This textbook explains the modern mathematical approaches to describing discrete mathematical objects, constructing and studying applied discrete mathematical models, suiting the needs of socio-economical and socio-political life of contemporary society. The presented material is illustrated with examples from modern Russian and foreign practice. For example, estimates of influence of groups and fractions in the Russian Parliament and the Council of Ministers of EU are examined. The book is supplemented with a great number of problems and exercises with solutions and answers, as well as problems for independent solving.Addressed to higher education students in the areas of economics, business informatics, political science, public administration.
This book directly confronts uncomfortable questions that many prefer to brush aside: if economists and other scholars, politicians, and business professionals understand the causes of economic crises, as they claim, then why do such damaging crises continue to occur? Can we trust business and intellectual elites who advocate the principles of Realpolitik and claim the "public good" as their priority, yet consistently favor maximization of profit over ethical issues?
Former deputy prime minister of Russia Grigory Yavlinsky, an internationally respected free-market economist, makes a powerful case that the often-cited causes of global economic instability—institutional failings, wrong decisions by regulators, insufficient or incorrect information, and the like—are only secondary to a far more significant underlying cause: the failure to understand that universal social norms are essential to thriving businesses and social and economic progress. Yavlinsky explores the widespread disregard for moral values in business decisions and calls for restoration of principled behavior in politics and economic practices. The unwelcome alternative, he warns, will be a twenty-first-century global economy in the grip of unending crises.
Grigory Yavlinsky is a Russian economist and founder and member of the Russian United Democratic Party (YABLOKO). As deputy prime minister of Russia in 1990, he wrote the first Russian economic program for transition to a free-market economy, 500 Days. He lives in Moscow.
“Grigory Yavlinsky’s book is an important contribution to understanding the interplay between social norms and modern economy. The current global crisis makes his analysis especially relevant.”—George Soros
“Reading Grigory Yavlinsky's remarkable book, I was reminded of Adam Smith, also a moral philosopher concerned with the correlation between individual aspirations and the enlightened evolution of society. It is invaluable to have the perspective of an intellectual such as Yavlinsky writing in the shadow of swiftly moving events on the global stage. He explains how market mechanisms influence international developments ranging from instability in European markets to the recent ‘Great Recession’ in the United States.”—Vartan Gregorian, President, Carnegie Corporation of New York
“Yavlinsky provides a new and in-depth interpretation of the events leading to the current recession and broader interpretations of how to avoid future ones. Realeconomik has my enthusiastic endorsement.”—Michael D. Intriligator, University of California, Los Angeles
“With clarity and eloquence, Yavlinsky argues that the deepest cause of the global recession was the erosion of the world economy’s moral dimensions. As a professional economist who has long been a leader of the Russian opposition, he knows how to splice politics and economics. As a politician who has repeatedly declined high office on grounds of principle, he lends the book additional authority. Realeconomik is a work that will, I believe, help to spark a public debate on issues of profound importance for humankind.”—Peter Reddaway, George Washington University
In article the concept of a special economic zone (OEZ), key principles of its organization, specifics of the OEZ organization for tourism development are considered, the analysis of world experience of creation and functioning of tourist and recreational OEZ in Panama, China and on Philippines is given.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
