GENERAL BUSINESS COURSE QUESTION:

Joe and Jill were talking about the role played by the Federal Reserve System in the United States. Joe seemed to be quite well informed about the functions and activities of our central bank. "You see, Jill, the Fed is the main guardian of our nation's economic stability," Joe declared. "In America, we don't want inflation and we don't want recession. To stretch the situation just a bit, we are frightened, absolutely terrified, by thoughts of hyperinflation and depression. So, the Fed maintains the right to alter the situation and protect us from these two monsters. And you ask, how they do that? The answer is the discount rate. That is the device that the Federal Reserve System uses to keep us safe."

Jill was enjoying listening to her friend explain it all. Joe continued, "Now the discount rate is the interest rate that the twelve Federal Reserve Banks around the country charge their member banks on a loan. So, when the discount rate goes up, all interest rates tend to go up. And, happy to say, when interest rates go up all over America, this tends to slow down any inflationary tendencies." Jill asked, "Does the Fed have other tools for stopping inflation?" "No," said Joe.

7) Has the economy recovered from the last recession? What factors led you to your answer? You should be able to back up your opinion. Don't use blog opinions. Make sure your source(s) is/are based upon facts.

As part of a study of wheat maturation, an agronomist selected a sample of wheat plants at random from a field plot. For each plant, the agronomist measured the moisture content from two locations: one from the central portion and one from the top portion of the wheat head. The agronomist hypothesizes that the central portion of the wheat head has more moisture than the top portion. What can the agronomist conclude with α = 0.01? The moisture content data are below.

Condition 1:

top portion

moisture content

wheat head

central portion
Condition 2:
wheat maturation

top portion

wheat head

central portion

Managers and employees have long expressed dislike and skepticism about performance appraisal, as it is typically practiced in organizations. Some HR practitioners and consultants, such as Samuel Culbert, have advocated getting rid of the standard performance appraisal programs. Culbert has suggested that the arguments typically given for performance appraisal are invalid and, in a word, “bogus.”  

a. Describe two arguments or reasons that are typically given in support of formal performance appraisals.

b. Then explain why Culbert and others who are skeptical of performance appraisal believe these arguments are weak or bogus.

c. Explain your perspective on whether performance appraisals are necessary, and why or why not. If you believe they are not necessary, explain what procedures, if any, you would recommend to fulfill the functions that performance appraisals are said to fulfill.

Question:

Create the node structure and the linked list class. The sample class has implemented the following member methods:

o constructor

o destructor

o print(),

o addLast()

2. Implement the following member methods:

▪ addFirst (T data) // Adds a node with data at the beginning of the list

▪ pop() // Removes the first node of the list. Note: Don't forget to delete/reallocate the removed dynamic memory

▪ contains(T data) // Returns true or false if a node contains the data exists in the list

▪ update(T oldDate, T newData) // Updates the oldData of a node in the list with newData.

▪ size() // Returns the number of nodes in the list

▪ remove( T data) //Removes the node that contains the data. Note, you will need to check if the node exists. Again, don't forget to delete/re-allocate the dynamic memory

3. (Extra Credit Part) Implement the following additional member methods

▪ insertAfter(int n, T data) //Adds a node after the n-th node. Note, you will need to check if the n th node exists, if not, do addLast().

▪ merge(const LinkedList &linkedlist) //Merges this object with linkedlist object. In other words, add all nodes in linkedlist to this object.
