The HR department is charged with creating, implementing, and enforcing fair labor laws and policies. Laws that impact foodservice systems include compensation and wages, hours and schedules of work, security and employment, and employment benefits and services.

Human Resources screens candidates through an automated system and/or in person and usually pass along the final candidates to the prospective managers to whom the position will report. Therefore, it is critical that food and beverage service managers understand the legalities to be considered when conducting an interview with a potential hire.

Topic 1: Hiring for the Position

Scenario (fictitious): A five star Chinese restaurant in Manhattan previously only open for dinner, has experienced considerable growth in the last six months and they have decided to expand their operation by opening for lunch Monday through Friday from 11:00 am to 2:00pm. This will increase production in the kitchen which makes it necessary to add to the staff.

The recruiter has selected the final two candidates to become sous chef. Now you as Chef must conduct the final interviews. Do some research out on the Internet and respond to the questions.

• What questions might you ask?
• What questions would not be legal?
• What specific questions might delineate between a good candidate and the perfect candidate?

The following information in a through h applies to the company at the end of the current year.

a. The bank reconciliation as of December 31, 2017, includes the following facts.

Reported on the bank statement is a canceled check that the company failed to record. (Information from the bank reconciliation allows you to determine the amount of this check, which is a payment on an account payable.)

b. An examination of customers’ accounts shows that accounts totaling $679 should be written off as uncollectible. Using an aging of receivables, the company determines that the ending balance of the Allowance for Doubtful Accounts should be $700.

c. A truck is purchased and placed in service on January 1, 2017. Its cost is being depreciated with the straight-line method using the following facts and estimates.

d. Two items of equipment (a sprayer and an injector) were purchased and put into service in early January 2015. They are being depreciated with the straight-line method using these facts and estimates.

e. On August 1, 2017, the company is paid $3,840 cash in advance to provide monthly service for an apartment complex for one year. The company began providing the services in August. When the cash was received, the full amount was credited to the Extermination Services Revenue account.

f. The company offers a warranty for the services it sells. The expected cost of providing warranty service is 2.5% of the extermination services revenue of $57,760 for 2017. No warranty expense has been recorded for 2017. All costs of servicing warranties in 2017 were properly debited to the Estimated Warranty Liability account.

g. The $15,000 long-term note is an 8%, five-year, interest-bearing note with interest payable annually on December 31. The note was signed with First National Bank on December 31, 2017.

h. The ending inventory of merchandise is counted and determined to have a cost of $11,700. Bug-Off uses a perpetual inventory system.

Required:
1. Determine amounts for the following items:  

1. Correct (reconciled) ending balance of Cash, and the omitted check amount.
2. Adjustment needed to obtain the correct ending balance of the Allowance for Doubtful Accounts.
3. Depreciation expense for the truck used during year 2017.
4. Depreciation expense for the two items of equipment used during year 2017.
5. The adjusted 2017 ending balances of the Extermination Services Revenue and Unearned Services Revenue accounts.
6. The adjusted 2017 ending balances of the accounts for Warranty Expense and Estimated Warranty Liability.
7. The adjusted 2017 ending balances of the accounts for Interest Expense and Interest Payable.

2. Use the results of part 1 to complete the six-column table by first entering the appropriate adjustments for items a through g and then completing the adjusted trial balance columns. (Hint: Item b requires two adjustments.)
3. Prepare journal entries to record the adjustments entered on the six-column table. Assume Bug-Off’s adjusted balance for Merchandise Inventory matches the year-end physical count.
4a. Prepare a single-step income statement for year 2017.
4b. Prepare a statement of owner’s equity (cash withdrawals during 2017 were $10,000) for year 2017 and there were no investments by the owner in the current year.
4c. Prepare a classified balance sheet as at 2017.

Effective money management begins with a comparison of the actual money spent versus what is in the budget. The budget process is a series of steps if followed, will produce an equitable distribution of the company’s revenue and expenses. A foodservice budget has factors that should be considered such as food costs, salaries, equipment, maintenance, utility services and taxes. The budget should be completed in advance of the first fiscal billing cycle.

Topic: Applying Budgetary Considerations and Leadership

Make sure to title each response as Part A or Part B.

Part A: The Food Truck

You are the owner of several food trucks in the nearest city to you. You serve gourmet desserts, pastries, and coffee around the city. Explain the following:

Optimal order quantity _____ pounds

b. How many orders will AMA place during the next year? Round intermediate calculations to 2 decimal places (e.g., $18.61) and your answer to 2 decimal places (e.g., 108.37 times).

Number of orders ______

c. How frequently should the company order cotton? This is sometimes called the time between orders (TBO). Round intermediate calculations to 2 decimal places (e.g., $18.61) and your answer to 2 decimal places (e.g., once every 4.13 months).

Company orders once every ______months

d. Assuming that the first order is needed on April 1, when should AMA place the order?

a. March 15th

b. April 1st

c. April 15th

Annual holding cost________per year

f. What is the resulting annual ordering cost when the optimal quantity (part a) is ordered? Round intermediate calculations to 2 decimal places (e.g., $18.61) and your answer to the nearest whole number.

Annual ordering cost ______

g. If the annual holding cost percentage was only 5 percent, how would it affect the annual number of orders, the optimal order size, and the average inventory?

Short answer question:

Mr. Jones needs to send a shipment from China to the United States. His boss asks him to prepare a set of potential crash options for accomplishing this in 5 days, 4 days, 3 days, 2 days, and 1 day. He calls an air transport company and finds out that the shipment can be flown in one day for a cost of $1000. Then he calls an ocean shipping company and finds out that it can be transported in 5 days for a cost of $200. He uses these two numbers to find the slope: it costs $800 more to reach the US 4 days earlier, or $200 per day. Then, he uses the slope to calculate the cost of a 4-day trip ($400), a 3- day trip ($600), and a 2-day trip ($800). What is wrong with Mr. Jones’s approach?

At what substrate concentration would an enzyme with Km of 5mM operate at one-quarter its maximum rate? Give your answer in units of mM to 1 decimal place.

I'm currently interested in 1-dimensional (linear) Sigma Models.

In the theory of 2-Dimensional GLSM, the fields can be viewed as an embedding of the worldsheet in some target Manifold of higher dimension.

Is there a similar, geometrical, interpretation of the 1-dimensional case?

So far i could only find references to superconformal quantum mechanics, where the N-dimensional target space is taken to be N particles. I'm however interested in geometrical insight

See for example Witten's famous "Phases of N=2 Theories in 2 Dimensions", is there an equivalent in 1-Dimension?
