Classroom teachers and physical activity integration

This project examined 23 teachers’ involvement in a curricular project to integrate physical activity into the school day. The teachers represented all grade levels and worked in schools that served Native American students in the United States. Interviews occurred twice during the year-long project. Data were analyzed via constant comparison. Teachers’ willingness to engage was influenced positively by caring about students and their own personal wellness history. Their engagement was impeded by institutional factors of scheduling and assessment pressures. The results provide insights into how teachers might be persuaded to and prepared for the implementation of similar programs in new locations.     

明末清初皖江作家活动年表

明末清初是皖江作家群形成与发展期。这一时期,桐城、宣城和池州作家群形成并活跃于当时的文坛,由于地缘的关系,三地作家有着广泛而深入的联系,从而形成了更大规模的皖江作家群。但由于基础性研究工作的不足,致使这一地域的作家研究总是以个案的形态呈现。编写作家活动年表,或许可以为这一地域的作家群体研究提供更多的线索,加快推进对皖江文化的形成与发展的规律的探索。     

Investigating children's musical interactions within the activities systems of group composing and arranging: An application of Engeström's Activity Theory

This article applies Engeström's Activity Theory (AT) as an analytical lens to identify defining characteristics of the collaborative creative music making activities of composing and arranging. Attention is paid to the complex interrelationships among the various elements of interaction in children's collaborative creative music making as evidenced in group composing (where the activity features generation and revision of new musical material) and arranging (where the activity features creative use of existing musical material) are differentiated tasks. These include, for example, tool use in response to different tasks, the rules that govern peer collaboration, and the division of labour experienced among key players in the co-construction of decisions. Exemplary cases are sampled from data sets drawn from two separate sites one of which features a group composing task with fifth graders in a USA urban school and the other a group arranging task with eighth graders in a UK urban school. This micro-analysis is less concerned with the differences of collaborative interaction in varying cultural settings than with exploring the micro-analysis of social and language processes that characterise these differentiated creative tasks and the related activity systems. The activity system, or systems of social relations, is the unit of analysis applied across comparison-group cases using ethnographic observation, and discourse and event analysis. Analysis of the data indicates that composing and arranging involve differentiated activity systems. Important defining characteristics of the collaborative interactions, as outcomes of the children's approach to the task activities, are identified. Conclusions indicate that the application of an activity theory research perspective can provide a useful framework to make sense of the interrelated elements that characterise interaction in peer collaboration.

成本性态的新理念--作业成本法

中国已经加入了WTO,这对中国的经济来说既是机会也是挑战,随着全球经济一体化和国际会计协调化,原始的成本性态分析已经跟不上经济的飞速发展及要求。简单的成本分析对战略管理要求和成本控制都有局限性,并且不利于最有效的产品生产决策,所以我们要转变成本的计算方法,从而达到控制成本、正确评价作业中心及相关部门业绩的目的．我国应尽快适应成本性态的新理念,以适应现实复杂的环境,保证财务会计的真实性,使经济环境健康发展。     

网络游戏对大学生参与体育锻炼的影响

文章采用问卷调查法、访谈法对泉州医学高等专科学校学生玩网格游戏和课外体育锻炼的情况进行调查,分析网络游戏对学生参与课外体育锻炼的影响及原因,并提出建议,为我校今后进行学生管理及发展学生体育的决策提供参考。调查表明：学生玩网络游戏的比率高,玩的时间比较长,而参与课外体育锻炼的人数比率小,锻炼项目集中,锻炼次数少。经常玩网络游戏的学生参与锻炼的次数和时间都低于平均值。

对武汉市儿童体育锻炼的调查与分析

本文通过文献资料法、访谈法、问卷调查法、数理统计法等研究方法,对武汉市儿童体育锻炼的现状进行了调查和研究。结果显示：沉重的学习压力影响了儿童体育锻炼的时间、活动项目,降低了活动兴趣;男生和女生最喜欢的项目是羽毛球和跳绳,但同时也受校园体育锻炼、体育课教学内容及玩伴的影响;现阶段体育设施相对缺乏,场馆管理混乱也成为儿童参与体育锻炼的阻碍。针对存在的问题提出相应的对策,旨在提高儿童的身体素质。

骨关节活力操练习对青年白领柔韧性影响的研究

目的:探索骨关节活力操对青年白领柔韧性的影响和作用,为大众健身提供理论依据。方法:随机招募60名20-39岁青年白领接受12周,每周3次,每次45分钟的骨关节活力操练习,12周训练前后分别进行关节活动度、转肩握距、俯卧背伸、坐位体前屈等柔韧性指标的测试。结果:1.骨关节活力操练习可以显著增加青年白领肩关节伸展、内收活动度。2.骨关节活力操练习可以显著改善青年白领髋关节伸展、外展活动度。3.骨关节活力操练习可以显著改善青年白领踝关节背屈活动度。4.骨关节活力操练习对青年白领转肩握距、俯卧背伸、坐位体前屈均有良好的促进作用。结论:骨关节活力操融入了日常生活的身体功能训练,可以有效改善青年白领柔韧性,对于保持关节活动度,对抗因增龄和活动减少带来的柔韧性下降,有非常良好的效果,可以降低静坐少动以及不良身体姿势带来的身体隐性损害,是白领全民健身的良好选择。
