Team handball is a popular sport worldwide that requires numerous throws to be made throughout the course of a game. Because of the upper extremity demands of repetitive throwing, it is possible that fatigue can alter the mechanics of a shot. The purpose of this study was to determine the influence of localised fatigue on jump shot kinematics and kinetics. Eleven male team handball players (23.1 ± 3.1 years; 185.1 ± 8.3 cm; 89.7 ± 12.2 kg) volunteered. An electromagnetic tracking system was used to examine the jump shot prior to and following localised fatigue. The fatiguing protocol consisted of throwing a 2.2 kg medicine ball into a rebounder until volitional fatigue. No significant kinematic or kinetic differences were observed following fatigue. Shoulder external rotation was ?74.8 ± 14.9° prior to and ?79.0 ± 14.7° following fatigue at MER. Scapula, external rotation at ball release (BR) prior to fatigue was ?2.2 ± 7.0° and ?3.2 ± 11.1° following fatigue. Scapular internal rotation, at maximum shoulder internal rotation (MIR), changed from 18.4 ± 11.2° to 20.4 ± 11.8°. Ball velocity decreased from19.8 m · s–1 to 18.8 m · s–1 (P = 0.12). Accuracy percentage in the pre-fatigue trials was 60.8 ± 14.1% and 52.8 ± 12.7% following fatigue (P = 0.20). While no significant changes were observed, it is possible that other fatiguing protocols that more closely represent the aerobic and throwing demands of the sport may have a greater effect on the kinematics and kinetics of the jump shot. 相似文献

Cognitive Development in Gifted Children: Toward a More Precise Understanding of Emerging Differences in Intelligence 总被引：3，自引：0，他引：3
To truly understand gifted performance, it is necessary to merge research on giftedness with current thinking in cognitive development and intelligence. This article presents traditional research on gifted children's cognitive development then considers how the application of newer models and theories from the field of cognitive development can be combined with research on giftedness to change the way people think about gifted performance. First four factors that have often been associated with giftedness are discussed from the perspectives of cognitive developmental psychology and gifted education. Next, emphasis is placed on investigating the strategic development of gifted children. Specifically, R. S. Siegler's (Emerging Minds: The Process of Change in Children's
Thinking, Oxford University Press, New York, 1996) model of strategy development is addressed in terms of what it may contribute to understanding gifted cognition. Finally, future lines of research using models from cognitive development and complex systems models of development are recommended. 相似文献

This research experimentally examined the effectiveness of the use of virtual racial embodiment in a digital gaming application for reducing bias against a non-dominant group. The findings of this study advance theory and have practical implications for the design of immersive diversity initiatives. We tested avatar creation and the gaming app as a new modality for stimulating perspective-taking. In addition, we explored how sex and race intersect in virtual embodiment and stereotyping. Results showed that creating and embodying a Black avatar produced more favorable beliefs about African American men, but not African American women, and greater support for “pro-minority” policies in comparison to creating and playing a White avatar. Avatar liking was a significant moderator, but self-presence had no effect. 相似文献

ABSTRACTIn the years since the fall of the civil–military dictatorships in the Southern Cone, considerable attention has been paid to first-person testimonies of human rights victims. A great number of these have been by women who narrated sexual political violence. However, while there has been work done on the relation between terror, trauma, and spectacle in postdictatorial television shows, rarely has this also included a gendered perspective. In this article we seek to open this area of discussion by evaluating the manner in which women’s televised testimonies of political sexual violence have been constructed on late night talk shows in Chile, using recent history and memory theory, as well as feminist theory on the representation of sexual violence in mass media. 相似文献

This study, guided by family communication patterns theory, examined the role of family communication in political socialization. We tested whether certain communication styles were associated with higher levels of political similarity within the family. Additionally, the independent influences of the mother and father, as well as the direction of these influences, were considered. Results suggest that different communication styles are associated with higher levels of political similarity. Additionally, it was found that children were more likely to share their mothers' political attitudes than their fathers'. Explanations for these findings are discussed and implications focusing on the role of communication in the socialization literature are considered. 相似文献

Attention-deficit/hyperactivity disorder (ADHD) was previously believed to be a disorder of childhood, with symptoms attenuating at the onset of puberty. Follow-up studies, however, suggest that the majority of children with ADHD continue to manifest symptoms into adulthood. Although the inattention components associated with ADHD persist into adulthood, the nature of the hyperactivity component is less well understood. For example, according to criteria established by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, hyperactivity in adolescents and adults may be limited to subjective feelings of restlessness. Recent studies with adults with ADHD have also reported that mental restlessness is commonly reported by individuals with the disorder. To better understand this characteristic of ADHD, the Internal Restlessness Scale (IRS) was developed. The results of the IRS suggest that (a) college students with ADHD report significantly higher ratings of internal restlessness than college students without ADHD, and (b) the IRS appears to have adequate test-retest reliability and a four-factor structure. Implications and suggestions for future research are discussed. 相似文献

The authors examined the social practices and outcomes of 23 immigrant and 16 nonimmigrant preschoolers in English only preschool classrooms. In both classrooms, the majority of the children (nearly two thirds) were immigrant, English language learners. The children's social attempts, social strategies, speech functions, and degree of social success were observed and comparisons were made between nonimmigrant and immigrant peers. There were similarities between groups in their social engagement and social construction strategies; there were differences in social roles, social language functions, and types of social construction strategies. There also were significant differences in the social success of the two groups. Immigrant children experienced rejection of their social bids more than their preschool peers did. Immigrant children also were less likely to be leaders and seemed positioned in a lower social status among their peers did. These results are discussed along with implications for educational practices. 相似文献
