State laws vary in the degree to which employers are allowed to have access to information about the criminal history records of potential employees. In particular, Florida allows employers very open access, Michigan provides access for only some employers, and Tennessee provides access to no employers.  Employers sometimes use the criminal history records to avoid hiring ex-offenders.  As a result, ex-offenders in states where it is easier to find out who is an ex-offender have worse employment outcomes (lower wages) than ex-offenders in states with more restrictive laws.  To test this hypothesis, a researcher surveys 50 ex-offenders each in Florida, Michigan and Tennessee.  The average hourly wages for these ex-offenders are listed below by state.

n_Florida= 50                                          n_Michigan= 50                                        n_Tennessee= 50

The grand mean is $8.51

There are three theories that explain exchange rate behaviour, two of these deals with how inflation rates affect the exchange rate. They are purchasing power parity (PPP) and International Fisher Effect (IFE).

(a) In reality, PPP does not hold. Even PPP holds, this does not consistently occur. Give two major reasons why PPP does not hold consistently. Explain in detail.

(b) Assume the spot exchange rate of Singapore dollar to US dollar is US$0.7420/S$. The one-year interest rate is 0.3% in U.S. and 6% in Singapore. What would be the spot rate in one year according to IFE?

Like all viral pathogens, severe acute respiratory syndrome coronavirus 2, or SARS-CoV 2, requires a cell surface receptor in order to invade a given host cell. For SARS-CoV 2, this receptor is actually the enzyme Angiotensin Converting Enzyme 2, or ACE2. ACE2 is responsible for downregulation of the Renin-Angiotensin-Aldosterone System by deactivation of Angiotensin II. Explain the RAAS in detail, including the roles played by kidneys and the lungs, and then explain what effects using recombinant human ACE2, or rhACE2, to treat acute respiratory distress syndrome could have on blood pressure.

Cane, the sole owner of a small business, has a large piece of used farm equipment for sale. He offers to sell the equipment to Bill for $10,000.

Discuss the legal effects of any two (2) of the following events on the offer:Use the Internet to research the law in your home state on the purchase of personal property. Discuss the law in your home state, and compare and contrast it with the Statute of Frauds.

Cane dies prior to Bill’s acceptance, and at the time he accepts, Bill is unaware of Cane’s death.

The night before Bill accepts, a fire destroys the equipment.

Bill pays $100 for a thirty-day option to purchase the equipment. During the period, Cane dies, and Bill accepts the offer, knowing of Cane’s death.

Bill pays $100 for a thirty-day option to purchase the equipment. During this period, Bill dies, and Bill’s estate accepts Cane’s offer within the stipulated time period.

Assume that for one of the events you selected, the negotiation of the contract occurred online. Explain how cyber-law would affect the negotiation of the contract.

Use proper APA formatting for at least one (1) primary source to support your response.

(i) State the definition of the theory of liquidity preference.

(ii) How does the theory of liquidity preference explain downward-sloping aggregate-demand curve? Explain your answer in both words and diagrams.

Project 7:   Acids and Bases

A neutralization reaction depends on the transfer of a proton, hydrogen, from one substance to another. The substance that donates the proton is an acid. That which accepts the proton is a base. pH is a measure of the molar concentration of hydrogen ion in a solution. The strength of an acid is determined by its ionization potential, or the relative amount of the hydrogen ion present in a compound that can be donated. If an acid can donate most of its hydrogen and become completely, or almost completely, ionized then it is a strong acid. Strong acids have a low pH, in the 1 – 2 range. A small potential proton donation results in a weak acid and the pH will be in the 3 – 6 range. A neutral solution, one in which the molar concentrations of hydrogen and hydroxide are equal, has a pH of 7. A predominance of free hydroxide ion in a solution indicates a base. A weak base has a pH of 8 – 11 and a strong base has a pH in the range of 12 – 14.

In order to test the hydrogen ion concentration of a solution, it is often convenient to use a substance that will change color as a result of the ion being present. Such a material is called a chemical indicator. In this experiment you will use an indicator made from red cabbage. Red cabbage works because it contains a water-soluble pigment called anthocyanin that changes color when it is mixed with an acid or a base. The pigment turns red in acidic environments and bluish green in alkaline (basic) environments. The following table shows the color corresponding to approximate pH ranges.

Procedure:

1. Tear, or cut, cabbage leaves into fairly small pieces and place them in a glass bowl.

2. Pour boiling water over the leaves to cover them completely, then let sit until the liquid is a purplish color and the solution has cooled. Remove the leaves by filtration or decantation saving the juice.

3. Pour approximately 2 Tablespoons of cabbage water into each of eight small colorless containers. Place thecontainers on plain white paper. Set one cup aside as your standard.

4. To each of the other seven containers, add a few drops of your testing solutions. Suggestions for testing solutions include, but are not limited to, lemon juice, vinegar, apple juice, baking soda, shampoo (preferably clear), conditioner (preferably clear), hand sanitizer, ammonia, laundry soap, cream of tartar and orange juice. When testing a solid material, dissolve it in water and then add a few drops of the resulting solution to a container of indicator.

Results:

1. Write the name of the solution that you tested in the appropriate box of a table.   

2. If you dilute your test solution with water before adding it to the indicator does it change the pH? Why, or why not?

3. In terms of an acid base reaction, why is Alka-Seltzer used to treat stomach aches?

4. What is acid rain and how is it a problem to oceans and rivers? (A one paragraph answer is sufficient.)

5. Include a labeled picture of your experimental results.
