Talent identification and selection in elite youth football: An Australian context

We identified the perceptual–cognitive skills and player history variables that differentiate players selected or not selected into an elite youth football (i.e. soccer) programme in Australia. A sample of elite youth male football players (n?=?127) completed an adapted participation history questionnaire and video-based assessments of perceptual–cognitive skills. Following data collection, 22 of these players were offered a full-time scholarship for enrolment at an elite player residential programme. Participants selected for the scholarship programme recorded superior performance on the combined perceptual–cognitive skills tests compared to the non-selected group. There were no significant between group differences on the player history variables. Stepwise discriminant function analysis identified four predictor variables that resulted in the best categorization of selected and non-selected players (i.e. recent match-play performance, region, number of other sports participated, combined perceptual–cognitive performance). The effectiveness of the discriminant function is reflected by 93.7% of players being correctly classified, with the four variables accounting for 57.6% of the variance. Our discriminating model for selection may provide a greater understanding of the factors that influence elite youth talent selection and identification.

军民融合创新研究综述与展望

坚定不移地走军民融合创新之路，在更广范围、更高层次、更深程度上把国防科技创新体系纳入国家创新体系之中，不仅是新时代中国特色社会主义发展之战略考量，更是科技发展自身之客观规律的重要体现。以2003-2019年间中国知网军民融合创新相关核心文献为研究样本，绘制该研究领域知识图谱，探究发现：目前核心研究力量主要集中在国防特色高校和军事院校，机构之间缺乏密切的合作与交流，尚未形成成熟的研究网络；现有研究依然以情报分析为主，统计分析、前沿面分析以及系统分析方法应用较少；研究热点逐步体现出更加微观和具体的特点。未来该领域研究应坚持以习近平军民融合发展战略思想为指导，站在国际国内的战略高度，不断扩充研究领域与参与机构，强化研究网络合作的广度和深度；立足于中国特色的管理实践，加强案例研究，完善高质量企业层面数据平台的建立，丰富多维度、多领域、多学科交叉研究方法的使用，深化科技发展内在规律等微观机理层面的研究，进一步完善军民融合创新科技平台的建设，为基于军民一体化的国家科技计划提供有效的智库支持。

What makes learners a good fit for hybrid learning? Learning competences as predictors of experience and satisfaction in hybrid learning space

Compared with fully face-to-face or online learning environments, implementation of hybrid learning spaces is costly given the spaces making all learning options available for learners. Therefore, decisions on investments in hybrid learning are critical for institutions. Satisfaction and experience of learners is one of the important indicators for assessing the cost-effectiveness of learning space implementation; thus, predictions of learners' satisfaction and experience can inform institutions' decision making on learning space investments. Moreover, learning competences are found correlated with learners' satisfaction and experience in general and e-learning settings. Therefore, the present study aimed at exploring predictive learning competences for hybrid learners' experience and satisfaction. A hybrid learning space was built upon a proposed model at Shanghai Open University. 211 students’ learning competences and their satisfaction and experience in the hybrid learning space were examined. The results showed that except cognitive engagement competence, most predictive competences were not significantly associated with hybrid learners' satisfaction and experience. The findings indicated that since hybrid learning keeps all options available, to experience satisfying learning, students need not have certain competences but cognitive engagement competence, which is correlated with learners' cognitive ability to figure out the right mix of learning options.
