Human Associations Help to Detect Conventionalized Multiword Expressions

In this paper we show that if we want to obtain human evidence about conventionalization of some phrases, we should ask native speakers about associations they have to a given phrase and its component words. We have shown that if component words of a phrase have each other as frequent associations, then this phrase can be considered as conventionalized. Another type of conventionalized phrases can be revealed using two factors: low entropy of phrase associations and low intersection of component word and phrase associations. The association experiments were performed for the Russian language

A complete unitary similarity invariant for unicellular matrices

We present necessary and sufficient conditions for an n\times n complex matrix B to be unitarily similar to a fixed unicellular (i.e., indecomposable by similarity) n\times n complex matrix AComment: 16 page

Sources of income as a factor of interregional socio-economical differentiation of Russian population (1995 - 2007 YEARS)

The principal results of the statistical and econometrical studying of dynamics and factors of income inequality across the regions of The Russian Federation (RF) during 1995 - 2007 years have been presented at the paper. The objects of investigation have been the 79 subjects of RF. They have been described by variables: (a) population; (b) income per capita (at average for all population, living at the subject); (c) structure of income: the share of total income, obtained at average of all people in subjects, by five sources (their sum is equal to 100%): (1) business (enterprise) activity; (2) wages (salaries); (3) social transfers; (4) property; (5) other incomes. As the first step of "space - time" analysis dynamics and differentiation of seven named above indicators have been studied. The same initial indicators let us to estimate Total Monetary Income (TMI) and its five component TMI(k), k=1, . . .,5 for each from 79 regions of RF. The spatial distributions of new six variables and their evolution from beginning of transition up to crisis have been considered at the second step of investigation. The GINI and FUND coefficients have been calculated for TMI and for its five components. The subjects of TMI concentration have been determined by comparative level-dynamic analysis of these indicators. The same has been done for TMI(k) from five sources. It could say that practically each region of RF has had the different way of social - economic development. GINI decomposition by five sources of income, presented GINI as a linear combination of income structure and the Coefficients of Concentration, has been the next step of investigation. The results of decomposition indicated clear that two sources of income - (4) "properties" and (5) "other incomes" have been the main factors of interregional income inequality. There are "short lists" of subjects of RF, where the incomes from these two sources have been concentrated. The Decomposition method let us to discuss the different aspects of income inequality and make the emphasis at institutional factors of population economic activities and income redistribution

Expertise and Knowledge in the Age of Personalized Media: The Case of @anysports.faceonline Blog in the Period from 2018 to 2019

Digital age, that we are living in, enables us to instantly access great volumes of various information. The way we acquire, create and distribute knowledge is a subject to continuous transformation caused by the rapid growth of digital content and tools. Nowadays, more and more people give their own contribution in digital knowledge environment by producing and sharing their digital content. This thesis considers the impact that digital culture has put on the way we consume and create knowledge and establish the image of trustworthy expert in a certain field. This research is a case study of the Instagram account @anysports.faceonline. It represents a qualitative research aiming to analyze visual rhetoric and knowledge representation in the @anysports.faceonline blog in order to examine the mechanics of impression management, concerning the establishment and gaining acknowledgement of professionalism / expertise within online environment. By visual rhetoric is meant, in the first place, a form of visual communication the influencer uses. It involves the visual structure, displaying of information, color usage and designing of self-representation. Moreover, this research is not constrained in cultural history only, it refers to other fields such as psychology, sociology, marketing, media and gender studies. However, in order to explain the chosen visual strategies, the object of the research is, firstly, put into a broad cultural context

Electricity price volatility: its evolution and drivers

The Nordic electricity market offers an opportunity to study how intermittently available technologies are shaping up the future of the electricity markets. This work presents an empirical research on how the wind-produced energy affects the market and what challenges does wind power brings into it. The main proposition is that the wind power output makes the electricity prices less predictable and increases the allocative inefficiencies that already exist in the electricity market. In particular, the study is aimed at estimating the effect of wind power generation on the electricity price volatility in the Nordic electricity market. Additionally, the gap between the mean system price and the mean bidding area prices is described and analysed. Since most standard financial contracts traded in the Nordic countries use the system price as reference price, there is a need to investigate what factors affect the gap between the fictitious clearing price for the whole Nordic region and the actual electricity price at the moment of energy purchase. For conducting the empirical part of the analysis, the linear regression equations are constructed and used. The main objective of this thesis is to capture the wind power effect after controlling for seasonality, trend and exogenous supply shifters. This work also provides a starting point for discussions about the possibility of a new metering technology introduction (such as Smart Grid technology) to the Nordic electricity market

Improving cost management in the construction industry: a methodological aspect

This paper shows that the main task of developing a business related to construction is to obtain the necessary financial result with the condition of effective cost management. It is noted that among the existing means of optimizing costs, the main ones are considered effective planning, accounting and control, as well as a number of measures aimed at reducing costs. The aim of the study was to search for innovative approaches to the formation and maintenance of management accounting in the framework of cost management, and to develop a model of the information base for cost management in the construction industry. The study used comparative analysis, synthesis of theoretical and practical material, comprehensive analysis and systematic approach. The paper considers and analyzes the problems that hinder the building of a productive cost management system for construction production. A model of the information base for the cost management of a construction organization has been formed, which involves the application of calculation of complex cost items in the accounting system, with their subdivision in analytical accounting into fixed and variable. A detailed classification of production costs is proposed and justified singling out the components of cost of work related to construction and rationalizing costs. The main features of cost calculation and the possibility of their use in order to control the cost-price were investigated. Certain aspects of rationalizing cost management are formulated and a chart of accounts for the management accounting of a construction company related to rationalizing cost management is proposed. The relevance and importance of the issue under study for the use of effective ways, models and cost management schemes in the construction industry are aimed at increasing the significance and optimization of construction management. The considered system of analytical cost accounting for a construction company contributes to the most thorough analysis of operational data on costs, their structure and types, classification by construction objects, responsibility centers and places of formation
