We evaluate feedback methods for oral presentations used in training non-quantitative research skills (literature review and various associated tasks). Training is provided through a credit-bearing module taught to MSc students of banking, economics and finance in the UK. Monitoring oral presentations and providing ‘best practice’ feedback is very resource-intensive. Do we withdraw oral presentations from the module, because best feedback practice is prohibitively expensive in a world of limited resources, or choose a second-best alternative? To what extent might the latter compromise intended learning outcomes? We used the same provision of video feedback for all students but used two verbal feedback regimes. For one regime, we decreased the amount of verbal feedback and increased the number of presentations. The impact was measured by academic outcome, rating scales and questionnaire. Overall satisfaction with the module was very high for both feedback regimes, and there were no statistically significant differences between regimes, suggesting that less resource-intensive methods need not compromise learning outcomes. 相似文献

Coping with bullying and victimisation among preadolescents: the moderating effects of self-efficacy
Constantinos M. Kokkinos Paraskevi Panagopoulou Ioanna Tsolakidou Evdoxia Tzeliou 《Emotional and Behavioural Difficulties》2013,18(2):205-222
Bullying and victimisation may result from ineffective coping with interpersonal stressors. However, little is known about the preadolescents who are most susceptible to dysfunctional coping styles. Self-efficacy beliefs may be one source of individual differences in coping among those involved in bullying and victimisation. The purpose of the present research was to examine whether links between bullying/victimisation and coping were moderated by self-efficacy beliefs. Participants were 262 Greek preadolescents who completed self-report assessments of bullying/victimisation, coping, and self-efficacy. Results indicated that self-efficacy moderated the association between bullying/victimisation and coping, in that greater use of ineffective coping (i.e., resignation, passive avoidance) predicted bullying and victimisation among preadolescents with moderate and low levels of social and emotional self-efficacy, whereas greater use of adaptive coping (i.e., positive self-instructions, social support) was reported by those with higher self-efficacy beliefs. Practical implications of the findings are discussed. 相似文献

This study aims to introduce a new spectral imaging methodology that can be used to monitor on-line, non-destructively and in situ the cleaning level of pollution encrustation on stonework. The suggested technique is based on the optical properties of monochromatic light penetration in matter. The calculated differences of images, obtained at two different spectral bands, could reliably map the depth of cleaning. This novel approach was tested in the laboratory during laser cleaning trials on polluted stonework enabling high accuracy measurements (such as the detection of thin crust layers remaining on the under-cleaned marble surfaces). However, it may also apply for the monitoring of any other cleaning technique (micro air-abrasive, etc). A detailed presentation of the results will be demonstrated while the potential of its wide application on everyday conservation practice on stonework will be discussed. 相似文献

Media companies are different from manufactures and other commercial organizations. They have both measurable economic goals and nonmeasurable social responsibilities. Leading these companies is a difficult task. The main issue is that an appropriate leadership style for media people must balance business and political goals. In this study, semi-structured interviews were used to collect data about Greek media leaders. The research explores and identifies the leadership style of CEOs heading the top media companies in Greece. These findings indicate that media leaders use a mixed leadership style involving both transformational and transactional styles in order to anticipate the peculiar external and internal media environment. 相似文献

Abstract To determine the time course of performance responses after an acute bout of plyometric exercise combined with high and low intensity weight training, a 3-group (including a control group), repeated-measures design was employed. Changes in performance were monitored through jumping ability by measuring countermovement and squat jumping, and strength performance assessment through isometric and isokinetic testing of knee extensors (at two different velocities). Participants in both experimental groups performed a plyometric protocol consisting of 50 jumps over 50 cm hurdles and 50 drop jumps from a 50 cm plyometric box. Additionally, each group performed two basic weight exercises consisting of leg presses and leg extensions at 90–95% of maximum muscle strength for the high intensity group and 60% of maximum muscle strength for the low intensity group. The results of the study suggest that an acute bout of intense plyometric exercise combined with weight exercise induces time-dependent changes in performance, which are also dependent on the nature of exercise protocol and testing procedures. In conclusion, acute plyometric exercise with weight exercise may induce a substantial decline in jumping performance for as long as 72 hours but not in other forms of muscle strength. 相似文献
