Epidemiology

Epidemiology is the study of how often diseases occur in different people and why they occur. Epidemiology can help us track diseases and find out when an outbreak is occurring or if a disease is decreasing due to a public health interventions.

Given the above information, what do you think is the role of the epidemiologist in data collection? What is John Snow’s (1854) influence on the foundation of modern epidemiology? What are the current 10 leading causes of death for all races/ethnicities? What, according to you, are the five most important human diseases associated with stress? Justify your answers with appropriate research and reasoning and comment on the postings of at least two peers as to whether you agree with their view on the diseases associated with stress.

Homeostasis—The Importance of Being in Balance

When many people think of homeostasis they think of their body being in balance or the flight or flight response. Homeostasis is the maintenance of physiological conditions required to maintain the life of the organism. Cannon (1932) has come up with some theories on homeostasis. What are Cannon’s (1932) theories on homeostasis? What is the World Health Organization’s (WHO’s) definition of engineering methods, also known as engineering controls?

There are five key engineering methods developed to reduce or eliminate the spread of infection and disease. How effective do you think these methods have been? Of these methods, which one has been the most effective and which one the least effective? Why? Justify your answers with appropriate research and reasoning

Homelessness in America is a persistent, complex, and widely-occurring problem that incorporates many economic, social, and psychological dimensions

/in /by

Homelessness in America is a persistent, complex, and widely-occurring problem that incorporates many economic, social, and psychological dimensions. After years of war and economic decline, the ranks of the homelessness have grown to include families with children (35{0e601fc7fe3603dc36f9ca2f49ef4cd268b5950ef1bbcf1f795cc00e94cdd119}), military veterans (23{0e601fc7fe3603dc36f9ca2f49ef4cd268b5950ef1bbcf1f795cc00e94cdd119}), children (25{0e601fc7fe3603dc36f9ca2f49ef4cd268b5950ef1bbcf1f795cc00e94cdd119}), persons fleeing domestic violence (30{0e601fc7fe3603dc36f9ca2f49ef4cd268b5950ef1bbcf1f795cc00e94cdd119}), and the mentally ill (20-25{0e601fc7fe3603dc36f9ca2f49ef4cd268b5950ef1bbcf1f795cc00e94cdd119}) (National Student Campaign, 2012). Additionally, the number of homeless young adults, aged 18 to 24, is growing, giving homelessness a new face (Saulny, 2012).

With regard to the problem of homelessness, some people perceive a call for greater human compassion, while others demand more effective social policy and more comprehensive public health services. Still others insist on greater individual responsibility and more respect for the needs of business, reinforced by aggressive criminal justice responses.

Your paper will examine a broad range of private and public responses (e.g., laws, policies, programs, and individual behaviors) to the problem of homelessness in America.

  1. You will examine five to seven such responses in depth from the perspectives of virtue ethics and distributive, commutative, and retributive justice.
  2. You will summarize the responses and identify the consequences of each response for the problem of homelessness.
  3. You will evaluate competing and conflicting views about the appropriateness of private and public responses to the problem of homelessness and present a balanced conclusion about the justness of each response.
  4. Finally, you will draw an overall conclusion about whether, 30 years from now, the next generation of Americans will view today’s responses to homelessness as just.

Start your research by reviewing the PDF document, Recommended Resources for the Final Paper. Use these resources to gain familiarity with various aspects of the homelessness problem and a range of responses to it. Some of the websites list other research based resources that contain in-depth information that can also be utilized in your paper. Also, use the Ashford University Library to find scholarly articles that are relevant to the specific responses to homelessness that are the focus of your paper.

The paper must be eight to ten pages in length (excluding the title and reference pages) and formatted according to APA style. You must use at least five scholarly resources (at least two of which can be found in the Ashford University Library) other than the textbook to support your claims. Cite your sources within the text of your paper and on the reference page. For information regarding APA, including samples and tutorials, visit the Ashford Writing Center, located within the Learning Resources tab on the left navigation toolbar.

Writing the Final Paper

The Final Paper:

  1. Must be eight to ten double-spaced pages in length, and formatted according to APA style as outlined in the Ashford Writing Center.
  2. Must include a title page with the following:
    1. Title of paper
    2. Student’s name
    3. Course name and number
    4. Instructor’s name
    5. Date submitted
  3. Must start with a short introductory paragraph which includes a clear thesis statement (your answer to the question: Will the next generation of Americans view as just, today’s response to homelessness?). The thesis statement itself is just that – a statement of what your essay demonstrates. The thesis is not a question, and it is not a summary of the topics discussed. You should avoid using the first person voice, avoid sentences like “This paper will show that…” and avoid asking questions with your thesis. Rather, your thesis should make declarative statements.
  4. Must address the topic of the paper with critical thought.
  5. Must end with a short paragraph which includes a conclusion. The conclusion and thesis must be consistent.
    1. Your paper must logically develop the thesis in a way that leads to the conclusion, and that development must be supported by facts, fully explained concepts or assertions, and persuasive reasoning.
  6. Must use at least five scholarly resources, including a minimum of two from the Ashford University Library.
  7. Must be in your own words. While brief quotes from sources may be used, altogether the total amount of quoted text must be less than five percent of the body of your paper.
    1. When you use someone else’s words, they must be enclosed in quotation marks followed by an APA in-text short citation (author, year, page number) to your source. The in-text citation must correspond to a full APA citation for the source on the reference page at the end of the paper.
  8. Must document all sources in APA style, as outlined in the Ashford Writing Center.
  9. Must include a separate reference page, formatted according to APA style as outlined in the Ashford Writing Center.

Since topics may vary, formatting will as well; however, students will need to provide:

� Abstract

� History of the disease

� Symptoms of the disease

� The cause of the disease (and how/when the cause was discovered)

� Method to spread the disease (if chronic disease, populations most affected in the US)

� Methods to contain the disease

� Number of people infected or affected today (number of deaths, if applicable); may also use graphs and tables

o Use descriptive epidemiology concepts

� Public health costs (i.e. local, federal, hospitalizations, nursing, hospice)

How a cell phone contributes to driving hazards

/in /by

The effects of texting while driving have been a matter of great interest lately. 50 percent of drivers between the age of 16 and 24 confessed to having texted while driving. Two thousand young drivers die annually from accidents related to texting. In May 2009, there was a much publicized car crash in Boston where a driver crashed texting his girlfriend. On September 12, 2008, A Union Pacificfreight train and a Metrolink commuter train had a collision in Los Angeles, California. The accident claimed the lives of 25 commuters. Investigations by National Transport Safety Board (NTBS) found out that the Metrolink train operator had been texting while operating the train. The investigation concluded that the engineer might have been distracted by numerous texts he sent while on duty.

How a cell phone contributes to driving hazards

According to a research from the University of Utah, driving while using a phone lowers a driver’s reaction time to levels observed in drunken individuals. Cell phone results in thousands of road accidents and car crashes annually since our brain have difficulty managing several tasks simultaneously. Using a hand held phone while driving increase car crash risks by up to four times.

When people have conversations, they often have to give the information they get due consideration. This concentration on the information they receive from conversations competes for the brain capacity and can cause impaired decisions.

 

Latest studies show 8 percent of drivers drive while using cell phones; however, this statistics is expected to rise. Phone conversations take driver’s concentration off the road. Not withstanding the use of either handheld or hands-free phones, the driver loses focus on his driving duty impairing the driver’s judgment. Phone conversations leads to driving impairments as shown below;

  1. Inattention blindness: – drivers engaged in phone conversations do not monitor everything they see on their environment. This is a potential cause for harm since the driver is not able to identify a potential danger or respond to emergency circumstances effectively. Research shows that drivers using mobile phones while driving fail to see half of the objects on their driving setting.
  2. Slow reaction time: – drivers using cell phones while driving experienced slow response to emergency situations on the road.
  3. Sticking to lanes: – drivers engaged in phone conversations have problems sticking to their lanes. Using cell phones while driving fast may cause weaving on the lanes leading to crashes.

 

Most drivers admit to the potential harm involved in using cell phones while driving; however, confessed to using phones while driving.
