FIRST PAPER( 2 PAGES) Post a brief description of the two studies you selected, with a particular focus on the study design and analysis methods they used. Describe at least one strength and one limitation of each study’s design and/or methodological approach for the research questions it addressed. Identify any measures that the authors used to minimize the limitation. Finally, share your insights about the value of the special study designs used in terms of advancing epidemiological knowledge SECOND PAPER ( 2 PAGES) Ethical Research Practices When many people think of research ethics, they think of the informed consent process. The informed consent process allows potential research participants to make a knowing, considered decision to participate voluntarily. In the 21st century, informed consent and other research ethics practices are facing new challenges, such as the handling of “big data,” genomics research, and the need to study rapidly and ethically the emerging infectious diseases in times of pandemic threats. With these thoughts in mind: Review the Learning Resources for this week. Choose one of the following ethical challenges to address: • The use of “big data” in research • Genomics research • The study of emerging infectious diseases Post a description of the ethical challenges facing epidemiological researchers in the 21st century for the topic you chose. Identify at least two strategies for addressing these ethical challenges. Finally, explain how you will address ethical integrity in research during your dissertation research process. Be sure to support your postings and responses with specific references to the Learning Resources and additional appropriate scholarly references.
