Analysis of Open Access Landscape 总被引:4,自引:0,他引:4
Helen Doyle Andy Gass Debra Lappin Rebecca Kennison 《图书情报工作》2005,49(12):6-13
This paper is created by bounding 5 editorials of Public Library of Science (PLoS) which have written on various aspects of open access. It covers wide range topics of important open access issues, such as from paying for open access to copyright to open access as a public issue, which may be more or less of interest of our audience. 相似文献

This study investigated the effects of two separate doses of sodium bicarbonate (NaHCO3) on 4 km time trial (TT) cycling performance and post-exercise acid base balance recovery in hypoxia. Fourteen club-level cyclists completed four cycling TT’s, followed by a 40 min passive recovery in normobaric hypoxic conditions (FiO2 = 14.5%) following one of either: two doses of NaHCO3 (0.2 g.kg?1 BM; SBC2, or 0.3 g.kg?1 BM; SBC3), a taste-matched placebo (0.07 g.kg?1 BM sodium chloride; PLA), or a control trial in a double-blind, randomized, repeated-measures and crossover design study. Compared to PLA, TT performance was improved following SBC2 (p = 0.04, g = 0.16, very likely beneficial), but was improved to a greater extent following SBC3 (p = 0.01, g = 0.24, very likely beneficial). Furthermore, a likely benefit of ingesting SBC3 over SBC2 was observed (p = 0.13, g = 0.10), although there was a large inter-individual variation. Both SBC treatments achieved full recovery within 40 min, which was not observed in either PLA or CON following the TT. In conclusion, NaHCO3 improves 4 km TT performance and acid base balance recovery in acute moderate hypoxic conditions, however the optimal dose warrants an individual approach. 相似文献

Purpose: The purpose of this investigation was to examine the effects of a submaximal running warm-up on running performance in male endurance athletes (n = 16, Mage = 21 ± 2 years, MVO2max = 69.3 ± 5.1 mL/kg/min). Method: Endurance performance was determined by a 30-min distance trial after control and submaximal running warm-up conditions in a randomized crossover fashion. The warm-up began with 5 min of quiet sitting, followed by 6 min of submaximal running split into 2-min intervals at speeds corresponding to 45%, 55%, and 65% maximal oxygen consumption (VO2max). A 2-min walk at 3.2 km/hr concluded the 13-min warm-up protocol. For the control condition, participants sat quietly for 13 min. VO2 and heart rate (HR) were determined at Minutes 0, 5, and 13 of the pre-exercise protocol in each condition. Results: At the end of 13 min prior to the distance trial, mean VO2 (warm-up = 14.1 ± 2.2 mL/kg/min vs. control = 5.5 ± 1.7 mL/kg/min) and mean HR (warm-up = 105 ± 11 bpm vs. control = 67 ± 11 bpm) were statistically greater (p < .001) in the warm-up condition compared with the control condition. The distance run did not statistically differ (p = .37) between the warm-up (7.8 ± 0.5 km) and control (7.7 ± 0.6 km) conditions; however, effect size calculation revealed a small effect (d = 0.2) in favor of the warm-up condition. Thus, the warm-up employed may have important and practical implications to determine placing among high-level athletes in close races. Conclusions: These findings suggest a submaximal running warm-up may have a small but critical effect on a 30-min distance trial in competitive endurance athletes. Further, the warm-up elicited increases in physiological variables VO2 and HR prior to performance; thus, a submaximal specific warm-up should warrant consideration. 相似文献

Assessing cultural values: developing an attitudinal scale 总被引:1,自引:0,他引:1
Effective measurement of cultural value is often elusive because of its multidimensional nature. It is also influenced by
sociodemographic characteristics (manifest variables) and attitudinal characteristics (latent variables) of populations. While
the former is easily available to researchers, the latter has not been fully studied. This paper suggests the use of a cultural
worldview scale that was developed to measure cultural attitudes of people, using factor and cluster analysis. Four factors
comprise the scale: cultural linkages, recognition of cultural values, cultural loss and preservation of traditions and customs.
Some advantages of using this scale are demonstrated, and relationships with sociodemographic variables are investigated.
Managerial and policy implications are discussed.

Few accounts of drama projects and their value for pupils with moderate learning difficulties and other types of special educational needs have appeared in the journal. Andy Kempe, lecturer in drama in education, Reading University, helps to fill this gap by giving an evaluative account of a TVEI-funded drama project which he coordinated. 相似文献
