From Pencil To Pixel: How Leadership Shapes Organizational Responses To Competence-Destroying Technological Change, Jennifer Underwood

All Dissertations

This dissertation examines how managerial leadership enables organizations to overcome inertia during competence-destroying technological change through a historical comparative case analysis of the animation industry's transition from hand-drawn to computer-generated imagery (CGI) between 1980-2000. Drawing on archival data from Disney, Pixar, and Don Bluth Studios, I identify three distinct leadership approaches—pioneering, bridging, and preserving—that differently influenced how workforces adjusted their views of identity, process, and change. These adjustments led to three different outcomes: transformative integration, constrained adoption, and entrenched resistance. This research makes three theoretical contributions and develops a novel framework that explains how leadership can constrain or enable transformation, …

Exploring The Effects Of Remote Work On Leadership Pipelines: With A Focus On Professional Women And Minorities, Mark S. Andrekovich

All Dissertations

I analyzed data from five U.S.-based companies to understand how remote work models affect leadership advancement. Using Role Congruity, Status Characteristics, and Intersectionality theories, I analyzed five hypotheses about the impact of remote work on leadership pipelines. Two of the five hypotheses were supported, revealing bias patterns rather than issues related to remote work. For instance, white employees had greater access to remote work opportunities than non-white employees, who had fewer promotions despite similar performance scores. Contrary to expectations, I found that remote work does not inherently affect promotional advancements. Via a post hoc analysis, I found that hybrid professionals …

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 …

Accurate Temporal Integration Schemes For Nonlinear Adsorption Problems, Evan D. Butterworth

All Dissertations

We consider a nonlinear transport problem to model the chromatography process of high-capacity multimodal membranes. Robust and efficient algorithms that simulate these bioseparation processes are critical to developing therapeutics for various chronic illnesses and infectious diseases. However, much of the current methodology focuses on stabilization and linearization techniques, often implementing low-order time-discretizations and linearized adsorption, resulting in inefficiencies and inaccuracies in the numerical solution. Utilizing Rothe's method, we develop various time-discretization schemes coupled with the finite element method to solve the fully implicit problems. Stability and solvability results are presented for several methods. Through multiple high-level software implementations paired with …

Gesture-Based Icon Messages: Examining The Effects Of A Nonverbal Transparency Strategy For Supporting Situation Awareness In Human-Autonomy Communication, Heather Watkins

All Dissertations

Automated systems continue to transform tasks that were once manual, introducing new challenges for operators to maintain situation awareness (SA). This research examines gesture-based icon messages (GIMs) as a transparency strategy to address challenges present in human-autonomy communication (HAC). Drawing from Endsley’s (1995) three-level model of SA, GIMs were designed to convey different types of information: perception, comprehension, and projection. The goal of this work was to understand whether GIMs could be distinguished by operators, and whether they support SA under conditions that reflect the divided attention demands that are common in operational settings. Study 1 focused on assessing whether …

Structural Design Using Conditional-Gan Fused With Property Text Information: A Case For Masonry Structures, Arash Teymori Gharah Tapeh

All Dissertations

Structural design, by nature, is a complex process that requires a considerable amount of time, expertise, and knowledge. In such a process, the structural designer must navigate various codal provisions to crystallize a proper and adequate design. As the role of automation continues to shape the domain of structural engineering over the past few decades, a new front leverages artificial intelligence (AI). Currently, AI acts as a "copilot," collaborating to advance workflow speed and accelerate the design process. Among all the different collaborations between humans and AI, GANs (Generative Adversarial Networks) are seen to complement human creativity by automating specific …

The Dark Side Of Great Lmx Relationships: Why Your Best Employees Might Be Burning Out, Ryan Toole

All Dissertations

While workplace relationships are widely considered beneficial for employee well-being, a paradox emerges when employees with the strongest leader relationships experience burnout despite receiving excellent support. This contradiction suggests that these very same relationships may create psychological pressure to reciprocate support and result in employee burnout. Drawing on Social Exchange Theory and Conservation of Resources theory, I examine whether felt obligation resulting from Leader-Member Exchange (LMX) relationships contributes to employee burnout across the full spectrum of LMX quality relationships. I argue that LMX quality creates felt obligation to reciprocate leader support. This obligation, in turn, depletes emotional resources and leads …
