关于校园排球文化内涵及其结构的文化学审视   总被引：3，自引：1，他引：2  

张庆凤 《南京体育学院学报(社会科学版)》2007,21(1):86-88

以文化学的角度诠释了校园文化、体育文化和校园体育文化的内涵,进而分析了校园排球文化的内涵、结构和外延。校园排球文化即为教师和学生在排球教学、排球活动和排球学习中,所形成物质财富和精神财富的总和。其结构包括排球制度文化、排球物质文化和排球精神文化。校园排球文化作为校园体育文化的重要一部分,不但对校园体育文化起到促进作用,同时对校园文化和体育文化也起到很大的促进作用,这构成校园排球文化广泛的外延。  相似文献

中国女排北京奥运会人员配备结构分析   总被引：1，自引：0，他引：1

中国女排在08年北京奥运会上,被国人寄予厚望,东道主的优势在舆论界宣传上,无形中被放大了许多倍,笔者研究认为目前中国女排的人员配备方面还处于摸索试验阶段,谈不上具有明显的技战术优势。坚持中国女排传统打法和以往成功的套路,作为主教练显然是不愿意轻易改变的,一方面大胆地锻炼新人、试用新的阵容组合,另一方面积极治疗伤病、恢复老队员的竞技状态,两个方面同等重要。本文就中国女排人员配备的结构,提出一些看法供专家学者共同探讨研究。  相似文献

Creativity: An essential component for effective leadership in today's schools     

Jeanie Goertz 《Roeper Review》2013,35(3):158-162

One of the most contentious areas in creativity theory is the question of domain specificity. How we conceptualize creativity — as something that transcends content domains, or as something that varies depending on the domain in question — has important implications for both creativity research and creativity training programs. The Amusement Park Theoretical (APT) model of creativity is the first creativity theory to successfully bridge the gap between these contrasting views of creativity. The APT model uses the metaphor of an amusement park to explore creativity. There are four stages: Initial requirements, general thematic areas, domains, and micro‐domains. The first level (initial requirements) is very general, and each subsequent level gets more and more domain‐specific. The APT model can provide a powerful framework for creativity assessment, selection of students for gifted education programs, and the development of creativity training programs.  相似文献   

How gay and bisexual men compensate for the lack of meaningful sex education in a socially conservative state     

Joseph M. Currin  Randolph D. Hubach  André R. Durham  Katherine E. Kavanaugh  Zachary Vineyard  Julie M. Croff 《Sex education》2017,17(6):667-681

The information shared in schools on sex education in the USA is highly variable depending on the state and sometimes city in which a student lives. Gay and bisexual students living in a socially conservative, primarily rural state such as Oklahoma often receive little information about sexual health information that pertains to their behaviours unless it is discussing the dangers of sex. Using a qualitative approach, 20 gay and bisexual men currently residing in Oklahoma completed semi-structured interviews about their experiences with sex education and alternate ways to compensate for lack of information provided. Participants noted an awareness of the lack of meaningful sex education or if it was offered, a primary focus on abstinence-only until marriage heteronormative curricula. Participants described various ways they compensated for lack of sex education including accessing pornography and information from the internet. With the current socio-political environment of Oklahoma, it is unlikely wholesale changes to the sex education curricula can be made. The importance of public health professionals using the internet and peer educators to deliver inclusive and informative sexual health information remains salient and viable for men who reside in socio-politically conservative areas like Oklahoma.  相似文献   

Impact of a universal school-based violence prevention program on violent delinquency: distinctive benefits for youth with maltreatment histories     

Crooks CV  Scott K  Ellis W  Wolfe DA 《Child abuse & neglect》2011,35(6):393-400

Objective

Child maltreatment constitutes a strong risk factor for violent delinquency in adolescence, with cumulative experiences of maltreatment creating increasingly greater risk. Our previous work demonstrated that a universal school-based violence prevention program could provide a protective impact for youth at risk for violent delinquency due to child maltreatment history. In this study we conducted a follow-up to determine if participation in a school-based violence prevention program in grade 9 continued to provide a buffering effect on engaging in acts of violent delinquency for maltreated youth, 2 years post-intervention.

Methods

Secondary analyses were conducted using data from a cluster randomized controlled trial of a comprehensive school-based violence prevention program. Students (N = 1,722; 52.8% female) from 20 schools participated in 21 75-min lessons in grade 9 health classes. Individual data (i.e., gender, child maltreatment experiences, and violent delinquency in grade 9) and school-level data (i.e., student perception of safety averaged across students in each school) were entered in a multilevel model to predict violent delinquency at the end of grade 11.

Results

Individual- and school-level factors predicting violent delinquency in grade 11 replicated previous findings from grade 9: being male, experiencing child maltreatment, being violent in grade 9, and attending a school with a lower perceived sense of safety among the entire student body increased violent delinquency. The cross-level interaction of individual maltreatment history and school-level intervention was also replicated: in non-intervention schools, youth with more maltreatment in their background were increasingly likely to engage in violent delinquency. The strength of this relationship was significantly attenuated in intervention schools.

Conclusions

Follow-up findings are consistent with the buffering effect of the prevention program previously found post-intervention for the subsample of youth with maltreatment histories.

Practice implications

A relative inexpensive school-based violence prevention program that has been shown to reduce dating violence among the whole student body also creates a protective effect for maltreated youth with respect to lowering their likelihood of engaging in violent delinquency.  相似文献
