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

This study investigated the acute endocrine responses to a 164-km road cycling event in a hot environment. Thirty-four male experienced cyclists (49.1 ± 8.3 years, 86.8 ± 12.5 kg, 178.1 ± 5.1 cm) participating in a 164-km road cycling event were recruited. Blood samples were collected within 0.3–2.0 h before the start (PRE: ~0500–0700 h) and immediately following the ride (POST). Samples were analysed for testosterone, growth hormone (GH), cortisol and interleukin-6 (IL-6). The temperature and humidity during the event were 35.3 ± 4.9°C and 47.2 ± 14.0%, respectively. Based on the finishing time, results for the fastest (FAST, 305 ± 10 min) and the slowest (SLOW, 467 ± 31 min) quartiles were compared. At POST, testosterone concentration was significantly (P < 0.05) lower (PRE, 20.8 ± 8.6; POST, 18.2 ± 6.7 nmol · L?1), while GH (PRE, 0.3 ± 0.1; POST, 2.3 ± 0.3 µg · L?1), cortisol (PRE, 661 ± 165; POST, 1073 ± 260 nmol · L?1) and IL-6 (PRE, 4.0 ± 3.4; POST, 22.4 ± 15.2 pg · mL?1) concentrations were significantly higher than those at PRE. At POST, GH and cortisol were significantly higher for the FAST group than for the SLOW group (GH, 3.6 ± 2.0 and 1.0 ± 0.8 µg · L?1; cortisol, 1187 ± 209 and 867 ± 215 nmol · L?1). Participation in an ultra-endurance road cycling event in a hot environment induced significant acute changes in concentrations of circulating hormones, with a greater augmentation of GH and cortisol in those completing the ride fastest.  相似文献

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.  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

In recent years, there has been a wealth of research into how the game of association football developed. However, rather than establishing a common theme this research has led to competing theories with the debate dividing opinion on how the game of football was developed and propagated. While debate is healthy, the approach taken by some could lead to fellow academics looking to those engaged in sport history as unprofessional. This paper seeks to propose a way forward with academics working towards an all-encompassing history of the sport, by suggesting the adoption of a framework based on the work of Fernand Braudel, where indepth analysis of individual events is combined with the identification of transformational cycles. The paper concludes by suggesting that historians interested in soccer’s early history work together within the framework to develop a more detailed and all-encompassing early history of the sport. This framework will not claim that either the orthodox or revisionist view is accurate, instead it will determine how best to work those debates into an all-encompassing approach while searching for detailed evidence on what was actually occurring at local levels.  相似文献

The academic award restructuring of 1991 established a trial period for academic staff appraisal for the purposes of staff development. The trend in Australia towards more formal performance management for academics has occurred during a period of substantial change to the structure of higher education and institutional management, and brought debate on whether appraisal, for either summative purposes (where performance assessment is for remuneration or promotion purposes) or formative purposes (where the emphasis is on planning personal development), is appropriate for academic staff. Arguments have been put forward for the benefits of appraisal processes with primarily developmental intent. Thus far there have been reports of the characteristics and processes of appraisal schemes, but less data on outcomes; in particular, little evidence to indicate the extent to which schemes lead to worthwhile staff development. This paper reports selected findings of a study of the evolving appraisal scheme of The University of Melbourne. The study was conducted after the scheme's second year of operation by the Centre for the Study of Higher Education which played an advisory role in an internal review of the scheme. The findings reveal some uncertainty among staff about the intentions of the scheme, and tensions between summative and formative purposes, perhaps not surprising given the contentious issue which staff appraisal has been in higher education. Nevertheless, positive outcomes were identified, but possibly too few to claim that the scheme was fully achieving a developmental objective. These findings raise questions about the effectiveness of academic staff appraisal nationally and suggest that it is time to reconsider the policy linkage between appraisal and staff development.  相似文献
