Aim. To promote a better understanding, a wider and more correct application of the effectiveness retention ratio. That is the measure that is best suited for assessing the dependability of complex technical systems, in which partial failures are possible that put a system into intermediate states between complete up and down ones. Methods. The paper uses the methods of the probability theory and comparative analysis of texts of interstate (Euro-Asian), Russian and international dependability-related standards. Results. The principal contribution of Russian researchers to the creation and development of methods for applying effectiveness indicators to estimating the dependability of complex systems is pointed out. Shortcomings were identified in the basic dependability-related standards as regards the effectiveness retention ratio and related concepts. Namely, in terminology standard GOST 27.002–2015, the phrases that require improvement are indicated. They relate to the concepts of partial failure, partial up state and partial down state. A broader and more ac[1]curate definition of partial failure is suggested. It is noted that the relationship between partially up and partially down states are to be discussed and clarified. GOST 27.003–2016 that establishes the content and general rules for specifying dependability requirements contains wording errors in the classification of items according to the number of possible (taken into consideration) states and in the examples of possible variants of the effectiveness retention ratio in various branches of technology that are probabilities of task completion, etc. The paper suggests corrections to the appropriate wordings. It has been established that although the effectiveness retention ratio is not referred to in the international dependability-related terminology standard (IEC 60050-192:2015), it implicitly appears in two IEC standards (IEC 61703:2016 and IEC 62673:2013), in which it is assigned to availability measures. Conclusion. The paper’s findings will be useful to experts involved in the assessment and standardization of complex technical system dependability. Their implementation will help improve interstate, Russian and international dependability-related standards.

The article reviews the definitions of the tutoring concept in preschoolers relationships. Can we qualify the relationships of preschool children in learning situations as tutoring? Or maybe a different name would be more suitable for them? Preschoolers are used to learning in a different way than adults and older children. They prefer learning mimicking or playing. They obtain knowldge occasionally an unintentionally. In turn, definitions of tutoring quite precisely contain formulated fortifications that a little child is not able to meet yet. Immaturity of the nervous system limit the level and length of attention span of little child and relatively small, compared to school children and adults number of social experiences can seriously hamper the classification of situations in which children learn from each other as tutoring. While the generally understood master-student relationship, associated with tutoring, is quite often noticeable during childhood collaboration and play in which one child can do more than the other, the more detailed assumptions of tutoring are not as accessible to the observer. For example, it is difficult to talk about the regularity or planned nature of children's relationships. The definition of tutoring also sets specific expectations regarding the teacher's skills, among which are: high interpersonal competences, commitment to the relationship with the mentee, professionalism and responsibility. From a preschool child who would play the role of a teacher, it is difficult to demand fluent speech, not to mention professionalism and regularity. A preschool child, who just start to learn numbers, is often unable to orient himself in time, which makes it difficult or even impossible to plan and systematize his activities. Little child needs adult help in this area.

Managerial innovations have become the topic of interest for many scholars, but this concept remains underdeveloped and poorly managed among the academy and business community in Russia. This paper offers the composition of approach to definition and classifi cation of managerial innovations, formed on the basis of exploration of the concept “managerial innovation” evolution, and estimation of the relationship with a more general concept “innovation”. The suggested composition of approach is based on the three-stage bibliographic analysis of scientific literature. In course of the bibliographic research, scientific articles were selected according to the key words, period of publication and citation index. 140 scientific publications were identified and collected for the period from 1975 to 2019 covering citation indexes from 0 to 12 476 by Web of Science citation database and from 4 to 2 185 by Scopus database. On the basis of the conducted bibliographic research, the author introduces his definition of innovation and managerial innovation and explains the connection between them. Within the conducted research different approaches to classification of managerial innovations were studied and on their basis a new approach to classification of managerial innovations was proposed. The findings can be useful for different avenues of further research regarding managerial innovations.

The subject offorensic examination as a practical activity is one of the most important categories offorensic examinations theory. The subject offorensic examination is used to classify forensic examinations. The definition of the subject offorensic examinations through the prism of information theory categories is the most productive. Information is a part of the data about the investigated object which is used to solve a particular task. Legal information is used during investigation of crimes. The author proposes a classification of legal information. Information is divided into criminally relevant and neutral, depending on the relationship of the data to the event of the crime. Information is procedural or nonprocedural, depending on the method of receipt in accordance with the procedural law. Information is evidentiary if it presents the content of evidence by itself. Information is orienting when it’s used for organizational or tactical purposes. Information is criminalistic, expert or operative-search, depending on the methods and subjects of its receipt. Information, received by the expert during the investigation, is criminally relevant or neutral, procedural, expert, evidentiary or orienting. The data that are received by an expert, become useful information if they help to resolve issues put to a forensic expert. A special object of forensic examination (information field) is the totality of homogeneous properties of the subsumer. The direct object of an expert research is a part of a special object that is subjected to research during a specific expert study. The subject of forensic examination kind is evidentiary and orienting information that can be obtained at the contemporary stage of forensic examination development by researching a special object that is a part of the object properties offorensic examination kind. The subject ofparticular forensic examination is evidentiary or orienting information, which must be obtained by an investigation of a direct object that is the part of the properties of the particular material carrier submitted for examination.

A firewall is the main classic tool for monitoring and managing the network traffic on a local network. Its task is to compare the network traffic passing through it with the established security rules. These rules, which are often also called security policy, can be defined both before and during the operation of the firewall. Managing the security policy of large corporate networks is a complex task. In order to properly implement it, firewall filtering rules must be written and organized neatly and without errors. In addition, the process of changing or inserting new rules should be performed only after a careful analysis of the relationship between the rules being modified or inserted, as well as the rules that already exist in the security policy. In this article, the authors consider the classification of relations between security policy rules and also give the definition of all sorts of conflicts between them. In addition, the authors present a new efficient algorithm for detecting and resolving collisions in firewall rules by the example of the Floodlight SDN controller.

The Amaral Formation has a wide geographic distribution within the Lusitanian Basin, at the western Iberian Margin (Portugal). The different depositional contexts for this unit enabled the distinction of three sectors: lagoon, lagoon-barrier, and marine-distal. The integration of the evolutionary taphonomic analysis of its fossil assemblages with the analysis of multiscale properties through the CAMURES methodology (Multiscale Reservoir Characterization) allowed the application of a methodology for the classification of coquina which was previously developed for the Morro do Chaves Formation (Sergipe–Alagoas Basin, Brazil). Here, it was adapted according to the complexity of the Amaral Formation deposits. The classification of ten taphofacies, in association with four lithofacies, allowed the definition of 84 petrofacies, based on the nature of the sedimentary and taphonomic processes. The relationship between the structural context, the systems tracts, the diversity of the fossil record, the classification of taphofacies and petrofacies, and the understanding of vertical and lateral variations of the sediments’ deposition within the unit support the construction of geological and theoretical models for coquina deposits. These models will allow for prediction of the spatial distribution of facies in other coquina analogous hydrocarbon reservoirs, as well as specifying the delimitation of reservoir zones for 3D geocellular modeling and flow simulation of hydrocarbon-producing reservoirs, thus improving predictive analyses.

Program classification is an important tool for records and marketing. Accessible, reliable, and internationally comparable data is needed in all aspects of work. And this is not only a matter of program organisation but also a fundamental part of the research of the audience in terms of studying the relationship between the public and the programs. A typology can be created according to the motives and habits, underlying the behavior of the viewer as a buyer with regard to their television preferences. It can be first considered whether the viewer is watching TV carefully or in parallel with other things, constantly changing channels, or watching a selected channel continuously. The demographic approach is formed by derived indicators and estimates, which allows to comprehensively characterize the structure and movement of the population, social, and demographic processes. In the case of studying television audiences, it is more common to deal with indicators of the number of people, gender, age, state of marriage, level of education, profession, social status, income. A TV set, a computer, a tablet, a smartphone - all this is now television. Arranged on the air according to the broadcasting grid, we watch television programs at home; it is called linear viewing. However, we can also request the content we are interested in on any screen at any time, anywhere - this is non-linear viewing. Recently, in connection with the Covid-19 pandemic, even journalists have been broadcasting from home. It used to be just television but nowadays the definition of "big television" has come into use. Television is primarily what it shows - television content that has certain characteristics. The usual division is based on the basic functions of television - informative, entertaining, and educational. However, a lot depends on the idea, thematic focus, genre structure, origin, format, and content. The division is necessary for a greater understanding of what exactly we intend to produce according to the formula: there is an idea, what the manufacturer wants to convey to the audience, after, it is necessary to understand how it can be made and with what content filled directly. This article deals with approaches to the classification of television programs.

Abstract This paper aims at giving an up-to-date picture of compounding in Italian on the basis of most recent literature. First and foremost, we illustrate the basic units of Italian compounds, including semiwords, and we offer an operational definition of compounding that will be adopted throughout the paper. Secondly, we focus on the crucial issue of the demarcation of compounds: several criteria are given to distinguish compounds from derived words, phrases and also phrasal lexemes. Third, we offer a classification of Italian compounds according to two hierarchically ordered criteria – the grammatical relation between the constituents and the presence/absence of the head – and then we illustrate the main formation patterns that give rise to such compounds. Finally, we discuss crucial theoretical issues such as headedness and the relationship between compounding and inflection.

Social Identity Theory contains two seemingly incompatible predictions regarding the relationship between self-esteem and ingroup bias. The first focuses on low self-esteem as motivation for bias, predicting that low self-esteem individuals exhibit more ingroup bias. The second posits that high self-esteem results from exhibiting bias, thus, high self-esteem individuals exhibit greater bias. A meta analysis examined the relationship between self-esteem and ingroup bias. Additionally, the project examined methodological issues such as the lack of consistency in measurement of self-esteem, artificial dichotomization of self-esteem scores, classification of individuals as low self-esteem, and theoretical considerations such as the use of different ingroup bias strategies and the role of social category salience. Thirty-four studies yielding 102 effect sizes from 6660 subjects were included in the analysis.Results indicated a consistent pattern whereby high self-esteem individuals exhibited more ingroup bias than did individuals with low self-esteem. However, this result was moderated by ingroup bias strategy. When using ingroup bias strategies that required ratings of ingroup superiority, high self-esteem individuals showed more ingroup bias than individuals with low self-esteem. However, when using "indirect" strategies, such as rating groups that the individual did not contribute to, differences between low and high self-esteem individuals were not found. This result leads to the conclusion that both groups exhibit ingroup bias; however, individuals with low self-esteem are limited in the types of bias they exhibit. The pattern of results held for all self-esteem measures except for the Collective Self-Esteem Scale (CSES). No differences between low and high self-esteem individuals were found when scores on the CSES defined self-esteem. These results may however be an artifact of interactions with social identity salience. Methodological shortcomings were found in the definition of low self-esteem. Individuals were most commonly classified as "low self-esteem" based on median splits of self-esteem scores. This strategy resulted in classification of some individuals as low self-esteem despite relatively high self-esteem scores. Results of the current analysis are interpreted as indicating that individual level phenomena such as self-esteem may be predictive of group level behaviors. Implications for social identity theories are discussed.
