Children and adolescents in developed countries are heavily immersed in digital media, creating an inexpensive, far-reaching marketing opportunity for the food industry and the gaming industry. However, exposure to nonnutritious food and beverage advertisements combined with the use of stationary media create a conflict between entertainment and public health. Using the popular digital gaming platforms advergames (online games that market branded products) and exergames (video games that involves gross motor activity for play) as exemplars, the following article provides an analysis of the negative and positive health impacts of digital gaming as they relate specifically to overweight and obesity outcomes for children and adolescents. Theoretical explanations including the food marketing defense model, persuasion knowledge model, and social cognitive theory are used to explain the influence of gaming on young players' health. Throughout the article, we discuss the role of public policy to encourage the development and use of health-promoting digital games as an innovative, effective tool to combat the pediatric obesity crisis.  相似文献

A Cramér-von Mises type statistic for testing bivariate independence, proposed by Hoeffding (1948) and by Blum, Kiefer, and Rosenblatt (1961), is examined in greater detail. The statistic is decomposed into components in the manner of Durbin and Knott (1972), and the components are shown to be related to linear rank statistics. Asymptotic power properties of the Hoeffding statistic and its components in testing for independence with bivariate normal random observations are described; a Monte Carlo study comparing these statistics with other nonparametric statistics for bivariate independence is also reported.  相似文献

ABSTRACT

Objective: Develop and test an online survey to assess campus readiness to adopt smoke- and tobacco-free (SF/TF) policies. Participants: Key informants (N = 18) at four campuses in Kentucky without a SF/TF policy recruited April 2015. Methods: Cross-sectional design. The survey assessed six dimensions: knowledge about SF/TF policies; leadership for campus policy; resources for policy development; campus climate surrounding tobacco issues; existing tobacco policies; and political climate for campus policy development. Dimension raw scores were rescaled to range from 0–1 and summed to determine overall stage of readiness (0–6). Results: Political climate was highest dimension across all campuses (0.83–1.0). Knowledge dimension ranked lowest (0.0–0.50). Overall readiness scores ranged from 2.53–3.94; two campuses in preplanning and two in preparation. Conclusions: Development of the online measure is timely considering the impetus to implement SF/TF policies. Findings reinforce that campuses are at varying stages of implementing these policies, and stage-based interventions are necessary.  相似文献

Abstract. Objectives: This study examined whether childhood bullying victimization was associated with psychosocial and academic functioning at college. Participants: The sample consisted of 413 first-year students from a large northeastern university. Methods: Students completed an online survey in February 2012 that included items assessing past bullying involvement, current psychosocial and academic functioning, and victimization experiences since arriving at college. Results: Regression analyses indicated that reports of past bullying and other peer victimization were associated with lower mental health functioning and perceptions of physical and mental health, but were not associated with perceptions of social life at college, overall college experience, or academic performance. Conclusions: Childhood bullying victimization is associated with poorer mental and physical health among first-year college students. Colleges should consider assessing histories of bullying victimization, along with other past victimization exposures, in their service provision to students.  相似文献

Previous research suggests that international volunteer service may have both positive and negative effects on host organizations. Applying a capacity-building perspective, this study uses semistructured interviews to ask staff in hosting organizations to identify the main outcomes of short-term volunteer service. These views were compared with perspectives of staff from matched organizations that do not host international volunteers. Findings suggest that international volunteers may increase organizational capacity by supplying extra hands, providing technical and professional skills, contributing tangible resources, and enhancing intercultural understanding. Volunteers may also challenge organizations as they absorb staff time and resources. Staff members from both types of organizations identify individual and institutional variables that may affect the quality of these outcomes, including volunteers' language capacity and the intensity of the service placement.  相似文献

This short research note discusses some of the challenges involved when undertaking qualitative research with ‘young offenders’, a neglected area within the methodological literature. By drawing on previous research with ‘young offenders’, the author discusses how the use of traditional face‐to‐face interviews produced a number of research challenges which are specific to the psychosocial, biographical and institutional contexts of this particular population. In attempting to overcome some of these challenges in her current research, the author developed a specific research tool – the assisted questionnaire (AQ) – and the remainder of this article describes how its use with ‘young offenders’ helped to overcome some of the methodological challenges which had earlier been identified.  相似文献

Given negative effects of cohabitation, we examine negative (ambivalence, conflict) and positive (commitment, satisfaction) relationship quality, as explained by perceptions of ease of relational sacrifices and spirituality, for unmarried cohabitors expecting their first child (46 individuals). Controlling for race/ethnicity and education, perceived ease of relational sacrifice was associated with greater satisfaction and lower ambivalence and conflict, whereas spirituality was not associated with any of the relationship quality variables. Examined together, greater ease of relational sacrifice and higher spirituality were associated with greater commitment and satisfaction and lower ambivalence and conflict. Given that many studies of cohabitation focus on demographic factors and that many studies of spirituality focus on married couples, the current study expands knowledge regarding relationship quality for nontraditional couples.  相似文献

A pilot outreach program was designed to reduce social isolation and meet the social service needs of elderly living in the community. In order to meet the social service needs of 72 socially isolated older persons, peer counselors used a problem solving casework approach focused on enhancing self-help skills. Community development efforts and networking techniques were implemented to encourage participants to expand their social interaction networks and develop peer support systems. An evaluation of the pilot program suggests that it was successful in decreasing social isolation and in meeting the social service of those who were served.  相似文献
