通过对呼吸内科住院医师培训人员进行问卷调查的方式,了解呼吸内科临床教学中存在的缺陷和不足,对教学过程中存在的问题深入探讨,发现"启发性挫败"教学法和问题教学法穿插到传统教学模式中,能更好地提高临床教学效果和质量。  相似文献   

日俄战争后清政府在满洲的外交政策及其失败     

张同侠 《宜宾学院学报》2006,6(5):63-64

日俄战争后,日俄分别加强对南、北满洲的渗透。清政府为了应对危急局势,采取了在满洲引进欧美资本以牵制日俄的政策。但一方面由于清政府实力太弱,无力与日俄周旋,另一方面又由于当时英法俄日四国在远东已形成了合作局面,而美国为了维护其在菲律宾的利益,不愿公开与诸强对立,从而使清政府的政策遭到了失败。  相似文献

Causes of Educational Failure among Elementary School Students in Brunei Darussalam as Perceived by Mathematics and Science Teachers     

Bob Chui-Seng Yong 《Asia Pacific Journal of Education》1997,17(2):31-39

This study investigated causes of school failure among elementary school students in Brunei Darussalam. Fifty-two specialist mathematics and science teachers were involved in the investigation using a questionnaire. The student factor identified to be the most important was related to students' poor command of the English language. Lack of interest in learning was another important influencing factor in students' failure. Parental factors perceived to be the most important were lack of supervision of their children's activities at home and reluctance to make school visits to see teachers about their children's academic progress. The influence of teacher factors on educational failure was perceived to be less important.  相似文献   

基于自动变速器的油质分析及故障判断     

石爱勤  靳生盛 《青海师专学报》2008,28(5)

汽车自动变速器故障中因自动变速器油的问题引发的故障大约占到80％左右,其中,部分是由于自动变速器液面高度不正常而引起的,部分是由于自动变速器油变质或使用的自动变速器油不是既定牌号引起的,本文通过对油质状态进行认真仔细的研究分析,给出自动变速器油变质的原因,并进一步分析了油液变质后所能引起的故障。  相似文献

智能语音故障报警系统的研制     

郑利敏  高保真 《科技广场》2007,(3):202-203

在故障报警处理方面,传统方式一般采用指示灯、文字显示或故障代码存储方式,如能在原有方式基础上给予语音提示,报警方式将更为直观方便,产品也会给人耳目一新的感觉。本文以89C51单片机和ISD语音芯片为核心,设计了一种智能语音故障报警系统,较适合于某些场合故障报警处理的需求。  相似文献   

Persisting students’ explanations of and emotional responses to academic failure

ABSTRACT

Academic failure is an important and personal event in the lives of university students, and the ways they make sense of experiences of failure matters for their persistence and future success. Academic failure contributes to attrition, yet the extent of this contribution and precipitating factors of failure are not well understood. To illuminate this world-wide problem, we analysed institutional data at a large, comprehensive Australian university and surveyed 186 undergraduate students who had failed at least one unit of study in 2016, but were still enrolled in 2017. Academic failure increased the likelihood of course attrition by 4.2 times. The students who failed and persisted attributed academic failure to a confluence of dispositional, situational, and institutional factors. There was a compounded effect of academic failure on already-vulnerable students resulting in strong negative emotions. Viewing persistence as an interaction between individuals and their sociocultural milieu opens up different avenues for research and considerations for support.  相似文献   

岩体地震破坏机理及地球物理特性变异探讨     

丁梧秀  王鸿毅 《洛阳工业高等专科学校学报》2009,19(1)

对强地震多发区黄河黑山峡下游段岩体破坏特征进行了分析,研究表明,地震作用下裂隙的生成与地震波的传播具有同时性、继承性和纵横渡在岩体破坏中的拉张和剪切共同作用的双重性等特点.对岩体地震破坏机理及岩体地震破坏模型进行了初步探讨.同时对地震破坏后岩体地球物理特性的变化进行了研究,发现研究区大范围地球物理参数明显变异,说明强震对坚硬的岩体同样具有严重的破坏性.  相似文献   

Information Systems and Developing Countries: Failure, Success, and Local Improvisations   总被引：5，自引：0，他引：5  

Richard Heeks 《The Information Society》2002,18(2):101-112

This article presents evidence that--alongside the successes-- many information systems in developing countries can be categorized as failing either totally or partially. It then develops a new model that seeks to explain the high rates of failure. The model draws on contingency theory in order to advance the notion of design-actuality gaps: the match or mismatch between IS designs and local user actuality. This helps identify two high-risk archetypes that affect IS in developing countries: country context gaps and hard-soft gaps. The model is also of value in explaining the constraints that exist to local IS improvisations in developing countries. Overall, the article shows how model and theory help understand IS cases in developing countries, and equally, how those cases provide valuable data to help develop IS models and theories.  相似文献
