A Metamorphosis Of Thought: Parent Education Based On Transformative Learning Theory In A Title I-Funded Middle School, Ayanna Lichelle Shivers
Dissertations
Section 1118(e)(2) of the No Child Left Behind Act of 2001 encouraged public schools to conduct and evaluate parent education programs to assist with closing the achievement gap. In an effort to combat the existing problem, the researcher engaged in a mixed-methods study to address four research questions.
A comparative-quantitative study, using the Middle School Parent Perception Survey, was conducted to determine if there were statistically significant differences in perceptions of parents whose children attended Title I funded and non-Title l-funded schools in the following areas—barriers to parent involvement, their ability to assist their children with schoolwork, and the support …

Intergenerational Communication: Its Effect On Early Screening Activities In African-American Adult Daughters Of Mothers With Breast Cancer, Rita R. Callahan Phd, Ma, Bsn, Rn
Dissertations
Health communication at numerous levels is vital to sustainability of healthy individuals. The notion of African-American mothers and adult daughters sharing breast health and breast cancer knowledge openly and honestly could be the initial step in addressing the high morbidity and mortality that continues to affect this population. Communication is a variable that has yet to be studied between African-American mothers diagnosed with breast cancer and their adult daughters. This study first examined whether this relationship existed, and secondly if it was strong enough in supporting and encouraging one another towards consistent breast health and breast cancer screening activities. The …
Roots Of Ancient Wisdom For Contemporary Education, Patricia Ottow Keen Edd
Roots Of Ancient Wisdom For Contemporary Education, Patricia Ottow Keen Edd
Dissertations
Scholars have long contended that the main purpose of education is to guide youth towards more authentic, fruitful ways of being in the world; this ancient wisdom continues to challenge educators to serve as effective role models (e.g., Aristotle, 1963; 1985; Maslow, 1993; Palmer, 1998). Yet, until now, teachers' levels of self-actualization have not been investigated with valid and reliable instruments. This quantitative study used two psychometrically sound, closed-ended surveys to investigate the extent to which teachers consider themselves self-actualized and mindful; it measured the direction and strength of the correlation between their self-actualization and mindfulness scores; and, investigated the …
Increasing Narrative Coherence In The Bereaved: The Effect Of Narrative Review On Grief Reaction, Stefanie Suzon Boswell
Increasing Narrative Coherence In The Bereaved: The Effect Of Narrative Review On Grief Reaction, Stefanie Suzon Boswell
Dissertations
In order to investigate the utility of an experimental expressive writing intervention designed to increase narrative coherence (write about loss combined with review of previous narratives) as a potential bereavement intervention, it was compared to a standard expressive writing intervention (write about loss with no opportunity for review), and two trivial writing conditions (one with and one without opportunity for review). Although all writing groups experienced beneficial effects across time, participants in the experimental and standard conditions reported significantly greater personal growth as a function of time when compared to control participants.

The Use Of Personality Assessments In Designing Environmental Enrichment For Garnett's Bushbabies (Otolemur Garnettii), Lauren Elizabeth Highfill
Dissertations
Recently the study of animal personality has become an important and credible topic of research and a number of studies have revealed personality traits in a variety of species. The consideration of individual animal personality traits is important for animal management and welfare. For example, ensuring inter-individual compatibility in group housing animals may serve to ensure the safety of the whole group. To date, no formal research has been conducted on whether the assessment of individual personality traits could be used as a tool for individualizing environmental enrichment interventions. The goal of environmental enrichment is to increase the rate of …

Treatment Of A Wife's Body In The Fiction Of Indian Sub-Continental Muslim Women Writers, Hafiza Nilofar Khan
Dissertations
Ismat Chughtai of India, Tehmina Durrani of Pakistan, and Selina Hossain of Bangladesh depict some of the sociological, religious and legal aspects of wife abuse that is a chronic, yet little discussed anathema in a Sub-Continental Muslim wife's life. "Treatment of the Wife's Body in the Fiction of Indian Sub-Continental Muslim Women Writers," examines the fiction and autobiographical works of these women writers who problematize the deeply ingrained traditional modes of domestic violence as perpetuated upon the minds and bodies of Sub-Continental Muslim wives. Chughtai, Hossain and Durrani identify culture specific practices such as child marriage, dowry, polygamy, honor crimes, …
Identification Of Two Distinct Glutaminyl Cyclase Isoforms In Drosophila Melanogaster, Amanda Thigpen Parker
Identification Of Two Distinct Glutaminyl Cyclase Isoforms In Drosophila Melanogaster, Amanda Thigpen Parker
Dissertations
Sequence analyses revealed two putative glutaminyl cyclase genes in Drosophila melanogaster with greater than 60% amino acid sequence identity to previously identified glutaminyl cyclase in humans. Expression, purification, and characterization of both putative proteins revealed two enzymatically active glutaminyl cyclase enzymes. Comparison of the Drosophila melanogaster glutaminyl cyclase enzymes to the published human glutaminyl cyclase revealed the enzymes were very similar. The Km values obtained were identical to those of human glutaminyl cyclase for three different substrates tested. However, the Drosophila glutaminyl cyclases demonstrated lower turnover numbers. Both Drosophila glutaminyl cyclase isoforms were inhibited by imidazole, imidazole derivatives, and metal …

Combined Cognitive Behavioral Treatment Plus Caregiver Sessions For Childhood Depression, Dikla Eckshtain
Combined Cognitive Behavioral Treatment Plus Caregiver Sessions For Childhood Depression, Dikla Eckshtain
Dissertations
Childhood depression is intimately related to the family context and caregiver-child relations, but only a limited number of treatment outcome studies for depressed youth have formally included members of the family in the intervention. To address this discrepancy the present study evaluated the efficacy of adding caregiver sessions to individual cognitive behavioral therapy (CBT) for the treatment of depressed youth. The treatment included 16 individual sessions and 7 caregiver sessions administered in the child's school to promote accessibility. Fifteen children (10 females and 5 males ranging in age from 8-13), who met inclusion criteria based on self-report and interview measures …
Emotion Recognition And The Propensity To Engage In Sexually Coercive Behaviors: A Study With College Males, Beth J. Dietzel
Emotion Recognition And The Propensity To Engage In Sexually Coercive Behaviors: A Study With College Males, Beth J. Dietzel
Dissertations
Several variables have been investigated over the past years as risk factors for sexual aggression. Among them, substance use/abuse, family environment, attitudes towards women, and lack of empathy. Although researchers have identified several risk factors, predicting aggressive behaviors continues to be a difficult task. One variable that has received less attention in the literature is men's emotion recognition skills. Do men's emotion recognition skills affect their propensity to aggress?
The purpose of this study was to investigate emotion recognition skills/deficits and how such skills predict propensity to engage in sexually coercive behavior. There were two main goals of this study. …
The Theory And Practice Of Drug Courts: Wolves In Sheep Clothing?, Kristen E. Devall
The Theory And Practice Of Drug Courts: Wolves In Sheep Clothing?, Kristen E. Devall
Dissertations
This dissertation is a case study of an adult drug court in a medium-size Midwestern city. The primary impetus behind the creation of the drug court model was the partial recognition that the "get tough" approach to crime and the "war on drugs" was ineffective in "solving the United States' drug problem. Drug courts represent an integration of a public-health approach and a public-safety strategy of fighting crime and administering "justice." The bulk of the extant research regarding drug courts addresses one central question: "Do drug courts work?" Researchers and evaluators alike have attempted to answer this question over the …

Exploring The Cognitive Underpinnings Of Word Retrieval Deficits In Dyslexia Using The Tip-Of-The-Tongue Paradigm, Sarah Margaret Hanly
Exploring The Cognitive Underpinnings Of Word Retrieval Deficits In Dyslexia Using The Tip-Of-The-Tongue Paradigm, Sarah Margaret Hanly
Dissertations
Over the past thirty years a consensus has emerged that the word reading difficulties of dyslexic readers stem from deficits in phonological processing. One experimental paradigm that has provided support for this view is the finding that dyslexic readers demonstrate deficits in word retrieval from long term memory on picture naming tasks. Dyslexic readers are able to retrieve fewer words in their receptive vocabularies and are less accurate than normally developing readers. However, the conclusion that dyslexic readers? difficulties in picture naming are the consequence of deficits in phonological processing is inferential. The current study uses the tip-of-the-tongue (TOT) paradigm …

The Impact Of Gender Socialization On Women?S Learned Technological Helplessness And Its Andragogical Implications, Joy Elise Harris
Dissertations
This research investigated a proposed construct of learned technological helplessness (LTH) in female adult learners, which is believed to be impacted by socialization into traditional gender roles, teacher modeling, and age. A two-pronged approach was used to examine women?s attitudes and beliefs about their abilities to use technology as a learning and personal productivity tool. Participants were females, over age 18, on two campuses of a public Midwest research university. Prior to the primary research, a pilot study (n=204) was undertaken for the purpose of creating a teacher modeling instrument, which measured how teachers model the use of technology. The …
Does Institutional Capacity Matter? A Case Study Of The Zambian Forestry Department., Rosemary Fumpa Makano
Does Institutional Capacity Matter? A Case Study Of The Zambian Forestry Department., Rosemary Fumpa Makano
Dissertations
Understanding why some organizations are more effective in their service delivery than others is a central discourse in both public administration and political organization. Scholars and practitioners all agree that the defining factor is institutional (state) capacity. Since the mid-1980s, deforestation in Zambia has been on the rise, especially in Protected Forest Areas, suggesting poor management by the Forestry Department, an institution mandated to manage these public lands. Ironically, despite the strategic position that forests hold in sustaining both the daily subsistence needs of over 90% of the Zambian population as well as the as the numerous industries that depend …
Systematics And Floral Evolution In The Plant Genus Garcinia (Clusiaceae), Patrick Wayne Sweeney
Systematics And Floral Evolution In The Plant Genus Garcinia (Clusiaceae), Patrick Wayne Sweeney
Dissertations
The pantropical genus Garcinia (Clusiaceae), a group comprised of more than 250 species of dioecious, trees and shrubs, is a common component of lowland tropical forests and is best known by the highly prized fruit of mangosteen (G. mangostana). The genus exhibits as extreme diversity of floral form as is found anywhere in angiosperms and there are many unresolved taxonomic issues surrounding the genus. To understand patterns of floral evolution within the group and to evaluate morphology-based classification schemes involving Garcinia and its relatives, relationships among a broad sample of Garcinia and close relatives were inferred by conducting Bayesian, parsimony, …

Community Ecology And Phylogeography Of Bird Assemblages In Arid Zones Of Northern Venezuela: Implications For The Conservation Of Restricted-Range Birds, Adriana Rodriguez-Ferraro
Dissertations
Aridlands of northern Venezuela are important from an ornithological perspective because of the occurrence of habitat specialist birds that depend exclusively on desert scrubs and are endemic to this region. Currently, long-term survival of habitat specialists is threatened by ongoing changes in vegetation but the effects of such changes on bird assemblages are unknown. The goal of this study was to characterize bird assemblages found in six arid zones in northern Venezuela at both ecological and genetic levels, and to generate information relevant for conservation planning. The study involved assessments of patterns of avian species richness, abundance, community composition and …
Sex Offender Assessment: Clinical Utility And Predictive Validity, Kristopher Lueron Clounch
Sex Offender Assessment: Clinical Utility And Predictive Validity, Kristopher Lueron Clounch
Dissertations
The research addressing sex offender assessment and treatment is an ever-evolving science. However, very little research has addressed psychological typologies associated with various types of sex offenders and treatment engagement. The current study examined assessment data of four sex offender groups, defined by victim type, to determine if a typological difference exists between groups of (N = 583) rapists (n = 129), statutory offenders (n = 140), intrafamilial/ incest perpetrators (n = 152), and extrafamilial (n = 162). Secondly, the study determined if a specific battery of psychological measures can predict treatment completion (n = 377). We also hypothesized there …

Towards Development Of A Fully Synthetic Conjugate Vaccine: Investigation Of Structural Analogs Of Streptococcus Pneumoniae Serogroup 6, Archana R. Parameswar
Dissertations
Involvement of complex glycostructures in a variety of damaging and healing processes has already been acknowledged by development of carbohydrate-based vaccines and therapeutics. The bacteria Streptococcus pneumoniae (SPn) have become one of the most frequent causes of pneumonia, bacteremia, and meningitis in the elderly, immunocompromised, and, especially, in young children. SPn has one of the largest public health and economic impacts amongst all bacterial infectious diseases. Over 2 million children die annually worldwide due to pneumonia, accounting for almost 20% of deaths under age five with more than half of these deaths attributed to SPn. Amongst over ninety elucidated SPn …

Synthesis Of Α-Hydroxy And Fluoro Phosphonates And Cyclic Ether-Containing Natural Products, Nongnuch Sutivisedsak
Dissertations
A number of important classes of natural product (eg. amphidinolide C, (-)-centrolobine, etc) contain common structural features of tetrahydrofurans and tetrahydropyrans. This study involved the development of stereoselective mothods for the synthesis of tetrahydrofurans and tetrahydropyrans including the application of allylic hydroxy phosphonates and their derivatives as chiral, non racemic building blocks for the synthesis of biological active molecules. The enantiomeric excess of non racemic α-hydroxy phosphonates and carbonate derivatives prepared via the asymmetric Pudovik reaction can be improved by kinetic resolution. Both chemical and enzyme catalysts were utilized in the kinetic resolution of phosphonates. Enantioselective acylation of a variety …
Spatial And Temporal Dynamics Of Lekking Behavior And Female Mate Choice In The Blue-Crowned Manakin (Lepidothrix Coronata, Aves: Pipridae), Renata Duraes Ribeiro
Spatial And Temporal Dynamics Of Lekking Behavior And Female Mate Choice In The Blue-Crowned Manakin (Lepidothrix Coronata, Aves: Pipridae), Renata Duraes Ribeiro
Dissertations
In lekking species, males aggregate at display grounds (?leks?) that females visit to copulate. Lekking systems are non-resource-based and males vary widely in reproductive output. This dissertation investigates how spatial and temporal factors influence lekking dynamics and female mate choice in the blue-crowned manakin Lepidothrix coronata. The first chapter deals with spatial dynamics of lekking behavior, and investigates whether leks are formed by the establishment of males on sites of high female density (?hotspot hypothesis?). Predictive maps of female spatial distribution were built based on field data and contrasted to the lek distribution. Leks were located in sites where males …

A Developmental, Phylogenetic And Taxonomic Study On The Moss Genus Taxithelium Mitt. (Pylaisiadelphaceae), Paulo Saraiva Camara
Dissertations
The family Sematophyllaceae is probably the most diverse Hypnales in the tropics and one of the most complex and taxonomically confused. This thesis comprises three parts: 1, a micromorphological study of papilla development in Taxithelium and relatives; 2, a phylogenetic study of Taxithelium; and 3, a revision of Taxithelium subgenus Vernieri. 1. I present data on the structure and development of leaf cell papillae in different Sematophyllaceae. Two kinds of papillae are recognized. One is dome-shaped to conical tapering to a firmly rounded apex (?conical?), whereas the other presents a more flaccid, baggy appearance, and is often flat-topped and wider …
Population Genetics Of Island Endemics: Neutral And Major Histocompatibility Loci, Jennifer Lynn Bollmer
Population Genetics Of Island Endemics: Neutral And Major Histocompatibility Loci, Jennifer Lynn Bollmer
Dissertations
Island archipelagoes are ideal for the study of microevolutionary forces due to their multiple, closely related but geographically disjunct populations. I used both neutral and major histocompatibility complex (MHC) loci to determine the population genetic structures of bird species endemic to the Galapagos Islands. MHC molecules recognize foreign pathogens in the body, and these loci are known for their high degree of genetic variability maintained by natural selection. Small island populations are predicted to have reduced genetic variability due to the effects of genetic drift; however, selection may be strong enough to prevent the loss of variability at MHC loci. …
Mechanistic Studies Of Specific Dna Cleavage By Pvuii Restriction Endonuclease, Xie Fuqian
Mechanistic Studies Of Specific Dna Cleavage By Pvuii Restriction Endonuclease, Xie Fuqian
Dissertations
PvuII restriction endonuclease is a homodimeric protein which recognizes and cleaves the palindromic sequence (CAG?CTG) in the presence of Mg(II) ions. Starting with PvuII as a model system, pKa calculations with crystallographically defined metal ligated water are applied to PD?D/ExK motif metallonucleases in order to investigate the activation of nucleophile in metal dependent DNA hydrolysis. These results establish the electrostatic contributions of the metal ions and the conserved Lys in lowering water pKa. The calculated pKa values of metal ligands have been used to simulate the pH dependence of Mg(II) binding to PvuII. The bell shaped pH-rate profile is dissected …
Reproductive And Social Dynamics Of A Lek Breeding Bird, Thomas Brandt Ryder
Reproductive And Social Dynamics Of A Lek Breeding Bird, Thomas Brandt Ryder
Dissertations
Sociality and the unequal apportionment of reproductive success among social individuals is a common characteristic of many vertebrate taxa. To date, our understanding of what factors drive high variance in reproductive success (i.e., intra vs. inter-sexual selection) and which male attributes contribute to that variance, are still fragmentary for most species. Moreover, how social structure interacts with individual behavior and fitness remains understudied despite its potential importance to the evolution of cooperation. This dissertation research focused on understanding this complex synergistic interplay between social and reproductive dynamics in a lek-breeding bird, the wire-tailed manakin. The first chapter examines the complex …
Mindfulness In Childbirth: An Investigation Of The Effects Of Mindfulness Training On Maternal Satisfaction With Childbirth And Obstetric Outcomes, Brenda L. Bratton
Mindfulness In Childbirth: An Investigation Of The Effects Of Mindfulness Training On Maternal Satisfaction With Childbirth And Obstetric Outcomes, Brenda L. Bratton
Dissertations
This study investigated the effects of mindfulness training on obstetric outcomes and maternal satisfaction with childbirth. We were interested in whether mindfulness training was more effective than a control group receiving psychoeducation on stress reduction. The goal of the intervention group was to increase participants' moment-to-moment awareness of thoughts, feelings, and body sensations during childbirth so that they would respond to these experiences rather than react to them in an automatic manner. These strategies were hypothesized to help a laboring woman minimize fear or anxiety associated with pain and complications and be more adaptive to whatever circumstances arose. Repeated measures …
