相对资源视角下城市青年夫妻的除夕安排

利用中国人民大学人口与发展研究中心2009年的“中国城市青年状况调查”数据,对城市青年夫妻陪伴哪方父母过除夕及其影响因素进行研究分析发现：在除夕夜陪伴丈夫的父母是当前城市青年夫妻的主流选择,夫妻的独生子女属性与相对资源拥有情况会影响除夕安排,当只有妻子是独生子女时,青年夫妻并不会更倾向于陪伴妻子的父母,但更有可能单独度过除夕或轮流陪伴两方父母;而妻子拥有房产或收入更高时才会大大提高陪伴妻子父母的可能性。     

浅析活体损伤法医学鉴定及应注意的问题

随着我国法制化建设的不断加强,司法实践已对活体损伤法医学鉴定提出了更高的要求。要使活体损伤的法医学鉴定真正实现依法、客观、公正、科学,就必须要正确理解和运用法律规范,严格活体损伤鉴定程序,遵循活体损伤鉴定基本原则和依据,了解相关因素及其注意事项,熟练掌握检验鉴定的基本方法技能。以严谨求实的态度和高度负责的精神,综合分析、深入研判活体损伤鉴定相关问题,才能确保活体损伤鉴定质量,适应新形势的需要。     

论坚持和培养艰苦奋斗的精神品格

艰苦奋斗,是一种精神品格,不仅仅是个人的修养,而且是民族的灵魂,是国家发展的动力之源。对于已经从革命党转变为执政党的中国共产党来说,艰苦奋斗是提高执政能力的基础。艰苦奋斗的精神能不能在新的历史时期继续发扬光大,关系到执政党的生死存亡。     

Gender and Juvenile Drug Abuse: A General Strain Theory Perspective

This study is a partial test of Robert Agnew's (2006 Agnew , Robert. 2006 . “Pressured Into Crime: General Strain Theory.” Pp. 201 – 209 in Criminological Theory: Past to Present. , 3rd ed. , edited by F. T. Cullen and R. Agnew . Oxford , England : Oxford University Press . [Google Scholar]) general strain theory. The sample consists of 39,879 juveniles between the ages of 10 and 17 from a metropolitan area in Texas with more than 5 million people. Logistic regression is used to determine the effect of living situation on drug offenders, drug recidivists, and juvenile court case outcome when race, abuse, sex, and mental health problems are controlled. Gender-specific analysis is used to test L. Broidy and R. Agnew's (1997 Agnew , Robert and Timothy Brezina . 1997 . “Relational Problems With Peers, Gender, and Delinquency.” Youth & Society 84 – 111 .[Crossref], [Web of Science ®] , [Google Scholar]) hypothesis that girls and boys react differently to strain. Results show partial support for the influence of a strained living situation on drug offenders, drug recidivists, and case outcome. Support is found for the hypothesis that boys' and girls' experiences with strain differ.     

Incarcerated Parents and Health: Investigating Role Inoccupancy Strains by Gender

This article elaborates research on parenthood, gender, and health by considering the context of incarceration using the stress process paradigm. The chronic strain of non-participation in a desired role, or “role inoccupancy,” in the form of non-resident parenthood on arrest is associated with psychological distress at time of lockup among women but not men, indicating a gendered strain. However, for both incarcerated men and women, anticipated resident parent role inoccupancy upon release (or expectations not to live with their minor children) is generically associated with current subjective mental health problems net of distress prior to lockup. Role inoccupancy strains are further associated with subjective physical health problems among women but not men, indicating more pervasive associations among the former.     

Wage Differentials in Brazil: Theory and Evidence

The investigation of wage determination and wage differentials in developing countries has concentrated on the effects of human capital and different sources of segmentation associated with institutional arrangements and structural characteristics on earnings. In this article, we use micro-data for Brazil for the 1980s and 1990s to test several competitive theories, and models with segmentation explained by efficiency wages. We find that unmeasured abilities and efficiency wage models seem to play a role in wage determination, while compensating differentials and transitory difference theories were found to be irrelevant to wages formation.

基于X线的活体骨骼年龄评定方法及其他技术

国内外通常利用X线片观察骨骼继发性骨化中心的出现和骨骺闭合程度的影像学特征来推断年龄。其中较常用的方法有计数法、计测法、图谱法、评分法及计算机辅助评定骨龄法等。目前国外普遍采用TW评分法。国内也有该评分法的应用报道。主要应用于体育和儿科临床实践中。法医临床学实践中常用六大关节判别方程法推断骨龄和活体年龄推断。其他还有利用牙齿内天冬氨酸的消旋化、骨密度检测以及端粒末端DNA片段长度的变化等年龄推断方法。
