共青团组织创立与当代青年的使命

90年前,在中国共产党的正确领导下,诞生了一个全新的以马克思列宁主义为行动指南的中国优秀青年组织——中国共产主义青年团。中国共产主义青年团的诞生,给中国青年带来了深刻、久远的影响,而且也使得中国青年有了自己的组织。当代青年要以共青团组织的历史精神承载起民族复兴的重任。     

Kenneth B. Clark and the problem of power

ABSTRACT

During the early 1960s African American psychologist Kenneth B. Clark, known primarily for his involvement in the 1954 Brown v. Board of Education US Supreme Court desegregation decision, began organizing an ambitious anti-poverty programme called Harlem Youth Opportunities Unlimited, Inc. (HARYOU). Dissatisfied by the lack of progress in school desegregation in New York City and discouraged by the inability of traditional social welfare organizations to address the problems of race and poverty, Clark argued that a new approach had to be developed to mobilize the black poor to gain the political and economic power that would solve their problems. At the same time, he theorized that a new form of racial segregation was beginning to develop in urban areas that foreshadowed increasing social isolation, economic dependence and declining municipal services for many African Americans. He called this new development ‘internal colonialism’ and hoped that HARYOU would be a demonstration project in the Kennedy–Johnson administration's War on Poverty that would address these problems from multiple perspectives. Nonetheless, the plan aroused the political opposition of Harlem Congressman Adam Clayton Powell. The dispute with Powell drove Clark from HARYOU and caused him to re-evaluate his thinking regarding African American leadership. He increasingly viewed the ‘ghetto’ as both a prison and a cocoon that satisfied white and black social, economic, political and psychological needs. By the end of his HARYOU experience, Clark coined the term ‘the new American dilemma’ to describe and theorize about an increasingly isolated and powerless black population in many urban centres. The term also signified his belief that the problem of power was intricately tied up in, while also separate from, the problem of race.     

胸骨形态变化与年龄关系的研究进展

胸骨在发育和退化的过程中,随年龄增长发生着规律性形态改变.国内外学者对胸骨形态变化与年龄的关系做了大量研究,积累了一些宝贵资料,这些成果为研究胸骨三维重建影像的形态变化奠定了基础.三维重组技术的引入,有望引起利用胸骨推断活体年龄方法的突破性发展.本文对相关研究进展进行综述.

Bone age assessment: the applicability of the Greulich-Pyle method in eastern Turkish children

The aim of this study was to investigate whether or not the Greulich-Pyle (GP) method is adequate for Turkish children. A group of 767 individuals (425 girls and 342 boys) between 7 and 17 years were studied. Bone age (BA) from plain radiographs of left hands and wrists by GP standards was estimated. The total mean differences between BA and chronological age (CA) for girls and boys were found to be 0.20 and -0.13 years, respectively. There were significant differences between BA and CA in age groups 7-, 8-, 10-, 11-, 12-, 13-, 15-, and 16-year-olds for girls and 7-, 10-, and 12-year-olds for boys. The results of this study suggest that the mean differences between BA and CA are low enough to be of no practical significance, and thus, for the time being unless any other methods will be proved more useful, this method could be used in all age groups.     

The third molar as an age marker in adolescents: new approach to age evaluation

Adolescence is a relatively short period between childhood and adulthood. It is very difficult to determine adulthood based on biological indicators. The third molar may be considered a potential age marker for the period between the ages of 16–21. Our study evaluated a set of 1700 panoramic radiographs of individuals aged between 5 and 21 years. Results confirmed the statistically significant difference in the course of third molars development. The mean deviation for individuals with one third molar agenesis is ?0.98 years, for individuals with two third molars agenesis ?1.89 years, and with three molars agenesis ?3.28 years. Thus, the extent of the deviation is directly proportional to the number of unformed third molars. The calculation of age according to the mean of stages of all third molars could lead to the underestimation of age. No intergender differences were found. Age determination using third molars could be used for forensic purposes.     

Gang Membership,Gun Carrying,and Employment: Applying Routine Activities Theory to Explain Violent Victimization Among Inner City,Minority Youth Living in Extreme Poverty∗

Conceptual inconsistencies in routine activities theory are illustrated by demonstrating how gang membership, gun carrying, and employment can be categorized as both risk and protective factors in a high‐poverty context. Two waves of longitudinal data from a high‐poverty sample of African American youth were used to examine the determinants of victimization risk. Bivariate analyses indicated that gang membership, gun carrying, and employment status are significant risk factors for violent victimization, but these effects were mediated by measures of lifestyles (e.g., demographic and family factors, deviant lifestyles) included as controls in the full multivariate model. In other words, the strong positive relationship between gang membership and gun carrying found in previous studies may be due to model misspecification and/or the lack of research on high‐poverty samples of inner city youth from the Deep South. Additional logistic regression analyses also indicate that the number of hours employed per week (but not employment status) is a risk factor for violent victimization. Finally, the theoretical implications of these findings for routine activities theory are discussed.     

Local Social Ties and Willingness to Intervene: Textured Views Among Violent Urban Youth of Neighborhood Social Control Dynamics and Situations

Social control in urban neighborhoods has been studied for over a century in America, yet our understanding of the dynamic nature of social relations for exerting informal social control remains limited. The present study uses detailed reports from those most likely to be the target of local control efforts—violent youth in extremely disadvantaged urban locations—to re‐examine two features of this work: variations across different hypothetical scenarios widely used in this research, and connections between local ties and intervention type and likelihood in actual events. In‐depth qualitative interviews from 159 violent males aged 16–24 from two distressed New York City neighborhoods identify ways in which responses to commonly used scenarios of informal social control are age‐ and space‐graded. Reports on the transactional nature of social control in violent events show how local ties may undermine, rather than support, social control processes. It would appear that we need to consider more carefully general suggestions about local ties encouraging more informal social control, move to a more textured, multithreaded view of these connections, and incorporate age‐ and space‐graded dynamics into future studies of social control.     

论欧盟公共采购法采购主体的界定标准及其对我国的借鉴意义

欧盟公共采购法包括三类主体———公共部门、经营四个指定公用事业行业的公共企业和在政府授予的特殊或排他性权利基础上开展经营的私有企业。其中将公共部门纳入政府采购是由于委托—代理关系的存在,而将企业纳入政府采购是为了防止政府对企业的采购过程施加影响。相比之下我国政府采购法规定的采购主体仅限于公共部门的范畴,这是由我国目前的社会经济发展需要决定的。政府采购法的采购主体制度不是一成不变的,应随着社会经济发展需要的变化而发展变迁,我国国有企业改革完成后,也应将国有企业按照不同性质进行分类,一部分由竞争法调整,一部分纳入政府采购法的调整范围。     

儒家义利观及其当代价值

中国儒家关于义利之辨的话题已探讨了多年,在不同的时代,人们赋予它不同的内涵。随着我国市场经济的逐步深入发展,人们的义利观也出现了很大的变化。本着对儒家传统义利思想批判和继承的态度,结合当今的具体国情,本文试分析市场经济下义利的新关系及正确对待的措施。
