By reading food television as a cultural text, through which the nation is narrated and envisioned, this dissertation examines the evolution of Korean food television and its articulation of Koreanness in contemporary globalization. Theoretically, I suggests understanding the nation as a discourse or a regime of truth from the Foucauldian perspective. In order to bring Foucault’s relativistic notion of truth into play, this dissertation employs Fairclough’s three-dimensional approach for critical discourse analysis (CDA). Through this multi-dimensional approach, I aimed to conduct a thick description of Korean food television’s discursive practice with regard to national cuisine and the Korean nation. My historical analysis of food television shows that an increased awareness of cultural others enhances a struggle for nation-ness. By unveiling the “Janus-faced” characteristic of the nation, which is constructed both against and through differences, this dissertation identifies the inextricable relationship between the nation and globalization, and the hierarchical integration processes inherent in cultural hybridization. Moreover, this research project reveals how the nation-state actively appropriates the banality of food and is involved in the production practices of the television industry in order to produce and disseminate hegemonic discourses on the nation, and to keep nationhood near the surface of everyday life. Through an investigation of the interplay between television texts and social conditions, my dissertation also explicates the socially-constructed and the socially-constitutive nature of media discourse, and enriches the discussion regarding the production cultures of the global television industries. / Media & Communication

: La théorie géométrique des invariants constitue un domaine central de la géométrie algébrique d'aujourd'hui : développée par Mumford au début des années soixante, elle a conduit à des progrès considérables dans l'étude des variétés projectives, notamment par la construction d'espaces de modules. Dans les vingt dernières années des interactions entre la théorie géométrique des invariants et la géométrie arithmétique -- plus précisément la théorie des hauteurs et la géométrie d'Arakelov -- ont été étudiés par divers auteurs (Burnol, Bost, Zhang, Soulé, Gasbarri, Chen). Dans cette thèse nous nous proposons d'un côté d'étudier de manière systématique la théorie géométrique des invariants dans le cadre de la géométrique d'Arakelov ; de l'autre de montrer que ces résultats permettent une nouvelle approche géométrique (distincte aussi de la méthode des pentes développée par Bost) aux résultats d'approximation diophantienne, tels que le Théorème de Roth et ses généralisations par Lang, Wirsing et Vojta. / Geometric invariant theory is a central subject in nowadays' algebraic geometry : developed by Mumford in the early sixties, it enhanced the knowledge of projective varieties through the construction of moduli spaces. During the last twenty years, interactions between geometric invariant theory and arithmetic geometric --- more precisely, height theory and Arakelov geometry --- have been exploited by several authors (Burnol, Bost, Zhang, Soulé, Gasbarri, Chen). In this thesis we firstly study in a systematic way how geometric invariant theory fits in the framework of Arakelov geometry; then we show that these results give a new geometric approach to questions in diophantine approximation, proving Roth's Theorem and its recent generalizations by Lang, Wirsing and Vojta.

Master of Science / Department of Geology / Matthew Totten / Due to their high resolution and established success rates, 3D seismic surveys have become one of the most important tools in many hydrocarbon exploration programs. Basic interpretation of seismic reflectors alone, however, may result in inaccurate predictions of subsurface geology. Historically, seismic attributes have played a particularly important role in the characterization of the lithological and petrophysical properties of hydrocarbon reservoirs in Kansas channel fill lithofacies. Integration of an analysis based on post-stack seismic attributes may drastically reduce the chances of drilling in unsuitable locations. Previous theses have focused on establishing a suitable 3D seismic attribute analysis workflow for use in the determination of hydrocarbon production potential in areas of Ness County, Kansas, USA (Abbas, 2009; Phillip, 2011). By applying a similar workflow in the analysis of additional 3D seismic and well log data obtained from a nearby area in Ness County, and comparing those results to existing borehole and production data, this study seeks to test the hypothesis that seismic attribute analysis is a crucial component in the delineation of heterogeneous reservoir stratigraphy in Kansas lithologies. Time-structure maps, in addition to time slices of several 3D seismic attributes including amplitude attenuation, acoustic impedance, and event continuity all seem to indicate that five previously drilled dry wells within the study area were outside the boundary of a meandering, Cherokee sandstone body of potential reservoir quality. Additionally, comparisons of the results of this research to previous studies conducted in Ness County have provided an opportunity to assess, and potentially contribute to, paleodepositional interpretations made through the utilization of a similar workflow (Raef et al., in press). The results of this study seem to support a broadly NE-SW trending meandering channel system, which is in agreement with the interpretations of Raef et al., and the findings of Ramaker (2009).

The current study set out to explore the affect and significance of differing parental conditions on the experiences commonly reported by young carers. Previous studies on young caring have reflected on the impacts of caring for parents with particular `types' of conditions (normally physical disability or mental health problems) or a specific diagnosis. However, these have not contrasted or discriminated young carers' experiences according to different parental conditions. To address this gap in knowledge, the current study considered the experiences of young carers supporting parents with different `types' of conditions, namely physical disability, mental health problems and substance misuse. The participants discussed the impact of caring on a range of areas such as their education, social life, health, spatial transitions, relationships and role reversals. Additionally, definitional issues were considered. This included young carers own understanding and subscription to the term `young carer' and the significance of this to their identification. In terms of methodology, the study was firmly grounded within the qualitative domain and influenced by a constructive-interpretive paradigm, specifically symbolic interactionism. Within this, the grounded theory approach was used insofar as it provided a method to conduct the study. A range of data-collection techniques were employed. Semi-structured interviewing was the principal method used, with additional data gathered through a self-esteem tool, observations and diaries. The sample consisted of 30 young carers. The results showed firstly that the participants did not necessarily comprehend the term `young carer' or apply it to their own caring roles at home. Arguably, this contributed to their `hidden-ness' (i. e. invisibility) and as a result their needs were overlooked. The need for a new definition which embraces their understandings, together with appropriate awareness-raising programmes within schools and for key social care and health professionals was evidenced and called for. Secondly, whilst the participants shared common experiences regardless of the nature of the parental condition, other issues reported were specific to particular situations. Those most adversely affected were caring in the contexts of parental substance misuse or parental mental health problems. Such young carers were dually disadvantaged, as they experienced the most extreme difficulties, yet their caring roles and needs were least likely to be addressed. The experiential differences reported by young carers in different caring contexts have important practice implications. Nevertheless, the extent to which the experiences reported could be wholly attributed to the caring role, rather than other structural and socio-economic factors was questionable.

Robert Louis Stevenson s The Strange Case of Dr Jekyll and Mr Hyde (1886) is the starting point for my practice-led research project. Stevenson's Victorian novella enables me to identify core themes which are pertinent to a discussion of the construction of contemporary identities in Korean youth culture. These identities are exemplified in the creation of avatars the virtual characters of animated online games such as massively multiplayer online role-playing games (MMORPGs). My animation practice is developed by addressing how Jekyll and Hyde provides useful critical and creative tools, such as gothic imagery and detective thrillers, for looking at the double . This concept is used to investigate the case of a young Korean boy, addicted to online gaming, who committed violent acts. My animated drama-documentary draws on research into the real and virtual Korean worlds and employs a visual ethnographic methodology to test my research question: in what ways can the construction of 'identity' (based on concepts drawn from 'Jekyll and Hyde') be identified in contemporary 'virtual' media (i.e. 'MMORPGs'/the 'animated' documentary), and how does this facilitate an address of the specific case of 'Korea' and 'Korean-ness'? The thesis is structured into five chapters: The Idea of Dr Jekyll and Mr Hyde, Theorising Identities in a Korean Context, Theorising Visual Ethnography, Theorising Animated Drama-Documentary, and A Film Practice as Animated Drama-Documentary in Visual Ethnography. Evidence of the research process and findings is located in a series of appendices. Theories about the construction of identity are discussed from three different perspectives: sociology, psychoanalysis and bio-culturalism. In my film practice, I look for the connection between the anxious self and Korean social issues, such as modernisation and the 1997 IMF economic crisis, to account for Korean youth s identity formation through online gaming. My research shows that many South Korean MMORPG users construct identity within contemporary virtual media and that this contributes to a very complex Korean-ness amongst Korean youth. Online gaming has both positive and negative consequences. Immersion in the virtual world can lead to addiction and to the violence which is at the core of my film narrative. It can also result in close online friendships, offering kinship not available in many broken families, or families inhibited in their communication by social roles and expectations, or the effect of economic failure and loss. My practice criticises young Korean people's narrow and limited social environment and proves that they desire liberal expression and decision-making for themselves, which can be experienced through the embodiment of animated avatars in MMORPGs. Hence, the online Hyde , though assumed to be a negative or destructive force, is actually a vehicle for varied and numerous social identities for youth culture preferable to those available in real Korean society. The research mounts a critique of the meaning of the online Hyde , not as a misrepresentative and negative representation of Korean-ness, but as a revelation of its contemporary meaning which can be articulated though animation, a tool which has applications within visual ethnography.

Master of Science / Department of Geology / Abdelmoneam Raef / This research presents a workflow integrating several post-stack seismic attributes to assist in understanding the development history of Weirman Field, Ness County, KS. This study contributes to shaping future drilling plans by establishing a workflow combining analysis of seismic attributes and well cuttings to locate a channel fill zone of better reservoir quality, and to highlight reservoir boundaries due to compartmentalization. In this study, I have successfully outlined a fluvial channel, which is expected to be significantly different in terms of petrophysical properties. The Pennsylvanian aged Cherokee sandstones that potentially comprise channel fill lithofacies, in this study, have been linked to oil production throughout the state of Kansas. It is important to understand channel sandstones when evaluating drilling prospects, because of their potential as an oil reservoir and unpredictable shapes and locations. Since their introduction in the 1970s, seismic attributes have become an essential part of lithological and petrophysical characterization of hydrocarbon reservoirs. Seismic attributes can correlate to and help reveal certain subsurface characteristics and specific geobodies that cannot be distinguished otherwise. Extracting and analyzing acoustic impedance, root-mean-square amplitude and amplitude attenuation, guided by a time window focused on the top of the Mississippian formation, resulted in an understanding of the key seismic channel-facies framework and helped to explain some of the disappointing drilling results at Weirman Field. To form a better understanding of these seismic attributes, this study combined certain attributes and overlayed them in partially transparent states in order to summarize and better visualize the resulting data. A preliminary study of spectral decomposition, which was introduced in the late 1990s, was preformed, and a more in-depth study of this multi-resolution attribute is recommended for future study of this particular field. This study also recommends integrating the revealed compartmentalization boundary and the seismic channel-facies framework in future drilling plans of Weirman Field.

Following critical/post-structural perspectives in conducting ethnographic research on the political dimension of language learning, this study examines language learners’ identity and investment in a post-secondary Korean language classroom in Canada. First, this study explores the ways in which Korean-ness is produced through the curriculum, how an instructor’s linguistic and teaching practices in the Korean language classroom function to include some students and exclude others, and how the students on the periphery cope with their marginalization. I argue that peripheral students’ coping strategies are strongly tied to their investment into certain aspects of Korean language and culture, as well as their desire to gain symbolic resources in the Korean language. Second, my study examines the ways in which Korean heritage language learners (re)negotiate their hyphenated Korean Canadian identities by looking at three different discourse sites - Korean home, Korean church, and Canadian schools - and how their hyphenated identities are connected with their investment in maintaining their heritage language. The data for this study includes classroom observations, semi-structured interviews, bi-weekly written journals and focus group interviews. By adopting critical discourse analysis (CDA) as a means of analyzing the data, this study shows that language learners’ race, ethnicity and gender are salient parts of their identities, and thus impact their learning experiences to varying degrees and levels. My research findings also suggest that the ethnic identity capital that the heritage language learners embrace in relation to their perceptions of their native speech community as well as its status, is intertwined with the maintenance of their heritage language. Pedagogical implications from this study enable educators to equally empower students from diverse backgrounds, and help them to be sensitive to the relations between ideologies and power in the language classroom. Central to these pedagogical implications is that it is the role of the teacher to adequately capitalize on the multilingual and multicultural practices that each student brings to the language classroom, and to identify the social and cultural voices present in the class.
