Culturally Relevant Education For Rural Schools: Creating Relevancy In Rural America, Joshua J. Anderson

Dissertations

In this dissertation, I investigate the ways in which culturally relevant pedagogy is conceptualized and implemented by two secondary English Language Arts educators in one school district with a strong sense of rural identity. Culturally relevant pedagogy is considered by many professionals in the field of education to be an effective philosophy to inform instructional practices for narrowing the achievement gap of historically marginalized groups (Cummins, 1990; Gay, 2000; Ladson-Billings, 1994, 2000). A careful review of the literature on culturally relevant pedagogy reveals the discourse surrounding culturally relevant pedagogy has largely been dominated by urban voices (Cochran-Smith, 2003; Esposito & …

Natural Disasters In Latin America: The Role Of Disaster Type And Productive Sector On The Urban-Rural Income Gap And Rural To Urban Migration, Madeline Alice Messick

Dissertations

This research provides insight into the impact of natural disasters as drivers of rural to urban migration in Latin America and the Caribbean (LAC). Disasters of varying types are predicted to have differing impacts on the productive sectors of agriculture, industry, and services; which due to the concentration of the various productive sectors in either urban or rural areas, subsequently changes the urban-rural wage differential. Changes to the wage differential (as measured by the urban-rural income gap) are predicted to lead to movement between urban and rural areas until a new equilibrium wage is reached.

This dissertation first identifies a …

Emotion-Related Factors As Mediators In The Relation Between Family Stress And Adolescent Externalizing Problems, Kristy Marie Disabatino

Dissertations

Adaptive regulation of emotions, maternal depression, parenting stress, and environmental stress have all been related to adolescent psychosocial outcomes. Considering these established relations, the current study examined serial mediation models in which it was hypothesized that (1) maternal distress or community stress (examined in separate models) would positively relate to adolescent externalizing behaviors directly and (a) indirectly through maladaptive maternal emotion socialization (ES) practices (i.e., magnify, neglect, and punish), (b) indirectly through adolescent emotion regulation (ER) difficulties, and (c) indirectly through both maternal ES practices and adolescent ER difficulties; (2) maternal distress or community stress would positively relate to adolescent …

A Library Of Coumarin-Enaminone Chemodosimeters For The Detection Of Analytes, Aaron Berrell Davis

Dissertations

Many anions and metal ions are of biological and environmental importance. This work describes our attempts to synthesize molecular probes to specifically target cyanide, zinc, cadmium and mercury as these species can often result in negative effects to the environment and the human body.

The work in this dissertation, describes the synthesis of a family of coumarin-enamine chemodosimeters, in a straightforward synthetic procedure, the reaction between 7-(diethylamino)-4-hydroxycoumarin and a primary amine. The work presented in this dissertation demonstrates that these molecules can play dual roles and therefore the work is split into two distinct parts: Part 1 describes one role …

The Synthesis Of Chemosensors For Toxic Analytes, Johnathan Hugh Broome

Dissertations

A number of chemosensors have been designed and synthesized to target cations (Zn²⁺ions), neutral molecules (cathinones), charged molecules (aminoindanes), and anions. The Zn²⁺ ion sensor featured bistriazole designed binding unit and ferrocene signaling units. Characterization of Zn²⁺ ion binding was carried out with electrochemical techniques (CV and DPV), ¹H-NMR, mass spectrometry, and molecular modelling. It exhibited a 1:1 binding stoichiometry with Zn²⁺ and had an affinity for ZnCl₂ (Log K_1:1 = 4.1 ± 0.02) over other Zn²⁺ salts.

The cathinone probe was designed to selectively bind mephedrone over common street drugs …

Predictors Of Alcohol Consumption, Use Of Protective Behavioral Strategies, And Alcohol-Related Sexual Consequences: A Gendered Social Learning Perspective, Kayla Darlene Moorer

Dissertations

Given the long standing gender differences in regard to alcohol-related behaviors and consequences, understanding how conformity to gender norms may predict alcohol-related outcomes is an important next step in developing effective prevention efforts aimed at reducing alcohol-related sexual consequences for college women. The current study examined the relationships among conformity to feminine and masculine gender norms and alcohol-related outcomes (harmful drinking patterns, protective behavior strategy use, and sex-related consequences) among college women. Another primary aim of the study was to determine the extent to which sex-specific alcohol expectancies mediated the associations between gender norms and alcohol-related outcomes. Participants were 421 …

Profiles Of Academic Commitment, Anna Jill Womack

Dissertations

Tinto (1993) found that only 15-25% of students who dropped out of college did so due to academic failure, while the reasons for leaving among the remaining group of students who dropped out were unknown. This suggests that the majority of students who drop out of college are likely doing so for reasons other than academic struggles. Researchers have suggested that individuals who are committed to their major are more likely to obtain a bachelor’s degree (Bowling, Beehr, & Lepisto, 2006; Den Hartog & Belschak, 2007; Duffy, Dik, & Steger, 2011; Goulet & Singh, 2002; Landrum & Mulcock, 2007), indicating …

Ecological And Phenotypic Factors Influencing The Movement Dynamics Of The Blackspotted Topminnow, Fundulus Olivaceus, Scott Richard Clark

Dissertations

Movement of individuals throughout a landscape is a complex behavior that has important consequences on numerous ecological and evolutionary processes. Perhaps most notably is the relationship between movement and reproduction, as this has implicit ramifications on individual fitness and consequently, population level processes. Although this relationship has been theoretically and empirically demonstrated across a number of animal taxa, its role in fishes remains understudied and largely unknown. Using a series of outdoor mesocosms, in combination with a field study, I employed passive integrated transponder (PIT) tags to experimentally assess the sex-specific movement dynamics of a small-bodied, sexually-dimorphic stream fish, the …

The Role Of Parental Locus Of Control In The Relations Among Early Childhood Temperament, Parenting Practices, And Child Externalizing Behavior, Amanda Kathryn Stary

Dissertations

Child externalizing behaviors are a common reason for children’s referral for mental health services, and parenting practices are a primary target of efficacious interventions. In turn, child temperament and parent beliefs, such as parental self-efficacy and locus of control, relate to use of specific parenting practices. The present study aimed to evaluate whether parental locus of control and related components moderate the indirect effect of preschool-aged children’s temperament on their externalizing behaviors through parenting practices. Specifically, child temperament was expected to predict parenting practices only at certain levels of locus of control. Female caregivers of 146 children ages 3-5 years …

The Effect Of Auditory Stimulation On Sleep Disruption In West Indian Manatee (Trichechus Manatus Latirostris), Natalija Lace

Dissertations

Florida manatees inhabit waterways where motorized boats are common. Although manatee mortalities resulting from boat strikes are well documented, the effect of boat noise on some manatee behaviors, including rest, has not been investigated. This study focuses on rest behavior and used a playback experiment with four manatees at the Lowry Park Zoo in Florida. We tested their responses to playback stimuli of either boat noise, silence, or manatee calls. A playback trial was initiated when the focal animal showed behavioral characteristics of rest.

Results showed that rest was interrupted in response to the playback of boat noise for each …

Preparation And Characterization Of Singlet-Oxygen Generating Thiol-Ene Networks Containing Fullerene And Metallofullerene Derivatives, Emily Matthews Barker

Dissertations

This work explores the derivatization of C₆₀ and Sc₃N@C₈₀ with S-, P-, and C- centered radicals, and is the first exploration into the functionalization of Sc₃N@C₈₀ with sulfur and phosphorous. The number of addends bound to C₆₀, as a function of reaction time and molar ratios, as well as, structure-property relationships including thermal stability, solubility, and singlet oxygen generation were explored. Fullerene derivatives exhibiting enhanced solubility were incorporated into two different thiol-ene polymer matrices at varying thiol-ene monomer concentrations (1:1 or 1:0.75 molar equivalents) and at different C₆₀ loadings (0, …

A Statistically Significant Determination From Pretest To Posttest In Knowledge Of Electrophoresis Concepts, Parker Megehee Nelson

Dissertations

The statistical significance from pretest to posttest of 109 high students constructing an electrophoresis chamber or not was explored. The students tested were from six intact biology classrooms. Three classes were treatment groups and three were control groups. The three biology teachers each taught a control and treatment group classroom. Except for building the electrophoresis chamber, students in both groups received identical instruction and testing. Pre- and posttest data was examined by means of a content valid test constructed by the researcher and biology teachers. In order to examine the statistical significance from pretest to posttest in knowledge of electrophoresis …

Analysis Of The Intricacies Of Substrate Recognition Of High Mobility Group Proteins And Aminoacyl-Trna Synthetases Using Non-Cognate Substrates, Douglas Van Iverson Ii

Dissertations

The studies presented in section 1 (Chapters I-IV) focus on the design and development of nucleic acid four-way junctions (4WJs) to target a member of the high mobility group (HMG) proteins, the proinflammatory cytokine high mobility group box 1 protein (HMGB1). In the present study, hybrid PNA-DNA 4WJs based on a model DNA 4WJ were constructed to improve the thermal stability of 4WJs while maintaining strong binding affinity toward HMGB1. An electrophoretic mobility shift assay (EMSA) was used to examine the binding affinity of an isolated DNA binding domain of HMGB1, the HMGB1 b-box (HMGB1b), toward a set of PNA-DNA …

Seeing Is Believing, But Is It The Truth? Reality Vs. Representation Of Men In Contemporary Magazine Advertisements, 1980-2010, Dana Ann Lopez Coleman

Dissertations

McQuail (1994) observed, “The entire study of mass communication is based onthe premise that the media have significant effects” (p. 327). Many of these studies in mass communication have focused specifically on the various consequences that are believed to be a result of advertising. These images and perceptions can also become an individual’s reality which serves to shape society and their day-to-day environment. As Rudy, Popova, and Linz (2010) wrote, “Extensive media exposure leads audience members to adopt media reality as their own, and these altered conceptions of reality can in turn influence behavior” (p. 708). Understanding these visual representations, …

The Effect Of Stereoscopic Three-Dimensional Images On Recall Of Second Language Vocabulary, Regina Kaplan-Rakowski

Dissertations

The purpose of this experimental study was to investigate the effect of stereoscopic three-dimensional (S3D) images on productive and receptive recall of foreign language vocabulary. S3D images are highly-realistic and differ from non-stereoscopic three-dimensional (NS3D) images in that they provide the impression of the added third dimension of depth. This within-subject study exposed the participants (N = 82) in a controlled setting to a series of carefully designed and randomly distributed NS3D and S3D images. The subjects were then given immediate productive and receptive tests of foreign language vocabulary items that were represented by NS3D and S3D images. Quantitative data …

Women's Work: Stitching New Identity Narratives In Conflict And Post-Conflict Settings, Arielle Semmel

Dissertations

Here, I bring communication theories into conversation with peace and conflict scholarship. Specifically, I explore how the ways in which women narrate their experiences of violent conflict through sewing collectives can inform conflict transformation work. I engage in this exploration within the framework of narrative theory, using Kenneth Burke’s dramatistic pentad to analyze the narratives presented in a selection of textile pieces created by women in Chile, South Africa, and Northern Ireland. I situate this project within literature pertaining to feminist approaches to rhetoric, discussions of bridgework in identity negotiation from intercultural communication, concerns related to conflict transformation, and work …

A Quantitative Analysis Of Whether Elementary Teachers’ Science Kit Usage And Beliefs Can Predict State Science Assessment Scores, Tony E. Rice

Dissertations

The purpose of this survey was to describe and analyze the perceptions of elementary school teachers’ in a Midwestern state concerning their use of a science kit program, including to what extent a school’s state science assessment scores can be predicated from the level of science kit usage.

Prior research indicates that elementary school teachers lack the confidence in teaching science primarily because of their weak undergraduate training in inquiry-based instruction and the lack of a strong science background. Authors such as Dickerson et al. (2006) and Riggs and Enochs (2006) argued that science kits and the materials included in …

Establishing And Testing Conditioned Reinforcers: Evaluating The Effects Of The Discriminative Stimulus Procedure Using Intermittency With Individuals With Developmental Disabilities, Yannick A. Schenk

Dissertations

A common characteristic of individuals with developmental disabilities is a restricted range of interest. Developing procedures to establish new reinforcers for such individuals can promote the acquisition of new skills and ameliorate decreases in motivation related to satiation. Several procedures for conditioning reinforcers have shown to be effective in the research literature for establishing neutral stimuli as conditioned reinforcers. Most of this literature is basic research with animal subjects (e.g., rats, pigeons). Few applied studies have directly evaluated the use of these procedures. Additional research is necessary to determine their effectiveness. The purposes of this study were to: (a) evaluate …

Assessing Change In Attachment Security Of Adolescents At Residential Therapeutic Programs, Laura Santa Thum

Dissertations

Adolescents with significant, persistent behavioral and mental health problems are increasingly being treated in private residential treatment programs (RTPs). Recent research at such programs shows that adolescents’ symptoms improve over the course of treatment and that such positive results persist up to a year post discharge. This study attempts to address what is occurring below the symptom level by exploring if attachment security increases as symptoms improve over the course of treatment in private RTPs. The level of attachment security was assessed along the dimensions of attachment avoidance and anxiety as a general construct and according to specific relationships (with …

Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone And 4-Methylmethcathinone, Michael D. Berquist

Dissertations

Recent escalation in the popularity of recreational synthetic cathinone (“bath salts”) use has prompted numerous scientific investigations of the neurochemical and behavioral effects of 3,4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC), two of the more common chemical constituents of these illicit “bath salts”. Previous neurochemical and electrophysiological studies have revealed that MDPV functions as a blocker, and 4-MMC as a substrate, at monoamine transporters, and both produce transient increases in extracellular monoamines. In addition, previous research has demonstrated that MDPV and 4-MMC support self-administration in nonhuman experimental subjects, and their rewarding effects are observed when paired with contextual cues in nonhuman models …

Acceptance And Commitment Therapy For Adolescent Difficulties With Emotion Regulation: An Open Trial, Julissa A. Duenas

Dissertations

Research suggests that youth rates of mental health problems are high and that evidence-based treatments for these populations exist; however, there is a significant problem in accessibility of mental health services. Recent movements in the mental health field have shifted focus to transdiagnostic dimensions of behavior in attempt to target a broader range of psychological difficulties across larger populations. One such construct, emotion regulation, has been defined as an ability to have awareness and acceptance of emotions and control urges and impulses in order to behave towards a goal. Emotion regulation has been linked to numerous internalizing and externalizing behavioral …

Binding Properties Of Large Antiviral Polyamides (Pa1 And Pa25) And Natural Product Derivatives As Inhibitors Of Serine Hydrolases, Elena Vasilieva

Dissertations

Polyamides are a class of DNA minor groove binders that were developed from the natural product Distamycin A. PA25 (20-ring PA) showed better activity (3-fold) in the elimination of HPV16 episomes than PA1 (14-ring PA). Binding studies of PA1 and PA25 were performed in the long control region of HPV16 (7348-122 bp). PA1 showed similar binding affinity to perfect match and single mismatch binding sites. PA1 bound to double, triple, and quadruple mismatch sites with lower affinity. PA25 bound with similar binding affinity to perfect through triple mismatch binding sites. PA25 bound quadruple mismatch sites and nonspecifically. Therefore, it was …

Educators’ Perceptions Of Student Mobility During The Intermediate Elementary Grades In Two Rural Counties In Missouri, Landon S. Gray

Dissertations

Student mobility is “students moving from one school to another for reasons other than being promoted to the next school level” (Rumberger, 2002, p. 1). In this qualitative study, the researcher detailed how student mobility impacted four rural intermediate elementary schools in two select counties in southwest Missouri. Four principals, four counselors, and four classroom teachers were interviewed to learn how high student mobility impacted these participants, mobile and non-mobile students, and schools overall. There has been ample research on student mobility in the primary grades and in high school, but very little research exists dealing with intermediate elementary students. …

The Moderating Effect Of Anticipatory Grief On The Relationship Between Attachment And Perceived Closeness With Satisfaction Of Life And Marriage For Spousal Caregivers Of Individuals With Dementia, Steven C. Pote

Dissertations

With the population of individuals with dementia growing every year, spouses are frequently finding themselves in caregiving roles. The progressive nature of dementia often leads to grief over actual and expected declines in the physical and psychological functioning of those with the disease. Spouses may grieve over losses that have not yet occurred. This anticipatory grief may affect how spousal caregivers perceive their relationship. This may further affect the spouses’ satisfaction with life and marriage and impact the quality of care they provide to their loved one with dementia. Using electronic data collection through three national organizations that support caregivers, …

The purpose of this study was to explore, understand, and describe experiences of resilience by nurses in the clinical setting who demonstrate characteristics of resilience and investigate the meaning these experiences held for them. Another purpose for this study was to increase the knowledge base that nurses and nurse educators have regarding resilience including what factors contribute to the emergence and maintenance of resilience. One-on-one interviews with 14 female nurses and one male nurse who had five or more years …

Exploration Of Intergenerational Ambivalence, Parenting Practices, And The Impact On Grandparenthood Dimensions, Janae Raquel Sones

Dissertations

Changing population demographics have important implications for intergenerational relationships. While research abounds on certain family relationships, less attention has been given to the relationship between an aging parent and her or his adult child. Two theoretical constructs that have consistently been useful for examining these relationships include intergenerational ambivalence (IGA) and, to a lesser degree, dimensions of grandparenthood. Thus, the purpose of this study was to suggest new measurement strategies for these constructs, expand on the correlates of IGA and a grandparent’s perceived ambivalence regarding her or his adult child’s parenting practices, and bring new perspectives to the experience of …

Effects Of Exercise Training On Physiological And Psychological Measurements Of Cancer-Related Fatigue, Trista Manikowske

Dissertations

While exploring the differences in psychological and physiological fatigue among cancer survivors is not completely novel, the relationship between muscle function and perceptions of fatigue in cancer survivors remains mechanistically unclear. Furthermore, the effect of exercise on objectively measured muscular fatigue has yet to be studied in cancer patients. PURPOSE: To evaluate the relationship between subjective self-reported psychological fatigue measures and objectively-measured muscular fatigue in cancer survivors following a 24-week exercise intervention. METHODS: Cancer survivors were asked to complete two measures of fatigue prior to and following 12 and 24 weeks of an exercise intervention. Participants completed the revised Piper …

Unveiling Leadership Giftedness: Identifying Its Attributes And Significance For Children With Promise, Theresa Yvonne Newsom

Dissertations

Leadership giftedness continues to be the hidden dimension in gifted and talented education. There are numerous definitions, a lack of clarity for identifying leadership giftedness and an unfulfilled federal mandate for programming. Yet, leadership continues to be a hidden dimension in gifted and talented education, especially for children with promise who are sometimes identified as at-risk. With a nation’s need for the development of future leaders, this study used phenomenology to conduct interviews with eight individuals to better understand their insights and experiences with leadership as they faced and overcame adversity in their childhood or youth. By conducting open-ended interviews …

Evaluation Of The Phase Training Model Of Cancer Rehabilitation, Jessica Marlene Brown

Dissertations

Exercise is a well-established method of alleviating cancer-related toxicities during and following treatment in cancer survivors. Due to this clear evidence, exercise-based rehabilitation programs have begun to emerge. Of concern, specific recommendations of exercise prescription for patients at different time points on the cancer continuum have not been developed, and available guidelines are broad and unclear. The Phase Training Model of cancer rehabilitation was created to address this issue and replace our previously used method of exercise-based prescription and intervention. Purpose: To evaluate the effects of the Phase Training Model on cardiorespiratory endurance, muscular strength (MS), and cancer-related fatigue (CRF) …
