Shear capacity of reinforced concrete columns strengthened with CFRP sheet

INTRODUCTION There is increased need in recent years for strengthening or rehabilitation of existing reinforced concrete structures adversely affected by overloading, construction material deterioration, seismic loads, structural deformation, etc. An effective method for increasing the shear capacity of reinforced concrete columns is the use of externally bonded carbon fiber reinforced plastic (CFRP) systems (ACI, 2002). FRP systems were first applied to reinforced concrete col-umns i…

A Diagnostic-Remediation Teaching System for Enhancing Elementary Students’ Science Listening Comprehension

The purpose of this study was to explore elementary students’ listening comprehension changes using a Web-based teaching system that can diagnose and remediate students’ science listening comprehension problems during scientific inquiry. The 3-component system consisted of a 9-item science listening comprehension test, a 37-item diagnostic test, and 107 scaffoldings of listening strategies. The diagnostic and remediation system was trialed with grade 6 students (N?= 526) from southern Taiwan who were selected by cluster sampling. The participants were asked to take the 3 components individually on a computer. The students’ responses were collected and analyzed to document performance and changes. Results indicated that the diagnostic test had a positive influence on science listening comprehension proficiency and addressed potential problems, while the scaffolding helped remediate confirmed listening difficulties. Instructional implications for classroom diagnosis–remediation applications are discussed and future research is outlined.     

What if best practice is too expensive? Feedback on oral presentations and efficient use of resources

We evaluate feedback methods for oral presentations used in training non-quantitative research skills (literature review and various associated tasks). Training is provided through a credit-bearing module taught to MSc students of banking, economics and finance in the UK. Monitoring oral presentations and providing ‘best practice’ feedback is very resource-intensive. Do we withdraw oral presentations from the module, because best feedback practice is prohibitively expensive in a world of limited resources, or choose a second-best alternative? To what extent might the latter compromise intended learning outcomes? We used the same provision of video feedback for all students but used two verbal feedback regimes. For one regime, we decreased the amount of verbal feedback and increased the number of presentations. The impact was measured by academic outcome, rating scales and questionnaire. Overall satisfaction with the module was very high for both feedback regimes, and there were no statistically significant differences between regimes, suggesting that less resource-intensive methods need not compromise learning outcomes.     

Online Proctored Versus Unproctored Low-Stakes Internet Test Administration: Is There Differential Test-Taking Behavior and Performance?

Online higher education institutions are presented with the concern of how to obtain valid results when administering student learning outcomes (SLO) assessments remotely. Traditionally, there has been a great reliance on unproctored Internet test administration (UIT) due to increased flexibility and reduced costs; however, a number of validity concerns have led some researchers to question its implementation and results. To mitigate the limitations of UIT, a relatively new approach, referred to as online proctoring, has been developed to mirror in-person proctoring remotely by capitalizing on technology to create verifiable and secure testing conditions. This study evaluated the comparability of online proctored and unproctored test administration in a low-stakes testing context on user-friendliness, examinee behavior, and mean scores. Results demonstrated improved user-friendliness (e.g., ease of logging in); however, no significant differences were observed in terms of keystroke information, rapid guessing, or aggregated scores between proctoring conditions. Overall, these results suggest that online institutions can implement UIT, which is a cost-effective approach to test administration, and obtain valid group-level inferences from SLO assessments.     

纯电动汽车动力系统参数匹配与优化研究

基于某款纯电动汽车整车性能要求进行了关键部件的参数匹配,通过搭建CRUISE模型在NEDC工况下的仿真验证了参数匹配的合理性。基于ISIGHT和CRUISE联合仿真,以续驶里程为优化目标,以主减速比和动力电池的并联电池组数为优化变量,采用NSGA-II算法进行了优化分析,优化结果显示,此款纯电动汽车续驶里程得到了有效提升,且动力性也满足预定要求。     

对教育教学行为的理性反思

法国诗人保罗·佛特有一首非常优美的诗:世上 所有的男孩／世上所有的女孩/如果给他们机会让他 们统治世界他们就会把这世界变成巨大无比的 ……／一个环形。但要想使这个环形精美绝伦,需要 精心的打磨,也就是说需要科学有效的教育辅助完 成。从事教育的工作者,完全有必要时常对自己的教     

浅论《纳扎尔爱情诗集》中的爱情悲剧

维吾尔族诗人阿不都热依木.纳扎尔的《纳扎尔爱情诗集》自觉地按照悲剧的审美规律为世人谱写了一组凄美动人的爱情乐章。《诗集》中爱得热烈、爱得痴迷的恋人们在遭受种种阻挠后,只能以牺牲自己的生命来捍卫爱情。《诗集》表达了对封建制度和封建礼教的强烈控诉,从爱情的被毁灭中激起人们对爱情的珍惜、热爱和追求,以巨大的愤怒去憎恶和仇恨扼杀爱情的丑恶势力,从而为埋葬丑恶事物而斗争。
