ABSTRACT URBAN FISSURE: RECONCEPTUALIZATION OF THE LAND WALLS WITHIN THE URBAN MILIEU OF ISTANBUL Bas B&uuml / t&uuml / ner, Funda Ph.D. Department of City and Regional Planning Supervisor: Assoc. Prof. Dr. Baykan G&uuml / nay Co-Supervisor: Assist. Prof. Dr. Namik Erkal December 2010, 306 pages The major intention of this thesis is to introduce a new concept &ndash / urban fissure- to discuss the positionality and spatiality of city walls within contemporary urban milieus. Besides being an architectural defense structure, covering a considerable amount of land in cities, city walls have always been an important urban component. Land Walls has been a unique example of city walls that have existed for 15 centuries as an untouchable object in a metropolitan city like Istanbul. After the Ottoman Conquest in 1453, Land Walls lost their major defense purpose, and became a part of civilian life. From that time until the mid-20th century they loosely marked the west edge of the city. However, in the second half of the 20th century, with the enormous expansion of Istanbul, Land Walls have remained in the middle of the city. Throughout their history, they have produced a diversity of spaces, uses and traditions. Their unusual structure, and their complex spatiality including spaces adjoining and around them have generated several challenging processes. They have raised uncertainties and sometimes problems not only in spatial terms, but also in regulations and implementations. In this respect, regarding their current positionality and spatiality, this thesis argues Land Walls and walled zone as an urban fissure which is supposed to make them legible within the urban milieu of Istanbul.

This thesis focuses on late Early Bronze Age metal objects from funeral context from the site Kalinkaya-Toptastepe, dated to the late 4th and 3rd millennium BCE. The site yielded a large number of metal objects from EBA necropolis of the southern slope of Toptastepe, offering an ideal closed assemblage for an archaeometrical analysis to reveal the metalworking technologies of an early small rural community of Central Anatolia. First archaeometrical analysis applied on these objects, however, revealed unexpectedly high amounts of Zinc, which turned out to be not an intentional alloy, but modern contamination due to the electrochemical cleaning, carried out in the 1970s. A second analysis has carried out after cleaning the metal objects with micro-sandblasting technique, to remove the artificial Zn contamination. The accumulated data provided us with important insights into the metal consumption and alloying traditions of a late EBA village community in Central Anatolia, showing the earliest conscious alloys were being applied in small hamlets of the EBA as well. It has been apparent that any pre-Iron Age metal object, revealing Zn in its chemical composition can not be considered as early brass, but clearly a result of modern, ill-advised cleaning application.

Started as an EOR technique to produce oil, injection of carbon dioxide which is essentially a greenhouse gas is becoming more and more important. Although there are a number of mathematical modeling studies, experimental studies are limited and most studies focus on injection into sandstone reservoirs as opposed to carbonate ones. This study presents the results of computerized tomography (CT) monitored laboratory experiments to characterize relevant chemical reactions associated with injection and storage of CO2 in carbonate formations. Porosity changes along the core plugs and the corresponding permeability changes are reported for varying CO2 injection rates, temperature and salt concentrations. CT monitored experiments are designed to model fast near well bore flow and slow reservoir flows. It was observed that either a permeability improvement or a permeability reduction can be obtained. The trend of change in rock properties is very case dependent because it is related to distribution of pores, brine composition and as well the thermodynamic conditions. As the salt concentration decreased the porosity and thus the permeability decrease was less pronounced. Calcite scaling is mainly influenced by orientation and horizontal flow resulted in larger calcite deposition compared to vertical flow. The duration of CO2 &ndash / rock contact and the amount of area contacted by CO2 seems to have a more pronounced effect compared to rate effect. The experiments were modeled using a multi-phase, non-isothermal commercial simulator where solution and deposition of calcite were considered by the means of chemical reactions. The calibrated model was then used to analyze field scale injections and to model the potential CO2 sequestration capacity of a hypothetical carbonate aquifer formation. It was observed that solubility and hydrodynamic storage of CO2 is larger compared to mineral trapping.

In this study, hazardous waste inventory for Turkey is developed based on wastes identified as hazardous in European Waste Catalogue and Regulation on Control of Hazardous Wastes, Annex 7 Necessity of such inventory arises from importance of acquiring information on the amount of hazardous wastes generated and on their countrywide distribution for a sound hazardous waste management system for Turkey. Hazardous waste inventory is constructed by using waste generation factors obtained from literature which are coefficients that relate production with environmental emissions. Whenever possible, direct information obtained from generators was utilized. Both absolute and minor entries are covered. It is estimated that 4,940,000 &ndash / 5,110,000 t/yr of hazardous wastes are being generated in Turkey. 1,790,000 &ndash / 2,252,000 t/yr of these are classified as absolute entries and 3,146,000 &ndash / 3,160,000 t/yr of hazardous wastes are minor entries. It is observed that highest generation occurs from mining and thermal processes which involve high amounts of minor entries. Beside these industries highest generation occurs from wood preservation. Per capita hazardous waste generation is estimated as 30 &ndash / 77 kg/capita/yr which is in accordance with per capita generation range of EU. Highest hazardous waste generation occurs from Marmara Region with 527,730 t/yr followed by Aegean (524,580 t/yr), Central Anatolia (481,820 t/yr), Black Sea Region (277,850 t/yr), Mediterranean (211,580 t/yr), Southeast Anatolia (58,290 t/yr) and Eastern Anatolia (36,520 t/yr) excluding minor entries from mining industry and thermal processes. The trends in hazardous waste generation and GDP from manufacturing industry show the same trend. Contribution of regions are in the same order both in hazardous waste generation and GDP.

The main objective of the dissertation is to apply recent advances in modern econometric analysis, namely cointegrating Vector Autoregression (VAR) and Bayesian VAR (BVAR) to a small open regional economy like Hawaii. This is accomplished in three related yet independent essays demonstrating how regional modeling and forecasting can benefit from these latest developments. The first essay concentrates on the cointegrating VAR analysis, applying it to Hawaii's premier industry-tourism. Recent research in the literature on identified cointegrating VARs emphasizes the need to rely on economic theory to impose weak exogeneity assumptions, guide the search for long-run just (over) identifying restrictions and shrink the model to the most parsimonious representation. While cointegration analysis has gradually appeared in the empirical tourism literature, the focus has been exclusively on the demand side with no use of the latest identification techniques. A complete Hawaii tourism model is developed, exploiting Hall, Henry, and Greenslade's (2002) theory-directed sequential reduction methodology. Both demand and supply factors are emphasized in identifying long-run cointegrating relationships. The second essay applies the BVAR methodology to another key sector in regional modeling-construction. This essay represents the first application of priors on linear combinations of parameters-namely, sums of coefficients and dummy initial observation priors - in a BVAR construction forecasting model. I find that including these priors does not necessarily improve forecast accuracy at medium to long horizons, especially when the series are integrated and there is more than one cointegrating relationship. The third essay extends the second essay to deal with the entire regional economy. All regional models must deal with the inavailability of expenditure data at the state and local levels. This problem typically leads researchers to use either a single highly restricted VAR, or BVAR, or a model of pseudo theory driven equations. In contrast, my third essay makes use of BVAR blocks to model proxies for the expenditure categories in a traditional macro structure. Compared with existing regional BVAR models, the current setup is more complete in accounting for both the intra-action of sectors within the region and the inter-action of the region with external drivers.

The topic of this diploma thesis is ?Physiognomically we have still been passers - by. Travelling as an intercultural experience in the work of Christoph Ransmayr?. This thesis is divided into seven basic parts. The first four chapters describe theoretical background of the thesis which is the Postmodernism, the Philosophy of the Postmodernism, the Interculturality and the Theory of Essays. The next chapter reports about the poetics of the narration and the aim of the last two parts is to analyze the books "Geständnisse eines Touristen" and "Der Weg nach Surabaya". The ambition of this diploma thesis is to research the relationship of Christoph Ransmayr to travelling and search for the influences of the travelling poetics in his two concrete books.

So called ‘video essays’ on films and cinema have gained substantial popularity on the video sharing internet site YouTube in the past years. This essay explores this relatively recent type of video production from the perspective of genre analysis in order to investigate whether a pattern of form, content and style can be identified, which would suggest the emergence of a new genre. Previous research has investigated a similar genre, the film review, by identifying its pervasive or obligatory moves or stages (Taboada, 2011; de Jong & Burgers, 2013). However, video essays seem to be a rather subjective form of communication, with a clear persuasive purpose. For this reason, linguistic elements expressing evaluation, assessment, feelings and opinions are analyzed in the following under the umbrella term for evaluative language use, that is Appraisal (White, 2015). Five video essays from different creators were chosen for the present analysis, which is focused on situational, structural, and Appraisal elements. The analysis shows that there indeed are similarities between the video essays, pertaining both to their situational context and structure, and their use of evaluative language. Several overall pervasive moves were found, which suggests that the essays follow a specific structural pattern. The evaluative language indicates an intention of persuading the viewer.

H.P. Lovecraft, em seus ensaios e cartas, nos oferece uma reflexão riquíssima sobre a narrativa de horror e como esta deve se expressar na literatura. O autor cunhou o termo Horror Cósmico para denominar sua teoria estética. Porém, mais do que ser uma teorização sobre o horror na literatura, o Horror Cósmico é uma teorização sobre como deve ser a narrativa que Lovecraft julga ser a ideal para as histórias que deseja contar. Nessa perspectiva, a análise de sua ficção, acompanhado dos conhecimentos adquiridos pela análise pormenorizada de seus ensaios e cartas sobre o tema, permitem ao leitor compreender melhor sua obra, chegando assim a uma interpretação aproximadamente correta de sua ficção. O objetivo deste trabalho, portanto, é compreender como suas teorizações se refletem em seus textos ficcionais. Os contos e respectivas transposições fílmicas selecionadas foram analisados sobre o prisma destas teorizações. Para alcançarmos esse objetivo primeiro analisamos os seus contos comparativamente com os textos não ficcionais, a fim de compreendermos a forma como o autor expressa o conceito de Horror Cósmico em sua prosa ficcional. Após a compreensão dos elementos teóricos de Lovecraft em sua ficção, analisamos as transposições fílmicas selecionadas sob esse mesmo prisma. Pesquisas bibliográficas foram realizadas com o objetivo de construir um referencial teórico para a abordagem proposta. / H.P. Lovecraft, in his essays and letters, offers the reader powerful insights into the subject of horror and how it should be expressed in literature. The author coined the term Cosmic Fear to name his aesthetic theory. However, in addition to being a theory about horror in literature, Cosmic Fear is a theory about how the ideal horror story (as Lovecraft wishes to write it) should be. From this perspective, the analysis of Lovecraft´s fiction, accompanied by the knowledge acquired through a detailed analysis of his essays and letters on the subject, allows the reader to better understand his work, thus reaching an approximately correct interpretation of his fiction. The goal of our research, therefore, is to understand how Lovecraft´s aesthetic theory works in his fiction. The short stories, novels and the filmic transpositions we selected for this research were analyzed under the prism of these theories. To achieve this goal we analyzed his fiction by comparing it first to his non-fiction in order to understand the concept of Cosmic Fear in his fiction. After understanding Cosmic Fear in Lovecraft´s fiction, we analyzed the selected filmic transpositions under the same prism. Bibliographic references were used with the purpose of building a theoretical framework for the proposed approach.
