基于协同创新的地方高校研究生培养模式

当前我国研究生培养中出现了协同创新教育理念未达成共识、研究生培养目标与社会需求偏差、校内外条块分割局面未完全打破、协同创新的研究生培养机制尚未健全等问题,提出基于协同创新的地方高校研究生培养必须树立研究生教育协同创新理念、厘清各创新主体利益诉求、协同打造联合培养利益共同体、建立健全协同创新运行机制、探索协同培养研究生模式,保障研究生教育健康持续发展等策略。

Branding of Flemish higher education institutions: a strategic balance perspective

Branding of higher education institutions (HEIs) is an expanding area of research. The existing literature mainly draws on the strategic management perspective that argues that HEIs are pressured to develop brands which differentiate them from their competitors. Past studies, however, do insufficiently take into account that most HEIs are positioned in systems that contain both competitive pressures (to differentiate) and institutional pressures (to meet taken-for-granted expectations), where neither of the pressures is clearly dominant. Our multiple case study of the five Flemish universities finds that branding can simultaneously address competitive and institutional pressures and that the universities studied combine aspects of distinctiveness with elements of similarity.     

自然保护区周边社区薪柴消费影响因素分析

薪柴作为一种传统能源,依然是自然保护区周边社区的主要生活能源。落后的薪柴采集和消费不仅造成能源浪费,还严重影响着自然保护区的资源生态环境,因此促进自然保护区周边社区的薪柴消费向高效清洁的商品能源消费转变具有重要意义。本研究基于陕西省洋县和宁陕县朱鹮自然保护区周边社区农户薪柴消费微观调查数据,采用多元线性回归模型,对自然保护区周边家庭薪柴消费的影响因素进行了计量分析。结果表明,0.01的显著水平上,家庭人口数、家庭年龄、养殖业收入对农户薪柴消费具有显著正向影响,外出务工收入对农户薪柴消费具有显著反向影响;在0.05的显著水平上,个体经营收入对农户薪柴消费具有显著反向影响。因此,通过提高农民的教育水平,引导农村剩余劳动力进城务工,加强自然保护区转移支付等方式,促进自然保护区周边能源消费从薪柴消费向商品能源消费转变,是解决自然保护区周边社区森林资源破坏的有效途径。

面向“卡脖子”问题的知识创新生态系统分析：核心挑战、理论构建与现实路径

  新形势下,面对关键核心技术“卡脖子”问题的挑战,系统提升我国科技研究的整体水平迫在眉睫。然而,我国现有知识创新生态研究的基本思路仍是以“大学、企业、政府”构成的“三螺旋”框架,无法体现新时代多元化主体、多样化路径、多种创新模式的平行共存与协同演化特征,致使研究者破题“卡脖子”难题时缺乏整合性视角与适用性框架的支撑。本研究基于知识创新范式转型背景下影响我国以系统工具解决“卡脖子”问题的核心挑战,深入探究新时代“模式3”知识创新“多重螺旋”（N-tuple helices）生态系统的主体特征与拓扑结构。以之为基础,讨论系统性提升我国科研创新能力,应对“卡脖子”挑战的可行路径与具体措施。

Relationships between anthropometric measures and athletic performance,with special reference to repeated-sprint ability,in the Qatar national soccer team

Abstract

The aim of this study was to determine potential relationships between anthropometric parameters and athletic performance with special consideration to repeated-sprint ability (RSA). Sixteen players of the senior male Qatar national soccer team performed a series of anthropometric and physical tests including countermovement jumps without (CMJ) and with free arms (CMJwA), straight-line 20 m sprint, RSA (6 × 35 m with 10 s recovery) and incremental field test. Significant (P < 0.05) relationships occurred between muscle-to-bone ratio and both CMJs height (r ranging from 0.56 to 0.69) as well as with all RSA-related variables (r < –0.53 for sprinting times and r = 0.54 for maximal sprinting speed) with the exception of the sprint decrement score (S_dec). The sum of six skinfolds and adipose mass index were largely correlated with S_dec (r = 0.68, P < 0.01 and r = 0.55, P < 0.05, respectively) but not with total time (TT, r = 0.44 and 0.33, P > 0.05, respectively) or any standard athletic tests. Multiple regression analyses indicated that muscular cross-sectional area for mid-thigh, adipose index, straight-line 20 m time, maximal sprinting speed and CMJwA are the strongest predictors of S_dec (r² = 0.89) and TT (r² = 0.95) during our RSA test. In the Qatar national soccer team, players’ power-related qualities and RSA are associated with a high muscular profile and a low adiposity. This supports the relevance of explosive power for the soccer players and the larger importance of neuromuscular qualities determining the RSA.
