Gabelli School of Business Honors Thesis Collection

The goal of this research is to critique current bias detection and reduction methods in predictive healthcare artificial intelligence algorithms by looking at whether the accuracy of algorithms designed to predict breast cancer survival can be increased by including sensitive attributes – such as race, origin, socioeconomic status, marital status, and income – that are typically removed or altered by these bias detection and reduction methods. The research questions guiding this study are: Can including biases that represent disparities in the overall population in training datasets produce more accurate predictions in predictive breast cancer algorithms? How can we use these …

Making Financial Sense Of The Movies: How Streaming And Covid-19 Have Distorted The Theatrical Window, Sebastian Martinez-Canedo

Gabelli School of Business Honors Thesis Collection

The research assesses the viability of the multibillion-dollar theatrical exhibition business by examining two key parts: the theatrical window and the theatrical run. First, the research explores how each one has changed over time, particularly in light of streaming and the COVID-19 pandemic. Second, it looks at the statistical relationship between the two. The findings are that the theatrical exhibition business is unviable due to the shortening of the theatrical window. Furthermore, a weak correlation between the run and window signals a fraught relationship between studios and theaters which negatively impacts the financial viability of both. As such, the future …

Fda Overreach: Is Your Pet’S Health A “Major Question” To You?, Ross C. Reggio

Washington and Lee Law Review

Pharmacy compounding of drugs for companion animals and humans is as old as time. For hundreds of years, pharmacists created these drugs using active pharmaceutical ingredients, otherwise known as bulk drug substances, to address the medical needs of these patients. Congress recognized this longstanding practice when it enacted the Food, Drug, and Cosmetic Act (“FDCA”), with lawmakers then noting that while pharmacists, physicians, and veterinarians were already highly regulated by the states, mass-producing drug manufacturers were not regulated. The FDCA would regulate such manufacturers.

Thereafter, pharmacy compounding from bulk drug substances continued for decades after the FDCA’s enactment and without …

Renewable Energy And Defense Power In Japan, Yuichiro Tsuji

William & Mary Environmental Law and Policy Review

Japan’s challenge will be how quickly it can shift its energy supply to renewable energy sources. To increase energy self-sufficiency and defense power, Japan should promote policies that encourage renewable energy use. However, under the current legal system, local governments are not involved in the legal review process for establishing nuclear power plants. Through agreements, local consent is required to restart a plant. However, this is merely a contract, and permission is granted even if the agreement is violated, as long as the plant passes a safety review. The central government is trying to facilitate communication between local governments and …

Defining Womanhood: Ancient Greek Inspirations For Our Modern Ideas, Carrie Selwood

History & Classics Undergraduate Theses

What does it mean to be a woman today? Perhaps to start exploring an answer to that question, we need to look to history, to one of the cultures that has profoundly influenced our own: ancient Greece. The myths and culture cultivated by the Greeks in the first millennium BCE are of deep import to many modern societies, and they are still utilized as a common cultural touchstone for diverse populations. But what is the point of harkening back to a dead civilization from two thousand years ago to talk about modern womanhood? What can those women, the real ones …

Courtroom Workgroup Dynamics And Implementation Of Three Strikes Reform, Elsa Y. Chen, Emily Chung, Emily Sands

Political Science

In 2012, California's voters passed a ballot initiative that scaled back the state's “Three Strikes” sentencing law and permitted certain individuals who were serving 25-to-life prison terms to petition for resentencing and potentially release. Using analysis of original qualitative interview data supplemented with court administrative records, this study examines how characteristics of courtroom workgroup members; their intergroup dynamics; political, professional, and administrative considerations; and allocated resources were perceived by court officials to facilitate or impede the implementation of this reform in county courts. Availability of staff and budget was associated with a higher proportion of completed case dispositions in the …

Low Cost Magnetometer Calibration And Distributed Simultaneous Multipoint Ionospheric Measurements From A Sounding Rocket Platform, Joshua W. Milford

Doctoral Dissertations and Master's Theses

Low-cost and low-size-weight-and-power (SWaP) magnetometers can provide greater accessibility for distributed simultaneous measurements in the ionosphere, either onboard sounding rockets or on CubeSats. The Space and Atmospheric Instrumentation Laboratory (SAIL) at Embry-Riddle Aeronautical University has launched a multitude of sounding rockets in recent history: one night-time mid-latitude rocket from Wallops Flight Facility in August 2022 and three mid-latitude rockets from White Sands Missile Range during the October 2023 annular solar eclipse. All rockets had a comprehensive suite of instruments for electrodynamics and neutral dynamics measurements. Among this suite was one science-grade three-axis fluxgate magnetometer (Billingsley TFM65VQS / TFM100G2) and up …

Synchronized Bionic Hand: Harmonizing Robotics With Rhythm, Deven Ayambem , '24

Senior Theses, Projects, and Awards

This report explores the therapeutic potential of rhythmic movement to music, focusing specifically on the "wave dance" movements of the human hand. Utilizing a mechanical analog, the study models the hand as a system of five interconnected mass-spring-dampers to simulate the dynamic and kinematic responses of the hand's joints to rhythmic stimuli. Through a combined approach of MATLAB simulation and physical modeling with servo motors controlled by Arduino, the project aims to quantify and visualize the effects of rhythmic movements on joint dynamics. The simulation employs the mass-spring-damper system to represent each joint and uses an impulse response approach to …

Myoelectric Robotic Hand To Play Guitar, Oliver Garcia , '24

Senior Theses, Projects, and Awards

Around 5.6 million people in the US have had an amputation or were born with limb difference. Some of these people find prostheses to be useful devices that allow them to perform desired activities that would otherwise be difficult or impossible to carry out. One form of prosthetic that, as far as I have found, has not been developed, is one for fretting chords on a guitar. Such a prosthetic would require multiple degrees of freedom for each finger, fine motor control, as well as quick actuation and signal interpretation. Most general purpose robotic prostheses today are either far too …

Establishing Practical Equivalence Of Factor Loadings In Multigroup Confirmatory Factor Analysis, Christopher Edward Shank

Dissertations

This dissertation compares the performance of equivalence test (EQT) and null hypothesis test (NHT) procedures for identifying invariant and noninvariant factor loadings under a range of experimental manipulations. EQT is the statistically appropriate approach when the research goal is to find evidence of group similarity rather than group difference; despite this, the conventional approach to measurement invariance analysis relies upon NHT. EQT has proved effective for invariance detection using global model-data fit statistics in simulated and real-world data (Counsell et al., 2020) but its use in partial measurement invariance (PMI) analysis for evaluation of factor loading differences between groups has …

Circumventing The Fourth Amendment: The Unconstitutional Nature Of Geofence Warrants, Shelby Stender

Utah Law Review

Federal and state law enforcement agencies are using a new tactic for gathering evidence: geofence warrants. These warrants allow law enforcement to gather historical location data collected by third party companies including Google, Facebook, Amazon, and Apple. Armed with a geofence warrant today, law enforcement agencies can track the previous location of an individual at any point from the moment they acquired a cell phone—so long as the location history is turned on. The tactic has grown in popularity since 2019 and has been used to uncover suspects in cases where police had few leads. Troublingly though, the tactic has …
