Associations Of Gestational Weight Gain And Breastfeeding With Postpartum Weight Change Among African American Women, Camille Schneider

All ETDs from UAB

Objective: To examine the associations of gestational weight gain (GWG) and breastfeeding (BF) with postpartum (PP) weight change among African American women. Methods: Healthy, low-income African American women (n=32) were enrolled in a prospective observational cohort study of early life origins of obesity. GWG was calculated using data retrieved from medical records. Women were stratified according to the 2009 Institute of Medicine (IOM) GWG guidelines. Investigators measured maternal body weight at 2-weeks and 3-months PP, with the difference reflecting PP weight change. BF status at 2-weeks PP was self-reported. Analysis of covariance with Bonferroni post hoc testing was used to …

The Sialyltransferase St6gal-I Promotes A Cancer Stem Cell Phenotype, Matthew Jonathan Schultz

All ETDs from UAB

Alterations in tumor cell glycosylation have been observed for decades, but the functional consequences of specific glycosyltransferase activity are not well understood. This dissertation focuses on the role of the sialyltransferase ST6Gal-I in driving ovarian and pancreatic cancer development. ST6Gal-I adds a negatively-charged sialic acid sugar in an alpha 2-6 linkage to select receptors, which can alter their function. We show that ST6Gal-I protein is upregulated in ovarian and pancreatic cancers but not expressed in normal epithelial tissue from these organs. ST6Gal-I expression in ovarian cancer correlates with decreased progression-free and overall survival, and we present evidence that ST6Gal-I expression …

The Adhd Medication Process Model: A Qualitative Investigation Of Teaching Pedagogies, Ideal Student Behavior, Labeling Processes, And Attitudes Towards Adhd Medication., Zachary Robert Simoni

All ETDs from UAB

The number of children diagnosed with and medicated for ADHD has increased within the last decades. In this study, I assert that ADHD is a serious mental health issue with a biological etiology which in many cases is alleviated by the use of medication. However, I also argue that powerful socio-cultural forces are important to understanding ADHD and medication use in the American Educational system. Physicians and psychiatrists are responsible for assigning medication as a treatment for ADHD. Nevertheless, teachers are at the front lines of the ADHD issue and handle it on a daily basis. Despite this fact, very …

Exploiting The Glioblastoma Tumor Microenvironment For Enhanced Oncolytic Herpes Simplex Virus Therapy, Tyrel Talbert Smith

All ETDs from UAB

Gliomas are the most common and fatal malignancy of the adult central nervous system. The need for new therapeutic options is clear, as standard of care therapies only extend median survival 12-14 months beyond diagnosis. Conditionally replication-competent oncolytic herpes simplex type-1 viruses (oHSV) have emerged as promising therapeutics for treating malignant gliomas. However, two factors that contribute to the dismal prognosis of malignant gliomas, immunosuppression and invasive growth, are also thought to limit virotherapeutic efficacy. We examined these factors in tumor microenvironments to explore novel strategies to treat malignant gliomas with oHSV for improved therapeutic response. In a Phase 1b …

The Tao Of Open Science For Ecology, S. E. Hampton, S. S. Anderson, S. C. Bagby, C. Gries, X. Han, E. M. Hart, M. B. Jones, W. C. Lenhardt, A. Macdonald, W. K. Michener, J. Mudge, A. Pourmokhtarian, M. P. Schildhauer, K. H. Woo, Naupaka B. Zimmerman

Biology Faculty Publications

The field of ecology is poised to take advantage of emerging technologies that facilitate the gathering, analyzing, and sharing of data, methods, and results. The concept of transparency at all stages of the research process, coupled with free and open access to data, code, and papers, constitutes “open science.” Despite the many benefits of an open approach to science, a number of barriers to entry exist that may prevent researchers from embracing openness in their own work. Here we describe several key shifts in mindset that underpin the transition to more open science. These shifts in mindset include thinking about …

Exercise At Depth Alters Bradycardia And Incidence Of Cardiac Anomalies In Deep-Diving Marine Mammals, T. M. Williams, L. A. Fuiman, T. Kendall, P. Berry, B. Richter, S. R. Noren, Nicole Thometz, M. J. Shattock, E. Farrell, A. M. Stamper, R. W. Davis

Biology Faculty Publications

Unlike their terrestrial ancestors, marine mammals routinely confront extreme physiological and physical challenges while breath-holding and pursuing prey at depth. To determine how cetaceans and pinnipeds accomplish deep-sea chases, we deployed animal-borne instruments that recorded high-resolution electrocardiograms, behaviour and flipper accelerations of bottlenose dolphins (Tursiops truncatus) and Weddell seals (Leptonychotes weddellii) diving from the surface to 4200 m. Here we report that both exercise and depth alter the bradycardia associated with the dive response, with the greatest impacts at depths inducing lung collapse. Unexpectedly, cardiac arrhythmias occurred in 473% of deep, aerobic dives, which we attribute to the interplay between …

This qualitative case study addressed the problem at a West Indies theological college that lacked the ability to provide courses for spiritual care training by using the teaching methodology of clinical pastoral education (CPE). CPE is an experiential process using a clinical method of learning to interpret human conditions. Spiritual care training through CPE teaches clerics how to help persons find meaning in life's situations and make connections with their God. Guided by the frameworks of transformative learning and critical theological reflection, this study explored the lived experiences of 5 purposefully selected CPE students who participated in 1 unit of …

Screening And Intervention For Women With Hyperglycemia During Pregnancy, Ladonna Lynn Williams

Walden Dissertations and Doctoral Studies

Gestational diabetes mellitus occurs in up to 10% of pregnancies and often leads to labor and delivery complications for both the mother and the baby. Early identification of gestational diabetes and educational intervention are needed to improve the self-management and knowledge among pregnant women. The purpose of the project was to implement newly established national guidelines to ensure that women with gestational diabetes are identified during the first trimester of pregnancy and begin diabetes education early in gestation. Lewin's planned change theory was selected as the theoretical framework, and the six sigma approach was used to facilitate the change process. …

A Case Study Of A University's Remedial Program For Passing The Praxis I, Tassi Fite Brinkley

Walden Dissertations and Doctoral Studies

Underprepared students desiring to enter teacher education programs struggle to achieve minimum state-required Praxis I exam scores. This problem affects teacher education programs, student success, and university enrollment and retention. With proper resources and support, these students may experience personal and academic success that may be transferred to their own students once they are certified teachers. At the participating mid-South university, the effectiveness of the existing remedial program was unknown. The study's purpose, rooted in the constructivist learning principles of Dewey and Bruner, was to address the effectiveness of the local university's existing remedial program in assisting the teacher education …

Elementary Teachers' Perceptions Of Response To Intervention And Classroom Instruction, Lora Coonce

Walden Dissertations and Doctoral Studies

Response to intervention (RTI) is a federal program created to improve student learning and reduce the number of students misidentified as needing special education services. Differing interpretations of how best to implement RTI between campuses and districts have resulted in teachers' confusion and misperceptions of the program. The purpose of this study was to understand how elementary classroom teachers' perceptions of RTI affect classroom instruction. Based on Gagne's instructional theory and Bruner's theory of constructivism, the study examined the perceptions of 10 classroom teachers in 2 low socio-economic elementary schools. The study examined how RTI forms and protocols, administrative leadership, …

Determining Sustainable Strategies For Directors Of Microfinance Banks In Nigeria, Josephine Aruoriwo Diete-Spiff

Walden Dissertations and Doctoral Studies

The Nigerian microfinance banks often close their offices abruptly, leading to the loss of shareholders' funds. The purpose of this phenomenological study was to explore strategies microfinance bank directors use to maintain business sustainability. The concepts of microfinance banking, sustainability value, and strategic management theory formed the conceptual framework for this study. Twenty managing directors from microfinance banks in the Anambra state of Nigeria participated in semistructured interviews. The data analysis process involved the use of Moussakas' modified van Kaam process, which resulted in the emergence of 3 themes: strategic management, fear of microlending, and maintaining sustainability. The emergent themes …

Small And Medium Enterprises' Profitability Elements In Green Energy Transactions, Humphrey Edereka Great

Walden Dissertations and Doctoral Studies

As the primary drivers of Nigeria's economy, small and medium scale enterprise (SME) leaders rely on standby generators for sustainable business operation. Because of this reliance, over 56% of the SMEs operate far below capacity from the effects of power shortages. Guided by the strategic contingency theory, this study explored the profitability strategies of business leaders faced with electricity disruptions within Abuja Federal Capital Territory while adopting corporate social responsibility (CSR) and green practices. Data collection was through face-to-face semistructured interviews using open-ended questions. Participants consisted of 12 business leaders selected from 4 SME categories within Abuja that have imbibed …

Of the total number of child specific consultations or cases referred for services in Maryland (unlicensed), N = 370, n = 266 children avoided expulsion and were able to remain at their childcare placements while n = …

An Investigation Of Teacher Experiences With Implementation Of A Response To Intervention Model, Jennifer H. Murphy

Walden Dissertations and Doctoral Studies

A Southeastern school district was in the initial phases of a response to intervention (RtI) model using 3 tiers of intervention prior to students being identified for participation in special education. General education classroom teachers were responsible for all Tier I interventions by differentiating the core curriculum. However, teachers received little to no specific training related to implementation, progress monitoring, and data analysis of these differentiated interventions. This case study examined teachers' perceptions of the current implementation of RtI in one elementary school and their perceptions of professional support needed to implement, assess, and analyze RtI data. This qualitative research …

Exploring The Lack Of African Americans In The Department Of Defense Senior Executive Service Corps, Audrea Maria Nelson

Walden Dissertations and Doctoral Studies

There is a lack of African American representation in the Department of Defense's (DoD's) Senior Executive Service (SES) Corps. In 2011, only 11.4% of the DoD's SES members were African American. This disparate representation is problematic because it contradicts the creation of a diverse workforce, which in turn limits opportunities for African Americans to join the elite DoD SES Corps. The purpose of this phenomenological study was to explore the perceptions of 9 African American SES members in the Office of the Secretary of Defense, Defense Agencies, and Defense Field Activities to determine factors contributing to their promotions into the …

Walden Dissertations and Doctoral Studies

White collar corporate corruption continues to be prevalent in the United States, costing shareholders billions of dollars annually. This study of the collapse of Coudersport, PA firm, Adelphia Communications, explored how and why leadership of this prominent and successful company made unethical decisions, created an atmosphere of moral disengagement, and led to the downfall of the company. Taped interviews with 10 executives who were employed at the company during the years of its rise and demise (1996-2006) were transcribed, hand coded, and analyzed to explore the ethical culture and leadership practices at Adelphia. These insights offer a possible explanation for …

Relationship Of Solar Energy Installation Permits To Renewable Portfolio Standards And Insolation, Kirt Gordon Butler

Walden Dissertations and Doctoral Studies

Legislated renewable portfolio standards (RPSs) may not be the key to ensure forecast energy demands are met. States without a legislated RPS and with efficient permitting procedures were found to have approved and issued 28.57% more permits on average than those with a legislated RPS. Assessment models to make informed decisions about the need and effect of legislated RPSs do not exist. Decision makers and policy creators need to use empirical data and a viable model to resolve the debate over a nationally legislated RPS. The purpose of this cross-sectional study was to determine if relationships between the independent variables …

Autonomy In The California Disability Services System, Lisa Ann S. Carbone

Walden Dissertations and Doctoral Studies

Legislation concerning California residents with intellectual and developmental disabilities (ID/DD) requires recipients of services to be treated as independent individuals while emphasizing self-determination. At the same time, under regulatory procedures, recipients are considered dependent on the delivered services and not self-determinant. Neither the California Department of Developmental Services nor the trade associations representing community service providers have established a unified, systematic practice to support self-determination. This phenomenological study explored the experience of adults with ID/DD working toward self-determination.

Specifically, it explored how medical and social models contribute to shaping and actualizing the independence of this population. Interviews with eight adults …

Foreign Language Teaching And Learning, Aleidine Kramer Moeller, Theresa Catalano

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Foreign language teaching and learning have changed from teacher-centered to learner/learning-centered environments. Relying on language theories, research findings, and experiences, educators developed teaching strategies and learning environments that engaged learners in interactive communicative language tasks. A shift in foreign language pedagogy from a specific foreign language method to the measurement of language performance/competency has resulted in a change in the role of the teacher from one of authority/expert to that of facilitator/guide and agent of change. Current developments point to public pedagogy, social media, and action research as additional ways to foster intercultural competence and language learning.

The Teacher-Artist's Creed: Teaching As A Human, Artistic, And Moral Act, Amanda Morales, Jory Samkoff

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Historically, educators and philosophers have struggled to define the role and the value of formal curriculum and its impact on classroom praxis. As the current accountability movement dominates discussions in education, educators are pressured to implement increasingly standardized curricula. The authors of this chapter consider the tensions arising from this trend, situated first within contrasting theories on teaching and learning. They then explore the concept of phronesis through an interpretive biography of one teacher-artist, Frieda, whose praxis also demonstrates the aesthetic and artistic side of the teaching-learning process. This 90-year-old teacher-artist's experiences implementing her curriculums suggest that it is always …

Education Policy Implementation In The New Latino Diaspora, Jennifer Stacy, Edmund T. Hamann, Enrique G. Murillo Jr.

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Villages, towns, and cities throughout the United States, including the 41 states of the New Latino Diaspora (NLD), continue to host/receive heterogeneous populations of Latinos who transform the physical and cultural landscape in ways that require social institutions, like schools and universities, to respond. Increasingly, this transformation includes newcomer parents starting families. Thirty-three percent of the U.S. Hispanic population is age 18 or younger, while that age profile is true of slightly below 20% of non-Hispanic Whites (Pew Hispanic Center, 2012). While voter rolls and retirement community residents may remain much Whiter than the U.S. population as a whole for …

School Violence And Teacher Resiliency At A Midwest Elementary/Middle School, Jounice Blackmon Wright

Walden Dissertations and Doctoral Studies

The purpose of this phenomenological study was to investigate, from the perspective of teachers, the possible effect of school violence on teacher resiliency. School violence has been studied with respect to student behavior and academic success, as well as socioeconomic influences, but not with respect to teacher resiliency, as expressed by teachers themselves. Resiliency theory was the conceptual framework. Participants were all teachers of Grades 2-8 at an elementary/middle school in the Midwest. Twelve in-depth interviews were transcribed into text data and analyzed for common themes. Using NVivo, Version 10, I was able to more easily manage the volumes of …

Assessing The Significance Of Modularizing Contract Manufacturing Organizations, Christian Sampson Yorgure

Walden Dissertations and Doctoral Studies

Organizations are under constant threat from global competition, socioeconomic factors,

and political forces that are often unforeseen and dynamic. Consequently, decision

makers adopt strategies, some including the principles of modularity, as a

countermeasure. The problem addressed in this study was the lack of knowledge about

the significance of modularizing contract manufacturing organizations (CMOs). The

purpose of this quasi-experimental study was to assess the significance of modularizing

CMOs by statistically analyzing capacity utilization, efficiency, and profit margin

between modular and nonmodular departments in a focal CMO. This study was grounded

in the theory of modularity and the research question addressed what …
