"Generic group algorithms solve computational problems defined over algebraic groups without exploiting properties of a particular representation of group elements. This is modeled by treating the group as a black-box. The fact that a computational problem cannot be solved by a reasonably restricted class of algorithms may be seen as support towards the conjecture that the problem is also hard in the classical Turing machine model. Moreover, a lower complexity bound for certain algorithms is a helpful insight for the search for cryptanalytic algorithms. Tibor Jager addresses several fundamental questions concerning algebraic black-box models of computation : Are the generic group model and its variants a reasonable abstraction? What are the limitations of these models? Can we relax these models to bring them closer to the reality?"

"Michie and Chambers’ BOXES methodology created a black box system that was designed to control a mechanically unstable system with very little a priori system knowledge, linearization or approximation. All the method needed was some notion of maximum and minimum values for the state variables and a set of boundaries that divided each variable into an integer state number. The BOXES methodology applies the method to a variety of systems including continuous and chaotic dynamic systems, and discusses how it may be possible to create a generic control method that is self organizing and adaptive that learns with the assistance of near neighbouring states."

"Rebekka Sputtek sheds light upon the question of how the personality and emotional traits of executives influence their decision making and leadership behavior. While recent strategic management research has started to recognize the relevance of an executive's personality traits as antecedents of organizational outcomes, this stream has called for a more fine-grained clarification of the psychological processes underlying executive decision making. In order to contribute to the understanding of these processes, a holistic model integrating the role of an expedient set of personality variables and anger in executive’s decision making comprehensiveness as well as authenticity of transformational leadership is developed."

"In 1953, South Korea was rated by the U.N. as the poorest country in the world. Five decades later, it is the fifteenth largest economy. Now, South Korea's decisions on how to manage its society and its role as a modern democracy while also establishing its policy regarding reunification with North Korea will determine where the country will go in the next fifty years. "The New Korea" examines the political, economic, industrial, and societal aspects of Korea today. Will it continue to enjoy an economic boom through new industries while competing against low-wage countries like China and India? Will it return to its role as a stomping ground for other powers? And what should Westerners pay attention to in terms of investment and business opportunities? As South Korea enters the most critical phase of its journey, it is crucial that we understand the factors involving its decisions and evolution. "The New Korea" is a fascinating account of what is and may become the state of this important region."

"Variable Rate Technology (VRT) offers an opportunity to improve production efficiency by allowing input applications to fluctuate in response to spatial variations in soil characteristics and nutrient levels. Society may also benefit from reduced negative externalities, such as surface and groundwater contamination, from input applications. Using a dynamic spatial model, this study examines how the interaction among variability, spatial autocorrelation, and mean level of soil fertility affects optimal sampling density and the economic gains from VRT. VRT was found to be profitable under selected conditions, and the optimal grid size will vary with these conditions. In the case where variability and mean fertility levels are significantly high associated with low spatial autocorrelation, VRT produces greater net returns than Uniform Rate Technology (URT), even with the smallest grid size to base the input application decisions. Results also demonstrate that optimal grid size increases with increased spatial autocorrelation."

""In this richly illustrated volume, Karl Ludvigsen takes the reader behind the scenes of the creation of the greatest V12 engines, recalling the effortless urge of the luxurious Hispano-Suiza of the 1930s and the scintillating surge of Lamborghini supercars of the 1960s. From exotic Auburns, Packards and Pierce Arrows in America to Europe's Ferraris, Lagondas and Delahayes, The V12 Engine is a lavish feast for car enthusiasts who relish the untold facts behind the story"--Provided by publisher."
