move: advancing the debate on the record of dispersal

This paper summarizes the social science research on the record of housing dispersal programs since 1995. The research shows a consistently disappointing record of benefits to low-income households. Households moved out of high-poverty neighborhoods, voluntarily and involuntarily, show few or no beneficial effects in terms of economic self-sufficiency, health benefits, or social integration. The benefits of dispersal are confined to feelings of greater safety and satisfaction with neighborhood environmental conditions. We offer a framework for understanding the disappointing record of dispersal, highlighting its translation from social science diagnosis to policy, problems in the policy's implementation, its underlying theory of poverty, and the political context within which dispersal has been applied.     

A different lens: administrative perspectives on portability in Illinois' Housing Choice Voucher Program

Over the last decade, the Housing Choice Voucher Program has grown to become the USA's primary strategy for providing safe, decent, and affordable housing. Annually serving more than 2 million low-income households, the program is designed to help low-income households afford private market rental housing. The program also allows for the “portability” of vouchers nationally between housing authority jurisdictions. Both features aim to mitigate the effects of concentrated poverty. Research on the Moving to Opportunity Program and the Gautreaux consent decree have produced data confirming that residential mobility can at times lead to positive opportunities for assisted households. This past research has been conducted on specific programs occurring outside of the general Housing Choice Voucher Program framework and has focused on household-level outcomes, paying little attention to the ways in which program administration may affect outcomes for voucher households. This article aims to understand voucher portability from the perspective of housing authority executive directors and program administrators, in order to better understand how program administration impacts the types of household outcomes observed in prior research. The results reveal that housing authority administrative practices and inter-housing authority relationships play a significant role in shaping the types of outcomes realized by porting voucher households. These findings suggest several changes to program administrative design and policy that may improve support for voucher households as they make portability moves.
