Characterizing The Host Usage And Development Of Ormia Lineifrons (Diptera: Tachinidae), Kyler J. Rogers

Murray State Theses and Dissertations

Insect communication systems are strongly driven by the evolution of signals or signal preferences. These systems rely on a signaler to truthfully emit signals for receivers to interpret. Often, these signals are conspicuously broadcasted. Conspicuous signals involved in animal communication are intended to attract mates, however, these signals are often exploited by eavesdroppers. Thus, many communication systems experience natural selection and sexual selection acting in opposite directions. New adaptations can arise in response to selective pressures, such as eavesdroppers, leading to co-evolving systems between eavesdroppers and hosts, for example. Understanding these systems can provide valuable insight into how unintended receivers …

An Investigation Into Cte Classroom Instructional Strategies, Jonathan Walker

Murray State Theses and Dissertations

This researcher conducted this ex post facto study with the help of career and technical education (CTE) teachers across the country. The research was a survey of classroom instructional strategy usage, a teacher’s familial impact on classroom instruction strategies used, and the effects of Covid-19 on classroom strategies used. Data suggested that CTE teachers use different instructional strategies based on teacher demographics and that Covid-19 did have an effect on CTE teachers’ use of instructional strategies. This data suggested the five most used classroom instructional strategies were questioning, guided practice, demonstrations, lab activities, and whole group discussion.

Glial Granules And Germline Proteins In The Drosophila Brain, Samuel J. Tindell

Murray State Theses and Dissertations

My overarching goal was to elucidate the role of Tudor (Tud) protein in the Drosophila brain. Tud is an evolutionarily conserved molecular scaffold, containing 11 Tud domains which bind to symmetrically dimethylated arginine (sDMA) residues in a variety of proteins. Tud is an essential component of embryonic ribonucleoprotein complexes (RNPs) called germ granules that contain RNAs and proteins crucial to the differentiation and maintenance of germ cells, the specialized class of stem cells that ultimately give rise to the next generation of organism. In the absence of Tud, there is a complete abolishment of germ cells highlighting its important role …

Perceptions Of Covid-19, Information Seeking Behavior, And Political Orientation, Bailey Dodd, Sean Rife

Murray State Theses and Dissertations

COVID-19 was declared an international pandemic in March 2020 and infected millions of people globally in less than six months. Research suggests that a large amount of both accurate and misinformation exists on the pandemic, and it would be expected that an individual’s political orientation would influence their perception of the virus and the information that they endorse. Based on past research, it would be expected that both liberals and conservatives would be equally concerned about the COVID-19 pandemic and endorse similar measures. However, Republicans downplayed the pandemic and were more likely to consider it a hoax, while Democrats exaggerated …

The Reconstruction Of Hatchery Creek: Effects On Macroinvertebrate And Fish Community Dynamics, Patrick Vrablik

Murray State Theses and Dissertations

Hatchery Creek is a restored stream in Jamestown, KY that drains Wolf Creek National Fish Hatchery. The previous degraded channel of Hatchery Creek caused large sediment plumes in the Lower Cumberland River and was restored to decrease sediment loss and provide the opportunity for a self-sustaining trout population. I predicted that the increased amount of habitat would increase taxa richness, abundance and biomass of macroinvertebrates. Macroinvertebrates were monitored in three periods; the degraded period, a one-year recovery period, and a restored period using surber and kicknet samples in order to determine biomass, abundance, diversity, taxa richness, and macroinvertebrate biotic index. …

Generational Giving In Public Higher Education, Christine Bernot

Murray State Theses and Dissertations

Abstract

Competition for donors and dollars between higher education and the non-profit sector has never been greater, with Americans giving nearly $450 billion in philanthropic support to charitable organizations in 2019 (IUPUI, 2020). Alumni of higher education institutions are a natural constituency group with a history of giving back to support student needs and programs.

New research in fundraising for higher education analyzing generational giving behaviors of alumni graduate donors could help universities better understand their giving results and support the innovation of new fundraising strategies and best practices. This quantitative research study used historical giving data to examine the …

The Effects Of Reinforcement Sensitivity And Effortful Control On Anhedonia And Valued Living, Houston Howard

Murray State Theses and Dissertations

Research has begun to uncover how individual temperamental and self-regulatory differences relate to certain psychopathological symptoms. Specifically, the current literature is expanding the view of how anhedonia, effortful control (EC), and reinforcement sensitivity may relate to one other. The aim of this study was to examine these relationships and explore models that might explain how these variables interact to predict valued living. Specifically, it was hypothesized that 1) greater anhedonia would be associated with lower levels of valued living, 2) the behavioral activation system (BAS) would moderate the effect that anhedonia has on valued living by decreasing its impact, with …

Murray State Theses and Dissertations

This study addresses the controversial diagnosis of childhood apraxia of speech (CAS) and the struggle many clinicians face with differential diagnosis through a retrospective qualitative case study following a participant who received the diagnosis of CAS. Research questions targeted the characteristics the participant presented with, whether they were consistent or not, as well as if they were unique to CAS or evidence of a phonological disorder, and the treatment approaches that were implemented throughout the participant’s history of receiving speech-language services and the effectiveness of those approaches. These research questions were answered through the records and documents obtained from the …

Can It Be Done? Examining Stereotype Threat With Fake Stereotypes, Jessica Hodges

Murray State Theses and Dissertations

Stereotype threat refers to the risk of conforming to a stereotype regarding a group one belongs to. This threat has been heavily studied with negative stereotypes on performance-based tasks (e.g., math), and encompasses the anxiety one may feel due to being associated with the negative stereotype (Steele & Aronson, 1995). The present project sought to expand upon current literature in several ways. First, this project sought to assess whether fake stereotypes elicit stereotype threat like real stereotypes do. Second, this project examined whether fake stereotype threat works with positive stereotypes as well as negative. Third, this study examined how group …

Intrahistiocytic Storage Of Clofazimine Crystals In A Cat, Nathan D. Helgert, Debra L. Miller, Jacqueline C. Whittemore, Mee-Ja M. Sula

Faculty & Staff Research and Creative Activity

A 13-year-old castrated male Maine coon cat with a 5-year history of atypical mycobacteriosis was euthanized and submitted for necropsy. The cat had been kept in clinical remission since diagnosis using a combination of the antimycobacterial drug clofazimine and additional multimodal antimicrobial therapy. Grossly, tissues were diffusely discolored red-brown to yellow. Histologically, the myocardial interstitum was expanded by numerous, often multinucleated cells, which were distended by uniformly shaped acicular cytoplasmic spaces. These cells were immunopositive for CD18 and immunonegative for desmin, suggesting a histiocytic rather than muscular origin. Macrophages in other tissues contained similar acicular spaces. Ultrastructurally, the spaces were …

The Effects Of Music On Dairy Production, Anneliese Kemp

Honors College Theses

The purpose of this research is to find which genre of music dairy cows produce the most milk to in order to aid dairy farmers in yielding maximum product while also keeping their cattle as comfortable as possible. During each lactation a different genre of music will play, basic vital signs, and behavioral observations of the cows will be taken, then the amount of milk produced during that genre will be measured. First, no music will be played, base line vitals will be taken, and milk yield will be measured. This will give an estimate to how positively or negatively …

Grim Under A Compensation Variant, Aaron Davis, Aaron Davis

Honors College Theses

Games on graphs are a well studied subset of combinatorial games. Balance and strategies for winning are often looked at in these games. One such combinatorial graph game is Grim. Many of the winning strategies of Grim are already known. We note that many of these winning strategies are only available to the first player. Hoping to develop a fairer Grim, we look at Grim played under a slighlty different rule set. We develop winning strategies and known outcomes for this altered Grim. Throughout, we discuss whether our altered Grim is a fairer game then the original.

Autumn Brown Art399 Portfolio, Autumn Brown

Professional Practices (ART 399)

It is easier to approach a difficult topic if it isn’t immediately posed as threatening or sacred. The viewer’s ability to enjoy my pieces, regardless of their prior experience with the subject matter, is my priority. My primary means of creating my work is through drawing, with the end products taking the form of animations and zines. Sequential art provides a unique opportunity to form a relationship with the viewer during the short time they interact with the piece, which many drawings can’t accomplish in the same way. Zines and animations are highly shareable and exist as an experience as …

Animal-Assisted With Nursing Home Residents, Kierstyn Stevens

Scholars Week

This study was conducted to evaluate the use of animal-assisted therapy in nursing home residents, particularly a Nursing and Rehabilitation center in Paducah, KY. Residents of long term care facilities, like a nursing home, face many challenges due to physical and mental changes. Factors contributing to these changes may include financial changes, loss of autonomy, mobility changes, etc. Various articles concerning animal-assisted therapy in elders, residents of hospitals, and residents of long-term care facilities were gathered to examine potential benefits. Findings indicated significant improvement in variables found often in elders, such as anxiety, depression, aggression, and loneliness. Many of these …

Effects Of Using Hemp Hearts As A Feed Additive In Broiler Chicks, Brian Parr, Cheyenne Hooks, Mallorie Snider, Huichang Chae, Tony Brannon

Journal of Agricultural Hemp Research

In this experiment, hemp hearts of differing percentages were fed to broiler chicks for 49 days. The experiment, which was initiated to identify the potential of hemp hearts as a feed source, consisted of four experimental groups and one control group. Each experimental group received a diet containing: 10%, 20%, 30% and 40% hemp hearts; the control group did not contain hemp hearts, but contained soybean meal. As a result, broilers fed a diet containing 20% hemp hearts gained the most weight, t(16) = 2.12, p < 0.05 and feed conversion was also the lowest t(18) = 2.10, p < 0.01. These results indicate the feed efficiency of broilers using 20% hemp hearts was the lowest numerically, but the most efficient qualitatively. The diets consisting of higher percentages of hemp hearts demonstrate a need for additional supplementation.

Relative Size Underlies Alternative Morph Development In A Salamander, Michael P. Moore, Joseph H. K. Pechmann, Howard H. Whiteman

Faculty & Staff Research and Creative Activity

Size thresholds commonly underlie the induction of alternative morphological states. However, the respective importance of absolute and relative size to such thresholds remains uncertain. If absolute size governs expression, morph frequency should differ among environments that influence absolute sizes (e.g. resources, competition), and individuals of the same morph should have similar average sizes across environments. If relative size determines expression, the frequency of each morph may not differ among environments, but morphs within each environment should differ in size relative to one another. We tested these predictions in a salamander (Ambystoma talpoideum) that develops into either a terrestrial …

The Business Of Hemp In North Carolina: Where The Rubber Meets The Road, Obed Quaicoe, Fafanyo Asiseh, Omoanghe S. Isikhuemhen

Journal of Agricultural Hemp Research

Industrial hemp continues to receive a lot of attention in the United States of America with a projected annual revenue growth rate of 18.4 percent by 2022. The momentum industrial hemp has gathered in the past few years has made it the ‘new lucrative crop’ for people to grow. However, many farmers have jumped into hemp farming without first obtaining a realistic economic analysis of hemp farming. In this paper, we seek to review and explore the economic opportunities and challenges of hemp production as a useful guide for reducing risks and maintaining profitability for farmers in North Carolina. Our …

Introversion, Play, And Childhood: The Ideas Behind The Remnants, Sara Talwalkar, Sara R. Talwalkar

Honors College Theses

Closed and confined spaces provide my introverted personality a place to examine, explore, and unwind. Being an introvert has inspired this senior thesis exhibition, exploring the relationship between interior and exterior spaces and child-like play. Growing up I didn’t crave a social life outside of my nuclear family and home. I spent a majority of my time inside my bedroom, but curious about the lively atmosphere outside of my bedroom. The act of play with my siblings would break down my introverted tendencies and present me with new objects, toys, and materials to explore. Now, my dorm room has become …

Roby Joe Dreamboat, Roby Blackwell

B.F.A. Practicum Exhibition (ART 498)

Roby Joe Dream Boat is a perfect play date, Roby Joe Dream Boat is brunch with florals adorning the majority of the table. It is escape. Escapism finding the most beautiful parts of the past and curating a make believe world. Arriving where choices revert back to a surreal childlike viewpoint. Everything is more unapologetic and completely sure of itself. It’s dreaming—it’s dress up!

There is a sense of complication through maximalism that I find interesting. My generation is inspired by the endless influx of media; how Instagram profiles have turned into perfectly planned out color schemes, with set saturations …

Entertainment Media Perceptions Of Minorities In Young Adult Adaptations, Kynnadie Bennett

Honors College Theses

This is an exploration of stereotypical and racist portrayals of minorities, specifically African-American, Latinx, and Native American communities, in film and television in the past and how that has affected representation in film adaptations of young adult literature. Young adult literature is one of the highest-selling genres in literature, purchased by both young adults and actual adults. In recent years, young adult literature has been adapted into film and television series and while representation has improved since the early years of entertainment history, there are still problems in the industry: many of the stereotypes remain, some minorities lack representation, and …
