The impact of early physical and sexual abuse (EPA/SA) occurring in the first 5 years of life was investigated in relation to depressive and internalizing symptomatology and diurnal cortisol regulation. In a summer camp context, school-aged maltreated ( n  =   265) and nonmaltreated ( n  =   288) children provided morning and late afternoon saliva samples on 5 consecutive days. Child self-report and adult observer reports of child internalizing and depressive symptoms were obtained. Children experiencing EPA/SA and high depressive or internalizing symptoms uniquely exhibited an attenuated diurnal decrease in cortisol, indicative of neuroendocrine dysregulation. These results were specific to EPA/SA rather than later onset physical or sexual abuse or early occurring neglect or emotional maltreatment.  相似文献

This study examined relations among early family risk, children's behavioral regulation at 54 months and kindergarten, and academic achievement in first grade using data on 1,298 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development. Family risk was indexed by ethnic minority status, low maternal education, low average family income from 1 - 54 months, and high maternal depressive symptoms from 1 - 54 months. Results of structural equation modeling indicated that minority status, low maternal education, and low family income had significant negative effects on reading, math, and vocabulary achievement in first grade. Modest indirect effects were also found from ethnicity, maternal education, and maternal depressive symptoms, through 54-month and kindergarten behavioral regulation to first-grade achievement. Discussion focuses on the importance of behavioral regulation for school success especially for children facing early risk.  相似文献

ABSTRACT

This study examined the simultaneous effects of relative age and biological maturity status upon player selection in an English professional soccer academy. A total of 202 players from the U9 to U16 age groups, over an eight-year period (total of 566 observations), had their relative age (birth quarter) and biological maturity (categorised as late, on-time or early maturing based upon the Khamis-Roche method of percentage of predicted adult height at time of observation) recorded. Players born in the first birth quarter of the year (54.8%) were over-represented across all age groups. A selection bias towards players advanced in maturity status for chronological age emerged in U12 players and increased with age; 0% of players in the U15 and U16 age group were categorised as late maturing. A clear maturity selection bias for early maturing players was, however, only apparent when the least conservative criterion for estimating maturity status was applied (53.8% early and 1.9% late maturing in the U16 age group). Professional football academies need to recognise relative age and maturation as independent constructs that exist and operate independently. Thus, separate strategies should perhaps be designed to address the respective selection biases, to better identify, retain and develop players.  相似文献

Background: In the U.S. college/university setting, physical activity courses are often offered as part of the general education program, where students earn college credits towards the completion of their degree program. These courses are typically taught by graduate teaching assistants (GTAs), who face several challenges in instructing undergraduate students. Often, GTAs are thrust into their roles without the preparation that traditional teachers receive as customary with education degrees. Literature on need supportive teacher training, as part of self-determination theory, indicates that teachers including GTAs, can be successfully trained to meet the needs of their students regardless of years of previous experience. Presently, there is little information on the impact of such a training program from the perspective of the GTAs participating in the program.

Purpose: The aim of this study is to provide in-depth perspectives on need supportive training through examination of GTAs reflections of the training process.

Participants and setting: Fourteen GTAs from a university physical activity and healthful living program were recruited for this study, but two dropped out. All participants taught one of the following courses: aerobics, basketball, body conditioning, bowling, flag football, golf, racquetball, soccer, tennis, ultimate frisbee, volleyball, or yoga.

Data collection: Teaching reflections were written by participants at the end of a year-long training program.

Data analyses: Written reflections completed by the GTAs were analyzed via content analysis. Data were organized by how strategies were implemented, most/least successful use of the strategies, and adherence to the training. Once organized, the data was examined by two different researchers independently and themes were shared with participants as part of the member checking process. Searches for negative cases were utilized during the analysis process as well.

Findings: Across the data, it was determined that the GTAs felt the training to be beneficial, influencing much of how they worked with students. Results suggested that GTAs found several ways to implement the reviewed need supportive teaching strategies, including giving students the choice of activities and group membership. They were also able to better respond to students’ negative affect and give explanatory rationales. Goal setting was a consistently used strategy by the GTAs; however, it was cited as one of the least successful strategies due to the inability to effectively follow-up on the goals made during classes with the students. Additionally, it was noted that the GTAs had difficulties with devising their own ways of implementing the strategies and relied heavily on the examples that were provided during their training sessions.

Conclusion: In better understanding, the perceptions of GTAs who engage in need supportive training programs, researchers can better gauge the effectiveness of such programs and how they can be improved. Future research should focus on how to help GTAs to engage in more creative ways of using need supportive teaching strategies in physical activity environments.  相似文献

The present study examined the effects of sexual objectification of female artists in music videos on male undergraduates' sexual beliefs. Findings showed that participants who viewed music videos of highly objectified female artists reported more adversarial sexual beliefs, more acceptance of interpersonal violence, and, at a level of marginal significance, more negative attitudes about sexual harassment than participants assigned to low-sexual objectifying music videos by the same female artists. Path models indicated that adversarial sexual beliefs mediated the relationship between condition, and (1) acceptance of interpersonal violence and (2) negative attitudes regarding sexual harassment.  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

The authors investigated whether students receiving short–term individual counseling at a university counseling center showed progress as evidenced by perceived client and counselor outcomes and the roles that client readiness to change and working alliance played in this setting. The results indicated that the counselor reports, not the client reports, reflected statistically significant change in client symptoms. Changes in symptom severity were not associated with working alliance and readiness to change.  相似文献

With continuing pressure to publish or perish, interventions such as writing groups are increasingly part of the academic landscape. In this paper, we discuss our writing group's experiment with collaborative writing, which came unstuck as simmering concerns led to a mutiny within the group. The mutiny provided insights into tensions that are inevitably present in writing groups and collaborative writing exercises but are seldom written about. We explore these tensions via a collaborative autoethnography, drawing on published literature on writing groups and collaborative writing. The mutiny revealed three key dynamics. Experienced voices can have an important role to play but these voices need to be moderated so that other voices might be recognised and valued. Pleasure and productivity are two necessary components for sustaining writing groups and writing collaborations. Finally, hierarchies in the academic context are inescapable but they can be renegotiated so that more enabling power relations can be generated.  相似文献
