Models And Theories In Action


Models and Theories in Action


This assignment gives you an opportunity to examine how a public health organization puts a public health theory or model into action through their efforts to improve public health.

In this assignment, you will:

  • Study how a public health organization is currently working to address a public health issue.
  • Apply the appropriate theory or model to deepen your understanding of how the organization works to improve public health for their constituents.
  • Connect what you have read in scholarly journals about a current public health issue to the real-world challenges faced by organizations working to make a positive difference in the field of public health.


  1. Select a public health issue and describe the impact of a current public health issue in your community. Be sure to cite your sources for the impact information you provide.
  2. Identify an organization that is currently working on this public health issue in your local community. Do some background investigation of their activities:
    • Visit the organizations Web site and Facebook page or other social media.
    • Search the library to find out if there are any published studies referencing the organization.
  3. Identify and apply a  theory or a model (at the community level) and determine how well it aligns with the interventions the organization is currently using.
  4. Use your theory or model to explain how the various activities of the organization will help improve public health for their constituents. In your explanation, provide examples that demonstrate how the theory or model does or does not support their activities.
  5. Using an appropriate theory or model, propose several recommendations for the organization to improve the outcomes for their constituents. Support your recommendations with the literature, Remember to use APA format and style to cite your sources.

Evidence-Based Practices In Public Health


Evidence-Based Practices in Public Health

Effective public health practice systematically identifies gaps in health and health care and tracks down evidence-based programs to close those gaps.

Arlene Fink, Evidence-Based Public Health Practice.


Create a 23 page paper discussing evidence-based public health practices related to a specific public health issue. 


Select one of the following public health issues and examine evidence-based public health practices:

  • Obesity.
  • Transportation to health center.
  • School violence.
  • Zika virus.

Complete the following:

  • Discuss the issue:
    • Describe the problems related to this public health issue.
    • Present properly cited evidence to support your description of the issue.
  • Discuss practices and interventions:
    • Which evidence-based practices or interventions does the literature suggest to address the issue?
    • How effective are the interventions?
  • Describe a public health organization or agency that is attempting to address this issue:
    • Which of their interventions have proven effective in reducing the impact of the health issue?
    • What are some controversies that may arise from actions that an agency has taken or may take?
  • Based on the evidence and what you can ascertain about practices currently used by this agency, is there anything that could be changed or improved upon? What would you recommend the agency focus on?

Additional Requirements

  • Page count: 23 pages plus cover and reference pages.
  • Font: Times New Roman, 12 points.
  • APA Formatting: Resources and citations are formatted according to APA style and formatting.
  • Number of references: Cite all references. Include at least three peer-reviewed resources.

Note: Before submitting this paper, you should refer to the Guiding Questions (linked in Resources) to ensure that you have addressed all of the assignment criteria.

1. The United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) was developed to promote the sound management of chemicals. This is an agreed upon management approach, but regulatory authorities in countries adopting the GHS will implement the system according to their own regulatory processes. After reflecting on the aspects of chemical management that the GHS system covers, describe how you believe the GHS system will affect you or others in your field as your perform your various job functions.

Your journal entry must be at least 200 words. No references or citations are necessary.

2. The Hazardous Materials Safety Administration published the Emergency Response Guidebook and has developed a free, mobile web app of the Emergency Response Guidebook (2016). Reflect on the information available in this guidebook or through the app and on the format in which it is presented. Which resource (hard copy or mobile app) would be a more effective tool for you in the workplace and why?

Your journal entry must be at least 200 words. No references or citations are necessary.

3. Look around you, and find five examples of matter that you encounter every day. For each example, detail the physical state and whether it is a pure substance or a mixture. List one physical and one chemical property of each of the substances selected.

Your journal entry must be at least 200 words in length. No references or citations are necessary.

4. While much of the chemistry you will be learning about in this class has not changed during the last 20 or more years (with the exception of some added elements), there is new chemical research and news happening all around you. What innovations in chemistry interest you the most? How has or will this innovation impact your life or community?

Your journal entry must be at least 200 words in length. No references or citations are necessary.

Pharmacokinetics And Pharmacodynamics

 Reflect on a case from your past clinical experiences and consider how a patients pharmacokinetic and pharmacodynamic processes may alter his or her response to a drug.

To Prepare

Review the Resources for this module and consider the principles of pharmacokinetics and pharmacodynamics.

Reflect on your experiences, observations, and/or clinical practices from the last 5 years and think about how pharmacokinetic and pharmacodynamic factors altered his or her anticipated response to a drug.

Consider factors that might have influenced the patients pharmacokinetic and pharmacodynamic processes, such as genetics (including pharmacogenetics), gender, ethnicity, age, behavior, and/or possible pathophysiological changes due to disease.

Think about a personalized plan of care based on these influencing factors and patient history in your case study.

Periodic Table Assignment


  • Print out and cut out the attached element cards so that they can be arranged and organized.
  • Read through each of the element cards you are given. Look for similarities between the elements and create groups that have the most similarities.
  • Within each group, try and arrange the elements in a logical way.
  • Show your arrangement of all 12 elements by drawing a table and writing the letter of each element in the cells of the table. (create a column for each of the groups you sorted them into)


1. What similar properties did you use to form each group?

2. Within each group, how did you decide to organize the elements?

3. Based on what you have seen about periodic properties, predict the properties for the element that would be in the same group as element T but with higher mass (i.e. it would sit below element T on the periodic table).
