The article deals with the current tendency towards an increase in Russian speakers’ verbalized metalinguistic reflection on language and culture contact, generated by growing exposure to global English and the influx of Anglicisms. Of crucial importance to cross-cultural research are metalinguistic commentaries, in which lay speakers register their negative attitude to those borrowings from English which reflect cultural norms and values clashing with the system of traditional Russian cultural norms and values. This is defined as a "linguacultural clash" or "linguacultural conflict"; its negatively marked metalinguistic interpretation is seen as part of speakers' "linguistic self-defense".
The paper discusses certain aspects of Indo-Uralic reconstruction, focusing on a comparison of our theoretical expectations from the comparison of Indo-European and Uralic basic lexicon with the actual results of lexicostatistical analysis.
Following pioneering ideas of Bojan Čop, this paper offers a brief sketch of a theory of the origin of Proto-Indo-European ablaut in the light of Indo-Uralic comparison. Starting from the assumption that Proto-Indo-Uralic phonotactics and morphophonology were essentially preserved in Proto-Uralic, but significantly changed in Proto-Indo-European, we trace the origin of Proto-Indo-European ablaut paradigms (mobile and acrostatic paradigms of root nouns, hysterokinetic, proterokinetic, amphikinetic and acrostatic paradigms of suffixed nouns). Each of these paradigms can be derived by a set of simple rules from the proposed Proto-Indo-Uralic reconstruction that is itself based on the conventional Proto-Uralic reconstruction.
In the paper, the classes of labile verbs (verbs which can be transitive or intransitive without any formal changes) are analyzed on the data of European and North Caucasian languages. The main conclusion is that there is a semantic difference between classes of labile verbs in the two language groups under analysis. In European languages, predicates with low semantic transitivity are labile (for instance, motion verbs and phasal verbs), while in Caucasian languages, lability is more characteristic of verbs with high semantic transitivity (verbs of destruction and similar verb classes).
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
The geographic information system (GIS) is based on the first and only Russian Imperial Census of 1897 and the First All-Union Census of the Soviet Union of 1926. The GIS features vector data (shapefiles) of allprovinces of the two states. For the 1897 census, there is information about linguistic, religious, and social estate groups. The part based on the 1926 census features nationality. Both shapefiles include information on gender, rural and urban population. The GIS allows for producing any necessary maps for individual studies of the period which require the administrative boundaries and demographic information.
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
