- Description: The aim of this study is to investigate the effects of in-game physical exertion on decision-making performance of Australian football umpires. Fifteen Australian football umpires (Mage = 36, s = 13.5 years; Mgames umpired = 235.2, s = 151.3) volunteered to participate in the study. During five competitive Australian football pre-season games, measures of in-game physical exertion (blood lactate levels, global positioning system [GPS]) and decision-making performance (video-based test) were obtained. There were no significant correlations between physical exertion in a particular quarter and decision-making performance in either the same quarter or any other quarter. Video-based decision-making performance was effected by time in game χ2(3) = 24.24, P = 0.001, with Quarter 4 performance significantly better than both Quarter 2 and Quarter 3. In-game physical exertion (blood lactate) significantly decreased over the course of the game χ2(3) = 11.58, P = 0.009. Results indicate no definable link between in-game physical exertion and decision-making performance. It is, however, presumed that decision-making performance may be affected by the time or context of the game. Future research is warranted to explore the relationship between physical exertion and decision-making performance to potentially inform Australian football umpire training programmes that replicate in-game physical and decision-making demands.

- Description: This study determined if small-sided games could discriminate perceptual-cognitive-motor skill in Australian Rules Footballers. Higher skilled Western Australian Football League (WAFL) (n = 17) and lesser skilled Amateur (n = 23) players were recruited. Participants played three small-sided games of three minutes. Each disposal was scored for decision-making and motor skill execution, with these scores combined for a total score. Mann-Whitney U tests indicated significantly superior mean decision-making by higher skilled (Median = 2.90, Range = 0.30) over lesser skilled (Median = 2.80, Range = 0.73) (p = .012) players. Execution score was not significantly different between groups. Linear mixed model analysis found higher skilled players (M = 5.32, SD = 1.19) scored significantly higher than lower skilled players (M = 4.90, SD = 1.52) on total score (p = .009). Large effect sizes were found for decision-making and total score relative to games and position played in WAFL players. High agreement of scoring was observed for an elite (inter-rater) and a novice (intra-rater) coaches. Linear mixed model analysis indicated mean total scores of WAFL players significantly predicted disposal efficiency in match performance (p = .011). Small-sided games can be easily implemented to identify talented players and assess perceptual-cognitive-motor skill. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.
‘I walk from trouble’ : exploring safeguards with adults with intellectual disabilities – an Australian qualitative study

- Description: People living with intellectual disabilities have a right to be safe from abuse and neglect and have a right to be included in the decision-making process determining safeguards that will affect them. However, the research evidence that could underpin good professional practice in terms of co-producing safeguards against abuse and neglect directly involving people with intellectual disabilities is largely missing. This article, based on qualitative research involving semi-structured interviews conducted during the first half of 2014, seeks to strengthen this evidence base. It reports on the prevention strategies identified by 12 adults with intellectual disabilities about how to stay safe and compares these with the findings of similar research. The article suggests that a comprehensive safeguarding approach comprises both life course-focused safety training and access to assisted decision-making. The article argues that given the plethora of risk situations encountered by people living with intellectual disability, assisted decision-making should take the form of a co-creation process that is situation specific and grounded in everyday life. © 2016 Taylor & Francis.

- Description: Using pedagogical confrontations as a lens for a study of teacher educator work, we identify the way that teacher educator practice is mediated by teacher educator values and beliefs. We highlight the ways that an examination of these confrontations provides greater understanding of the pedagogy, practice, and decision-making of teacher educators and contend that analysis of practice is vital to revealing the complexity of teacher educator work. © 2023 Kappa Delta Pi.

- Description: Video-based training is a commonly used method to develop decision-making in athletes and officials. This method typically uses match broadcast footage, yet technological advancements have made 360° Virtual Reality (360°VR) a possible effective tool to investigate. This study aimed to investigate the effectiveness of both 360°VR and match broadcast footage on improving decision-making. Amateur Australian football umpires (N= 32) participated in a randomised control trial. Participants completed a 5-week training intervention in either a 360°VR, match broadcast or control group. Decision-making was assessed at pre-training, 1-week post-training and 4-week retention points using reliable and valid 360°VR and match broadcast decision-making tests. Participants completed a short questionnaire detailing their perceptions of psychological fidelity, enjoyment, relevance, concentration and effort for each video mode. The 360°VR performed significantly better (p < 0.05) than the control group in the 360°VR retention test. No groups statistically improved over the intervention. Remaining pairwise comparisons for this test and the match broadcast test were not significantly different. 360°VR was rated significantly higher (p < 0.05) than match broadcast footage for psychological fidelity, enjoyment and relevance. 360°VR appears to be a beneficial training tool compared to a control, with stronger engagement from the participants than previously used match broadcast footage.
