An industry analysis of innovative industries in the US.
What is the innovative industry?
Why the innovative corporate size ranking and competitiveness of private companies are always better than public innovative companies?
What type of interventions improve adherence to recommendations on nutritional intake?
Select and analyze an example of a criminal justice policy that comes in conflict with constitutional protections. What is the conflict? How should it be resolved?
Criminal justice policies are always a delicate balance between personal liberty and the desire to reduce crime.
2)Define the income elasticity of demand? What information does it provide? How is it calculated?
3)Define the cross-price elasticity of demand? What information does it provide? How is it calculated?
4)What is total revenue? How is it calculated?
5)Define elastic, inelastic, and unitary elasticity means. How are these related to total revenue? Explain your answers.
6)With respect to the price elasticity of demand, construct a graph using the data in Figure1. Illustrate the ranges on the demand curve that indicates elastic, inelastic, and unitary elasticity. Explain your answers. Enter
non-numerical responses in the same worksheet using text boxes.
7)Calculate the total revenue for each level of demand and post into the table, Figure 1. (Copy and paste this table into the Microsoft Word document that will form part of your submission.)
8)Using the midpoint formula, calculate the price elasticity coefficient for each price level, starting with the coefficient for the $4 to $6 level. For each coefficient, indicate each type of elasticity: elastic demand, inelastic demand, or unitary demand. Post your answers to the table, Figure 1.
9)Assume that the income of consumers changes by 10%, and as a result the quantity demanded for Good A changes by 8%. What is the income elasticity of demand for Good A? What does this mean for your company?
10)Assume that the price of competing Good B decreases by 5% and as a result, the quantity demand for Good A decreases by 8%. What is the cross-price elasticity for your product? What type of goods are Good A and Good B?
In Community X (population 20,000), an epidemiologist conducted a prevalence survey in January of 2012 and reported an HIV prevalence of 2.2%. Over the next 12 months, the department of health reported an additional 50 new HIV cases between February 2012 and January 2013. The total population stayed constant at 20,000.
Part 1
How many people had HIV in January 2012? Present or describe the formula you used to arrive at your answer.
Calculate the incidence rate assuming no HIV-related deaths over the 12-month period. Present or describe the formula you used to arrive at your answer. Be sure to clearly indicate the numerator and denominator used in your calculation and include an appropriate label for the rate.
In a summary of 200-250 words, interpret the results and discuss the relationship between incidence and prevalence. Discuss whether or not the epidemiologist should be concerned about these new HIV infections, assuming a previous incidence rate of 0.5 per 1,000 person-years prior to this updated risk assessment.
Part 2
A rapid test used for diagnosing HIV has a sensitivity of 99.1% and a specificity of 90%. Based on the population prevalence of 2.2% in 2012, create a 2×2 table showing the number of true positives, false positives, false negatives, and true negatives. Calculate the positive predicative value and negative predictive value for this test. Refer to the “Creating a 2×2 Contingency Table” resource for guidance.
In 200-250 words, discuss whether or not the epidemiologist should recommend this test as part of a universal HIV screening program.
