The experience of competition stress and emotions in cricket

The purpose of the study was to conduct an in-depth examination of the stress and emotion process experienced by three sub-elite level male cricketers over a series of five competitive performances. Using reflective diaries and follow up semi-structured interviews, the findings highlighted the impact of appraisal, coping, and emotion on performance, with perceptions of control and self-confidence emerging as variables that can influence the emotive and behavioral outcomes of a stressful transaction. Post-performance, guided athlete reflection was advanced as a valuable tool in the production and application of idiographic coping behaviors that could enhance perceptions of control and self-confidence and influence stress and emotion processes

Transitions at the end of life for older adults - patient, carer and professional perspectives

BackgroundThe end of life may be a time of high service utilisation for older adults. Transitions between care settings occur frequently, but may produce little improvement in symptom control or quality of life for patients. Ensuring that patients experience co-ordinated care, and moves occur because of individual needs rather than system imperatives, is crucial to patients’ well-being and to containing health-care costs.ObjectiveThe aim of this study was to understand the experiences, influences and consequences of transitions between settings for older adults at the end of life. Three conditions were the focus of study, chosen to represent differing disease trajectories.SettingEngland.ParticipantsThirty patients aged over 75 years, in their last year of life, diagnosed with heart failure, lung cancer and stroke; 118 caregivers of decedents aged 66–98 years, who had died with heart failure, lung cancer, stroke, chronic obstructive pulmonary disease or selected other cancers; and 43 providers and commissioners of services in primary care, hospital, hospice, social care and ambulance services.Design and methodsThis was a mixed-methods study, composed of four parts: (1) in-depth interviews with older adults; (2) qualitative interviews and structured questionnaire with bereaved carers of older adult decedents; (3) telephone interviews with care commissioners and providers using case scenarios derived from the interviews with carers; and (4) analysis of linked Hospital Episode Statistics (HES) and mortality data relating to hospital admissions for heart failure and lung cancer in England 2001–10.ResultsTransitions between care settings in the last year of life were a common component of end-of-life care across all the data sets that made up this study, and many moves were made shortly before death. Patients’ and carers’ experiences of transitions were of a disjointed system in which organisational processes were prioritised over individual needs. In many cases, the family carer was the co-ordinator and provider of care at home, excluded from participation in institutional care but lacking the information and support to extend their role with confidence. The general practitioner (GP) was a valued, central figure in end-of-life care across settings, though other disciplines were critical of GPs’ expertise and adherence to guidelines. Out-of-hours services and care homes were identified by many as contributors to unnecessary transitions. Good relationships and communication between professionals in different settings and sectors was recognised by families as one of the most important influences on transitions but this was rarely acknowledged by staff.ConclusionsDevelopment of a shared understanding of professional and carer roles in end-of-life transitions may be one of the most effective ways of improving patients’ experiences. Patients and carers manage many aspects of end-of-life care for themselves. Identifying ways to extend their skills and strengthen their voices, particularly in hospital settings, would be welcomed and may reduce unnecessary end-of-life transitions. Why the experiences of carers appear to have changed little, despite the implementation of a range of relevant policies, is an important question that has not been answered. Recommendations for future research include the relationship between policy interventions and the experiences of end-of-life carers; identification of ways to harmonise understanding of the carers’ role and strengthen their voice, particularly in hospital settings; identification of ways to reduce the influence of interprofessional tensions in end-of-life care; and development of interventions to enhance patients’ experiences across transitions.FundingThe National Institute for Health Research Health Services and Delivery Research programme

Association between Chronic Arsenic Exposure and Nutritional Status among the Women of Child Bearing Age: A Case-Control Study in Bangladesh

The role of nutritional factors in arsenic metabolism and toxicity is yet to be fully elucidated. A low protein diet results in decreased excretion of DMA and increased tissue retention of arsenic in experimental studies. Malnourished women carry a higher risk of adverse pregnancy outcomes. Chronic exposure to high arsenic (>50 μg/L) through drinking water also increases the risk of adverse pregnancy outcomes. The synergistic effects (if any) of malnutrition and chronic arsenic exposure may worsen the adverse pregnancy outcomes. This population based case control study reports the association between chronic arsenic exposure and nutritional status among the rural women in Bangladesh. 348 cases (BMI < 18.5) and 360 controls (BMI 18.5–24.99) were recruited from a baseline survey conducted among 2,341 women. An excess risk for malnutrition was observed among the participants chronically exposed to higher concentrations of arsenic in drinking water after adjusting for potential confounders such as participant’s age, religion, education, monthly household income and history of oral contraceptive pills. Women exposed to arsenic >50 μg/L were at 1.9 times (Odds Ratio = 1.9, 95% CI = 1.1–3.6) increased risk of malnutrition compared to unexposed. The findings of this study suggest that chronic arsenic exposure is likely to contribute to poor nutritional status among women of 20–45 years

A Judd illusion in far-aiming: evidence of a contribution to action by vision for perception

The present study addresses the role of vision for perception in determining the location of a target in far-aiming. Participants (N = 12) slid a disk toward a distant target embedded in illusory Judd figures. Additionally, in a perception task, participants indicated when a moving pointer reached the midpoint of the Judd figures. The number of hits, the number of misses to the left and to the right of the target, the sliding error (in mm) and perceptual judgment error (in mm) served as dependent variables. Results showed an illusory bias in sliding, the magnitude of which was comparable to the bias in the perception of target location. The determination of target location in far-aiming is thus based on relative metrics. We argue that vision for perception sets the boundary constraints for action and that within these constraints vision for action autonomously controls movement execution, but alternative accounts are discussed as well

A stochastic evolutionary model generating a mixture of exponential distributions

Recent interest in human dynamics has stimulated the investigation of the stochastic processes that explain human behaviour in various contexts, such as mobile phone networks and social media. In this paper, we extend the stochastic urn-based model proposed in \cite{FENN15} so that it can generate mixture models, in particular, a mixture of exponential distributions. The model is designed to capture the dynamics of survival analysis, traditionally employed in clinical trials, reliability analysis in engineering, and more recently in the analysis of large data sets recording human dynamics. The mixture modelling approach, which is relatively simple and well understood, is very effective in capturing heterogeneity in data. We provide empirical evidence for the validity of the model, using a data set of popular search engine queries collected over a period of 114 months. We show that the survival function of these queries is closely matched by the exponential mixture solution for our model
