本文首先分析了1985－1990年间我国能源地区供需平衡格局出现的三个新变化以及主要四片缺能区的空间分布。接着，采用经过修订的能源消费因素分析法（RRS分析法），指出工业总量增长和能源利用效率是决定我国主要缺能区消费增长的两项主导因素，工业结构性节能的作用十分微弱，能源供求、缺能区、因素分析法  相似文献   

Mixed control of uncertain jumping time-delay systems     

Magdi S. Mahmoud  Fouad M. AL-Sunni  Yan Shi   《Journal of The Franklin Institute》2008,345(5):536-552

In this paper, we investigate a class of linear continuous-time systems with Markovian jump parameters. An integral part of the system dynamics is a delayed state with time-varying and bounded delays. The jumping parameters are modeled as a continuous-time, discrete-state Markov process. Employing norm-bounded parametric uncertainties and utilizing the second-method of Lyapunov, we examine the problem of designing a mixed controller which minimizes a quadratic performance measure while satisfying a prescribed -norm bound on the closed-loop system. It is established that sufficient conditions for the existence of the mixed controller and the associated performance upper bound could be cast in the form of linear matrix inequalities.  相似文献   

支持型组织责任对员工创新行为的影响——有调节的中介效应模型检验     

张毅  黄福华 《软科学》2016,(7):94-98

引入积极情绪、供给需求匹配作为中间变量,建立支持型组织责任影响员工创新行为的有调节的中介效应模型。实证研究结果显示,支持型组织责任对员工创新行为具有积极的正向影响,其效用受到供给需求匹配的调节;人际支持完全通过个体积极情绪来影响员工创新行为,组织支持对员工创新行为的影响部分受到个体积极情绪的中介;积极情绪对员工创新行为的影响受到供给需求匹配的调节,研究结论有效地解释了以往研究的分歧。  相似文献

我国寿险需求影响因素的实证分析   总被引：14，自引：0，他引：14  

杨舸田澎  叶建华 《中国软科学》2005,(3):50-54

应用自回归分布滞后模型对我国寿险需求进行了实证研究。与已有的研究相比，本文消除了保费收入数据中因统计口径变化带来的影响，建模时考虑了时间序列的平稳性，而且考查了更长的时间跨度。研究表明，国内生产总值的增长和寿险业自身的发展是寿险需求增长的根本原因，实际利率和少年儿童赡养(抚养)率对寿险需求也有显著的影响，社会的老龄化、预期通货膨胀率和不断提高的教育水平对寿险需求的作用并不显著。  相似文献

Labour market intermediaries: a corrective to the human capital paradigm (mis)matching skills and jobs?     

Tony Dobbins  Alexandra Plows 《Journal of Education & Work》2017,30(6):571-584

The orthodox supply-side human capital theory (HCT) paradigm is inadequate for understanding and adjusting to labour market volatility in UK regional economies like Wales. This article explores the role of regional labour market intermediaries (LMIs) in matching supply (skills) and demand (job opportunities) in regional labour markets. Some LMIs emerge because the HCT paradigm is failing. One Welsh LMI, Shaping the Future (StF), is explored empirically using qualitative methods. StF mainly adopted HCT tenets, but with some emergent demand-side focus. Despite helping workers adjust to labour market shocks, LMIs are not equipped to fix the structural demand-side problem of finite quality job opportunities in deindustrialized regions that accentuate skill use. A broader ‘skill eco-system’ paradigm is required, emphasising the foundational economy.  相似文献   

Career plans of final-year South African student teachers: migration to ‘greener pastures’?     

J. J. R. de Villiers 《Africa Education Review》2017,14(3-4):212-229

Teacher loss due to migration is a global phenomenon that impacts both developed and developing nations the world over. The aim of this study was to find out about the career plans of final-year South African student teachers. A group of final-year Bachelor of Education student teachers from a South African university responded to a questionnaire on intra- and intercontinental migration. The responses were analysed quantitatively and/or qualitatively. The findings showed that 79% of the students indicated that they would be teaching in South Africa, 8% were planning to teach in another country, while 8% were undecided. More than a third of the students (38%) said that they would like to teach in another country in five years’ time. Just more than a quarter of the students (27%) preferred Australia as a destination country. The student teachers’ most important motive to teach in a foreign country was the opportunity to travel, followed by earning a higher salary, and professional development. The student teachers indicated that their most important migration needs before leaving South Africa were information about health care, accommodation, and banking assistance.  相似文献   

College/University Counseling Centers Supporting Study Away: Challenges and Opportunities     

Charles C. Morse  Janet Dee Spoltore  Paul Galvinhill 《Journal of College Student Psychotherapy》2017,31(4):325-335

Research points to significant numbers of students on college campuses experiencing mental health distress and an ever increasing number of college students who are choosing to make an off-campus educational experience a part of their college careers. When we consider both of these trends together, it is quite apparent that a significant number of students with mental health concerns will spend periods of time studying away from campus, with converging concerns among college mental health and study away professionals about how to best support these students. This article seeks to outline both challenges and opportunities inherent in the collaboration between campus professionals in supporting students with mental health issues before and during their study away experiences.  相似文献
