Learning through working: a case study of Chinese college students in South Korea

This qualitative case study was designed to provide an understanding of the work experience of Chinese college students in South Korea. A growing number of Chinese students are coming to South Korea for college education, and their aspirations for better work materialize into work experiences in South Korean businesses. In-depth interviews were conducted with five Chinese students to investigate their learning experience at local workplaces. The Chinese students' work experience not only led them to a deeper understanding of local culture and language, but also gave them integral learning within an experiential, situated learning environment.     

《觉醒》——一部生态女性主义的杰作

凯特·肖邦的《觉醒》一直被认为是女性主义意识觉醒的一部代表作,本文试图从生态女性主义的角度对这部小说进行解读,从女性与自然的亲近性入手分析女主人公艾德娜女性主体意识觉醒的内因与外因。此外,小说中的多重意象也充分反映了作者的生态女性主义意识。     

新文科建设中的教师学术领导力探析

跨学科合作是推动新文科建设、促进文科教育创新发展的基本路径,但在面对文科教师"单枪匹马"的传统科研方式、学科交叉融合发展"老大难"问题以及学术虚假合作等学术合作困境时就需要发挥教师学术领导力的关键作用.在新文科建设实践中,骨干教师和领军人物通过价值观引领、目标定位、持续推动、成果提炼四个具有特定运行逻辑的作用环节,对团队成员围绕共同学术目标进行的实质性合作产生影响力,而这些作用环节综合影响力的大小取决于其前后连贯、自成闭环的运行逻辑.

Improved approaches to stability criteria for neural networks with time-varying delays

In this paper, the problem of stability analysis for neural networks with time-varying delays is considered. By the use of a newly augmented Lyapunov functional and some novel techniques, sufficient conditions to guarantee the asymptotic stability of the concerned networks are established in terms of linear matrix inequalities (LMIs). Three numerical examples are given to show the improved stability region of the proposed works.

从同行通讯评审意见看不予资助项目申请书中的共性问题

国家自然科学基金(以下简称"科学基金")是我国支持基础研究的主渠道之一.多年来,在促进我国基础研究工作开展,提高基础研究水平,增强原始创新能力等方面发挥了重要作用,日益受到科学界的重视[1].由于科学基金资助项目申请数量逐年增长,而资助率维持相对稳定的水平,因此竞争日趋激烈[2].作为科学基金资助项目的申请书,其质量高低成为项目能否获得资助的关键因素之一[3].目前,科学基金资助项目的评审主要采用同行评议的方法.     

Synchronization of discrete-time complex dynamical networks with interval time-varying delays via non-fragile controller with randomly occurring perturbation

This paper addresses synchronization problem for discrete-time complex dynamical networks with interval time-varying delays. In order to achieve the synchronization, a feedback controller subjected to randomly occurring perturbations will be considered. The randomly occurring perturbations are assumed to belong to the Binomial sequence. By constructing a suitable Lyapunov–Krasovskii functional, and utilizing reciprocally convex approach and Finsler?s lemma, the synchronization criteria for the networks are established in terms of linear matrix inequalities (LMIs) which can be easily solved by various effective optimization algorithms. The networks are represented by the use of Kronecker product technique. The effectiveness of the proposed methods will be verified via numerical examples.
