Create a simple 0, 1 integer model for a situation or problem you face in your life. Is there an optimal solution for your problem? What type of model would you use to create an optimal solution? Explain.

In June 2008, the Journal of the American Academy of Dermatology reported on the use of an intermittent therapy for flare prevention and long-term disease control of eczema (red, inflamed, itchy skin). Eczema is a chronic skin disease that affects about 10% to 20% of infants and about 3% of adults and children in the United States. Researchers wanted to determine whether intermittent dosing with a specific topical inhibitor is effective in preventing eczema flare-ups in patients with stabilized eczema. Initially, 383 adults and children with moderate to severe eczema were treated with daily doses of the topical inhibitor. After 16 weeks, 197 were disease free and admitted into the maintenance phase of the study. These patients were randomized to a 3-times-weekly treatment with either the topical inhibitor or a placebo for 40 weeks. All tubes of ointments (topical inhibitor and placebo) were packaged in identical boxes and labeled “for investigational use only.” Then the packages were sealed with tamper-proof seals and shipped. Neither the researchers nor the patients knew who received the topical inhibitor or who received the placebo. During the maintenance phase researchers tracked the number of flare-free days for each patient.

Which of the following design features contributes to double blinding?
A.Randomization of patients to one of two groups

B. Distinguishing the packaging for both treatments

C. The number of flare-free days for each patient

For this discussion question you are gong to pick a tax that you or someone you know has to pay and do a little research to determine where that tax goes and what it pays for. You can choose any federal, state or local tax (although state or local taxes may be easier). Once you've picked a tax, make a post below and answer the following questions:

What is the tax you picked?

What type of tax is it? (e.g. excise, percentage, etc.)

Why does this tax exist and where does the tax revenue go? What does the tax fund? (for this one you might have to do a little research)

Based on what the tax funds, do you think it is a tax we should have? (i.e. do you think the tax revenue should go where it does? somewhere else? should the tax be abolished? etc)

NOTE: In your post please include links to any sources where you found information about the tax you are looking at (county web pages, etc.)

A) If you want to increase the capacitance by changing the shape and size of the capacitor, how would you do that?

B) If you want to increase the capacitance but NOT change the shape and size how could you do it? Explain in some detail why your idea will increase the capacitance.

C) You connect a 4 microfarad capacitor to a 10 volts battery. You then disconnect this capacitor from the battery. You then connect this 4 microfarad capacitor to an uncharged second capacitor. When you measure the voltage across the 4 microfarad capacitor it has dropped to 7.7 Volts. What’s the capacitance of the second capacitor?

Under the loanable funds theory, the equilibrium interest rate is determined by the interaction between the demand for and the supply of funds from financial market participants, mainly the household sector, the business sector and the government sector.

Holding other factors constant, predict the change in domestic interest rates that would occur when facing each of the following situations. Explain your predictions in detail.
i The total wealth of local financial market participants increases.
ii The default risk of loans decreases.
iii Domestic economic growth is thriving.
iv Economic conditions in foreign countries improve.

Data Analysis Skills and Thinking

Submit a paper of at least four pages in length, excluding the title and reference pages, that includes at least three sources, including a minimum of two scholarly sources and the text. Explain in detail why data analysis skills are so important to Spend Analysis. Describe how a structured process such as Six Sigma methodology (Chapter 4) can be useful to identify spending patterns and identify opportunities for improvement. Recommend which functional areas of the business, such as finance, should be involved in Spend Analysis efforts and justify the rationale for your choices.
