Kinematics of preferred and non-preferred handballing in Australian football

In Australian football (AF), handballing proficiently with both the preferred and non-preferred arm is important at elite levels; yet, little information is available for handballing on the non-preferred arm. This study compared preferred and non-preferred arm handballing techniques. Optotrak Certus (100 Hz) collected three-dimensional data for 19 elite AF players performing handballs with the preferred and non-preferred arms. Position data, range of motion (ROM), and linear and angular velocities were collected and compared between preferred and non-preferred arms using dependent t-tests. The preferred arm exhibited significantly greater forearm and humerus ROM and angular velocity and significantly greater shoulder angular velocity at ball contact compared to the non-preferred arm. In addition, the preferred arm produced a significantly greater range of lateral bend and maximum lower-trunk speed, maximum strike-side hip speed and hand speed at ball contact than the non-preferred arm. The non-preferred arm exhibited a significantly greater shoulder angle and lower- and upper-trunk orientation angle, but significantly lower support-elbow angle, trunk ROM, and trunk rotation velocity compared to the preferred arm. Reduced ROM and angular velocities found in non-preferred arm handballs indicates a reduction in the degrees of freedom and a less developed skill. Findings have implication for development of handballing on the non-preferred arm.     

Reliability and validity of a GPS-enabled iPhoneTM “app” to measure physical activity

This study assessed the validity and reliability of an iPhone^TM “app” and two sport-specific global positioning system (GPS) units to monitor distance, intensity and contextual physical activity. Forty (23 female, 17 male) 18–55-year-olds completed two trials of six laps around a 400-m athletics track wearing GPSports Pro^TM and WiSpi^TM units (5 and 1 Hz) and an iPhone^TM with a Motion X GPS^TM “app” that used the inbuilt iPhone^TM location services application programming interface to obtain its sampling rate (which is likely to be ≤1 Hz). Overall, the statistical agreement, assessed using t-tests and Bland–Altman plots, indicated an underestimation of the known track distance (2.400 km) and average speed by the Motion X GPS^TM “app” and GPSports Pro^TM while the GPSports WiSpi^TM device overestimated these outcomes. There was a ≤3% variation between trials for distance and average speed when measured by any of the GPS devices. Thus, the smartphone “app” trialled could be considered as an accessible alternative to provide high-quality contextualised data to enable ubiquitous monitoring and modification of programmes to ensure appropriate intensity and type of physical activity is prescribed and more importantly adhered to.     

A mobile knowledge management and decision support tool for soil analysis

This paper describes the implementation and evaluation of a mobile knowledge management and decision support system to assist archaeologists in dealing with soils. Our view is that provision of a mobile tool which provides access to expert knowledge and a means of recording pertinent onsite information will be of great benefit in ensuring crucial information about an excavation is not lost and that the excavation proceeds in an appropriate manner. In this paper we discuss the tool developed, and detail how it has been evaluated via a variety of workshop sessions with likely users, and discussions with advisory groups.     

Routes through higher education: BME students and the development of a ‘specialisation of consciousness’

With changing demographics and the advent of mass higher education, there has been a significant impact on graduate transitions which has led to greater inequalities in access to social support during the transitionary period between undergraduate study and entrance into the labour market. This article explores the experiences of students in their final year of undergraduate study by drawing on 43 interviews with Black and Minority Ethnic (BME) students. Using Bourdieu, we argue that BME students preparing to enter the labour market display a ‘specialisation of consciousness’: a set of practices framed by their prior background and experience, choice of university and the support derived from attending university. ‘Specialisation of consciousness’ is an ongoing process in which BME students identify and understand racial inequalities in higher education and accept the limiting consequences these have on transitions into the labour market or further study.     

Attitudes and Behaviour of Children Toward Peers with Disabilities

The theory of planned behaviour (Ajzen, 1988) was used to examine the relationship between the attitudes and behaviour of primary school children towards peers with physical disabilities included in regular education. The participants were 188 primary school children aged 8 to 12 years. Children's attitudes toward peers with disabilities, their behavioural intentions to interact with and befriend such peers, and the amount of control they perceived having over interactional behaviour, were assessed using self-report measures. These variables were used to predict the amount of time children reported spending with their classmates with physical disabilities in the classroom and playground. The results supported the theory of planned behaviour. Children's attitudes and perceived behavioural control were significant predictors of their intentions to interact with a child with physical disabilities. Intentions predicted actual behaviour to a modest extent, while perceived behavioural control was not directly associated with actual behaviour. The implications of these findings for interventions to change the attitudes and behaviours of students toward classmates with disabilities are discussed.
