title: The effect of dietary nitrate supplementation on physiology and performance in trained cyclists

authors: McQuillan, Joseph A.

abstract: Purpose: To determine the effect of dietary nitrate (NO₃⁻) supplementation on physiology and performance in well-trained cyclists following six to eight-days of NO₃⁻ supplementation. Methods: Eight competitive male cyclists (mean ± SD; age = 26 ± 8 y; body mass = 76.7 ± 6.9 kg; VO2peak = 63 ± 4 ml.kg⁻¹.min⁻¹) participated in a double-blind, placebo-controlled, crossover-design study in which participants ingested 70 ml beetroot juice containing ~4 mmol NO₃⁻ (NIT) or a NO₃⁻ depleted placebo (PLA) , each for 8-days. Replicating pre-treatment measures, participants undertook an incremental ramp assessment to determine VO₂peak, first (VT₁), and second (VT₂) ventilatory thresholds on day 6 (NIT6 and PLA6), moderate-intensity cycling economy on day 7 (NIT7 and PLA7), and a 4-km time-trial on day 8 (NIT8 and PLA8). Results: Relative to PLA, 6 days of NIT supplementation produced unclear effects for VO2peak (mean ±95%CL: 1.8 ±5.5%) and VT1 (3.7 ±12.3%) and trivial effects for both VT2 (-1.0 ±3.0%) and exercise economy on day 7 (-1.0 ±1.6%). However, effects for time-trial performance time (0.7 ±0.9%), and power (2.4 ±2.5%), on day 8 were likely beneficial. Conclusions: Despite mostly unclear outcomes for standard physiological determinants of performance, 8-days of NO₃⁻ supplementation resulted in likely beneficial improvements to 4-km time-trial performance in well trained male endurance cyclists.

title: Publishing cooperative and work-integrated education literature: The Asia-Pacific Journal of Cooperative Education

authors: Zegwaard, Karsten E.

subjects: Citations

abstract: The Asia-Pacific Journal of Cooperative Education (APJCE) was founded in 1999, with the first volume published in 2000. The journal strongly adhered to the philosophy of having freely and readily accessible information, and opted to be a free, fully online, open access journal. Over the last 12 years, the journal has grown and has become well-established in the cooperative (co-op) and work-integrated learning (WIL) community. The number of publications per year has steadily increased and the number of submissions has shown strong growth, especially in the last three years. APJCE articles are increasingly cited in other journals and significant book publications, and both its author and user bases have become more international. This article will discuss the advantages from the APJCE perspective of being an open access journal and provide an analysis of the growth of APJCE. The article will also discuss the performance of the journal in the context of co-op/WIL literature internationally and discuss some recent developments for the journal.

title: Indigenous cancer research: Reflections on roles and responsibilities

authors: Scott, Nina

abstract: When asked for a commentary on the roles and responsibilities of nonindigenous researchers in indigenous cancer research, several potential nonindigenous coauthors were contacted. The majority wanted to “run for the hills,” signifying that many researchers feel uncomfortable, out of their depth, and fearful regarding methodologies and principles for safe and effective research with and for indigenous peoples.

Most health research is relevant for indigenous peoples, and most researchers are nonindigenous. Thus, if researchers don’t engage with indigenous research principles, health research can and does result in significant harm for indigenous peoples.1,2 Nonengagement may also prevent potential positive outcomes for indigenous communities (eg, health gain, workforce and community development) and impinge on indigenous rights to health and development.3

In this commentary, we outline our reflections and observations on the roles and responsibilities of nonindigenous cancer researchers and identify some of the principles that guide researchers in Aotearoa (Aotearoa is the name given by the indigenous Māori for New Zealand). We do not attempt to provide an in-depth analysis or comprehensive best practice summary, but hope to encourage more discussion in this critical and evolving area.
