Treatment Of Anxiety By Transcutaneous Vagus Nerve Stimulation: A Retrospective Chart Review, Rhea Gandhi

CMC Senior Theses

Surgical vagus nerve stimulation (VNS) was FDA cleared for depression (2005) and epilepsy. (1997). In the surgical procedure, a pacemaker is implanted below the collarbone (clavicle) and connected to the vagus nerve in the neck. Transcutaneous vagus nerve stimulation (tVNS) is a non-surgical alternative to VNS and there is evidence supporting its effectiveness for several conditions. Advantages include lower cost and fewer adverse side effects.

Anxiety is tied to excess or unopposed sympathetic nervous system activity, while the parasympathetic nervous system, especially the vagus nerve, is relatively underactive. This study aimed to investigate a potential impact of regular tVNS stimulation …

Modern-Day Hearing Impairment: The Role Of Environmental Factors And Lifestyle Choices, Hassan Majeed

CMC Senior Theses

This thesis explores the increasingly prevalent issue of hearing impairments in the context of modern environmental factors and lifestyle choices. The intricate workings of the human auditory system are first examined, emphasizing its complexity and sensitivity. The study delves into the categories of hearing impairments - conductive and sensorineural - highlighting their distinct characteristics, causes, and impacts on individuals' lives. A key focus of the research is the influence of environmental factors, particularly the escalating problem of noise pollution in urban and industrial settings. Studies show that prolonged exposure to high decibel levels significantly deteriorates hearing acuity. Other environmental risks, …

The Role Of Herbal Medicines In Central American Indigenous Communities; Improving Accessibility To Type 2 Diabetes Mellitus Treatment, Sarai Ortega

CMC Senior Theses

Indigenous communities in Central America have used various plant medications to treat illnesses and diseases for centuries. Clinicians must consider improving traditional healthcare methods that are intrinsic to indigenous communities in order to increase access to effective treatments, particularly for diseases that these communities are more at risk for. This work aims to propose a method to identify whether traditional preparations of five plants (Anacardium occidentale L., Hamelia patens Jacq., Momordica charantia L, Neurolaena lobota L. R. Br. Ex Cass., and Tecoma stans L. juss. ex Kunth) can reduce blood glucose levels in rats with type two diabetes. Additionally, …

The Relationship Between Parasite Infection, Body Condition, And Migration In White-Crowned Sparrows And California Towhees, Madeline Galbraith

CMC Senior Theses

Long-distance animal migration plays a large role in the spread of infectious disease, potentially causing an increase or a decrease in infection. These outcomes can be serious, as infection has the ability to induce a variety of effects on the host, all which may impact their overall health. The consequences of infection on a host can be measured using body condition. Changes to an individual’s body condition are central to the mechanisms involved in migration’s ability to both increase (ex: susceptibility) and decrease infection (ex: migratory culling). Therefore, when assessing potential migratory effects, it is important to consider relationships between …

A Philosophical And Empirical Investigation Into Buddhist Economics, Hannah Doyle

CMC Senior Theses

There is a growing body of literature on Buddhist economics from a philosophical perspective; however, no work to date has sought to empirically validate it as an effective economic theory at a global scale. In my paper, I draw on the long history of Buddhist metaphysics to construct an account of Buddhist ethics and then proceed to derive a set of Buddhist economic principles. I draw on the World Happiness Report’s methodology to quantitatively demonstrate the relationship between Buddhist economic principles and the psychological wellbeing of a country’s citizens, as measured through their own evaluation of their quality of life …

The Relationship Between Body Mass Index And Depression In College Students, Bryn Kable

CMC Senior Theses

College student mental health has seen a serious decline over the last decade (Esaki-Smith, 2022). One factor that has been linked to both physical and mental disorders is obesity. A common way to operationalize weight is through body mass index (BMI) (Ilman et al., 2015). There is evidence that BMI and depression are correlated linearly in that individuals with higher BMIs have higher levels of depression (Badillo et al., 2022; Simon et al., 2008). The exact mechanisms of this relationship are still generally unknown; thus, the goal of this study was to investigate the relationship between BMI and depression in …

Psychedelic-Assisted Therapy: Support For The Rebus Hypothesis And Its Application To Specific Psychiatric Illnesses, Wren Cilimburg

CMC Senior Theses

For centuries, psychedelic substances have been a part of human culture. Classic psychedelics such as LSD and psilocybin are characterized by their agonism of 5HT-2A receptors, and recent clinical trials have found that these substances hold great promise for treating mental disorders. Neurobiological evidence supports the recent theory that psychedelic-assisted therapy works by increasing neuroplasticity and allowing for the revision of maladaptive predictions. This theory is called the REBUS hypothesis, and it is situated within a predictive processing model of cognition. There is evidence that individuals with mental disorders such as depression, addiction, and eating disorders have a diminished ability …

Balancing Trade And Security During The Us-China Trade War: A Gravity Model Approach To South Korea’S Relations With The United States And China, Nathalie Chavez

CMC Senior Theses

In analyzing monthly trade and gross domestic product (GDP) data for South Korea, China, and the United States from January 2016 to December 2019, this paper attempts to quantify the effects of the US-China Trade War on Korea’s security and economic considerations. By using a three-country gravity model with both monthly and HS Code (harmonized system) fixed effects, it finds the following. First, increases in both real GDP for the United States and China, as well as real GDP for Korea, are positively associated with increases in Korean exports at statistically significant levels. Thus, the general predictions of the gravity …

Revisiting The 2018 Corsica Oil Spill - A Preliminary Case Study Of Ecosystem Recovery From Pahs In Yelkouan Shearwater (Puffinus Yelkouan), Makenna Mahrer

CMC Senior Theses

Polycyclic aromatic hydrocarbons (PAHs) are a specific class of persistent organic pollutants (POPs) heavily associated with crude oil, and pose genotoxic and physiological threats to marine life when released into the aquatic environment during a petroleum spill. This study seeks to understand the residual impacts of the 2018 Corsica oil spill on Puffinus yelkouan (Yelkouan Shearwater), a seabird endemic to the Mediterranean basin, using the species as a bioindicator for contamination in the region. Though classified by the IUCN Red List as ‘vulnerable,’ this species remains grossly understudied in present monitoring literature. This study made use of blood samples and …

The Gay Science: Power On The Body, Population, And Psyche, Nicola Augustyn

CMC Senior Theses

Michel Foucault is a philosopher of power who left behind a legacy of ideas that continue to inspire scholars today. His conceptualization of power is not limited to the figures of kings, monarchs, or the sovereign state. Rather, he regards power as a productive force that shapes subjectivity, manufactures knowledge, and engenders the truth in a particular historical context. In this thesis, I aim to provide a comprehensive account of Foucault’s analysis of power, starting with his refutation of the “repressive hypothesis” that challenges the predominant view of centralized top-down power. Then, I present Foucault’s proposal for redefining power as …

Mysteries Of The Gothic, Addison Duvall

CMC Senior Theses

By examining the histories of the Notre-Dame and Chartres cathedrals, I will consider three academic schools of thought regarding the high Gothic Cathedrals: the balanced and rational feat of engineering, the communal and social rituals that bond humans to this space, and the iconographic manifestation of the supernatural. Functionalist engineering paradoxically lays at the heart of these cathedrals' capacity to open the human consciousness to the sacred by using recurrent symbolic patterns from nature, music and mathematics to create divine ratios that transport us. Integrated into these larger architectural designs the repeating visual patterns exalting both biblical and supernatural icons …

Effects Of Male Attractiveness On Prostaglandin E2 Production Levels, Kyra Cousins

CMC Senior Theses

Sexual conflict or sexual antagonism can encourage co-evolution between males and females of a given species. In house crickets (Acheta domesticus), unattractive (smaller) and attractive (larger) males seem to use differential allocation of prostaglandin E₂ in their spermatophore to pursue different propagation strategies in influencing female oviposition. This study aims to determine the means by which attractive and less attractive males press their reproductive advantage by focusing on prostaglandin E₂. To test the hypothesis that the difference in prostaglandin E₂ concentration is essential for female reproductive manipulation, spermatophores were retrieved from 21 pairs of mated …

Toward Principled Background Principles In Takings Law, Rebecca Hansen, Lior Jacob Strahilevitz

Coase-Sandor Institute for Law & Economics Research Paper Series

Blunders made by lawyers, judges, and scholars have caused the Supreme Court’s recent opinion in Cedar Point Nursery v. Hassid to be deeply misunderstood. In Cedar Point, the Court re-wrote takings law by treating temporary and part-time entries onto private property as per se takings. Prior to Cedar Point these sorts of government-authorized physical entries would have been evaluated under a balancing framework that almost invariably enabled the government to prevail. As it happens, there were two well-established rules of black letter law that California’s lawyers and amici mistakenly failed to invoke in defending the Cedar Point union organizer access …

Regulatory Trading, David A. Weisbach

Coase-Sandor Institute for Law & Economics Research Paper Series

Regulatory trading systems, such as the SO2 cap and trade system, are ubiquitous in environmental and natural resources law. In addition to cap and trade systems for pollutants such as SO2, NOx and CO2 , environmental and natural resources law uses trading in areas such as endangered species, water quality, wetlands, vehicle mileage, and forestry and farming practices. Trading, however, is rarely used as a regulatory approach in other areas of law. This paper seeks to identify the reasons for this dichotomy. To understand the dichotomy, the paper examines the uses of trading in environmental and natural resources law, where …

Residents Against Housing, Lee Anne Fennell

Coase-Sandor Institute for Law & Economics Research Paper Series

Incumbent residents routinely oppose residential development.¹ Interestingly, this is true of both homeowners and renters, if for opposite reasons. Homeowners typically worry that new housing will cause the market value of their own homes to fall, resulting in a hit to what is usually a house-heavy personal wealth portfolio.² Tenants typically worry that new housing will cause the market value of their own homes to rise, generating pressure toward higher rents and displacement.³ Both homeowners and tenants also express concern that new housing development will change the character of their neighborhoods in unwanted ways.⁴

Resident opposition …

Property As Service Streams, Lee Anne Fennell

Coase-Sandor Institute for Law & Economics Research Paper Series

Property’s job is to help people derive benefits from resources.¹ But often it cannot do this work well. A core problem is an outmoded model of benefit production that treats the individually owned parcel or “thing” as the relevant unit of analysis.² Property theorists often use the example of a farm to illustrate how ownership induces people to invest (in sowing) by granting them exclusive rights (to reap the crops).³ On this account, property holdings operate in a largely self-contained fashion, collecting inputs from owners and delivering the associated returns to them. The primary role of property …

Cross-Border Influencers: Democracy And Externalities, Saul Levmore

Coase-Sandor Institute for Law & Economics Research Paper Series

The United States does not allow foreigners to influence U.S. elections by giving money to political parties or candidates, but many other countries do allow cross-border influencing. Indeed, the variety of policies among countries is remarkable. Some countries, like the United States, that forbid financial contributions from outside the country, do permit cross-border contributions across domestic borders, such as those of states and cities. Meanwhile, Canadians cannot contribute to the campaigns of U.S. political candidates, and cannot even (lawfully) influence the American political process by purchasing campaign t-shirts or bumper stickers. This prohibition is in place even though, like constituents …

Serotonin Regulation Of Behavior Via Large-Scale Neuromodulation Of Serotonin Receptor Networks, Piergiorgio Salvan, Madalena Fonseca, Anderson M. Winkler, Antoine Beauchamp, Jason P. Lerch, Heidi Johansen-Berg

School of Medicine Publications

Although we understand how serotonin receptors function at the single-cell level, what role different serotonin receptors play in regulating brain-wide activity and, in turn, human behavior, remains unknown. Here, we developed transcriptomic–neuroimaging mapping to characterize brain-wide functional signatures associated with specific serotonin receptors: serotonin receptor networks (SRNs). Probing SRNs with optogenetics–functional magnetic resonance imaging (MRI) and pharmacology in mice, we show that activation of dorsal raphe serotonin neurons differentially modulates the amplitude and functional connectivity of different SRNs, showing that receptors’ spatial distributions can confer specificity not only at the local, but also at the brain-wide, network level. In humans, …

Effect Of Low-Level Laser On Miniscrew Displacement During Canine Retraction: A Randomized Controlled Clinical Trial, Aly Osman, Nadia El Harouni, Mohamed Shokry

International Arab Journal of Dentistry

Background: Anchorage is an important consideration for successful orthodontic treatment. Skeletal anchorage by miniscrews provided better anchorage control then the ordinary extra-oral and intra-oral appliances. However, the stability of the miniscrews is still questionable since they might move under orthodontic loading.

Objectives: The aim of this study was to evaluate the effect of Low Level Laser on the miniscrew displacement when subjected to orthodontic force during canine retraction using CBCT.

Methods: Twelve patients who required bilateral extraction of upper first premolar and absolute anchorage were recruited from the outpatient clinics of the Department of Orthodontics, Faculty of …

Fostering Infant And Toddler Music Competence At The Jean Tyson Child Development Study Center, Ellen Mathews, Laura Herold, Shelley Mcnally, Donia Timby

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

This paper presents a creative research project that introduced musical instruments in an outdoor setting to infants and toddlers ages 0-to-3 years old. It was grounded in research suggesting that music plays a vital component in expanding development in the early childhood years, helping to promote learning across many domains. This project began with a survey distributed to 7 infant and toddler classroom educators, after which responses were analyzed for themes regarding perceived infant interests. Subsequent observations were conducted to evaluate the best fit for the implementation of an outdoor experiential music space. Based on the findings, a developmentally appropriate …

Energy Content Of Grasshoppers (Orthoptera: Acrididae) In The Diet Of Scaled Quail (Callipepla Squamata) In Southeastern New Mexico, J.L. Hunt, M.E. Grilliot, T.L. Best, C.M. Wilkerson, A.F. Huitt

Journal of the Arkansas Academy of Science

Grasshoppers (Orthoptera: Acrididae) are common insects that are important food items for many kinds of wildlife, including many species of upland game birds such as scaled quail (Callipepla squamata). We analyzed the energy content of grasshoppers obtained from the crops of scaled quail collected from plainsmesa sand-scrub in Lea and Eddy counties, New Mexico. Grasshoppers were removed from crops and dried for 48 hours at 60°C to remove moisture and standardize masses. Grasshoppers were then pulverized and analyzed for gross caloric value (i.e., energy content) in an oxygen bomb calorimeter. Energy content of grasshoppers from New Mexico averaged 19.2 J/kg …

Alexander Von Humboldt: Explorer, Naturalist, And Environmental Pioneer (2019) By Danica Novgorodoff, Peter Shea

Picture Books

As a young boy, Alexander Von Humboldt came up with divergent questions about the birds and mountains and animals he saw, and brought all those questions together under two big questions that stayed important for him over a long life: “How are these things different?” and “How are they nevertheless connected?” As the reader watches Humboldt looking at a hawk and a mouse, volcanoes and farmland, palm trees and pine trees, Europe and Ecuador, Europeans and Indigenous people, one comes to expect what he will say: “They are different, and yet they are connected.” This idea is much bigger than …
