Carleman Linearization Of Dynamical Systems, And Graph Inverse And Wiener Filtering, Cong Zheng

Graduate Thesis and Dissertation post-2024

Carleman linearization is a mainstream approach for transforming finite-dimensional nonlinear dynamical systems into infinite-dimensional linear systems. It provides accurate approximations of the original nonlinear system over larger regions around the equilibrium for longer time horizons, surpassing the capabilities of conventional first-order linearization. In Chapter 1, we derive explicit error bounds for the finite-section approximation, demonstrating its exponential convergence concerning the finite-section order. We illustrate that for a specific class of nonlinear systems, exponential convergence can be achieved across the entire time horizon, extending to infinity. These results hold significant practical utility, as the proposed error bounds can be used to …

Motion Extrapolation And Motion Dynamics: Are The Motion Dynamics Of Friction Utilized During Motion Extrapolation To Inform Time-To-Contact Estimations?, Genna Telschow

Graduate Thesis and Dissertation post-2024

Cognitive processing delays should cause us to respond too late when making time-to-contact estimations. According to the theory of constructivism, the brain accounts for these delays by supplementing sensory information with higher level cognitive information to create an accurate motion percept. Across the attention, memory, and motion extrapolation literatures there is evidence supporting the use of higher-level information, like motion dynamics, to supplement our visual input. Specifically, previous research suggests we may account for friction’s constraints on motion when interacting with dynamic stimuli. The current research utilizes features that represent friction as both a stopping agent and a motion catalyst …

The Impact Of Virtual Backgrounds In Video-Mediated Selection And The Role Of Candidate Qualifications, Mira Gruber

Graduate Thesis and Dissertation post-2024

Videoconferencing allows users to manage their self-presentation through virtual backgrounds that mask their immediate physical environment. Prior research suggests that backgrounds depicting professional home spaces (e.g., bookshelves) elicit more favorable impressions than those that depict personal home spaces (e.g., bedrooms). Expectancy Violations Theory (EVT) provides a framework for understanding such effects. The present dissertation applied EVT to video-mediated selection interviews, that have become increasingly popular since the COVID-19 pandemic. Given the strict expectations for professionalism in interviews, virtual backgrounds that deviate from such expectations may negatively impact hiring decisions. Consequently, this work examined the impact of two virtual background types, …

The Dual Dynamics Of Succession: Unveiling The Interplay Among The Former Leader, The New Leader, And Followers' Implicit Theories Of Leadership On Subsequent Leader Evaluations, Emily Hill

Graduate Thesis and Dissertation post-2024

Leader succession is the planned or unplanned change in formal leadership at an organization. Ample research has investigated the effects of leader succession at higher levels of leadership on team and organizational performance, yet little is known about the effects of leadership changes at lower levels of management on followers’ reactions to their new leader. Drawing on cognitive appraisal theory (Lazarus & Folkman, 1984) and contrast effect theory (Markman & McMullen, 2003), this dissertation empirically tested a model in which the congruence of followers’ implicit theories of leadership with characteristics of the new leader were expected to influence three leader-related …

Parents’ Adverse Childhood Experiences And Young Children’S Behavior Problems: Examining Protective Moderating And Mediating Factors, Kaitlyn M. Daleandro

Graduate Thesis and Dissertation post-2024

Adverse childhood experiences (ACEs) are childhood exposures to abuse, neglect, and household dysfunction. ACEs have been linked to a cumulative negative impact on later adult physical and psychological well-being. Parents who carry ACEs often have difficulties in parenting, which have, in turn, been linked to young children’s internalizing and externalizing behavior problems. Nonetheless, some parents who carry ACEs develop positive parenting strategies. Very little is known about how such outcomes occur. A growing area of research concerns protective and compensatory experiences (PACEs) that buffer against the negative consequences of ACEs. PACEs may improve deficits in cognitive, emotional, and neurobiological systems …

Sexual And Gender Minority Identity Acceptance And The Role Of Florida Legislation Perception On Medical Disclosure And Risky Health Behaviors, Aubrianna L. Stuckey

Graduate Thesis and Dissertation post-2024

Recently, across the United States, efforts have been made to remove protective legislation and resources surrounding the sexual gender minority (SGM) community (Woodford et al., 2018). Given how quickly Florida’s HB 1557 legislation was passed and the corresponding, ongoing attempts to expand the bills, there is limited research exploring the role of legislative change on SGM communities. Newer literature indicates that discriminatory laws or bills have impacted the mental health of the SGM community, especially among SGM adolescent and young adults ; however, research exploring the role legislation has on SGM individual’s physical health, requires further investigation(American Psychological Association, 2023; …

Quality Of Service Robots And Organizational Citizenship Behaviors: The Mediating Roles Of State Empathy And Perceived Organizational Support/Obstruction, Adam D. Jacobs

Graduate Thesis and Dissertation post-2024

Research on service robots is currently more conceptual than it is empirical. This thesis leverages resource allocation and social exchange theories to explain how employees choose to expend their resources depending on the functioning of the service robot. I propose that service robot quality (defined here as an employee’s perception of the usefulness and ease of use of a service robot) is an important consideration for organizations that adopt service robots, and hypothesize that employee state empathy and support (or obstruction) from their organization links service robot quality to employee organizational citizenship behaviors. The study consisted of 166 participants from …
