Environmental education scholars have argued for the need to focus on identity as a more predictive factor than attitude of individuals’ environmental behavior. We examine individuals’ decision-making as a mediating process between identity and behavior. University undergraduates (N = 299) were surveyed, with a select sub-sample interviewed. As expected, environmental identity was correlated with pro-environment behavior (recycling). However, students with lower pro-environmental identity also recycled regularly. Similarly, analysis of decision-making revealed most students, regardless of their environmental identity, do not think much when recycling. Environmental structures such as presence of recycling bins surfaced as a powerful influence on pro-environment behavior. 相似文献

Abstract Pre-season rugby training develops the physical requisites for competition and consists of a high volume of resistance training and anaerobic and aerobic conditioning. However, the effects of a rugby union pre-season in professional athletes are currently unknown. Therefore, the purpose of this investigation was to determine the effects of a 4-week pre-season on 33 professional rugby union players. Bench press and box squat increased moderately (13.6 kg, 90% confidence limits ±2.9 kg and 17.6 ± 8.0 kg, respectively) over the training phase. Small decreases in bench throw (70.6 ± 53.5 W), jump squat (280.1 ± 232.4 W), and fat mass (1.4 ± 0.4 kg) were observed. In addition, small increases were seen in fat-free mass (2.0 ± 0.6 kg) and flexed upper-arm girth (0.6 ± 0.2 cm), while moderate increases were observed in mid-thigh girth (1.9 ± 0.5 cm) and perception of fatigue (0.6 ± 0.4 units). Increases in strength and body composition were observed in elite rugby union players after 4 weeks of intensive pre-season training, but this may have been the result of a return to fitness levels prior to the off-season. Decreases in power may reflect high training volumes and increases in perceived of fatigue. 相似文献

Abstract The purpose of this study was to investigate differences between the oversized racquet and the standard-sized racquet in (1) a tennis shot accuracy test on four basic strokes (ground strokes, volley, return of serve, and serve), and (2) a measure of players' subjective evaluation of playability (control, accuracy, power, and feel). Research participants (n = 57) were undergraduate students separated into two skill levels, intermediate (n = 29) and beginners (n = 28). Data were analyzed using a two-factor ANOVA with repeated measures on one factor. Result from the skills tests indicated that both beginning and intermediate groups scores significantly higher when using the oversized racquet. The scores received when using the oversized racquet tended to reflect a general increase in all four components of the skill test, particularly the return of serve. Data indicated that the subjective evaluation of the playing characteristic of each racquet was influenced by the player's skill level. Beginning players favored the oversized racquet, yet intermediate players rated the two racquet types about equal. The investigation suggests that beginning and intermediate tennis players, educators, and tennis teaching professionals should consider using and encouraging the use of oversized racquets. 相似文献

Abstract The Sport Orientation Questionnaire (SOQ) was developed as a multidimensional, sport-specific measure of individual differences in sport achievement orientation. Exploratory and confirmatory factor analyses revealed a stable, three-factor structure across three separate samples of university and high school students. The three separate but related subscales of competitiveness, win, and goal orientation demonstrate high internal consistency and stability over time. The SOQ competitiveness score differentiates students in competitive activities from those in noncompetitive activities, providing evidence for construct validity. The overall factor stability, reliability and validity evidence suggests that the SOQ can be a valuable measure for the investigation of competitiveness and achievement behavior in sport and exercise settings. 相似文献

Abstract The primary purpose of this study was to assess perceived and experienced role conflict of high school female athletes in enacting the roles of female and female athlete. Data were collected on 133 high school varsity athletes by the use of a 33-item questionnaire designed to assess perceived and experienced role conflicts of the subjects, their socioeconomic backgrounds, and specific instances of encouragement or discouragement from significant others experienced during their athletic careers. Thirty-two percent of the subjects responded that they perceived little or no problem with role conflict, and 50% had experienced little or no role conflict. Seventeen percent of the subjects responded that they perceived role conflict to be a great or very great problem with 11% experiencing role conflict to the same degree. A chi square analysis of perceived and experienced role conflict computed for the entire group of subjects indicated that the athletes perceived greater role conflict than they had experienced (p<.01). A one way analysis of variance was performed comparing the means of the athletes in traditionally socially approved sports, those in non-traditionally socially approved sports, and those participating in both categories. Results indicated a tendency for those participating simultaneously in both socially approved and non-socially approved sports to have experienced more role conflict (p≤.07). A distinction between internal and external role conflict was suggested as a method of understanding the different types of pressures with which the female athlete must deal. 相似文献

Abstract Two experiments were conducted to investigate the effects of competition and instructional sets on the speed and accuracy of a dart-throwing task. In both experiments individuals competed against another subject on one day, and performed under noncompetitive conditions on a second day. The five distinct instructional sets varied from extreme emphasis on speed to extreme emphasis on accuracy. Multivariate analyses of variance revealed main effects for instructional sets on speed and accuracy in both experiments. Strong tradeoffs occurred with speed slowing and accuracy improving as the instructional emphasis changed from speed to accuracy. A competition by instructional sets interaction in Experiment 2 indicated that competition facilitated speed when speed was important, but when instructions emphasized accuracy, speed was slower in competition than in noncompetition. Accuracy was not affected by competition. 相似文献

Data gathered as part of a recent research project into the provision of collective worship in schools in England and Wales reveals the existence of a marked variation in approach and provision between schools in the primary and secondary sectors. Consequently, the point of transfer often becomes a watershed in pupils’ experience. This sudden change, which is most apparent in community schools, is accompanied by a slower but pre-existing transition in attitudes which is common to pupils in all types of institution. Using material gathered from interviews with young people, this article examines the issue of participation in school worship from the pupils’ perspective and analyses the reasons they give for their opposition to provision. It then compares these attitudes with those of a previous generation, as demonstrated in the work of Loukes (1961) and Goldman (1964, 1965) in order to explore the underlying changes which influence students’ thinking. It concludes with a consideration of the implications of these findings for practice and policy. 相似文献

This article reports on how a small group of New York City adolescents interpreted audio‐visual expressions that were created by youth participating in the international VideoCulture Project. The New York City youth looked for explicit messages in the youth‐produced video films, but also appreciated features of content and form that prompted their curiosity about the youth producers’ intent, as well as experience of everyday life. This study suggests how American culture has influenced these youth's sensibilities about audio‐visual communication, and discusses the value and problems of engaging youth in projects of this nature 相似文献
