The Effects Of Quantitative And Qualitative Feedback On Speaking Fluency Development, Carlos Eduardo Dos Santos

Theses and Dissertations

This study examined the effect of two forms of feedback (qualitatitive and quantitative) on the development of the spoken fluency of English language learners. Sixty-five intermediate- high students from 22 countries and 11 native languages enrolled in an intensive English language program at the English Language Center, Brigham Young University in Provo, Utah, participated.Throughout the 11-week course, the treatment group (consisting of 33 participants) received feedback on a weekly basis during speaking assessment tasks. The first form of feedback consisted of a quantitative analysis of their spoken fluency. This analysis, performed by PRAAT acoustic analysis software, measured several key features: …

"No Goin' Back": Modernity And The Film Western, Julie Anne Kohler

Theses and Dissertations

This thesis is inspired by an ending—that of a cowboy hero riding away, back turned, into the setting sun. That image, possibly the most evocative and most repeated in the Western, signifies both continuing adventure and ever westward motion as well as a restless lack of final resolution. This thesis examines the ambiguous endings and the conditions leading up to them in two film Westerns of the 1950s, George Steven's Shane (1953) and John Ford's The Searchers (1956). Fascinatingly, the tension and uncertainty conveyed throughout these films is also characteristic of life in modernity, a connection which has previously gone …

A Model Of Children's Acquisition Of Grammatical Word Categories Using An Adaptation And Selection Algorithm, Teresa Young

Theses and Dissertations

Most children who follow a typical developmental timeline learn the grammatical categories of words in their native language by the time they enter school. Researchers have worked to provide a number of explicit, testable models or algorithms in an attempt to model this language development. These models or algorithms have met with some varying success in terms of determining grammatical word categories from the transcripts of adult input to children. A new model of grammatical category acquisition involving an application of evolutionary computing algorithms may provide further understanding in this area. This model implements aspects of evolutionary biology, such as …

Elastic Energy Absorption Via Compliant Corrugations, Sean S. Tolman

Theses and Dissertations

Elastic absorption of kinetic energy and distribution of impact forces are required in many applications. This may be achieved through the use of compliant corrugations. An innovative padding concept is investigated for such applications. Also, recent attention given to the potential for using origami in engineering applications may provide new corrugation configurations that are advantageous for energy absorption and force distribution. This work explores three areas related to these concepts.First, the parameters of a compliant, corrugated padding concept are investigated using Finite Element Analyses (FEA) and physical testing. The shape of the corrugation cross section is explored as well as …

Discovery Of An Allosteric Site On Furin, Contributing To Potent Inhibition: A Promising Therapeutic For The Anemia Of Chronic Inflammation, Andrew Jacob Gross

Theses and Dissertations

Release Date: October 2017

Anemia of chronic inflammation (ACI) is a condition that develops in a setting of chronic immune activation. ACI is characterized and triggered by inflammatory cytokines and the disruption of iron homeostasis. Hepcidin, a small peptide hormone, is the master regulator of iron homeostasis, and rapidly responds to iron supply and demand. Under conditions of chronic inflammation, hepcidin is elevated, and alters the way that iron is absorbed and disrupted throughout the body, resulting in disrupted iron homeostasis through inhibition of the iron exporter protein ferroportin. Anemia arises when insufficient erythropoietic activity combined with inadequate iron supply …

How We Feel About How We Talk: A Language Attitude Survey Of Utah English, David Matthew Savage

Theses and Dissertations

Research has shown that Utah English is a distinct variety of English, particularly as spoken in the Wasatch front region (Lillie 1998). It is characterized by particular linguistic features, including tense/lax vowel mergers before tautosyllabic /l/ (Di Paolo and Farber 1990) and the oral release of glottal stops in certain environments (Eddington and Savage 2012). The features of this variety have been studied; however, not much research has been done about the positive or negative attitudes people hold toward it. Casual observation indicates that Utahans themselves may judge speakers of this variety more harshly than do people from other regions. …

This study aims to provide a better understanding of Native American women veterans’ experiences using data from the Veteran Administration and Indian Health Services. Fifteen interviews were conducted with special attention to quality and quantity of health and mental health care services available to veterans, the barriers and local contextual factors in accessing and utilizing services, and potential solutions to service gaps for women veterans from two Montana reservations, the Northern Cheyenne and Flathead Confederated Salish and Kootenai Tribes. American Indians and Alaska Natives serve at a higher rate in …

Unexpected Dramatic Change In Psychotherapy: Comparing Three Methods, Joseph Richard Horner

Theses and Dissertations

Unexpected dramatic changes in psychotherapy have been observed historically and tied to high recovery rates. Many different methodologies that identify these changes are assumed to be capturing similar or identical phenomena. This study compared three methods – Sudden Gains (SG), Percentage Increase – 50% (PI-50%), and Rapid Response (RR) - in a large database looking for similarities and differences. Results suggest that there are significant differences between SG, RR, and PI-50 as methods for operationally defining unexpected dramatic treatment response, and caution should be used when referring to SG, PI-50, and RR as the same phenomenon or interchangeable terms for …

“One More Drinkin’ Song”: A Longitudinal Content Analysis Of Country Music Lyrics Between The Years 1994 And 2013, Keith Mckay Evans

Theses and Dissertations

The lyrical content of pop music has rarely been studied, particularly for country music. The lyrics of the top 50 country songs for each year between 1994 and 2013 were coded for violent, sexual and substance use-related content. Violence had increased, as had sexual references, substance use, and substance use associated with sexual activity. Of particular note is the frequency of references to alcohol; 21% of the 1,000-song sampling frame contained alcoholic references, and the average for the final five-year period (2009-2013) was 1.01 references per song. This research should serve as a springboard into further studies about the lyrical …

Examining The Social Affordances Of Communication Technology On Human Relations: A Critique Of Networked Individualism From The Perspective Of The Ethical Phenomenology Of Emmanuel Levinas, Michael Lee Wood

Theses and Dissertations

In this thesis, I ask how our understanding of human relations carries implications for the way we understand the affordances of communication technology on human relations. To this end, I examine and compare two opposed perspectives of human relations and social life. The first perspective, networked individualism, is a version of network theory that begins with a foundation of agentic individuals who actively construct and manage their social worlds. Levinasian relationalism, the second perspective, offers a contrasting view that sees human relations as constitutive of human subjectivity. In comparing these two perspectives, I argue that networked individualism is an inadequate …

Objective Science Of Biased Philosophy: Does Naturalism Play A Dogmatic Role In Psychology?, Shannon Starks

Theses and Dissertations

Students and consumers of psychological science are routinely taught that the scientific approach used in psychological research facilitates its providing the most accurate information about human behavior. Because this approach to knowledge acquisition is supposed to be based on objective evidence and systematic reasoning rather than the biased interpretation of other approaches, these other approaches are often marginalized as being inferior. Critics of these claims assert that psychological science is subject to biases just as other approaches are and that the philosophy of naturalism not only pervades, but is also hidden and largely unquestioned in mainstream psychology. This study examines …

For Peat's Sake: The Influence Of Student-Led Evaluations On Small Nonprofits, Rilee A. Buttars

Theses and Dissertations

Development evaluation is a booming business often seen as a development activity in its own right. Yet, not every actor in the field engages with evaluation. This is primarily due to inadequacies in time, data, resources and expertise. These challenges are prevalent among small nonprofits that arguably stand most in need to appraise their extensive efforts. In an accountability-focused environment, these organizations not only fail to assess adequately the impact of their work but also to evaluate reflectively their structure and implementation process. In response, the sociology and international studies departments at Brigham Young University set up an internship that …

In Search Of An Author: From Participatory Culture To Participatory Authorship, Rachel Elizabeth Meyers

Theses and Dissertations

The question of fidelity, which has long been at the center of adaptation studies, pertains to the problem of authorship. Who can be an author and adapt a text and who cannot? In order to understand the problem of fidelity, this thesis asks larger questions about the problems of authorship, examining how authorship is changing in new media. Audiences are taking an ever-increasing role in the creation and interpretation of the texts they receive: a phenomenon this thesis refers to as participatory authorship, or the active participation of audience members in the creation, expansion, and adaptation of another's creative work. …

Mathematical Telling In The Context Of Teacher Interventions With Collaborative Groups, Brandon Kyle Singleton

Theses and Dissertations

Teacher telling is underrepresented in the mathematics education reform literature and deserves additional scrutiny. This case study examined a skilled teacher's telling practices during a university mathematics content course for pre-service elementary teachers. I identified telling practices through discourse analysis, attending to the presence of mathematics and the contribution of new structure or ideas from the teacher. The teacher utilized seven unique types of mathematical telling while supporting collaborative group work on tasks. The study identified subtle telling, implicit telling, and explicit telling. The results suggest that mathematical telling is an integral part of the teacher's role in inquiry-based instruction …

"Making Ourselves Over In The Image Of The Imagery": Overcoming Alienation Through Poetic Expressions Of Experience, Jacqueline Aquino Teusch

Theses and Dissertations

My focus for this essay is on understanding the rhetorical process that occurs when people come together despite their differences—that is what rhetoric is all about. Kenneth Burke argues that this process, for alienated people especially, happens poetically, more than semantically because there are too many differences to overcome semantically between alienated people and the dominant community. This essay is about how the rhetorical process of identification as described by Burke helps us to explain how we cross barriers that divide people who are different to create moments of mutual understanding—identification. In this essay, I look at the experience of …

Hecke Eigenvalues And Arithmetic Cohomology, William Leonard Cocke

Theses and Dissertations

We provide algorithms and documention to compute the cohomology of congruence subgroups of the special linear group over the integers when n=3 using the well-rounded retract and the Voronoi decomposition. We define the Sharbly complex and how one acts on a k-sharbly by the Hecke operators. Since the norm of a sharbly is not preserved by the Hecke operators we also examine the reduction techniques described by Gunnells and present our implementation of said techniques for n=3.

International Congress on Environmental Modelling and Software

The objective of this study was to develop and qualitatively evaluate a model predicting transmission of manure-borne pathogens between co-grazing cattle and wildlife. The developed add- on module SIR that we coupled with SWAT model included the following new components: wildlife population changes, resource selection, dose-response, compartmental susceptible-infectious- recovered (SIR) module and pathogen shedding. Probabilities of the wild and domestic animal infection by pathogens and numbers of infected animals were computed based on a dose-response approach, which included beta-Poisson and exponential models. Land use and plant biomass predicted with watershed-scale model SWAT were used as the input for the deer …

The Effect Of Recovery On Modeling Inactivation Of Bacillus Spores On Hvac Filters, Bharathi Murali, Jade Mitchell

International Congress on Environmental Modelling and Software

The ability of microorganisms to persist on fomite surfaces is an important component in modeling their spread in physical environment. For example, Bacillus anthracis (Ba) spores have been found to be extremely resistant to inactivation, environmental stresses, and stable over decades. Modeling the inactivation of spores could form an integral element for estimating the exposure and the subsequent health risks posed by them. However, there is a knowledge gap in the quantification of recovery of Bacillus spores on porous surfaces, which may have a significant effect on the quantification of their persistence in the environment. Our work investigates the recovery …

Comparison Of One-Dimensional Turbulence And Direct Numerical Simulations Of Soot Formation And Transport In A Nonpremixed Ethylene Jet Flame, David O. Lignell, Garrison C. Fredline, Adam D. Lewis

Faculty Publications

Accurate models of soot formation in turbulent flames are important for correctly predicting and simulating flames and fires. Modeling soot formation and transport is challenging due to the complex chemical formation processes, and differential diffusion of soot relative to a flame. Direct numerical simulations (DNS) have highlighted the importance of such transport on soot concentrations, however DNS is computationally expensive. The one-dimensional turbulence (ODT) model is able resolve a full range of length and timescales and solves the evolution of diffusive and reactive scalars in the natural physical coordinate. We present results of soot formation in ODT and compare the …

Vaccination Status And Attitudes Of Urban School Employees In Utah, Kim Estella Thompson

Theses and Dissertations

Individuals who work with children are at risk for exposure to vaccine-preventable diseases. School settings can quickly become outbreak centers for communicable infection since school employees are in direct contact with children in confined areas for many hours each day. Therefore, it is important for school employees to be fully vaccinated. There are many reasons school employees may be inadequately vaccinated. One common myth is that adults believe vaccines are only for children. Another reason for inadequate vaccination rates among school employees is that many adults believe vaccinations received during childhood are still effective. Healthcare providers (HCPs) constitute the first …

Understanding L1-L2 Fluency Relationship Across Different Languages And Different Proficiency Levels, Olga Vyacheslavovna Maletina

Theses and Dissertations

The purpose of this research was to better understand the relationship between L1 and L2 fluency, precisely, whether there is a relationship between L1 and L2 temporal fluency measures and whether this relationship differs across different languages and different proficiency levels. In order to answer these questions, L1 and L2 speech samples of the same speakers were collected and analyzed. Twenty-five native speakers and 45 non-native speakers of Japanese, Mandarin Chinese, Portuguese, Spanish, and Russian were asked to respond to questions and perform picture descriptions in their L1 and L2. The recorded speech samples were then analyzed by means of …

Changing Attitudes Toward Homosexuality In The United States From 1977 To 2012, Ellen Decoo

Theses and Dissertations

Support for civil rights for gays and lesbians has been increasing nationally. Changes in attitudes may be due not only to the influence of younger, more progressive cohorts, but also to the influence of other factors such as education, religious attendance, political identity, and attitudes toward women's roles. This thesis utilized General Social Survey data from 1977 to 2012 and examined changes in response to attitudinal questions regarding civil rights for gays and lesbians, as well as demographic factors predictive of changing attitudes. Between 1977 and 2012, attitudes became more accepting of civil rights for homosexuals in the United States. …

Perilous Power: Chastity As Political Power In William Shakespeare's Measure For Measure And Margaret Cavendish's Assaulted And Pursued Chastity, Kelsey Brooke Smith

Theses and Dissertations

William Shakespeare and Margaret Cavendish each published plays and poems focusing on the precarious implications and cultural enactments of female chastity in their time. Their lives and writing careers bookend a time when chastity's place in English politics, religion, and social life was perceived as crucial for women while also being challenged and radically redefined. This paper engages in period-specific definitions of virginity and chastity, and with modern scholarship on the same, to explore the historicity of chastity and how representations of self-enforced chastity create opportunities for female political power in certain fiction contexts. Through a comparison of the female …

Vaccination Perceptions Of School Employees In A Rural School District, Janelle L. B. Macintosh

Faculty Publications

Background: There continues to be a need for increases in adult vaccination rates, especially among those working in environments which may easily become communicable disease outbreak centers, such as school employees in the school environment. The purpose of this study was to evaluate why rural Utah school employees were non-compliant with the influenza and measles, mumps, and rubella (MMR) vaccines, as well as to identify their view on mandatory vaccination policies.

Trauma Of A Perpetrator: Reimagining Perpetrators In Edwidge Danticat's The Dew Breaker, Marinda Quist

Theses and Dissertations

This article studies the possibility of perpetrator trauma in Edwidge Danticat's The Dew Breaker. The article gives a brief historical background of the political violence in Haiti that occurred under the Duvalier dictatorship and focuses specifically on the role of Tonton Macoutes, the violent enforcers of much of Duvalier's oppression. Drawing on trauma theory, the article argues that perpetrators have been very little studied within trauma studies because of the possible moral implications of giving research time to individuals who have often chosen their own path of violence. Along with theorists such as Kali Tal and Dominick LaCapra, this article …
