Empirical Translation Studies have recently extended the scope of research to other forms of constrained and mediated communication, including bilingual communication, editing, and intralingual translation. Despite the diversity of factors accounted for so far, this new strand of research is yet to take the leap into intermodal comparisons. In this paper we look at Lexical Diversity (LD), which under different guises, has been studied both within Translation Studies (TS) and Second Language Acquisition (SLA). LD refers to the rate of word repetition, and vocabulary size and depth, and previous research indicates that translated and non-native language tends to be less lexically diverse. There is, however, no study that would investigate both varieties within a unified methodological framework. The study reported here looks at LD in spoken and written modes of constrained and non-constrained language. In a two-step analysis involving Exploratory Factor Analysis and linear mixed-effects regression models we find interpretations to be least lexically diverse and written non-constrained texts to be most diverse. Speeches delivered impromptu are less diverse than those read out loud and the non-constrained texts are more sensitive to such delivery-related differences than the constrained ones.

The article substantiates the methodological tools for the formation of the mechanism for implementing the strategy of sustainable economic development of the hotel and restaurant industry. To ensure the operation of the mechanism, a system of indicators and criteria for assessing the process of sustainable economic development, based on accelerating the growth of efficiency and reducing operating costs through reserve and progressive development of resource potential of the enterprise. The paper identifies the stages of sustainable economic development of the enterprise, which include: identification, grouping and analysis of factors of progressive and reserve development, their classification and determining the degree of influence on the growth of operational (production and administrative and marketing) activities, progressive development of resource potentials; development of regression models and indicators of progressive, reserve and sustainable (static and dynamic) economic development, which explain the patterns of influence of factors on performance indicators; forecasting the parameters of efficiency and cost of production and commercial activities; formation of the volume and structure of investments by types of capital investments that ensure the progressive development of resource potentials, economic growth and sustainability of the enterprise. A methodology for creating regression models and indicators was developed, which provided an opportunity to assess and predict the ratio of resource costs and the level of operational efficiency, as well as change the performance indicator by changing the values of factor parameters or their total value in different combinations. The algorithm of the organizational and economic mechanism of realization of strategy of management of steady economic development of the enterprise of hotel and restaurant sphere is constructed. This algorithm provided the ability to determine the reserves of available resources, as well as to establish the required size and structure of capital investments that reduce costs and increase the efficiency of production and administrative activities.
