Echolocation On Manifolds, Kerong Wang

Honors Theses

We consider the question asked by Wyman and Xi [WX23]: ``Can you hear your location on a manifold?” In other words, can you locate a unique point x on a manifold, up to symmetry, if you know the Laplacian eigenvalues and eigenfunctions of the manifold? In [WX23], Wyman and Xi showed that echolocation holds on one- and two-dimensional rectangles with Dirichlet boundary conditions using the pointwise Weyl counting function. They also showed echolocation holds on ellipsoids using Gaussian curvature.

In this thesis, we provide full details for Wyman and Xi's proof for one- and two-dimensional rectangles and we show that …

It explores the cultural, social, economic, and moral dimensions circumscribing societal attitudes and regulatory policies toward alcohol over time. The thesis examines how alcohol served as a tool of conquest and oppression during the colonial era, facilitating the subjugation of Native populations and fueling the transatlantic slave trade. It delves into the complex dynamics of alcohol consumption and regulation in the early republic, highlighting the …

Psychological Well-Being And Music Among Children, Elle Chrampanis

Honors Theses

The purpose of this instrumental case study was to explore how music supports kindergarteners’ well-being in an elementary music classroom through the lens of PERMA, a framework for well-being developed by Martin Seligman. PERMA stands for positive emotions, engagement, relationships, meaning, and accomplishment. An additional goal was to see how applicable this framework was to kindergarteners. Accordingly, a five-week music program was developed and taught at a local elementary school. A typical elementary music curriculum was developed consisting of lessons that included a welcome song, a rhythm activity, a musical storybook, the sequential learning of a song, and a goodbye …

Campus Sexual Assault: Title Ix Regulations, Mandatory Reporting, And Minimization, Meghan E. Quinn

Honors Theses

Campus sexual assault (CSA) is an ongoing and rising crisis that affects many young adults in the United States. Although CSA rates have continued to rise, it is still an institutionally under-examined issue. One major factor that has aimed to reduce CSA within the campus environment is the increase in Title IX and mandatory reporting (MR) policies and regulations. Thanks to laws, like Title IX, the general population has become more educated and aware of sexual assault – even in the face of increased prevalence rates. Therefore, CSA research is necessary in order to get to the root of this …

The study aimed to determine (1) the cut-off points of the drum sampler to better understand its performance characteristics and (2) to investigate indoor air quality, specifically within makerspaces on Bucknell University’s campus. The research highlighted the novelty of applying LA-ICPMS for time-resolved aerosol composition analysis, demonstrating the potential for low-cost pollution concentration studies. The characterization experiments did not yield expected results, but the …

Experimental Evaluation Of Mesh Size In Physically Crosslinked Polymer Gels Using Dynamic Light Scattering, Duncan M. Hill

Honors Theses

Block copolymer gels are under consideration as drug delivery patches. Controlling and modeling the transport inside the gel is an important contribution to the successful delivery of pharmaceuticals. The diffusive transport of a solute – such as a therapeutic compound – within the gel can be described by the mesh size of the gel, which is defined as the distance between polymer chains. Existing experimental evaluations of mesh size do not work for block copolymer gels due to differences in the fundamental gel structure. As such, an experimental method of measuring mesh size of block copolymer gels using dynamic light …

The Precedence-Constrained Quadratic Knapsack Problem, Changkun Guan

Honors Theses

This thesis investigates the previously unstudied Precedence-Constrained Quadratic Knapsack Problem (PC-QKP), an NP-hard nonlinear combinatorial optimization problem. The PC-QKP is a variation of the traditional Knapsack Problem (KP) that introduces several additional complexities. By developing custom exact and approximate solution methods, and testing these on a wide range of carefully structured PC-QKP problem instances, we seek to identify and understand patterns that make some cases easier or harder to solve than others. The findings aim to help develop better strategies for solving this and similar problems in the future.

Associations Between Loneliness And Social Anxiety: Predictors Of Life-Satisfaction In Young Adults, Desiree Groce

Honors Theses

This research builds upon current findings pertaining to life-satisfaction. Loneliness, related to inadequate well-being, has been shown to negatively affect various domains of one's life. Moreover, Social Anxiety Disorder (SAD) has negative consequences that have been shown to affect the quality of one's well-being. The present research conducted two studies to elucidate the connection between loneliness and SAD as potential predictors of life-satisfaction. The first study sought to clarify the relationship between social and emotional loneliness and life-satisfaction. It was predicted that lower social loneliness scores will predict higher life-satisfaction scores, and lower emotional loneliness scores will predict higher life-satisfaction …

A Comparison Of Symptom Profiles In Probands With 16p11.2 Deletion And Duplication Syndromes: Repetitive Behavior And Psychosis Proneness, Adrianna Rakauskas

Honors Theses

The present study examines two classes of behavior in probands with the 16p11.2 duplication and deletion: repetitive behavior and psychosis spectrum behavior. It was hypothesized that 1.) deletion and duplication cases will differ significantly in the means and profiles of repetitive behaviors across five subscales and 2.)16p11.2 duplication cases will exhibit more schizotypal traits than the deletion cases. Data on 94 total participants was obtained from the Simmons Variation Individuals Project. Three scales were used to measure behavior: the Childhood Routines Inventory-Revised, the Childhood Oxford-Liverpool Inventory of Feelings and Experiences, and the Child Behavior Checklist. Data analysis was conducted using …

Curriculum, Knowledge, And Power: A Critical Race Approach To Content Analysis Of Social Studies Textbooks, Eliza G. Ray

Honors Theses

This study uses Critical Race Theory (CRT) as a theoretical framework to examine the portrayal of the U.S. Revolutionary War in three 5th grade social studies textbooks approved by the state of Florida’s curriculum standards. Textbooks have been a focal point for political debate, most recently influenced more by politicians than by educators. A qualitative rubric was developed to evaluate the textbooks, examining the extent to which they include a CRT telling of the Revolutionary War. This rubric was informed by the tenets of CRT in educational research as described by Solorzano and Yosso (2002). Consistent themes arose from the …

Evaluating Field Evidence Of Fine-Grained Sediment Abrasion In Gravel-Bedded Rivers: A Case Study Of The Lillooet And Suiattle Rivers In The Cascade Volcanic Arc (British Columbia, Canada, And Washington, Usa), Devin T. Johnson

Honors Theses

Steep, gravel-bedded rivers are important sites for studying gravel abrasion, where material transported as bed load experiences size reduction and rounding due to grain-to-grain collisions. Studying fine sediment (diameter) abrasion and grain shape changes in fluvial systems is more challenging due to difficulties in quantifying sediment shape at this scale, but it is assumed that fine particles traveling in suspension do not experience abrasion. Improvements in particle characterization technology now allow for the accurate, rapid quantification of particle shape for sediments as fine as 0.8 μm through dynamic image analysis. Here we use the Camsizer X2 (CX2) to test the …

Computationally Modeling The Human-Structure Interaction Response Of An Occupied Cantilevered Structure, Brennan Smith

Honors Theses

There is a limited understanding of the impact that passive human occupants have on a dynamic structural system, referred to as Human-Structure Interaction (HSI). Cantilevers are naturally prone to excessive vibrations due to their long unsupported spans, and cantilevered structures such as those commonly found in the seating area of a stadium facility or concert hall are designed to support a high density of occupancy.

This study determined that HSI in cantilevered structures can be modeled using a simple two-degree-of-freedom system. The results of the model were validated by data that was collected on a small-scale laboratory structure intentionally designed …

Understanding Para-Athlete Inclusion In Post-Secondary Athletics, Rayven J. Sample

Honors Theses

This qualitative study utilized thematic analysis of six interviews with elite Para-athletes who were currently enrolled at a four-year undergraduate institution and were actively competing or training in any Para-sport to understand inclusion of Para-athletes within the NCAA. This investigatory research sought to identify barriers present in the NCAA’s structure and advocate for positive change as more Para-athletes desire to access collegiate athletic resources due to increasingly higher standards of performance within Para-sport. Para-athletes discussed five key themes during interviews; “Disability Mindset” or the way athletes conceptualized their presence within the athletic environment; sources of education available to athletics staff …

Examining The Relationship Between Subclinical Borderline Personality Disorder And Social Support Networks, Gabriella D'Alicandro

Honors Theses

The purpose of my study was to investigate the relationship between subclinical Borderline Personality Disorder and social support in situational measures such as social provisions, network size, and network satisfaction as well as dispositional measures such as support seeking and socially supportive behaviors. I hypothesized that BPD scores would be negatively correlated with all dispositional support measures. I also predicted that in situational support measures, BPD would have a negative correlation. I hypothesized when confronted with romantic stressors participants would receive more support when confounded with the workplace stressors. Participants (N= 178; 146 women 28 men, 3 nonbinary individuals, and …

Exploring The Nexus Gender Equality And Economic Development In China: A Comparative Analysis, Hejie Liu

Honors Theses

This study will document the extent to which China continues to be affected by the influence of traditional gender norms, and the degree to which gender relations in China are changing in terms of culture, behavioral norms, labor force participation, and family structure. The study will also document the Chinese government’s family planning policy and marriage law that reflect traditional gender norms. In establishing the current state of gender equality in China, this study will assess the current and potential future impact of gender norms on economic growth and population growth. Subsequently, the Chinese experience will be contrasted with Japan …

Mind, Body, And Farmland: The Agricultural Revolution Of Regenerative Agriculture And The Social Construction Of Sustainability., Amanda C. Pennett

Honors Theses

An agricultural revolution has begun to take place in light of the growing awareness of environmental issues that impact crop production on farms. In the beginning of the fall of 2022, I began to study the culture of regenerative agriculture in rural Pennsylvania using anthropological methods, including participant-observation and semi-structured interviews, working alongside local farmers. I was also interested in uncovering the flaws in our current industrial agricultural system and how farming could be reimagined to benefit farmers’ mental health, soils, and ecosystems while privileging the voices of those farmers committed to regenerative farming. The ongoing evolution of regenerative farming …

The Populist Wave: Unpacking The Global Drivers Of 21st Century Right-Wing Populist Support, Ellie Fallon

Honors Theses

This thesis investigates the underlying causes of the global rise in right-wing populism support in the twenty-first century. I will examine both the origins of these shifts in public opinion and their consequences for political systems and global interactions. My analyses will take two forms: (1) a cross-national analysis of the rise in right-wing populism in 34 of the 38 member states of the Organization for Economic Cooperation and Development (OECD) to explore the demographic factors that exhibit a relationship with populist attitudes and (2) case studies of right-wing populism in the contemporary United States (with particular attention to former …

Politicizing The Past: The Exploration Of Revolutionary Collectivity Within Neoliberalism In Dionne Brand’S In Another Place, Not Here And Rita Indiana’S Tentacle, Siobhan Nerz

Honors Theses

This thesis explores the depictions of revolutions in the two Caribbean novels In Another Place, Not Here by Dionne Brand and Tentacle by Rita Indiana. I analyze how the novels explore the potential for political collectivity within neoliberalism through their depictions of the environment and same-sex relationships. I also examine how both authors engage their reader by forcing them to confront their positionality within the economic system. While Brand imagines ephemeral moments of collectivity within neoliberalism, Indiana shows revolutionary individual and collective action is inhibited by late-stage capitalism. Paring these novels together shows how contemporary individuals of differing positionalities can …

Defending The Role Of A Principle Of Proportionality In Just Punishment, Emma Mecklenburg

Honors Theses

What makes a punishment just or unjust is a familiar topic that the public and scholars alike recognize as an important question. Many factors are involved in conversations surrounding the just length of sentences, but this paper will specifically investigate two central questions: First, what makes a punishment just, and second, what role does a principle of proportionality play in thinking about just punishment.

The Value Of Prison Education: Evaluating The Impact Of Education Through Desistance, Cheryl Chan

Honors Theses

The United States faces an epidemic of incarceration, draining resources, disrupting families, and hindering societal participation. Prison education emerges as a method to address this cycle, with vocational and academic programs being pivotal. While vocational programs are more common, their long-term efficacy remains uncertain. Academic education, exemplified by programs like the Bard Prison Initiative, provides incarcerated individuals with an opportunity to change. Typically, the success of these programs are measured using recidivism. However, recidivism has become too narrow of a measure to properly capture the nuances of an education. There has been an emerging body of scholarship studying desistance and …

An Investigation Of The Correlation Between Polymer Solution Entanglement And Electrospun Polycaprolactone Fiber Mechanics, Manasa Sujatha Rajeev

Honors Theses

The aim of this study was to determine the role of entanglement in the mechanical properties of electrospun polycaprolactone (PCL) fibers. PCL is a useful polyester due to its favorable properties such as its biocompatibility and biodegradability. Multiple concentrations of PCL were dissolved in a 3:1 acetic to formic acid solvent. Fibers were formed using an electrospinning technique. Entanglement is a required parameter to produce fibers, thus the number of entanglements per polymer (ne) was calculated, as well as the corresponding concentrations. Smooth continuous fibers were found to form between 13 w/v% and 17 w/v%. Mechanical analysis, such as three-point …

Trading Perspectives: The Impact Of Gender In Shaping National Trade Policies, Katherine Kwiatkowski

Honors Theses

Economic and political factors have been shown to influence the trade policy decisions of national leaders. The impact of a national leader’s gender on their trade policy preferences remains an underexplored area of research. The increasing share of female national leaders raises the question of whether their policy preferences vary from those of male leaders because of their gender. In this study, I utilize the gender of a nation’s leader to implement a two-way fixed effects regression that analyzes the impact of gender on a leader’s trade policy preferences. Controlling for factors that could also impact a leader’s trade policy …

Functionalized Gold Nanoparticles And Halogen Bond Interactions With Neonicotinoid Pesticides, Molly Mccuen “Mackey” Sherard

Honors Theses

Neonicotinoid (NN) pesticides have emerged globally as one of the most widely used agricultural tools for protecting crops from pest damage and boosting food production. Unfortunately, some NN compounds, such as extensively employed imidacloprid-based pesticides, have also been identified as likely endangering critical pollinating insects like honey bees. To this end, NN pesticides pose a potential threat to world food supplies. As more countries restrict or prohibit the use of NN pesticides, tools are needed to effectively and quickly identify the presence of NN compounds like imidacloprid on site (e.g., in storage areas on farms or pesticide distribution warehouses). This …

The Effect Of Solvent Identity And Hydride-Donor On The Reduction Of Co2 Into Useful Fuels, Abigail Mcentire

Honors Theses

One possible strategy for decreasing CO2 emissions is through electrocatalytic reduction reactions to convert the CO2 back into combustible fuels , such as methane or methanol. However, it can be challenging to control the reaction to select one of these useful fuels as opposed to carbon monoxide or formate. Our strategy is to investigate a specific hydride donor and solvent combinations for which the reaction favors conversion to methanol. It was found that in acetonitrile , several hydride donors were capable of selective reduction of CO2 to the methanol oxidation state.

Black And Blue All Over: Whose Lives Matter?, Bella Purvis

Honors Theses

This study investigated the influence of beliefs about race on support for the Black Lives Matter (BLM) and Blue Lives Matter (BluLM) movements, mediated by attitudes towards police and beliefs about white privilege. Utilizing a sample of undergraduate university students, data were obtained through a survey measuring beliefs in the biological and social constructs of race, support for police, belief in white privilege, and attitudes toward BLM and BluLM. Results indicated that individuals who perceive race as a biological construct are less likely to support BLM and more likely to support BluLM, while beliefs in white privilege and attitudes towards …

The Effect Of The Expanded Child And Dependent Care Tax Credit On Maternal Labor Supply, Abby Letocha

Honors Theses

Policies that subsidize childcare have many potential economic benefits such as mitigating the high cost of childcare, incentivizing families to have more children, increasing paid childcare participation, and increasing parental labor supply. In this paper, I focus on the effect of childcare subsidies on maternal labor supply through a tax policy expansion. The Child and Dependent Care Tax Credit (CDCTC) is the primary federal childcare subsidy in the United States, and it was temporarily expanded in 2021 under the American Rescue Plan Act. This expansion increased the generosity of the credit and made it fully refundable for the 2021 tax …

The Effects Of Parasitoid Wasps On The Intra- And Interspecific Competition Of Zaprionus Indianus, Camille R. Walsh-Antzak

Honors Theses

Understanding the mechanisms underlying the success of biological invasions is essential to employ effective prediction and management strategies. The release of natural enemies in invaded regions (enemy release hypothesis) and increased competitive ability are major hallmarks of invasive species, however, these two processes are rarely studied within the same context. Here, we examined the role of ERH in influencing the competitive outcomes of an invasive insect pest, the African fig fly (Zaprionus indianus). In Virginia orchards, Z. indianus repeatedly outcompetes co-occurring drosophilid species. However, the mechanisms underlying the success of Z. indianus are poorly understood. Parasitoid wasps specializing in Camill …

Divided Discourse: Analyzing Abortion Rhetoric In The 2016 Presidential Debates, Ella Hayes

Honors Theses

How did the party affiliation of the speaker affect the rhetoric used to talk about abortion in the 2016 American presidential election? Using computer-assisted qualitative analysis and coding for instances of framing, metaphors, and bridging rhetoric, I look at debate transcripts during the election cycle from the American Presidency Project, tracing both Democratic and Republican primaries into the general election. I argue that across all debates and speeches, Democrats invoke the“morality as empathy metaphor and the Nurturant Parent model in their arguments more than Republicans. In contrast, I argue that Republicans invoke the“morality as strength" metaphor and the Strict Father …

Longitudinal Associations Between Peer Victimization And School Belonging In Elementary-Aged Children, Bridget E. Mcguiness

Honors Theses

Belonging is crucial for children’s social adjustment, and peer victimization has the potential to threaten belonging. Alternatively, it is possible that low levels of belonging can elicit higher victimization. My study determined the directionality of the relationship between peer victimization and belonging and whether gender moderated the relationship. There was no evidence that peer victimization was associated with decreases in classroom belonging, but low belonging was associated with higher levels of peer victimization. Gender did not moderate the relationship.
