The study of factors and motivesfor forming qualification deficits and educational demands of University middle managers in the context of knowledge management, practical significance, the results of which is the solution of the problem of management accounting and the effectiveness of professional interaction of managers in the transition to the project type of professional activity and obtaining additional resources for the development of the University. Innovation, in the context of the non-linear nature of the University as an educational organization and the basic processes of its life, the article postulates as a nonlinear phenomenon that is required for the generation and implementation of adequate forms of University management, which provides project management. The process of updating the sources of University managers qualification as the basis of efficiency and productivity of University management, considered in the article to the context of knowledge management, allowed not only to offer ways of direct overcoming of the identified qualification deficits that can be overcome with the help of certain educational programs, but also to determine the basis for the formation of productive management project teams based on the use of the strengths of University managers, which in turn contribute to the generation of, develop and implement internal and external innovative university projects.
The participants of discussion review the thesis that economic development explains the rise and persistence of democracy, often referred to as the “Lipset thesis” after Seymour Lipset’s 1959 article. Most of the authors suggest that modernization theory in its most “simple version” rests on shaky empirical foundations. That is, at best there seems to be limited evidence in favor of the hypothesis that a change in income in a given year produces an unconditional, instantaneous change in the likelihood of democracy. Several of the contributions point to substantial evidence in favor of a more refined version of modernization theory, suggesting that increasing income promotes democracy i) in the medium or long-term and ii) conditional on certain “triggers” of authoritarian regime breakdown. It should be noted that there seems to be more evidence in favor of a link between income and democratic sustainability (“Przeworski thesis”). When considering democratic survival, income may even have an unconditional effect and an instantaneous effect. C. Welzel sketches how increases in material resources (such as money) and cognitive resources (such as education) shifts people’s preferences from existential concerns to freedom and self-realization – as part of “emancipative values”. D. Acemoglu and J. Robinson claim that there is no tendency for countries to become more democratic as they become more ‘modernized’ whether in terms of higher levels of income per-capita or education. The initial conditions created inclusive or extractive institutions which then put the societies onto very different long run paths of modernization and development. G. Munk declares that the majority of studies go against the expectations of modernization theory, suggesting that there is no positive or a negative income-democracy link. He concludes that modernization theory is a failed theory. We need to set it aside and move on to more promising avenues of research.
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.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Let G be a semisimple algebraic group whose decomposition into the product of simple components does not contain simple groups of type A, and P⊆G be a parabolic subgroup.
