26 pt (2 pt for each question)
For this assignment, you’ll read a paper published in a medical journal, Lancet. One of the purposes of the assignment is to show that you don’t have to understand everything in a journal article to get something out of reading it. I don’t expect you to understand everything.
This article was the one that started the suspicion in the U.S. and Great Britain that vaccines cause autism. Because of some parents not vaccinating their kids, the incidence of measles has increased in the U.S. Measles causes a rash and fever in most cases. Other possible symptoms are diarrhea, ear infections, pneumonia, seizures, blindness, and inflammation of the brain. Dr. Wakefield, the main author of the article, moved to the U.S. and as of May 2020 was part of protests against social distancing and using vaccines to fight COVID.
The article was published in a peer-reviewed journal, which normally is a process that makes sure that only high-quality articles are published. The editors of the journal admitted that they made a mistake and published a really bad article. Science journalists also admitted that they made mistakes in publicizing the findings without talking with other researchers first.
Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children. A J Wakefield et al. Lancet 1998; 351: 637–41.
How the case against the MMR vaccine was fixed. BMJ. B Deer. BMJ Jan 2011. 342: 77-82.
Note: Wakefield et al.’s paper was retracted by the journal, Lancet. Even though the paper was peer-reviewed, reviewers and the editors didn’t catch the mistakes before it was published.
Questions on Wakefield, et al. (1998).
What did Wakefield et al. investigate?
What was the question that data shown in figure 1 answers? (The amount of methylmalonic acid excreted in urine is a measure of Vitamin B-12 deficiency.)
Notice that the two groups of children (patients vs. controls) weren’t found in the same way. a) How might the two groups of children be different from each other? b)What is the problem with interpreting results if the two groups are different?
Did the authors report a potential conflict of interest, such as working at or being funded by a company that manufactures a product?
Did the authors report receiving funding from grants? (Check the fine print in the article, often on the bottom of the first page of the article or just before the reference section.) If it’s not clear where the funding came from, that’s a problem.
Questions on “How the case against the MMR vaccine was fixed”:
What was the undisclosed goal of Wakefield’s study, according to Deer?
How accurate were Wakefield’s statements that all of the children were “previously normal” before MMR vaccination?
How were the children for the study actually selected (different from methods reported)?
What were the long-term consequences of publishing Wakefield et al’s paper?
Did Wakefield et al.’s data and interpretations merit the public concern about the MMR vaccine? Explain.
Parents are concerned because the rates of autism and other developmental disorders reported in the U.S. appear to be increasing. What is another possible explanation for the increase in rates of autism?
What could reporters have done to make sure that they covered the results of this research correctly?[supanova_question]

Assignment # 3—Funding Stem Cell Research
Stem-cell-based research has shown the potential to generate effective therapies to treat diseases such as Alzheimer’s, Parkinson’s, diabetes, and some cancers. However, stem cell research is quite controversial, as it involves many ethical issues, including when human life begins.
In 2001 the federal government announced that it would support only a limited funding of stem cell research of existing cell lines which are held by a relatively small number of laboratories. With the funding decision, stem cell research slowed dramatically in the United States as researchers experienced great difficulty obtaining the cells they need.
The federal decision does not prevent individual states from passing laws to permit and fund human embryonic stem cell research. For example, in 2004 the state of California passed a measure authorizing $3 billion supporting embryonic stem cell research.
What about your state—should your state support stem cell research?
Below are sites that review the potential of stem cell therapies and the controversy surrounding government support of stem cell research:
Compose a letter (~500 words) to your state representative, state senator, or governor, expressing your position on your state’s (potential) funding of embryonic stem cell research. You do not have to mail the letter. You must clearly communicate your understanding of:
• The biologic role of stem cells, including their unique characteristics.
• The difference between adult and embryonic stem cells.
• The potential benefits of embryonic stem cell research.
• The controversy surrounding the issue of governmental funding of embryonic stem cell research.
Guidelines for writing a letter to your state representative, senator, or governor can be found at:
This assignment is designed to help you understand the differences between qualitative
This assignment is designed to help you understand the differences between qualitative and quantitative research designs, as well as select the appropriate method for the research question you have been working on throughout the course.
Create an APA formatted cover sheet.
Step 1: Use the recommended research question from Week 1 and select the type of research approach (quantitative or qualitative) that is most appropriate for it.
Step 2: Summarize the major steps in that type of research.
Step 3: Determine the specific study design (i.e., quasi-experimental, phenomenological, etc.) you would employ and explain why that is the best selection. Note your proposed sample type.
Step 4: Explain your sample type and how you would collect data for your study.
Step 5: Explain the basic statistics you would use for a quantitative approach or the basic analytics you would use for a qualitative approach to analyze your data.
Format your assignment as one of the following:
· 10 to 15-slide presentation formatted per APA
· 10 to 15-minute oral presentation
· 800-word paper per APA
· Another format approved by your instructor
Cite at least one peer-reviewed resource in APA format.[supanova_question]
