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.

不同天气条件下古尔班通古特沙漠南缘梭梭(Haloxylon ammodendron)群落能量通量日变化特征

基于2018年夏季在古尔班通古特沙漠南缘采用波文比系统实测的气象及能量资料,分析该区不同天气条件下梭梭群落能量特征及能量分配的日变化特征。结果表明：1） 该区夏季晴天和多云天各能量曲线变化趋势基本一致,呈单峰型,土壤热通量最小,晴天和多云天感热略高于潜热;阴天能量传输以感热为主;雨天整体热通量最小,且各能量曲线呈多峰形变化,能量传输以潜热为主。2） 白天,波文比值雨天最小,且小于1,晴天、多云天、阴天依次增大,且大于1;夜间,晴天、阴天、多云天、雨天的波文比值依次增大,均小于1。3） 不同天气条件下能量分配曲线白天变化平稳,夜间波动显著,日出和日落前后波动最为剧烈;因不同天气条件下辐射强度和日照时数的不同,曲线早、晚剧烈变化开始时间有所不同。     

How students reason about matter flows and accumulations in complex biological phenomena: An emerging learning progression for mass balance

In recent years, there has been a strong push to transform STEM education at K-12 and collegiate levels to help students learn to think like scientists. One aspect of this transformation involves redesigning instruction and curricula around fundamental scientific ideas that serve as conceptual scaffolds students can use to build cohesive knowledge structures. In this study, we investigated how students use mass balance reasoning as a conceptual scaffold to gain a deeper understanding of how matter moves through biological systems. Our aim was to lay the groundwork for a mass balance learning progression in physiology. We drew on a general models framework from biology and a covariational reasoning framework from math education to interpret students' mass balance ideas. We used a constant comparative method to identify students' reasoning patterns from 73 interviews conducted with undergraduate biology students. We helped validate the reasoning patterns identified with >8000 written responses collected from students at multiple institutions. From our analyses, we identified two related progress variables that describe key elements of students' performances: the first describes how students identify and use matter flows in biology phenomena; the second characterizes how students use net rate-of-change to predict how matter accumulates in, or disperses from, a compartment. We also present a case study of how we used our emerging mass balance learning progression to inform instructional practices to support students' mass balance reasoning. Our progress variables describe one way students engage in three dimensional learning by showing how student performances associated with the practice of mathematical thinking reveal their understanding of the core concept of matter flows as governed by the crosscutting concept of matter conservation. Though our work is situated in physiology, it extends previous work in climate change education and is applicable to other scientific fields, such as physics, engineering, and geochemistry.     

人民币汇率变动对我国进出口贸易收支的影响

首先回顾了学术界关于汇率变动对贸易收支影响的研究成果。在此基础上,分析了汇率变动对进出口贸易收支影响的机制。根据不完全替代理论推导出人民币汇率变动影响我国贸易收支的实证模型,并选取1994—2010年度数据,采用ADF检验、Johansen协整检验和Granger因果检验方法对人民币汇率变动对我国贸易收支的影响作了实证分析。实证结果表明,人民币汇率变动对我国贸易收支的影响不显著。文章的最后,提出了相应的对策建议：我国应进一步扩大内需,缓解贸易顺差;控制贸易收支增长的速度以减轻人民币升值压力;中国人民银行应保持人民币汇率水平的相对稳定。     

对运动中机体免疫平衡评价方法的思考

在运动科学领域中,研究者通过测定分别产生IFN-y(或IL-2)与IL-4的外周血、脾脏细胞计数(或百分比),脾脏与外周血细胞在培养与刺激条件下分泌Th1、Th2类细胞因子的水平,以及血液中相关细胞因子含量的方法,从细胞数量与功能上来评价运动中机体的免疫平衡状态。分析认为：(1)Th1、Th2细胞在运动中的变化趋势分别与Tc1、Tc2细胞保持一致,Th1/Th2平衡能间接反映T1/T2平衡的变化。(2)相比细胞数量,细胞因子可能更能有效评价运动中的Th1/Th2平衡。(3)通过淋巴细胞分泌的相关细胞因子水平来评价运动中Th1/Th2平衡时,刺激物等实验条件可影响实验结果。(4)循环血中IFN-y、IL-4的含量可用于间接评定运动中的Th1/Th2平衡。通过对运动中Th1/Th2平衡评价方法的分析与评述,以期为未来相关研究的设计提供依据,为其成果内容的表述提供参考。     

我国体育产业数字化人才培养困境与思路

数字化人才是体育产业高质量发展的中坚力量。在国家实施科教兴国战略、人才强国战略及建设体育强国的宏观背景下,基于产业经济学基本理论,以供需平衡机制为中心,探究体育产业数字化人才培养模式的构建。研究认为:1)供需失衡:体育产业数字化人才供给量少质低,无法满足市场对人才的需求;2)模式固化:高校人才培养模式传统,缺乏对体育产业数字化人才的针对性培养;3)缺乏保障:体育人才流动配置不足;4)机制缺陷:人才评价机制存在缺陷,限制了对优秀人才发掘。结论:建立体育产业数字化人才培养体系,从政府、市场、企业、学校四个维度联合参与人才培养:1)加强政府对人才的保障;2)贯通市场人才流动配置;3)融入企业人才培养管理;4)创新专业人才教育模式。
