unit 7:1 DB Food

Food and beverage managers use various purchasing methods to control inventory, reduce waste, and build vendor relations. The way materials are processed through the operation, including receiving and storage is vitally important not only to the efficient and profitable operation of the eatery, but also for quality control and health reasons.

Topic 1: Receiving and Storage

Proper purchasing, receiving, and storage of food and beverage items is critical to a food and beverage department’s or eateries’ success. In this Discussion, you will apply what you learned in the Learning Activity and Reading to the following scenario and then respond to the questions.

Scenario: Your hotel restaurant is planning a big Thanksgiving dinner for 400 guests that includes many different types of pie all requiring whipped cream. As the Food and Beverage Manager, you inform your vendor 30 days in advance of the event that you will need 10 gallons of cream. Your vendor misunderstands and has 20 gallons in ten 2-gallon containers, delivered 5 days later to a new receiving clerk who stores nine (9) of the 2-gallon containers the cream immediately. The cook sees 1 of the 2-gallon containers on a preparation table about an hour later and proceeds to use a gallon of the cream in his gravy for that night’s meal. He leaves the remainder on the preparation table shouting to his sous chef’s assistant to put the cream away when he can. Two hours later, the assistant stores the remainder in the refrigerator. Note: The cream has an expiration date three and a half weeks from the sending date.

• What were the problems in this scenario?
• Who should be responsible to remedy this situation and how should they resolve this problem while still obtaining the required amount of cream?
• What changes should be instituted going forward?

unit 6 DB food

The purchasing function is responsible for identifying the operational needs of the organization, negotiating, determining product specifications, and working with and choosing vendors. Managers are charged with making the appropriate buying decisions in an ethical and professional manner.

Topic: Purchasing and Technology

You read about blockchain ledger technology. Now do some additional research out on the Internet and share your URL with the rest of the class regarding either videos or viable information regarding blockchain technology.

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

Part A: Technology

• Discuss how you think this technology will change food and beverage purchasing. Explain your response.
• Discuss how POS systems are used in eating establishments. When does it make sense to use a POS system? What advantages are there for management in using a POS system?

Career Management: Interviewing; You will be a recruiter for a large chain of national department stores, looking to fill manager trainee positions. Then flip the switch and you will be a candidate for the jobs. The company is specifically looking for candidates who demonstrate these three qualities: initiative, dependability, and willingness to assume responsibility.

● As the recruiter(s), discuss how you would assess the applicant in each of the three desired qualities? What questions would you ask or what would you use as an indicator to determine whether the candidate possesses the quality?
● As the applicant(s), discuss what you would say to convince the recruiters that you possess each of these qualities (You have yo think outside the box).

Assume in a simple example that a change occurs in an economy that produces “Good X” and that there is a decrease in the number of sellers/producers in the economy who make “Good X”. Assume that this is a competitive market, what will happen to the equilibrium price and quantity of “Good X”? Use supply and demand analysis to demonstrate your answer and be sure to provide the rationale behind what is happening and also discuss any interesting observations or outcomes. Finally, please give an example from the news of a current event in real life that relates to the economic change affecting “Good X” above and be sure to explain why it relates.

(Note: The magnitude of any supply and/or demand shifts in this example are not specified; you may want to consider the magnitude of any shifts in your analysis).

Please analyze why “Machiavellian Thinking/Machiavellian Tactics” could be potentially damaging for modern leadership approaches. Please explain your answer.

For the fiscal year ended December 31, 2019, Nicholas Corporation reported net income of $600,000 and had 900,000 common shares outstanding from the beginning to the end of the year. On May 1, 2019, Nicholas issued 5% convertible bonds. Each $1,000 bond is convertible into 120 common shares. The total proceeds were $1,000,000 at par and were recognized in the liability and equity components using the residual value method, measuring the liability component first, at the present value of the bonds, all discounted at 8%, (the interest rate that applies to similar straight bonds). At the time of issuance, the present value of the bond was $922,685. Calculate Nicholas Corporation’s basic and diluted Earnings per share, assuming the corporation experiences a 30% tax rate. Round your answer to two decimal places.

QUESTION 5 Explain how either accounting or financial planning can be considered a ‘profession’.

Apart from direct quotes, all answers should be in your own words.

6.23 LAB: Python insert/update sqlite3 datafiles

Given is a Python program that connects to a sqlite database and has one table called writers with two columnns:

• name - the name of a writer
• num - the number of works the writer has written

The writers table originally has the following data:

name, num
Jane Austen,6
Charles Dickens,20
Ernest Hemingway,9
Jack Kerouac,22
F. Scott Fitzgerald,8
Mary Shelley,7
Charlotte Bronte,5
Mark Twain,11
Agatha Christie,73
Ian Flemming,14
J.K. Rowling,14
Stephen King,54
Oscar Wilde,1

Update the Python program to ask the user if they want to update entries or add new entries. If the name entered already exists in the writers table then the database record is updated, overwriting the original contents. If the name does not exist in the writers table, then add a new record with the writer's name and number of works. The following TODO sections must be completed.

• Check if a writer exists in the writers table
• If the writer exists in the table, locate an entry to be updated by writer's name and update the writer's value for num
• If the writer does not exist in the table, add a new entry in the writers table and provide the value for name and num

Ex: If the input is:

y
J.K. Rowling
30
y
Elton John
y
62
n

The output is:

(ID, Name, Num)
(1, 'Jane Austen', 6)
(2, 'Charles Dickens', 20)
(3, 'Ernest Hemingway', 9)
(4, 'Jack Kerouac', 22)
(5, 'F. Scott Fitzgerald', 8)
(6, 'Mary Shelley', 7)
(7, 'Charlotte Bronte', 5)
(8, 'Mark Twain', 11)
(9, 'Agatha Christie', 73)
(10, 'Ian Flemming', 14)
(11, 'J.K. Rowling', 30)
(12, 'Stephen King', 54)
(13, 'Oscar Wilde', 1)
(14, 'Elton John', 62)

Delivering negative news involves a buffer or cushion statement, an explanation, the negative news itself, and a redirecting statement. Whether you choose a direct or an indirect approach, the message should be delivered clearly and concisely, with respect for the receiver and the organization.

Q1. (Please answer) When should you use an indirect approach in delivering a negative news message? Explain your answer clearly.

Q3. Consider the following scenarios and complete the short exercise associated with them...

(a)Sales have decreased for two consecutive quarters at your business. You have been instructed by senior leaders to inform your sales team that their hours, and base pay, will be reduced by 20 percent. While you may have a few members of your sales team that are underperforming, you want to retain the entire team. Write a negative news message (in appropriate memo format to your sales team) in a direct or indirect approach informing your sales team of the news.

(b)You have observed and documented an employee being late and taking long breaks for the past two weeks. This employee has been a good employee for many years but seems to have issues recently... Following best practices from the theory, write out a summary of the conversation you need to have with the employee. (You may answer by role-playing the components of your “plan”).

The Sarbanes-Oxley Act of 2002 is a federal government response to corporate ethics problem. In your opinion, and using support (citations) from your readings, does this Act do enough to help solve ethical dilemma among public corporations in the US? If not, what other actions would be appropriate?

Implement a Lucky Draw game in which the user has to input an integer ‘input’ and multiply it with a random integer to get the product ‘p’. Depending upon the value of ‘p’ display the prize amount. Use a suitable Java Collection object to store the prize amount for each value of ‘p’.

Design a generic stack data structure (not a Collection object) which can handle integer, double, character and any user-defined objects. Write a menu-driven Java program to test it.
