Intellectual disability and being human: a care ethics model

Rogers, Chrissie January 2016 (has links)
No / This pioneering book, in considering intellectually disabled people's lives, sets out a care ethics model of disability that outlines the emotional caring sphere, where love and care are psycho-socially questioned, the practical caring sphere, where day-to-day care is carried out, and the socio-political caring sphere, where social intolerance and aversion to difficult differences are addressed. It does so by discussing issue-based everyday life, such as family, relationships, media representations and education, in an evocative and creative manner. This book draws from an understanding of how intellectual disability is represented in all forms of media, a feminist ethics of care, and capabilities, as well as other theories, to provide a critique and alternative to the social model of disability as well as illuminate care-less spaces that inhabit all the caring spheres.

An Introduction to S(5,8,24)

Beane, Maria Elizabeth 01 June 2011 (has links)
S(5,8,24) is one of the largest known Steiner systems and connects combinatorial designs, error-correcting codes, finite simple groups, and sphere packings in a truly remarkable way. This thesis discusses the underlying structure of S(5,8,24), its construction via the (24,12) Golay code, as well its automorphism group, which is the Mathieu group M24, a member of the sporadic simple groups. Particular attention is paid to the calculation of the size of automorphism groups of Steiner systems using the Orbit-Stabilizer Theorem. We conclude with a section on the sphere packing problem and elaborate on how the 8-sets of S(5,8,24) can be used to form Leech's Lattice, which Leech used to create the densest known sphere packing in 24-dimensions. The appendix contains code written for Matlab which has the ability to construct the octads of S(5,8,24), permute the elements to obtain isomorphic S(5,8,24) systems, and search for certain subsets of elements within the octads. / Master of Science

Beyond Consensus: A Rhetorical Genre Analysis of the Mountain Valley Pipeline's 401 Public Hearings

Scarff, Kelly 10 June 2021 (has links)
This study seeks to understand public and institutional uptake of the public hearing genre. More specifically, this study examines how public hearing genre conventions are established and how those conventions inform and often govern tensions that arise in public discourse about a contested environmental project. In my research, I analyzed a corpus of public comments from two Mountain Valley Pipeline (MVP) 401 Water Quality Certification public hearings that were held in August 2017 and hosted by Virginia Department of Environmental Quality (VA DEQ). Additionally, I conducted interviews with 13 community members and two state representatives who spoke at one of the two hearings. This approach led me to several important findings. Most significantly, I found that while many community members understood VA DEQ's stated purpose of the public hearings, they prepared comments that spoke to an entirely different purpose because they were responding to a different kind of problem than that of VA DEQ. This finding is crucial to understanding the other tensions and ideas of consensus that occur among citizens and VA DEQ representatives since the kind of problem informs the uptake of the public hearing and the overall interpretation of the public hearing genre. My dissertation thus argues that there are ways we might reimagine ideas of effectiveness, consensus, and the public hearing genre, specifically in the case of the 401 Public Hearings and more generally in other public hearings where public discourses center on a contested environmental project like the MVP. / Doctor of Philosophy / This study examines the role and effect of public hearings and the tensions that sometimes arise within them.

Schémas compacts hermitiens sur la Sphère : applications en climatologie et océanographie numérique / Hermitian compact schemes on the sphere : applications in numerical climatology and oceanography

Brachet, Matthieu 03 July 2018 (has links)
L’enjeu de la simulation de la dynamique atmosphérique et océanographique a pris ces dernières années une importance accrue avec la question du réchauffement climatique. Le modèle à simuler est complexe. Il combine les équations de la mécanique des fluides avec celles de la thermodynamique. Au 19ème siècle, le mathématicien Adhémar Barré de Saint-Venant formule un système d’équations aux dérivées partielles décrivant les mouvements d’un fluide soumis à la gravité et de faible épaisseur. Il s’agit des équations Shallow Water. L’objectif de cette thèse est de développer et d’analyser un algorithme de résolution des équations Shallow Water sur une sphère en rotation. Dans un premier temps, j’étudie différents aspects mathématiques des opérateurs aux différences finis utilisés par la suite en géométrie sphérique. Les schémas aux différences obtenus sont utilisés pour résoudre l’équation de transport, l’équation des ondes et l’équation de Burgers. Les propriétés de stabilité précision et conservation sont analysées. Dans un second temps, la grille Cubed-Sphere est introduite et analysée. La structure de ce maillage est analogue à celle d’un cube. L'interprétation de la Cubed-Sphere à l’aide de grands cercles permet de construire des opérateurs sphériques discrets gradient, divergence et vorticité d'ordre au moins égal à 3 (en pratique d'ordre 4). La troisième partie de la thèse est dédiée à différents tests pour le système d’équations Shallow Water ainsi que pour l’équation d’advection. Les résultats démontrent une précision proche de celle obtenue par les algorithmes conservatifs d'ordre 4 les plus récents / The problem to obtain accurate simulations of the atmospheric and oceanic equations has become essential in recent years for a proper understanding of the climate change. The full mathematical model to simulate is rather complex. It consists of the coupling of several equations involving fluid dynamics and thermodynamics. In the 19th century, Adhémar Barré de Saint-Venant first formulated the equations describing the dynamic of a fluid subject to gravity and bottom topography. This system is Shallow Water equations. The goal of this thesis is to develop and analyze a numerical scheme to solve the shallow water equation on a rotating sphere. First, a mathematical analsysis of finite difference operators that will be used on the sphere is presented. These schemes are then used to solve various equations in a spehreical setting, in particular the advection equation, the wave equation and the Burgers equation. Stability, accuracy and conservation properties are studied. In a second part, I consider in detail the Cubed-Sphere grid. This particular spherical grid has the mesh topology of a cube. Another interpretation makes use of great circles, this allows to obtain spherical discret operators gradient, divergence and curl of a preved third order. These operators are numercially of 4th order. Numerial results are show in particular for the SW equations an acurracy similar to the one of conservative schemes of 4th order published recently

Formering för offentlighet : Kvinnokonferenser och Svenska Kvinnornas Nationalförbund kring sekelskiftet 1900

af Petersens, Lovisa January 2006 (has links)
The thesis considers three women conferences arranged by the National Council of Women of Sweden (NCWS) in Stockholm at the turn of the 20th century. NCWS was a branch of the International Council of Women and at its height it was an umbrella-organisation for about forty Swedish women organisations. The focus is on the role of the conferences as arenas for women who wanted to prove their ability and competence in society. The content, the form and the function of the conferences are analysed. The question whether the conferences arranged by the NCWS reflected the ideas, dilemmas and strategies of the bourgeois women’s movement is addressed. A larger historical development is illuminated – the formation of the bourgeois women movements for the public sphere in the process of modernity. The thesis explores different theories and shows how the concepts of class, gender, public sphere, modernity and trans-nationalism were dealt with at the conferences. The women conferences have been treated as manifestations; as a quintessence of the ideas and ambitions of the movement. The thesis asserts that the ideology of the movements was formulated and expressed not only in spoken words, but also in festivities, symbols and sisterhood. The class identity was manifested in the form of which the conferences were conducted. On the one hand, the conference women showed loyalty to the conservative society and the rigid class position. On the other hand, the conference initiators wanted to improve women’s opportunities of becoming citizens and to move the boarders between the public and the private. Ideologies such as Internationalism and Scandinavism became important in creating a collective identity.

Modernization And Women In Tunisia: An Analysis Through Selected Films

Coskun, Cicek 01 September 2006 (has links) (PDF)
This study analyzes the representation of women and modernization in Tunisian society by looking at Tunisian films produced in Tunisia after 1980. Study aims to develop a new concept to understand modernization process of women in a non-western, Muslim, and North African society through representations in films. Women&rsquo / s modernization process has been analyzed through the qualitative analyses of five Tunisian films by focusing on conceptualization of women issue as one of the main elements of Tunisian modernization. More presicely, the study examines stages of women&rsquo / s modernization on the one side, and representation of this process in films on the other. In conclusion, I argue that examining written literature alone is not enough to understand women&rsquo / s modernization process in a non-western society. Expansion of modernization is not rapid and equal in the Tunisian society. If taking place in the public sphere, having a paid job and having education are taken as the indicators of women&rsquo / s modernization, it is seen that lower class women face with problems in every stage of Tunisian modernization. At that point, attending to visual sources like cinema which has the ability to reflect the society can give us convenient information about this process.

Between the Mediated and the Performed : an empirical contribution to understanding Arabic public spheres

Dajani, Deena January 2010 (has links)
The notion of a nascent Arabic public sphere vis-à-vis the region s transnational news networks has been at the centre of much debate. However, this debate is met with little empirical grounding as well as a conceptual limitation to discussing political publics. This thesis seeks to contribute to and inform current debates by means of an empirical exploration of Arabic public spheres across the mediated-political realm of news media as well as the performative-cultural sphere of interactive theatre. The Jordanian parliamentary elections of November 2007 offer a framework for the research which is made up of two case studies. The first case study examines the portrayal and representation of Jordanian citizens in the news coverage of the parliamentary elections. Four transnational broadcasters (al-Jazeera, al-Arabiya, al-Hurra and JTV) were monitored during the lead up to and post the elections (over a month s duration) and different modes of participation were identified in the coverage. The second case study explores the ways in which Jordanian citizens participated in interactive theatre performances about the elections across Jordan. The performances were specifically developed to ellicit responses from audiences in the form of discussion as well as role playing (in which the audiences assume the roles of citizens in a town hall meeting). Results from the two case studies revealed significant differences in the ways in which citizens participated, or were portrayed as participating, across the political and cultural spheres. The transnational media portrayed citizens largely as observers of the political process and, less frequently, as commentators on issues of public concern. The mediated public sphere was also found to be gendered and afforded Jordanian women less presence and access to participate. On the other hand, the cultural public sphere afforded citizens spaces to discuss issues of public concern as well as contest dominant and exclusionary narratives within their societies. Jordanian women were also found to negotiate change through the reinterpretation of the symbolic. These findings demonstrate that confining our understanding of Arabic public spheres to the political-mediated marginalises the diverse ways in which citizens do participate, particularly so in the case of women.
