Rugby sevens is a small-sided variant of rugby union characterised by fast-moving, high-intensity gameplay and is an example of a team invasion sport, where players work together to achieve a shared goal of attacking and defending as a cohesive unit. The dynamics of such sports can be viewed as self-organizing systems, where individual players form collective patterns without a centralized mechanism of control. Inspired by the analysis of collective movement in animals, this novel study investigates the emergent patterns of order and disorder in sub-elite female rugby sevens using order parameters (typically used to analyse particle systems) to characterize the team’s collective state during different phases of play. The findings demonstrate that defensive gameplay is more ordered, with more compact formations, compared to attacking play, and there is a correlation between alignment/order in player motion and group speed. The work further suggests that the collective states formed differ between sequences of play with different levels of ground gained by the attacking team. These observations provide a sound justification for player training with a focus on cohesive defensive movements to resist disruptions from opposing attackers, while employing attacking tactics that disrupt the cohesion and order of opposing teams.

Objectives: Prostate cancer (PCa) patients often experience depression. One possible buffer against stress‐related depression is psychological resilience (PR), which has been described as heterogeneous in structure, like major depressive disorder (MDD). Although both of these constructs are central to understanding and assisting distressed PCa patients, no data have been reported on how they connect via network arrays at a component and symptom level. Such information has the potential to inform clinical practice with depressed PCa patients. Methods: Using a cross‐sectional design, 555 PCa patients completed the Patient Health Questionnaire‐9 (PHQ‐9) and the Connor–Davison Resilience Scale (CDRISC). Data were analysed via network analysis. Results: Network analysis indicated that various CDRISC factors interacted with different PHQ‐9 symptoms. For example, trust in one's instincts, tolerance of negative affect, and strengthening effects of stress (CDRISC) was associated with concentration problems and suicidal ideation (PHQ‐9); positive acceptance of change, and secure relationships (CDRISC) was linked to low self‐worth, anhedonia, fatigue/lethargy, motor problems, depressed mood, and concentration and appetite problems (PHQ‐9). Similarly heterogeneous associations were found between individual CDRISC items and PHQ‐9 symptoms. Network analytic figures depict both these sets of associations. Conclusions: As well as confirming the heterogeneous nature of PR and MDD in PCa patients, these findings argue for the further development of ‘individualised’ medicine approaches when working with PCa patients and their experiences of depression.

The concept of noticing, which emphasizes the role of attention and awareness in language learning, has exerted a strong influence on second language acquisition (SLA) theory and practice. The current research analyzes instances of noticing evident across a 26‐week period as the first author, an absolute beginner, was taught Turkish by the second author, a native speaker. All 52 video‐conferenced one‐to‐one lessons were recorded and subsequently thematically analyzed for the learner's noticing of the accusative, dative, locative, and ablative cases at two levels of complexity (single or multiple affix). Six noticing themes were evident and are defined and exemplified with multimodal vignettes and presented as a generalized model. Trends in the occurrence of these noticing themes over the first 6 months of learning are also presented. Discussion focusses on the practical relevance of the types of noticing observed and concludes with directions for future research.

Context. Environmental water is often used to manage floodplain wetlands that support many taxa, both terrestrial and aquatic. It is important to optimise the managed hydroperiod to maximise the provision of aquatically derived resources from wetlands. Aims. To test the hypothesis that increasing hydroperiod affects food-web structure and energy production in floodplain wetlands. Methods. Fatty acids and stable isotopes of δ¹³C and δ¹⁵N were used to define food-web structure, and estimate total energy production throughout a managed inundation event in a wetland in the northern Murray–Darling Basin. Key results. Food-web complexity increased with an increasing hydroperiod in line with predictable patterns of community assemblage development, before reducing sharply immediately prior to drying. Energy availability increased with an increasing hydroperiod and there was a strong correlation (ρ = 0.669, P = 0.0001) between energy availability and fatty acid concentration, which was in turn related to patterns of taxon occurrence. Conclusions and implications. Hydroperiod exerts a strong influence on aquatic invertebrate community trophic dynamics and energy provision. Planned flows should support maturation and stabilisation of the invertebrate community to optimise energy provision to consumers.
