The Price Of Possessiveness: How Parental Materialism Undermines Child Psychological Wellbeing, Miao Li

Sociology Publications

Materialism, a value system that places the pursuit of possessions at the core of happiness and life meaning, is a dominant cultural force in modern societies. While its associations with individual well-being are well-documented, its intergenerational implications remain understudied. This study conceptualizes materialism as a potential family stressor contributing to the intergenerational transmission of stress. An intergenerational crossover model of materialism was tested using data from 1,996 parent-child pairs in Zhengzhou, China. Results indicate that higher parental materialism is associated with stronger materialistic values in children, weaker family relationships, and more frequent parental comparisons, each of which is linked to …

Nitrate Levels In The Tap Water Of Several Northeast Iowa Communities In 2026, Kamyar Enshayan

Faculty Publications

Tap water samples were taken from numerous sites in several northeast Iowa communities along the Cedar River to learn what levels of nitrate people are actually drinking over a several-months period in 2026, with the hope of inspiring public conversations, understanding and action. Samples were taken from February to June 2026.  None of the tap water samples violated the current outdated nitrate limit of 10 mg/l set 35 years ago. However, published public health studies in the past 15 years reveal that consuming nitrate in drinking water at levels as low as 5mg/l for a long time can increase the …

Understanding College Student Expectancies Of Simultaneous Engagement In Multiple Risk Behaviors: A Measurement Development And Model Testing Study, Shelby Whalen

Electronic Theses and Dissertations

Risky behaviors, actions that may cause physical, psychological, social, or economic harm to oneself or others, are prevalent among college students. While significant research has focused on single high-risk behaviors of alcohol use, drug use, gambling, and gaming separately, students frequently engage in multiple high-risk behaviors simultaneously, such as drinking alcohol while gambling. Research shows that students have distinct and specific expectancies about what happens when they engage in a risk behavior, however, minimal research has examined students’ perceptions or reasons for simultaneous poly-risk behavior engagement. This multi-phase project characterized students’ outcome expectancies for simultaneous poly-risk behavior combinations, developed and …

The Memphis Gambling Screen: A Clinical Validation Study Of An Enhanced-Readability Self-Report Measure For Gambling Disorder, Natasha Bourgoin

Electronic Theses and Dissertations

Precise identification of gambling disorder can be difficult when commonly used screeners vary in clarity and diagnostic accuracy. The Memphis Gambling Screen (MGS) was developed as an enhanced-readability self-report measure to improve item comprehension and strengthen the diagnostic accuracy of DSM-5 gambling disorder. This study evaluates the psychometric properties and diagnostic accuracy of the MGS with a combined sample of individuals seeking treatment for problem gambling or substance use disorder and college students with a recent history of gambling (N = 232). Participants completed a demographic questionnaire, the MGS, and another commonly used measure, the Problem Gambling Severity Index …

Developing Solvent Tolerant Microbial Membranes: Lipid Extraction And Laurdan Fluorescence Approaches For Biofuel Optimization, Gladstone Anku

Electronic Theses and Dissertations

The high demand for sustainable energy has increased interest in advanced biofuels, though production is limited by solvent toxicity to microbial hosts. This study investigated the role of lipid composition in modulating membrane fluidity and solvent tolerance using Bacillus subtilis as a model organism. Five strains were cultured, and membrane lipids were extracted and analyzed using thin-layer chromatography and gas chromatography–mass spectrometry; however, inconsistent results limited compositional characterization. To address this problem, reconstituted vesicles composed of phosphatidylglycerol (PG) and phosphatidylethanolamine (PE) were used as model membranes. Membrane fluidity was assessed using Laurdan fluorescence spectroscopy by measuring generalized polarization (GP) values …

Disruption, Recovery, And Divergence: How Prepandemic Achievement Levels Shaped Learning Loss, Recovery, And Spending Efficiency In Tennessee Public High Schools, Wilson Boyd

Electronic Theses and Dissertations

The COVID-19 pandemic caused significant and uneven learning loss in Tennessee public high schools. The statewide ACT composite average fell from 20.2 in 2019 to 19.1 in 2021. By 2024-2025, it recovered only to 19.3. During the same period, Tennessee received approximately $3.86 billion in additional federal funds and $1.15 billion in new state funding. This ex post facto quantitative study examined whether prepandemic achievement levels predicted learning loss severity and recovery patterns of a census of 322 Tennessee public high schools from 2018-2019 through 2024-2025.

The study used two theoretical frameworks. Baumol's cost disease theory predicted that structural productivity …

Characterization Of Catechol-Type Siderophore(S) From P. Mosselii Cfml 90-83, Kemper R. Rasnake

Electronic Theses and Dissertations

Iron is essential for many biological processes, where it is used as a cofactor. Even though it is abundant in the Earth’s crust, it is in an insoluble form unavailable to microorganisms in the soil. To overcome this, bacteria produce siderophores, which are secondary metabolites that have a high affinity for iron. This allows bacterial cells to obtain insoluble iron that is essential for survival. Pseudomonas mosselii, a Gram negative bacterium, was isolated from soil. It was selected for further analysis as it was found to produce siderophore(s) under iron-limited conditions, which have not been characterized previously. Therefore, we aimed …

Kindergarten Aimsweb Ela Composite As A Predictor Of Third-Grade Reading Proficiency In A Rural, High-Poverty School District, Christi J. Gentry

Electronic Theses and Dissertations

Reading proficiency by the end of third grade is a critical milestone as students transition from learning to read to using reading as a tool for learning. In Tennessee, this proficiency is especially significant because promotion and retention decisions are linked to student performance on the Tennessee Comprehensive Assessment Program (TCAP) ELA assessment. This quantitative, longitudinal study examined the extent to which kindergarten readiness, operationalized as kindergarten AIMSweb ELA Composite scores, predicts third-grade reading proficiency status in one rural, high-poverty school district. Using archival student-level data, this study analyzed kindergarten AIMSweb ELA Composite scores and third-grade TCAP ELA proficiency. Logistic …

Staying The Course: Community College Student Lived Experiences On Program Completion And Motivation, Jessica Leigh Mills

Electronic Theses and Dissertations

The purpose of this phenomenological study was to explore the lived experiences of former community college students who successfully completed an associate degree, certificate, or program of study and to understand how they experienced the personal, institutional, and environmental factors that supported their persistence to completion. The study, guided primarily by Tinto’s (1975,1988) Model of Student Departure and was complemented by Bandura’s (1988) Social Learning Theory (SLT), and Maslow’s (1943) Hierarchy of Needs, explored the extrinsic and intrinsic motivations students attributed to their successful completion of their associate degree, certificate, or program of study. Twelve former community college students who …

A Geometric Morphometric Analysis Of Acetabular Shape Variation Across Bat Families, Jordan L. Huff

Electronic Theses and Dissertations

Bats are the only mammals capable of powered flight, and research is concentrated on this adaptation. Their non-flight locomotion has received comparatively little attention. Previous studies show that non-flight locomotor behaviors vary across families. Members of Pteropodidae are efficient climbers but cannot effectively walk, whereas Phyllostomidae and Vespertilionidae are better at terrestrial locomotion but show reduced arboreal capabilities. The non-flight locomotion of Hipposideridae and Rhinolophidae is less understood, although rhinolophids exhibit limited terrestrial locomotion. This study examined whether differences in locomotor behavior are associated with variation in acetabular morphology. A geometric morphometric analysis of acetabular shape was conducted across multiple …

Weathering More Than Storms: Understanding The Mental Health Disparities Of Black Farmers In The Appalachian Region, Aliyah Smith

Electronic Theses and Dissertations

Black farmers in Appalachia represent a vital and historically marginalized population within one of America’s most economically distressed regions. Black farmers have endured generations of systemic racism, resulting in land loss, economic hardship, and mental stressors. This study examines the intersection of race, agriculture, and behavioral health to illustrate how structural barriers and cultural stigmas shape the mental well-being of Black farmers across Appalachia.

Findings from the analysis will guide the development of a conceptual model based on constructs from the Social-Ecological Model (SEM), Intersectionality Theory, and Critical Race Theory (CRT). This study will use Key Informant Interviews (KIIs) conducted …

Population Health, East Africa

Background Urbanization is spatially heterogeneous in many sub-Saharan African settings. This complicates community health planning when rural and peri-urban labels are applied informally or updated inconsistently. We assessed whether multiple publicly available geospatial proxies could characterize settlement dynamics and support Community Health Unit (CHU) level classification within the Kaloleni Rabai Health and Demographic Surveillance System (KRHDSS) in coastal Kenya.

Methods We conducted a longitudinal ecological analysis across 10 CHUs in Kilifi County with annual observations from 2017 to 2024. Five geospatial proxy indicators of settlement intensity were summarized within CHU boundaries: Visible Infrared Imaging Radiometer Suite (VIIRS) nighttime lights radiance, …

Wisdom In Counseling And Psychotherapy: A Conceptual Model For Practice, Mitchell Waters

Papers

Wisdom is increasingly recognized as a critical construct in counseling and psychotherapy, yet it remains conceptually diffuse and underdeveloped for clinical application. This article proposes an integrative conceptual model of wisdom that extends the Dialectical Behavior Therapy (DBT) WISE MIND framework by incorporating temporal and self-transcendent dimensions. Wisdom is defined as a dynamic, context-sensitive capacity to coordinate cognitive, affective, temporal, and spiritual processes in response to complex life demands. The model includes four components: (a) cognitive–affective integration, reflecting the synthesis of emotion and reason; (b) temporal integration, involving adaptive coordination of past experiences and future possibilities; (c) self-transcendent orientation, conceptualized …

A Mindfulness-Based Stop Technique Training To Improve Nurses’ Knowledge And Self-Efficacy In Stress And Burnout Prevention, Rukiat Abolanle Afinni

Walden Dissertations and Doctoral Studies

Nurse burnout and stress are well-documented occupational concerns in outpatient clinical settings, where high patient acuity and chronic staffing shortages leave nurses with little structured support for proactive self-care. To address this gap, a mindfulness-based STOP (stop, take a breath, observe, proceed) training program was developed and evaluated for outpatient nurses. The evidence-based practice question was: Among nurses in an outpatient clinical setting, what is the impact of a mindfulness-based STOP technique training on nurses' knowledge of stress and burnout prevention and self-efficacy in applying the technique? A one-group pretest-posttest design was used with eight participants. A project-developed questionnaire measured …

The Relationship Between Maintenance And Overhaul Employee Spending, Business Model, Geographic Region, And The Financial Performance Of Commercial Airlines, Naumaan Khalid Sheikh

Walden Dissertations and Doctoral Studies

After nearly 5 decades of deregulation, commercial airline leaders still lack the capability to improve financial performance by structuring their maintenance operations to gain competitive advantages in highly competitive global markets. Without an effective strategy, airline maintenance affects service and financial performance. Framed with Porter’s competitive advantage theory, this quantitative nonexperimental correlational project was to examine the relationships between airline in-house maintenance and overhaul employee spending, business model, geographic region, and financial performance of global commercial full-service carrier (FSC) and low-cost carrier (LCC) airlines. Longitudinal panel data were collected from 121 LCCs and FSCs operating from 2001 to 2019 in …

Student Attitudes And Perceptions Of Proof In Mathematics, Emelin G. Sibrian Marquez

Electronic Theses, Projects, and Dissertations

Traditionally, mathematical proof is viewed primarily as a tool for validation or verification. However, proof holds many other important roles such as discovery, reasoning, explanation, and justification. For many students, these other roles are not always obvious. Those encountering rigorous proof for the first time often find the process abstract, intimidating or disconnected from their previous learning. This disconnect can lead to negative attitudes as students transition from computational mathematics to advanced proof-based mathematics. Utilizing a mixed-methods approach, this study examined undergraduate and graduate mathematics students at a Hispanic-Serving Institution (HSI) in Southern California. We investigated what students perceive the …
