Secrets, silence and family narrative : Joy Kogawa's Obasan and Sky Lee's Disappearing moon cafe

Denomy, Jennifer. January 1997 (has links)
Both Joy Kogawa's Naomi Nakane and Sky Lee's Kae Ying Woo attempt to overcome silence and secrecy in order to reconstruct their families' histories, particularly their matrilinear histories. Their task is problematic: Naomi has no mother, and Kae has too many maternal figures battling for control. Both narrators approach their texts (and their searches for identity) with a degree of ambivalence. In Obasan, Naomi's uncertainty over the family identity she attempts to uncover manifests itself in the silences which pervade the text. Over the course of the novel, she pushes aside silence, in the process giving rise to two problematic issues at the work's centre: first, the adult Naomi who narrates must re-enter the experiences of her younger, silenced self; secondly, Naomi must overcome an oppressive silence in order to tell a story both centred around and driven by silence. / Whereas Naomi is reluctant to delve into her history, Kae is eager to recover what has been hidden from her. Instead of the numerous silences which pervade Obasan, Kae's growing ambivalence surfaces as narrative unreliability. Disappearing Moon Cafe is strongly mediated by Kae, who acknowledges the extent to which her authority is problematic; in reconstructing her past, she often reinvents it as well. / This paper explores the parallels between Naomi's and Kae's searches for family, and the ways in which similar journeys find radically different narrative expression. While the text of Obasan resists the tendency to inscribe the silences of its family narrative, Disappearing Moon Cafe battles its desire to fill in the blanks, to romanticize and invent.

Breaking Ground on the Moon and Mars: Reconstructing Lunar Tectonic Evolution and Martian Central Pit Crater Formation

January 2016 (has links)
abstract: Understanding the structural evolution of planetary surfaces provides key insights to their physical properties and processes. On the Moon, large-scale tectonism was thought to have ended over a billion years ago. However, new Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) high resolution images show the Moon’s surface in unprecedented detail and show many previously unidentified tectonic landforms, forcing a re-assessment of our views of lunar tectonism. I mapped lobate scarps, wrinkle ridges, and graben across Mare Frigoris – selected as a type area due to its excellent imaging conditions, abundance of tectonic landforms, and range of inferred structural controls. The distribution, morphology, and crosscutting relationships of these newly identified populations of tectonic landforms imply a more complex and longer-lasting history of deformation that continues to today. I also performed additional numerical modeling of lobate scarp structures that indicates the upper kilometer of the lunar surface has experienced 3.5-18.6 MPa of differential stress in the recent past, likely due to global compression from radial thermal contraction. Central pit craters on Mars are another instance of intriguing structures that probe subsurface physical properties. These kilometer-scale pits are nested in the centers of many impact craters on Mars as well as on icy satellites. They are inferred to form in the presence of a water-ice rich substrate; however, the process(es) responsible for their formation is still debated. Previous models invoke origins by either explosive excavation of potentially water-bearing crustal material, or by subsurface drainage of meltwater and/or collapse. I assessed radial trends in grain size around central pits using thermal inertias calculated from Thermal Emission Imaging System (THEMIS) thermal infrared images. Average grain size decreases with radial distance from pit rims – consistent with pit-derived ejecta but not expected for collapse models. I present a melt-contact model that might enable a delayed explosion, in which a central uplift brings ice-bearing substrate into contact with impact melt to generate steam explosions and excavate central pits during the impact modification stage. / Dissertation/Thesis / Doctoral Dissertation Geological Sciences 2016

La lune en Étrurie / La luna in Etruria / The Etruscan moon

Bettinelli, Michela 08 January 2015 (has links)
Le thème que nous avons choisi pour notre travail de doctorat nous a amenée à mener une enquête minutieuse et détaillée dans une grande variété de sources:épigraphiques, littéraires, archéologiques. A côté des sources textuelles, les données iconographiques ont joué un rôle important, et sont sans doute celles qui permettent de se faire le mieux une idée de la place et du rôle de la Lune (Tiu) dans la culture étrusque. Dans le répertoire figuré étrusque, elle apparaît souvent comme une étoile, sans jouer un rôle direct dans les scènes représentées, mais cette fonction, limitée, au niveau de l’image n’exclut évidemment pas qu’elle ait pu par ailleurs, intervenir au niveau du culte. Il paraît a priori légitime de penser qu’elle ait pu avoir dans le monde étrusque un rôle comparable à celui du Soleil (Usil), même si les données concernant le soleil sont nettement plus nombreuses et ont par conséquent suscité une bibliographie plus abondante. La répartition des deux moitiés du foie de Plaisance entre Usil et Tiu suffit à montre que la lune et le soleil avaient, dans leur dimension astrale, une fonction comparable et complémentaire. On peut donc conclure que les Etrusques n’ont pas vraiment ressenti la nécessité d'une personnification de la lune, pour laquelle les arts figurés, n’avaient rien à leur fournir.On peut donc dire que la personnification de la Lune chez les Etrusques a échoué : l’astre est resté presque toujours confiné dans son rôle d’élément du paysage céleste:quant à l’existence de formes institutionnalisées du culte de la lune, indépendamment d’une «théologie» de sa personnification, les résultats sont équivoques et ne permettent pas de la garantir absolument. / The purpose of this study is to investigate whether it is possible to identify a lunar deity in Etruria.The attributes associated with the moon, in the classical sources, describe the astral nature and its influence on life and on human events. Its manifestations in the sky are often linked to both the measurement of time as well as activities of divination. The aim of the research is to identificate aspects of the cult associated with the word TIU, which means Moon: they are therefore excluded all the processes of "transfer" to other divine figures of some peculiarities of the greek Moon goddess.The approaches used in this study must converge to build a framework that shows the existence of an anthropomorphism or personification of the moon in Etruscan culture. There is “a lot of” moon in Etruria, but what it lacks is its personification. It 'obvious deficiency in anthropomorphism: although Tiu is a fine example of persistence in the historical period of the original notion of the divinity of nature, not very well determined from the iconic point of view. And the weakness of this process, belongs from Greece.The reasons for this lability, we can find elsewhere: Selene, perhaps too weak figure in archaic Greece, acquires consistency in the Hellenistic period, but when the process of anthropomorphism have already been already completed. The conclusion of this study is still positive. The case of the moon is also very instructive in its meanings / negative evidence because it makes us really understand how it worked this interesting and complex operation that brings in the Orientalizing and High archaism to the anthropomorphism of the Etruscan pantheon.

Safe Harbor: An Exploration in Lunar Habitation

Gahres, Cameron James 31 October 2018 (has links)
This thesis posits the creation of a lunar settlement, examining the practical and theoretical challenges of urban design in a space environment. Analysis of the lunar environment aided by data and imagery from the Lunar Reconnaissance Orbiter allows the project to narrow focus on site selection while simultaneously capturing the bizarre and beautiful landscape. Intensive site study becomes the framework of a uniquely tailored, imaginative design emphasizing an urban fabric that is sensitive to astrological presences through passive and reactive design. / Master of Science / Whether it be through accident, conquest, or expedition, humanity has long held an innate desire to root itself in new environments that challenge us. The sky has proven to be no limit, the 20th century has shown that the exploration and colonization of space is inevitable. The question is where will we begin the first colony in space and what form will it take? This thesis posits the creation of a lunar settlement, examining the practical and theoretical challenges of urban design in a space environment. Site selection is crucial with the birth of any new city or civilization. Much like settlers of the past, a thorough understanding of constraints and strategic positioning is necessary to ensure the growth and survival of a colony. The accumulative site knowledge presented with this thesis is the framework of a uniquely tailored design to sustain long-term inhabitance on the moon. While this project can make no bold claims to predict the intentions of future colonists, it does serve to create an imaginative urban form to begin this journey, derived from grounded research and intensive site study. This thesis adds new perspectives beyond conventional engineered plans, to explore the potential of an immersive, reactive urban fabric with sensitivity to astrological presences. Urban design recommendations are made to enhance day to day livability in space, offer a sense of time and place, foster meaningful interaction among colonists, and consider growth beyond the initial settlement. While such a colony will undoubtedly serve as the staging area for the next steps in space exploration, it foremost will be a testament to what we as a people choose to collectively bring with us to the moon.
