Performance of Fourth-Grade Students with Learning Disabilities on Multiplication Facts Comparing Teacher-Mediated and Technology-Mediated Interventions: A Preliminary Investigation

Instructional applications (apps) are educational software programs that can be accessed via mobile technologies (e.g., iPad, smartphone) and used to help students acquire various academic skills, including mathematics. Although research suggests that app-based instruction (AI) can be effective, there is a paucity of research comparing AI, to teacher-directed instruction (TDI) or to a combination of instructional approaches (CI) involving both AI and TDI in tandem. In an alternating treatments design, we compared AI, TDI, and CI conditions during instruction targeting multiplication facts with six students with learning disabilities. Results were inconsistent across students, and no condition emerged as consistently better than the others. Students completed social validity rating scales, and all approaches were favored by at least one student. Our results support findings from previous research involving similar comparisons between these instructional formats in which no (or minimal) differences across conditions were detected. We conclude that there may not be a meaningful difference between the outcomes achieved using AI, TDI, or CI for many students. Results are discussed in terms of directions for the future research.     

Exploring the Ethical Aspects of Leadership: From a Korean Perspective

Theories of ethical leadership provide important insights about the effect of leader’s ethics on the relationship between leaders and followers. However, there is an increasing demand for addressing key constructs that enhance the capacity to explain theoretical aspects of ethical leadership. The purpose of this study is to expand the theoretical framework of ethical leadership based on Korean traditional leadership by focusing on personal cultivation, morality, and social responsibility. Using a framework of intrapersonal process as leadership and core value and competence as components of leadership, this study examines the ethical aspects of Korean traditional leadership and provides the implications to further develop the theory of ethical leadership. It is found that ethical integrity ensued from sugi (self-cultivation) is an essential precondition to develop leadership, and the core value of ethical leadership includes Zhixin-Chijing (cultivation of the mind and internal piety) and the competence consists of both Ipzhi (setting a solid self-vision/establishing goal) and Silsim (practical mind, grasp changes in reality with a sound mind) in Korean traditional leadership that contributes to expanding the theoretical understanding of ethical leadership. Implications for future research in the area of ethical leadership are discussed.     

针灸治疗周围性面瘫随机对照研究的文献分析

遵循循证医学评价文献的原则,在中国生物医学文献数据库、CNKI等数据库全面检索2002—2006年间的相关文献并进行计量学评价分析。共检索出文献1284篇,其中RCT文献共有169篇,按照循证医学评价文献的原则及方法,从研究对象、随机分配方法、对照措施、盲法采用情况等多个方面进行分析评价。2002—2006五年间报道的RCT数量比从建国到2000年报道的RCT数量多,但仍需进一步改善文献质量。     

"管办分离"模式下公立医院出资人制度的探索——以上海申康医院发展中心为例

上海申康医院发展中心是卫生领域推进政事分开、管办分开的一次改革试点,以上海申康医院发展中心为例,分析该模式探索公立医院管理体制改革,建立所有权与经营权适度分离,管资产与管人、管事相结合的市级医院出资人制度,促进市级医院加强内部管理,构建有效的约束激励机制,不断提高医院的营运质量和绩效的成功经验。     

树鼩的社会挫败抑郁模型

创制理想的动物模型是突破抑郁症研究的技术难点之一。来自进化研究的证据提示, 树鼩属灵长类近缘的一种小型动物, 具有较为发达的神经系统和与人类相似的应激系统, 因而可能成为创制精神疾病行为模型的较佳选择。已有的研究表明, 树鼩社会挫败模型可能具有比啮齿类更好的表面效度、预测效度及结构效度。由于树鼩与人类的近缘关系, 对其抑郁行为的脑机制研究或药物评价可能更具潜在价值。但是, 该模型仍有待进一步利用、拓展和完善。     

心境对未来事件发生概率判断的影响

本研究采用短影片人为诱发心境的方法,用正性和负性两种情绪事件作为刺激材料,在控制人格变量的前提下,探讨了大学生在不同心境下对未来事件发生概率的判断中是否存在心境一致性效应。结果表明：（1）愉悦心境会增加做出积极判断的倾向,悲伤心境会增加做出消极判断的倾向;（2）无论是在愉悦心境还是在悲伤心境中,被试在对未来事件发生概率的判断上不存在性别差异。结果支持心境对未来事件发生概率判断有所影响,即诱发的心境与未来事件的效价存在一致性效应。     

骨科新进展与教学补充内容的选择

骨科新技术新理论发展迅速,而教科书的内容相对滞后,在教学中为兼顾新知识和教科书内容,采取适当补充短小精练内容的方法,对四肢骨折、脊柱、肿瘤等内容进行补充讲解,并在某些地方加入一些现代医学伦理方面的知识,使学生能更全面地了解骨科,而不增加学生的负担.
