The overall purpose of this study was to create a model of positive youth development (PYD) through sport grounded in the extant qualitative literature. More specifically, the first objective was to review and evaluate qualitative studies of PYD in sport. The second objective was to analyze and synthesize findings from these studies. Following record identification and screening, 63 articles were retained for analysis. Meta-method analysis revealed strengths of studies were the use of multiple data collection and validity techniques, which produced high-quality data. Weaknesses were limited use of ‘named’ methodologies and inadequate reporting of sampling procedures. Philosophical perspectives were rarely reported, and theory was used sparingly. Results of an inductive meta-data analysis produced three categories: PYD climate (adult relationships, peer relationships, and parental involvement), life skills program focus (life skill building activities and transfer activities), and PYD outcomes (in personal, social, and physical domains). A model that distinguishes between implicit and explicit processes to PYD is presented.  相似文献

How do you live in a time when most people believe you are dead—from a people of the past—and you feel you have been made allergic to your true roots? You do, you just do. ?Geobe (2003, p. 55)  相似文献

Seventeen deaf children and a matched group of 17 nonhearing impaired children were assessed to compare rate of basic concept development. The results indicate that deaf children scored approximately two standard deviations below their matched nonhearing impaired peers. Additionally, the deaf children exhibited a relatively flat subtest proffle, suggesting that basic concepts that have not been specifically taught remain uniformly delayed for deaf children.  相似文献

This study investigates older persons engagement with digital interfaces as one important way to social inclusion. Digital exclusion and social exclusion are intrinsically intertwined, which put older persons at risk for exclusion. To construct meaningful educational practices for inclusion, more insight is needed to understand consequences of low digital competence. Eighteen men and women (retired) have been interviewed about their everyday encounters with digital interfaces. Results show how older persons ‘borrow’ knowledge from social networks or from contacts at previous workplace, to access technology and digital practices. Data also show a common acceptance of exclusion and changes in lifestyle. These fragile chains, put together to access digital practices jeopardise social inclusion understood as autonomy and participation in society. Informants did not mention community arrangements as resources for access and knowledge, which indicate that hard work is required to promote inclusion of this group. A possible way could be using the power of informally framed learning scenarios. Society cannot turn a blind eye to the fact that groups of citizens are hindered from developing capabilities to maintain a social life, to access the health sector, to enjoy integrity and independence and cultural recreation – to live a capable life.  相似文献

This study examined whether defending and passive bystanding during peer victimization episodes were associated with individual- and classroom-level efficacy to stop peer victimization. Self-report survey data were analyzed from 1,467 Swedish fourth-grade students (mean age = 10.55) from 100 classrooms in 63 schools. Multilevel analyses revealed that, when witnessing peer victimization, students more often defended victims if they were high in defender self-efficacy and if they belonged to classrooms high in collective efficacy. In contrast, students were more likely to remain passive if they were low in defender self-efficacy and if they belonged to classrooms low in collective efficacy. Taken together, our findings suggest that efficacy beliefs both at the individual and at the classroom level contribute to explaining variability in students' bystander behaviors, which has potential implications for prevention and intervention work.  相似文献

ABSTRACT

Yoga has been found to provide numerous health benefits to older adults including preventing or slowing physical frailty and subsequent functional limitations. The purpose of this study was to examine pre-frail or frail older adults’ beliefs about yoga as well as to identify barriers to participation. We recruited 37 older adults from a Faint, Fall, and Frailty Clinic at a medical center and asked them to complete questionnaires regarding their physical health and beliefs about yoga using the Beliefs About Yoga Scale. Frailty and fall risk were obtained through electronic health records. Participants’ had mean age of 72.81 years. Participants were considered to be prefrail (66.7%) or frail (33.3%), and most (78.4%) had fallen at least once in the past year. Over 72% of participants engaged in light physical activity. The BAYS mean score was 59.17 (SD = 12.5; Range 11–77). Higher scores indicted more optimistic beliefs about yoga. Over 90% of participants had not practiced yoga, 97.1% had no intentions to practice, 61.8% did not know locations placed where yoga classes were offered, 82.4% were unsure about the costs associated with yoga, and only 56.3% reported having transportation. The three primary barriers to practicing yoga were perceived difficulty of yoga practice, lack of motivation, and fear of injury. Participants held positive beliefs about yoga, yet had limited experience and little intention to participate indicating a need to provide targeted educational interventions to this population of older adults.  相似文献

Abstract

Energy turnover was assessed in two conditions of mixed ultra-endurance exercise. In Study 1, energy expenditure and intake were measured in nine males in a laboratory over 24 h. In Study 2, energy expenditure was assessed in six males during an 800-km Adventure race (mean race time 152.5 h). Individual correlations between heart rate and oxygen uptake ([Vdot]O2) were established during pre-tests when kayaking, cycling, and running. During exercise, energy expenditure was estimated from continuous heart rate recordings. Heart rate and [Vdot]O2 were measured regularly during fixed cycling work rates to correct energy expenditure for drift in oxygen pulse. Mean energy expenditure was 18,050 ± 2,390 kcal (750 ± 100 kcal · h?1) and 80,000 ± 18,000 kcal (500 ± 100 kcal · h?1) in Study 1 and Study 2 respectively, which is higher than previously reported. Energy intake in Study 1 was 8,450 ± 1,160 kcal, resulting in an energy deficit of 9,590 ± 770 kcal. Body mass decreased in Study 1 (?2.3 ± 0.8 kg) but was unchanged in Study 2. Fat mass decreased in Study 2 (?2.3 ± 1.5 kg). In Study 1, muscle glycogen content decreased by only 60%. Adventure racing requires a high energy expenditure, with large inter-individual variation. A large energy deficit is caused by inadequate energy intake, possibly due to suppressed appetite and gastrointestinal problems. The oxygen pulse, comparing start to 12 h of exercise and beyond, increased by 10% and 5% in Study 1 and Study 2 respectively. Hence, estimations of energy expenditure from heart rate recordings should be corrected according to this drift.  相似文献
