With the growing demand for places in German universities, the present system of allowing entrance to everyone who holds the Abitur has become unsatisfactory. This paper looks at ways of controlling the size of the higher education system and allocating resources from the viewpoint of economic theory.Three ideal type educational planning models are sketched, one of which - a market model - is argued to have the greatest advantages. It would involve a state credit scheme for students with repayments via a graduate tax; student fees would provide all or most of the universities' funds. It would remove the inequity of the present system which involves a transfer of income from today's (relatively poorer) earners to tomorrow's, and from those with lower earning potential to those with higher. Since students would be in a position to choose the most satisfying and/or cheapest courses of study and would find it easier to change courses if they wished, it would reward cost-saving and student-satisfying innovation. By providing more finely graded levels of qualification within subject areas, it would reduce the extent to which jobs are ordered hierarchically in an irrational and inefficient way; and the universities would respond more flexibly to changes in labour market demands.This is a translation, with minor amendments, of a paper published in Fundamental Problems of Infrastructure Planning for Growing Economies, Proceedings of the Conference of the Society for Social Policy, Innsbruck, 1970, Berlin: Verlag von Duncker und Humblot, 1971. It is reproduced here by arrangement with the publisher. The article was translated into English by David Webster.  相似文献

Due to the increased pressure from test‐based accountability practices, teachers have reported high levels of stress and burnout. High teacher stress has an impact on school outcomes, including links to absenteeism, burnout, school climate, and teacher behavior management. Teacher stress interventions may be an important first step toward reducing these negative outcomes. Although there have been several recent intervention studies in the domain of teacher stress, there has been no systematic review to compare the type and effectiveness of teacher stress interventions. Included within this review are interventions from a variety of modalities such as knowledge‐based, behavioral, cognitive‐behavioral, and mindfulness approaches. Results indicated that the most effective interventions were in the mindfulness, behavioral, and cognitive‐behavioral domains. Interventions which delivered solely informational content were among the least effective.  相似文献

A sample of one hundred and eleven scientific instrument innovations was studied to determine the roles of instrument users and instrument manufacturers in the innovation processes which culminated in the successful commercialization of those instruments. Our key finding was that approximately 80% of the innovations judged by users to offer them a significant increment in functional utility were in fact invented, prototyped and first field-tested by users of the instrument rather than by an instrument manufacturer. The role of the first commercial manufacturer of the innovative instrument in all such cases was restricted, we found, to the performance of product engineering work on the user prototype (work which improved the prototype's reliability, ‘manufacturability’, and convenience of operation, while leaving its principles of operation intact) and to the manufacture and sale of the resulting innovative product. Thus, this research provides the interesting picture of an industry widely regarded as innovative in which the firms comprising the industry are not in themselves necessarily innovative, but rather — in 80% of the innovations sampled — only provide the product engineering and manufacturing function for innovative instrument users.We term the innovation pattern observed in scientific instruments a ‘user dominated’ one and suggest that such a pattern may play a major role in numerous industries.  相似文献

The paper attempts to develop a mathematical model of the national innovation system (NIS) of Taiwan, particularly with regard to its integrated circuit (IC) industry. The method utilised is that of system dynamics (SD). Drawing on both questionnaire/in-depth interviews and computer simulation, the paper aims to increase insights into the dynamic processes of the Taiwanese IC industry system of innovation and understand the interdependence and interaction among capital flows, human resource flows, knowledge and technology flows, and product flows in the NIS. The paper concludes with some simulations of policy alternatives confronting the IC industry and the Taiwanese government.  相似文献

Increasingly, the literature suggests that the sense of coherence (SOC) positively influences well-being in later life. This study reports the assessment of the following psychometric properties: distributional properties, construct, criterion and external-related validities, and reliability of the Orientation to Life Questionnaire (OtLQ) in an cross-national population of older adults. We recruited 1291 community-dwelling older adults aged between 75–102 years (M = 83.9; SD = 6.68). Convenience sampling was used to gather questionnaire data. The construct validity was asserted by confirmatory factor analysis and convergent and discriminant validity. Moreover, criterion and external-related validities, as well as distributional properties and reliability, were also tested. Data gathered with the 29-items OtLQ scale showed overall good psychometric properties in terms of distributional properties, construct, criterion, and external-related validities, as well as reliability. Three factors were validated for the OtLQ scale: (a) comprehensibility; (b) manageability; and (c) meaningfulness. We validated the three-factor OtLQ scale, which produced valid and reliable data for a cross-national sample with older adults. Hence, it is an adequate instrument for assessing sense of coherence among older people in health care practice and program development contexts.  相似文献

A general method for accurately computing the Lyapunov characteristic exponents (LCEs) of continuous dynamical systems has been developed in [10]. In this paper, this method is extended to implementations on systems of arbitrary dimensions. An accurate implementation of the extension of the method to compute LCEs that uses available numerical techniques is presented for systems of arbitrary dimensions. Previously in [10], the original approach had only been implemented for general systems of up to dimension three. Closed form expressions for the exponential of skew symmetric matrices of order 4 and 5 will be presented. These formulas are used to obtain an accurate and efficient implementation of the method for dynamical systems of dimensions 4 and 5. Numerical examples illustrating the accuracy of the implementations are presented.  相似文献
