This study examined the extent to which 2 x 2 achievement goal constructs (Elliot, 1999) were associated with key relational perceptions (i.e., relationship commitment, relationship satisfaction) for members of athlete-athlete dyads. Both members from 82 regional-level partnerships (mean age = 22.72, SD = 3.83) were recruited from a variety of dyadic sports (e.g., tennis, badminton, rowing). Actor-partner interdependence model analyses revealed that greater dissimilarity between partners on mastery-approach and performance-approach goals was associated with lower commitment and satisfaction. Mastery goals displayed positive actor effects with respect to both relationship perceptions, whereas performance-avoidance goals were negatively related to commitment (i.e., actor and partner effects) and satisfaction (i.e., partner effect). These results indicate that achievement goal constructs may align with important interpersonal perceptions in athlete dyads. 相似文献

The amount of heterogeneous data that is available to organizations nowadays has made information management a seriously complicated task, yet crucial since this data can be a valuable asset for business intelligence. Ontologies can act as a semantically rich knowledge base in systems that specialize in information management. The present work investigates the potential of ontologies in supporting the information lifecycle within a corporate environment for business intelligence. The paper demonstrates the use of Heraclitus II, a framework that employs ontology management and evolution in the context of information management systems. The capabilities of the framework in facilitating information management and business intelligence are evaluated through a real-life case study from the life sciences industry. 相似文献

Students training to become teachers of science to children aged between 7 to 11 years used principles of reflective practice linked to participatory approaches in their curriculum planning and evaluation. A central part of the work was to enable them to introduce aspects of education for sustainability to their pupils. Students first undertook a process of clarifying their ideas and concerns about education for sustainability. They went on to develop aims that should help them to achieve a series of objectives that they identified. Teaching schemes were created and trialled in the classroom. A semi‐quantitative evaluation instrument was devised based on the objectives that had been set, allowing judgements to be made about the effectiveness of the teaching approaches used. 相似文献

许多教练员面临这样的困惑:有的运动员训练成绩突出,可比赛成绩平平;而有的运动员虽训练表现一般,但比赛成绩非常突出.这种情况的出现,在集体项目中,会增加教练员的选材困难:在个人项目中,会引起运动员对比赛的消极态度. 相似文献
