Closing Educational Gaps: One Inquiry Experience At A Time, Caroline Soliman

2023 Spring Honors Capstone Projects - Archive

Learning is a large component of everyday life, with most occurring in an educational setting. As students navigate the school system year after year, existing educational gaps increase. This study observed inquiry learning techniques in the classroom to assist students in making connections with new and previous knowledge while helping students understand the new material they are learning. Students across multiple classes in the same grade and school were taught their regularly scheduled lesson plan, but it was designed as an inquiry lesson plan. The students then wrote down what they observed/ learned and any connections they made. Those journal …

Just Extracurriculars?, Emily Gold Waldman

Elisabeth Haub School of Law Faculty Publications

Extracurricular activities have been the battleground for a striking number of Supreme Court cases set at public schools, from cases involving speech to religion to drug testing. Indeed, the two most recent Supreme Court cases involving constitutional rights at public schools--Kennedy v. Bremerton School District (2022) and Mahanoy Area School District v. B.L. (2021)--both arose in the extracurricular context of school sports. Even so, the Supreme Court has never fully clarified the status of extracurricular activities themselves. Once a school offers an extracurricular activity, is participation merely a privilege? Does the fact that extracurricular activities are voluntary for students affect …

Re-Regulating Dietary Supplements, Jessie L. Bekker, Alex Flores, Michael S. Sinha

Journal of Food Law & Policy

In 1994, Congress introduced the Dietary Supplement Health and Education Act (DSHEA) to create a regulatory framework for the dietary supplement industry. Despite the increased market size of dietary supplements, the Food and Drug Administration’s (FDA) pre-market authority to regulate the introduction of dietary supplements into the stream of commerce has remained subdued. Under DSHEA, the FDA has limited authority to review dietary supplements before entering the market. Unlike pharmaceuticals, which must be proven safe and effective prior to approval and marketing, dietary supplements can be sold to consumers without such reassurances. We call on Congress to amend DSHEA to …

Growing Agriculture Literacy’S Presence In America’S Classrooms, Emily Stone

Journal of Food Law & Policy

“Americans, as a whole, were at least two generations removed from the farm and did not understand even the most rudimentary of processes, challenges, and risks that farmers and the agricultural industry worked with and met head-on every day.” This quote perfectly describes the mindset of agriculture stakeholders in 1981 as they began to realize the drastic steps our education system had taken away from using principles of agriculture in K-12 education. As they saw it, Americans were moving out of rural America, away from farms, and becoming less connected to the food they daily consumed. Simultaneously, the education system …

The Contradictory Nature Of U.S. Laws And Nutrition Programs And Their Effects On Infant Feeding, Lily Patel

Journal of Food Law & Policy

The contradictory nature of U.S. laws, including the laws concerning infant feeding, though supposedly aligned with policies to promote wellness in Americans, can exacerbate gender and race inequality and work against the National Strategy. The overarching goal of U.S. laws concerning infant feeding is to ensure that infants are fed, nourished, and receive proper nutrition. However, the laws often appear to be directly contradictory to one another in the priorities they are promoting.

Up To Code: Lessons Learned In Evaluating And Improving Legacy Irs, Frances Chang Andreu

Articles

Not all repositories are created under ideal circumstances, and inheriting an institutional repository can present challenges distinct from building one from scratch. Changes in institutional vision, policies, and priorities can lead to inconsistent content and limited metadata. Lack of documentation and loss of institutional memory can result in uncertainty about previous decisions. This case study examines the process of auditing a legacy institutional repository in order to ensure the content best reflects the institution’s current goals and policies.

Ethanol Dysregulates Sirt1-Mediated Lipogenic Signaling Pathways Through Α4*-Nicotinic Acetylcholine Receptors In Hepatocytes., Caitlin Christina Wilkerson

Electronic Theses and Dissertations

Alcohol-associated liver disease (ALD) is a broad spectrum of diseases ranging from steatosis to severe hepatic cirrhosis, none of which have any FDA approved therapies. Downregulation of hepatic Sirtuin 1 (Sirt1) activity by ethanol has been shown to lead to an upregulation of the pro-lipogenic gene targets under its jurisdiction, resulting in increased lipogenesis and triglyceride accumulation. It was hypothesized that ethanol acts on α4*-nicotinic acetylcholine receptors (α4*-nAChRs) in hepatocytes to decrease Sirt1 expression, which ultimately dysregulates lipid metabolic homeostasis. Ethanol’s effects were investigated in cultured AML12 hepatocytes and in WT primary mouse hepatocytes acutely exposed to ethanol. Consistent with …

Environmental Exposures And Aging., Daniel Chris Gomes

Electronic Theses and Dissertations

In recent years, research into air pollution has shown that exposure to certain components in air pollution, primarily PM2.5 can accelerate biological aging and thereby lead to increased susceptibility to multiple diseases. We hypothesize that prolonged exposure to air pollutants can result in premature aging leading to extensive tissue dysfunction and susceptibility to diseases. To examine this, we exposed mice to PM2.5 for 9, 15, and 21 days, then measured the telomere lengths, cellular senescence, and histone methylation patterns of multiple cell types. We found consistently increased telomere attrition, cellular senescence and advanced age-consistent histone methylation patterns in groups exposed …

Study Of The Effects Of Chronic Cadmium Exposure On The Pathogenesis Of Pulmonary Arterial Hypertension., Dakotah Dominique Cathey

Electronic Theses and Dissertations

We reported pulmonary artery hypertension (PAH) patients had elevated levels of Cd in both blood and urine, therefore, this study tested whether Cd directly induces PAH or facilitates PAH pathogenesis in mouse models. C57/6J mice were initially exposed to drinking water with or without 5ppm Cd for 8 weeks. Then, half the mice in both control and Cd groups were given SU5416 and hypoxia (SuHx) for 4 weeks to induce PAH, resulting in 4 subgroups: Control, Cd, PAH, and Cd+PAH. Diastolic and systolic functions of the left and right ventricles (LV, RV) were examined with echocardiography before and after PAH. …

Genetically Engineering Gingipains For High Yield Large Scale Purification., Andrew E. Fuchs

Electronic Theses and Dissertations

Porphyromonas gingivalis is a keystone oral pathogen in the progression of periodontal disease and has been implicated in the etiology of many other systemic human diseases. P. gingivalis produces primary virulence factors termed the gingipains, a group of cysteine proteases. There is a high demand for high purity gingipains for downstream in vitro studies where P.g. is implicated, both oral and systemic. Gingipain production candidate mutant P.g. strains were generated to isolate each gingipain for large scale purification and the purified gingipains characterized. Two mutants were determined not to be viable for large scale purification of gingipains, each for different …

The Interplay Between Lung Adenocarcinoma, Nutrient Availability, And The Microbiome., Alexis A. Vega

Electronic Theses and Dissertations

Lung cancer is one of the most common forms of cancer diagnosed, and has the highest lethality rate across all other forms of cancer in the U.S. While current therapeutic options include chemo-, immuno-, and radio-therapy, the benefits of caloric or nutrient restriction on cancer cells has also been investigated. Due to the many biological functions associated with methionine, many have proposed a methionine restricted diet would lead to favorable outcomes when combating cancer. Although our cells are incapable of synthesizing methionine, the bacteria found in our microbiome can. Furthermore, recent discoveries suggest an independent microbiome found within tumors that …

Quantification Of Tumor Biophysical Heterogeneity Through Mechanical And Ultrastructural Analysis., Bradley James Mahaffey

Electronic Theses and Dissertations

Glioblastoma (GBM) is a highly invasive, aggressive brain cancer that carries a median survival of 15 months. This poor prognosis is due, in part, to its resistance to standard therapeutic intervention. Recent studies have demonstrated that tumor heterogeneity plays a critical role in facilitation therapy resistance by mediating tumor adaptation through microenvironmental cues. Efforts to describe these microenvironmental differences may aid in the development of strategies to combat resistance. GBM can be separated into two distinct regions – a core and a rim, which are thought to drive specific aspects of tumor evolution. The core is proliferative as evidenced by …

Investigation Of Heterocyclic Amines And N-Acetyltransferase 2 Genetic Polymorphism In The Dysregulation Of Hepatic Energy Homeostasis: A Gene-Environment Approach., Kennedy M Walls

Electronic Theses and Dissertations

Heterocyclic amines (HCAs) are mutagens generated when cooking meat for prolonged periods of time or until well-done. Recent epidemiological studies reported significant associations between dietary HCA exposure and insulin resistance and type II diabetes. However, no previous studies have examined if HCAs, independent of meat consumption, contributes to pathogenesis of insulin resistance or metabolic disease. It is well known that HCAs require hepatic bioactivation by cytochrome P450 1A2 (CYP1A2) and N-acetyltransferase 2 (NAT2). NAT2 expresses a well-defined genetic polymorphism in humans that, depending on the combination of NAT2 alleles, correlate to rapid, intermediate, or slow acetylator phenotypes that exhibit differential …

Impact Of Weather Factors On Airport Arrival Rates: Application Of Machine Learning In Air Transportation, Robert W. Maxson, Dothang Truong, Woojin Choi

Publications

Weather is responsible for approximately 70% of air transportation delays in the National Airspace System, and delays resulting from convective weather alone cost airlines and passengers millions of dollars each year due to delays that could be avoided. This research sought to establish relationships between environmental variables and airport efficiency estimates by data mining archived weather and airport performance data at ten geographically and climatologically different airports. Several meaningful relationships were discovered from six out of ten airports using various machine learning methods within an overarching data mining protocol, and the developed models were tested using historical data.

Possible Futures For Colonial Collecting Institutions: A Study Of Historical Societies In The United States, Jen Hoyer

Publications and Research

This article explores how collecting institutions with deeply colonial roots can move into a decolonial future existence, through an in-depth study of historical societies in the United States. Examining their historic roots in colonialism of the United States and the persistence of these colonial identities in spite of a variety of evolutionary trends over the 20th century, this article asks: what decolonial possibilities exist for their future? If institutional shifts have not undone the colonial identities of some collecting institutions, what can? Turning to Sarah Ahmed’s theory on queer use and Saidiya Hartman’s method of critical fabulation, I suggest practical …

Improving Lawyers & Lives: How Immigrant Justice Corps Built A Model For Quality Representation While Empowering Recent Law School And College Graduates And The Immigrant Communities Whom They Serve, Jojo Annobil, Elizabeth Gibson

Fordham Law Review

The late Judge Robert A. Katzmann of the U.S. Court of Appeals for the Second Circuit formed a study group in 2008 called the Study Group on Immigrant Representation to assess the scope of the problem and find a solution. The study group determined that the representation crisis was an issue “of both quality and quantity” and that the two most important variables for a successful outcome in a case were having counsel and not being detained. To address this need, the study group established two innovative programs: the New York Immigrant Family Unity Project (NYIFUP), the first public defender …

Jimenez-Vergara, Jacob Avina, Travis Jackson Block, Anne Sheldrake, Carson Koch, Anna Gonzalez, Jennifer Steele, Ana M. Díaz-Lasprilla, Dany J. Munoz-Pinto

Engineering Faculty Research

The repair of neuronal tissue is a challenging process due to the limited proliferative capacity of neurons. Neural stem cells (NSCs) can aid in the regeneration process of neural tissue due to their high proliferation potential and capacity to differentiate into neurons. The therapeutic potential of these cells can only be achieved if sufficient cells are obtained without losing their differentiation potential. Toward this end, an astrocyte-derived coating (HAc) was evaluated as a promising substrate to promote the proliferation of NSCs. Mass spectroscopy and scanning electron microscopy were used to characterize the HAc. The proliferation rate and the expression of …
