Effects of the physical environment on population health
Eight to ten slides on a subject that could fill a semester, so the work is selection. Choosing two or three environmental exposures and showing the pathway to health beats naming twelve.

Eight to ten slides on the physical environment
The scope problem is the real difficulty here. The physical environment's effects on population health could occupy a whole course, and eight to ten slides cannot survey it, so the presentation lives or dies on selection. Choose two or three exposures and treat each properly rather than listing every environmental determinant you can think of. Air quality, water and sanitation, housing conditions, the built environment and walkability, heat and extreme weather, and occupational exposure are all defensible choices, and the strongest presentations pick ones that interact — housing quality and asthma, for instance, or heat and the built environment — because interaction gives you something to say beyond description, and ten slides reward depth over coverage. Say explicitly on an early slide which you chose and why, so the narrowing reads as a decision rather than as an omission, which is a distinction assessors make consistently on presentation work.
For each exposure, show a pathway rather than an association. That means naming the exposure, the mechanism by which it affects the body, the health outcome, and the population most affected — because environmental burdens are never evenly distributed, and the distribution is usually the most interesting slide in the deck. Particulate matter irritating airways and worsening asthma control in children living near freight corridors is a pathway; air pollution is bad for health is not. Use the speaker notes as the brief instructs, keeping the slides visual and putting the commentary underneath, and remember the presentation needs a cover page and at least two references. A map or a chart showing unequal exposure will do more work than three bullet points, since the whole point of a presentation format is that some arguments are better seen than read, and unequal exposure is exactly that kind of argument.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Select a small number of environmental exposures and justify the narrowing.
- 02Trace an exposure through a mechanism to a health outcome in a named population.
- 03Present quantitative evidence visually rather than as bulleted text.

Course-wide instructions that accompany this question
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes. Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages. Discussion: Global health and quality control Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor. The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument. ADDITIONAL INSTRUCTIONS FOR THE CLASS Discussion Questions (DQ) Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses. Weekly Participation Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week. APA Format and Writing Quality Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. I highly recommend using the APA Publication Manual, 6th edition. Use of Direct Quotes I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source. LopesWrite Policy For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score. Late Policy The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading. Communication Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours. Discussion: Global health and quality control
Turn the brief into deliverables
- 01An 8-10 slide presentation with a cover page.
- 02Two or three exposures each treated as a pathway.
- 03Speaker notes providing commentary on each slide.
- 04At least two references in APA format.
Naming effects, then showing the pathway
Cover and scope
Title the presentation and state which exposures you selected and why.
Exposure one, as a pathway
Name the exposure, mechanism, outcome and affected population.
Exposure two, as a pathway
Repeat for a second exposure, ideally one that interacts with the first.
Distribution and inequity
Show visually who bears the exposure and why the burden is uneven.
What can be done
Identify interventions at the environmental rather than individual level.
Environmental health data for a named place
Recommended databases
- CDC environmental health resources
- EPA
- Environmental Health Perspectives
- WHO environment and health
- County Health Rankings
Search sequence
- 1.Choose your exposures before searching, so the reading is focused rather than exploratory.
- 2.Look for a chart or map you can reproduce with attribution, since a visual is worth several bullets.
- 3.Find data at a named geography rather than nationally, which makes the distribution slide concrete.
- 4.Check publication dates on exposure data, particularly for air quality, which changes year to year.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.
Nothing here is cleared for citation until you have read it.
