IRB DNP Project Screening Form

/in /by

A​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​fter reviewing the recording , reflect on the IRB prescreening process by answering the following questions: Concisely describe the process for the IRB prescreening review at Chamberlain University? What barriers could you face as you progress through the IRB presc​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​reening?process? Will you need to gain IRB?approval from your organization? No is does not. Elaborate… If you do not need a site IRB review, have you arranged to get a letter from your organization that confirms you do not need IRB approval? Yes I did..elaborat​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​e

Isotope that decays one daughter isotope

/in /by

  1. First, for each parent isotope that decays one daughter isotope is created.
  2. Secondly, it is important to notice in the rate expression that the number of decays is not a constant function of time (say for example the way a second is always 1/60th of a minute). Rather, the number of decays over a given time period changes with the number of parents present (simple example: 1/2 the students leave every 5 minutes during this lecture). Thus, decay is not a linear function of time, rather it is ‘curved’. The concept of half-life (t 1/2) is an important concept to remember. Half-life is the time required for half of the substance to decay to a stable daughter.

Given these basic points students can follow the construction of a Parent and Daughter vs. Time graph. This graph illustrates two major points regarding radiometric dating:

  1. First, the point of intersection between the parent and daughter curves (both have equal no. of atoms) illustrates the concept of a half-life.
  2. Second, this exercise graphically represents the change in Parent-Daughter ratio with time. With every half-life, there will be less parent atoms and correspondingly more daughters.

Oil exploration firm is currently searching for oil

/in /by

  1. An oil exploration firm is currently searching for oil. Their probability of finding oil this year is 77% and if they hit oil we expect the stock to return 64%. If they do not hit oil we expect the stock to return -14%. What is the standard deviation of the return of the stock?
    Give your answer to two decimal places (9.99%)
  2. A company had free cash flows of $759 million last year. Free cash flows are expected to grow at 3.9% per year. The WACC for the firm is 10.1%. They currently have $9.6 billion in debt outstanding, and have 242 million common stock outstanding. The company has 82 million preferred stock outstanding, that currently trade at $12.64.
    What is the estimate of the stock price based on the firm valuation model?
  3. A company had free cash flows of $722 million last year. Free cash flows are expected to grow at 2.5% per year. The WACC for the firm is 7.3%. They currently have $8 billion in debt outstanding, and have 182 million common stock outstanding. The company does not have any preferred stock.
    What is the estimate of the stock price based on the firm valuation model?
