医学成人"专升本"教学模式的初步探讨

成人教育中的专升本学生和普通高等教育学生相比具有明显不同的特点,针对这些特点,目前在教学理念、教学模式上出现了一些问题,本文对此进行了积极的探讨,并提出相关的改善措施。     

中国古代对黄河源头的多元思考

黄河流域是中华民族的摇篮,对于中国的文明进程有着极为重大的影响,由此,也激发了人们对黄河源头的兴趣。黄河的源头究竟在哪里,对于中国人而言,     

知识审计理论及其案例研究——以××建筑科学研究院为例

知识审计是知识管理领域的又一个新的课题,即是在组织中建立一个实质且有效的知识及知识管理评估考核的机制,以便能帮助组织了解自身知识状况并控制及定期审视、评估知识管理的执行情况,以提升组织实施知识管理的成效.在此前提下再完成知识的保存、检索、利用、分享、创新等活动,进而为企业带来更大的价值.文章首先系统介绍了知识审计的含义、研究对象、研究流程以及研究方法等相关的基础理论知识,尤其针对知识审计的方法重点进行比较和分析,并提出改进的建议,并选取了某建筑科学研究院作为对象进行实证研究,验证了所提出的知识审计方法的可行性.     

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.     

冬日里的一脉艺术温情——残疾女画家汪玉婷的故事感动衢州

隆冬的一天,龙游县丹青女社的一群女画家专程来到开化县,与身患绝症、但在工笔画领域耕耘了20多年的残疾女画家汪玉婷进行了一次特殊的互动交流。汪玉婷始终以一支画笔抗击病魔,并把自己精心创作的艺术品拍卖,全部所得捐给了贫困大学生。
