...contains a whopping 140 terabytes of information. A successor, the Large Synoptic Survey Telescope, due to come on stream in Chile in 2016, will acquire that quantity of data every five days. Such astronomical amounts of information can be found closer to Earth too. Wal-Mart, a retail giant, handles more than 1m customer transactions every hour, feeding databases estimated at more than 2.5 petabytes—the equivalent of 167 times the books in America’s Library of Congress. Facebook, a social-networking website, is home to 40 billion photos. And decoding the human genome involves analysing 3 billion base pairs—which took ten years the first time it was done, in 2003, but can now be achieved in one week. All these examples tell the same story: that the world contains an unimaginably vast amount of digital information which is getting ever vaster ever more rapidly. This makes it possible to do many things that previously could not be done: spot business trends, prevent diseases, combat crime and so on. Managed well, the data can be used to unlock new sources of economic value, provide fresh insights into science and hold governments to account.

...226 IEEE/ACM TRANSACTIONS ON NETWORKING, VOL. 9, NO. 3, JUNE 2001 Network Support for IP Traceback Stefan Savage, David Wetherall, Member, IEEE, Anna Karlin, and Tom Anderson Abstract--This paper describes a technique for tracing anonymous packet flooding attacks in the Internet back toward their source. This work is motivated by the increased frequency and sophistication of denial-of-service attacks and by the difficulty in tracing packets with incorrect, or "spoofed," source addresses. In this paper, we describe a general purpose traceback mechanism based on probabilistic packet marking in the network. Our approach allows a victim to identify the network path(s) traversed by attack traffic without requiring interactive operational support from Internet Service Providers (ISPs). Moreover, this traceback can be performed "post mortem"--after an attack has completed. We present an implementation of this technology that is incrementally deployable, (mostly) backward compatible, and can be efficiently implemented using conventional technology. Index Terms--Computer network management, computer network security, network servers, stochastic approximation, wide-area networks. I. INTRODUCTION D ENIAL-OF-SERVICE attacks consume the resources of a remote host or network, thereby denying or degrading service to legitimate users. Such attacks are among the hardest security problems to address because they are simple to implement, difficult to prevent, and very difficult...

...PRAISE FOR THE EXTRAORDINARY LEADER “The Zenger Folkman leadership model is distinguished from others in that it is backed up by research and data. That data validates the effectiveness of identifying an individual’s strengths and developing them, rather than focusing on weaknesses. The Zenger Folkman philosophy has its eye on the right goal – real, measurable results.” —Bill Blase Senior Executive Vice President Human Resources AT&T Corp. “I fell in love with The Extraordinary Leader on page 1. From the moment I started reading I really got jazzed, and my enthusiasm only increased the more I read. You see, I’m just mad about books that attack cherished but unsupportable assumptions about anything, especially leadership. That’s exactly what Jack Zenger and Joe Folkman do, and they do it persuasively, precisely, and professionally. The Extraordinary Leader is no hackneyed rehashing of tired nostrums. Through their exceptional research, the authors demonstrate and prove that leadership does make a difference and that you can learn to lead. There are some profound insights in this book, and whether you’ve studied leadership for over 20 years, as I have, or you are brand new to the subject, Zenger and Folkman give you much more than your money’s worth. And while their research gives the book distinctive credibility, their examples and practical applications give it life. This is a book that scholars and practitioners will be referring to for years to come. If your goal is to...

The meeting was only 10 weeks away and Bernstein, Trexel’s president and chief executive officer, needed to present a coherent vision of the company’s new strategy. Bernstein believed that Trexel’s patented technology for manufacturing foamed plastics had the potential to revolutionize much of the worldwide plastics industry. His innovative process technology, known as MuCell, allowed the Woburn, Massachusetts company to produce foamed plastic utilizing 25% to 50% less material than traditional solid plastics without a significant decrease in the strength of the plastic. Bernstein believed the market for products produced via this...

...McKinsey Global Institute June 2011 Big data: The next frontier for innovation, competition, and productivity The McKinsey Global Institute The McKinsey Global Institute (MGI), established in 1990, is McKinsey & Company’s business and economics research arm. MGI’s mission is to help leaders in the commercial, public, and social sectors develop a deeper understanding of the evolution of the global economy and to provide a fact base that contributes to decision making on critical management and policy issues. MGI research combines two disciplines: economics and management. Economists often have limited access to the practical problems facing senior managers, while senior managers often lack the time and incentive to look beyond their own industry to the larger issues of the global economy. By integrating these perspectives, MGI is able to gain insights into the microeconomic underpinnings of the long-term macroeconomic trends affecting business strategy and policy making. For nearly two decades, MGI has utilized this “micro-to-macro” approach in research covering more than 20 countries and 30 industry sectors. MGI’s current research agenda focuses on three broad areas: productivity, competitiveness, and growth; the evolution of global financial markets; and the economic impact of technology. Recent research has examined a program of reform to bolster growth and renewal in Europe and the United States through accelerated productivity growth; Africa’s economic potential;...

...Organizational Behavior - MGT502 VU MGT - 502 ORGANIZATIONAL BEHAVIOR Lesson 1 OVERVIEW OF COURSE This subject/course is designed to teach the basic language of organizational behavior to diverse audience/students, including those who are studying this as a supporting subject for their bachelor degree program. This course is designed to provide you the foundations of organizational behavior whether you intend to work in any field of interest. Organizational behavior offers both challenges and opportunities for managers. It recognizes differences and helps managers to see the value of workforce diversity and practices that may need to be changed when managing in different countries. It can help improve quality and employee productivity by showing managers how to empower their people as well as how to design and implement change programs. It offers specific insights to improve a manager’s people skills. In times of rapid and ongoing change, faced by most managers today, OB can help managers cope in a world of “temporariness” and learn ways to stimulate innovation. Finally, OB can offer managers guidance in creating an ethically healthy work climate. Managers need to develop their interpersonal or people skills if they are going to be effective in their jobs. Organizational behavior (OB) is a field of study that investigates the impact that individuals, groups, and structure have on behavior within an organization, and then applies that knowledge to make organizations work...
