Interpersonal And Ideological Kindness: A Biocultural Approach, Sally Averitt-Hubbard

Graduate Theses and Dissertations

In accordance with Richard Dawkins’ materialist “selfish gene” theory of human behavior, altruism is a subject matter that is treated conservatively by biologists, whose understanding of the human version of altruism tends toward mutualistic and sometimes reputation-based explanations of charity, kindness, and helping. Trivers (1971) first stated that non-kin altruism could evolve if altruistic behavior is balanced between partners over time, implicating a strictly mutualistic domain for kindness. But kindness herein is defined, beyond mere mutualism or reciprocity, as “the quality of being friendly, generous, and considerate.” Further, kindness tends to have an action-oriented dimension, as in Goetz et al.’s …

Therefore, the objective of this research was to develop a healthy and nutritional snack chip from germinated, Arkansas produced rough rice and germinated green gram that will be easier for the body to digest, provide much higher protein than conventional chips or crackers with low on the glycemic index, and still meet consumer demands …

The Effect Of Breakfast On Energy Metabolism, Appetite, And Food Intake In Young Versus Older Men, Allie Murphy

Human Nutrition and Hospitality Management Undergraduate Honors Theses

As life expectancy continues to rise, it is important to consider optimal nutrition recommendations to improve health outcomes, quality of life, and physical independence in older adults. Previous studies have focused on the impact of breakfast on postprandial appetite in younger adults. Research on the effects of breakfast on appetite in older adults is limited. Several studies have identified protein as a key nutrient for older adults. Protein has been shown to increase satiety for longer periods of time and decrease cravings later in the day when compared to high carbohydrate meals. However, more research is needed to determine the …

Food Localization: Empowering Community Food Systems Through The Farm Bill, Brian Albert Fink, Alexandra Oakley Schluntz, Joshua Ulan Galperin

Journal of Food Law & Policy

More diverse and value-driven public engagement has transformed the American food system. This engagement has changed the behavior of industries, consumers, policymakers, and communities. At the heart of this change is the drive among countless individuals and organizations to promote a wider variety of food choices and shape the food system in harmony with their values. Despite the local and sovereign nature of this engagement, federal food and agricultural policies have contributed substantially to this transformation of the American food system. In isolation, many of these policies support discrete programs and individuals. In the aggregate, these policies strengthen different facets …

The Rearview Mirror And Windshield: Utilizing The Intersection Of Nostalgia And Neophila To Target Today's Consumers", Hannah Lucile Hungate

Marketing Undergraduate Honors Theses

In a technologically-advanced, rapidly-changing business world, successful marketing practice is becoming more and more elusive to the competing corporations. Two popular tactics—nostalgia and neophilia—have been shown to both dazzle and destroy, depending upon their use. These concepts have been utilized by a variety of brands—some of the world’s largest beverage companies, the most popular application of 2016 and air fresheners, to name a few—and have resulted in heavy profits and losses for the companies.

Nostalgia and neophilia in marketing must first be analyzed as individual concepts, each with their own merits and disadvantages, and then viewed as an intersection where …

State Dependent Function And Dynamics In Cerebral Cortical Networks, Leila Fakhraei

Graduate Theses and Dissertations

Cerebral cortex exhibits vigorous ongoing, internal neural activity even with no sensory input is present or the animal is minimally engaged in a task or behavior. This internal ongoing activity is not static; the ‘cortical state’ varies ranging from synchronous and highly correlated activity to asynchronous and weakly correlated neural activity. The main goal of the work presented here is to understand how changes in cortical states effect several aspects of cortical function and dynamics.

To meet this goal, we did three separate projects. First, we compared the predictability of neuronal network dynamics across cortical states in somatosensory cortex of …

Pynchon And Place: A Geocritical Reading Of Thomas Pynchon, John Stout

Graduate Theses and Dissertations

A special emphasis on artificial or constructed spaces appears throughout Thomas Pynchon’s body of work. This thesis explores how Pynchon describes such spaces and their uses to address such weighty topics as social inequity and the struggle against authoritarianism. In examining the role of sheltering spaces in novels such as V. and Gravity’s Rainbow, I argue that Pynchon depicts various “outsider” characters as finding reification of their own forms of alterity within spaces either designed or co-opted with such purpose in mind. Through Pynchon’s depiction of spatial transformation in novels like Vineland and Inherent Vice, the author finds the opportunity …

Zinc Injection As A Novel Castration Method And Carry-Over Effects Of Growth-Promoting Implants In Beef Cattle, Jase Joseph Ball

Graduate Theses and Dissertations

In experiment 1, crossbred bull calves (n = 31; body weight (BW) = 114.3 ± 26.3 kg; age = 119 ± 18.4 d) were allocated to treatments by BW and birthdate. Twenty-seven bull calves were allocated to 3 injectable castration treatments (n = 9 calves/injectable castration treatment) to reflect 3 dosage levels of zinc. Intact bulls had greater (P < 0.001) serum testosterone concentrations compared to bulls injected with zinc. In experiment 2, crossbred beef bulls (n = 180) were blocked by initial BW (337 ± 10.9 kg; 6 blocks) and assigned randomly to 1 of 3 treatments on d 0: 1) INJ; received 1 mL (100 mg Zn) of a Zn solution in each testis, 2) BAN; banded, 3) BUL; intact. Final BW was greater (P < 0.01) for INJ (672 kg) and BUL (686 kg) compared to BAN (611 kg). Serum haptoglobin concentration was greater (P < 0.01) in INJ compared to BUL and BAN on d 1, 3, 5, and 7. Zinc injection resulted in sterilization but not castration in feedlot bulls although it was efficacious in castration of young bulls at branding. In experiment 3, crossbred beef steers (n = 106; BW = 96 ± 3.9 kg; age = 74 ± 2.0 d) were blocked by parity of dam (≤ 2 or > 2 parities), stratified by BW, calf age, calf sire, cow BW and body condition score to 1 of 4 treatments: 1) RALG, Ralgro, Ralgro, Revalor XS, at branding (D 0), weaning (D 156), and feedlot processing (D 325), 2) COMP, Component …

Antiproliferative Activity Of Carotenoids, Phenolic Compounds, And Volatile Terpenoids In Carrots (Daucus Carota L.), Brittany Frederick

Graduate Theses and Dissertations

Epidemiological studies have shown an association between high carrot consumption and low prevalence of cancer. This observation has been thought to be attributed to carrot carotenoids. Despite this, various intervention trials have displayed no changes in incidence or increased incidence of cancer with carotenoid supplementation. It is possible that carrot phenolics are responsible for this association, though this has not been widely accepted. Volatile terpenoids from carrots have not been studied in this regard. Therefore, the primary objective of this study was to compare the antiproliferative effects of carotenoids, phenolics, and volatile terpenoids extracted from carrots on Caco-2 colon cancer …

A Proposed Approach To Hybrid Software-Hardware Application Design For Enhanced Application Performance, Alex Shipman

Graduate Theses and Dissertations

One important aspect of many commercial computer systems is their performance; therefore, system designers seek to improve the performance next-generation systems with respect to previous generations. This could mean improved computational performance, reduced power consumption leading to better battery life in mobile devices, smaller form factors, or improvements in many areas. In terms of increased system speed and computation performance, processor manufacturers have been able to increase the clock frequency of processors up to a point, but now it is more common to seek performance gains through increased parallelism (such as a processor having more processor cores on a single …

Examining The Appropriate Recovery Interval Following Maximal Exertion For Baseline Computerized Neurocognitive Testing (Cnt), Samantha Mohler

Graduate Theses and Dissertations

Background: Computerized neurocognitive testing is part of the recommended multi-faceted approach to SRC assessment. Prior research has suggested that maximal exertion negatively effects CNT test scores. Purpose: To identify the appropriate timing of the administration of CNT following maximal exertion in healthy college-aged students. Study Design: Random cross-over, repeated measures design. Methods: Participants will be administered CNT on four different visits, with at least one week between administrations. A VO2 max treadmill test will be performed before CNT administration during three of the four trials. Following the VO2 max test, participants will rest for <2 minutes (immediate), 10-minutes, or 20-minutes before taking CNT. The fourth trial, without maximal exertion preceding CNT administration, will serve as the control. All trials will be randomly-counterbalanced to negate practice effects. RESULTS: There was a significant within-subjects effect for prescribed post-exertion recovery intervals on total symptom scores (Wilks λ = .62, F [3, 23] = 4.64, p = .01, η2= .38). Total symptom scores were significantly higher at the immediate (p < .002), 10-minutes (p = .018), and 20-minutes (p = .011) post-exertion recovery intervals compared to baseline. Additionally, a significantly positive within-subjects effect for prescribed post exertion recovery was observed for processing speed (p=.009, Wilks λ = .60, F [3, 27] = 5.9, η2 = .396). No significant effect was observed for visual memory (p = .07), verbal memory (p = .06), or reaction time (p = .40). CONCLUSION: Baseline symptom scores were negatively influenced processing speed was enhanced by maximal exertion. These changes continue to be elevated 20 minutes post-exertion. Moreover, cognitive performance was not significantly impaired following maximal exercise. To obtain more accurate baseline symptom scores, and allow processing speed composites to return to normal, sports medicine professionals should wait at least 20 minutes following maximal exertion before administering CNT.

A Flourynge Aege: Tracing The Sacred And Secular In The Book Of St. Albans, Allison Treese

Graduate Theses and Dissertations

With the introduction of the printing press to England around the mid-fifteenth century, English authors were not only writing under the lingering influence of Chaucer and the conventions of established medieval genres, but now had to confront the implications for reading and readership that printing brought with it along with the already turbulent political climate of the fifteenth century. Though this cultural shift was arguably a gradual one, with the earliest printers taking special care to remain faithful to the manuscripts they were copying, and conventional scribes likewise being commissioned to make copies of printed works, there were nevertheless radical …

Factors Affecting The Longevity Of Individual Terrorists, Madeline Brice

Graduate Theses and Dissertations

The purpose of this study is to examine factors that affect the longevity of individual terrorists. Previous studies on terrorist group longevity have focused on the decisions terrorist groups have made rather than focusing on factors that help individuals evade capture. Literature also suggests that terrorists that manage to stay active may be able to use this as a valuable recruiting tool. This project examines six different relationships with longevity, including Attorney General (AG) Guidelines, demographics, ideology, level of participation, number of activities, and sophistication of attack. To examine these relationships, data will be used from the American Terrorism Study …

Experimental And Model-Based Terahertz Imaging And Spectroscopy For Mice, Human, And Phantom Breast Cancer Tissues, Tyler Bowman

Graduate Theses and Dissertations

The goal of this work is to investigate terahertz technology for assessing the surgical margins of breast tumors through electromagnetic modeling and terahertz experiments. The measurements were conducted using a pulsed terahertz system that provides time and frequency domain signals. Three types of breast tissues were investigated in this work. The first was formalin-fixed, paraffin-embedded tissues from human infiltrating ductal and lobular carcinomas. The second was human tumors excised within 24-hours of lumpectomy or mastectomy surgeries. The third was xenograft and transgenic mice breast cancer tumors grown in a controlled laboratory environment to achieve more data for statistical analysis.

Development Of Microdialysis Probes In Series Approach Toward Eliminating Microdialysis Sampling Calibration: Miniaturization Into A Pdms Microfluidic Device, Randy Espinal Cabrera

Graduate Theses and Dissertations

A new microdialysis sampling method and microfluidic device were developed in vitro. The method consisted of using up to four microdialysis sampling probes connected in series to evaluate the relative recovery (RR) of different model solutes methyl orange, fluorescein isothiocyanate (FITC)-dextran average mol. wt. 4,000 (FITC-4), FITC-10, FITC-20, and FITC-40. Different flow rates (0.8, 1.0, and 1.5 µL/min) were used to compare experimentally observed relative recoveries with theoretical estimations. With increasing the number of probes in series, the relative recovery increases and ~100% (99.7% ± 0.9%) relative recovery for methyl orange was obtained. For larger molecules such as fluorescein isothiocyanate …

In Vivo Structure-Function Analysis Of Drosophila Robo1, An Axon Guidance Receptor Critical For Midline Repulsive Signaling In The Embryonic Central Nervous System, Haley Brown

Graduate Theses and Dissertations

The repellant ligand Slit and its Roundabout (Robo) family receptors regulate many aspects of axon guidance in bilaterians, including midline crossing of axons during development of the embryonic CNS. Slit proteins are produced by midline cells and signal through Robo receptors expressed on the surface of axonal growth cones to repel axons from the midline. Disruption of Slit-Robo signaling causes ectopic midline crossing phenotypes in the CNS of a broad range of animals, including insects and vertebrates.

Drosophila Robo1 has a conserved ectodomain structure of five immunoglobulin-like (Ig) domains plus three fibronectin (FN) repeats. By utilizing a genomic rescue construct …

Transformational Leadership In Club Sports: An Instrument For Evaluation And Assessment, Nathan Shelby Hutchens

Graduate Theses and Dissertations

Campus Recreation and its programs can be used as a way to combat the national trends of decreasing enrollment and retention (Weaver, Forte, & McFadden, 2017; Kampf & Teske, 2013). In fact, 62% of students indicate that Campus Recreation programs are a factor when choosing an institution and 67% indicate that recreation programs were a factor when deciding to stay at a particular institution (Forrester, 2014). As a program within Campus Recreation, Club Sports specifically is perceived to have the greatest health and wellbeing benefits out of all Campus Recreation programming (Lower, Turner, & Petersen, 2013). Due to the voluntary …

The Effect Of Cellular Dehydration On Glucose Regulation In Lean And Obese Females, Chunbo Yang

Graduate Theses and Dissertations

A chronically elevated vasopressin level has been associated with an impaired glucose regulation system in humans. A recent study in patients with diabetes suggested that low water intake is associated with impaired glucose regulation. The aim of this study was to examine the effect of hypertonic saline infusion on glucose regulation in healthy females. Thirty healthy, non-diabetic females performed a 2-h infusion followed by a 4-h oral glucose tolerance test (OGTT). Every subject participated in two trials separated by one month, in a counterbalanced order. Two trials were identical in the procedure, differing in the concentration of saline infusion, with …

Evaluation Of The Effects Of Formaldehyde On Growth Parameters Of Broiler Chicks, Paula Johnson

Graduate Theses and Dissertations

Formaldehyde has been used as a disinfectant in poultry hatching cabinets to aid in controlling key pathogenic organisms, such as Salmonella and Escherichia coli (E.coli). There is some evidence that prolonged exposure of chicks to formaldehyde can reduce tracheal ciliary function and thus reasons to believe that exposure to formaldehyde, in the absence of pathogen challenge, may reduce chick vitality. It has been found that elevated temperatures during incubation may adversely affect body weights of broiler chicks, as well as post-hatch environmental heat stress on performance in poultry. Post-hatch environmental heat stress has been shown to impact performance in poultry. …

The End Of Want, Anthony Blake

Graduate Theses and Dissertations

The poems of The End of Want are attuned to the absurdities of modern existence. They take as their jumping-off points the various offbeat occasions that punctuate our lives: over-researched time spent in art museums, Kevin James sitcoms, half-finished cathedrals, and suburban communal living. They catalog the emptiness of what we say to each other and the increasingly disconnected ways we say it. All the while, with dry humor and heart, they search out, and try to hold onto, moments of transcendence amongst corporate language and new definitions of masculinity, and humanity, and holiness.

The Vaginal Microbiome Related To Reproductive Traits In Beef Heifers, Maryanna Wells Mcclure

Graduate Theses and Dissertations

The greatest impact on profitability of a commercial beef operation is reproduction. In the human vaginal microbiome, dominance by Lactobacillus is a sign of reproductive health and fitness. In other species (non-human primates and ewes), Lactobacillus is found in low amounts and dominators of these microbial communities are considered to be pathogenic in humans. In beef heifers, little is known about the vaginal and fecal microbiota with respect to their relationship with fertility. To this end, we followed heifers through gestation to examine the dynamics of vaginal and fecal microbial composition throughout pregnancy.

Heifers were exposed to an estrus synchronization …

“The Commercial Union Of The Three Americas:” Major Edward A. Burke And Transnational New South Visionaries, 1870-1928, Michael Powers

Graduate Theses and Dissertations

Traditional images of the late nineteenth and early twentieth-century American South are of an inward-looking region characterized by economic stagnation, xenophobia, cultural isolation, and reactionary politics. This dissertation contends that vibrant transnational links connected the South to the wider world through an analysis of the political and economic landscape of postbellum Louisiana, the 1884 New Orleans World’s Industrial and Cotton Centennial, the Louisiana State Lottery Company, and Central America. An examination of Edward Austin Burke demonstrates that the era’s New South creed comprised a seminal transnational component.

This dissertation will explore how Burke became a central cog in Louisiana’s Democratic …

Computational Fluid Dynamics Model For Air Velocity Through A Poultry Transport Trailer In A Holding Shed, Christian Heymsfield

Graduate Theses and Dissertations

Broiler production in Arkansas was valued at over $3.6 billion in 2013 (University of Arkansas Division of Agriculture Cooperative Extension Service). Consequently, improvement in any phase of the production process can have significant economic impact and animal welfare implications. One area of concern for the poultry industry is thermal stress experienced by the birds after arrival at the processing plant and before they are taken in to be processed, during which time they are left to wait in holding sheds. Various cooling strategies exist to mitigate heat stress in holding sheds, but in most cases it is unlikely that they …

Defending Wild Dogs: Population Dynamics And Disease In Endangered African Wild Dogs, Elizabeth Claire Arredondo

Graduate Theses and Dissertations

African wild dogs (Lycaon pictus) are endangered carnivores whose population is decreasing from habitat loss and fragmentation, interspecific competition, and disease. Survival rates are especially low in Kruger National Park (KNP), though it is unclear why. I estimated the abundance in KNP and survival rates over different time spans, six years and nine months, using public photographic survey data. In 2015, there were 298 (SE=12.1) individuals. Using a mark-recapture analysis in program R, I found that the survival rate between 2009-2015 was only 3.2%, and within the 9-month survey period (September 2014 – June 2015), monthly survival rates for the …
