The Canine Genome: Discoveries, Applications, And Future Potential, Rachael Lander

Honors Theses

A frequent question that educators often encounter is: what is the value of learning? Does knowledge have an inherent value, or should there be an economic benefit? The results of the collaborative efforts to determine the nucleotide sequence of the canine genome were used as a platform to assess these thesis statements. A literature review, practical experience in the laboratory, and interviews with several genome scientists of the contributions of the efforts to determine the genome sequence of the domestic dog, and the biomedical contributions that have been made to both canine and human health demonstrate the inherent value of …

A Comparative Environmental History Of America And China: "Nature" And Climate Change, Elaine Lac

Honors Theses

Environmental history is at the most basic level an exploration of changing relationships between people and the environment or nature. Additionally, environmental history observes the human reshaping of nature, which then translates into culture, philosophies, and policies, and vice versa. A close examination of the ecological themes of history uncovers patterns and long-term changes. According to environmental historian Louis S. Warren, "At the beginning of the twenty-first century, as concerns about global warming and other ominous threats trouble many, the discipline of environmental history provides key insights into environmental relations and problems of the past." Ultimately, these insights can lead …

Approximately 18 cows were used each trial period; half being Brown Swiss and the other half being Holstein. Data was collected via CowManager ear tags, which tracked the five behavioral patterns of eating, ruminating, high, medium, and no activity. These activities served as dependent …

The Influence Of Task Specific Factors On Quantity Discrimination By Brown Capuchins (Cebus Apella) And Squirrel Monkeys (Saimiri Sciureus), Alison Rose Billas

Honors Theses

Previous studies have revealed that non-human primates discriminate quantities. However, their performance is highly variable both within and between species. Discrepancies in performance may be the result of a variety of factors, including species-specific cognitive differences or task specific factors such as representational format of the choice stimuli, motivation to perform that task, or tolerance for task delays. Six brown capuchin monkeys (Cebus apella) and six squirrel monkeys (Saimiri sciureus) were presented with two numerical quantities in three different conditions, replicating Schmitt and Fischer's (2011) study with baboons and macaques. Primates were rewarded with a quantity of food corresponding in …

Uncovering Cryptic Diversity Of Desmognathine Salamanders In The Cumberland Plateau Utilizing Molecular Genetic Techniques, Katherine E. Ray

Honors Theses

Cryptic species are difficult to identify morphologically; therefore, their distributions are often poorly understood. However, species distributions are critical for evaluating biodiversity in ecology and biodiversity. Dusky salamanders (Desmognathus) are an example of species of North American salamanders that have been particularly difficult to classify. Specifically, in the southern Cumberland Plateau, the dusky salamanders’ distributions are unknown. Desmognathus fuscus and D. conanti have been found to the north and south of the southern Cumberland Plateau, respectively. However, they have not been adequately sampled in this region. I studied genetic variation in the mitochondrial gene CytB in Desmognathus salamanders sampled from …

Redemption Of Man And Nature: Environmentalism Through The Lens Of Mainline Protestants And Conservative Evangelicals, Scottie Glen Hill

Sustainable Design: Can Eco-Friendly Be Beautiful?, Melanie T. Santiago

Honors Theses

Graphic design students and professionals experience an enormous amount of pressure in regards to their final printed pieces. In the effort to produce flawless work, they print several versions of a piece—often comparing dozens of copies for slight differences in ink variation, color saturation and paper quality. While this trial-and-error process undoubtedly accomplishes its intended effects, it also produces outrageous amounts of wasted paper, ink and cardboard among other products.

Graphic design has implemented computers to increase efficiency in the design process while ignoring the impact of obsolete hardware on the environment. In its perfectionism, it has sent countless pounds …

An Exploration Of Perseverative Behaviors In Young Children With Autism, Madison M. Ralph

Honors Theses

This study explored the interplay of stereotypical behaviors and social skills interventions in a clinical environment when stereotypy was not the focus of the interventions. A case study design was implemented to observe two participants that exhibited stereotypical and repetitive behaviors (SRBs) as well as the interventions that influenced these SRBs. Findings demonstrated prompting, positive reinforcement, and response interruption/redirection had a positive impact on shaping some SRBs but, as SRBs were not the focus of the interventions, other SRBs developed.

Using Intrinsic Properties Of Polyaniline To Sense Expression Of The Microrna Let-7, Jared N. Gloria

Honors Theses

MicroRNAs are approximately 22-nucleotide long RNA molecules that function through decay and translational repression of messenger RNA. The microRNA let-7 is found to play a role in maintaining the fate of differentiated cells in humans. Thus, expression level of this microRNA is a reliable biomarker of tumor cell phenotype. However, there are significant limitations in the current profiling techniques of microRNA. The current methods like northern blotting, microarrays, RT-PCR, or using locked nucleic acid (LNA) for in-situ hybridization are either laborious, semi-quantitative, or expensive. In this research we try to address this issue by developing a fast, specific, and inexpensive …

Functionalizing Β-Cyano Oligo(P-Phenylene Vinylene) Chromophores For Use In Mechanochromic Materials, Alexander J. Wink

Honors Theses

Mechanochromic materials are materials that change color upon mechanical deformation. This concept can be applied in areas of quality control, since the knowledge of damaged parts will easily be detected due to a color change in the material that has undergone deformation. Typically these types of materials are enabled by employing functional small molecules. Often, these are conjugated organic molecules or chromophores, which fluoresce different colors determined by the stimulus (or lack thereof) acting upon the material. In this work, we explore a new avenue to elicit color changes in polymeric materials based on the process of restriction of intramolecular …

This study utilizes the UAS-Gal4 system in order to produce a mutant phenotype capable of being visually studied and analyzed, focusing on the developmental pathway of the wing in D. melanogaster. Dissections of the wandering third instar larvae yielded wing disc tissue expressing the downregulation of loquacious and CG17386.

Robert Frost’S Ulteriority: Saying One Thing In Terms Of Another – The Inexpressible, Nicolette S. Stackhouse

Honors Theses

Robert Frost’s poetry, which is famously rich in double meaning—saying one thing but meaning something else—is also concerned with pragmatism. Pragmatism implies that there is no one fundamental universal truth. I contend that Robert Frost’s poetry says that duplicity of meaning, or ulteriority, is something to be embraced. Frost wants the uncertainty of meaning to be understood by the reader as vital to life and the mind’s processes. The simple fact that so many readers search for the hidden meanings in his poetry justly proves this point. As a pragmatist, Frost was aware that the process of getting to a …

Depictions Of The Middle Class In Magnolia Award Nominees, 2013-2015, Anna K. Rawls

Honors Theses

A flexible approach to qualitative content analysis that incorporated both deductive and inductive analysis was utilized to identify new frames, or portrayals, of middle class characters in this set of books. As a result of this analysis, several new frames of middle class characters were identified including young characters facing adult problems, being victims of teasing, and experiencing low levels of self-esteem. Additionally, a frame previously noted by Forest (2014b) that shows characters achieving upward mobility, or “rags-to-riches,” was found …

A Historical Analysis Of The Early Christian Church Fathers’ Opinions Regarding Abortion, Lauren Taylor Provencher

Honors Theses

Due to scarce material on the subject in the Bible and supposed discord among Early Christian Church Fathers, the debate on abortion is one that is often hotly contested in the United States. From the religious political aspect there is much debate over whether the Early Christian Church had a single mindset towards the notion on abortion or was deeply divided on the subject as we are today. A popular narrative, even among many in academia, is that the Church was not unified on the topic. Some even go so far as to ascribe to a pro-Choice stance on abortion …

An Evaluation Of Two Peer Literacy Strategies For The Development Of Reading Comprehension In Third Grade, Low-Income Students, Olivia L. Herring

Honors Theses

Generally speaking, low-income students fall behind their peers when it comes to reading and comprehension. Comprehension is a necessary tool for success, both in school and beyond, and must be taught effectively to these struggling students (Beirne, & Velsor, 2012). Studies have shown the benefit of student discussion and utilization of peer reading strategies in the fostering of comprehension. This study will compare students’ success after reading passages using two peer reading comprehension strategies: Paragraph Shrinking (a component of Peer-Assisted Learning) and Reciprocal Teaching. There are many questions to explore: After using both strategies, does either one encourage greater independent …

The effect of fatty acids on bacterial fitness was assessed using stress, biofilm, …

More Than A Wheelchair In The Background: A Study Of Portrayals Of Disabilities In Children's Picture Books, Sarah Caroline Crawford

Honors Theses

A review of scholarly research conducted between 2004 and 2014 revealed that portrayals of disabilities in works of children’s literature were historically poor, containing stereotypical and negative characterizations. While noting some improvements, researchers still decry a lack of balance in roles of power between characters with disabilities and those without, a lack of depth in storylines and levels of character development, and disproportionate representations of disability categories, male and female characters, and cultural minorities in comparison to the true population (Altieri, 2006; Dowker, 2004; Dyches & Prater, 2005; Dyches, Prater, & Leininger, 2009; Golos & Moses, 2011; Golos, Moses, & …

The Transfer Of Commensal And Transient Bacteria Into Deep Tissue Using Dry Needling Needles Through Agar Media Designed To Mimic The Elasticity Of Human Skin, Denisse N. Breton Guerrero

Honors Theses

Needle insertion into skin for the purpose of alleviating muscle pain began with the emergence of traditional Chinese medicinal (TCM) acupuncture. “Dry needling”, a recent alternative to acupuncture, involves inserting a monofilament needle down into the deep tissue of a patient’s skin in order to reach the affected muscle. Despite its effectiveness and low risk of infection, dry needling remains questionable with respect to its safety and the lack of research to confirm the low risk of bacterial transmission via the dry needling needles. In this microbiological study, highly concentrated Tryptic Soy Agar was utilized to simulate the elasticity of …
