This study examined to what extent adolescents’ and their friends’ risk behaviors (i.e., delinquency and alcohol use) hinder or promote their academic achievement (grade point average [GPA]), and vice versa. Longitudinal data were used (N = 1,219 seventh- to ninth-grade adolescents; Mage = 13.69). Results showed that risk behaviors negatively affected adolescents’ GPA, whereas GPA protected against engaging in risk behaviors. Moreover, adolescents tended to select friends who have similar behaviors and friends’ behaviors became more similar over time (same-behavior selection and influence). Furthermore, although same-behavior effects seemed to dominate, evidence was found for some cross-behavior selection effects and a tendency in seventh grade for cross-behavior influence effects. Concluding, it is important to investigate the interplay between different behaviors with longitudinal social network analysis. 相似文献

Stereotypes, prejudice, and discrimination against the elderly (ageism) may manifest themselves in children at an early age. However, the factors influencing this phenomenon are not well known. Using both explicit and open-ended questions, this study analyzed the influence of personal and familial parameters on the views of 1,151 seven- to sixteen-year-old Belgian children and adolescents on the elderly. Four factors were found to affect these views: gender (girls had slightly more positive views than boys), age (ageism was lowest in 10- to 12-year-old, reminiscent of other forms of stereotypes and cognitive developmental theories), grandparents’ health, and most importantly, quality of contact with grandparents (very good and good contacts correlated with more favorable feelings toward the elderly, especially in children with frequent contacts). 相似文献

The aim of this study was to examine the acute effects of prolonged static stretching (SS) on running economy. Ten male runners (VO2(peak) 60.1 +/- 7.3 ml x kg(-1) x min(-1)) performed 10 min of treadmill running at 70% VO2(peak) before and after SS and no stretching interventions. For the stretching intervention, each leg was stretched unilaterally for 40 s with each of eight different exercises and this was repeated three times. Respiratory gas exchange was measured throughout the running exercise with an automated gas analysis system. On a separate day, participants were tested for sit and reach range of motion, isometric strength and countermovement jump height before and after SS. The oxygen uptake, minute ventilation, energy expenditure, respiratory exchange ratio and heart rate responses to running were unaffected by the stretching intervention. This was despite a significant effect of SS on neuromuscular function (sit and reach range of motion, +2.7 +/- 0.6 cm; isometric strength, -5.6% +/- 3.4%; countermovement jump height -5.5% +/- 3.4%; all P < 0.05). The results suggest that prolonged SS does not influence running economy despite changes in neuromuscular function. 相似文献

Since Hugh Montgomery discovered the first of what are now nearly 200 "fitness genes", together with rapid advances in human gene therapy, there is now a real prospect of the use of genes, genetic elements, and/or cells that have the capacity to enhance athletic performance (to paraphrase the World Anti-Doping Agency's definition of gene doping). This overview covers the main areas of interface between genetics and sport, attempts to provide a context against which gene doping may be viewed, and suggests a futuristic legitimate use of genomic (and possibly epigenetic) information in sport. 相似文献

The present study evaluated the effects of the On‐Task in a Box intervention on student on‐task behavior when used as a class‐wide intervention. The intervention package includes self‐monitoring, video modeling, and reinforcement contingency components. A multiple baseline design across three elementary classrooms was used to determine the effects of the intervention on student behavior. Results indicated immediate increases in on‐task behavior in all classrooms. Calculation of nonoverlap of all pairs’ effect sizes indicated strong intervention and maintenance effects on on‐task behavior of students in all classrooms. Social validity data were also collected, which indicated adequate validity of the intervention. Results of the study suggest that the intervention package may be effective for improving class‐wide levels of on‐task behavior. 相似文献

This article presents detailed findings from the qualitative or interpretive phase of a mixed-methods case study focusing on the professional identities and lived experiences of research among six lecturers working in different capacities across the field of education in a ‘teaching-led’ higher education institution. Building upon the quantitative phase published earlier in this journal, factors both facilitating (e.g. research infrastructure, support for doctoral study) and constraining (e.g. time, space, workload, critical mass, ‘practitioner bond professionalism’, ‘organisational socialisation’, networks, roles and responsibilities, power relationships) research activity are identified. These are considered in the context of an institution often recruiting staff with ‘non-traditional’ backgrounds from within ‘the professions’ (e.g. from schools and colleges without doctorates) looking to become more ‘research-informed’ and establish a more vibrant and sustainable research culture. Recommendations for further development focus on ‘identity transitions’ and ‘cultural transformation’, emphasising the importance of research leadership and its distribution throughout the organisation. With current trends towards the apparent intensification and prioritisation of research activity over teaching, findings are considered particularly important for institutions of a similar nature to the one described here, for education departments in larger institutions also on similar journeys, and in light of an anticipated increase in demand for research activity arising from the expansion of higher education provision in further education and the private sector, where recruitment from within ‘the professions’ to teach across ‘vocational’ programmes is common. 相似文献

Comprehensive schoolwide initiatives like integrated multitiered systems of support (I-MTSS) and universal design for learning (UDL) present opportunities for large-scale impact on improving teacher instructional practices and, therefore, student outcomes. Specifically, implementing I-MTSS and UDL concurrently presents an opportunity to enhance and improve universal instruction for all students. This mixed-methods study explored current Tier 1 practices in elementary schools across the United States. Findings revealed that I-MTSS and UDL are perceived as being implemented concurrently. In addition, school personnel identified specific barriers to implementation. 相似文献

There is limited literature on emerging young adult (EYA) care partners, despite a recent rise in interest in this group. The purpose of this study is to compare EYA care partners and their non-care partner peers in the domains of academic achievement and engagement, employment, health-related behaviors and self-care, and mental health and respite, as well as to assess EYA care partners’ burden and potential for positive psychosocial sequelae and life changes as a result of their role. Further, within EYA care partners, we examine the relationship between mental health variables and care partner-relevant variables. Two hundred undergraduates (100 care partners and 100 non-care partners) completed measures of academic achievement and engagement (grade point average and credit load), employment (number of paid positions held and number of hours worked per week), health-related behavior/self-care (visits to the dentist, primary care physician, optometrist, diet healthfulness, exercise, cigarette smoking, and drinks per week) and mental health/respite (depression, anxiety, loneliness, drinking, social support, peer pressure, vacation recency, and frequency). Care partners completed measures of spiritual well-being, burden, meaning, and benefit-finding, as well as provided qualitative feedback on how caregiving changed their lives. EYA care partners and non-care partners did not differ on any variables examined except for the number of jobs held, as EYA care partners held more paid jobs than EYA non-care partners. EYA care partners showed moderate burden and high levels of finding meaning/benefit, the latter of which was supported by the themes that emerged from their qualitative data. Within EYA care partners, we found that depression and anxiety (mental health variables) were significantly related to spiritual well-being, burden, benefit finding, and finding meaning through caregiving (care partner-relevant variables). It is encouraging that the care partner and non-care partner groups were similar in domains critical for this age group, such as academic achievement and engagement. 相似文献
