The content of the course unit Contemporary Concepts of Natural Science is of great importance in the common cultural and common professional training of a Clinical Psychology specialist. Conceptual bases of the educational process realization of the course unite Contemporary Concepts of Natural Science reflect modern scientific beliefs about its essence, content and specificity. The theory of gradual formation of mental operations and notions is to the most extent appropriate for the formation of common cultural and common professional competencies.

The Impact

AbstractRailway systems occasionally get into a state of being out-of-control, meaning that barely any train is running, even though the required resources (infrastructure, rolling stock and crew) are available. Because of the large number of affected resources and the absence of detailed, timely and accurate information, currently existing disruption management techniques cannot be applied in out-of-control situations. Most of the contemporary approaches assume that there is only one single disruption with a known duration, that all information about the resources is available, and that all stakeholders in the operations act as expected. Another limitation is the lack of knowledge about why and how disruptions accumulate and whether this process can be predicted. To tackle these problems, we develop a multidisciplinary framework combining techniques from complexity science and operations research, aiming at reducing the impact of these situations and—if possible—avoiding them. The key elements of this framework are (i) the generation of early warning signals for out-of-control situations, (ii) isolating a specific region such that delay stops propagating, and (iii) the application of decentralized decision making, more suited for information-sparse out-of-control situations.
