高校人才集聚绩效评价方法探析:集聚指数的编制与应用

优秀人才的集聚是高校核心竞争力提升的首要前提,而如何考量高校人才集聚的绩效成为亟待解决的难题。本研究运用统计指数相关方法编制了高校人才集聚指数作为绩效评价的一种方法,并进一步选择位于东北、西北、中部、东部和东南的5所“985”高校,对其2000年以来人才集聚指数进行测算,通过分析测算结果发现五所高校的人才流动均呈逐步优化的发展态势,且发展态势相对稳健,但高校间人才集聚绩效存在一定差异,而差异幅度在一段时间内表现得相对稳定。

Twenty years of research on total quality management in Higher Education: A systematic literature review

Faced with intensified global education competition, universities and other Higher Education institutions are implementing Total Quality Management (TQM) to keep rivals at bay. Meanwhile, research interest in TQM in Higher Education is growing. This paper reviews the achievements and limitations of extant research on TQM in Higher Education, and discusses directions for future research. The paper finds that extant research focuses on (1) teaching and learning but neglects research and industry engagement; (2) an isolated factor (e.g., teacher) but neglects other factors (e.g., facilities); (3) the Higher Education sector in advanced countries but neglects the Higher Education sector in developing countries; and (4) TQM as a phenomenon but neglects theory development and integration. Future research needs to address these limitations, adopt a more holistic perspective, and take a more inclusive and comprehensive approach to TQM in the Higher Education sector.     

Simultaneous changes in seed size,oil content and protein content driven by selection of SWEET homologues during soybean domestication

Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed. Soybean domestication involved parallel increases in seed size and oil content, and a concomitant decrease in protein content. However, science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes. Here, re-sequencing data from >800 genotypes revealed a strong selection during soybean domestication on GmSWEET10a. The selection of GmSWEET10a conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content. The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans. Moreover, GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding. Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean. We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.

从第13、14届世界健美操锦标赛成绩看竞技健美操竞争格局与发展态势

采用文献资料法、录像观察法和比较分析法对第13、14届世界健美操锦标赛成绩进行对比分析,并结合2013-2016年周期新规则,探究世界竞技健美操竞争格局和发展态势,为中国竞技健美操进一步发展提供可借鉴的理论依据。研究认为:竞赛规则指引着竞技健美操发展方向,对新规则的理解和掌握直接影响着比赛成绩;世界竞技健美操保持欧亚大陆雌雄争夺、美洲势单力薄的"偏"三足鼎立竞争格局;亚洲国家总奖牌数和金银铜牌数追平乃至超越欧洲国家,强烈冲击欧洲国家长久统治的主宰地位;中国竞技健美操在经历低谷后焕发崭新生机,重新进入国际领军集团;世界竞技健美操呈现国际化发展的确定性和洲际、国家强弱流动的不确定性互相交织的态势发展。
