Communicating Prevention: The Effects of the keepin' it REAL Classroom Videotapes and Televised PSAs on Middle-School Students' Substance Use

This study sought to determine if exposure to two communication-oriented activities, videotapes and public service announcements, accounts for changes in substance use among adolescents participating in the Drug Resistance Strategies Project's keepin' it REAL adolescent substance use prevention curriculum. Middle-school students (4,734, 72% Latino) responded to questionnaires related to these analyses. An analysis of covariance (ANCOVA) model was fit separately to six substance use outcomes. The results suggested that intervention students who saw four or five videos engaged in less substance use in the past month than did students who saw fewer videos. Having seen the PSAs one or more times did not predict the reported change in substance use.     

Automated Classification to Improve the Efficiency of Weeding Library Collections

Previous studies have shown that weeding a library collection benefits patrons and increases circulation rates. However, the time required to review the collection and make weeding decisions presents a formidable obstacle. This study empirically evaluated methods for automatically classifying weeding candidates. A data set containing 80,346 items from a large-scale weeding project running from 2011 to 2014 at Wesleyan University was used to train six machine learning classifiers to predict a weeding decision of either ‘Keep’ or ‘Weed’ for each candidate. The study found statistically significant agreement (p?=?0.001) between classifier predictions and librarian judgments for all classifier types. The naive Bayes and linear support vector machine classifiers had the highest recall (fraction of items weeded by librarians that were identified by the algorithm), while the k-nearest-neighbor classifier had the highest precision (fraction of recommended candidates that librarians had chosen to weed). The variables found to be most relevant were: librarian and faculty votes for retention, item age, and the presence of copies in other libraries.     

Exploring athletes’ perceptions of coach stress in elite sport environments

The present study aimed to extend research that has focused on the identification of stressors associated with coaching practice by systematically evaluating how such stressors effect athletes, and more broadly, the coach–athlete relationship. A total of 13 professional- and national-level athletes were interviewed to address the three study aims: how they detect when a coach is encountering stressors, how coach experiences of stress effects them as an athlete, and how effective the coach is when experiencing stress. Following content analysis, the data suggested athletes were able to detect when a coach was experiencing stress and this was typically via a variety of verbal and behavioural cues. Despite some positive effects of the coach experiencing stress, the majority were negative and varied across a range of personal influences on the athlete, and effects on the general coaching environment. It was also the broad view of the athletes that coaches were less effective when stressed, and this was reflected in performance expectations, perceptions of competence, and lack of awareness. The findings are discussed in relation to the existing theory and with reference to their implications for applied practice, future research, and development of the coach–athlete relationship.     

Examining coaches’ perceptions of how their stress influences the coach–athlete relationship

This study extends recent coach stress research by evaluating how coaches perceive their stress experiences to affect athletes, and the broader coach–athlete relationship. A total of 12 coaches working across a range of team sports at the elite level took part in semi-structured interviews to investigate the 3 study aims: how they perceive athletes to detect signals of coach stress; how they perceive their stress experiences to affect athletes; and, how effective they perceive themselves to be when experiencing stress. Following content analysis, data suggested that coaches perceived athletes able to detect when they were experiencing stress typically via communication, behavioural, and stylistic cues. Although coaches perceived their stress to have some positive effects on athletes, the overwhelming effects were negative and affected “performance and development”, “psychological and emotional”, and “behavioural and interaction” factors. Coaches also perceived themselves to be less effective when stressed, and this was reflected in their perceptions of competence, self-awareness, and coaching quality. An impactful finding is that coaches are aware of how a range of stress responses are expressed by themselves, and to how they affect athletes, and their coaching quality. Altogether, findings support the emerging view that coach stress affects their own, and athlete performance.     

Marginalia in the digital age: Are digital reading devices meeting the needs of today's readers?

For centuries, readers have added marginal commentary to books for a variety of personal and public purposes. Historians have mined the marginalia of important historical figures to observe their sometimes raw, immediate responses to texts. Now, reading and annotation practices are changing with the migration of content to electronic books. A survey of reader attitudes and behavior related to marginalia for print and electronic books reveals that the majority of readers write in their books and want e-readers to support this feature. However, many readers report that annotating electronic books is too difficult, time-consuming, or awkward with current technology. In addition, the way readers annotate books depends on whether they are reading for pleasure or for work or education. These findings can guide the development of future devices to better satisfy reader needs.     

如何阅读3500万个博客?

“科学技术是第一生产力”,伟人不愧是伟人,论断一针见血,不服不行。传媒业越来越感受到科技的力量。这力量,对不同的媒体而言,有些是“压力”,有些是“动力”。科技在拉大差距。在科技力量的作用下,不同类的媒体呈现出不同的发展态势和前景,同类媒体之间的发展分化也在加剧。科技又在消除差距。体现在两个方面:一是国内国外的新闻媒体越来越多地面对越来越多的相同或相似的问题,这背后很重要的因素就是科技的作用;二是科技的发展,无形中降低了很多“门槛”,给市场参与者以更多公平竞争的机会,不管是老媒体还是新媒体,不管是大媒体还是小媒体,都可以借助科技而胜出。如果说过去传媒业的竞争、发展主要考虑“传媒—读者—市场”的关系,今天,今后,则要把“科技”加进来。因为,过去,科技基本上是传媒的“家务事”,其力量基本上体现在采编、印刷等设备更新上,属“辅助性”的力量;现在则不然了,它成了一种“决定性”的力量——不仅对媒体自身,而且对读者和市场。     

Counselor Education and Title IX: Current Perceptions and Questions

This national survey of counselor educator perceptions of the Title IX requirement to report student disclosures of gender‐based discrimination revealed the need for greater clarity about faculty strategies for serving counseling program students while upholding the federal law. The authors describe the recent expansion of the requirements and provide a suggested statement for course syllabi.     

The 2008 Presidential Campaign: Political Cynicism in the Age of Facebook,MySpace, and YouTube

Considerable research over the years has been devoted to ascertaining the impact of media use on political cynicism. The impact of the Internet has been difficult to assess because it is not a single monolithic medium. For example, the 2008 presidential campaign was the first presidential campaign in which popular social networking sites such as Facebook, MySpace, and YouTube were widely available to voters. Therefore, the campaign offered the first opportunity to explore the influence of these social media on political cynicism. In this study, we examined whether the use of such social media influenced political cynicism. We also considered the influence of user background characteristics (e.g., self-efficacy, locus of control, political orientation, demographics, and influence of family and friends), motives for using social media for political information, and users’ elaboration on political content. Several individual differences were stronger predictors of political cynicism than was social media use. In fact, social networking use was a negative predictor of political cynicism. Results supported uses and gratifications’ notions that the influence of social media on political cynicism is more attributable to user background and media-use differences than to sheer use of these popular sites.
