Development And Validation Of The Measure Of Perceived Safety In The College Classroom: A Mixed Methods Phenomenological Research Study., Jennifer Ballard-Kang

Electronic Theses and Dissertations

In recent years, safety has become a focus of discussion in the field of higher education as research indicates that college students’ perceptions of safety are related to several indicators of student engagement. Despite increased recognition of the importance of safety, there remains a lack of consensus with regard to its definition and conceptualization in the higher education context. This lack of a conceptualization of safety that reflects the complexity of the construct within the postsecondary context has acted as a barrier to the development of quality measurement instruments that can be utilized by researchers and practitioners to understand and …

Coparenting And School Success: Perspectives Of Fathers., Shannon M. Mount

Electronic Theses and Dissertations

Historically, measures of coparenting have been reported by mothers. As a result, fathers’ perspectives and experiences have largely been excluded from this body of research. In response, this study relies on fathers own report of coparenting support. This study used a sample of 1255 biological fathers from the Fragile Families and Child Wellbeing Study (FFCWS) to explore fathers’ reports of their coparenting support and how this is associated with relationship status with mother, time spent with child, and several school success variables including: internalizing and externalizing school behaviors and math and reading assessment scores at child age 9. Hypotheses included …

Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman

Electronic Theses and Dissertations

Soil erosion is of escalating importance as increasing population and climate change have put increasing pressures on agricultural food production. Vegetation and precipitation are two factors that control the amount of soil erosion extant within a region. Sediment delivery ratios (SDRs) assess the ratio of soil eroded from a watershed system that is permanently removed from the system through stream sediment discharge. Using 1) river discharge and sediment concentration data and 2) the Revised Universal Soil Loss Equation (RUSLE), this thesis analyzes fluctuations in monthly SDRs for an average hydroclimatological crop-harvest season for the Senachwine Creek watershed, IL. Through calculating …

A linkage between the stereotypes and Olivia Pope’s character will be made based on an analysis of the television show. A random sampling approach was used to select a total of 14 episodes. Each of the 14 episodes were carefully examined for examples of Mammy-like, Jezebel-like, and Sapphire-like …

Reactive And Regulative Temperament Dimensions, Emotion Regulation, And Concurrent Internalizing And Externalizing Pathology Among Youth With Adhd., Kirsten D. Leaberry

Electronic Theses and Dissertations

Emerging research has increasingly identified the detrimental effect of internalizing and externalizing comorbidity on the functioning of youth with Attention-Deficit/Hyperactivity Disorder (ADHD). Research in the broad child psychopathology literature has identified a variety of dispositional and developmental risk factors for psychopathology development in youth. However, a conceptual model of psychopathology development has yet to be developed and empirically evaluated in an ADHD sample. Children with ADHD may be particularly vulnerable to exhibiting high rates of psychopathology, given deficits in self-regulation prevalent in this population. The current study proposed and evaluated a theoretical model of distal and proximal risk factors for …

To evaluate chemical tracing, Fluoro-Ruby (FR) was injected at the level of the axon terminals, and the number of ipsilateral labeled cell bodies at lumbar level was quantified. Similarly, two dual-viral systems were evaluated, by either injecting retro-AAV-Cre or HiRet-Lenti-Cre unilaterally in combination with a Cre-dependent adeno-associated virus. The HiRet-Lenti and FR groups labeled significantly greater …

Determination Of Selenite And Selenate In Wet Flue Gas Desulfurization Process Water Through Ic-Icp-Ms And Hg-Icp-Aes, Samuel Anthony Kelty

Electronic Theses and Dissertations

During coal-fired electric power production, coal bound elemental selenium is released into the gas phase and oxidized to selenite and selenate in the wet flue gas desulfurization (WFGD) unit. Selenite and selenate solubilize in the WFGD process water. A process water system at a coal fired power plant contributes to environmental regulation compliance by removing the selenium species from WFGD process water. A selenium speciation method was developed for the purpose of better monitoring the selenium species present in the “treated” process water and to aid the process water system in meeting compliance with the Environmental Protection Agency’s Effluent Limitation …

"No One's Gonna Say That At Church:" Women's Experiences With Infertility In Christian Faith Communities, Donna Paulsen

Students’ Perceptions Of Campus Sexual Assault Resources: An Appalachian Perspective, Rychelle Moses

Electronic Theses and Dissertations

Research relating to campus sexual assault has traditionally focused on its prevalence and factors that serve to influence risk of victimization. Less attention has been directed toward the presence and effectiveness of campus sexual assault resources. In addition, few studies have explored the role that culture and other geographical factors may play in this process. The current study seeks to address this limitation in two unique ways: (1) determining whether an Appalachian upbringing influences knowledge of and willingness to utilize campus sexual assault resources and (2) exploring its impact on adherence to common rape myths. Survey data are gathered from …

Mesoporous Adsorbents For Perfluorinated Compounds, Bertha Lotsi

Electronic Theses and Dissertations

Effective adsorbents for polyfluorinated compounds (PFCs) were successfully prepared. And they were tested in the adsorption of perfluorooctanoic and perfluorooctanesulfonic acids. Bridged silsesquioxanes containing secondary and tertiary amino groups were synthesized by sol-gel condensation of bis[3-(trimethoxysilyl)propyl]amine and bis[3-(methylamino)propyl]-trimethoxysilane in acidic media with surfactants. Obtained materials are mesoporous with a high BET surface area. They combine high structural stability with a high concentration of surface amino groups serving as adsorption sites. Batch adsorption tests demonstrated their extremely high adsorption capacity on PFCs: in some experiments, it reached up to 88% of the adsorbent weight. Adsorption of PFCs changed the surfaces of …

“A Lot Of Prayer, And Some Wine In-Between”: Applying The Relational Turbulence Model To The Stepparent-Biological Parent Marriage., Paul Taylor

Electronic Theses and Dissertations

The present study utilizes the relational turbulence model (RTM) to illuminate stepparent experiences of relational uncertainty and partner interference within the context of the stepparent-biological parent marriage. In-depth, semi-structured interviews with 6 stepparents revealed four primary themes pertaining to how stepparents experienced relational uncertainty: (a) enactment of parenting, (b) competing expectations, (c) shifts in attitude and behavior by spouse, and (d) differences between marriage partners. Interference from partners was experienced by stepparents in relation to the enactment of parenting and the maintaining of the marriage as an intimate relationship.

Health Communication Via Social Media: How Pharmaceutical Companies Are Using Instagram For Corporate Social Responsibility, Abisoluwa Akinboboye

Specifically, how personality traits, ideational fluency, remote association ability, years of coaching experience, and work climate related to creative product impact and frequency. A modified creativity personality test was found to be positively …

Computational Quantum Study Of Intermediates Formed During The Partial Oxidation Of Melatonin, Oladun Oladiran

Electronic Theses and Dissertations

Melatonin is a neurohormone produced by the pineal gland in the brain. It functions as an antioxidant to scavenge free radicals. Free radicals are reactive species; they often oxidize the cells leading to oxidative stress which may lead to severe health complications. Reaction of melatonin with free radicals is known to be stepwise, as such the stability of the intermediates can be examined. Thus, the possibility of using melatonin as an in vivo spin trap can be determined. Spin traps allow characterization of unstable radical species using electron spin resonance spectroscopy. In this research, ab initio quantum chemistry techniques were …

A Replication And Extension Of A Prediction Tool Identifying Need For Treatment Among Opioid Exposed Infants, Loni Parrish

Electronic Theses and Dissertations

The incidences of maternal opioid use and neonatal opioid withdrawal syndrome (NOWS) have increased by nearly 400% over the past decade. Isemann and colleagues (2017) developed prediction tools (TiTE/TiTE²) to differentiate, within the first two days of life, between infants who will require pharmacotherapy for NOWS from those infants who will not require pharmacotherapy for NOWS. The goal of the current experiment was to replicate and extend their prediction model. The present experiments successfully replicated Isemann et al., (2017) results and also established alternative cutoff values for requiring treatment that provide better balance between all four metrics. Moreover, …

Emotional Appeals In Nonprofit Advertising: A Rhetorical Analysis Of Print Ads By The Susan G. Komen Breast Cancer Foundation And The American Cancer Society, Dominique N. A. Harrison

Electronic Theses and Dissertations

Emotional appeals are frequently employed in strategic messaging by nonprofit organizations. In this study, I identify instances of emotional appeals in select print adverts of the Susan G. Komen Breast Cancer Foundation and the American Cancer Society, and use rhetorical analysis to explore how each organization’s tactics are strategic in their appeal to target audiences’ emotions. In doing so, I identify several reoccurring emotional themes—including hope, love, and unity—that engage their target audiences and persuade them to respond to diverse calls-to-action. In order to make these appeals to audience emotion, the adverts employ rhetorical devices such as personification, metaphor, repetition, …

Efficient Conditional Inactivation Of Rdh10 Reveals Important Role Of Retinoic Acid During Lung Branching Morphogenesis., Nhut Quang Huy Tran

Electronic Theses and Dissertations

Birth defects are complicated pathological processes. Many birth defects can be traced back to disrupted regulation of molecular signaling pathways during embryogenesis. One of the most important gene regulatory factors during embryo development is retinoic acid (RA). However, studying the specific roles of RA in each organ during embryogenesis in vivo is challenging. The Sandell laboratory has a conditional mutant mouse model that can potentially be used for studying the role of RA during embryogenesis by inducing stage-specific RA deficiency. This model allows retinol dehydrogenase 10 (Rdh10), a gene required for RA production, to be inactivated at a …

Alcohol Consumption In A Preclinical Model Of Schizophrenia, Liza Hernandez

Electronic Theses and Dissertations

Schizophrenia is a debilitating psychiatric disorder that affects approximately 1% of the global population. Schizophrenia is highly comorbid with other psychiatric disorders such as Alcohol Use Disorder (AUD) with a prevalence rate of 27% - 65%, which is significantly higher than AUD exhibited by the general population (6%). Research indicates that a higher rate of AUD in individuals suffering from schizophrenia may be related to the common neuronal pathways that underlie the expression of both disorders. The present study will determine whether the neonatal quinpirole (NQ) rodent model of schizophrenia will approximate the human condition and exhibit increased EtOH consumption. …

Weight Status As A Moderator Of Low Self-Esteem And Poor Sexual Functioning, Madison Hinkle

Electronic Theses and Dissertations

Researchers have found that self-esteem and weight status can impact numerous aspects of an individual’s life, including reproductive health issues. However, there has been limited research specifically examining how self-esteem may affect female sexual functioning. The current study aims to examine whether self-esteem is a significant predictor of sexual functioning, and whether this relationship may change as a function of women’s weight status. Participants consisted of 730 women ranging from 18 to 49 years of age, who were recruited through an online questionnaire. Results indicate that higher levels of self-esteem predict better sexual functioning and weight status was found to …

The Experiences And Well-Being Of Mexican Immigrant Women Living In Traditionally Non-Latinx Communities In Western North Carolina, Melinda Bogardus

Electronic Theses and Dissertations

North Carolina has, in recent decades, experienced significant growth in its Latinx, and more particularly Mexican immigrant population. As a traditionally non-Latinx state, or a state without a long-standing, large Latinx population, many communities and healthcare and service providers within North Carolina still lack knowledge, resources, and skills needed to serve and support Latinx immigrant populations well. Guided by interpretive description, this qualitative study on Mexican immigrant women in Western North Carolina sought to gain knowledge and understanding of what it is like for them to live in a traditionally non-Latinx region and how immigration has affected their well-being. Asking …

Religion, Health, And The Spiritual But Not Religious, Alexander L. Smith

Electronic Theses and Dissertations

Previous literature shows an overwhelmingly positive relationship between religiosity and health. Researchers theorize that service attendance, social capital, and group identity verification mediates this positive relationship. There is an upward trend in secularity in the U.S. with more individuals describing themselves as spiritual but not religious (SBNR).Current research does not clearly depict who comprises the SBNR or how varying degrees of secularity fit into the relationship between religion and health. Using data from the GSS, this study examines basic sociodemographic characteristics of the SBNR and compares the SBNR to other religious and secular groups on various health measures. This study …

Behavioral And Neurobiological Evidence Of Epigenetic Transmission In The Neonatal Quinpirole Rodent Model Of Schizophrenia, Wesley Gill

Electronic Theses and Dissertations

Quinpirole is a dopamine D2 receptor agonist that if administered to rats from postnatal day (P)1-21 results in increased dopamine D2 receptor sensitivity throughout the animal’s lifetime. This increase in receptor sensitivity is consistent with schizophrenia. This model has additional consistencies with human schizophrenia, including sensorimotor gating deficits, enhanced behavioral and neurobiological responses to nicotine, and protein alterations consistent with the disorder. In this study, a second generation of the neonatal quinpirole (NQ) rodent model was created to investigate if long term changes caused by NQ treatment would be passed to offspring. NQ treated rats were mated and their offspring …
