Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.  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   

工作资源对高校图书馆员敬业度影响机制的实证研究     

康超群  杨晴 《图书情报工作》2019,63(17):69-76

[目的/意义]探讨工作资源对高校图书馆员敬业度的影响与机制，以期为高校图书馆实施人力资源管理和提升图书馆员的敬业度提供参考。[方法/过程]选取湖南各高校图书馆的358名馆员为研究对象，考察工作资源对高校图书馆员敬业度的预测作用以及心理资本与组织承诺在两者之间的中介作用。[结果/结论]描述性统计与差异分析、相关分析和逐步回归分析的结果表明，不同性别的高校图书馆员在组织承诺量表得分上存在显著性差异，男性馆员组织承诺得分显著高于女性，不同性别馆员在其余得分上均不存在显著性差异。不同婚姻、年龄、学历、职位、职称者在各量表得分上均不存在显著性差异。高校图书馆员工作资源、心理资本、组织承诺与敬业度的两两相关都达到统计显著性水平。工作资源对高校图书馆员的敬业度具有正向预测作用，心理资本和组织承诺能够在工作资源对高校图书馆员敬业度的影响中起部分中介作用。丰富高校图书馆员工作资源，增进其组织支持感，增强其心理资本和组织承诺，是促进高校图书馆员敬业度提升的有效路径。  相似文献

Using an interactive platform to recognize the intersection of social and spatial inequalities     

Lisa Poling  Travis Weiland 《Teaching Statistics》2020,42(3):108-116

With the creation of interactive tasks that allow students to explore spatial ways of knowing in conjunction with their other ways of knowing the world, we create a space where students can make sense of information as they organize these new ideas into their already existing schema. Through the use of a Common Online Data Analysis Platform (CODAP) and data from Public Use Microdata Areas (PUMA), students can explore the communities in which they live and work, critically examining opportunities and challenges within a defined space.  相似文献

张家旗  陈爽  高群  ISMAEL A. Kimirei 《中国科学院大学学报》2019,36(6):766-773

坦桑尼亚是"一带一路"倡议通向非洲、辐射非洲内陆的重要门户，它在快速城市化过程中面临交通基础设施严重短缺问题。基于坦桑尼亚公路、铁路、机场、港口、人口和城市分布数据，运用GIS空间分析技术，结合交通通达指数模型，从县域与城乡两个层面对坦桑尼亚交通通达水平的空间格局特征进行定量分析。研究发现：1）坦桑尼亚县域交通通达水平空间分布极不均衡，高值连片区主要位于东北沿海和维多利亚湖沿岸，低值连片区主要位于中央铁路线中段以北、中央铁路线南部的广大地区；2）受地理区位、资源禀赋、殖民历史、政府政策等影响，城市与乡村地区之间的交通通达水平差异十分显著。研究结果有助于坦桑尼亚制定区域交通发展政策和优化资源配置，同时对中-坦产业精准对接和产能转移具有一定的促进意义。  相似文献   

Enhancing team creative performance through social media and transactive memory system     

《International Journal of Information Management》2018

Effective teamwork, knowledge coordination, and knowledge creation are recognized as essential sources of team effectiveness and creativity in modern organizations. Nowadays, social media is significantly modifying the patterns in the use of technology to support knowledge management practices in teams. At the same time, the literature shows that transactive memory system (TMS), which refers to how team members share their distributed knowledge and expertise, is an important factor affecting team performance. However, minimal effort has been made to elaborate on the precise role of social media in supporting TMS for enhancing absorptive capacity (ACAP) and knowledge creation capability (KCC) of the team, which in turn might influence team creative performance (TCP). Therefore, to address this gap in the literature, a theoretical model is developed and validated. Survey data collected from 334 members of 68 knowledge work teams indicated that social media use at work has a positive relationship with TMS and both social media use at work and TMS are positively related to ACAP and KCC of the team. Results further indicated that ACAP positively influenced KCC, and both have a direct relationship with TCP. This study shows that careful investment in social media by an organization can enhance meta-knowledge of “who knows what” within teams. Finally, exploring external knowledge alone is not enough. Instead, organizations must ensure external knowledge is utilized to create new knowledge to improve TCP.  相似文献
