This chapter describes basic approaches to the study of socio-psychological climate of the organization and its structural components and the formation factors, discussed problems of diagnosis of socio-psychological climate and its relationship to job satisfaction and efficiency of joint activities. General description of the conflicts in the organization, their typology and the main methods of conflict resolution are presented.
The results of psychometric validation of a model of in-group identification (Leach et al., 2008) in three Russian samples are presented. The theoretical model is hierarchically structured. It includes five components (individual self-stereotyping, in-group homogeneity, in-group solidarity, satisfaction with in-group, and centrality of in-group identity) that form two second order factors (self-definition and self-investment). The samples included members of a social group («students», N = 196), an ethnic group («Russians», N = 146), and a religious group («Orthodox Christians», N = 249). In study 1 different measurement models were compared for each sample using confirmatory factor analysis. The results support the hierarchical model with two second-order factors. The sets of items comprising each of the five in-group identification components have high internal consistency and discriminant validity. Study 2 focused on the validity of the new instrument in the ethnic group subsample using a number of Russian-language ethnic identity measures. The data indicate convergent validity of the new measure, indicating that its five scales tap into cognitive, affective, and behavioral components of identity with an ethnic group. The results of two studies show that the new Russian-language instrument based on the model of in-group identification has convergent and discriminant validity. Limitations of the study and future directions for the development of the instrument are discussed.
This chapter provides an overview of the group in the organization, its structural components, group defense mechanisms are mentioned, through the process of building a team, intergroup interaction in the organization are revealed.
The textbook contains necessary information about universal and classical algebras, systems of axioms for the basic algebraic structures (groupoid, monoid, semi-groups, groups, partial orders, rings, fields). The basic cryptographic algorithms are described. Error-correcting codes - linear, cyclic, BCH are considered. Algorithms for designing of such codes are given. Many examples are shown. It is put in a basis of the book long-term experience of teaching by authors the discipline «Discrete mathematics» at the business informatics faculty, at the computer science faculty of National research university Higher school of economics, and at the automatics and computer technique faculty of National research university Moscow power engineering institute. The book is intended for the students of a bachelor degree, trained at the computer science faculties in the directions 09.03.01 Informatics and computational technique, 09.03.02 Informational systems and technologies, 09.03.03 Applied informatics, 09.03.04 Software Engineering, and also for IT experts and developers of software products.
