ABSTRACT— Compared to adolescents with low exposure to smoking in movies, those with high exposure are about three times as likely to try smoking or become smokers. We have observed this effect in nationally representative samples using cross-sectional and longitudinal designs. This effect remains statistically significant after controlling for numerous other traditional risk factors, such as personality, parenting style, and sociodemographics. Indeed, the movie-smoking exposure effect on adolescent smoking initiation is greatest among those traditionally considered at lower risk for smoking, such as those low in sensation seeking and those whose parents do not smoke. In this article, we consider possible moderators and mediators of this important media effect as well as health-policy implications. The take-home message is that eliminating smoking in movies may prevent a substantial number of adolescents from smoking. 相似文献

Preschool-aged children (M = 42.44 months-old, SD = 8.02) participated in a short-term longitudinal study investigating the effect of educational media exposure on social development (i.e., aggression and prosocial behavior) using multiple informants and methods. As predicted, educational media exposure significantly predicted increases in both observed and teacher reported relational aggression across time. Follow-up analyses showed that educational media exposure also significantly predicted increases in parent reported relational aggression across more than a two year period. Results replicate and extend prior research that has demonstrated links between educational media exposure and relational aggression, but not physical aggression, during early childhood. 相似文献

As social media becomes increasingly popular, human subjects researchers are able to use these platforms to locate, track, and communicate with study participants, thereby increasing participant retention and the generalizability and validity of research. The use of social media; however, raises novel ethical and regulatory issues that have received limited attention in the literature and federal regulations. We review research ethics and regulations and outline the implications for maintaining participant privacy, respecting participant autonomy, and promoting researcher transparency when using social media to locate and track participants. We offer a rubric that can be used in future studies to determine ethical and regulation-consistent use of social media platforms and illustrate the rubric using our study team’s experience with Facebook. We also offer recommendations for both researchers and institutional review boards that emphasize the importance of well-described procedures for social media use as part of informed consent. 相似文献

This article examines some of the story conventions of network television news to explain the ways in which healthcare interest groups develop and maintain their presence in this medium—a process that has significant implications for public understanding of healthcare issues, and therefore to bioethics. The article is divided into three sections. The first section focuses on three major normative conventions of television news: adherence to a simple narrative structure, the balance ethic, and avoidance of the “think-piece” and outlines the basic strategies available to interest groups for exploiting these normative conventions. Section two introduces three case studies of organizations and individuals who have run high-profile media campaigns. Section three explores the implications for bioethics of the observations made in this article. 相似文献

For women, hijab is a prominent and oftentimes controversial physical marker of their social identity as Muslims. This study explores the perceptions of Muslim women living in Houston regarding the hijab and how these perceptions were partially shaped by media portrayals of Muslim women overseas after the September 11th tragedy. The effects of these perceptions on women's decisions to wear the hijab after September 11th were also examined. Using a convenience sample of 67 women, semi‐structured interviews were conducted. Results suggest that American Muslim women were more likely to talk about hijab in terms of identity than immigrant Muslim women, and to believe that by wearing hijab they could help portray a more positive image of Muslims in the United States. 相似文献

近年来,男性身体意象失调越来越普遍,大众媒体被认为是一种重要的影响因素。大量研究证实了媒体对男性身体意象的消极影响,主要表现在对身体意象的认知、情绪情感和行为调控等方面。研究者基于社会文化理论提出三重影响模型(Thompson,Heinberg,Altabe,Tantleff-Dunn,1999),用以解释媒体影响男性身体意象的作用机制。该模型假设社会文化因素,即家庭、同伴、媒体是身体意象失调的三个最初影响源;外貌比较和"瘦理想"或"肌肉理想"内化是社会文化和身体意象失调之间的中介变量。未来研究应关注被试群体的多样化,将实验室研究和纵向研究相结合,并考虑其他变量的影响作用,对三重影响模型进行丰富和拓展,同时运用脑科学技术探究其神经机制。此外,还应从干预的角度展开研究。 相似文献

Internalization of societal standards of physical attractiveness (i.e., internalization of the thin ideal for women and internalization of the mesomorphic ideal for men) is a widely studied and robust risk factor for body dissatisfaction and maladaptive body change behaviors. Substantial empirical research supports internalization as both a mediator and a moderator of the relation between societal influences and body dissatisfaction. In this paper, a primer on mediation and moderation is followed by a review of literature and discussion of the extent to which internalization can theoretically fulfill the roles of both mediation and moderation. The literature review revealed a stark contrast in research design (experimental versus non-experimental design) when alternate conceptualizations of internalization are adopted. A meta-theoretical, moderated mediation model is presented. This model integrates previous research and can inform future empirical and clinical endeavors. 相似文献

This article discusses the reasons for the religious reactions to the Harry Potter novels, arguing that the books contribute to, and reflect, the reconfiguration of religion in contemporary society. The article analyses the media qualities of fantasy literature and the specific representation of magic in the novels and argues that these aspects form an important part of the reasons for the religious reactions. Fantasy literature and other popular culture that represents and mediates religious expressions and phenomena actively contribute to the reconfiguration of, and communication about, religion in contemporary society and are thus of consequence for what we understand ‘religion’ to be in the study of religions. 相似文献

Previous research indicates a significant association between social media use and psychological adjustment. The present study investigated whether religiosity/spirituality mediates the relationship between social media intrusion and psychological adjustment. Participants completed a demographic questionnaire, Religious Commitment Inventory-10, Spirituality Index of Well-Being, the DASS-21 Scales, and the Facebook Intrusion Questionnaire, which was altered slightly to include all types of social media. Results revealed that social media intrusion was significantly positively associated with depression, anxiety, and stress, and negatively correlated with spiritual well-being and the self-efficacy component of spiritual well-being. Furthermore, the self-efficacy dimension of spiritual well-being partially mediated the association between social media intrusion and psychological stress. From these results, it may be inferred that higher social media intrusion may have the ability to decrease specific aspects of spirituality, which may, in turn, negatively impact psychological adjustment. Limitations and future directions are discussed. 相似文献

Two apparently contradictory ideas are closely linked in Israeli political discourse: Israel is powerful and independent and Israel is vulnerable and dependent. This study used content analysis and focus groups, as well as existing survey data analyzed by others, to explore how this paradox has been reflected in newspapers and conversations during six different time periods from 1948 to 1996. The goal was not to explain the paradox but to examine its consequences for Israeli perceptions of U.S. policy in the Middle East—and, in the process, to explore Israeli self-images. The nature of U.S. strategic interests was originally treated as problematic and in need of political discussion, but in the past 25 years these interests have become taken for granted. Surprisingly, even after the end of the Cold War, a critical discourse moment in which a reexamination of U.S. interests in the Middle East would seem inevitable, the U.S. role remains taken for granted and largely unexamined. The strong/vulnerable paradox explains this absence of discussion: Examining U.S. interests too closely upsets the delicate balance that keeps the sense of vulnerability in check. 相似文献
