1. Voluntary consent of the participant is absolutely essential. The subject must be capable of giving consent without coercion, and full responsibility for obtaining consent rests with the principal investigator. 2. The experiment must be designed to bring forth results that will benefit society and that cannot be obtained in any other manner. 3. Human experimentation should be based on animal research results as well as knowledge of the natural course of events, disease, or problems. 4. All unnecessary mental or physical harm should be avoided. 5. When there is reason to believe that death or disabling injury may occur, no experiment should be conducted except, perhaps, when the experimenting physicians also serve as subjects. 6. The degree of risk should never exceed the humanitarian importance of the problem to be solved. 7. All precaution should be taken to protect subjects from even remote possibilities of injury or death. 8. Only qualified personnel should be allowed to conduct experiments. The principal investigator must be ready to terminate the experiment at any stage if it appears that injury or death will result.

Chapter 4: Considering Ethics in Research
Explain two basic principles for humane treatment of human subjects in research. Drawing on the course readings or a current news item, provide an example of a study in which ethical principles were not followed. How might study design have been improved in that case?

The two basic principles for human treatment of human subjects in research most significant to me are, making sure all precaution is taken to protect subjects from even remote possibilities of injury or death, and allowing the subject to withdraw from the experiment at any time if a point is reached that may bring about physical or mental harm. It is important that we do not use humans in research as crash dummies, as if they are simply replaceable after harm and injury. It is only right to take all precautions and allow the human subject to change their mind about participating in the research.

Ethical principles were not followed in the Tuskegee Syphilis Study found in our text. The human subjects were not fully aware of the study, and the purpose of the research was more so the subjects could die and they could perform an autopsy.

Week 1 DQ 2

What are the advantages of using a mixed method approach to research? What are the challenges? Provide an example of how you have used (or, in the future, could use) this approach in your professional role.

The strength of the research;
2) Use of multiple methods in a research helps to research a process or a problem from all sides; 3) Usage of different approaches helps to focus on a single process and confirms the data accuracy. A mixed research complements a result from one type of research with another one. This research does not miss any available data.

The aim of a mixed method design is to summarize positive aspects of two approaches and produce a highly accurate data.

When you use several methods in your research process, then you can use the strength of every type of information collection and minimize the weak points of every of both approaches. A mixed method approach of gathering and evaluation can increase the validity and accuracy of the information.

The advantages of using a mixed method approach to research are having several different outcomes in the process of your research. What this does is allows the researcher to use the strengths from the information collected and minimize the weaknesses from the information collected. Using a mixed method approach can ultimately increase the accuracy and validity of the information. The challenges of using a mixed method approach will be that the time of researching will be extended. Extending the time of research could definitely be a challenge if there is a time frame...
