Data analysis 6. Interpretation 7. Communicate findings 8. Initial Idea Wednesday, January 27 th Significance (page 56) Set at 5% or 0.05 (p = 0.05) is the most optimal The lower the value, (p < 0.05), the better the chance that the outcomes of the experiment did not happen due to chance Chapter 3 – Ethics (video)  History has taught us about ethics  Ethics continue to be added/reformed to this day  People suffering from mental health, substance abuse are viewed as invaluable to society  Lobotomies were highly regarded in the past, obviously now they aren’t  Physicians were really focused on benefinance, but now doctors are really focused on each patient individually  Nazi Germany tested on prisoners unethically, which led to the Nuremburg Code. Nazi’s used people of less power/invaluable to them as their subjects  U.S. vaccine experiments where people were subjected to a disease (usually people in institutions and orphans) and then they were used to test new vaccines or they were given no vaccine if they were part of the control group o These experiments were justified because they were “contributing to the war effort” (This occurred during WWII) o In a study, students at a school for mentally disabled kids were injected with hepatitis and consent was basically forced – the kids couldn’t go to the school without participating in the study  Tuskegee Syphilis Study: o Conducted in rural Alabama by the Public Health Administration on African Americans to see what would happen if syphilis was left untreated o Men weren’t told that they had syphilis o Even after penicillin was developed in 1940, they continued to not tell the men about their diseases and did not treat them o African American community had a strong mistrust towards the public health administration during that time  1974 – the National Research Act was passed, which established the National Commission, who published the Belmont Report  Some researchers believe that the IRB is exceeding its power, which is beneficial for participants because the information they are provided has to be complete and clear  Protection needs regulation and committees  Trust between experimenter + participant needs to be there, no one wants to be a guinea pig  Rule of thumb for experimenters questioning ethics: would you allow your grandmother to participate in this study? th Friday January 29  IRB approval is NEEDED for research. Research: is a systematic investigation designed to contribute to enhancing and expanding general knowledge Non-research: researching literature, quality assurance testing, interviewing individuals where questions focus on objects NOT people, even questions about policies and regulations
