Choose any country except the United States, and your native country (if different from the United States). Describe the culture of this country in detail. What are some key cultural aspects of which a U.S. expatriate on assignment in this country should be aware? What aspects of this country’s culture could cause culture shock for a U.S. expatriate? What advice would you give to someone who was preparing for a long-term assignment in this culture? Finally, would you want to spend an extended amount of time as an expatriate in this country? Why or why not? Support your assessment.

Murray, the longtime lab director in the R&D (research and development) department, has announced his retirement. Marianne, the head of R&D for three years, has received great advice from Murray on every topic she has asked him about. Murray is a modest man, but she suspects that he knows more about their department than the rest of the group put together. They meet in his office to talk about ways Murray can document his knowledge so that it doesn’t “walk out the door” with him when he retires. Murray shows Marianne dozens of binders and several file cabinet field with one of a kind documents that predate the use of personal computer and electronic file. He suggests that he spend the rest of his time labeling everything and putting together a list of what he has. Marianne has a different idea. She appreciates Murray’s interest in preserving the past, but she believes it is essential to capture his perspective on the new technologies,

new products, and new processes that have been implemented over the years. She wants to put together an ad hoc committee to work with Murray. she asks him to meet with her in two days to talk about the committee and what can be accomplished before Murray retires.

1. Why does Marianne want to preserve Murray’s perspective on the changes he has been part of?

2. How can Murray and the committee accomplish Marianne’s goals?

Read each of the statements below. Write down or discuss with others why these statements might be offensive. Do they reinforce a stereotype, treat people in non-parallel ways (indicating that one type of person has more power/privilege or prestige than another), or assume that certain groups must behave in certain ways? In some cases, the words equate a person or group of people to a trait. Rewrite each statement so that it treats people in parallel ways, does not reinforce stereotypes, and does not equate groups of people to a trait.

This company uses a perpetual inventory system. It had the following beginning inventory and current year purchases of its product.

Jan 1. Beginning Inventory ..... 50 units @ $100 = $5,000

Jan 14. Purchase .......................150 units @ $120 = 18,000

Apr 30. Purchase........................ 200 units @ $150= 30,000

Sept 26th. Purchase................... 300 units @ $200= 60,000

The company transacted sales on the following dates at $350 per unit sales price.

Jan 10. 30 units (specific cost: 30 @ $100)

Feb 15. 100 units (specific cost: 100 @ $120)

Oct 5. 350 units (specific cost: 100 @ $150 and 250 @ $200)

USING (THE WEIGHTED AVERAGE COSTING METHOD) ANSWER THE FOLLOWING QUESTIONS:

A. Identify and compute the costs to assign to the units sold. (Round per unit costs to three decimals.)

B. Identify and compute the costs to assign to the units in ending inventory. (Round inventory balances toe the dollar)

C. How likely is it that the Weighted Average method will reflect the actual physical flow of goods? How relevant is that factor in determining wether this is an acceptable method to use?

D. What is the impact of this method versus others in determining net income and income taxes?

E. How closely does the ending inventory amount reflect replacement cost?

Calculate the molarity of a solution prepared by dissolving 12.3g of Na2CrO4 in enough water to produce a solution with a volume of 900.mL . Express the molarity to three significant digits.

****JAVA Program****

Make a LandTract class with the following fields:

• length - an int containing the tract's length
• width - an int containing the tract's width

The class should also have the following methods :

• area - returns an int representing the tract's area
• equals - takes another LandTract object as a parameter and returns a boolean saying
whether or not the two tracts have the same dimensions (This applies regardless of whether the dimensions match up. i.e., if the length of the first is the same as the width of the other and vice versa, that counts as having equal dimensions.)
• toString - returns a String with details about the LandTract object in the format:
LandTract object with length 30 and width 40
(If, for example, the LandTract object had a length of 30 and a width of 40.)

Write a separate program that asks the user to enter the dimensions for the two tracts of
land (in the order length of the first, width of the first, length of the second, width of the second). The program should print the output of two tracts' toString methods followed by a sentence stating whether or not the tracts have equal dimensions. (If the tracts have the same dimensions, print, "The two tracts have the same size." Otherwise, print, "The two tracts do not have the same size.") Print all three statements on separate lines.
