How Do Transfers Survive after “Transfer Shock”? A Longitudinal Study of Transfer Student Departure at a Four-Year Institution     

Terry T. Ishitani 《Research in higher education》2008,49(5):403-419

Prompted by the notion of “Transfer Shock”, numerous studies examined academic performance of transfer students at senior institutions. However, few studies are found that examine how the varying nature of semester GPAs impact subsequent persistence behavior of transfer students after the initial drop in their college GPAs. Using an institutional data set, this study longitudinally investigated departure behavior of transfer students at a senior institution. Particular attention was given to how entry at different times and semester GPAs affected transfer student departure. Results indicate that during their first semester, sophomore and junior transfer students were 73% less likely to depart than freshman transfer students. After controlling for explanatory variables, higher semester GPAs were positively associated with higher persistence rates throughout the observation period.

影响中国基金短期业绩的市场因子分析   总被引：4，自引：0，他引：4  

周志中  郭燕  周志成 《预测》2002,21(2):29-33

通常认为基金业绩受市场风险因子影响 ,因而在评价基金业绩时也使用市场风险因子分析法 ,其中较为流行的是Jensen指数法 ,但本文使用Jensen指数法对 1999年 6月至 2 0 0 0年 12月的投资基金进行回归后发现Jensen指数法回归结果并不显著。本文转而使用另一种市场因子分析法———Fama&French的“三因子模型”来进行基金业绩评估 ,结果发现这个模型对我国基金收益率的解释能力也很低 ,说明影响中国基金业绩的市场风险因子不是 β值、HML、SML。本文对两个模型在我国基金评估上的失败提出了解释 ,并利用Hendricks、Dar ryll、Patel、Zeckhauser、Russ的研究结果对回归方程的结构进行了修正 ,使其对基金收益率的解释能力大大增强。改进之后的方程结构表明 :影响中国基金业绩的市场因子是基金业绩自身的持续性 ,部分优秀基金业绩受自身成长性影响。  相似文献

《飘》中白瑞德人物分析     

令亚贞 《漯河职业技术学院学报》2012,11(4):65-67

《飘》是美国女作家玛格利特·米切尔1936年创作的一部长篇小说。作品以美国内战及战后重建时期为背景,以斯佳丽、白瑞德曲折动人的爱情故事为主线,描绘了一幅壮阔而生动的南方社会的生活画面。文章从三个方面分析男主人公白瑞德的人物形象,展示这一人物形象所赋予作品的永恒魅力：一是白瑞德对旧道德的反叛精神,二是白瑞德对战争前后不同环境的适应能力,三是白瑞德对斯佳丽爱情的执着精神。  相似文献   

高管认知、行业管制与企业创新持续性     

余芬  樊霞 《科研管理》2022,43(12):173-181

创新持续性对于企业构建动态竞争优势具有重要意义,但如何激励企业持续创新仍是学界迫切希望解答的关键问题。基于高阶理论和认知视角,创新性地将高管认知拓展为高管认知水平和高管认知独特性,并分别通过文本分析法和文本向量法进行捕捉,从理论和实证上研究了高管认知的不同特征如何影响企业创新持续性。利用中国制造业上市公司面板数据进行检验,研究结果表明：高管对技术创新的认知度越高,越可能提升企业创新持续性;高管对技术创新的认知视角越独特,企业创新持续性显著更强,且二者具有互为增强的效果。同时,考察典型的中国特色因素—行业管制所发挥的调节作用,结果表明,行业管制水平较高时,高管认知水平和高管认知独特性对企业创新持续性的促进效果显著更弱。研究结论进一步拓展了高阶理论以及高管创新认知的特征维度,深化了不同特征的认知如何影响企业创新的研究内容,并对认识中国情境下制造业企业的创新持续性问题有现实启示。  相似文献   

国际蒙台梭利教育协会(AMI)的历程、特点与趋势     

洪明  李安琪 《教育文化论坛》2020,12(3):24-32

AMI是由蒙台梭利本人亲自创建的蒙台梭利组织,经过91年的发展,已经成为国际上蒙台梭利教育界最富权威的机构,在蒙台梭利教育运动中发挥着引领和标杆性的作用。AMI有自己的课堂教学标准和认可层级制度,在教育实践中产生了良好的教学效果,形成了自己的教育特色。在长期教育实践中,AMI以恪守蒙台梭利教育思想原意而著称,被视为蒙台梭利教育中的守成派或旧派。但近些年该组织的发展规划和行动表明,发展与创新成为该组织的主旋律。AMI将在坚守与创新中继续发挥它在蒙台梭利教育界不可或缺的重要作用。  相似文献   

Sense of Belonging as a Predictor of Intentions to Persist Among African American and White First-Year College Students   总被引：1，自引：0，他引：1  

Leslie R. M. Hausmann  Janet Ward Schofield  Rochelle L. Woods 《Research in higher education》2007,48(7):803-839

This study investigates the role of students’ sense of belonging to their university in college student retention. Using individual growth curve modeling, we examined (a) whether sense of belonging predicts intentions to persist, and (b) the effects of an intervention designed to enhance students’ sense of belonging. African American and white first-year students completed surveys three times throughout the academic year. Students were randomly assigned to a group that received an intervention to enhance students’ sense of belonging or to one of two control groups. Sense of belonging was found to predict intentions to persist, controlling for background variables and other predictors of persistence. Overall, sense of belonging and intentions to persist declined over the academic year. However, the decline in sense of belonging was smaller for students in the intervention group. Implications for the development of college retention programs and for existing models of student persistence are discussed.  相似文献   

Parental Involvement in Math Homework: Links to Children’s Performance and Motivation     

Gintautas Silinskas  Eve Kikas 《Scandinavian Journal of Educational Research》2019,63(1):17-37

The present study examined the longitudinal associations between children’s perceptions of parental involvement in math homework (control and support) and their math performance and motivation (task-persistent homework behavior and math self-concept). Children (n = 512) reported their perceptions concerning parental involvement in sixth-grade math homework. In grades 3 and 6, children completed math tests, evaluated own math self-concept, and their mothers (n = 420) evaluated task persistence during homework. The results showed that low self-concept in math predicted increased parental control, which in turn related to low math performance, task persistence, and math self-concept. Second, perceived parental support was related to increased task persistence during homework. Finally, parental control was especially detrimental for boys’ task persistence and math self-concept.  相似文献
