title: Advocates for teaching: Reconceptualising the practice of teaching development in a university

authors: Spiller, Dorothy

subjects: valuing teaching

abstract: Teaching development units have been provided at most Australasian and British universities over the last thirty years. Typically, units have provided workshops, courses and individual consultations in a variety of formats. These units have always attracted enthusiasts, but have often struggled to bring about a fundamental shift in organisational thinking about teaching. At the same time, external pressures such as Performance Based Research Funding (PBRF) draw academics away from teaching concerns and create additional challenges for staff developers.

title: The relationship between physiological and performance variables during a hot/humid international rugby sevens tournament

authors: Fenemor, Stephen Paul

subjects: Science & Technology

abstract: Purpose: To characterise core temperature (Tc) along with predictors of Tc during an international rugby sevens tournament played in hot/humid conditions. 

Methods: Tc was collected from 11 elite men’s rugby sevens athletes (age 24 ± 3 years) competing in the Oceania sevens tournament in Suva, Fiji. Game specific external load data [playing minutes, total running distance, high speed running distance (HSD)], psychrometric wet bulb temperature (WBTp) and exertional heat illness (EHI) symptoms were also collected. Cohen’s effect sizes (d) were used to assess differences in Tc across measurement periods was, while linear regression was used to assess the effect of external load and post warm-up Tc on peak game Tc.
 
Results: Compared to baseline on both tournament days, mean Tc was higher at all subsequent time-points, including between games (all d > 1.30). On both tournament days, eight athletes (~73%) reached a peak game Tc > 39.0 °C. with several athletes reaching > 39.0 °C during warm-ups. The final game of the tournament recorded the highest mean peak Tc (39.1 ± 0.3 °C). Mean Tc was related to playing minutes, total running distance, HSD, and post warm-up Tc (all p < 0.01). 

Conclusions: Tc during warm-ups and games regularly exceeded those demonstrated to be detrimental to repeated sprint performance (> 39 °C). Warm-up Tc represents the easiest predictor of game peak Tc to control via the use of appropriate pre- and per-cooling strategies. Practitioners should be prepared to modulate warm-ups and other heat preparation strategies based on likely environmental conditions faced in these tournaments.

title: Boat electrofishing salvage of fish in the Lower Mangamahoe Dam reservoir

authors: Hicks, Brendan J.

abstract: The aim of the survey was to salvage fish from the Lower Mangamahoe Dam reservoir before dewatering and dam removal. We used the University of Waikato’s 4.5 m-long, aluminium-hulled electrofishing boat to catch a total of 140 fish weighing an estimated 37.0 kg along 8 fishing tracks sites on 24 February 2022. These tracks comprised 2,807 lineal m and 11,228 m2 in area. Shortfin eels (Anguilla australis) and common bullies (Gobiomorphus cotidianus) were the only fish species present. Mean density of eels caught was 2.9 fish 100 m–2 and mean biomass was 7.84 g m–2. The eels and bullies were transferred to sites downstream in the Waiwhakaiho River by iwi members of the two hapū - Ngāti Te Whiti and Ngāti Tawhirikura. Water clarity, expressed as black disc distance (BDD, 1.05 m), was good for a shallow lake, and water temperature and water conductivity were close to optimum for electrofishing. Poor water clarity can reduce the efficiency of electrofishing, so we left time after fishing each track for the sediment suspended by the propellor wash to sink before refishing a track.
