Identifying Environmental Factors Influencing Golden Eagle Presence And Reproductive Success, Ross H. Crandall

Graduate Student Theses, Dissertations, & Professional Papers

Declining populations of plant and animal species is a major concern threatening global biodiversity. If we want to conserve threatened species, we must understand the requirements of the species. Recent data suggests Golden Eagle populations in the Western United States are declining. Future threats from expanded energy development, habitat loss and climate change are also a concern. Apparent declines and perceived threats have caused management agencies to classify the Golden Eagle as a species of concern requiring the creation of conservation plans. Yet, an effective conservation plan is dependent on information that is currently lacking. To address this lack of …

Exotic Invasive Plants Drive Different Ecosystem Processes Than Natives In Montana Grasslands, Morgan Marie Luce

Graduate Student Theses, Dissertations, & Professional Papers

Invasion is associated with unexpected increases in aboveground net primary productivity and altered ecosystem function, including increased nitrogen availability and cycling. These shifts are well documented, however many previous studies have been observational, focused on a single plant species, or have not examined belowground microbial communities. I combined field and experimental techniques to examine changes in productivity and ecosystem function, and the abundance of ammonia- oxidizing bacteria (AOB) for the exotic invaders Bromus tectorum, Centaurea stoebe, Euphorbia esula, and Potentilla recta. To quantify effects of these invasive species on N cycling and AOB abundance we compared soil from invaded and …

Is Gun Crime Learned? Social Learning Theory And Guns, Krista Pearl Caffrey

Graduate Student Theses, Dissertations, & Professional Papers

This study examines the relationship between specific childhood experiences and the use of guns in crime in a sample of incarcerated males in American prisons. Two specific childhood experiences are examined: exposure to violence in the home and exposure to guns in the home. Utilizing social learning theory, I argue that adult male felons who used guns in the commission of crimes will have had greater levels of exposure to violence and exposure to guns in their childhood home. Using a data set collected by sociologists James Wright and Peter Rossi, I conducted a binary logistic regression to determine the …

The Constitution Of Queer Identity In The 1972 Apa Panel, "Psychiatry: Friend Or Foe To Homosexuals? A Dialogue", Dustin Vern Edward Schneider

Graduate Student Theses, Dissertations, & Professional Papers

This thesis offers a rhetorical criticism of two speeches delivered from a 1972 panel at the American Psychiatric Association (APA): Franklin Kameny’s “Gay, Proud and Healthy” and John Fryer’s “I am a Homosexual.” Both speeches seek to challenge heteronormative constructions of homosexuality through the construction of a positive homosexual identity. Kameny’s speech uses an extensive set of metaphors to deconstruct the sickness theory of homosexual, challenge the role psychiatrists should play in society, re-conceptualize sexuality, and empower homosexual identity. Fryer’s speech enacts a constitutive rhetoric through the use of consciousness raising strategies and a collective coming out narrative which creates …

Already, we are receiving and processing manuscripts for our Fall Issue. God has been good to us.

Exposing The Roots Of Low Self-Efficacy For Math: A Multi-Case Study Of Students In An Urban Middle School, Joshua Emmett, Daniel Hall, Corey Mckenna

International Christian Community of Teacher Educators Journal

This multi-case study of historically low-performing 7th grade students in a math class at an urban middle school employed a theoretical framework based upon Bandura’s Social Cognitive Theory to discover the causes of low self-efficacy for math. The study utilized a cross-case analysis of four students who demonstrated varying degrees of self-efficacy. To serve students similarly situated, Christian teachers need to know what these students are experiencing and an understanding of the causes of low self-efficacy can inform their professional practice. Christian teacher educators can also benefit from understanding the context into which teachers of such students will serve so …

Servant Leadership: Making A Difference In University Tesl Programs, Sarah Tahtinen-Pacheco

International Christian Community of Teacher Educators Journal

Teaching English as a Second Language is a broad field with programs designed to teach students from all languages and cultures around the world. Currently, the field is facing an urgent need for qualified teachers and leaders due to increasingly high numbers of immigrants and refugees. To meet this challenge, universities must have a plan for adequately preparing teachers to work with the growing population of non-native English learners.

Creating these programs require an understanding of ways to support English learners academically, linguistically, and culturally as they transition into English speaking schools. Based on the need for support, this article …

Christ's Crucifixion Reclamation Of The Cross, Gaye Strathearn

Faculty Publications

Twenty-three years ago, I came to BYU as a student. This was a major, life-changing event for me. My mother and grandmother had joined the Church in Australia in 1958, and I spent most of my early life growing up in a very small branch of the Church, small even by Australian standards. You can perhaps imagine my feelings of excitement at the thought of coming to live in the heartland of the Church. It was quite a novel thought that I would be able to go to Church with my roommates.

Time-Dependent Deposition Characteristics Of Fine Coal Fly Ash In A Laboratory Gas Turbine Environment, Robert Laycock, Thomas H. Fletcher

Tests were conducted with deposition times of 20, 40, and 60 min. Capture efficiencies and surface roughness characteristics (e.g., Ra) …

The Effects Of Practice On The Concurrent Performance Of A Speech And Postural Task In Persons With Parkinson Disease And Healthy Controls, Christopher Dromey, K Bo Foreman, Stuart Sondrup, Eon Jarvis, Shawn Nissen, Leland E. Dibble

Faculty Publications

Purpose. Persons with Parkinson disease (PD) demonstrate deficits in motor learning as well as bidirectional interference (the performance of one task concurrently interferes with the performance of another task) during dual-task performance. Few studies have examined the practice dosages necessary for behavioral change in rehabilitation relevant tasks. Therefore, to compare the effects of age and PD on motor learning during dual-task performance, this pilot study examined persons with PD as well as neurologically healthy participants during concurrent performance of postural and speaking tasks. Methods. Seven persons with PD and 7 healthy age-matched and 10 healthy young control subjects were tested …

Cathedral Of Kairos: Rhetoric And Revelation In The “National House Of Prayer”, Richard Benjamin Crosby

Faculty Publications

Traditionally, kairos is defined by its transience. Scholars assume that in order to capitalize on the rhetorical power of kairos, a speaker must capture the “opportune moment” before it passes. his article makes the case that the kairic moment can be sustained indefinitely through the sacralization of physical space. Linking rhetorical theories of kairos as “God’s time” to Mircea Eliade’s discussion of “sacred hierophanies,” the article performs an analysis of the National Cathedral in Washington DC and concludes that rhetoric can circumvent traditional contingencies when deployed within kairic space.

Review: "Of Africa", Aaron Eastley

Faculty Publications

“A truly illuminating exploration of Africa,” suggests Wole Soyinka in the preface of his new book, Of Africa, “has yet to take place.” Soyinka is not writing here of a physical exploration, of course, but of a humanistic or spiritual one. This, at the root, is what the eight essays that comprise Of Africa urge readers to consider: ways in which Africa can lead the world forward into “a deeply craved Age of Universal Understanding.” In Soyinka’s estimation Africa today is very nearly as misapprehended and undervalued by the world at large as ever it was in the past. But …

Oath Rhetoric, Political Identity, And The Case Of Jon Huntsman, Richard Benjamin Crosby

Faculty Publications

Oath rhetoric took center stage during the 2011-2072 presidential campaign, particularly during the Republican primary races. Several conservative organizations invited candidates to sign pledges, vows, or, as I label them collectively, oaths in an effort to secure the candidates' allegiance to particular polices and communities. Through a close concept-oriented analysis of a representative artifact (the Pro-Life Presidential Leadership Pledge) and candidate Jon Huntsman's refusal to sign it, this essay concludes that oaths serve important rhetorical functions at the personal, cultural, and political level. Whereas traditional political argument in the democratic tradition is meant lo create openings for action, oath rhetoric …

Mitt Romney’S Paralipsis: (Un)Veiling Jesus In “Faith In America”, Richard Benjamin Crosby

Faculty Publications

Mitt Romney’s Mormon faith has been a topic of suspicion and debate among Christian conservatives. Romney addressed the issue in a 2007 address titled “Faith in America.” This article argues that Romney’s use of paralipsis helps to explain the divergent popular and academic responses to the speech. Paralipsis may be used as more than a mere stylistic device; it may also be employed as a comprehensive rhetorical strategy in an increasingly polarized political culture.

Corneal Gene Therapy: Basic Science And Translational Perspective, Rajiv R. Mohan, Jason T. Rodier, Ajay Sharma

Pharmacy Faculty Articles and Research

Corneal blindness is the third leading cause of blindness worldwide. Gene therapy is an emerging technology for corneal blindness due to the accessibility and immune-privileged nature of the cornea, ease of vector administration and visual monitoring, and ability to perform frequent noninvasive corneal assessment. Vision restoration by gene therapy is contingent upon vector and mode of therapeutic gene introduction into targeted cells/tissues. Numerous efficacious vectors, delivery techniques, and approaches have evolved in last decade for developing gene-based interventions for corneal diseases. Maximizing the potential benefits of gene therapy requires efficient and sustained therapeutic gene expression in target cells, low toxicity, …

Electrochemical Explanation For Asymmetric Electrowetting Response, Mehdi Khodayari, Nathan B. Crane, Alex A. Volinsky

Faculty Publications

In electrowetting, a droplet/substrate contact angle is modulated by applying a potential difference between the droplet and the substrate. Typically, the droplet potential is changed via an auxiliary electrode dipped in the droplet. Here, it is shown that electrochemical reactions lead to a potential drop on the auxiliary electrode in electrowetting, which degrades the droplet contact angle modulation. The magnitude of this effect depends on the voltage polarity. This problem can be addressed by using a dielectric layer, such as SiO2, which can prevent electrochemical reactions with the electrowetting substrate and the auxiliary electrode.

An Investigation Of The Production Of Ejectives By Native (L1) And Second (L2) Language Speakers Of Q'Eqchi' Mayan, Wendy Baker-Smemoe, Karl Olaw Christian Wagner

Faculty Publications

This study examines the production of voiceless unaspirated stops and ejective stops by native (L1) and second language (L2) speakers of Q'eqchi' to determine (1) whether there were acoustic differences (in voice onset time and burst duration) between voiceless unaspirated stops and ejective stops and (2) whether L2 speakers were more accurate at producing phones that are similar to the native language (voiceless unaspirated stops) than those that are different (ejective stops). Acoustic analyses of the stops produced by the ten L1 and thirteen L2 Q'eqchi' speakers revealed (1) that L1 speakers make a distinction in voice onset time and …

The Influence Of Pornography On Sexual Scripts And Hooking Up Among Emerging Adults In College, Scott R. Braithwaite, Gwen Coulson, Krista Keddington, Frank D. Fincham

Faculty Publications

The explosive growth in access to the Internet has led to a commensurate increase in the availability, anonymity, and affordability of pornography. An emerging body of research has shown associations between pornography and certain behaviors and attitudes; yet, how pornography actually influences these outcomes has not been documented. In two studies (Study 1N=969; Study 2N=992) we examined the hypothesis that pornography influences potentially risky sexual behavior (hooking up) among emerging adults via sexual scripts. Our results demonstrate that more frequent viewing of pornography is associated with a higher incidence of hooking up and a higher number of unique hook up …

Faculty Publications

Individuals with a psychiatric disorder are significantly more likely to have a spouse with a clinical diagnosis—marital concordance. We used a community sample of 304 couples concordant for either Major Depressive Disorder (MDD) or Substance Use Disorders (SUDs) to examine the relationship between marital functioning and gendered patterns of mental health diagnosis onset. For SUD concordance, couples in which wives onset before husbands—in spite of typical later onset for males—reported lower levels of marital satisfaction compared to couples in which the husband onset first. For MDD concordance, couples in which husbands onset with depression before wives—in spite of typical later …

Patient And Provider Attitudes Toward Genomic Testing For Prostate Cancer Susceptibility: A Mixed Method Study, Wendy C. Birmingham, Neeraj Agarwal, Wendy Kohlmann, Lisa G. Aspinwall, Mary Wang, Jay Bishoff, Christopher Decket, Anita Y. Kinney

Faculty Publications

Background: The strong association between family history and prostate cancer (PCa) suggests a significant genetic contribution, yet specific highly penetrant PCa susceptibility genes have not been identified. Certain single-nucleotide-polymorphisms have been found to correlate with PCa risk; however uncertainty remains regarding their clinical utility and how to best incorporate this information into clinical decision-making. Genetic testing is available directly to consumers and both patients and healthcare providers are becoming more aware of this technology. Purchasing online allows patients to bypass their healthcare provider yet patients may have difficulty interpreting test results and providers may be called upon to interpret results. …

Faculty Publications

Satisfaction with physical activity is known to be an important factor in physical activity maintenance, but the factors that influence satisfaction are not well understood. The purpose of this study was to elucidate how ongoing experiences with recently initiated physical activity are associated with satisfaction. Participants (n = 116) included insufficiently active volunteers who initiated a self-directed physical activity regimen and completed daily diaries about their experiences for 28 days. We used multilevel models to examine the associations between experiences with physical activity and satisfaction. Significant between-person effects demonstrated that people reporting higher average levels of positive experiences and lower …

Causes And Consequences Of Dominance And Diversity In Grasslands, Sarah Pinto

Graduate Student Theses, Dissertations, & Professional Papers

Understanding how species coexist and differ in abundance is central to ecology. Theory predicts competitively superior species should dominate systems and suppress diversity, yet many natural communities characterized by dominants are species rich. Understanding how shifts in dominance among species, and the inherent diversity of communities affect ecosystem function is a second central theme in ecology. For example, decreasing the number of species in local communities can reduce the ability of the community to respond to disturbance. These ideas have captured ecologists' attention because anthropogenic pressures are causing many systems to lose species. In my dissertation I focused on processes …

Emerging Technologies: Webcams And Crowd-Sourcing To Identify Active Transportation, J. Aaron Hipp, Deepti Adlakha, Bill Chang, Amy A. Eyler, Robert B. Pless

Brown School Faculty Publications

Over 25% of adults in the US are obese, contributing to 300,000 deaths and costing the US healthcare system $147 billion annually. Federal governments to local non-profit agencies have instituted policy and built environment (BE) changes in effort to reduce obesity and increase physical activity (PA). A challenge in evaluating the success of policy and BE change is the capacity to capture a priori PA behaviors and the ability to eliminate researcher and respondent bias in assessing post-change environments. A novel transdisciplinary collaboration between public health and computer science is presented here with the goal of automatically analyzing existing public …
