Week 2 Feedback

• Thank you for submitting your assignment on time. Here is the feedback on your assignment.
• You wrote something in the summary field for 53 out of 54 saves (98%) since Week 1, which is excellent! Keep up the good work!
• The purpose that you wrote was more of a "learning" purpose instead of a "scientific" purpose.
  • You wrote: The purpose of this assignment is to gain a fundamental comprehension of the S.I.R. (susceptible, infected, recovered) model and its relation to the spread of diseases such as the current COVID-19 pandemic. Additionally, this assignment will illustrate the different types of models and their role in modern science.
  • I would revise it to be: The purpose of this assignment is to explore the S.I.R. (susceptible, infected, recovered) model of infectious disease transmission by altering the model parameters and interpreting the results. The results will be related to the current COVID-19 pandemic.
• With regard to your questions from the video:
  • How does the model account for people who have have been asymptomatic and recovered from the disease without their knowledge?
    • The one discussed in the video didn't, but the Giordano et al. (2020) showed a model that accounted for asymptomatic cases.
  • How much of a difference does the incidence rate of a disease change the graph of an S.I.R. model?
    • Did you explore this when you manipulated the model yourself?
• Your interpretations of the model graphs after you manipulated the parameters were good.
• Your explanation of the Giordano et al. (2020) article was good.
• Beyond making fun of people who make models, the XKCD comic is referring to how models have assumptions that can be limiting (in this case about the amount of mixing college students would do).
• Your conclusion needs to also be a little more specific. Restate in more detail some of the main findings that you made from manipulating the model parameters.
• Make sure to acknowledge your partner. If you did not work together, make a statement to that effect.
• To answer your questions that you posted in the class journal:
  • Why do some patients develop neurological symptoms (is it possible the virus can be carried through the blood)?
    • It's possible that the virus is infecting neurons because the ACE2 receptor is expressed on the surface of some neurons.
  • How long will it take to administer a vaccine to the entire American population?
    • The logistics of this definitely need to be worked out--everything from national supply chains to local clinics. It will not be instantaneous!
  • How does an S.I.R. model take into account people who are infected and asymptomatic?
    • Giordano et al. (2020) added more groups (boxes) to the model--more complex models have even more boxes.

Week 1 Feedback

I will be posting the feedback on your weekly assignments on your talk page. You will be able to earn back the points you lost on the Week 1 assignment by making the changes listed below by the Week 3 deadline on 12:01 am, Thursday, September 24. Here is the feedback for Week 1.

• Thank you for submitting your assignment on time.
• You completed all of the tasks except for the following:
  • You wrote something in the summary field 63 out of 71 saves (89%). That is very good! Remember we are aiming for 100%.
  • You need to have three levels of headers, and you only had two. You had the "==" and "===", but you need to go down one more level to "====".
  • For your list of assignments and class journals on your template, go back and add labels to the links. For example, instead of [[BIOL368/F20:Week 1]], use [[BIOL368/F20:Week 1 | Week 1 Assignment]].
  • Note that there is no Week 13 assignment, so you can remove that link from your list of individual and class journal links.
  • The word "Individual" is spelled incorrectly.
  • In your Acknowledgments section, make a link to your partner's user page.
• Your example of the Digital Smile Design reminds me of the different model representations we talked about. It would be a visual and experiential model that needed underlying symbolic and numerical models inside the software.
