Assessing preschool children's physical activity: the Observational System for Recording Physical Activity in children-preschool version

In this paper we present initial information concerning a new direct observation system-the Observational System for Recording Physical Activity in Children-Preschool Version. The system will allow researchers to record young children's physical activity levels while also coding the topography of their physical activity, as well as detailed indoor and outdoor social and nonsocial contextual information. With respect to interobserver agreement (IOA), the kappa and category-by-category agreement mean of those obtained for the three illustrative preschools were generally above .80. Hence, our IOA data indicated that trained observers in the three preschools frequently agreed on the eight observational categories and accompanying codes. The results for preschoolers' level of physical activity indicated they spent the majority of observational intervals in sedentary activity (i.e., more than 80% intervals) and were observed in moderate to vigorous physical activity much less frequently (i.e., 5% or fewer intervals). For the 15 indoor and 12 outdoor activity contexts, variability across both the activity contexts and the three preschools were evident. Nevertheless, three classroom contexts-transition, snacks, and naptime--accounted for the greatest porportion of coded activity contexts for the children. In the three preschools, 4 of 17 physical activity types--sit and squat, lie down, stand, and walk--accounted for the topography of much of children's physical activity behavior Systematic observation of more representative preschool samples might better inform our present understanding of young children's physical activity in community preschool programs.     

Gendered performances and identity construction among UK female soccer players and netballers: a comparative study

This paper examines the gendered performances and identity construction of UK female University soccer players and netballers (n?=?31). Focus group interviews explored their sporting experiences with reference to body perceptions, and perceptions of their sporting bodies outside sporting contexts. Three themes resulted from data analysis, these being; (1) UK culture, body performances and femininity, (2) sporting culture, body performances and femininity and (3) transiency of body satisfaction across sport and non-sport contexts. Findings suggest that sport may not always provide an opportunity to challenge and resist dominant discourses. In both netball and soccer, a range of surveillance and management practices were used that served to perpetuate the value of a ‘feminine’ and assumed heterosexual body, and legitimize their sport participation through an emphasis on a hyper-femininity. The influence of sport subcultures on gendered performances and identity construction, along with implications for marketing sports participation to women are discussed.     

Biomechanical differences between left- and right-handed baseball pitchers

Left-handed baseball pitchers are thought to have a number of theoretical advantages compared to right-handed pitchers; however, there is limited scientific research detailing differences in the pitching mechanics of right- and left-handed pitchers. Therefore, this study sought to understand whether any kinematic and kinetic differences existed between right- and left-handed baseball pitchers. A total of 52 collegiate pitchers were included in this study; 26 left-handed pitchers were compared to 26 age-, height-, weight- and ball velocity-matched right-handed pitchers. Demographic information, passive shoulder range of motion and kinematic and kinetic data were obtained for each pitcher participating in the study. Results indicated that left-handed pitchers did not have a glenohumeral internal rotation deficit as compared to right-handed pitchers. Kinematic analysis indicated that elbow flexion, horizontal glenohumeral abduction and wrist coronal plane motion were significantly different between the two study cohorts. It was also noted that left-handed pitchers had increased elbow varus moments. The findings of this study suggest that pitching coaches should be aware that there are biomechanical differences between left- and right-handed pitchers.     

Impact of Virtual Work Environment on Traditional Team Domains

An extensive literature review and a phenomenological heuristic case study examined a virtual work team to determine what were salient domains of the team and determine the effect the virtual work environment had upon these domains. The study determined that post‐modern philosophy and postindustrial society are linked to changes in the marketplace and the development of virtual work environments. Seven team domains were identified. The virtual work environment affects the communication domain of teams most strongly. This effect impacts the remaining domains. Decision processes were determined to be narrower and featured conformity. Effectiveness was shown to be diminished by the reduction of social facilitation and increase in social loafing. Leadership was affected by the change in the communication network from an all‐channel network to a wheel network. Relationship and trust were affected by erosion of trust. Roles changed with the team's reduced ability to resolve differences and execute detailed action. Purpose became more task‐oriented. Technology emerged in the study as the new virtual team domain. Factors involved in team members' satisfaction were related to personality, isolation, and team membership.     

Tutoring interventions within special education settings: A comparison of cross-age and peer tutoring

In two experiments, cross-age and peer tutoring interventions conducted within special education settings were compared. In Experiment 1, learning disabled (LD) and behaviorally disordered (BD) students acted as tutors of younger LD and BD students. In Experiment 2, same-age LD and BD students alternated tutor and tutee roles. In both experiments, tutors and tutees exhibited academic gains. Only in Experiment 1, however, were attitudinal gains observed. Implications for future research and practice are given.
