This book marries the expertise of a successful change management consultant with the proven leadership techniques of military thinkers to develop an imaginative and practical nine-step plan for any leader who wishes not simply to survive but to inspire and thrive "under fire".
Описание: Abstract: Measurements are presented and characterized of vertical electric fields 500 m from artificially initiated lightning return strokes and of voltages induced at both ends of a 448 m distribution power line by the same discharges, which are about 20 m from one end of the line. The experiment, which took place during the summer of 1986 at the NASA Kennedy Space Center, is described. The measured line voltages could be grouped into two categories, those in which multiple, similarly shaped, evenly spaced pulses were observed, which we call oscillatory, and those dominated by a principal pulse with subsidiary oscillations of much smaller amplitude, which we call impulsive. Voltage amplitudes range from tens of kilovolts for oscillatory voltages to hundreds of kilovolts for impulsive voltages. Contrary to what was expected, the voltage at the transmission line and farther from the lightning was found to be considerably larger than the voltage at the end nearer to the lightning. A new technique is derived for the calculation of the electromagnetic fields from nearby lightning over an imperfectly conducting ground. This technique is used in conjunction with a time domain coupling theory to calculate voltages at either end of the line. The results show fair agreement with the measured oscillatory voltage waveforms if corona is ignored and improved results when corona effects are modeled. Reasonable wave shape agreement is obtained for voltages of the impulsive type when these are modeled by the introduction of non-linear flashover effects, although unrealistically high return stroke currents are required to obtain good amplitude agreement. Suggestion for future experiments are given in the light of the present experience in measuring electric fields and their associated voltages from very close lightning.

Описание: The American English Compendium is a fun way to explore the nuances of the English language-learn that a group of lions is called a pride; a group of whales, a pod; and a group of owls, a parliament. This edition offers fresh chapters which include spelling, punctuation, and pronunciation; and even Twitterspeak and other online vernacular.

Описание: Nash equilibrium is the central solution concept in Game Theory.Since Nash's original paper in 1951, it has found countless applications in modeling strategic behavior of traders in markets, (human) drivers and (electronic) routers in congested networks, nations in nuclear disarmament negotiations, and more. A decade ago, the relevance of this solution concept was called into question by computer scientists, who proved (under appropriate complexity assumptions) that computing a Nash equilibrium is an intractable problem. And if centralized, specially designed algorithms cannot find Nash equilibria, why should we expect distributed, selfish agents to converge to one? The remaining hope was that at least approximate Nash equilibria can be efficiently computed.Understanding whether there is an efficient algorithm for approximate Nash equilibrium has been the central open problem in this field for the past decade. In this book, we provide strong evidence that even finding an approximate Nash equilibrium is intractable. We prove several intractability theorems for different settings (two-player games and many-player games) and models (computational complexity, query complexity, and communication complexity). In particular, our main result is that under a plausible and natural complexity assumption ("Exponential Time Hypothesis for PPAD"), there is no polynomial-time algorithm for finding an approximate Nash equilibrium in two-player games.The problem of approximate Nash equilibrium in a two-player game poses a unique technical challenge: it is a member of the class PPAD, which captures the complexity of several fundamental total problems, i.e., problems that always have a solution; and it also admits a quasipolynomial time algorithm. Either property alone is believed to place this problem far below NP-hard problems in the complexity hierarchy; having both simultaneously places it just above P, at what can be called the frontier of intractability. Indeed, the tools we develop in this book to advance on this frontier are useful for proving hardness of approximation of several other important problems whose complexity lies between P and NP: Brouwer's fixed point, market equilibrium, CourseMatch (A-CEEI), densest k-subgraph, community detection, VC dimension and Littlestone dimension, and signaling in zero-sum games.

Описание:
This is a much enlarged edition - with 4 further essays and a new introduction added - of Professor Rubinstein's influential study of the evolution and composition of Britain's elites since 1750.
The author is the leading historian who has reshaped our knowledge of the top strata of British society. He shows the key importance of London and of the relative insignificance of the manufacturing and heavy industries of the North of England for Britain's elite of wealth and power.
He focuses on the development of Britain's wealth and elite structures since industrialisation. The work is based on intense and original pioneering research into individual wealth-holders and elite members.
The essays include three which discuss 'survivals' in modern British history, patterns and movements which historians have overlooked because they 'shouldn't be there'.
A substantial new introduction reviews the recent historiography of the subject, and brings up-to-date earlier material.
Contents: New introduction; list of tables; Wealth: The Victorian Middle Classes: Wealth, Occupation and Geography; Wealth, Elites and the Class Structure of Modern Britain; The Geographical Distribution of Middle-class Income in Britain, 1800-1914; Entrepreneurial Effort and Entrepreneurial Success: Peak Wealth-holding in Three Societies, 1850-1939. Elites: New Men of Wealth and the Purchase of Land in Nineteenth-Century Britain; Education and the Social Origins of British Elites, 1880-1970; The Evolution of the British Honours System Since the Mid-Nineteenth Century; Survivals: The End of 'Old Corruption' in Britain, 1780-1860; Charles Dickens, R. Austin Freeman and the Spirit of London; British Radicalism and the 'Dark Side' of Populism.
Additional essays: The Social Origins and Career Patterns of Oxford and Cambridge Matriculants, 1840- 1900; The Size and Distribution of the English Middle Classes in 1860; Businessmen Into Landowners: The Question Revisited; The Secret of Leopold Amery.

Описание:
The academy is often described as an ivory tower, isolated from the community surrounding it. Presenting the theory, vision, and implementation of a socially engaged program for the Department of Human and Organizational Development (HOD) in Peabody’s College of Education and Human Development at Vanderbilt University, Academics in Action! describes a more integrated model wherein students and faculty work with communities, learn from them, and bring to bear findings from theory and research to generate solutions to community problems. Offering examples of community-engaged theory, scholarship, teaching, and action, Academics in Action! describes the nuanced structures that foster and support their development within a research university. Theory and action span multiple ecological levels from individuals and small groups to organizations and social structures. The communities of engagement range from local neighborhoods and schools to arenas of national policy and international development. Reflecting the unique perspectives of research faculty, practitioners, and graduate students, Academics in Action! documents a specific philosophy of education that fosters and supports engagement; the potentially transformative nature of academic work for students, faculty, and the broader society; and some of the implications and challenges of action-oriented efforts in light of dynamics such as income inequality, racism, and global capitalism. This edited volume chronicles teaching, research, and community action that influences both inside and outside the classroom as well as presents dimensions of a participatory model that set such efforts into action.
