Social Implications of Medical Issues

Final Paper
To complete this assignment, read through the scenario below and address the specific questions and issues indicated. Review the “Introduction to the Miller Family” document for specific information on each member of the family.
Grandmother Ella has been dealing with cancer for years now and has tried alternative remedies and juicing.  She went into remission for some time, but now the cancer has returned and she is in the hospital.  Her husband, of American Indian descent, has his ideas about what needs to be done as Ella comes to the end of her life.  Ella has her preferences, though she is now so weak that she has given up in many ways.  The family members are each experiencing their own fears and are grieving as they face the loss that will occur as Ella’s life comes to a close.  Ella prefers to die at home and has felt stressed by the discord and discomfort of family members since being hospitalized.
You are the social worker for this case.  You meet this family in the hospital setting as they are considering whether the patient will remain there for her final days or whether hospice and palliative care will be provided for her in her home.
For this assignment, you will:

  1. Synthesize the current research that is relevant to this scenario.
  2. Discuss the cultural or traditional issues that could arise at this time.  Consider how the integration of alternative and complementary medicine and beliefs, mainstream medical practices, and cultural/traditional rituals and practices might create issues and what they might include.
  • Describe how the family might react to the following possible scenarios:
    • Ella wishes to stick with alternative and complementary practices.
    • Ella is coerced into following mainstream medical advice.
    • Ella’s husband insists that, as father and husband, his family traditions should be adhered to.
  • Examine the biological basis for care and describe how the choices for care might affect the other family members with respect to their individual problems, if at all.
    • Son Sam, the alcoholic
    • Daughter Lila, with diabetes
    • Grandson Josh, starting to have drug problems
    • Granddaughter Lucy, bipolar with more entrenched drug problems
    • Daughter-in-law, Sarah’s stress related to her family’s medical issues (nephew with leukemia, brother with HIV, and her father’s perspective that they are all “crazy!”)

Discuss the micro, mezzo, and macro influences affecting both the patient and the diverse family members in this scenario as impacted by Ella’s medical condition and prognosis.

  • What are the pertinent and likely family (micro) conflicts and differences, and concerns that could be encountered?
  • How is the neighborhood and extended family (mezzo) reacting to the situation?
  • If she returns home, what considerations need to be taken into account as part of her discharge plan? Using your local area, research and present the needed or preferred community resources (macro) that would be available to them.  Critique the ability of these community resources to adequately meet the needs of this diverse family’s circumstances.

Discuss the relevant medical issues and the advantages and disadvantages of hospital versus home.  When discussing medical issues in this case, use appropriate medical terminology.  Discuss the psychological and social issues that are present and will possibly be more pronounced at this stressful time.  How has the fact that this illness has been ongoing (chronic) impacted the family? Analyze the current scenario as it pertains to diversity, as well as to cultural, psychological, and social perspectives and influences, taking into account the stories that you have been discussing throughout the course. Discuss the impact of lifespan development on the perspectives of the various members of the family (i.e., their intellect, cognitive abilities, insight, and judgment) as well as their sociocultural perspectives, preferences, understandings, and positions on the situation.

Examining Your Community’s Source of Energy

It is easy to criticize society for not using renewable resources, but in reality, how difficult would this transition be? What processes and procedures would be involved? How would such a transition be made?

The purpose of this assignment is for you to consider what type of energy your neighborhood is currently powered by and what it would really take to convert this source to a renewable one. How much would it take to switch your community to a renewable resource and what would this mean for the environment?

For the assignment, complete the following:

  • Identify three primary types of energy that powers your home as well as all of the homes in your community. You may find this information on your community Web site or the Web sites of the local power companies. For example, your community may use electricity and solar panels.
  • Explain how the sources of energy you identified impact the environment. Consider the following:
    • Does the use of these types of energy resource have a negative impact on the environment in your area?
    • Does your community have nuclear waste to dispose of?
    • Has your community always used these three power sources? If so, how do you feel this has impacted the environment over time?
    • How much of an impact have these sources of energy had on local air and water quality?
  • Considering the current source(s) of power available, determine how much energy your house uses each month. You can find this information on your monthly energy bill.

    Calculate your annual usage for a year. Using this value, estimate the energy consumption for your community. The US Census Bureau is one resource you can use to estimate the number of households in your community.

    You can use the following formulae for this calculation:

    (monthly energy usage) × (12 months per year) = (household energy usage per year);
    (yearly energy estimate for your house) × (estimated number of houses in your community) = (estimated yearly energy use for your community)

    The following is an example of the above calculation:

    52.8 kilowatt hours (kwh) per month × 12 months = 633.6 kwh;
    633.6 kwh × 200 houses in your community = 126,720 kwh

  • Recommend a realistic, renewable resource to power your community, using your calculated power needs. Consider the following sources: hydropower, solar power, wind turbines, and geothermal energy.
    • Which source would be the best for your community?
    • Justify your choice based on the kind of resources that are available, how much power these alternative sources can produce, and your estimated energy demands for the community.
  • Having recommended an alternative power source, conclude by addressing the following:
    • How realistic is this alternative power source for your community?
    • How will people in your community respond to energy conversion? Will they support it or be against it? Give reasons.
    • How expensive would it be to convert to the alternative power source you recommended? How would this new source impact the environment?
    • What organisms would benefit most from this conversion?

Support your statements with appropriate examples and approximately 4–6 credible resources.

Write an 8–10-page paper in Word format. Apply APA standards to citation of sources.

So far in this course, your study has been concentrated on the origin, developmental stages, and many uses of DNA to solve crimes. You have studied how various body fluids such as blood, saliva, and semen are tested, as well as identified the importance of mtDNA and nuclear DNA in DNA profiling. Below are several case studies that were solved using the procedures and analyses studied in class, and the application of the information obtained was used to solve the criminal investigation.

Choose only 1 of the cases listed below and explain how the physical evidence recovered from the crime scene was tested and analyzed to solve the crime.
Case Study 1
A man and his wife were on vacation in Paris. On the way back to the hotel, they were approached by two men with weapons who demanded their jewelry. A physical interaction occurred in which the robbers violently wrestled the man to the ground and removed his watch and rings while his wife tried to run away. The man and his wife were shot and killed. The bodies of the two victims were pulled into an alley. Multiple scratches were on the body of the male victim, and blood was also found on the female victim because the robbers tore the necklace, rings, and earrings off that she was wearing. The two men committing the crime both had previous records for assault and robbery. How were the men convicted of the crime?
Case Study 2

After 10 years of being free, a man was convicted of a rape after DNA evidence was allowed to be used. The female he raped was not able to make an identification, so the attorney had to get permission to do a DNA profile on the suspect. The suspect had lived as a neighbor of the victim, only a few houses away. This man was considered a family friend; however, after the rape incident occurred, he abruptly moved to another state. How was he convicted or exonerated?

Assignment Guidelines
  • Address the following in 4–5 pages :
    • What exactly is DNA profiling? Explain in detail.
      • How it is used to solve crimes? Explain in detail.
    • Regarding your selected case study:
      • What physical evidence would be retrieved from the crime scene?
        • Identify each item of physical evidence, and fully justify your decision to collect it as evidence.
      • What type(s) of DNA tests are required to investigate the crime you have chosen? Explain in detail, and fully support your argument.
        • What is the testing process for the technique(s) used to test each piece of evidence? Be specific, and explain in detail.
    • After analyzing the evidence, explain how the evidence exonerated or convicted the suspects.

Hazardous Materials Management Project

Congratulations! You have just become the safety manager for Podunk, Colorado, and your predecessor left the job a year and a half ago. There has been nobody in the position during that interval. The commitment of the institution to safety is dubious at best, but you are looking forward to starting your new position and making a positive change.
After introducing yourself to the secretary you share with a half dozen other, more senior, people, you decide to focus on hazardous material and hazardous waste issues since you just completed a great college course on those topics. You tour the campus and discover that the following departments and programs are yours to deal with:
ï‚· The biology department has animal dissection, human dissection, a microbiology lab, and a medical laboratory
education program that uses small quantities of a lot of chemicals.
ï‚· The chemistry department has chemicals that have never been inventoried and a new forensics program (as in
CSI, not in college debate).
ï‚· The physics department has high-voltage equipment, lasers, and LEDs.
ï‚· The English department has lots and lots of books and papers, as well as photocopiers.
ï‚· The math department has lots of computers and whiteboards.
ï‚· The automotive technology department has everything pertaining to auto repair, including solvents, asbestos
brake linings, pneumatic tools, waste oil, and cutting and grinding tools.
ï‚· The Massive Arena is one of the original buildings on campus and has a variety of interesting problems, including asbestos insulation, and the building is undergoing a massive renovation.
Respond to each of the following questions:
1. Where do you start?
2. Where should you focus your initial HazCom efforts? In what order do you tackle the rest of the departments?
3. What are the HazCom issues in the automotive technology department?
4. What are the hazardous waste issues in the automotive technology department?
5. What are the HazCom issues in the chemistry department?
6. What are the hazardous waste issues in the chemistry department?
7. With the Massive Arena renovation, who are the people to whom you need to communicate hazards?
8. What are your main concerns with the physics department?
9. What are the hazardous material/waste spill response issues for the university, and how should you prepare for them?
10. Is any HazCom training needed for the English and math departments?
11. What are some resources for finding out how to solve the HazCom issues?
12. You must choose technology or trainers to do the needed training. What are some issues to consider when
selecting these?
13. Due to budget cuts, you have to do the training yourself, and you will use PowerPoint. What are some
considerations when developing your PowerPoint Presentation?
14. How can you evaluate your training to ensure that it is accomplishing your goals?
15. One of the chemistry professors working with some of the automotive technology faculty members, invents a new nonflammable compound that will render obsolete the need for solvents to degrease auto parts. She wants to market the stuff. What needs to be done before it can be marketed, and who should do it?
16. The University decides to partner with the chemistry professor and market this new compound. Due to the lack of flammability, it is a great hit nationwide. They then decide to market it worldwide. What concerns need to be addressed?
17. It turns out that this wonderful new compound makes a really great explosion when used in conjunction with
another chemical. As the University is manufacturing the compound in large quantities and storing it on the
grounds, what concerns do you now have? What experts should you consult?
18. The biology department has been busy as well. The little microbiology lab is large now, and they are working with stronger pathogens. How would you determine the new hazard communication requirements and things that you should do beyond that minimum?
After a tough five years, you have the Podunk University campus running smoothly. Everybody is trained, and your successor will not have nearly as much of a challenge as you did. Congratulations, and best wishes on your next challenge!
Your submission must be a minimum of four pages double-spaced, not including the title and reference pages, and in APA format. Support your answers to the questions with appropriate references and in-text citations.


The study of epidemics is epidemiology. Its primary focus is on the distribution and causes of disease in populations. Epidemiology involves developing and testing ways to prevent and control disease by studying its origin, spread, and vulnerabilities.
As a discipline, epidemiologic research addresses a variety of health-related questions of societal importance. Epidemiologic research methods are used by clinical investigators and scientists who conduct observational and experimental research on the prevention and treatment of disease.
The Cholera epidemic, a case from the 19th century, was enabled by the global movement of people. Having appeared in India in 1817, it spread throughout Asia and the Middle East within a decade. It was reported in Moscow in 1830 and then spread to Warsaw, Hamburg, Berlin, and London in 1831 (Snow, 1855, 2002). When it crossed the Atlantic to reach North America, Cholera gained the notoriety of the first truly global disease.
The modern day world is dominated by free trade and rapid transportation. An unprecedented rate of global interchange of food, consumer products, and organisms—including humans—is occurring. The threat of pandemics in the 21st century has heightened the importance of epidemiology at national and international levels.
Although diseases such as Influenza A (H1N1), Severe Acute Respiratory Syndrome (SARS), Acquired Immunodeficiency Syndrome (AIDS), West Nile Virus, Salmonella, are commonly recognized as epidemics, as they cause large scale disruption of health in populations. The field of epidemiology also addresses epidemics of obesity (Ogden et al., 2007), diabetes (Zimmet, 2001), mental health (Insel & Fenton, 2005), and any other disease that may cause large scale disruption of health in populations.
In general, there are ten stages to an outbreak investigation:

  1. Investigation preparation
  2. Outbreak confirmation
  3. Case definition
  4. Case identification
  5. Descriptive epidemiology
  6. Hypothesis generation
  7. Hypothesis evaluation
  8. Environmental studies
  9. Control measures
  10. Information dissemination

Investigation preparation requires a health crisis manager to identify a team of professionals who will lead the outbreak investigation, review the scientific literature, and notify local, state, and national organizations of the potential outbreak.
Outbreak confirmation requires actual laboratory confirmation of the disease, which may involve the collection of blood, urine, and stool samples from ill people and performing bacteriologic, virologic, or parasitic testing of those samples.
Case definition is the process by which we establish a set of standard criteria to determine who is and is not infected with respect to a specific outbreak; that is, a protocol is developed to determine case patients.
Case identification requires the health crisis manager and team of professionals to conduct a systematic and organized search for case patients based on the standard criteria developed in the case definition phase. Here, it is vital that the team identifies both case patients (individuals already infected), as well as individuals who may have been exposed.
Descriptive epidemiology requires the team to organize the data—who was infected, when, where, etc.—identify frequencies, and perform basic descriptive statistics that may present patterns.
Hypothesis generation requires the team to generate hypotheses as to why the outbreak occurred and compare the situation with previous outbreaks or develop methods to collect additional data.
Hypothesis evaluation requires more in depth statistical tests, including an official epidemiologic study (cohort, case control, etc.) and comparing potential risk factors among those infected (cases) and those not infected (controls).
Additional studies may call for environmental diagnoses requiring collection and analysis of food, water, and other environmental samples. Once all data has been collected and examined, the team will work to implement control and prevention measures by coordinating with community partner organizations.
Finally, the health crisis management team will communicate their findings via an outbreak investigation report that is tailored for the scientific community as well as lay persons. The primary goal of the information dissemination stage is to educate the community about the outbreak and instill the knowledge needed to prevent further outbreaks.
