Analysis of Assigned Article

  1. We will now create a shared bibliography for the entire class. Go through the search results that you have found and add articles to the class shared bibliography page.
    • Only add articles that are unique (everyone will be adding to the page and we do not want redundant articles)
    • Put review articles and primary research articles in their respective sections. If the article does not fit either of those two categories, place it in the other articles section.
    • Add the articles in APA format (re-find them in Google Scholar to easily obtain APA format, if necessary). Add your wiki signature to the end of the citation.
    • Ideally, each student will contribute 2-3 unique articles.
  2. Now that we have our shared bibliography, each student will be assigned one article. Record the citation for your article in APA format:
    • Roop, J. I., Cassidy, N. A., Dingens, A. S., Bloom, J. D., & Overbaugh, J. (2020). Identification of HIV-1 Envelope Mutations that Enhance Entry Using Macaque CD4 and CCR5. Viruses, 12(2), 241.
    • In Web of Science, search for the specific article that you have been assigned.
      • How many cited references does that article have?
        • n/a (not available on Web of Science)
      • How many articles have cited the article you have been assigned?
        • n/a (not available on Web of Science), likely 0 since it was published this year
  3. What are the relative merits of searching with Google Scholar, PubMed, and Web of Science? Name two advantages and disadvantages for each.
    • Google Scholar
      • advantages - easy to use, able to generate citations, produces a wide range of results
      • disadvantages - not all articles are available for use, unable to see if article have been peer reviewed, unable to see if articles are primary literature or reviews
    • PubMed
      • advantages - provides a list of similar articles, more filters allowing for more specific search results
      • disadvantages - does not provide many articles
    • Web of Science
      • advantages - best of the three for focusing searches and finding information about articles
      • disadvantages - expensive
  4. What impact does choice of keywords have on your results?
    • Keyword choice has a significant impact on search results. Broader, more generic keywords will result in a larger list of results, and vice versa for more specific keywords. Also, the order and arrangement of keywords in the search bar can make a difference in results produced.
  5. Now we will begin to evaluate your assigned article in three areas availability, the journal, and the article metadata. Again, provide a citation for the article in APA format, this time including the DOI. For the following questions, for information that is not available, answer n/a).
    • Roop, J. I., Cassidy, N. A., Dingens, A. S., Bloom, J. D., & Overbaugh, J. (2020). Identification of HIV-1 Envelope Mutations that Enhance Entry Using Macaque CD4 and CCR5. Viruses, 12(2), 241. https://doi.org/10.3390/v12020241
    1. Provide a link to the abstract of the article on PubMed
    2. Provide a link to the full text of the article in PubMed Central

    4. Provide a link to the full PDF version of the article from the publisher website.

      • The authors
    6. How is the article available to you:
      • The article is open access.
  6. Evaluating the source--the journal
    1. Who is the publisher of the journal?
      • MDPI
    2. Is the publisher for-profit or non-profit?

      • no
    4. Does the publisher belong to the Open Access Publishers Association?
      • yes
    5. What country is the journal published in?
      • Switzerland
    6. How long has the journal been in operation? (e.g., browse the archive for the earliest article published)
      • since 2009
    7. Are articles in this journal peer-reviewed?
      • yes
    8. Provide a link to the scientific advisory board/editorial board of the journal.
    9. What is the journal impact factor (look to see if it is provided on the journal home page; often you can also find it through a Google search)?
      • 3.811
  7. Evaluating the source--the article
    1. Is the article a review or primary research article?
      • primary research article
    2. On what date was the article submitted?
      • 27 December 2019
    3. On what date was the article accepted?
      • 19 February 2020
    4. Did the article undergo any revisions before acceptance?
      • not stated that there were any revisions
    5. When was the article published?
      • 21 February 2020
    6. What is the approximate elapsed time between submission and publication?
      • 2 days
    7. What are the institutions with which the authors are affiliated?
      • Fred Hutchinson Cancer Research Center
        • Divisions of Human Biology
        • Basic Sciences
    8. Have the authors published other articles on this subject? (How will you find this out?)
      • Searched by author on PubMed to find out
      • Roop J. I.: no
      • Overbaugh J.: yes
    9. Is there a conflict of interest for any of the authors?
      • there is no conflict of interest, according to the authors
    10. Read the abstract. Write 1-2 sentences about the relevance of this article to understanding the structure-function relationship of mutations in the HIV-1 gp120 protein.
      • HIV-1 strains do not replicate well in Rhesus macaque cells due to a non-synonymous mutation in macaque CD4 that restricts HIV-1 env-mediated entry. Several induced mutations from this study have been found in gp120 that enhance binding of HIV-1 to macaque CD4.
    11. Make a recommendation--based on the information you have gathered, should we do a journal club on this article? Why or why not?
      • I think that it would be interesting to do a journal club on this article. Based on the abstract, it could provide useful information about the structure-function relationship of the mutations in the gp120 sequence of HIV-1. The journal is open access since the publisher has been committed to that movement in the research community, so the class will be able to easily read the article. There were no conflicts of interest, and the chief overseeing researcher (Julie Overbaugh) has published other articles on the subject. However, the article is new so there is no information about its relevance to HIV research. The journal and publisher are also relatively new, the former being created just over 10 years ago and the latter being established in 1996. The impact factor of the journal (3.811) is decent, but nothing notable. Because everything from the publisher to the article is fairly new, it is difficult to really get an idea of the quality of the article, but I think it would be interesting to give it a shot.
  8. Copy your 1-2 sentence statement about the relevance and the recommendation (plus justification) and paste into the class shared bibliography as a bullet point underneath your assigned paper.

Scientific Conclusion

The purpose of this assignment was to look for research articles that could be useful for upcoming projects on the structure-function relationship of gp120 using different search engines. This exercise highlighted how many factors can play into information literacy. While I had an idea that the way were used keywords made a difference in search results, it wasn't really apparent to me of how much of a difference they can make until this assignment. This assignment also showed me how much of an influence different search engines had on search results and access to articles. This was something I had completely overlooked and it was interesting to see how different results were between the search engines despite me using the same keywords. I also did not know about the open access issue in the research community and thought that was interesting and cool to learn about.
