Studiens övergripande syfte är att fördjupa kunskaper om och söka nya perspektiv på estetiska lärprocesser i relation till demokrati- och värdegrundsfrågor. Den teoretiska ansatsen hämtas från poststrukturalistisk teoribildning med förgreningar inom genusteori. Studien är strukturerad i tre delar inom vilken den första utgörs av en samläsning mellan kunskapsområdet scenkonstnärlig teori/praktik och pedagogisk teori/praktik. Dessa diskurser karaktäriseras av ifrågasättanden av konsten som ”god” respektive antaganden om värdeneutrala pedagogiska modeller och det ”goda” samhället som automatisk följd av bildning och fostran. Utifrån samläsningen analyseras inom studiens andra del dokumenterade utsnitt hämtade från ett projektarbete på en skola. Detta empiriska material fyller funktionen att både exemplifiera och problematisera samläsningens utfall. Den tredje delen av studien grundar sig på de tidigare delarna och avser överskrida uppdelningen mellan scenkonstnärlig respektive pedagogisk teori/praktik genom ett framskrivande av vad som inom studien benämns som diffrakterade praktiker med implosiva konsekvenser.Genom studien analyseras det risktagande som det alltid innebär att öppna upp för liksom ingå i processer av förhandling där det inte finns några givna svar samt hur dessa processer också kräver ständiga ställningstaganden utifrån den specifika kontexten. Vidare synliggörs hur processer som ifrågasätter det förgivettagna också förutsätter vissa strukturer. Studien lyfter också fram betydelsen av andra förhållningssätt till den osäkerhet, ambivalens och det motstånd som estetiska lärprocesser exempelvis genom olika positionsförflyttningar kan resultera i. På detta sätt är avsikten att värdera dessa konsekvenser som syften i sig. I en avslutande diskussion belyses studiens resultat i perspektiv av ett samhälle präglat av förändring och mångfald och därmed också relevansen av estetiska lärprocesser i en utbildningspolitisk kontext.

This thesis details the development of the radiation transport code torus for radiation hydrodynamic applications and its subsequent use in investigating problems regarding radiative feedback. The code couples Monte Carlo photoionization with grid-based hydrodynamics and has the advantage that all of the features available to a dedicated radiation transport code are at its disposal in RHD applications. I discuss the development of the code, including the hydrodynamics scheme, the adaptive mesh refinement (AMR) framework and the coupling of radiation transport with hydrodynamics. Extensive testing of the resulting code is also presented. The main application involves the study of radiatively driven implosion (RDI), a mechanism where the expanding ionized region about a massive star impacts nearby clumps, potentially triggering star formation. Firstly I investigate the way in which the radiation field is treated, isolating the relative impacts of polychromatic and diffuse field radiation on the evolution of radiation hydrodynamic RDI models. I also produce synthetic SEDs, radio, Hα and forbidden line images of the bright rimmed clouds (BRCs) resulting from the RDI models, on which I perform standard diagnostics that are used by observers to obtain the cloud conditions. I test the accuracy of the diagnostics and show that considering the pressure difference between the neutral cloud and surrounding ionized layer can be used to infer whether or not RDI is occurring. Finally I use more synthetic observations to investigate the accuracy of molecular line diagnostics and the nature of line profiles of BRCs. I show that the previously unexplained lack of dominant blue-asymmetry (a blue-asymmetry is the expected signature of a collapsing cloud) in the line profiles of BRCs can be explained by the shell of material, swept up by the expanding ionized region, that drives into the cloud. The work in this thesis combines to help resolve the difficulties in understanding radiative feedback, which is a non–linear process that happens on small astrophysical timescales, by improving numerical models and the way in which they are compared with observations.

Ce travail de thèse porte sur le simulation d’écoulements diphasiques compressibles, visqueux et conductifs, à l’aide de schémas numériques aux différences finies centrées d’ordre élevé. Pour cela, les équation utilisées sont les équations de Navier-Stokes complétées de deux équations d’advection décrivant l’interface et d’une équation permettant d’estimer la température au sein d’un liquide et d’un gaz. Elles sont résolues à l’aide de méthodes numériques conservatives précédemment développées pour l’aéroacoustique, adaptées dans la présente étude à la simulation d’écoulements diphasiques. Les choix des équations et des méthodes numériques sont validés à l’aide de divers cas test monodimensionnels proposés dans la littérature. Les résultats obtenus sont en accord avec les solutions analytiques ou de référence. Deux écoulements 2D composés de deux gaz sont ensuite considérés. Le premier cas concerne l’instabilité de Richtmyer-Meshkov qui se développe à l’interface entre de l’air et du SF6. Le second cas porte sur une bulle cylindrique remplie d’hélium ou de R22 impactée par une onde de choc plane se propageant dans l’air. Pour ces deux écoulements, une étude de convergence de maillage est effectuée et les solutions numériques sont comparables aux données expérimentales de la littérature. L’influence du nombre de Reynolds sur la déformation de l’interface de la bulle d’hélium est également montrée. Enfin, l’implosion d’une bulle d’air dans l’eau est étudiée. Dans un premier temps, l’implosion sphérique de la bulle suite à son interaction avec une onde de pression convergente est simulée. Les résultats sont en bon accord avec les solutions prédites par le modèle de Rayleigh-Plesset. L’influence de l’épaisseur initiale de l’interface et de la conductivité thermique est montrée. Dans un second temps, l’implosion non sphérique d’une bulle proche d’un mur et impactée par une onde de choc plane est considérée. La pression imposée sur le mur et la température au sein de l’écoulement sont quantifiées. Enfin, une étude de l’effet de la distance initiale entre le mur et la bulle sur l’implosion est menée. / This PhD work concerns the simulation of compressible, viscous and conductive two-phase flows, using high-order centered finite-difference schemes. The equations governing two-phase flows are the Navier-Stokes equations in conjunction with two advection equations governing the interface and one equation allowing to estimate the temperature within a liquid and a gas. These are solved using conservative numerical methods which are validated from the resolution of various 1D test cases taken from the literature. The results obtained are in good agreement with the analytical or reference solutions. Then, two 2-D flows composed of two gases are considered. The first case concerns the Richtmyer-Meshkov instability developping at the interface between air and SF6. The second case deals with a cylindrical bubble filled with helium or R22 which is hit by a plane shock wave travelling through air. For these two flows, a grid convergence study is conducted and the numerical solutions compare well with the experimental data of the literature. The effect of the Reynolds number on the deformation of the bubble interface is also shown. Finally, the collpase of an air bubble in water is studied. Firstly, the spherical collapse of the bubble due to its interaction with a spherical converging shock wave is simulated. The results are in good agreement with the solutions predicted by the Rayleigh-Plesset model. The effect of the initial interface thickness and the thermal conductivity on the collapse is investigated. Secondly, the non-spherical collapse of a bubble near a wall impacted by a plane shock wave is considered. The pressure imposed on the wall and the temperature within the flow are quantified. Finally, the influence of the initial stand-off distance between the wall and the bubble is examined.

The aim of this thesis is to study the Swedish art field during the 1980s, from the perspective of the artistic production of Lars Nilsson. During this decade he became one of the most well known young artists associated with postmodernism. The thesis is divided into three parts, where the first part examines different influences and aspects of the art of Lars Nilsson, as well as the contexts he was a part of. This is performed through a chronological as well as a categorizing presentation, based upon different exhibitions where Nilsson participated during the 1980s. In the second part the subject is the Swedish art field, and how Lars Nilsson came to be part of a a new established category of a young generation of artists, mostly born in the 1950s, who were associated with youth, postmodernism and contemporaneousness. This part also puts attention to the importance of Lars Nittve, then art critic and curator, in introducing postmodernism, as well as establishing this new categorization of artists in Sweden. The last part of the thesis studies four different group exhibitions, and how they all exemplify how "a younger generation of artists" were to be connected with notions of postmodernism and contemporaneousness through curatorial practice. Lars Nilsson participated at the thirst three of these exhibitions. This is followed with a last group exhibition, where the idea of younger artists as the most contemporary were to be questioned. The thesis ends with a summary and a discussion.

This dissertation is a theoretical study of the role of virality/virulence as a predominant technological term in the reproduction of social and cultural information in the digital age. I argue that viral media are not new phenomena, only the name is new. Media have always behaved as viruses; it is only when they become hyper-intensified in digital technology that their virulent function surfaces in language and culture. The project examines processes of self-replication and evolution undergone by various new media phenomena as they relate back to the global profusion of social networks, data centers, and cybernetic practices. Drawing from several contributions in media theory, political and social theory, and critical media studies, I argue that digital media have a hyper-intensifying effect on whatever objects, subjects, or realities they mediate or represent; thus networked societies are virulently swarmed by their own signs and images in information. Through an examination of three primary categories of digital proliferation—language, visuality, and sexuality—I situate digital culture in a framework of virulence, arguing that the digital may be best understood as an effect of cultural hyper-saturation and implosion. I argue that virulent media networking processes come to constitute a powerful cybernetic system, which renders the human subject a mere function in its global operations. Lastly, I begin to develop a political critique of cybernetics, claiming that the proliferation of information, digital media, and communicative/representational technologies in the contemporary world emerges through an intensified ideological, economic, social, cultural, and metaphysical framework of productivism. This intensification engenders a system, or series of communicational circuits, whereby all techno-subjective activities are strategically stimulated, networked, recorded, and algorithmically appropriated to strengthen and reproduce 1) a global productivist system of cybernetics; 2) The material and ideological conditions for such a system to exist and thrive; 3) limitless virtual and digital production. / Ph.

Approved for public release, distribution is unlimited / This thesis analyzes adverse demographic trends in the European Union, including sub-replacement birthrates and increasing median ages. It investigates the implications of these trends for the EU's prospects for becoming a stronger and more influential actor in international affairs. Pressures arising from population trends in and near the EU could ultimately affect national and EU cohesion, governmental effectiveness, and social stability. Absent remedial measures, social programs in some EU countries will be unsustainable due to the mounting financial burden of pensions and health care for growing elderly populations. Such financial obligations hinder funding other national programs, including modernized military capabilities. Nationalism and national identity are at issue in immigrant integration and assimilation efforts. The role of population trends with regard to the growing threat of radical Islamic fundamentalism is explored. The thesis concludes with policy recommendations that might be considered to avert the looming economic, social, and security crises that may result from these demographic trends. In short, the security and financial consequences foreshadowed by the current demographic trends of an aging, economically weaker, and socially conflicted European Union could present dramatic implications for the vital national interests of the United States. / Lieutenant, United States Navy

This thesis re-evaluates a positive reply given by the majority of existing secondary literature on the question of whether J. L. Fischer was a democrat and a theorist of democracy. On the other hand, some features of the author's work can cast doubts on his political orientation, and the existing secondary literature does not provide a clear disapproval of these doubts. The core of this thesis then lies in forging a newly designed interpretation of the author's compositional philosophy foregoing the Second World War. We are using the existential "bloody disjunction" of the author as our interpretational key with the hope that it can allow us to explain even the most difficult parts of J. L. Fischer's work constructively to the "uninformed reader". We are recognizing the specificity of this work as an author's-actor's creative expression. Therefore its internal expressional structure should not be reduced solely to the theoretical component without attention paid to the strong philosophical, artistic, and charismatic ambitions of the creator. This thesis interprets indicated components of Fischer's philosophy and his existential fight, which, even though manifested through breaches of argumentation, is at the same time giving to the compositional philosophy a whole new level of coherency.
