Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted.  相似文献

Despite United Russia’s (Edinaya Rossiya—UR) dominance in repeated Russian legislative elections, the correlates of the party’s electoral support remain noticeably understudied beyond the influence of electoral manipulation. I pinpoint the specific contours of UR’s strongholds in the two most recent parliamentary elections in Russia—2007 and 2011—focusing on raion- and regional-level correlates of the vote using an original dataset. UR has been undergirded by geographically concentrated ethnic minorities and the countryside, and these patterns of support have persisted even in the absence of fraud, suggesting that the dominant party’s electoral windfalls cannot be attributed solely to electoral malfeasance.  相似文献

Recent advancements in technology (e.g., social networking, texting) have created new ways for dating youth to relate to one another, including in abusive ways via “cyber dating abuse.” Cyber dating abuse is a form of teen dating violence that overlaps with other types of abuse (e.g., psychological) but also has several unique characteristics. Given the phenomenon’s limited presence in dating violence literature, we focus on identifying how experiencing cyber dating abuse relates to youths’ individual behaviors and experiences (e.g., substance use, sexual activity), psychosocial adjustment, school connection, family relationships, and partner relationships. A total of 3,745 youth (52 % female, 74 % White) in three northeastern states participated in the survey and reported currently being in a dating relationship or having been in one during the prior year. We found that experiences of cyber dating abuse were most significantly correlated with being female, committing a greater variety of delinquent behaviors, having had sexual activity in one’s lifetime, having higher levels of depressive symptoms, and having higher levels of anger/hostility. Further, cyber dating abuse appeared somewhat more strongly related to depressive symptoms and delinquency than did other forms of teen dating violence and abuse.  相似文献

‘Meritocracy’ continues to unfold as both core conceptual framework and political ideal of the language of social mobility. In recent decades, politicians of various hues have declared it a sine qua non of the so-called ‘classless society’. The longer trajectory of postwar discourses of equality reveal a more chequered conceptual past. Its origins in the forums of revisionist social democracy of the 1950s, and subsequently popularised in the writings of social democratic polymath, Michael Young, are much more circumspect. The article considers pivotal contributions and developments of this conceptual history and trajectory. It considers the origins and emergence of meritocracy as a dimension of discourses of equality in the 1950s, and the formative contribution of Michael Young, reaction and responses on the left to his 1958 seminal work, The Rise of the Meritocracy, and the subsequent ‘meritocratic turn’. In spite of its satirical origins and warnings of dire social consequences, meritocracy presently enjoys a confirmatory position as a concept of opportunity and social mobility, as an embedded ideal of social organisation and means of allocating differential rewards.  相似文献

Current explanations of effective voter mobilization strategies maintain that turnout increases only when a potential voter is persuaded to participate through increased social connectedness. The connectedness explanation does not take into account, however, that registered voters, by registering, have already signaled their interest in voting. The theory presented in this article predicts that impersonal, noticeable   messages can succeed in increasing the likelihood that a registered voter will turn out by reminding the recipient that Election Day is approaching. Text messaging is examined as an example of an impersonal, noticeable communication to potential voters. A nationwide field experiment (n = 8,053) in the 2006 election finds that text message reminders produce a statistically significant 3.0 percentage point increase in the likelihood of voting. While increasing social connectedness has been shown to positively affect voter turnout, the results of this study, in combination with empirical evidence from prior studies, suggest that connectedness is not a necessary condition for a successful mobilization campaign. For certain voters, a noticeable reminder is sufficient to drive them to the polls.  相似文献
