La thèse étudie la question du rapport à la matière des artistes britanniques et de leurs critiques à différentes étapes de la fin du dix-huitième siècle au début du vingtième siècle. Au coeur de ce travail de recherche se trouve la notion de texture, pensée comme outil critique renvoyant à la fois à la surface peinte des oeuvres et à leur iconographie. La thèse démontre que la matérialité apparaît comme une dimension fondamentale de ce qui fait la spécificité de la peinture britannique. La notion de texture, conçue comme concept plastique plus qu'essentialiste, permet de rendre compte de certaines tendances persistantes qui structurent la création artistique, la pensée théorique et le débat critique en Grande Bretagne. Sur la période observée, nombreux sont les artistes qui s'attachent à faire sentir la vérité des phénomènes naturels et le vernaculaire dans leur tangibilité. Aussi, l'approche profondément concrète de la nature (humaine et végétale) par les peintres britanniques rend compte du rapport direct qui s'opère dans leur peinture entre matière observée et matière représentée. La conscience des matériaux et du matériel, telle que la révèle le discours critique, est au centre des problématiques du champ artistique en Grande Bretagne. En historicisant ce rapport à la matière, il s'agit d'inscrire la question de la texture dans un contexte épistémologique — qui lie création artistique et empirisme — et dans un rapport, excentrique, à la modernité. Cet angle d'approche permet de relier différentes périodes trop souvent perçues comme étanches et en ce sens de porter un regard nouveau sur l'art britannique / This dissertation looks at how the meaning of the painted surface engaged artists and critics in contemporary discourses at different stages between the late eighteenth century and early twentieth century. At the heart of this research project is the notion of texture, thought of as a critical tool, referring both to the painted surfaces of artworks and to their iconography.This dissertation demonstrates that the concept of materiality is a productive optic through which the history of British art can be read. The notion of texture, conceived as a plastic concept rather than an essentialist one, allows for the identification of persistent tendencies structuring artistic creation, theoretical thinking and critical debates in Great Britain. In the period under focus, there are numerous artists who consistently try to capture the truth of natural phenomena and the tangibility of the vernacular. Thus, British painter's profoundly concrete approach to nature (human or topographical) testifies to the direct links which are created in their paintings between observed and represented matter. The consciousness of materials and of materiality, as revealed by critical discourses, is at the centre of artistic debates in Great Britain. By historicizing the approach to matter, I situate the question of texture in an epistemological context linking artistic creation to empiricism. Considered in this way, texture takes on an eccentric relationship to modernity. This prism of study allows me to link different periods too often perceived as watertight and therefore to offer a new outlook on British art.

This thesis addresses these problems. (1) A clear understanding of the conceptual approach is prerequisite for teaching children to think creatively. (2) The conceptual approach has been misunderstood because educators have not distinguished clearly between the terms "creative" and "creatively." (3) The conceptual approach has been misapplied because educators have lost sight of the essence of the philosophies at the heart of the method. (4) The core of truth necessary for understanding teaching for concepts can be understood by tracing philosophical thought and application of the approach from the Renaissance to 20th Century America. (5) Inconsistencies in interpretations and applications of teaching for concepts have made it difficult for contemporary teachers to identify a single model to follow.

Self-care is a central concept in heart failure management and nursing practice. Yet, the uptake of heart failure self-care has been uncritical and detached from broader contexts. Therefore, heart failure self-care was explored using Rodger’s evolutionary concept analysis approach to identify antecedents, attributes, and consequences with attention to context, time, application, and meaning. The analysis suggests that heart failure self-care tends to focus on individual behaviours to the detriment of social and structural determinants of health. It also shifts responsibility away from the healthcare system and onto the individual. Moving forward, a more robust conceptualization of heart failure self-care is needed or possibly, the development of a new concept that focuses beyond the self. / Graduate / 2022-12-15

Within the framework of ecological psychology, environments are places, defined as landscapes of affordances, or the array of potential actions that can be executed. The feedback between direct perception-action and use of affordances results in the sense of presence in place. According to previous research, increased presence has been correlated with greater attachment and connectedness with the place as well as beneficial psychological states in a campus setting. However, it is unclear what factors, such as demographics, may influence differences in engagement with campus affordances, and hence, presence among individuals. The aim of the study is to investigate the relationship between campus presence, demographic factors, and social self-concept. Participants completed a survey that assessed their demographics, aspects of self-concept, degree of campus engagement and their sense of presence on campus.

The field of interaction design is in constant movement due to the fact that what we design is interactions over time. These interactions often involve di-gital and networked technologies that are based on interchangable software.  These changes often happen at a speed that is imperceivable to us. What if instead of going with this flow, we slow down, or even rewind?This thesis aims to revisit some of the meanings of core concepts in interacti-ve technologies, such as software, hardware, network, screen and application, in order to draw a link between these concepts and their historical entangle-ments with textiles and weaving. The concepts point the attention towards some very specific textile practices like, a net (knotted or woven structure); a screen (partition, filter, screen-printing); softwares (textile merchandise); and application (decoration sewn onto textile).Moving between the literal and figurative senses of the words, the chosen concepts are materialized and activated through embodied interaction, in or-der to challenge their meanings and the things we take for granted in the field of interaction design.  The four variables material, structure, form and scale, are used as a framework to create and evaluate interaction aesthetics. The research largely builds on hands-on explorations and weaving as a way of knowing and doing interac-tion design.The tensions of innovation and tradition are used as drivers for explorations within a post-digital framework. By materializing central concepts into expe-riential artifacts, it allows us to see, feel and talk about other things. These are conversations that can hopefully contribute to a greater understanding of some of the foundational concepts in the field and open up to more meanings of doing and practicing interaction design.

This thesis studies competence of simplified simulation methods for boosting simulation.  The most efficient propulsion unit has higher amount of power compared to less efficient propulsion units in boosting. Boosting is relevant subject to study due to new concept. New concept allows a larger diameter for the propeller which increases the efficiency of the propeller. New concept relies on the idea to have the propeller behind the hull.   The thesis is restricted to study displacement hulls from a point of view of propulsion efficiency. Large cruise ship model is utilized in this thesis to identify boosting related effects efficiently. Model tests reports of this concept are used as a baseline and a comparison material for two methods that are tested in this thesis. These methods are Matlab simulation code and OpenFOAM as the CFD software.   New propulsion arrangement concept is more efficient than current solutions for this hull type according to model tests. Trend of the CFD and Matlab simulation results matches well with model test results for boosting. Matlab simulation is evidently more time efficient solution than CFD simulation for boosting. Simplified CFD simulation is sufficiently accurate to study boosting concept with this research setup. Matlab and CFD simulations can be combined to obtain the most efficient solution to analyze the most effective load division for boosting.   Different types of hulls should be simulated and results should be verificated with model or full scale tests. In addition, ships with old two shaft arrangements could be converted to have two smaller pods and center line propeller in order to have better comparison with current methods. Scaling factors increases the uncertainty for new concepts; therefore full scale measurements are required. / Denna masteruppsats studerar möjligheterna med förenklade simuleringsmetoder i relation till nya framdrivningskoncept. Studerat koncept ger möjlighet till en större diameter för en boosterpropeller i centerlinjen, vilket ökar propellerns effektivitet. Konceptet bygger på tanken att få propellern bakom skrovet. Masteruppsatsen är begränsad till att studera deplacerande skrov i relation till framdrivningseffektiviteten. Studien appliceras på stora kryssningsfartyg. Resultat från modellförsök används som en referens och ett jämförelsematerial för de två beräkningsmetoder som testas i denna masteruppsats. Dessa metoder är Matlab-simuleringskod och OpenFOAM som CFD-programvara. Arbetet visar att det nya framdrivningskonceptet är effektivare än nuvarande lösningar för denna skrovtyp. Resultaten från CFD och simuleringsresultat från Matlab matchar väl med modellprovresultat. Matlab-simulering är en mer tidseffektiv lösning än CFD-simulering. Förenklad CFD-simulering är tillräckligt exakt för att studera boosterkoncept. Matlab- och CFD-simuleringar kan kombineras för att få den mest effektiva lösningen och för att analysera den mest effektiva belastningsfördelningen mellan propulsorer. Olika typer av skrov bör undersökas och resultaten ska verifieras med modell- eller fullskaletester. Skaleffekter ökar osäkerheten, därför krävs fullskalemätningar
