How School Psychologists Narrow The Socioeconomic Opportunity Gap: The Practices And Beliefs Of School Psychologists In High-Performing, High-Poverty Schools, Nora Durgin

Dissertations

The purpose of this study is to examine the practices and beliefs of school psychologists working in high-performing, high-poverty (HP/HP) schools in order to make recommendations for how their practices can be replicated in other high-poverty schools to help narrow the socioeconomic opportunity gap. Results indicate that school psychologists engage in the major professional activities of school psychology practice to a similar degree as is documented in the existing literature. Despite relatively lower levels of engagement in delivering mental and behavioral health services, school psychologists view the practice to be highly impactful on students’ academic achievement. The school-wide activities commonly …

Philosophical Purification As Liberation And Transformation, Lachanda C. Davis

Dissertations

This study utilizes Plato’s conception of purification as a diagnostic tool to examine contemporary issues of police brutality and political violence. Within this context, I aim to treat the multiple tensions that arise with the question of living a good life. What does it mean to live and what does it mean to live a good life within constraints that magnify fear, anxiety, and despair? I argue that philosophical purification involves ‘aporia’ (perplexity; difficulty; confusion; loss; or puzzlement) in both a literal and generative sense. Moreover, the multiple aporias that arise cannot be reconciled by merely performing a religious rite …

Well-being was assessed through life satisfaction, negative affect, and …

Drawing The Curtain: A Grounded Theory Analysis Of The Conceptualizations Of Culture, Ethnicity And Race In Professional Training Materials For Child Life Certification, Kia Lee Ferrer

Dissertations

Objectives: Certified Child Life Specialists (CCLS) are pediatric healthcare professionals primarily working in hospital settings to support children and families in navigating the developmental challenges of hospitalization, illness, and enduring medical treatment. Recognizing the presence of racial and ethnic health disparities, coupled with the field’s notable lack of diversity (98% White female), the child life workforce is increasingly acknowledging the undeniable evidence that discriminatory behaviors adversely affect a child’s life and well-being. As advances in the social sciences increasingly reveal that discrimination functions as a "socially transmitted disease" in a child's life, I predict that the failure of child life …

The Beloved Disciple In Performance, Eric Christian Zito

Dissertations

This project aims to reconsider the Fourth Gospel’s Beloved Disciple from the standpoint of biblical performance criticism, an approach that takes seriously the likelihood that most first-century audiences would have encountered the Fourth Gospel by means of performance rather than private reading. The dissertation considers: 1) what difference the medium makes in a first-century reception of John’s Gospel, and 2) how early audiences would have been shaped by the discipleship model portrayed by the unnamed Beloved Disciple in a performance setting. Against the current of mainstream scholarship, I argue that the Beloved Disciple is a developing character who epitomizes Johannine …

Parental Autonomy Support And Children’S Affect As Predictors Of Children’S Stem Engagement In An Informal Educational Context, Bianca Martins Aldrich

We characterized children’s affect in terms of valence (positive or negative) and activation (activating or deactivating), and parental talk was characterized as autonomy supportive or directive, as well as STEM-related or not. Parents and their 4- to 10-year-old children were recruited at the entrance of the Tinkering Lab exhibit at Chicago Children’s Museum. Parents and children were video and audio recorded during the activity. We coded parents’ and children’s behaviors using a time-sampling …

Fear Of Victimization, Trust, Security, And Public Spaces In Guatemala, Keyla Navarrete

Dissertations

This dissertation explores fear of victimization, personal encounters with crime, perceptions of institutional trust, support for informal justice practices, and avoidance of spaces in Guatemala. Institutional trust—understood as individuals’ confidence in the police, judiciary, and correctional systems, particularly their fairness and effectiveness—is vital for democratic governance and social stability. High levels of trust in legal institutions can foster civic engagement, reduce social fragmentation, and encourage public cooperation in crime prevention. In contrast, diminished trust may lead individuals to withdraw from formal systems of justice, limiting the state's capacity to function effectively. Utilizing nationally representative data from the National Survey of …

Forgive As We Are Forgiven: Reframing A Trinitarian Model Of Forgiveness In A Post-Genocide Rwanda, Deogratias Mbonyumugenzi

Dissertations

This dissertation seeks to develop a theological model of forgiveness rooted in a relational conception of the Trinity. The central argument of this dissertation is that the model of forgiveness practiced in post-genocide Rwanda and the forgiveness modeled by Jesus, and testified to in the New Testament and developed in the Christian tradition, are good, but not sufficient to address the kind of trauma and human disrepair, as well as the devastation of communities, inflicted by genocide. Rather, a theology of forgiveness modeled on a relational conception of the Trinity and its practical implications for a Trinitarian ecclesiology and anthropology …

The Global Phase Space Of The Three-Vortex Interaction System And Its Application To Vortex-Dipole Scattering, Atul Anurag

Dissertations

This dissertation presents a global reduction of the classical three-vortex problem that is free from coordinate singularities, enabling a comprehensive analysis of the system's dynamics across all circulation regimes.

To achieve this, a two-step symplectic reduction procedure is developed. The first step introduces Jacobi coordinates adapted to the symplectic structure of the vortex system, and the second applies a Lie-Poisson reduction to the resulting system. This formulation eliminates the non-physical singularities associated with collinear vortex configurations and facilitates a global phase space analysis, including a detailed and novel investigation of bifurcations.

Within this reduced framework, all relative fixed points are …

Reduced Order Models Of Hydrodynamically Interacting Flapping Wings, Jose Pabon

Dissertations

Fish schools exhibit a collective behavior and self-organization that is mediated by hydrodynamic interactions between individual fish. However, the long-time evolution of hydrodynamically interacting collectives is challenging to investigate due to the persistent influence of long-lived vortical structures, and the high-resolution requirements of direct numerical simulation at large Reynolds numbers. Reduced-order models have therefore played an important role in theoretical investigations of collectives of swimming bodies. The main results detailed herein are several new reduced-order models of swimmers that self-propel by flapping, i.e., by executing a prescribed periodic rigid body motion. The models are extensions of a discrete-time dynamical system …
