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: Social information behaviour in physical libraries: Implications for the design of digital libraries

authors: Hinze, Annika

subjects: Science & Technology

abstract: Physical bookshops and libraries are visited by both individuals, and groups of patrons, while digital libraries are designed primarily for individual users. This paper reports on a study exploring the behaviour of groups of patrons in physical libraries, detailing their collaboration and communication during book searches. We aim to identify how characteristics such as location, time, environment, ambiance, layout and personal motivation play a role in a group's search and browsing behaviour. We report the findings of observations of group collaboration in academic and public libraries, and compare the observed book and library use techniques employed by patron groups. Further, we examine the support for group collaboration in digital libraries and discuss the implications of our observations for the design of digital libraries that support group collaboration and interaction among users. To that end, the paper suggests features and functions that could be added to DLs to enable asynchronous group communication and interaction.

title: Creating a curriculum for indigenous and community languages: Te reo Māori as an example

authors: Bruce, Ian

subjects: linguistics

abstract: Part 1 of this paper introduces the draft Common European Framework of Reference (CEFR) for languages and describes how it was used in the construction of draft New Zealand curriculum guidelines for French and German. Part 2 discusses how the CEFR has been employed in curriculum development in Te Reo Māori at the University of Waikato and suggests that it could also prove useful in relation to curriculum development projects involving indigenous and community languages more generally.
