No. of bitstreams: 1 EDM - Marcia Yolanda Rosalves.pdf: 3135012 bytes, checksum: 57c3dae3f651e69ce218a2790d1f5f7b (MD5) Previous issue date: 2006-10-27 / This research involves the teaching and learning of the geometry of space (three-dimensional geometry) in school mathematics. It considers, in particular, the relationships between geometrical objects and their representations in the plane. The works of Parzysz (1988; 1993), which served as the theoretical base for this study, point to the difficulties students that experience in interpreting representations of three-dimensional objects, in terms of construction (codification) and interpretation (decodification), as well as the conflict between the poles of seeing and knowing. The results presented by Parzysz concern experimentations carried out in the conventional paper-and-pencil environment. Considering the limitations of this environment and the difficulties associated with the identification of spatial relations given its static nature, the dynamic geometry environment of Cabri 3D was chosen as the context for this study. The aim was to investigate the role of the dynamic representation of this software in the study of space geometry. More precisely, the study seeks to analyse the possibilities related to the poles of seeing and knowing in the interactions of subjects with the tools and representations of Cabri 3D. The empirical part of the research involved the development of an experimental study strongly inspired by the methodology of Design Experiments, using the perspective of Steffe and Thompson (2000) and Cobb et al. (2003). High school students from a public-sector school in the city of São Paulo participated in this experiment. The results show that, in certain situation, the loss in information associated with Cabri 3D representation of spatial objects are less than in the paper-and-pencil environment. The evidence also suggested that both the dynamic aspect with the potential to manipulate and change the point of view onto the object represented and the treatment the enriching of representations made possible by the use of the construction tools aided in the process of decodification, amplifying the interpretation of the drawing on the part of the student and enabling a better use of perceptive inferences / A presente pesquisa está inserida no contexto do ensino-aprendizagem da Geometria Espacial na Educação Básica, referindo-se, em particular, às relações entre os objetos geométricos e suas representações planas. Os trabalhos de Parzysz (1988; 1993) destacam as dificuldades dos alunos com a representação de objetos tridimensionais, no que se refere à sua elaboração (codificação) e interpretação (decodificação), bem como o conflito gerado pelos pólos do visto e sabido que são as bases do presente estudo. Os resultados apresentados nas pesquisas desse autor referem-se a experimentações no ambiente convencional de papel&lápis. Considerando as limitações desse ambiente e as dificuldades de identificação de relações espaciais dado seu caráter estático, optou-se por utilizar o ambiente de geometria dinâmica Cabri 3D. Assim, o estudo teve por objetivo investigar o papel das representações dinâmicas nesse software. Mais precisamente, pretendeu-se analisar as possibilidades de gestão dos pólos do visto e do sabido nas interações dos sujeitos com as ferramentas e representações do Cabri 3D. O desenvolvimento da pesquisa deu-se por meio de um estudo experimental fortemente inspirado na metodologia do Design Experiment na perspectiva de Steffe e Thompson (2000) e Cobb et al (2003), sendo realizado com alunos do Ensino Médio de uma escola pública da cidade de São Paulo. Os resultados mostraram que, em determinadas situações, as perdas de informações no Cabri 3D são menores que no ambiente papel&lápis. Existem também evidências de que tanto o aspecto dinâmico com possibilidades de manipular e mudar o ponto de vista do objeto representado como o de tratamento , enriquecimento da representação no uso das ferramentas de construção, auxiliam no processo de decodificação, ampliando a interpretação do desenho por parte dos alunos e levando-os a um melhor aproveitamento das interferências perceptivas

Afin d'améliorer les moyens d'observation en Haute Résolution Angulaire les télescopes acquièrent des diamètres de taille considérable. L'optimisation de ces grands télescopes de type E-ELT nécessite une caractérisation complète des sites devant les accueillir ainsi que des coupoles qui vont les abriter. En se basant sur une étude expérimentale effectuée sur le site du VLT (Paranal) on montre que la caractérisation verticale de la turbulence donnée par les profils de Cn2 et d'échelle externe est plus représentative des conditions réelles d'observation. Sachant, que le site qui va accueillir le futur E-ELT est à seulement quelques kilomètres de Paranal, les résultats vont servir à définir les spécifications des systèmes de compensation prévus pour cette nouvelle génération de grands télescopes. Cette étude a permis aussi la mise en évidence de la couche de surface et on a établi une estimation de son altitude et de son énergie. On montre que la couche de surface contribue significativement à la dégradation du front d'onde incident sur le télescope. Sa localisation près du sol soulève des questions sur son interaction avec les coupoles qui sont de même taille. LOTUCE un nouvel instrument développé dans le cadre de mon travail de thèse, a été proposé pour étudier l'interaction de cette couche de surface avec la coupole. En se basant sur la mesure des angles d'arrivée (AA) sur différents points du front d'onde, LOTUCE donne une estimation des paramètres optiques de la turbulence comme le paramètre de Fried, le temps de cohérence et l'échelle externe. La modélisation de la turbulence locale est alors possible en étudiant les courbes de covariance des AA dans les deux directions longitudinale et transverse. La dernière partie de ce travail a porté sur l'évolution temporelle de la turbulence optique. Il s'agit d'une étude basée sur l'estimation du temps de cohérence à partir de l'analyse statistique des fluctuations d'AA. Cette méthode utilisée par GSM a été validée par une simulation numérique. Ces résultats montrent que ce paramètre est plus sensible aux conditions de mesures et aux contraintes instrumentales.

The present work is a new attempt to interpret on the episode in Genesis 18:1-15 by the method of narrative criticism. The general tendency on the narrative had focused on the exemplary act of Abraham’s hospitality interpreting it as his righteousness by the perspective of NT (Heb 13:2) or by the test motive of Greek Myth (the birth of Orion). The retributive theology was considered too much in interpreting the Fellowship narrative (Gn 18:1-15).These interpretations conflict with the narrator’s own theological views: (1) righteousness by faith (Gn 15:6), (2) God’s mercifulness to save Lot (Gn 19:29), and (3) God’s being gracious to make Sarah conceive (Gn 21:1). This study attempts to find out the author’s own interpretative view indicated in the whole Abraham narrative (Gn 11:27-25:11) as well as in the Fellowship Narrative itself (Gn 18:1-15).The present work is an attempt to interpret on the narrative by the method of narrative criticism. This study pays attention to the narrator’s various literary skills: “linking structure with preceding episode” (Gn 18:1a); “Sandwiched structure” of the larger context (Gn 18:1-21:7); Unique Plot Sequence; and Repeated Clue word and phrase (“laugh,” “Sarah,” ”this time next year”). These literary skills are understood to indicate the faithfulness of the Lord who tries to fulfill what he promised. The conclusion of this study overturns the traditional interpretations on the Fellowship Narrative. This work attests that Abraham showed his righteousness not by doing hospitality but by obeying God’s new command of circumcision out of willing heart as he used to obey the Lord’s commands having faith in the promise of the Lord (ch.5.3.2.2). The motive of God’s visit is to have the covenantal fellowship with obedient Abraham (ch. 2.1.6; 2.1.6.1). Abraham’s first moment recognition of deity is attested by interpreting of the technical pair verb, “And he lifted up his eyes and he saw and Lo!” (Gn 18:2a), which depicts prophetic experience of Abraham (ch.3.3). Abraham’s manner for the visitors is relevant to the higher ones (ch.3.3.2.1). The futile human endeavor without having faith is considered as the reason of being delayed of fulfillment of God’s promise (Gn 16). The fulfillment of the promised son was not attained by any human effort, but only by God’s merciful intervention in the Abraham narrative (ch. 4.4.4 and 4.4.5). / Thesis (PhD)--University of Pretoria, 2010. / Old Testament Studies / unrestricted

The aim of the work is to present the possibilities of ethics in late Wittgensteinian framework. In course of the investigation will be presented: (1) early Wittgensteinian ethics, (2) late Wittgensteinian anti-foundationalism and (3) its consequences for analytical meta-ethics - it will be argued (a) against epistemologization of ethics and (b) for need of more complex understanding of ethics, by which traditional meta-ethical disputes of realism with anti-realism and of cognitivism with non-cognitivism will be overcame -, which will result in (4) development of late Wittgensteinian ethics. Ethics will be presented as consisting in ethical ways of seeing of the world, through which various phenomena arise as ethically relevant and late Wittgensteinian ethical investigation will be developed as clarification, cultivation and enrichment of our ethical ways of seeing in overall - partially subjective and partially intersubjective - context of language, life forms and life stories from which they arise. Keywords Ethics, meta-ethics, Wittgenstein, anti-foundationalism, truth in ethics, aspect seeing, perspicuous representation, ethics as clarification, life forms

This diploma thesis deals with landscape as a way of seeing, its critique and its defense. The thesis will initially focus on the presentation of the critical concept of ways of seeing by English art critic and writer John Berger. On the basis of this, the thesis will move to the exploration of the critical concepts of landscape and landscape painting by British humanistic cultural geographer Denis E. Cosgrove and American visual theorist and philosopher W. J. T. Mitchell. Subsequently, it will also deal with the relationship of these concepts to the concept of landscape by English historian and art historian Simon Schama. Cosgrove and Mitchell both deal in a similar way with the critical reflection of the idea of landscape in terms of postmodern and postcolonial criticism. Both authors are influenced by Berger's concept and claim that our aesthetic perception of landscape is not a natural vision, but an acquired, historically created way of seeing. This way of seeing then raises a number of questions in relation to the traditional conception of landscape aesthetics and can lead to a rethinking of traditional concepts such as aesthetic attitude, psychical distance or the idea of disinterested pleasure. Opposite to it, the thesis intends to present an optimistic concept of landscape by Schama. The...

This research delves into the complex themes of perception, art, and self in Oscar Wilde's novel "The Picture of Dorian Gray." Drawing from Wilde's philosophy of "Art for Art's Sake," the study explores the characterization of Dorian Gray through the perspectives of Lord Henry and Basil Hallward. The central question revolves around whether Henry's and Basil's individual understanding of Dorian accurately represents his true nature and how this perception influences the protagonist. To establish the philosophical foundation, Wilde's essays "The Decay of Lying" and "The Critic as Artist" are analyzed, highlighting the concepts of art, critique, and the artist. The symbolic significance of the portrait and mirror is examined, revealing their role in reflecting Dorian's duality and inner conflict but also working as an extention of Henry and Basil as Art Crtitics. By incorporating Ian Watt's theory of apprehension of reality, the paper explores the limitations of Henry and Basil in comprehending Dorian's true self. Dorian is viewed as a semi-art figure, both a work of art and a human being. The research aims to shed light on why Henry and Basil fail to truly see Dorian, ultimately enhancing our understanding of his characterization. Through a methodology encompassing close reading, analysis, and interpretation, this study contributes to existing scholarship by offering new insights into the intricate exploration of self-perception and the interplay between art and life in Wilde's only novel.

Trans Cinema and its Exit Scapes offers a critical and creative intervention into cultural representations of gendered body dissidence in contemporary film. The study argues for the possibility of finding spaces of “disidentification”, so-called “exit scapes” within the films. Exit scapes disrupt the dominant cinematic regime set up for the trans character, which ties them into stories of discrimination, humiliation and violence. In Trans Cinema, for instance films such as Hedwig and the Angry Inch (2001), Transamerica (2005), Romeos (2011) and Laurence Anyways (2012), scenes of singing, dancing and dreaming allow a different form of engagement with the films. As argued here, they allow a critical re-reading and an affirmative re-imagining of trans embodiment. The aim of this study is to investigate the utopian and hopeful potential within Trans Cinema from a critical transfeminist perspective. While focusing in particular on trans entrants as “spectators” or readers, this study draws on the work of a wide range of feminist and cultural scholars, such as Sara Ahmed, Susan Stryker, José Esteban Muñoz, Trinh T. Minh-Ha, Karen Barad and Donna Haraway. The thesis etches out cinematic spatiotemporalities that unfold possibilities of utopian worlding and trans becoming through a set of conceptual innovations. By utilising a critical approach to audio-visuality and feminist film theory, the thesis re-conceptualises haptic spectatorship theory and its critique in western modernist ocularcentricism through a set of conceptual innovations. The methodological tools developed in this thesis, such as the “entrant”, the “exit scape” and “sensible cinematic intra-activity”, feature here as a multisensorial methodology for transdisciplinary transgender studies and feminist film theory as well as visual culture at large. / Trans Cinema and its Exit Scapes är en kritisk och kreativ intervention med fokus på kulturella representationer av kroppar som bryter mot en könsbinär ordning i samtida film. Studien argumenterar för möjligheten att hitta utrymmen för “disidentification”, så kallade “exit scapes” inom filmerna. Exit scapes stör den dominanta filmiska ordning som skapats för transkaraktären, en ordning som är förbunden med berättelser om diskriminering, förödmjukelse och våld. Inom Trans Cinema, i filmer som exempelvis Hedwig and the Angry Inch (2001), Transamerica (2005), Romeos (2011) and Laurence Anyways (2012), öppnar scener med sång, dans och drömmar upp för andra former av engagemang med filmerna. Som det argumenteras för i avhandlingen tillåter dessa ett kritiskt omformulerande av, och ett nytt affirmativt sätt att föreställa sig, transkroppslighet. Syftet med den här studien är att undersöka den utopiska och hoppfulla potential som finns inom transfilm utifrån ett kritiskt transfeministiskt perspektiv. Även om studien främst riktar sig till trans entrants som “åskådare” eller läsare, så har den en bred teoretisk bas hämtad från verk av en lång rad feministiska forskare inom kulturfältet, såsom Sara Ahmed, Susan Stryker, José Esteban Muñoz, Trinh T. Minh-Ha, Karen Barad och Donna Haraway. Denna avhandling skissar filmiska spatiotemporaliteter, vilka öppnar för möjligheter av utopiska värdsliga och transsubjektiva tillblivelser genom utvecklandet av olika teoretiska begrepp. Genom ett kritiskt förhållningssätt till audiovisualitet och feministisk filmteori, revideras och omformuleras haptisk åskådarskapsteori och dess kritik i en västerländsk okularcentrism genom olika teoretiska innovationer. De metodologiska verktygen som utvecklas i avhandlingen, såsom “the entrant”, “the exit scape” samt “sensible cinematic intra-activity” utgör här funktionen som multisensorisk metodologi för transdisciplinära transstudier, feministisk filmteori samt för visuell kultur i stort.

Text in German / The society in developed countries is ever aging. Consequently, the proportion of the population living in retirement homes increases steadily. A central focus of pastoral counselling in retirement homes is the proclamation of the Gospel. However, many of their residents are affected by dementia. As the course of their disease progresses, their mental capacity decreases. This creates special tension for the counselling of residents of retirement homes. It moves in the tension field between counselling as proclamation of the word (Thurneysen) and focusing on dialogue as propagated by the pastoral care movement. Thus, the question arises of how the biblical message can be proclaimed to the affected people. This present research paper points out various approaches of dealing with people affected by dementia. Among these are activating approaches, such as occupational therapy, drawing or music therapy, reality orientation training, “warme zorg” (warm care) and security therapy. All of these approaches are related to the surroundings. Furthermore, approaches will be examined which influence the interaction with affected people: such as validation, person-centered care according to Tom Kitwood (2008), psychotherapy and maieutic listening. Finally, therapies will be considered which relate to the person and biography of people with dementia – such as reminiscence therapy, memory training and biography work. Moreover, the paper specifically investigates which particular features apply to small bible study groups in retirement homes. Eventually, it displays how affected people can be reached by hearing, seeing, smelling, tasting and sensing. In order to be able to stimulate the sense of hearing, one can include, for example, poems or sounds. The sense of vision is stimulated by pictures or symbols. Various flavors or foods appeal to the sense of smell. Skins and other objects activate the sense of touch. The findings gained from literature will be compared to praxis. For this purpose, various episodes will be documented using the empirical method of participating observation. All observations have been carried out in the Emil-Sräga Haus in Singen (Germany) where the author of this paper works as male nurse and counselor. / Practical theology / M.Th. (Practical theology)
