Filial piety has remained a cornerstone of aged care in Chinese communities for at least 2,000 years. This paper reviews understandings and practices of filial piety in China and among Chinese migrants to western countries. Five dimensions of filial piety are considered: living arrangements, support, respect, ancestral worship and gender norms. Although the meaning of and practices associated with filial piety may have changed over time, the ideal of filial piety is still highly relevant to aged care in Chinese communities today.  相似文献

We examine spatial patterns of mass political participation in the form of volunteering and donating to a major statewide election campaign. While these forms of participation are predictably associated with the political and socioeconomic characteristics of the precincts in which the participants reside, we find that these statistical relationships are spatially nonstationary. High-income neighborhoods, for example, are associated with stronger effects on participation at some locations more than at others. By using geographically weighted regression (GWR) to specify local regression parameters, we are able to capture the heterogeneity of contextual processes that generate the geographically uneven flow of volunteers and contributors into a political campaign. Since spatial nonstationarity may well be a rule rather than an exception in the study of many political phenomena, social scientific analyses should be mindful that relationships may vary by location.  相似文献

Has democracy promoted poverty alleviation and equity‐enhancing reforms in Brazil, a country of striking inequality and destitution? The effects of an open, competitive political system have not been straightforward. Factors that would seem to work toward this goal include the voting power of poor people, the progressive 1988 Constitution, the activism of social movements, and governance since 1995 by presidents affiliated with center‐left and left parties. Yet these factors have been counterbalanced by the strong political influence and lobbying power of organized interests with a stake in preexisting arrangements of social protection and human capital formation. An analysis of four key federal sectors, social security, education, health care, and public assistance, illustrates the challenges for social sector reforms that go beyond raising basic living standards to enhancing socioeconomic inequality.  相似文献

Consistent with the view that adolescent relationships are established in the context of important characteristics of their social networks, we examined the effects of adolescents’ experiences of parenting (psychological control and positive monitoring) and of peer aggression and victimization, on their self reports of dating victimization and aggression. We also examined the effects of individual differences in emotional and behavioral problems. We used questionnaire data from a population-based sample of youth 12–18 years old who were in dating relationships (n = 149). Parental monitoring emerged as a protective factor in reducing both dating victimization and relational aggression. Our findings also point to a significant transfer of aggression in peer relationships to relational aggression in dating relationships.

Educational attainment in adolescence is of paramount importance for attaining higher education and for shaping subsequent life chances. Sociological accounts focus on the role of differences in socioeconomic resources in intergenerational reproduction of educational inequalities. These often disregard the intergenerational transmission of cognitive ability and the importance of children’s cognitive ability to educational attainment. Psychological perspectives stress the importance of cognitive ability for educational attainment but underemphasize potentially different roles of specific socioeconomic resources in shaping educational outcomes, as well as individual differences in cognitive ability. By integrating two strands of research, a clearer picture of the pathways linking the family of origin, cognitive ability, and early educational outcomes can be reached. Using the population-based TwinLife study in Germany, we investigated multidimensional pathways linking parental socioeconomic position to their children’s cognitive ability and academic track attendance in the secondary school. The sample included twins (N?=?4008), respectively ages 11 and 17, and siblings (N?=?801). We observed strong genetic influences on cognitive ability, whereas shared environmental influences were much more important for academic tracking. In multilevel analyses, separate dimensions of socioeconomic resources influenced child cognitive ability, controlling parental cognitive ability. Controlling adolescent cognitive ability and parental cognitive ability, parental socioeconomic resources also directly affected track attendance. This indicated that it is crucial to investigate the intertwined influences on educational outcomes in adolescence of both cognitive ability and the characteristics of the family of origin.  相似文献

Past research has shown that adolescent peer groups make a significant contribution to shaping behavior but less is known about the role of peer groups in adolescent dating relationships. This longitudinal study examined the contribution of aggressive peer group norms on relationship quality and dating violence among dating adolescents. At the beginning of the school year (T1) and 6 months later (T2), participants (n = 1,070; M age = 15.45; 49 % Female) provided self-reports of attitudes towards aggression, and physically- and relationally-aggressive behaviors. Peer groups were identified using a peer-nomination technique and aggressive behaviors and attitudes were averaged across peer groups. Participants with dating experience (n = 598) reported on the frequency of their experience with dating violence (both as a victim and perpetrator). Multilevel analyses indicated that peer group relational aggression at T1 positively predicted dating abuse victimization and perpetration, and negatively predicted relationship quality at T2, beyond individual predictions. An unexpected finding was that membership in physically aggressive peer groups at T1 was associated positively with relationship quality at T2. Results point to the importance of the peer group in shaping adolescent dating experiences.  相似文献

Threat appraisals—individuals’ perceptions of how stressful situations may threaten their well-being—are an important but understudied mechanism that could explain links between peer victimization and adjustment. The goal of the present study was to examine relationships between physical and relational victimization by peers, threats to the self, and aggression, anxiety, and depression to better understand the cognitive evaluations that make youth vulnerable to negative adjustment. The sample comprised two cohorts of African American adolescents (N = 326; 54 % female; M = 12.1; SD = 1.6) and their maternal caregivers, who participated in three waves of a longitudinal study. Path models revealed significant direct effects from Time 1 relational victimization, but not physical victimization, to Time 2 threat appraisals (i.e., negative self-evaluations and negative evaluations by others), controlling for Time 1 threat appraisals. Significant direct effects were found from Time 2 threats of negative evaluations by others to Time 3 youth-reported aggression, controlling for Time 1 and Time 2 aggression. Significant direct effects also were found from Time 2 threats of negative self-evaluations to T3 youth-reported depression, controlling for Time 1 and Time 2 depression. Overall, findings highlight the need to consider the role of threats to the self in pathways from peer victimization to adjustment and the implications these appraisals have for youth prevention and intervention efforts.  相似文献

This article presents findings from a randomized experiment conducted in four Canadian provinces to measure the effects of a generous financial incentive that was designed to promote rapid re‐employment among workers who were displaced from their jobs by changing economic conditions. The incentive tested was an earnings supplement which, for as long as 2 years and as much as $250 weekly, would replace 75 percent of the earnings loss incurred by displaced workers who took a new lower‐paying full‐time job within six months of receiving a supplement offer. Findings from the experiment indicate that although persons offered the supplement understood its terms and conditions, only 2 out of 10 actually received supplement payments. Furthermore, the supplement offer had little effect on job‐search behavior, employment prospects, or receipt of unemployment insurance. Nevertheless, persons who received supplement payments benefited from them substantially. On average, they received payments for 64 weeks, totaling $8,705. © 2001 by the Association for Public Policy Analysis and Management.  相似文献
