Evaluation of Transcranial NIR Light Propagation for Photo-biomodulation of Neurons Using Mesh-Based Monte Carlo ModelingResearch has shown that photo-biomodulation of neurons with near-infrared (NIR) light can stimulate their regeneration, and thus various research groups have developed devices that emit NIR light transcranially (through the skull) to stimulate neural growth in the brain in an effort to treat neurological diseases such as Multiple Sclerosis (MS) and Alzheimer’s. However, it is not clear that clinical device designs illuminate cells in the brain with similar parameters as those shown effective for neuro-regeneration in pre-clinical work. This project employed computational modeling and simulations to assess the effect of device design parameters on transcranial light propagation, in order to optimize illumination of brain tissue and cells and thus ultimately improve clinical results of transcranial NIR-emitting devices for neuro-regeneration. Specifically, this project consisted of the development of two computational models for transcranial NIR-emitting devices and the evaluation of three device parameters: wavelength, photon number, and power density, on transcranial NIR light propagation.

Ambiguous Attacks on Democracy in Europe and the Americas: What can intergovernmental organizations do?Past the time of traditional coups, today’s would-be dictators are seeking out more ambiguous ways to undercut democracy. These norm violations are often difficult to identify, and sometimes are conceived of as less threatening to outsiders. So, what can an intergovernmental organization do if its member states begin to violate common democratic norms in an ambiguous way? While some have claimed IGO action is determined by the violating state’s power or the pressure of third parties, few have explored the influence of an IGO’s structure and design on its decision to enforce norms. This paper explores some ambiguous measures being taken to undermine democracy, and seeks to disaggregate the complex process of IGO norm enforcement and subject the moving parts to initial scrutiny. In this paper, I assess the impact of five IGO characteristics on its decision to enforce democratic norms in member states: IGO composition or democratic density, democratic norm legalization, enforcement provisions, voting rules in the IGO’s intergovernmental branches, and delegation to the IGO’s supranational bodies. I develop six, independent hypotheses, relating one IGO characteristic to one aspect of the decision-making process. Using a pattern matching research design, I conduct a comparative case-study analysis of the Peruvian autogolpe facing the Organization of American States in 1992 and the Hungarian constitutional crisis challenging the European Union today to test each variable’s predicted effect.

Conical Intersections: The Seam Space Between the SciencesWhen molecules absorb light and become excited, the energy ultimately has to go somewhere; the energy can be lost by radiation, transferred to another molecule, or lost as heat. To predict how molecules interact with light and other matter, theoretical chemists use calculations based on the Born-Oppenheimer Approximation to numerically estimate energies and other properties of interest. Most processes can be explained within the bounds of the approximation; however, the spontaneous nonadiabatic loss of energy as heat cannot. These non- adiabatic processes are driven by conical intersections and play an important role in many known phenomena. Computationally, conical intersections rise out of the breakdown of the Born- Oppenheimer Approximation and the coupling of electronic and nuclear wavefunctions. Physically, conical intersections represent the seam space of degenerate electronic states on the potential energy surface of a molecule. Metaphorically, conical intersections represent the seam space of the research frontiers in biology, chemistry, physics, mathematics, and computer science. The present work is a review of the work in, and application of, each respective field related to conical intersections and a benchmarking study of the most viable current methods used to calculate conical intersections.

Other Worlds: A Multi-Disciplinary Portfolio of Alternative RealitiesThis project explores the human tendency of fleeing the real world and constructing a more desirable other. While the notion of creating an alternate world—worldbuilding as it is referred—may seem extremely individualistic, and therefore insular, personal worlds always have political implications and can, therefore, serve to critique larger cultural structures and societies. This paper will particularly analyze worldbuilding as an intentional process of constructing a new space without socially prescribed constraints that is in some way better than a person’s current reality. While worldbuilding is at times a survival tactic, can it simultaneously promote isolation from others? Additionally, if worldbuilding is a strategy to achieve other-worldly transcendence, what are the consequences of losing earthly ties? These questions are addressed through an exploration of the alternative worlds within the works of authors, artists, and characters of various countries and time periods, presenting the universal and timeless need to create an otherwise.

U.S. Citizen Children of Undocumented Parents: Examining Political Activism and Immigrant Generation IdentityHow do U.S. born children of undocumented parents politically act given their indirect experiences with ill-calibrated immigration policies? As immigration becomes a growing concern for undocumented communities and their mixed-status families, U.S. born children of undocumented parents may be more likely than children of U.S. citizen parents to engage in democratic activism demonstrating opposition to anti-immigrant policies. Experiencing fear of a parent’s deportation, U.S. born citizens of undocumented parents act in resistance to policies that are overly restrictive to the livelihoods of their mixed-status family and policies that appear anti-immigrant. Given their citizenship and account for a growing population in the United States, these individuals can engage in electoral politics and influence the abolition of punitive immigration laws. Little research exists addressing whether a parent’s legal status impacts the political engagement of their U.S. citizen children, despite the existence of nearly 17 million Americans living within a mixed-status family. By examining civic engagement data from first-generation children of undocumented immigrants and children of U.S. citizen parents, I will identify whether exposure to navigating “illegality” through their parents and the impact it has on their family’s livelihoods politically mobilizes them and if it surpasses the activism of their third-plus generation counterparts.

Development and Assessment of a Theater Group for People with AphasiaThe Philadelphia Aphasia Community at Temple (PACT) utilizes a group therapy approach for people with aphasia (PWA) by providing opportunities for PWA to enhance communication skills in an interest-driven setting. Recent research demonstrates how theater can improve the communication of ideas through both non-verbal and verbal means and can offer a medium through which PWA can interact and share their experiences. The main goal of this project was to examine how theater has been used with PWA and how theater games and experiences can be adapted for PWA at PACT. Existing studies were reviewed in regard to the benefits of theater for people with communication disabilities and the theories underlying different theater games. These concepts were applied to a pilot theater group at PACT. Nine PWA attended six weekly sessions throughout Summer 2019, and eight PWA attended weekly sessions throughout the Fall 2019 semester. Sessions incorporated different theater games and activities to gauge interests and skills, with support from Physical Therapy. Pre-/post-group testing included the Communication Confidence Rating Scale for People with Aphasia and a theater survey examining participant’s interests, skills, and knowledge of theater. Results from pre-test and post-test were compared to determine changes in perception of theater, enjoyment, and overall benefits of a theater group for PWA.
