With special reference to the Paul Sabatier University of Toulouse, the authors trace the development of the French universities from the élitist Napoleonic institutions that they still were in the early 1960's to the mass, diversified institutions of today. They stress the importance of the events of 1968 as a major turning point which had a particularly strong impact because they occurred during a period of prosperity. Thus the wide‐scale expansion, democratization, diversification, and massification which occurred led to a positive reaction to the call for increased vocationalization and co‐operation with industry which characterized the lean years that followed. Other stimuli for change and adaptation have been modifications in the legal structure of higher education, the need to increase offerings in continuing education, policies favouring decentralization and regionalization, and the influence of European Union higher education policies. The need to provide high quality higher education in a number of areas to a very large proportion of the age cohort is understood to be a social and economic necessity. The evolution of French higher education since 1968 could offer lessons and examples to the higher education systems of eastern and central Europe in their efforts to cope with transition. The role of universities in the modern world has been greatly enhanced. Important changes have occurred in French higher education over the past twenty‐five years, the resultpartly of the adoption of new laws, of social evolution, of economic needs and challenges, and of individual initiatives undertaken and voluntary policies adopted by universities.  相似文献

In this study, we analyzed the correlations between hip flexion power; sprint performance, lumbar lordosis (LL) and the cross-sectional area (CSA) of the psoas muscle (PM). Ten young adults performed two sprint tests and isokinetic tests to determine hip flexion power. Magnetic resonance imaging was used to determine LL and PM CSA. There were correlations between hip flexion power, sprint performance, and PM CSA, but LL showed no correlation with any parameter The impact of hip flexion power and LL on sprint stride pattern efficiency was considered. Hip flexion might not have a simple role in the passive knee replacement of the stride pattern; instead, it may be an active parameter. Other investigations are needed to determine the influence of pelvic architecture on sprint performance.  相似文献

Hamstring strains are one of most common sports injuries. The purpose of this literature review is to summarize studies on hamstring strain injury rate, mechanism, and risk factors in the last several decades with a focus on the prevention and rehabilitation of this injury. Hamstring injury commonly occurs in sporting events in which high speed sprinting and kicking are frequently performed, such as Australian football, English rugby, American football, and soccer. Basic science studies have demonstrated that a muscle strain injury occurs due to excessive strain in eccentric contraction instead of force, and that elongation speed and duration of activation before eccentric contraction affect the severity of the injury. Hamstring strain injury is likely to occur during the late swing phase and late stance phase of sprint running. Shortened optimum muscle length, lack of muscle flexibility, strength imbalance, insufficient warm-up, fatigue, lower back injury, poor lumbar posture, and increased muscle neural tension have been identified as modifiable risk factors while muscle compositions, age, race, and previous injuries are non-modifiable risk factors. The theoretical basis of some of these risk factors, however, is lacking, and the results of clinical studies on these risk factors are inconsistent. Future studies are needed to establish the cause-and-effect relationships between those proposed risk factors and the injury.  相似文献

Towards strategic practices in basic research   总被引:1,自引:0,他引:1  
Drawing upon the literature of business management, the authors develop an approach to the problems of managing the large research laboratories which have now become more common but which have to exist in the changed climate of the 1980s. The types of managerial problems which arise are classified, the politics of their management analysed and the form in which these problems manifest themselves is discussed. It is concluded that those who have charge of large laboratories must be determined to implement what the authors describe as strategic practice if the laboratories are to function efficiently.  相似文献

A semi-analytical Monte Carlo (SMC) simulation was developed to simulate the propagation of laser-induced fluo- rescence (LIF) in an optically participating spray, which simultaneously exhibits spectrally dependent emission, anisotropic scattering, absorption, and re-emission. The SMC simulation is described and then applied to an experimental configuration of a cloud of polydisperse droplets composed of water and sulforhodamine B dye. In the SMC simulation, the collected LIF flux on the remote receptor element is calculated as the global contribution from the emissive source, single, twice, … and nth collision events in any sequence. The effects on the fluorescence photons propagation of spray parameters like the dye concentration, droplets concentration, and droplets size are examined. Three spectral bands representing different optical properties are chosen to analyze the interference of absorption, scattering and re-emission on the detected LIF flux. The obtained spectral LIF flux distribution on the receptor demonstrates a “red shift” phenomenon.  相似文献

This study focused on foundational aspects of classroom relations. Specifically, relationships between teachers’ immediacy (interpersonal) behaviours, classroom democracy, identification and learning were considered. Previous work suggests that these variables can be used as a foundation to shape classroom climate, culture and learning outcomes and, by extension, assist educational institutions to achieve their civic mission. This study examined classroom democracy and class identification as variables that mediate the relationship between immediacy behaviours and learning using data collected from 529 students in six institutions of higher learning in Rwanda. Structural equation modeling revealed that classroom democracy mediates the relationship between immediacy behaviours and that classroom democracy and class identification covary substantially. The significant relationships in the final structural model suggest that immediate teachers are likely to have a positive influence on perceptions of classroom democracy, class identification and learning. Based on the growing scholarship of instructional dissent, this study highlights the foundational and strategic aspects underlying these relationships within the context of relating in the classroom and beyond.  相似文献

The large number of secondary school graduates entering higher education is transforming the nature of universities, particularly in literature and the humanities, by changing the relative numbers of students enrolled in different academic years. At the same time this influx is accompanied by a significant failure rate in the first academic year, calling into question the efficacy of the university system. A national issue with local repercussions, the struggle against failure in the first year is leading to much heart-searching among the universities, whose staff are trying hard to understand why certain students abandon their studies. The enquiry described in this article reveals the co-existence of two student populations: those who enter university as an active choice and those who do so by default. In the case of the first group, entry to university represents an investment for the future which must be carefully managed. In the second case it is a matter of going into higher education as a faute de mieux solution in an economic context in which work is scarce.  相似文献
