An Introductory Educational Board Game For Use In Early Computer Science Education, Tyler Moore

Computer Science and Computer Engineering Undergraduate Honors Theses

Early computer science education should be necessary in high school curricula, but often it becomes inextricably linked to the act of programming instead of the study of the principles of computation. In order to divest computer science from programming a new teaching medium is needed, and early research into games as teaching tools shows some positive results when used properly. In order to find a better way to teach early computer science concepts I have designed and implemented a board game which illustrates and defines a few necessary computer science terms and mechanics. I had reasonable success in the classroom, …

The Role Of Albino3 And The Lipid Environment In Chloroplast Signal Recognition Particle Targeting, Nathan Lewis

Graduate Theses and Dissertations

Signal recognition particles (SRPs) in pro- and eukaryotes function in cotranslational targeting of nascent poplypeptides to an SRP receptor at the target membrane. A unique chloroplast SRP (cpSRP) functions post-translationally to direct light-harvesting chlorophyll-binding proteins (LHCPs) to the receptor cpFtsY at the thylakoid membrane for LHCP insertion in a process involving the integral membrane protein Albino3 (Alb3) and requiring GTP. Work here focuses on understanding cpSRP targeting events at the thylakoid membrane, specifically those involving Alb3 and the lipid environment.

We show an interaction between the novel cpSRP subunit cpSRP43 and the soluble, stromal-exposed C terminus of Albino3 (Alb3-Cterm). We …

The Antimicrobial Activity Of Cold Pressed Terpeneless Valencia Orange Oil At Cold Temperatures, Sean Jeffrey Pendleton

Graduate Theses and Dissertations

This research was undertaken to identify an antimicrobial for use during chilling in beef processing, including periods of temperature abuse, as well as to evaluate membrane filtration as means to remove essential oils from bacteria to prevent further antibacterial action. Cold pressed terpeneless Valencia orange oil was examined in combination with various temperatures (37°C, 10°C, and 4°C) to determine its antimicrobial activity against various strains of bacteria. The strains were tested using a ninety-six well microtiter plate method, with or without membrane filtration. The compound 2, 3, 5-triphenyl tetrazolium chloride was used as a growth indicator. Serial, two fold dilutions …

An Empirical Investigation Of Emotional Reactivity And Elevated Mental Contamination: A Comparison Of Sexual And Physical Assault, Christal Badour

Graduate Theses and Dissertations

Although evidence suggests that disgust and disgust-related phenomena such as mental contamination should be associated with the experience of sexual assault, there has been relatively little direct examination of this relation. Consequently, the primary aim of the current study was to conduct a multimodal assessment of disgust and mental contamination-based reactivity to an individualized script-driven imagery procedure. Participants included 27 sexually assaulted, 25 physically assaulted, and 30 non-traumatized control female adults. Subjective reactivity (i.e., ratings of disgust, anxiety, feelings of dirtiness, and urges to wash), physiological reactivity (i.e., electromyogram activity of the right levator labii superioris and medial frontalis regions) …

Modern Day Utopia: An Examination Of Internal Social Control Among "Rainbow Family", Ashleigh Elain Mckinzie

Graduate Theses and Dissertations

This thesis employs ethnographic fieldwork and interviews to examine internal Social control, ideological embeddedness, and resistance to mainstream culture and ideology in a utopian, counter-cultural group called The Rainbow Family of Living Light. Combining theoretical perspectives on emotions and re-integrative and dis-integrative shaming with symbolic interaction, I examine the experiences of Rainbow during a national Gathering in the summer of 2010. Through interviews and observations, I illustrate the rituals, organization of camp, stratification based on work, and solidarity building activities, that Rainbow Gatherers create to resist mainstream ideology and culture. Further, I show that they Rainbow Gatherers redefine deviance in …

An Ecology Of Philanthropy: Community Composition And Nonprofit Revenue In The United States, Wendie Neesa Choudary

Graduate Theses and Dissertations

There is little doubt that most American cities are currently troubled places because of massive economic shifts that have marked the last two decades. Charitable giving has consistently been seen as the lifeblood of communities around the United States (Backman and Smith 2000). The primary purpose of this study is to examine the relationship between community composition and charitable giving. The impact of community characteristics (community composition, organizational composition, and community deterioration) on charitable revenues will be assessed using revenue data from the 2006-2007, 501(c)(3), 990, charitable organization forms along with United States county census data. One-way ANOVA and regression …

The Effects Of Ovariecotomy On Neuropeptide Y Neurotransmission In Skeletal Muscle Arterioles, Kirk Wendell Evanson

Graduate Theses and Dissertations

The purpose of this study was to determine the effects of chronic estrogen supplementation on NPY neurotransmission in gastrocnemius first-order arterioles (G1A) of adult female rats. Female rats (4 mo; n = 30) were ovariectomized (OVX) with a subset (n = 15) receiving an estrogen pellet (OVE; 17β-estradiol (4μg / day)). Following conclusion of the treatment phase (8 weeks), red G1A were excised, placed in a physiological saline solution (PSS) bath, and cannulated with micropipettes connected to albumin reservoirs. A sampling port was placed immediately below the vessel to assess NPY overflow. The contralateral red G1A was homogenized in PSS …

Characterization Of Polyphenolics In Cranberry Juice And Co-Products, Brittany Lynn White

Graduate Theses and Dissertations

Historically, cranberry juice has been consumed to prevent urinary tract infections. These and other health benefits, including reduced risks of cancer and cardiovascular disease, are believed to be due to the presence of polyphenolics, specifically flavonoids. Cranberry pomace is the by-product of cranberry processing which consists of seeds and skins. This research focuses primarily on the effects of processing on the flavonoid composition of cranberries and cranberry pomace. First, the concentration of flavonoids during juice processing was evaluated. It was determined that anthocyanins were degraded readily compared to other flavonoids, and a significant amount of flavonoids were retained in the …

Biodiesel Production From Waste Algae Through Supercritical Methanol And Solid Catalysts, Alexander Lopez

Chemical Engineering Undergraduate Honors Theses

The need for alternate fuels continues to rise as fossil fuel reserves decline, and the effects of harmful fuel emissions on the environment begin to take its toll. One alternate fuel that has great potential is biodiesel. Biodiesel is a non-petroleum based fuel composed of alkyl esters from feedstocks. Using biodiesel as an alternate fuel source has a variety of advantages over traditional petroleum diesel, including producing no SOx emissions and low COx emissions. Another important advantage of biodiesel is that it can be produced from a wide variety of feedstocks. Biodiesel processes using waste cooking oil, animal fats, and …

Getting Into The Field, Jay A. Mitchell

Journal of Food Law & Policy

A group of students enrolled in a law school clinic wanders through a large farmers' market. They stop to chat with the proprietors of a farm that has sold vegetables at the market for many years. They visit with a cheesemaker and an apple grower. A second group learns about the economic costs of organic production from a farmer and talks with an olive oil producer. Both sets of students seem unusually attentive to their surroundings. That may be because the first group helped the sponsor of the market rework the market's rules and regulations, and the second developed a …

Food Entrepreneurs And Food Safety Regulation, Nina W. Tarr

Journal of Food Law & Policy

It is a bucolic scene: local food growers and producers chatting with consumers who come back each week to participate in a direct and continuing conversation about food with someone they know, and to engage in commerce. This illusion of simplicity masks the ever-growing morass of conflicting, complicated, and expensive regulatory oversight that undermines the local food movement by creating barriers between producers and consumers. Those creating and implementing food policy in the United States are facing a fundamental dilemma of how to reconcile the local food movement with regulations designed to address concerns about food safety.

This article will …

The History And Future Of Genetically Modified Crops: Frankenfoods, Superweeds, And The Developing World, Brooke Glass-O'Shea

Journal of Food Law & Policy

In a 1992 letter to the New York Times, a man named Paul Lewis referred to genetically modified (GM) crops as "Frankenfood," and wryly suggested it might be "time to gather the villagers, light some torches and head to the castle." Little did Lewis know that his neologism would become the rallying cry for activists around the world protesting the dangers of genetic engineering. The environmental activist group Greenpeace made great use of the "Frankenfood" epithet in their anti-GM campaigns of the 1990s, though they have since backed away from the word and the hardline stance it represents. But genetically …

Analysis Of Rice Blast Resistance Genes In The National Small Grains Collection (Nsgc), Moytri Roychowdhury

Graduate Theses and Dissertations

Identification of blast resistance genes in rice germplasm is one of the most important activities of rice breeding programs in worldwide. The objective of this research was to characterize two major blast resistance genes, Pi-z and Pi-b, in selected rice germplasm. A simple sequence repeat DNA marker, AP5659-1 linked to the Pi-z gene, and a Pib dominant marker derived from the Pi-b gene were first used to screen a rice core collection consisting of 1700 accessions estimated to represent 70% of the genetic diversity of rice in the US National Small Grains Collection. There were 131 rice germplasm accessions with …

United States Food Law Update: The Fda Food Safety Modernization Act, Obesity And Deceptive Labeling Enforcement, A. Bryan Endres, Nicholas R. Johnson

Journal of Food Law & Policy

The long-awaited enactment of the FDA Food Safety Modernization Act (FSMA), the most significant amendment to the Federal Food, Drug, and Cosmetic Act in several decades, provides the Food and Drug Administration (FDA) with significantly enhanced jurisdiction to close some of the gaps in the domestic food safety system. The enhanced FDA authority, however, will have little impact on the shared governance system at the federal level that involves multiple agencies, as the Act does not address the U.S. General Accounting Office's (GAO) repeated calls for consolidation of the fragmented federal food safety system. Rather, the Act perpetuates the division …

Innovation And Development Of Biofuel Technologies, Nicole Lorenz

Chemical Engineering Undergraduate Honors Theses

The need for viable alternatives to gasoline has lead researchers to explore various options for renewable energy resources. This research study focuses on two major options for renewable energy. The first is biodiesel, which is a fuel that can be made from vegetable oils or animal fats. In this study, biodiesel was made from tall oil, a paper byproduct. A novel reaction method was used, employing high temperature methanol rather than acid or base catalysis. The second option that was investigated is butanol, which is an alcohol with advantages over ethanol. First, a two-step fermentation was examined to improve the …

Dietary And Behavioral Strategies Of Neandertals And Anatomically Modern Humans: Evidence From Anterior Dental Microwear Texture Analysis, Kristin Lynn Krueger

Graduate Theses and Dissertations

The extreme gross wear of Neandertal anterior teeth has been a topic of debate for decades. Several ideas have been proposed, including the excessive mastication of grit-laden foods and non-dietary anterior tooth use, or using the anterior dentition as a clamp or tool. This second idea has been the most examined, and was taken from analogy of Arctic populations who used their anterior dentition in this manner. However, combining wear variables and examining them in relation to important factors, such as climate, location, and time, has been challenging to incorporate into interpretive models. The present study seeks to better understand …

Stealth Carbon Nanotubes: Strategies To Coat Carbon Nanotubes To Prevent Opsonization And Improve Biodistribution, Nalinikanth Kotagiri

Graduate Theses and Dissertations

Carbon nanotubes (CNT) have recently been in the limelight for its potential role in disease diagnostics and therapeutics. Even before these medical applications can be realized, there is a need to address issues like opsonization, phagocytosis by macrophages and sequestration to liver and spleen for eventual elimination from the body. We believe coating CNT with biocompatible and opsonin resistant moieties will not only help CNT in traversing the blood stream to reach the target organ, but also improve biodistribution tremendously. We set out to achieve this by firstly identifying a new compound, mAmp, which is a fluorescent derivative of the …

(Re)Constituting The Immigrant Body Through Policy: A Rhetorical Analysis Of The Narratives Within The Discourses Of The Development, Relief, And Education For Alien Minors Act (Dream Act), Emily Rae Ironside

Graduate Theses and Dissertations

Using the testimonies surrounding the Development, Relief, and Education for Alien Minors Act (DREAM Act) as a primary case study, this project provides a rhetorical investigation of the interplay between narratives, nation building, national identity, policymaking, and the American immigrant. This project first identifies the grand narrative of exclusionary nationalism as the primary narrative constituting the American identity. Then, this project examines the rhetoric of policymakers to demonstrate how an Anglo-Saxonized, elitist notion of American identity is rhetorically constituted by assimilationist, racist, xenophobic, and classist discourses. Moreover, it argues policymakers maintain the narrative dominance of exclusionary nationalism through restrictive immigration …

Application Of Existing Appropriate Technology To Small Communities In Honduras's Opalaca Mountains, Adrian Beirise

Mechanical Engineering Undergraduate Honors Theses

In a 2009 trip to the Opalaca Mountain region of Honduras, a need was identified for appropriate technology solutions to three key issues: housing improvements related to Chaga's Disease, indoor smoke reduction, and pure water. Through research regarding the problems, the local area, and candidate solutions, a set of three solutions was found. This includes corrugated steel roofing, vented or simple adobe rocket stoves, and solar disinfection.

Mitigation Of Bovine Respiratory Disease Complex: Interactions Of Physiology, Immunology, Nutrition And Management, John Thomas Richeson

Graduate Theses and Dissertations

A series of experiments were conducted to determine the effects of on-arrival vs. delayed respiratory vaccination and exposure to persistently infected bovine viral diarrhea virus challenge on health, gain performance, and physiological and immunological measurements in newly received stocker cattle. Two experiments evaluated timing (d 0 vs. 14) of respiratory, clostridial, or both vaccinations in newly received stocker calves during stress-induced immunosuppression. In Exp. 1, calves receiving 14-d delayed vaccination of a pentavalent modified-live respiratory virus (MLV) vaccine had greater ADG during the 42-d receiving period and antibody titers against infectious bovine rhinotracheitis on d 42; however, morbidity rate did …

Reactivation Of Negated Concepts Over Time, Kevin Autry

Graduate Theses and Dissertations

Research on the mental representation of negated concepts in written texts has yet to reach a consensus about the effects of negation. MacDonald and Just (1989) reported that after reading a sentence with a negation, negated words took longer to recognize than non-negated words, which suggests that the negated concepts became less active. However, Hasson and Glucksberg (2006) found that after reading negative metaphors (e.g., This surgeon isn't a butcher), lexical decisions about words consistent with the affirmative sense of the negated word (e.g., clumsy) took less time than for control words. To reconcile these (and other) incompatible findings, two …

Southern Exceptionalism And Its Impact On Environmental Attitude, Summer Dawn Woehr

Graduate Theses and Dissertations

In recent years, the environment has become a top concern for many people. Scientific studies have shown evidence of immediate and future threats on our environment. Despite the vast amount of evidence, many people (especially in the South) do not believe there is a human cause for global warming, a fundamental part of the environmental movement. Literature suggests Southern exceptionalism may a play a part in shaping attitudes toward environmental policies in the South. Further, a recent look at V.O. Key Jr.'s 1949 Southern Politics in State and Nation suggests that religion has since been overlooked as an explanation for …
