Indeed, In A Way, It's Worse., Jani C. Zubkovs

Theses and Dissertations

This thesis investigates walking as both method and metaphor within an artistic practice grounded in photography. Through walking, I engage in a sustained act of seeing — one that resists the speed and consumption-driven logic of late capitalism and opens space for reflection, slowness, and heightened perception. My photographic work focuses on fragments of the built environment, particularly advertisements, signage, and residual human marks, reframing them through strategies of cropping, isolation, and recontextualization. These images question the distinction between original and reproduction, presence and absence, surface and depth. Drawing on thinkers such as Jonathan Crary, Luigi Ghirri, Siegfried Kracauer, and …

Dynamic Approaches To Missing Data In Healthcare: Evaluating Ensemble Models, Feature Selection, And Meta-Features, Dylan Dominguez Sulca

Theses and Dissertations

Missing data is pervasive in healthcare, where incomplete observations commonly arise from patient dropout, sensor failures, or privacy constraints. This research presents an investigation into handling such data, focusing on (1) Missingness-Aware Dynamic Ensemble Weighting (MDEW), (2) feature selection under varying missing rates, (3) autoencoder-based imputation (ODAE), and (4) a meta-feature analysis guiding pipeline selection. We evaluate our experiments on four diverse datasets, Cleveland Heart Disease, Diabetic Retinopathy, Breast Cancer Wisconsin, EEG Eye State. Our research shows that MDEW adaptively selects imputer classifier pipelines, outperforming single model and uniform averaging baselines at moderate to high missingness 10% to 50%. Filter …

Examining Components Of The Interpersonal Psychological Theory Of Suicide In A Clinical Sample Of Children With Suicidal Thoughts And Behaviors, Alana Brixner Nunes

Theses and Dissertations

Suicide is the second leading cause of death among 10- to 14-year-olds. Despite a need to identify risk factors for suicide among children, there is limited research on suicidal thoughts and behaviors (STBs) in childhood. The interpersonal psychological theory of suicide (IPTS) suggests that the desire for suicide emerges from perceived burdensomeness and thwarted belongingness and that the transition from suicide ideation (SI) to a suicide attempt (SA) results from an acquired capability for suicide. However, no research has examined whether the IPTS applies to suicidal thoughts and behaviors among children. The present research examined components of the IPTS in …
