Methods for assessing higher education research team collaboration: comparing research outputs and participant perceptions across four collaborative research teams     

Nick Kelly  Joanne Doyle  Marisa Parker 《高等教育研究与发展》2020,39(2):215-229

ABSTRACT

This article suggests that situations in which multiple research teams are convened under similar conditions present an opportunity to discover factors that lead to productive collaboration. It argues that social network analysis of research team outputs becomes more valuable when paired with data about research participant perceptions; and that any variables used as indicators of collaboration need to be calibrated using datasets from multiple studies with cross-team comparisons. The article provides an example of the kind of methodology needed to achieve this, describing a study with data from four research teams based at an Australian university campus, reporting their research performance over four years under conditions in which many variables were controlled and with results augmented by a survey of participant perceptions. Findings from the study indicate that there were exceptions to hypothesized associations between participant perceptions of collaboration and specific social network analysis measures over co-authorship data. The article suggests that, given the methodological challenges of studying research teams in the field, multiple datasets combining findings such as those in the present study are a path towards the development of indicators of productive higher education research collaboration.  相似文献

Development and Reliability of the Comprehensive Crisis Plan Checklist, 2nd Edition     

Daniel F. McCleary  Kathleen B. Aspiranti 《Psychology in the schools》2020,57(7):1155-1170

As the research base for school crisis intervention and prevention expands, the need for well-developed tools to assess school readiness in the event of a crisis increases. This paper describes how the Comprehensive Crisis Plan Checklist (CCPC) was updated to reflect advances in crisis management and crisis planning. An extensive literature search and pilot study were used to refine existing items and create new items for the checklist. The Comprehensive Crisis Plan Checklist, 2^nd Edition (CCPC-2) has 102 items separated into three sections: prevention, intervention, and postvention. The CCPC-2 can be used by crisis teams to create new crisis plans or evaluate existing ones. Users are encouraged to carefully consider the inclusion of all items and articulate why individual items are not necessarily based on their specific needs. The CCPC-2 was given to 10 pairs of raters to evaluate school-based crisis plans; average interrater reliability was 89.04%. Discussion focuses on item analysis and how to use the checklist within a school setting.  相似文献   

Efficacy of using non-linear pedagogy to support attacking players’ individual learning objectives in elite-youth football: A randomised cross-over trial     

Simon J. Roberts  James R. Rudd  Matthew J. Reeves 《Journal of sports sciences》2020,38(11-12):1454-1464

ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献   

员工建言行为对团队创造力的作用机制          下载免费PDF全文

邓今朝喻梦琴丁栩平 《科研管理》2018,39(12):171-178

采用现场调查方法，以湖南、湖北、福建、广东和浙江等地企事业单位614名员工、93个不同职能的工作团队为研究对象，分析探讨了员工建言行为对团队创造力的影响及其内在的认知作用机制。研究结果表明：员工建言行为对团队创造力有显著的正向影响，交互记忆系统中的专长和信任维度采用现场调查方法，以湘、鄂、闽、粤和浙等地企事业单位614名员工、93个团队为对象，应用多元回归方法探讨了员工建言对团队创造力的影响。研究发现：员工建言对团队创造力有显著的影响，交互记忆系统中的专长和信任维度在员工建言与团队创造力之间有部分中介作用，而知识共享则有完全中介效应，团队学习行为在员工建言对团队创造力作用中有正向调节效应。在两条作用路径中，团队学习行为越高，员工建言对交互记忆系统（知识共享）的积极作用越大，进而对团队创造力的影响越强。  相似文献   

内部社会资本、二元学习与研发团队创造力          下载免费PDF全文

戴万亮  杨皎平  李庆满 《科研管理》2019,40(1):159-169

团队成员工作积极性不高与创造力不够是阻碍研发团队创新的最大问题，良好关系下的团队成员知识交流与思维碰撞对于研发团队创造力至关重要。以二元学习为中介变量，知识异质性为调节变量，构建了内部社会资本影响研发团队创造力的有调节的中介效应模型。采用结构方程模型，基于308个研发团队的数据的实证研究发现：结构资本和认知资本对研发团队创造力的直接影响显著，而关系资本对研发团队创造力的直接影响不显著；二元学习在结构资本及认知资本与研发团队创造力的关系中扮演部分中介角色，而在关系资本与研发团队创造力的关系中扮演完全中介角色；知识异质性正向调节二元学习中介效应。本研究有助于加强对团队创造力影响因素及作用机理的了解，也为提高研发团队创造力提供借鉴。  相似文献

The effect of beetroot juice supplementation on repeat-sprint performance in hypoxia     

Georgina L. Kent  Brian Dawson  Lars R. McNaughton  Gregory R. Cox  Louise M. Burke  Peter Peeling 《Journal of sports sciences》2019,37(3):339-346

This investigation assessed the effect of dietary nitrate (NO₃^?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO_2peak 53.1 ± 8.7 mL.kg^?1.min^?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYP_BR; 13 mmol NO₃^?) or NO₃^–depleted BR placebo (HYP_PLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO₂) was measured during the warm-up. There were no significant differences observed between HYP_BR and HYP_PLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYP_BR compared with HYP_PLA. There was a moderate effect for VO₂ to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO₃^? may not improve repeat-sprint performance in hypoxia but may reduce VO₂ during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise.  相似文献   

回顾与前瞻: 中国男子篮球职业联赛竞争格局演变特征     

蒋志伟  邱希 《武汉体育学院学报》2019,53(2):89-95

运用ABC分析法对1995-18赛季CBA比赛进行分析，探析CBA竞争格局的演变特征和演变规律。参照CBA各球队竞争实力变化特点，遵循事物发展的规律，将CBA的发展过程划分为4个阶段，追溯各阶段竞争格局的特点，以此归结CBA竞争格局的演变特征，认为：CBA在经历传统强队的滑坡与新兴球队的兴起后，竞争格局发展趋向更加难以预测；竞争格局在经历北强南弱、南强北弱后，正向更加均衡的态势发展；东、西部区域发展不均衡。  相似文献
