Next Day Air Service Case Study

...Pre-course Assignment – NDAS Case Study Question 1 The current level of office automation at NDAS varies with each department. The company is also in the process of upgrading its computer systems to improve performance and reduce costs. The Payroll Department has a minicomputer on which it runs the payroll twice monthly. The Sales and Marketing department has a desktop computer for each account representative. All the computers are connected to a LAN, which serves only the Sales and Marketing department. The Accounts Receivable Division has recently replaced its old minicomputer with a more powerful microcomputer. This new server supports databases for both customer billing and bad debts. The Accounts Payable Division maintains its vendor database on an older minicomputer. It is in the process of downsizing to a powerful desktop server. The vendor database contains billing information of NDAS and ODI. The Accounts Payable Division is also responsible for payroll. Employees in Accounts Receivable and Payable divisions have PCs on their desks. The Fleet Maintenance Division has no computers and processes all its information manually. The Dispatch department, which is part of Fleet Maintenance, also processes its work manually. This division is responsible for bundling incoming packages and preparing them for overnight delivery. The Dispatch department is most in need of a network. The various branches and agents of NDAS are located far apart - there may be delays...

Ndas Chapter 1

...1. Briefly describe the current state of Next Day Air Service's office automation, system integration, and networking. Begin by explaining how each department uses information technology, what hardware it uses, and what functions currently are automated. Also assess which department is most in need of a network. The level of automation varies significantly among the NDAS departments and offices. In addition, NDAS is in the process of downsizing to achieve a more cost-effective computer support system. For example, the Sales and Marketing Division has a desktop computer for each of the account representatives. All of these computers are connected to a small local area network (LAN) that serves only the Sales and Marketing Division. The Accounts Receivable Division recently downsized its minicomputer to a powerful desktop computer with a faster processor, motor memory and increased disk storage space. This new desktop supports databases for both customer billing and “bad dept” expenses. The Accounts Payable Division has an older minicomputer and is in the process of downsizing to a modern powerful desktop computer. It has its own vendor database that includes invoices received by NDAS from other carries stored on the older minicomputer. Fleet Maintenance prefers to process all its information manually; however, this area is being considered for automation. None of the departmental computers is integrated. The Dispatch department needs a high speed data communication network...

Air Traffic Control Case Study

...kind of stress that air traffic controllers face on the job? Why or why not? No, I don’t think I would be able to handle the stress of being an air traffic controller. After reading the case study, I understood just how much pressure and responsibility that is put on their shoulders. According to the National Air Traffic Controllers Association (NATCA), on an average day, controllers handle 87,000 flights. That’s a couple million people’s lives in my hands on any given day and if I make any kind of small mistake, 400 people could lose their lives just like that. On the last case study I was asked if I would want to manage an IKEA store because I didn’t think I could handle watching over all of the employees, so I definitely wouldn’t be able to or want to handle millions of people’s lives. 2) In your opinion, which causes of work stress, or organizational stressors, are likely to be among the most common experienced by air traffic controllers? Explain your reasoning. I would say that Task Demands are the most common stressors experienced by air traffic controllers. I say this because they have such a highly demanding job which depends upon high levels of responsibility, quick decisions, and critical decisions. On the job, air traffic controllers have to make decisions quickly while realizing that the wrong one may endanger, or even end, the lives of hundreds and thousands of people. 3) Controller Pete Rodgers says that any gathering of air traffic controllers...

...outbreak will be presented to discuss the international pattern and movement of the disease. A discussion of how the measles outbreak could affect the community will also be presented. Next, this paper will present the appropriate protocol that a community health nurse will follow to report a SARS outbreak in the community. The last subject this paper will discuss is how a community health nurse modifies their care of clients with respiratory diseases during a time when the air quality index is poor. A. Measles Rubeola or measles is a respiratory disease. Measles is a virus that normally grows in the throat cells that line the back of the throat and lungs. Once infected, measles causes runny nose, fever, cough and a head to toe rash that occurs 14 days after exposure (CDC, 2013). A1. Outbreak In the year 2000 measles became eliminated in the United States. Elimination means the disease is no longer native to the U.S. and cases are not reported for a twelve month period in endemic proportions. Outbreaks occur when people travel to countries where the disease is still present (Gastanaduy et al., 2014). Europe, Asia, Africa, and the Pacific have countries where the disease has not been eliminated. International travel to these other countries can expose travelers bringing imported cases of measles to the United States (Gastanaduy et al., 2014). The Los Angeles County Department of Public Health (LACPDH) was notified on August 26, 2011 that a...

The case study begins here in Chapter 1 and continues throughout the rest of the book. It requires you to complete tasks that are related to topics covered in each corresponding chapter of the text. The end of each chapter contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers. As with any real-life problem with ambiguities or unresolved considerations, you must make your own assumptions. Feel free to read ahead or use the index to find related subjects that support your recommendations. Your instructor may provide additional guidelines regarding report formats, Web and library resources, key assumptions, and the like for the various questions and problems presented in this case study. Be sure to provide adequate justification for any recommendations you make. (NDAS) was founded in 1985 to compete in the expanding market for overnight package deliveries. NDAS provides local pickup and delivery of these parcels and other small freight items. The founders initially restricted their efforts to the rapidly growing central Florida region. To support...

Shipping method | Delivery time | Charge | Standard shipping | 3–7 days | $3.99 | Second-day air | 2 business days | $8.98 | Next-day air | 1 business day | $13.98 | a. What is the opportunity cost of buying online instead of at the bookstore? Note that if you buy the book online, you must wait to get it. The opportunity cost of buying online instead of at the bookstore would be whatever is you would need to give up to get the book online. This would mean that the opportunity cost of buying online would include the sum of the shipping charge and the time that you would spend waiting on the book to arrive. If you buy the book at the store, you would be able to get the book the same day but it would also mean losing out on the possible savings that you would get if you bought it online. b.

...Chapter 4 Mini Case 2 Ratios and Financial Planning at S & S Air Chris Gumede was recently hired by S&S Air to assist the company with its financial planning and to evaluate the company’s performance. Chris graduated from university five years ago with a finance degree. S&S Air was founded 10 years ago by friends Mark and Thandi. The company has manufactured and sold light aeroplanes over this period and the company’s products have received high reviews for safety and reliability. The company has a niche market in that it sells primarily to individuals who own and fly their own aeroplanes. The company has two models, the Birdie which sells for R2 530 000 and the Eagle which sells for R5 780 000. While the company manufactures aircraft, its operations are different from commercial aircraft companies. S&S Air builds aircraft to order. By using prefabricated parts, the company is able to complete the manufacture of an aeroplane in only five weeks. The company also receives a deposit on each order, as well as another partial payment before the order is complete. In contrast, a commercial aeroplane may take one and a half to two years to manufacture once the order is placed. Mark and Thandi have provided the following financial statements. Chris has gathered the industry ratios for the light aeroplane manufacturing industry. S&S Air 2008 Financial Statements |Income Statement | | ...

...viral Pneumonia that is very serious for those affected. It causes acute respiratory distress for the patient which can cause death. SARS is transmitted by contact. According to the U.S National Library of Medicine the coronavirus can live up to 6 hours on hands, tissues and some other surfaces and can stay active for up to three hours after the droplets have dried (A.D.A.M, 2013). The virus can live in feces for nearly four days and it is unknown exactly how long it can live in freezing temperatures but it is believed to live for months or maybe even years. The Coronavirus family is the same group that births the common cold, just as you can catch the cold over and over again, you can also become re-infected with SARS. Since this is a newer illness only manifesting in 2003 there are still unknowns regarding the illness. One of these things is how long before and after someone is contagious with the infection. It is clear that they are actively contagious while showing symptoms. Usually people who are infected will begin showing symptoms within a few days to two weeks after being initially exposed. This can vary depending on age, immune system compromise and other factors. Symptoms to look for are dyspnea, fever, muscle aches, headache, and a cough that begins 2-3days after the initial onset of other symptoms (A.D.A.M, 2013). If you have these symptoms you need to be seen and treated by licensed medical staff. They will begin by...
