Spatial scaling properties of coral reef benthic communities

The spatial structure of ecological communities on tropical coral reefs across seascapes and geographies have historically been poorly understood. Here we addressed this for the first time using spatially expansive and thematically resolved benthic community data collected around five uninhabited central Pacific oceanic islands, spanning 6° latitude and 17° longitude. Using towed-diver digital image surveys over ~140 linear km of shallow (8–20 m depth) tropical reef, we highlight the autocorrelated nature of coral reef seascapes. Benthic functional groups and hard coral morphologies displayed significant spatial clustering (positive autocorrelation) up to kilometre-scales around all islands, in some instances dominating entire sections of coastline. The scale and strength of these autocorrelation patterns showed differences across geographies, but patterns were more similar between islands in closer proximity and of a similar size. For example, crustose coralline algae (CCA) were clustered up to scales of 0.3 km at neighbouring Howland and Baker Islands and macroalgae were spatially clustered at scales up to ~3 km at both neighbouring Kingman Reef and Palmyra Atoll. Of all the functional groups, macroalgae had the highest levels of spatial clustering across geographies at the finest resolution of our data (100 m). There were several cases where the upper scale at which benthic community members showed evidence of spatial clustering correlated highly with the upper scales at which concurrent gradients in physical environmental drivers were spatially clustered. These correlations were stronger for surface wave energy than subsurface temperature (regardless of benthic group) and turf algae and CCA had the closest alignments in scale with wave energy across functional groups and geographies. Our findings suggest such physical drivers not only limit or promote the abundance of various benthic competitors on coral reefs, but also play a key role in governing their spatial scaling properties across seascapes

Grim tales: Meetings, matterings and moments of silencing and frustration in everyday academic life

Universities are dominated by marketisation, individualisation and competition, forces inimical to individual flourishing and collaborative endeavours. This article presents four stories from a collective biography workshop in which a group of women academics explored everyday moments in their university lives. The stories are grim tales of damage, silencing, frustration and cynicism, whose affects continue to reverberate. The article makes two contributions to higher education research. One, its focus on mundane moments offers insights into embodied dynamics of gender, power and affect within the neoliberal university. Two, it demonstrates how collective biography as a feminist methodology can mobilise increased awareness of shared experiences and, thereby, enable participants to work together to recognise and contest the affective grimness of their workplaces

Graduate attributes: implications for higher education practice and policy: Introduction

The higher education landscape is shifting under neo-liberal forces that are increasingly aligning the goals of business, government and education. This shift is engendering debate around the world about the role of higher education institutions in producing employable graduates to feed national prosperity in the emerging knowledge economy. As this evolution continues, we need to consider how we enhance generic graduate capabilities as well as the disciplinary expertise of our undergraduate students. Our graduates should possess the knowledge, skills and values to enable them to cope with dynamic employment opportunities, but they must also understand, through the benefits and constraints of their disciplinary perspectives, who they are and how they might contribute positively to the heterogeneity they will encounter in their local, regional and global communities

“It’s my dream to work with Olympic athletes”: Neophyte sport psychologists’ expectations and initial experiences regarding service delivery

We examined trainee practitioners' initial experiences of applied sport psychology practice. Semi-structured interviews (4) were conducted over 6 months with 7 full-time MSc students before, during, and after the applied sport psychology module, when they were working with clients. Participants also kept reflective diaries over an 8-week period whilst working with clients. Findings included: (a) motivations and expectations of an ASP practice career, (b) perceptions of service delivery, (c) emotional demands, and (d) pivotal experiences. Findings extend previous literature on the initial stages of practitioner development, providing micro-level detail on aspects of the intense development process during this pivotal perio

‘Working on a rocky shore’: Micro-moments of positive affect in academic work

Neoliberal ideologies, marketization and performative regimes ssociated with recent reforms in universities have exerted considerable pressure on academic working conditions and subjects in recent years. While analysing these pressures is important, it is also productive to consider the ways in which academics engage in moments of resistance by mobilising resources beyond those of critique. This paper therefore focuses on joy and positive affect in the everyday moments of academic life. It utilises the feminist methodology of collective biography to explore ways of making the restricted spaces of our working day more expansive and finding within them unexpected openings for joy. Our analysis of the stories included in this paper traces the mercurial and ambiguous affective atmospheres of academic work. We suggest that joy is founded upon connections with others, that it arises in different academic spaces and that it can lead to revised knowing of ourselves. We argue that the glimpses of joy evident in this paper provoke affective attunement within the everyday, sensitizing us to other fragments of joy and providing strategies to strengthen that resistance

The Primary PE and School Sport Premium

Central to London’s successful bid to host the 2012 Olympic and Paralympic Games, was the Government’s commitment to improve competitive sport and the sporting habits of young people (Ofsted, 2014). On the 12th March 2013, the then Prime Minister, David Cameron, announced that Primary Schools in England would receive funding worth £150 million per year to create a sustainable infrastructure for long-lasting change and improve the provision of physical education (PE) and sport across all state maintained primary schools. Speaking at the time, he said: ‘We can create a culture in our schools that encourages all children to be active and enjoy sport.’ He added: ‘The Olympic and Paralympic Games marked an incredible year for this country and I will always be proud that we showed the world what Britain can do. I want to ensure the Games count for the future too and that means capitalising on the inspiration young people took from what they saw during those summer months.’: https://www.bbc.co.uk/sport/21808982 Six years on, and with a total investment now of over £1.2 billion, the Primary PE and Sport Premium (here onwards referred to as the PESS Premium) has been a defining feature of the London 2012 legacy. Invariably funding streams at this level do not last forever or in the same format, which raises significant questions about what impact the funding has had on young people since 2013. We believe that a significant investment from Government merits debate and accountability at the highest possible level and that it should acknowledge where the opportunities and shortcomings of such a policy have left us. During the years of austerity, mounting concerns have arisen over the present and long term state of children’s health and the need for the debate to be heard is now imperative. To date there has been little critical appraisal of the PESS Premium funding. This report aims to begin a necessary process and in doing so, brings together evidence from across the sector to consider the future of the PESS Premium post 2018. During the course of the report, we outline and underpin the holistic value and importance of PE for every child. We examine the historic status and funding of PE and Sport and the nature and increasing diversity of the workforce. How has the PESS Premium funding impacted the way in which the subject is regarded and the ability of those tasked with delivering it to discharge their responsibilities? We have uncovered an abiding uncertainty about the nature of the PESS Premium itself; the ways in which it may be spent and its effect on an increasing divide between PE specialists, generalists and externally contracted coaches. Will its legacy be to have established a secure foundation for lifelong physical activity, sport and education – or is it, in effect, another temporarily seductive mirage, leaving PE precisely where it has become accustomed to be; regularly sidelined, delivered largely by those who are not qualified teachers and perpetuating the status quo for the children who already belong to groups that are perceived to be at a disadvantage? The PESS Premium funding is a significant sum and these questions deserve answers. This report is therefore our contribution to an essential debate, containing practical suggestions that we hope will be of use to policy makers. We invite all who care about the physical and mental health and emotional wellbeing of children to join the discussion

Migration patterns of Greenland halibut in the North Atlantic revealed by a compiled mark-recapture dataset

Marine fisheries are often allocated to stocks that reflect pragmatic considerations and may not represent the species’ spatial population structure, increasing the risk of mismanagement and unsustainable harvesting. Here we compile mark–recapture data collected across the North Atlantic to gain insight into the spatial population structure of Greenland halibut (Reinhardtius hippoglossoides), an issue that has been unresolved for decades. The dataset contains 168130 fish tagged from 1952 to 2021, with 5466 (3.3%) recaptured individuals. Our results indicate that fish tagged at <50 cm body length migrate at higher rates, suggesting that mark–recapture studies on adult individuals underestimate population-level migration rates. We find evidence for migrations across management units in the North Atlantic indicating two regional offshore populations: one in the Northeast Atlantic, where the West Nordic and Northeast Arctic stocks, currently managed separately, likely belong to a single population that spans from the Kara Sea to Southeast Greenland; and one in the Northwest Atlantic where migration was observed between the Newfoundland and Labrador stock and the Northwest Arctic stock in Davis Strait and Baffin Bay. Our findings indicate complex population structure with implications for international and domestic fisheries management of this long-lived species.publishedVersio

An Intraocular Pressure Polygenic Risk Score Stratifies Multiple Primary Open-Angle Glaucoma Parameters Including Treatment Intensity

Purpose: To examine the combined effects of common genetic variants associated with intraocular pressure (IOP) on primary open-angle glaucoma (POAG) phenotype using a polygenic risk score (PRS) stratification. Design: Cross-sectional study. Participants: For the primary analysis, we examined the glaucoma phenotype of 2154 POAG patients enrolled in the Australian and New Zealand Registry of Advanced Glaucoma, including patients recruited from the United Kingdom. For replication, we examined an independent cohort of 624 early POAG patients. Methods Using IOP genome-wide association study summary statistics, we developed a PRS derived solely from IOP-associated variants and stratified POAG patients into 3 risk tiers. The lowest and highest quintiles of the score were set as the low- and high-risk groups, respectively, and the other quintiles were set as the intermediate risk group. Main Outcome Measures: Clinical glaucoma phenotype including maximum recorded IOP, age at diagnosis, number of family members affected by glaucoma, cup-to-disc ratio, visual field mean deviation, and treatment intensity. Results: A dose–response relationship was found between the IOP PRS and the maximum recorded IOP, with the high genetic risk group having a higher maximum IOP by 1.7 mmHg (standard deviation [SD], 0.62 mmHg) than the low genetic risk group (P = 0.006). Compared with the low genetic risk group, the high genetic risk group had a younger age of diagnosis by 3.7 years (SD, 1.0 years; P < 0.001), more family members affected by 0.46 members (SD, 0.11 members; P < 0.001), and higher rates of incisional surgery (odds ratio, 1.5; 95% confidence interval, 1.1–2.0; P = 0.007). No statistically significant difference was found in mean deviation. We further replicated the maximum IOP, number of family members affected by glaucoma, and treatment intensity (number of medications) results in the early POAG cohort (P ≤ 0.01). Conclusions: The IOP PRS was correlated positively with maximum IOP, disease severity, need for surgery, and number of affected family members. Genes acting via IOP-mediated pathways, when considered in aggregate, have clinically important and reproducible implications for glaucoma patients and their close family members
