An adjunct member of Penn College's history faculty offered an absorbing look at technology and propaganda on Oct. 6 in the first presentation of the Daniel J. Doyle Technology & Society Colloquia Series. In “From the Nazis to ISIS: A Historical Analysis of Technology and Propaganda,” Katrina A. Sinclair drew a parallel between the Nazis' convincing use of broadcast venues and the Islamic State's embrace of social media in recruiting and rallying their respective followers. While the subject matter raises difficult questions and provocative conversation, she said, it points to the importance of open dialogue – a discussion she hopes will develop proactive strategies to counter extreme ideologies in our global society. The next event in the series will be held at 7 p.m. Tuesday, Nov. 3, when Alan R. Neuner, vice president for facilities operations at Geisinger Medical Center, presents “Improving National Health Through Energy Efficiency.” Sinclair's full presentation can be seen on the college's YouTube Channel:http://www.youtube.com/watch?v=F4mj_macM_w
