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.

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.

Carla McFarland was an associate professor of English literature at Highland College. She was the only single person in her department. Consequently, she was frequently assigned classes late in the evening, on weekends, and during the summer semester. She was also called upon to pick up visiting professors and serve as their escort and guide during their stays at the college. She received extra duty as adviser to the The Highland Review, the college's literary magazine. When McFarland complained about the unequal treatment, she was told that the married professors had family responsibilities that she did not have, which took up much of their time and prevented them from having the flexibility that she had. Thus, she would continue to carry the extra load. McFarland filed a complaint with the EEOC.
Can discrimination based on an employee's status as a single person be considered unlawful under the Civil Rights Act? Explain. Is this a case of disparate impact or disparate treatment? Explain. Final answer must be 3 sentences minimum.

Toyota vehicle recalls At the end of 2009, Toyota Motor Corporation faced three separate related recalls of automobiles. The first recall, on November 2, 2009, was to correct a possible incursion of an incorrect or out-of-place front driver's side floor mat into the foot pedal well. which can cause pedal entrapment. The second recall, on January 21, 2010, begun after some crashes were shown not to have heen caused by floor mat incursion. This latter defect was identified as a possible mechanical sticking of the accelerator pedal causing unintended acceleration, referred to as Sticking Accelerator Pedal by Toyota. As uf January 28, 2010, Toyota had announced recalls of approximately 5.2 million vehieles for the pedal entrapment/ floor mat problem, and an additional 23 million vehicles for the accelerator pedal problem. Approximately 1.7 million vehicles were subject to both. Thus, investigations on such issues started immediately. On February 8, 2011, findings into the investigation were released After a 10-month search, scientists found no clectronic defect in Toyota vehicles. Driver error or pedal misapplication was found responsible for most of the incidents. The report ended stating. "Our conclusion is Tayota's problems were mechanical, not electrical." This included sticking accelerator pedals. and pedals cought under floor mats. In fact, in 2005. Toyota launched the "Customer First" program, to bring the voice of customers in an attempt to improve the quality of its vehicles. But it was quietly discontinued in early 20X19. A Toyota manager justified its elimination by announcing "We had come to believe that quality was maintained mainly in processes and not in products, and no quality at source was applied," Moreover, when implemented coerectly, any impeovement in quality processes can reduce waste and thus lead to reduced cost and improved profitubility. Therefore, Toystu wanted to know that if paying more in increasing the quality of their vehicles, would pay them the benefits they are aiming for, or it would be just another lost investment. but On October 24, 2013, a jury ruled against Toyotu and found that unintended acceleration could have been caused due to deficiencies in the drive-by-wire throttle system or Electronic Throttle Control System (ETCS). 1) What two functional perspective on quality did Toyotan upply? Justify. 2) According to Juran's trilogy quality theory, in which step of the three was the problem? Justify. 3) Which sphere of the three spheres of quality was Toyota facing problem in? Justify? 4) Which point of 14 points of Deming's quality thenry was presented in the above case? Justify.

McBurger, Inc., wants to redesign its kitchens to improve productivity and quality. Three designs, called designs K1, K2, and K3, are under consideration. No matter which design is used, daily production of sandwiches at a typical McBurger restaurant is for
500
sandwiches. A sandwich costs
$1.30
to produce. Non-defective sandwiches sell, on the average, for
$2.50
per sandwich. Defective sandwiches cannot be sold and are scrapped.
The goal is to choose a design that maximizes the expected profit at a typical restaurant over a 300-day period. Designs K1, K2, and K3 cost
$100,000,
$130,000,
and
$180,000,
respectively.
Under design K1, there is a .80 chance that 90 out of each 100 sandwiches are non-defective and a .20 chance that 70 out of each 100 sandwiches are non-defective. Under design K2, there is a .85 chance that 90 out of each 100 sandwiches are non-defective and a .15 chance that 75 out of each 100 sandwiches are non-defective. Under design K3, there is a .90 chance that 95 out of each 100 sandwiches are non-defective and a .10 chance that 80 out of each 100 sandwiches are non-defective.
The expected profit level of design K1 is
$nothing.
(Enter
