Gender differences in throwing form of children ages 6-8 years during a throwing game

The study purposes were to describe throwing form and gender differences before and after instruction during a game. Children's (ages 6-8, n = 105) throwing form was assessed while they played a game (snowball) using the Body Component Assessment for Throwing in Games to determine the modal developmental levels for the step, trunk, and forearm components. Each student received four 30-min sessions of throwing instruction. There were significant (p < .017) gender differences at each session and for each component. A Wilcoxon-Signed Ranks Test revealed differences (p < .017) between pretest and after instruction for boys' trunk and forearm components and girls'step and trunk components. The improvement after instruction and gender differences were similar to those found in a controlled, practice context.     

Addressing violence against teachers: A social-ecological analysis of teachers' perspectives

Much research has been dedicated to supporting school communities in combating the problem of school violence. However, violence directed toward teachers is under-investigated, and knowledge of how to support teachers is limited. This qualitative study used conventional content analysis to assess teachers' recommendations for preventing and improving the response to teacher-directed violence. The sample included 245 prekindergarten through 12th grade teachers, all of whom experienced school violence and participated in a larger national survey study on violence against teachers. Using a social-ecological framework and conventional content analysis, teacher recommendations for addressing teacher victimization were identified and organized at the individual, school, community, and society levels. Themes around conflict resolution strategies; improving policies, resources, and relationships with administrators; increasing parental involvement; and changing culture and laws were highlighted. Implications for research, practice, and policy are discussed.     

Business Planning for Higher Education Institutions

Business planning is now an essential discipline for universities, polytechnics and colleges. Those which do not already have a corporate strategy will find they have to develop one in order to succeed in the new funding competition. The skills and attitudes required for successful business planning will have to be acquired and exploited alongside traditional academic strengths. In this article two management consultants who know higher education well explain how institutions can develop and benefit from a structured approach to business planning.     

Succession Planning for Libraries

ABSTRACT

It is imperative for libraries of all types to be responsive to the forecasted changes in the demographics of the library workforce. Succession planning is a key strategy for ensuring that libraries are prepared to meet changing and emerging organizational needs. Succession planning is broadly defined as a range of activities focused on both internal and external talent development to fill anticipated needs for library leadership and other key personnel. The aim of this article is to offer a number of recommendations relevant for LIS education to help build an awareness of succession planning for future library managers. In particular, practical ideas for course-related activities and assignments that may help to incorporate succession planning more fully into the LIS curriculum are discussed.     

Making Space for Storytime: The Role of the Environment in the Production of Storytime

ABSTRACT

This article reviews the findings from Project VIEWS2, a four-year IMLS-funded study that examined the early literacy impact of public library storytimes, and provides detail on a secondary analysis of storytime spaces that was done using the Project VIEWS2 dataset. The storytimes spaces were explored by looking at the spatial quality, physical literacy environment, and seating of attendees, as these characteristics have been identified as important aspects of early childhood learning environments. Findings across these three characteristics are presented as well as implications and recommendations for more effective storytime practice and space design.     

The effect of altered pitch length on performance and technique in junior fast bowlers

The aim of this study was to assess the effect of pitch length (20.12 m [full length], 18 m and 16 m) on the fast bowling performance and technique of junior cricketers. Performance measures included ball release speed and accuracy, while technique variables evaluated were those shown to be related to the aetiology of lower back injury. Thirty-seven fast bowlers from the under-11 (n=14), under-13 (n=11) and under-15 (n=12) age groups were filmed bowling five deliveries at each of the above pitch lengths. Two synchronized NAC video cameras operating at 200 Hz permitted three-dimensional reconstruction of the hip and shoulder alignments, while a standard digital video camera operating at 50 Hz (positioned perpendicular to the bowling action) was used to measure front knee angle and ball release speed. Accuracy scores were taken from a zoned target at the batsman's stumps. A two-way analysis of variance with repeated measures (with age and pitch length as the between- and within-participant variables, respectively) was used to compare each age group at the 0.05 significance level. Results showed that accuracy improved in all age groups at shorter pitch lengths, although ball velocity remained constant throughout all trials. Shoulder counter-rotation increased significantly for the under-13 bowlers when bowling on the full-length pitch in comparison with the two shorter lengths. Counter-rotation also increased on the full-length pitch in the under-11 age group, although this increase was not significant. The under-15 bowlers' techniques did not change as pitch length increased. As under-11 and under-13 bowlers adopted a "safer" bowling action with superior accuracy on the 18?m compared with the full length pitch, it was concluded that these age groups should bowl on an 18?m pitch to reduce the likelihood of lower back injuries and improve accuracy.     

The influence of elbow joint kinematics on wrist speed in cricket fast bowling

This modelling study sought to describe the relationships between elbow joint kinematics and wrist joint linear velocity in cricket fast bowlers, and to assess the sensitivity of wrist velocity to systematic manipulations of empirical joint kinematic profiles. A 12-camera Vicon motion analysis system operating at 250 Hz recorded the bowling actions of 12 high performance fast bowlers. Empirical elbow joint kinematic data were entered into a cricket bowling specific “Forward Kinematic Model” and then subsequently underwent fixed angle, angular offset and angle amplification manipulations. A combination of 20° flexion and 20° abduction at the elbow was shown to maximise wrist velocity within the experimental limits. An increased elbow flexion offset manipulation elicited an increase in wrist velocity. Amplification of elbow joint flexion–extension angular displacement indicated that, contrary to previous research, elbow extension range of motion and angular velocity at the time of ball release were negatively related to wrist velocity. Some relationships between manipulated joint angular waveforms and wrist velocity were non-linear, supporting the use of a model that accounts for the non-linear relationships between execution and outcome variables in assessing the relationships between elbow joint kinematics and wrist joint velocity in cricket fast bowlers.
