Does Mission Matter? Examining the Role of Organizational Mission and Religious Identity in Schools Participating in the Milwaukee Parental Choice Program

For decades, theories of bureaucracy have emphasized the importance of organizational mission in thriving organizations. This dissertation will examine the role of organizational mission in schools, particularly, a sample of schools that participate in the Milwaukee Parental Choice Program, the nation\u27s oldest and largest school voucher program. Using teacher and school leader survey data, coupled with measures of student achievement, it will measure mission coherence and correlate it with a variety of outcome variables of interest. It will also take a particularly close look at the role of mission in religious schools

Rainforests of the mind: Conceiving transnational composition from a mobilities perspective on knowledge.

This research project stems from my experience teaching academic writing at the state university in Qatar. To investigate the factors overdetermining the deeply standardized curriculum there, I draw on scholarship in mobility studies, political economy, and the history both of Qatar and of composition instruction in the US, from which the curriculum is drawn. These explorations ultimately lead me to comment on the fraught enterprise of subjecting writing and language to commodification, which I identify as part of broader trends characterizing neoliberal economic globalization. To further develop this critique, I conduct a critical multi-sited autoethnographic study that questions preconceived notions of correctness in writing, revealing how education is increasingly tied to the demands of global economy. Chapter one develops an anti-essentialist perspective on ideology, demonstrating both the transnational appeal of an autonomous model of literacy and the frictions that deny its claims to universality. In chapter two I delve into the details and history of the Qatar University Foundation Program, looking at how it has been shaped, again, by points of ideological alignment across local and global exigencies. Chapter three takes the autoethnographic approach to the subject of postsecondary instruction in English academic writing, providing both context for my teaching experience in Qatar while substantiating broader observations about how writing knowledge is mobilized according to both local demands and increasingly global ideologies. In chapter four, I return to Qatar to sketch a tactical approach (de Certeau) to working with(in) these trends, situating the work within a broader perspective that aligns with institutional demands while refusing to deny the multifarious points of friction that drive the creation of knowledge

Louisiana Educational Assessment Program (LEAP): A Historical Analysis of Louisiana\u27s High Stakes Testing Policy

Abstract High stakes testing is popularly examined in educational research, but contemporary analyses tend to reflect a qualitative or quantitative research design (e.g., Au, 2007; Cochran-Smith & Lytle, 2006; Gamble, 2010). Exhaustive debate over the relative success or failure of high stakes testing is often framed between competing visions of epistemological constructs, and the historical foundations of high stakes testing policies are rarely explored. The origins of high stakes testing can be traced to local school reform efforts in states like Louisiana, and investigating the roots of high stakes testing at the state level contextualizes the national debate on student assessment in research and scholarship. Using historical research methods, this project details the local campaign to implement the Louisiana Educational Assessment Program (LEAP) as Louisiana’s comprehensive high stakes testing program. Enacted under state law in 1986, the LEAP is a series of K-12 student assessments aligned to prescriptive state standards. The LEAP is among the nation’s longest comprehensive high stakes testing programs and is the centerpiece to Louisiana’s school accountability system. The narrative of its development offers critical insight into the overarching rationales for high stakes testing that continue to drive accountability policies throughout the country. This study interweaves sociological and political history into a singular chronological record of the LEAP. Historical research methodology informs this study by establishing the basis for data collection and analysis. Historical research method is the systematic collection and evaluation of primary source data in order to determine trends, causes, or effects of past events (Gay, 1996; Lucey, 1984). Methods used in this research investigation include document analysis and oral history interviews. Multiple data sources are used to gain a thorough understanding of the historical context surrounding the implementation of the LEAP. The LEAP functions as both a student assessment program and policy of school accountability, and the story of its development is an important narrative within the field of high stakes testing research and scholarship

Galaxy-Scale Signatures of Screened Modified Gravities

In recent years, theories of gravity incorporating a scalar field coupled to gravity---'scalar-tensor' theories---have been subject to increased attention. In these theories, the scalar field mediates gravitational-strength 'fifth forces'. For such scalar fields to retain cosmological relevance while also evading stringent constraints from high-precision post-Newtonian tests of gravity, 'screening mechanisms' are invoked, in which the fifth force is suppressed in regions of high density or deep gravitational potential. One example of a screening mechanism is the 'chameleon' mechanism, in which the scalar has a density-dependent mass, such that the mass becomes very large in regions of high density, and the fifth force is exponentially suppressed as a consequence. While the primary effect of screening mechanisms is to mask the effects of modified gravity in the Solar System, they can nevertheless give rise to interesting astrophysical signatures elsewhere, searches for which can serve as tests of screened modified gravity. These signatures are the subject of this thesis. The Introduction of this thesis in Chapter 1 presents some historical background and scientific context, particularly in the fields of cosmology, the astrophysics of galaxies, and screened modified gravity theories. Subsequently, Chapters 2, 3, and 4 present original research regarding two galaxy-scale signatures of screened modified gravity: 'upturns' in galaxy rotation curves and asymmetries in stellar streams. If a galaxy is partially screened, it will have a 'screening radius', within which the fifth force is suppressed. Outside the screening radius, the fifth force on a test particle will be proportional to the mass enclosed in the shell between the test particle and the screening radius. Thus, the fifth force will contribute to the galaxy's rotation curve, but only outside the screening radius. At the screening radius itself, there will be an upturn in the curve. In Chapter 2, based on an article published in the Monthly Notices of the Royal Astronomical Society (Naik et al., 2018), I give the first prediction of this effect, specifically in the context of Hu-Sawicki f(R) gravity, a widely-studied example of a chameleon theory. By post-processing simulated galaxies of the Auriga Project using the f(R) gravity code MG-Gadget, I produce mock rotation curves for a range of galaxy masses and values of the key theory parameter fR0, forecasting competitive constraints on fR0. In Chapter 3, also based on an article published in the Monthly Notices (Naik et al., 2019), I turn to observational data. Analysing the high-quality rotation curves of the SPARC sample, I find that in certain f(R) parameter regimes there is a strong signal, but it is better explained with standard gravity plus a 'cored' dark matter halo profile than with modified gravity plus a theoretically-predicted 'cuspy' halo. I am thus able to place competitive constraints on f(R) gravity, with the caveat that if cored haloes can not ultimately be motivated under the standard ΛCDM cosmological paradigm, then screened modified gravity could feasibly ease the tension between observed cores and predicted cusps. In Chapter 4, I consider the observable imprints of screening on stellar streams around the Milky Way. For reasonable parameter regimes in chameleon theories, main sequence stars will be screened, and thus neither source nor couple to the fifth force. Thus, a situation can arise in which a dark matter dominated dwarf galaxy is unscreened, but the stars within it are screened. If such a galaxy were to be tidally disrupted by the Milky Way, its stars would be preferentially stripped into the trailing stellar stream rather than the leading stream. The streams would therefore be asymmetric about their progenitor. Using a restricted N-body method, I explore this effect for a variety of satellite orbits and modified gravity regimes. Taking f(R) gravity as a fiducial theory, I forecast some of the strongest constraints to date from future data releases of the Gaia satellite. This chapter is based on an article submitted to Physical Review D (Naik et al., 2020). Finally, Chapter 5 gives some concluding remarks and a discussion of future prospects in this field.This PhD was funded by the Science and Technology Facilities Council (STFC), via a Doctoral Training Partnership

Synopsis of Phasor Monitoring Applications for Wide Area Control and Protection

The phenomenon of voltage collapse in electric power systems has received a considerable amount of attention in the last decade. Although the occurrences of the voltage blackouts have decreased in the recent years, the problem of voltage stability still poses a considerable threat to the security and the reliability of modern electricity grids. The ultimate objective of this thesis is to further investigate and expand upon the existing body of knowledge on the voltage collapse phenomenon and develop protection and control schemes for mitigating such undesirable events in modern electric grids. In doing so, the research done in this thesis work builds on an earlier work done in the area of Voltage Instability Prediction (VIP). Although proven to be a successful metric in determining the proximity of large nonlinear systems to a potential voltage instability event, much remains to be explored in the area of Voltage Instability Prediction. In particular the issues of estimating the static stability margins, the locational dependence of accuracy of such VIP derived margins, the exploitation of redundant local measurements and a compelling argument in favor of combining/fusing the individual VIP margins into a single system-wide measure of voltage collapse margin form the main focus of investigation of this work. To lower the individual entropy of the VIP derived margins, a data fusion algorithm built on the foundations of Dempster-Shafer’s evidential reasoning method is proposed. The research is concluded on a positive note with the final results further pushing the envelope of knowledge in the field of voltage stability studies in power systems

Comparative effects of exercise reduction and relaxation training on type A behavior and dysphoric mood states in habitual aerobic exercisers

This study investigated the comparative effects among habitual (chronic) aerobic exercisers of aerobic exercise reduction to comply with American College of Sports Medicine (ACSM) guidelines and relaxation training on four psychological variables: Type A behavior pattern (TABP), anxiety, depression and hostility. Fifty-seven adult male and female subjects who had averaged at least 6 weekly hours of aerobic exercise for a period of at least one year were interviewed and pretested for Type A behavior using the Jenkins Activity Survey and for anxiety, depression and hostility using the Profile of Mood States. After matching for amount of exercise, gender and age, subjects were randomly assigned to either a control group, an exercise reduction group (5 hours per week or less) or a 5-session relaxation-instruction group. Using pretest scores as covariates, a multivariate analysis of covariance (MANCOVA) procedure was used to test for mean group post-test differences 10 weeks later. No statistically significant differences were found. Reducing exercise to comply with ACSM recommendations for frequency, intensity and duration of exercise had neither positive nor negative effects in terms of TABP or dysphoric mood states

Examining the Systemic Effects of Relational Trust and Network Trustworthiness on School Community: A Multi-Site Case Study of Three Independent Schools

Within the broader context of accountability imposed from beyond our schools, this mixed methods, multi-site case study investigated the development of relational trust and trustworthy relationships as internal accountability structures within three independent schools replicating responsible independence on the scale of the school as trustworthy freedom on the scale of the individual. Interviews, observations, artifacts, sociograms, and surveys were analyzed to identify teacher and administrator perceptions of structures supporting relational trust, accountability to community standards, and sustainable trust-based cultures. Survey data were also analyzed for corresponding evidence of organizational conditions associated with school improvement: teacher orientation to innovation, teacher commitment to school community, peer collaboration, reflective dialog, collective responsibility, focus on student learning, and teacher socialization. Structures found to support responsible freedom at these schools included their historic honor systems, programs for character education, strategic planning, and policies and schedules guiding daily life. Neither structure nor freedom alone was found to be sufficient to sustain cultures built on relational trust and mutual accountability. Inflexible structures or inauthentic, coercive, or incompetent leaders diminished social capital over time at all three schools. Schools enjoying the best organizational conditions for school improvement built capacity by fostering macro-micro feedback loops of honor and trust between the scales of the individual and the school as a professional learning community. Findings were applied to develop a model for individual and organizational capacity building, relating the dimensions of relational trust and accountability to standards. The two-dimensional model for capacity building identified four categories of school capacity based on levels of both relational trust and accountability to standards: low capacity schools, compliant schools, complacent schools, and high capacity schools. The model further developed associated strategies for moving schools in each category towards developing or sustaining high capacity

A Silent-Speech Interface using Electro-Optical Stomatography

Sprachtechnologie ist eine große und wachsende Industrie, die das Leben von technologieinteressierten Nutzern auf zahlreichen Wegen bereichert. Viele potenzielle Nutzer werden jedoch ausgeschlossen: Nämlich alle Sprecher, die nur schwer oder sogar gar nicht Sprache produzieren können. Silent-Speech Interfaces bieten einen Weg, mit Maschinen durch ein bequemes sprachgesteuertes Interface zu kommunizieren ohne dafür akustische Sprache zu benötigen. Sie können außerdem prinzipiell eine Ersatzstimme stellen, indem sie die intendierten Äußerungen, die der Nutzer nur still artikuliert, künstlich synthetisieren. Diese Dissertation stellt ein neues Silent-Speech Interface vor, das auf einem neu entwickelten Messsystem namens Elektro-Optischer Stomatografie und einem neuartigen parametrischen Vokaltraktmodell basiert, das die Echtzeitsynthese von Sprache basierend auf den gemessenen Daten ermöglicht. Mit der Hardware wurden Studien zur Einzelworterkennung durchgeführt, die den Stand der Technik in der intra- und inter-individuellen Genauigkeit erreichten und übertrafen. Darüber hinaus wurde eine Studie abgeschlossen, in der die Hardware zur Steuerung des Vokaltraktmodells in einer direkten Artikulation-zu-Sprache-Synthese verwendet wurde. Während die Verständlichkeit der Synthese von Vokalen sehr hoch eingeschätzt wurde, ist die Verständlichkeit von Konsonanten und kontinuierlicher Sprache sehr schlecht. Vielversprechende Möglichkeiten zur Verbesserung des Systems werden im Ausblick diskutiert.:Statement of authorship iii Abstract v List of Figures vii List of Tables xi Acronyms xiii 1.

Articulation-to-Speech: Optimal hyperparameters 189 Bibliography 191Speech technology is a major and growing industry that enriches the lives of technologically-minded people in a number of ways. Many potential users are, however, excluded: Namely, all speakers who cannot easily or even at all produce speech. Silent-Speech Interfaces offer a way to communicate with a machine by a convenient speech recognition interface without the need for acoustic speech. They also can potentially provide a full replacement voice by synthesizing the intended utterances that are only silently articulated by the user. To that end, the speech movements need to be captured and mapped to either text or acoustic speech. This dissertation proposes a new Silent-Speech Interface based on a newly developed measurement technology called Electro-Optical Stomatography and a novel parametric vocal tract model to facilitate real-time speech synthesis based on the measured data. The hardware was used to conduct command word recognition studies reaching state-of-the-art intra- and inter-individual performance. Furthermore, a study on using the hardware to control the vocal tract model in a direct articulation-to-speech synthesis loop was also completed. While the intelligibility of synthesized vowels was high, the intelligibility of consonants and connected speech was quite poor. Promising ways to improve the system are discussed in the outlook.:Statement of authorship iii Abstract v List of Figures vii List of Tables xi Acronyms xiii 1. Introduction 1 1.1.
