Technical performance variations in elite Olympic recurve archers
No full textThis study analysed the shot cycle of elite Olympic recurve archers in major tournaments to understand how they exploit movement variability to achieve the same performance outcomes. Participants were 30 top World-ranked archers (15 men and 15 women) who competed in different World Cup series in 2023. A video notational analysis system was designed, based on the shot cycle (stance, bow raise, loading, full draw, anchor, release and follow-through), to assess technical variability in the elite archers. For each archer, 18 shots were selected from analysis of performance in individual or team competitions. Results showed that the elite archers used different forms in each phase of the shot cycle. Findings also revealed that there were two styles of Olympic recurve archery in the sample of elite performers; some displayed a common style and some a more complex style. The two styles were mainly different in movement complexity when raising the bow, loading and bow arm follow-through. In conclusion, the designed notational analysis system in recurve archery can be used by coaches and performance analysts for the skill adaptation of young archers in their development pathway. The existing technical variability in the elite archers can justify our definition of the ideal/optimal performance in this sport and direct towards skill adaptations based on individual, environmental and task constraints

"We're one small piece of the puzzle": Evaluating the impact of short-term funding for tier two weight management services
No full textOverweight and obesity are a global health epidemic and many attempts have been made to address the rising prevalence. In March 2021 the UK government announced £100 million of additional funding for weight management provisions. Of this, £30.5 million was split across local authorities in England to support the expansion of tier two behavioural weight management services for adults. The present work aimed to explore how this funding was used within the Yorkshire and Humber region to consolidate learning, collate best practice, and provide recommendations for future funding use. One-hour semi-structured interviews were conducted with 10 weight management service commissioners representing 9 of the 15 local authorities in the region. Interviews were recorded, transcribed and analysed using an established health inequality framework. From this, recommendations were co-developed with the commissioner group to establish best practice for future funding use. Commissioners recognised that targeted weight management services were only one small piece of the puzzle for effectively managing obesity. Therefore, recommendations include targeting underserved communities, focussing on early prevention, addressing weight management in a whole systems context, and embracing innovative and holistic approaches to weight management. Current short-term funding and restrictive commissioning processes of tier two services prevents sustainable and innovative weight management practice which is detrimental to patients, falls short of addressing health inequalities and negatively impacts staff health and wellbeing
Increasing the reach of the Skills Centre: Implementation and evaluation of interventions expanding the reach to underserved students of the Sheffield Hallam University Skills Centre
No full textPatterns of low engagement from underserved students are well documented in Higher Education institutions. This research project aimed to highlight potential barriers to learning to underserved student groups and implement practical changes to practice in order to address these barriers and create a more inclusive environment in which all students feel a sense of belonging
Data for "Ice Sheet Speed-dating: Using expert judgement to identify "good" simulations of the Last Glacial Maximum North American Ice Sheets"
No full textData for Short Communication "Ice Sheet Speed-dating: Using expert judgement to identify "good" simulations of the Last Glacial Maximum North American Ice Sheets" in review at Quaternary Science Reviews.
Abstract: After generating a large ensemble of palaeo ice sheet model runs, it is common to either rank the simulations, or classify each simulation as an acceptable match to observations or not. Both tasks require implicit human judgement, usually left to the discretion of the research authors. For instance, even numerical comparisons to reconstructions require human input on values for match thresholds and allowances for model-mismatch. We embrace the subjectivity of human judgement and calibrate an ice-sheet model by explicitly asking experts to identify simulations that are good enough. Expert judgement is made based on a set of features of the model output that is of interest (for example, margin shapes and regional ice volumes); where possible we also record such knowledge. By seeking the input of many experts, we obtain a community consensus that can be used to develop guidance to determine the quality of future simulations. This short communication describes our exercise in seeking expert classifications of simulations of the Last Glacial Maximum (LGM) North American Ice Sheets, discusses the lessons learnt, and suggests future analysis of the responses

Synergistic homovalent and heterovalent substitution effects on piezoelectric and relaxor behavior in lead-free BaTiO3 ceramics
No full textThis study investigates lead-free BaTiO3 (BT) perovskite ceramics, unraveling the synergistic effects arising from simultaneous homovalent (Zr) and heterovalent (Nb) substitution. Focusing on piezoelectric, ferroelectric, and relaxor behaviors, this research employs a comprehensive suite of analyses, including temperature-dependent
dielectric measurements, polarization-electric field hysteresis loops, and bipolar strain measurements. Significantly, our study unveils that the simultaneous substitution of Zr and Nb in the BT lattice induces roomtemperature relaxor behavior at relatively low concentrations (5 % Zr and 3 % Nb), yielding higher permittivity and larger maximum polarization compared to single element (Zr or Nb) substituted BT relaxors. Bipolar strain measurements showcase substantial large-signal d33* values (~250 pm/V) across a broad temperature range (–50 ◦C to 30 ◦C) for BT ceramics with simultaneous 5 % Zr and 2 % Nb substitution. This research advances understanding of homovalent and heterovalent substitution in BT ceramics and opens avenues for tailoring properties to suit specific applications
DiverReef: The global repository of divers' and snorkelers' behavior during tourism activities and their interactions with reef environments over 20 years
No full textThe DiverReef database provides the first public dataset on the underwater behavior of recreational divers and snorkellers in shallow reef environments (< 25 m depth) globally and their interactions with the reef seascape and/or reef benthic sessile organisms. The dataset comprises 19 years of data (2004-2023) by observing the behavior of 2312 recreational divers and snorkelers in 9 countries at 19 diving destinations and 176 diving sites. The data were collected through on-site observation of divers' behavior during tourism activities and their physical interactions with the reef structure and/or benthic reef sessile organisms. Observers discretely followed divers and recorded their behavior and interactions with the reef over set time periods. Interactions were described as "contact" and "damage", the latter refers to when physical damage to a benthic organism or the reef structure was observed. Besides behavior, observers also recorded data on the type of diving activity (scuba or snorkeling), profiles of the divers (gender and experience), use of cameras by the divers, visibility, type of reef formation and marine protection status of the dive site.
