“FRIENDS for Life” is a cognitive behavioural therapy (CBT) programme which aims to reduce anxiety and promote resilience among children. This study evaluated the “FRIENDS for Life” (FRIENDS) programme used as an intervention for seven children between the ages of 10 and 11 presenting with high functioning autism spectrum disorder (HFA) who attend mainstream schooling. The study adopts a mixed methodology, explanatory research design, which included pre- and post-quantitative anxiety scales, parental interviews completed post-intervention, narrative observation of FRIENDS sessions and a post-intervention children’s evaluation questionnaire. Quantitative findings from this study suggest that participation in the “FRIENDS” programme does not reduce anxiety levels to promote resilience. Such results are discussed with regard to the utility of using standardised self-report measures among children with HFA. Despite this, qualitative information indicates that “FRIENDS” can be made accessible for children with HFA. Recommendations and implications for future research and FRIENDS implementations are outlined. 相似文献

A new method of surface modification is described for enabling the in situ formation of homogenous porous polymer monoliths (PPMs) within poly(dimethylsiloxane) (PDMS) microfluidic channels that uses 365 nm UV illumination for polymerization. Porous polymer monolith formation in PDMS can be challenging because PDMS readily absorbs the monomers and solvents, changing the final monolith morphology, and because PDMS absorbs oxygen, which inhibits free-radical polymerization. The new approach is based on sequentially absorbing a non-hydrogen-abstracting photoinitiator and the monomers methyl methacrylate and ethylene diacrylate within the walls of the microchannel, and then polymerizing the surface treatment polymer within the PDMS, entangled with it but not covalently bound. Four different monolith compositions were tested, all of which yielded monoliths that were securely anchored and could withstand pressures exceeding the bonding strength of PDMS (40 psi) without dislodging. One was a recipe that was optimized to give a larger average pore size, required for low back pressure. This monolith was used to concentrate and subsequently mechanical lyse B lymphocytes. 相似文献

The aim of this study was to assess the effects of variations in the volume and intensity of resistance training in highly skilled athletes on neural adaptive mechanisms: the maximality and pattern of neural drive. The maximality of muscle activation was measured using a high-resolution sample and hold amplifier to record interpolated twitches. The pattern of neural drive was measured by analysing isometric torque-time curves and electromyographic (EMG) characteristics during the performance of rapid isometric contractions at maximal effort. The volume and intensity of training were varied at 4-weekly intervals to systematically emphasize the development of strength, power and motor performance in 14 highly skilled track and field athletes (e.g. discus, hammer, javelin, shot put and weight). Knee extension strength increased significantly by 15% during steady maximal isometric contractions and by 24% during rapid isometric contractions at maximal effort after the 16-week training programme (P < 0.05). Increases in EMG amplitude and rate of EMG activation indicated that improvements to the pattern of neural drive occurred with sport-specific resistance training (P < 0.05). The maximality and pattern of neural drive did not change in the control group. 相似文献

20世纪90年代中期以后,随着电子政府服务的发展,美国联邦政府一些跨机构工作小组开始致力于政府信息定位服务(GILS)的相关调查研究,并在大量合作项目的基础上构建起联邦政府的GILS框架。此后,美国各州政府和机构也在此基础上探索构建了各具特色的GILS服务。GILS现已逐渐融合到美国电子政府整体建设之中,不仅通过因特网为公民提供政府数字信息,而且还可提供广泛的政府服务。各种类型的GILS服务之间的交流与合作也在积极展开。 相似文献

The development of reasoning skills, higher-level thinking skills, and science process skills are some of the benefits students can realize by participating in inquiry in the science laboratory. We used student responses to the Alternative Assessment of Science Process Skills (AASPS) developed by the Missouri Department of Education and the Department of Educational Assessment to develop the Science Process Skills Inventory (SPSI). The SPSI was then used to analyze student efforts at writing experimental designs. Our goal was to gain insight into factors that may be related to students successfully designing experiments. The instrument guides teachers and researchers in assessing seven main components of experimental designs. Each component consists of elements unique to the specific laboratory exercise. Subsequent to its development, the instrument was used to score 364 student responses to the “design an experiment” portion of an alternative assessment instrument for science process skills. Results indicate that explicit, incremental development of the science process skills of formulating hypotheses and identifying variables, together with model examples, may be a means to facilitate student success in designing science experiments. Implications for the classroom and for research are discussed. © 1996 John Wiley & Sons, Inc. 相似文献

Carbohydrate (CHO) availability could alter mucosal immune responses to exercise. This study compared the effect of three dietary approaches to CHO availability on resting and post-exercise s-IgA levels. Elite race walkers (n = 26) adhered to a high CHO diet (HCHO), periodised CHO availability (PCHO) or a low CHO/high fat diet (LCHF) for 3 weeks while completing an intensified training program. HCHO and PCHO groups consumed 8.0–8.5 g.kg?1 CHO daily, with timing of ingestion manipulated to alter CHO availability around key training sessions. The LCHF diet comprised 80% fat and restricted CHO to < 50 g.day?1. A race walk test protocol (19 km females, 25 km males) was completed at baseline, after adaptation, and following CHO restoration. On each occasion, saliva samples were obtained pre- and post-exercise to quantify s-IgA levels. Resting s-IgA secretion rate substantially increased ~ two-fold post-intervention in all groups (HCHO: 2.2 ± 2.2, PCHO: 2.8 ± 3.2, LCHF: 1.6 ± 1.6; fold-change± 95% confidence limits), however, no substantial differences between dietary treatments were evident. Post-exercise, substantial 20–130% increases in s-IgA concentration and 43–64% reductions in flow rate occurred in all dietary treatments, with trivial differences evident between groups. It appears that high volume training overrides any effect of manipulating CHO availability on mucosal immunity in elite athletes. 相似文献

Over the past two decades, there have been a number of sociological investigations of participation by women in sports that had previously appeared to have been played exclusively by men. These investigations have rightly celebrated this participation as examples of greater physical empowerment, choice and freedom for women in sport. Several of these investigations have gone further by utilizing McCaughey’s notion of physical feminism to argue that participation in these sports is indicative of a broader feminist political challenge. This paper contends that this characterization of the broader political challenge is a misinterpretation of McCaughey’s physical feminism. Further, this misinterpretation is indicative of the theoretical underpinnings of the shift from a second wave radical feminism to a third wave celebrity feminism. This paper proposes a set of commitments that would be necessary, although not sufficient, to see these women’s leagues as feminist organizations that politically challenge patriarchal power. 相似文献

The most useful kind of norms are local norms collected by a test interpreter on a population with which s/he is familiar. We present a rationale for the use of local norms and a procedure, illustrated with an example, for updating a norm group's test score mean and variance. It was concluded that test interpreters should build local norms to be used in conjunction with norms based on a national sample, since local norms can be more recent, relevant, and representative for local groups. 相似文献
