论校对功能的变化与提升

把校对功能问题放在历史的层面上去考察,就不难发现,20世纪80年代以前,校对的功能主要是“校异同”。随着计算机网络技术的普及,激光照排技术的应用,校对功能发生了深刻变化,从主要“校异同”提升为主要“校是非”。

《毛诗序》和《诗品序》文学观念的浅略比较

《毛诗序》和《诗品序》都是我国古代诗论的专著,在“诗的国度”的我国长期的诗歌创作和评论中,都产生过久远深厚的影响。它们问世的时间有先有后,但在文学观念上却不能视为“衣钵相承”之作。本文从四个方面评价和比较了它们的文学观念。

唐传奇"史才"考论

唐传奇作者之"史才"不等同于历史学意义上的史学才能,却又与史学联系密切。从唐代史官制度与文学之关系的角度来考察,小说家"史才"当从"假小说以寄笔端"中求取,其实质包孕史学传承、历史意识生成、历史笔法借鉴等涵义。     

The different faces of controlling teaching: implications of a distinction between externally and internally controlling teaching for students’ motivation in physical education

Background: In Self-Determination Theory (SDT), a well-validated macro-theory on human motivation, a distinction is made between internally controlling teaching practices (e.g. guilt-induction and shaming) and externally controlling practices (e.g. threats and punishments, commands). While both practices are said to undermine students’ motivation, they would do so through somewhat differential motivational processes. Unfortunately, the relevance of the conceptual distinction between internally and externally controlling strategies has not been examined systematically. In the context of sport and physical education (PE), most studies on controlling teaching have either measured controlling teaching in an undifferentiated way or have focused on one particular feature of controlling teaching.

Purpose: The purpose of this study was to provide a more fine-grained picture on the differential de-motivational effects of internally and externally controlling teaching strategies in the domain of PE.

Participants: A total of 925 students with an average age of 15.80 years (±1.99) coming out of 92 classes taught by 22 different PE teachers participated in the present study.

Data analysis: Data on perceived controlling teaching style and students’ motivation were analyzed within a multilevel framework from both a variable-centered (regression analyses) and person-centered approach (cluster analyses).

Results: We found evidence for a distinction between perceived internally and externally controlling teaching. Both teaching styles were strongly related to each other (r?=?.54). At the level of zero-order correlations, both internally and externally controlling teaching related negatively to students’ intrinsic motivation and identified regulation and related positively to introjected regulation, external regulation, and amotivation. However, when both teaching styles were included simultaneously as predictors of motivation in the regression analyses, only internally controlling teaching predicted poor quality and low quantity of motivation. A cluster analysis revealed different profiles of perceived controlling teaching style, with two profiles being characterized by either high or low levels of the two types of controlling teaching and other profiles displaying elevated or reduced levels of one of the types of controlling teaching. This person-centered analysis confirmed that particularly students who perceive their PE teacher as internally controlling are likely to report poor-quality motivation.

Conclusion: Controlling teaching (and internally controlling teaching in particular) is related to maladaptive motivational outcomes. As such, it can be advised to PE-practitioners to refrain from using controlling strategies when teaching students. More research is needed to identify the conditions under which teachers’ behavior is perceived as externally and/or internally controlling.     

现代竞技体育体能训练对改善女大学生脊柱功能的研究

脊柱功能是衡量人体健康水平的重要指标,对人体保持高质量的学习、生活和工作状态产生直接的影响。如何运用有效的训练改善和提高人体脊柱功能,应引起高度的重视。以黑龙江省30名女大学生为研究对象,制定有针对性的训练方案,进行为期3个月的运动干预实验,分5个阶段进行训练监控及训练效果评估。结果显示：全体受试对象脊柱直背趋势最为显著,脊柱姿势、柔韧性、稳定性整体较差,脊柱疾病风险较高;通过动态拉伸、颈肩及腰等功能性训练对改善女大学生脊柱功能效果显著;实施训练方案后,在第30天改善效果最为明显。     

中国皮划艇国家二队功能动作筛查的应用研究

运用文献资料法、测试法、问卷调查法、专家访谈法和数理统计法对国家皮划艇青年队进行功能动作筛查测试,根据测试结果为备战2020年奥运会提供数据及理论的支持。通过研究发现:划艇运动员的总分情况整体优于皮艇运动员;大部分运动员髋、膝、踝三关节在单一的运动平面中具有较好的协调和稳定性,但在两个以上的运动平面中完成动作的稳定和控制能力有待提高;运动员的髋关节、肩关节及股四头肌柔韧性存在不平衡现象,左侧链与右侧链在多运动平面中协调稳定性也存在不平衡现象;运动员的损伤率较高,且损伤的主要部位是肩和腰。
