Implementing skill acquisition research in high performance sport: Reflecting on the importance of autonomy-support for successful collaboration

Perceptual-cognitive-motor skills, such as visual anticipation, are pivotal for superior performance in sport. However, there are only a limited number of skill acquisition specialists working with coaches to develop these skills in athletes. The purpose of this paper is to present a brief reflection on the use of psychological strategies to create an autonomy-supportive environment to embed a skill acquisition research project in high-performance sport. The research project was conducted with the Australian national field hockey high-performance unit and investigated individual differences in expert goalkeepers’ visual anticipation. The paper first discusses the role of a skill acquisition specialist, how they collaborate with coaches and athletes, and barriers to collaboration. The paper then outlines how psychological strategies can be used to create an autonomy-supportive environment to build a relationship and establish a research collaboration with a team. Further, the paper discusses the importance of continually involving coaches and athletes in the research process to facilitate their engagement and self-determined motivation to complete the project. By applying psychological strategies to create an autonomy-supportive environment, sports scientists may have greater success in overcoming the many barriers to conduct research in an elite sport setting, with the outcomes highly valuable for athlete development

Acute Reperfusion Therapy in ST-elevation Myocardial Infarction from 1994-2003

Background—Appropriate utilization of acute reperfusion therapy is not a national performance measure for ST-elevation myocardial infarction at this time, and the extent of its contemporary use among ideal patients is unknown. Methods—From the National Registry of Myocardial Infarction, we identified 238,291 patients enrolled from June 1994 to May 2003 who were ideally suited for acute reperfusion therapy with fibrinolytic therapy or primary percutaneous coronary intervention. We determined rates of not receiving therapy across 3 time periods (June 1994–May 1997, June 1997–May 2000, June 2000– May 2003) and evaluated factors associated with underutilization. Results—The proportion of ideal patients not receiving acute reperfusion therapy decreased by one-half throughout the past decade (time period 1: 20.6%; time period 2: 11.4%; time period 3: 11.6%; P\u3c0.001). Utilization remained significantly lower in key subgroups in the most recent time period: those without chest pain (OR, 0.29; 95% CI, 0.27–0.32); those presenting 6 to 12 hours after symptom onset (OR, 0.57; 95% CI, 0.52–0.61); those 75 years or older (OR, 0.63 compared with patients \u3c55 years old; 95% CI, 0.58–0.68); women (OR, 0.88; 95% CI, 0.84–0.93); and non-whites (OR, 0.90; 95% CI, 0.83–0.97). Conclusions—Utilization of acute reperfusion therapy in ideal patients has improved over the last decade, but more than 10% remain untreated. Measuring and improving its use in this cohort represents an important opportunity to improve care

Large-scale structure in the Lyman-alpha forest II: analysis of a group of ten QSOs

The spatial distribution of Ly-alpha forest absorption systems towards ten QSOs has been analysed to search for large-scale structure over the redshift range 2.2 < z < 3.4. The QSOs form a closely spaced group on the sky and are concentrated within a 1 deg^2 field. We have employed a technique based on the first and second moments of the transmission probability density function which is capable of identifying and assessing the significance of regions of over- or underdense Ly-alpha absorption. We find evidence for large-scale structure in the distribution of Ly-alpha forest absorption at the > 99 per cent confidence level. In individual spectra we find overdense Ly-alpha absorption on scales of up to 1200 km s^-1. There is also strong evidence for correlated absorption across line of sight pairs separated by < 3 h^-1 proper Mpc (q_0 = 0.5). For larger separations the cross-correlation signal becomes progressively less significant.Comment: 15 pages, LaTeX, 6 Postscript figures, accepted for publication in MNRA

Sympatric seals, satellite tracking and protected areas : habitat-based distribution estimates for conservation and management

Analysis was funded by the UK Government Department for Business, Energy and Industrial Strategy (BEIS; OESEA-16-76/OESEA-17-78) with support from the Natural Environment Research Council (NERC; INSITE Phase II NE/T010614/1 EcoSTAR), EU INTERREG (MarPAMM), and the Scottish Government (MMSS/002/15).

Like many predator taxa, pinnipeds face an increasingly complex array of natural and anthropogenic threats. Understanding the relationship between at-sea processes and trends in abundance at land-based monitoring sites requires robust estimates of at-sea distribution, often on multi-region scales. Such an understanding is critical for effective conservation management, but estimates are often limited in spatial extent by spatial coverage of animal-borne tracking data. Grey (Halichoerus grypus) and harbour seals (Phoca vitulina) are sympatric predators in North Atlantic shelf seas. The United Kingdom (UK) and Ireland represents an important population centre for both species, and Special Areas of Conservation (SACs) are designated for their monitoring and protection. Here we use an extensive high-resolution GPS tracking dataset, unprecedented in both size (114 grey and 239 harbour seals) and spatial coverage, to model habitat preference and generate at-sea distribution estimates for the entire UK and Ireland populations of both species. We found regional differences in environmental drivers of distribution for both species which likely relate to regional variation in diet and population trends. Moreover, we provide SAC-specific estimates of at-sea distribution for use in marine spatial planning, demonstrating that hotspots of at-sea density in UK and Ireland-wide maps cannot always be apportioned to the nearest SAC. We show that for grey seals, colonial capital breeders, there is a mismatch between SACs (where impacts are likely to be detected) and areas where impacts are most likely to occur (at sea). We highlight an urgent need for further research to elucidate the links between at-sea distribution during the foraging season and population trends observed in SACs. More generally, we highlight that the potential for such a disconnect needs to be considered when designating and managing protected sites, particularly for species that aggregate to breed and exhibit partial migration (e.g. grey seals), or spatial variation in migration strategies. We demonstrate the use of strategic tracking efforts to predict distribution across multiple regions, but caution that such efforts should be mindful of the potential for differences in species-environment relationships despite similar accessible habitats.Publisher PDFPeer reviewe

Amenability of groups and GG-sets

This text surveys classical and recent results in the field of amenability of groups, from a combinatorial standpoint. It has served as the support of courses at the University of G\"ottingen and the \'Ecole Normale Sup\'erieure. The goals of the text are (1) to be as self-contained as possible, so as to serve as a good introduction for newcomers to the field; (2) to stress the use of combinatorial tools, in collaboration with functional analysis, probability etc., with discrete groups in focus; (3) to consider from the beginning the more general notion of amenable actions; (4) to describe recent classes of examples, and in particular groups acting on Cantor sets and topological full groups

On the syneresis of an OPV functionalised dipeptide hydrogel

We describe a new dipeptide hydrogel based on an oligophenylene vinylene core. After gelation, the initial network evolves, expelling solvent and resulting in syneresis. We describe this process and the effects in the bulk properties of the material
