A recent European Molecular Biology Laboratory Conference on Science and Society entitled "Time & Aging--Mechanisms & Meanings" fascinated scientists from different research areas as well as nonscientists. Topics discussed included not only the biological aging process but also the psychological effects of aging and social influences that affect this process.  相似文献

Abstract

This paper examines the role of arts and crafts in reconstructing communities after times of upheaval, their use in creating employment opportunities, and their impact on the nature of South African art history. It looks at craft initiatives during and after the Johannesburg World Summit on Sustainable Development in 2002, and draws parallels with early twentieth-century initiatives, particularly those of Florence Phillips, who founded the Johannesburg Art Gallery in 1910, Emily Hobhouse, who established Boer home industries, and the South African National Union, which promoted the manufacture and use of local products.  相似文献

Within the existing body of research, the information pertaining to sexual compulsivity (SC) among women, both homo- and heterosexual, remains rather limited in comparison to men. The aim of this study was to assess the prevalence of SC in a community sample of gay and bisexual men and lesbian and bisexual women and to identify differences in sexual practices based on classification as sexually compulsive within gender. Supporting previous research, the findings indicated that gay and bisexual men were significantly higher in SC when compared to lesbian and bisexual women. Similarly, sexually compulsive gay and bisexual men were more likely to report drug use with sex than their non-sexually compulsive peers, suggesting that “party n' play” may play a larger role for men with SC. In addition, the findings demonstrated empirical support for the proposition that lesbian and bisexual women with symptoms of SC were more likely to engage in specialized sexual behaviors in comparison to their non-sexually compulsive peers. These data suggest that SC manifests differently in gay, lesbian, and bisexual men and women.  相似文献

ABSTRACT

An emerging body of evidence shows that parents’ non-standard work schedules have a detrimental effect on children's well-being. However, only a limited number of studies have investigated mediating factors that underpin this association. Likewise, only a few studies have examined the impact of fathers’ non-standard work schedules on children's well-being. Based on data from the Families in Germany Study (FiD), this study aimed to address these research gaps. The sample consists of parents and their children at ages 7–8 and 9–10 (n?=?838 child observations in dual-earner families). The data were collected in the years 2010–2013. Non-standard work hours were defined as working in evenings and or at night (every day, several times a week, or changing as shifts). Children's social and emotional well-being was measured with the Strengths and Difficulties Questionnaire (SDQ). The findings show that both mothers’ and fathers’ evening and night work schedules are linked to an increase in children's externalizing and internalizing behavior and that this association is partially mediated by mothers’ and fathers’ harsh and strict parenting, with a stronger mediation effect for fathers parenting.  相似文献

This paper explores the lesser-known histories and present-day realities of small towns and non-metropolitan areas in the internal provinces of South Africa. It is different inasmuch as it focuses on transformations that have taken place at the local level, and where possible, generalises from these, rather than following the normal route taken by social scientists – at least from 1994, which has been to examine them from the top down. One feature of such changes has been the growth of gated communicates across the length and breadth of South Africa, but there are many more. One reason for their anonymity is that their evolution has been gradual and corpuscular, that they have become unconsciously familiar and are left unexamined. Another is our collective preoccupation with the metropolitan areas rather than the smaller localities where such processes are subterranean and confined. This paper presents very briefly some of the results of the researchers of the Local Histories and Present Realities programme over the past five years, in 19 separate centres. It examines the history and present circumstance of chiefdoms of Ga-Mphahlele and reveals the surprise finding that much of recent and contemporary politics revolve around events 200 years old. An analogous situation has arisen in Venda as well as in Mpumalanga and elsewhere, where a combination of new legislation to revive chiefly powers, and land reclamation legislation have lent a new legitimacy to chiefly powers, and inspired hundreds of phantom – and time-consuming – quests. Another massive development which has gone on around us but whose internal dynamics have never been observed is the rise of game hunting and ranching all over the interior of South Africa. This is a monster subject which is likely to have influence on all of our lives into which our group is now in a position to offer insights. A change of equal proportions is the rise of mining all over the interior Bushveld Igneous Complex – Mokopane is a good example of this and the huge social consequences this has brought in its wake. One final theme which embraces all the communities that we have studied is the local histories of transformation – collectively the most important – since 1994. This is almost entirely hidden to a wider world, including the transformed positions of local Indian residents.  相似文献

The study examined whether differences in gender and family status affect parental caregiving disposition and acceptance of children among parents of children in mid-childhood. The number of participants were 122 divorced-custodial fathers, 107 married fathers, 85 divorced-custodial mothers, and 82 married mothers (n?=?398). A comparison among four groups of parents revealed the following gender differences: mothers scored higher on anxious caregiving and parental acceptance than fathers, and lower on avoidant caregiving. Regression analysis indicated that the higher the caregiving avoidance or anxiety, the lower the parental acceptance. Family status moderated parental acceptance, as avoidant caregiving was associated with reduced parental acceptance among married parents, but not among divorced custodial parents. The finding that avoidant caregiving was not associated with reduced acceptance among divorced custodial parents implies that their parental acceptance behaviors toward their children are affected by their parental status as sole custodial parent, and the associated responsibilities, rather than by gender.  相似文献
