A phenomenological interpretation of the parent-child relationship in elite youth football

Youth sport parenting research, in psychology, has methodologically prioritised individual level analysis of the behaviours, perceptions or needs of parents and young athletes. While this has contributed greatly to understanding the role of parents in sport, children’s parenting preferences and the challenges of parenting in this unique setting, an exploration of parenting in youth sport from a dyadic, inter-individual perspective has received far less attention. Accordingly, the purpose of this research was to explore parent’s and children’s experience of their interaction and relationship, in the context of elite youth football. Eight parent-player dyads, recruited from English professional football club youth academies, participated in phenomenological interviews. A two-stage analysis process was performed to explore individual parent and player experiences and examine how accounts related dyadically. Findings present a detailed description and interpretation of the parent-player relationship; as one constituted by relations with other family members, an embodied sense of closeness, the temporal significance of football transitions, and gender relations. This research advocates the need for a view of parenting in youth sport that accounts for how interaction is experienced by both parents and children and highlights the importance of conceptualising parenting as an embodied, temporal process, constituted through interaction and the social context

Assessing heat pumps as flexible load

In a future power system featuring significant renewable generation, the ability to manipulate domestic demand through the flexible operation of heat-led technologies such as heat pumps and micro-combined heat and power could be a critical factor in providing a secure and stable supply of electrical energy. Using a simulation-based approach, this study examined the linkage between the thermal characteristics of buildings and the scope for flexibility in the operating times of air source heat pumps. This was assessed against the resulting impact on the end-user’s comfort and convenience. A detached dwelling and flat were modelled in detail along with their heating system in order to determine the temporal shift achievable in the heat pump operating times for present-day and future dwellings. The simulation results indicated that the scope for shifting heat pump operating times in the existing building stock was limited, with time shifts of only 1–2 h achieved before there was a serious impact on the comfort of the occupant. However, if insulation levels were dramatically improved and substantial levels of thermal buffering were added into the heating system, sizable time shifts of up to 6 h were achievable without a significant impact on either space or hot water temperatures

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

Players’ Understanding of Talent Identification in Early Specialisation Youth Football

Despite research illustrating the socially constructed and subjective nature of talent identification in football, little research has explored how players make sense of ‘being talented’ and how this shapes their identity experiences. Five football academy players aged 11 years participated in five focus group interviews. Thematic and interactional qualitative analyses were performed to examine the content and function of participants’ talk. Findings described how players constructed being scouted as authentically choosing, or being chosen by, a club, which worked to protect or enhance participants’ talented identities and self-worth. Talent was regarded as dynamic, but players’ perceived expectation to continuously improve implied a potentially problematic view of development as linear. Evidence of early socialisation into the academy culture indicated that while effort was seen as virtuous, it was used to judge performance in comparison to peers, suggesting that effort had become a rhetorical device that reflected conformity, rather than player motivation

The contribution of political skill to the implementation of health services change: a systematic review and narrative synthesis

BACKGROUND: The implementation of strategic health system change is often complicated by informal ‘politics’ in healthcare organisations. Leadership development programmes increasingly call for the development and use of ‘political skill’ as a means for understanding and managing the politics of healthcare organisations. The primary purpose of this review is to determine how political skill contributes to the implementation of health services change, within and across organisations. The secondary purpose is to demonstrate the conceptual variations within the literature. METHODS: The article is based upon a narrative synthesis that included quantitative, qualitative and mixed methods research papers, review articles and professional commentaries that deployed the concept of political skill (or associated terms) to describe and analyse the implementation of change in healthcare services. RESULTS: Sixty-two papers were included for review drawn from over four decades of empirically and conceptually diverse research. The literature is comprised of four distinct literatures with a lack of conceptual coherence. Within and across these domains, political skill is described as influencing health services change through five dimensions of leadership: personal performance; contextual awareness; inter-personal influence; stakeholder engagement, networks and alliances; and influence on policy processes. CONCLUSION: There is a growing body of evidence showing how political skill can contribute to the implementation of health services change, but the evidence on explanatory processes is weak. Moreover, the conceptualisation of political skill is variable making comparative analysis difficult, with research often favouring individual-level psychological and behavioural properties over more social or group processes

Mathematical Modeling of Streptococcus pneumoniae Colonization, Invasive Infection and Treatment

Streptococcus pneumoniae (Sp) is a commensal bacterium that normally resides on the upper airway epithelium without causing infection. However, factors such as co-infection with influenza virus can impair the complex Sp-host interactions and the subsequent development of many life-threatening infectious and inflammatory diseases, including pneumonia, meningitis or even sepsis. With the increased threat of Sp infection due to the emergence of new antibiotic resistant Sp strains, there is an urgent need for better treatment strategies that effectively prevent progression of disease triggered by Sp infection, minimizing the use of antibiotics. The complexity of the host-pathogen interactions has left the full understanding of underlying mechanisms of Sp-triggered pathogenesis as a challenge, despite its critical importance in the identification of effective treatments. To achieve a systems-level and quantitative understanding of the complex and dynamically-changing host-Sp interactions, here we developed a mechanistic mathematical model describing dynamic interplays between Sp, immune cells, and epithelial tissues, where the host-pathogen interactions initiate. The model serves as a mathematical framework that coherently explains various in vitro and in vitro studies, to which the model parameters were fitted. Our model simulations reproduced the robust homeostatic Sp-host interaction, as well as three qualitatively different pathogenic behaviors: immunological scarring, invasive infection and their combination. Parameter sensitivity and bifurcation analyses of the model identified the processes that are responsible for qualitative transitions from healthy to such pathological behaviors. Our model also predicted that the onset of invasive infection occurs within less than 2 days from transient Sp challenges. This prediction provides arguments in favor of the use of vaccinations, since adaptive immune responses cannot be developed de novo in such a short time. We further designed optimal treatment strategies, with minimal strengths and minimal durations of antibiotics, for each of the three pathogenic behaviors distinguished by our model. The proposed mathematical framework will help to design better disease management strategies and new diagnostic markers that can be used to inform the most appropriate patient-specific treatment options

Characterising the phenotypic diversity of Papilio dardanus wing patterns using an extensive museum collection

The history of 20th Century evolutionary biology can be followed through the study of mimetic butterflies. From the initial findings of discontinuous polymorphism through the debates regarding the evolution of mimicry and the step-size of evolutionary change, to the studies on supergene evolution and molecular characterisation of butterfly genomes, mimetic butterflies have been at the heart of evolutionary thought for over 100 years. During this time, few species have received as much attention and in-depth study as Papilio dardanus. To assist all aspects of mimicry research, we present a complete data-derived overview of the extent of polymorphism within this species. Using historical samples permanently held by the NHM London, we document the extent of phenotypic variation and characterise the diversity present in each of the subspecies and how it varies across Africa. We also demonstrate an association between “imperfect” mimetic forms and the transitional race formed in the area where Eastern and Western African populations meet around Lake Victoria. We present a novel portal for access to this collection, www.mimeticbutterflies.org, allowing remote access to this unique repository. It is hoped that this online resource can act as a nucleus for the sharing and dissemination of other collections databases and imagery connected with mimetic butterflies
