Science Living with Microbes

PART 1: TWO PAGES SHOULD ANSWER THESE 12 QUESTIONS

1. How is the annual flu vaccine prepared? Why do some people still get flu after receiving the flu shot?
2. What are different forms of vaccines made of?
3. How does innate immunity differ from adaptive immunities?
4. Provide an example for active immunity and passive immunity.  How do they differ?
5. What are the possible targets of antiviral drugs?
6. How does DRACO work?
7. What bodily fluids can transmit HIV?
8. How can HIV get transmitted from mother to child?
9. What are the structural components of an HIV virus? What types of cells does HIV attack?
10. The clinical stages of HIV infection are _____. If an infected person doesn’t seek treatment, the first stage lasts ____, the second stage lasts ____, the third stage lasts ____, and the last stage lasts _____.
11. Why an HIV infected person may be tested HIV negative?
12. What are the drawbacks of HAART therapy?

PART 2: ONE PAGE SHOULD ANSWER THESE 3 QUESTIONS

1. Under the protection of HIPPA law, doctors have no right to test patient’s blood for his HIV status without getting patient’s consent, even in the case when there is a needle stick injury during the blood draw of an intoxicated drug addict who doctors highly suspect to be HIV-positive.  Needle stick injuries are not uncommon considering the long working hours of doctors.  It’s common that medical residents work 36 hours straight with no rest in between.  Is this policy fair to the physicians and the patients? Why do you think so?  If you are the unfortunate doctor who had a needle stick injury at work, what can you do to prevent you from contracting HIV? Are there medicines available?  Are they costly?  Where do these medicines target the virus? Please cite at least one source to support your view.

2. Congregate living spaces have become COVID-19 hotspots due to ease of transmission and a lack of options for social distancing or quarantining. In this discussion, you will focus on one such living space of your choice (e.g., day care center, jails, homeless shelters, poultry factories, temporary farm workers, college students living in dorms, …)
-Describe your chosen living space and population.
-What are the impacts on the surrounding communities?
-How are black Americans and other people of color affected in comparison?
-What are some factors that contribute to differential COVID outcomes (infection & survival rates) among different racial groups?
-What should the government do to improve the health outcomes and control the spread of COVID-19?
-Cite at least one reliable resource in MLA format.

3. Easily said than done.  Although we understand the measures that can be taken to stop the spread of deadly viral diseases such as Ebola, health workers often face multiple difficulties when implementing them.  Listen to this NPR podcast (http://archive.kuow.org/post/ebola-ping-pongs-liberia-cases-disappear-jungle), name at least 3 types of difficulties and discuss how these obstacles can be overcome.

Global Climate Change

For the next discussion, research what are community groups doing to counteract this global climate change. Look for examples of Indigenous perspectives on the environment, sustainable lifestyle changes, earthen/green building, local community farming and markets, reforestation, planting trees, appropriate technology,  and permaculture to see what people are doing to reduce waste and emissions to sustain life on Earth.  Write 200 words about a practice that you find interesting or that you may even try to adapt at some point, summarize it, explain how it can potentially counteract global climate change. Relate specific examples of the book.

Post a link of where you got the information. A link to the website for non profit organization or the like acceptable.

Here are some links to get you started, but feel free to find others by googling any of the list of activities above.

end up having a citation. I will check citations.
4. DO NOT EVER quote from a scientific article, even if you attribute it. You must write
everything in your own words. Anything else is plagiarism.

The outline format:  Your outline must be formatted as described.  Please note that this format will be assessed in your grade:

Use an alphanumeric sequence
Sections should be indented and aligned
Follow the suggested order of the required elements
Use brief and bulleted but detailed and descriptive phrases.
The required elements: Your outline should contain the following elements in this order:

I.            The Introduction: This section previews your topic and the details you will cover in the body of your presentation. It should be very brief, but include:

    A.  The food, cuisine, invention or idea that you are going to discuss.

    B.  Why you chose this topic.

    C.  A preview of the regions where your topic has developed and then diffused to.

   

II.          The Body (Content Sections): In the body, you must address how the four geographic concepts mentioned in the presentation instructions (regions, cultural landscapes, diffusion, and distance decay) relate to your topic.

    A.  Regions: Discuss the origin region or regions of your topic, with specific attention to the geographic qualities of the region that influenced the development of your topic.

    B.  Cultural Landscape: Discuss how the landscape in the region(s) described above have been shaped by the culture that gave rise to your topic, and how your topic might be reflected in that landscape.

    C.  Diffusion: Discuss how your topic has diffused from its origin. Where has it diffused to? What factors led to its diffusion there? What kind of diffusion has it experienced?

    D.  Distance Decay: Discuss how your topic has changed as it has diffused away from the region(s) of its origin. Explain these changes with reference to the geographic qualities of the regions it has diffused to.

 

III.      The Conclusion Section: this section should contain four to six points that sum up the main points from the body of the outline.

Start your conclusion with one sentence summarizing some basic information about your topic.
Continue with a brief summary (1-2 sentences) about the important characteristics of its origin region(s).
Include a brief note about relevant cultural landscapes.
Include a brief summary (1-2 sentences) about the diffusion of your topic and the distance decay it experienced.
Wrap up the conclusion section with a closing note that provides brief information about why this topic was of interest to you, and a fact about your topic you found interesting.
IV.      Reference section: This is not just the reference page; rather, referencing should occur throughout the outline as it will in your presentation.  Therefore, your outline should include both a separate reference page containing a minimum of five sources listed in proper APA reference list format AND internal citations throughout the outline where appropriate.  Please be sure to see the resources below for assistance regarding in-text citations and reference list formatting, and/or ask me if you have any additional questions.

Please make note of the following tips and tricks:

I understand that this is a rough draft and, as your research and writing continue over the next few weeks, details may be added or changed.  Although you do not have to resubmit it to me, I recommend that you update this outline to help you best complete the Final Presentation.
Write your outline so that it has detailed bullets that you can easily then flesh out into sentences for the narration of your Final Presentation.
After your outline is complete, I recommend that you next draft your introductory and conclusion sections for your presentation.  This will ensure that all the main points of the outline are incorporated in these two framing sections of your final presentation.
Please note that less than 10% of your outline or presentation should be direct quotes.
All internal citation references should be listed on the reference page, and vice versa.

Earth’s Atmosphere

Formulate an organized, clearly worded, and succinct initial post that substantively covers all discussion points stated for your chosen topic. Because your initial post will be scored on the degree to which you meet these standards, there is no set minimum word requirement. However, there is a set maximum word requirement confine your initial post to 500 words. Remember that we are all reading each others posts, and one that is succinctly written is more likely to be read and responded to, thus furthering our discussion on that topic.
Include at least one graphic, video, or image that visually adds to some aspect of your post – as they say, pictures are worth 1000 words!
