How therapists understand their experiences of working at a depth of engagement in therapy : an Interpretative Phenomenological Analysis

Eilbeck, Joan January 2017 (has links)
This research provides in depth analysis of how qualified and experienced doctoral therapists and graduates of the professional doctorate counselling programmes, understood and made sense of their experiences in working at a depth of engagement in therapy. A qualitative approach of interpretative phenomenological analysis is the methodology used. This provides rich, detailed analysis of individuals' accounts where idiographic focus and participants' lived experiences remain central. Six Doctoral counselling therapists were individually interviewed via a semi-structured interview schedule. Participants' counselling orientations varied, with most describing themselves as integrative practitioners. Six accounts were examined separately and then analysed. Clusters and themes developed. Themes were also analysed to ascertain convergence and divergence in participants' accounts. Implications are discussed with data rooted in verbatim extracts and embedded within relevant literature. The study presents super-ordinate themes of, 'the indefinable', 'spiritual in nature', 'levels of encounter', 'dissolution of boundaries', 'personally challenging', 'nourishing of the self' and 'professional questioning'. Findings show how participants called upon phenomenological perspectives, epistemological lenses, spiritual and neurobiological discourses and counselling theory, used interchangeably, to try and understand their experiences. The study also points to practitioners crossing interpersonal boundaries, their fear of being judged by the counselling community and their reluctance to take certain aspects of the phenomenon to supervision. The implications of the research highlight whole areas of experiencing that are not being supervised and show challenges on many levels for the counselling community. Such an IPA study also highlights divisions and commonalities in how participants make sense of the phenomenon and a contribution is offered indicating where further research would be helpful. Overall this research study invites a greater awareness and greater openness to understand the ripples and challenges practitioners face from working at a depth of engagement.

Migration DOM-métropole des années 1960 à nos jours : itinéraires d’une minorité française / The routes of a French minority : DOM-mainland migration since the 1960’s

Haddad, Marine 03 December 2018 (has links)
Cette thèse étudie la relation entre les dynamiques migratoires et les trajectoires sociales des migrants nés dans les DOM et installés en France métropolitaine. Ma recherche se focalise sur la démographie des flux migratoires, l’insertion sur le marché du travail, ainsi que le rôle joué par la citoyenneté et les frontières ethno-raciales. J’adopte une approche multi-méthodes. D’une part, je combine des bases de données issues d’enquêtes menées en métropole et dans les DOM, offrant une perspective de long terme sur les flux migratoires et les trajectoires des migrants (Recensements de la Population 1968-1999 ; Enquêtes Emploi 1982-2012 ; Trajectoires et Origines 2008 ; Migration Famille Vieillissement 2012). D’autre part, j’ai mené 40 entretiens semi-directifs avec des ultramarins de la région parisienne, travaillant pour beaucoup dans le secteur public. Mes résultats montrent l’impact des politiques publiques encourageant la migration sur la croissance, la structure et la sélection des flux. En étudiant l’effet croisé des politiques, du contexte économique et des dynamiques familiales, mes analyses montrent comment la mobilité des ultramarins répond à des enjeux économiques, émotionnels et normatifs. La position intermédiaire des migrants des DOM – situés entre la population majoritaire et les immigrés – joue à des niveaux objectifs et subjectifs. Les effets combinés de leur catégorisation raciale en tant que Noirs, des variations liées aux perceptions de leur couleur de peau et de la légitimité conférée par l’ancienneté de leur citoyenneté française façonnent leurs positions socioéconomiques et symboliques dans la stratification sociale française. / This thesis studies the relation between migration dynamics and social paths of migrants born in the French Overseas Departments (DOM) and living in mainland France. My research focuses on the demography of migration flows, labor market outcomes, as well as the role played by citizenship and ethno-racial boundaries. I follow a mixed-methods approach. On the one hand, I combine large datasets from surveys conducted in mainland France and the DOM, providing a long-term assessment of migration flows and migrants’ trajectories (the French Census from 1968 to 1999; the Labor Force Survey from 1982 to 2012; Trajectoires et Origines, 2008; Migration Family Ageing, 2012). On the other hand, I conducted 40 semi-directive interviews with overseas migrants living in the Paris area, focusing mainly on public servants. My results show the impact of public policies promoting migration on flows’ growth, structure, and selection. Looking at the crossed effect of policies, economic context, and family dynamics, my analysis reveals how migrants balance economic, emotional, and normative concerns. The intermediary position of overseas migrants – positioned between the majority population and international migrants – plays at objective and subjective levels. The combined effects of their racial categorization as Black, the within-variations related to perceptions of their skin color, and the legitimacy granted by their long-held French citizenship, shapes their socioeconomic and symbolic positions within the French social stratification.

Marketing de relacionamento e cultura organizacional : uma perspectiva interorganizacional

Larentis, Fabiano January 2010 (has links)
Relacionamentos interorganizacionais são complexos e multifacetados, por sua natureza não apenas econômica, mas social e cultural. Por sua vez, estratégias de Marketing de Relacionamento não apenas possibilitam vantagens competitivas sustentáveis, mas podem interferir nos sistemas de símbolos e significados de organizações diferentes, através da frequência e qualidade das interações e pela existência de confiança, comprometimento, cooperação e aprendizados comuns. Considerando os fundamentos e práticas do Marketing de Relacionamento, o Marketing como área de fronteira dentro das organizações e as características e processos atinentes à Cultura Organizacional, este estudo teve como propósito analisar a contribuição dos relacionamentos interorganizacionais, especificamente entre fornecedores e clientes, nas suas transformações culturais organizacionais. Assim, tendo uma revisão literária na qual se abordaram a Cultura Organizacional, o Marketing de Relacionamento e as fronteiras organizacionais, foi efetuado um estudo qualitativo de casos múltiplos. Participaram da pesquisa funcionários e intermediários de canais de marketing de uma empresa moveleira (intitulada Empresa M) e de uma empresa de prestação de serviços financeiros (intitulada Empresa S). Foram realizadas quarenta e seis entrevistas em profundidade e uma observação, em quatro fases de pesquisa: a primeira e a terceira fases na Empresa M (vinte e seis entrevistas e uma observação), e a segunda e quarta na Empresa S (vinte entrevistas). A análise de dados utilizada foi a baseada na grounded theory. Os resultados indicam a importância da confiança, do comprometimento, da cooperação e dos processos de aprendizagem nas transformações das culturas organizacionais envolvidas; a importância destas dimensões na continuidade dos relacionamentos e na redução dos conflitos de papel dos interfaceadores; o papel da rotatividade e dos símbolos e significados não compartilhados em enfraquecer essas dimensões e respectivas relações. Por fim, evidenciam a existência de uma cultura interorganizacional, um sistema de símbolos e significados partilhados, por grupos ou indivíduos de organizações diferentes, de forma transitória ou específica a determinadas questões (perspectiva cultural da fragmentação). / Interorganizational relationships are complex and multifaceted, by its nature not only economic but social and cultural. In turn, Relationship Marketing strategies not only allow sustainable competitive advantages, but can influence the systems of symbols and meanings of different organizations, through the frequency and quality of interactions and the existence of trust, commitment, cooperation and learning processes. Considering the fundamental practices of Relationship Marketing, the boundary characteristics of Marketing in organizations and the characteristics and processes related to organizational culture, this study aimed to analyze the contribution of interorganizational relationships, specifically suppliers and customers, to the changes in organizational cultures. Therefore, considering a literature review in which was addressed Organizational Culture, Relationship Marketing and organizational boundaries, it was made a qualitative multiple-case study. The participants were employees and marketing channels intermediaries of a furniture company (called Company M) and a financial services company (called Company S). Forty-six in-depth interviews and one observation were made, at four phases of research, the first and third phases in Company M, with twenty-six interviews and the observation, and the second and fourth in the Company S, with twenty interviews. The data analysis used was based on grounded theory. The results indicate the importance of trust, commitment, cooperation and learning processes in the changes of organizational cultures considered, the importance of these dimensions in the relationships continuity and boundary spanners’ role conflicts reduction and the role of turnover unshared symbols and meanings in weakening these dimensions and their relations. Finally, demonstrate the existence of interorganizational culture, a system of symbols and meanings shared by groups or individuals from different organizations, on a temporary way or specific to certain issues (culture perspective of fragmentation).

Machine Learning to Discover and Optimize Materials

Rosenbrock, Conrad Waldhar 01 December 2017 (has links)
For centuries, scientists have dreamed of creating materials by design. Rather than discovery by accident, bespoke materials could be tailored to fulfill specific technological needs. Quantum theory and computational methods are essentially equal to the task, and computational power is the new bottleneck. Machine learning has the potential to solve that problem by approximating material behavior at multiple length scales. A full end-to-end solution must allow us to approximate the quantum mechanics, microstructure and engineering tasks well enough to be predictive in the real world. In this dissertation, I present algorithms and methodology to address some of these problems at various length scales. In the realm of enumeration, systems with many degrees of freedom such as high-entropy alloys may contain prohibitively many unique possibilities so that enumerating all of them would exhaust available compute memory. One possible way to address this problem is to know in advance how many possibilities there are so that the user can reduce their search space by restricting the occupation of certain lattice sites. Although tools to calculate this number were available, none performed well for very large systems and none could easily be integrated into low-level languages for use in existing scientific codes. I present an algorithm to solve these problems. Testing the robustness of machine-learned models is an essential component in any materials discovery or optimization application. While it is customary to perform a small number of system-specific tests to validate an approach, this may be insufficient in many cases. In particular, for Cluster Expansion models, the expansion may not converge quickly enough to be useful and reliable. Although the method has been used for decades, a rigorous investigation across many systems to determine when CE "breaks" was still lacking. This dissertation includes this investigation along with heuristics that use only a small training database to predict whether a model is worth pursuing in detail. To be useful, computational materials discovery must lead to experimental validation. However, experiments are difficult due to sample purity, environmental effects and a host of other considerations. In many cases, it is difficult to connect theory to experiment because computation is deterministic. By combining advanced group theory with machine learning, we created a new tool that bridges the gap between experiment and theory so that experimental and computed phase diagrams can be harmonized. Grain boundaries in real materials control many important material properties such as corrosion, thermal conductivity, and creep. Because of their high dimensionality, learning the underlying physics to optimizing grain boundaries is extremely complex. By leveraging a mathematically rigorous representation for local atomic environments, machine learning becomes a powerful tool to approximate properties for grain boundaries. But it also goes beyond predicting properties by highlighting those atomic environments that are most important for influencing the boundary properties. This provides an immense dimensionality reduction that empowers grain boundary scientists to know where to look for deeper physical insights.

Esthétique des limites. Espaces du savoir chez Novalis et Mallarmé / Aesthetics of Boundaries. Spaces of Knowledge in Novalis and Mallarmé

Krilles, Peter 04 December 2009 (has links)
La proximité entre les écrits de Novalis et de Mallarmé est aujourd’hui un lieu commun de la recherche sans pour autant avoir fait l’objet d’une étude approfondie. Si une influence directe ne saurait être affirmée avec certitude, le simple constat d’une modernité commune est également insuffisant. La parenté entre les deux projets esthétiques se situe à un autre niveau. Dans les contextes de crise des années autour de 1800 et de la seconde moitié du XIXe siècle, les deux auteurs esquissent une conception de l’art qui vise une réorganisation des espaces du savoir de l’âge moderne. Le dispositif central de cette ‘troisième voie’ est celui de la limite qui permet de rompre avec la vanité d’une approche représentative de l’expérience esthétique. L’esthétique des limites de Novalis et de Mallarmé ne se restreint pas au simple constat de la négativité qui résulte des nombreuses limites fondamentales auxquelles l’être humain moderne se trouve confronté. Les deux auteurs ne considèrent pas en premier lieu la limite dans sa fonction de délimitation, mais comme un espace propre qui revêt une productivité et une fonctionnalité épistémologiques considérables. Selon eux, la limite est une configuration essentielle de l’expérience esthétique parce qu’elle confère à celle-ci une médialité et une performativité spécifiques qui permettent de dépasser la relation binaire entre la discursivité du savoir positif et l’inaccessibilité d’un savoir absolu. Ainsi, l’esthétique des limites est une conception particulièrement pertinente à l’époque actuelle où le débat sur la valeur épistémologique de l’art et de la littérature est loin d’être terminé. / The similarity between the writings of Novalis and Mallarmé has become a topos in research, however, it has never been the object of a detailed study. On the one hand, we cannot say that Mallarmé was directly influenced by Novalis, on the other, the declaration that they share a modern vision is just as insufficient. The connection between the two aesthetic projects has to be found on another level. In their respective contexts of crisis, that characterise the periods around 1800 and the second half of the 19th century, both poets outline a conception of art with the objective of a new organisation of modern spaces of knowledge. Boundaries are a central dispositive of this ‘third way’ because they make it possible to overcome the vanity of a representative conception of aesthetic experience. Novalis’ and Mallarmé’s aesthetics of boundaries do not confine themselves to simply assessing the negativity that results from the numerous fundamental limitations of modern human condition. Both of them do not primarily consider the phenomenon of boundary to be a mere function of delimitation. For Novalis and Mallarmé, a boundary is an autonomous space that possesses a high epistemological productivity and functionality. Boundaries are central configurations of aesthetic experience because they endow this experience with a specific mediality and performativity that allow to overcome the binary relationship between positive discursive knowledge and the unattainability of absolute knowledge. The aesthetics of boundaries are an important concept nowadays as the debate surrounding the epistemological relevance of art and literature is far from being finished.

Coping with boundaries - A study on the interaction between work and non-work life in home-based telework

Kylin, Camilla January 2007 (has links)
<p>The increase of women’s labor force participation, the diversity of family constellations, many men’s increased participation in childcare, and the development of flexible working arrangements have stimulated research on the relationship between work and non-work. In this thesis, the interaction between work and non-work is examined in the case of home-based telework, an example of flexible working arrangement. Because of the disappearance or blurring of the traditional boundaries in time and space, the consequences of these working conditions for individuals need to be analyzed. The overall aim of this thesis is to study the interaction between work and non-work in home-based telework and to analyze the following issues:</p><p>- conflict versus facilitation as related to the segmentation and integration of work/non-work domains</p><p>- the nature and role of boundaries</p><p>- the physical and mental aspects of work activities within the domains</p><p>The thesis is based on quantitative as well as qualitative data. In general, the results show that the domains of work and non-work do interact with each other in various ways and dimensions. The employees reported some degree of overlap spatially, temporally, and mentally, and limited overlap was preferred by the majority. The results show the importance of boundaries, as they are needed in order to bring structure and legitimacy to the work (carried out in the home/private domain) and to detach from work. The teleworking women reported less effective restoration than the non-teleworking women, while the teleworking men reported slightly more effective restoration than the non-teleworking men. Generally, the results showed that work tended to intrude more on family and non-work than vice versa. Individuals who experienced conflict between the domains of work and non-work also reported a lower degree of life satisfaction. Significant associations were found between facilitation (positive spillover) and life satisfaction and recovery.</p>

Ideals and boundaries in Algebras of Holomorphic functions

Carlsson, Linus January 2006 (has links)
We investigate the spectrum of certain Banach algebras. Properties like generators of maximal ideals and generalized Shilov boundaries are studied. In particular we show that if the ∂-equation has solutions in the algebra of bounded functions or continuous functions up to the boundary of a domain D ⊂⊂ Cn then every maximal ideal over D is generated by the coordinate functions. This implies that the fibres over D in the spectrum are trivial and that the projection on Cn of the n − 1 order generalized Shilov boundary is contained in the boundary of D. For a domain D ⊂⊂ Cn where the boundary of the Nebenhülle coincide with the smooth strictly pseudoconvex boundary points of D we show that there always exist points p ∈ D such that D has the Gleason property at p. If the boundary of an open set U is smooth we show that there exist points in U such that the maximal ideals over those points are generated by the coordinate functions. An example is given of a Riemann domain, Ω, spread over Cn where the fibers over a point p ∈ Ω consist of m &gt; n elements but the maximal ideal over p is generated by n functions.
