Alvin Alexander worked as a consultant for over twenty years. He began at the bottom, working for a small salary plus the exciting promise of "performance incentives." Sadly, those incentives didn't come right away. In fact, they barely came at all during the first year. But he kept pushing on, and after working 90-hour weeks for 18-24 months, and making pretty much every mistake a consultant can make -- such as offering advice without knowing all the facts, or before anyone actually asked for his advice -- things got better. The short story is that he created his own consulting firm, grew his income to over $300,000 per year, sold his business, and "retired" before his 45th birthday. Here's how Mr. Alexander describes A Survival Guide for New Consultants: As I wrote this book, I kept thinking back to my first years as a consultant -- the lean years -- and asked, "Would this information have helped me?" I also thought about the employees I hired, and how I coached them to prepare for meetings and handle certain situations. If I thought a story told an important lesson, I included it here. In the end, this book is for any consultant with ambition. It's written for the consultant who wants to be involved in the big decisions, the consultant who meets with clients and prospects to discuss their most challenging problems, the consultant who makes the big presentations, influences decision-makers, and has happy, long-term customers. It's for the person who aspires to be a partner in a consulting firm, or who wants to run his own consulting business. Finally, with the summary sections ("cheat sheets") at the end of the book, you can also use this as a reference manual, such as reminding yourself of the important points the night before a big meeting. I hope you enjoy this book, and I hope it leads to a rewarding, fulfilling career. All the best, Al (Note: This book was originally published as a Kindle eBook under the name, "Zen & the Art of Consulting.")
Save time and trouble when using Scala to build object-oriented, functional, and concurrent applications. With more than 250 ready-to-use recipes and 700 code examples, this comprehensive cookbook covers the most common problems you’ll encounter when using the Scala language, libraries, and tools. It’s ideal not only for experienced Scala developers, but also for programmers learning to use this JVM language. Author Alvin Alexander (creator of DevDaily.com) provides solutions based on his experience using Scala for highly scalable, component-based applications that support concurrency and distribution. Packed with real-world scenarios, this book provides recipes for: Strings, numeric types, and control structures Classes, methods, objects, traits, and packaging Functional programming in a variety of situations Collections covering Scala's wealth of classes and methods Concurrency, using the Akka Actors library Using the Scala REPL and the Simple Build Tool (SBT) Web services on both the client and server sides Interacting with SQL and NoSQL databases Best practices in Scala development
Alvin Alexander founded a computer consulting business in the basement of his home in the 1990s, grew it into a very successful twenty-person business, and then sold it ten years later. During the process of trying to sell his small business, he wrote many small notes before and after meetings, and those notes eventually became a diary of everything he went through. After the sale was completed, he published a portion of that diary on his website, HowISoldMyBusiness.com. The website quickly grew popular, with many comments like, “Thank you!”, “You helped me make money”, and “Please share more information.” After all that encouragement the book is finally here, including (a) an all-new “Lessons Learned” chapter, and (b) additional chapters on the five years that have passed since he sold his company.If you're thinking, “Should I sell my small business?”, or “How can I sell my company?”, this book is for you. It shares the “behind the scenes” secrets of the process of selling a business that you won't find anywhere else. Because of everything that happened during the sales process, the book will probably also be very helpful for people interested in buying a business, and people who are partners in a business, such as LLC business partners.In the end, this book is an investment. Think of it this way: How much money would you be willing to spend to make thousands of additional dollars when you sell your business? If just one tip from this book makes you just a thousand dollars, it will still be one of the best investments you ever made.
Through stories (including their own), interviews, and analysis of the most recent data available, Dr. Alvin Poussaint and journalist Amy Alexander offer a groundbreaking look at 'posttraumatic slavery syndrome,' the unique physical and emotional perils for black people that are the legacy of slavery and persistent racism. They examine the historical, cultural, and social factors that make many blacks reluctant to seek health care, and cite ways that everyone from the layperson to the health care provider can help.
In Replacement Parts, internationally recognized bioethicist Arthur L. Caplan and coeditors James J. McCartney and Daniel P. Reid assemble seminal writings from medicine, philosophy, economics, and religion that address the ethical challenges raised by organ transplantation. Caplan's new lead essay explains the shortfalls of present policies. From there, book sections take an interdisciplinary approach to fundamental issues like the determination of death and the dead donor rule; the divisive case of using anencephalic infants as organ donors; the sale of cadaveric or live organs; possible strategies for increasing the number of available organs, including market solutions and the idea of presumed consent; and questions surrounding transplant tourism and "gaming the system" by using the media to gain access to organs. Timely and balanced, Replacement Parts is a first-of-its-kind collection aimed at surgeons, physicians, nurses, and other professionals involved in this essential lifesaving activity that is often fraught with ethical controversy.
