社会保障和拉美社会变革

阿根廷《新社会》杂志2010年3—4月号刊登了阿根廷全国科技研究委员会首席研究员、布宜诺斯艾利斯大学教授埃内斯托·阿尔多·伊苏阿尼撰写的题为《社会保障和拉美社会变革》的文章,指出在最近几十年,拉美的社会保障制度出现了三种新现象:一是劳动市场条件恶化,加深了贫困和不平等水平;二是许多国家进行改革后养老保障和医疗保险制度都出现覆盖面下降的问

后苏联空间国家的政治-法律设计--从后苏联空间政权合法化到国家规划探索

苏联解体后,在后苏联空间国家突然拥有国家主权的条件下,新政治精英需要建立一个新的政治-法律空间。对这些国家而言,设计与现实相适应的政治-法律制度、建立稳定的国家体制、制定和实施有效的国家政策的过程过于拖延,前景令人质疑,而且即将面临政治代际更替的全新挑战。后苏联空间非常复杂,但也因此是研究和政治设计的重要地区。20多年的实践表明,不应期待后苏联空间的快速转型。大多数后苏联空间国家未完成国家建设和制度建设,这使形势复杂化,可能导致巨大的变数,包括冲突和诉诸武力。但是,外部环境仍逼迫变革。对于后苏联空间国家而言,变革具有政治理性化和政治制度形式化的目的,包括以法律形式固定政治制度和强制政治设计者更多地在正式法律范围内行事,而达到上述目的的选择包括革命性变革或"自上而下的革命"。     

1999年中国国庆随想

作为新中友协5名老会员之一,我很荣幸能参加中华人民共和国成立50周年的庆祝活动。整个庆典活动令所有人激动不已,让人想起1949年前的许多戏剧性的往事,直到中华人民共和国的建立。 1949年10月1日无疑是20世纪最重要的对未来起到     

后苏联时期的俄罗斯政治领袖

政治领袖是苏联和俄罗斯政治体系中的关键组成部分,在后苏联时代的俄罗斯政治生活中占有特别重要的地位。俄罗斯政治文化一直偏爱强势而有个性的政治领袖,从1917年以来的苏联领袖大多都秉持了这一特点。改革派领导人戈尔巴乔夫由于自己的优柔寡断而丧失了对于改革乃至国家的控制,而与其个人风格和成长经历迥异的叶利钦经历了一系列复杂的政治斗争,最终成为了新生的俄罗斯联邦的领袖。他推动俄罗斯进行了激进的市场化改革,希望使俄罗斯走上以市场经济为特征的"文明之路",但由于复杂的国际国内环境以及政策方面的失误,这一尝试最终以失败而告终。虽然他是俄罗斯第一任民选总统,但叶利钦自相矛盾的执政风格、不稳定的心理状态和诸多生活上的不良习惯都令人诟病,他虽然赢得了竞选连任,但由于身体原因和杜马掣肘,很难有所作为。在经历了复杂的甄选之后,他选择了普京作为自己的接班人,并且帮助普京顺利当选。有克格勃背景的普京是一位具有开拓精神和无比坚韧的性格的领导人。在接任总理之后,很快凭借自己的超群才能,解决了车臣问题,并且有效提高了社会福利,从而迅速提高了自己的威望,以绝对优势当选总统。执政之后,普京很快推动了俄罗斯政治制度新的"转型",他通过除了暴力之外的一切手段强化国家权力,打击"寡头",取消地方选举,限制独立媒体,通过"西罗维基"掌控权力,最终使整个政权集中于自己的手中,形成了被称为"可控民主"或"主权民主"的普京体制。在八年任期结束后,普京拒绝了第三个总统任期,而选择了一项略显复杂的政治安排。将总统职务交给自己的亲信梅德韦杰夫,本人则以总理和统一俄罗斯党主席的身份继续参政,形成了一种特殊的"双头制"政权,直到2012年重返克里姆林宫。随着时代的变迁,俄罗斯正处于发展的十字路口。普京的重新执政对于俄罗斯未来的改革可能将会是一个积极的因素,因为他拥有足够的权力推动改革的进行。虽然面对诸多不确定的挑战,但仍然有成功的机会。

Congenital tetragametic blood chimerism explains a case of questionable paternity

Human chimerism is the presence of ≥ 2 cell populations in one person that contain genetic material from more than one zygote. Chimerism may be either acquired by transfusion or transplantation of donor cells, or congenital arising from embryo fusion or dizygotic twin-twin transfusion. We encountered a 4-year-old boy with developmental hip dysplasia whose preoperative (serologic) blood group was AB, but whose red cell agglutination was atypical ("mixed field") and caused us to study the patient's parents' ABO blood groups. Parental blood groups (AB and O) suggested possible nonparentage. An alternative explanation of the findings was that the child was chimeric or mosaic. Molecular cloning and genotyping of his ABO locus in leukocytes revealed two heterozygous genotypes: A102/O01 and B101/O01. Other loci, each of which possessed three distinct alleles, unambiguously showed transmission of two alleles from either the child's mother (e.g., HLA-A) or two alleles from the child's father (e.g., D8S1179). Findings indicate that the child is a tetragametic chimera.     

The Severe 5%: A Latent Class Analysis of the Externalizing Behavior Spectrum in the United States

Objective

Criminological research consistently demonstrates that approximately 5% of study populations are comprised of pathological offenders who account for a preponderance of antisocial behavior and violent crime. Unfortunately, there have been no nationally representative epidemiological studies characterizing the severe 5% group.

Materials and Methods

Data from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative sample of 43,093 non-institutionalized U.S. residents aged 18 years and older were analyzed using latent class analysis to assess sociodemographic, psychiatric, and behavioral characteristics.

Results

Four-classes of respondents were identified vis-à-vis lifetime externalizing behaviors. A normative class (66.1% of respondents) demonstrated little involvement in antisocial conduct. A low substance use/high antisocial behavior class (20.7% of respondents) and high substance use/moderate antisocial behavior (8.0% of respondents) class evinced diverse externalizing and psychiatric symptoms. Finally, a severe class (5.3% of respondents) was characterized by pathological involvement in more varied and intensive forms of antisocial and externalizing behaviors and extensive psychiatric disturbance.

Conclusions

The current study is the first nationally representative epidemiological study of criminal careers/externalizing behavior spectrum in the United States and validates the existence of the 5% pathological group demonstrated by prior research.     

A novel skull registration based on global and local deformations for craniofacial reconstruction

Craniofacial reconstruction is important in forensic identification. It aims to estimate a facial appearance for human skeletal remains using the relationship between the soft tissue and the underlying bone structure. Various computerized methods have been developed in recent decades. An effective way is to deform a reference skull to the discovered skull, and then apply the same deformation to the skin associated with the reference skull to provide an approximate face for the discovered skull. For this method, the better the two skulls match each other, the more face-like the reconstructed skin surface will be. In this paper, we present a novel skull registration method that can match the two skulls closely, so as to improve the accuracy of the reconstruction. It combines both global and local deformations. A generic thin-plate spline (TPS)-based deformation, which is global, is applied first to roughly align the two skulls based on two groups of manually defined landmarks. Afterwards, the two skulls are largely matched, except some regions, on which some new landmarks are automatically marked. A compact support radial basis functions (CSRBF)-based deformation, which is local, will then be performed on these regions to adjust the initial alignment of the two skulls. Such adjustment can be repeatedly implemented until the two skulls have optimal alignment. In addition, all the skulls and face involved in the registration are represented by their single outer surfaces to facilitate the reconstruction procedure. The experiments demonstrate that our method can create a plausible face even when the reference skull is very different from the discovered skull. As a result, we can make full use of our database to provide multiple estimates for a principle components analysis (PCA) for the final reconstruction.
