C-SPAN is the network of record for US political affairs, broadcasting live gavel-to-gavel proceedings of the House of Representatives and the Senate, and to other forums where public policy is discussed, debated, and decided--without editing, commentary, or analysis and with a balanced presentation of points of view. C-SPAN Video Library, adjacent to Purdue University, archives copies of all broadcast content, including policymaking proceedings, events, discussion, and debate, aired on the C-SPAN network since 1987. Extensive indexing, captioning, and other enhanced online features provide researchers, policy analysts, students, teachers, and public officials with an unparalleled chronological and internally cross-referenced record for deeper study.C-SPAN Insights presents the finest interdisciplinary research utilizing tools of the C-SPAN Video Library. Each volume highlights recent scholarship and comprises leading experts and emerging voices in political science, journalism, psychology, computer science, communication, and a variety of other disciplines. Each section within each volume includes responses from expert discussants. Developed in partnership with the Brian Lamb School of Communication and with support from the C-SPAN Education Foundation, C-SPAN Insights is guided by the ideal that all experimental outcomes, including those from our American experiment, can be best improved by directed study driving richer engagement and better understanding. C-SPAN Insights-Volume 4, edited by Robert X. Browning, advances our understanding of the framing of mental health, HIV/AIDS, policing, and public health, and explores subjects such as audience reactions in C-SPAN covered debates, the Twitter presidency of Donald Trump, and collaborative learning using the C-SPAN Video Library.
