Despite positive and negative emotions being equally important predictors of adolescent wellbeing, research examining positive emotions is limited. In 4582 adolescents (69.4% females; age M?±?SD?=?14.55?±?1.74 years), we used structural equation modelling to examine associations between self-reported sleep duration and quality with positive affect, negative affect, and happiness, controlling for age and sex. Overall, sleep quality displayed stronger associations with all measures of emotions compared to sleep duration. Shorter sleep was more specifically associated with lower positive emotions (happiness, followed by positive affect), whereas poorer sleep showed stronger associations with negative affect. Protecting sleep duration may promote positive emotions and enhancing sleep quality may reduce mood disturbances. Future research could incorporate both positive and negative emotions to better understand adolescents’ wellbeing.  相似文献

Abstract

This article analyses party strategies during the campaign for the Dutch general election of March 2017, making use of issue-yield theory. It investigates whether parties strategically emphasise high-yield issues, by juxtaposing the issue opportunities provided by voters with parties’ issue emphasis during the campaign. More specifically, it asks whether parties strategically emphasised issues that were expected to reward them electorally. Analysing voter preferences and party campaign data, it is found that parties and most of their constituencies show high ideological consistency, that parties emphasise mostly positional issues and thus choose a conflict-mobilising strategy, and that most parties emphasise high-yield issues rather than following the general political agenda. Four small parties that won significantly behaved strategically while the social democrats – who severely lost – hardly did. The findings imply that the issue-yield framework can help to explain the election result in the fragmented Dutch multi-party context.  相似文献

In the last years, ageing – or rather active ageing – has become a highly popular issue. In contrast to the disputed activation in labor market policies, the activation of old age seems to be a win-win-situation that benefits everyone. However, embedded in two highly topical debates – demographic change and activation-based welfare state reform – the conditions of the popularization of active ageing remain a blank within the German discussion. This concerns the specifics of old age activation as well as the power-related implications and the normalizing and standardizing consequences of this re-negotiation of old age. It is the aim of this article to discuss these blanks theoretically, paying reference to Anglo-Saxon gerontology, to works on active society and to gender theory on sameness and difference.  相似文献

Contemporary politicians face immense rhetorical and communicative challenges. Performing on the intertwined stages of politics, media (including Internet) and everyday life, they need to master diverse and contrasting repertoires of talk. Political communication research, at present, has ignored the question of how politicians face and experience these challenges, and how they reflect on the new communicative field. In this article, we begin to redress this situation by analysing and comparing the motives, experiences and reflections of politicians who appeared in the British satirical TV show, Have I Got News for You, and its Dutch adaptation, Dit was het Nieuws. Based on in-depth interviews with seven Dutch and 14 English MPs, we conclude that they draw from three repertoires to legitimise and reflect on their participation: a strategic, indulgent and anti-elitist repertoire. The first repertoire is predictable in the context of current political communication research, whereas the latter two add new dimensions of pleasure and bottom-up representation to it.  相似文献

Research indicates that subjective perceptions of socioeconomic status (SES) affect aspects of health and behavior. There has been little research attention to how objective (e.g., education) and subjective aspects of SES may differ in their influence on the substance use of adolescent immigrants. The present study examined whether the associations between subjective SES and substance use, and between parental education and substance use varied by immigrant generation. Data were derived from the 2011 Ontario Student Drug Use and Health Survey, a representative survey of students in the 7th to 12th grade. The sample for this study consisted of 9177 students 12–19 years of age; 48.4 % were female, 66.4 % were White/European, 5.2 % Black/Afro-Caribbean, 16.4 % Asian and 12 % other. Results indicated that subjective SES was more strongly associated with cannabis and alcohol use among first-generation immigrants than among adolescents of other immigrant generations even after adjusting for parental education. First-generation immigrants with low subjective SES had a lower probability of cannabis and regular alcohol use, but there was no difference in use between immigrant generations at high subjective SES. The associations between parental education and cannabis and alcohol use did not significantly vary with immigrant generation. The findings highlight the importance of status beliefs among adolescents, particularly among first-generation immigrants, and suggest that further research attention to such beliefs would enhance our understanding of SES and its links to adolescent health risk behaviors.  相似文献

Although the relation between family relationships and the timing of sexual debut has been the focus of many studies, research on mediating factors is scarce. This study examines whether low levels of family cohesion result in an earlier onset of romantic and sexual experiences, and whether the link between family cohesion and an early sexual debut is mediated by early romantic initiation. A longitudinal sample of 314 adolescent girls and 222 boys, aged 12–17 at Wave 1, completed questionnaires at three measurement points with three year intervals. The results showed that sexual debut followed romantic initiation for 77% of the participants. For early adolescent females (aged 12–14), high levels of family cohesion resulted in a later sexual debut and this association was fully mediated by a delay of romantic initiation. Among boys and older girls, timing of romantic initiation did not mediate the link between family cohesion and timing of sexual initiation. Early adolescent girls who have negative relationships with their parents turn to romantic relationships for intimacy and support, which subsequently provide the opportunity for an early sexual debut. Low levels of family cohesion thus primarily precipitate romantic initiation and sexual initiation appears to be secondary to this process among girls in this age group.  相似文献
