This study examined political journalists’ definitions of public opinion and how these definitions influence the structure of political news stories. After considering prior conceptualizations of public opinion, a scale of two distinct definitions of public opinion was created, consisting of the optimist’s and the pessimist’s definitions. Using a survey of political journalists in the United States, these public opinion definitions were significant predictors of the use of particular sources in political news stories. Importantly, the two definitions had opposite influences on the use of opinion polls, shedding light on the discrepancy in use and perception of poll results in political news.  相似文献

This study investigated the degree to which religious pluralistic language varies as a function of the intergroup salience of a context and religious orientation. Based on a 2 (Religious Salience of Context) × 3 (Religious Salience of Topic) experimental design, participants (N = 239) were instructed to compose an e-mail to an interactional partner based on the randomly assigned condition. Messages were coded for religious pluralistic language, and participants completed measures of religious orientation and evaluations of the conversational partner. Modest effects were found for both intergroup salience of the context and topic as well as religious orientation.  相似文献

There is a growing trend toward a consolidation of services for electronic resources management, A–Z journal listings, full text link resolving, and discovery services under a single service provider. In many cases, the adoption of a discovery service from a provider that is not the same as the libraries’ existing link resolver service means managing multiple knowledgebases. In this session, three librarians gave an overview of their experiences and strategies for maintaining separate link resolving and discovery services in lieu of adopting a full suite of services from a single service provider. Each speaker presented a case study on the advantages and challenges of managing their chosen discovery service: EBSCO Discovery Service, Ex Libris’ Primo and ProQuest’s Summon, in conjunction with the CUFTS/GODOT open source knowledgebase and link resolver service.  相似文献

This study is designed to identify the underlying satisfaction dimensions gained through engagement in target shooting as a serious leisure pastime. The instrument design was based on the Leisure Satisfaction Scale. A total of 5502 useable surveys were collected through the Internet and a website related to target shooting and gun ownership. The results revealed eight dimensions: self-actualization, social interaction, location aesthetic, respite, physical benefit, connection and hedonic pleasure, which supplied the primary satisfiers of engaging in target shooting as a serious leisure activity. The demographic profile and dimensions of satisfaction may serve to dispel commonly held stereotypes of shooting hobbyists and those involved in gun ownership. The findings have important implications for leisure researchers and practitioners, to industry, both leisure and firearm related, and the target shooting community at large. This study adds to the literature of both target shooting and serious leisure.  相似文献

An instrument, Student Survey Questionnaire, assessed the appropriateness of students' social and personal problems for discussion with a counsellor. It was hypothesized that there would be no significant relationship between the social and personal problems of students and the appropriateness of the problems for discussion with a counsellor. It was tested using a 2×5 chi square contingency table of non-admission or admission of problems against five appropriateness levels. The result showed a significant relationship: the more problems the students admit the more they want to discuss them. Most of the students who admitted they have personal and social problems saw these problems as appropriate for discussion with a counsellor.  相似文献

While scholars have increasingly engaged with the (micro)political and emotional experiences of coaches in professional and semi-professional football, little attention has been given to grass-roots coaches’ understandings of these issues. The aim of this paper is to outline one possible research agenda that could contribute to the development of a rich and increasingly nuanced understanding of the everyday realities of being a grass-roots football coach. In particular, we consider (volunteer) coaches’ participation in grass-roots football to be an inherently relational endeavour. Following the presentation of a creative fiction that is based upon our shared experiences of being grass-roots football coaches, we then illustrate how relational thinking might be productively applied to exploring the social, (micro)political and emotional features of grass-roots football coaching.  相似文献

The purpose of this study was to assess the reproducibility of body composition measurements by dual-energy X-ray absorptiometry (DXA) in 12 elite male wheelchair basketball players (age 31 ± 7 years, BMI 21 ± 2 kg/m2 and onset of disability 25 ± 9 years). Two whole body scans were performed on each participant in the supine position on the same day, using Lunar Prodigy Advance DXA (GE Lunar, Madison, WI, USA). Participants dismounted from the scanning table and were repositioned in-between the first and second scan. Whole body coefficient of variation (CV) values for bone mineral content (BMC), fat mass (FM) and soft tissue lean mass (LTM) were all <2.0%. With the exclusion of arm FM (CV = 7.8%), CV values ranged from 0.1 to 3.7% for all total body and segmental measurements of BMC, FM and LTM. The least significant change that can be attributed to the effect of treatment intervention in an individual is 1.0 kg, 1.1 kg, 0.12 kg for FM, LTM, and BMC, respectively. This information can be used to determine meaningful changes in body composition when assessed using the same methods longitudinally. Whilst there may be challenges in the correct positioning of an individual with disability that can introduce greater measurement error, DXA is a highly reproducible technique in the estimation of total and regional body composition of elite wheelchair basketball athletes.  相似文献

The present study used cultivation theory to explore the relationships between celebrity media diet and materialism for a sample of 224 emerging adults. Results indicated main effects between both celebrity magazine consumption and celebrity TV news consumption on materialism. Total celebrity media diet was also significantly related to materialism. Findings suggest that a media diet high in celebrity culture and lifestyle has significant impact on emerging adults’ preoccupation with consumerism, particularly for women. This research contributes to a growing body of literature on the effects of a celebrity-saturated media environment and the cultivation of materialistic attitudes.  相似文献
