Over Sexualization Of Women In The Media And Its Effect On Self-Objectification, Alaysia M. Herndon

Honors Undergraduate Theses

The current study examined the relationship between the sexualization of women in the media and its effects on women's self-objectification and sexual priming with sociodemographic variables as a mediator. It was hypothesized that (1) exposure to increased sexual content in music videos would positively correlate with increased sexual priming among viewers and (2) increased sexual priming among females would be associated with increased self-objectification and increased objectification of other women. Additionally, the current study aimed to examine sociodemographic factors and if they correlate to the impact of sexual priming on self-objectification and the objectification of other women. The results of …

Development Of A Sox9 Reporter Cell For High-Throughput Chondrogenic Assessment, Alyssa R. Mickle

Honors Undergraduate Theses

Osteoarthritis (OA) is a debilitating disease caused by the deterioration of articular cartilage and is a leading cause of disability in the United States and worldwide. Much current research into improved treatment for this disease is focused on tissue engineering through the growth of cartilage sheets made by articular chondrocytes. However, as chondrocytes proliferate in vitro, they also lose their ability to produce dense extracellular matrix, a necessary component of articular cartilage conferring mechanical strength. SOX9, a transcriptional activator, increases type II collagen expression, a key articular cartilage extracellular matrix component. Thus, SOX9 promotes an articular cartilage phenotype. Therefore, …

Synthesis Of Polyacrylic Acid - Dopamine Nanoparticles As Radical Scavengers For Antioxidant Applications, Russell D. Cox

Honors Undergraduate Theses

The antioxidant activity of novel drugs has been of increasing interest in recent years. Free radicals are linked as a cause to many diseases such as atherosclerosis and cancer,1 so development of drugs that can scavenge and break down free radicals is needed. One such potential solution is using dopamine, which is water-soluble and an antioxidant. However, the tendency of antioxidant drugs reacting undesirably with proteins and other biochemical compounds is a big issue for the drugs' antioxidant potential. One solution is by encapsulating the antioxidant compound in biocompatible polymer nanoparticles. In this project, dopamine is bound to the polymer …

Sensing Symbiosis: Investigating The Symbiotic Magnetic Sensing Hypothesis In Fish Using Genomics, Elizabeth Boggs

Honors Undergraduate Theses

The mechanism behind magnetoreception – the ability to sense magnetic fields for orientation and navigation – still remains one of the most difficult questions to answer in sensory biology, with fish being just one of many taxa known to possess this sense. Characterizing a magnetic sense in fish is crucial for understanding how they navigate their environment and can inform on how increasing anthropogenic sources of electromagnetic fields in aquatic environments may affect threatened fish species. This study examined the hypothesis put forth by Natan and Vortman (2017) that magnetotactic bacteria (MTB), bacteria that create their own chains of magnetic …

Role Of Polyploidy In Leaf Functional Trait Evolution Across Wild Helianthus, Anestacia S. Robinson

Honors Undergraduate Theses

Whole genome duplication, or polyploidy, is a common process in plants by which failures in meiosis or fertilization result in offspring with twice the number of chromosomes. This doubles the number of copies of every gene, an effect thought to generate new ‘raw material' upon which natural selection can act. Few studies exist examining the consequences of polyploidy for plant physiological traits. Doubling the number of gene copies may have unknown effects on leaf structure and function. In this study, I compare diploid, tetraploid, and hexaploid species within the genus Helianthus (wild sunflowers). Forty different accessions of wild sunflowers were …

"The Milk Is Love": Understanding Mothers' Emotional Attachment To Breastmilk, Chandel M. Perez

Honors Undergraduate Theses

Mothers are known to have an emotional attachment to their infant; however, some mothers also experience an emotional attachment to their own milk. Exclusive breastfeeding in the first six months of life, followed by continued breastfeeding with complementary solids are recommended by the American Academy of Pediatrics and the World Health Organization. Some mothers produce enough surplus milk to donate to a human milk bank. This thesis considers the emotional attachment to milk experienced by women who donate milk to a milk bank. This research is based on participant observation in a human milk bank in Florida and interviews collected …

Social Stigma, Public Health, And Addiction In Albania, Ediola Malkouari

Honors Undergraduate Theses

Drug use is considered in many countries the plague of today's society. Researchers from medical, psychological and sociological fields, as well as lawmakers, are interested in finding more answers to this widespread phenomenon. All over the world there are known conflicts related to drug producing, transportation routes and distribution, that harm the economy and social standing of the involved communities or countries. Policies towards drug use vary from country to country, but this research focuses on how stigma affects the lives of individuals suffering from substance use disorder (SUD) in Albania. Substance use disorder is not often considered a disease, …

Understanding Aggressive Driving Behavior: The Role Of Personality And Individual Differences, Enilda M. Velazquez

Honors Undergraduate Theses

According to recent reports, 56 percent of total vehicular accident deaths were related to aggressive driving. Previous research on aggressive driving was related to cognitive failures, sex differences, individual driving habits, and to a lesser extent, personality. Personality focused aggressive driving research has not produced a consensus on the predictive nature of personality traits on the propensity to engage in aggressive driving. However, a lack of consensus on personality's role in aggressive driving warrants further empirical examination into the relationship between personality and aggressive driving. Similarly, the impact of individual differences on aggressive driving behavior cannot be ignored; the role …

Effects Of Death Anxiety On Learning Performance, Umaima Haseeb

Honors Undergraduate Theses

The present study examines whether or not a person's anxiety level might be linked to their learning performance. Many studies in the past have examined math and test anxiety, but the present study will examine the effects of death anxiety on learning performance. Individual's anxiety will attempt to be induced through fear of death. Participants were presented a set of four symptoms, similar to Gluck and Bower's 1988 category learning study. The participants were asked whether or not they think the symptoms of the patient are positive for COVID-19 or positive for the flu. The hypothesis was that there would …

Detection Of Point Mutations Conferring Gentamicin Resistance In Escherichia Coli Using A Split-G4 Probe, Michael J. Greenberg

Honors Undergraduate Theses

The objective of this project was to develop a DNA hybridization sensor that can detect the presence of E. coli and reveal its resistance to the drug gentamicin. This probe will enable rapid and user-friendly diagnostics of E. coli infections and analysis of bacterial gentamicin-susceptibility profile by interrogation of a fragment of E. coli 16S rRNA bearing a substitution in the gentamicin-resistant cells. The sensor is promising for the point-of-care use to provide a timely UTI diagnostic solution. A quick diagnosis of E. coli infection and antibiotic resistance is crucial for treatment. To design a hybridization probe, we proposed a …

Nanopore-Based Metagenomic Comparison Of Airway Colonizers Between Cystic Fibrosis Patients And Healthy Individuals, Anita Samadabadi

Honors Undergraduate Theses

Cystic fibrosis (CF) is an autosomal recessive genetic disorder involving a mutation in the CF transmembrane conductance regulator protein (CFTR), which causes dysfunctional transport of chloride ions across cell membranes. CF affects multiple body systems and a few of its symptoms include chronic cough, difficulty breathing, obstructive airway disease, bacterial pulmonary infections, maldigestion, malabsorption, pancreatitis, and male infertility. Until recently, treatment options have been limited to alleviating symptoms, but a new classification of drugs, CFTR modulators, provide an opportunity to slow the progression of the disease and improve clinical outcomes. The effect of CFTR modulators may be attributed to the …

Systematic Literature Review Of Cognitive Behavioral Treatments For Patients With Classical, Secondary, And Idiopathic Trigeminal Neuralgia, Linnea B. Herzog

Honors Undergraduate Theses

Trigeminal neuralgia is a painful neuralgia with a complicated pathology that is not clearly understood. Due to the ambiguity of the condition, patients often have to search for medical providers that specialize in trigeminal neuralgia, and even with the guidance of a specialist, some patients do not respond well to treatment.¹ Despite the uncertainty surrounding the specifics of the disease, there are treatments available that can provide some level of pain relief for patients suffering from this disorder. When a patient does not respond well to medical therapy, surgery can be the next appropriate step in patient care management. …

Managing Invasive Plants On Great Plains Grasslands: A Discussion Of Current Challenges, John Gaskin, Erin Espeland, Casey D. Johnson, Jane M. Mangold, Rachel A. Mcgee, Chuck Milner, Shishir Paudel, Dean E. Pearson, Lora B. Perkins, Chadley W. Prosser, Justin B. Runyon, Sharlene E. Sing, Zachary A. Sylvain, Amy J. Symstad, Daniel R. Tekiela

Native Plant Focused Publications

The Great Plains of North America encompass approximately 1,300,000 km² of land from Texas to Saskatchewan. The integrity of these lands is under continual assault by long-established and newly-arrived invasive plant species, which can threaten native species and diminish land values and ecological goods and services by degrading desired grassland resources. The Great Plains are a mixture of privately and publicly owned lands, which leads to a patchwork of varying management goals and strategies for controlling invasive plants. Continually updated knowledge is required for efficient and effective management of threats posed by changing environments and invasive plants. Here we …

Fabrication Of Photoresponsive Crystalline Artificial Muscles Based On Pegylated Covalent Organic Framework Membranes, Xiuxiu Guo, Tianhui Mao, Zhifang Wang, Peng Cheng, Yao Chen, Shengqian Ma, Zhenjie Zhang

Chemistry Faculty Publications

Seeking new photoresponsive materials with high energy conversion efficiency, good mechanical properties, as well as well-defined photoactuation mechanisms is of paramount significance. To address these challenges, we first introduced crystalline covalent organic frameworks (COFs) into the photoactuator field and created a facile fabrication strategy to directly install photoresponsive functional groups (i.e., acylhydrazone) on the skeletons of COFs. Herein, an approach to use polyethylene glycol (PEG) cross-linked dimers as the building blocks of the COF-42 platform was developed and afforded a series of uniform and freestanding membranes (PEG-COF-42) with outstanding mechanical properties (e.g., high flexibility and mechanical strength). Notably, these membranes …

Portrait Of A Novice Medical Family Therapist, Working In A Medical Setting With Head And Neck Cancer Patients Observed Through A Bowen Family Systems Theory’S Lens, Venetia Bennett

Department of Family Therapy Dissertations and Applied Clinical Projects

Each year, approximately 43,000 people in the United States, receive a diagnosis of cancer of the head and neck (American Cancer Society 2019). A diagnosis of cancer, regardless of its location can be overwhelming for patients, their caregivers, and their family system. Receiving such a diagnosis causes a reaction of heightened emotions and anxiety. With that, there is a growing need for medical familytherapists. Medical family therapy has been documented as an effective approach for aiding medical providers to increase the quality of care for patients. Traditionally, medical family therapy is associated withgeneral practitioners, pediatricians, and such medical environments. This …

Awareness Of The Use Of Self In Therapy: An Autoethnographic Inquiry Into The Training Experiences Of A Black, Single, Female Mft Doctoral Student, Phyllis Days

Department of Family Therapy Dissertations and Applied Clinical Projects

The "self" of the therapist is an essential factor in the therapeutic process (Baldwin, 2000) and is impacted by intersections of identities and prejudicial treatment, which creates unjust conditions for Black women in society and academia. Nonmembers of the predominant culture can find difficulties in navigating the "self" of the therapist, which reflects personal and social experiences. In academia, the Black woman's identity continues to face problems of exclusion and oppressive related situations, which can complicate the learning process (Ong, Wright, Espinosa, & Orfield, 2011). Several studies have explored the challenges ofAfrican-American students and faculty, in MFT graduate programs, who …

Frequency And Perceived Authenticity Of Social Determinants Of Health Discussion By Medical Trainees, Priyadarshini Chandrashekhar, Emily J. Noonan, Laura A. Weingartner

Undergraduate Arts and Research Showcase

Introduction

Social determinants of health (SDOH)—the conditions in which people live, learn, and work—play a vital, but often neglected role in shaping a community’s health. SDOH influence risk factors for disease and access to healthcare, consequently promoting health inequities among different populations. Examining how providers discuss SDOH with patients can identify opportunities to better integrate social context into care.

Methods

We analyzed standardized patient (SP) encounters of rising UofL M3 trainees to 1) determine whether SDOH are integrated into healthcare conversations, and 2) investigate what constitutes an authentic conversation to identify how trainees can better express interest in a patient. …

That's Irrelephant: Children's Judgments Of Relevant And Irrelevant Animal Observations, Rebekah C Cook, Alexandra Ducloux, Allison Williams, Judith Danovitch

Undergraduate Arts and Research Showcase

Abstract:

The ability to make judgments about different kinds of evidence is an important skill for learning about science. This study investigated if children recognize how helpful relevant and irrelevant information is for evaluating biological explanations, and whether their judgments change with age. Participants were 24 7- and 8-year-olds and 26 9- and 10-year-olds. Children heard a statement about an animal's behavior. Then children heard an explanation for that behavior followed by 2 different observations. One observation was about the same animal but was irrelevant to the explanation. The other observation was about a different animal, but was relevant to …

Biofilm Associated Staphylococcus Aureus Viability Is Altered By Burkholderia Cenocepacia, Bridget Wall, Tiffany J. Brandt, Dr. Deborah Yoder-Himes

Undergraduate Arts and Research Showcase

Respiratory failure caused by chronic and recurrent microbial infections is the most common cause of death for people with cystic fibrosis (CF)¹, a disease causing the formation of thick mucus in the lungs². Most bacteria can form biofilms, collections of sessile cells adhered to a surface by a secreted substance. Biofilm-associated cells develop antibiotic resistance at higher rates³. The thicker mucus in CF lungs is extremely difficult to clear via action of the mucociliary escalator and its presence fosters the formation of bacterial biofilms. Staphylococcus aureus and Burkholderia cenocepacia are two pathogens commonly found …

Screening For E-Cigarette And Tobacco Use In Standardized Patient Encounters, Michael A. Schmidt, Emily J. Noonan, Laura A. Weingartner

Undergraduate Arts and Research Showcase

E-cigarette usage has grown significantly in recent years, with over 5 million US middle and high school students reporting recent usage. The long-term health consequences of these devices are still being investigated, but it is known that e-cigarette aerosol could contain harmful substances including nicotine, heavy metals, and carcinogens. Therefore, it is important for physicians to ask patients about e-cigarette usage specifically, as this may contribute to future health problems. The goal of this study was to investigate if and how medical students screen for e-cigarette usage. Screening language was reviewed in standardized patient encounters, which are a type of …

Belief In Genetic Determinism Within Academic Levels, Miranda Massmann, Katie Humrick, Linda Fuselier

Undergraduate Arts and Research Showcase

Belief in genetic determinism (BGD) is the belief that genes attribute more influence on the expression of traits than scientific research supports. The environment and other factors, such as epigenetics, factor heavily into the expression of traits and it is important that students from all backgrounds understand this since BGD has been associated with societal instances of racism and sexism. We analyzed essay responses that undergraduate students wrote in response to a socioscientific issue (SSI) about the use of CRISPR/Cas9 technology for non-medical enhancement in humans to examine the presence of BGD. Our sample was composed of non-biology majors, lower …

Crawl Space: Driving Over The Anthropocene In A Jeep, Michael Pesses

CGU Theses & Dissertations

The automobile has long been directly and indirectly connected to human conceptions of nature, yet few studies linger with the act of driving as a practice that contributes to how nature is experienced. I argue that a more nuanced understanding of automobility is necessary for any scholars who study both social practices and environmental sustainability. Following the work of the human geographer Doreen Massey, I explore how relations between humans and non-humans, the social and the natural, ideology and practice work together to produce places specific to space and time. I also argue that American automobility is not simply transportation, …

The Impact Of A University/Online Program Management Provider Partnership On Faculty Approaches To Teaching Design: A Case Study Using Activity Theory, Swati Ramani

CGU Theses & Dissertations

As the number of online courses increase in Higher Education, many higher education institutions outsource online course development to an Online Program Management (OPM) provider because of a lack of budget, staff, and technology. Current research indicates that OPMs often do not have instructional design (ID) services tailored to a specific university. This research uses a Case Study in order to analyze how the nature and dynamics of a business partnership between a research university and an OPM provider impact faculty engagement and development of pedagogical and technological knowledge. They Activity Theory conceptual framework was used to direct inquiry and …

The Role Of Female Headed Households Caring For Children And No Spouse In Gentrification In Los Angeles, Jovita Murillo

CGU Theses & Dissertations

Gentrification is the “in-migration of a relatively well-off, middle- and upper-middle-class population” into historically marginalized communities (Centers for Disease Control and Prevention (CDC); Matsuoka et al. 2017). Literature has repeatedly shown that gentrification is placing cost and rent-burdened residents at risk of displacement due to the hike in housing prices and rents. Most cost and rent burdened households are female-headed households caring for children without a spouse (FHHCCNS) (Colburn and Allen, 2018). Given there is a lack of literature describing the role of gender in gentrification, this descriptive study aims to describe the gentrification profile in Los Angeles using multiple …

A Web Of Connections: How Early Twentieth-Century American Women Writers And Photographers Situated A New Way Of Seeing, Kristina Krause

CGU Theses & Dissertations

While there are several studies of the relationships and influences between American male photographers and writers, this study examines the lesser known and understudied collaborations and connections between early, twentieth-century American women photographers and writers, beginning around the end of the nineteenth century and extending into the 1930s. The web of connections between women writers and photographers, connections created through influence, through mentorship, through friendship, or through collaboration, provided a space in which they could situate a new way of seeing and defining each other as women and as artists, and it manifested in the empathetic manner in which they …

Recidivism Among Previously Incarcerated People Enrolled In Riverside County Whole Person Care, Ndifreke Emmanuel Etim

CGU Theses & Dissertations

The United States continues to policy shift towards reducing the number of incarcerated people; however, many people released from incarceration will be rearrested due to re-entry challenges. Several re-entry programs, such as the Whole Person Care pilot, have been developed to address these challenges and ensure that formerly incarcerated people successfully transition into the community. The primary aim of this project is to explore the determinants of recidivism among previously incarcerated people enrolled in the Whole Person Care pilot in Riverside County. This study suggests early linkage to services, such as mental health and substance use treatment services, will reduce …

Challenges Faced By Bisexual And Gay Black Men On College Campuses, Sammie Lee Scales Jr

CGU Theses & Dissertations

Many previous studies have focused on the aggressive homophobic discrimination and harassment that LGBTQ students face on college campuses, as well as measures taken to improve their situation. However, few studies have explored the unique forms of sexual and racial discrimination encountered by Black male gay and bisexual college students (BMGBCS). Using intersectionality and queer theory as guiding philosophies, this study looks at how BMGBCS—being Black, male, and nonheterosexual—are subject to oppression at multiple levels of identity and in ways that are unique as regards the overall LGBTQ community. To accomplish this goal the study employed a qualitative phenomenological approach …

Machine Learning Methods For The Analysis Of Metagenomes, Vito Adrian Cantu Alessio Robles

CGU Theses & Dissertations

As of October 2020, there are 18.6 × 1015 DNA base pairs publicly available in the Sequence Read Archive and this number is growing at an exponential rate. As DNA sequencing prices continue to drop, many research groups around the world have incorporated high throughput sequencing in their research, giving us access to sequences from many distinct ecosystems. This has revolutionized the field of metagenomics, which aims to fully characterize all organisms and their interactions in a particular system. Nevertheless, the plethora of available data has made its analysis difficult as traditional techniques such as genome assembly or sequence alignment …

The Emergence Of Modernity In The Early Aerospace Industry 1950-1970, Lachlan Warwick Sands

CGU Theses & Dissertations

The literature regarding the management of science during the early aerospace industry between 1950 and 1970, and more specifically the period of Lockheed’s transition from aeronautics into aerospace, is sparse and the subject is insufficiently studied. In this dissertation I examine how the practice of science changed in the United States in the decades after World War II. The scientific endeavor in the United States manifested a transformation from an enlightenment-based set of norms to a new modern ethos. For all intents and purposes, the traditional intellectual boundaries between basic science, applied science, and technology dissolved across the majority of …
