    This thesis reappraises military morale during the First World War, looking at the relationship between morale and perceptions of crisis. It analyses the resilience of English infantrymen serving on the Western Front during three acute ‘crisis’ periods faced by the British Army in 1914, 1916, and 1917/1918. Through the examination of contemporary sources, it reveals how infantrymen’s long-term experiential perceptions of war and the Western Front functioned to promote resilience. Generally focussing on moments outside of combat, it argues that many combatants perceived the war itself as a prolonged chronic crisis. Adaptations deflected experiences of chronic crisis and soldiers often failed to register acute crisis and did not distinguish these phases as ones of ‘crisis’ at the time. The dissertation draws on untapped archival material, mainly using sources written during or shortly after the events being studied. It investigates the interrelationship between soldiers’ social and physical environment, and their psychological environment. Deploying theory from anthropology, sociology and social psychology, it goes further than previous work in its interdisciplinary scope. The individual chapters reflect the themes that emerged most forcefully from the primary material. The first four describe the ways in which men overcame chronic crisis, while the final chapter analyses the emergence of acute crisis. ‘Attachment’ explores how men familiarised themselves with the physical environment of the Western Front, normalised it and found meaning in it. ‘Exhaustion’ analyses the experience of winter, showing how this subsumed other concerns and changed men’s perspective on war during other seasons of the year. ‘Obligation’ reinterprets the ways in which concepts of duty influenced soldiers’ actions and interpretation of the conflict. ‘Imagination’ develops a fresh perspective on the ways in which men’s perceptions and dreams of England became a coping mechanism and furnished a justification of their suffering. ‘Hope’ argues that visions of peace proved to be sustaining and were inextricably linked to ideas of victory. The thesis offers new insights into the psychology of the soldiers of 1914-18, and the conclusion suggests that human adaptability and the ability to construe events constructively, to have goals and see clear pathways to these goals, helped men to cope with the Great War

    International Journal of Exercise Science 12(4): 324-331, 2019. The purpose of this investigation was to determine the agreement among three bioelectrical impedance analysis devices (BIA) in athletic young adults. Fifty-one participants (26 men and 25 women) were assessed for percent body fat (PBF) using an arm-to-arm bipolar single-frequency device (ABIA), a leg-to-leg single-frequency device (LBIA), and an octopolar multi-frequency BIA device (MFBIA). PBF was measured with the three devices in a randomized, counterbalanced order. Repeated measures ANOVA revealed significant (p \u3c 0.001) differences in PBF estimates among all devices (ABIA = 19.1 ± 7.2%, LBIA = 21.6 ±7.5%, and MFBIA = 22.9 ± 8.8%). Pearson’s Correlations revealed a strong relationship between ABIA and MFBIA in both men (r = 0.948) and women (r = 0.947) and a moderately-strong relationship between LBIA and MFBIA (r = 0.870 and 0.679, respectively). Lin’s concordance coefficient revealed moderately-strong concordance between ABIA and MFBIA in men (ρc= 0.800) and women (ρc= 0.681) and between LBIA and MFBIA (ρc = 0.846 and ρc= 0.651, respectively). These data indicate a strong agreement among all three devices, suggesting that any of them could be used to track changes in PBF over time. However, the significant differences in PBF values among devices imply that best practice for monitoring body composition should be to use one device consistently over time for a reliable assessment

    Introduction: Last year, Chittenden Emergency Food Shelf provided 1,260,517 pounds of food to over 11,000 people each month via groceries, hot meals and home delivery, supplying an average of almost 40% of food for families. CEFS seeks to improve their services and offerings by better understanding the demographics, food preference, and needs of the clients they serve. Our goal was to collect demographic and utilization data to identify areas where CEFS could enhance services and improve client access to healthful food.https://scholarworks.uvm.edu/comphp_gallery/1208/thumbnail.jp

    A time-invariant visco-elastic windkessel model relating blood flow and blood volume

    Get PDF
    The difference between the rate of change of cerebral blood volume (CBV) and cerebral blood flow (CBF) following stimulation is thought to be due to circumferential stress relaxation in veins (Mandeville, J.B., Marota, J.J.A., Ayata, C., Zaharchuk, G., Moskowitz, M.A., Rosen, B.R., Weisskoff, R.M., 1999. Evidence of a cerebrovascular postarteriole windkessel with delayed compliance. J. Cereb. Blood Flow Metab. 19, 679-689). In this paper we explore the visco-elastic properties of blood vessels, and present a dynamic model relating changes in CBF to changes in CBV. We refer to this model as the visco-elastic windkessel (VW) model. A novel feature of this model is that the parameter characterising the pressure-volume relationship of blood vessels is treated as a state variable dependent oil the rate of change of CBV, producing hysteresis in the pressure-volume space during vessel dilation and contraction. The VW model is nonlinear time-invariant, and is able to predict the observed differences between the time series of CBV and that of CBF measurements following changes in neural activity. Like the windkessel model derived by Mandeville, J.B., Marota, J.J.A., Ayata, C., Zaharchuk, G., Moskowitz, M.A., Rosen, B.R., Weisskoff, R.M., 1999. Evidence of a cerebrovascular postarteriole windkessel with delayed compliance. J. Cereb. Blood Flow Metab. 19, 679-689, the VW model is primarily a model of haemodynamic changes in the venous compartment. The VW model is demonstrated to have the following characteristics typical of visco-elastic materials: (1) hysteresis, (2) creep, and (3) stress relaxation, hence it provides a unified model of the visco-elastic properties of the vasculature. The model will not only contribute to the interpretation of the Blood Oxygen Level Dependent (BOLD) signals from functional Magnetic Resonance Imaging (fMRI) experiments, but also find applications in the study and modelling of the brain vasculature and the haemodynamics of circulatory and cardiovascular systems.

    Design for Product Service Supportability (DfPSS) Approach: A State of the Art to Foster Product Service System (PSS) Design

    Get PDF
    Product-Service System lifecycle is characterized by several phases from the initial concept to the final disposal. However, as for conventional products, the profit generation and the market success of PSSs critically depend on the decisions taken during the initial lifecycle stages, when PSSs are conceptualized, designed, developed and engineered. These are hence the phases deserving more attention in order to manage the intrinsic complexity of such systems, taking it in account during the entire PSS life cycle design phase. According to this, one of the main gaps detected in the PSS design process is the lack of methods able to support the early integration of service features during the product design. In this specific context DfX approaches, where X= x-bility stands for enhancing products design considering at the same time service features to be embedded on it (x) according to certain performance measures (-bility), are supposed to significantly contribute. The Serviceability point of view appears to be a critical aspect of the design of product-oriented PSS that has not been improving yet: significant enhancement in this products' characteristic will only occur if some changes will arise in the way they are designed. Indeed companies still need guidelines able to enhance the PSS design process in a more systematic way. On this basis, due to the main gap of integrating service features in the product design process, the paper presents and defines DfX approaches enlightening, among the several target properties they have been called to improve so far, the most suitable DfX streams detected to solve the reported PSS design issue and to define Design for Product Service Supportability (DfPSS)

    Adolescent Propensity to Engage in Health Risky Behaviors: The Role of Individual Resilience

    Get PDF
    In this paper we create indices of resilience to identify adolescents at risk of smoking, drinking alcohol, and using illegal drugs. Using data from the National Longitudinal Study of Adolescent Health, three manifestations of resilience were identified: overall-resilience, self/family-resilience, and self-resilience. Our analysis reveals that the overall-resilient were less likely to engage in risky behaviors. The self/family resilient were more likely to engage in risky behaviors, but consumed less. The self-resilient had reduced risk for smoking and drinking alcohol but elevated risk for using illegal drugs and being in an addictive stage of smoking and drinking, if participating

    Partnership disengagement from primary community care networks (PCCNs): A qualitative study for a national demonstration project

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>The Primary Community Care Network (PCCN) Demonstration Project, launched by the Bureau of National Health Insurance (BNHI) in 2003, is still in progress. Partnership structures in PCCNs represent both contractual clinic-to-clinic and clinic-to-hospital member relationships of organizational aspects. The partnership structures are the formal relationships between individuals and the total network. Their organizational design aims to ensure effective communication, coordination, and integration across the total network. Previous studies have focused largely on how contractual integration among the partnerships works and on its effects. Few studies, however, have tried to understand partnership disengagement in PCCNs. This study explores why some partnerships in PCCNs disengage.</p> <p>Methods</p> <p>This study used a qualitative methodology with semi-structured questions for in-depth interviews. The semi-structured questions were pre-designed to explore the factors driving partnership disengagement. Thirty-seven clinic members who had withdrawn from their PCCNs were identified from the 2003-2005 Taiwan Primary Community Care Network Lists.</p> <p>Results</p> <p>Organization/participant factors (extra working time spend and facility competency), network factors (partner collaboration), and community factors (health policy design incompatibility, patient-physician relationship, and effectiveness) are reasons for clinic physicians to withdraw or change their partnerships within the PCCNs.</p> <p>Conclusions</p> <p>To strengthen partnership relationships, several suggestions are made, including to establish clinic and hospital member relationships, and to reduce administrative work. In addition, both educating the public about the concept of family doctors and ensuring well-organized national health policies could help health care providers improve the integration processes.</p

    Evolutionary Dynamics of Immune-Related Genes and Pathways in Disease-Vector Mosquitoes

    Get PDF
    Mosquitoes are vectors of parasitic and viral diseases of immense importance for public health. The acquisition of the genome sequence of the yellow fever and Dengue vector, Aedes aegypti (Aa), has enabled a comparative phylogenomic analysis of the insect immune repertoire: in Aa, the malaria vector Anopheles gambiae (Ag), and the fruit fly Drosophila melanogaster (Dm). Analysis of immune signaling pathways and response modules reveals both conservative and rapidly evolving features associated with different functional gene categories and particular aspects of immune reactions. These dynamics reflect in part continuous readjustment between accommodation and rejection of pathogens and suggest how innate immunity may have evolved
