The above authors, all from the Department of Adult Education, Nottingham University, have developed computerbased education and training for disabled adults in six centres in the East Midlands. In its service to the students – if not in its resourcing – it is a model for others to follow. 相似文献

We investigated the effect of an acute creatine loading (25 g per day for 4 days) and longer-term creatine supplementation (5 g of creatine or 5 g of placebo per day for 2 months) on the performance of 22 elite swimmers during maximal interval sessions. After the acute creatine loading, the mean of the average interval swim times for all swimmers (n = 22) improved (44.3+/-16.5 s before vs. 43.7+/-16.3 s after supplementation; P<0.01). Three of the 22 swimmers did not respond positively to supplementation. After 2 months of longer-term creatine supplementation or placebo, neither group showed a significant change in swimming performance (38.7+/-13.5 s before vs. 38.7+/-14.1 s after for the creatine group; 48.7+/-18.0 s before vs. 48.7+/-18.1 s after for the placebo group). We conclude that, in elite swimmers, 4 days of acute creatine loading improves swimming performance significantly when assessed by maximal interval sessions. However, longer-term supplementation for 2 months (5 g of creatine per day) did not benefit significantly the creatine group compared with the placebo group. 相似文献

This paper describes a pilot antenatal education program intended to better prepare couples for the early weeks of lifestyle changes and parenting. Eight weeks after birth, data were collected by questionnaire from 19 couples who participated in a pilot program and from 14 couples who were enrolled in a routine hospital program. Women in the pilot program were significantly more satisfied with their experience of parenthood. Facilitated gender-specific discussion groups formed a key strategy in the pilot program. 相似文献

Growth and maturation impact the selection, development and progression of youth athletes. Individual differences in the growth and maturity may afford a performance advantage, clouding coaches and practitioners’ perceptions regarding current ability and future potential. This may result in the exclusion of talented, yet less physically gifted athletes. Participants were 91 male (n = 47) and female (n = 44) elite British Junior tennis players, 8–17 years of age (12.5 ± 1.9 years). Height and body mass were measured and compared to growth charts; hand-wrist radiographs were taken. Skeletal age (SA) was estimated with the Fels method and contrasted to chronological age (CA). Mean height and body mass of individual players ranged between the 50th and 90th centiles for age and sex. Females were advanced in SA relative to CA (0.3–0.89 years.) from 8 years. Males were average to delayed in maturation from 8 to 12 years, but advanced in SA from 14 to 16 years (0.75–1.23 years). Individual differences in growth and maturation appear to contribute towards the selection of elite junior tennis players, with a bias towards males and females who are advanced in maturation and comparatively tall and heavy for their age. This has important implications for talent identification and development. 相似文献

Teacher feedback is critically related to student learning. This study sought to determine the relationships between distance education (DE) student level of self-regulated learning (SRL) and their preference for audio-recorded vs. written feedback from tutors. DE students (n = 102) enrolled in a first-year university course completed an online questionnaire that assessed eight dimensions of SRL as well as a personal evaluation of written vs. audio-recorded tutor feedback that was provided during the academic study period. In general, the participating DE students expressed preference for written over audio-recorded feedback. However, complex patterns of relationships emerged between dimensions of SRL and evaluation of written vs. audio-recorded feedback. For example, DE students who were most likely to listen to audio-recorded feedback appreciated peer interaction and personal challenges more than students who preferred written feedback. In DE learning environments, a variety of feedback formats may best meet the needs of all students, although exposure to various technologies may facilitate SRL. 相似文献

To identify pathways to lower environmental impacts, this research examined the motivation and antecedents of motivation (autonomy, relatedness, competence), of environmentally active people. Previous research suggests that people with more self-determined motivation for pro-environmental behavior (PEB) should carry out more PEBs, and have lower environmental impacts, than people whose motivation is more externally regulated. Path analysis in Sample 1 (N = 261) confirmed that self-determined motivation was positively related to both easy and difficult PEB. The more participants judged that their needs for autonomy and relatedness were met in relation to performing PEB, the more self-determined their motivation. Higher perceived relatedness was also directly related to reporting more engagement in difficult PEB. Perceived competence was not related to self-determined motivation or PEB. The pattern of results was largely supported when re-tested with a sample (N = 320) who completed a ‘carbon footprint’ measure of environmental impact as well as the questionnaire completed by Sample 1. In this sample, autonomy, relatedness, and competence were related to self-determined motivation. The research is the first to our knowledge to examine and find a relationship between higher self-determined motivation and lower self-reported environmental impact. These findings point to new approaches to increasing PEB. 相似文献

Matrix A with characteristic polynomial Q(z) is defined positive or negative Hurwitz according to whether Q(z) or Q(-z) is a Hurwitz polynomial. Leading principle sections of the Tikhonova growth matrix have associated characteristic polynomials Pn(-z) which satisfy the recursionThat the Tikhonova growth matrix is negative Hurwitz is established through applying the Wall-Stieltjes theory of continued fraction expansions to show the Pn(-z) are Hurwitz polynomials. The Kayeya-Enestrom theorem and a procedure for refinement of the Gerschgorin estimate are used to obtain analytical bounds on spectral radii for the Tikhonova model, which provides estimates of maximal growth rates. The theory allows generalization to more complicated growth models. 相似文献

Estimating changes in hydration status from changes in body mass: considerations regarding metabolic water and glycogen storage 总被引:1,自引:0,他引:1
The potential for imprecision in the estimation of hydration status from changes in body mass has been outlined previously but the equations derived from these derivations appear inconsistent. Reconciliation of body mass loss in terms of sweat loss and effective body water loss is possible from specific equation sets provided that gains and losses of both body mass and water used in the derivation of sweat loss and to derive effective body water loss are in inclusive equation sets. This is obligatory so that mass and water changes as quantifiable determinants are consistent with both internal processes and external gains and losses. Thus, body mass loss, substrate oxidation, metabolic water, and all the terms used in simultaneous equation sets have to be reconciled not only as identical variables but mathematically balance exactly. The revised equation for effective body water loss given here is different from that originally proposed. Metabolic water is part of body mass loss corrected for substrate oxidation, fluid ingestion, and respiratory water to derive sweat loss and it may not be justified to also include water associated with glycogen as releasable bound water. Accordingly, our calculated effective body water loss is substantially a greater loss than originally supposed but clearly still less than the simple balance between mass loss and fluid ingested. 相似文献
