Информационное общество: востребованность информационно-коммуникационных технологий населением России
The research probes the teaching and learning opportunities that the Wikipedia free Internet project provides in the area of project-learning. Using the platform as a tool gives students a chance to acquire and develop a variety of communicative and information processing competences that the article describes in detail. A variety of techniques using Wikipedia in the teaching process have been developed and tested in studying foreign languages, the humanities, and social sciences. We will be using the term 'wiki pedagogy' to describe the Wikipedia-based interactions between the teacher and the student; the term covers the information and communication technologies of education that are based on the Wikipedia platform
The article presents results from a cross-cultural study of the interrelation between the activity of Internet use and individual values of the highest order (S. Schwartz): “Self-Transcendence” — “Self-Enhancement” and “Openness to change” — “Conservation”. The data of the eighth wave of the European Social Research (ESS) was an empirical base of the study. In a comparative perspective, we analyzed the links between Internet use and values in Russia (N=2430), as well as in the three European countries that hold the highest rating in the field of information and communication technologies (ICT Development Index, 2017): Iceland (N=880), Switzerland (N=1519), and UK (N=1926). The data were processed using structural equation modeling (SEM) as well as multigroup structural equation modeling (MGSEM). The study showed that similar between Russia and European countries is the lack of connection between the activity of using the Internet with the values of “Self- Transcendence “, as well as a positive relationship with the values of “Openness to change”. Also, was found the following differences in patterns of relationships: on the sample of Russians value “ Self-Enhancement “ was associated positively with the activity of using the Internet, and on a sample of Western European countries this link is missing, but there is a negative relationship value, “Conservation”, away from the Russians. Based on the data obtained, we supposed how the values of Russians may change in the process of further digitalization of society and increasing involvement in the use of the Internet.
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.
