We provide a formal account of an interface that bridges two different levels of dynamic processes manifested by mimicry: prey–prey interactions and predators' perception. Mimicry is a coevolutionary process between an animate selective agent and at least two similar organisms selected by agent's perception-driven actions. Attractor field model explains perceived similarity of forms by noting that in both human and animal cognition, morphologically intermediate forms are more likely to be perceived as belonging to rare rather than abundant forms. We formalize this model in terms of predators' perception space deformation using numerical simulations and argue that the probability of confusion between similar species creates pressure on the perception space, which in turn leads to inflation of regions of perception space with high density of species representations. Such inflation causes increased discrimination between species by a predator, which implies that adaptive mimicry could initially emerge more easily among atypical species because they do not need the same level of similarity to the model. We provide a theoretical instrument to conceptualize interdependence between objective measurable matrices and perceived matrices of the same external reality. We believe that our framework leads to a more precise understanding of the evolution of mimicry.

The objective of this review is to provide comprehensive, exhaustive and up- to-date information on the image and the distinctive features of the profession of a translator and its peculiarities due to the position of translators in society and their role as mediators between cultures. The number of intercultural contacts and the need for a precise understanding of the content of communication in today's global world is constantly increasing and under these conditions the importance of the professional activity of translators is significantly increasing. The article attempts to analyze the Erving Goffman's dramaturgical approach as a scientific paradigm for the analysis of professional translation. The article also discusses the notion of stigma and stigmatization as a communication mechanism. On the basis of the obtained data, it is possible to conclude that the negative attitude to a particular profession, the formation of a certain image of it which is associated with stereotypical perception, the isolation of social factors that contribute to the stigmatization of employment at different levels of communication today is of considerable research interest.

Innovations are significant source of competitive advantage for firms. They are also a major source of dynamics that forces firms to adapt their capabilities to sustain competitiveness. In this study we analyzed how firms manage their technological portfolio in mobile phone industry. Our first finding is that firms have focused differently their technology portfolios. Then we identified that most firms change their technology portfolio over time. And finally we conclude that firms in mobile phone industry have different levels of dynamics where some firms change their technology portfolio faster than others. This research identifies new challenges in dynamic capabilities research related to the appropriate level of dynamics in technology management. This information is crucial in practice in order to correctly manage the firm’s dynamic processes.

The article is striving to describe one of the genres of advertising discourse - the advertising of elite brand goods in Instagram - through the theory of speech genres. The study is based on the following principles of the theory: all communication phenomena can be described through their primary or secondary nature; any speech genre has a field structure. A field consists of a core represented by features opposing this genre to other genres, and periphery represented by shared features. Field features of a genre are represented by language units of different levels grouped around some invariant content which depends on the topic and aim of communication. We have built a field model of speech genre of advertising of elite brand goods in Instagram, where the core features are word-play, highly expressive vocabulary and allusions which all aim to create positive image of elite goods. The field periphery has been split into closer periphery (common for all e-advertising) and farther periphery (represented by features common for advertising in general). The features of closer periphery are instant, ubiquitous and interactive nature. The features of farther periphery are informative and evaluative character, inducement and creolized nature.

The article is devoted to the study of zoonyms functioning in the speech of the inhabitants of Troel’ga rural settlement, Kungur district (Perm Krai). Methodologically, animal names are considered in the article in line with the theory of derivation, that is, as a result of dynamic processes at different levels of the language system. It is necessary to distinguish between nicknames that appeared in the course of zoonymic transformations and those that appeared due to transformations of ready-made lexical means (products of pre-zoonymic transformations). We have found that the first ones form as a result of six types of derivation: word-forming derivation (with the formation of words that are absent in the literary language), lexical and word-forming derivation (with the formation of words that are homonymous to the words of the literary language), lexical derivation (with the use of non-derived words that are absent in the literary language: neologisms and barbarisms), lexical-semantic derivation (with the reinterpretation of the semantics of the generating word), lexical-grammatical derivation (with the functional transformation of the generating word), morphological derivation (with the grammatical transformation of the generating word). The words of the second group are included in the zoonymicon through lexical derivation (using derived and non-derived words of the literary language), lexical-semantic derivation (with semantic transformation of all-Russian words), morphological-syntactic derivation (with a change of the part of speech of all-Russian words). Within these types, certain derivational models are implemented, in particular k-suffixation, word convergence based on paronomasia, onymization and transonymization, substantivization, etc. The paper provides a conclusion about a variety of ways of forming modern zoonymicon, about the specificity of some particular derivational models for the given sample.

Abstract The stereotype of people with autism as unresponsive or uninterested in other people was prominent in the 1980s. However, this view of autism has steadily given way to recognition of important individual differences in the social-emotional development of affected people and a more precise understanding of the possible role social motivation has in their early development.

Abstract Hoerl & McCormack argue that animals cannot represent past situations and subsume animals’ memory-like representations within a model of the world. I suggest calling these memory-like representations as what they are without beating around the bush. I refer to them as event memories and explain how they are different from episodic memory and how they can guide action in animal cognition.

Recently we have been investigating a class of nickel-base superalloys which possess substantial room temperature ductility. This improvement in ductility is directly related to improvements in grain boundary strength due to increased boundary cohesion through control of detrimental impurities and improved boundary shear strength by controlled grain boundary micros true tures.For these investigations an experimental nickel-base superalloy was doped with different levels of sulphur impurity. The micros tructure after a heat treatment of 1360°C for 2 hr, 1200°C for 16 hr consists of coherent precipitates of γ’ Ni3(Al,X) in a nickel solid solution matrix.

Some authors using immunofluorescent techniques had already suggested that some hepatocytes are able to synthetize several plasma proteins. In vitro studies on normal cells or on cells issued of murine hepatomas raise the same conclusion. These works could be indications of an hepatocyte functionnal non-specialization, meanwhile the authors never give direct topographic proofs suitable with this hypothesis.The use of immunoenzymatic techniques after obtention of monospecific antisera had seemed to us useful to bring forward a better knowledge of this problem. We have studied three carrier proteins (transferrin = Tf, hemopexin = Hx, albumin = Alb) operating at different levels in iron metabolism by demonstrating and localizing the adult rat hepatocytes involved in their synthesis.Immunological, histological and ultrastructural methods have been described in a previous work.
