This work presents the usage of the Simultaneous Localization and Mapping library, ORB-SLAM2, in C++ to solve this issue. By using the camera attached to the unmanned aerial vehicle, a map of the area covered by the drone will be created, and landmarks in area will be utilized to navigate throughout the interior of the building without the GPS. Based on previous studies, this navigation method should be viable. Preliminary tests show that this method will …

Encanto The Musical: An Exploration Of Translating Media From Film To Stage, Isabel Perez-Flores

Whittier Scholars Program

I’m going to be honest: I did not go into this project with the intent of radically changing Encanto. I had some points I wanted to expand upon, some improvements and edits that I felt the film could have utilized, but overall, I was satisfied with the way the story was told. The real change, I’ve come to realize, lies not in the story and the script itself, but in the way the story is told. The obvious change is that this version of Encanto, in an ideal world, would be performed in front of a live audience, in a …

The Barriers Preventing Generational Diversity In The Workplace: A Design-Based Research Study On Generational Diversity In The Workplace, Bryan T. Benke

Dissertations

Generational diversity poses numerous challenges within organizations, primarily as workplaces can now encompass up to five generations (BasuMallick, 2020). The scholar-practitioner explored various facets of generational diversity, highlighting barriers that impact the work environment, employee behavior, communication, knowledge transfer, technology adoption, management decisions, employer obligations, and cultural disparities.

Beyond The Finish Line: How Mindset And Setbacks Shape Future Success Of High School Sprinters, Hannah L. Lybbert

Undergraduate Honors Capstone Projects

How does mindset shape sports performance? Using data from high school track and field 100- meter sprint times, I examine how exogenous psychological shocks—caused by running faster or slower than expected due to tailwinds or headwinds—influence subsequent athletic performance. By leveraging instrumental variable analysis and random wind variation, I isolate the purely psychological effects (referred to throughout this paper as “mindset effects”) of performance confidence. I parse out the sustained mindset effects, taking into account athlete-specific fixed effects, and estimate mindset-driven performance effects. In the discussion, I will explore “perceived self-efficacy” (PSE) as a potential mechanism by which these mindset …

The Impact Of Lactoferrin And Iron-Enriched Whey On Iron Absorption, Gastrointestinal Symptoms, And Menstrual Health In Women, Mia Dustin

Undergraduate Honors Capstone Projects

Iron is an essential trace mineral involved in oxygen transport, energy metabolism, and cellular function, yet deficiency remains prevalent among women of reproductive age. In the U.S., approximately 20% of women aged 18-45 years fail to meet daily iron requirements due to lack of iron consumption in the diet, menstrual blood loss, or intense exercise, often leading to anemia, fatigue, and cognitive impairment. While ferrous sulfate is a common form of iron supplementation, it frequently causes gastrointestinal discomfort. Researchers have explored lactoferrin, a glycoprotein with immune and iron-binding properties, as an adjunct to traditional supplementation. This study examines the effects …

Discovering The True Meaning Of Federalist No. 27, Mckenzie Pedersen-Campbell

Undergraduate Honors Capstone Projects

The Federalist Papers are widely known as they helped explain the Constitution and gather support for its ratification. However, what they mean is not always clear. This is problematic, especially when Supreme Court Justices look to the Federalist Papers to help them make decisions. A particularly fascinating example of this problem arose in the case Printz v. United States (1997). Both the majority and dissent argued that their interpretation was supported by Federalist No. 27. That leads to the question of what Federalist No. 27 actually means. By looking at the context surrounding Alexander Hamilton (the author) and previous Supreme …

On The Challenges Posed By Non-Machian Solutions To Relationalism In General Relativity, Zachary Matthew Zito

Undergraduate Honors Capstone Projects

The relationship between Mach’s Principle and solutions to Einstein’s field equations is examined, with special attention to Friedmann-Lematre-Robertson-Walker (FLRW) cosmology. Mach’s Principle is outlined, and the extent to which general relativity fulfills Machs vision is assessed. It is argued that several important solutions to Einsteins equations, particularly the FLRW cosmological models, embody key Machian features. In order to elucidate the FLRW cosmological model, the associated energy-momentum tensor for a perfect fluid under the assumptions of large-scale homogeneity and isotropy is derived and used to obtain the Friedmann equations that govern cosmic expansion. It is shown that FLRW cosmology can be …

Declining Democracy Amid Historical Legacies: Democratization Across The Maghreb, Jacob Sagers

Undergraduate Honors Capstone Projects

Institutions and security forces are vital in determining democratization’s success or failure, but how do they interact with civilians to counteract, or support, existing regimes? Hopes for a fourth wave of democratization were dismantled over the past decade as the Arab uprisings have had inconclusive results, posing a threat to the ideological basis for U.S. foreign policy and Western states' legitimacy. Broad economic and Western foreign policies applied worldwide over the past few decades have also been ineffective at supporting this process and producing sustainable democratic transitions. But what specifically about these factors in the Maghreb gave way to Tunisia’s …

Ethical Concerns And Implications Of Expanded Carrier Screening, Emily Andres

Undergraduate Honors Capstone Projects

The rapid evolution in the field of genetics is often met with uncertainty and skepticism. With the advancements in genetic technologies, expanded carrier screening (ECS) has emerged as a powerful tool in reproductive medicine. Traditionally, carrier screening was provided less broadly, often relying on ethnic-based approaches. However, further advancements have deemed this practice no longer equitable or widely accepted. While ECS provides prospective parents with insight into their genetic risk and may prevent severe genetic conditions, it also raises serious ethical questions for many. These concerns span medical, political, and societal facets including medicalization, defining severity, abortion, legislation, insurability, the …

Tax Increment Financing: A History And Analysis Of Its Success And Failure, Justin Cederlof

All Graduate Reports and Creative Projects, Fall 2023 to Present

Tax increment financing (TIF) is used by cities and towns to subsidize projects within their jurisdictions. The name derives from the growth in the tax base that a (re)development is theoretically responsible for. The increase in tax revenue is directed to funds to pay for the project. TIF is used in 49 U.S. states and each state has unique legislation for its use of it, though there are large similarities between states on how it’s implemented. Research suggests mixed results with whether or not the increase in the tax base is enough to pay off how much money went toward …
