Key points

  • Publishing is fixated on the format of the scholarly article, and this is stifling innovation.
  • Content should be presented in a way that adapts dynamically to the reader's needs.
  • A lot of interdisciplinary research is needed to transform reading, writing, and publishing processes.

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

Established in 2014, Usus (Latin for usage), supported by Counting Online Usage of NeTworked Electronic Resources (COUNTER), but editorially independent, is a community-run website designed to provide a space for librarians, consortia, publishers, aggregators, repository managers, and scholars to discuss all aspects of usage, including particular ways that use is measured. In this session, Usus Supervisory Board members provided an introduction to Usus, outlined the purpose of the community-run site, and discussed how librarians may utilize the site to submit ongoing and complex usage issues. In addition, the presenters engaged attendees in discussing specific e-resource usage issues they have encountered as well as report changes and additions in the recently released COUNTER Code of Practice 4.  相似文献

Mooses and colleagues suggest that running economy alone does not explain superior distance running performance in elite Kenyan runners. Whilst we agree with the multi-factorial hypothesis for Kenyan running success, we do not believe that running economy can be overlooked to the extent that it was based on this particular study. Based on the methods used and the range of athletes tested, in this response letter we question whether this study provides any basis for downplaying the influence of running economy or suggesting that other factors compensate for it to enable superior performance.  相似文献

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.  相似文献

Abstract

Motorsport is an under-researched area of socio-historical study. There is particularly limited academic understanding of female involvement in the social world of motorsports. Therefore, this paper focuses on the role of the media in presenting and establishing motorsport for women. In particular, a documentary analysis of articles published by a UK national newspaper group from 1890, and a case study of an all-female UK-based motor-racing championship are used to account for gendered processes that have influenced attitudes and behaviours towards women motor racers. The motor car emerged through technological progress in an overtly masculine-dominated industrial period. Traditional assumptions and biologically deterministic attitudes towards women were used by men to position motoring and motor-racing as a male preserve. Newspaper reporting throughout the 1930s suggests an era of heightened success for women motor racers as a result of gaining access to a key resource in the form of Brooklands motor-racing circuit. Following the Second World War, there was increasing commercialization and professionalization of male-dominated motorsport, as well as renewed marginalization and trivialization of female participants within the newspapers. These processes continue to influence perceptions of women in contemporary motorsport.  相似文献

Benefits of bilateral practice both for the non-dominant and for the dominant body side have been shown in several studies. Thereby, most of the studies included movement tasks of the upper extremity or investigated sports games in which the ability of acting bilaterally is an essential basis for success and, thus, a bilateral practice is reasonable anyway. Individual unilaterally performed sports including movement tasks of the lower extremity are rarely investigated. Therefore, the aim of our study was to test if contralateral transfer due to bilateral practice can be found in an unilaterally performed sport including the lower extremity. We trained and tested 61 adolescent athletes in long jump to compare the jumping performance of the dominant leg after a 12-week practice period between two groups: a bilateral practice group that practiced specific long jump exercises with both the dominant and non-dominant leg and an unilateral practice group that practiced specific long jump exercises only with the dominant leg. Results showed a superior effect of bilateral practice compared to unilateral practice regarding the jumping performance of the dominant leg. The performance increase at post-test and retention-test for the dominant limb was significantly higher for the bilateral practice group (pre-to-post: 5.2%, pre-to-retention: 7.4%) compared to the unilateral practice group (pre-to-post: 3.4%, pre-to-retention: 4.5%). Thus, bilateral practice should be established in the early practice programmes of track and field athletes to improve the performance of the dominant take-off leg.  相似文献

There are established links between education and well-being, and between poverty and education. This article draws on interviews with parents of school-aged children impacted by a policy in the UK commonly referred to as the ‘bedroom tax’. A critical psychology perspective to education is put forward, acknowledging the complex interrelationships between psychological well-being, sociopolitical factors and education.  相似文献

This paper presents a comparative research study as a model for assessing undergraduate education. This evaluation model used Factor Analysis to create scales, tested the reliability of these scales, and used Analysis of Variance to compare the primary institution with five types of comparable institutions. The value of this statistical/methodological evaluation model was shown. Results are based on Class of l998survey responses from 244 graduating seniors at the primary institution and 1481 students at 39peer institutions. Comparative analyses identified business courses, faculty, career preparation and impact on students’ technological skill as strengths and students’ knowledge of arts and foreign languages and campus social life as areas for improvement at the primary institution. Recommendations advocated publicising students’ superior satisfaction with courses, faculty and career preparation; using these results as baseline data for future curriculum evaluation; and continuing efforts to enhance campus social life. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献
