title: Effect of an overhead goal on landing error scoring system and jump height measures

authors: Hébert-Losier, Kim

subjects: anterior cruciate ligament

abstract: Objectives: Compare overall Landing Error Scoring System (LESS) scores, risk categorisation, specific LESS errors, and double-leg jump-landing jump heights between overhead goal and no goal conditions. 

Design: Randomised cross-over. 

Setting: Laboratory. 

Participants: 76 (51% male). 

Main outcome measures: Participants landed from a 30-cm box to 50% of their body height and immediately jumped vertically for maximum height. Participants completed three trials under two random-ordered conditions: with and without overhead goal. Group-level mean LESS scores, risk categorisation (5-error threshold), specific landing errors, and jump heights were compared between conditions. 

Results: Mean LESS scores were greater (0.3 errors, p < 0.001) with the overhead goal, but this small difference was not clinically meaningful. Similarly, although the number of high-risk participants was greater with the overhead goal (p = 0.039), the 9.2% difference was trivial. Participants jumped 2.7 cm higher with the overhead goal (p < 0.001) without affecting the occurrence of any specific LESS errors. 

Discussion: Performing the LESS with an overhead goal enhances sport specificity and elicits greater vertical jump performances with minimal change in landing errors and injury-risk categorisation. Adding an overhead goal to LESS might enhance its suitability for injury risk screening, although the predictive value of LESS with an overhead goal needs confirmation.

title: Sports Fans' Evaluations of Sporting Code Innovations

authors: Musgrave, Christopher Rex

subjects: Professional Sport

abstract: Today's professional sports are frequently evolving and changing their design, structure and format. Many such innovations have been spurred on by the opportunity to capitalise financially on new markets and increase profit. This study used both quantitative (survey) and qualitative (depth interviews) methods in order to examine fans' attitudes towards the current state of Rugby Union, Rugby League, Netball, Soccer and Cricket. The findings for Rugby Union concluded that the recent experimental law variations have succeeded in what they were introduced to do. Fans believe that Rugby is more exciting to watch than ever before and that it is now a faster and more attack-focused contest. Fans believe that Rugby League has improved following the introduction of the video referee and in particular by the use of two on-field referees. They believe that it is now a more exciting and faster game. Fans also believe that salary caps are good for Rugby League and help to increase competition and spread the wealth of talent among the teams. Netball fans are excited by possible new innovations and show support for the inclusion of power plays, two point goals, rolling substitutions and increased physical contact. Fans believe that Soccer needs to adopt technology in order to help its officials but they also admire the traditionalism of the code. Surprisingly, fans show support for increasing the sizes of Soccer‟s goals in order to make it easier for teams to score. Fans show support for Twenty20 cricket and seem undeterred by recent match fixing scandals. There is also evident support for the introduction of Beach Cricket to New Zealand. Analysing fans' attitudes towards professional sport's product innovations has led to a final implication and conclusion for the administrators and governing bodies of professional sport. That is, it would be wise to keep the traditional codes and their formats as traditional as possible. However, evolve the same sport in to a completely separate format in order to financially capitalise on different markets. Twenty20 cricket is a perfect example of this.

title: Culture is our business: Issues and challenges for forensic and correctional psychologists

authors: Tamatea, Armon J.

subjects: Science & Technology

abstract: Psychology has made significant advances in the development of more empirical, standardized, and consistent approaches to the prediction, assessment, and treatment of offending behaviour. However, crime occurs in a cultural context. Similarly, forensic and correctional psychology derive from a cultural basis that privileges certain types of knowledge and promotes certain forms of practice that are incommensurate with the outlook and realities of some offenders and their communities. While there is an emerging literature on ethnicity and race in criminal justice psychology, very little research that addresses culture is published. The reasons for this knowledge gap are complex, not least because the worldviews of indigenous and diverse communities do not superimpose neatly onto current best-practice models of risk assessment or offender rehabilitation. Given Australia and New Zealand’s commitment to the involvement and wellbeing of indigenous peoples as well as the shared experience of progressively more pluralistic societies, it is argued that there is a critical need to bring the somewhat disparate domains of forensic psychology and culture into conversation with a view to informing policy and practice. The example of risk assessment is used to illustrate some of the complexities of working with cultural difference. Central to this article is a call for a culturally-engaged and proactive philosophy of practice that embraces the needs of diverse offenders, victims and communities.
