Mississippi was chosen based on its unique accountability model.

The survey method was used for this study. Over 100 school leaders from across the state participated from 12 different school districts. Their responses provided some indication of the differences that exist between “A” and “F” …

Receptor-Doped Organic Transistors: Transducing Anion Binding From Mixed Ionic-Electronic Transport, Anthony Benasco

Dissertations

Organic semiconductors based on π-conjugated polymers show remarkable properties such as high tolerance to structural defects, low processing temperature requirements, biocompatibility, ease of fabrication, and tunable properties. Conjugated polymers integrated into device arrays can exhibit collective properties sensitive to minor perturbations in the surrounding media. However, these devices rely on serendipitous sensitivity to the analyte of interest, and strategies for specific detection remain a considerable change. There remains a compelling, global need for technologies to monitor phosphate due to its prevalence in agricultural runoff, leading to fish kills and economic decline for commercial and recreational fisheries. The strong hydration energies …

Does Optic Flow Provide Information About Actions?, Hannah Masoner

Dissertations

Optic flow, the pattern of light generated in the visual field by motion of objects and the observer’s body, serves as information that underwrites perception of events, actions and affordances. This visual pattern informs the observer about their own actions in relation to their surroundings, as well as those of others. This study explored the limits of action detection for others as well as the role of optic flow. First-person videos were created using camera recordings of the actor’s perspective as they performed various movements (jumping jacks, jumping, squatting, sitting, etc.). In three experiments participants attempted to detect the action …

Posttraumatic Stress Symptoms, Anger, And Substance Use As Risk Factors For Trauma Revictimization, Hannah E. Walker

Dissertations

Maltreatment survivors are at an increased risk for adult revictimization. Yet, existing work has specifically focused on sexual revictimization, and it is unclear what factors increase one’s risk for revictimization more broadly. Posttraumatic stress symptoms (PTSS), anger, and substance use have been identified as potential risk factors for sexual revictimization. Still, the role of these variables is ambiguous in the broader revictimization framework. There is also a lack of understanding regarding the roles of the DSM-5 posttraumatic stress disorder (PTSD) symptom clusters and revictimization. This study aims to: 1) examine the links between maltreatment and revictimization and three factors (i.e., …

What’S Religion Got To Do With It?: Differing Religiosity Domains’ Association With College Students’ Sexual Consent During First-Time Intercourse, Kaylee Richmond

Dissertations

Within the U.S., 36% of women and 17% of men report experiencing sexual assault (Smith et al., 2017). The absence of sexual consent is often regarded as a defining component of sexual assault (Beres, 2014); thus, a potential area to examine to decrease rates of perpetration and victimization. To date, there has been a lack of research on contextual factors that are likely related to sexual consent, with a general focus on external consent (i.e., verbal/behavioral indicators; Muehlenhard et al., 2016). The present study examined the role of a contextual factor, religiosity, on sexual consent processes during the context of …

Creating, Destroying And Preserving Coherence With Quantum Channels, Masaya Takahashi

Dissertations

Quantum coherence is a fundamental property of quantum systems that can be studied within the framework of a quantum resource theory. In chapter 2, we consider how much coherence can be either generated or destroyed on a bipartite system when the action is restricted to local unitary operations. For pure states, we find that the relative entropy of entanglement and the robustness of entanglement provide tight lower bounds on the amount of coherence that can be destroyed by local unitaries, as measured by the relative entropy and L1 measures of coherence, respectively. We then study the amount of bipartite pure …

Are Natural Killer Cells Novel Mediators Of The Effects Of Cannabidiol On Mental Health, Sleep Quantity, Sleep Quality, And Immune Function?, Jacob Norbert Kisiolek

Dissertations

Cannabidiol (CBD) has increased in popularity since the United States Farm Bill legalized hemp production in 2018 and is now projected to become a $24.4 billion dollar industry by 2025. Since its legalization, CBD is thought to be an antiepileptic, anxiolytic, and antipsychotic, as well as an agent to improve mental health, quality of life, aspects of sleep and immune function. However, many of these claims lack scientific evidence. The purpose of this randomized, double blind, placebo-controlled trial was to determine the effects of an 8-week CBD intervention on measures of mental health, sleep quantity, sleep quality, and natural killer …

Effects Of Noise, Light, And Landscape On Birds In A Recently Urbanized County, Karina Alejandra Sanchez

Dissertations

Anthropogenic activities are drastically and rapidly altering ecosystems. Research has found that urban environments support less biodiversity than non-urban environments. This work has inspired recent interest investigating animal behavior and individual reproductive success in urban wildlife as mechanisms to why biodiversity is lower in urban areas. For my dissertation research, I used three key urban characteristics; noise, light, and landscape composition to study the effects of urbanization on avian species across Weld County, CO. I used these measurements to test the overarching hypothesis that urban land characteristics alter avian community structure and more specific hypotheses regarding how each factor (noise, …

Trauma And Alcohol/Substance Use: The Role Of Self-Regulation Flexibility, Saankari Anusha Challa

Dissertations

Despite a high comorbidity rate between trauma/PTSD and problematic alcohol/substance use, there is only a small body of work investigating moderators and mediators in this relationship. Few studies have examined the role of self-regulation, composed of coping and emotion regulation, in the context of PTSD and problematic substance use. Prior work has generally measured self-regulation categorically, with strategies labeled as maladaptive or adaptive, and therefore failing to account for the adaptiveness of the strategy in particular contexts. The present study is the only one to date to examine self-regulation flexibility in the relationship between posttraumatic symptoms (PTSS) and problematic alcohol/substance …

Promoting Safe Sleep Education For At Risk Mothers, Breanna James

Dissertations

Sudden infant death syndrome (SIDS) is an unexplained scary phenomenon that has plagued parents for years until research determined there was a link between the infants sleeping position and sudden death. Local community leaders in health and advocacy review fetal and infant deaths on an annual basis to identify ways that infant mortality may be prevented. Barriers related to social determinants of health and lack of knowledge specific to safe sleep were identified root causes. Evidence-based recommendations for safe sleep set forth by the American Academy of Pediatrics have demonstrated effectiveness in reducing mortality. The purpose of the quality improvement …

Interspecific Pollen Transfer, Gene Flow, And Speciation In Bat-Pollinated Burmeistera H. Karst. & Triana (Campanulaceae: Lobelioideae), Juan Moreira-Hernandez

Dissertations

The evolutionary success of angiosperms has been largely influenced by their interactions with animal pollinators, which provide pollen and gene transport between individuals, populations, and young diverging species. Here, I examine the interplay between interspecific pollen transfer (IPT) by shared pollinators, gene flow, and the evolution of reproductive isolation in the young rapid radiation of Neotropical bat-pollinated bellflowers in the genus Burmeistera (Campanulaeae: Lobelioideae). In Chapter 1, I conducted an extensive review of the pollination and plant speciation literature to highlight the evolutionary consequences of IPT in angiosperms and showed that it has profound consequences for the evolution of floral …

Roles Of Phospholipase Dε In Arabidopsis And Soybean Response To Nitrogen Deficiency, Shuaibing Yao

Dissertations

Phospholipase D (PLD) hydrolyzes phospholipids to produce phosphatidic acid (PA) and plays important roles in plant growth, development, and stress response. Of 12 PLDs in Arabidopsis, PLDε is involved in nitrogen response in Arabidopsis and canola, but the mechanism remained elusive. This study was undertaken to investigate how PLDε mediates plant response to nitrogen availability. Nitrogen deficiency induces an increase in PLDε transcript and protein levels and an increased association with intracellular membranes. PLDε interacts with autophagy-related protein 8e (ATG8e), and two of the four predicted ATG8-interacting motifs in PLDε are required for PLDε-ATG8e interactions. PLDε hydrolyzes phosphatidylethanolamine (PE) conjugated …

Factors Associated With Household Contacts' Tuberculosis Testing And Evaluation, Elvy G. Barroso

Dissertations

Contact investigation (CI) is one of the core elements of tuberculosis (TB) control. It is intended to achieve early identification of contacts who may have been exposed to a patient with infectious active TB and contacts who may benefit from treatment for latent tuberculosis infection (LTBI). LTBI is an infection in which the Mycobacterium tuberculosis organisms cause no signs and symptoms but the infection can be reactivated and develop into full-blown active TB disease. Failure to be identified as a contact is the primary reason for disease development in more than half of TB patients, thus a complete and timely …

Sexual Minority Thriving: Bouncing Beyond Adversity, Debra Crawford

Dissertations

Sexual minority individuals continue to face prejudice and discrimination due to their sexual minority identity. However, despite these negative experiences, many sexual minority individuals display resilience and thrive. Most of the literature on sexual minorities focuses on negative aspects of identifying as a sexual minority, rather than the positive qualities that these individuals possess that allow them to persevere. In a sample of 303 sexual minorities, this dissertation contained two studies. Study one investigated if posttraumatic growth mediated the relationship between resilience and thriving and if identity pride and existential anxiety moderated the relationship between resilience and thriving in a …
