A dynamic decision model for portfolio investment and assets management     

QIAN Edward Y.  FENG Ying  HIGGISION James 《浙江大学学报(A卷英文版)》2005,6(Z1)

This paper addresses a dynamic portfolio investment problem. It discusses how we can dynamically choose candidate assets, achieve the possible maximum revenue and reduce the risk to the minimum level. The paper generalizes Markowitz's portfolio selection theory and Sharpe's rule for investment decision. An analytical solution is presented to show how an institutional or individual investor can combine Markowitz's portfolio selection theory, generalized Sharpe's rule and Value-at-Risk(VaR) to find candidate assets and optimal level of position sizes for investment (dis-investment). The result shows that the generalized Markowitz's portfolio selection theory and generalized Sharpe's rule improve decision making for investment.  相似文献

Y.?S.?SiddeGowdaEmail author 《International journal for the advancement of counseling》2004,26(4):421-432

This investigation presents a framework for understanding and also to test the efficacy of Social Work intervention on the well being of the white collared employee (industrial employee) and his/her family. A comprehensive and intensive personal- family exploration was done to uncover the relatedness of seemingly disparate areas of the clients lives. A total of 80 executives (industrial employees) served as subjects. A baseline assessment was done using structured, standardized interview-schedules/questionnaires. The results of the study can be enumerated as follows: After the Social Work intervention, the executives in occupational profile, there were significant changes in Role perception, overload, role conflict, low status and poor peer relations. In coping strategies there was significant improvement in sub-scales like problem solving and unproductive coping. Significant reduction was noticed in their proneness to heart disease, depression, inadequate mental mastery, and perceived ill health. There was significant improvement in their family group support, and in their expressiveness, achievement, orientation, active-recreational and organizational characteristics.  相似文献

幕末、明治时代日本侵华思想检证     

渠长根 《许昌学院学报》2003,22(1):108-112

幕末、明治时代,日本已经开始侵略中国,各种各样的侵华思想不断问世,成为其侵略行动的战略指导和精神支柱。这时的侵华思想以大陆政策为核心和主线,以“神国”理念和民族优越论为特征,是封建扩张主义、殖民主义和民族狂妄主义的混合物,对后来日本大规模的侵华思想理论的泛滥和行动的推进产生了深远的影响。  相似文献

Consensus among stakeholders about success factors and indicators for quality of online and blended learning in adult education: a Delphi study     

Yves Blieck  Ilse Ooghe  Chang Zhu  Koen Depryck  Katrien Struyven  Bram Pynoo 《Studies in Continuing Education》2019,41(1):36-60

Quality models for online and blended learning (OBL) have mainly been developed in higher education. The literature indicates that these models are often conceptualised from the providers’ perspective. What is important for the quality of OBL from the students’ perspective has recently received increased attention in the literature. Consensus among stakeholders about students’ quality needs is useful to support dialogue between professionals to strategically adopt OBL and to ensure that the needs of students are met. This study aims to validate a quality instrument for OBL, taking a set of 74 quality indicators and analysing them in terms of seven success factors (credibility, accessibility, transparency, flexibility, interactivity, personalisation, productivity). The Delphi method was selected as most suited. Participants from adult education were asked to indicate on a 7-point Likert scale to what extent the indicators add to OBL quality to meet students’ needs. After four Delphi rounds, the participants agreed on definitions of success factors and 30 indicators. The results are useful for institutions, ministries of education and external quality assessment agencies to assess the quality of OBL and can support institutions to implement improvement actions to ensure that the needs of students are met.  相似文献   

Assessment,Grade Level and Learning     

Agnes Chang Shook Cheong 《Asia Pacific Journal of Education》1992,12(2):35-47

Researchers have identified assessment as a very crucial influence on the learning strategies adopted by students. The present study carried out on Secondary 2, Secondary 4, and Junior College 2/Pre-University 3 students shows that the Singapore students did not favour the Surface Approach in their learning of English and Mathematics. The nature of the discipline and the cognitive demands of the examinations carried considerable importance for students in their choice of learning strategies. Despite the heavy emphasis on excelling in examinations, students did not rely solely on surface and achieving strategies to attain their goals.  相似文献
