Effects Of Ultrasound On Amyloid Beta 42 (Aβ42) Mediated Neurodegeneration, Sarah Byrne

Honors Theses

Alzheimer’s disease (AD) is an age related progressive neurodegenerative disease. The exact mechanisms that lead to cell death are not entirely understood. It has been shown that accumulation of amyloid-beta-42 (Aβ42) plaques generated by mis-cleavage of amyloid-precursor-protein is the cause of neurodegeneration seen in AD. This is due to the hydrophobic nature of Aβ42 due to extra two amino acids added to the typical and naturally occurring Aβ40 in the body. These Aβ42 plaques trigger neuronal death because of the toxic nature and stress they exert on the neurons. In this study, Drosophila melanogaster transgenic model where human Aβ42 coding …

Seasonal Changes In Physical, Chemical, And Biotic Factors In Silver Lake, Ohio, Jacob J. Clancy

Honors Theses

The chemical makeup of a body of water can vary greatly depending on what kind of lake it is, the time of year and what kind of runoff enters the water. There are many abiotic factors that make up the water chemistry of a lake such as nutrient availability (Nitrogen and Phosphorous), pH, temperature, oxygen content and conductivity. Each of these factors plays important roles in the successes of many organisms that reside in the lake. The many species of zooplankton and phytoplankton thrive in different water chemistry conditions. Silver Lake is a unique lake in Ohio, because it was …

Effects Of Playing Computerized Versus Tactile Learning Games On Preschoolers’ Attention Skills And Comprehension: A Pilot Study, Samantha Malick

Honors Theses

The ability to attend to relevant information and resist attention to distractors is important for children’s cognitive development. Much has been written in the news about the impact of electronic media on children’s development of attention skills, but little research has been done explicitly comparing children’s attention to relevant information and resistance to distractions across activities that are presented as either a computerized or tactile learning game. The goal of this study is to compare levels of attention and distraction among preschool-aged children while they engage in a common childhood activity, playing a board game that is either presented in …

Challenging The Postwar Narrative: The Art And Agenda Of Boris Lurie, Kiersten Signe Remster

Honors Theses

Art history is shaped, studied, and taught based on narratives, artistic movements, and the biographies of celebrated artists. While contributing to an understanding of prevalent traditions and artists working in those traditions, these narratives are also constructions of inclusion and exclusion that establish art historical placement for certain artists while relegating others to historical obscurity. It is clear what happens to the critical fortunes of artists who are placed within these narratives. Yet what happens to the artists who do not fit within any of the categories established by these constructions? Are they then to be understood as simply minor …

Self Management: Overcoming Barriers To Success, Jazmyn Souryamat

Honors Theses

Individuals with an autism spectrum diagnosis often have a social-skills deficit that may include the tendency to avoid eye contact. In addition, they may have sensory issues and become easily overwhelmed by excessive sensory stimuli. Self-management is a treatment that has been found to enhance the quality of life for individuals with or without an autism spectrum diagnosis. It has been helpful in treating procrastination, used to increase physical activity, lower caloric intake, and increase independence. In this study, self-management treatments were used to increase instances of appropriate social responding and to decrease behaviors that posed a barrier to personal, …

Cross Cultural Study Of Food And Consumer Packaged Good Products In A New Market: Case Study In Thailand, Savanna Everett

Honors Theses

This study examines whether there are differences in consumers’ shopping behavior due to cultural orientation. The study uses comparing samples of American and Thai culture on two occasions. Theory suggests that these two cultural groups have dramatically different shopping practices. Thai, raised in a collectivist society that values price consciousness and sophistication in money handling, differ from Americans raised in an individualist society that traditionally do not have the same values (Ackerman and Tellis 2001).

We argue that differences in culture provide the most likely explanation for the differences in prices between the two types of super markets. The overall …

Devising From A Distance: A Study Of The Difference In Process, Composition, And Audience Response Between In-Person And Digitally-Mediated Choreographic Collaborations, Kathryn Butler

Honors Theses

This paper argues that dance devising shares a value system with that of the digital age, justifying the use of a virtual choreographic site to facilitate geographically distributed collaborations. The presence of technology in our social lives, working environments, and creative practices is steadily increasing. Before we passively let technology digitize and make virtual the choreographic process, or before we expedite this seemingly inevitable trajectory, we need to know what the consequences and opportunities might be. Through use of a controlled empirical investigation, this study analyzed the process experience, composition, and post-performance audience response between in-person and remote choreographic collaborations. …

Correcting Pedestrian Dead Reckoning With Monte Carlo Localization Boxed For Indoor Navigation, Akira T. Murphy

Honors Theses

Localization of phones is a ubiquitous part of the modern mobile electronics landscape. However, there are many situations where the current method of networked localization fails. A Pedestrian Dead Reckoning System where the location of the user is calculated by counting the steps and direction of the user was implemented as an iOS app with python for data analysis. A novel algorithm for wireless sensor localization using Ad-Hoc Bluetooth networks was proposed. A small experiment was performed proving that the system is nearly equal to state of the art algorithms.

Temporal Changes In The Larval Placopecten Magellanicus Population In A Small-Scale Fishery Closure Area In Coastal Maine, Usa, Jessica P. Batchelder

Honors Theses

The Midcoast Maine Collaborative Scallop Project was established in 2013 by fishers, scientists, and policy makers to determine if a small-scale closure area could restore the local Atlantic sea scallop (Placopecten magellanicus) population to an area in coastal Maine that previously supported high scallop densities. These stakeholders established a three by one mile closure area in the Lower Muscle Ridge Channel to assess the response of the adult and larval scallop populations. Understanding the larval dynamics in a closure area is key to evaluating the recovery potential of the population and for future population stock levels. This study …

Dear Reader, How Do We Go On? Letters Of Reflection On Community Care In Climate Activism In Maine, Ester Topolarova

Honors Theses

Climate activist groups in Maine often see their members become too tired to continue organizing. Thus, I decided to explore how these activists enact community care. I conducted my fieldwork with 350 Maine and its local nodes. I explore community care as a practice and as an aspiration. Community care is practiced through the acts of people taking care of each other. Aspiration, therefore, is a way of living and seeing the self as striving to replicate the world activists are fighting for. I conceptualize care as racialized, gendered, classed, and embedded in neoliberal capitalism. In activist meetings, care is …

Examining Interactions Between Opsins And Carotenoid Biosynthetic Proteins In Halophilic Archaea, Alexandru M. Plesa

Honors Theses

Organisms have evolved numerous specialized molecules for constantly responding to environmental changes. Examples of such molecules are the light-driven proton-pump rhodopsins, such as bacteriorhodopsin (BR) and cruxrhodopsin (cR), and the carotenoid pigments, such as retinal and bacterioruberin. In halophilic Archaea, retinal can covalently bind bacterioopsin (BO) and cruxopsin (CO) to form the corresponding protein complexes, and its biosynthesis is indirectly controlled by the activity of the lycopene elongase (Lye) enzyme, which converts lycopene, a retinal precursor, to a form of bacterioruberin. Interestingly, opsins were shown to inhibit the activity of Lye, thereby promoting retinal biosynthesis and indirectly regulating the apoprotein-cofactor …

I Remember It Like This: Essays, Robin C. Lewis

Honors Theses

This thesis is composed of eleven personal essays. As an Environmental Policy senior, I wanted to write down some of my formative stories—not just any stories, but those that may reveal the environmental thread in my life, which, I believe, was somehow instilled in me by my parents. This thread has followed me from Texas to Maine, from childhood to almost twenty-three. It has been supported and tested by various characters along the way, sometimes growing faint, other times stronger. As I prepare for something new, I’ve found it valuable to look back on the people and landscapes and stories …

Trump, Twitter And The Death Of The American Political Party: A Discussion Of The Fate Of The American Party System Before, During, And After The Presidential Election Of 2016, Madeleine Neider

Honors Theses

Abstract: This paper seeks to address the essential question: what happened during the presidential election of 2016 and what does this mean for the American party system? Using qualitative and quantitative analysis, this research suggests that the 2016 election is evidence that domineering policy demanders, such as the Tea Party Movement and Occupy Wall Street, and domineering politicians, such as Donald Trump and Bernie Sanders, used the democratized media to force a top-down realignment of the American party system. A top-down realignment is characterized by the demise of the prominent American political party­– an institution fundamental to our political process. …

Vein Patterning During Juvenile Wing Development In Oncopeltus Fasciatus And Jadera Haematoloma, William R. Simmons

Honors Theses

Wings are a defining characteristic of all pterygote insects and are agreed to originate from a single common winged ancestor. However, essentially nothing is known about the molecular mechanisms that regulate wing development and patterning outside of Endopterygota, and the vast majority of this knowledge comes solely from Drosophila melanogaster. There is reason to suspect that the drastic developmental differences that exist between Endopterygota and Exopterygota have resulted in changes in the mechanisms, timings, or even genes that govern wing development. This study examined the roles of several genes known to be involved in D. melanogaster wing development and patterning …

Crops And Controversy: Industry’S Role In The Gmo Debate, Carina Wallack

Honors Theses

The use of genetically modified crops (also called GM crops, genetically modified organisms, or GMOs for short) has become a highly contested issue. New genetic modification technologies offer a variety of advantages for improving agricultural efficiency. However, some scientists argue that the safety testing conducted thus far does not provide enough information and worry about possible health and ecological risks. Private industry sponsors a great deal of research on genetically modified crops. As the international controversy regarding the use of GMOs has unfolded, the very companies responsible for commercializing genetically modified crops have gained substantial influence in the resulting scientific …

America's National Parks And The Anthropocene: Addressing The Present To Accommodate The Future In Acadia National Park, Sophie A. Swetz

Honors Theses

In 2000, atmospheric chemist, Paul J. Crutzen, and limnologist, Eugene Stoermer, formally proposed the idea of “the Anthropocene,” a new geologic epoch in which humans are the dominant force shaping the Earth. To claim the Anthropocene's existence is to declare that human actions have altered the Earth in such a way that geologic indicators render it a distinct epoch in the stratification of geologic time. This new epoch emerges as a consequence of increased technological development employed to accommodate an anthropocentric human existence. That is, rapid advancements in technology have driven the transformation from a primarily naturally controlled planet to …

Nature And Human Flourishing In The Laws Of Manu And The Daodejing, Qijing Zheng

Honors Theses

By comparing the interpretation of dharma in the ancient Indian Laws of Manu (Manusmṛti) with the concepts of dao in the Chinese classic, Daodejing, this thesis discusses that, despite the plausible perception that the former represents despotic, hierarchical governance while the latter promotes freedom (and even anarchy), the two texts in fact share a similar envision of human flourishing through the following of one's nature, as well as a foundational belief that both laws and political ideals emerge from nature.

When Worlds Collide: Feminism, Conservatism And Twentieth Century Authors, Madison Cooney

Honors Theses

Two streams of literary narratives appearing during the Great Depression grew from personal and historical experiences of their women authors with overlapping but very different perspectives on American cultural history. These were: 1) The accounts of rural frontier Midwestern regional experiences of Laura Ingalls Wilder, as edited and shaped in part by her daughter and writing partner Rose Wilder Lane, in retrospect during the New Deal era; and 2) the 1920s urban African-American experience of Zora Neale Hurston in the context of an emerging national black artistic and intellectual scene. Through a shared feminism emphasizing freedom for women, these authors …

As Good As Niu: Food Sovereignty In Samoa, Emily Gove

Honors Theses

Samoa’s history as an island nation, with its cultural heritage of migratory peoples, followed by settler colonialism and missionaries, has resulted in its uniquely amalgamated food system. Cuisine varies from traditional crops and recipes to imported canned goods, although dependence on the latter has led to wide-ranging health problems. A way to confront these problems is through reclaiming local cuisine, renewing its popularity and promoting the concept of food sovereignty. Through fieldwork based on surveys, interviews, and participant observation in Apia, complemented with a study of activist Robert Oliver’s new cookbooks on Pacific cuisine, this project examines current themes …

The Progression Of Lyme Disease In The State Of Virginia, Margaret Michel

Honors Theses

Lyme disease has spread in the United States from the northeast to more southern and western parts of the country. It has been shown that the tick which most often carries the Lyme disease pathogen (Borrelia burgdorferi) in North America, Ixodes scapularis, has also spread to these new areas of concern. In Virginia, the disease has progressed from the eastern shore to the western, more mountainous regions. Through obtaining historical museum specimens of mice from 11 locations in Virginia, we seek to determine whether the Lyme disease causing pathogen, B. burgdorferi, has always been present in …

Toward A Scientific Investigation Of Convolutional Neural Networks, Anh Tran

Honors Theses

This thesis does not assume the reader is familiar with artificial neural networks. However, to keep the thesis concise, it assumes the reader is familiar with the standard Machine Learning concepts of training set, validation set, and test set [1]. Their usage is intended to help ensure that the Machine Learning system can generalize its training from input examples used during its training to “similar” kinds of examples never used during its training.

The concept of a Convolutional Neural Network (CNN) is one of the most successful computational concepts today for solving image classification problems. However, CNNs are difficult and …

Eating Your Feelings: The Relationship Between Core Affect And Food Choices, Kana V. Rolett

Honors Theses

The psychology of eating behavior is increasingly important given that more than one- third of Americans are obese, with 74% of men considered overweight or obese (Overweight and Obesity Statistics, 2012). This study examines the relationship between core affect and healthy food choices. Though previous research has examined relationships between specific emotions and eating behavior, little is known about core affect or about these relationships in more naturalistic settings (outside the lab). To evaluate the role of core affect in healthy food choices, a field study was conducted in the University of Richmond (UR) dining hall to measure UR students’ …

Development And Evaluation Of Quercetin Nanoparticles And Hot Melt Cast Films For Retinal Neuroprotection, Chau Truong

Honors Theses

The aim of this study was to prepare optimized nanoparticles and hot melt cast films of quercetin and to investigate the release and permeability profile across corneal membranes. The results demonstrate that all formulations can be successfully employed for delivery of quercetin into the eye through the topical route of administration, with films showing significantly better transcorneal permeability.

The Effect Of Font Type On Memory For Instruction, Courtney Upchurch

Honors Theses

The purpose of the present study was to determine whether or not one font type promotes superior memory retention for order over another. Participants were presented with one of three sets of instructions each displayed using a different style of font. They were asked to read the instructions and, following this, were provided with the instructions presented in a different, random order. Their task was to place the instructions back in the order in which they were originally presented. Results indicated that one font style led to better memory for order than the others. In addition, based on participant self-reports, …

Development Of Standard Operating Procedure: Admicellar Polymerization Of Polystyrene Thin Film (Aibn) On Polysciences 30-50Μm Glass Beads Using Cetyltrimethyl-Ammonium Bromide Surfactant, David Langford

Honors Theses

Poly(1-phenylethene), commonly referred to as Polystyrene, is one of the world's most common polymers. Made from the monomer styrene (ethenylbenzene), this polymer is used in a wide range of products from packing peanuts to disposable cutlery. The method of polymerization used in this research project is called admicellar polymerization. This process consists of four main steps: admicelle formation, adsolubilization, polymerization, and removal of admicelle and polymer. Admicellar polymerization has a number of advantages over related methods of thin film polymerization including simplicity and low cost of components and process.

Mississippi Choctaw Women: Preservation And Adaptation From Post-Removal To The 1970s, Elisabeth H. Pepper

Honors Theses

This project analyzes the processes of adaptation and preservation utilized by Choctaw women in Mississippi from the post-Removal period to the end of the 1970s. It focuses specifically on the areas of women's lives concerning work, the domestic sphere, leadership roles, and recreational activities. To inform my research, I used a variety of primary and secondary sources concerning the Mississippi Choctaws, even covering the period before Removal. I studied archival documents, microfilm, newspapers, magazines and pamphlets, as well as secondary resource books concerning this topic. From my research, I concluded that women actively engaged in strategies to preserve their Choctaw …

Everybody's Story: Gertrude Stein's Career As A Nexus Connecting Writers And Painters In Bohemian Paris, Elizabeth F. Milam

Honors Theses

My thesis examines how the combination of Gertrude Stein's career, Paris, and the time period before, during, and after The Great War conflated to create the Lost Generation and affected the work of Sherwood Anderson and Ernest Hemingway. Five different sections focus on: the background of Stein and how her understanding of expression came into existence, Paris and the unique environment it provided for experimentation at the beginning of the twentieth century (and how that compared to the environment found in America), Modernism existing in Paris prior to World War One, the mass culture of militarization in World War One …

Memory Retention Rates Of Gossip-Related Information, Hannah R. Rogers

Honors Theses

The aim of this study is to determine if gossip-related information produces higher memory retention rates than scientific information. Participants completed a two-part survey. During the first part of the survey, participants read nine paragraphs, separated into three categories. Three were scientific, three were non-celebrity gossip, and three were celebrity gossip. After reading each article, participants rated each on a scale of 1-10 based on both personal relevance and how interesting they found each article. After a week delay, participants completed a multiple-choice memory test about the articles read the week before. The study found that while scientific articles were …
