The Bleeding Edge Of Misogyny: How Gender-Based Harassment And Infrastructural Neglect Shape Menstrual Distress, Mackenzie J. Miller Jan 2026

The Bleeding Edge Of Misogyny: How Gender-Based Harassment And Infrastructural Neglect Shape Menstrual Distress, Mackenzie J. Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite growing attention to menstrual health, organizational research has largely overlooked how workplace conditions shape menstrual experiences. Dominant perspectives frame menstruation as an individual issue that negatively affects work, neglecting how features of the work environment – such as gender-based harassment and access to menstrual-related infrastructure – contribute to menstrual distress. Addressing this gap, this dissertation adopts a bidirectional perspective, examining how social and material workplace conditions shape menstrual distress, defined as the extent to which menstrual symptoms interfere with daily functioning. Drawing on the transactional model of stress and objectification theory, I hypothesized that gender-based harassment would predict menstrual …

This complex contains C. bulbosa, C. macrantha, and C. mertensiana, the latter with three varieties (maculata, occidentalis, and mexicana). These taxa vary in flowering time, floral morphology, and fungal associations. However, the degree …


A Multiobjective Framework For Joint Coverage And Motion Planning In Uav Inspection Tasks, Luis Fernando Escobar Carvajal Jan 2026

A Multiobjective Framework For Joint Coverage And Motion Planning In Uav Inspection Tasks, Luis Fernando Escobar Carvajal

Graduate Theses, Dissertations, and Problem Reports (ETD)

Unmanned Aerial Vehicles (UAVs) have become essential for data acquisition in complex 3D environments. However, traditional Coverage Path Planning (CPP) methodologies often rely on a sequential pipeline that isolates viewpoint generation from flight path routing. This decoupling fails to account for the interdependence between viewpoint distribution and minimum flight paths, effectively restricting the search space and preventing the identification of a global optimum. This dissertation proposes a unified multi-objective framework for joint coverage and motion planning. The primary contribution of this work is the transition from isolated, sequential steps to a simultaneous optimization of the number and position of viewpoints …

Dispositional Mindfulness And Autonomic Reactivity, Thomas Dylan Boyer Jan 2026

Dispositional Mindfulness And Autonomic Reactivity, Thomas Dylan Boyer

Graduate Theses, Dissertations, and Problem Reports (ETD)

To explain how different facets of mindfulness were associated with task performance in distinctive ways, Lindsay and Creswell (2017) proposed the Monitor and Acceptance Theory (MAT). According to this model, the mindfulness facet of monitoring present state awareness was thought to influence task performance differently than the nonjudgmental acceptance facet of mindfulness, but no studies to date have examined this model with respect to an individual's physiological response to stressful tasks. Because dispositional mindfulness has been associated with both increased and decreased physiological and affective reactions to stress in previous studies, the present study tested whether the Monitoring facet of …

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, violence has risen to record-high numbers in communities and correctional facilities, with men perpetrating the vast majority of violent crimes. Hypermasculine values (e.g., power, aggression, and domination) have been linked to aggressive and violent behavior. Hostile attribution bias, which leads individuals to attribute hostile intent to neutral or ambiguous stimuli, has also been linked to aggression.

The current study used structural equation modeling (SEM) to examine hypermasculinity and hostile attribution bias as predictors of proclivity for violence, comprised of aggression and historical violence. The model was iteratively modified to assess changes in model fit and constructs. Male …


Statistical Analysis Of Evidence In Criminal Cases, Giuliana Leon Carrillo Jan 2026

Statistical Analysis Of Evidence In Criminal Cases, Giuliana Leon Carrillo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ideally, the evaluation of relevant forensic evidence must corroborate the hypotheses that the prosecution and/or the defense holds regarding the commitment of a crime. Therefore, optimal forensic evidence would be the one that can be found all the time under the same circumstances, and cannot be found otherwise, making the forensic scientist able to evaluate this evidence given the hypotheses provided. Nevertheless, this is hard to find, as ideal evidence being only a concept.

In this project, the probabilistic interpretation of relevant forensic evidence investigated in criminal cases with the aid of Wigmore charts and Bayesian networks was proposed. Using …
