They Soon Forgot Their Words - Documentary, Karen Paulk

Graduate Theses and Dissertations

This documentary film, They Soon Forgot Their Words, is about the language issues that threaten the Kaqchikel Mayan language spoken in Guatemala. It is one of 21 Mayan languages spoken in the country and is one of the most widely used with more than 500,000 speakers. Unfortunately, however, scholars have noticed that Kaqchikel is in a state of “shift” a process where one language combines with another in speech. As is the case with many Mayan languages in Guatemala, Kaqchikel is often combined with Spanish in speech. The colloquial name used for the combining of these two languages is “kaqchinol.” …

Effects Of Genre Tag Complexity On Popular Music Perception And Enjoyment, Lauren Shepherd

Graduate Theses and Dissertations

The popular online streaming platform Spotify added over 1400 genre tags in the last two years. Despite that numerous artists and composition competitions claim to seek projects that “transcend the traditional notion of genre,” the industry has only added more complex and mystifying genre labels. This dichotomy between artists and industry ignores the effects these labels have on consumers. Do more complex genre tags enhance the listening experience for the average consumer by providing additional information about what they are about to hear? The current research seeks to examine the effects of the granularity of genre tags on popular music …

The Evaluation Of Low-Use-Rate Zinc Fertilization Strategies On Seedling Canopy Coverage, Zn Concentration, Biomass, And Grain Yield, Maxwell David Coffin

Graduate Theses and Dissertations

Zinc (Zn) is the most common micronutrient deficiency in flooded rice (Oryza sativa L.). Some new Zn fertilization methods have been advertised, but have limited research supporting their efficacy. This study mainly compared the effect of Zn-seed treatment rate in combination with other low-use-rate Zn-fertilization methods to the standard of 11 kg Zn ha-1 as ZnSO4 on rice early-season canopy cover, tissue-Zn concentration, and grain yield. A secondary objective evaluated an alternative method (to seed treatment with ZnO) of enhancing seed-Zn concentration using post-heading foliar-Zn application on seedling tissue-Zn concentration and grain yield. For the main objective, rice seed was …

Cool And Warm Season Climate Signals In Tree Rings From North America, Max Carl Arne Torbenson

Graduate Theses and Dissertations

Earlywood (EW) and latewood (LW) ring-width chronologies have become an increasingly important proxy in paleoclimate reconstructions. These subannual variables can provide estimates of past hydroclimate variability for seasonal windows that total ring-widths cannot resolve. The strength of the relationship between EW and LW series may influence what type of paleoclimate information is embedded within the tree-ring series. High correlations (> 0.70) between EW and LW are recorded for much of the continent but the magnitude of correlation varies greatly across space and species boundaries. Using four LW chronologies from shortleaf pine, the North American conifer species displaying the lowest EW-LW …

Dominant Leadership Dynamics Of School Administrators Leading Non-Instructional Personnel, Michael Ewton

Graduate Theses and Dissertations

With the literature and many schools and school districts advocating for enhanced communication and engagement with parents, families, and the community at large, it is advisable that school-level administrators consider the manner in which they engage the non-instructional employees who serve their schools. This dissertation explores the dominant leadership dynamics experienced by high school principals responsible for supervising non-instructional support services and leading non-instructional operations personnel in their schools. Trained and expected to be instructional leaders, principals must still ensure their students receive the basic services necessary to maintain a safe and effective learning environment. Ensuring students receive the benefit …

The Interior Structure Of Immigration Enforcement, Eisha Jain

Faculty Publications

Deportation dominates immigration policy debates, yet it amounts to a fraction of the work the immigration enforcement system does. This Article maps the interior structure of immigration enforcement, and it seeks to show how attention to its structure offers both practical and conceptual payoffs for contemporary enforcement debates. First, deportation should not be conceptualized as synonymous with immigration enforcement; rather, it is merely the tip of a much larger enforcement pyramid. At the pyramid’s base, immigration enforcement operates through a host of initiatives that build immigration screening into common interactions, such as with police and employers. Second, this enforcement structure …

Development Of Granulated Adsorbent For Clean-Up Of Water Contaminated By Cesium, Esther Alorkpa

Electronic Theses and Dissertations

A study was conducted on sol-gel synthesis of an adsorbent (phosphotungstic acid embedded in silica gel, H-PTA/SiO­₂) of radioactive cesium. A novelty of this work is covalent bonding of PTA to the surface of solid support that prevents leaching from the surface of the material. The sample was granulated with a binder, aluminium oxide (γ-Al₂O₃). Solid-state NMR and FT-IR spectroscopy were used to confirm the presence of Keggin units of PTA in the bound materials. Thermal analysis of H-PTA/SiO­₂ - γ-Al₂O₃ (50 %) showed that the water content in the …

Biogeography Of Endemic Dragonflies Of The Ozark-Ouachita Interior Highlands, Wade Alexander Boys

Graduate Theses and Dissertations

A common pattern across many taxonomic groups is that relatively few species are widespread while the majority are restricted in their geographic ranges. Such species distributions are used to inform conservation status, which poses unique challenges for rare or cryptic species. Further, priority status is often designated within geopolitical boundaries, which may include only a portion of a species range. This, coupled with lack of distributional data, has resulted in species being designated as apparently rare throughout some portions of their range, which may not accurately reflect their overall conservation need. The Interior Highlands region of the central United States …

Using Peripheral Venous Pressure Waveforms To Predict Key Hemodynamic Parameters, Ali Zohair A Alalawi

Graduate Theses and Dissertations

Analysis of peripheral venous pressure (PVP) waveforms is a novel method of monitoring intravascular volume. Two cohorts were used to study the hemodynamics change of the body state and its influence on the PVP using (1) dehydration setting with infants suffering from pyloric stenosis and (2) hemorrhage setting during a craniosynostosis elective surgery. The goal of this research is to develop a minimally invasive method of analyzing the PVP waveforms and find correlations with volume loss.

"We Are Strangers In This Life": Theology, Liminality, And The Exiled In Anglo-Saxon Literature, Nathan John Haydon

Graduate Theses and Dissertations

In “‘We Are Strangers in this Life’: Theology, Liminality, and the Exiled in Anglo-Saxon Literature,” I analyze the theme of exile in the theological literature of the Anglo-Saxon era as a way of conveying the spiritual condition of eschatological separation. The anthropological theory of liminality will be applied in this dissertation as a way of contextualizing the existence of the exiled, and the multiple ways in which exile is enacted. The intervention of the theory of liminality in this dissertation offers a methodology and vocabulary for assessing what exile means in terms of a spiritual identity, how it operates in …

Ix: Story About The Law Of Non-Discrimination - Documentary, Denzel Jenkins

Graduate Theses and Dissertations

The purpose of this project is to provide historical awareness for how Title IX, the anti-gender discrimination law in education, evolved to where it is today and the impact it has on universities in the United States. Strong-willed individuals sought change in the late 1960s and 1970s to prevent gender discrimination in education, thus beginning the creation of the law and making it a powerful tool for women’s rights. As Title IX expanded its reach, universities have been shaped by gender discrimination in athletics, sexual assault, harassment and rape. This project outlines the evolution of Title IX through research based …

Effect Of Consistent Singing On Maintenance Of Speech Intelligibility Following Lsvt®: A Retrospective Longitudinal Case Study, Rachel Ricca Beck

Graduate Theses and Dissertations

Parkinson’s Disease is a common neurodegenerative disease affecting one’s ability to hone and refine volitional movement. Many with Parkinson’s report significant effects on voice and communication. Speech-language pathologists have long targeted the achievement of increased vocal volume through intensive voice therapy, with the most common program being Lee Silverman Voice Treatment® (LSVT®) (Ramig et al., 1994). While LSVT® is the most prominent type of voice therapy for individuals with Parkinson’s, other researchers have begun investigating therapeutic singing because of the similar functions it employs (e.g., increased breath support, utilization of entire vocal range).

The current project is a retrospective, longitudinal …

Abandoning Abuse: Acknowledging Adoption In The 21 Century, Deborah Elizabeth Ellis

Graduate Theses and Dissertations

The inspiration for this set of pieces arose from a friendship with fellow grad student Morgen Cavanah. Morgen and I were both adopted as children, and it this common background that gave rise to these pieces. The poems chosen were written by Morgen about individuals or events in her life. Though I had planned to set 9 of the original 12 poems, this set is comprised of my four favorites. Each piece uses repetitive piano motives that underlie the melodic lines of the voice, flute, and cello. This choice explores harmonic and melodic possibilities that expand minimal accompaniment. Much of …

Teaching Introductory Programming Concepts Through A Gesture-Based Interface, Lora Streeter

Graduate Theses and Dissertations

Computer programming is an integral part of a technology driven society, so there is a tremendous need to teach programming to a wider audience. One of the challenges in meeting this demand for programmers is that most traditional computer programming classes are targeted to university/college students with strong math backgrounds. To expand the computer programming workforce, we need to encourage a wider range of students to learn about programming.

The goal of this research is to design and implement a gesture-driven interface to teach computer programming to young and non-traditional students. We designed our user interface based on the feedback …

Using Cover Crops To Recycle Nutrients In An Arkansas No-Till Corn System, Kelsey Lynn Hoegenauer

Graduate Theses and Dissertations

Cover crops can provide many benefits to cropping systems including erosion control, weed suppression, and increased soil organic matter. Regardless of the intended goal for using cover crops, the changes to the nutrient flux in a cropping system caused by cover crops retaining and recycling nutrients needs to be considered in order to maximize the productivity of the following commodity crops. This research encompassed complementary greenhouse, field, and laboratory experiments to evaluate nutrient uptake and release by tillage radish (Raphanus sativus) and cereal rye (Secale cereale) cover crops, as well as the subsequent early-season recovery of recycled nutrients by the …

Geochemical Analysis Of Mississippian Cherts And Devonian-Mississippian Novaculites, Southern Midcontinent Region, Julie Mary Cains

Graduate Theses and Dissertations

This study uses trace elements and radiogenic isotopes (Pb, Sr, and Nd) to investigate the origin and mode of formation for the siliceous deposits in the Lower Mississippian Boone Formation and the Devonian-Mississippian Arkansas Novaculite in the southern midcontinent. Mississippi Valley-type Pb-Zn ore deposits in the Tri-State District and the Northern Arkansas District were deposited by hydrothermal fluids, and highly radiogenic Pb isotope ratios suggest a genetic relationship between the Boone Formation chert (206Pb/204Pb ~ 21.59, 207Pb/204Pb ~ 15.87, 208Pb/204Pb ~ 40.10) and the MVT ores. Due to the very low concentration of Pb in the Boone chert (~2 ppm) …

Shifting Abortion Attitudes Using An Empathy-Based Media Intervention: A Randomized Controlled Study, Mary Ellen Hunt

Graduate Theses and Dissertations

U.S. abortion restrictions diminish access and perpetuate a culture of hostility toward abortion seekers. Support for restrictions is high—potentially, because restriction knowledge is low and attitudes are complex. The current study focused on knowledge and support of restrictions and empathy for abortions seekers among Arkansans. The purpose was to evaluate the effectiveness of a video intervention intended to increase awareness of Arkansas abortion restrictions and induce empathy for abortion seekers.

Using a randomized controlled trial with pre-, post-, and follow-up design, a sample of Arkansans (N = 369) were randomly assigned to one of five video conditions--either a control or …

Diffuse Reflectance Spectroscopy To Quantify In Vivo Tissue Optical Properties: Applications In Human Epithelium And Subcutaneous Murine Colon Cancer, Gage Joseph Greening

Graduate Theses and Dissertations

Colorectal cancer is the 4th most common and 2nd deadliest cancer. Problems exist with predicting which patients will respond best to certain therapy regimens. Diffuse reflectance spectroscopy has been suggested as a candidate to optically monitor a patient’s early response to therapy and has been received favorably in experimentally managing other cancers such as breast and skin. In this dissertation, two diffuse reflectance spectroscopy probes were designed: one with a combined high-resolution microendoscopy modality, and one that was optimized for acquiring data from subcutaneous murine tumors. For both probes, percent errors for estimating tissue optical properties (reduced scattering coefficient and …

Master’S-Level Counseling Students’ Experience Of Expressive Arts Techniques In A Cacrep Multicultural Counseling Course, Cameron Houin

Graduate Theses and Dissertations

Counseling governing bodies have defined what should be prioritized in multicultural counseling courses, including students’ multicultural knowledge and awareness; however, best practice regarding how to teach these multicultural concepts has largely been left up to the counselor educator. Counselor educators have begun implementing expressive arts techniques in the classroom, but very little literature exists related to using such techniques in a multicultural course in a manner that positively influence counseling students’ multicultural competency.

The purpose of this study was to explore master’s-level counseling students’ experience of expressive arts techniques utilized during their multicultural counseling course. Ten student participants took part …

An Exploratory Study Of The Impact Of Acculturation On Fashion Consumption Among Hispanic Immigrants In The U.S., Laura Toloza

Graduate Theses and Dissertations

With a population of 58 million in 2016, the Hispanic immigrant population in the U.S. is expected to grow nearly 30% by 2060 (Hispanic influence, 2016). Immigrants are affected by acculturation and often have difficulty maintaining their culture of origin. Prior studies have revealed acculturation influences on consumer behaviors, but despite the increased population and purchasing power of Hispanic immigrants in the U.S., few studies have explored the ways in which acculturation influences shopping behaviors for fashion products among Hispanic consumers. The purpose of this study is to explore the general attitude related to shopping (i.e., shopping orientation) of Hispanic …

Parametric Indices Of Peer Victimization As Predictors Of Children’S Internalizing Outcomes, Freddie Aníbal Pastrana Rivera

Graduate Theses and Dissertations

Peer victimization has been linked to maladjustment in school-age children. However, the field is less clear about how different parameters of peer victimization (e.g., frequency, stability) confer risk to children. In this study, I evaluated the extent to which key parameters (operationalized as distinct peer victimization indices) predicted internalizing maladjustment in 4th grade children (N = 445). From self-, teacher-, and peer-reported victimization data gathered at three time points within an academic year, I generated the following indices: Mean Level, Stability, Cross-Informant Agreement, and Informant Source. Controlling for baseline internalizing scores, hierarchical multiple regressions indicated that: a) only self-reported Mean …

EVE Online is a massively-multiplayer online game with complex interactions between players and their unique, virtual environment. These relationships are the ongoing results of a conflict-driven economy, but they vary both in duration and by location.

This study attempts to quantify the direct effects of movement and indirect effects of conflict upon economic activity in the form of currency creation and delineate how successfully these relationships can be quantified by narrower time-spans and areas. Results of the mediation models used in this exploration indicate the changing relationship between movement (Ship Jumps), conflict (Ship Kills), and currency creation (Faction Kills) is …

Comparative Plasma Proteomics In Muscle Atrophy Induced By Cancer Cachexia And Hindlimb Unloading, Kirsten Rene Dunlap

Graduate Theses and Dissertations

Introduction: Muscle atrophy results from a dysfunction in protein turnover that leads to loss of mass and function and occurs concurrently with multiple pathologies such as cancer and extended bed rest. Atrophy reduces overall quality of life while increasing morbidity and mortality. Currently, efficacious therapeutic interventions to treat and prevent muscle wasting in all its forms are lacking, however if conserved mechanisms can be identified between wasting conditions, this would aid in the development of multipurpose therapeutics to ameliorate this pathology. Purpose: To examine circulating factors present across atrophic pathologies. Methods: 35 male C57BL/6J mice were assigned to hindlimb unloading …

Alcohol Use, Dietary, And Exercise Behaviors: A Latent Profile Analysis Of Young Adult Lifestyle Behaviors, Ryan Wesley Grant

Graduate Theses and Dissertations

As individuals enter adulthood, their lifestyles and lifestyle behaviors begin to change drastically. These lifestyle behavior changes in emerging adulthood provide a foundation for future health behaviors that often persist through all of adulthood. The aim of this study was to use Latent profile analyses (LPA) to discover distinct profiles of homogenous groups of young adults based on alcohol, diet, and exercise behaviors. Overall, five distinct profiles for both males and females were identified: Moderates, Unhealthy Eaters, Medium Drinkers, Healthier Eaters and Exercisers, and Heavy Drinkers. Heavy Drinkers and Unhealthy Eaters were the highest risk groups and reported the highest …

A Phenomenological Study Of The Lived Experiences Of Counseling Students In A Co-Facilitated Experiential Group, Alexandra Meyers

Graduate Theses and Dissertations

Research in the fields of experiential learning, group psychotherapy, and neuroscience has supported the inclusion of the experiential group in counseling training programs due to the potential for positive impact on students’ personal and professional development (Badenoch & Cox, 2010; Denninger, 2010). Investigations exploring counseling students’ experiences of the experiential group have been primarily limited to quantitative studies, while in-depth qualitative inquiry has been minimal. Additionally, an extensive review of the literature has found there have been no qualitative studies examining experiential groups co-facilitated by a course instructor and a doctoral student. The purpose of this phenomenological study was to …

Volumetric Muscle Loss: The Role Of Physical Activity And Autologous Repair On Force Recovery And Signaling Pathways, Richard Perry

Graduate Theses and Dissertations

Volumetric muscle loss affects both military and civilian persons. The hallmark of this injury is incomplete muscle regeneration, excessive fibrosis, and chronic inflammatory signaling resulting in permanent functional loss. Since permanent functional loss drastically reduces quality of life, many studies have been conducted to improve force recovery. Current scientific literature considers a repair strategy of either devitalized scaffolds infused with growth factors or viable tissue plus activating factors to be the more promising interventions for optimal force recovery. PURPOSE The purpose of this study is to incorporate autologous repair and physical activity and observe the effects of muscle force recovery …
