Integrins are cell surface receptors that mediate adhesion to the extracellular matrix. In this Perspective, we focus on the recent finding that a decrease in the levels of integrins yields fruit flies that retain youthful mobility as they age and display an increased mean life span. We discuss how the reduction of integrin activity might lead to the observed changes. 相似文献

Siblings are often not included in treatment programs for children who have been sexually abused. This article describes the necessity of including siblings in the treatment of victims of child sexual abuse. Including siblings in treatment permits families to realize the maximum benefits of therapy for the victim as well as each family member. Theoretical and practical reasons to include siblings in treatment are discussed (i.e., preventing future abuse, providing support for siblings, teaching siblings to refrain from victim-blaming). Case examples using a particular intervention approach at The Family Learning Program and results of client satisfaction surveys are described. 相似文献

Volunteer work and well-being 总被引:2,自引:0,他引:2
Using two waves of panel data from Americans' Changing Lives (House 1995) (N = 2,681), we examine the relationships between volunteer work in the community and six aspects of personal well-being: happiness, life satisfaction, self-esteem, sense of control over life, physical health, and depression. Prior research has more often examined the effects of voluntary memberships than of volunteer work, has used cross-sectional rather than longitudinal data, and, when longitudinal, has emphasized social causation over selection effects. Focusing only on the consequences of volunteer work overlooks the antecedents of human agency. People with greater personality resources and better physical and mental health should be more likely to seek (or to be sought for) community service. Hence, we examine both selection and social causation effects. Results show that volunteer work indeed enhances all six aspects of well-being and, conversely, people who have greater well-being invest more hours in volunteer service. Given this, further understanding of self- versus social-selection processes seems an important next step. Do positive, healthy people actively seek out volunteer opportunities, or do organizations actively recruit individuals of these types (or both)? Explaining how positive consequences flow from volunteer service may offer a useful counterpoint to stress theory, which has focused primarily on negative life experiences and their sequelae. 相似文献

This article describes the development, implementation, and replication of a group-based parenting program for families affected by substance abuse. The Nurturing Program for Families in Substance Abuse Treatment and Recovery improves parenting, as measured on objective scales; enhances parents' satisfaction and competence, as measured by participant reports; and is based on principles demonstrated to be effective in reducing risk of both child abuse and neglect and substance abuse for both parents and children. 相似文献

To summarize articles with the depth and range of the nine in this collection is difficult. What the articles demonstrate as a whole is that a great deal of activity is under way in the arena of connecting child welfare and substance abuse services, with a growing body of documentation accompanying it. The articles bode good news in that they indicate a broadening awareness of the interconnectedness of these issues, and they highlight a number of creative and effective programs that have been established to mitigate the problems. Tremendous challenges-from funding to outcomes research-however, are also made evident in this body of work. 相似文献

Some policy makers and policy analysts have proposed that Social Security should be privatized to enable participants to achieve higher returns through investment in the stock market. How well individual retirees would fare financially under a privatized system largely depends on their decision to invest in the equity market, rather than in other types of investment vehicles. For that reason, it is important to investigate the degree to which minority people are currently investing in this market. This article presents the findings of a study that compared the investment behavior of black and Hispanic people aged 51 to 61 with the investment behavior of their white counterparts. The major findings indicate that black and Hispanic people: (a) are less likely to invest in the equity market than are white people, and (b) tend to invest smaller percentages of their assets in the equity market. Implications for policy are discussed. 相似文献
