“双一流”目标下一流大学科研效率评价

“双一流”建设是我国高等教育强国建设的战略安排,是我国高等教育发展的必由之路。“双一流”建设之一流大学建设高校,是高等教育强国建设的“领头雁”,研究一流大学建设高校科研创新效率,加快提升科学研究水平具有重大现实意义。本文以一流大学高校为研究对象,构建了突出科研产出质量和服务的综合效率评价指标体系,在传统DEA模型基础上运用随机前沿分析理论,通过三阶段DEA模型方法测度一流大学建设高校的科研效率,并进一步分析环境因素对科研效率的影响差异。研究结果表明：(1)环境变量和随机误差是影响一流大学科研效率的重要因素,我国一流大学整体科研效率存在虚高现象,剔除环境因素后样本高校综合效率和纯技术效率均值都明显下降。(2)地区经济水平、居民受教育程度和政府扶持力度对各个高校科研效率存在差异性影响,并据此将高校分为稳定型、发展型和改进型三类。(3)一流大学建设高校科研效率存在分化倾向,规模收益递减现象突出,其科研效率提升的关键是缩减规模、完善内部治理结构、优化资源配置,持续深化科研体系改革。     

Kicking modality during erratic-dynamic and static condition effects the muscular co-activation of attacker

The purpose of the study was to investigate the effect of different kicking modality, i.e., erratic-dynamic target (EDT) versus static target (ST) on the performance of the roundhouse kick in two groups of taekwondo athletes of different skill level. Three-dimensional analysis and surface electromyography (SEMG) analysis were performed on 12 (Group A: six sub-elite, Group B: six elite) athletes to investigate muscle co-activation pattern under two conditions, i.e., EDT versus ST. In the results, the muscle recruitment ratio of the agonistic muscles was higher for Group A, whereas Group B had higher recruitment ratio for antagonist muscles. Overall, the co-activation index (CI) of hip joints appeared higher in the extensors for Group A, whereas higher CI was observed in flexor muscles for Group B with comparatively higher CI during EDT condition than ST condition. Higher value of CI was observed in flexor muscles of the knee joints among Group A during EDT conditions, in contrast, higher CI in the extensor muscles was observed among Group B during ST conditions. In conclusion, the study confirmed that erratic-dynamic movements of target could change the movement coordination pattern to maintain the joint stability of participants.     

沈家本的刑事审判法思想初探

作为清末法学大家,沈家本有着较为丰富的刑事审判法思想。他主张仿效西方,在我国构建专门的审判机关体系,设立陪审制度,废除法堂刑讯,并呼吁对审判官进行职业教育和严格选拔。沈家本的学术思想和修律实践有力地推动了中国刑事审判的近代化进程。     

电子期刊与纸质期刊对比分析研究

电子期刊是高校图书馆的新型信息资源,在教学科研工作中起着越来越大的作用.但目前各图书馆都存在电子期刊与纸质期刊重复收藏现象.如何正确处理好二者的相互关系.使有限的经费发挥出最大的效能,是一个值得深入研究的问题.以华北电力大学图书馆外文纸质期刊与电子期刊的收藏情况为样本,逐一进行了对比分析,进而提出了几点协调两者关系的设想.

Bilingual PA and its influence on biliteracy for Korean English as a foreign language learners

This study examines the relationship between phonological awareness (PA) in the two languages of Korean English as a foreign language learning children in relation to L1 characteristics and school experiences, and its predictive role in word decoding skills in each language. Seventy-two 5?C6-year-old Korean children who had attended English-medium preschools and kindergartens for at least 18?months were tested on a range of PA and emergent literacy skill measures in both Korean (L1) and English (L2). The findings indicate that the phonological representations of the participants reflect more of the L1, rather than school language, characteristics. In addition, L1 PA, syllable and phoneme awareness in particular, was predictive of L2 decoding abilities after accounting for L2 PA and emergent literacy skills. The results are discussed in terms of language-specific L1 phonological and orthographic characteristics, as well as their L2-learning contexts.
