Isolating Confounding Abiotic And Biotic Effects On The Phenotype On Physa Acuta Snails, Ashley M. Bauer

Theses and Dissertations

Organisms match their phenotypes to prevailing environmental conditions leading to habitat specific polymorphisms. Polymorphisms arise from genetic divergence, phenotypic plasticity, or a combination of both processes. I examined the presence of habitat-specific polymorphism in Physa acuta snails collected from three streams and their corresponding downstream reservoir. In lotic systems shells were rotund with larger apertures, while those from lentic systems were more elongate with smaller apertures. In a reciprocal transplant lab experiment that crossed flow regime and crayfish predator cues, I tested for the underlying mechanisms responsible for the observed phenotypic differences. I found no evidence for plasticity in relation …

Rural Realities Unveiled: Non-Certified Teachers’ Experiences And Perceptions Of Scripted Literacy Curriculum In K-5 Classrooms, Amillia Woolfork

Theses and Dissertations

The persistent shortage of certified teachers in rural school districts has led to an increased reliance on non-certified teachers NCTs to deliver literacy instruction. To support these educators, many districts have implemented scripted curricula, which provide structured lessons and instructional materials. However, limited research exists on the experiences of NCTs using scripted curricula and their impact on their teaching practices and self-efficacy. This qualitative exploratory case study examines the perceptions and lived experiences of non-certified literacy teachers in rural elementary schools who utilize scripted curricula. Guided by Bandura’s Self-Efficacy Theory and Kolb’s Experiential Learning Theory, this study examined how NCTs …

Comparative Analysis Of Lipid Accumulation And Antioxidant Responses In Masld And Control Ipsc-Heps, Anna Werts

CMC Senior Theses

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent liver condition characterized by lipid accumulation and associated inflammation, driven by genetic, environmental, and metabolic factors. Much is still unknown about the mechanisms of the disease, and research on this is important for advancing effective treatments. This study investigated lipid accumulation and oxidative stress responses to varying concentrations of oleic acid (OA) and palmitic acid (PA) in induced pluripotent stem cell-derived hepatocytes (iPSC-Heps) from MASLD and healthy donors. BODIPY staining revealed that MASLD iPSC-Heps exhibit significantly higher lipid accumulation than controls, especially under prolonged OA and PA exposure. Additionally, PLIN2 expression …

Trade Tensions And Consumer Decisions: Evidence From Taxable Sales During The 2018 Us-China Trade War, Eddie Wei

CMC Senior Theses

This paper examines the consumption response to the 2018 US-China trade war. While prior research has largely focused on economic outcomes such as export values, income, and employment, trade policies may also have salient distributional consequences for consumption. On one hand, import tariffs may boost well-being in regions with greater employment in protected sectors, such as manufacturing. On the other hand, retaliatory tariffs may raise prices overall and depress consumption in areas more reliant on the Chinese market, such as agriculture. To explore these dynamics, I construct a novel dataset of county-level taxable sales, capturing both household and business spending. …

The Sword, The Purse, And The Pen: The Constitutional Conundrum Of Impoundment, William N. Chance

CMC Senior Theses

This Thesis explores the constitutional conundrum of executive impoundment, the practice by which the President of the United States withholds or delays the expenditure of funds appropriated by Congress. Although impoundment has deep historical roots dating back to the Constitution’s Framers, its modern use raises profound questions regarding our separation of powers. This Thesis establishes a functional framework that distinguishes between “routine” impoundments, which promote administrative efficiency, and “policy” impoundments, which may undermine congressional intent. Furthermore, after tracing the development of impoundment from the early Republic through the Nixon Administration and the passage of the Impoundment Control Act of 1974, …

Lawyers And Public Service: Duty, Faith, And The 'Good Republican' In The West Wing, Andrew Flavelle Martin

Articles, Book Chapters, & Popular Press

Popular culture reveals much about the perceived role of lawyers in contemporary life. In this article, I draw lessons from the portrayal of lawyers in Aaron Sorkin's classic television series, The West Wing. As a drama centred around a Democratic presidential administration, Republicans often provide the foil. From time to time, however, the show lionizes what might be termed ‘the good Republican’. That ‘good Republican’ is most often a practicing lawyer whose desire to serve is grounded in duty or faith. In this essay, I use a trio of these characters to explore the role of lawyers in public service. …

Is This Cultural Property Law?: The Emerging Norm Of Voluntary Repatriations, Erin L. Thompson

Chapman Law Review

As the public’s awareness of the histories of theft and smuggling that brought many cultural artifacts from their communities of origin to American collections has grown, attitudes toward the ethics of retaining these artifacts has also shifted. This presentation will first consider challenges posed by existing legal remedies available for source countries who seek to reclaim their heritage and then discuss the emerging practice of voluntary repatriations, which occur when the current owner of an artifact returns it to a source country or community even though legal authorities would likely not compel its surrender.

The Open Apex Challenge: A Case Series, Joseph C. Stern D.D.S.

The New York State Dental Journal

Aim: To describe different endodontic techniques for managing immature necrotic teeth. Managing immature necrotic teeth has always posed challenges because of the unpredictable nature of treating roots with wide open apices that lack an apical stop. Traditionally, treatment involved placement of long-term calcium hydroxide, which was often tedious and required multiple visits. Compliance was frequently an issue, especially since many patients in this category are children and as a result, many teeth were lost due to infection or fracture. Recently, with the introduction of more biocompatible materials, a shorter treatment approach has been advocated using calcium silicate materials, such as …
