SCIENTIFIC AND PEDAGOGICAL TEAM’S RECOGNITION DIAGNOSTICS BASED ON THE ANALYSIS OF THE RESEARCH ACTIVITY RESULTS

abstract 1541910016 issue 154 pp. 172 – 186 30.12.2019 ru 9
The research purpose is identification and justification of the scientific team’s recognition citation-based criteria. Such parameters of the educational environment as modality, latitude, social activity, social coherence, intensity, maturity etc. are assessable on the basis of the primary information about the scientific team’s research activity results. The authors of this article prove that the data about cross-citations within a scientific team is the primary information about the scientific and pedagogical team members’ recognition of their social system (such information is obtainable from modern scientometric databases, e.g. Russian Science Citation Index). The new scientific results of this research are the identified citation-based criteria for the scientific team’s recognition. The theoretical significance of these results is the possibility of using them as a scientific basis for further research in the sociology of science and for the development of the small social systems functioning models; the practical significance is the possibility to analyze the factors for the success of scientific and pedagogical teams’ research activity (i.e. applicability for the research activity monitoring systems). The research methods are: the methods of set, relations and graph theory, the methods of qualimetry, mathematical statistics (including the scree-plot method) and linear. The research methodology is based on the sociological approach (viewing the scientific and pedagogical team as a well-established social system), the qualimetric approach (declaring the necessity for the multicriterial diagnostics of scientific and pedagogical team’s recognition) and the probabilistic and statistical approach (viewing the scientific and pedagogical team’s recognition citation-based diagnostics as a statistic measurement)

SCREE PLOT METHOD AS A BASIS OF SOLVING METROLOGICAL TASKS IN SOCIAL AND HUMANITARIAN KNOWLEDGE FIELDS (ON THE EXAMPLE OF THE OBJECTIVES OF ECONOMICS, PEDAGOGICS AND SOCIOLOGY)

abstract 1291705099 issue 129 pp. 1371 – 1395 31.05.2017 ru 113
The article presents the main directions of the application of the scree plot method in solving metrological problems in the social and humanitarian fields of knowledge (economics, pedagogy, sociology, including sciencemetry). It is known that statistical measurements in socio-economic systems are inextricably linked with the processing of primary homogeneous monitoring information. It is also known that empirical averaging (computation of the empirical mean), as the dominant method of mathematical statistics, is becoming a thing of the past, due to moral aging, inconsistency with modern requirements (primarily to measurement results in socio-economic systems); In science meteorology, this method was replaced by the scree plot method (the Hirsch index and other scientometric indicators are estimated on the basis of this method). Despite its enormous potential, the scree plot method, as an alternative to traditional methods of mathematical statistics, is very poorly used in the social and humanitarian fields of knowledge. The authors of this article have shown that this method can be successfully applied in solving various metrological tasks, not only in science (sciencemetry is a branch of science), but also in economics, pedagogy and sociology. In addition, the authors show modifications of the scree plot method, using the example of measuring (measuring) indicators in the economy, sociology and pedagogy; The relationship between the scree plot method and the theory of latent variables (qualimetry) and database technology is grounded. The authors also substantiate that the scree plot method - the basis for the formation of monitoring indicators that adequately reflect the performance of socio-economic systems. The practical significance of the results of this study is that they can be used in socio-economic and psychological-pedagogical monitoring systems (according to modern views, monitoring is an information management mechanism). Methodological basis of the research: system, sociological, competence, probabilitystatistical and qualimetric approaches (leading methodological basis is the probabilistic-statistical approach). Research methods: modeling; Methods of graph theory, sets and relations; Systemic-cognitive analysis; Methods of qualimetry (the theory of latent variables); Methods of mathematical statistics

SOCIAL SCORING

abstract 0911307089 issue 91 pp. 1246 – 1263 30.09.2013 ru 1017
The new approach to the classification of the client by a method of credit scoring on the basis of the profiles of social networks is considered in the article. The approach illustrates interaction with social networks as new data source in credit process. Statistical methods of data processing and corresponding to them mathematical tools were involved in the analysis. The description of this approach is kept within the made experiment

SOFTWARE SYSTEM FOR ANALYSIS OF FLOW DIAGRAMS IN THE PRODUCTION OF AGRICULTURAL COMPANIES

abstract 1091505093 issue 109 pp. 1334 – 1354 29.05.2015 ru 625
The article describes a software complex which allows carrying out computer experiments in the study of economic efficiency of integrated production structures in agriculture and their stream of interaction. The article provides software used in complex mathematical ratios and their machine algorithms implementation. The authors have given a detailed description of the user interface with graphic examples. The application is written in programming language C#. This language was chosen for several reasons. The first reason is of course that C# is cross-platform that gives you the opportunity to use this app on any platform, and plays an important role in research activities. The final decision was influenced by the fact that in C# is implemented for working with charts, using standard library chart that provides a significant advantage compared to other programming languages during the development of the software complex
