Two decades ago, Alexander George observed a growing gap between academic theorists and practitioners in the formulation of foreign policy. The significance of the gap has been debated, but trends in the academy, society, and government suggest it is likely to grow.  相似文献

The main purpose of this study was to examine whether the use of internal imagery would affect high jumping performance for active high jumping athletes. Over a period of six weeks, a group of active high jumpers were trained with an internal imagery program for a total of 72 minutes. This group was compared to a control group consisting of active high jumpers that only maintained their regular work-outs during the same time period. Four variables were measured; jumping height, number of failed attempts, take-off angle, and bar clearance. There was a significant improvement on bar clearance for the group that trained imagery (p < 0.05) but not for the control group. No other differences were found. The results suggest that internal imagery training may be used to improve a component of a complex motor skill. Possible explanations and future recommendations are discussed.  相似文献

Individual coping is identified as an important factor in relation to health and well-being. Although several coping scales have been developed, key terms of coping such as nature and a number of primary and secondary factors (dimensions) are obscure. Coping scales, such as those that have been developed through exploratory factor analysis (EFA), have been criticized for poor psychometric properties, yet the critique so far does not evaluate development of the scales against best test-theoretical practice. The present study reviews six adolescent coping scales against ten detailed psychometric criteria in relation to statistical choices throughout the process of scale development. All six scales measured poorly on several criteria. Best practice had not been followed throughout their development and they suffered serious psychometric limitations. These findings indicate that there still is empirical research to be pursued in search of latent constructs and possible dimensions of coping through the implementation of EFA.  相似文献

This paper compares the statement ‘Mathematics is the study of structure’ with the actual practice of mathematics. We present two examples from contemporary mathematical practice where the notion of structure plays different roles. In the first case a structure is defined over a certain set. It is argued firstly that this set may not be regarded as a structure and secondly that what is important to mathematical practice is the relation that exists between the structure and the set. In the second case, from algebraic topology, one point is that an object can be a place in different structures. Which structure one chooses to place the object in depends on what one wishes to do with it. Overall the paper argues that mathematics certainly deals with structures, but that structures may not be all there is to mathematics. I wish to thank Colin McLarty as well as the anonymous referees for helpful comments on earlier versions of this paper.  相似文献

In this exploratory study, we investigated whether or not people who stutter (PWS) show motor practice and learning changes similar to those of people who do not stutter (PNS). To this end, five PWS and five PNS repeated a set of non-words at two different rates (normal and fast) across three test sessions (T1, T2 on the same day and T3 on a separate day, at least 1 week apart). The results indicated that PWS and PNS may resemble each other on a number of performance variables (such as movement amplitude and duration), but they differ in terms of practice and learning on variables that relate to movement stability and strength of coordination patterns. These findings are interpreted in support of recent claims about speech motor skill limitations in PWS.

Educational objectives: The reader will be able to: (1) define oral articulatory changes associated with motor practice and learning and their measurement; (2) summarize findings from previous studies examining motor practice and learning in PWS; and (3) discuss hypotheses that could account for the present findings that suggest PWS and PNS differ in their speech motor learning abilities.  相似文献

It has become almost a truism to describe the interaction between research ethics committees and researchers as being marred by distrust and conflict. The ethical conduct of researchers is increasingly a matter of institutional concern because of the degree to which non-compliance with national standards can expose the entire institution to risk. This has transformed research ethics into what some have described as a research ethics industry. In an operational sense, there is considerable focus on modifying research behaviour through a combination of education and sanctions. The assessment of whether a researcher is ‘ethical’ is too often based on whether they submit their work for review by an ethics committee. However, is such an approach making a useful contribution to the actual ethical conduct of research and the protection of the interests of participants? Does a focus on ethical review minimise institutional risk? Instead it has been suggested that ethics committees may be distorting or frustrating useful research and are promoting a culture of either mindless rule following or frustrated resistance. An alternative governance approach is required. There is a need for a strong institutional focus on promoting and supporting the reflective practice of researchers through every stage of their work. By situating research ethics within the broader framework of institutional governance, this paper suggests it is possible to establish arrangements that actually facilitate excellent and ethical research.  相似文献

Abstract: Over the past 10 years a European standard for psychology education and training (EuroPsy) in Europe has been developed through two European Union (EU)‐funded projects. This development has been supported by political initiatives within Europe, in particular the so‐called Bologna process and the new EU Directive on qualifications, which is intended to facilitate professional mobility. The EuroPsy standard applies to professional psychologists at the initial qualification level, namely, independent practice. It requires 6 years of education and training, which include 1 year of supervised practice. The article describes these developments and some critical issues.  相似文献

Abstract : This essay explores the connection between religious practices and torture with specific reference to the debate in the USA about ‘waterboarding’ as part of the so‐called War on Terror. After isolating some defining features of torture, the essay examines the historical background of waterboarding in the symbolism of Christian baptism and how this symbolism was used during the Inquisition and the Reformation as part of the torture of heretics and others. Mindful of this sordid use of a Christian rite meant to celebrate new life, the essay thereby clarifies Christian responsibility in the political order. That responsibility requires uncovering the religious roots of some forms of torture, resisting their use by the State, and, further, seeking to render current Christian practice both humane and life giving.  相似文献

The purpose of the current study was to explore the use of overt and covert self-rules in the acquisition, maintenance, and generalization of a chained task by adults with mild developmental disabilities. This research differed from previous research in that the experimenter did not deliver reinforcement for correct responses during training, and we examined the correspondence between each self-rule statement and each subsequent response on each trial. Results showed that the self-rules participated in control over participants' responding, in that the skill was acquired and shown to generalize in the absence of experimenter-delivered reinforcement. Moreover, performance was shown to deteriorate when the emission of overt, but not covert, self-rules was blocked.  相似文献
