The purpose of this study was to investigate the accuracy of fat-free mass (FFM) estimates from two-compartment (2C) models including air displacement plethysmography (ADP), ultrasound (US), near-infrared interactance (NIR), and the Jackson and Pollock skinfold equation (SKF) against a criterion four-compartment (4C) model in elite male rowers. METHODS: Twenty-three elite-level male rowers (mean± SD; age 24.6 ± 2.2 years; stature: 191.4 ± 7.2 cm; mass: 87.2 ± 11.2 kg) participated in this investigation. All body composition assessments were performed on the same day in random order, except for hydrostatic weighing (HW), which was measured last. FFM was evaluated using a 4C model, which included total body water from bioimpedance spectroscopy, body volume from HW, and total body bone mineral via dual-energy X-ray absorptiometry. The major findings of the study were that the 2C models evaluated overestimated FFM and should be considered with caution for the assessment of FFM in elite male rowers. Future studies should use multiple-compartment models, with measurement of TBW and bone mineral content, for the estimation of FFM. 相似文献

The British Journal of Educational Technology (BJET) uses a novel system for obtaining referees by e‐mailing the abstracts of submissions to a panel of over 250 referees and allowing these individuals to choose which papers they would like to review. An analysis of 13 experienced referees showed that, of 473 reviews assessed, these referees were slightly more lenient than the editor and that electronic records provide useful data that can be mined in interesting ways. 相似文献

Current findings from research on structured abstracts. 总被引:5,自引:0,他引:5
James Hartley 《Journal of the Medical Library Association》2004,92(3):368-371
BACKGROUND: Structured abstracts were introduced into medical research journals in the mid 1980s. Since then they have been widely used in this and other contexts. AIM: The aim of this paper is to summarize the main findings from research on structured abstracts and to discuss the limitations of some aspects of this research. METHOD: A narrative literature review of all of the relevant papers known to the author was conducted. RESULTS: Structured abstracts are typically longer than traditional ones, but they are also judged to be more informative and accessible. Authors and readers also judge them to be more useful than traditional abstracts. However, not all studies use "real-life" published examples from different authors in their work, and more work needs to be done in some cases. CONCLUSIONS: The findings generally support the notion that structured abstracts can be profitably introduced into research journals. Some arguments for this, however, have more research support than others. 相似文献

This paper is in the tradition of social analysis aimed at creatingframeworks to join mass media and public opinion processes (e.g.Clarke and Evans, 1983; Gamson, 1975; Gitlin, 1980; Hall, 1977;Iyengar and Kinder, 1987; Lang and Lang, 1968, 1983; Lippman,1922; Mollotch and Lester, 1974; Noelle-Neuman, 1974; Paletzand Entman, 1981; Shaw and McCombs, 1977; Turner and Paz, 1986).After a brief review of media system dependency (MSD) theory,we illustrate how it may apply to public opinion processes thatentail contested issue value-frames (Ball-Rokeachand Rokeach, 1987). In such cases, the media system is directlyimplicated in the negotiation of legitimacy of opposing positionson an issue. Our illustrative case is the abortion issue asit has been played out in the United States over recent decades(Luker, 1984). We focus upon the respective capacities of pro-and anti-abortion movements to control the value-frame of mediacoverage of the issue (Guthrie, 1989). A value-frame may beconceived as ... the main substantive theme of a moralityplay (Ball-Rokeach and Tallman, 1979) wherein the distinctionbetween good and bad hangs in thebalance; in this case, between positions on abortion. We suggestthat change in the value-frame of media coverage and publicdiscourse may be understood, at least in part, as an outcomeof change in contestants' MSD relations. 相似文献

More students with disabilities are accessing the tertiary sector with many disabilities not easily observed (or hidden), because there are no physical indicators. These “hidden” disabilities affect a variety of cognitive processes and may be developmental or acquired. To ensure students with hidden disabilities can enrol, engage in and benefit from tertiary education, universities generally provide a range of supports. Typically these supports and any reasonable adjustments are negotiated with students taking into account a number of factors including, where available, any supporting documentation that they might be able to provide. This case study reports efforts within one large Australian university to support higher education students with hidden disabilities on campus. Perceptions on the use of and barriers to support available were collected from seven undergraduate students who self-identified as having hidden disabilities and from eight support staff. Results indicated that students found their informal networks to be their most effective supports, closely followed by clear, caring and flexible lecturers and tutors. There were mixed positive and negative perceptions reported on the universal and disability-specific supports available. Implications and future research directions are discussed. 相似文献
