Power and Politics in the Media: The Year in C-SPAN Archives Research, Volume 9

Power and Politics in the Media: The Year in C-SPAN Archives Research, Volume 9 features articles from multiple disciplines that use the C-SPAN Video Library to explore recent controversies in American politics. Topics covered include Supreme Court nominations, Supreme Court oral arguments, rhetoric on disasters and COVID-19, and the effect of clothing on the approval of women in power. What unites these topics is the unique use of the video record of C-SPAN to explore the intersections of politics, power, rhetoric, and the media in the contemporary United States. Written in accessible prose, this volume showcases some of the most pressing issues today in a variety of political and communication issues while demonstrating video research methodologies

Tracking the Temporal-Evolution of Supernova Bubbles in Numerical Simulations

The study of low-dimensional, noisy manifolds embedded in a higher dimensional space has been extremely useful in many applications, from the chemical analysis of multi-phase flows to simulations of galactic mergers. Building a probabilistic model of the manifolds has helped in describing their essential properties and how they vary in space. However, when the manifold is evolving through time, a joint spatio-temporal modelling is needed, in order to fully comprehend its nature. We propose a first-order Markovian process that propagates the spatial probabilistic model of a manifold at fixed time, to its adjacent temporal stages. The proposed methodology is demonstrated using a particle simulation of an interacting dwarf galaxy to describe the evolution of a cavity generated by a Supernov
