Walden Dissertations and Doctoral Studies

AbstractThis study, using feminist trauma theory as the conceptual framework, addressed a gap in the literature about female university students’ experiences with posttraumatic stress disorder (PTSD) related to the academic and social supports needed for college success and degree completion. Nearly 30% of college students will drop out during their 1st year in school. Research suggests that personal histories of simple and complex traumas may be influential factors contributing to dropout rates. There are limited programs or resources in colleges and universities to address the needs of students struggling with past traumas aside from routine student counseling. The purpose of …

Factors For Lgbt College Students That Predict Academic Success, Jonathan Mccormick

Walden Dissertations and Doctoral Studies

Much research has been done on LGBT students in relation to campus climate and academic achievement, which suggested that a positive campus climate may positively influence students’ academic success. However, no research has yet been done to understand the value of campus climate, student levels of depression anxiety and stress, and student level of outness for predicting academic success. This quantitative study examined campus climate, depression, anxiety, and stress levels, and student level of outness together in their ability to predict self-reported grade point average of LGBT college students. Basic Psychological Needs Theory, a sub theory of Self-Determination Theory, was …

Generalized Anxiety Disorder Symptoms Stratified By Age In Primary Care, Robin E. Mccoy

Walden Dissertations and Doctoral Studies

Little is known as to the age-related presentation of somatic complaints of those diagnosed with generalized anxiety disorder in primary care settings. A retrospective medical records review sought to identify the affective symptoms of generalized anxiety disorder (GAD) by age as recorded by primary care providers and to test the association of these symptoms by age. Guided by Engle’s (1977) biopsychosocial (BPS) model, a large administrative claim database system was used to derive a sample of 1,336, including 500 patients diagnosed with generalized anxiety disorder between 2018 to 2021. Binary logistics regression, one-way ANOVA, chi-square, correlation, and logistical regression with …

The study …

Effect Of Single-Gender Education On Girls' Success In Math, Joseph Moody

Walden Dissertations and Doctoral Studies

Prior research suggested that all students were not treated equally in the educational setting and that boys perform better than girls on standardized tests. The purpose of this quantitative study was to examine how class composition affected performance on the math section of the Educational Records Bureau (ERB) test and Preliminary SAT (PSAT) among girls who took single-gender classes and girls who remained in coed math classes. Gender essentialism and gender constructivism are important to the study of single-gender education because the foundation of single-gender education is in understanding brain development to design a classroom that allows for differences to …

Pancreatic Cancer: Quantitative Study Investigating The Regional Risk Factors In North Carolina, Holly Marie Myers

Walden Dissertations and Doctoral Studies

Pancreatic cancer is the fourth-leading cause of cancer-related deaths in the United States, killing more than 90% of individuals diagnosed within 5 years. Due to the lack of signs and symptoms, 82% of all pancreatic cancer cases are diagnosed in terminal stages. As such, the most powerful method to reducing the morbidity and mortality of pancreatic cancer is to further investigate the risk factors. According to the theoretical framework of the ecosocial theory, long-term exposure to exposures to unfavorable socioecological and environmental factors serve as a “web of causation” for adverse health outcomes. Using data from the North Carolina Department …

The purpose of this study was to explore and describe the social networking and self-efficacy of currently homeless and those who have successfully transitioned to supportive housing in the unique social and geographical environment of O’ahu, Hawai’i. A phenomenological study design using criterion sampling for semi structured interviews of four houseless …

Examining Psychosocial Characteristics Of Female Serial Murderers, Rachael Strebel

Walden Dissertations and Doctoral Studies

Previous studies of serial murderers have focused primarily on male serial murderers.The reason for this is unknown, but is primarily reflective of media patterns, gender roles, and social norms that often exclude females from conversations surrounding female serial murder. This study focused on the psychosocial characteristics of female serial murderers. Both solo female serial murderers and serial murderers who worked with one partner were studied. Using a grounded theory approach, based on the review of 11 secondary data case studies, 12 female serial murderers were studied; six who murdered individually and six who murdered within a team. Six main themes …

Parenting From Juvenile Confinement: Adults’ Reflections On Their Juvenile Experience, Lakeasha R. Moore

Walden Dissertations and Doctoral Studies

AbstractMass incarceration in the United States has resulted in an estimated 19.7 million youth living in fatherless homes. Incarcerated juvenile fathers are contributing to that number. Juvenile fathers who are incarcerated is a socially pertinent topic with significant implications, yet child developmental scholars understudy it. This phenomenological qualitative study was conducted to fill this gap by exploring the lived experiences of adults who, as juveniles, were incarcerated fathers and how they coped with social and emotional stressors while attempting to balance adolescence and defining fatherhood. Five adult males were interviewed and asked a series of four demographic and 18 semistructured …

The Forgotten Sexual And Gender-Based Violence Of The Vietnam-American War: Is Justice Too Late For Vietnamese Victims And Survivors?, Madison P. Bingle

Human Rights Brief

“The past, far from disappearing or lying down and being quiet, has an embarrassing and persistent way of returning and haunting us unless it has in fact been dealt with adequately.” —Desmond Tutu

The Vietnam-American War ended nearly fifty years ago. However, the atrocities committed during the war have had a devasting impact on the lives of persons involved long after the conflicts’ end. A particularly marginalized group within survivors and victims of the Vietnam-American War is Vietnamese women who experienced sexual and gender-based violence. And given the specific tactics of warfare employed during this war, including the use of …

High School Science Students’ Cognitive Load Using Virtual Reality Compared To Traditional Instruction, Maria Carmen R. Lagalante

Walden Dissertations and Doctoral Studies

Cognitive load is the effort needed to process and store information in memory and can be measured via subjective, physiological, and performance methods. Virtual reality learning environments (VRLEs) enhance science aptitude and motivate students to pursue science careers. Cognitive load is divided into three types: intrinsic, extraneous, and germane. Using cognitive load theory as the framework, the problem addressed through this study was that it is not yet fully understood what the effect of VRLEs is on students’ cognitive load, which can hinder their learning if it is too high. Secondary science education comprises many complex topics with significant levels …

A Methodology For Statistical Mean Wave Climate Regime Characterisation In Oceanic Islands: The Case Of The Southern Coast Of Tenerife, Emilio Megías, Manuel García-Román

Journal of Marine Science and Technology–Taiwan

Oceanic islands of volcanic origin tend to have peculiar characteristics, such as: exposure to many wave directions; grouping in archipelagos; steep coastal slopes; and small coastal shelves. All these features require certain considerations in wave climate studies. These types of studies, when wave spectra are not available and have to be performed with parametric data, can be unreliable without an adequate systematic treatment. In this work we propose a methodology consisting of pre-classification according to the peak period and subsequent separation into different sectors according to the geographical fetch. The island of Tenerife is the case study, and in particular …

Politics And The Criminal Enforcement Of The Toxic Substances Control Act, Dr. Joshua Ozymy, Dr. Melissa Jarrell Ozymy, Dr. Danielle Mcgurrin

Seattle Journal of Technology, Environmental, & Innovation Law

Environmental crimes related to chemical substances are governed under the Toxic Substances Control Act (TSCA). When these violations involve significant harm or culpable conduct they may be remedied through criminal prosecution. While Democratic and Republican presidents have offered historically varied support for criminal enforcement, we know very little about how politics affects TSCA enforcement outcomes or TSCA criminal enforcement generally. To address these issues, we performed a content analysis of 2,728 criminal prosecutions from 1983-2021 that derive from the United States Environmental Protection Agency (EPA) criminal investigations and select all TSCA prosecutions. Results show 75 prosecutions were adjudicated, involving 137 …

Engineering, Computing & Construction Management Faculty Publications

Transportation agencies need information about the potential effects of climate change on the volume, quality, and treatment of stormwater to mitigate potential effects of runoff on receiving waters. To address these concerns, the U.S. Geological Survey and the Federal Highway Administration used the Coupled Model Intercomparison Project tool and the Stochastic Empirical Loading and Dilution Model to perform space-for-time stormwater quality analyses. This study indicated that spatial variations in precipitation statistics within and adjacent to southern New England are greater than projected climate-related changes for the centroid of this region. A dilution-factor analysis indicated that highway runoff would become a …

Identification Of Ywhah As A Novel Brain-Derived Extracellular Vesicle Marker Post Long-Term Midazolam Exposure During Early Development, Nghi M. Nguyen, Daniel Meyer, Luke Meyer, Subhash Chand, Jagadesan Sankarasubramanian, Maireen Miravite, Chittibabu Guda, Sowmya V. Yelamanchili, Gurudutt Pendyala

Journal Articles: Anesthesiology

Recently, the long-term use of sedative agents in the neonatal intensive care unit (NICU) has raised concerns about neurodevelopmental outcomes in exposed neonates. Midazolam (MDZ), a common neonatal sedative in the NICU, has been suggested to increase learning disturbances and cognitive impairment in children. However, molecular mechanisms contributing to such outcomes with long-term MDZ use during the early stages of life remain unclear. In this study, we for the first time elucidate the role of brain-derived extracellular vesicles (BDEVs), including mining the BDEV proteome post long-term MDZ exposure during early development. Employing our previously established rodent model system that mimics …

Journal Articles: Genetics, Cell Biology & Anatomy

Porous alginate (Alg) hydrogels possess many advantages as cell carriers. However, current pore generation methods require either complex or harsh fabrication processes, toxic components, or extra purification steps, limiting the feasibility and affecting the cellular survival and function. In this study, a simple and cell-friendly approach to generate highly porous cell-laden Alg hydrogels based on two-phase aqueous emulsions is reported. The pre-gel solutions, which contain two immiscible aqueous phases of Alg and caseinate (Cas), are cross-linked by calcium ions. The porous structure of the hydrogel construct is formed by subsequently removing the Cas phase from the ion-cross-linked Alg hydrogel. Those …

Gurumurthy, Hinrich Staecker, Xuezhong Liu, Zheng-Yi Chen

Journal Articles: Genetics, Cell Biology & Anatomy

Patients with mutations in the TMPRSS3 gene suffer from recessive deafness DFNB8/DFNB10. For these patients, cochlear implantation is the only treatment option. Poor cochlear implantation outcomes are seen in some patients. To develop biological treatment for TMPRSS3 patients, we generated a knockin mouse model with a frequent human DFNB8 TMPRSS3 mutation. The Tmprss3^A306T/A306T homozygous mice display delayed onset progressive hearing loss similar to human DFNB8 patients. Using AAV2 as a vector to carry a human TMPRSS3 gene, AAV2-hTMPRSS3 injection in the adult knockin mouse inner ear results in TMPRSS3 expression in the hair cells and the spiral ganglion neurons. …

Advances In Antimicrobial Peptide Discovery Via Machine Learning And Delivery Via Nanotechnology, Alexa Sowers, Guangshun Wang, Malcolm Xing, Bingyun Li

Journal Articles: Pathology and Microbiology

Antimicrobial peptides (AMPs) have been investigated for their potential use as an alternative to antibiotics due to the increased demand for new antimicrobial agents. AMPs, widely found in nature and obtained from microorganisms, have a broad range of antimicrobial protection, allowing them to be applied in the treatment of infections caused by various pathogenic microorganisms. Since these peptides are primarily cationic, they prefer anionic bacterial membranes due to electrostatic interactions. However, the applications of AMPs are currently limited owing to their hemolytic activity, poor bioavailability, degradation from proteolytic enzymes, and high-cost production. To overcome these limitations, nanotechnology has been used …

Can Sotl Generate High Quality Research While Maintaining Its Commitment To Inclusivity?, Jill Mcsweeney, Matthew A. Schnurr

International Journal for the Scholarship of Teaching & Learning

The Scholarship of Teaching and Learning (SoTL) faces an emerging challenge as it seeks to balance commitments to disciplinary inclusivity and scholarly quality. We undertake a scoping review of 64 articles across three leading SoTL journals to investigate how the literature balances these twin commitments by exploring what questions are being asked, what methods are being used, and how these may be impacting the inferences that are being made within that scholarship. We advocate for a more focused definition of SoTL that can help reinforce its legitimacy within institutional power structures of scholarship, and for partnerships across disciplinary boundaries to …

Designing And Reflecting On Active Learning And Flipped Classrooms For Renal Physiology, Bernard Thomas Drumm Dr

International Journal for the Scholarship of Teaching & Learning

In this paper, we outline a case study describing the incorporation of active learning and flipped classroom techniques in a renal physiology module in 1st year medical school. The module was redesigned over a 2-year period within the teaching for understanding (TfU) framework (generative topics, understanding goals, performances of understanding and ongoing assessment) to include more active learning exercises (clicker response systems centered on clinically relevant problem sets and classroom assessment techniques – CATs), which culminated in flipping the classroom entirely during the 2nd year. The goal, was to evaluate student perceptions of the flipped classroom model and to reflect …

Parental Affect Profiles Predict Child Emotion Regulation And Classroom Adjustment In Families Experiencing Homelessness, Madelyn H. Labella, Rebecca Distefano, Jillian S. Merrick, Jyothi L. Ramakrishnan, Eric L. Thibodeau, Ann S. Masten

Arts & Sciences Faculty Publications

Parenting shapes the development of emotion regulation skills in early childhood, laying a key foundation for social-emotional adjustment. Unfortunately, high adversity exposure may disrupt parental emotion socialization practices and children's regulatory development. The current study used variable- and person-centered approaches to evaluate links among parental emotion expressiveness, children's observed emotion regulation, and teacher-reported adjustment among 214 4- to 6-year-old children experiencing homelessness, an indicator of high cumulative risk and acute adversity. Structured parent-child interaction tasks were recorded on site in emergency shelters over the summer and micro-socially coded for parent and child expressions of anger, positive affect, and internalizing distress. …
