对运动员竞技能力非衡结构补偿理论的几点思考

运动员竞技能力非衡结构补偿理论与“积木模型”的创建实现了竞技能力系统结构与功能的统一,在训练实践中正在作为一种指导性理论得到推行。作者对该理论提出了几点思考,认为：一般模型不能满足运动员竞技能力个性化发展的要求,而竞技能力非衡结构个体模型的建立存在构建原理与方法上的困难;运动员竞技能力非衡结构稳定性在内外可控与不可控因素的作用下只存在于某一阶段;部分运动员的竞技能力非衡结构会因敏感要素的相同或类似表现出群类特征。

对广东省游泳运动员退役年龄结构的研究

运用文献资料调研、数理统计及比较分析等方法对广东省游泳退役运动员的年龄结构进行研究，结果表明，广东省游泳运动员退役年龄明显偏小，在延长运动寿命方面仍有一定潜力可挖。     

对河南省体育健身娱乐市场消费群体现状的调查分析

运用社会学研究方法对河南省郑州、开封、洛阳3市体育健身娱乐市场消费群体的消费行为、消费动机、消费结构以及消费形式进行了调查。结果表明：其消费结构女性比例超过男性,主要分布在20至35岁之间;消费动机主要是健身健美、减肥治病;消费形式主要在收费中等偏下的体育娱乐场所;消费行为有70％以上消费者有相对固定的消费场所,并认可市场价格。总体对比目前处于国内平均水平。

Karol Estreicher (1827–1908) and his Bibliografia polska: Negotiating a National Bibliography in Nineteenth-Century Poland

Karol Estreicher (1827–1908) compiled Bibliografia polska [Polish bibliography], an extraordinary retrospective national bibliography of the body of written works of Poland. Chronologically covering the entire history of printing in Poland up to 1900, it consisted of three distinct parts: the nineteenth century; a universal chronological bibliography of Polish publications; and pre-nineteenth century, conventionally called Bibliografia staropolska [Bibliography of old Poland]. So far a total of 56 volumes of Bibliografia polska have been published. That total includes the 35 volumes that constitute parts 1, 2, and 3; the four volumes that, covering 1891–1900, were published outside the framework of the three parts; and the seventeen volumes that constitute the second edition of part 1, the nineteenth-century bibliography. It was an exhaustive but also complicated bibliographic opus. A prolific writer and literary scholar himself, Estreicher devoted—with remarkable endurance and resilience—50 years of his life to its making. Much of the complexity of his bibliography reflected the cultural and intellectual roots of the author and the way he interpreted the meaning of his project.     

Institutional Isomorphism and the Community Structure Approach in Visual Framing of the Trayvon Martin Shooting

Institutional isomorphism and the community structure approach present two very different editorial decision-making processes, which could potentially lead to very different news products. This study tested hypotheses related to the two approaches within visual framing of the Trayvon Martin shooting. Images used by two elite national newspapers and three newspapers from racially distinct communities were compared. Evidence of normative isomorphism was found, though it was unclear if intermedia agenda setting by elite publications was responsible. Hypotheses predicting different visual framing among different community structures were not supported. Theoretical implications for considering intermedia agenda setting under the institutional isomorphism framework are discussed.     

CONTENTdm Digital Collection Management Software and End-User Efficacy

ABSTRACT

Digital libraries and collections are a growing facet of today's traditional library. Digital library technologies have become increasingly more sophisticated in the effort to provide more and better access to the collections they contain. The evaluation of the usability of these technologies has not kept pace with technological developments, however, and the end-user has in some cases been left behind. This research study evaluates the usability of digital collections created using the CONTENTdm Digital Collection Management System, a software system used by the University of North Carolina at Chapel Hill. Specifically, this study addresses the following questions: Does CONTENTdm meet users' needs? Is the interface sufficiently intuitive for them to use it? Is the experience of exploring digital collections using CONTENTdm satisfying to users? Employing usability testing techniques with actual-end users, this study attempts to assess the efficacy of the CONTENTdm public interface as well as user attitudes toward it. Ten participants from three user groups—faculty, library science graduate students, and the general public—performed eleven tasks designed to test the key functions of CONTENTdm-created collections and then answered a series of questions about their experiences. Key findings from this study indicate that while the included digital collections are useful and desirable to end-users, the interface generated by CONTENTdm can be confusing even for those who have considerable experience using the Internet. Results from this study may be used to improve this software system and add to the literature surrounding the usability of digital libraries in general.
