Use Of Edna To Determine The Presence Of Cryptosporidium Spp. In Freshwater Sources In Harlan, Kentucky, Madison Hall

Honors Theses

Cryptosporidium spp. oocysts are transmitted via a fecal-oral route, e.g., water sources, and the parasite is a leading cause of waterborne disease in the United States. Research into Cryptosporidiosis in rural areas is lacking. This study utilized eDNA methods to determine if Cryptosporidium spp. was present in Harlan, Kentucky, an underserved area in Appalachia. We used a pump-powered commercially available Smith-Root Citizen Scientist eDNA (Vancouver, WA) system to filter freshwater sources and collect eDNA. Samples were collected from tap and spring water as controls and three times from five locations on the three tributaries of the Cumberland River: Martins Fork …

City Flags And The Politics Of Urban Revitalization: The Case Of Syracuse, Ny, Grace Risinger

Honors Theses

People tend to care about flags, but are not aware that their city has a flag. A recent wave of flag redesigns has been happening in the United States since a 2015 TED Talk was posted widely criticizing city flags. This subject prompted my professor, Daniel Alvord, to ask for a research assistant for his project to understand this phenomenon. For my thesis, I focus on a specific flag redesign initiative in Syracuse, NY, through an ethnographic case study. By applying previous urban sociological literature to my focus on flag redesigns, I can connect the Syracuse community member’s increased civic …

Selective Melt Recrystallization Of Acetaminophen Polymorphs Through Environmental Control, Eleanor Lowe

Honors Theses

Polymorphism is the ability for a molecule to crystallize into multiple different structures in the solid state. The preparation of one polymorph over another is practically important to pharmaceutical development, as properties of polymorphs can vary and impact the drug delivery method. Polymorph outcomes depend heavily on the environment in which the crystal is nucleated, or initially formed. Acetaminophen, the active ingredient in Tylenol, is one example of a polymorphic compound. Here we use acetaminophen as a model system to better understand primary factors controlling polymorph selection and interconversion. We hypothesize a specific atmospheric environmental factor plays large role in …

Long-Range And Chaotic Active Mixing Of Swimming Microbes In A Vortex Chain Flow, Nghia Le

Honors Theses

We present experiments studying the motion and active mixing of swimming mi- crobes in laminar, vortex-dominated fluid flows. We are testing a theory that predicts the existence of swimming invariant manifolds (SwIMs) - invisible, one-way barriers blocking the paths of self-propelled tracers in the flow in one direction. We also pro- pose that the SwIMs together can form chute structures in three-dimensional phase space that facilitate cross-vortex transport of the microbes. We also observe evidence of how these structures promote long-range transport at different non-dimensional velocities (microbe’s velocity relative to flow velocity). Long-range transport is quan- tified by measuring the …

Instadamn –The Power Of Instagram’S Platform As An Instigator And Indicator For Offline Political Participation Among Young Adults, Natalie Davidson

Honors Theses

Over the past decade, exposure to various forms of political content on social media, as well as social media usage for political means, has been studied by scholars as a link to predicting offline political participation by social media users. While evidence has been gathered that categorizes activity on the platforms of Facebook and Twitter as potential influencers and predictors of offline political behavior, the literature on the political relevance of Instagram as a predictor of offline political participation has yet to be fully explored. Additionally, although younger generations have historically participated in some forms of political behavior (particularly voting) …

Indigenous Storytelling As Decolonial Praxis, Ceremony And At Colby, Georgia Goodman

Honors Theses

This thesis seeks to amplify Indigenous lifeways, diplomacies, sciences, diplomatic relations, and the power of storytelling. This is not a piece analyzing Indigenous culture. Rather, this thesis returns the gaze to the settler colonial state, specifically its storytelling ideologies, to show that systemic practices of inequity in storytelling can be disrupted and decolonized through a recentering of Indigenous ideologies. For example, reciprocity with lands and animals, reflection on positionality and decentering colonial understandings of time and place.

When In Rome, Do As Meloni And Salvini Do: Dissecting The Potentially Extreme Nature Of The Political Communication Of Italy's New Right-Wing Populist Duo, Thomas S. Erie

Honors Theses

The fundamental question that this research project aims to answer is: what are the defining characteristics of the style and rhetoric of the communication practices of Italian right-wing populist leadership and how do they relate to those of fascism? After the Italian elections of 2022, in which a right-wing populist coalition led by Giorgia Meloni and Matteo Salvini came to power, further research is necessary to understand the potential implications of this electoral result. Political communication has developed in recent years to shift towards direct communication from the leader to their base through social media and speeches published on YouTube. …

Stereotype Threat In Older Adults’ Episodic Memory Tests: Susceptibility And Protection, Talia Barrett

Honors Theses

The objective of the present study was to investigate whether prior task success would protect older adults against stereotype threat in an episodic memory test. Previous experiments have established that, whereas stereotype threat negatively impacts older participants’ episodic memory performance, prior task success benefits it. However, up until this point, researchers had yet to combine the two manipulations to test their joint effect on episodic memory. Participants were randomly assigned to read a stereotype threat or neutral passage, after which they were placed in the success or no success group. Participants next received a stereotype condition reminder, and they then …

Does Tssh Deletion In Paraburkholderia Bonniea Affect Its Symbiosis With Dictyostellum Discoideum?, Anna Chen

Honors Theses

Paraburkholderia are amoeba resistant, gram negative bacteria that form facultative symbiotic relationships with D. discoideum, a soil dwelling amoeba host. Three species of Paraburkholderia, P. agricolaris, P. hayleyella, and P. bonniea are able to persistently infect nonnative, or symbiont free, D. discoideum. These three species share a type III secretion system (T3SS) and type VI secretion system (T6SS) that is absent in other close relatives We hypothesized that the ability to persistently infect D. discoideum may be partially attributed to the T3SS and T6SS shared across the three species of Paraburkholderia.

The goal was to test the phenotypic effect of …

Changes In Ecosystem Processes And Functional Traits Over An Elevational Gradient, Tiana Issa

Honors Theses

Elevation gradients have been used to understand how climate change impacts various ecosystems processes by substituting distance across elevation with time, reflecting a previous, colder climate. To monitor the changes in soil organic carbon (SOC), plant community, and functional traits across time in the face of climate change, this study used space-for-time substitution to emulate a long-term study with elevational gradients and revisited the same gradient for nearly two decades to monitor elevational effects across time. With this research, I aim to answer the following questions: (1) How does elevation impact ecosystem processes and alpine plant traits? (2) How does …

Who’S Laughing Now? Satire’S Effect On Negative Partisanship, Emma West

Honors Theses

“Negative partisanship,” most basically defined as the phenomenon whereby Americans largely align against one party instead of affiliating with the other, has grave implications for democracy: it has already affected productivity in Congress, the acceptance (rather, lack thereof) of election results (e.g. 2016), and watered down the importance of ideology in American politics. Parsing the independent variables that influence negative partisanship is vital in combating its detrimental effects, and this project proposes satire as a possibility. An analytical history of both topics is explored. Interestingly, psychological mechanisms for interpreting satire and the out-party share many similarities in mechanisms of subjective …

Petroleum And The Politics Of Decolonization In Indonesia: A Study Of Economic Development And Nationalism, Jan P. Wenger

Honors Theses

This study examines Indonesia’s reliance and independence on foreign direct investment (FDI) and multinational corporations (MNCs) in the oil and gas sector. Analyzing historical, economic, and political primary and secondary sources and conducting qualitative interviews, the research explores the friction between economic development aspirations and nationalist sentiments. The study reveals that the current ambiguity surrounding FDI and MNC policies in Indonesia’s oil and gas sector can be traced back to the country’s economic decolonization and demonstrates that Indonesia’s economic policies towards these factors shifted in the aftermath of political change. Since gaining independence, Indonesia has strived to balance the pursuit …

On The Pursuit Of Developer Happiness: Webcam-Based Eye Tracking And Affect Recognition In The Ide, Tamsin Rogers

Honors Theses

Recent research highlights the viability of webcam-based eye tracking as a low-cost alternative to dedicated remote eye trackers. Simultaneously, research shows the importance of understanding emotions of software developers, where it was found that emotions have significant effects on productivity, code quality, and team dynamics. In this paper, we present our work towards an integrated eye-tracking and affect recognition tool for use during software development. This combined approach could enhance our understanding of software development by combining information about the code developers are looking at, along with the emotions they experience. The presented tool utilizes an unmodified webcam to capture …

Pluralistic Ethical Personalism, Qifan Hu

Honors Theses

In the thesis, I sketch out a general outline for a pluralistic, personalist theory of ethics. This theory intends to capture the phenomenon that our life experience is saturated with ethical and other kinds of values; and it also emphasizes the idea that each ethical agent, or human being, has a unique ethical project that is understandable in light of various ethical values.

The Lie-Brary Of Congress: Misinformation’S Grip On The American Legislative Process, Caleb Bitting

Honors Theses

This thesis investigates the influence of misinformation on the policy-making pro- cess by examining its temporal relationship with congressional speech on the floor of Congress. Through the application of Granger causality tests, I aim to determine the extent to which misinformation permeates political discourse and affects representatives from both political parties. My findings reveal that misinformation drives congressional speech on certain issues, and it appears to have an asymmetrical impact on Republicans and Democrats. While not set up to answer the question about a false dichotomy, my thesis hints that Republicans spread significantly more systems-based misinformation than their Democratic counterparts.

The Effect Of Blue Mussel (Mytilus Edulis) Extinction On Ecosystem Function In The Gulf Of Maine Rocky Intertidal, Sophia K. Montague

Honors Theses

Stressors associated with climate change including thermal stress and ocean acidification inhibit the growth and reproduction of many species, including the ecologically and economically important blue mussel species in the Gulf of Maine (GOM). Established scaling relationships between mussel size, abundance, and water filtration suggests that the decline of mussels will stunt GOM water filtration. This change in the rate of water filtration could have large effects on the abundance of phytoplankton, abundance of invertebrate larvae, abundance of nutrients and organic material, food web stability, and biodiversity. Overall, this thesis explores the effect of blue mussel (Mytilus edulis) …

Finding The Common Denominator: Understanding The Shared Experiences Of Female Math Majors, Abigail R. Rosenbaum

Honors Theses

Despite efforts to increase gender diversity in STEM fields, women remain underrepresented in mathematics, especially in advanced academic and research positions. This study aimed to explore the experiences of female math majors as they attempt to navigate this male-dominated space. Through qualitative interviews with seven female math majors, two female math professors, and a focus group with education majors at Woodbridge College, small liberal arts college in the United States, several common themes were identified that define the experiences of female math majors. The findings suggest that math is held at an elevated status in society and that there is …

From Schleswig To Anschluss: The Plebiscites And Referendums Of Interwar Germany, Matthew J. Rocha

Honors Theses

This paper aims to bridge the gap between the plebiscites following the First World War and the referendums of the Third Reich. To this point, the literatures on these sets of votes have remained completely separate. No scholars have considered the NSDAP’s votes in the context of the postwar votes. By comparing and contrasting these groups of plebiscites for the first time, this paper will shed light on the democratic backsliding of interwar Germany.

This paper argues that when planning their referendums, the leaders of the Third Reich had the immediate postwar plebiscites in mind and were, in some cases, …

Geology, Uranium, And Apartheid: South Africa’S Nuclear Program And The International Politics Of The Cold War, Andy Rightmire

Honors Theses

This paper examines the history of mining and uranium and its importance in South Africa’s nuclear history. It begins with the development of minable mineral deposits in South Africa through geologic processes and ends with the South African signing of the Non-Proliferation Treaty (NPT). The paper explores the intermittent period between creating the Atomic Energy Board and developing South Africa’s energy program through assistance from the United States and France. As the apartheid government brought sanctions to South Africa, the government began considering nuclear weapons through a different lens to project power. South Africa slid towards isolation under sanctions from …

Elliptic Curves Over Finite Fields, Christopher S. Calger

Honors Theses

The goal of this thesis is to give an expository report on elliptic curves over finite fields. We begin by giving an overview of the necessary background in algebraic geometry to understand the definition of an elliptic curve. We then explore the general theory of elliptic curves over arbitrary fields, such as the group structure, isogenies, and the endomorphism ring. We then study elliptic curves over finite fields. We focus on the number of F_q-rational solutions, Tate modules, supersingular curves, and applications to elliptic curves over Q. In particular, we approach the topic largely through the use …

Portraits Of Practice: A Case Study On Elementary Schools Successfully Implementing Multi-Tiered Systems Of Support, Catherine "Cat" Merkle

Honors Theses

Multi-tiered systems of support (MTSS) is an educational framework that aims to make the general education classroom more inclusive to all students and types of learners. MTSS has been found to improve student growth and achievement and decrease special education referrals through the use of layered supports that allow students to stay in the classroom as much as possible. There is a direct focus on progress monitoring, universal screening, and data-based decision making in order to ensure that all students are getting the support they need, whether it be universal, group-based, or individualized. This study aimed to understand what factors …

Tracing North Atlantic Continental Erosion Events During The Mid-Pleistocene Transition, Cecilia T. Bowe

Honors Theses

The Mid-Pleistocene Transition (MPT), which occurred between 1.2 and 0.7 Mya, is characterized by changes in the periodicity and intensity of glacial-interglacial cycles. Early research into this event found that it was not triggered by changes in orbital forcing, but rather by internal climate processes. Previous studies have constrained a probable two-step mechanism, in which erosion of regolith under ice sheets increased glacial volumes and contributed to increased carbon sequestration in the Southern Ocean. Additional research has built on this, suggesting that increased glacial erosion of cratons surrounding the North Atlantic preceded a major weakening of the Atlantic Meridional Overturning …

Testing Evolutionary Conservation Of Sex Determination In Lepidoptera Using Crispr/Cas9 Gene Editing, Sophia Schroeder

Honors Theses

The mechanism of sex determination in Lepidoptera is largely unexplored, and limited to knowledge of only a few genes. Adult Lepidoptera have obvious sexually dimorphic qualities, such as their genitalia. However, significant sex determination genes are not imperative for the adult developmental stage. Knockouts of some sex determination genes (doublesex isoforms) are shown to be lethal in the embryonic and larval stages of development in several animals. However, it is unclear whether this is due to their respective impact on sex determination and sexual dimorphism, or the existence of another function, such as pleiotropy, within a particular gene. Moreover, …

Merchants Of Blood And Gunpowder: The English Arms Trade In West Africa, Jaime K. Schneider

Honors Theses

The period between 1500 and 1650 saw the development of a transoceanic trade network, multiple European colonial empires in the Americas, and rapid developments in firearms technology. Combined, these factors laid the groundwork for two interrelated phenomena, the transatlantic slave trade, and the emergence of a global trade in arms. Examining the documents of the Royal African Company and assembling a broad selection of secondary sources, this paper seeks to contribute to the ongoing debate over the role of slavery in the development of modern capitalism. This paper argues that the transatlantic slave trade was vital for the development of …

Food As A Vector For Change: Lessons From The Third Sector On Improving Livelihoods With Nutritional Knowledge In Medellín And Bogotá, Solomon Treister

Honors Theses

In this thesis I argue that improving diet in communities depends on building nutritional knowledge. In examining the role of community level organizations, I look specifically at how knowledge is conveyed through agriculture and gastronomy. This project analyzes how civil society organizations work to reintegrate individuals into food systems, compelling consumers to take agency over their diets and pursue better livelihoods. The industrialization of food systems has fundamentally changed the way humans connect with food and diet. In Colombia, internal displacements and urban migration have accelerated a loss of connection with the land and food processes. At the same time, …

Examining The Impact Of Living Arrangements On Children's Academic Achievement, Rachel G. Coan

Honors Theses

In my paper I examine how different living arrangements impact how well a child performs in school. The living arrangements are: living with both biological parents, living with biological mother, and living with biological father. Using a linear regression method, I regress living arrangements against GPA and find that children who do not live with both of their biological parents are expected to perform about 0.3 GPA points worse in school than children who do. With added control variables the difference in predicted GPAs decreases. Additionally, I find that living arrangements aren’t predicted to impact children differently depending on their …

Map, Census, Museum: Imagining The Malaysian Nation-State And The Malay Identity, Jackson Rockett

Honors Theses

Using historian Benedict Anderson's framework from his seminal text Imagined Communities of examining nation-building and identity construction through colonial artifacts, this thesis turns to maps, censuses, and museums to better understand the colonial and post-colonial imagining of the country that is now known as Malaysia. Reconciling with regional histories that predate the nation-state and defy the contemporary boundaries of territoriality, this thesis largely seeks to elucidate the contestation between colonially-imposed ideas of spatiality, categorization, and the reproduction of history with the modern Malaysian nation-state and the conflation of ethnicity with nationalism from which much of this contestation is derived from.

Thanks, It's Second-Hand: Shifting Values Of Second-Hand Clothing In Mexico City, Sofia Arleo

Honors Theses

This thesis is an analysis of the relationship between people and clothing in Mexico City. Using ethnographic snapshots, local histories and scholarly research on used clothing, this thesis looks at how the economic and emotional value attached to second-hand clothing is determined by place, story and social identity. This thesis questions how clothing changes value as it travels between the United States, open air markets that have existed since the Aztec empire and curated second-hand and vintage stores in Roma Norte, one the city’s most affluent neighborhoods. Second-hand clothing is unique in that it has an added narrative from its …

Jewish Presence In The Venetian Empire: A Challenge To Venetian Mythology, Avery Rosensweig

Honors Theses

This paper attempts to explain the significance of Jewish presence in the Venetian Empire in the context of the myth of Venice. Jews were officially permitted to settle in Venice in 1516, but their connection with the Venetian Empire goes further back. Jews were important for the success of the Venetian Empire, particularly from the sixteenth century onward. The permanent settlement of the Jews in Venice directly impacted the very ideology of the Venetian Empire.

Although the phrase "myth of Venice" was developed by twentieth-century historians, Venetians perpetuated the myth and wove its ideals into the foundation of the Venetian …

Food And Fuel: Investigating Expert Perspectives On The Intersection Of Solar Development And Farmland In Maine, Ellie Hankin

Honors Theses

Maine has established lofty goals including a 100% renewable portfolio by 2050 and increasing local food production by 30% by 2030 (Final, 2020; Maine, 2020). The National Renewable Energy Laboratory conducted a study on state technical potential for solar installation and included 4% of Maine farmland, equivalent to 52,000 acres being taken out of the food system for energy generation (State, 2021). Increased pressure on farmers and demand for solar installations has created a land-use conflict. This study investigates expert perspectives on the intersection of solar development and farmland in Maine. A total of 17 interviews with farmers, policy advocates, …
