The importance of equipping staff with suicide screening knowledge is to help decrease suicide attempts, suicide thoughts, and completed suicide in patients. The practice-focused question for this staff education project asked if staff education for nursing staff and psychiatrists would increase their knowledge about suicide prevention methods and suicide screening techniques. The purpose of the …

Investigating The Relationship Between The Microbiome And Neuroactive Metabolites In Huntington Disease Model Mice, Christian Millot

Electronic Theses and Dissertations, 2020-2023

Huntington Disease (HD) is an autosomal dominant neurodegenerative disorder caused by a trinucleotide repeat expansion mutation in the huntingtin (HTT) gene. HD is characterized by neurological symptoms, including motor, cognitive, and psychiatric decline. A non-neurological symptom, metabolic dysfunction, is also common in HD and can cause weight change, a feature recapitulated in HD mice. There is a need for a better understanding of the weight changes associated with HD, because patients with a higher body mass index show slower disease progression. Our lab has shown that metabolic dysfunction in HD mice is the result of a disrupted circadian feeding rhythm …

Investigation Of Realism In Facial Characteristics And Anthropomorphic Language In The Design Of Multimedia Instruction, Ecem Olcum

Electronic Theses and Dissertations, 2020-2023

Emotional design elements have recently been added to the research in cognitive load and multimedia learning (Um et al., 2012). One aspect of eliciting positive emotions is to use anthropomorphic design, which has been found to increase learning performance (Um et al., 2012; Plass et al., 2014; Park et al., 2015; Schneider et al., 2018). The current research aimed to investigate three design factors in three studies: anthropomorphism in verbal and visual design, single-frame or multi-frame illustrations, and realism of the anthropomorphic visual design. The first study confirmed that the anthropomorphic verbal and visual materials were perceived as anthropomorphic by …

Role Of Biological Clocks In Ant Behavioral Plasticity And Parasitic Manipulation Of Ant Behavior, Biplabendu Das

Electronic Theses and Dissertations, 2020-2023

Living organisms exhibit daily rhythms as a way to anticipate predictable fluctuations in their environment. Such daily rhythmicity is the phenotypic outcome of oscillating genes and proteins, driven by an endogenous biological clock. Clock-controlled behavioral rhythms are inherently "flexible" since their phase, amplitude, and period can change throughout an animal's life hallmarked by changes in so-called chronotype. How this inherent plasticity of clock-controlled rhythms is linked to plasticity of behavior is still an open question in biology. Characterizing the various mechanistic links between plasticity of the animal clock and behavioral state will not only shed light on the molecular underpinnings …

An Examination Of Gender-Based Differences In Perceptions Of Supervisor Support, Ann Schlotzhauer

Electronic Theses and Dissertations, 2020-2023

Perceived supervisor support and particularly emotional support possess conceptual overlap with stereotypes of femininity. The present study extends understanding of perceived supervisor support by applying the agency and communality framework of gender stereotypes and role congruity theory. This study employed a vignette research design to examine differential ratings of male and female supervisors who were depicted engaging in (a) no support, (b) instrumental support, (c) emotional support, or (d) instrumental and emotional support. Results suggest that supportive supervision is indeed viewed as feminine in nature. Further, findings suggest that female supervisors engaging in emotional support behaviors are preferred over equivalently …

Assessment Of Sexual And Protective Behavioral Strategies: Development Of The Sexual And Negative Dating Inventory, Roselyn Peterson

Electronic Theses and Dissertations, 2020-2023

Adverse sexual outcomes (ASOs) including sexual violence, risky sex, and sexual regret are highly prevalent among college students, with 20-25% of female undergraduates experiencing sexual assault, at least 60% of undergraduates engaging in risky sex, and lifetime rate of regretted sexual experiences as high as 72%. ASOs are associated with increased psychological problems, increased alcohol use, and decreased protective behavioral strategies (PBS). The most recent measure of dating and sexual PBS was published over a decade ago. The current study is the development and validation of an updated measure of dating and sexual PBS; the Sexual and Negative Dating Inventory …

Juvenile Dispersal And Genetic Connectivity In The Sea Turtle 'Lost Years', Katrina Phillips

Electronic Theses and Dissertations, 2020-2023

Juvenile dispersal is a life history strategy found across taxa and habitat types. In this dissertation, I examine juvenile dispersal in an evolutionary context and explore the conditions that support high dispersal, which necessitates subsequent ontogenetic habitat shifts. I use a sea turtle study system to evaluate the genetic and behavioral patterns associated with juvenile dispersal and ontogenetic shifts in marine environments. Specifically, I focus on four sea turtle species found in the northeastern Gulf of Mexico in the early life stage known as the 'lost years': green turtles (Chelonia mydas), Kemp's ridleys (Lepidochelys kempii), loggerheads (Caretta caretta), and hawksbills …

Non-Invasive Detection Of Elevated Intracranial Pressure Using Spontaneous Tympanic Membrane Pulsation, Rajkumar Dhar

Electronic Theses and Dissertations, 2020-2023

Monitoring intracranial pressure (ICP) is a standard diagnostic tool for various neurological conditions such as head injury, ruptured aneurysms, intracerebral and intracranial hemorrhage, and hydrocephalus. Currently, ICP monitoring relies on invasive pressure measurements. These include intraventricular catheter, subdural screw, epidural sensor, and lumbar puncture. Invasive methods pose the risk of infection and hemorrhage, are expensive, and require special clinical skills. A noninvasive method that is reliable, simple to use, low-cost, and provides easily interpretable results can help avoid the complications associated with the invasive methods. This study proposes a novel method for noninvasive ICP monitoring using tympanic membrane pulsation (TMp). …

A Measurement System For Detection Of Intestinal Motility In Neonates By Monitoring Slow Wave Activity, Garett Goodale

Electronic Theses and Dissertations, 2020-2023

Similar to how electrocardiographic waves are the pace making signals of the heart, slow waves are the pace making signals of the intestines. Slow waves are electrical signals in the intestines that determine the speed at which food can move through the intestine ensuring proper digestion and uptake of nutrients. It has been shown that slow waves can be measured in adults using non-invasive, surface electrodes. However, no study has investigated the measurements of slow waves in neonates, specifically pre-term neonates. Around 7% of pre-term neonates suffer from necrotizing enterocolitis (NEC) which is a condition that causes damage to the …

Trauma And Resilience Among Migrant Children From Mexico And The Northern Triangle En Route To The United States, Georgina Sanchez Garcia, Mark Lusk, Paula Chavez Santamaria

The Journal of Sociology & Social Welfare

Children who are forced to migrate to flee violence, extreme poverty, and natural disasters are exposed to trauma in their countries of origin and on the migrant trail. Forced child migrants from Central America and Mexico who flee to the U.S. border are particularly vulnerable. In this qualitative study, we interviewed 76 migrant children from Mexico, El Salvador, Honduras and Guatemala. We listened to their stories and assessed exposure to adverse events, traumatic stress and child resiliency. While children experienced adversity and trauma, they were protected by high levels of resiliency that is grounded in family, faith, courage and camaraderie.

Elucidating The Role Of Polycomb Repressive Complex 2 In Lung Stem Cell Fate And Lung Disease, Aria Byrd

Theses and Dissertations--Toxicology and Cancer Biology

The average human lungs take ~22,000 breaths and inhale ~2,000 gallons of air each day. This organ is the primary conduit for the transfer of oxygen to the internal organs, making it crucial for the sustainment of life. Consequently, mechanical malfunction of the lungs and/or pollution of inhaled air negatively impact internal organ function and ultimately put survival in jeopardy. Epigenetics, by nature, is a plastic phenomenon in which environmental stimuli influence short term, long term, and generational gene expression patterns. Chronic exposure of harmful stimuli to the lung epithelium has also been shown to alter epigenetic pathways, engender aberrant …

Extracellular Vesicles And Cancer Therapy: An Insight Into The Role Of Oxidative Stress, Jenni Ho

Theses and Dissertations--Toxicology and Cancer Biology

As a result of improvements in cancer detection and treatment methods, a growing population of cancer survivors are living with side effects associated with their cancer therapy. Oxidative stress plays a significant role in the development of cancer and as a mechanism for cancer therapy to exert its therapeutic effects, resulting in off-target tissue damage. Radiation has been long established as a means to utilize the generation of reactive oxygen species to kill cancer cells, and 50% of chemotherapy agents currently used are associated with inducing oxidative stress. One major side effect observed in cancer survivors is a decline in …

Overcoming Resistance To Sg-Aris In Castration-Resistant Prostate Cancer, Chaohao Li

Theses and Dissertations--Toxicology and Cancer Biology

Prostate cancer (PCa) ranks as the most diagnosed type of cancer and the second leading cause of death in men. Androgen receptor (AR) signaling plays a pivotal function in promoting the survival and progression of PCa. Therefore, medication for PCa mainly focuses on the inhibition of AR pathway, which is termed androgen deprivation therapy (ADT). However, the disease eventually progresses and develops to a lethal stage called castration-resistant prostate cancer (CRPC) that is characterized by resistance to canonical ADT. To deal with this situation, several second-generation AR inhibitors (SG-ARIs) have been created that have better efficacy against AR, including Enzalutamide …

Stay-At-Home Fathers: What Is Their Life Really Like? An Intimate Portrayal, Christi Ann Hosking

Graduate Theses/Dissertations

Reinforced by years of gender stereotypes is modern societies’ definition of masculinity, which has long been characterized by breadwinning and providing. Current literature has observed the growing trend which finds an increasing number of men engaged in the role of caregiver and the dynamic change in the home-work balance. Only a few studies looked at what life is like for a stay-at-home father and even fewer have allowed these fathers a unique voice for sharing their story. The purpose of this study was to gain an in-depth understanding of what day to day life was really like as a stay-at-home …

The Role Of The Host Factor Sptbn1 In Hiv-1 Infection Of Microglial Cells, Marc Gordon Havlicek

Graduate Theses/Dissertations

HIV-1 is the etiological agent that cause AIDS. Since the 1980’s when HIV-1 was discovered, much has been discovered, however a cure for HIV-1 has eluded researchers. Effective therapeutics do exist but can have adverse side effects including HAND/HAD which leads to neurodegeneration in patients regardless of viral suppression. One area of research that holds the possibility of discovering new viral targets and therapeutics is host factor interaction within the replication process. One host factor that can cause a decrease in HIV-1 infectivity is SPTBN1. SPTBN1 is a cytoskeletal protein that was shown to bind to the capsid and nucleocapsid …

Overcoming The Odds: The Effects Of The Relationship Between Childhood Adversity, Lifetime Trauma, And Resiliency On Empathy And Conscientiousness, Victoria West Staples

Graduate Theses/Dissertations

This research sought to understand the connection between trauma and the development of resiliency while examining the effects of that relationship on empathy and conscientiousness. Specifically, this study was created to answer four main questions: (1) Does early childhood adversity predict later life trauma? (2) Does childhood adversity and cumulative lifetime traumatic experiences impact the development of resiliency and its subconstructs (i.e., interpersonal resiliency and intrapersonal resiliency)? (3) Is empathy impacted by the presence of resiliency, specifically examining its effect on cognitive and affective empathy (using questionnaires and galvanic skin response)? (4) And is conscientiousness related to resiliency subconstructs? There …

Tissue And Sex-Specific Rna Editing During Induced Acute Inflammation, Claire E. Nichols

Graduate Theses/Dissertations

A-to-I RNA editing is a process where select adenosine (A) nucleotides are deaminated by an editing enzyme, ADAR, to become inosines (I) in RNA transcripts. RNA editing can affect the sequence of the encoded protein and the regulation of the RNA. ADAR1 also plays a role in regulating innate immunity and its expression is upregulated during inflammation. Current data on the effects of increasing ADAR1 on RNA editing is limited, and most studies are completed only in male animals. We are interested in expanding RNA editing data to include female animals. Lipopolysaccharide (LPS) was used to induce acute inflammation and …

Characterization Of Nanoparticles Using Inductively-Coupled Plasma Mass Spectrometry, Jabez D. Campbell

Single Particle Inductively Coupled Plasma Mass Spectrometry (SP-ICP-MS) is a functional method that could fill the characterization need in the nanomaterial research field. Using data from both SP-ICP-MS tests and data from literature established characterization methods, the viability of making SP-ICP-MS the standard …

Elucidating The Role Of Hemodynamic Force In Regulating The Attachment Of Vascular Smooth Muscle Cells (Vsmcs) To Maturing Vessels During Mouse Embryonic Development, Israt Jahan

Graduate Theses/Dissertations

Blood vessel maturation is characterized by the recruitment and attachment of vascular smooth muscle cells (vSMCs) around immature blood vessels, which ultimately form the tunica media. Improper maturation can lead to vascular birth defects ranging from minor birthmarks to lethal brain aneurysms. Previously, our lab demonstrated that hemodynamic force plays an important role to regulate vSMCs recruitment from neighboring low-flow to high-flow vessels followed by the attachment of these vSMCs to the high-flow vessels. To understand the reason for the preferred attachment of vSMCs to high-flow vessels, instead of low-flow vessels, I hypothesize that hemodynamic force modulates the expression of …

Utilizing Virtual Reality Goggles During Pediatric Laceration Repairs To Reduce Perceived Pain In Pediatric Patients, Emily C. Bozzer

Graduate Theses/Dissertations

In pediatric emergency departments, several providers assess pediatric patients in need a laceration repair, require procedural sedation in order to ensure compliance and complete the laceration repair. This study explored one safe alternative to procedural sedation during pediatric laceration repairs by assessing what pain scores pediatric patients report when undergoing a laceration repair utilizing virtual reality goggles. Pediatric patients ages 6-17 years old perceived pain scores utilizing FACES pain scale was documented. This study found a majority of patients reported lower pain scores during the laceration repair in comparison to their baseline pain score.

Identification Of A Novel Protein Interaction That Elucidates The Mechanism Of Idiopathic Recurrent Miscarriages In Women With Nlrp2 Mutations, Nayeon Son

Graduate Theses/Dissertations

The protein NOD-Like receptor pyrin domain containing 2 (NLRP2) is one member of a larger family of protein receptors that plays an important role in our innate immune system. In humans, the NLR family consists of 22 proteins. However, only about a half of NLRs’ functions are known, but many are pro-inflammatory, causing inflammation. NLRP2 has been identified to be a maternal effect gene regulating early embryo development in idiopathic recurrent miscarriages. In previous studies, mutations in the NLRP2 gene resulted in genetic maternal imprinting disorders due to NLRP2 regulating DNA methylation. However, the exact mechanisms involved in recurrent miscarriages …
