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.     

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。
