A drag study was conducted on an oblate ellipsoid body in the Virginia Tech Stability Wind Tunnel. Two-dimensional wake surveys were taken with a seven-hole probe and an integral momentum method was applied to the results to calculate the drag on the body. Several different model configurations were tested; these included the model oriented at a 0° and 10° angle of attack with respect to the oncoming flow. For both angles, the model was tested with and without flow trip strips. At the 0° angle of attack orientation, data were taken at a speed of 44 m/s. Data with the model at a 10° angle of attack were taken at 44 m/s and 16 m/s. The high speed flow corresponded to a length-based Reynolds number of about 4.3 million; the low speed flow gave a Reynolds number of about 1.6 million. The results indicated that the length-squared drag coefficients ranged from around 0.0026 for the 0° angle of attack test cases and 0.0035 for the 10° angle of attack test cases. The 10° angle of attack cases had higher drag due to the increase in the frontal profile area of the model and the addition of induced drag. The flow trip strips appeared to have a tiny effect on the drag; a slight increase in drag coefficient was seen by their application but it was not outside of the uncertainty in the calculation. At the lower speed, uncertainties in the calculation were so high that the drag results could not be considered with much confidence, but the drag coefficient did decrease from the higher Reynolds number cases. Uncertainty in the drag calculations derived primarily from spatial fluctuations of the mean velocity and total pressure in the wake profile; uncertainty was estimated to be about 16% or less for the 44 m/s test cases. / Master of Science

In the tradition of the Zen school, all of the monks are required to study what are called the "seven books of Zen. These books are chosen from the old Zen masters' collections, but the "seven books" are different according to each of the schools of Zen. Therefore, it is not possible to say which are "the seven books," but Lin-chi Lu is always listed as the first one of them in every school of Zen.

Bakgrund och problem: Fenomenet fast fashion erbjuder inte minst mode med låg prisbild för den stora massan samt nyheter varje vecka, utan bidrar även till massproduktion och masskonsumtion. Miljömässig skada sker under alla steg av en mode- och textil försörjningskedja, där expansionen av både produktion och konsumtion bidrar till ökad miljöpåverkan. I linje med den miljömässiga problematiken går det även att ifrågasätta det sociala ansvaret i form av billig produktion i utvecklingsländer. Hållbarhetsarbetet hos företag grundas alltsomoftast i en CSR-strategi med utgångspunkt i Triple Bottom Line där sociala-, ekonomiska- och miljömässiga aspekter agerar som grundpelare. Dubbla budskap uppstår när ett fast fashion-företag påstår sig vara ett hållbart företag eller arbeta med hållbarhetsfrågor när de samtidigt bidrar och uppmanar konsumenter till att konsumera mer. I och med den rådande “klimat-eran” har CSR i många fall omvandlats till ett marknadsföringsverktyg som syftar till att förbättra företagets varumärkesbild istället för att användas till dess faktiska syfte. Grön marknadsföring används för att differentiera sig på marknaden, och då “grönt” säljer, skapas utrymme för företagen att så kallat “tvätta sina produkter gröna”, även kallat greenwashing. Syfte: Studiens syfte är att jämföra hållbarhetsrapportering och hållbarhetsarbete hos fyra svenska fast fashion-företag, samt undersöka i vilken utsträckning eventuell greenwashing kan förekomma i samband med CSR-arbetet. Avsikten är att öka förståelsen för fast fashion som princip i relation till hållbarhetsarbetet samt bidra med ett nytänkande perspektiv och uppmana till ett mer kritiskt förhållningssätt gällande hållbarhetsarbete och klädkonsumtion. Metod: Studien bygger på en kvalitativ innehållsanalys där hållbarhetsrapporter har studerats hos fyra svenska fast fashion-företag rörande åren 2012, 2015 och 2018. Datainsamlingen har utgått ifrån teman och frågeställningar som har sin förankring i den teoretiska referensramen. Resultat och slutsats: Samtliga av de studerade företagen hållbarhetsrapporterar på olika vis och i olika utsträckning men innehållet är likartat. Samtidigt appliceras de tre grundpelarna i olika grad och tar olika stor plats i respektive företag. Utifrån studiens resultat kan det konstateras att greenwashing förekommer i hållbarhetsrapporteringen, däremot går det inte att säkerställa huruvida företagen i sin helhet kan klassas som greenwashing-företag. Vidare krävs det att fast fashion-företag har ett mer kritiskt förhållningssätt till hur affärsmodellen som sådan uppmanar till massproduktion, och vidare masskonsumtion, oavsett om klädesplagget är märkt med en grön etikett. / Background: The phenomena of fast fashion provides, not least, cheap fashion for everyone with news every week, but contributes to mass production as well as mass consumption. Every step of the fashion- and textile supply chain causes damage to the environment, where the expansion of both production and consumption contributes to increased impact on the environment. In accordance with environmental problems one can question the social responsibility in terms of cheap production in developing countries. The work of sustainability is oftentimes based on a CSR strategy with focus on the Triple Bottom Line, where social-, economical- and environmental aspects act as keystones. It occurs a double message when a fast fashion company claims to be a sustainable company or work with sustainability questions, when they at the same time contributes and urges consumers to consume even more. Due to the current “climate era”, CSR has in many cases turned into a marketing tool aimed to enhance the brand image of the company, instead of being used for its actual purpose. Green marketing is being used in order for the company to differentiate itself on the market, since “green” sells it creates an opportunity for companies to “wash their products green”, also known as greenwashing. Aim: The aim of the study is to compare the reporting and work of sustainability among four Swedish fast fashion companies, and investigate to what extent greenwashing may occur in connection with CSR. The intention is to increase the understanding for the principle of fast fashion in relation to sustainability as well as contribute with a critical rethinking perspective regarding the work of sustainability and consumption of fashion. Methodology: The study is based on a qualitative content analysis where sustainability reports from four Swedish fast fashion companies have been studied, regarding the years of 2012, 2015 and 2018. The data collection derives from themes and questions which are anchored from the theoretical framework. The following essay is written in Swedish. Findings and conclusion: All of the studied companies report their sustainability in different ways and extent but with similar content. The three keystones are at the same time applied in varied degrees and takes place in a varied extent among the companies. The result shows that greenwashing occurs in the reports, however it can’t be stated whether the companies can be classified as greenwashing-firms or not. Furthermore, fast fashion companies need to have a more critical approach towards the business model as such, which urges to mass production and mass consumption regardless if the garment is marked with a green label.

Diese Dissertation beschäftigt sich mit einer systematischen Organisation der epistemologischen Dimension des menschlichen Wissens in Bezug auf Perspektiven und Methoden. Insbesondere wird untersucht inwieweit das bekannte Organisationsprinzip der integrativen Ebenen, das eine Hierarchie zunehmender Komplexität und Integration beschreibt, geeignet ist für eine grundlegende Klassifikation von Perspektiven bzw. epistemischen Bezugsrahmen. Die zentrale These dieser Dissertation geht davon aus, dass eine angemessene Analyse solcher epistemischen Kontexte in der Lage sein sollte, unterschiedliche oder gar konfligierende Bezugsrahmen anhand von kontextübergreifenden Standards und Kriterien vergleichen und bewerten zu können. Diese Aufgabe erfordert theoretische und methodologische Grundlagen, welche die Beschränkungen eines radikalen Kontextualismus vermeiden, insbesondere die ihm innewohnende Gefahr einer Fragmentierung des Wissens aufgrund der angeblichen Inkommensurabilität epistemischer Kontexte. Basierend auf Jürgen Habermas‘ Theorie des kommunikativen Handelns und seiner Methodologie des hermeneutischen Rekonstruktionismus, wird argumentiert, dass epistemischer Pluralismus nicht zwangsläufig zu epistemischem Relativismus führen muss und dass eine systematische Organisation der Perspektivenvielfalt von bereits existierenden Modellen zur kognitiven Entwicklung profitieren kann, wie sie etwa in der Psychologie oder den Sozial- und Kulturwissenschaften rekonstruiert werden. Der vorgestellte Ansatz versteht sich als ein Beitrag zur multi-perspektivischen Wissensorganisation, der sowohl neue analytische Werkzeuge für kulturvergleichende Betrachtungen von Wissensorganisationssystemen bereitstellt als auch neue Organisationsprinzipien vorstellt für eine Kontexterschließung, die dazu beitragen kann die Ausdrucksstärke bereits vorhandener Dokumentationssprachen zu erhöhen. Zudem enthält der Anhang eine umfangreiche Zusammenstellung von Modellen integrativer Wissensebenen. / This dissertation is concerned with a systematic organization of the epistemological dimension of human knowledge in terms of viewpoints and methods. In particular, it will be explored to what extent the well-known organizing principle of integrative levels that presents a developmental hierarchy of complexity and integration can be applied for a basic classification of viewpoints or epistemic outlooks. The central thesis pursued in this investigation is that an adequate analysis of such epistemic contexts requires tools that allow to compare and evaluate divergent or even conflicting frames of reference according to context-transcending standards and criteria. This task demands a theoretical and methodological foundation that avoids the limitation of radical contextualism and its inherent threat of a fragmentation of knowledge due to the alleged incommensurability of the underlying frames of reference. Based on Jürgen Habermas’s Theory of Communicative Action and his methodology of hermeneutic reconstructionism, it will be argued that epistemic pluralism does not necessarily imply epistemic relativism and that a systematic organization of the multiplicity of perspectives can benefit from already existing models of cognitive development as reconstructed in research fields like psychology, social sciences, and humanities. The proposed cognitive-developmental approach to knowledge organization aims to contribute to a multi-perspective knowledge organization by offering both analytical tools for cross-cultural comparisons of knowledge organization systems (e.g., Seven Epitomes and Dewey Decimal Classification) and organizing principles for context representation that help to improve the expressiveness of existing documentary languages (e.g., Integrative Levels Classification). Additionally, the appendix includes an extensive compilation of conceptions and models of Integrative Levels of Knowing from a broad multidisciplinary field.

The substantial growth of online education has increased the demand for faculty who possess online teaching skills. Many institutions of higher learning offer training programs to teach faculty ways to facilitate online learning. However, the literature on online educations lacked studies demonstrating how those who complete training programs apply their newly acquired knowledge and skills. The purpose of this study was to investigate how online faculty apply the training principles and strategies learned in an online faculty-training program and how students perceive teaching effectiveness. Using a case study approach and collecting and analyzing quantitative and qualitative data determined the: (a) frequency with which faculty applied effective teaching practices learned in an online education training program; (b) barriers to using effective teaching practices in online teaching after completion of an online faculty-training program; and (c) perceptions of online students concerning faculty teaching effectiveness. The researcher used the Instructional Practices Inventory (IPI) to collect information from faculty concerning their online teaching strategies, including frequency and ease of use and proficiency of application. The researcher employed the Student Evaluation of Online Teaching Effectiveness survey (SEOTE) to determine student perception of teaching effectiveness. Data included follow-up faculty interviews, the IPI, and the SEOTE responses to create an in-depth investigation of the application of the strategies learned in the online faculty-training program. The IPI faculty survey identified the frequency of use, the ease of use, and level of proficiency of instructional strategies using the Seven Principles of Good Practice. Faculty tended to use principles that related to the online course they taught and identified time constraints as a major barrier to incorporating some of the instructional strategies. Means for instructional strategies were generally higher on ease of use and level of proficiency than they were on frequency of use. Follow-up faculty telephone interview confirmed this finding. The SEOTE results determined student perception of faculty use of the Seven Principles of Good Practice. Principle 3, active learning, ranked highest and Principle 2, cooperation among students, ranked lowest. Due to the small sample size, the finding of this study should not be generalized to other institutions.

In 1930, A.Y. Jackson and Lawren S. Harris travelled to the Arctic Archipelago as members of Canada’s Eastern Arctic Patrol. The collaborative venture between the Department of the Interior and the noted Group of Seven artists, which followed Jackson’s 1927 voyage aboard the government patrol, was part of a mutual aim to generate popular interest in the Canadian North through art. This thesis examines the underlying political context of both the 1927 and 1930 collaborative efforts. It examines the government patrols in connection with the promotion of Jackson’s and Harris’s Arctic works as part of a larger process of advancing the Arctic as a Canadian possession during a period of increased foreign interest in the region. Drawing on primary source material as well as various print media reports and exhibition reviews, this study provides insight into how the contemporary framing of Jackson’s and Harris’s Arctic sketches and paintings from the government-supported expeditions—the ways in which the works were discussed and understood—contributed not only to the “imagining” of the Arctic as a Canadian possession, but also to the dissemination of Canadian sovereignty efforts in the North. / Thesis (Master, Art History) -- Queen's University, 2012-12-05 15:24:52.546
