An Examination and Validation of an Adapted Youth Experience Scale for University Sport     

Scott Rathwell  Bradley W. Young 《Measurement in physical education and exercise science》2016,20(4):208-219

Limited tools assess positive development through university sport. Such a tool was validated in this investigation using two independent samples of Canadian university athletes. In Study 1, 605 athletes completed 99 survey items drawn from the Youth Experience Scale (YES 2.0), and separate a priori measurement models were evaluated (i.e., 99 items, YES 2.0, YES for Sport [YES-S]). Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) results indicated issues with model fit. Post-hoc modifications improved fit, resulting in a 46-item, 9-factor model with five positive and four negative dimensions. In Study 2, 511 athletes completed the same items. The resultant model was confirmed using both CFA (comparative fit index [CFI] = .911, standardized root mean square residual [SRMR] = .056, root mean square error of approximation [RMSEA] = .040) and ESEM (CFI = .956, SRMR = .023, RMSEA = .034). The resultant University Sport Experience Survey provides a reliable and factorially valid instrument for measuring development in university sport.  相似文献   

Accuracy of activPAL Self-Attachment Methods     

Nina L. Kringen  Genevieve N. Healy  Elisabeth A. H. Winkler 《Measurement in physical education and exercise science》2016,20(3):159-166

This study examined the accuracy of self-attachment of the activPAL activity monitor. A convenience sample of 50 participants self-attached the monitor after being presented with written material only (WMO) and then written and video (WV) instructions; and completed a questionnaire regarding the acceptability of the instructional methods. Participants positioned the monitor lower than the instructed position on the thigh (WMO ?5.15 ± 2.75 cm, WV ?4.16 ± 2.15 cm; p = .008 difference) and approximately 2 cm laterally from the thigh midline (WMO 1.90 ± 0.92 cm; WV 2.08 ± 1.24 cm). The orientation of the device was positioned correctly along the midline (within < 1° of vertical). Acceptability was high for both instructional methods although preference was shown for the WV instruction. In conclusion, participants consistently self-attached the activPAL close to the intended placement with either instructional method. The addition of video instruction produced a slightly more accurate attachment and was preferred by the participants.  相似文献   

人权保障视野下强制辩护制度探讨     

曹文安  刘方权 《福建工程学院学报》2006,4(5):571-574

强制辩护制度对保障犯罪嫌疑人、被告人的权利有重要意义，在人权保障的大背景下，构建强制辩护制度显得尤为必要。我国应当构建全面的强制辩护制度，即在刑事诉讼的侦查、起诉、审判程序中，没有辩护人为被告人、犯罪嫌疑人辩护，则刑事诉讼程序不能继续进行。这种强制是对公检法机关、对政府、对律师以及对犯罪嫌疑人、被告人的强制。构建强制辩护制度是人权保障必然的价值选择，也是重新确立律师应有的社会地位．改善律师生存环境的需要。  相似文献   

Body composition of female road and track endurance cyclists: Normative values and typical changes     

Eric C. Haakonssen  Martin Barras  Louise M. Burke  David G. Jenkins  David T. Martin 《European Journal of Sport Science》2016,16(6):645-653

The aims of this study were to describe normative values and seasonal variation of body composition in female cyclists comparing female road and track endurance cyclists, and to validate the use of anthropometry to monitor lean mass changes. Anthropometric profiles (seven site skinfolds) were measured over 16 years from 126 female cyclists. Lean mass index (LMI) was calculated as body weight?×?skinfolds^?x. The exponent (x) was calculated as the slope of the natural logarithm of body weight and skinfolds. Percentage changes in LMI were compared to lean mass changes measured using dual-energy X-ray absorptiometry (DXA) in a subset of 25 road cyclists. Compared to sub-elite and elite cyclists, world class cyclists were (mean [95% CI]) 1.18?kg [0.46, 1.90] and 0.60?kg [0.05, 1.15] lighter and had skinfolds that were 7.4?mm [3.8, 11.0] and 4.6?mm [1.8, 7.4] lower, respectively. Body weight (0.41?kg [0.04, 0.77]) and skinfolds (4.0?mm [2.1, 6.0]) were higher in the off-season compared to the early-season. World class female road cyclists had lower body weight (6.04?kg [2.73, 9.35]) and skinfolds (11.5?mm [1.1, 21.9]) than track endurance cyclists. LMI (mean exponent 0.15 [0.13, 0.18]) explained 87% of the variance in DXA lean mass. In conclusion, higher performing female cyclists were lighter and leaner than their less successful peers, road cyclists were lighter and leaner than track endurance cyclists, and weight and skinfolds were lowest early in the season. LMI appears to be a reasonably valid tool for monitoring lean mass changes.  相似文献   

Lower limb alignment characteristics are not associated with running injuries in runners: Prospective cohort study     

Luiz Carlos Hespanhol Junior  Aline Carla Araújo de Carvalho  Leonardo Oliveira Pena Costa 《European Journal of Sport Science》2016,16(8):1137-1144

There is conflicting evidence on the association between lower limb alignment characteristics and the incidence of running-related injury (RRI). Therefore, the primary aim of this study was to investigate the association between lower limb alignment characteristics and the incidence proportion of RRI in a convenience sample of recreational runners. A total of 89 recreational runners were included in this prospective cohort study. These participants had been running for at least six months and were injury-free at baseline. Lower limb alignment measurements were conducted in order to calculate lower limb discrepancy, Q-angle, subtalar angle and plantar index. All participants also answered a baseline and biweekly online surveys about their running routine, history of RRI and newly developed RRI over a period of 12 weeks. The prevalence of previous RRI and the 12-week incidence proportion of new RRI were calculated. Logistic regression analysis was performed to estimate the association between lower limb length discrepancy, Q-angle, subtalar angle and plantar ach index with the incidence proportion of RRI. The prevalence of previous RRI was 55.1% (n?=?49). The 12-week incidence proportion of new RRI was 27.0% (n?=?24). Muscle injuries and tendinopathies were the main types of RRI identified. The lower leg and the knee were the main anatomical regions affected. We did not find significant associations between lower limb length discrepancy, Q-angle, subtalar angle and plantar arch index and injury occurrence.  相似文献   

司法程序的法理解析     

陈亚军  谢祥为 《江西师范大学学报(哲学社会科学版)》2004,37(3):41-43

司法程序的任务就是规制司法权以及当事人的诉讼行为，使案件能够在公平、公正的氛围中得以解决。然而，司法程序的意义又不能仅仅局限在其手段上，因为司法程序本身就是一个社会明程序的标志，其自身意义不可低估。就司法程序的构成上讲，时间、空间、仪式缺一不可，否则就不符合程序之特点。在司法程序的价值体系中，应当对公平与效率进行整舍，惟有此，我们才不至于从一个极端走向另一个极端。  相似文献   

Have a Legal Question Without the Resources to Get an Answer?     

Hope Dunbar 《Journal Of Archival Organization》2016,13(3-4):137-141

This article explores the Western New York's Library Resources Council's Ask the Lawyer Program. The program provides a timely model for local cultural heritage communities, such as archives, to collectively retain a lawyer in a non-representational capacity to answer both specific and hypothetical questions that arise as a result of their work.  相似文献

法律儒家化新论     

吴正茂  赵永伟 《安徽教育学院学报》2006,24(2):57-60

“法律儒家化”是中国法制史上的基本观点,但对此观点需要全面地认识和辩证地分析,不能绝对化和片面化。从魏晋至隋唐儒学发展的态势、法律发展变化的实际情形和法律儒家化的特殊机理三个方面对法律儒家化重新予以解释和剖析,可以看出,法律儒家化的观点虽然从总体上能够成立,但不宜以绝对化、片面化的态度视之,而要深入认识我国古代法律发展过程的复杂性。  相似文献
