Implications and Preventions of Cyberbullying and Social Exclusion in Social Media: Systematic Review

Background The growth of social networking has created a paradigm in which many forms of personal communication are being replaced by internet communication technologies, such as social media. This has led to social issues, such as cyberbullying. In response, researchers are investigating cyberbullying to determine its implications in various life sectors. Objective This manuscript reviews the methods, results, and limitations of the current cyberbullying research and discusses the physical and mental repercussions of cyberbullying and social exclusion as well as methods of predicting and counteracting these events. On the basis of the findings, we discuss future research directions. Methods Using ScienceDirect, ACM Digital Library, and PubMed, 34 research articles were used in this review. A review was conducted using the selected articles with the goal of understanding the current landscape of cyberbullying research. Results Studies have analyzed correlations between depressive and suicidal ideations in subjects as well as relationships in the social, educational, and financial status of the perpetrators. Studies have explored detection methods for monitoring cyberbullying. Automated detection has yet to become effective and accurate; however, several factors, such as personal background and physical appearance, have been identified to correlate with the likelihood that a person becomes a survivor or perpetrator of web-based cybervictimization. Social support is currently common in recovery efforts but may require diversification for specific applications in web-based incidents. Conclusions Relations between social status, age, gender, and behaviors have been discovered that offer new insights into the origins and likeliness of cyberbullying events. Rehabilitation from such events is possible; however, automatic detection is not yet a viable solution for prevention of cyberbullying incidents. Effects such as social exclusion and suicidal ideations are closely tied to incidents of cyberbullying and require further study across various social and demographical populations. New studies should be conducted to explore the experiences of survivors and perpetrators and identify causal links. The breadth of research includes demographics from China, Canada, Taiwan, Iran, the United States, and Namibia. Wider ranges of national populations should be considered in future studies for accurate assessments, given global internet communication technology activity. The studies emphasize the need for formal classification terminology. With formal classification, researchers will have a more definite scope, allowing specific research on a single definable topic rather than on general bullying events and symptoms. Of all the studies, 2 used a longitudinal design for their research methodology. The low number of longitudinal studies leaves gaps between causation and correlation, and further research is required to understand the effects of cyberbullying. Research addressing ongoing victimization is required for the various forms of cyberbullying; social support offers the most effective current standard for prevention.

The Walking Robot Control System that is Adaptive to Changes in the Kinematics

The walking mobile robots (WMR) have recently become widely popular in robotics. They are especially useful in the extreme cases: search and rescue operations; cargo delivery over highly rough terrain; building a map. These robots also serve to explore and describe a partially or completely non-deterministic workspace, as well as to explore areas that are dangerous to human life. One of the main requirements for these WMR is the robustness of its control system. It allows WMR to maintain the operability when the characteristics of the support surface change as well as under more severe conditions, in particular, loss of controllability or damage of the supporting limb (SL). We propose to use the principles of genetic programming to create a WMR control system that allows a robot to adapt to possible changes in its kinematics, as well as to the characteristics of the support surface on which it moves. This approach does not require strong computational power or a strict formal classification of possible damage to the WMR. This article discusses two main WMR control modes: standard, which accord to a serviceable kinematics, and emergency, in which one or more SL drives are damaged or lost controllability. As an example, the structure of the control system of the WMP is proposed, the kinematics of which is partially destroyed in the process of movement. We developed a method for controlling such robot, which is based on the use of a genetic algorithm in conjunction with the Mealy machine. Modeling of modes of movement of WMR with six SL was carried out in the V-REP program for two cases of injury: absent and not functioning limb. We present the results of simulation of emergency gaits for these configurations of WMP and the effectiveness of the proposed method in the case of damage to the kinematic scheme. We also compared the performance of the genetic algorithm for the damaged WMR with the standard control algorithm.

COMPLEX CLASSIFIERS OF FORMAL CLASSIFICATION THEORY OF TECHNICAL SYSTEMS: HIERARCHO-MATRIX, ZONE, CYCLIC

The article highlights the different aspects of complex technical systems that can be ordered and classified in accordance with the totality, structure and values of the attributes characterizing these systems by a unified approach to various types of classifications. The most complex classifiers studied in this work are hierarchical-matrix, cyclic and zonal classifiers. Zones are the areas identified in the space of classification attributes that characterized by a similar value of an additional target classification attribute. The dimension of the zonal classification is equal to the number of descriptive classification attributes, the zonal dimension is equal to the number of zones. Adding the zones is carried out according to the target classification criterion, multiplying the zones consists in introducing the new descriptive classification attributes. Cyclicity is repetition of the similar elements that occurs in the space of physical quantities or other parameters. The concept of cycle stages is defined for all cycles, which is a specific (target) classification attribute. The internal dimension of the cycle is equal to the number of stages, the external dimension is equal to the number of acts of the cycle, the descriptive dimension is equal to the number of descriptive classification attributes. Addition of cycles can be carried out both by stages and by descriptive features and consists in increasing the number of values of classification attribute. Multiplication of cycles consists in the introduction of new descriptive classification attributes. Zonal and cyclic classifiers are widely used in the practice of describing and planning technical energy systems. A wide range of classifiers ordered from the standpoint of a unified formal theory of classification will take into account the features of specific technical systems, the conditions for the objects functioning, the context of the interpretation area. As a re-sult, the degree of adequacy of classifiers to the diversity of the interpretation area objects and the representativeness of models based on classifiers will increase

Neolithic ceramic complex of the settlement of Mergen 6 in the Lower Ishim (groups I and II): characteristics and interpretation

The article discusses a ceramic complex (groups I and II) of the early Neolithic settlement of Mergen 6 (Lower Ishim River region, Western Siberia, 7th millennium BC). The aim of the work is to analyze the materials from the perspective of the cultural and chronological correlation of the Boborykino and Koshkino antiquities of the Trans-Urals. The research is based on the elements of the historical-cultural and formal-classification ap-proaches. The source base consists of 236 vessels. As a result of the analysis carried out in several stages (mor-phology of the vessels, tool and technique for applying ornamentation, structural components of the decor, nature of the system organization of the ornamental components, relationship of the image components with the struc-ture of the vessels' shape), it was found that the products of group I correspond to the Boborykino cultural tradi-tion, and group II — to the Koshkino. The simultaneous occurrence of these vessels made it possible to speak of the coexistence within the same society of representatives of the traditions of their manufacture. On this basis, there has been proposed a clarification of several positions regarding the pattern of the cultural and chronological development of the Boborykino antiquities in the Trans-Urals. The emergence of an early flat-bottomed ceramic complex in the River Ishim region allows it to be included in the range of materials of a similar appearance (Saty-ginsky, Mulymyinsky, Amninsky, Kayukovsky, Barabinsky) identified in the mountain-forest Trans-Urals, Kondin-sky lowlands, Irtysh River region and Baraba. Identification of the Mergen vessels of group I as belonging to the Boborykino Culture, dating from the Early Neolithic, makes it possible to pose the question of identifying the early phase of the antiquities of this cultural group. Location of the Koshkino and Boborykino groups of vessels in the same sites attests to the coexistence and contacts of the two traditions and their mutual influence.

The concept of «property» (according to the practice of the European court of human rights)

The article is devoted to the autonomous meaning of the term «property» used by the European Court of Human Rights. Emphasis is placed on the fact that in national legal systems, approaches to defining the concept of proper-ty, property rights have been and remain different. The violation of property as ownership exclusively of material things, excluding other rights and interests (substantive legal interests), the application of a formal classification of objects of law leads to violations of the right of everyone to own, use and dispose of their property by public author-ities and local governments. property. As the judgment of the European Court of Human Rights is a source of law in the member states of the Council of Europe, national law cannot contradict the Convention and the case law of the European Court of Human Rights.It is noted that the European Court of Human Rights, applying the autonomous meaning of the term «proper-ty», which does not depend on the formal classification of property rights in the national legislation of the mem-ber states of the Council of Europe, applies the following approaches to the concept of «property», the concept and content of property rights. that would be compatible with national legal systems. As a result of the analysis of the case law of the European Court of Human Rights, it was established that «property» is: 1) ownership of existing material things; 2) assets, including claims that the entity can claim to have at least a «legitimate ex-pectation» that they will be realized; 3) other rights and interests that constitute assets and can be considered as «property rights». Property that falls within the scope of Art. 1 of Protocol No. 1 to the Convention for the Protection of Human Rights and Fundamental Freedoms constitute, inter alia, economic resources to which natural persons have no registered property rights, but which have originally belonged to their ancestors and parents for economic activities, as well as income that individuals receive from the use of these resources.

BASIC CLASSIFIERS OF FORMAL CLASSIFICATION THEORY OF TECHNICAL SYSTEMS: HIERARCHIES, VECTORS AND MATRICES, BANDS

The article considers the importance of a technical system among other technical systems in order to ensure its functioning and development, to classify objects, subjects, processes of the technical and related systems. Previously, the author presented the basics of the formal classification theory. This article describes the basic classifiers and operations with them. Three types of basic classifications are identified: discrete hierarchical, discrete matrix and continuous band classifications. For them the concept, structure, dimension, basic operations (addition, multiplication, equality) are defined. In the hierarchy, the classification attributes can be sorted by subordination, when the classification attributes of the lower levels of the hierarchy detail the features of higher levels. The dimension of the hierarchical classification is the number of levels of classification features. Matrix classifications (including vector and super-matrix) are used when the classification attributes are equal and their values are discrete. Band classifications are similar in structure to matrix classifications, but the value of the classification attribute is the interval of numbers, for which the lower and upper boundaries are determined. The dimension of the matrix and band classifications is equal to the number of non-subordinate classification attributes. For all classifications, multiplication is equivalent to the introduction of new classification attributes, addition is the introduction of new values of already existing classification attributes. A unified approach to various types of classifications makes it possible to plan the structure of classifications of specific technical systems, taking into account the properties of characteristic parameters

PRINCIPLES OF FORMAL CLASSIFICATION THEORY OF TECHNICAL SYSTEMS: CASE OF ENERGY FACILITIES

The article describes the power generating and other energy facilities as complex technical systems interacting with the material, financial, informational and legal environment. To ensure functioning and development of a technical system it is important to determine its place among other technical systems: technical systems and their elements must be classified. There have been presented the principles of formal theory of technical system classification. The classification objects have been given a definition. The concepts of classification, classification attribute and meaning of the classification attribute are formalized. The goal and tasks of the classification are formulated. The stages of forming and applying classifiers include developing the composition and structure of classifier kernel, marking interpretation elements and selecting an element corresponding to the user's request. The alphabet, inference rules, axioms and main theorems of the classification formal theory are presented. It is proved that a complete consistent independent classification theory is decidable. The taxonomy of the classifier types is considered: elementary (incomplete and complete), basic (discrete hierarchical, discrete matrix, continuous band), complex (combined and limiting). Examples of using classifiers of various types in the description of energy objects are given. The algorithms, labeling and selection problems are considered. The use of a grounded and structured classification theory allows better understanding and description of the relationship between technical and related systems and l increases the efficiency of functioning and development of technical systems.
