Peer effects on youth screen media consumption in Catalonia (Spain)     

Josep-Oriol Escardíbul  Toni Mora  Anna Villarroya 《Journal of Cultural Economics》2013,37(2):185-201

It is well known that young people are major consumers of screen media and that their peers are one of the principal determinants of youth behavior as regards their patterns of consumption and other activities. On the basis of these premises, the purpose of this paper is to analyze the influence of classroom peers on youth screen media consumption. More specifically, it considers the time spent watching TV, playing console games and surfing the Internet. Data are drawn from a single representative survey of secondary school students aged 14–16 in Catalonia (Spain) in 2008. Having accounted for problems of endogeneity, our analysis shows that peer consumption has a positive and statistically significant effect on an individual’s console and Internet use. While the magnitude of this effect is not great in the case of the former use, peer effects are quite marked in that of Internet consumption. Moreover, gender differences are observed when media consumption is examined separately. Thus, peer effects on console use are statistically significant only for boys, while the influence of peers on an individual’s Internet use is higher among boys than it is among girls.  相似文献   

A keynote to the pre‐conference symposium on the international aspects of the white house conference on library and information services

Abstract

Computer science in the United States is hard pressed to show broad utility to help justify billion dollar research programs and the value of educating well over 40,000 bachelor of science and master of science specialists annually in the United States. The Computer Science and Telecommunications Board of the U.S. National Research Council recently has issued a report, “Computing the Future” (Hartmanis &; Lin 1992), which sets a new agenda for computer science. The report recommended that computer scientists broaden their conceptions of the discipline to include computing applications and domains to help understand them. This article argues that many computer science graduates need some skills in analyzing human organizations to help develop appropriate systems requirements, because they are trying to develop high‐performance computing applications that effectively support higher performance human organizations. It is time for academic computer science to embrace organizational analysis (the field of Organizational Informatics) as a key area of research and instruction.  相似文献   

Cortisol Reactivity to Social Stress as a Mediator of Early Adversity on Risk and Adaptive Outcomes     

Elisabeth Conradt  Beau Abar  Barry M. Lester  Linda L. LaGasse  Seetha Shankaran  Henrietta Bada  Charles R. Bauer  Toni M. Whitaker  Jane A. Hammond 《Child development》2014,85(6):2279-2298

Children chronically exposed to stress early in life are at increased risk for maladaptive outcomes, though the physiological mechanisms driving these effects are unknown. Cortisol reactivity was tested as a mediator of the relation between prenatal substance exposure and/or early adversity on adaptive and maladaptive outcomes. Data were drawn from a prospective longitudinal study of prenatal substance exposure (N = 860). Cortisol reactivity was assessed at age 11. Among African Americans, prenatal substance exposure exerted an indirect effect through early adversity and cortisol reactivity to predict externalizing behavior, delinquency, and a positive student–teacher relationship at age 11. Decreased cortisol reactivity was related to maladaptive outcomes, and increased cortisol reactivity predicted better executive functioning and a more positive student–teacher relationship.  相似文献   

Developmental and contextual risks of social physique anxiety among female athletes     

Gay JL  Monsma EV  Torres-McGehee TM 《Research quarterly for exercise and sport》2011,82(2):168-177

In the present study, we examined developmental and contextual factors that may increase the odds of reporting higher social physique anxiety (SPA) among 404 adolescent athletes 11 to 16 years old. Findings showed older, later maturing athletes past peak height velocity and with greater body mass index (BMI) reported higher SPA. Individual aesthetic sport athletes were older at menarche, had lower BMI, and reported higher SPA. The odds of reporting higher SPA were 4.5 times higher (odds ratio = 4.61) for individual aesthetic sport athletes than for nonaesthetic sport athletes. Team aesthetic sport contexts were not implicated in SPA risk. Results are discussed in terms of self-selection away from individual aesthetic sports and the relevance of physical size and puberty in the SPA construct.  相似文献

Active citizenship through sport education     

Toni M. O'Donovan  Ann MacPhail  David Kirk 《Education 3-13》2013,41(2):203-215

Sport education (SE) is an instruction model developed amid concerns about the lack of authentic, legitimate opportunities for young people to experience sport through physical education and was designed to facilitate enhanced links between experiences in physical education and those in the wider world of sport. The paper discusses how one UK primary school delivered key citizenship education learning through the use of SE. The research reported here is based on interviews with teachers and students in Year 6 at one co-education, state-run primary school. The paper highlights the possibilities for teaching citizenship through the medium of sport while recognising the central importance of the creative teaching approach rather than the subject matter of sport in facilitating the development of active citizenship. The possibilities for citizenship education through sport to be celebratory and supportive of real-world discourses are highlighted. As a solution to the overcrowded curriculum in primary schools, SE has been embraced and developed by the teachers in ‘Forest Gate School’.  相似文献   

COIL on Wheels: A Library Professional Development Roadshow     

Toni Hoberecht  Emily Brown 《Medical reference services quarterly》2013,32(3):286-293

Professional development for instruction librarians is in danger of coming to a standstill in difficult economic times. COIL on Wheels is a professional development roadshow developed by the Community of Oklahoma Instruction Librarians to allow librarians with budget and staffing issues to benefit from peer training. By matching member librarian interests with institutional needs, librarians can visit institutions in their geographic area to provide their colleagues with low-cost or free training. This article discusses the origins of and rationale for this program and describes a successful implementation of this traveling professional development project.  相似文献   

We Ning-ed a Virtual Pre-Workshop: Now What?     

Amanda Lemon  Toni Hoberecht  Emily Brown 《The Reference Librarian》2013,54(3):208-217

In 2009, a group of instruction-minded librarians in Oklahoma added unconference-like elements to their usual workshop structure and agenda to make their workshop more participatory and attendee-driven. The result was a virtual pre-workshop hosted on a Ning social networking site. The virtual pre-workshop enhanced the actual physical workshop in several ways. The group's new challenge: where to host its new pre-workshop format without Ning and how to gear the new format to be more mobile friendly while not excluding non-mobile interested workshop participants.  相似文献
