Liam Ryan∗ 《Higher Education in Europe》1993,18(3):81-90
Beginning with an overview of various international initiatives which have been taken in recent years with regard to exchanges of information and experiences on quality assessment in higher education, this article reflects on the adoption of quality assessment techniques and accreditation in the higher education systems of eastern and central Europe. The principles of Total Quality Management (TQM), self‐evaluation, the structures of formal accreditation, and methodological issues of quality assurance are discussed, examples being drawn from several countries. The point is made that the countries of central and eastern Europe must individualize the evaluation and accreditation systems which they choose to adopt in ways which are compatible with specific cultural and national factors while at the same time upholding international norms of quality. 相似文献

BBC Radio Leicester in 1976: Kick Starting British Asian Radio 总被引:1,自引:1,他引:0
Liam McCarthy 《Journal of Radio & Audio Media》2018,25(2):269-283
This article examines how, in 1976, BBC Radio Leicester revolutionized broadcasting to Asian communities in England by launching a 5-nights a week Asian program. Aimed at helping to diffuse the toxic racial atmosphere in the city and improve community relations, the program proved to be a huge success and a direct forerunner of the BBC Asian Network. 相似文献

Biological maturation can be defined as the timing and tempo of progress to achieving a mature state. The estimation of age of peak height velocity (PHV) or percentage of final estimated adult stature attainment (%EASA) is typically used to inform the training process in young athletes. In youth soccer, maturity-related changes in anthropometric and physical fitness characteristics are diverse among individuals, particularly around PHV. During this time, players are also at an increased risk of sustaining an overuse or growth-related injury. As a result, the implementation of training interventions can be challenging. The purpose of this review was to (1) highlight and discuss many of the methods that can be used to estimate maturation in the applied setting and (2) discuss the implications of manipulating training load around PHV on physical development and injury risk. We have provided key stakeholders with a practical online tool for estimating player maturation status (Supplementary Maturity Estimation Tools). Whilst estimating maturity using predictive equations is useful in guiding the training process, practitioners should be aware of its limitations. To increase the accuracy and usefulness of data, it is also vital that sports scientists implement reliable testing protocols at predetermined time-points. 相似文献

In Part I properties of the scale coördinate, of the form: B(n + θ) are discussed. n is shown to be associated with the operation of counting scale marks, θ with the operation of estimating between them, and B, with the operational and configurational aspects of that part of apparatus which lies adjunct to the scale system.In Part II three types of measurement codification are discussed: (a) the differential interval; (b) the finite amorphous interval; (c) the scale interval; a relationship among them is postulated.In Part III the finite differences in scale coördinates are defined and simple theorems are used to illustrate these definitions. Simple difference equations in scale coördinates are solved to illustrate macroscopic “selection principles” arising partly out of the methodology of codifying a coincidence in scale coördinates.In Part IV an example of causally related dimensional systems is described by use of the scale coördinate. This example is taken from the perfect gas law and Van der Waals' gas law. 相似文献

The modern understanding of lubrication is based on the equations of the hydrodynamic theory. These equations, as has been seen, describe the performance of a bearing in terms of the actual film viscosity but, of course, this depends on the temperature of the film, which in general is unknown. We have next to consider whether there is any way of calculating or predicting the steady running temperature of a bearing.It is not commonly realized that there is a rational solution for this problem.The solution depends both on the rate of generating heat by friction, and on the rate of heat transfer from the bearing to its surroundings. 相似文献

Alternating a resistance exercise with a plyometric exercise is referred to as "complex training". In this study, we examined the effect of various resistive loads on the biomechanics of performance of a fast stretch-shortening cycle activity to determine if an optimal resistive load exists for complex training. Twelve elite rugby players performed three drop jumps before and after three back squat resistive loads of 65%, 80%, and 93% of a single repetition maximum (1-RM) load. All drop jumps were performed on a specially constructed sledge and force platform apparatus. Flight time, ground contact time, peak ground reaction force, reactive strength index, and leg stiffness were the dependent variables. Repeated-measures analysis of variance found that all resistive loads reduced (P < 0.01) flight time, and that lifting at the 93% load resulted in an improvement (P < 0.05) in ground contact time and leg stiffness. From a training perspective, the results indicate that the heavy lifting will encourage the fast stretch-shortening cycle activity to be performed with a stiffer leg spring action, which in turn may benefit performance. However, it is unknown if these acute changes will produce any long-term adaptations to muscle function. 相似文献
