Transpersoners upplevelse av psykoterapi : Alliansskapnde och brott i den psykoterapeutiska situationen / Transgender clients´ experience in psychotherapy : Alliance and ruptures in psychotherapy

Kerosuo, Maya January 2016 (has links)
Denna kvalitativa studie undersökte fem transpersoners upplevelser av psykoterapi i förhållande till det faktum att de var transpersoner. Syftet var att genom en tematisk analys identifiera teman som antingen kan vara alliansskapande eller leda till brott i den terapeutiska relationen. Fem teman utkristalliserades ur materialet. De var 1. Normkritisk utgångspunkt och queerförståelse hos terapeuten 2. För lite fokus på och förminskande av transidentitetens betydelse 3. Överfokusering på transidentitetens betydelse 4. Upplevelsen att behöva utbilda sin terapeut eller inte 5. Förståelse hur måendet hos transpersoner är kopplat till samhällets syn på normbrytande personer. Studien syftade också till att undersöka vad dessa specifika upplevelser riskerade att leda till i den terapeutiska relationen. Det visade sig att dessa ofta från psykoterapeutens sida oavsiktliga handlingar ledde till minskat förtroende från klientens sida. Detta visar på vikten att som psykoterapeut känna till de vanligaste alliansbrott som kan uppstå med transpersoner, för att förbättra den psykoterapeutiska kvalitén.

Characterising and predicting fracture patterns in a sandstone fold-and-thrust belt

Watkins, Hannah E. January 2015 (has links)
Fracture distribution in a fold and thrust belt is commonly thought to vary depending on structural position, strain, lithology and mechanical stratigraphy. The distribution, geometry, orientation, intensity, connectivity and fill of fractures in a reservoir are all important influences on fractured reservoir quality. The presence of fractures is particularly beneficial in reservoirs that contain little matrix porosity or permeability, for example tight sandstones. In these examples fractures provide essential secondary porosity and permeability that enhance reservoir production. To predict how reservoir quality may fluctuate spatially, it is important to understand how fracture attributes may vary, and what controls them. This research aims to investigate the influence of structural position on fracture attribute variations. Detailed fracture data collection is undertaken on folded sandstone outcrops. 2D forward modelling and 3D model restorations are used to predict strain distribution in the fold-and-thrust belt. Relationships between fracture attributes and predicted strain are determined. Discrete Fracture Network (DFN) modelling is then undertaken to predict fracture attribute variations. DFN modelling results are compared with field fracture data to determine how well fractured reservoir quality can be predicted. Field data suggests strain is a major controlling factor on fracture formation. Fractures become more organised and predictable as strain increases. For example in high strain forelimb regions, fracture intensity and connectivity are high, and fracture orientations are consistent. In lower strain regions, fracture attributes are much more variable and unpredictable. Fracture variations often do not correspond to strain fluctuations, and correlations can be seen between fracture intensity and lithology. Reservoir quality is likely to be much more variable in low strain regions than high strain regions. DFN modelling is also challenging because fracture attribute variations in low strain regions do not correspond to strain, and therefore cannot be predicted.

No. of bitstreams: 0 / A utilização de materiais compósitos poliméricos em elementos estruturais requer o conhecimento do comportamento durante a vida em serviço. A garantia da integridade destes elementos estruturais de compósitos demanda um estudo do comportamento dependente do tempo, por causa da sua resposta viscoelástica e das inúmeras possibilidades de configurações de fabricação. No presente estudo, foram realizados ensaios de fluência e ruptura por fluência em tração em compósitos unidirecionais fabricados com resina epoxídica e fibra de carbono de alta resistência, com os ângulo das fibras a 60º e 90º em relação à direção do carregamento, nas temperaturas de 25 e 70 ºC. A caracterização viscoelástica do compósito foi realizada por meio das curvas de fluência a vários níveis de carregamento constante em períodos de 1000 h, obtenção do envelope de ruptura por fluência pelas curvas de ruptura por fluência, a determinação da transição do comportamento linear para não linear pelos gráficos isócronos e ainda a comparação das curvas de flexibilidade à fluência com um modelo de predição de comportamento viscoelástico fundamentado na equação de Schapery. Pelos ensaios foi constatada uma modificação no comportamento do material, com relação à resistência, rigidez e deformação, demonstrando que estas propriedades foram afetadas pelo tempo e nível de tensão, especialmente em temperatura de trabalho acima da ambiente. O modelo de predição foi capaz de representar o comportamento à fluência, entretanto deve ser considerada a determinação dos termos das equações, além da variação destes com a tensão aplicada e o tempo decorrido de ensaio. / Dissertacao (Mestrado) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

Konsten att identifiera och reparera alliansbrott i kognitiv beteendeterapi : - Om modet att ta ansvar som psykoterapeut

Eberger, Sara, Helsing, Robert January 2016 (has links)
Studiens syfte var att undersöka leg. psykoterapeuters uppfattningar om och erfarenheter av att identifiera och reparera rupturer i den terapeutiska relationen (alliansen) i kognitiv beteendeterapi (KBT). Datainsamlingen bestod av narrativa intervjuer. Den kvalitativa metoden fenomenologisk hermeneutik (Lindseth & Norberg, 2004), där intresset riktas mot den levda erfarenheten, användes vid analys och tolkning av texten. Resultatet visade att de terapeutiska färdigheterna medveten närvaro och metakommunikation används för att identifiera, förebygga och reparera rupturer i alliansen. Slutsatsen är att psykoterapeuternas berättelser bär på den dolda innebörden att alla slags terapeutiska interventioner i KBT samtidigt utgör relationella handlingar, och att ett språk för detsamma är önskvärt. Meningsfullhet och yrkesstolthet kan dessutom tillägnas, om uppmärksamheten vänds från misslyckanden till mod att ta ansvar för det terapeutiska förloppet och relationen. / The aim of the study was to investigate psychotherapists perceptions about and experiences of identifying ruptures in the therapeutic alliance in cognitive behavioural therapy (CBT). The data collection consisted of narrative interviews. The qualitative method, a phenomenological hermeneutical method for researching lived experience (Lindseth & Norberg, 2004), was used in the analysis and interpretation of the texts. The result showed that the therapeutic skills awareness and metacommunication was used to identify, prevent and resolve ruptures in the alliance. The conclusion is that psychotherapists stories carries a hidden meaning of any therapeutic interventions in CBT at the same time constitutes relational actions, and a language for the same is desirable. Meaningfulness and professional pride can also be adopted, by shifting attention from failures, into courage to take responsibility for the therapeutic process and the relationship.
