1. Research in EMS has been very slow to develop over the past decades. Several areas have been identified as barriers or challenges that may limit participation, including the ability to gain informed consent, access to Institutional Review Board (IRB) approval, and the potential to do harm if a known treatment is withheld in order to compare outcomes with treatments of unknown efficacy. Identify two ethical principles that you feel are most at risk when conducting EMS research and explain why you selected them.

   Your response should be at least 200 words in length.

2. Please ensure the following textbook is used in the answer and the answer has the correct number of words excluding in text citation: Youngberg, B. J. (Ed.). (2011). Principles of risk management and patient safety. Chicago, IL: Jones & Bartlett.

Question description

By the mid-20^th century, the United States had become the dominant force in international relations. Some have argued that the United States’ military functions as the world’s “police.” This assignment covers the manner in which this shift occurred and the consequences the United States faces as a result of its status as “policemen of the world.” Using the Internet and reputable news sources, research two (2) real-life international incidents from the past five (5) years in which:

• The U.S. used military action abroad.
• Controversy existed within the American public regarding U.S. involvement.
• Controversy existed within the country or countries affected by U.S. involvement.

Part 1

1. Write a thesis statement that is one to two (1-2) sentences long in which you:
   1. State your thesis on the significance of the current role of the US military, as exemplified in the two (2) real-life international incidents that you have researched. Justify your response.

For the first part of this assignment you will create a thesis statement. A thesis statement is usually a single sentence somewhere in your first paragraph that presents your main idea to the reader. The body of the essay organizes the material you gather and present in support of your main idea. Keep in mind that a thesis is an interpretation of a question or subject, not the subject itself. (Note: Please consult the Purdue OWL Website with tips on how to construct a proper thesis; the website can be found at: https://owl.english.purdue.edu/owl/resource/545/01…

Part 2

For the next part of this assignment you will create an outline of the main points you want to address in this paper. This will serve as the basis for your Assignment 2.2 Final Draft. (Note: Please use the Purdue Owl Website to assist you with this assignment; this website can be accessed at: https://owl.english.purdue.edu/engagement/2/2/55/

1. Write a one to two (1-2) page outline in which you:
   1. Describe the two (2) international events involving the US military from the past five (5) years you investigated that can be traced back to a foreign policy created after the Civil War.
   2. List three (3) aspects of US history since 1865 that have led to the US’s rise as a world super power policeman.
   3. List three to five (3-5) international incidents since World War II where America has taken on a policing role.
   4. List three to five (3-5) driving forces that fueled international policy decisions involving the international incidents you outlined previously. (Consider treaties, exit strategies, elections, wars, etc.)
   5. Use at least three (3) academic references besides or in addition to the textbook. Note: Wikipedia and other Websites do not qualify as academic resources.

Your assignment must follow these formatting requirements:

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

The specific course learning outcomes associated with this assignment are:

• Identify and discuss the different ways that the Civil War, Reconstruction, and Industrialization after the Civil War have shaped America’s history.
• Summarize and discuss the ways that formal policies of government have influenced the direction of historical and social development in the United States.

It is typical for industry to use pay grades and pay ranges in this process.

There are multiple questions in this discussion.

Assume that you are Compensation Manager for a mid-size manufacturing firm.

The firm has recently hired several professional engineers.

Your assignment (as the Compensation Manager) is to write a presentation (in paragraph/letter format) that will explain the compensation structure of the firm.

Understand that your audience has no knowledge of compensation terms or compensation theory. Write your presentation accordingly.

In your written presentation include –

The definition and explanation of pay grades – be sure that your explanations will be understood by your audience

The definition and explanation of pay ranges – be sure that your explanations will be understood by your audience.

Assuming that the mid-point for Engineer I has been set at $40,000, calculate and explain in your presentation the minimum and the maximum pay range for the Engineer I position. The company has determined the range spread should be set at 30%.

Your organization has established four pay grades for professional engineers. All of the new engineers have been slotted into the lowest level or Engineer I. Explain how pay levels increase from Engineer I to Engineer IV. You can make assumptions about the pay differences between the four grades.

Explain how employees in the Engineer I pay grade may progress into the higher pay grades for engineers.

Research and list at least three outside sources.

Question description

After completing Judaism in week 5, Christianity in week 6 and now Islam in week 6, substantively and critically review at least 3 major similarities that exist among Judaism, Christianity and Islam. Why do you think the differences are emphasized more than these differences? What would you say to a religious scholar who concluded that ultimately Jews, Christians and Muslims pray to the same God, even though their beliefs may incorporate some differences? Evaluate that conclusion.

Forum question: DBMS has many functions. What three functions are the most important and why are they most important?

What one benefit of a DBMS would you be willing to give up and why?

2nd to respond to:) This week we have been given instructions to discuss the three most important functions of DBMS. Based off of the book the three most important functions out of the nine: Security services provided by the software, data recovery and lastly, data integrity of course. DBMS is something we have learned in the past, but a refresher is important. DBMS analyzes and captures data within a database by interacting with the system or user. Based off that description of DBMS it is safe assumption that the number one function out of the main three that I have chosen is data integrity because every good database needs data integrity that is what provides accurate and up to date information, without it the database would be useless. The second important function that I picked was security utilized for DBMS. Security services are very essential when it comes to databases, it allows the encryption of data which converts data into a different style which doesn’t allow programs not authorized by the database to view them. This is what makes it so essential to any valuable database. The last function I had picked was data recovery, which is important in every single type of system not only databases. This comes into play when data within the database has been corrupted or some unexpected catastrophe occurred while working on your database. It allows you to retrieve data based on the users saving It or backing it up, which is a great practice for any professional. Out of all the functions, picking one to get rid of is extremely hard to decide because I believe they are all important, but I believe I would chose data replication because it would not be important in my situation because I do not need to have data on multiple databases, which allows users to access it across those platforms.

a) The 2nd order BP transfer function is described by two parameters, namely a and b. Explain what features of the digital filter frequency response are controlled by each of these parameters. 
 b) Suppose it is required to place the center frequency at 0 0.3 and to create a 3 dB. bandwidth that is BW 0.15 . Compute the coefficients for the numerator and denominator polynomials of HBP (z) that will achieve these design criteria. 
 c) An ideal BP digital filter should have a magnitude response that is zero at = 0 and at = and a magnitude response equal to unity at the center frequency. 
Verify that your design in part 2 meets these criteria. 
 d) After the values of a and b have been computed to meet the simple BP digital filter specifications and H(z) has been determined, use Matlab functions to compute and plot the frequency response to demonstrate that all specifications have been met. Then adjust the values of a and b to make the bandwidth half the size as specified originally, but keep the center frequency of the passband in the same location. Plot these new results and compare them with the original specifications. Discuss results. 
 Problem 2 a) A DC blocker filter (i.e. a filter that removes DC offsets from a signal) is nothing more than a high-pass filter with a 3 dB frequency very close to DC. Use a 
sampling frequency of 8000 Hz to design a 1st-order digital DC blocker filter with a 3 dB frequency of 40 Hz and a high- frequency gain of 1. 
 b) In MATLAB, use freqz to calculate the frequency response (magnitude and phase) of the filter designed above. Plot frequency response vs. continuous-time frequency F and obtain hard copies. Also, use the MATLAB command zplaneto obtain a pole/zero plot. You may want to use subplot to put all of the figures on 1 page.

c) Test your filter in MATLAB by generating the following test signal (sampled at 8000 Hz) and passing it through the DC blocker filter using MATLAB’s filter command: x(t) = 6 + 5 cos(2 p × 20 t) + 3 cos(2 p × 500 t) for a time range of 0 to 0.1 second.

Obtain hard copies of both the input and output signals (plotted vs. t). Is the output of the filter as expected, based on the parameters of the filter?

Problem 3.

a) Using a sampling frequency of 8000 Hz, determine the transfer function H(z) for a digital notch filter to remove 400 Hz sinusoidal noise, for each of the following values for a (related to pole magnitude). Scale each filter so that the DC gain = 1:

i) a = 0.866 ii) a= 0.975 iii) a = 0.995

For each case above, calculate the 3 dB notch bandwidth.

b) Test these three filter designs in MATLAB by performing the following tasks. Put all commands in a single m-file and turn the m-file in with your homework.

i) Use freqz to calculate the frequency response (magnitude and phase) of the three filter designs above. Plot frequency response vs. continuous-time frequency F and obtain hard copies for all 3 filters. You may want to use subplot to put all of the figures on 1 page. Also, use the MATLAB command z-plane to obtain a pole/zero plot for all three filters.

ii) Generate the discrete-time test input x[n] by sampling the following CT signal

xc(t)=2cos(2 π ⋅100⋅t)+cos(2 π ⋅400⋅t)

for a time range of 0 to 0.1 seconds and a sampling frequency of 8000 Hz. Plot this test signal and obtain a hard copy. It may look better if you use the plot command rather than the stem command.

iii) Filter the test input using the filter command in MATLAB for all three filter designs. Obtain a hard copy of the filtered output signal for each of the filter designs (use the subplot command).

iv) Generate the ideal filtered signal, yideal [n] =2cos(2 π ⋅100⋅t) sampled at 8000 Hz, and use it to calculate the error signal e[n] = y filtered [n] – yideal [n] for each of the filter designs. Plot all three error signals using the subplot command and obtain a hard copy. The error signal should have a transient part, but should eventually settle to a periodic error.

v) Compare the ideal output to the actual filtered output for all three filter designs. Using the graphs in part (iii-iv) answer the following questions. 1) How quickly does the error settle to a “steady state” for each filter? 2) What is the magnitude of the “steady state” error for each filter? 3) Can you make any generalizations based on your observations above?

Hint: It may help to zoom in on your plots to do the measurements.

Question description

A manufacturing company is thinking of launching a new product. The company expects to sell $950,000 of the new product in the first year and $1,500,000 each year thereafter. Direct costs including labor and materials will be 45% of sales. Indirect incremental costs are estimated at $95,000 a year. The project requires a new plant that will cost a total of $1,500,000, which will be a depreciated straight line over the next 5 years. The new line will also require an additional net investment in inventory and receivables in the amount of $200,000.

Assume there is no need for additional investment in building the land for the project. The firm’s marginal tax rate is 35%, and its cost of capital is 10%.

To receive full credit on this assignment, please show all work, including formulae and calculations used to arrive at financial values.

Assignment Guidelines

• Using the information in the assignment description:
  • Prepare a statement showing the incremental cash flows for this project over an 8-year period.
  • Calculate the payback period (P/B) and the net present value (NPV) for the project.
  • Answer the following questions based on your P/B and NPV calculations:
    • Do you think the project should be accepted? Why?
      • Assume the company has a P/B (payback) policy of not accepting projects with life of over 3 years.
    • If the project required additional investment in land and building, how would this affect your decision? Explain.

• A double-spaced Word document of 2–3 pages that contains your calculation values, your complete calculations, any formulae that you used, and your answers to the two questions listed in the assignment guidelines.
  • You must include your explanation of how you used Excel for your calculations if applicable.
