中国农村地区的家庭禀赋与外出务工劳动力回流 总被引:5,自引:0,他引:5
中国农村地区家庭禀赋对个人的行为决策有着重要的影响,需要学术界予以更多的关注。为了考察外生性的家庭禀赋对劳动力就业流动的影响,文章通过构建新生代外出务工劳动力和户主子女的回流决策两个计量模型来进行经验论证。分析结果表明,农村劳动力的迁移选择是综合考虑家庭禀赋状况的理性决策,尤其是对于年轻一代的外出劳动力。家庭经济资本的增加会阻碍家庭外出务工成员的回流。外出劳动力回流的概率起初随着家庭人力资本和家庭自然资本的增长而上升,达到一定程度后开始下降。家庭成员只有拥有较为丰富的人力资本,外出务工劳动力才能对家庭社会资本加以充分利用。另外,分析显示年轻一代劳动力和第一代劳动力对家庭社会资本和自然资本的利用是有差异的。 相似文献

The different in the fertility of the rural and urban and future changing trend are very important questions to understand China’s population problem. This paper calculates the fertility of the urban and the rural since 2000 based on the statistical data and compares the fertility rate in the urban and the rural population since 2000. The finding shows that the TFR in the rural is less than 1.8 while the TFR in the urban is less than 1.3 and the difference is narrowing year by year. The fertility difference is mainly caused by the second child, generally speaking the second child fertility tend to increasing slightly while the first child fertility shows dramatic fluctuations because of the Chinese folk culture, the fertility fluctuation in the rural is much dramatic than that in the urban. The mean age at childbearing (MAC) has been delaying in both the rural and the urban areas in the decade. 相似文献

Family foster care is the option of choice for children in need of out‐of‐home care in Flanders and the Netherlands. Foster care is however a vulnerable intervention, and questions can be raised as to its efficacy. Although the literature on placement breakdown has made significant progress during the last years, empirical knowledge regarding breakdown in Flanders and the Netherlands remains scant. Consequently, this study aimed at investigating prevalence and precursors of breakdowns in long‐term foster care, the duration of placement before breakdown, and the association of child and placement characteristics with breakdown. Case files of 271 Dutch and 309 Flemish foster children were analysed with a coding scheme designed for this study. After 6 years, 398 placements had terminated: 169 placements broke down and 229 placements ended positively. Placements broke down mainly because of behavioural problems of the foster child, foster parents' parenting problems, and conflicts between birth and foster parents. Foster children with behavioural problems, older foster children, foster children denied treatment, and foster children in care because of sexual abuse were more at risk of breakdown. Assessing these factors is important when evaluating the appropriateness of a family foster care placement. 相似文献

Abstract Objective: To assess the use of alcohol screening tools across US colleges. Participants: Directors of health services at 333 four-year colleges. Methods: An online survey was conducted regarding the use of alcohol screening tools. Schools reporting use of formal tools were further described in terms of 4 tools (AUDIT, CUGE, CAPS, and RAPS) that the authors judged to be the most favorable based on prior empirical comparative studies. Results: Forty-four percent of colleges reported use of at least 1 formal alcohol screening tool and nearly all of these used a tool appropriate for college students. However, less than half of the 44% of colleges that used a screening tool used 1 of the 4 most favorable tools. Conclusions: Continued efforts are needed to encourage colleges to use the most effective available screening tools to identify alcohol-related problems that require intervention among students. 相似文献

Abstract Objective: In this study, the relationships between measures of interpersonal resilience, intrapersonal resilience, and mental health were examined with respect to academic and social integration, key determinants of academic persistence. Participants: A sample (n = 605) of undergraduate students was recruited from 2 midwestern universities during the 2007–2008 academic year. Methods: Hierarchal (or sequential) regression analysis examined whether the inter- and intrapersonal resilience and mental health measures contributed to explaining variance in the response variables of university cumulative grade point average (GPA) and university sense of belonging. Results: The intrapersonal resilience factors contributed to explaining variance in cumulative GPA in addition to aptitude and achievement. Furthermore, there was a strong statistical correlation between the inter- and intrapersonal resilience factors and mental health. Conclusions: The demands in college are significant and there is a need for more research on the concept of resilience as it relates to college health and academic persistence. 相似文献

Abstract Background: Studies indicate that a small percentage of rapes are reported to law enforcement officials. Research also suggests that rapes perpetrated by a stranger are more likely to be reported and that rapes involving drugs and/or alcohol are less likely to be reported. College women represent a unique and understudied population with regard to reporting rape. Methods: In the current study, the authors interviewed a national sample of 2,000 college women about rape experiences in 2006. Results: Only 11.5% of college women in the sample reported their most recent/only rape experience to authorities, with only 2.7% of rapes involving drugs and/or alcohol reported. Minority status (ie, nonwhite race) was associated with lower likelihood of reporting, whereas sustaining injuries during the rape was associated with increased likelihood of reporting. Discussion: Reporting, particularly for rapes involving drugs and alcohol, is low among college women. Implications for policy are discussed. 相似文献

Moderators of the Relationship Between Physical Activity and Alcohol Consumption in College Students

Abstract Objective: Among college students, several studies have found a positive relationship between physical activity and alcohol use. The current study tested gender, Greek status, and ethnicity as potential moderators of the physical activity-alcohol use relationship. Participants: Participants were college freshmen (n = 310) endorsing alcohol/drug use. Methods: Students completed questionnaires assessing a number of health behaviors. Results: Results indicated that gender and Greek status were significant moderators of the relationship between physical activity and alcohol consumption. There was a positive relationship between physical activity and alcohol use for men and Greeks, but not for females and non-Greeks. Conclusions: These findings suggest that exercise does not serve as a protective factor for any of the subgroups of college students studied and is positively associated with drinking among college students who are men and/or involved with the Greek system. 相似文献

Abstract Objective: Evaluation of the Brief Alcohol Screen and Intervention in College Students (BASICS) in a university primary care setting. Participants/Methods: Undergraduates (N = 449) participated in BASICS and electronic surveys assessing frequency/quantity of alcohol and drug use, psychosocial and mental health outcomes, and demographic information. Data were collected at baseline and 6-month follow-up between August 2006 and August 2008. Results: Drinking and drug use decreased between baseline and 6 months. Participants reported an increase in protective factors and in readiness to change alcohol-related behaviors, and a decrease in alcohol-related consequences and in distress symptoms. Heavy episodic drinking at baseline significantly moderated the changes in number of drinks in a typical week and in a typical weekend, and number of drinks on the occasion drank most on a weekend. Conclusions: BASICS can be implemented in a primary health care setting and university students may reduce their alcohol and/or drug use. 相似文献
