Relational efficacy beliefs in athlete dyads: an investigation using actor-partner interdependence models

The first purpose of this study was to examine the interrelationships among three forms of relational efficacy within performing dyads, namely, self-efficacy, other-efficacy, and relation-inferred self-efficacy. The second objective was to examine the relationships between these efficacy beliefs and athletes' perceptions of their commitment to and satisfaction with their current partnership. Participants were 120 junior tennis players (age, M = 14.30 years, SD = 1.21) performing within 60 intact pairs (i.e., doubles). Results revealed that self-efficacy and other-efficacy were predictive of athlete commitment and satisfaction, respectively. In addition, by utilizing actor-partner interdependence models, partner as well as actor effects were evident. The findings illustrate that relational efficacy beliefs may not only have implications for the individual holding such beliefs, but also for his or her relational partner. Implications for the future study of efficacy beliefs within dyadic contexts are discussed.     

An analysis of the relationship between the linear hammer speed and the thrower applied forces during the hammer throw for male and female throwers

The purpose of this study was to investigate the relationship between the cable force and linear hammer speed in the hammer throw and to identify how the magnitude and direction of the cable force affects the fluctuations in linear hammer speed. Five male (height: 1.88 +/- 0.06 m; body mass: 106.23 +/- 4.83 kg) and five female (height: 1.69 +/- 0.05 m; body mass: 101.60 +/- 20.92 kg) throwers participated and were required to perform 10 throws each. The hammer's linear velocity and the cable force and its tangential component were calculated via hammer head positional data. As expected, a strong correlation was observed between decreases in the linear hammer speed and decreases in the cable force (normalised for hammer weight). A strong correlation was also found to exist between the angle by which the cable force lags the radius of rotation at its maximum (when tangential force is at its most negative) and the size of the decreases in hammer speed. These findings indicate that the most effective way to minimise the effect of the negative tangential force is to reduce the size of the lag angle.     

Between legal requirements and local traditions in school improvement reform in Austria: School leaders as gap managers

The implementation of a new school type has changed the context of school leadership in Austrian lower secondary schools. An interview study with 25 secondary-school leaders was undertaken. The goal of the study was to inquire how school leaders conceptualise their role in the local policy adaptation of a centrally driven reform. The results indicate that school leaders saw themselves as double agents in facing increasing demands from within and without schools for legitimating their work. Neo-institutionalist theory is used for explaining the role of school leaders as gap managers. The concept of gap management is deployed for describing the role of school leaders as balancing multiple and contradictory interests at school and among local actors such as teachers, parents, students, and community partners.

The Emotionally Affected University Student: support from the university community

The study measured the general attitudes towards disability of academics, administrative staff, and students in a small rural University. Respondents were also asked to comment on the nature of support that might be provided for a student with an emotional disability. There were some significant differences in level and nature of support for students with an emotional disability among academics, administrative staff, and students. These differences were related to the levels of comfort with, and sympathy felt towards, students with an emotional disability. However, overall the results suggest that university students with expressed emotional difficulties are liable to be relatively negatively regarded and are not liable to receive much concrete assistance for the difficulties they face. It is proposed that the data supports the notion that academics, of all the groups measured, are best placed to decide types of support for students with an emotional disability on a case by case basis.
