高校共青团团员意识教育长效机制建立研究

高校团员数量占学生总数的95%以上,团工作的优劣,团员表现的好坏直接影响着学校的整体工作.当前在全团开展增强团员意识主题教育活动,是共青团加强自身建设的一项重大战略举措.构建团员意识教育的长效机制,有利于长期深入广泛地开展团员意识教育工作,要从思想教育、组织建设、团务管理和"党建带团建"等方面去考虑.     

绿色贸易壁垒对广西农产品出口的影响及其法律对策

随着关税等传统壁垒在国际贸易中作用的减弱,绿色贸易壁垒逐渐成为国际贸易中的主要保护措施。广西是一个经济欠发达地区,其农产品出口近年来遭受了绿色贸易壁垒的打击。广西应采取完善国际性的环境保护公约内容,完善国内的环境保护立法,积极推行ISO 14000国际系列标准,完善外商投资规则,加速绿色食品的生产,积极起诉明显带有歧视性的绿色贸易壁垒等法律对策。     

中美政府对高校科技创新的支撑作用比较分析

美国政府对高校科技创新活动的支持始于第二次世界大战期间.二战改变了美国的科研模式,确立了政府与高校在科研领域的新型合作关系.而中国高校科技工作受到政府的重视并得到快速发展则是在20世纪80年代以后.虽然中美两国政府都主要从政策和资金两个方面为高校科技创新活动提供支持与引导,但在支持的强度、支持的目的和引导的方向上存在较大差异.只有深入比较这些差异及分析产生差异的原因,才能为中国政府加强对高校科技创新的支撑作用提供可靠的理论和实践依据.     

应用现代教育技术提高教育教学质量

非营利组织视野下的高校教师管理

高校教师管理工作的关键在于如何帮助教师正视自身所承载的教育使命,处理好教育与科研、生存与发展、个体与组织等一系列关系。本文从高校的非营利组织特性入手,紧扣教师作为非营利组织成员应充分强调其职业理想与价值实现的这一特点,指出在高校教师管理中,尊重与保护教师的理想信念,构建积极有效的“对话”关系,分阶段地展开职业生涯规划,实现教师个体发展与高校发展的和谐统一。

Hard thresholding regression

In this paper, we propose the hard thresholding regression (HTR) for estimating high‐dimensional sparse linear regression models. HTR uses a two‐stage convex algorithm to approximate the ?₀‐penalized regression: The first stage calculates a coarse initial estimator, and the second stage identifies the oracle estimator by borrowing information from the first one. Theoretically, the HTR estimator achieves the strong oracle property over a wide range of regularization parameters. Numerical examples and a real data example lend further support to our proposed methodology.     

Functional and emotional traits of corporate social media message strategies: Behavioral insights from S&P 500 Facebook data

Drawing from literature regarding public engagement, the Elaboration Likelihood Model (ELM), computer-mediated communication research, and emotion psychology, this study examines the effects of companies’ social media communication strategies on public engagement behaviors as indexed by post likes, shares, and comments. Specifically, it investigates how corporate Facebook posts’ functional traits (functional interactivity and vividness) and emotional traits (emotion presence, valence, and strength) impact public engagement online. Through data mining and computer-assisted sentiment analysis of 33,379 posts from 106 Standard & Poor 500 companies’ Facebook accounts, this study finds a negative effect of functional interactivity but a positive effect of vividness on engagement. It also shows that emotional traits overall yield stronger public engagement outcomes. Two-way interactions between emotional and functional features are also detected. Theoretical and practical implications are discussed.     

Finding the vulnerable among China’s elderly: identifying measures for effective policy targeting

Facing a rapidly aging population, China has recently started to formulate and implement policies with the aim to provide old-age care. While well-developed old-age care policies commonly include a built-in component that assesses eligibility based on vulnerability, no such process is established in the context of China. Here, based on data from the China Health and Retirement Longitudinal Study collected in both 2011 and 2013, we (a) developed a simple and effective strategy for identifying vulnerable Chinese elderly, which can serve as a basis for policy targeting, and (b) improved the policy relevance and targeting efficiency of this vulnerability measure by including additional health indicators. Our vulnerability measures identify 35% to 46% of Chinese elderly as vulnerable, covering up to 67% of elderly at high risk of death or functional decline. They can serve as an initial screening step for more comprehensive geriatric assessments and enable policy makers to effectively target vulnerable elderly persons in China.     

两种理论视野下的西欧穆斯林政治参与问题探析

20世纪60年代以来,穆斯林已经成为西欧社会不容忽视的现实存在,但是在政治参与方面,穆斯林远未能有效参与西欧各国的政治进程。穆斯林人口在种族、经济地位等方面的多样性是其有效参与政治的内在障碍。从资源动员理论和政治机会结构理论的分析可以发现,穆斯林对公民权、政治精英、参政渠道等政治资源的占有不足,加之欧洲殖民心理遗产的影响、欧洲的世俗化政策、伊斯兰恐惧症、外部穆斯林世界的影响等多种因素,共同构成了影响穆斯林广泛参与西欧政治生活的重要原因。
