印度大学附属制对我国独立学院的启示

印度大学附属制是极具特色的印度高等教育制度,与我国目前兴起的独立学院在某些方面有相似性。印度附属学院虽然在推进印度高等教育大众化进程中功不可没,但大学附属制度也给大学的声誉带来了损害。我国独立学院刚刚兴起,从印度附属学院中吸取经验与教训,应在规模数量、办学模式、专业设置、培养质量等方面注意政策引导。     

贫困大学生认定标准研究

资助高校贫困生的首要和核心问题是如何确立贫困大学生认定标准问题。本文认为,确立认定指标,关键是可操作性要强,具有低成本高效率的特性,能从多个角度和层次真实反映学生经济状况,并符合我国国情。     

西方绩效评价研究综述

绩效管理是企业人力资源管理的重要环节和核心内容,如何客观、公正、准确地对员工的绩效做出评价,是目前人力资源管理中的一个重要问题。本文对西方绩效评价研究文献进行了综述,对该领域研究的发展脉络进行了梳理,探讨了绩效评价研究的未来发展趋势。     

基层电大教师的专业身份危机

由于电大运作模式的弊端、教师管理的失范、实践理念的偏差和教师专业发展的滞后造成了基层电大教师身份的内部分化和外部泛化的＂身份危机＂。基层电大教师的教学工作和课程开发明显分离,网络教学新的特征和内涵进一步细化了电大教师的角色,教师岗位职能的细化使教师角色同一化,基层电大大量的管理工作进一步泛化了教师的角色,这些都不利于教师的专业发展。基层电大应通过纯化教师角色和控制教师工作量来提高外部认同度,通过建立教师专业发展标准和教学知识评价机制、重视教学理念的先进性、强调教学创新能力来提高内部认同度。     

An analysis of the nature of classroom activities: A comparative study of an immersion English class and a non-immersion English class in the mainland of China

This study was designed to investigate the nature of activities in an immersion English class and a non-immersion English class in the mainland of China, and to find out the differences between these two types of class through data gained from observation and interviews. Spoken discourse analysis was used to analyze the data, where Engeström??s activity complex system was used as the analytical framework to examine the nature of activities in the two types of classes. The results showed that it is the dynamic and situated nature of activity that makes a difference between the activities in these two classes. The interaction among the activity components, the social relations emerging through the process, the use of target language as the main mediational tool, and the subject content revealed in the activities enhance our emic understanding of the nature of activities. Implications can be drawn for English language teaching and for students?? English language learning for the schools in the mainland of China. This study contributes to both immersion education and classroom interaction.     

Wearable skin-like optoelectronic systems with suppression of motion artifacts for cuff-less continuous blood pressure monitor

According to the statistics of the World Health Organization, an estimated 17.9 million people die from cardiovascular diseases each year, representing 31% of all global deaths. Continuous non-invasive arterial pressure (CNAP) is essential for the management of cardiovascular diseases. However, it is difficult to achieve long-term CNAP monitoring with the daily use of current devices due to irritation of the skin as well as the lack of motion artifacts suppression. Here, we report a high-performance skin-like optoelectronic system integrated with ultra-thin flexible circuits to monitor CNAP. We introduce a theoretical model via the virtual work principle for predicting the precise blood pressure and suppressing motion artifacts, and propose optical difference in the frequency domain for stable optical measurements in terms of skin-like devices. We compare the results with the blood pressure acquired by invasive (intra-arterial) blood pressure monitoring for >1500 min in total on 44 subjects in an intensive care unit. The maximum absolute errors of diastolic and systolic blood pressure were ±7/±10 mm Hg, respectively, in immobilized, and ±10/±14 mm Hg, respectively, in walking scenarios. These strategies provide advanced blood pressure monitoring techniques, which would directly address an unmet clinical need or daily use for a highly vulnerable population.     

当代中国网络公共领域的现实境遇与发展思路

我国网络公共领域的生成恰逢时代契机:国家和社会相对分离以及民主化程度的提高是根本前提;庞大网民群体的形成奠定了公众基础;W eb2.0时代网络的开放性、交互性奠定了技术基础。但同时也面临着现实困境:网络世界不平等是现实世界不平等的延伸;国家必须对网络发挥主导作用,市民社会尚不成熟;网民理性不足,司法规约困难;商业化、娱乐化、私人化倾向损害了网络公共领域的基础。有鉴于此,政府应该做到不缺位、不越位;网络商业主体应该提高法律意识和责任意识;网民应该提高参与能力和参与意识。     

办公建筑孔洞设置对工业厂房通风优化模拟研究

基于计算流体力学CFD软件,建立了数值模型,并对工业厂房的风环境进行了模拟,分析了办公建筑不同的孔洞开启方案对工业厂房通风的影响。研究结果表明:倾角为60°的倾斜孔洞和中心高度为12m的孔洞可以使工业厂房通风效果达到最佳状态。在此基础上,优化了孔洞的设置方式,并结合模拟进行了验证,为工业厂房类建筑通风设计提供决策参考。
