Information Technology Management And Emotional Intelligence, Tina M. Muheim

Walden Dissertations and Doctoral Studies

Information technology (IT) employees often face high stress, burnout, and turnover, indicating a potential gap in IT leaders’ emotional intelligence (EI), which may hinder their ability to support and retain their teams effectively. Since IT plays a critical role in organizational performance and achieving strategic goals, addressing this gap is crucial for improving team well-being and organizational success. Grounded in EI theory, the purpose of this quantitative correlational study was to examine the relationship between IT managers’ EI subscales—assertiveness and interpersonal relationships—and their influence on the EI subscale, happiness/well–being indicator. The participants were 38 IT managers from U.S. organizations who …

Periodic Fever, Aphthous Stomatitis, Pharyngitis & Cervical Adenitis, Sonia P. Wheat

Walden Dissertations and Doctoral Studies

The suffering of children with periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) is well documented and includes diminished quality of life (QoL), emotional/behavioral problems, fatigue, food avoidance and school absenteeism. As an example of childhood adversity, and because the model of pediatric medical traumatic stress demonstrates traumatic responses do not always subside over time, this study examined the psychosocial health of PFAPA survivors post resolution. Using a quantitative, cross-sectional study design, the psychosocial well-being of PFAPA survivors was compared to children with persistent asthma and children without chronic illness or a history of medical trauma. Two validated parent-completed …

Selectivity Of Invasive Species Suppression Efforts Influences Control Efficacy, Rae Fadlovich, Kevin Landom, Timothy E. Walsworth

Watershed Sciences Student Research

1. Highly fecund invaders and size-selective suppression efforts often limit the effectiveness of invasive species control programs, as compensatory processes can allow suppressed populations to recover. While population models have long explored how demographic characteristics impact management feasibility, there is a growing need to evaluate how the selectivity of suppression efforts might impact the long-term feasibility of control.
2. We use a simulation framework that integrates age-based selectivity to evaluate the effect of increasing the range of ages selected for during harvest-based invasive species control. We applied this approach to common carp in Utah Lake, the location of one of the world's …

Exploring Nutritional Needs In Spinal Cord Injury: Dietitian Perspectives, Bowel Health, And Dietary Recommendations, Ayse Gul Zengul

All ETDs from UAB

Spinal cord injury (SCI) is a global condition affecting millions of people and leading to life-altering health complications. It profoundly alters body composition and metabolic rate, which need to be addressed with SCI-specific nutritional strategies. Muscle atrophy, fat accumulation, and decreased energy expenditure often lead to secondary health complications such as chronic diseases and SCI-related health problems, including pressure injuries and bowel dysfunction. Although nutrition plays a critical role in SCI management, our understanding of specific dietary needs for this population remains incomplete. This dissertation aims to comprehensively investigate the nutritional challenges and needs of individuals with SCI, ultimately developing …

Unraveling The Kinetic Mechanisms Of Protein Unfolding And Translocation Catalyzed By Hsp100 Unfoldases, Jaskamaljot Kaur Banwait

All ETDs from UAB

Escherichia coli ClpB and Saccharomyces cerevisiae Hsp104 are part of the Hsp100 family of proteins responsible for maintaining protein homeostasis in a cell during heat-stress conditions. Structurally, ClpB and Hsp104, in their active state, assemble into hexameric ring complexes with a hollow axial channel. Functionally, these enzymes are hypothesized to couple energy from ATP binding and hydrolysis to unfold protein substrates and translocate them through their axial channel. However, the molecular mechanisms of protein unfolding and translocation catalyzed by both ClpB and Hsp104 are not well understood. In this dissertation, we report the development of a single-turnover transient state kinetics …

Role Of Ring-Box E3 Ligases In Runx2 And Sp7 Protein Turnover During Osteoblast Differentiation, Abeera Sikandar

All ETDs from UAB

The bone matrix synthesis by osteoblast during skeletogenesis is regulated by several transcription factors and signaling pathways. Runx2 and Sp7 are master regulators of osteoblast differentiation and bone formation. Deletion of both genes in mice results in the complete failure of ossification. In humans, Sp7 and Runx2 genes mutations cause osteogenesis imperfecta and cleidocranial dysplasia, respectively. The progression of osteoblast differentiation requires a coordinated and temporal expression of Runx2 and Sp7 genes. Posttranslational modifications regulate the cellular levels and function of Runx2 and Sp7 proteins. Ubiquitination controls protein turnover through targeted degradation. The multi-subunit SCF-complex is the largest class of …

Mitigating The Impacts Of Future Climate Change On Urban Infrastructure In Alabama Through Updating Precipitation Intensity-Duration-Frequency (Idf) Curves, Kofi Ntow Opare

All ETDs from UAB

Climate change is set to profoundly impact urban infrastructure, causing increased flooding and storm damage, necessitating the reevaluation and adaptation of design methodologies to account for increasing precipitation extremes. This dissertation aims to enhance the resilience of urban infrastructure in Alabama by updating Precipitation Intensity-Duration-Frequency (IDF) curves, which are crucial for designing stormwater management systems, drainage networks, and flood control structures. Traditional IDF curves, derived from historical rainfall data, operate under the assumption of stationarity, an assumption increasingly invalidated by climate change. This research employs the Generalized Extreme Value (GEV) distribution and compares the efficacy of L-moments and Generalized Maximum …

Gendered Sexual Behaviors: Unintended Pregnancies, And Sexually-Transmitted Infections, Deirdre Ferguson

All ETDs from UAB

Education is the most effective way to address unintended pregnancies and sexually-transmitted infections (STIs). Education through preventative counseling has been negatively correlated with unintended pregnancies. Although research has shed light on the risks posing challenges to the prevention of unintended pregnancies, the consequential costs of these pregnancies continue to mount, both individually and societally. Birth control counseling corresponds with reducing the behavior of nonuse of contraceptives significantly. Education is thus associated with combatting inaccurate information passed along via primary social groups. To gain insight into the prevention of unintended pregnancies and STIs, data was gathered using a mixed-method approach incorporating …

Chronic Inflammation Compromises Natural Killer Cell Phenotype And Function In Myeloid Leukemia, Valeriya Kuznetsova

All ETDs from UAB

Chronic myeloid leukemia (CML) and acute myeloid leukemia (AML) are blood malignancies characterized by clonal expansion and a compromised immune system. Tyrosine kinase inhibitors (TKI) revolutionized CML treatment; however, TKI discontinuation leads to relapses in half of the cases. Further, up to 10% of patients are TKI-resistant and develop a blast crisis resembling AML. Natural killer (NK) cells can clear malignant cells, representing a promising immunotherapy. However, NK cell activity is suppressed in leukemia, and the microenvironmental drivers of this impairment remain understudied. Despite this, the existing mouse models have not been tested to assess the effect of CML on …

The Evolutionary Ecology Of Reproductive System Variation In Haploid-Diploid Freshwater Red Macroalgae, Sarah Connelly

All ETDs from UAB

Reproductive systems describe the relative rates of sexual versus asexual reproduction and selfing versus outcrossing, governing the transmission of genetic diversity between generations and shaping evolutionary responses to environmental change. Though sex has inherent costs, it contributes to the reproductive system for most eukaryotes, generating incredible life cycle diversity. Life cycles are expected to be correlated with different reproductive systems. Diploid life cycles should be associated with outcrossing, whereas life cycles with a long-lived haploid phase are hypothesized to be associated with selfing and asexual reproduction. To test this hypothesis, we used ten polymorphic microsatellite loci to genotype 311 gametophytes …

The Role Of The Executive Control Network In Social Functioning In Autism, Mckayla Kurtz

All ETDs from UAB

Social functioning difficulties are often seen in autism and impact one’s ability to engage in meaningful social interactions and to maintain social relationships. Emerging research suggests that executive function (EF) impairments may underlie these social challenges, though the neural mechanisms involved remain unclear. The current study aimed to investigate the relationship between the functional connectivity of the executive control network (ECN) and social functioning in autistic children using resting-state functional MRI (rsfMRI) data. Resting-state fMRI data was obtained from 95 autistic participants (ages 5-13 years) from the publicly available Autism Brain Imaging Data Exchange II (ABIDE-II) database. Data were preprocessed …

Single Nucleus Multiomics Reveals The Drought-Driven Gene Regulatory Atlas In Arabidopsis, Jinbao Liu

All ETDs from UAB

The regulation of gene expression in plant responses to drought has been thoroughly in-vestigated in previous studies. Despite this, a detailed understanding of the cell type-specific regulatory mechanisms, encompassing multi-layered biological processes, is lack-ing. In this study, we report the use of single nucleus multiomic analysis in Arabidopsis seedlings in response to drought stress. Our single-nuclei RNA (snRNA) analysis deline-ated 14 distinct clusters representing major root and shoot cell types and discovered new cell type-specific drought markers. Integration of snRNA with single-nuclei ATAC (snATAC) data in leaf epidermis, root endodermis, and guard cells revealed accessible chromatin regions (ACRs)-linked genes predominantly …

The Development Of A Valid And Reliable Survey To Assess Sexual And Reproductive Health Knowledge, Practices, Beliefs, And Risk For Abuse In Adults With Spina Bifida, Betsy Hopson

All ETDs from UAB

Adults with spina bifida (SB) face significant sexual and reproductive health (SRH) challenges, including knowledge gaps, limited access to services, and increased vulnerability to abuse. Sexual health is critical for this population, as most now live into adulthood. By age 20, many individuals with SB are sexually active, and over 90% express a desire for sexual activity. However, only 5% have discussed SRH with a healthcare provider, leading to sexual dysfunction, low contraception use, and inadequate SRH knowledge. Despite guidelines from the Spina Bifida Association (SBA) advocating for patient-centered SRH communication, healthcare providers’ lack of training and discomfort in having …

Scalable Resonance-Based Multi-Coil Inductive Links For Wireless Power Transmission And Passive Sensing In Biomedical Applications, Reepa Saha

All ETDs from UAB

Type 2 Diabetes (T2D) has become a major health crisis, affecting up to 95% of the 38.4 million diabetes cases in the United States and costing approximately $327 billion annually. Current treatments mainly focus on symptom management rather than reversing the disease. However, clinical observations suggest a promising link between certain stomach surgeries, such as the removal of the upper stomach, and diabetes reversal within a year. This raises the possibility of anatomical changes influencing diabetes outcomes, though the underlying neural mechanisms remain unclear. This dissertation is organized into three interconnected research segments, each contributing to a platform that deepens …

KCNQ2 variants in children with neurodevelopmental impairment are difficult to assess due to their heterogeneity and unclear pathogenic mechanisms. We describe a child with neonatal-onset epilepsy, developmental impairment of intermediate severity, and KCNQ2 G256W heterozygosity. Analyzing prior KCNQ2 channel cryoelectron microscopy models revealed G256 as a node of an arch-shaped non-covalent bond network linking S5, the pore turret, and the ion path. Co-expression with G256W dominantly suppressed conduction by wild-type subunits in heterologous cells. Ezogabine partly reversed this suppression. Kcnq2G256W/+ mice have epilepsy leading to premature deaths. Hippocampal CA1 pyramidal cells from G256W/+ brain slices showed hyperexcitability. G256W/+ pyramidal …

Scproatlas: An Atlas Of Multiplexed Single-Cell Spatial Proteomics Imaging In Human Tissues, Xi Liu, Pora Kim, Liyu Huang, Kexin Huang, Xiaobo Zhou

Faculty, Staff and Student Publications

Spatial proteomics can visualize and quantify protein expression profiles within tissues at single-cell resolution. Although spatial proteomics can only detect a limited number of proteins compared to spatial transcriptomics, it provides comprehensive spatial information with single-cell resolution. By studying the spatial distribution of cells, we can clearly obtain the spatial context within tissues at multiple scales. Spatial context includes the spatial composition of cell types, the distribution of functional structures, and the spatial communication between functional regions, all of which are crucial for the patterns of cellular distribution. Here, we constructed a comprehensive spatial proteomics functional annotation knowledgebase, scProAtlas (https://relab.xidian.edu.cn/scProAtlas/#/), …

Land-Use Effects On Soil Organic Matter And Related Soil Properties In A Mixed Agricultural–Forest Landscape Of Central Wisconsin, Usa, Kathryn L. Hofmeister, Gwen Feitl, Kaylee Tackett, Leah Fleury, Lucas E. Nave

Michigan Tech Publications

Soil organic matter (SOM) influences a wide range of ecosystem processes, including nutrient cycling, water movement, plant productivity, and biodiversity. In agricultural landscapes, adjacent land uses often differ in SOM contents and related soil properties, such as soil organic carbon (SOC) stocks, but the direction and magnitude of these effects are inconsistent across studies. We assessed how land uses differed in SOM and related properties in a representative US Midwest agricultural–forest landscape to support land-use and management decisions by local landowners and producers. We measured SOM, bulk density (Db), root biomass, and pH, and estimated SOC stocks, in a Typic …
