Predicting athletes’ functional and dysfunctional emotions: The role of the motivational climate and motivation regulations

This study examined the relationships between perceptions of the motivational climate, motivation regulations, and the intensity and functionality levels of athletes’ pleasant and unpleasant emotional states. Specifically, we examined the hypothesised mediational role of motivation regulations in the climate–emotion relationship. We also tested a sequence in which emotions were assumed to be predicted by the motivational climate dimensions and then served as antecedents to variability in motivation regulations. Participants (N = 494) completed a multi-section questionnaire assessing targeted variables. Structural equation modelling (SEM) revealed that a perceived task-involving climate was a positive predictor of autonomous motivation and of the impact of functional anger, and a negative predictor of the intensity of anxiety and dysfunctional anger. Autonomous motivation was a partial mediator of perceptions of a task-involving climate and the impact of functional anger. An ego-involving climate was a positive predictor of controlled motivation, and of the intensity and impact of functional anger and the intensity of dysfunctional anger. Controlled motivation partially mediated the relationship between an ego-involving climate and the intensity of dysfunctional anger. Good fit to the data also emerged for the motivational climate, emotional states, and motivation regulations sequence. Findings provide support for the consideration of hedonic tone and functionality distinctions in the assessment of athletes’ emotional states.

基于RDFS的用户本体的构建与优化研究

文章提出了一种基于本体的用户建模方法。首先,基于用户兴趣概念集合,分别从同主题源本体的RDFS闭包中抽取子本体,然后采用多策略映射方法将其合并形成初始用户本体;其次,基于各类用户Web使用数据,挖掘高频关键词,追踪用户兴趣变化,构建增量本体;然后,利用衰减函数和相关阈值,将增量本体与初始用户本体合并,在增加新概念及其关系的同时,剔除不再感兴趣的概念,以实现用户本体的自动优化。     

基于荟萃分析方法的移动商务用户采纳研究

移动商务用户采纳是信息系统领域的研究热点。综合32篇相关研究文献中的数据,采用荟萃分析方法研究感知的有用性、感知的易用性、感知的乐趣、感知的移动性、个人创新、信任、主观规范、感知的成本等因素对用户使用移动商务的态度和行为意向的影响。结果表明,感知的有用性、感知的乐趣、信任、移动性和个人创新对用户采纳移动商务有显著的正向影响,感知的成本具有显著的负向影响,感知的易用性和主观规范的影响不显著。最后,对研究结果进行讨论,并提出对策建议。

A Survey of Catalogue Use by Engineering Students in Nigerian Universities

This article is a survey of catalogue use by engineering students in Nigerian universities libraries. Simple random sampling technique was used to select one thousand three hundred and sixty-eight engineering students from three universities in the country. A questionnaire was used as the main instrument for data gathering. Some of the findings revealed that a majority of the student survey participants make use of the catalogue occasionally and prefer to browse through the shelves when searching for information in the libraries. This article recommends that library use instruction should be included in the university curriculum and that librarians should provide practical demonstrations on the use of various catalogues to students during orientation programs.
