“I Done Been Through Hell”: An Existential Phenomenological Study Of The Lived Experience Of Fathers Who Have Lost A Child, Dynisha Wigginson

Electronic Theses and Dissertations

The rise in American pediatric death led to a shift in pediatric end-of-life care from focusing care only on the dying pediatric patient to include focus on the family. Most literature has focused only on mothers’ experiences or the combined experiences of mothers and fathers. Fathers’ experiences at their child’s end of life, as an individual phenomenon, is overlooked and ignored. Hence, significant knowledge gaps exist related to the repeated exclusion of fathers’ individual experiences. This study aimed to begin to fill this gap. Using the lens of Merleau-Ponty, this existential phenomenological study aimed to describe the lived experiences of …

A Phenomenological Inquiry Exploring Parental Involvement At Alternative Schools In Eastern North Carolina, Irv Glenn Ii

Electronic Theses and Dissertations

The purpose of this phenomenological study was to discover the perceptions of caregivers and teachers regarding parental involvement at alternative schools in Eastern North Carolina. The lack of parental involvement at some schools is a systemic issue that involves continued efforts by school staff to include caregivers in promoting student success. The difficulties of engaging parents of alternative students result in little interaction between caregivers and educators. It is essential to understand how caregivers and educators perceive parental involvement and assess the quality of parental participation in an alternative educational setting. A qualitative research method was chosen to comprehensively examine …

Not All Pollinator Gardens Are Created Equally: Determining Factors Pertinent To Improving Pollinator Garden Effectiveness, Travis Watson

Electronic Theses and Dissertations

Increasing evidence documenting the decline of insect populations, resulting from increasing human disturbances has resulted in efforts to establish pollinator gardens to provide additional resources for insect populations. However, our understanding of biotic and abiotic garden characteristics important for attracting and sustaining pollinator diversity is limited. Here, we evaluated 17 pollinator gardens to evaluate the effect of five biotic and three abiotic garden characteristics on pollinator species richness, abundance, and proportional representation of four pollinator functional groups. Plant species richness positively influenced pollinator richness and negatively influenced flower visitation. Bombus proportional abundance responded to several variables (distance to vegetation, plant …

The Loss-Processing Framework, Lawrence Childress

Electronic Theses and Dissertations

The circumstances of responding to loss due to human death are among the most stressful experiences encountered in life. Although grief’s symptoms are typically considered essential to their gradual diminishment, possible negative impacts of complications related to grief are also well known, and have been associated with detriments to mental and physical health. Grief, however, can also generate transformative positive change. Thus, albeit ineludible, responding to loss is not uniformly experienced, expressed, or understood. It is also culturally-shaped, making attempts to define “normal” grief, as well as to label some grief “abnormal”—and to medicalize it—possibly problematic. Bereavement (the situation surrounding …

Hemin Utilization In Rhizobium Leguminosarum Atcc 14479, John Lusby

Electronic Theses and Dissertations

Rhizobium leguminosarum is a Gram negative, motile, nitrogen-fixing soil bacterium. Due to the scarcity of iron in the soil bacteria have developed a wide range of iron scavenging systems. The two types of iron scavenging systems used are indirect and direct. In-silico analysis of the genome identified a unique direct iron scavenging system the Hmu operon. This system has been identified in other closely related rhizobium species and is believed to be involved in utilizing heme compounds as a sole source of iron. We have attempted to characterize the role of the Hmu operon in iron utilization by monitoring the …

“We Just Didn’T Talk About It:” Strategies Of Stigmatized Grief Management, Claire D. Selleck

Electronic Theses and Dissertations

This study explores the experiences of people who have lost loved ones due to socially stigmatized deaths. Drawing from eight individual interviews, the author argues that the stigma associated with death due to drug overdose, suicide, substance abuse, or murder can cause traumatic or prolonged grief and can complicate the way the bereaved talk about grief as a part of their healing process. With the mortality rate in the U.S. rising, there is an epidemic of disenfranchised grief affecting millions of bereaved individuals. Using Coordinated Management of Meaning and Communication Privacy Management theories, the author uncovers strategies the traumatically bereaved …

Effects Of Respiratory Perturbations On Aging And Healthspan In Daphnia Magna, Millicent Nkiruka Ekwudo

Electronic Theses and Dissertations

Aging is a degenerative process characterized by a decline in physiological functions and cellular activities. Environmental and pharmacological interventions affecting longevity pathways have been extensively studied in model organisms. This study investigated the effect of chronic mild intermittent hypoxia (4 mg O2/L) or mild mitochondrial uncoupling with three doses of 0 (control), 0.1, 1, and 5 μM of 2,4-Dinitrophenol (DNP), on life history and gene expression in four clones of Daphnia magna. Interestingly, clones from intermittent ponds displayed better tolerance to hypoxia and DNP. Although neither treatments extended longevity, hypoxia increased fecundity and body size, and decreased food consumption and …

The Failure Of Chivalry, Courtesy, And Knighthood Post-Wwi As Represented In David Jones’S In Parenthesis, Taylor L. Hubbard

Electronic Theses and Dissertations

This thesis analyzes David Jones’s In Parenthesis to demonstrate the failed notion of chivalry, courtesy, and knighthood in modernity during and after the war. Jones’s semi-autobiographical prose poem recounting his experiences of WWI was published in 1937, nineteen years after the war ended. Jones applied the concepts of chivalry, courtesy, and knighthood to his experiences during WWI through In Parenthesis. Jones used these concepts, which originated in the classical period and the Middle Ages, to demonstrate how they have changed over time, especially given the events of WWI. The best way for Jones to demonstrate the impact of WWI …

Identification Of Transcription Regulators Of The Algz/R Two-Components Regulatory System In Pseudomonas Aeruginosa, Kwasi Yeboah

Electronic Theses and Dissertations

Pseudomonas aeruginosa is an opportunistic pathogen that express a plethora of virulence components controlled through two-component regulatory systems that allow for sensing and responding to environmental stimuli. This study was aimed at identifying transcription regulators of algZ that encodes the histidine sensor kinase (AlgZ) of the AlgZR two-component regulatory system. To understand how the algZ gene is transcriptionally controlled, transposon mutagenesis was used to create a mutant library with varying algZ expression based on their b-Galactosidase activity. The gene PA3327 was identified as a potential regulator of algZ expression using arbitrary PCR. This gene encodes a probable non-ribosomal peptide synthetase …

The Effects Of Virtual Nature Exposure On State Social Motivation, Samantha A. Castelblanco

Electronic Theses and Dissertations

Social health is an important predictor of overall health. Yet, it is an often neglected area of research. Strikingly, social connectedness is associated with a 50% reduction in risk of early death. While a plethora of research evidence supports the beneficial impact of nature exposure on physical and mental health, literature regarding the beneficial impact of nature exposure on social health is scant. In fact, no research to date has investigated the causal influence of nature exposure on social motivation, a construct comprised here of three measures (State Motivation to Foster Social Connections, State Positive Affect, and State Anxiety). The …

Intrinsic Religiousness And Its Relation To Health Outcomes, Joseph Barnet

Electronic Theses and Dissertations

Religiousness, broadly defined, has been shown to be predictive of a variety of health outcomes. Past literature surrounding religiousness research has utilized different definitions and measures for the meaning of religiousness. How religiousness is defined can influence its relationship in relation to health outcomes. The present study utilized a measure for intrinsic religiousness, which is defined as an internalization of the tenets of a particular faith. The present study examined whether intrinsic religiousness predicts problematic or illicit substance use or pornography use in a sample of participants that included mostly undergraduate students from the Appalachian region, as well as some …

Profiling Beyond Race: Characteristics Associated With Traffic Stop Outcomes, Megan Anderson

Electronic Theses and Dissertations

Research related to profiling and the outcome of traffic stops has generally focused on the race of the individuals involved. Little research has examined other characteristics, such as age and socioeconomic status, that may also play a role in traffic stop outcomes. The current study sought to address this limitation in two ways: (1) determine whether the characteristics of age, sex, race, social class, and demeanor are profiled during traffic stops and (2) whether these characteristics influenced the outcome of the traffic stops with regard to tickets and vehicle searches. Secondary data were utilized from the 2015 Police-Public Contact Survey. …

It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey

Electronic Theses and Dissertations

The role of adverse childhood experiences (ACEs) and criminal thinking in causing criminal behavior has been explored extensively in criminal justice research. Based on the concepts of ACEs and the Psychological Inventory of Criminal Thinking Scale, the negative parental influences and criminal thinking styles of 1,354 juvenile offenders were examined to establish that negative parental influences and criminal thinking are separately associated with juvenile problem and offending behavior, and that criminal thinking mediates the relationship between negative parental influences and juvenile problem and offending behavior. Analyses showed support for criminal thinking as a pathway from negative parental influences to juvenile …

A New All-Natural Wound Treatment Gel Shows Strong Inhibitory Activity Against Staphylococcus Aureus And Other Wound Pathogens, Tasha K. Nelson

Electronic Theses and Dissertations

Skin related injuries are some of the most dangerous forms of wounds. In addition to treating the wound itself, health care providers must be cautious of microbial infections. In this study, we evaluate a novel all-natural antimicrobial gel compound (AMG) designed to kill planktonic bacteria, penetrate bacterial biofilms, and accelerate wound healing. In -vitro experiments demonstrate that AMG is effective in inhibiting planktonic growth and biofilm development of eight common pathogens. LIVE/DEAD staining and confocal microscopy reveal that planktonic growth and three-dimensional structure of biofilms were significantly reduced. Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) was used to investigate a small …

Investigating The Association Between Adolescent Polysubstance Use, Crime, And Violence In The United States, Christian Nwabueze

Electronic Theses and Dissertations

The lifetime prevalence of alcohol in the United States is 8% and lifetime prevalence of illicit drug use is about 2-3%. Substance use is common among adolescents and polysubstance use is becoming a public health threat.

The prevalence of adolescent physical dating violence was 8.2%, the prevalence of adolescent sexual violence was also 8.2% while the prevalence of dual adolescent physical and sexual violence was 2.6%. Compared to those who used only single substances, adolescents who did not use any substance were 60% less likely (OR = 0.42, 95% CI = 0.24 – 0.74) to experience physical dating violence, 50% …

Identity-Specific Positive Psychology Intervention For Sexual Minorities: A Randomized Control Trial, Sarah Job

Electronic Theses and Dissertations

Sexual minorities experience mental and physical health disparities in comparison to heterosexual individuals due to minority stress (Branstrom et al., 2016; Kerridge et al., 2017; Meyer, 2003). Positive psychology interventions have improved mental and physical health (Antoine et al., 2018; Lambert D'raven et al., 2015), and therefore these interventions have potential to address health disparities. The current study tested an identity-specific intervention (n = 30) to a general positive psychology intervention (n = 30) and a control group (n = 30) among sexual minorities. This built on a recent pilot study which tested the efficacy of an …

Constructions & Optimization In Classical Real Analysis Theorems, Abderrahim Elallam

Electronic Theses and Dissertations

This thesis takes a closer look at three fundamental Classical Theorems in Real Analysis. First, for the Bolzano Weierstrass Theorem, we will be interested in constructing a convergent subsequence from a non-convergent bounded sequence. Such a subsequence is guaranteed to exist, but it is often not obvious what it is, e.g., if an = sin n. Next, the H¨older Inequality gives an upper bound, in terms of p ∈ [1,∞], for the the integral of the product of two functions. We will find the value of p that gives the best (smallest) upper-bound, focusing on the Beta and Gamma integrals. …

Advance Care Planning Protocols And Hospitalization, Rehospitalization, And Emergency Department Use In Home Health, Sharon Bigger

Electronic Theses and Dissertations

Aim. The aim of this study was to examine the relationship of advance care planning protocols with hospitalization, rehospitalization, and emergency department use rates in U. S. home health agencies (HHA).

Background. Since 2003, CMS has required HHAs to report on quality outcomes such as hospitalization, rehospitalization, and emergency department use rates, made publicly available online. Advance care planning (ACP) is a conversation about beliefs, goals, values, future treatment choices, and designation of a surrogate decision-maker, that someone has in advance of a health crisis. Most existing studies on ACP have taken place outside of HHAs among populations with serious …

“It Could Have Happened To Any Of You”: Post-Wounded Women In Three Contemporary Feminist Dystopian Novels, Abby N. Lewis

Electronic Theses and Dissertations

My goal for this thesis is to investigate the concept of (mis)labeling female protagonists in contemporary British fiction as mentally ill—historically labeled as madness—when subjected to traumatic events. The female protagonists in two novels by Sophie Mackintosh, The Water Cure (2018) and Blue Ticket (2020), and Jenni Fagan’s 2012 novel The Panopticon, are raised in environments steeped in trauma and strict, hegemonic structures that actively work to control and mold their identities. In The Panopticon, this system is called “the experiment”; in The Water Cure, it is personified by the character King and those who follow him; …

Electronic Theses and Dissertations

This study examines the work of single, white, middle-class women feeding and caring for their families during the COVID-19 pandemic in the year 2020. The study draws from qualitative analyses of one-on-one interviews conducted with seven single mothers. After situating single mothers and family food provision in the academic literature, as well as and current knowledge about the pandemic in the U.S., the author explores ways that the pandemic disrupted family life. Findings indicated that the single mothers were keenly impacted by being cut off from child care, schools, and other social connections they needed to maintain employment. Further, their …

Teachers’ Stress, Anxiety, And Depression: What Are Special Education Teachers Experiencing?, James H. Potter

Electronic Theses and Dissertations

Research has shown that people in the teaching profession have high levels of stress and often report increased levels of symptoms of anxiety and depression. Students’ academic progress may have adverse effects when their teachers have high-stress levels or report mental distress. Those who teach special education often face high levels of stress. However, there is little research considering special education teachers’ job-related health. This study collected data on 598 general and special education teachers in the United States. This study compared the endorsements of both stress and psychopathology between special education and general education teachers. This research found that …
