anthropology. Over the course of his career he created an original synthesis of research on the semiotics of communication, the sociology of interaction, Russian formalist literary theory, linguistic pragmatics, sociolinguistics, early anthropological linguistics and structuralist grammatical theory, together with his own theoretical contributions, yielding a comprehensive account of the semiotics of human communication and its relation to culture. His main influence was Charles Sanders Peirce, Ferdinand de Saussure, and Roman Jakobson. Current applications Some applications of semiotics include: Representation of a methodology for the analysis of "texts" regardless of the medium in which it is presented. For these purposes, "text" is any message preserved in a form whose existence is independent of both sender and receiver; By scholars and professional researchers as a method to interpret meanings behind symbols and how the meanings are created; Potential improvement of ergonomic design in situations where it is important to ensure that human beings are able to interact more effectively with their environments, whether it be on a large scale, as in architecture, or on a small scale, such as the configuration of instrumentation for human use; and Marketing: Epure, Eisenstat, and Dinu (2014) express that "semiotics allows for the practical distinction of persuasion from manipulation in marketing communication." Semiotics are used in marketing as a persuasive device to influence buyers to change their attitudes and behaviors in the market place. There are two ways that Epure, Eisenstat, and Dinu (2014), building on the works of Roland Barthes, state in which semiotics are used in marketing: Surface: signs are used to create personality for the product, creativity plays its foremost role at this level; Underlying: the concealed meaning of the text, imagery, sounds, etc. Semiotics can also be used to analyze advertising effectiveness and meaning. Cian (2020), for instance, analyzed a specific printed advertisement from two different semiotic points of view. He applied the interpretative instruments provided by the Barthes' school of thinking (focused on the description of explicit signs taken in isolation). He then analyzed the same advertising using Greimas' structural semiotics (where a sign has meaning only when it is interpreted as part of a system). In some countries, the role of semiotics is limited to literary criticism and an appreciation of audio and visual media. This narrow focus may inhibit a more general study of the social and political forces shaping how different media are used and their dynamic status
