转型期我国阶级阶层关系调研报告

伴随着改革开放,我国社会成员的分化成为不争之实。目前,考量社会成员之间的分化主要基于经济利益分化。虽然分化过程显失公平,但社会成员在政治认同和价值认同方面却保持了较高的一致性。在阶级阶层关系中,干群关系、新老阶层关系值得关注。因此,需要倚重以党和政府为主导形成的合力,着力解决收入分配等问题,破解干群矛盾,促进阶级阶层关系的和谐,逐步形成与经济社会现代化相辅相成的现代化的社会结构。     

Infant death due to air embolism from peripheral venous infusion

An otherwise healthy male infant was brought to the hospital because the mother suspected superficial infection at the operative site 5 days after an inguinal hernia repair. He was admitted to the pediatric unit overnight to be evaluated by his surgeon the next morning. When a venous infusion of maintenance fluids was started, the patient immediately went into cardio-respiratory arrest and was pronounced dead after resuscitation efforts failed. Subsequently, air collections were found in both venous and arterial circulations, including the splenoportal system. Detailed review of the clinical presentation and course, laboratory results, radiological, and pathological findings, along with a review of pertinent literature provides an explanation for the death by air embolism. Apparent inconsistent findings both radiographically and at autopsy are resolved. The mechanism of distribution of air to both systemic and splenoportal circulation is discussed. We believe this to be only the eighth case reported in English-language literature of infantile death from peripheral venous infusion. In all age groups, we find only six other cases in the English-language literature of gas found concomitantly in both the systemic and portal venous systems.     

试论国际航空承运人对旅客的赔偿制度及我国立法对策

1929年以来,世界各国在民用航空领域相继达成了一系列国际条约或协定,其中以1929年华沙公约为主轴,因此,这一系列条约所形成的国际航空承运人赔偿制度,被国际民航界称之为“华沙体系”。2003年正式生效的1999年蒙特利尔公约对“华沙体系”进行了修改,形成了新的国际承运人责任赔偿制度,我国应当与蒙特利尔公约接轨,进一步完善有关的国内立法。     

Rapid separation and characterization of cocaine and cocaine cutting agents by differential mobility spectrometry-mass spectrometry

Forensic drug laboratories are inundated with cases requiring time-consuming GC- or LC-based chromatographic separations of submitted samples. High-throughput analytical methods would be of great practical utility within forensic drug analysis. Recently developed ion-mobility-based separation methods combined with mass spectrometry can often be used without chromatography, suppress chemical interferents of similar mass, and operate in seconds. We have evaluated differential mobility spectrometry-mass spectrometry (DMS-MS) for performance on adulterated cocaine mixtures. The DMS interface is only a few centimeters in length, operates in seconds, and can be adapted to any MS system using atmospheric pressure ionization. Drug cutting agents, typical targets such as cocaine, and drug metabolites are rapidly separated by the DMS ion prefilter. Tests demonstrated characterization of complex mixtures, such as isolation of levamisole, an adulterant with alarming side effects, from a 13-component mixture. DMS-MS holds great potential for the analysis of drug samples submitted for forensic analysis.     

对国家《室内空气质量标准》的几点质疑

新装修房屋室内空气污染问题越来越受到人们关注。2003年颁布实施的GB/T 18883—2002《室内空气质量标准》虽然在很大程度上限制了装修所引起的室内空气污染,但在实施过程中发现,《室内空气质量标准》对化学性污染物标准检测方法有些矛盾的地方,影响了测量精度和准确性。笔者提出了质疑和改进的建议。     

Swiss Air Traffic Policy: Noise between Berne and Berlin

This article looks at the negotiations between Switzerland and Germany on air traffic regulation with the help of negotiation analysis tools. A number of factors pre‐eminent in the literature on negotiation processes and outcomes are presented and critically assessed. In particular arguments of “power”, which are often insufficiently explored in analysing interstate cooperation, are brought back into the picture. The article argues that structural power best explains the negotiation results while domestic politics and information asymmetries both account for non‐ratification of the treaty. Institutionalist arguments on the constraining effects of international norms and institutions as well as explanations focusing on negotiation skills are of minor importance. Moreover, the nature of the Swiss intra‐governmental setting at the federal level did not encourage the Swiss negotiators to exploit all means during the different stages of the bargaining process. The article concludes by illuminating a number of policy observations in the broader context of Swiss foreign relations and indicating avenues for further research.     

民工潮与城乡收入差距

农村劳动者到城镇打工,他们将自己获得的收入寄回家乡,提高了当地农村居民的家庭收入,但这并没有缩小城乡收入差距,相反我国城乡收入分配差距呈逐渐拉大之势。这里有复杂的原因。从目前来看,我国农村劳动力流向城镇对缩小城乡收入差距没有多大帮助,要有效缩小我国城乡收入差距还应结合消除不合理的行业进入壁垒,发展农村经济等措施。

Looking for the state and finding god: conceptions of security among low-income Cairenes

This article analyses how low-income individuals in Cairo, Egypt interpret the aspects of security and insecurity that affect their daily lives. Particular attention is paid to crime and failing transportation infrastructure during Mohammed Morsi’s presidency, 2012–2013. Primarily, I show how religion is both a tool and coping mechanism to help combat chronic periods of insecurity. Participants invoke religion to force officials to perform their duties and to perform them honestly. Secondly, religion is called upon as a final form of mental and spiritual relief against injustice and the trials of daily urban life. This paper seeks to make an intervention into security studies by showing how Egyptians defend themselves through personal and communal understandings of religion in distinction to security practices enacted by the state and other national and international organizations.     

Moving to Location Affordability? Housing Choice Vouchers and Residential Relocation in the Portland,Oregon, Region

Abstract

Location affordability measures a household’s combined cost of housing and transportation. Low-income households have the most to gain from housing with lower transportation costs. This research analyzes whether Housing Choice Voucher Program households—participants in a program designed to provide low-income households with a greater degree of housing choice—are able to choose housing that lowers their transportation costs in a metropolitan region with a compact, vital urban core. A mixed-methods approach is used to investigate the differences in location affordability and efficiency among 2,026 voucher recipients who moved within the Portland, Oregon, region during 2012–2013. Location mattered to movers, but in some unexpected ways. Urban movers relocated to less location efficient areas, whereas suburban movers’ location efficiency remained stable. In tight housing markets, voucher holders may be edged out of location-efficient neighborhoods and thus incur increased transportation costs.
