SlideSAVR: Enabling Live Analysis during Data Presentations via Multimodal Sketching and Voice Input

Computer Graphics Forum, EarlyView.
Abstract Interpersonal communication in data science can yield sought‐after insights, but presentation environments are often not conducive for live analysis, forcing the process to move offline. Through a formative survey with 16 participants, we identified both technical (e.g., complexity of tools) and psychological (e.g., pressure of programming ...

National Relics: Secular Sacrality, Museums, and Heritage‐Making in Nineteenth‐Century Chile

Museum Anthropology, Volume 49, Issue 2, Fall 2026.
ABSTRACT This article examines how objects and bodily remains are transformed and ritualized into national relics through collecting and exhibiting practices in museums. Focusing on nineteenth‐century Chile, it draws on archival sources, material culture theory, and the anthropology of religion to argue that objects associated with Chile's nation‐state
