Multiplexed Optofluidics For Single-Molecule Analysis, Matthew Alan Stott

Theses and Dissertations

The rapid development of optofluidics, the combination of microfluidics and integrated optics, since its formal conception in the early 2000's has aided in the advance of single-molecule analysis. The optofluidic platform discussed in this dissertation is called the liquid core anti-resonant reflecting optical waveguide (LC-ARROW). This platform uses ARROW waveguides to orthogonally intersect a liquid core waveguide with solid core rib waveguides for the excitation of specifically labeled molecules and collection of fluorescence signal. Since conception, the LC-ARROW platform has demonstrated its effectiveness as a lab-on-a-chip fluorescence biosensor. However, until the addition of optical multiplexing excitation waveguides, the platform lacked …

The Meaning Of Sexuality: A Critique Of Foucault's History Of Sexuality Volume 1, Anne E. Grow

Theses and Dissertations

Michel Foucault is a celebrated post-structuralist theorist that has helped shape gender and sexual theory. In A History of Sexuality Volume 1 Foucault dismantles many longstanding sexual traditions and morals by exposing them as societal constructs. According to Foucault, anonymous yet fully invasive power sources have shaped and continue to shape sexual culture and more importantly, individual beliefs about sexuality. However, Foucault's obsession with the influence of power limits his sexual theory in three particular ways. First, he disregards the female sexual experience; second, he undermines individual agency; and third, he undermines the innate desire for love and family. The …

Development Of A Real-Time Auralization System For Assessment Of Vocal Effort In Virtual-Acoustic Environments, Jennifer Kay Whiting

Theses and Dissertations

This thesis describes the development of the real-time convolution system (RTCS) for a little-studied talker/listener in virtual acoustic environments. We include descriptions of the high-resolution directivity measurements of human speech, the RTCS system components, the measurement and characterization of oral-binaural room impulse responses (OBRIRs) for a variety of acoustic environments, and the compensation filter necessary for its validity. In addition to incorporating the high-resolution directivity measurements, this RTCS improved on that developed by Cabrera et al. [1] through the derivation and inclusion of the compensation filter. Objective measures in the time- and frequency-domains, as well as subjective measures, were developed …

Measuring The Reliability Of The Early Expository Comprehension Assessment, Revised 3rd Edition, Garrett Frane Wilkes

Theses and Dissertations

During the past several years, the Common Core State Standards has created a greater demand for students in public schools to comprehend and analyze expository text. In order to prepare students for work with expository text, beginning with kindergarten, more emphasis and standards have become prevalent in preschool classrooms as well. The Early Expository Comprehension Assessment, Revised 3rd Edition (EECA R-3) was developed to aid preschool teachers in determining what aspects of expository text a student understands, including recognition of different structure types. This study with the EECA R-3 extends previous studies using earlier iterations of the assessment. One hundred …

The Association Between Articulator Movement And Formant Histories In Diphthongs Across Speaking Contexts, Janae Valyn Christensen

Theses and Dissertations

This study examined the effect of context on the association between formant trajectories and tongue and lip kinematics in the American English diphthongs /aɪ/ and /aʊ/. Seventeen native speakers of American English had electromagnetic sensors placed on their tongue and lips to record kinematic signals that were time-aligned with the corresponding acoustic recording. Speakers produced the diphthongs in isolation, in a single word rVl context, in a phrase hVd context, and in a sentence context. Kinematic data and the F1 and F2 trajectories were extracted from the middle 50% of each diphthong production. To allow direct comparison of signals with …

Multi-Tissue Examination Of Exercise Or Metformin On The Consequences Of Doxorubicin Treatment, Amy Dee Mackay

Theses and Dissertations

Doxorubicin (DOX) is an effective chemotherapeutic treatment with lasting deleterious side effects in heart and skeletal muscle. As an increased percentage of patients live many years past their cancer treatments, addressing the long-term side effects of chemotherapy treatment becomes critical. In an attempt to prevent heart and skeletal muscle damage caused by DOX, two co-treatments, exercise (EX) or metformin (MET) were studied for their effectiveness in maintaining muscle function, mitochondrial respiration and iron regulation. DOX is known to bind with iron, contributing to oxidative damage resulting in cardiac and skeletal muscle toxicity. However, the degree to which the toxic side …

Day-Of-Injury Computed Tomography (Ct) And Longitudinal Rehabilitation Outcomes: A Comparison Of The Marshall And Rotterdam Ct Scoring Methods, Kayla Michelle Alder

Theses and Dissertations

Both individual patient-related and injury-related factors predict functional outcomes following moderate-to-severe traumatic brain injury (M/S TBI). Other than binary outcomes such as death, little is known about the role of day-of-injury neuroimaging in predicting long- term outcomes. Classification systems for assessing the severity of injury using computerized tomography (CT) scans, such as the Marshall Classification System (MCS) or Rotterdam scale, have not been systematically studied to see how they relate to long-term rehabilitation and functional outcomes following M/S TBI. The MCS consists of six categories based on information about midline shift, basal cistern compression, surgery evacuation, and lesion size. The …

This method, used by teaching and learning consultants at BYU, is termed authentic purposeful design. It encourages faculty to succinctly define what their course will help students become, use principles of backward design to align all course elements to that purpose, and teach the course with its core purpose in mind. The course design and teaching methods of 3 faculty members who used authentic purposeful design were studied using a qualitative research approach. Themes emerged …

Effect Of Gyroscope Parameters On Gyroscopic Tremor Suppression In A Single Degree Of Freedom, Brendon Connor Allen

Theses and Dissertations

Although tremor is one of the most common movement disorders, there are few effective tremor-suppressing options available to patients. One potential tremor-suppression device involves a wearable gyrostabilizer similar to those used to stabilize cameras. However, we do not currently know how to design a gyrostabilizer to suppress tremor in an optimal manner. To address this gap, we present a systematic investigation of how gyrostabilizer parameters affect tremor suppression in a single degree of freedom (DOF). A simple model of the hand with a single DOF at the wrist and a gyroscope mounted on the back of the hand was used …

Neuroimmune-Mediated Alcohol Effects On Ventral Tegmental Area Neurons, Stephanie Bair Williams

Theses and Dissertations

Dopamine (DA) transmission is a key player in the rewarding aspects of ethanol as well as ethanol dependence. The current dogma is that DA transmission is increased during ethanol via the inhibition of ventral tegmental area (VTA) GABA neurons and that excitation of VTA GABA neurons during withdrawal results in decreased DA transmission. Microglia, the major neuroimmune effector in the brain, may be a key mediator in this process by releasing cytokines following activation. We evaluated the effect of ethanol on cytokine concentrations in the VTA and NAc using a cytometric bead array, and found that low dose ethanol (1.0 …

A Content-Analytic Meta-Analysis Of Gender Stereotyping In Screen Media, Lee Whitney Essig

Theses and Dissertations

Thousands of studies have investigated the gendered portrayals in various forms of media. Researchers believe that considering gendered media content is important, as gender stereotypes have been found to influence development, often with adverse outcomes. Although a vast body of research on gender stereotypes has accumulated, little effort has been made to synthesize this literature. The purpose of this paper is to collect and analyze the results of content-analytic studies of gender portrayals across several forms of media including television, television commercials, movies, video games, music videos, and various forms of print media into a comprehensive paper on gender stereotypes …

14-3-3zeta Role In Promoting Survival Of Cells To Facilitate Progression Of Cancer, Katie Pennington, Eranga Roshan, Joshua Andersen, Katherine K. Mccormack

Student Works

The regulatory protein 14-3-3z promotes cellular growth and survival, and high expression levels of 14-3-3z are associated with mortality in multiple cancer types. 14-3-3z binds cellular proteins in a phosphorylation-dependent manner to modulate their functions. We have been characterizing the interactome of 14-3-3z which will likely lead to candidates for novel therapies for chemoresistant cancers. Tumor cells must be able to survive in a variety of stresses within the tumor microenvironment, including hypoxia, which occurs when tumors lack adequate blood supply. Previous data from our lab suggested that 14-3-3z promotes the adaptation of tumor cells to hypoxic stress. Our hypothesis …

Perceptual Proficiency Ratings Of Obstruent Productions In L2 Learners Of English As A Function Of Speech Task Type, Word Position, And Listener Expertise, Rachel Mcpherson Zitting

Theses and Dissertations

Second language (L2) learners of English must learn to produce English phonemes, words, and sentences. These L2 learners make many errors when learning English; they may change the place or manner of articulation, insert vowels, or delete consonants. Obstruent sounds, such as fricatives, affricates, and stops, can be especially difficult for L2 learners. This study analyzed native English speakers’ perception of the quality of obstruents produced by native Mandarin Chinese and Korean speakers. Target words containing obstruents had been produced in three different tasks: in a carrier phrase, in a paragraph, and in a spontaneous speech sample. Obstruents were produced …

Gone With The Wind: The Evolving Influence Of Social Movements And Counter Movements On Entrepreneurial Activity In The U.S. Wind Industry, W. Chad Carlos, Wesley D. Sine, Brandon H. Lee, Heather A. Haveman

Faculty Publications

Social movements can disrupt existing industries and inspire the emergence of new markets by drawing attention to problems with the status quo and promoting alternatives. We examine how the influence of social movements on entrepreneurial activity evolves as the markets they foster mature. Theoretically, we argue that the success of social movements in furthering market expansion leads to three related outcomes. First, the movement-encouraged development of market infrastructure reduces the need for continued social movement support. Second, social movements’ efforts on behalf of new markets increase the importance of resource availability for market entry. Third, market growth motivates countermovements that …
