The impact of abuse experiences and coping responses on distress and mental health outcomes in sports officials

Sports officials (e.g., referees) experience multiple role-related stressors, including episodes of verbal, physical, and social media abuse. However, the impact of strategies employed to cope with abuse experiences is unknown. The aims of this study were to: (i) explore the prevalence and frequency of abuse experiences over a single season, (ii) determine the impact of abuse and other stressors on sports officials’ mental health, and (iii) understand the mental health impact of strategies utilised by sports officials to cope with abuse experiences. A total of 303 Gaelic games match officials completed an online survey measuring stressors (including abuse experiences), coping strategies, and mental health outcomes. Correlational and path analyses explored relationships between abuse experiences, coping strategies, distress, and subsequent mental health outcomes. In total, 88.11% of officials reported experiences of verbal abuse, 7.59% physical abuse, and 17.16% social media abuse during the previous season. Greater use of both avoidance-cognitive and approach-oriented coping was associated with higher distress and poorer mental health outcomes following verbal abuse. Moreso, greater use of avoidance-cognitive strategies to cope with verbal abuse from players predicted higher distress which, in turn, predicted higher anxiety, higher depression, and lower mental well-being. For social media abuse, self-blame, planning, and behavioural disengagement were associated with poorer mental health. The findings suggest that sports officials employ maladaptive coping for abuse experiences, negatively impacting on mental health outcomes. Developing alternative strategies, such as mastery-oriented coping, may help sports officials to deal with abuse experiences and better protect their mental health

E-tracers:development of a low cost wireless technique for exploring sub-surface hydrological systems

This briefing describes the first deployment of a new electronic tracer (E-tracer) for obtaining along-flowpath measurements in subsurface hydrological systems. These low-cost, wireless sensor platforms were deployed into moulins on the Greenland Ice Sheet. After descending into the moulin, the tracers travelled through the subglacial drainage system before emerging at the glacier portal. They are capable of collecting along-flowpath data from the point of injection until detection. The E-tracers emit a radio frequency signal, which enables sensor identification, location and recovery from the proglacial plain. The second generation of prototype E-tracers recorded water pressure, but the robust sensor design provides a versatile platform for measuring a range of parameters, including temperature and electrical conductivity, in hydrological environments that are challenging to monitor using tethered sensors

Patient-specific cancer genes contribute to recurrently perturbed pathways and establish therapeutic vulnerabilities in esophageal adenocarcinoma

Abstract: The identification of cancer-promoting genetic alterations is challenging particularly in highly unstable and heterogeneous cancers, such as esophageal adenocarcinoma (EAC). Here we describe a machine learning algorithm to identify cancer genes in individual patients considering all types of damaging alterations simultaneously. Analysing 261 EACs from the OCCAMS Consortium, we discover helper genes that, alongside well-known drivers, promote cancer. We confirm the robustness of our approach in 107 additional EACs. Unlike recurrent alterations of known drivers, these cancer helper genes are rare or patient-specific. However, they converge towards perturbations of well-known cancer processes. Recurrence of the same process perturbations, rather than individual genes, divides EACs into six clusters differing in their molecular and clinical features. Experimentally mimicking the alterations of predicted helper genes in cancer and pre-cancer cells validates their contribution to disease progression, while reverting their alterations reveals EAC acquired dependencies that can be exploited in therapy

The impact of injuries study. Multicentre study assessing physical, psychological, social and occupational functioning post injury - a protocol

Background: Large numbers of people are killed or severely injured following injuries each year and these injuries place a large burden on health care resources. The majority of the severely injured are not fully recovered 12-18 months later. Psychological disorders are common post injury and are associated with poorer functional and occupational outcomes. Much of this evidence comes from countries other than the UK, with differing health care and compensation systems. Early interventions can be effective in treating psychological morbidity, hence the scale and nature of the problem and its impact of functioning in the UK must be known before services can be designed to identify and manage psychological morbidity post injury. Methods/Design : A longitudinal multi-centre study of 680 injured patients admitted to hospital in four areas across the UK: Nottingham, Leicester/Loughborough, Bristol and Surrey. A stratified sample of injuries will ensure a range of common and less common injuries will be included. Participants will complete a baseline questionnaire about their injury and pre-injury quality of life, and follow-up questionnaires 1, 2, 4, and 12 months post injury. Measures will include health and social care utilisation, perceptions of recovery, physical, psychological, social and occupational functioning and health-related quality of life. A nested qualitative study will explore the experiences of a sample of participants, their carers and service providers to inform service design. Discussion: This study will quantify physical, psychological, social and occupational functioning and health and social care utilisation following a range of different types of injury and will assess the impact of psychological disorders on function and health service use. The findings will be used to guide the development of interventions to maximise recovery post injury

Mental health in sports match officials

The importance of positive mental health amongst athletes and sports coaches has received much attention in recent years. However, there has been limited consideration given to the mental health of sports match officials. This chapter will outline the numerous and unique stressors experienced by match officials within their role, and the impact of these stressors on subsequent mental health outcomes. This chapter will also highlight the lack of evidence-informed interventions to support the mental health of match officials. Consequently, we will provide an insight into a recent mental health-focused intervention within association football in England. We will provide a critical reflection on the intervention and present key learnings and implications to inform future mental health support for sports match officials

A novel experimental apparatus for investigating bubbly flows in a slot geometry

Bubbly flows occur in a wide variety of industrial and environmental settings. While there is a broad literature that describes bubbly flow behavior in pipes and channels, flow in a high aspect ratio slot has received little attention. We describe the design and construction of a new experimental apparatus to investigate the processes associated with bubbly flows in a slot geometry. The apparatus is designed to perform scaled analog experiments to investigate the flow of bubbly magma through the sub-volcanic plumbing system, but it is sufficiently flexible to address many other flow scenarios. The main bubble column, which can be inclined up to 30° from the vertical, comprises a glass-walled slot 3 m wide and 2 m tall, with 3 cm gap width. A modular and flexible gas injection system allows the number, spacing, and diameter of the gas emission points to be varied, as well as gas injection flux, and a pumped recirculation system allows the concurrent liquid flow rate to be controlled and varied. A dedicated data acquisition system synchronizes high-speed videography with temperature and pressure data from different points in the apparatus. Preliminary data are presented to demonstrate the operation of the apparatus and to illustrate the types of fluid dynamic information that can be captured
