This investigation identifies demographic, media, and social correlates of verbally aggressive communication in adolescence. Mail surveys were completed and returned by 2,300 adolescents between the ages of 13 and 15. These adolescents were asked about the prevalence of verbal and physical aggression, the context in which it occurred, demographics, and the interpersonal and media influences in their lives. The results indicate that verbal aggression is widespread, that committing and experiencing verbal aggression is largely reciprocal, that there is a strong relationship between committing verbal and physical aggression, and that peer social influence and listening to violently oriented music are mildly related to verbal aggression in adolescents. These findings suggest more resources should be allocated to teaching adolescents to understand and control verbal aggression. Further, they provide important answers to many prevention and intervention programmatic questions, including context, content, and targeting concerns. Since the negative consequences of verbal aggression are severe and long lasting, decreasing this destructive communication behavior should significantly improve the lives of many adolescents. These and other practical implications are expanded upon and discussed. 相似文献

Cyberbullying victimization research on individual and familial correlates is scarce in Spain. By building upon previous studies, this research examines the role of Internet usage and parental mediation in online victimization. Spanish children from rural public schools (10–12 years; n?=?1068) completed a self-report questionnaire which measured being cyberbullied, Internet use and parental mediation strategies. Logistic regression analyses examined the association among cyberbullying victimization, online activities, intensity and purposes of online communication, and restricting, evaluating and co-using parental mediation. The results show that Internet use, specifically online communication, increases the likelihood of cyberbullying victimization. Conversely, monitoring software installed on the computer, joint creation of rules regarding the time spent online and personal information shared help lessen the likelihood of online victimization. The results are examined in the light of previous research, while implications for practice and future research are considered. 相似文献

Continuous improvement initiatives are of increasing importance due to the high operating risks of engineering, procurement, and construction management (EPCM) firms in the oil and gas sector ($188 billion worth of oil and gas projects in 2008). This article describes a continuous improvement framework that translates performance problems into an action plan and helps to prevent their recurrence. 相似文献

Two basic approaches have been used by the literature focusing on the return to holding artistic works: the hedonic price model and the repeat-sales model. This paper provides a procedure for jointly estimating the two models in a way that take advantages of the unique information contained in each. A semiannual price index for Picasso prints is estimated by using a model derived from the basic framework of the hybrid models. The empirical results suggest that the hybrid model provides the most precisely estimated price index by reducing the level of price volatility.JEL Classification: C5, Z1p 相似文献

Conclusion As culture is at the heart of meaning making, it warrants exacting attention in the systemic design process. As Gustafson
& Powell (1991) point out, too often models are not tested for validity and reliability. It is for this reason that we emphasize
that research must critically evaluate this expanded ADDIE model.
As technology enables us to increase our interaction with the peoples of the world, we are enriched by the incessant shifts
in our own cultural paradigms. Attention to this cultural dynamism and incessant interplay leads to both improved designs
and improved designers. As instructional designers, we must be able to critically analyze our learner’s cultures and allow
it to strengthen the instructional design process. In this way we address our ethical commitment to creating culturally sensitive
products.
His research interests include culture, identity development, and meaning making in technology rich environments.
His research interests are in the areas of Educational Gerontology, Instructional Design, and the Digital Divide.

This article discusses the application of the peer review process as a pedagogical instrument for the promotion of written expression, collaborative work, critical thinking, and professional responsibility among Informatics and Engineering majors. The approach is introduced with a motivation, followed by a discussion about common principles of current learning paradigms and the peer review process. This work is being conducted in Brazil, where we intend to promote a learning paradigm shift through the application of peer review in education. A framework for this application is outlined, together with an account of results from experiences and a discussion about the skills that this approach exercises, especially with regard to widely accepted curricula and codes of ethics and professional conduct. Further research and development efforts are conjectured. 相似文献

Abstract Eighty-two male college students were divided into three equal-size groups for the purpose of testing the transfer effects between motor skills judged similar in perceptual components but different in motor components. Criterion measures of gross movement ability and static balance were analyzed and practice tasks similar to these criterion measures in perceptual components but different in motor components were developed. All subjects were pretested on the criterion measures, after which groups 1 and 2 practiced 3 min. per day for 28 days on the practice tasks while group 3 performed unrelated isometric exercises. On the post-test, the experimental groups were found to be significantly superior to the control group on gross movement accuracy and static balance. It was implied that the transfer resulted from the similarity in perceptual components of the two motor skills, and that perceptual abilities were subject to improvement through practice. 相似文献

The effects of initial conditions on the flight of an American football kicked in an end-over-end manner were investigated using a dynamic simulation employing the quaternion method. The effects of initial tilt and spin about the longitudinal axis of the ball were considered. For the most accurate kick, our simulations show that the ball should be vertical leaving the kicker’s foot, and have no angular velocity about the longitudinal axis of the ball. A case study was performed for which experimental data were available, showing the trends of the flight of the ball captured in our simulations in actual game situations. 相似文献

Public health perspectives on violence-related injuries have become increasingly important over the past two decades, yet they are rarely mentioned in criminal justice educational texts or articles. Here we provide a brief overview of the public health approach to the prevention of violence and related injuries and compare it to an approach to crime prevention commonly associated with the criminal justice approach: deterrence. The prevention of sexual assault on college and university campuses is used as an illustration of the two approaches. Finally, given the similarities between the manner in which these two multi-disciplinary fields approach violence prevention, we explore how and why criminal justice educators might want to teach a bridge between public health and criminal justice. 相似文献
