As you know from your pre-class work, W.T. needs to determine how much he’ll charge the customers of My Assistant. Keep in mind that he’ll need to (1) cover costs and (2) earn a profit so he can be paid.

Part 1

We’ve already done quite a bit of work on projected costs for My Assistant, so pull out your notes from Packet #2. To recap, W.T.’s planning on the following:

Considering his analysis of similar services and to keep things simple, W.T. plans to price all jobs the same and charge $15 per job. Because of this flat rate, he anticipates he’ll likely need to create different types of “jobs”. For example, purchasing a list of items at the grocery store would be one job, while a bundle of 2-3 small errands such as picking up dry cleaning and prescriptions, might be considered one job. We’ll deal with those details later. For now, assume that all jobs are priced at $15 each and all have the associated variable expenses listed above.

Because this will be a new business, W.T. knows business will likely be slow at the beginning. Complete the following table assuming W.T. completes 10 jobs in a single month.

Part 2

Yikes! He’ll clearly have to complete more than 10 jobs. W.T. needs to be able to at least cover his costs. Still using the preliminary estimates provided, how many jobs would W.T. have to complete to break even? What would that be in dollars?

(1) Contribution margin:

(2) Break-even point in units:

Note: W.T. won’t be paid if he only completes part of a job.

(3) Break-even point in sales:

Check your work:

Question: Why is breakeven profit not exactly $0?

The goal of the project is to introduce the process researchers use to design an observational study. Researchers at reputable institutions are required to create a detailed proposal before embarking on an experiment or observational study to an Institutional Review Board (IRB). An IRB is:

a type of committee that applies research ethics by reviewing the methods proposed for research to ensure that they are ethical. Such boards are formally designated to approve (or reject), monitor, and review biomedical and behavioral research involving humans. They often conduct some form of risk-benefit analysis in an attempt to determine whether or not research should be conducted. The purpose of the IRB is to assure that appropriate steps are taken to protect the rights and welfare of humans participating as subjects in a research study. https://en.wikipedia.org/wiki/Institutional_review_board

Ultimately the IRB needs the researcher to show that the experiment or study is useful (it will contribute to the scientific understanding of some process) and relatively safe

Step 1

Articulate a hypothesis to test. Pick something that is interesting to you in an area that you know a lot about. Your study must have human subjects. The hypothesis needs to conform to one of the following methods:

1. two-sample test for mean,

2. two-sample test for proportion,

3. chi-squared goodness of fit test,

4. or chi-squared test of independence.

Don't describe the test with mathematical notation yet. Describe it in several sentences. Explain why your test is interesting and important to you. Outline any ethical considerations and how you would deal with them. Would you need to obtain "informed consent"?

Don't worry about whether you can carry out the test. For instance suppose you want to poll people at your work, don't worry about whether your manager would let you.

Step 2

Specifically identify your populations.

Step 3

Explain your sampling procedure. Make sure to address the following.

1. How will you make sure that the sample is representative?

2. How will you make sure the sample isn't biased?

3.How will you make sure you are sampling the correct people?

4. What sampling method will you use (cluster, stratified, etc.)?

Step 4

Explain what data you will collect and how.

1. What size will your sample need to be?

2. How would you generate a random sample?

3. What will you do with your sample? Will you ask them questions if so what questions? Will you measure the subjects if so what measurements?

Step 5

What method will you use to analyze your study?

1. State in mathematical notation your exact hypothesis.

2. Why is the method you choose appropriately to use?

Step 6

What new knowledge will your study contribute to society? How is it important?

Critical Thinking Case Study RR, a 22-year-old college student, is in the wellness clinic with her 3-month-old daughter and her 13-year-old sister. They live with RR’s grandmother, who is 68 years old. RR requests immunizations for her daughter and asks if there are any immunizations she and her sister need.

1. RR says her daughter needs her “regular shots.” The infant received her first hepatitis B vaccine while in the newborn nursery but has not had any shots since coming home. Against what vaccinepreventable illnesses should the nurse plan to vaccinate this infant today?

2. RR is worried that she will need to start her immunizations over because “she’s so far behind.” How should the nurse respond to her concern? When would her infant be due for another series of immunizations?

3. Which vaccines is RR’s daughter due for today?

4. RR reports she is afraid the baby will have a reaction. Compare the mild side effects with the more severe allergic reactions. What is the best way of allaying RR’s fears?

5. The nurse asks RR about her vaccine history. RR says she had her “baby shots” a long time ago but did not keep her personal vaccine record; however, she remembers receiving a flu shot 2 years ago. What immunizations will she need at this point? How can she best keep track of her immunizations?

6. RR informs the nurse that she is a college freshman and just received an email informing her that there is a campus-wide meningitis outbreak. She doesn’t live on campus and asks the nurse if she needs a meningitis shot anyway. Identify the manifestations of this vaccine-preventable disease.

7. After administering RR’s meningitis vaccine, RR’s 13-year-old sister mentions that she heard that high school students should get a vaccination for human papillomavirus (HPV). She wants to know if she should get one or if it is too late. Who is eligible to receive the HPV vaccine, and what assessment questions would the nurse ask? What type and dosage of vaccine would the nurse administer?

8. RR appears relaxed and comfortable during the visit. However, she states that she is worried about her grandmother’s health because her grandmother has diabetes and high blood pressure. RR wants to know if her grandmother should get any immunizations or if those would just make her sick. Identify which vaccine-preventable diseases and vaccines should be given.

9. After the visit, how does the nurse ensure that the vaccines were safely administered?

ENG 259 - Technical Writing Newtown Creek Memo Assignment: Rhetorical Context: You are a petroleum engineer working for Enviro-Clean, a company dedicated to cleaning up polluted waterways in urban areas. In March 2017, Enviro-Clean won an $8.5 million New York city contract bid to clean up Newtown Creek, a polluted waterway located on the border between Brooklyn and Queens. In April 2017, you were assigned to the position of Lead Project Manager responsible for overseeing the direction of Project Newtown Creek. In this role, you have been directing three teams of subordinates so that Enviro-Clean can begin the actual clean-up efforts, which the company’s Board of Directors hope will take place before or by September 2018. By October 2017, several months after taking on your project manager role, you have successfully been interacting with your three teams of subordinates. (There were some glitches here and there but, overall, your interaction with the teams has been effective and productive.) You are confident that the clean-up efforts can actually begin in July 2018. Under your supervision, Team A, comprised of other petroleum engineers and a few Human Resources staff members, has been able to subcontract Pure H20, a highly qualified wastewater treatment engineering firm to test and treat the polluted water in the waterway throughout the duration of the clean-up efforts. Team B, mostly Quality Assurance professionals and company attorneys, was able to secure all the required city and state permits necessary to build your clean up facilities on the creek. Team C, comprised of Enviro-Clean mechanical engineers and outside mechanical engineering consultants, was able to design and build the necessary equipment your company will need to perform the clean-up efforts. On October 31, 2017, during a project planning meeting, Susan Canalski, Senior VP of Project Planning, tells you that the Board of Directors will probably be requesting a detailed progress report from you in the coming weeks regarding Project Newtown Creek. In the meantime, she asks you to send her a short memo (less than one page) that gives her a preliminary update discussing what’s been accomplished thus far regarding Project Newtown Creek. Task: Write a clear, concise memo offering an update concerning what’s been accomplished thus far regarding Project Newtown Creek. As you write, consider the above rhetorical information, and decide what should be included and what should not be included. Make sure you are being comprehensive enough without being unnecessarily wordy. Make sure your dates and target audience reflect the rhetorical context. Consider the visual elements of the memo as well as the verbal and consider using bullets to highlight the most important information. Make sure the memo is easy to read and make sure you proofread, proofread, proofread.

What are all the strengths and all the weaknesses related to the internal validity of the research design in Item 3. (10 points) a. Strengths b. Weaknesses To measure reciprocal resource dependence of state agencies and nonprofit organizations, 14 Likert-type scales were constructed with a number of items to which the respondent indicated intensity of agreement or disagreement on a six-point scale. Response categories were strongly disagree, generally disagree, disagree a little, agree a little, generally agree, strongly agree. The conceptual anchors of each scale were (1) independence and (6) dependence. That is, higher scores represented greater dependence in the area being assessed. Three scales (importance, alternative availability, and pressure) measured the dependence of state agencies on nonprofit organizations for resources. Three parallel scales measured the same dimensions for resource dependence in the other direction, that is, the dependence of nonprofit organizations on state agencies for resources. Items were predominantly attitudinal; some were behavioral. The following items are samples from the importance, alternative availability, and pressure scales, respectively. S1. State agencies often use ideas from nonprofit organizations to formulate policy recommendations. N1. Nonprofit organizations often use ideas from state agencies lO formulate policy recommendations. S2.There are certainly other supporters of agency interests as valuable as nonprofit organizations. N2. There are certainly other supporters of nonprofit organizations' interests as valuable as state agencies. S3.Agencies are in no position to force nonprofit organizations to implement their programs. N3. Nonprofit organizations are in no position to force agencies to fund their programs. Scale scores were the average of the item scores. Table 3 reports reliability results for the six scales. Alpha reliability coefficients are listed in bold-face type. Discriminant validity may be measured by the inter-scale correlation coefficients shown on the diagonal in that table. Table 3: Reliabilities of State and Nonprofit Scales Scale Reliability State Importance .67 State Alternative Availability .73 State Pressure .63 Nonprofit Importance .70 Nonprofit Alternative Availability .70 Nonprofit Pressure .75 The remaining eight scales were divided, four each for state departments and non-profit agencies, into individual service areas. These were arts, health, developmental disabilities, and human services. The first set of four examined dependence of the state departments on nonprofit agencies in the four areas; the second set of four scales assessed the dependence of nonprofits on state agencies in the same four areas. The average of the three individual scale scores measuring state agency dependence on nonprofit agencies became Dsn in the model. The average of the three individual scale scores measuring nonprofit agency dependence on state agencies became Dns. These reciprocal resource flows, understood together, became the basis for a g e n e r a l model of resource dependence between sectors.
