Essays On Managerial Opportunism, Pension De-Risking, And Corporate Investment Policies, Brian Silverstein

Electronic Theses and Dissertations 2020 - Present

In the first essay, I examine how managerial opportunism affects corporate investment efficiency and, ultimately, firm performance. Prior research establishes corporate investment efficiency as a function of the firm’s information environment and internal governance. To measure managerial opportunism, I use an ex-ante firm level measure of managerial opportunism based on insider trading patterns and test its effects on investment efficiency and performance. Extant research associates opportunistic insider trading with opaque information environments about the firm and weak firm governance, making it an apropos proxy for opportunistic managerial behavior. Despite the clear establishment of opportunistic insider trading as an agency problem …

Food Web Modeling To Assess Interactions Between Artificial Reefs And Natural Reefs, Elizabeth A. Mcnamee

Electronic Theses and Dissertations 2020 - Present

The effect of artificial reefs on natural reefs is poorly understood. This study focused on Aquarius Reef Base (ARB), an underwater habitat offshore of Key Largo, Florida, and 14 natural reef sites spanning 4 habitats, on the surrounding Conch Reef. Food web models were created for ARB and natural reef habitats. Biomass at each habitat was quantified by fish surveys. Using Ecopath, species were organized into functional groups with supporting data from previous research for other inputs. ARB’s food web was found to have a large predator biomass with insufficient prey biomass to sustain the population, suggesting that these predators …

Monitoring Wading Bird Colonies Using Acoustic Sampling And Regional Shifts In Wading Bird Nest Abundances In A Pulsed Wetland System, Rachel C. Larson

Electronic Theses and Dissertations 2020 - Present

Wetland loss and degradation have led to the development of restoration programs worldwide, many of which monitor wading bird populations as indicators of wetland quality. Therefore, efficient, standardized monitoring is integral to restoration progress. I tested the use of passive acoustic monitoring to estimate nest abundances and provisioning rates in wading bird colonies and examined regional nesting dynamics in the Florida Everglades, where a long monitoring record enables analysis of nesting patterns relative to hydrologic changes. I found that call rates can serve as indices of colony nest abundances and begging call rate and timing are indicative of provisioning events. …

Photoreceptor Degeneration And Abnormal Retinal Vasculogenesis, Matthew Nguyen

Electronic Theses and Dissertations 2020 - Present

Abnormal vasculature in the retina, specifically tortuous blood vessels, are common to many of the most prevalent retinal degenerative diseases currently affecting millions across the world. The mechanisms of their formation and development in the context of retinal degenerative disease, however, are still poorly understood. The rd1 and rd10 mice are relatively well-studied animal models of retinal degenerative disease, however, there lacks a systematic characterization of vascular changes co-related to photoreceptor degeneration in the rd1 and rd10 retina. Here, we utilize advancements in confocal microscopy, immunohistochemistry, and image analysis software in order to systematically characterize vascular changes before and after …

Confirmation Of New Crapemyrtle Bark Scale (Acanthococcus Lagerstroemiae) Hosts (Spiraea And Callicarpa) Through Dna Barcoding, Allen Szalanski

Entomology and Plant Pathology Faculty Publications and Presentations

Crapemyrtle bark scale (CMBS; Acanthococcus lagerstroemiae Kuwana) is an invasive insect that was first discovered in the United States in 2004. The polyphagous feeding habit of CMBS has allowed it to infest a wide range of plant species beyond its primary host, Lagerstroemia. Using molecular approaches, we studied the genetic relationships between CMBS specimens and their hosts from different geographic locations. Naturally occurring CMBS infestations were confirmed on American beautyberry (Callicarpa americana L.), a native plant species in the United States, and spirea (Spiraea L.). The new infestation of CMBS found on Spiraea raises the alarm that other economically important …

Isolation Of Metarhizium Guizhouense And Metarhizium Robertsii Strains From Soil-Exposed Amblyomma Americanum (Acarina: Ixodidae) From Northwest Arkansas, Usa, Allen Szalanski

Entomology and Plant Pathology Faculty Publications and Presentations

The lone star tick, Amblyomma americanum (L.) (Acarina: Ixodidae), is the most abundant tick species found in Arkansas and is involved in the trans-mission of pathogens of medical and veterinary importance. When not feeding, most non-nidicolous tick species shelter in the soil and leaf litter where they may be exposed to and potentially infected with entomopathogenic fungi that reside naturally in the soil. Entomopathogenic fungi in the genus Metarhizium Sorokīn (Hypocreales: Clavicipitaceae) have shown promise as biological control agents of ticks. Here, the first study to isolate and identify Arkansas-derived isolates of Metarhizium from A. americanum ticks is presented. We …

A Role For Endothelial Tissue-Nonspecific Alkaline Phosphatase In Blood-Tissue Barrier Health And Disease, Allison L. Brichacek

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sepsis is a disorder that targets the microcirculation with significant effects at blood-tissue barriers such as the blood-brain barrier (BBB) and gut-vascular barrier (GVB). Intestinal barrier dysfunction is thought to be one of the most important contributors to multi-organ dysfunction in sepsis. As a common site of infection, the impaired gut allows the dissemination of bacteria, which exacerbates the disease pathophysiology, and can lead to long-term morbidity and mortality. The mechanisms that influence altered barrier permeability in the GVB in sepsis and other inflammatory disorders are not well understood. Tissue-nonspecific alkaline phosphatase (TNAP) enzyme activity, which has been shown to …

Nuclear Aurora-A Kinase-Induced Hypoxia Signaling Drives Dissemination And Metastasis In Breast Cancer., Kristina Marinak Whately

Graduate Theses, Dissertations, and Problem Reports (ETD)

Metastatic breast cancer causes the vast majority of cancer-associated deaths, especially in triple negative breast cancers (TNBC). TNBC is still poorly understood and has no effective treatment. Here we reveal that presence of Aurora-A Kinase (AURKA) in the nucleus and metastatic dissemination are molecularly connected through HIF1 (Hypoxia induced factor-1) signaling. The nuclear AURKA in the complex with constitutively expressed HIF-1β subunit activates transcription of “hypoxia induced genes” under normoxic conditions (the phenomenon called pseudohypoxia) without upregulation of oxygen-sensitive HIF-1α subunit. We uncover that AURKA preferentially binds to and phosphorylates HIF-1β, and co-localizes with HIF complex on DNA. The mass …

Staying Power: Examining Resistance In West Virginia, Beth Nardella

Graduate Theses, Dissertations, and Problem Reports (ETD)

West Virginia has been plagued with high unemployment rates, high rates of addiction and poverty, and some of the worst health outcomes in the country. Outmigration has been the paradigm for many, but why do some people choose to stay? Numerous scholars have written about outmigration, but there is little information on why people stay. After decades of people leaving, many who remain have made a choice to stay. This choice can be seen as an act of resistance against the problematic discourses surrounding the Appalachian region and the economic disparities found within rural communities. West Virginians are often dependent …

Quantification Of Bacterial Shedding From The Respiratory Tract Of Health Care Workers Wearing Paprs And Other Types Of Air-Purifying Respirators On Sterile Conditions In A Simulated Operating Rooms (Ors), Segun Olanrewaju Ajewole

Graduate Theses, Dissertations, and Problem Reports (ETD)

The role of powered air- purifying respirators (PAPRs) in healthcare settings during infectious diseases outbreaks and highly contagious pathogens (e.g., SARS, HINI, Ebola, COVID etc.) has attracted much interest based on the level of respiratory protection they provide and their many positive user features. A common practice among healthcare workers to minimize airborne contaminant exposure has been to use surgical masks or N95 filtering facepiece respirators (FFRs). Surgical masks have been shown to offer minimal respiratory protection and while N95 FFRs offer better respiratory protection, they are not comfortable to use for a prolonged period. With current PAPR designs, exhaled …

The Impacts Of An Entrepreneurial Course On Secondary Students' Entrepreneurial Self-Efficacy And Entrepreneurial Intentions, Toi E. Hershman

Graduate Theses, Dissertations, and Problem Reports (ETD)

There is considerable agreement that promoting entrepreneurship stimulates economic development and job creation, which helps maintain a country’s economic competitiveness. Entrepreneurship education is a key to increasing the likelihood of potential entrepreneurs. While substantial research has documented strategies for enhancing students' entrepreneurial mindset and building entrepreneurial skills in higher education, entrepreneurship is rarely incorporated into or studied in secondary education. This mixed-method study examined the impact of an online ten-lesson entrepreneurship course on secondary students' entrepreneurial self-efficacy and entrepreneurial intentions. Students took a pre-survey that measured their entrepreneurial self-efficacy and intentions before the course and a post-survey upon completing the …

Predictors Of Courage In Adolescents, Yea Won Park

Graduate Theses, Dissertations, and Problem Reports (ETD)

Adolescence can be a difficult phase of life. Adolescents may experience drastic physical, psychological, social changes, which can lead to uncertainty and anxiety. Courage is an important construct to study because it could help adolescents carry out tasks, work more effectively, and pursue goals (Koerner, 2014). Few studies have investigated predictors of general courage (e.g., personality; Muris et al., 2009), and moral courage (i.e., parenting, gender; Bronstein et al., 2009). The present study examined intrapersonal and interpersonal predictors (Time 1) of courage (Time 3) among adolescents, as well as potential mediating and moderating mechanisms. Data were collected from a larger …

Determining The Effects Of Imidacloprid On Non-Target Soil Organisms In Hemlock Stands, Braley Burke

Graduate Theses, Dissertations, and Problem Reports (ETD)

The hemlock woolly adelgid (HWA), Adelges tsugae Annand (Hemiptera: Adelgidae), is an invasive insect that is causing mortality of eastern hemlock trees, Tsuga canadensis, and Carolina hemlock trees, Tsuga caroliniana, across the eastern United States. To protect these ecologically important tree species, a neonicotinoid insecticide, imidacloprid, is commonly used. Imidacloprid is an effective treatment and can remain effective against HWA for four to six years but long-term (≥ one year after application) non-target effects of imidacloprid on forest ecosystems are not well-studied. This study examined terrestrial non-target effects of imidacloprid in hemlock stands with different treatment histories to …

Graduate Theses, Dissertations, and Problem Reports (ETD)

ABSTRACT

AEROSOL SAMPLING STRATEGY: Effect of Particle Transfer to Sampler Covers and Estimation of Conversion Factors between the United States and German Methods for Quartz sampling

GODWIN A. EREKAIFE

In many countries, communities of experts, including industrial hygienists, have developed unique sampling strategies to determine workers’ exposure to aerosolized particles (e.g., metals, wood dust etc.). However, using different sampling and analytical methods for the same chemical often results in different exposure levels for a similar exposure group (SEG). The exposure discrepancies among different countries that are caused by using different measurement strategies are not always systematically defined. Therefore, this study …
