Off the orbit : works of art for long-term space travellers : outline of a novel artistic practice

Johannsen, Kirsten January 2012 (has links)
This research combines the arts with human spaceflight. The aim of the investigation is to identify the aesthetic parameters for display in works of art on extended crewed missions. The study claims that, within the research area of human spaceflight, novel working methods should be developed that can integrate the artist into the scientific process. The extraordinary challenges of extended space exploration not only concern technical and human-bodily aspects, they will also affect the enormous psychological and psychosocial restrictions the spacefarer will face. These limitations are due to the unusual distance and the long timeframes; the future explorers will live confined and isolated within the habitat environment far away from their place of origin. In addition, the consequences of sensory deprivation caused by the high-tech indoor habitat, the emptiness of outer space, the effects of social monotony and limited contact with home will dominate their life in the extreme environment and the emotional state of the future explorer. Many cultural techniques for recreation and stress mitigation are already in use or will be tested in human spaceflight in the near future. However, in this context the implementation of works of art has not been evaluated. The production of works of art for future astronauts represents a new research area. From the artistic perspective, creativity will expand in an unusual manner. Artists will not only have to develop significant metaphors, they will also be confronted with an unknown responsibility, because the confined and isolated astronaut will become the exclusive audience and user of their works. Furthermore, works of art must follow the particular demands of verifiability, safety, and reliability. These specific conditions will give the artistic work a unique meaning which makes the work a part of the life-sustaining system. The outcome will be an experiment that combines both artistic and scientific strategies.

Endless house : models of thought for dwelling

Kiaer, Ian January 2008 (has links)
The following thesis is a 38,400 word document of a part-time PhD by project undertaken at the painting department of The Royal College of Art between October 2002 and September 2008. The purpose of this research has been to reflect on how an expansive interpretation of the architectural model operates as a mode of fragmentary thought for dwelling. I extend critical / theoretical approaches to the use of the model within my art practice, and its equivalent, 'the essay form,' in the written component of the thesis. I begin by deflning the use of the model within a speciflc work I made early in the project, and also discuss the model's ability to operate between more rigidly deflned disciplines of knowledge. I use Benjamin's notion of immanent critique to reflect on the poeticised potential of the model form to unfold information, by probing the rapport between materials and motifs, groupings and spacings and the made and the found. I also show how the process of thought through the material development of the work, informed an equivalent fragmentary approach to writing. In the four main chapters, I attend to a critical pairing four Bruegel paintings and four particular buildings to understand how both painting and building can be revealed as a thought model for dwelling. The chapters in the following order read Bruegel's Fall of Icarus in relation to Casa Malaparte, Procession to Calvary with Melnikov's Cylindical House Studio, The Tower of Babel with Kiesler's unbuilt notion of The Endless House, and flnally the two dwellings initiated by Wittgenstein with Hunters in the Snow. I conclude by returning briefly to a recent piece of my own work to consider how the model of thought for dwelling has developed within my current practice.

Photocatalytic Carbon Dioxide Reduction In Liquid Media

Ipek, Bahar 01 April 2011 (has links) (PDF)
The aim of this study is to investigate and reveal challenges in photocatalytic CO2 reduction tests performed in liquid media. Effect of test conditions in photocatalytic studies are often underestimated with an assumption of negligible mass transfer limitations in observed rate results. In this study, effect of mass transfer limitations in liquid phase photocatalytic tests was revealed with stirring rate and gas hold-up time experiments performed with Pt/TiO2 and Cu/TiO2 catalysts. In addition, apparent activation energies of 12 and 19.5 kJ/mol found with Pt/TiO2 and Cu/TiO2 catalysts respectively indicate diffusion limitations which favor back oxidation reactions resulting in low reduction yields. Photocatalytic CO2 reduction reaction is named as Artificial Photosynthesis even though present artificial system does not have sophisticated transport and membrane systems which natural systems have. Similarities and differences between artificial and natural photosynthesis are studied in order to present ideas to improve present photocatalytic rates. Kinetic and microkinetic modeling of catalytic methanol production from CO2 hydrogenation on Cu surfaces were performed in order to have an idea about kinetic limitations at photocatalytic systems. Calculations were performed at temperatures and pressures at which photocatalytic studies are conducted. The results indicated that water has an inhibitory effect on methanol formation rates and higher pressures could be implemented in photocatalytic systems for higher rates. Another implication drawn from degree of rate control calculations is that H formation step plays an important role underlying the importance of water splitting in CO2 reduction reactions.

Phytoestrogen Contents Of Selected Foods

Gultekin, Esra 01 September 2004 (has links) (PDF)
Phytoestrogens are naturally occurring chemicals of plant origin that have the ability to cause estrogenic and/or anti-estrogenic effects due to their structural similarities to the human hormone oestradiol. It has been proposed that phytoestrogens protect against a wide range of ailments, including breast and prostate cancers, cardiovascular disease, osteoporosis, and menopausal symptoms. Daidzein, biochanin A and especially genistein which has been reported to be the most biologically active dietary phytoestrogen attract great deal of interest in today&rsquo / s researches. In this study, twenty different food items, including legumes, fruits, nuts and herbs, (haricot beans, chickpeas, green lentils, red lentils, soybeans, licorice root, yarrow, dried chestnuts, prunes, raisins, currants, black cumin, dried apricots, dried parsley, dried dates, dried figs, sage (from Aegean region), sage (from Mediterranean region), grapevine leaves, gilaburu) were selected. Following an extraction procedure employing acid hydrolysis and heating / they were analysed for their daidzein, genistein and biochanin A contents using a reversed-phase C18 column with linear gradient elution on a high-performance liquid chromatography (HPLC) coupled with diode-array detector (DAD). Soybeans were found to contain high amounts of daidzein (91.36 mg/100 g) and genistein (85.57 mg/100 g). Chickpeas were found to contain much less amount of genistein (0.89 mg/100 g) compared with that of soybeans and also biochanin A (0.95 mg/100 g) which was not detected in soybeans. None of daidzein, genistein and biochanin A was detected in the remaining eighteen food items.

Revisionspaketet och kreditgivare : Bankers användning av revisionsberättelsen vid kreditgivning till börsnoterade bolag

Jakobsson, Haidi, Nilsson, Elin January 2018 (has links)
Den 31 december 2016 blev nya regler om utformningen av revisionsberättelser för börsnoterade bolag gällande. En bakgrund till implementeringen var att det fanns uppfattningar om att revisorer på ett tydligare sätt skulle redovisa det som framkommit genom revisionen i revisionsberättelsen. Externa intressenter till börsnoterade bolag skulle därigenom få tillgång till mer kvalitativ information. Till intressenter som har behov av sådan information hör kreditgivare, vilka behöver kunna bedöma bolags förmåga till återbetalning. Syftet med denna studie är att skapa förståelse för vilken påverkan de nya tilläggen i revisionsberättelsen har haft på bankers kreditgivningsprocess vid beslut om kreditgivning till börsnoterade bolag. Det har undersökts genom att utföra åtta stycken intervjuer med kreditgivare till börsnoterade bolag. Studiens resultat tyder på att revisionsberättelsen inte har ansetts utgöra ett betydelsefullt underlag varken före eller efter det att förändringen trädde i kraft. Det indikerar att de nya tilläggen inte har haft någon påverkan på bankernas beslut om kreditgivning.

Särskilt Betydelsefulla Områden : En innehållsanalys om den utökade revisionsberättelsens utvecklingsriktning för svenska börsnoterade bolag

Stenbeck, Louise, Satarova, Aidai January 2021 (has links)
The previous audit report has been considered too standardized which has led to debates about its value and relevance as it was considered to have no direct connection to the company. With the financial crisis and audit scandals as a catalyst in the early 2000s, the process to create a new audit report was initiated. This resulted in that IAASB implemented a number of new standards that would affect the form of the auditor's report but also the content in 2016. One of these new standards was ISA 701, which infer that all listed companies must communicate Key Audit Matters. The purpose of this part of the audit report is to provide stakeholders with more qualitative information about the audit and entity specific information. Discussions have taken place as to whether KAM works in practice to provide relevant information that is unique to the company and thus increase the audit report's value and relevance. Some believe that KAM will generate more entity specific information, while others express that there may be reason to assume that the new section will be a new standardized part of the new audit report.  The purpose of this study is to examine the direction of development for communication of KAM in a Swedish context. Furthermore this study aims to examine whether there is a direction of development with elements of tendencies towards a standardization of KAM. To examine the purpose of the study, a random sample of 100 companies operating in the regulated market was conducted. The audit reports have been studied with the help of an content analysis for the period 2016–2020. The study seeks support in agent theory, institutional theory but also previous research on structure and KAM in analysis of the direction of development for KAM.  The study can provide support for a direction of development that has tendencies towards standardization in the form of a uniform structure regarding its length and how many KAMs that are communicated. Nevertheless, the study can also support a direction of development with a lack of standardization regards to the communicated KAM company-specific character that has been relatively unchanged during the period. Taking into account the observations made by the study, the study cannot draw unequivocal conclusions that there is a direction of development with tendencies towards standardization of the communication of KAM for Swedish companies. / Den tidigare revisionsberättelsen har ansetts vara alltför standardiserad vilket har lett till debatter kring dess värde samt relevans då den saknar direkt anknytning till företaget. Med finanskrisen och revisionsskandaler som katalysator i början av 2000-talet initierades arbetet för att skapa en ny revisionsberättelse. Detta resulterade i att IAASB implementerade ett antal nya standarder som skulle komma att påverka revisionsberättelsens utformning men även innehåll år 2016. En av dessa nya standarder var ISA 701 som innebär att bolag som verkar på en reglerad marknad ska kommunicera Särskilt Betydelsefulla Områden (SBO). Syftet med denna del i revisionsberättelsen är att tillgodose intressenter med mer kvalitativ information om revisionen och företagsspecifik väsentlig information. Diskussioner har förts hur SBO verkar i praktiken för att tillgodose relevant information som är unik för företaget och på så sätt öka revisionsberättelsen värderelevans. Somliga anser att SBO kommer att generera mer företagsspecifik information medan andra uttrycker att det kan föreligga skäl att anta att nya avsnittet blir en ny standardiserad del i den nya revisionsberättelsen.  Syftet med denna uppsats är att undersöka utvecklingsriktningen för kommunikationen av SBO i en svensk kontext. Vidare syftar denna uppsats studera om det föreligger tendenser till att det sker en standardisering av kommunikationen av SBO. För att undersöka studiens syfte genomfördes ett slumpmässigt urval på 100 stycken bolag som verkar på den reglerade marknaden varav revisionsberättelser studerades genom en innehållsanalys för perioden 2016–2020. Studien söker stöd i agentteorin, den institutionella teorin men även tidigare forskning om struktur och SBO vid analys om SBO utvecklingsriktning.  Studien kan ge stöd för en utvecklingsriktning som har tendenser till standardisering i form av en enhetlig struktur gällande dess längd och hur många SBO som kommuniceras. Likafullt kan studien stödja en utvecklingsriktning med en avsaknad av standardisering med avseende till de kommunicerade SBO företagsspecifika karaktär som har varit relativt oförändrad under undersökningsperioden. Med beaktning till de observationer som studien frambringat kan denna studie inte dra entydiga slutsatser om det föreligger en utvecklingsriktning med tendenser till standardisering av SBO för svenska bolag.

Bilderpolitik: Michel Foucault (1926 - 1984)

Schneider, Ulrich Johannes 18 July 2014 (has links)
Michel Foucault hat Bücher geschrieben, welche die Geschichte des Denkens in Worte fassen, und er hat in Aufsätzen Bilder betrachtet, die er intensiv beschrieb, so dass sein Text vollkommen darin aufging, kaum selber den Rand überschritt, den sie als Kunstwerk besitzen. Foucaults Arbeiten über Magritte - Dies ist keine Pfeife! - und Manet - ein großes Manuskript hat er selbst vernichtet - legen Zeugnis ab von der Passion für Kunst, der Faszination für die Darstellung am Rande der Vorstellung, außerhalb der Arbeit des Historikers, eine Art Sonntagsbetrachtung. Foucaults bildbezogene Texte sind Verbeugungen eines Kenners, Übungen des Gebildeten, Räsonnements eines Philosophen - sie sind nicht Teil der historiografischen Anstrengung, Epochen auszuzirkeln und Aussagen zu archivieren.

Spiel mit Sterben

Penning, Laura 16 August 2019 (has links)
Im Rahmen der Performancekunst in Nordamerika und Europa seit 1970 lassen sich Performances ausmachen, die sich inhaltlich mit dem Sterben befassen. Die vorliegende Dissertation widmet sich der Frage, inwiefern sich die existenzielle Performancekunst als Medium zur Evokation von Sterblichkeitsbewusstsein eignet. Den Untersuchungsgegenstand bilden 19 Performances, die als existenzielle Performancekunst bezeichnet werden. Die Performer*innen zeigen ihr „Spiel mit dem Sterben“ oder laden dazu ein, bei der Auseinandersetzung mit dem Sterben mitzuspielen. Es wird analysiert, auf welche Weise sich die elf Performer*innen in existenzieller Performance mit Sterblichkeit befassen. Dabei fällt auf, dass es einerseits eine spielerische, liminoide Auseinandersetzung mit dem Thema gibt. Andererseits lassen sich existenzielle Performances ausmachen, die eine ernste, liminale Auseinandersetzung mit der Sterblichkeit aufzeigen, da sich der Künstler/die Künstlerin Schmerzen zufügt bzw. zufügen lässt oder gar in die Gefahr begibt, während der Performance zu sterben. Jene dichotomischen Aspekte, wie sie bereits der Anthropologe Victor Turner beschrieb, werden konkretisiert mit existenzieller Performancekunst in Zusammenhang gebracht und zudem auf Überlegungen der Theaterwissenschaftlerin Erika Fischer-Lichte zur Liminalität bezogen und weiterentwickelt. Im Fokus stehen somit auftretende und sich auflösende Dichotomien, sowie die Interpersonalität zwischen Performenden und Teilnehmenden. Darüber hinaus werden Primäraspekte existenzieller Performancekunst herausgearbeitet. Die Primäraspekte und die dichotomischen Aspekte werden im Hinblick auf die Evokation von Sterblichkeitsbewusstsein untersucht. Die vorliegende Dissertation reflektiert darüber hinaus Fragen der Medialität von existenzieller Performancekunst. / Within the context of performance art in North America and Europe since 1970 several performances that consider mortality can be identified. This dissertation deals with the question, whether existential performance art is suitable as medium to evoke an awareness of mortality. The research object consists of 19 performances that are designated as existential performance art. The performers show their „play with dying“ or invite to participate in the involvement with dying. It is analysed in which kind of way the eleven performer deal with mortality in existential performance art. As can be noticed, on the one hand there is a ludic and liminoid involvement with dying. On the other hand art performances can be identified that demonstrate serious and liminal involvement with dying, because of the artist`s willingness to suffer or even to run the risk of losing his or her life while performing. Those dichotomic aspects, as already described by anthropologist Victor Turner, are made concrete and brought into connection with existential performance art in this dissertation. Furthermore the dissertation refers to Erika Fischer-Lichte`s thoughts concerning liminality, but extends the ideas related to existential performance art and mortality. Oscillating dichotomies are focussed on as well as the interpersonal encounter between performer and participant. Primary aspects of existential performance art are worked out. Both dichotomic and primary aspects are examined concerning their role in evoking an awareness of mortality. Moreover this dissertation reflects on mediality of existential performance art.

Vad påverkar revisorns bedömningar av särskilt betydelsefulla områden i praktiken? : En kvantitativ studie om revisionsstandarden ISA 701

Ericsson, Mathilda, Ljungdahl, Ida January 2024 (has links)
Titel: Vad påverkar revisorns bedömningar av särskilt betydelsefulla områden i praktiken? En kvantitativ studie om revisionsstandarden ISA 701   Nivå: Examensarbete på grundnivå (kandidatexamen) i ämnet företagsekonomi    Författare: Mathilda Ericsson och Ida Ljungdahl   Handledare: Mattias Hamberg   Datum: 2024 – maj   Syfte: Utifrån ISA 701 är syftet med denna studie att undersöka hur företagsspecifika faktorer påverkar antalet särskilt betydelsefulla områden rapporterade av revisorn i revisionsberättelsen.   Metod: Med en deduktiv ansats och kvantitativ forskningsmetod har studiens hypoteser prövats genom en korrelationsmatris samt multivariata regressionsmodeller. Totalt har 2 091 observationer från svenska börsbolags årsredovisningar mellan åren 2016 och 2022 analyserats.   Resultat och slutsats: I studien finns stöd för signifikanta samband mellan antalet särskilt betydelsefulla områden och samtliga företagsspecifika faktorer som testats. Resultatet indikerar därmed att företagens agentproblem och komplexitet i viss mån styr revisorns bedömningar.    Examensarbetets bidrag: Studiens resultat tillför nya insikter kring revisorers bedömningar av särskilt betydelsefulla områden. Det kan vara relevant för standardiseringsorgan inom revision, upprättare och användare av redovisningsrapporter, samt för praktiserande revisorer.   Förslag till framtida forskning: Framtida forskning kan inkludera andra företagsspecifika faktorer och undersöka om det ger liknande resultat. Förslagsvis kan fokus ligga på relationen mellan revisor och klient. Slutligen föreslås att undersöka ISA 701 med en kvalitativ metod.    Nyckelord: ISA 701; Utvidgad revisionsberättelse; Särskilt betydelsefulla områden; Agentteori; Agentproblem / Title: What influences the auditor's assessments of Key Audit Matters in practice? A quantitative study on the auditing standard ISA 701   Level: Student thesis, final assignment for Bachelor Degree in Business Administration   Author: Mathilda Ericsson and Ida Ljungdahl   Supervisor: Mattias Hamberg   Date: 2024 – May   Aim: Based on ISA 701, the purpose of this study is to examine how company-specific factors influence the number of Key Audit Matters reported by the auditor in the auditor’s report.   Method: With a deductive approach and quantitative research method, the study's hypotheses have been tested using a correlation matrix and multivariate regression analysis. In total, 2 091 observations from Swedish listed companies' annual reports (2016-2022) were analyzed.   Results and conclusions: In the study, there is support for significant relationships between the number of Key Audit Matters and all company-specific factors tested. It indicates that the companies' agency problems and complexity govern the auditor's assessments to some extent.    Contribution of the thesis: The results provide new insights into auditors' assessments of Key Audit Matters. This information may be relevant to standard-setting bodies in auditing, preparers and users of accounting reports, and to practicing auditors.   Suggestions for future research: Future research could include other company-specific factors. One suggestion is to focus specifically on the relationship between auditor and client. Additionally, it is proposed to examine ISA 701 using a qualitative method.   Key words: ISA 701; Extended auditor’s report; Key Audit Matters; Agency theory; Agency problem
