Evaluation of Rhetorical Situations

For this blog post I will choose three different texts that serve as examples of acts of opinionated public speech by someone in the field of science.  I will analyze the rhetorical situations (author/speaker, audience, and context) in the three sources that I will use.

Paul Thompson. "Fairbanks speaking in front of a crowd at a 1918 war bond drive in New York City". 16 November 2007 via Wikipedia Public Domain

	Author/Speaker	Audience	Context
Source 1	Richard Draijer, Young de Graaf, Marieke Slettenaar, Eric de Groot, and Chris I. Wright All authors are doctors (PhD) in the fields they study. Those fields include biology, physiology, and the medical field.	The primary audience is people that have background knowledge of science based around biology, physiology, and chemistry.  A secondary audience can be anyone that has interest in the benefits of red wine and how ingredients found in it provides health benefits to people who consume it. Also important to note, this article is extremely helpful for individuals that have high blood pressures and want to study information that can help their medical situation.	The journal article that is being used as this source was published in 2015.  The purpose of this article is to inform readers how the consumption of a nutrient found in grapes and wine lowers blood pressure for hypertensive individuals (people that have high blood pressure).
Source 2	Shlomo Cohen He is a professor of philosophy at Ben-Gurion University of the Negev, Beer-Sheva 84105, Israel	The audience is for people that have knowledge about cloning extinct species.  Along with these individuals, this article is written for people that interested in the ethics of having species becoming de-extinct.	The article was published in 2014.  The purpose of this article is to bring the ethics perspective to the idea of having extinct species coming back to life through biological technology.
Source 3	William Glen He was a former editor at Stanford University Press, a former scientist and historian at the U.S. Geological Survey, Menlo Park.	The audience for this article can include people that have knowledge about scientific topics, and any person that has a particular interest about the extinction of dinosaurs.	The article was published in 1990 from the magazine, American Scientist, specifically Vol. 78, No. 4, pp. 354-370.  The purpose of this article to inform readers of the specific conditions on Earth during the periods when dinosaurs roamed the planet.
