Unconventional story-weavers and their "Ecstatic Truth": An analysis of voice-overs in documentary film

Includes bibliographical references.This dissertation takes theories of voice-over narration that are typically applied to fiction film and applies them to documentary film. It looks at issues of representation and truth values in the documentary films of Werner Herzog, John Marshall, Luis Buñuel and Karin Jurshcick. It argues that the choices filmmakers make regarding types of voice-over affect these issues and are therefore worthy of study. It argues that the unconventional story-weavers in documentaries like those of Marshall and Herzog‘s can inadvertently marginalise their subjects. It looks at Buñuel‘s Land Without Bread as an extreme example of an (intentionally) manipulative narrator. It suggests that a voice-over narrator that follows Chion‘s conceptualisation of the complete acousmêtre encourages audiences to engage on a more critical level. Finally, it argues that even a seemingly traditional narrator as seen in Jurshick‘sIt Should Have Been Nice After That can be unconventional and reveal an - ecstatic truth

Infeasible Full-Newton-Step Interior-Point Method for the Linear Complementarity Problems

In this tesis, we present a new Infeasible Interior-Point Method (IPM) for monotone Linear Complementarity Problem (LPC). The advantage of the method is that it uses full Newton-steps, thus, avoiding the calculation of the step size at each iteration. However, by suitable choice of parameters the iterates are forced to stay in the neighborhood of the central path, hence, still guaranteeing the global convergence of the method under strict feasibility assumption. The number of iterations necessary to find -approximate solution of the problem matches the best known iteration bounds for these types of methods. The preliminary implementation of the method and numerical results indicate robustness and practical validity of the method

Changes in the Internal Organizational and Administrative Practices in the Elementary School from 1945 to 1950

This study is designed to show what changes have been made in the organization and the administration of the elementary school from 1945 to 1950, as revealed in the literature and to point out possible trends, or indices of trends during this period. The expression or indices of trends is used because it is difficult to point out trends in elementary education in a five-year period. The elementary school is not perfect, but that it is constantly changing in an effort to improve, is becoming more evident in the field of elementary education. This writer believes that democratic society never remains constant; we are always developing the elementary school, which has made notable progress during the last half century. Local and world conditions have their influence upon education which cause the internal changes in content and administration of the elementary curriculum. Changes are made in education to stimulate the program of the School, so that it will meet the growing needs of the children during their developmental period

Alkyne Combustion: Experimental and Computational Studies of Formyl Radical Production

The United States consumed a total of 97.4 trillion BTUs of energy in 2016 with over 80% of that energy consumption source being fossil fuel combustion. Before a combustion reactions reaches its end products, a number of intermediate products form and may react with other abundant atmospheric species to form aerosol particles and acid rain, both of which have potentially negative impacts on both human-made structures and the natural environment. In an effort to counteract the consequences of fossil fuel combustion, scientists are interested in understanding the reaction mechanisms of hydrocarbon combustion reactions to understand which intermediate products form and how. One of the many intermediate products formed in hydrocarbon combustion reactions if the formyl radical, HCO. Discovered in 1934, HCO has since been proven to form in many hundreds of combustion reactions and plays key roles in both atmospheric and interstellar chemistry, namely as a donor of hydroxyl radicals. While alkane combustion has been studies extensively in the past, alkene and alkyne combustion has received little attention beyond the short-chain species: ethylene, propene, acetylene, and propyne. Due to remaining relatively uninvestigated, the formation of HCO during alkyne combustion reactions is focused on in this project. This thesis provides both an experimental and theoretical perspective on the reactions of atomic oxygen atoms, O(3P), with the alkynes propargyl alcohol and 3-butyn-1-ol. Preliminary experimental studies of alkyne combustion revealed strong variations in HCO absorption intensity across different alkyne species. The most dramatic difference in HCO absorption intensity was observed between the combustion of propyne and propargyl alcohol, where propargyl alcohol gave a much stronger signal for HCO than propyne. Both compounds are three carbon alkynes, with the only difference being the hydroxyl substituent on propargyl alcohol. This study attempts to explain these variations via computational investigation. Utilizing optimization QM methods, potential energy profiles are mapped out to reveal the energetics of reaction pathways that result in the formation of HCO. Isoformyl radical, HOC, is also investigated computationally in this project as it is the higher energy isomer of HCO and may isomerize to the lower energy state. The computational portion of this study reveals a higher number of HCO/HOC formation pathways for the alcohol-substituted alkynes and focused on the reactions of O(3P) + propargyl alcohol and O(3P) + 3-butyn-1-ol. The experimental portion of this study involves the detection of HCO as it forms during alkyne combustion via Cavity Ring-down Laser Absorption Spectroscopy (CRDLAS)

Curing Kinetic Analysis of Acrylate Photopolymer for Additive Manufacturing by Photo-DSC

In this research, the curing degree of an acrylate-based monomer using direct UV-assisted writing technology was characterized by differential photo calorimetry (Photo-DSC) to investigate the curing behavior. Triggered by the UV light, the duo function group monomer 1,6-Hexamethylene diacrylate (HDDA), photoinitiator 1173 and photoinhibitor exhibit a fast curing process. The exothermal photopolymerization reaction was performed in the isothermal mode in order to evaluate the different thermal effects that occurred during the photopolymerization process. The influences of both UV light intensity and exposure time were studied with single-factor analysis. The results obtained by photo-DSC also allow us to perform the kinetic study of the polymerization process: The results show that, for the reaction, the higher the UV intensity, the higher the curing degree together with faster curing speed. At the same time, the effect of the heat released during the exothermic reaction is negligible for the polymerization process. When increasing the exposure time, limited improvement of curing degree was shown, and the distribution is between 65–75%. The reaction enthalpy and related curing degree work as a function of time. The Avrami theory of phase change was introduced to describe the experimental data. The functions of a curing degree with light intensity and exposure time were achieved, respectively

Influence of Filler Content and Filler Size on the Curing Kinetics of an Epoxy Resin

In this research, the influences of filler content and filler particle size on the flow-hardening behavior were investigated by a measuring mixer. In order to more reliably assess the observed rheological behavior, isothermal differential scanning calorimetry (DSC) measurements were employed to study the curing kinetics of the compounds. The measured data can be fitted well with Kamal-Sourour’s model modified by the diffusion correlation according to Chern and Poehlein. After that, the influence of filler content and size on the kinetic parameters are presented discussed. The results show that the ultimate glass transition temperature is significantly lower for pure epoxy resin (EP) than for compounds filled with surface-treated glass beads, which have an essential effect on the diffusion-controlled reaction at different curing temperatures. For the surface-treated glass beads used in this study, the reaction speed in the early curing stage is accelerated by increasing filler content or decreasing of filler size. In the later curing stage, the reaction speeds of compounds with higher filler content or smaller fillers reduce more quickly. The study of reaction kinetics indicates that the activation energy Ea1, Ea2, the reaction order m, and n are affected differently by varying filler content and size

Identification of a residue in hepatitis C virus E2 glycoprotein that determines scavenger receptor BI and CD81 receptor dependency and sensitivity to neutralizing antibodies.

Hepatitis C virus (HCV) infection is dependent on at least three coreceptors: CD81, scavenger receptor BI (SR-BI), and claudin-1. The mechanism of how these molecules coordinate HCV entry is unknown. In this study we demonstrate that a cell culture-adapted JFH-1 mutant, with an amino acid change in E2 at position 451 (G451R), has a reduced dependency on SR-BI. This altered receptor dependency is accompanied by an increased sensitivity to neutralization by soluble CD81 and enhanced binding of recombinant E2 to cell surface-expressed and soluble CD81. Fractionation of HCV by density gradient centrifugation allows the analysis of particle-lipoprotein associations. The cell culture-adapted mutation alters the relationship between particle density and infectivity, with the peak infectivity occurring at higher density than the parental virus. No association was observed between particle density and SR-BI or CD81 coreceptor dependence. JFH-1 G451R is highly sensitive to neutralization by gp-specific antibodies, suggesting increased epitope exposure at the virion surface. Finally, an association was observed between JFH-1 particle density and sensitivity to neutralizing antibodies (NAbs), suggesting that lipoprotein association reduces the sensitivity of particles to NAbs. In summary, mutation of E2 at position 451 alters the relationship between particle density and infectivity, disrupts coreceptor dependence, and increases virion sensitivity to receptor mimics and NAbs. Our data suggest that a balanced interplay between HCV particles, lipoprotein components, and viral receptors allows the evasion of host immune responses
