Microstructure and micro-mechanical characterization of as-built and heat-treated samples of Hastelloy X produced by laser powder bed fusion (LPBF) process has been carried out in this study. As-built LPBF blocks were solution heat-treated at 1177°C and 1220°C followed by fast cooling. The microstructure of as-built and heat-treated samples were studied by light optical microscopy, scanning electron microscopy, and electron backscatter diffraction. Instrumented indentation micro Vickers testing was performed to obtain microhardness and elastic modulus of asbuilt and heat-treated samples. Microtensile samples from as-built and heat-treated blocks were prepared and polished for mechanical characterization. Microtensile testing inside the scanning electron microscope was performed to evaluate the mechanical properties and to get information about the microstructural changes during plastic deformation. Microstructure characterization revealed disrupted epitaxial grain growth for the as-built samples whereas the two heated-treated Hastelloy X samples exhibited equiaxed grains with varying twin fractions. As-built Hastelloy X samples exhibited higher mean hardness than heat-treated samples. The yield strength of as-built samples reveals higher values as compared to conventional wrought Hastelloy X samples, whereas lower yield strength and higher elongation were observed for heat-treated samples as compared to as-built samples. Higher elongation and lower yield strength values were observed for the samples solution heat-treated at 1220°C compared to the solution heat-treated at 1177°C. Microstructural evaluation at different plastic strains during in-situ microtensile testing reveals a clear difference in dislocation density for as-built and heat-treated samples.

The aim of this research was to determine how Gestalt Therapy could be utilised to re-write life script. Transactional Analysis terminology was translated into Gestalt Therapy, especially the terms life script, life position and re-writing in the literature study. Gestalt Therapy concepts of importance for the research were also discussed in the literature study. An empirical study was conducted, involving one respondent, for whom Gestalt Therapy sessions were provided with the aim of determining how life script could be re-written through such intervention. Gestalt Therapy concepts and life script concepts were identified during the therapy process. A re-written life script was formulated by the researcher corresponding with the level of functioning of the respondent during therapy and in relation to the respondent's life position. The researcher deducts from the entire study, but especially from the empirical study that life script can be re-written by means of utilising Gestalt Therapy. / Social Work / M. Diac.

Innovare verso un modello per Intensità delle Cure (IdC) offre agli ospedali importanti potenzialità di miglioramento, tanto a livello di qualità delle cure quanto sul piano organizzativo e gestionale. L’introduzione del modello IdC può tuttavia implicare sostanziali modifiche nell’organizzazione sociale del lavoro clinico, modificando relazioni, confini e identità professionali. La tesi esamina i reciproci effetti tra il modello IdC e l’organizzazione sociale del lavoro ospedaliero. Il disegno di ricerca è organizzato in tre fasi: una estensiva analisi documentale, uno studio esplorativo basato su interviste qualitative semi-strutturate, uno caso di studio etnografico in profondità condotto in un ospedale recentemente organizzato secondo il modello IdC. I risultati sono organizzati in tre studi. Il primo mostra come il cambiamento IdC sia stato diversamente interpretato dai manager ospedalieri e dai clinici in prima linea con i pazienti, costituendo così due discordanti ‘narrative di cambiamento’. Il secondo studio si focalizza sugli ostacoli alla creazione di team multidisciplinari negli ospedali IdC. Il terzo studio esamina l’impatto del modello IdC su relazioni e confini professionali tra medici e infermieri. Oltre a contribuire alle teorie socio-psicologiche riguardo a confini e identità professionali, la tesi propone riflessioni concrete su come colmare il divario tra programmi innovativi formali e pratiche di cura quotidiane. / The Patient-Centred Model (PCM) is described as an attempt to redesign the hospitals around the needs of the patients, thus contributing to costs reduction, increased efficiency, and improved care. However, the introduction of the PCM may have a profound impact on the social organisation of work, changing lines of demarcation, challenging well established inter-/intra-professional relationships, and prompting the development of new roles and modes of working. This thesis explores the mutual effects between the new organisational model and the pre-existent social organisation of hospital work. The research design is organised in three phases: an extensive document analysis; an interview study; an in-depth ethnographic case study conducted for over one year in a PCM hospital. The findings are organised in three studies. The first shows that the PCM was interpreted differently by hospital managers and by frontline clinicians, thus giving rise to two divergent narratives of change. The second study focuses on the boundaries to collaboration and care integration in newly created hospital teams within PCM hospitals. The third study looks at the impact of the PCM on the medical-nursing boundary. The thesis contributes to management learning and practice by providing recommendations on how to accompany complex innovations, comprising of both their expected and unexpected consequences. It also enriches academic debates on professional boundaries, relations, and identities in healthcare.

This study investigates the representation of narrative space in the novel and the film of The Return of the King. As the two representations belong to two different mediums, the theories on narrative space in the novel and in the film are examined in order to distinguish between their modes of representation of space. In essence, the theory utilised for the spatial analysis focuses on the content, function and symbolic meaning within spaces, as created by the description of objects, the repetition and accumulation of spatial information, as well as the movement of characters within spaces and the interaction between characters and different spaces. This spatial interaction relates to the events, representations of time and the role of the narrator within the different dimensions of narrated space, that is, concrete and abstract space. The three most significant spaces within the novel and the film, namely Minas Tirith, Mount Doom and Hobbiton form the basis of the analysis, which focuses on the narrative spaces as they are represented. From this study, it becomes clear that there are different levels of meaning embodied within a space: the physical and geographical space, the social space of interaction and the abstract, symbolic space. The significant spaces and their meanings in the novel have been subjected to filmic transformation. Essentially, the spaces in both the novel and the film display the fact that space ultimately influences those events and people who interact with it and vice versa. These spaces thus embody specific meanings, which contribute towards the undertaken journey represented in Tolkien's fantastical, imaginative world. / MA (English), North-West University, Potchefstroom Campus, 2014

This dissertation examines three novels by the author and critic A.S. Byatt, namely Possession (1990), Babel Tower (1996) and The Biographer’s Tale (2000), using a hermeneutic method of analysis. The investigation pays specific attention to the structure of the novels and how this compares to the structure of the ancient palimpsest. Theoretical information on the palimpsest as model is based on relevant writings by Thomas Carlyle (1830, 1833), Thomas De Quincey (1845) through to Josephine McDonagh (1987), Gérard Genette (1997) and Sarah Dillon (2007). The ensuing argument is that Byatt’s use of postmodernist pseudo-intertextuality and intertextuality cause her novels to have a palimpsestic structure of various layers, with the effect that textual boundaries are transgressed. Ultimately Byatt’s writing strategies result in ontological uncertainty for the reader. / MA (English), North-West University, Potchefstroom Campus, 2014.

S’appuyant sur la sociologie des relations ethniques et de l’interactionnisme symbolique, ce mémoire vise à analyser la manière dont des femmes de culture musulmane engagées dans l’espace public québécois interagissent avec les stéréotypes par lesquels elles sont caractérisées dans la société, mais auxquels elles disent ne pas correspondre. Partant du postulat qu’il existe un discours dominant ethnicisant qui dépeint les femmes musulmanes comme des êtres « soumis » et « vulnérables », ces femmes engagées se voient assigner une identité dépréciative qu’elles ne partagent pas. Elles perçoivent donc un écart entre leur identité « réelle » qu’elles voudraient se voir reconnaître par autrui et l’identité « attribuée par autrui ». À partir d’entretiens semi-directifs, ce mémoire propose une typologie des femmes de culture musulmane engagées dans l’espace public québécois. Cette typologie permet d’analyser la manière dont celles-ci perçoivent le discours dominant et les réactions qu’il suscite chez elles. Les résultats de cette analyse suggèrent notamment que ces femmes engagées élaborent des stratégies identitaires afin de voir confirmer et renforcer l’identité qu’elles voudraient se voir reconnaître par la société majoritaire. La mise en place de ces stratégies révèle la porosité des frontières ethniques puisque certaines d’entre elles vont adopter des stratégies orientées vers la « similarisation » au majoritaire, alors que d’autres vont chercher à s’en différencier. / Based on the sociology of ethnic relations and symbolic interactionism, this master thesis aims at analyzing how women of Muslim culture involved in the Quebec public sphere interact with the stereotypes by which they are characterized in society but to which they do not associate themselves. Starting from the premise that there is a dominant ethnicizing discourse depicting Muslim women as being « submissive » and « vulnerable », these women are assigned a depreciative identity they do not share. They perceive a discrepancy between their own identity, which is the one they want to be perceived as, and their assigned identity.Starting from semi-structured interviews, this master thesis proposes a typology of women of Muslim culture involved in the public sphere. This typology is use to analyze how they perceive the dominant discourse and the reactions it evokes in them. The results suggest that these involved women develop identity strategies to confirm and reinforce the identity they wish to be recognized by the majority society. These strategies revealed the porosity of ethnic boundaries, since some of them will adopt strategies oriented to « similarisation » with majority while others will seek to differentiate themselves.

This thesis is centred on exploring the identity options and orientations of young British Indians, from Sikh and Hindu backgrounds, who are British born and living in the London area. Recent socio-political debates have assumed a lack of Britishness amongst these young people, an assumption that is rooted in the belief that high bonding capital within ethnic minorities has led to a lack of bridging capital. This thesis argues that such statements are an essentialisation of the reality of these young people. In fact, their sources of belonging are far more complex, and far less threatening than we may be led to believe. Through the utilisation of eighty in-depth interviews, this thesis presents the intricate social worlds of these young people and the range of orientations (positive and negative) they feel towards component parts of their social worlds, as well as examining the strength and permeability of boundaries that demarcate these social worlds. The final substantive chapter deals with Britishness, and uncovers and presents the different perceptions and understandings that these young people have about British national identity and the ways in which it is accommodated (or not) alongside other important sources of belonging. It is found that a multi-dimensional approach to identity and belonging is best suited to understand the diverse and highly individualistic trajectories of these young people and that 'diverse-dual identities' are the most common pattern of belonging in this particular empirical case. This thesis make a significant contribution to the existing theoretical frameworks on identity and assimilation as well as the current socio-political debates on Britishness and the cultural integration of ethnic minorities in Britain, by presenting data on an under-researched group, British Indians, and highlighting the range of experiences within this group and the sources of this diversity.

André MEYNIER, héritier de la géographie rurale française, étudia, avec le concours de la télédétection, les formes des parcellaires bocagers et y détecta ce qu’il nomma des « ellipses bocagères ». Il y consacra plusieurs articles, parmi lesquels «les ensembles cadastraux circulaires en Bretagne », dans les Annales de Bretagne, (Rennes, 1945) et «la genèse du parcellaire breton » (Norois, Poitiers, 1966). Après la révolution épistémologique de la géographie française des années 1960 et 1970, cet objet d’étude tomba progressivement en désuétude, sort qui fut d’ailleurs celui de la géographie rurale morphologique dans son ensemble. Dans cette thèse, cet objet – élargi à la notion de forme spatiale héritée, donc liée au temps historique long au sens braudélien – est exhumé pour en réexaminer la pertinence au regard des paradigmes de la géographie contemporaine. Comment insérer le temps long – parfois perçu comme permanence et immobilité, du moins à l’échelle de l’actualité – dans une géographie à vocation dynamique ? Comment les nouveaux courants géographiques auraient-ils pu s’emparer de cet objet qu’un regard rapide condamne à une accusation de passéisme ? Les réflexions engagées se veulent ouvertes à tous les courants de la géographie et n’en rejettent aucun. L’objectif est aussi de développer une dialectique disciplinaire qui transgresse les paradoxes apparents. Pour explorer ces problématiques, les formes spatiales héritées sont choisies non plus en Bretagne mais en France du Nord et au Benelux, où les espaces boisés, notamment ardennais, jouent un rôle majeur dans les limites de finages ; ce sont aussi des espaces frontaliers, ce qui permet la mise en relation avec des discontinuités. Cet espace, situé au seuil du monde Hercynien vaudra quelques escapades vers l’est où il se prolonge, engageant à un voyage vers le monde slave / André MEYNIER, one of the heirs of French rural geography studied the forms in partitioned bocage landscapes and with the help of remote sensing distinguished what he called enclosed landscapes ellipses. He dedicated several articles to them among which “les ensembles cadastraux circulaires en Bretagne” in les Annales de Bretagne (Published in 1945 in Rennes) and “la genèse du parcellaire Breton” (Published in 1966 in Norois). After the epistemological revolution of French geography in the 1960’s and 1970’s, this subject gradually became obsolete as well as classical rural geography as a whole. In this thesis, the subject of my study – broadened to the notion of Inherited Spatial Forms, and consequently connected to long historical time as Fernand Braudel defines it – is reexamined to evaluate its relevance when confronted to the paradigms of modern geography. Along with a geography intending to be dynamic, how could we bring long historical time into the equation when such a time is - on a recent scale at least - sometimes perceived as still and permanent ? How would new geographical streams have been able to express interest in this subject when it is often overlooked as a remnant of the past? The present reflection is meant to encompass all geographical streams without leaving any aside. The objective is also to develop a disciplinary dialectic that would go further than visible paradoxes. In order to delve into these problems, Inherited spatial forms were chosen not only in Brittany but in Northern France and in the Benelux as well, where wooded areas on the outskirts of villages, especially in the Ardennes, have a major role on defining the limits of said villages: they are also bordering areas allowing the link with discontinuities to be made. This region on the threshold of the Hercynian world will take us to an adventurous trip through Eastern Europe

Tendo em vista um cenário em que os dispositivos de registro do real adquirem onipresença na vida cotidiana, o jornalismo se encontra em um período de readequação de suas estratégias narrativas e de seu modus operandi. A presente tese procura investigar as reconfigurações no telejornalismo em razão da ubiquidade de câmeras, que capturam registros produzidos tanto pelas mídias quanto por instâncias externas a elas, e que oferecem aos veículos jornalísticos um material inesgotável e irrecusável, visto estar cercado de uma expectativa de autenticidade. Propõe-se então uma categorização às câmeras, sistematizadas como câmeras oniscientes e onipresentes, de modo a nos aproximarmos à especificidade do fenômeno. Em comum, todas as câmeras apontam à busca de uma estética realista, baseada no reconhecimento de uma baixa interferência midiática. Desse modo, o que se observa é o emprego de estratégias narrativas e estéticas para que o telejornalismo possa se apropriar destes conteúdos gerados por estas máquinas de visibilidade, que trazem às mídias algo que ficaria anteriormente restrito aos bastidores, operando também com sintoma da desfronteirização entre o público e o privado. A partir deste percurso metodológico, intenta-se por fim compreender de que forma estes dispositivos são utilizados para a concretização de novos efeitos de realismo ao jornalismo. / Considering a scenario where the technologic devices that visually register the world acquire omnipresence in everyday life, journalism is in a period of readjustment of its narrative strategies and its modus operandi. This research intents to investigate the changes in TV journalism because of the ubiquity of cameras, which capture images produced both by the media and by external institutions, since they offer to the journalistic enterprises an inexhaustible and irresistible material, because it is surrounded by an expectation of authenticity. We propose then a categorization of these machines, which are systematized as omniscient and omnipresent cameras, for the purpose of understanding the specificity of the phenomenon. In common, all of these cameras point to the search for a realistic aesthetics, based on the recognition of a low media interference. Thus, it is observed that the TV stations use some strategies to adapt these contents in their narratives, which bring to the media something that would previously be restrict to the backstage area. In a sense, they operate as a symptom o the erosion of the boundaries between public and private. With this methodological course, we finally attempt to understand how these technologic devices are used to achieve effects of realism to journalism.
