title: Application of a nutrition support protocol to encourage optimisation of nutrient intake in provincial academy rugby union athletes in New Zealand: Practical considerations and challenges from a team-based case study

authors: Roberts, Charlie J.

abstract: Provincial academies represent an important bridge between amateur and professional level rugby union in New Zealand. Athletes are provided with professional-level coaching; however, limited direct nutrition support is available. Congested training schedules and the requirement to work or study due to a lack of financial support may present a challenge towards athletes meeting nutrition requirements. The aim of the study was to facilitate improvement in nutrient intake, body composition and subjective well-being in provincial academy athletes via the implementation of a nutrition-support protocol based around behaviour change techniques. Significant increases in total energy (pre: 2492 ± 762 kcal; post: 2614 ± 625 kcal), relative energy (pre: 24.4 ± 7.5 kcal·kg; 25.5 ± 6.0 kcal·kg), total protein (pre: 131.1 ± 41.8 g; 153.8 ± 37.1 g) and relative protein (pre: 1.3 ± 0.4 g·kg; post: 1.5 ± 0.3 g·kg) were observed. Furthermore, changes in subjective sleep quality, stress, mood and upper body soreness were observed following the intervention. No changes were observed in body composition, carbohydrate or fat intake. Significant variability in nutrition and body composition changes highlights the importance of applying an individualised approach to nutrition support provision in developmental athletes. Practitioners working within these environments should be aware of the challenges and influences contributing to athletes’ nutrition choices and habits.

title: Transport of cross helicity and radial evolution of alfvenicity in the solar wind

authors: Matthaeus, William H.

subjects: mathematics

abstract: A transport theory including cross helicity, magnetohydrodynamic(MHD) turbulence, and driving by shear and pickup ions, is applied to the radial evolution of the solar wind. The radial decrease of cross helicity observed in the solar wind can be accounted for when sufficient driving is included to overcome the inherent tendency for MHD turbulence to produce Alfvenic states.

title: Editorial for “Unmasking Racism and Oppression in Psychology” – Part II

authors: Tan, Kyle K. H.

abstract: Since publishing the first part of the “Unmasking Racism and Oppression in Psychology” special issue in March 2025, we have received immense aroha and gratitude from colleagues and students eager to learn about the perspectives of Indigenous and minoritised groups in psychology and how they can support the development of an anti-racist discipline. Rather than seeking to prove the existence of racism in the field (Crossing et al., 2024), this issue centres on validating our authors’ experiences of navigating oppression, challenging Eurocentric psychology, resisting assimilation, and remaining grounded in Indigenous ontologies and epistemologies while staying accountable to their communities. Racism in psychology has been called out by many colleagues in Aotearoa (to name a few; Levy & Waitoki, 2016; Love, 2008; Pomare et al., 2021), and this issue responds to their concerns by amplifying solutions for change in the teaching, practice, and research of psychology.
