The British Journal of Educational Technology (BJET) uses a novel system for obtaining referees by e‐mailing the abstracts of submissions to a panel of over 250 referees and allowing these individuals to choose which papers they would like to review. An analysis of 13 experienced referees showed that, of 473 reviews assessed, these referees were slightly more lenient than the editor and that electronic records provide useful data that can be mined in interesting ways.  相似文献

Though there is a long tradition of band members quitting the group or taking a hiatus, the rock group as an organization to produce music continues to be both popular and economically viable. The research question addressed in this paper is whether or not it is a good idea to quit or take a hiatus from the group. We begin with a discussion of the framework for understanding why groups are formed and why they may be difficult to keep together. We then discuss differences between groups in the decade of the 1960s versus today. We argue that there is something unique about the output of the group even with the changes in the structure of contracts, compensation, and consumer focus on the artist that explain the resilience of the rock band as an organizational form within which to create music. We compare the charting success of bands that have members leave the group with the charting success of the members who left the group. We identified the groups in five representative years: 1965, 1975, 1985, 1995, and 2005. We then analyzed the entire Billboard Hot 100 charting careers of those groups and the artists who quit those groups. Our main finding is that when charting success is divided equally among members, going solo pays off—there is a clear economic rationale because solo acts have greater average charting success than the original bands they started in. The other ensuing side projects: duos, collaborations, and other groups are not as lucrative as the original bands. These findings are valid for members of charting groups from each of the 5 years examined. Despite the difficulties in keeping a rock band together, there are fewer band breakups today and remaining with the group generally results in a longer and more productive charting career. Thus, the rock group remains an important organization for producing contemporary music. However, there remains a compelling incentive to go solo. Superstars may benefit from solo projects, but for the average, non-superstar group member, in many circumstances it is better for the band to stay together if the income is divided equally.  相似文献

This study investigated the combined role of instructor communication variables (nonverbal immediacy and self-disclosure), instructor credibility (competence, caring, and trustworthiness), and student personality traits (extraversion, neuroticism, agreeableness, conscientiousness, and openness) in predicting students’ uncivil behaviors in class. A total of 406 students completed online questionnaires regarding the instructor of the class they attended prior to the one in which the study was administered. Personality and instructor behavior variables contributed approximately equally to explaining variance in student incivility. Students’ conscientiousness and agreeableness had direct negative relationships with incivility, whereas instructors’ amount and negativity of self-disclosure had direct positive relationships with incivility.  相似文献

This study examined whether perceived message effectiveness (PE) predicted information-seeking behavior in the topical domain of colon cancer. Participants (N = 277) viewed one of three video messages (news, testimonial, and animation) that advocated screening for colon cancer. Information-seeking behavior was operationalized as reading time for a subsequent message about colon cancer. The proposed mediation model successfully reproduced the pattern of data, thereby providing evidence that PE predicts behavior via intention.  相似文献

Teacher performance evaluation currently is receiving unprecedented attention from policy makers, scholars, and practitioners worldwide. This study is one of the few studies of teacher perceptions regarding teacher performance measures that focus on China. We employed a quantitative dominant mixed research design to investigate Chinese teachers’ preferences for teacher performance measures and the possible reasons for their preferences. Considering the quantitative results, the surveyed Chinese teachers identified fulfillment of additional roles, collaboration with faculty and staff, and students’ test scores as the most important measures for performance evaluation. Qualitatively, the most important measures that the surveyed teachers reported were the teacher’s morality, workload, and students’ test scores.  相似文献

The development of a comprehensive protocol for quantifying soccer-specific skill could markedly improve both talent identification and development. Surprisingly, most protocols for talent identification in soccer still focus on the more generic athletic attributes of team sports, such as speed, strength, agility and endurance, rather than on a player’s technical skills. We used a multivariate methodology borrowed from evolutionary analyses of adaptation to develop our quantitative assessment of individual soccer-specific skill. We tested the performance of 40 individual academy-level players in eight different soccer-specific tasks across an age range of 13–18 years old. We first quantified the repeatability of each skill performance then explored the effects of age on soccer-specific skill, correlations between each of the pairs of skill tasks independent of age, and finally developed an individual metric of overall skill performance that could be easily used by coaches. All of our measured traits were highly repeatable when assessed over a short period and we found that an individual’s overall skill – as well as their performance in their best task – was strongly positively correlated with age. Most importantly, our study established a simple but comprehensive methodology for assessing skill performance in soccer players, thus allowing coaches to rapidly assess the relative abilities of their players, identify promising youths and work on eliminating skill deficits in players.  相似文献

Abstract

As a phenomenon exogenous to China, the Olympics have been proactively interpreted in the local context since China’s entry (and subsequent re-entry in 1984) into the Olympic movement. With China’s increasing involvement in promoting three bids to host the Olympic Games, two of which were successful, respectively, in 2001 and 2015, the nature of the discourse of key stakeholders in relation to Chinese elite sport has both reflected and reshaped the meaning of the Games to Chinese elite sport. This paper examines the discursive construction process of the Olympics in the Chinese elite sport system by key stakeholders through analyzing statements of political figures on sport and Olympic phenomena, Chinese elite sport policy documents, and the commentaries of leading Chinese sport academics. The analysis of discourse highlights two main features in the construction of the Games in official accounts during the period under investigation. The development of these two themes reflects the nature of the Chinese Olympic discourse, manifests the political power over the interpretation of the Olympics in Chinese context, and continues to characterize the on-going major themes in Chinese elite sport policy.  相似文献
