Annotation: The article deals with approaches and interpretations of intercultural communication in XX works. It is the epoch when the latter started branching out as an independent sphere of knowledge under accelerating informational and globalization processes, which led to increasing intercultural contacts. It reviews the theories of G. Hofstede, E. Hirsch and E. Hall. Particularly important is interconnection of intercultural communication and intercultural competence that is revealed basing on aforementioned ideas.

Annotation: The article reveals psychological and pedagogical aspects of intercultural communication as knowledge. Particular attention is paid to their interconnection in the context of issues of forming personality in contemporary multi-ethnic society. It also reveals intercultural communication influencing theory and practice of teaching foreign languages. Intercultural communication is presented as a paradigm of this process that touches on its theoretical basis and practical aspects.

Annotation: The article provides comparative analysis of Russian and Bulgarian languages for differences in alphabet, lexis and grammar. The author estimates correlation between Bulgarian language aspects and their Russian analogues. The conclusion is that despite visible similarity Bulgarian language structure is considerably different from Russian. As a result there is considerable language interference in the process of learning it.

The information message model is considered as a complex model in which different information models change their shape while maintaining the content.

Annotation: The article analyzes two types of information. The first kind of information is related to entropy and the work of K. E. Shannon. This information reduces uncertainty. The second type of information is associated with negentropy and the works of N. Winner and L. Floridi. The article describes the difference between the concepts of “ignorance” and “knowledge”. Paper describes an example showing the difference between the amount of information for KE Shannon and N. Winner. The article describes a method for estimating negentropy based on “non-Gaussian”.

Annotation: The article describes a new approach to the information situation model. The article describes the types of information situations. The article analyzes structural models of complex systems. The article analyzes structural models of information situations. Paper shows the similarity and difference between structural models of a complex system and information situation. Paper compares models of information situations and models of complex systems. Paper concludes that it is possible to use a model of a complex system to describe the information situation. Paper concludes that it is possible to apply the theory of systems to study the information situation model.

Annotation: The process of formation and transformation of dominant emissions in the case of energy generation – carbon dioxide (CO2) is considered. The effect of CO2 on climatic thermal vibrations is shown. The use of anthropogenic CO2 emissions as a tool for market manipulation is disclosed. The irrelevance of the reduction of anthropogenic CO2 emissions in the Russian Federation is shown. The proposal to collect payments of «carbon rent» from the emitter countries is substantiated.
