The author used direct quotes from research papers, speeches, and other publications by experts in multiple fields from public health policy to medicine to government relations. These were discussed and examined against others to produce a discussion rather than just an article full of information.
The film is primarily the narratives of many first responders, so they play a large roll in the meassage being protrayed. They are seen as heros but also paid the price of their decisions through health issues.
I followed up by looking at rape rates across the world, how rape is regarded in different countries, and when humanitarian aid started.
The article was written in a very "flowery" style typical of fictional and/or emotionally appealing narratives. That being said, the majority of the information used was requoted or cited from articles and books recounting the major events. The portion on 9/11/2001 is largely based on reports from the incident, first hand accounts, and the author's personal opinion.
No bibliography was given, but the citations that are used in the article are likely from medical records or government records of some sort.
There clearly need to be some policy changes in the healthcare system. I think Obamacare is not the answer and is way too much policy and not enough sense, but we need something. People need affordable coverage for the issues that make sense for their gender and age bracket, they need to be given more help when they are trying to work, and there needs to be more incentive to become a doctor so that there are more PCPs out there nipping a lot of these issues in the bud. So the ER is for emergencies and is a less stressful, long-wait, ridiculous situation.
The author relied on a combination of resarch and personal experience to support his arguments. First hand experience during the time the policy was in effect also contributed to his knowledge on the subject.
It is difficult to determine where this document comes from. It deals with medicaid, so it is related to the government and healthcare.
"Moreover, in any mumber of disasters over the past two centuries, the 'disaster investigation,' far from proving itself the dispassionate, scientific verdict on causality and blame, actually emerges as a hard-fought contest to define the moment in politics and society, in technology and culture."
"And, no investigation he could provide would change the fact that most Americans viewed the burning of the Capitol in 1814 as a diplomatic and military, not an engineering, disaster."
"Certainly the move to NIST places a great premium on the power of "investigation" as not only a technical, but also a moral tool, a sacred act, assigning a higher meaning to the tests and calculations that must ultimately assign causes and fix blame--but this is nothing new in American history. While the investigator's tools may have sharpened since Latrobe's study of the Capitol, the Hague Street inquest, or the Iroquois Fire, disaster investigation still pits expert against expert, the demand for patient study against the will to rebuild and forget."
Emergency Response isn't directly addressed in the article. However there is one mention of emergency responders and the debriefing typically held after a traumatic event/call. But, the article also says that this method is not actually effective in preventing psychopathology, and can actually hinder the healing process by promoting exposure to traumatic memories.
