Social comparison in physical education: motives, frames of reference and consequences

Grounded in Festinger s (1954) theory of social comparison processes, this thesis aims to examine three aspects of this theory in the physical education context, where ability is the characteristic under comparison: adolescent motives for comparison; frames of reference; and consequences of comparison. Although there is a growing evidence base investigating social comparison processes in academic subjects, there remains a dearth of knowledge concerning the role that comparison can play in determining outcomes in physical education. Furthermore, there is very little research within psychology in general that examines young peoples motives for and outcomes of comparison. This thesis begins to address this lack of knowledge by providing an in-depth exploration of social comparison processes (Study 1) which is followed by an examination of the role that two frames of reference (the class and a chosen individual) and motives for comparison (evaluation, improvement, enhancement) play in determining: physical self-concept; engagement; disaffection; self-efficacy, positive affect and negative affect (Studies 2-4). Additionally, the moderating role of behavioural regulations, motivational climate and perceived autonomy support are also investigated. Across the four studies, comparative evaluations with the class are influential in determining both positive and negative outcomes whilst the role of individual comparisons varies according to the dependent variable under investigation. Evidence for both the moderating and direct role of motives for comparison is presented as well as support for the moderating role of motivational climate and behavioural regulations. The findings highlight the need to investigate multiple aspects of social comparison processes simultaneously in addition to investigating moderators of comparative evaluations in order that a more comprehensive understanding of social comparison processes is achieved

Methodological pluralism in qualitative research: Reflections on a meta-study

A short report is provided of a meta-study of methodological pluralism in qualitative research; that is, of the use of two or more qualitative methods to analyse the same data set. Ten eligible papers were identified and assessed. Their contents are described with respect to theory, methods and findings, and their possible implications discussed in relation to a series of wider debates in qualitative research more generally

Analytical Pluralism in Qualitative Research: A Meta-Study

Recent interest in analytical pluralism – the application of more than one qualitative analytical method to a single data set – has demonstrated its potential to produce multiple, complex and varied understandings of phenomena. However tensions remain regarding the commensurability of findings produced from diverse theoretical frameworks, the practical application of multiple methods of analysis and the capacity of pluralism to contribute to knowledge in psychology. This study addresses these issues, through a critical interpretation of existing qualitative studies that utilised analytical pluralism. Using a meta-study design, we examined the use of theory, application of methods and production of findings in studies that had adopted qualitative analytical pluralism. Following comprehensive database searches, 10 articles were included in the analysis. Epistemological and ontological considerations, the influence of decisions made in the practical application of pluralism and approaches to interpreting findings produced from multiple analyses are discussed, and implications for future research are considered

A simple, robust flow cytometry-based whole blood assay for investigating sex differential interferon alpha production by plasmacytoid dendritic cells

Central to sex differences observed in outcome from infection and vaccination is the innate immune response, and specifically production of type I interferons by plasmacytoid dendtiric cells (pDCs), the main producers of IFN-α. Evaluation of IFN-α production by pDCs is therefore critical for studies of innate immune function. However, reliable measurement of pDC IFN-α is hampered by reduced cell yields and cytokine production after cryopreservation or after even short delays in stimulating freshly isolated cells. We here describe a simple yet robust method for measuring IFN-α production in pDCs that preserves cell activation and cytokine production through immediate stimulation of whole blood and subsequent maintenance at 37 °C

Urgent care for patients with dementia: a scoping review of associated factors and stakeholder experiences

Objectives People with dementia are more vulnerable to complications in urgent health situations due to older age, increased comorbidity, higher dependency on others and cognitive impairment. This review explored the factors associated with urgent care use in dementia and the experiences of people with dementia, informal carers and professionals.Design Scoping review. The search strategy and data synthesis were informed by people with dementia and carers.Data sources Searches of CINAHL, Embase, Medline, PsycINFO, PubMed were conducted alongside handsearches of relevant journals and the grey literature through 15 January 2019.Eligibility criteria Empirical studies including all research designs, and other published literature exploring factors associated with urgent care use in prehospital and emergency room settings for people with dementia were included. Two authors independently screened studies for inclusion.Data extraction and synthesis Data were extracted using charting techniques and findings were synthesised according to content and themes.Results Of 2967 records identified, 54 studies were included in the review. Specific factors that influenced use of urgent care included: (1) common age-related conditions occurring alongside dementia, (2) dementia as a diagnosis increasing or decreasing urgent care use, (3) informal and professional carers, (4) patient characteristics such as older age or behavioural symptoms and (5) the presence or absence of community support services. Included studies reported three crucial components of urgent care situations: (1) knowledge of the patient and dementia as a condition, (2) inadequate non-emergency health and social care support and (3) informal carer education and stress.Conclusions The scoping review highlighted a wider variety of sometimes competing factors that were associated with urgent care situations. Improved and increased community support for non-urgent situations, such as integrated care, caregiver education and dementia specialists, will both mitigate avoidable urgent care use and improve the experience of those in crisis

Mast Cells and Their Progenitors in Allergic Asthma

Mast cells and their mediators have been implicated in the pathogenesis of asthma and allergy for decades. Allergic asthma is a complex chronic lung disease in which several different immune cells, genetic factors and environmental exposures influence the pathology. Mast cells are key players in the asthmatic response through secretion of a multitude of mediators with pro-inflammatory and airway-constrictive effects. Well-known mast cell mediators, such as histamine and bioactive lipids are responsible for many of the physiological effects observed in the acute phase of allergic reactions. The accumulation of mast cells at particular sites of the allergic lung is likely relevant to the asthma phenotype, severity and progression. Mast cells located in different compartments in the lung and airways have different characteristics and express different mediators. According to in vivo experiments in mice, lung mast cells develop from mast cell progenitors induced by inflammatory stimuli to migrate to the airways. Human mast cell progenitors have been identified in the blood circulation. A high frequency of circulating human mast cell progenitors may reflect ongoing pathological changes in the allergic lung. In allergic asthma, mast cells become activated mainly via IgE-mediated crosslinking of the high affinity receptor for IgE (Fc epsilon RI) with allergens. However, mast cells can also be activated by numerous other stimuli e.g. toll-like receptors and MAS-related G protein-coupled receptor X2. In this review, we summarize research with implications on the role and development of mast cells and their progenitors in allergic asthma and cover selected activation pathways and mast cell mediators that have been implicated in the pathogenesis. The review places an emphasis on describing mechanisms identified using in vivo mouse models and data obtained by analysis of clinical samples
