When pedestrians walk along a corridor in both directions, a frequently observed phenomenon is the segregation of the whole group into lanes of individuals moving in the same direction. While this formation of lanes facilitates the flow and benefits the whole group, it is believed that results from the actions of the individuals acting on their behalf, without considering others. This phenomenon is an example of self-organization and has attracted the attention of a number of researchers in diverse fields. We introduce and analyze a simple model. We assume that individuals move around a multi-lane circular track. All of them move at the same speed. Half of them in one direction and the rest in the opposite direction. Each time two individuals collide, one of them moves to a neighboring lane. The individual changing lanes is selected randomly. We prove that the system self-organizes. Eventually, each lane is occupied with individuals moving in only one direction. Our analysis supports the belief that global self-organization is possible even if each member of the group acts without considering the rest.

AbstractCellulose-based systems are useful for many applications. However, the issue of self-organization under non-equilibrium conditions, which is ubiquitous in living matter, has scarcely been addressed in cellulose-based materials. Here, we show that quasi-2D preparations of a lyotropic cellulose-based cholesteric mesophase display travelling colourful patterns, which are generated by a chemical reaction-diffusion mechanism being simultaneous with the evaporation of solvents at the boundaries. These patterns involve spatial and temporal variation in the amplitude and sign of the helix´s pitch. We propose a simple model, based on a reaction-diffusion mechanism, which simulates the observed spatiotemporal colour behaviour.

Introduction. The paper addresses the issue of support of the students involved in a fully online retraining program, which imposes special requirements on the development of the self-education ability. The study aims to establish the conditions for organizing the support of self-education in a digital educational environment. Materials and methods. The study relies on the methodology proposed by G.N. Prozumentova for reconstructing the innovative experience to analyze the reflexive text materials of the Logbook of students of the retraining program; to identify the points of stress, misunderstanding, breaks, and transitions during training; and make an analytical generalization. Results of the study. Categories of difficulties encountered by students of the program in their self-educational activity were identified, and the conditions necessary to support self-education were established. These are points of self-determination, professional trials, points of reflection, and individual educational route. Conclusion. In the context of restrictive measures during the pandemic and the transition to the online educational process, self-skills related to self-education, i.e., self-organization, independence, and self-determination, become essential. These competences are an indispensable part of the work of a tutor. However, before the tutor can support someone, they need to build these self skills themselves. The established conditions in the retraining programs will facilitate this process. At the same time, additional studies are required to reveal in more detail the individual progress of a person under these conditions for building a model for supporting the development of self-education ability, and to determine the methods for tutors to provide the support of this progress. Keywords. Self-education, self-determination, individual educational route, professional retraining, tutor, digital environment, self skills.

The paper considers various approaches to studying the self-organization of students’ educational activity, the assumption about the interrelation of self-organization of educational activity and time perspective of the individual is made. The importance of self-organization of educational activity in the modern education system of higher education institutions comes to light. Stages of formation of self-organization and possible difficulties which a person can face are sorted out. Results of basic research of the time perspective and self-organization of university students are stated. The interrelation between commitment and alloted time is defined, as well as regularity, emotional coloring of time, structure of time and feeling of time. The received results specify the possible directions of the organization of forms of psychological support of university students having problems with self-organization of time in the educational process.

The authors analyze the stated problem in philosophical, historical, psychological and pedagogical aspects, clarify the conceptual apparatus of the research, determine the structural components of the personality of a technical university student with self-organization culture, describe the developed structural and functional model of the formation of self-organization culture of a technical university student, implemented on the example of humanities disciplines, substantiate the set of pedagogical conditions of the considered process. The main goal of personal self-organization is to control one’s life on the basis of optimal use of available opportunities and taking into account individual characteristics and abilities. It is determined that all this requires the individual to make efforts to restructure his or her life activities and involves self-reflection, self-monitoring and self-correction of behavior.

Complex social animal groups behave as self-organized, single structures: they feed together, they defend against predators together, they escape from perturbations and disperse and migrate together and they share information. It is modestly evident that many individuals sharing information about their environment may be more successful in coping with perturbations than solitary individuals gathering information on their own. The group exists for and by means of all the individuals, and these exist for and by means of the group. Social groups have emergent properties that cannot be easily explained by either selection or self-organization. Yet, sociality has been shaped by the two forces. How sociality has evolved by selection is puzzling also because it confronts the benefits of the group versus the benefits of the individual, which is a historically debated theme. There are many other open questions about sociality that I have explored in this book. But in the end, the process that has fascinated me the most is social copying. Despite the sophisticated mechanisms evolved in increasing information in social groups—which has culminated in humans with language and technological interconnections—it is impressive how a simple behaviour such as social copying has maintained its strength when individuals make any kind of decisions, from insignificant to transcendent....

The social and didactic dynamics produced in implementations of the negotiation-oriented and partly web-based game “Surfing Global Change” (SGC) was analyzed by independent experts after their observations in advanced interdisciplinary university courses. It could be empirically demonstrated that the intended didactics of SGC were successful; namely that they were grounded on “active, self-organized learning”, training of “competence to act” and on responsibility for both practicable and sustainable solutions for the future society. The outlay of SGC succeeds in equilibrating competition vs. consensus, self-study vs. team work, sharpening the individual standpoint vs. readiness to compromise, differentiation into details vs. integration into a whole and hence mirrors professional realities. In this spirit, the architecture of SGC gives a framework for “game based learning” along its five interactive game levels. The conclusion is made that the set of game rules acts as a boundary condition for expected processes of social self-organization. The independent expert opinions express the importance of self-responsibility, for example when defining team size (ideally 3-5), during the identification of students with a project relevant to real life, and with the trainer staying on the meta level without entering into student discussions. Hence, self-organization in SGC allows for self-responsibility.

We consider the problem of reorganizing a linear list, when the individual queries consist of accesses to a subset of the elements stored, as opposed to the individual elements themselves. In this paper, which to our knowledge represents the first reported result in this model of query processing, we first propose a simple model for a query generator which emits set queries. Subsequently, we present extensions to the classical move-to-front (MTF) and transposition (TR) rules under this generalized query generation mechanism and analyze their performance.

This article aims to establish how an idea becomes an innovation and how creativity, collective dynamics, and information are interconnected. The results of the author's study showed that the emergence of innovations is closely connected with collective collaboration, and that it is impossible outside of group dynamics. The process of self-organization and collective decision-making is realized through a synergistic interaction, which then transforms into the so-called “information laser” and serves as a basis for the emergence of innovation. Both individuals, as persons and as separate entrepreneurs, are the elements of the innovation system and the actors of the artificial neural network, socio-economic neural systems (SENS-systems). These systems act through self-organization and corporate collaboration, and the efforts of each element are amplified through the interaction with the other elements. The model of the SENS-systems can explain how the individual idea transforms into innovation and spreads throughout the world.
