...In some ways I’d say it is good to feel pain or else your life is not real, to live life without pain and hardships, makes you lazy and ordinary. No man has ever become great by sleeping all day long. To attain success pain must become a secondary objective and the goal to be achieved primary. Focus is most important, and that is when it does not matter whether you slept 2 hours or 8, or whether you ran 8km or 100m but what is important is whether you have achieved what you set out to do. Having said this we must not set our goals low, in order to gain satisfaction at having achieved it. Our goals must be reasonably high, if you aim for the stars you might at least land on the moon. Richard Branson never imagined that being dyslexic and dropping out of school at a young age would prevent him from reaching where he wanted to. He set his heights on what others would have seen as impossible, but it is this high level of self belief that got him to where he is now. When Ferdinand Piëch laid down 10 parameters in order to manufacture the VW Phaeton, half his engineers walked out believing those parameters were beyond possible. But today we see the Phaeton will all those parameters included, and still making it cheaper than the Mercedes S500. To aim high and dream big is nothing wrong as long as you do not keep dreaming. Motivation, hard work, perspiration are all tools to achieve the impossible. Success comes with 1% inspiration and 99% perspiration. To be inspired is not enough...

...Employee Absenteeism Kmart Corporation Alvin Williams Professor Whatley LG415 Quality Control Park University INTRODUCTION The purpose of this research paper is to identify employee absenteeism and explain the process of how Kmart was able to successfully merge with Sears effectively without completely diminishing employee morale and loyalty. Let us first begin by going into detail to primarily explain what employee absenteeism is. In the workforce it is described as a failure to appear for work in a routine period of time. It also means the number of occurrences of missed work without valid reasoning. Picture the scenario that you are shopping in Kmart and you have finally completed your shopping to proceed to check out. The time just so happens to be three o’clock, which are the shift change hours for cashiers. There are three customers ahead of you and only two lanes open. You notice that there is a delay in check out times. You finally get to the counter to pay and over hear the cashier complaining that she will have to stay another two hours because her replacement has called out sick once again, without proper notice. At this point the cashier becomes a little irritated in her responses and appears to be in no way interested in pleasing the customer. What happened to the employee that was smiling just three customers before you? I can easily explain. The motivation the...

...reserved. No part of this publication may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, electronic, mechanical, recording or otherwise, without the prior written permission of Charles E. Cook. Manufactured in the United States of America. Preface You will find this book to be somewhat unusual. Most computer science texts will begin with a section on the history of computers and then with a flurry of definitions that are just “so many words” to the average student. My approach with Blue Pelican Java is to first give the student some experience upon which to hang the definitions that come later, and consequently, make them more meaningful. This book does have a history section in Appendix S and plenty of definitions later when the student is ready for them. If you will look at Lesson 1, you will see that we go right to work and write a program the very first day. The student will not understand several things about that first program, yet he can immediately make the computer do something useful. This work ethic is typical of the remainder of the book. Rest assured that full understanding comes in time. Abraham Lincoln himself subscribed to this philosophy when he said, “Stop petting the mule, and load the wagon.” The usual practice in most Java textbooks of introducing classes and objects alongside the fundamental concepts of primitive variable types, loops, decision structures, etc. is deferred until the student has...

Thus, the Client is strongly coupled with the Vendor class. Later, it is decided to change vendors. Vendor2 is selected which has different method names. Example (cont’d) The Client must be modified in order to adapt to the new vendor. What was the problem? The Client class encapsulates some portion of application logic, which is intertwined with the Vendor class. This causes the strong coupling/ dependence. Thus, modifying the Client code to adapt to the new vendor could result in errors being injected into the application logic. How do we mitigate this situation where we have a Client coded against a Vendor, where the Vendor will change? Two helpful design principles • Identify the aspects of your application that vary and separate them from what stays the same. • Program to an interface, not an implementation. • The first principle suggests that we separate the application logic from...
