Volume I. William Alexander Hill: Pianist, composer, arranger, bandleader, and vocalist in the early Swing Era of jazz. Volume II. Exegesis (Original composition)

Hill, Augustus Ormonde University of Michigan 2002 해외박사(DDOD)

From about 1925 until his death, William Alexander Hill (1906–1937) worked with and for many of the most prominent jazz practitioners of the era. This included Louis Armstrong, Earl Hines, Fats Walter, Duke Ellington, Joe Oliver, Claude Hopkins, Andy Kirk, Alphonso Trent, and many others. Hill was well respected among his fellow musicians yet, for various reasons, and like may others from the period, never won the public recognition he rightly deserved. Volume I of this dissertation seeks to present a cohesive view of his life and music. Measurement of his musical style and musical output involved examining selected compositions, arrangements, and recordings, and discussing them through means of transcriptions and analysis. The first chapter serves as the introduction to the study. Chapter two examines Alex Hill's background and places him within a particular family unit, geographical area, culture, and historical period. Chapter three explores his development and work as a pianist while chapter four does the same in relation to his production as an arranger. The appendices include a compiled discography and list of compositions and collaborations. Volume 11 of the dissertation consists of <italic>Exegesis</italic>, an original composition for tenor solo, chorus and orchestra (flute, oboe, Bb clarinet, bassoon, F horn, trumpet, trombone, tuba, 2 percussion, piano, and strings). The composer extracted the text from portions of a baccalaureate sermon by Rev. Dr. Andrew H. Hill, father of William Alexander Hill. At the time Rev. Hill served as president of Shorter College in North Little Rock Arkansas, and he delivered this speech to the graduating class of 1911. Published in booklet form and entitled <italic>Mechanism and Mind</italic>, the message highlighted the relationship between Ezekiel the prophet's vision of wheels to the individual person, and to a great cosmos. The composition consists of five movements: <italic>Vision, Creation, Faith, Wheels</italic>, and <italic> Think</italic>. Duration is approximately 20 minutes.

The effects of pre-service school experiences on the attitudes about teaching as a career of freshman teaching fellows at The University of North Carolina at Chapel Hill

Saulsberry, Nichole The University of North Carolina at Chapel Hill 2004 해외박사(DDOD)

The purpose of this research was to examine whether one school exposure model produced freshman UNC-Chapel Hill Teaching Fellows with a more positive attitude toward teaching as a career than the other. This study examined and compared perceptions concerning teaching as a career of freshmen who began UNC-Chapel Hill and the Teaching Fellows program in August 2002. Between September and December 2002 these freshman completed the first semester of program-required and organized school experiences. Of 58 participants, 18 participated in a classroom-based initial school experience under the guidance of several teachers. The remaining 40 students participated in an after-school initial school experience that involved one-on-one interactions with students. All participants completed their initial school experience at an elementary school located in the research triangle. To address the research questions, this study analyzed the results of pre- and post-Likert-scale surveys distributed and collected by The University of North Carolina at Chapel Hill's Teaching Fellows program as part of its internal program evaluation process. The results of this study showed that participants completing their field experience in the classroom under the supervision of a teacher experienced a non-significant negative change in their attitudes about teaching as a career, while participants completing their field experience after-school working one-on-one with students experienced a significant increase in positive attitudes regarding teaching as a career. Rosenberg's theory of cognitive structure and attitudinal affect was used to guide the discussion of this study's results.

Three Papers on Weak Identification Robust Bootstrap Inference

Garcia, Jose Alfonso Campillo ProQuest Dissertations & Theses The University of 2018 해외박사(DDOD)

This manuscript is composed of three chapters that develop bootstrap methods in models with weakly identified parameters. In the first chapter, joint with Jonathan B. Hill, we introduce an asymptotically valid wild bootstrapped t-test, which pro. In the second chapter, joint with Jonathan B. Hill, we introduce a parametric bootstrap that provides an alternative approach to construct statistical tests when parameters are weakly identified. The method extends the parametric bootstrap in re. In the final chapter, we consider the mixed data sampling (MIDAS) model proposed by Ghysels, Santa-Clara, and Valkanov (2005) to evaluate the empirical performance of the wild bootstrapped robust t-test of Chapter 1 and the parametric bootstrapp.

Separating the Signal from the Noise: An Examination of Student and Teacher Scores Based on Student Learning Objectives (SLOs) in One State

Buckley, Katie Hills Harvard University ProQuest Dissertations & Theses 2015 해외박사(DDOD)

Despite the prevalence of student learning objectives (SLOs) in teacher evaluation systems throughout the United States, research on the validity of student and teacher SLO scores used for high-stakes decisions is lacking. For this reason, this dissertation is comprised of two chapters that examine student and teacher-level SLO performance data from select districts in one Race to the Top state. In Chapter 1, I describe the quality of student assessment data and the comparability of student scores across alternative growth targets. I find that in the first year of implementation, assessments from half of the courses in the sample contained indicators of poor data quality, including anomalous score distributions and small to negative correlations between student prescores and postscores. However, in the second year of implementation, when student SLO performance is incorporated into final teacher evaluation scores, far fewer assessments contained anomalous score distributions, and there is no evidence to suggest manipulation of student scores. In addition to the assessments, the choice of student growth target does have an impact on the comparability of student and teacher scores across districts and years. Chapter 2 describes the validity and reliability of teacher SLO scores. I find that while teacher SLO scores are moderately stable across courses, they are not stable over time, likely due to changes made to the assessments and targets used to determine student SLO scores. Further, for teachers with both SLO scores and an alternative metric of performance based on student growth, the two metrics do not converge. Finally, teachers in courses with higher average student prescores and lower proportions of students with disabilities have slightly higher SLO scores. In general, results on teacher SLO scores were similar to those found with value-added based metrics of teacher performance. Findings from both chapters suggest that improvement in the quality of the assessments administered as well as greater consistency in the growth targets assigned to students, both within districts over time and across districts, will improve the validity of student and teacher SLO scores in this state.

Black freedom and the University of North Carolina, 1793--1960

Chapman, John K The University of North Carolina at Chapel Hill 2006 해외박사(DDOD)

Recent histories of the University of North Carolina trivialize the institution's support for white supremacy during slavery, Reconstruction, and Jim Crow, while denying that this unjust past affects the university today. The celebratory lens also filters out African American contributions to the university. In fact, most credit for UNC's increased diversity is due to the struggles of African Americans and other traditionally disenfranchised groups for equal rights. During both the 1860s and the1960s, black freedom movements promoted norms of democratic citizenship and institutional responsibility that challenged the university to become more honest, more inclusive, and more just. By censoring this historical viewpoint, previous scholarship has contributed to a culture of denial and racial historical amnesia that heralds UNC as the "University of the People," without seriously engaging questions of justice in the past or the present. This dissertation demonstrates that before 1865, the gentry used the university to promote the growth of slavery. Following Emancipation, university trustees led the white supremacy campaign to suppress black freedom and Radical Reconstruction. At the turn of the century, university leaders organized the movement for black disfranchisement and segregation that led to Jim Crow. Until the 1960s, the university enforced Jim Crow in its employment practices and its relations with the Town of Chapel Hill. Throughout its history, black workers were the main force challenging UNC's institutional racism on campus, in Chapel Hill, and throughout the state. An extended Epilogue examines how the university's institutional culture changed during the 1960s from an open defense of Jim Crow to acceptance of non-discrimination. Although the university accepted formal equality in admissions, employment, and its relations with the larger community, it did not acknowledge or attempt to dismantle the institutional structures of white supremacy that it had helped to create throughout its history. In this way, UNC established a paradigm of diversity without justice to replace Jim Crow, replacing the open celebration of white supremacy with new forms of subtle, "colorblind" institutional racism that persist today.

Deformable solid modeling via medial sampling and displacement subdivision

Thall, Andrew Lewis The University of North Carolina at Chapel Hill 2004 해외박사(DDOD)

Discrete m-reps use tolerance-based, sampled medial skeleta as an underlying framework for boundaries defined by displaced subdivision surfaces. They provide local and global shape information, combining the strengths of multiscale skeletal modeling with the multi-resolution, deformation and shading properties afforded by subdivision surfaces. Hierarchically linked medial figures allow figural, object-based deformation, and their stability of object representation with respect to boundary perturbation shows advantages of tolerance-based medial representations over Blum axis and Voronoi-based skeletal models. M-rep models provide new approaches to traditional computer graphics modeling, to physically based modeling and simulation, and to image-analysis, segmentation and display, by combining local and object-level deformability and by explicitly including object-scale, tolerance and hierarchical level-of-detail. Sampled medial representations combine the solid modeling capabilities of constructive solid geometry with the flexibility of traditional b-reps, to which they add multiscale medial and boundary deformations parameterized by an object-based coordinate system. This thesis research encompassed conceptual development on discrete m-reps and their implementation for MIDAG (the Medical Image Display and Analysis Group) at UNC-Chapel Hill. Prototype and application code was created to support the following: medial atoms in 3D that included a quaternion frame to establish a local coordinate system; data structures for medial mesh topologies; a new algorithm for interpolating Catmull-Clark subdivision surfaces for m-rep boundaries; a medially based coordinate system parameterizing the m-rep boundary, interior, and local exterior; displacement texturing and displacement meshing of m-rep boundaries; methods of medially based deformation; figure/subfigure blending by implicit surface methods or (with Qiong Han) using remeshing of subdivision boundaries; and C++ code libraries for m-rep modeling in geometric design and image-segmentation applications. Along with discussion of these achievements, this document also includes discussions of current m-rep applications and of design-methodology issues for m-rep-based modeling systems.

Does a sensitive palate beget sensitive mood? The relation between supertasting and disordered mood

Van Meter, Anna R The University of North Carolina at Chapel Hill 2013 해외박사(DDOD)

Objective Prevalence rates of bipolar disorder may be as high as 11% (Angst et al., 2003); currently, research is being conducted on biologically-based traits, with the goal to find ways to ascertain a person's risk for bipolar disorder, or to lend greater certainty to a diagnosis. One trait of interest is an individual's ability to taste phenothioureas, a family of bitter-tasting compounds (Wooding, 2006). The aim of the present study is to determine whether this taste sensitivity has utility as a biomarker for mood disorder risk and, if so, whether emotional reactivity and regulation moderate this relation. Method Participants (N =499) were undergraduates at the University of North Carolina at Chapel Hill. Participants completed a series of questionnaires related to their mood, emotion regulation, and family history of psychiatric disorder. Next, participants completed a mood induction paradigm. Finally, participants' taste sensitivity was measured. Results Three groups, based on taste sensitivity, were identified. Ratings of hypomania, family history of psychiatric disorder, psychological treatment seeking, and emotion regulation did not differ across groups. Scores on the BDI were related to taste sensitivity ( p <.05), but this relation was driven primarily by outliers. Using regression, tasting predicted stronger responses to both positive and negative mood inductions (p<.05). Additionally, the interaction of negative emotion regulation and tasting predicted weaker responses to the mood inductions. Finally, emotion regulation strategies were predictive of both depression and hypomania scores ( p <.05). Testing the effect sizes against the zone of indifference (r= ±0.2), only the emotion regulation strategies showed promise as predictors of mood disorder. Discussion The present study represents the largest sample investigating mood and supertasting. Therefore, the low - or absent - effect size of taste sensitivity in the present analyses sheds doubt on the utility of taste sensitivity as a biomarker for mood disorder risk. However, there were trends to suggest that supertasters are more sensitive to their environment than nontasters and that they may have increased risk for depression. Additionally, taste - or threat - sensitivity may interact with negative emotion regulation strategies in intriguing ways. Future studies, using a clinical sample, may help to better elaborate the trends found in this study.

Staging "the drama": The continuing importance of cultural tourism in the gaming era

Thompson, Matthew D The University of North Carolina at Chapel Hill 2009 해외박사(DDOD)

Issues of indigenous self-representation are of major concern for U.S. tribal nations. For the Eastern Band of Cherokee Indians (EBCI) self-representation has meant refashioning the way they are portrayed in a major theatrical production on their reservation. My dissertation investigates the reinvention of the outdoor drama Unto These Hills, produced 1950-2004 in Cherokee, North Carolina, by the White dominated Cherokee Historical Association (CHA) and the role of the EBCI in exerting tribal sovereignty over the formerly non-Indian controlled institutions which produce representations of their history and culture for tourists. In 2006, under Cherokee management, the fifty-seven year old drama was transformed into Unto These Hills...a Retelling. My research explores the social conflicts, negotiations, creative processes and performances surrounding this change as the tribe steered its most public representation of the past from a narrative of accommodation to one of Cherokee nationalism. This study makes a significant contribution to the history of the EBCI, focusing on the relationships between tribal government and the business of tourism within the broader context of social change on the reservation since the advent of Indian gaming. From the rise of the railroads and highways that laid the foundations for a tourism boom in the 1950s, to the drama's contemporary role within a reservation-wide program for tribal economic development, cultural tourism has been important in the construction of contemporary Cherokee subjectivities and part of a process of Cherokee nation building. As such, the drama is also a source of friction among its multiple audiences who contest each other's authority to authenticate its narratives of the past. Through ethnography my research will elucidate the agency of display as social process. From the ruin of the old CHA to the political maneuvers that sculpted the re-writing of the script and the tribal and federal policies that set the transformation in motion, it is this process of staging the drama, as much as the performance itself, that best illustrates what it means to be Cherokee in the twenty-first century.

Insufficient reason: An interpretation and critique of Kant's categorical imperative (Immanuel Kant)

Johnson, Andrew Burkitt The University of North Carolina at Chapel Hill 2001 해외박사(DDOD)

Kant's moral theory, along with Utilitarianism and Virtue Ethics, is one of the three leading moral theories in contemporary Western moral philosophy. I argue in this dissertation, however, that Kant's moral theory suffers from deeper flaws than its proponents have acknowledged—flaws that render it untenable. But a great deal of interpretative argument must be done before this critique can be compelling, since every critique rests on interpretative presuppositions that are liable to be questioned. Hence the dissertation also spends significant time working out the most charitable reconstruction of the “supreme principle” of Kant's moral theory, the Categorical Imperative. Chapter I is devoted to identifying which of Kant's formulations of the Categorical Imperative should be taken as most plausible and most worth critical examination. I argue in favor of the so-called Formula of the Law of Nature. Chapter II analyzes the crucial concept of a maxim—what a maxim contains and how maxims are to be identified—and defuses two common types of objection to the Categorical Imperative that rest on misunderstandings of the nature of a maxim. In Chapter III, I argue against several leading Kantian ethicists that Kant takes all nonmoral motives to be self-interested, aiming at one's own pleasure; this thesis is presupposed at a number of points by my interpretation of Kant's moral theory. Chapter IV explicates the Universalizability Test that follows from the Formula of the Law of Nature, with particular attention given to Kant's famous four examples from the <italic>Groundwork of the Metaphysics of Morals</italic>. Finally, Chapter V develops a number of criticisms of the Universalizability Test, considering and rebutting defenses that prominent Kantian ethicists have utilized or would be likely to utilize.

Completeness as an ideal for moral theory (Henry Sidgwick)

McKeever, Sean David The University of North Carolina at Chapel Hill 2001 해외박사(DDOD)

Must an acceptable moral theory be systematic and complete? Most philosophers agree we have no such theory now—at least not one which is plausible in other respects. But perhaps we should strive for such a theory and regard our current incomplete theories as at best useful stepping stones. Some theories, such as hedonistic utilitarianism, hold out the promise of being complete: provided all the empirical facts one could, in principle, determine whether any given act was right or not. Other theoretical approaches seem much further from being complete, and it is not obvious how they might be refined to become fully complete in the future. Though completeness is surely not the only reason for thinking a theory acceptable, is it some reason?. I approach this question by considering, at first, Henry Sidgwick's views. Sidgwick's defense of utilitarianism is often dismissed on the grounds that it relies on a spurious moral epistemology: rational intuitionism. This worry is based on a misunderstanding, though. Once we properly appreciate the way Sidgwick employs the notion of an “intuition,” we can see that Sidgwick does not rely on those features of rational intuitionism that most philosophers find objectionable. By contrast, I claim that Sidgwick does rely on a powerful and under-examined assumption about the standards a fully acceptable moral theory must meet. Specifically, I show that Sidgwick relies upon the claim that any ideally acceptable moral theory must enable us, in principle, to determine the rightness of any act, provided all the empirical facts. I call this the Completeness Assumption. Some may find Sidgwick' reliance on such an assumption every bit as suspicious as any reliance on rational intuitionism. Against this, I argue that plausible views about the nature of morality (views which Sidgwick nicely articulates and which do not presuppose consequentialism) provide the resources for a powerful argument in favor of the Completeness Assumption. Many philosophers have objected to the Completeness Assumption. I argue that contemporary attempts to reject the Completeness Assumption (advanced by Korsgaard and Nagel and suggested by Gibbard) misfire. Thus, I claim we have good reason to accept the Completeness Assumption. However, the fact that a theory (hedonistic utilitarianism, for example) satisfies the Completeness Assumption turns out not to be a reason to accept it. Consequently, Sidgwick's argument in favor of utilitarianism is a failure. Those who advance theories and methods that are less systematic and complete need not fear the Completeness Assumption. Those who have tried to resist the Completeness Assumption have done so needlessly.
