Delivery & Style of 3 Sources

Harrison Vaughan delivers his blog through a digital setting, on the internet. He most likely did this because it's most accessible to people, most everyone has a computer. He makes it relatable to his audience because he starts with "I’m sure you’ve heard of the saying, 'Look Ma, No Hands!' and may have said it yourself when you first took your hands off of the bicycle", which made me more interested right from the beginning.
The style he uses is obviously professional, because he knows his stuff. I can tell because he discusses his past experience so the audience knows he is credible. He gives a lot of examples of what he's trying to say so that his audience understands completely what he's trying to get across. He also makes it seem like what he's saying is important for the patients. He reiterates the importance of decreasing bias when physical therapists assess the patient's healing. He also puts a lot of explanation into the different processes. It made me think that I could trust what this guy was saying.

Newspaper article: http://www.nytimes.com/2012/05/29/world/asia/patching-troops-together-one-ache-at-a-time.html?pagewanted=1&ref=physicaltherapy
Graham Bowley delivers this article in a very sincere way. I read it as a digital source on the internet, but it also was in the actual New York Times newspaper. So, it is very accessible to a variety of audiences. The reason I think it's sincere is because he delivers it with a picture of a woman in the army, helping an army guy with a bad leg. And he starts the article with giving her a lot of credit. I think he wants to make it known right away that this is a touching story. Probably to catch more attention I'd say.
The style he uses is very serious, because it's a serious situation. He tries to make the audience feel some pity for the soldiers. He describes what the soldiers have to go through in great detail, and gives facts like that there's only one physical therapist for a combat of 100 soldiers. He did a good job of using this style to affect the audience. He almost made it feel real to me, and allowed me to understand what it's like for soldiers and physical therapists in war. It was very affective.

Scholarly Article: http://search.proquest.com.proxy2.cl.msu.edu.proxy1.cl.msu.edu/docview/223126513/1392409039DCA4F751/11?accountid=12598
The article, "Physical therapy to improve functioning of older people in residential care facilities" was delivered very basic, and not personal or made relateable at all. It's on the internet so it's accessible. It seemed very straightforward. I take this as a professional, quick research when I see this delivery. 
The author, Nancy Harada, has a very blunt, straightforward style. Just a proffessional tone. She gives her research, process, and results, that's all. It was just very quick and impersonal.
