Which of the currently identified health care trends overall are already impacting your employer/organization, or an organization in your city/region in your health care field?

Which of the currently identified health care trends are specifically impacting your sector of allied health, and why?

What emerging health care trends on the horizon may impact your employer/organization and/or your specific allied health sector?

Which of the current or emerging trends do you see as most likely to positively impact your specific role and sector in allied health? Which trends are most likely to negatively impact it? (Examples: wages, job security, educational requirements, etc.)

How will the trends you identify impact safety, risk management, and/or quality improvement policies in your organization/and or an organization in your city/region in your health care field?

You are required to use and cite a minimum of three qualified resources from the readings or the GCU Library in order to complete this assignment successfully.

Due to less business at many car repair workshops during lockdown, some of the workshops had to lay off a number of employees. People were mostly working from home and they were not using their cars. John was among the people that were retrenched. The industry consultants reckon it could take them a while before the business can peak.

John decided to set his own backyard business at home where he could serve the people in his neighbourhood. He then realised that for him to be able to make a viable business, he has to order genuine parts form recognised dealers for the types of cars that he will be working on. The suppliers have computerised their systems and some of the suppliers have closed warehouses where he cannot go and select the motor parts.

John must make his orders online from the car parts suppliers. Besides repairing cars, John also sells parts to other mechanics in the area who are not able to buy from the car parts dealers. John’s clients order the car parts and online. John’s company uses a delivery service to get the car parts to the respective clients who would have ordered online. John uses social media and word of mouth to advertise the businesses.

Suppliers of different car parts deliver the products to his home. He receives different types of delivery notes. Some suppliers send hard copies and some send the delivery notes to be signed online when the order arrives. There are clients from the neighbourhood that can order online and make a payment when they go to John’s house to collect their orders. Source: Makhurane, N. (2020)

Question 8

How does John protect the business systems from software threats?

Stock Inc. has two sites in Pittsburgh that are four miles apart. Each site consists of a large factory with office space for 25 users at the front of the factory and up to 50 workstations in two work cells on each factory floor. All office users need access to an inventory database that runs on a server at the Allegheny Street location; they also need access to a billing application with data residing on a server at the Monongahela site. All factory floor users also need access to the inventory database at the Allegheny Street location. Office space is permanently configured, but the manufacturing space must be reconfigured before each new manufacturing run begins. Wiring closets are available in the office space. Nothing but a concrete floor and overhead girders stay the same in the work cell areas. The computers must share sensitive data and control access to files. Aside from the two databases, which run on the two servers, office computers must run standard word-processing and spreadsheet programs. Work cell machines are used strictly for updating inventory and quality control information for the Allegheny Street inventory database. Workstations in the manufacturing cells are switched on only when they’re in use, which might occur during different phases of a manufacturing run. Seldom is a machine in use constantly on the factory floor. Use the following write-on lines to evaluate the requirements for this network. After you finish, determine the best network topology or topology combination for the company. On a blank piece of paper, sketch the network design you think best suits ENorm, Inc.’s needs.

● Will the network be peer to peer or server-based?

● How many computers will be attached to the network?

● What topology works best for the offices, given the availability of wiring closets? What topology works best for the factory floor, given its need for constant reconfiguration?

The written report requires you to perform a microeconomic analysis of an appropriate economic phenomenon from one of the two economic phenomena provided below. Choose one phenomenon. For your chosen phenomenon, conduct an economic analysis bearing in mind the purpose and remit of this course.
The word limit is 1500 words. As a suggestion, you might want to spend 300 words each on the introduction and conclusion and 900 words on the analysis. However, this may vary depending on your chosen topic and personal style.
An introduction should typically outline the phenomenon you have chosen and highlight its significance. You may present some data to illustrate the phenomenon. Good economic analysis entails identifying (1) the various aspects of the exchange process (the market, the agents involved, the equilibrium outcome), (2) the factors that can affect market outcomes over time and (3) the welfare implications of the exchange outcome and whether there is scope for government intervention. Use graphs, formulae and diagrams where they help your explanations (more rigorous and succinct) compared to words alone. A good conclusion section will provide a look at the big picture, the significance of your findings in a larger context, and even suggest limitations of the models that you have used. Remember this is an economics assignment and therefore you should refrain from writing a report that is general and/or journalistic in nature. Phenomena : Green­House Gas Emissions and Climate Change The issue of green­house gas emissions and climate change has received a lot of media attention over the last decade. While some countries have taken steps to tackle this issue, others have chosen not to respond. Perform an economic analysis of this phenomenon and its welfare implications. Include in your answer the scope of government intervention in tackling this issue.

Assignment #5: Analysis of Variance and Post Hoc Tests
Directions: Using the information from the following scenario, conduct a one-way ANOVA and specify the LSD post hoc test.
The superintendent is continuing to examine the data that has been reported for the district. Another question concerned the differences in performance on high stakes tests. To examine this issue, the superintendent obtained the average scale scores for schools that participated in the high stakes testing for the district and two comparison districts. The following scores were collected:

Superintendent’s district:
298 301 326 313 314 310 310 313 320 304 304 301 299 310

Comparison district 1:
290 288 289 294 307 310 320 274 286 301 280 295 296 310   

Comparison district 2:

302 277 298 306 287 292 309 306 300 285 309 278 290 295   


1. What is the mean scale score for each district?
2. What is the standard deviation of the scale scores for each district?
3. State an appropriate null hypothesis for this analysis.
4. What is the observed or computed value of F?
5. What are the reported degrees of freedom for the Between Groups variance?
6. What are the reported degrees of freedom for the Within Groups variance?
7. What is the reported level of significance?
8. Based on the results of the one-way ANOVA, would you accept or reject the null hypothesis?
9. Based on the results of the LSD post hoc test, identify which districts are significantly different.
10. Present the results as they might appear in an article. This must include a table and narrative statement that reports the results of the one-way ANOVA and LSD post hoc test.
Note: The table must be created using your word processing program. Tables that are copied and pasted from SPSS are not acceptable.

Risk-Based Reimbursement

For your assignment, a primary care physician is often reimbursed by Health Maintenance Organizations (HMOs) via capitation, fee-for-service, relative value scale, or salary. Capitation is considered as a risk based compensation.

In an effort to understand the intricacies involved with physician reimbursement, particularly in an era of health care reform, identify and interview an expert in the field, such as:

Hospital Administrator

Managed Care Organization (MCO) executive

Health care Consultant

Legal Professional

Assumption: MCOs use risk-based reimbursement for primary care physicians.

Ask the following questions in the interview:

What kind of risk do the MCOs assess?

Does risk-based compensation limit the freedom of primary care physicians in any way in terms of patient care? Why or why not?

How does the capitation model of reimbursement work?

Do physicians generally prefer one model over the other? Why or why not?

Why do HMOs prefer the prepaid, monthly premium?

Is pay-for-performance a better model than existing models of compensation? Are there limitations to it as well?

Feel free to add additional follow-up questions for depth and clarification as you see fit.

Create a 4- to 5-page report in Microsoft Word document, analyzing the responses provided (which should be included as part of the report) using the evidence from the literature to help support or refute the responses provided.

Part 1 Below is a production possibilities table for consumer goods (butter) and capital goods (guns).

Graph the data provided in the table using Excel. (Hints: Type your data into an Excel spreadsheet. With your mouse, highlight the data only. Go to insert. Click on scatter. Click on smooth lines chart. Select the line chart. Plot data drawing line.)

Once you have graphed the data, please copy and paste your graph into a Word document so you can complete the rest of the assessment.

Based on the graph you created, complete the following:

·        Analyze the graphed data to develop assumptions, referencing the possibility curve.

o   Identify the specific assumptions that underlie the production possibilities curve.

o   Determine the cost of more butter, if the economy is at point C. What would be the cost of producing more guns? How does the shape of the production possibilities curve reflect the law of increasing opportunity costs?

o   Suppose this hypothetical economy were producing only 1 item of butter and 10 guns, and this was depicted by this production possibilities table and curve. What conclusions could you draw about this economy's resource utilization?

o   Determine whether this economy is able to produce outside its current production possibilities. How might technological changes affect the production possibilities curve? How can international trade allow consumption above its production possibilities curve?
