The relationship between grade configuration and the percent of students who scored on track or mastered in English language arts and math was analyzed using an independent samples t-test. Further disaggregating by specific grade levels, grade configuration and …

We All Need Somebody To Lean On: Social Support As A Protective Factor For Individuals With Childhood Adversity, Rachel Clingensmith

Electronic Theses and Dissertations

Extensive research has shown that childhood adversity impacts development across the lifespan and has been linked to numerous negative health outcomes. Depression symptoms are one such outcome that has been associated with ACE exposure. The literature also indicates emotion regulation may be a mediator between ACEs and depression outcomes. The primary aim of this study (N = 766) is to investigate pathways leading from ACEs to depression and potential protective factors. It was hypothesized that difficulties in emotion regulation would mediate the link between ACEs and later depressive symptoms, social support would moderate the pathway between difficulties in emotion regulation …

Exploration Of Ataxia Telangiectasia And Rad3-Related’S (Atr’S) Role In Cell Death Regulation: Implications In Development, Cancer, And Stroke, Brian Cartwright

Electronic Theses and Dissertations

From gametogenesis until death an organism’s genome is under constant bombardment from endogenous and exogenous sources of DNA damage. To maintain genomic integrity amid this damage, cells have evolved responses which allow them to either preserve viability for recovery or initiate self-destructive pathways depending on the severity of DNA damage. One protein involved in initiating and carrying out these responses is the protein kinase ataxia telangiectasia and Rad3-related (ATR). ATR is known primarily for its regulatory role in initiating the checkpoint-signaling cascade following DNA damage and replicative stress. These signaling events lead to cell cycle arrest, DNA repair, or apoptosis …

Adverse Childhood Experiences, Familial Emotion Socialization, And Adult Emotion Regulation: A Moderation Model, Rebecca Otwell-Dove

Electronic Theses and Dissertations

Adverse childhood experiences (ACEs) have been associated with maladaptive outcomes, including difficulties with emotion regulation (ER). ER difficulties, in turn, increase risk for experiencing physical and mental health problems. Parental emotion socialization is one factor that has been associated with ER skills across development. No known studies, however, have examined whether parental emotion socialization moderates the relationship between ACEs and ER difficulties. In the current study, undergraduates (N = 678) completed questionnaires about their history of ACEs, parental emotion socialization experiences, and current ER difficulties. Correlational results indicated a positive correlation between ACEs and ER difficulties. Results of the hierarchical …

Chromatographic purification yielded a pure sample at 58.90 minutes, RT.58. HRMS data deduced an exact mass of …

An Exploratory Study Of Duty-Related Stress Among Conservation Officers, Logan Ledford

Electronic Theses and Dissertations

Research relating to police stress has typically focused on officers working in urban areas, neglecting their rural counterparts. This is especially true of conservation officers, who are tasked with enforcing laws in state parks and other recreational areas. To date, only a handful of studies have sought to better understand their experiences and perceptions. The current study seeks to further our understanding of conservation officer stress in three unique ways: (1) via applying McCreary and Thompson’s (2006) operational police stress scale (PSQ-Op) to the population, (2) determining whether officer characteristics (e.g., age, education, length of service) affect perceived stress, and …

Preparation Of Folic Acid-Carbon Dots-Doxorubicin Nanoparticles As Targeting Tumor Theranostics, Samson Dada

Electronic Theses and Dissertations

Carbon dots (CDs) have attracted much attention as an excellent gene/drug delivery and biological imaging agent for early cancer theranostics. In this study, we prepared two series of nanoparticles (NPs), which are composed of (CDs) with a targeting agent, folic acid (FA), and a chemotherapeutic agent Doxorubicin (Dox). All the NPs and their intermediates were characterized using ultraviolet-visible spectroscopy (UV-vis), fluorescence spectroscopy, and Fourier transform-infrared spectroscopy (FT-IR). The drug loading capacity (DLC) and drug loading efficiency (DLE) of two series of FA-CDs-Dox were assessed using UV-vis absorption spectroscopy at the wavelength of 485 nm. Both showed good DLE and DLC …

The Crucible Of History:How Apology And Reconciliation Created Modern Conceptions Of The Salem Witch Trials, Heaven Umbrell

Electronic Theses and Dissertations

For centuries, historians, authors, and amateur enthusiasts alike have been mesmerized by the Salem witch trials. Most of the literature focuses on the trials themselves and takes one of three approaches: anthropological; sociological; or conspiratorial. Recently Gretchen Adams, professor of history at Texas Tech University, approached the trials differently, focusing on memory. She narrowed on how the “specters of Salem” loomed over American cultural and public memory. Apart from Adams, little scholarly inquiry has focused on the aftermath of the trials, especially how it affected the people directly involved. This thesis will expand the historiography of the Salem witch hunt …

Implicit Memory And Online Advertisement Priming, Matthew L. Custard

Electronic Theses and Dissertations

Implicit Memory research has been investigating the attentional requirements needed for something to be encoded and accessible through implicit memory. So far, previous research has produced mixed results on attentional requirements for perceptual implicit memory, some studies citing evidence for the need of attention, others citing the opposite. As well, research has been consistent in producing results showing that conceptual implicit memory has higher attentional demands than that of its perceptual counterpart. Adopting Transfer-Appropriate Processing framework, the current paper investigates attention requirements for both a perceptual task (picture identification) and a conceptual task (category exemplar generation). Participants examine webpages with …

Investigating Administrators’ Resistance To Implementing Restorative Practices, Beri Deister

Electronic Theses and Dissertations

In this case study, the researcher investigated the barriers to school administrators’ implementation of restorative practices as a management approach to student behavior. Based on the claim that restorative practices is a promising alternative to exclusionary disciplinary placements for changing behavior, the researcher used an emergent explanatory mixed methods design to better understand administrators’ resistance to change despite overwhelming evidence that exclusionary disciplinary practices are the primary contributors to national trends in disciplinary disproportionality and institutional discrimination. The researcher identified and analyzed barriers to create recommendations for addressing administrators’ resistance through organizational change strategies using systems theory.

A Power Man’S Theology: Marvel’S Luke Cage And Black Liberation Theology, Diarron B. Morrison

Electronic Theses and Dissertations

Netflix released Marvel’s Luke Cage in 2016 to critical acclaim. Born from a 1970s comic book, the series features Luke Cage, an African-American superhero. Cage is a big, bald, bulletproof black man. Instead of tights and a cape, Cage wears a hoodie calling the audience to remember Trayvon Martin and other victims of white racism. Theologian James Cone created Black Liberation Theology in the 1970s. As a result of Cone’s work, Black Liberation Theology addresses the issue of white racism from a theological standpoint. In this thesis I present a close reading of Marvel’s Luke Cage using Black Liberation Theology …

The researcher limited the study to the role of the campus principal and used purposive sampling to select participants from 3 diverse districts in the state of Texas. Because there may be discrepancies between leaders’ perceptions and behaviors, the researcher conducted interview sessions with principals and principal supervisors and conducted observation sessions in principals’ natural work environments. The study results showed that good …

Local Anesthesia Before Intravenous Cannula Insertion: Recommendations For Registered Nurses In Practice, Vera Campbell-Jones

Electronic Theses and Dissertations

Abstract

Administering local anesthetics, such as intradermal, should become standard practice for RNs in pretreatments for pain control prior to intravenous insertion. Peripheral venous cannulation has provoked the most fear and anxiety in adult patients about everyday practice in hospitals. Adult patients often state that this procedure causes considerable discomfort. Local anesthesia for cannulation is usually not offered to adult patients who are on general medical units. Evidence has indicated inconsistency in the use of pain management strategies during these procedures. The researcher’s goal in this project was to educate RNs about the intradermal pretreatment procedure, provide education on the …

Conspiracy Theories And The Quest For Truth, Rachel Runnels

Electronic Theses and Dissertations

Conspiracy theories are deeply embedded in American culture, especially in current American society. The popularity of conspiracy theories in general reveals that society is becoming increasingly skeptical of authoritative organizations. Because of “fake news” and the availability of information and connection on the internet, people feel as though they must question everything, even sources they previously viewed as unquestionable authorities.

My analysis looks at how online conspiracy organizations create and defend their arguments in an attempt to understand why conspiracy theories are so persuasive. I analyze the rhetoric of three online conspiracy theory organizations: the Flat Earth Society, the Mutual …

Worship-Worthiness And Absolute Perfection: Towards An Account Of Supreme Worship-Worthiness, Austin Mccoy

Electronic Theses and Dissertations

Theists and non-theists alike have generally taken absolute perfection to be a necessary condition for worship-worthiness. Unless the object is absolutely perfect, it is often put, the kinds of attitudes or actions constitutive of worship are unwarranted. In this thesis, I offer an account of worship-worthiness that does not take for granted that to be worship-worthy is to be absolutely perfect. More specifically, I advance the claim that to be absolutely perfect is to be supremely worship-worthy and that supreme worship-worthiness holds a unique position in this respect. For instance, I argue that to be absolutely perfect and thus supremely …

Using Behavior Economic Nudges To Facilitate Client Follow-Through In Financial Coaching, Charlene Hurst

Electronic Theses and Dissertations

While benevolence-based programs have been a large part of meeting immediate financial needs of the poor, they lack the relational aspect needed to facilitate long-term behavior change. Recently many social service organizations have adopted financial coaching as a promising replacement for benevolence programming. The field of coaching has dealt with its own challenges. Most coaching practitioners surveyed in 2016 and 2019 acknowledged lack of client follow-through as their number one challenge. Behavior economics offered nudges as a solution. Nudges are cues placed within the physical environment to prod clients toward behavior change. A quantitative field study was conducted to evaluate …

The Sound Of Adventure: Two Original Compositions That Combine Music, Sound Design, And Post-Production, Inspired By Outdoor Experiences, Jason K. Gibson

Electronic Theses and Dissertations

Composers have been inspired by nature for centuries, but writing music about nature is becoming more popular in our day. Now, under titles like “Landscape Music” and “Environmental Music,” many composers seek to embody the feeling of nature in music. What has yet to be fully developed is how electronic music and landscape music can overlap in the chamber music world. This project culminates in two original compositions, Natural Opposition (ca. six min), and Giants at Night (ca. 15 min), that seek to satisfy the requirements of both realms by combining naturally inspired music with electronic influences. The compositions themselves …

.Pause., Richelle M. Dorris

Electronic Theses and Dissertations

.Pause. is a series of fifteen abstract oil paintings that represent a visual inspection of changing mental/emotional states of being as we navigate life. My subject matter consists of natural and organic forms that twist, contort, overlap, and flow. These aspects—combined with dramatic and gradual shifts in color, movement, layering and lighting—create a bizarre environment of conflict and growth as well as a space for contemplation.

This series is a mixture of stylistic directions, including abstract representation, gestural, and nonobjective work. Perception is called into question as the visual information becomes more obscure. Outside elements, such as lighting and the …

Visitor Characteristics, Attitudes, And Management Preferences Of The Bob Marshall Wilderness Complex, Samuel J. Rhodes

Here visitors can find a plethora of recreation opportunity that give access to some of the most rugged country that can be found in the lower 48 states. However, managing wilderness areas comes with the challenge of both preserving the natural resources found within their borders and enabling opportunities for recreational experiences. Wilderness social scientists always have striven to determine the type of visitors coming to wilderness, and see what sorts of experiences they pursue. …

The Potential Of Radium-224 As A Tracer Of Timescales Of Gulf Of Mexico Crude Oil Exposure To The Marine Environment, Matthew T. Kurpiel

Electronic Theses and Dissertations

Petroleum pollution in the marine environment can be deleterious to coastal and marine ecosystems and can have sustained effects for years. While oil slicks on the surface of the ocean are tracked with relative ease using satellite-based technology, deep sea, neutrally-buoyant hydrocarbon plumes remain exceedingly difficult to track. We provide evidence for the utility of Ra-224 as a potential hydrocarbon tracer to determine the marine exposure time of crude oil. We employed time course incubations to constrain a time dependent Ra-224 release signature and tested a variety of timescales, temporal resolutions, oil sources, seawater, and experimental treatments to determine potential …

A Kinetic And Thermodynamic Model Of Ethylene Dichloride Pyrolysis., Travis J Czechorski

Electronic Theses and Dissertations

Ethylene dichloride (EDC) is a precursor for the production of vinyl chloride (VCM) which is subsequently polymerized to form polyvinyl chloride (PVC). To convert EDC to VCM, EDC undergoes a pyrolysis process in the absence of oxygen at temperatures exceeding 500C. However, process yields are limited by the uncontrolled production of side-products that can degrade the quality of PVC and poison the reactor. Thus, tight process controls and costly separations guided by heuristics and plant operator experience are used to optimize EDC pyrolysis. To improve the process, I have programed a kinetic model of EDC pyrolysis based upon estimations of …
