From Essays To Embodiment: Reimagining Student-Centered Assessment Through Creative Practice, Rory Bester, Carla Lever, Bongani Kona, Mona Hakimi

Turning Toward Being: The Journal of Ontological Inquiry in Education

This essay explores the experience of implementing podcast-based assessment in ‘Feeling History, Making History,’ a semester-long course at the University of the Western Cape (UWC) in South Africa. The course is designed to cultivate broad-based critical and interdisciplinary skill sets in first-year Humanities students. Through pedagogical reflection across three consecutive iterations of this course, we investigate how creative assessment practices such as podcasting both enabled our students to bring their whole “selves” into the academy and productively challenged our own preconceived notions about effective, decolonial pedagogy.

“The Being Of Being Creative” In Assessment: Learning From The Creative And Performing Arts, Eliana Elkhoury

Turning Toward Being: The Journal of Ontological Inquiry in Education

Assessment design shapes not only what students learn, but who they become as learners. In the era of generative artificial intelligence (GenAI), where information is abundant and recall is easily outsourced, higher education assessment must move beyond memorization and toward authentic tasks that cultivate deeper learning and ontological growth. This conceptual, reflective paper argues that assessment should be grounded in students’ mode of being, rather than restricted to knowing, having, or doing. Drawing on Barnett’s ontology of higher education, Biesta’s subjectification, and Su’s epistemological distinctions, this paper positions assessment as a formative site where agency, ownership, identity, and self-understanding can …

The purpose of the study was to examine unforeseen consequences of Proposition 12, with attention to its direct and indirect impacts on animal welfare, farmers, and low-income …

Predictive Modeling Of Hematoma Expansion From Non-Contrast Computed Tomography In Spontaneous Intracerebral Hemorrhage Patients, Natasha Ironside, Shinjini Kundu, Et Al.

2020-Current year OA Pubs

Hematoma expansion is a consistent predictor of poor neurological outcome and mortality after spontaneous intracerebral hemorrhage (ICH). An incomplete understanding of its biophysiology has limited early preventative intervention. Transport-based morphometry (TBM) is a mathematical modeling technique that uses a physically meaningful metric to quantify and visualize discriminating image features that are not readily perceptible to the human eye. We hypothesized that TBM could discover relationships between hematoma morphology on initial Non-Contrast Computed Tomography (NCCT) and hematoma expansion. 170 spontaneous ICH patients enrolled in the multi-center international Virtual International Trials of Stroke Archive (VISTA-ICH) with time-series NCCT data were used for …

Killing Like A State: Explaining The Edge Cases Of Rebel Perpetration Of Wartime Genocidal Violence, Cheng Xu

Government: Faculty Publications

Genocide scholarship overwhelmingly identifies states as the primary perpetrators of genocidal violence. While non-state armed groups, particularly pro-government militias, have been implicated in genocide, rebel-perpetrated wartime genocidal violence remains exceedingly rare. This paper argues that state-centric explanations of genocide can be exported to explain these edge cases. I argue that four high-threshold conditions must align for rebels to commit wartime genocidal violence: (1) effective territorial control, (2) the dispensability of civilian support, (3) a rigid and exclusionary ideological program, and (4) perceptions of threat, typically constitutive rather than military, where the target group is framed as incompatible with the nascent …

Latent Action Trajectory Optimization, Rahul Milind Kandekar

Master's Theses

Learning from demonstrations offers a path to bypass the sample inefficiency of reinforcement learning, but obtaining action-labeled expert demonstrations remains expensive and often impractical. Learning from Observations (LFO) addresses this by learning policies from observation-only demonstrations. Recent LFO work relies heavily on behavior cloning: VPT and LAPO use observation-only data combined with limited action labels to train BC policies, while AIME offers an alternative policy inference approach but requires the majority of its training data to have action labels. Through systematic experiments in the Lunar Lander environment, we investigate whether latent action methods can function when state and action dimensionalities …

Design Of An Fsae Muffler, Suzy Schwabl

Mechanical Engineering and Materials Science Independent Study

To compete in the dynamic events at the the Formula SAE IC competition, each vehicle must undergo a rigorous technical inspection. One element of the inspection is the Noise Test, which states that each car must be quieter than 103 dBc when idling and less than 110 dBc at the engine redline. Over the past few years, WashU Racing has used off-the-shelf mufflers with a guess and check system to find muffler combinations that satisfy the noise requirement. The results of that method have yielded either heavy and performance damaging muffler configurations or mufflers that have failed to meet the …
