The Ccjr® Charles A. Engh, Sr, Md. Excellence In Hip Research Award: Pelvic Tilt And Cup Position Change Significantly In Most Young Patients 10 Years After Hip Arthroplasty, Joseph J Kromka, William A Zuke, Caroline J Granger, John C Clohisy, Robert L Barrack

2020-Current year OA Pubs

BACKGROUND: Acetabular cup position is fundamental to total hip arthroplasty (THA) and surface replacement arthroplasty (SRA). Even if initial cup placement is adequate, changes in spinopelvic relationships alter functional acetabular position over time. This can lead to late complications. The purpose of this study was to examine changes in pelvic tilt and acetabular position in patients with at least 10 years of follow-up after THA or SRA.

METHODS: A retrospective review was conducted of patients from one academic practice who underwent THA or SRA and had at least 10 years of follow-up. Pelvic ratio was measured and converted to pelvic …

High-Density Lipoprotein-Associated Cholesterol Abnormalities In A Clinical Outcomes Study Of Dysferlin-Deficient Limb-Girdle Muscular Dystrophy Type R2, Zoe White, Alan Pestronk, Et Al.

2020-Current year OA Pubs

BACKGROUND: Limb-girdle muscular dystrophy (MD) type R2 (LGMDR2, formerly LGMD2B) is an autosomal recessive form of MD caused by variants in the dysferlin gene, DYSF. It leads to slow proximal and distal muscle weakening that generally results in loss of ambulation around early adulthood but without the lethal cardiorespiratory dysfunction observed in the more severe Duchenne MD. How loss of dysferlin causes muscle fibre death is poorly understood, but recent evidence suggests a link between muscle wasting and loss of muscle cholesterol homeostasis with circulating lipoprotein abnormalities in many forms of MD.

METHODS: Cross-sectional circulating total cholesterol (CHOL), high-density lipoprotein-associated …

2020-Current year OA Pubs

OBJECTIVE: To assess the differences in the symptoms associated with common otolaryngology complaints between male and female patients.

METHODS: Between June 2020 and July 2023, a multi-institutional cross-sectional study was performed at six tertiary academic otolaryngology practices using semantics-based questionnaires to assess the symptoms patients associate with the complaints of sinus infection, reflux, congestion, and dizziness. Patients selected symptoms from lists of proposed terms to describe the various conditions. The primary outcome measure was sex-related differences in respondent symptom selection.

RESULTS: Four separate questionnaires were completed by a total of 1495 patients (46.0% male, 54.0% female). Female patients more often …

Genetic Diversity And Expanded Phenotypes In Dystonia: Insights From Large-Scale Exome Sequencing, Mirja Thomsen, Joel S Perlmutter, Et Al.

2020-Current year OA Pubs

OBJECTIVE: Dystonia is one of the most prevalent movement disorders, characterized by significant clinical and etiological heterogeneity. Despite considerable heritability (~25%), the etiology in most patients remains elusive. Moreover, understanding correlations between clinical manifestations and genetic variants has become increasingly complex.

METHODS: Exome sequencing was conducted on 1924 genetically unsolved, mainly late-onset isolated dystonia patients, recruited primarily from two dystonia registries (DysTract and the Dystonia Coalition). Rare variants in genes previously linked to dystonia (n = 406) were examined, confirmed via Sanger sequencing, and analyzed for segregation when possible.

RESULTS: We identified 137 distinct likely pathogenic/pathogenic variants (according to ACMG …

Evolving Adaptive Foraging Robot Swarms With Neat In Environments With Obstacles, Tameem Uz Zaman, Pigar Biteng, Qi Lu

Computer Science Faculty Publications

We apply NeuroEvolution of Augmented Topologies (NEAT) to evolve adaptive and efficient swarm foraging behaviors in unknown environments with randomly placed obstacles. By rewarding effective actions and penalizing inefficient ones using the proposed strategy P-NeatFA, the training generates efficient foraging and obstacle avoidance strategies, reducing redundancy and outperforming traditional stochastic foraging algorithms. Optimization is guided by cumulative reward-based fitness, evaluated through simulations involving three types of distributed resources. Foraging performance is assessed in terms of resource retrieval rates. We compare the performance of our proposed P-NeatFA with that of CPFA and NeatFA. Experimental results show that P-NeatFA significantly outperforms the …

Mathematics, Physics, and Computer Science Faculty Articles and Research

Hydrometeorological teleconnections are key drivers of hydrological processes, representing the influence of large-scale atmospheric circulation patterns on regional climates. Understanding these teleconnections provides crucial insights into the mechanisms underlying hydrometeorological phenomena, particularly hydrological switches—rapid transitions between extreme events such as droughts and floods. These switches have become increasingly prevalent across the contiguous United States (CONUS), fueled by climate variability and evolving atmospheric patterns. This study utilizes cross-wavelet transform analysis to examine the spatial and temporal dynamics of hydrological switches and their correlations with major teleconnection indices, including NAO, ONI, WP, PDO, PNA, and QBO. The findings indicate significant coherence between …

Does Teach Lead To More Teachers? Evaluating The Effects Of The Federal Teach Program, Daniel Sparks

Counseling, Leadership, and Research Methods Faculty Publications and Presentations

Teachers are critical to education production. Yet, recruiting and retaining teachers has remained challenging, particularly in high need fields, at schools serving a high proportion of students from low-income backgrounds, and from racially diverse backgrounds. To incentivize enrollment in teacher preparation programs and to support teacher candidates through degree completion, the federal government implemented the Teacher Education Assistance for College and Higher Education (TEACH) Grant in 2008. The TEACH Grant offers undergraduate and graduate students up to $16,000 and $8,000 in grant aid, respectively, to pursue degrees in high need teaching fields. I use difference-in-differences analyses to estimate the effects …

Multi-Theoretic Perspective Of Backer Decision-Making In Crowdfunding: Interplay Of Backer, Founder And Ai, Maliha Alam

Theses and Dissertations

Crowdfunding has become a transformative mechanism for financing innovation, connecting creators directly with backers while bypassing traditional funding barriers. Despite its rapid global growth, only about 33.7% of campaigns succeed, largely due to ineffective communication of value propositions and lack of backer engagement. This dissertation investigates the complex interplay between project founders, backers, and emerging AI technologies to understand the factors influencing donation intention and to enhance crowdfunding success prediction.

Adopting the behavioral decision-making framework, I draw on multiple theoretical perspectives- signaling theory, the dual-process model of persuasion, and the cognitive-affective trust framework to examine founder- backer interactions. Using a …

Analyzing How Taste And Nutrition Impact Learning And Memory In Honey Bees Through Olfactory Associative Conditioning, Alessandra Elizabeth Perry

Theses and Dissertations

Honey bees detect sweet nectar, but not all sweet-tasting sugars provide nutrition. Unlike fruit flies, which can learn to avoid non-nutritious sweet foods, bees may lack this ability. To test if bees form caloric frustration memory (CFM), we conditioned them using odors paired with L-glucose (sweet but non-nutritious) or D-glucose (sweet and nutritious). Bees rewarded with L-glucose showed lower learning and long-term memory compared to D-glucose. Bees cannot differentiate between an odor associated with rewards containing malaise-causing compounds and an odor associated with a reward alone during differential conditioning. Therefore, we used differential conditioning to determine if lower acquisition in …

The Abduction Of Juan Manuel Fangio And Its Impact On The Cuban Revolution, Shalom Nissi Ramirez

Theses and Dissertations

On February 23, 1958, Juan Manuel Fangio, the five-time Formula One Champion, was kidnapped by the 26th of July Movement (M-26) in Havana, Cuba, during the Cuban Revolution. The kidnapping took place on the eve of the Havana Grand Prix as an act of sabotage against Fulgencio Batista's government. Fangio's abduction became a symbol of political resistance, challenging Batista's authority and raising the profile of M-26 as a revolutionary group. This thesis examines how the incident, amplified by worldwide media coverage, influenced international perceptions of the Cuban Revolution. It argues that using Fangio’s fame strategically helped accelerate awareness of the …

High Flying Adored: How Ceo Narcissism Influences Firms’ Responses To Above-Aspiration Performance With Risky Organizational Change, Korcan Kavusan, Daniel Mack, Matthew P. Mount, Gokhan Ertug

Research Collection Lee Kong Chian School Of Business

Research Summary: Research on performance feedback presents conflicting views on how above-aspiration performance influences organizational change. Some studies argue that it constrains change due to a lack of organizational motivation, while others suggest that it enables change by expanding managerial discretion. Reconciling these perspectives, we suggest that managers’ narcissistic tendencies can fundamentally alter how a firm responds to above-aspiration performance. We theorize and find evidence that high-narcissism CEOs respond to above-aspiration performance with more acquisitions—attention-generating actions that align with their self-enhancement motives, while under similar conditions low-narcissism CEOs avoid acquisitions, due to their uncertainty and risk. Our findings highlight the …

Collaboration In Action: An Exploration Of Collaborative Practice-Based Learning In Perservice Teacher Coursework, Logan W. Qualls

All Dissertations

New teachers report not feeling prepared to effectively collaborate with other professionals and families; however, collaboration is a large component of their day-to-day work. Thus, there is a need for teacher preparation programs to incorporate instructional methods that provide preservice teachers with opportunities to not only learn about the concept of collaboration but also to put those skills into place prior to entering the classroom. One possible answer to this need is to incorporate practice-based learning. Practice-based learning has been shown to effectively increase skill implementation for instructional and behavior management strategies; however, there is a lack of research regarding …

Chemical & Electromagnetic Signatures Of Binary Neutron Star Mergers, Benjamin Amend

All Dissertations

Binary neutron star (BNS) mergers are some of the most energetic events in the universe, producing both short gamma-ray bursts (GRBs) and kilonovae. GRBs are brief, bright flashes of gamma rays, powered by ultra-relativistic jets launched during the merger. These jets produce a prompt burst of gamma rays, followed by a broadband afterglow generated by external shocks as the outflow interacts with the surrounding medium. Kilonovae are optical-infrared transients from the radioactive decay of heavy, neutron-rich nuclei formed through the rapid neutron capture process (r-process) in the merger ejecta. Together, GRBs and kilonovae provide unique laboratories for probing fundamental physics …

Accurate online inertia estimation is essential for maintaining system reliability under these evolving conditions. This paper introduces a robust methodology for online inertia estimation using ambient data collected during normal system operation. The proposed method employs a state-space model to represent system dynamics and introduces synthetic step changes to simulate disturbances. By analyzing the frequency response and applying advanced signal processing techniques, the methodology estimates system inertia without requiring real large-scale disturbances. The approach is …

Resilient Control Framework For Ev Motor Drive System Subject To Cyber-Physical Security, Ali Arsalan

All Dissertations

The electric drive system (EDS) in electric vehicles (EVs) is one of the key safety-critical components. As IoT-enabled communication infrastructure for modern cyber-physical automotive systems continues to evolve, the importance of securing EDS against cyber threats along with physical faults, has become increasingly prominent. Among physical faults, power switches are particularly vulnerable and exhibit the highest susceptibility to open-circuit faults (OCFs). A compromised EDS, whether due to cyber threats or physical issues, can lead to excessive mechanical vibrations, increased thermal stress, fluctuations in electromagnetic torque, and elevated total harmonic distortion. These factors can substantially undermine traction control stability and jeopardize …

Using Parent Empowerment Groups To Increase Academic Success In Kindergarten Multilingual Learners, Sarah C. Deloach

All Dissertations

This study examined how parent empowerment groups influence the academic success of kindergarten multilingual learners. With increasing immigration across the United States, schools need to work with families to ensure students develop the skills required for academic achievement at each level. The identified problem is that the current multilingual learner program at Boyd Matthews Elementary does not adequately meet parents’ needs in building a strong home-school connection, placing the full responsibility of learning on the school and leaving students without critical academic support at home. Parent empowerment groups were held with multilingual kindergarten parents to share practical strategies for supporting …

The Influence Of Past Experiences On Middle School Band Directors’ Instructional Practices, Jessie Lynn Peterson

All Dissertations

This qualitative study investigated the influence of middle school band directors’ past experiences on their instructional decision-making and implementation of culturally relevant pedagogy (CRP). Embedded in Ladson-Billings’s (1995, 2014) CRP framework and Lortie’s (1975) apprenticeship of observation theory, this study explored the relationship between middle school band directors’ past experiences, their beliefs about CRP, and their instructional practices.

Music education in the United States has historically focused on Western European classical traditions that overlook the cultural diversity of today’s students and reinforce dominant pedagogical norms. Semi-structured interviews were conducted with six middle school band directors. Participants discussed their musical backgrounds, …

Designing Self-Healable Aromatic Copolymers And Olefinic Composites, Samruddhi Yashwant Gaikwad

All Dissertations

Self-healing polymers capable of recovering from mechanical damage are promising materials for advanced applications, especially those involving mechanical and/or physical fatigue. In these studies, we have developed techniques to achieve autonomous self-healing in commodity Styrene/n-butyl acrylate copolymers. The mechanism of self-healing in the designed polymers involves inter-and/or intrachain non-covalent interactions between π-cloud and polar linkages of acrylic nBA in random/preferentially alternating copolymers. A combination of spectroscopic tools, thermo-mechanical analysis, and molecular dynamics (MD) simulations has been used to elucidate the mechanism of self-healing. These studies further show the incorporation of dipolar C-F groups to understand the effect of having fluorinated …

Like Footprints In The Sand: How Founders Imprint Organizational Culture Through Nonverbal Cue Signaling, Dirk M. Roskam

All Dissertations

Despite growing recognition of the significance of founders’ behaviors in shaping organizational culture, limited research has explored how founders’ non-verbal cues (NVCs) imprint culture during a venture’s formative stages. This qualitative case study examines how a founder’s NVCs, ranging from physical environment design to gestures and demeanor, are interpreted by employees and contribute to the imprinting of organizational culture. Drawing on imprinting theory, signaling theory, and the Organizational Culture Profile (OCP), the study triangulates data from semi-structured interviews, a focus group, and a literature review. Findings reveal that employees interpret 24 salient NVCs, grouped into themes of environmental values, people-centric …

Toward A Unified Theory Of Fire-Induced Spalling Of Concrete: Transcending Domain Knowledge Limitations Through Explainable Artificial Intelligence, Causal Discovery And Inference, Mohammad Al Bashiti

All Dissertations

When concrete is exposed to fire, it can suddenly break apart in a dangerous process called spalling. This can severely weaken buildings and even trigger a collapse. While researchers have studied this problem for years, we still don’t fully understand what causes it. My research uses a combination of data, and advanced AI techniques to identify and quantify the key factors that increase the risk of spalling. I collected data from over 1,000 fire tests and used AI models to predict when spalling might happen. I also applied explainable AI tools to understand why it happens.

The results showed that …
