Student-Developed Laboratory Activities Using Rolling Object On An Inclined Plane To Improve Student Learning, Qing Shao, Joseph Ametepe

Georgia Journal of Science

This work presents an alternative method of teaching undergraduate introductory physics laboratory. Students are presented with an experimental scenario “Rolling object on an inclined plane” and guided to develop their own laboratory activities in a studio-style setting. The overall goal of this alternative approach is to shift part of the learning responsibility to students. Through guided self-developed activities, students establish the connections between different physics concepts. Such a shift makes students active participants in the classroom, allows them to explore ideas independently, and discover through doing the exploring. Furthermore, the pedagogy is aimed at (i) motivating and actively engaging students …

Addressing Stem Gender Disparity, Liesl Carter

Line by Line: A Journal of Beginning Student Writing

I had written this piece under my English 198 class theme of gender. I wanted to explore why there is a continued gender gap in STEM. I had researched and analyzed articles that worked to explain this concept. I then conducted personal research in the form of a survey and interview to apply my findings to personal life experiences particularly at the University of Dayton. My overall writing process included research and analysis written into numerous drafts which were reviewed by both peers and my professor.

Microplastic Abundance Across Aquatic Habitats In Lake Michigan Tributaries, Audrey Eros, Olivia Schaul, Jesus Leal

Undergraduate Research and Engagement Symposium

Microplastic (<5mm) pollution is ubiquitous worldwide. The distribution of plastic particles in freshwater tributaries is ‘patchy’ showing an accumulation of particles in depositional zones, which have naturally occurring fine particles. Microplastics may be ‘sorted’ by density; denser particles in the sediment and less dense particles on the water’s surface. The purpose of this study is to determine the spatial distribution of microplastic by polymer type in 3 river habitats: surface water, water column, and benthic. So far in our study, we have found microplastics of all types can sink and become part of the sediment. Our next steps in the project are to complete the micro-FTIR analysis and compare our results to that of fish and macroinvertebrates at the same sites.

Suffering In Silence: Black Maternal Mortality And Epistemic Injustice, Yosan Lebab

Undergraduate Research and Engagement Symposium

In the United States, maternal mortality rates among Black women are disproportionately high. While complex factors such as access to healthcare and socioeconomic status influence maternal health outcomes, the ways in which physicians interact with pregnant Black women needs to be addressed. Using Miranda Fricker’s concept of epistemic injustice, I will examine interactions between physicians and pregnant Black women. Testimonial and hermeneutical injustice towards pregnant Back women is perpetuated because of biological fallacies, and implicit biases in pain treatment and patient-physician interactions. Exploring these connections allows us to shed light on the mistreatment of Black mothers in the healthcare system.

What Is The Cause Of Blue Eye Color In Humans?, Elaheh Seddiqi

Thinking Matters Symposium

Approximately 16 different genes are responsible for human eye color. This literature review will discuss some changes in one of these genes, OCA2, a major contributor to eye color. One interval on chromosome 15 which contains the OCA2 gene and the OCA2 locus is found to be responsible for an estimated 74% of the variance in human eye color. Expression of OCA2 produces P protein in melanocytes. Melanocytes produce melanin, the substance that gives the eyes their color. Two adjacent genes on chromosome 15, HERC2 and OCA2, are so close together that an intron of HERC2 contains the promoter region …

Retrospective Comparisons Of Competing Demographic Models Give Clarity From “Messy” Management On A Scottish Grouse Moor, Larkin A. Powell, Nicholas J. Aebischer, Sonja C. Ludwig, David Baines

School of Natural Resources: Faculty Publications

Retrospective comparison of predictive models that describe competing hypotheses regarding system function can shed light on regulatory mechanisms within the framework of adaptive resource management. We applied this approach to a 28-year study of red grouse (Lagopus lagopus scotica) in Scotland, with the aims of reducing uncertainty regarding important drivers of grouse population dynamics, and of evaluating the efficacy of using seasonal versus annual model assessments. We developed three sets of models that predicted pre-breeding and post-breeding grouse density, matching the timing of grouse counts on the ground. We updated conditions and management through time in the spirit …

Baseline Health And Nutritional Parameters Of Wild Sand Tigers Carcharias Taurus Sampled In Delaware Bay, Lisa A. Hoopes, Tonya M. Clauss, Bradley M. Wetherbee, Dewayne A. Fox

Marine & Environmental Sciences Faculty Articles

Species-specific hematological reference values are essential for diagnosis and treatment of disease and maintaining overall health of animals. This information is lacking for many species of elasmobranchs maintained in zoos and aquaria, thus reducing the effectiveness of care for these animals. Descriptive statistics and reference intervals were calculated for hematocrit and complete blood cell counts, biochemistry and protein electrophoresis parameters, trace minerals, vitamins, heavy metals, reproductive hormones, and fatty acids in the blood of 153 wild Sand Tigers Carcharias taurus of both sexes and a range of sizes caught in Delaware Bay (Delaware, USA). Mean hematocrit, total white blood cell …

Sexual Minority Thriving: Bouncing Beyond Adversity, Debra Crawford

Dissertations

Sexual minority individuals continue to face prejudice and discrimination due to their sexual minority identity. However, despite these negative experiences, many sexual minority individuals display resilience and thrive. Most of the literature on sexual minorities focuses on negative aspects of identifying as a sexual minority, rather than the positive qualities that these individuals possess that allow them to persevere. In a sample of 303 sexual minorities, this dissertation contained two studies. Study one investigated if posttraumatic growth mediated the relationship between resilience and thriving and if identity pride and existential anxiety moderated the relationship between resilience and thriving in a …

What Is Assertiveness?, Mirjana Trifunovic

Theses

My main aim is to define assertiveness, to distinguish assertiveness from aggressiveness, and to raise the question of whether we should be assertive. Most articles on assertiveness are from the field of psychology. In psychology, assertiveness is defined as a healthy way of expressing oneself. But what does assertiveness mean? How should we define assertiveness and is assertiveness desirable, or is it closely connected to aggressiveness? Should we say that assertiveness is a part of our character, an innate quality, or an acquired skill? In this thesis, I will define assertiveness and show how to distinguish assertiveness from aggressiveness. Most …

Coil-To-Bridge Transitions Of Self-Assembled Water Chains Observed In A Nanoscopic Meniscus, Byung I. Kim, Ryan D. Boehm, Harrison Agrusa

Physics Faculty Publications and Presentations

Ten downward portions in the large oscillatory force–distance curve reported earlier are analyzed to understand a nanoscale water meniscus confined between a sharp probe and a flat substrate in air. The sigmoidal shape of each portion leads to the assumption that the meniscus is made up of n independent transitions of two states: one for a coil state and the other for a bridge state. The analysis reveals that each downward portion occurs due to a coil-to-bridge transition of n self-assembled water chains whose length ranges between 197 and 383 chain units. The transition provides novel insights into water’s unique …

A Quantitative Study Of The Relationships Among Psychological Safety, Collaborative Capacity, And School Climate In Middle-Level Schools, Karen Brownfield

Dissertations

This quantitative study was conducted to investigate possible relationships between psychological safety, collaborative capacity, and school climate in middle level schools in order to identify specific leadership behaviors to increase collective efficacy. School leaders’ knowledge of the positive effect collective efficacy has on student learning is not enough (Donohoo & Katz, 2019; Parrett & Budge, 2020). Leaders must also be aware of functional behaviors to foster collective efficacy, thus increasing student learning (Donohoo & Katz, 2019). Based on the theoretical work of Bandura (2000, 2012), as well as DeWitt (2017), Garmston and Wellman (2013), Hattie (2017, 2019), and Rock (2013), …

The Effect Of Using The Adaptive Crawler™ On The Development Of Infants With Spina Bifida, Age 6-12 Months, Margaret E. Williams

Dissertations

During the timeframe of crawling, age 6--12 months, infants typically interact independently with their environment and their parents in order to perform certain developmental tasks. However, many infants with spina bifida are unable to crawl, as would typically developing infants. The inability to crawl may place these infants at a distinct disadvantage during this developmental timeframe. As a result of the developmental disadvantage, the parent-infant relationship may be negatively affected. For this study, the Adaptive Crawler™ assistive technology infant mobility device was designed, and a prototype created, to promote independent mobility and exploration of their environment by infants with spina …

The RB1 gene is frequently mutated in human cancers but its role in tumorigenesis remains incompletely defined. Using an induced pluripotent stem cell (iPSC) model of hereditary retinoblastoma (RB), we report that the spliceosome is an up-regulated target responding to oncogenic stress in RB1-mutant cells. By investigating transcriptomes and genome occupancies in RB iPSC–derived osteoblasts (OBs), we discover that both E2F3a, which mediates spliceosomal gene expression, and pRB, which antagonizes E2F3a, coregulate more than one-third of spliceosomal genes by cobinding to their promoters or enhancers. Pharmacological inhibition of the spliceosome in RB1-mutant cells leads to global intron retention, decreased cell …

Ror Activation By Nobiletin Enhances Antitumor Efficacy Via Suppression Of Iκb/Nf-Κb Signaling In Triple-Negative Breast Cancer, Eunju Kim, Yoon-Jin Kim, Zhiwei Ji, Jin Muk Kang, Marvin Wirianto, Keshav Raj Paudel, Joshua A Smith, Kaori Ono, Jin-Ah Kim, Kristin Eckel-Mahan, Xiaobo Zhou, Hyun Kyoung Lee, Ji Young Yoo, Seung-Hee Yoo, Zheng Chen

Triple-negative breast cancer (TNBC) is a heterogeneous disease characterized by poor response to standard therapies and therefore unfavorable clinical outcomes. Better understanding of TNBC and new therapeutic strategies are urgently needed. ROR nuclear receptors are multifunctional transcription factors with important roles in circadian pathways and other processes including immunity and tumorigenesis. Nobiletin (NOB) is a natural compound known to display anticancer effects, and our previous studies showed that NOB activates RORs to enhance circadian rhythms and promote physiological fitness in mice. Here, we identified several TNBC cell lines being sensitive to NOB, by itself or in combination. Cell and xenograft …

Assessing Augmented Reality Instruction In Manufacturing Engineering Education, Janine Draper Price

Theses and Dissertations

Augmented Reality (AR) is fast-growing technology that has proved itself in many applications, including manufacturing environments. Manufacturing engineers benefit in an industrial environment by harnessing this technology in the workplace to guide workers through a variety of tasks. It is no longer a question on whether it is useful, but what are the best ways of applying the technology. Currently there are no published studies on ways to use augmented reality in a Manufacturing Engineering Educational Environment (MEEE). This study examines various ways that AR can be used in an MEEE setting and assesses the value of such applications. This …

Interwar Weimar Film And Masculinity: Challenging The Presumed Crisis Of Interwar German Gender Discourse From Selected Films From 1925-1931, Brandon Metcalf

Dissertations and Theses

The First World War altered the view of masculinity held by many in Germany and shredded what many regarded as unchangeable fixtures of German life. For German men, much of the interwar period meant dealing with the losses from the war, reconfiguring what it meant to be a man. This reconfiguration of gender took place in a context of change in Germany. Many women entered the workforce to replace the lost men. The economic downturn and reliance on funding from the United States motivated many within Germany to examine gender roles and to reassemble masculinity to meet changing circumstances.

Protecting A Woman’S Right To Abortion During A Public Health Crisis, San Juanita Gonzalez

The Scholar: St. Mary's Law Review on Race and Social Justice

As COVID-19 infected our nation, states were quick to issue executive orders restricting various aspects of daily life under the pretense of public safety. It was clear at the outset that certain civil liberties were going to be tested. Among them, the constitutional right to an abortion.

This comment explores Texas’ response to the COVID-19 pandemic and the limitations it imposed on abortion access. It will attempt to address the legitimacy of the “public health concerns” listed in executive orders issued throughout numerous states and will discuss the pertinent legal framework and judicial scrutiny to apply.

Antiviral Polymers: A Review, Ali Akbari, Ashkan Bigham, Vahid Rahimkhoei, Sina Sharifi, Esmaiel Jabbari

Faculty Publications

Polymers, due to their high molecular weight, tunable architecture, functionality, and buffering effect for endosomal escape, possess unique properties as a carrier or prophylactic agent in preventing pandemic outbreak of new viruses. Polymers are used as a carrier to reduce the minimum required dose, bioavailability, and therapeutic effectiveness of antiviral agents. Polymers are also used as multifunctional nanomaterials to, directly or indirectly, inhibit viral infections. Multifunctional polymers can interact directly with envelope glycoproteins on the viral surface to block fusion and entry of the virus in the host cell. Polymers can indirectly mobilize the immune system by activating macrophages and …

Safety And Efficacy Of Systemic Anti-Scg3 Therapy To Treat Oxygen-Induced Retinopathy, Chang Dai, Hong Tian, Amit Bhatt, Guanfang Su, Keith A Webster, Wei Li

Faculty, Staff and Students Publications

BACKGROUND: To circumvent possible systemic side effects, anti-angiogenic drugs targeting vascular endothelial growth factor (VEGF) for ocular neovascular diseases in adults are approved only for intravitreal administration. However, intravitreal injection itself can elicit injection-related adverse effects, and premature eyes of infants with retinopathy of prematurity (ROP) may be particularly susceptible to intravitreal injection. Therefore, an unmet clinical need is to develop safe systemic anti-angiogenic therapies for ROP. We recently reported that secretogranin III (Scg3) is a disease-restricted angiogenic factor and that systemic anti-Scg3 mAb alleviates ROP in animal models with minimal side effects on developing eyes and organs. The aim …

Hyperactivation Is Sufficient To Release Porcine Sperm From Immobilized Oviduct Glycans, Momal Sharif, Vincent Hickl, Gabriel Juarez, Xingjian Di, Karl Kerns, Peter Sutovsky, Nicolai Bovin, David J Miller

Faculty, Staff and Students Publications

Fertilizing sperm are retained by adhesion to specific glycans on the epithelium of the oviduct forming a reservoir before sperm are released from the reservoir so fertilization can ensue. Capacitated sperm lose affinity for the oviduct epithelium but the components of capacitation that are important for sperm release are uncertain. One important correlate of capacitation is the development of hyperactivated motility. Hyperactivation is characterized by asymmetrical flagellar beating with high beat amplitude. We tested whether the development of full-type asymmetrical motility was sufficient to release sperm from immobilized oviduct glycans. Sperm hyperactivation was induced by four different compounds, a cell-permeable …

The Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report a high-resolution record of dust deposition and ocean productivity for the Antarctic Zone, close to the main dust source, Patagonia. Our deep-ocean records cover the last 1.5 Ma, thus doubling that from Antarctic ice-cores. We find a 5 to 15-fold increase in dust deposition during glacials and a 2 to 5-fold increase in biogenic silica deposition, reflecting higher ocean productivity during interglacials. This antiphasing persisted throughout the last 25 glacial cycles. Dust …

The Ethics Of Care And The U.S. Covid-19 Pandemic Response, Samantha Treveline Barrett

Departmental Honors & Graduate Capstone Projects

Throughout the pandemic, many conservatives like President Donald Trump lacked emotional sensitivity in regards to the millions of lives affected by COVID-19. They believed themselves to be too strong for the virus to take them down, and viewed those who wore masks as weak and afraid. Unlike Democrats, Republican governors entrusted their constituents to take necessary safety precautions and avoided statewide mask mandates, vaccine requirements, and lockdowns. Their policies and rhetoric demonstrated the overlap in harmful masculine traits and the conservative values of self-sufficiency and independence. Using a case study method, this paper analyzes the role of gender in a …
