Coping style plays an important role in children’s wellbeing. This paper describes the patterns of associations between children’s self-reported coping styles and symptoms of anxiety in order to determine whether particular dimensions are associated with better adjustment. Participants were 2566 children (1268 girls, 1298 boys) aged 7–11 years attending 15 schools in the South East of England. Results showed that aspects of coping were differentially associated with children’s self-reported anxiety. Patterns of association also varied by age and gender. Dimensions of coping were shown to form distinct adaptive and maladaptive coping styles which were also differentially associated with anxiety. Analysis of these styles indicated that it is the absence of maladaptive coping strategies, rather than the presence of adaptive strategies, that is significant in emotional wellbeing. These findings suggest that interventions designed to reduce or extinguish maladaptive coping styles may be of particular benefit in facilitating emotional wellbeing.  相似文献   

Use of NSE/PS2m-transgenic mice in the study of the protective effect of exercise on Alzheimer's disease     

Jun Y Cho  Dae Y Hwang  Tae S Kang  Dong H Shin  Jin H Hwang  Chae H Lim 《Journal of sports sciences》2013,31(11):943-951

In its late stage, Alzheimer's disease results in progressive muscle weakness in the arms and legs. The aim of this study was to determine whether mice expressing the skeletal muscle-specific mutant PS2 gene (a model of Alzheimer's disease) are a useful experimental system to study the protective effect of exercise on Aβ-42 reduction, improvement of behavioural function and changes in metabolic parameters. With this aim in mind, the transgenic mice were subjected to treadmill exercise for 3 months. The results showed that in transgenic mice, but not in normal mice, treadmill exercise resulted in a reduction of Aβ-42 deposits and an improvement in behavioural function, thereby restoring normal concentrations of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglyceride. Thus, exercise may represent a practical therapeutic strategy for use with human patients with Alzheimer's disease.  相似文献   

Effect of shoe wearing time and midsole hardness on ground reaction forces,ankle stability and perceived comfort in basketball landing

ABSTRACT

This study examined the effect of wearing time on comfort perception and landing biomechanics of basketball shoes with different midsole hardness. Fifteen basketball players performed drop landing and layup first step while wearing shoes of different wearing time (new, 2-, 4-, 6- and 8-week) and hardness (soft, medium and hard). Two-way ANOVA with repeated measures was performed on GRF, ankle kinematic and comfort perception variables. Increased wearing time was associated with poorer force attenuation and comfort perception during landing activities (p < 0.05). The new shoes had significantly smaller forefoot (2- and 4-week) and rearfoot peak GRF impacts (all time conditions) in drop landing and smaller rearfoot peak GRF impact (6- and 8-week) in layup; shoes with 4-week of wearing time had significantly better perceptions of forefoot cushioning, forefoot stability, rearfoot cushioning, rearfoot stability and overall comfort than the new shoes (p < 0.05). Compared with hard shoes, the soft shoes had better rearfoot cushioning but poorer forefoot cushioning (p < 0.05). Shoe hardness and wearing time would play an influential role in GRF and comfort perception, but not in ankle kinematics. Although shoe cushioning performance would decrease even after a short wearing period, the best comfort perception was found at 4-week wearing time.  相似文献   

The Influence of Chosun Marathon Bogeuphoe on Realisation of Korea's National Identity during the US Military Government Era (1945–1948)     

Moongi Cho 《国际体育史杂志》2013,30(3):297-314

Chosun Marathon Bogeuphoe was a Korean marathoner training centre, which was organised in August 1947, in the era of poverty and social upheaval under the US Army Military Government in Korea (USAMGIK), and produced the world top-class marathoners, including Suh Yun-bok, Ham Kee-yong and Choi Yun-chil. This study aims to investigate the sport historical significance of the Bogeuphoe in terms of operation, organisation, venues and funds by content analysis of John R. Hodge's telegraphic messages, the record of Special Committee for Anti-ethnic-act Investigation, the primary historical materials including 1947 Boston Marathon winner, Suh Yun-bok's notes, newspapers, photographs, autobiography, memoirs and interviews with Ham Kee-yong, the 1950 Boston Marathon winner. The findings of this study are that the Chosun Marathon Bogeuphoe contributed greatly to bring forth Korea's golden age in marathon history and served as a diplomatic advance guard in enhancing Korea's national prestige abroad and opening up a way-out for the nation's independence. This gives a valuable lesson to recent sport administrators and sport associations occasionally blamed for their unsuitable management despite the affluence of human and material resources. This study is expected to add to the literature to be used as a reference for the study of Korean sport associations' history.  相似文献

Content analysis of the 20 most influential articles in PIQ     

Yonjoo Cho  Sunyoung Park 《Performance Improvement Quarterly》2012,25(3):7-22

The purpose of this study is to examine key research themes in human performance technology (HPT) through content analysis of the 20 most influential articles identified in Cho, Jo, Park, Kang, and Chen (2011). Three questions guiding this inquiry are: (1) What are the key themes of the 20 most influential articles in PIQ, (2) What information do the 20 most influential articles add to an understanding of HPT, and (3) What are the implications of the content analysis for HPT research practices? Five key themes emerged from the content analysis, including instructional design, HPT scholarship, performance technology, performance support, and transfer of training. HPT scholarship was the most distinctive key research theme in this study. The qualitative details about the 20 most influential articles were provided, related issues were discussed, and implications for research practice were articulated.  相似文献   

Accelerating chronically unresponsive children to tier 3 instruction: what level of data is necessary to ensure selection accuracy?     

Compton DL  Gilbert JK  Jenkins JR  Fuchs D  Fuchs LS  Cho E  Barquero LA  Bouton B 《Journal of learning disabilities》2012,45(3):204-216

Response-to-intervention (RTI) approaches to disability identification are meant to put an end to the so-called wait-to-fail requirement associated with IQ discrepancy. However, in an unfortunate irony, there is a group of children who wait to fail in RTI frameworks. That is, they must fail both general classroom instruction (Tier 1) and small-group intervention (Tier 2) before becoming eligible for the most intensive intervention (Tier 3). The purpose of this article was to determine how to predict accurately which at-risk children will be unresponsive to Tiers 1 and 2, thereby allowing unresponsive children to move directly from Tier 1 to Tier 3. As part of an efficacy study of a multitier RTI approach to prevention and identification of reading disabilities (RD), 129 first-grade children who were unresponsive to classroom reading instruction were randomly assigned to 14 weeks of small-group, Tier 2 intervention. Nonresponders to this instruction (n = 33) were identified using local norms on first-grade word identification fluency growth linked to a distal outcome of RD at the end of second grade. Logistic regression models were used to predict membership in responder and nonresponder groups. Predictors were entered as blocks of data from least to most difficult to obtain: universal screening data, Tier 1 response data, norm referenced tests, and Tier 2 response data. Tier 2 response data were not necessary to classify students as responders and nonresponders to Tier 2 instruction, suggesting that some children can be accurately identified as eligible for Tier 3 intervention using only Tier 1 data, thereby avoiding prolonged periods of failure to instruction.  相似文献   

Predicting Suicide Risks Among Outpatient Adolescents Using the Family Environment Scale: Implications for Practice and Research     

Christopher F. Lucey  Sarah K. Y. Lam 《International journal for the advancement of counseling》2012,34(2):107-117

This study was designed to identify characteristics of family functioning that relate to suicide potential in an outpatient adolescent population. Participants included 51 adolescents between the ages of 14 and 18 who were involved in outpatient counselling. The Family Environment Scale and the Suicide Probability Scale were used to assess adolescents’ perception of family social climate and degree of suicide risk respectively. Results revealed significant correlations between suicide risk and family systems characterized by heightened conflict and lower levels of cohesion, independence, and organization. A stepwise multiple regression analysis suggested that organization (related to clarity and structure in family activities and responsibilities) was the strongest predictor of suicide risk. Implications for research and practice are considered.  相似文献   

Investigating relationships between features of learning designs and student learning outcomes     

Carmel McNaught  Paul Lam  Kin Fai Cheng 《Educational technology research and development : ETR & D》2012,60(2):271-286

This article reports a study of eLearning in 21 courses in Hong Kong universities that had a blended design of face-to-face classes combined with online learning. The main focus of the study was to examine possible relationships between features of online learning designs and student learning outcomes. Data-collection strategies included expert reviews of the learning designs, student surveys of perceptions of the web environment and their own learning outcomes, and a SOLO (structure of observed learning outcomes) analysis of assessment evidence of student learning outcomes. The findings of this correlational study indicate mild relationships between features of learning design and student perceptions of their learning outcomes. Both the provision of learning resources and the engagement of students in online communication relate to aspects of learning (acquisition of knowledge and skills, and enhancement of learning motivation). Also, the relationship was stronger when eLearning strategies were more extensively used. However, no relationship was found between learning design and the student performance in assessment tasks, possibly because of the limited assessment data that was examined.  相似文献   

Time With Peers From Middle Childhood to Late Adolescence: Developmental Course and Adjustment Correlates     

Chun Bun Lam  Susan M. McHale  Ann C. Crouter 《Child development》2014,85(4):1677-1693

This study examined the developmental course and adjustment correlates of time with peers from age 8 to 18. On seven occasions over 8 years, the two eldest siblings from 201 European American, working‐ and middle‐class families provided questionnaire and/or phone diary data. Multilevel models revealed that girls' time with mixed‐/opposite‐sex peers increased beginning in middle childhood, but boys' time increased beginning in early adolescence. For both girls and boys, time with same‐sex peers peaked in middle adolescence. At the within‐person level, unsupervised time with mixed‐/opposite‐sex peers longitudinally predicted problem behaviors and depressive symptoms, and supervised time with mixed‐/opposite‐sex peers longitudinally predicted better school performance. Findings highlight the importance of social context in understanding peer involvement and its implications for youth development.  相似文献
