[pt] A importância do sal em diversas atividades humanas tem acompanhado as fases principais da civilização. Aplicações estratégicas e inovadoras envolvendo rochas salinas são planejadas até os dias atuais, tais como barreiras geológicas para abandono de poços e cavernas de estocagem para novas fontes de energia ou descarbonização. Esta tese foca no comportamento geomecânico do sal com atenção especial à fluência, dilatância, efeitos térmicos e seus impactos no comportamento hidráulico. Modelos deram suporte ao desenvolvimento de metodologias para avaliação de condições de integridade e estanqueidade de projetos estratégicos no contexto de energia. Eles incluem o abandono de poços do pré-sal, cavernas de sal e sal como rocha capeadora de reservatórios carbonáticos. Simulações numéricas avançadas utilizando o framework GeMA investigaram cenários representativos de cada projeto. Para tanto, modelos constitutivos de fluência, condições de contorno customizadas e variáveis de saída específicas foram implementados. Dentre os modelos de fluência, o EDMT foi desenvolvido no contexto desta pesquisa de doutorado, com foco no sal brasileiro. Os estudos de caso conduziram a observações importantes. Um poço do pré-sal pode fechar completamente por fluência após a remoção do revestimento. A redução da pressão e o aquecimento do poço aceleraram seu fechamento de modo significativo. No cenário mais crítico, a permeabilidade final foi ligeiramente superior a 100 vezes o valor inicial. Uma caverna de sal pode suportar mecanicamente ciclos de pressão causados por um esquema contingencial de fornecimento de hidrocarbonetos, embora uma permeabilidade final de 6,5 vezes o valor inicial tenha sido observada. Na geomecânica de reservatórios, a contribuição da fluência da rocha capeadora na subsidência é pequena e irreversível mesmo que a pressão do reservatório seja recuperada. As mudanças na permeabilidade foram sutis apesar da contribuição da fluência do sal e da variação de pressão do reservatório. A revisão da literatura, os modelos de fluência, as metodologias de análise, as funcionalidades incorporadas ao framework e as discussões motivadas pelos estudos de caso representam o valor agregado da tese para a comunidade científica e para a indústria no que tange ao aproveitamento estratégico de rochas salinas. / [en] The importance of salt in many human activities has accompanied the main phases of civilization. Strategic and innovative applications in salt rocks are planned until the present day, such as geological barriers for well abandonment and storage caverns for new energy sources or decarbonization. This thesis focuses on the geomechanical behavior of salt with special regards to creep, dilation, thermal effects and their impact on the hydraulic behavior. Models have supported the development of methodologies to assess integrity and tightness conditions of strategic projects in the context of energy. These include Pre-salt well abandonment, salt caverns and salt as caprock of carbonate reservoirs. Advanced numerical simulations using the framework GeMA have investigated representative scenarios of each project. To this end, creep constitutive models, customized boundary conditions and specific output variables have been implemented. Among the creep models, the EDMT has been developed in the context of this doctoral research, focusing on Brazilian salt. The case studies have led to important findings. A Pre-salt well can close completely by creep after casing removal. Pressure reduction and well heating have accelerated closure significantly. In the most critical scenario, the final permeability was slightly higher than 100 times the initial value. A salt cavern can mechanically support pressure cycles caused by a contingency hydrocarbon supply scheme; however, a final permeability of 6.5 times the initial value has been noticed. In reservoir geomechanics, the caprock creep contribution in the subsidence is small and irreversible even if the reservoir pressure is recovered. Permeability changes have been subtle despite the creep contribution and the reservoir pressure variation. The literature review, the creep models, the analysis methodologies, the capabilities incorporated into the framework and the discussions motivated by the case studies represent the added value of the thesis to the scientific community and industry regarding the strategic use of salt rocks.

The human trait of entitlement, although currently very topical, has only recently come under serious scrutiny by behavioural psychologists (Campbell, Bonacci, Shelton, Exline & Bushman 2004:30). This study examines the modifying effects of these psychological elements on the spiritual aspects of disease and healing. Other modifiers are the personal spiritual beliefs or dogmas of the clergy within the paradigm of a particular denomination, and the beliefs and expectations of the adherents. Two Christian denominations were chosen for the study: The Methodist Church of Southern Africa, in particular the home church of the writer, The Bedfordview Methodist Church, and Afmin, an organisation that trains and equips students, mainly African, for Christian ministry. Structured face to face interviews were conducted with pastors and church leaders, interviews with medical professionals were conducted and a wide ranging review of relevant literature undertaken. It was found that while the trait of entitlement was a constant in human nature, there were modifying factors. These included the personal beliefs of pastors and youth leaders, often founded on personal experience instead of denominational dogma. The influence of Pentecostal / Charismatic teaching was very evident. It was also found that the church, in a drive to become increasingly relevant to current norms and social trends, tended to have a rather confused understanding of biblical healing and the role of God in disease and suffering. While the inevitability of death, suffering and disease cannot be denied, the role of the church is complex and controversial. Unrealistic expectations, based on teaching that encourages a sense of entitlement can lead to great challenges regarding faith in both the clergy and adherents. / Christian Spirituality, Church History & Missiology / D.

As a point of departure in this inherently interdisciplinary endeavour, the concept "Holistic Multidisciplinary Management" ("HMM") is introduced a.s a macrocosmic adaption of principles of project management. In line with HMM, a number of submissions regarding terminology and definitions in the interdisciplinary context of medicine (and particularly clinical psychiatry) and law, are made, and the foundations of medical malpractice are examined. Building on the various foundations laid, specific types of conduct that can constitute clinical-psychiatric malpractice, are addressed. A common theme that emerges in the various contexts covered, is that the psychiatrist must negotiate various proverbial tightropes, involving inter alia tensions between restraint and freedom, excessive and insufficient medication, becoming too involved and not being involved enough with clients, as well as client confidentiality and the duty to warn third parties. It is concluded that law and medicine. must work harmoniously together to establish appropriate balance. This can be achieved only if mutual understanding and integrated functioning are promoted and translated into practice. / Law / LL.M.

L’objectif de cette thèse est de jeter un éclairage sur ce qui influence une personne, ayant peur d’être abandonnée, à s’automutiler. Les modèles psychologiques des relations d’objet et de l’attachement ont montré empiriquement que la peur de l’abandon, via les concepts de l’anxiété d’attachement et de la dépendance, est associée à l’automutilation. Cependant, la nature de cette relation n’a jamais été approfondie. Après avoir défini et mis en contexte la notion d’automutilation, une explication théorique est proposée à l’aide des approches des relations d’objet, de l’attachement et de l’évitement expérientiel des fonctions de l’automutilation, afin de mieux comprendre ce qui influencerait une personne dépendante à s’automutiler. La présente thèse suggère que les individus dépendants et ayant peur d’être abandonnés s’automutileraient afin de gérer leurs émotions négatives liées à la perception d’un abandon, d’une séparation ou d’un rejet. Cette influence de l’automutilation se ferait, théoriquement, à travers des fonctions de régulation intrapersonnelle et interpersonnelle, telles que la régulation affective, l’autopunition et l’influence interpersonnelle, mais également par une fonction d’évitement de l’autonomie. Ces fonctions permettraient de préserver les représentations internes d’une relation de dépendance et ainsi réduire les sentiments subjectifs de l’abandon. Pour appuyer empiriquement ces propositions, 58 participants consultant en clinique externe de psychologie ont, entre autres, complété le Questionnaire des expériences dépressives (DEQ), l’Inventaire d’énoncés sur l’automutilation (ISAS) et l’Entrevue diagnostique révisée pour les troubles limites de la personnalité (DIB-R). Les résultats montrent qu’une dépendance, de type anaclitique, et la fréquence de l’automutilation sont associées et que leur relation peut s’expliquer par les effets médiateurs des difficultés sur les plans affectifs et interpersonnels. En outre, la dépendance anaclitique apparaît être liée spécifiquement à différentes fonctions de l’automutilation, soit symboliser la détresse interne, l’antidissociation, l’influence interpersonnelle ainsi que l’évitement de l’autonomie. Ces résultats suggèrent que la dépendance anaclitique favorise l’expérience de difficultés affectives et interpersonnelles qui augmentent la fréquence de l’automutilation. En outre, ils suggèrent que l’automutilation, associée à ce type de dépendance, servirait à réguler des états affectifs internes, influencer l’environnement interpersonnel et éviter l’autonomie. Quant à elles, la régulation affective et l’autopunition sont présentes chez une majorité des personnes qui s’automutilent, sans égard à leur niveau de dépendance. Ainsi, si ces fonctions sont bien liées théoriquement à la dépendance derrière l’automutilation de certains individus, les analyses rappellent qu’elles contribuent également à l’automutilation chez des personnes n’ayant pas de crainte particulière de l’abandon. / The objective of this thesis is to shed light on what may lead a dependent person who fears abandonment to engage in self-injury. Psychological models of object relations and attachment have shown that self-injury is empirically associated with fear of abandonment via dependency and attachment anxiety. However, the nature of this relationship has yet to be thoroughly explained. Having defined and contextualised self-injury, a theoretical explanation is proposed through object relations, attachment and experiential avoidance functions of self-injury, all with the goal of better understanding what can influence a dependent individual to self-injure. This thesis suggests that individuals who are dependent and afraid of being abandoned might use self-injury to regulate negative emotions associated with their perception of abandonment, separation or rejection. Theoretically, this influence of self-injury could occur through intrapersonal and interpersonal functions, such as affect regulation, self-punishment and interpersonal influence, as well as autonomy avoidance. These functions might serve to protect internal representations of dependence and thus, reduce subjective feelings of abandonment. To test these theoretical proposals, 58 outpatient participants completed, among other measures, the Depressive Experiences Questionnaire (DEQ), the Inventory of Statements About Self-Injury (ISAS) and the Revised Diagnostic Interview for Borderlines (DIB-R). Results showed a relationship between anaclitic neediness and self-injury frequency, which was explained by mediator effects of both affective and interpersonal problems. Furthermore, this type of dependency was found to be specifically associated with marking distress, anti-dissociation, interpersonal influence and autonomy avoidance functions of self-injury. These findings suggest that anaclitic neediness favours the experience of affective and interpersonal difficulties, which in turn increase the frequency of self-injury. Results also suggested that self-injury associated with this type of dependency might serve to regulate internal affective states, to influence the interpersonal environment and to avoid autonomy. Affect regulation and self-punishment functions were endorsed by the majority of individuals who self-injured, regardless of their level of dependence. While these two functions are associated in theory to dependency issues that underpin self-injury for some individuals, analyses indicated that these functions also contribute to self-injury behaviour in people who do not fear abandonment specifically.

À l’heure du recyclage et du tri, les déchetteries, outils de leur mise en œuvre, sont investies par nombre d’acteurs en quête d’objets à récupérer. Cette recherche, sollicitée par une collectivité territoriale considérant qu’une gestion optimisée des déchets implique la prise en compte de facteurs humains, s’inscrit dans le champ de la demande sociale. L’exploration anthropologique de l’univers des déchets permet de compléter les analyses techniques et scientifiques plus anciennes. Ce travail rend compte de la nécessité d’appréhender par une démarche ethnopragmatique les discours sur les pratiques instituées à la déchetterie et celles qui s’y sont spontanément greffées, les pratiques informelles. Abordant les enjeux de légitimité et ontologiques qui ont prévalu à la mise en concurrence de pratiques vouées à un même objectif, celui de donner une seconde vie aux déchets, cette recherche repose sur un examen attentif de l’ordinaire d’une déchetterie et sur une étude du langage écrit ou oral des acteurs concernés. Elle se focalise aussi sur le sens donné, dans l’ordinaire des acteurs mais dans un contexte plus large de crise environnementale et de critique de la société de consommation, à l’acte de jeter et à celui de réhabiliter. Elle expérimente tant dans l’investigation que dans la manière d’en rendre compte, la mise en présence d’expériences de terrains d’enquête différenciés. Elle propose ainsi une mise en abyme des cadres de définition et de pensée circonscrits par le terrain d’enquête initial. Elle approfondit les connaissances sur les comportements individuels, les jeux d’acteurs en lien avec les déchets. Elle affine la compréhension des organisations publiques et privées, de leurs stratégies, de processus de décision, de la capacité de changement en matière de politique déchet. / At the time of recycling and sorting , waste sorting , tools implementation , are invested by many actors in search of items to collect . This research, requested by a local authority whereas optimized waste management involves consideration of human factors, is in the field of social demand. The anthropological exploration of the universe of waste can complete the technical and scientific older analyzes . This work reflects the need to understand the process by ethnopragmatique discourse practices established for disposal and those that are spontaneously grafted informal practices . Addressing issues of legitimacy and ontological that prevailed in the competition practice dedicated to the same goal , that of giving a second life to waste , this research is based on a careful examination of the ordinary and dumped on a study of written or spoken language stakeholders. It also focuses on the meaning given in the ordinary players, but in a broader context of environmental crisis and critique of consumer society, the act of throwing and than rehabilitate . She experimented both in the investigation in the way of realizing it, the bringing together experiences of differentiated land survey . It proposes a formal definition abyss frames and thought circumscribed by the initial field survey. It extends the knowledge on individual behavior , games players in connection with the waste. It refines the understanding of public and private organizations, their strategies, decision-making, the ability to change in waste policy.

Politische und sozioökonomische Rahmenbedingungen haben entscheidenden Einfluss auf Landnutzungswandel; die relative Bedeutung dieser Faktoren untereinander ist jedoch oftmals unklar. Ziel dieser Arbeit ist es, durch die Untersuchung der Auswirkungen der politischen und sozioökonomischen Transformation auf Landnutzungswandel in Osteuropa zu einem besseren Verständnis solcher übergreifenden Einflussfaktoren beizutragen. Am Beispiel des Dreiländerecks Polen-Slowakei-Ukraine in den Karpaten wurden hierzu grenzüberschreitende Landschaftsvergleiche durchgeführt, da solche Vergleiche die Entkopplung der Faktoren allgemeiner Landnutzungstrends von Faktoren länderspezifischer Veränderungen ermöglichen. Darüber hinaus sind die Auswirkungen postsozialistischen Landschaftswandels auf die Karpaten, einem Gebiet mit einzigartigem ökologischen Wert, bisher weitestgehend unerforscht. Mit Hilfe von Landsat TM/ETM+ Satellitendaten aus dem Jahr 2000 wurden rezente Landschaftsunterschiede zwischen Ländern quantifiziert. Auf der Basis von Bildern von 1986-2000 wurde anschliessend überprüft, ob Länderunterschiede auf sozialistischen oder post-sozialistischen Landschaftswandel zurückführbar sind. Die Ergebnisse dieser Analysen zeigten weit verbreiteten Landnutzungswandel nach 1989 als Folge von sich verschlechternden wirtschaftlichen Bedingungen, geschwächten Institutionen und gesellschaftlichem Wandel. Die Länder unterschieden sich jedoch auch deutlich hinsichtlich Forstveränderungen, Brachfallung und Parzellierung von Ackerland. Diese Unterschiede lassen sich durch verschiedene Besitzverhältnisse, Bewirtschaftungsformen und Landreformen erklären. Während sich Polen und die Slowakei landschaftlich seit 1989 annähern, entfernt sich die Ukraine zunehmend. Diese Arbeit unterstreicht die Bedeutung ökonomischer und institutioneller Veränderungen für Landschaftswandel und zeigt, wie unterschiedliche Besitzstrukturen und Landreformen Landschaftswandel beeinflussen. / Broad-scale political and socio-economic conditions are powerful determinants of land use change. Yet, their relative importance is unclear. The main goal of this thesis was to increase the understanding of such broad-scale drivers of land use change by studying how Eastern Europe’s landscapes were affected by the political and socio-economic transition after the fall of the Iron Curtain in 1989. The border triangle of Poland, Slovakia, and Ukraine in the Carpathians was selected as a study area, because cross-border comparisons of land use change allow for decoupling overall trends in the transition period from country specific changes. Moreover, the Carpathians are of exceptional ecological value, but little is known about land use effects on these ecosystems after 1989. Post-socialist land use change was quantified based on Landsat TM/ETM+ images by (1) comparing contemporary (year 2000) landscapes among countries, and (2) using images from 1986 to 2000 to investigate whether differences originated from socialist or post-socialist land use change. Results indicated that forest change, farmland abandonment, and farmland parcelization were widespread in the transition period, likely due to worsening economic conditions, weakened institutions, and societal change. However, land use trends also differed strongly among the three countries due to dissimilar land ownership patterns, land management practices, and land reforms. Poland and Slovakia converged in the transition period in terms of land cover, while Ukraine clearly diverged. This thesis provided compelling evidence of the importance of economic and institutional change for land use change and underpinned the pivotal role of ownership patterns and land management policies. These factors were important to understand land use change in Eastern Europe, and they are likely equally important elsewhere.

Contexte. Après des siècles de diminution, la surface forestière de la plupart des pays développés augmente, un phénomène appelé « transition forestière ». Le stock de bois sur pied présente une augmentation plus rapide mais son évolution, associée à des problématiques actuelles majeures, reste négligée. Il est indispensable de caractériser et comprendre ces évolutions, d’en connaître les causes sous-jacentes, et de les reconstituer sur le long terme afin de pouvoir situer les ressources forestières dans une trajectoire d’ensemble et anticiper leur dynamique future. Cette thèse est consacrée aux forêts françaises métropolitaines et repose principalement sur les données de l’IFN. Objectifs. (1) Analyser les changements de surfaces, de stock et de densité de stock et leurs hétérogénéités spatiales et temporelles, sur 40 ans (1975 – 2015) en fonction de facteurs présumés structurer ces évolutions (géographie, propriété et composition). L’existence de changements de vitesse d’expansion a été recherchée. Le lien entre les changements de stock et des propriétés de la forêt (stock et densité de stock initiaux, augmentation récente de surface) ont été analysés. (2) Analyser les mécanismes des changements de stock et décomposer l’expansion selon des ensembles forestiers homogènes du point de vue de leur dynamique. L’analyse se fonde sur une estimation des flux de stock : croissance, recrutement, mortalité et prélèvement. (3) Situer l’expansion actuelle du stock dans une dynamique séculaire. Les stocks de 1892, 1908 et 1929 (associés aux surfaces de statistiques anciennes) ont été estimés par une approche d’imputation conditionnelle de la densité. Un modèle synthétique de densification du stock des forêts a été testé afin d’étudier à quelles conditions sur cette densification il est possible de retracer la chronologie présumée du stock. Résultats. (1) Sur 40 ans, l’expansion en stock a été trois fois plus rapide que celle des surfaces, soulignant l’intensité de la densification des forêts, et ne présente aucun signe de saturation. Les forêts privées, et principalement les forêts feuillues, présentent les expansions de stock et de densité de stock les plus marquées, suggérant le rôle important de l’expansion naturelle et de l’abandon de terres agricoles. Les modèles statistiques révèlent l’effet positif du stock initial et des variations passées de surface sur l’expansion. (2) L’analyse des mécanismes d’expansion a mis en évidence le moindre niveau des prélèvements relativement à la croissance des forêts, et la contribution des forêts jeunes au développement des ressources. Quatre ensembles forestiers synthétiques de dynamiques distinctes et principalement composés de stocks en forêt privée expliquant l’expansion du stock sont identifiés. (3) La reconstitution du stock depuis 1850 suggère une faible densité de stock au début de la période (25 m3/ha) et une augmentation de stock de presque +300% entre 1892 et 2010, soulignant l’importance de cette expansion. Un modèle convexe a été nécessaire pour représenter la densification des forêts, attestant d’une inertie importante à la reconstitution des ressources, interprétée relativement à la baisse progressive des prélèvements ou à une reconstitution progressive de fertilité. Les analyses suggèrent enfin une évolution différenciée dans le temps du modèle de densification pour les forêts provenant de plantations. Conclusion. Ces travaux ont permis de montrer l’importance de l’expansion en stock et la nécessité de contextualiser cette expansion. Cette expansion ancienne ne montre pour l’instant aucune saturation et constitue un stock de carbone croissant qui ne devrait pas diminuer dans les prochaines décennies à conditions contextuelles identiques. L’analyse causale révèle qu’une part importante de l’expansion du stock ne constitue pas une ressource immédiatement disponible. Les futures politiques d’intensification des prélèvements doivent donc être circonstanciées et échelonnées dans le temps / Context. After centuries of decrease, the forest area of most developed countries increase, a phenomenon termed “forest transition”. While current increase in growing stock (GS) is greater than that in area, it remains far less studied. These changes are linked to major current issues. It is essential to assess these changes, to decipher their underlying causes, and to quantify them over the longer term in order to locate current forest resources on a broad trajectory and to anticipate their future dynamics. This thesis is dedicated to French metropolitan forests, which exhibit the most intensive changes in the growing stock in Europe, and relies on data from the French NFI program. Objectives. (1) Analyse forest areal, GS and GS density (GSD) changes and their spatio-temporal variations over 40 years (1975-2015). They were related to factors hypothesized to feature forest changes (geographical contexts, ownership and species composition). We screened for changes in the rate of expansion. The relationships between GS changes and some forest attributes (initial GS and GSD, recent forest area increase) were investigated. (2) Uncover the processes of GS changes and to split the GS expansion magnitude across dynamically-homogeneous forest ensembles. The study was based on GS flux estimation (growth, ingrowth, mortality and harvest). (3) Locate the actual GS expansion in a secular perspective. This analysis consisted in reconstructing the GS chronology since 1850. Levels of GS in 1892, 1908 and 1929 (associated to area of ancient statistics) were estimated using a conditional imputation approach for GSD estimation. Then, a holistic growing stock densification model was implemented to inquire the conditions required on densification patterns and magnitude to simulate the reconstituted GS chronology. Results. (1) Over 40 years, GS increases were three times faster than the areal ones, underlining the intensity of forest densification. No sign of saturation was found. Private forests, and mainly broadleaved ones, presented the greatest GS and GSD increases, suggesting the essential role of natural expansion and agricultural land abandonment. Regression models revealed the positive effect of initial GS and of recent areal increases on GS expansion. (2) The analysis of GS expansion processes evidenced the low level of harvests in comparison to forest growth, and the contribution of recent forests to wood resource development. It led to identify 4 synthetic forest ensembles contributing to the expansion and of distinct dynamics, mainly composed of private forests. (3) GS suggested a very low mean GSD at the beginning of the period (25 m3/ha) and a GS increase by almost +300% between 1892 and 2010, underlying the importance of this expansion. A convex growth model was required to simulate historical forest densification, attesting of a significant inertia in wood resource reconstitution after the forest transition, interpreted based on a gradual decrease in harvest rates for which indices were collected, or to a gradual recovery of site fertility. The analysis also suggested a distinct kinetics for GS densification in plantation forests. Conclusions. These researches reveal the magnitude of GS expansion and the importance of its analysis across forest contexts. This ancient expansion does not present any current sign of saturation and constitute a persistent carbon sink which should not decrease in the next decades assuming similar contextual conditions. According to the process analysis of GS expansion, a significant fraction of the GS increases does not constitute readily available additional wood resources. Thus, future harvest intensification policies must be contextualized and evolving in time
