<p> Although the occupational callings literature has largely focused on positive outcomes of living a calling, there are some emerging findings that suggest that callings may have a “negative” side as well. Drawing upon past studies within the callings literature, as well as upon theoretical perspectives such as self-regulation theory, identity theory, and the Effort-Recovery model, I tested a theoretical model to examine psychological detachment as a mechanism that accounts for the relationship between living a calling (also referred to as one’s calling intensity) and two well-being outcomes: sleep quality and burnout. Further, I built on previous work in the callings literature by examining the moderating impact of two individual differences (trait mindfulness, perfectionism) on the relationship between calling intensity and psychological detachment. Study hypotheses were tested using a two-wave study design with 358 emergency medical professionals. Results revealed that for called emergency medical professionals, trait mindfulness strengthened the negative relationship between calling intensity and psychological detachment, which had downstream negative effects on sleep quality. In addition, one facet of perfectionism, namely perfectionistic strivings, exacerbated the negative indirect effect of calling intensity on sleep quality via psychological detachment. Ultimately, this study contributed to the occupational callings literature by examining the impact of differential levels of trait mindfulness and perfectionism on employee well-being. Implications for enhancing employee well-being are discussed.</p>

The sensation of detachment and reclusion frequently gives rise to an uncanny and dreamlike space. Enveloped within this dimension, the quirks of memory become a fragile lifeline to bygone, intangible ideas of reality. Fixated on this threshold, my artistic explorations in print, collage, and assemblage navigates these elusive realms, rendering fragmented and distant shapes and figures in stark contrast to elements that evoke an eerie sense of familiarity. In this manner, my work invites viewers to embrace the disconcerting and unsettling aspects of the in-between, all the while establishing an unsettling connection to reality through the lens of nostalgic objects and imagery.

[pt] Esta pesquisa visa refletir sobre a participação do adolescente no processo de desligamento do acolhimento institucional, como um direito à convivência familiar e comunitária. No estudo, considerou-se o sentimento de pertencimento dos adolescentes como fator diferencial para que este processo seja construído e vivido junto com os mesmos. Entendemos que este processo se dá por meio da escuta atenta dos adolescentes, sendo pautado nos princípios dos direitos humanos, nos quais são reconhecidos como pessoas que têm direitos e acesso a estes por meio de sua participação. A análise possibilitou evidenciar o compromisso do labor institucional com o adolescente acolhido, respeitando seu direito de participação no processo de acolhimento, incentivando sua autonomia, bem como seu sentimento de pertencimento, como elementos fundamentais para o desligamento institucional. A pesquisa, de natureza qualitativa, foi realizada na Unidade de Reinserção Social Bangu (URS Bangu). A coleta de dados foi feita por meio de observação participante e registros sistemáticos em diário de campo sobre o cotidiano dos adolescentes na instituição. A pesquisa foi complementada com oficinas e grupos focais, focalizando a participação dos adolescentes no processo de desligamento institucional. Esta dissertação articula um tema de grande importância acadêmica com o debate em políticas públicas, visando contribuir para o aprofundamento do conhecimento sobre o direito à convivência familiar e comunitária e o processo de desligamento de adolescentes em acolhimento institucional. / [en] This research aims to reflect on the participation of the adolescent in the process of detachment of institutional care, as a right to family and community coexistence. In the study, the adolescents sense of belonging was considered as a differential factor for this process to be constructed and lived along with them. We understand that this process occurs through the attentive listening of adolescents, based on the principles of human rights, where they are recognized as persons, who have rights and access to them through their participation. The qualitative research was carried out at the Bangu Social Reinsertion Unit (URS Bangu). The data collection was done through participant observation and systematic records in field diary about the daily life of adolescents in the institution. The research was complemented by workshops and focus groups, focusing on the participation of adolescents in the process of institutional disengagement. The analysis made it possible to highlight the commitment of the institutional work with the adolescents, respecting their right to participate in the reception process, encouraging their autonomy and building a sense of belonging. These are fundamental elements for the process of institutional detachment and for their insertion in the world. This dissertation articulates a topic of great academic importance with the debate in public policies, aiming to contribute to the deepening of the knowledge about the right to family and community coexistence and the process of detachment of adolescents in institutional care.

Mid-Tertiary metamorphic core complexes in the Basin and Range province of the western North American Cordillera are characterized by large-magnitude extensional deformation. Numerous models have been proposed for the kinematic evolution of these metamorphic core complexes. Such models generally invoke footwall isotatic rebound due to tectonic denudation, and the presence of a weak middle crust capable of flow at mid-crustal levels. In popular models of Cordilleran-style metamorphic core-complex development, initial extension occurs along a breakaway fault, which subsequently is deformed into a synform and abandoned in response to isostatic rebound, with new faults breaking forward in the dominant transport direction. In southeast Arizona, the Catalina and Pinaleño Mountains core complexes have been pointed to as type examples of this model. In this study, the “traditional” core-complex model is tested through analysis of field relations and geochronological age constraints, and by interpretation of seismic reflection profiles along a transect incorporating these core complexes. Elements of these linked core-complex systems, from southwest to northeast, include the Tucson Basin, the Santa Catalina-Rincon Mountains, the San Pedro trough, the Galiuro Mountains, the Sulphur Springs Valley, the Pinaleño Mountains, and the Safford Basin. A new digital compilation of geological data, across highly extended terranes, in conjunction with reprocessing and interpretation of a suite of industry 2-D seismic reflection profiles spanning nearly sub-parallel to regional extension, illuminate subsurface structural features related to Cenozoic crustal extension and provide new constraints on evolution of core complexes in southeast Arizona. The main objective is to develop a new kinematic model for mid-Tertiary extension and core complex evolution in southeast Arizona that incorporates new geological and geophysical observations. Geological and seismological data indicate that viable alternative models explain observations at least as well as previous core-complex models. In contrast to the “traditional” model often employed for these structures, our models suggest that the southwest- and northeast-dipping normal-fault systems on the flanks of the Galiuro Mountains extend to mid-crustal depths beneath the San Pedro trough and Sulphur-Springs Valley, respectively. In our interpretations and models, these oppositely vergent fault systems are not the breakaway faults for the Catalina and Pinaleño detachment systems.

Dans les dernières années, les incendies majeurs dans les tunnels ont causé des dommages importants. Dans ces conditions extrêmes (la température dépasse rapidement 1200 °C), l'augmentation de pression dans les pores, la dilatation thermique empêchée, l'incompatibilité de dilatation thermique entre la pâte du ciment et des granulats, la déshydratation ... sont des principaux mécanismes de dégradation qui peuvent être à l'origine de l'écaillage. L'écaillage progressif pendant l'incendie se manifeste par le détachement de la surface du béton par petits morceaux réduisant ainsi la section résistante et pouvant conduire à une rupture prématurée de la structure. Dans cette thèse, un modèle éléments finis THM est enrichi par un modèle d'écaillage progressif en proposant un critère d'écaillage de type détachement-flambement. La partie thermo-hydrique du modèle THM est basée sur l'approche à trois fluides en milieux partiellement saturés. Le comportement mécanique est développé dans le cadre d'une approche thermo-poro-mécanique couplée à l'endommagement et à la plasticité adoucissante. Cette modélisation de l'écaillage conduit à un problème avec frontière et conditions aux limites évolutives. Une stratégie de résolution numérique sans remaillage a été développée pour transférer les conditions aux limites THM simultanément avec l'occurrence de l'écaillage. L'implémentation du modèle dans le code aux éléments finis CESAR-LCPC a permis de procéder à différentes études paramétriques et à des confrontations avec des essais pour évaluer les capacités opérationnelles du modèle à décrire l'occurrence de l'écaillage et identifier les paramètres majeurs qui la contrôlent / In the recent years, there were major tunnels fires which caused fatalities and severe traffic restrictions. In such extreme conditions (temperatures exceeding 1200 °C for considerable time spans), pore pressure build-up, restrained thermal dilatation, cement paste to aggregate incompatibility, dehydration... are some main degradation mechanisms of concrete that may cause its thermal spalling. Progressive concrete spalling occurring during a fire presents as the breakdown of surface layers which flake into small pebble-like pieces. Then, the resistant section of the structure reduces which may lead to its premature failure.In this thesis, a THM finite element model is enriched with a detachment-buckling type criterion for progressive spalling. The thermo-hygral part of the THM model is based on the three fluid approach for partially saturated porous media. The mechanical part is derived within the framework of thermo-poro-mechanics coupled to damage and softening plasticity.The adopted modeling of spalling leads to a problem with evolving boundary and boundary conditions. A suitable numerical solution strategy without remeshing is then developed in order to transfer properly the THM boundary conditions simultaneously with spalling occurrence.The efficiency of the model THM-Spalling is illustrated by some numerical examples and by parametric studies. These studies identify the influence, on spalling, of size variation of spalling flakes, the average spalling velocity and uncertainties on different material parameters. Confrontation with experimental tests shows satisfactory capacity of the THM-Spalling model in reproducing qualitatively the occurrence of spalling

Les conditions pour la fusion DT peuvent-être obtenues dans les tokamaks. Dans ces machines, l'interaction plasma-paroi et l'extraction de puissance sont gérées dans une cavité appelée divertor. Toutefois, les hautes puissances impliquées et les limitations des composants face au plasma (CFP) sont problématiques. Ce domaine fait l'objet de nombreuses recherches dans le contexte de ITER qui doit démontrer 500 MW de puissance fusion durant 400 s. Ces opérations nécessitent sur la réduction des flux de chaleur sur les CFP à un niveau gérable et repose sur le détachement du plasma dans le divertor qui implique la décroissance des flux de particules et de chaleur. Malheureusement, ce processus demeure difficile à modéliser. Le but the ce doctorat est d'utiliser la modélisation d'expériences de JET avec EDGE2D-EIRENE pour faire des progrès dans la compréhension du détachement. Les simulations reproduisent le détachement observé en environnement C comme Be/W. La distribution du rayonnement est reproduite par le code en C mais des écarts subsistent en Be/W. La comparaison entre différents processus de physique atomique montre que les collisions élastiques ion-molécule sont responsables du détachement. Ce processus permet le confinement des neutres dans le divertor ainsi que des pertes de moments significatives à basse température lorsque le plasma est recombinant. La comparaison entre EDGE2D-EIRENE et SOLPS4.3 montre des tendances similaires pour le détachement. Les deux codes suggèrent que tout processus capable d'améliorer le confinement des neutres dans le divertor devrait faciliter la modélisation du détachement. / The conditions required for fusion can be obtained in tokamaks. In most of these machines, the plasma wall-interaction and the exhaust of heating power are handled in a cavity called divertor. However, the high heat flux involved and the limitations of the materials of the plasma facing components (PFC) are problematic. Many researches are done this field in the context of ITER which should demonstrate 500 MW of DT fusion power during ~ 400 s. Such operations could bring the heat flux on the PFC too high to be handled. Its reduction to manageable levels relies on the divertor detachment involving the reduction of the particle and heat fluxes on the PFC. Unfortunately, this phenomenon is still difficult to model. The aim of this PhD is to use the modelling of JET experiments with EDGE2D-EIRENE to make some progress in the understanding of the detachment. The simulations reproduce the observed detachment in C and Be/W environments. The distribution of the radiation is well reproduced by the code for C but with some discrepancies in Be/W. The comparison between different sets of atomic physics processes shows that ion-molecule elastic collisions are responsible for the detachment seen in EDGE2D-EIRENE. This process provides good neutral confinement in the divertor and significant momentum losses at low temperature, when the plasma is recombining. Comparison between EDGE2D-EIRENE and SOLPS4.3 shows similar detachment trends but the importance of the ion-molecule elastic collisions is reduced in SOLPS4.3. Both codes suggest that any process capable of improving the neutral confinement in the divertor should help to improve the modelling of the detachment.

This is the first monograph to be published on the work of the Queen Alexandra's Imperial Military Nursing Service (QAIMNS) in the Great War. The historiography of British military nursing during this period is scant, and research based monograph are negligible. What exists, does not focus specifically on the work of the Queen Alexandra's Imperial Military Nursing Service, (QAIMNS) the Reserve, (QAIMNSR) or the Territorial Force Nursing Service (TFNS) but tends to concentrate on the work of the volunteer, untrained, Voluntary Aid Detachment (VAD) nurses. Unfortunately, this has resulted in factually inaccurate representations of British WW1 nursing. The mass mobilisation of nurses by professional and voluntary nursing services led to rivalry between the different groups and my research addresses the relationship that develop between the trained and volunteer nurses. Also, my research examines the climatic and environmental conditions that impacted upon the effective delivery of nursing and casualty care and the mismanagement of services and supplies by the War Office and the Army Medical Services. Additionally, the political controversies and scandals over inadequate planning for the care, treatment and transportation of mass casualties is addressed. Furthermore, diseases and traumatic injuries sustained by nurses on active service are examined and, shell-shock, hitherto considered a combatants' condition is cited in relation to mental health issues of nurses on active service. Moreover, my research examines the deaths and disability rates within the ranks of nursing services. My research features individual awards for acts of bravery and mentioned in Dispatches. On the Home Front the politics of nursing are addressed. Nurses campaigned for professional recognition and many were supportive of universal suffrage and they argued for both professional and personal liberation. The struggle for professional recognition led to divisions within the civilian nursing leadership because they failed to arrive at a consensus on the content of the Nurse Registration Bill. Also, the supply of nurses for the war effort was consistently problematic and this led the Government to establish the Supply of Nurses Committee. Before it had its first sitting it had already become contentious and controversial. The issues are discussed. Using extensive primary sources, the monograph moves away from the myths, and uncritical and overly romanticised views of WW1 military nursing. It is hoped that by examining the personal, professional and political issues that impacted upon nurses the monograph will make a significant contribution to the historiography of WW1 military nursing and to the history of the Great War more generally.

The purpose of this dissertation is to examine the life of Wordsworth as presented in The Prelude through the approach of Ch¡¦an (Zen) Buddhism. Three other topics will be touched on in addition to an introduction to Ch¡¦an: language, I and nature. Basic notions of Ch¡¦an are introduced to form a basis for the understanding of and interpretation of later chapters. The language of Wordsworth is analyzed to show two key points: the empty essence of language and Wordsworth¡¦s attachment to abstractions. The emptiness of abstractions in this chapter also serves as a basis for the discussions of nature in chapter four. The notion of self in The Prelude is examined in the episodes of Wordsworth¡¦s life to see his attachments and detachments; joy and sadness. Nature is then analyzed and divided into ¡§nature as it is¡¨ and ¡§nature as is meant¡¨ through the examination of The Prelude. The research finds that Wordsworth¡¦s early exposure to nature helps cultivate a much selfless ¡§I,¡¨ which explains his devotion to the French Revolution as he pursues it for the welfare of the public. His experiences of oneness with nature helps him experience rare cases of beauty, sublimity, develop imagination, and are later used as a powerful momentum to fight the conflict and pain in life. Yet as his experiences of one with nature gradually fade away from his memories under the constant conflict of his later grown-up life, he is more and more sucked into the gyration of differentiation. The mistakening of empty abstractions for his life¡¦s ideal gets him into the web of transcendental signifiers without any real solace. Attaching to abstractions only makes him stay away from the real and trap in the world of distinction and illusion. Only when he is back in nature and reality can he regain his pleasantness and joy.
