s a medical research technician, you have been assigned the task of modeling the growth of five different strains of the E. coli bacteria. These bacteria are grown in Petri dishes and exposed to the same environmental conditions (food source, pressure, temperature, light, etc.). Each hour, you count and record the number of bacterial cultures in each of the sample Petri dishes. The results for the first 7 hours of observations are recorded in the chart below:

 

Directions: Assuming that the growth pattern for each bacterial sample follows a geometric sequence, determine the following:

 

1. Determine the rate at which the culture grows in a hour. This rate will be the factor r by which the number of bacterial cultures has increased since the last recorded observation.

 

2. Write a formula that represents the growth of this bacteria based upon your observations. Your formula will be based upon the basic format for a geometric sequence:

 

 

3. Using the formula you’ve developed, determine the number of cultures you would expect to see in the Petri dish on the 8th, 10th, and 12th hour of your observations.

 

4. Compute the total number of bacterial cultures observed after 24 hours of growth assuming that the growth follows a geometric series.

 

5. Repeat steps 1–4 for all five bacterial samples.

 

In a Microsoft Word document, prepare a report that includes answers to the following:

 

1. 1. Report the results of the calculations you performed above.

 

1. 1. Which strain of E. coli exhibited the highest growth rate?

 

1. 1. Which strain of E. coli exhibited the lowest growth rate?

 

1. 1. Assuming that all five of the E. coli strains present a high toxicity danger to humans, which do you suppose would be the most manageable based upon growth? Why?

 

1. 1. Consider how you’ve modeled the growth of the E. coli strains using the concept of geometric sequence. Is this a realistic approach to modeling bacterial growth?

 

1. 1. What other factors do you think should be considered when modeling the growth of bacteria such as E. coli?

 

1. Conduct an Internet search for research on E. coli. Look for information related to growth rate, environmental conditions conducive to growth, methods of controlling growth, etc.

Health Information Confidentiality

 

The HIPAA is designed to protect the privacy of individuals’ health information. The Health Information and Technology for Economic and Clinical Health (HITECH) Act was passed as part of the American Recovery and Reinvestment Act (ARRA) of 2009, in part, to strengthen the HIPAA rule and notification requirements in the case of a breach.

But information collected by various health departments, like the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) is typically “confidential,” not “anonymous.”

“Confidential” denotes identifiable information linking you to the subject matter, but which will not be disclosed.

“Anonymous” refers to the existing subject matter that cannot be linked back to you.

Using the South University Online Library or the Internet, research about HIPAA and the HITECH Act to find out how they protect health information of individuals. Based on your research and understanding, provide answers to the following questions:

• What are some safeguards that you think could be put into place to reduce fear among individuals and groups who oppose identifiable health data collection?
• Do the benefits of confidential health data collection outweigh the risks? Why or why not?
• What, according to you, is the purpose of HITECH?
• What are the new notification requirements? Do you feel these are sufficient? Why or why not?
• What possible HIPAA violations could occur with portable PHI?
• What strategies should be put into place to make sure these violations do not occur

The HGP

 

Bioinformatics is a subfield of medical informatics that deals with molecular biology. It is primarily used in genetics and genomics, specifically in DNA sequencing. Rapid developments in this area of science have led to an enormous amount of information that needs to be entered, organized, and mined for further analysis and sequencing. While the project was technically completed in 2003, analysis of the data is still going on and will continue well into the future.

Using the South University Online Library or the Internet, create a 10- to 12-page report in a Microsoft Word document that answers the following questions:

• What, in your own words, is human genome project (HGP)? What are its goals? Why is HGP an important part of the evolution of bioinformatics?
• Which legal and ethical issue will you select from the HGP website for further discussion? Why do you believe that the issue you have selected is of high importance for discussion? What are the criticisms or concerns surrounding this particular issue?
• What response or solution does the HGP provide for the concerns and criticisms of the above issue? Do they identify any of their own concerns?
• What role do you think medical information professionals should play in addressing such ethical, legal, or social issues?
• What is personalized medicine? What are the different applications?
• What are the legal and ethical considerations for personalized medicine, including HIPAA? What types of standards and interchangeability issues must be addressed before adopting?
• What are some of the information issues that will need to be addressed in the next ten years?

To prepare for this Application, first focus on the following instructions:

• Review Chapter 10 in the course text, Research Design, the “Trustworthiness” and “Threats to Internal Validity” handouts, and the “Mixed Methods: Examples” media segment.
• Review the article “On Becoming a Pragmatic Researcher: The Importance of Combining Quantitative and Qualitative Research Methodologies.”
• Consult Table 10.1 (p. 205) in the course text, Research Design, to guide you in polishing your abbreviated mixed methods research plan.

Next, ask yourself the following questions:

• What are your research questions? To what extent can you test them? How would you justify the viability of your questions?
• What are your hypotheses? How would you test them?
• Why would this design be the most appropriate for answering the research questions? Conversely, why would quantitative or qualitative on their own not be appropriate?
  • For a mixed methods design, which design is the primary one? Why is that appropriate?
• What approach would you select for this study (experimental, survey, ethnography, grounded theory, etc.)? Why is that approach the most appropriate one for answering the research questions?
• What theoretical framework or perspective would you use?
• What is your target population? How would you identify and recruit participants? What factors would contribute to determining appropriate sample size? You will not need to calculate sample size for this assignment.
• If appropriate for your plan, what instruments might you need?
• What data collection procedures might you use? Why would those be the most appropriate methods to use? How would that data help to answer your research question(s)/hypotheses?
• How would you ensure quality and reliability of data?
• What are threats to validity? How might you mitigate them?
• How might you analyze the data?
• What are the ethical considerations related to the plan?

The assignment:

• Craft a 2- to 3-page paper in which you do the following:
• • Provide an introduction.
  • Provide a purpose statement.
  • Provide viable research questions/hypotheses.
  • Generate a written research plan that addresses the above questi

Assignment 2: State of America’s Children

In today’s global world, how do the children of the U.S. fare? Are they prepared to compete in the international arena? The Children’s Defense Fund (CDF) is a nonprofit child advocacy organization that provides a voice for children who cannot speak for themselves. The State of America’s Children 2014 is the CDF’s report highlighting some crucial issues affecting our children today. Visit the CDF Web site and read the report:

Children’s Defense Fund (CDF). (2014). State of America’s children 2014. Retrieved from http://www.childrensdefense.org/library/state-of-americas-children/

Select a topic of interest to you from the report’s table of contents (after pulling up the website, you can scroll down to select a topic). Write a research paper on the topic. Be sure to include the following:

• Present the CDF findings on the topic in a table or graph that you create. Note how different populations are affected. For example, you might compare your state to national statistics or compare the top or bottom states on the topic you chose, compare racial/ethnic group data, etc.
• Research the selected topics using at least one additional resource. The data and research publication sections at the CDF Web site offer useful publications.
• Identify and analyze the main issues and discuss them in the context of relevant developmental theory, as well as societal influences. Why is this data and the information you researched important to understand in the context of child development?
• Present your conclusions and support them with research information. What recommendations would you offer to address this issue for future generations?

Write a 4-5 page research paper in Word format. Be sure to include introductory and concluding paragraphs in your paper, and a title page, an abstract, and a reference page. Apply APA standards to citation of sources.

In cases where children are not returned to their biological families, the courts have to find safe, permanent homes for them, including adoptive homes. It is especially difficult in cases where the children have special needs, such as mental retardation or cerebral palsy. In 1997, The U.S. Congress enacted legislation that sought to correct the problems inherent with the foster care system and achieving permanency for special needs children.

Write 2-3 pages detailing the provisions of The Adoption and Safe Families Act of 1997(AFSA).

• Be sure to include the following in your essay:
  • What was the purpose the AFSA?
  • What are some of the programs that the AFSA funds?
  • Who was the major proponent of the AFSA and why?
  • What are some of the changes that the AFSA has effectuated when it comes to foster care and adoption?
  • What provisions does the AFSA have for children with special needs?
