Drawing on two decades of government efforts to "secure the homeland," experts offer crucial strategic lessons and detailed recommendations for homeland security. For Americans, the terrorist attacks of September 11, 2001, crystallized the notion of homeland security. But what does it mean to "secure the homeland" in the twenty-first century? What lessons can be drawn from the first two decades of U.S. government efforts to do so? In Beyond 9/11, leading academic experts and former senior government officials address the most salient challenges of homeland security today.

This powerful retrospective analysis of the 1999 Columbine High School shooting aftermath considers society's response to the attack, long-term implications of the shooting, and the ways in which research and related policy must continue to move forward. An indispensable resource for anyone interested in learning about the long-term impact of the 1999 Columbine High School shooting, Columbine, 20 Years Later and Beyond provides a comprehensive look at how the event unfolded, what has changed since the attack, and how this information can be used to prevent future mass shootings. Authors Jaclyn Schildkraut and Glenn Muschert, both experts on mass shootings, share their broad understanding of this tragedy and its aftermath. Columbine became the measuring stick against which all other mass shootings would be compared, and this book details with great sensitivity the ensuing changes to school security, law enforcement's response to active shooter situations, threat assessment practices, legislative efforts, and media coverage of unfolding situations. With delicacy and tact, Schildkraut and Muschert help to answer the painful question raised by a stone on the wall of the Columbine Memorial: "What have we learned?".

Addressing the major issues arising from the power ascribed to the Organization of the Petroleum Exporting Countries (OPEC), this book reflects the bredth, expertise and multifaceted viewpoints of the contributors: members of OPEC itself, industry representatives, and scholars and energy specialists from the USA, Europe and the Middle East. Throughout the book, the authors look at the potential of OPEC, discernible trends in such crucial areas as global petroleum supply and pricing, and the international economic and political implications of both.

Stock Analysis in the Twenty-First Century and Beyond For years, financial analysts have struggled with the fact that practically all the financial measures used to analyze corporate performance lack predictive power when it comes to forecasting the market performance of the company’s stock. Numerous academic studies have documented and reported this lack of predictability. Correlation coefficients close to zero have been reported for the relationship between stock market performance and such critical financial measures as earnings growth, sales growth, price/earnings ratio, return on equity, intrinsic value (models based on discounted cash flow or dividends), and many more. It is this disconnect between traditional financial measures and the performance of stocks in the marketplace that has led to the now-famous efficient market hypothesis, the cornerstone of modern portfolio theory. To accept the idea that the future performance of stocks is unpredictable is to say that nothing a company does will affect the future performance of its stock in the market, and that is absurd. It would be more accurate to say that everything a company does will affect the future performance of its stock in the market. The problem with this statement is that it makes the forecasting of future stock performance so complex that it removes it from the realm of human solution. Confident in the belief that something other than chance and irrational investors determine future stock prices, several research groups around the world have started exploring the use of intelligent computer programs (programs that self-organize based on environmental feedback). Early results are very promising and have provided a glimpse of the economic forces described by Adam Smith as the invisible hand that guides economic activity. Stock Analysis in the Twenty-First Century and Beyond describes the stock analysis problem and explores one of the more successful efforts to harness the new intelligent computer technology. Many people mistakenly classify Artificially Intelligent (AI) computer systems as a form of quantitative analysis. There are two distinct differences between advanced AI systems and traditional quantitative analysis. They are (1) who makes up the selection rules and weighting and (2) what information is used to discriminate between good- and poor-performing securities. In most quantitative systems, even in an advanced expert system form, humans make up the investment rules and mathematically derive the weightings associated with the rules. Computer systems that depend on outside human intelligence to program their actions are not inherently intelligent. In advanced AI systems, the computer makes up its own rules and weightings. The computer learns from examples of good- and poor-performing stocks and determines its own ways for discriminating between them. The procedures that are derived by the computer are often so complex that they defy human understanding. In addition to making up its own rules, advanced AI systems look at corporate financial data differently. Just like in the human brain, where information is not stored in the brain cells but rather in the connections and relationships between cells, so too is corporate performance information stored in the relationships between financial numbers. Assessing the performance of companies is not so much in the numbers as it is in the connections between the numbers. Financial analysts recognized this early on and have used first-order relational information in the form of financial ratios for many years (price/book, debt/equity, current assets / current liabilities, price/earnings, etc.). Now with advanced AI systems, we are finally able to look at and evaluate high-order interrelationships in financial data that have been far too complex to analyze with less sophisticated systems. These then are the fundamental differences between what has been used in the past and what will be used in the future. Cdr. Thomas E. Berghage
