Stress in elite sport performers: a comparative study of competitive and organizational stressors

The purpose of this study was to compare the content and quantity of competitive and organizational stressors in elite athletes. Ten international performers were interviewed about sources of stress. Content analysis of the data involved categorizing the demands associated primarily and directly with competitive performance (#CS = 21) under the post hoc dimension "performance issues", and the demands associated primarily and directly with the sport organization (#OS = 72) under one of the following four post hoc dimensions: "environmental issues", "personal issues", "leadership issues" and "team issues". Frequency analysis revealed that the participants mentioned the competitive stressors (sigma = 95) less than the organizational stressors (sigma = 215). Further analysis within these categories showed that the mean number of participants citing individual competitive stressors (M = 4.52) was greater than the mean number of participants citing individual organizational stressors (M = 2.99). The findings indicate that elite athletes experience and recall more demands associated primarily and directly with the sport organization than with competitive performance. Furthermore, this population appears more likely to mention similar competitive stressors but varied organizational stressors, probably because the former are inherent and endemic to elite sport, whereas the latter are essentially extraneous and widely distributed.     

Automatic detection of collisions in elite level rugby union using a wearable sensing device

Elite rugby union teams currently employ the latest technology to monitor and evaluate the physical demands of training and games on their players. Tackling has been shown to be the most common cause of injury in rugby union, yet current player monitoring technology does not effectively evaluate player tackling measurements. Currently, to evaluate measurements specific to player tackles, a time-consuming manual analysis of player sensor data and video footage is required. The purpose of this work is to investigate tackle modeling techniques which can be utilised to automatically detect player tackles and collisions using sensing technology already being used by elite international and club level rugby union teams. This paper discusses issues relevant to automatic tackle analysis, describes a technique to detect tackles using sensing data and validates the technique by comparing automatically detected collisions to manually labeled collisions using data from elite club and international level players. The results of the validation show that the system is able to consistently identify collisions with very few false positives and false negatives, achieving a recall and precision rating of 0.933 and 0.958, respectively. The aim is that the automatically detected tackles can provide coaching, medical and strength and conditioning staff with objective tackle-specific measurements, in real time, which can be used in injury prevention and rehabilitation strategies.     

Relationships between learning environment and mathematics anxiety

We investigated relationships between the learning environment and students’ mathematics anxiety, as well as differences between the sexes in perceptions of learning environment and anxiety. A sample of 745 high-school students in 34 different mathematics classrooms in four high schools in Southern California was used to cross-validate the What Is Happening In this Class? (WIHIC) learning environment instrument, together with an updated Revised Mathematics Anxiety Rating scale. Mathematics anxiety was found to have two factorially-distinct dimensions (namely, learning mathematics anxiety and mathematics evaluation anxiety) which yielded different patterns of results for sex differences and anxiety–environment associations. Relative to males, females perceived a more positive classroom environment and more anxiety about mathematics evaluation, but less anxiety about mathematics learning. Some statistically significant associations were found between anxiety and learning environment scales for learning mathematics anxiety but not for mathematics evaluation anxiety.     

Parental involvement in schooling, classroom environment and student outcomes

We investigated relationships between students’ perceptions of parental involvement in schooling, their Spanish classroom environment and student outcomes (attitudes and achievement). Modified Spanish versions of the What Is Happening In this Class?, Test of Spanish-Related Attitudes-L₁, a parental involvement questionnaire and a Spanish achievement test were administered to 223 Hispanic Grade 4–6 students in South Florida. The factor structure and internal consistency reliability of the questionnaires was supported. Strong associations were found for parental involvement with students’ learning environment perceptions and student outcomes, and for Spanish classroom environment with student outcomes. When the unique and common variances in student outcomes explained by the classroom environment and the home environment were examined, the home environment was more influential than the classroom environment in terms of students’ attitudes, but the classroom environment was more influential than the home environment in terms of achievement.     

THE PRIVATE SCHOOL IN THE AMERICAN SCHEME OF EDUCATION

This article explores the possible contribution to Jewish education found in the resources of Judaica scholarship. It begins by exploring the complex and often uneasy connection between the world of the university and the world of education and then offers an alternative to this tension by suggesting ways that Jewish subject matter scholarship might both help expand Jewish educational research and improve the actual practice of education. Four models are offered as means of implementing these ideas. These models are explored through specific examples and analysis of the potential advantages and challenges embedded in each.     

Toward a Critical Study of Jewish Education

This article proposes a reconfiguration of the academic study of Jewish education that would (1) emphasize the “critical” analysis of an expanded range of issues (2) draw upon a broad range of disciplines and fields of study; and (3) formulate a new research agenda. The article argues that the focus on a “critical” approach to Jewish education studies is not a retreat from practice, but an important step in the enrichment of the academic study of Jewish education, as well as in the enhancement of the practical training of teachers, leaders, and communal professionals.     

DISSERTATION RESEARCH: PART 2, THE QUANTITATIVE DISSERTATION: FORM AND SUBSTANCE

This is the second in a three‐part series of papers concerning dissertation research. In this paper, the elements of quantitative dissertations are identified for analysis and subsequent discussion. Dissertation research should provide the researcher the opportunity to become another example of the generative, creative, and inventive capacity of mankind to be liberated for a period of time from the immediate in order to extend his or her own thoughts forward toward whatever future may be permitted. Dissertation research should provide the reader an opportunity to extend and expand his realm of thought apart from an imposed or artificial conformity to form.
