Adolescents’ ethnic–racial identity (ERI) formation represents an important developmental process that is associated with adjustment. The Identity Project intervention, grounded in developmental theory, was designed to engage adolescents in the ERI processes of exploration and resolution. The current small‐scale efficacy trial involved an ethnic–racially diverse sample of adolescents (N = 215; Mage = 15.02, SD = .68) from eight classrooms that were randomly assigned by classroom to the intervention or attention control group. Differences between conditions in ERI exploration at Time 2 were consistent with desired intervention effects; furthermore, higher levels of ERI exploration at Time 2 predicted increases in ERI resolution at Time 3 only for youth in the treatment condition. Findings provide preliminary evidence of program efficacy. 相似文献

In relation to teaching and learning approaches that improve student learning outcomes, threshold concepts have generated substantial interest in higher education. They have been described as ‘portals’ that lead to a transformed way of understanding or thinking, enabling learners to progress, and have been enthusiastically adopted to inform teaching approaches and curriculum design. A growing body of literature has critiqued the relevance and applicability of the threshold concept theory and identified threshold concepts relevant to specific disciplines. More recent research has identified how students cross these thresholds and provided measures of the successful acquisition of threshold concepts. This literature synthesis critiques existing evidence on threshold crossing and acquisition to provide a succinct and informative overview of the outcomes to date. Key questions relevant to educators and researchers investigating whether students acquire the threshold concepts associated with their teaching, arose from the literature synthesis. These were: whether or not threshold crossing can be measured; how variation in student learning can be addressed during measurement; tools that can be used for measuring threshold crossing; whether the way units or concepts are taught should alter prior to measurement, and the challenges and limitations of measuring threshold crossing. 相似文献

Currently, very little is known about the impact of short- or long-haul air travel on the sleep and wellbeing of wheelchair basketball athletes. Eleven national wheelchair basketball athletes wore actigraphy monitors prior, during, and after air travel to the United Kingdom. Upon arrival, participants rated their subjective jet-lag, fatigue, and vigor. Individuals traveled to the United Kingdom from different locations in Australia, the United States, and Europe and were categorised according to travel length [LONG (up to 30.2 h) or SHORT (up to 6.5 h)]. Linear mixed models determined effects of travel length on sleep and subjective ratings of jet-lag, fatigue, and vigor. During competition, subjective fatigue and jet-lag were substantially higher (ES = 0.73; ±0.77) and (ES = 0.57; ±0.60), subjective vigor was lower (ES = 1.94; ±0.72), and get-up time was earlier (ES = 0.57; ±0.60) for LONG when compared to SHORT. Travelling greater distances by airplane had a larger effect on subjective ratings of jet-lag, fatigue and vigor, rather than sleep. Irrespective of travel group, sleep and subjective responses were compromised, reflecting the travel requirements, competition-mediated influences, and/or due to a change in environment. 相似文献

Anterior cruciate ligament (ACL) injury prevention programmes have not been as successful at reducing injury rates in women’s basketball as in soccer. This randomised controlled trial (ClinicalTrials.gov #NCT02530333) compared biomechanical adaptations in basketball and soccer players during jump-landing activities after an ACL injury prevention programme. Eighty-seven athletes were cluster randomised into intervention (6-week programme) and control groups. Three-dimensional biomechanical analyses of drop vertical jump (DVJ), double- (SAG-DL) and single-leg (SAG-SL) sagittal, and double- (FRONT-DL) and single-leg (FRONT-SL) frontal plane jump landing tasks were tested before and after the intervention. Peak angles, excursions, and joint moments were analysed using two-way MANCOVAs of post-test scores while controlling for pre-test scores. During SAG-SL the basketball intervention group exhibited increased peak knee abduction angles (p = .004) and excursions (p = .003) compared to the basketball control group (p = .01) and soccer intervention group (p = .01). During FRONT-SL, the basketball intervention group exhibited greater knee flexion excursion after training than the control group (p = .01), but not the soccer intervention group (p = .11). Although women’s soccer players exhibit greater improvements in knee abduction kinematics than basketball players, these athletes largely exhibit similar biomechanical adaptations to ACL injury prevention programmes. 相似文献

AbstractThis paper considers the emergence of amateur women’s rowing between the late nineteenth and early twentieth centuries, in light of contemporaneous social norms relating to gender and sport. It does not seek to identify a foundational point for women’s rowing, nor does it offer a comprehensive survey of the development of the sport over this period. Instead, it considers women’s rowing in three key contexts: women’s university colleges, at the end of the nineteenth century; the first women-only rowing club on the Thames, established in 1896 by Dr Frederick Furnivall; and the formation of a governing body for the women’s sport in 1923. Analysis of the conditions within the sport in these environments, and their implications, leads to more nuanced consideration of the women’s sport, and of gender as a normative social construct more widely. Discussion focuses on gendered influences on sporting behaviour, manifested in institutional regulation and hegemonic authority, and the intersection of class and gender. 相似文献

Mindfulness-Based Interventions (MBIs) have been increasingly implemented in schools to foster better emotional regulation skills for students with special education needs such as learning disabilities (LDs). This pilot study aimed to evaluate the impact of a MBI on the need satisfaction of elementary students with severe LDs. A prospective quasi-experimental design involving one group and two time points was employed. A sample of 14 elementary school students from a severe LDs special education class participated in this project. Repeated-measures ANOVAs were conducted and revealed a significant reduction in need satisfaction, with a large effect size (η2 = .35). Contrary to our hypothesis, the MBI appeared to be negatively related to need satisfaction among participants. These results indicate that MBIs could be linked with better self-evaluation skills in students with severe LDs, which, in turn, may change (or increase the accuracy of) the perception that children have of their own need satisfaction. 相似文献

The aim of this study was to determine the effects of positive and negative outcome imagery on golf-putting performance. Players of both high and low ability performed a golf-putting task in three imagery conditions: (a) a positive outcome imagery condition, (b) a negative outcome imagery condition and (c) a no-imagery control condition. The task was conducted in a competitive setting, reducing the possibility of demand characteristics. We found that negative outcome imagery was detrimental to putting performance; however, performance in the positive outcome imagery condition was no better than performance in the control condition. There was also evidence to suggest that outcome imagery operated through the mechanism of confidence, as negative outcome imagery was detrimental to both confidence and performance. The results of the present study suggest that golfers should avoid visualizing negative images, as this could damage both confidence and performance. 相似文献

Abstract Our purpose was to determine the aerobic capacities (VO2max) of a group of black female adolescents (age = 11.4 ? 15.8 years) randomly chosen from a single urban school. Of 91 girls selected, 64 performed an incremental treadmill running test to volitional exhaustion and achieved VO2max as determined from expired gas measures. Other measures included height (m), weight (kg), and calf and triceps skinfolds (for % fat estimates). Girls were also asked whether they had achieved menarche. VO2max averaged 37.3 ± 6.2 ml·kg?1 ·min?1 and was significantly correlated (r[62]) with height (?.32, p < .01), body mass index (?.63, p < .001), and % fat (?.65, p < .001) but not with age (?.16, p > .10). Postmenarchal girls were significantly taller and older than premenarchal girls. Contrary to previous studies, the girls' VO2max values were not related to biological age. Our subjects' aerobic capacity values averaged 14% less than those of nonblack U.S. female adolescents previously reported in the literature. This difference in VO2max was primarily a function of body weight. Study implications support the possibility that overweight in adult black women may originate prior to or during early adolescence. Future longitudinal studies should be designed to investigate the effects of aerobic fitness on cardiovascular risk factor reduction in black adolescent girls. 相似文献
