Insurance and reimbursement in the u.s, health care system

The focus of this assignment will be on the foundation and processes that have been established, bringing the U.S. health care system where it is today. You will also consider how current and future plans for financing and reimbursement are currently impacting cost and access of health care.  

Create a 12-15 slide presentation that includes detailed speaker notes for each slide. In your presentation, explore the following points: 

  1. How was health care insurance established in the United States? 
  2. What is the purpose of different health care insurances? (i.e., private, group, self, public) 
  3. What is cost sharing, and how has this impacted health care? 
  4. What reimbursement methods are presently used? (e.g., bundled services, fee-for-service) 
  5. What are retrospective and prospective reimbursements? What are some positives and negatives of each? 
  6. Present and future national health expenditures. Provide a brief overview. How do they influence health care insurance at the present and how will they in the future? 

Do not count the title slide or the references slide when determining whether you have met the required number of slides for this assignment.  

A minimum of three references, in addition to your textbook, are required for this assignment. 

While APA style format is not required for the body of this assignment, solid academic writing is expected, and in-text citations and references should be presented using APA documentation guidelines, which can be found in the APA Style Guide, located in the Student Success Center. 

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

5. Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.

A sample of 75 stocks traded on the NYSE that day showed that 26 went up.

Advance 1 | Marketing homework help

Instructions

Case studies are an important learning strategy in business classes as they provide an opportunity for you to critically analyze events that have taken place in real-life businesses. This develops your critical thinking and research skills as you research the competition and industry in which your business resides with an end goal of formulating a recommendation for the challenges faced by the company. 

Select one of the three case studies listed below, which can be found in your textbook. Evaluate the case of your choice, and respond to each of the questions below using both theory and practical managerial thinking as well as supporting research. 

Option 1: Nike (pp. 30–31)

  1. How has the industry in which Nike resides been doing over the last 5 years? 
  2. What are the pros, cons, and risks associated with Nike’s core marketing strategy? How have they managed to develop a strong customer relationship with their target market? 
  3. Who are the top three competitors of Nike, and what are their advantages/disadvantages with respect to their product/service development? 
  4. Looking at the competitors you discussed in question #3, what would you recommend as being the next steps for these competitors and, subsequently, the next steps for Nike to combat these competitors? 

Option 2: Cisco (pp. 58–59)

  1. How is building a brand in a business-to-business (B2B) context different than that of a business-to-consumer (B2C) market? How has Cisco managed to develop a strong customer relationship with their target market? 
  2. How has the industry in which Cisco resides been doing over the last 5 years? 
  3. Who are the top three competitors of Cisco, and what are their advantages/disadvantages with respect to their product/service development? 
  4. Is Cisco’s plan to reach out to consumers a viable one? Why, or why not? As a marketing manager for Cisco, what would you recommend to be the next steps? 

Option 3: Intel (pp. 59–60)

  1. Discuss how Intel changed ingredient-marketing history. What did it do so well in those initial marketing campaigns? How did Intel manage to develop a strong customer relationship with their target market? 
  2. How has the industry in which Intel resides been doing over the last 5 years? 
  3. Who are the top three competitors of Intel, and what are their advantages/disadvantages with respect to their product/service development? 
  4. Evaluate Intel’s greatest risks and strengths as the industry moves out of the personal computer (PC) era. Identify the next steps that Intel needs to employ in order to maintain its competitive advantage.

Week 10 discussion- 8110 | Human Resource Management homework help

Specific methods of data collection (e.g., surveys, interviews, observations) produce specific types of data that will answer particular research questions, but not others; so here too, as covered in previous weeks, the research questions inform how the data will be obtained.  Furthermore, the method used to collect the data may impact the reliability and the validity of that data.

For this Discussion, you will first consider sampling strategies. Then, you will turn your attention to data collection methods, including their strengths, limitations, and ethical implications. Last, you will consider measurement reliability and validity in the context of your discipline.

Position B: Nonprobability (or purposive) sampling represents the best strategy for selecting research participants.

By Day 4

Post a restatement of your assigned position on sampling strategies. Explain why this position is the best strategy for selecting research participants. Support your explanation with an example and support from the scholarly literature. Next, select a data collection method (e.g., surveys, interviews, observations) and briefly explain at least one strength and at least one limitation. Then, identify a potential ethical issue with this method and describe a strategy to address it. Last, explain the relationship between measurement reliability and measurement validity using an example from your discipline.

Be sure to support your Main Issue Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

Assignment Content

Purpose 

This assignment provides an opportunity to develop, evaluate, and apply bivariate and multivariate linear regression models.

Resources: Microsoft Excel®, DAT565_v3_Wk5_Data_File (Attached)

Instructions: 

The Excel file for this assignment contains a database with information about the tax assessment value assigned to medical office buildings in a city. The following is a list of the variables in the database:

  • FloorArea:       square feet of floor space
  • Offices:       number of offices in the building
  • Entrances:       number of customer entrances
  • Age:       age of the building (years)
  • AssessedValue:       tax assessment value (thousands of dollars)

Use the data to construct a model that predicts the tax assessment value assigned to medical office buildings with specific characteristics.

  • Construct a scatter plot in Excel with FloorArea as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph. Do you observe a linear relationship between the 2 variables?
  • Use Excel’s Analysis ToolPak to conduct a regression analysis of FloorArea and AssessmentValue. Is FloorArea a significant predictor of AssessmentValue?
  • Construct a scatter plot in Excel with Age as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph. Do you observe a linear relationship between the 2 variables?
  • Use Excel’s Analysis ToolPak to conduct a regression analysis of Age and Assessment Value. Is Age a significant predictor of AssessmentValue?

Construct a multiple regression model.

  • Use Excel’s Analysis ToolPak to conduct a regression analysis with AssessmentValue as the dependent variable and FloorArea, Offices, Entrances, and Age as independent variables. What is the overall fit r^2? What is the adjusted r^2?
  • Which predictors are considered significant if we work with α=0.05? Which predictors can be eliminated?
  • What is the final model if we only use FloorArea and Offices as predictors?
  • Suppose our final model is:
  • AssessedValue = 115.9 + 0.26 x FloorArea + 78.34 x Offices

What would be the assessed value of a medical office building with a floor area of 3500 sq. ft., 2 offices, that was built 15 years ago? Is this assessed value consistent with what appears in the database?
