危机幕后的东亚地区秩序分析

本文认为,东亚当前出现"大战不犯,小乱不断"状况的根源在于新旧嬗变中的地区秩序远未就域内各国的政治安排形成制度化设计,在于东亚地区秩序的"有气无力"。历史上,东亚地区秩序曾经历了天朝礼治秩序、条约秩序和冷战下"自主"秩序三种形态。依据历史脉络的梳理,本文认为有美国、中国、日本等七个要素影响着东亚地区秩序。为明确这些要素的特征及相互作用,本文提出了反映国家和国家关系总体形态的"锥体"模型。美国是影响东亚地区秩序的决定性变量,利用"锥体"模型,本文认为,美国现实主义的热情与贪婪,地缘战略的坚持与冷静,相互依赖的推动与困惑等特征共同勾画着东亚战略。中国的复兴是影响东亚地区秩序的突出变量,其显著特征在于整体性的成长。日本"正常化"是影响东亚地区秩序的另一主要变量,其特征在于日本自身的"二重性"。朝鲜半岛、台湾、东南亚由于其关键性和不稳定性而成为东亚地区秩序的缝合口。此外,俄罗斯要素也不可或缺。在美国要素与中国、日本等要素的复杂互动中,中美关系是东亚地区秩序的主轴,作为其中一方的中国,如何把握自身不断增长的力量至关重要。     

Do vehicle recalls reduce the number of accidents? The case of the U.S. car market

The number of automobile recalls in the U.S. has increased sharply in the last two decades, and the numbers of units involved are often counted in the millions. In 2010 alone, over 20 million vehicles were recalled in the United States, and the massive recalls of full model lines by Toyota have brought this issue to the front pages around the country and the world. However, there is no quantitative evidence of the effect of recalls on safety. Without that evidence, the government and insurance companies have been reluctant to request and use more detailed recall information to increase correction rates, and regulators have not studied the possible link between the growing number of recalls and the risk of life for consumers. In this paper we empirically quantify the effect of vehicle recalls on safety using repeated cross‐sections on accidents of individual drivers and aggregate vehicle recall data to construct synthetic panel data on individual drivers of a particular vehicle model. We estimate the effect of recalls on the number of accidents and find that a 10 percent increase in the recall rate of a particular model reduces the accidents of that model by between 0.78 percent and 1.6 percent when using the full sample of accidents in our data. We also find that recalls classified as “hazardous” are more effective in reducing accidents, and the recall effect is especially strong when we restrict attention to accidents that lead to personal injuries and only include vehicles more likely to be at fault for the accident, but much less so for accidents that only lead to property damage. We also find that vehicle models with recalls with higher correction rates have on average fewer accidents in the years following a recall, which indicates the importance of the role of drivers' behavior regarding recalls on safety. Our findings suggest that policymakers should consider, for example, policies to allow insurance companies to take into account recall correction behavior when pricing auto insurance, which could be made possible through regulatory changes by the U.S. government, and should revisit the complex trade‐offs between pre‐ and post‐market regulation in this important industry. © 2011 by the Association for Public Policy Analysis and Management.     

Distribution of the minutiae in the fingerprints of a sample of the Spanish population

One of the fundamental aspects of the process of identification through fingerprints is the comparison of the minutiae between the fingermark obtained at the scene of the crime and the suspect's corresponding finger. There is no scientific basis in this process that allows the use of numerical standards, such as those kept in different countries, to obtain the identification. The recent mistakes made in the field of dactyloscopy, together with the growing rigor and scrutiny that forensic evidence undergoes in the legislative and scientific areas, have resulted in the need to reconsider some of the basic principles that support this discipline. A probabilistic estimation of the evidential value is especially necessary; therefore, it is indispensable to know and quantify the variability of the features used in the identification process. The sample studied for this research was obtained from 100 Caucasian men and 100 Caucasian women from the Spanish population, which amounts to a total of 2000 fingerprints. The different types of minutiae were located, identified, and quantified visually on the fingerprint, in four sectors, and inside and outside of a circle, whose radius cut, perpendicularly, fifteen ridges starting from the center cut of the axes that defined the sectors. According to the results obtained in this study, through dactyloscopic identification, the weight of the evidence of a minutia, such as the ridge endings, with frequencies between 55% and 65%, according to the area and gender evaluated, cannot be the same as that of a bifurcation or convergence, with frequencies of 13-18% or those of other minutiae that show frequencies lower than 3%. The significant differences found in the topological distribution of the endings, bifurcations, and convergences show the need to take into account, for its demonstrational value, the finger area in which they are evaluated. The significant association observed between the types of minutiae and the different fingers revealed a greater frequency of endings on the thumb and index fingers, and bifurcations and convergences on the middle, ring, and little fingers.     

联合国开创了两个危险先例

今年以来,西方国家对利比亚的连日空袭和西方驻科特迪瓦维和部队直接参与科国内的战斗,开创了联合国在处理主权国家内部事务问题两个危险的先例。这为霸权主义和强权政治欺压发展中国家尤其是弱小国家开了新的绿灯,将对国际安全与和平和联合国成员国的主权带来严重威胁和后果。为了制止和遏制这种严重违反《联合国宪章》和安理会决议的行径,联合国和国际社会应立即行动起来,一是对《宪章》的有关条款作出明确的定义;二是建立具有法律效力的独立监督机制,审议和监督安理会决议的执行情况;三是安理会立即召开会议审议1973号决议执行情况,提出政治解决利比亚问题的方案。
