Time spent on social media and making online comparisons with others may influence users’ mental health. This study examined links between parental control over the time their child spends on social media, preadolescents’ time spent browsing social media, preadolescents’ appearance comparisons on social media, and preadolescents’ appearance satisfaction, depressive symptoms, and life satisfaction. Preadolescent social media users (N?=?284, 49.1% female; aged 10–12) and one of their parents completed online surveys. Preadolescents, whose parents reported greater control over their child’s time on social media, reported better mental health. This relationship was mediated by preadolescents spending less time browsing and making fewer appearance comparisons on social media. Parental control over time spent on social media may be associated with benefits for mental health among preadolescents.  相似文献

In the recent past, governance reforms in India have resulted in the government and corporate sectors making serious efforts to enhance and showcase their accountability to their principals, namely citizens and shareholders. Similarly, NGOs have been pushed to demonstrate their accountability to multiple stakeholders, namely donors, communities and most importantly, the state. This viewpoint highlights this transition and also reflects on the changing contours of NGO accountability debates in India.  相似文献

There is strong evidence that chronic, systemic inflammation hastens onset of the diseases of old age that ultimately lead to death. Importantly, several studies suggest that childhood adversity predicts chronic inflammation. Unfortunately, this research has been plagued by retrospective reports of childhood adversity, an absence of controls for adult stressors, and a failure to investigate various competing models of the link between childhood adversity and chronic inflammation. The present study was designed to address these limitations. Using 18 years of data collected from 413 African Americans (58% female) included in the Family and Community Health Study, hierarchical regression analyses provided support for a nuanced early life sensitivity explanation for the link between early adversity and adult chronic inflammation. Controlling for health risk behaviors and adult SES, late childhood (ages 10–12) adversity amplified the association between adult adversity (age 29) and chronic inflammation. This interaction operated in a domain-specific fashion. Harsh parenting amplified the relation between intimate partner hostility and inflammation, whereas early discrimination amplified the relation between adult discrimination and inflammation. These findings suggest that individuals may be primed to respond physiologically to adverse adult circumstances that resemble those experienced earlier in life.

The policy movement is unified by a common interest in the improvement of policy decisions through scientific inquiry. The movement is differentiated, however, because this common interest is highly ambiguous and subject to interpretation from different perspectives. This paper applies a policy sciences perspective to the movement's disappointments over the last few decades, and in particular, the failure to realize earlier aspirations for rational, objective analysis on the more important and controversial policy issues. The paper offers a definition and diagnosis of the underlying problem, and suggests what can be done about it as a matter of individual and collective choice.  相似文献

The association of pubertal maturation with internalizing and externalizing symptoms was examined with a sample of 867 African-American 10 – 12-year-old children. Children reported their pubertal development status and timing using a self-report questionnaire, and symptoms were assessed through diagnostic interviews with the children and their primary caregivers. Pubertal status and timing were significantly associated with children's reports of the internalizing symptoms of social anxiety disorder, generalized anxiety disorder, and major depression and with the externalizing symptoms of oppositional defiant disorder, attention deficit disorder, and conduct disorder. Pubertal development also was associated with caregivers’ reports of children's externalizing symptoms. The pubertal transition was associated with internalizing and externalizing symptoms in both boys and girls.Xiaojia Ge is Professor at the University of California, Davis.

This paper studies extremist behaviour, and its connection to authoritarianism. I divide extremists into two groups, leaders, who demand extremist acts such as assassinations, suicide terror or other forms of political violence from followers, who supply them. I assume that both the leaders of extremist groups and their followers are rational. The paper looks at three examples: Communism, Nationalism and Islamic Fundamentalism. I show that leaders with extreme ideologies also tend to adopt violent methods when there is an indivisibility between the intermediate goal of the group and its ultimate goal. Turning to followers, the most important innovation of the paper is a simple model which explains how it is possible for a person to rationally commit suicide to further the goals of a group. The most important policy implications of the paper are, firstly, that one should look at the goals of extremist group in order to understand their actions. If one can un-bundle the goal or make the indivisible divisible, then there may be ways to provide these goals in a way which satisfies some of the potential supporters of the group and thus dries up support for the grander ambitions of the leaders of extremist groups. Secondly, the provision of programs which foster social cohesion tends to dry up an important motive for extremist activity: the desire for solidarity. Thirdly, policy towards terrorists should combine the use of “carrot” and “stick”. Finally, I argue that authoritarian regimes rather than democracies or totalitarian regimes are the most likely sources of suicide terror. So democracy is indeed part of the solution to the problem of suicide terrorism.  相似文献

Abramson and Inglehart find a significant trend toward postmaterialist values in Western Europe, which they argue is largely driven by the gradual processes of generational replacement. Clarke, Dutt, and Rapkin argue that this trend is a methodological artifact of the wording of Inglehart's four-item measure of materialist/ postmaterialist values. They claim that because this battery does not include a question about unemployment, in periods of high unemployment respondents tend to choose postmaterialist goals. The long-term trend toward postmaterialism in Western Europe, they argue, results from rising levels of unemployment during the past two decades. Abramson and Inglehart point out that increases in inflation have a short-term impact on decreasing postmaterialism, but maintain that the positive relationship between unemployment and postmaterialism is spurious. As this analysis shows, Clarke, Dutt, and Rapkin find a positive relationship between unemployment and postmaterialism by building a model that has little theoretical justification and that is not robust to changes in specification. As this analysis demonstrates, unemployment is actually linked with support for materialist goals, and the trend toward post-materialism is robust in the face of alternative time frames, models, and specifications. The weight of the evidence demonstrates that the long-term trend toward postmaterialism in Western Europe is driven by generational replacement.  相似文献

The purpose of this study was to examine differences in empathy between offender and nonoffender youth. Seventy-six male and 33 female juvenile offenders between the ages of 12 and 18 years and 33 male and 33 female nonoffenders between the ages of 15 and 19 years comprised the samples for this study. Measures of empathy, altruism, and social support were administered to all participants and then the participants were analyzed for status group differences. Only 1 dimension of empathy, emotional tone, was found to be significantly different based on group status. Gender differences were found for both status groups for another dimension of empathy, personal distress. Among offender and nonoffender youth, females yielded higher scores in personal distress than did males. Emotional tone and family structure were found to be the most predictive variables of offender status. Findings were discussed based on previous research and implications for interventions were addressed.Evaluation and Special Programs  相似文献
