A Comparative Pentadic Analysis of Mediated Presidential Discourse During 9/11 and Hurricane KatrinaAljabri, Nadia Michele 12 June 2007 (has links)
In his first term as president, George W. Bush was confronted with one of the worst national attacks in United States history: the September 11 terrorist attacks of 2001. Through the devastation, however, President Bush triumphed in unifying and guiding this nation during what would become the height of his rhetorical leadership. Following his reelection in 2004, President Bush faced one of the worst natural disasters in the nation's history: Category 4 Hurricane Katrina. In its aftermath, Katrina became known as "one of the worst mishandled disasters ever." Utilizing Kenneth Burke's pentad, this study analyzes the president's rhetorical response and the primetime network news coverage following each crisis in an attempt to determine how President Bush could fare so well in one instance, consoling and leading the American people, while falling short in his second major crisis during his term as president. / Master of Arts

The Fourth Estate on Trial: Examining Partisan Bias in Broadcast and Cable News Coverage of the First Trump ImpeachmentMontgomery, Joshua Phillip 07 1900 (has links)
I examine partisan bias in broadcast and cable news coverage of the first impeachment of President Trump by evaluating how well three theories of news generation—network bias, marketplace incentives, and institutional forces—predict coverage, framing, and tonal biases. While no single theory provides a complete explanation of all partisan bias, institutional forces explain impeachment coverage better than either network bias or marketplace incentives. This research also highlights the nuanced nature of partisan frame representation, and suggests that institutional and marketplace theories better predict partisan frame diversity than theories of a partisan press. Finally, analysis of tonal bias reveals complex variations across and within news mediums, challenging simplistic narratives of network bias. My research shows that many of the professional norms and routines that have long been known to influence news generation continue to do so even as they evolve.

Voice Activity Detection / Voice Activity DetectionEnt, Petr January 2009 (has links)
Práce pojednává o využití support vector machines v detekci řečové aktivity. V první části jsou zkoumány různé druhy příznaků, jejich extrakce a zpracování a je nalezena jejich optimální kombinace, která podává nejlepší výsledky. Druhá část představuje samotný systém pro detekci řečové aktivity a ladění jeho parametrů. Nakonec jsou výsledky porovnány s dvěma dalšími systémy, založenými na odlišných principech. Pro testování a ladění byla použita ERT broadcast news databáze. Porovnání mezi systémy bylo pak provedeno na databázi z NIST06 Rich Test Evaluations.
