The concept of speech act "request for decision making" in forensic discourse analysis for investigation of crimes committed by organized crime groups

The article focuses on discourse in crime organizations and emphasizes the complexity and diversity of communication in modern corporate crime groups. Research methods of forensic linguistics in this area must be focused on the identification of: a) a concept of joint activity of a crime group; b) speech features of group communication in an organization; c) speech features of a status hierarchical situation, functions and roles of participants within intra-group communication. Correspondence between an organizational structure and discourse is seen here as a two-way relationship. Creating texts (written, spoken and computer-mediated) forms an important part of an organization's work. Texts are influenced by the social context, thus reflecting the organization and its social structure, values, knowledge and culture. But texts also play a role in establishing various social dimensions of the organization. In close-knit workplace groups there is an obvious connection between the social and the communicative plane too. The group structure is reflected in the communicative organization: the hierarchical social structure is reflected in communicative patterns relating to influence and supervision. Discourse reflects social organizational patterns and also plays part in the construction of the 'organizational self , in the shaping of the organization. This article describes the concept and the structure of speech act "Request for Decision Making" in forensic linguistics research. The explication of this speech act is used for analysis of roles and status as interaction competencies in organizational discourse. Procedure of speech act detection is offered as a prospective operational research method of modeling the hierarchy configuration of a communicative network founded on the information streams and decision-making functions. It helps distinguish the basic traits of discourse in varied forms of the organization. Though many traditional linguistic indicators of intra-group communication are not informative for organizational discourse, with a theoretical orientation towards sociolin-guistics, discourse analysis, speech act theory, organizational linguistics and organization network theory, these researchers have sketched the frames which influence discourse at various levels within organizations. This approach is determined by law enforcement officials' need for expert studying of status hierarchy, roles and functions of crime group members to help prove their fault.
