In light of the COVID-19 outbreak, I have chosen to focus on a Meaning-Focused Coping approach.  I have used this approach to focus on the learning that comes along with the pandemic, discovering why and how it happened, why it has affected so many and how it has spread, what is and could be done to combat it and I am also applying my current knowledge in public health to try to see all sides of it.  I have also used this time to realize what is really important in my life and have been able to do some self-growth as well which will help me come out stronger on the other side.

To me, resilience is based off of first and foremost the actions of one's self. The decisions that a person makes to deal with a situation make or break their resilience in the future. I have chosen to provide resilience for myself during this time by focusing on staying calm, following the realistic and scientific information without drawing false conclusions, making a new plan for how I will finish the semester strong online remembering to practice self-care while at home.

One specific action that I am taking to prevent the spread of COVID-19 in my community is that I am taking the 14 day home quarantine seriously, since I traveled outside of Alaska for the first week of Spring Break, I have stayed at home and have not come in contact with anyone else. This is very important to be able to flatten the curve of people being infected everyday.

A 1.458-g sample of a solid, weak, monoprotic acid is used to make 100.0 mL of solution. 40.0 mL of this solution was titrated with 0.07942-M NaOH. The pH after the addition of 16.55 mL of base was 2.94, and the equivalence point was reached with the addition of 46.63 mL of base.

a) How many millimoles of acid are in the original solid sample? Hint: Don't forget the dilution.

b) What is the molar mass of the acid?

c) What is the pK_a of the acid?

"Discuss whether free market is necessarily efficient. Give some examples to illustrate the
limitations of government interventions in restoring the market efficiency. Some economists advocate market-based solutions, discuss its merits over command-and-control policies."
Please give 3~4 practical examples with your own word and apply micro-economic theories and concepts to these examples.

A study was perform in the Albuquerque, New Mexico metropolitan area to evaluate the diagnostic accuracy of Prostate Specific Antigen (PSA) testing as a screening tool for detecting prostate cancer in community practice. Subjects were 2,620 men 40 years and older undergoing (PSA) testing and prostate biopsy. A total of 1,932 men tested positive with the initial PSA testing and among them cancer was detected in 800 subjects with a subsequent prostate biopsy. In addition, 130 cases of prostate cancer were detected among men who screened negative with the initial PSA test.

a) Using the information above, create a 2x2 table to assess the accuracy of the test.

b) Calculate and interpret the sensitivity of the PSA test.

c) What will be the specificity of this screening test? Calculate and interpret.

d) Calculate and interpret the predictive value positive of the PSA test.

e) Calculate and interpret the predictive value negative of the PSA test
