Voice is an inconstant yet constantly performative material; it is our internally-housed, liminal technology. ‘Processes of voice’ is the term I develop throughout the text of this thesis to articulate materialities of voice and methods of address within processes of practice in artists’ moving image that ‘give voice’ to material and non-material forms. I interrogate this in relation to key concepts in Philosophy of Mind to address the complex ways in which bodily skills and action inform perception and thought to explore an account of perception and process in relation to voice. I examine the liminal, inconstant, and uncertain in subjective experience, and the ways in which this is extended into the social through a politics of embodied practice harnessed in moving images. I make a case for the uncertain I-voice, which engages the fully embodied and openly subjective, to challenge established narratives and conventions of address, and the power and knowledge dynamics that structure them. I come to focus on the uncertain acousmatic I-voice in moving image, which through its presentness, intimacy and acknowledgement of uncertainty relinquishes the acousmêtre’s threat of control to share a liminal territory of destabilized authority with the viewer. This is also explored in and through my own moving image work, A Desire For Organic Order (2015), a single screen video, which contributes to the overall thesis.

<p>Examensarbetet har haft som syfte att utifrån dagens montering ta fram ett förslag på hur ett</p><p>optimalt monteringssystem kan se ut med avseende på effektivitet och flexibilitet på befintlig</p><p>yta.</p><p>En beskrivning av nuläget har genomförts med hjälp av observationer och intervjuer. Efter att</p><p>dagsläget analyserats har ett flertal förslag tagits fram, dessa har sedan utvärderats mellan</p><p>författarna. För att nå en slutgiltig lösning har utvärdering skett med handledaren på Moving.</p><p>För att få inblick i olika monteringssystem har författarna utfört benchmarking inom olika</p><p>branscher.

From efficient market theory we know that there is no such a thing as a free lunch. If you want higher returns then you also have to take on higher risk. The critical question technical analysis has to answer therefore becomes, does technical analysis (TA) provide an investor with an edge in the stock market? To answer this question empirically data was investigated for the Standard and Poor’s-500 Index for a twenty years time period from 1986 to 2006. Two different portfolios were constructed. The portfolios were named Hugin with a high time resolution a Munin with a lower time resolution. A simple 30 period MA cross strategy with optimized stop-losses were tested on the two portfolios. The stop-losses were optimized on the first ten years 1986-1996 in order to make the backtesting more realistic. The conclusion was that neither Hugin nor did Munin produce abnormal returns without the optimized stop losses. When the stop losses were optimized, Hugin but not Munin provided an investor with slightly better return than a long position. However Hugin’s returns were highly sensitive to the assumed level of price slippage and transaction costs. The conclusion to be drawn is therefore that investing based only on a simple 30 periods moving average crossover investment strategy seams not to be the best way to manage hard-earned money.

This dissertation analyzes the effect of smaller classes on student performance using student-level test score data from the state of Texas, focusing on three specific issues: heterogeneity in the returns to smaller classes across a score distribution of students, the relationship between class size and students' moving decisions, and the connection between smaller classes and schools' class division procedures. I first examine evidence of heterogeneity in the returns to class size reductions across a score distribution of students. I divide students into decile groups based on their previous year test scores, and I estimate the returns to smaller classes for each of the deciles. The empirical evidence supports the hypothesis that there are significant differences in students' responses to class size, based on their previous test scores. I then model the class size effect simultaneously with students' decisions to switch schools, which is important because movers compose a substantial fraction of the dataset, and because class size effects vary between movers and nonmovers. Recognizing that students move for different reasons, only some of which are school-related, I present a two-type moving model in which students are categorized as endogenous movers or exogenous movers. I estimate the model estimated using maximum likelihood. The results reveal key biases in traditional estimates of the moving effect and suggest significant differences in the class size effect across mover types. I also explore the class size effect in conjunction with schools' decisions to sort students into different classes. Using student-level data in which students are linked to specific classes, I disentangle the class size effect from the sorting effect. Including a variable indicating the sorting index of a school decreases the magnitude and significance of the class size effect. I also examine different types of sorting. The findings suggest that sorting students into more homogeneous groups is beneficial for both high and low scoring students.
