Landfill, Contaminated Soil, and Contaminated Water

Scenario:
Once causation has been determined, epidemiological principles can be used to lessen risk by considering the policies that lead to unnecessary exposures.

Centervale’s landfill facility has accepted, with the town’s approval, contaminated soil from the Middle Earth Energy Corporation. The landfill is located above ground and the operators plan on selling the soil to small farms in the county.
The soil is known to be contaminated with polychlorinated biphenyls (PCBs) and lead that exceed the limits set by the Environmental Protection Agency (EPA). In the past, the EPA has discovered several leaks in the landfill’s liner.
The landfill is located above the town’s main aquifer, which supplies well water to 10,000 residents who live in either Simon Township (ST) or Diamond Township (DT). In Taylor Township (TT), 750 residents use both well water and Metropolis water for small farms. The other residents only use well water.

Directions
Research the public health implications of water contamination. Use information from the EPA, Centers for Disease Control and Prevention (CDC), and National Institutes of Health (NIH). Respond to the following:

  1. Identify and define all exposure and health risks from PCBs and lead.
  2. Develop a dose-response assessment curve for adults and children for PCBs and lead.
  3. 3. Calculate the proportion of people in Centervale who are exposed to well water (i.e., water from the aquifer) and Metropolis water. Show your work.

You should utilize at least 2 scholarly sources beyond the course readings in your research. Your paper should be written in a clear, concise, and organized manner; demonstrate ethical scholarship in accurate representation and attribution of sources; and display accurate spelling, grammar, and punctuation.
Write a 4–page report in Word format. Apply APA standards to citation of sources.

Project: Scholar-Practitioner Project: Public Health Leadership Theory

For your final written assignment, you refine and develop your Public Health Leadership Theory based on leadership theories and a systems approach learned in this course. For this Assignment, your theory should reflect Instructor feedback, researched studies, introspection, innovation, and literature analysis.
The Assignment (9–12 pages):
Section 1 — Abstract and Introduction (1–2 pages)
Section 2 — Revised Literature Review and Problem Statement (5–7 pages):
Literature Review to include:
A synthesis of the literature of 15–20 peer reviewed, scholarly resources
A description of theoretical gaps in the research
Problem Statement to include:
An explanation of the specific problem that addresses identified gaps within the literature
An explanation of how your problem statement incorporates implications for positive social change.
Section 3 — Personal Public Health Leadership Theory (2–3 pages):
An articulation of your personal Public Health Leadership Theory
Section 4 — Revised Visual Representation of Your Public Health Leadership Theory (3–4 pages):
Your visual representation should include:
Your personal Public Health Leadership Theory to address the gaps identified in the literature
A visual representation of the theory (e.g. table, graph, matrix)
A explanation on how the theory addresses the literature gap identified in Week 5
A description of how your theory incorporates aspects of systems thinking
Section 5 — Empirical Evaluation Plan for a Public Health Leadership Theory (3–4 pages):
You will assess if the newly developed leadership theory addresses the problem you have been working on. What methodological steps will you use? How will you collect data? Suggestion – start with how theories in our text are evaluated. It does not have to be detailed, but it must include the methods, measures and analytic techniques.
If the assignments are done correctly, there should be an alignment from the topic of choice to the evaluation:
The topic is researched in the literature
The literature review points out a theoretical gap that needs to be addressed by leadership
The gap is turned into a problem statement
A leadership theory to address the problem proposed
The theory is depicted in a visual; and finally
An evaluation plan describes how the newly developed theory resolves the problem identified in the literature
To further help, examples (Two final projects – permission given to post) are located in the Doc Sharing area for this week
Section 6 — Conclusion (1–2 pages)
Section 7 — References
An APA-formatted reference list of 15–20 peer-reviewed, scholarly journals

Hypothesis Test
Remember to use subscripts where appropriate.
 
A study of dental pain (http://www.endoexperience.com/documents/PIIS0099239911010375.pdf) found that patients given ibuprofen on the 1st day after surgery had a mean pain rating of 62.7. Assume that this is the population mean pain rating of all dental patients given ibuprofen on the 1st day after surgery.
 
Claim: 2-pain medications are better than one. Giving both ibuprofen and acetaminophen would cause patients to have a mean pain rating on the first day after surgery <62.7.
 
Perform all 4 steps of the hypothesis test of the claim, given that the same dental pain study with the link above collected a sample of 35 dental patients and gave them both ibuprofen and acetaminophen through the first day after surgery.
The mean pain rating of the 35 patients=54.6
Standard deviation= 43.4.
Use the 0.05 significance level.
Clearly show Step 1 to Step 4
 

  1. Is ibuprofen alone significantly different (in the statistical sense) in relieving pain than ibuprofen and acetaminophen together?
  2. Which medication(s) would you rather take for dental pain given these results?

 

  1. Explain your choice of medication(s) in number 2 above.
