dc.description.abstract

value:
Purpose: to systematize the development strategies of private multi-field clinics under the
new geopolitical conditions in Russia and to analyze the impact of sanctions policies on them,
and to identify directions for leveling it out. Methodology: The Ansoff method, content
analysis, statistical, analytical, and abstract-logical methods were used to systematize the
development strategies of Russian private multi-field clinics. The information base for the
study consisted of regulatory legal acts in the field of medical services, annual reports of
medical clinics and analytical agencies, data from the Federal State Statistics Service of the
Russian Federation, the materials from the associations of private clinics. Findings: the
practice of levelling out the sanctions pressure on the Russian economy in the healthcare
sector is generalized and the development strategies of private clinics under the new geopolitical
conditions in Russia are systematized using the Ansoff model. Originality and contribution:
the study is the first attempt to systematize the development strategies of private multi-field
clinics in the context of sanctions pressure on the Russian economy and to generalize the
practice of levelling out the negative impact of sanctions on the private healthcare sector.
The findings of the study are relevant for both academic researchers from the commercial
healthcare and for managers of private Russian clinics.

dc.description.abstract

value:
Background and Aims: In the roots of most vascular plants, the growth zone is small, the meristem and the elongation zone are sharply separated, and only meristematic cells divide. This statement is based almost entirely on studies with soil-rooted plants. Whether aerial roots of structurally dependent (=epiphytic/hemiepiphytic) species differ is virtually unexplored.

Methods: Growth of aerial roots in 20 structurally dependent plant species from eight families was studied ex situ. In 12 species, we studied the anatomical structure and distribution of cortex cell lengths and rhizoderm in the growth zone.

Key Results: All the studied aerial roots had an open apical meristem, and mitoses were not restricted to the meristem. In contrast to belowground roots, relative growth rate did not strongly increase upon transition to the elongation zone, while elongating growth was often prolonged. Still, the relative growth rate was lower than in belowground roots in soil, and in different species, it did not change considerably compared to each other.

Conclusions: A distinct elongation zone with rapid cell growth was missing in the studied aerial roots. Rather, there was a growth zone in which division, growth, and differentiation co-occurred. We observed a generally low relative growth rate in aerial roots and a surprisingly similar initial growth pattern in spite of the diversity in taxonomy and ecology, which resembled initial cellular growth in leaves, stems, and fleshy dicotyledonous fruit.

value: We propose the generalized multipomeron exchange model for multiparticle production in high-energy proton–proton, proton–nucleus and heavy-ion collisions. For all of these systems, we consider collectivity effects based on the quark–gluon string fusion concept, where new types of particle-emitting sources—strings with higher tension—are produced. We obtained the model parameters using the data on the multiplicity dependence of the mean transverse momentum of charged particles in pp and pp¯ collisions over a wide energy range (from ISR to LHC). We calculated the yields of strange, multi-strange and charm particles as a function of multiplicity for pp, p-Pb and Pb-Pb collisions at the LHC energy and compared the results with the experimental data.

title: SOME ACCENTUATION OPTIONS FOR NON-DERIVATIVE FEMININE NOUNS WITH STEM ENDING WITH -А (-YA)

dc.contributor.author

value: Antonova, Olga V.

dc.description.abstract

value:
One of the unstable links in the field of nominal stress is accentuation of non-derivative
feminine nouns with a stem ending with -а (-ya). It is well-known that during the
development of the literary language, the place of stress in these lexemes gradually
changed. In particular, there is a transition in subparadigm of the plural from flexion
stress to root stress, as a result an additional opposition of numerical subparadigms is
formed. Such changes are associated with the tendency of grammaticalization marked
by V. N. Sidorov: singular and plural nouns strive for opposition on the basis of accent
(old accent paradigms unite, and the stress in them is unified in singular and plural
forms). To clarify the features of modern accent processes and clarify orthoepic recommendations
we conducted an experiment. The results of the experiment, on the
one hand, confirmed the tendency noted by V. N. Sidorov, and on the other hand, have
shown nouns that do not follow this pattern and keep the old stress, as well as word
forms, the stress in which changes differently. Accentuation dynamics are not always
adequately reflected in modern spelling dictionaries: the results of the experiment
clearly demonstrate that for a number of names, codification decisions should be adjusted.
It is obvious that it is not the class of words that requires close attention, but
each individual word (and sometimes even a word form). Refs 20.

dc.description.abstract

value:
According to L. A. Verbitskaya, the norm is “a set of phenomena allowed by the language
system, selected and fixed in the speech of native speakers and mandatory for
all who speak the literary language at a certain period of time”. The norm is static, it
makes the literary language understandable for everyone and at any time. Researchers,
however, noticed that the norm is a constant only with a great deal of convention.
The codified norm is opposed by the real “norm–usus”, which is well understood by
native speakers, but hasn’t been recorded almost anywhere. A good exception are the
reduced forms (RF) of Russian super–frequency words. According to the compilers, RF
is not just speech errors of people in a hurry, but the result of the evolutionary development
of the language. Many of them can already be qualified as the norm of
colloquial speech. The dictionary contains the most complete information about each
form: from the written appearance of the original unit to real transcription based on
auditory and instrumental analysis of contexts from the corpus of Russian everyday
speech. This dictionary has a specific potential user: teachers of Russian as a foreign
language (RFL) and foreign students. They hear these forms in our speech, see them in
written texts — in the speech of literary characters — and don’t know how to use them
and even often — how to understand them. The dictionary offers a compact list of such
forms (100 units), with examples, simplified transcription and frequency lists, which
makes it virtually a ready–made manual for RFL. Refs 22.

title: JOHANN SEVERIN VATER AND SAMOYEDS

dc.contributor.author

value: Klubkova, Tat’iana V.

dc.description.abstract

value:
The purpose of the article is to show the process of formatting a new kind of linguistics,
a contribution by A. Schlözer and I. S. Vater of their version of modern linguistics
based on the Samoyed (Nenets) language research. The article demonstrates the way
the researchers have arrived at their conclusions through careful selection of sources, both published and archived. The 18th century, the “age of systematics”, complete with
a new division of sciences, arrived at the transformation of ethnography and linguistics
into independent disciplines. Those were prerequisites for the emergence of comparative-
historical linguistics. Using the Samoyed language studies as an example, the article
examines Schlözer and Vater’s solution of the problems arising in identifying linguistic
kinship: the lack of grammatical descriptions and the difficulties of reliable fixation
of a non-written language. The works by Vater are the most significant precursors for
the first grammar of the Samoyed language, i. e. The Samoyed Grammar by M. Castrén
(1854). Schlözer insisted that the Samoyeds were an independent people, and that the
section of his Northern History devoted to their community was a traditional comprehensive
description of history, geography, customs, and language. The author determines
the place of the Samoyed language among the neighboring peoples, critically analyzing
the sources while offering a thematic Latin-Samoyed dictionary. Schlözer’s materials
were later referred to in the Comparative Dictionaries… by P. S. Pallas. I. S. Vater, realizing
the need for a new classification of sciences, headed the department of ethnography
and linguistics, thus re-defining the object of linguistics. Regularly addressing the
Samoyed language, as well as publishing texts, dictionaries and grammar notes in it,
both addressing his informants and actively cooperating with the international academic
community, Vater placed the Samoyed language into a rich academic context.
The activities of the conscientious and impartial authors in their particular academic
field demonstrates a long process of introducing their new information into circulation,
together with changes of visual description: from a mixed description (by Schlözer) to
the distinction between ethnography and linguistics (Vater). Refs 12.

dc.description.abstract

value:
The article discusses the development of the lexicographic codification of pronunciation
norms of German. It gives an overview of the orthoepic norm, its varieties and inherent
features, relations between the norm and standard of pronunciation. Pronouncing dictionaries
since the end of the 19th century have been studied as primary sources, some
phonetic phenomena are also illustrated with the explanatory dictionaries of earlier
periods. The lexicographic codification of the pronunciation norms in historical retrospect
is briefly analyzed: from exaggerated articulation of actors in Germany to actual
sound phenomena using in the pronunciation of professional radio and television announcers,
which includes the pronouncing features of authentic oral media communication.
Special attention is paid to the problem of codification of the orthoepic standard
in different types of dictionaries in light of the pluricentricity of German, due to lack
of empirical analyses. The article also represents the current orthoepic dictionaries,
which include information about the sounds of three standards of German in Germany,
Austria and Switzerland. Study of their structure and content features made it possible
to identify some advantages and disadvantages. As a result of the study, the author
concludes with changing approaches to the codification of pronunciation norms, such
as transformation of the metalanguage, expansion of the empirical base, use of contemporary
sociophonetic methods in its analysis, some structural and content changes
in the dictionaries. These modifications are shown to be connected with the change of
the lexicographic paradigm and the turn from monocentricity to pluricentricity due to
sociocultural and sociolinguistic factors. Refs 24.

title: TESTIMONIAL EVIDENTIALITY AT EXPRESSING EMOTIONAL-EVALUATIVE INTENSION IN TIBETAN

dc.contributor.author

value: Kramskova, Anna S.

dc.description.abstract

value:
Modern Tibetan has a paradigm of evidential verb forms, with the help of which the
speaker indicates the source of information or their access to it. The semantically
marked testimonial evidentiality (which corresponds to sensory sources of information
about the fact of the utterance) can be used by the speaker to implement various communicative
intensions, in particular, emotional-evaluative intension. This article presents
the results of a study of speaker’s expression of emotional-evaluative intension
using the forms of testimonial evidentiality in Modern Literary Tibetan. The relevance
of the work is based on the insufficient study of how Tibetan speakers express communicative
intensions and how evidentiality is implemented in written Modern Tibetan.
The analysis was carried out on a morphosyntactically marked corpus of 83,018 tokens
combining 20 texts of various genres of fiction, academic and journalistic writing in
Modern Tibetan. A speaker was understood as any addresser of an utterance in direct
speech and first person narration parts of the text (author, literary character, lyrical
subject). For the selection and analysis of utterances with an emotional-evaluative intension,
contextual analysis was used, characterizing the addresser, addressee and the
object of the utterance, speech situation, as well as the meaning of the verb form in
the scope of the operational context. The analysis showed that when expressing emotional-
evaluative intension with the help of testimonial evidentiality, the speaker emphasizes
one of the aspects of the meaning of this type of evidentiality: 1) objective or
perceptual lack of control over the observed action or situation by the speaker; 2) direct
evidence of the fact of the utterance as a source for an unaddressed emotional state;
3) direct observation of the speaker as an evidence for assessing and validating the reliability
of the reported fact. The article provides information on the evidential system
of the Tibetan language and the most common communicative intensions formalized
by testimonial evidentiality, as well as discusses in detail individual cases of expressing
emotional-evaluative intension along with the analysis of the speaker’s communicative
position and his choice of means of expression. Refs 22.

title: AN EXPERIMENTAL STUDY OF THE EFFECT OF SYNTACTIC COMPLEXITY ON THE REALIZATION OF SENTENTIAL COMPLEMENTS IN RUSSIAN

dc.contributor.author

value: Knyazev, Mikhail Yu.

dc.description.abstract

value:
Declarative sentential complements in Russian can be realized either directly as čto-clauses
or as čto-clauses embedded in the nominal construction headed by the “correlative”
pronoun to. In previous studies, several factors that influence the choice of one of these
two strategies have been identified, including the discourse status of the complement,
the agentivity of the verb, the choice of the verb, register, etc. This study investigates the
effect of syntactic complexity of the sententce in which the complement clause is embedded.
The effect of complexity has been demonstrated before on the basis of several corpus
studies of various constructions in English, which suggested that higher complexity
is associated with the preference for the more explicit construction in the case of alternations.
The goal of this study was to test whether complexity leads to a higher preference
for the construction with the correlative (being the more explicit of the two alternants).
Complexity was operationalized as additional embedding of the complement-taking
predicate in a relative clause, either with a finite or a participial head (the latter presumably
leading to still higher complexity). The hypothesis regarding the effect of complexity
was tested in two experiments, an acceptability judgment study and a (100-scale) graded
forced choice study. The experiments also tested the effect of the association between a
verb and one of the two complementation strategies in the corpus (using the Attraction
measure) as well as the effect of the subcategorization frame of the verb, i. e. whether it
can take a direct object (by hypothesis, leading to the higher preference for čto-clauses)
or only an oblique. The results of the experiments did not show an effect of complexity,
which might be due to a small size of the effect and/or the nature of the task. However,
the experiments revealed the effect of the Attraction class and of the subcategorization
frame, namely, in oblique positions sentential complements show a higher preference
for the correlative as opposed to direct positions. At the same time, verbs that have a
higher association with čto-clauses in the corpus, show an approximately equal preference
for both strategies. An explantion of this effect is proposed. Refs 16.

dc.description.abstract

value:
M. Lomonosov’s texts in German provide numerous examples of word spelling inconsistency,
e. g. Freiheit/Freyheit, Dero/dero, etc. The influencing factors for this are Lomonosov’s
individual style and the scientific and educational discourse of 18th century Russia.
The research focuses on the alternation of g/h and g/сh. The alternation at the beginning
of a morpheme (Staffengagen/Staffenhagen) can be explained by the similarity in the pronunciation
of the German letters g and h in Russian educational tradition. As possible reasons for the alternation in the intervocal position after i (abziegen/abzihen) and ei (verzeigen/
Verzeigung/verzeihen), one can point at voicing of a voiceless consonant /h/ in the
position between two vowels and Russian spiranta /ɤ/ functioning as a variant of the
phoneme /g/. In the final position of a word, the alternation of g / ch is observed in adjectives
with the suffix -lich, causing a deviation from the standard spelling in the words
neulig and unmöglig. In this case, the explanation could lie in the fact that in the German
language, two productive derivational suffixes -ig and -lich exist, similar in form and in
semantics. Also in the German texts of Lomonosov one can find variants Petersburg/Petersburch
with alternating g/сh at the end of a word. The tradition of substituting -urch for
-urg in place names survives in Russian grammar textbooks for foreigners up to mid–19th
century as Russian г is pronounced as /x/ at the end of some words. Refs 22.

title: PRONUNCIATION NORMS THROUGH THE EYES OF A LEXICOGRAPHER

dc.contributor.author

value: Kalenchuk, Maria L.

dc.description.abstract

value:
One of the most controversial issues of orthoepy is the criteria for making codification
decisions in the case of coexistence of pronunciation variants. For the authors
of dictionaries, this question is especially important, since its solution determines the
logic and procedure for the transition from pronunciation in the sounding speech
of educated people to a codified norm. There are two approaches that determine
the decision-making algorithm for the transition from pronunciation in live speech to
codification recommendations — subjective and objective. A subjective assessment
of the facts of orthoepic variability is called the position of an unconditional idea of
the normativity of a variant based on tradition, following authoritative samples and
the personal taste of the author of recommendations. An objective assessment of
orthoepic variants can only be the result of representative sociolinguistic studies of
the usus, which were started on the material of the Russian language in the 1960s
under the leadership of M. V. Panov. The definition of the methodology is inextricably
linked with the question of choosing criteria for recommending one of the coexisting
pronunciation variants as a codified norm. The article discusses various reasons
for making a decision to recommend a specific pronunciation variant as the norm:
1) compliance with the internal language law; 2) compliance with the cultural and
historical tradition; 3) the prevalence of the variant and the statistics of the norm;
4) public approval and recognition by society of the variant as normative. It seems
that the pronunciation variants identified in the sounding speech of educated people
during representative and systematic sociolinguistic studies should be taken into
account when developing pronouncing recommendations. And the only argument
that prevents the usual variant from being given the status of a codified one is a violation
of intra-linguistic laws. All other criteria — cultural and historical tradition, the
authority of experts, speech skills and language taste of the author of the dictionary,
etc. have a secondary character. Refs 16.

value:
The article analyzes two prominent researches of the 1920–30th (World revolutionary
propaganda by H. D. Lasswell and D. Blumenstock and The Language of the Red Army
Soldier by I. N. Shpil’rein et al.) and proposes an attempt to look at certain aspects of Soviet
science, particularly at the study of linguistic mechanisms of propaganda, not within
the framework of a revisionist approach, but including it in the broader scientific and
cultural and historical context. The analysis focuses on basically linguistic approaches
used by the psychologists, sociologists, and political scientists of the USSR and the USA. The choice of these researches is conditioned, on the one hand, by the mutual interest
of the two countries, on the other hand, by the fact that the problem of studying propaganda
as a way of spreading communist ideas was equally acute for both countries,
albeit with mirror-opposite goals underlying this interest. The analysis of the selected
studies demonstrates similarities in study design and methodology. Refs 22.

title: MORPHONOLOGICAL PROPERTIES OF NOUNS WITH -KA ELEMENT IN THE FINAL PART

dc.contributor.author

value: Voeikova, Maria D.

dc.description.abstract

value:
Nouns containing -ka in their final part have some distinct common properties: they
have homogeneous and salient inflectional endings and belong to most frequent
(1st and 2nd) declension classes, they are mostly built with several productive derivation
patterns and therefore, gain in type and token frequency. This paper addresses some
other, not so obvious particularities of this morphonological group. Their accentual
types in several case forms tend to be connected with certain semantic groups (e. g.,
four syllabic masculine nouns in the genitive mostly denote masculine nouns meaning
occupation: ljubovnika ‘lover-Gen’, nachal’nika ‘chief-Gen’), thus, helping to disambiguate
the usual case syncretism. The data is taken from the frequency lists of word forms
of the Corpus of Russian literary language. Accentual types were defined by the number
of syllables and by the stress placement. The observations are interpreted from
the point of view of systemic approach to modern Russian grammar including the further
elaboration of bootstrapping mechanisms that are usually in play during speech
perception by adults and language acquisition by children. In this case we deal with
the morphonological bootstrapping determining the hidden preferences of speakers.
These observations serve as a base for future experimental study of this and similar
morphonological groups that should be taken into consideration during the analysis of
productive derivation patterns and their structural functions, the correlation of semantic,
pragmatic and structure, as well as their perceptive capacities. The prediction for
experimental study is that nouns with -ka in the final part should be earlier recognized
in the reaction time experiments, easier processed and, probably, earlier acquired by
children. Another development of this topic is a similar description of the final -k- of the
stem followed by other vowels marking oblique cases, like e, u, i and o, that, however,
would be not as promising because of poorer syncretism in the sphere of other inflectional
endings. Refs 20.

The article is devoted to the works of L. A. Verbitskaya in the field of the Russian standard
pronunciation, manifestations of the orthoepic norm in different conditions of the
speaker’s speech activity. Research carried out at the Department of Phonetics of St Petersburg
State University in recent years and continuing at the present time shows
which phonemic sequences, differing from those prescribed by orthoepic dictionaries,
are observed in the speech of both professional speakers of the pronunciation norm,
and in the speech of young people in careful and reduced speech. The analysis of the
obtained results leads to possible interpretations of the terms “careful and reduced
pronunciation types”, “careful and reduced (colloquial) styles” of pronunciation. The
article also provides new data on the tendencies of change in the phonological system of the Russian language, formulated by L. A. Verbitskaya, which can lead to a change in
the pronunciation norm. A previously developed automatic transcriber is described. It
converts the text into a sequence of phonetic symbols that meet the requirements of
the orthoepic norm, and also offers variants of deviations from the norm observed in
a large corpus of prepared professional speech, as well as the statistical probabilities
of these deviations. The issues of both the loss of labialization, repeatedly described
by L. A. Verbitskaya, and abnormal labialization, are also considered, to be taken into
account in the new version of the automatic transcriber. Refs 35.

title: ORTHOEPY — HISTORY OF LINGUISTICS — HISTORY OF LANGUAGE

dc.contributor.author

value: Kleiner, Yuri

dc.description.abstract

value:
The definition of orthoepy as “a branch of linguistics that studies pronunciation norms”
tends to determine the understanding of its tasks as exclusively prescriptive, and that
of orthoepy as a whole as an applied area, par excellence. Its other component, purely
linguistic, is present in the problem of the correlation between the system and the
norm, traditionally central to the school of Lev Shcherba. In essence, this problem
is a particular case of the Saussurian “language — speech” dichotomy, which is the
reason for regarding orthoepy as a purely linguistic discipline and for discerning two
points of view on its object, those “from within” and “from without.” The latter implies
a conscious attitude towards the choice, from several possibilities, of one unit as a
normative or “correct” with the establishment of the systemic status of this unit. This
point of view on language, which emerged almost simultaneously with the awareness
of it as an inherently human capacity (Plato), is reflected both in the early evidence
of “language prestige” (Catullus, Cicero) and in the works of “intuitive linguists,”
either relying on a certain norm (Alexandrian grammarians) or creating it (English
orthoepists). In turn, the norm is synonymous to speech, which exists at a given
synchronic stage; it changes either as a result of the alternative possibilities offered
by the system (language dynamics) or due to the transition of the system to another
synchronic stage (linguistic change per se), cf. Ludmila Verbitskaya’s formulation in The
Linguistic Encyclopedic Dictionary: “The phonological system of a language completely
determines the pronunciation norm. The norm can change within the system provided
new forms gradually replace the old ones under the influence of extralinguistic factors
or as a result of changes that have taken place in the system.” In this context, the
primary task of interpreters of early orthoepic evidence (first of all, historians of language)
is to identify factors belonging to two fundamentally different spheres. Ignoring
this circumstance in the research procedures, characteristic of (chronologically or
ideologically) pre–Saussurian (pre–Baudouin de Courtenay) linguistics, leads to a confusion
of factors, including systemic and extra–linguistic ones, and, moreover, of the
fundamental notions, (diachronic) change and (synchronic) variation, which, among
other things, is reflected in the idea of ‘recent changes’ in the system (in fact, in the
norm) and in the popular notion of “language in the state of (constant) flux.” On the
contrary, the consistent differentiation, in research procedures, of different factors interacting
in the functioning of language system, and thus discerning between the two
points of view on it, “from within” and “from without,” makes orthoepy an integral part
of linguistics as a fundamental science of language, providing theoretical justification
for its applied component, the latter’s goals having been formulated, for all times, as
a maxime to “speak properly and correctly.” Refs 29.

dc.description.abstract

value:
The article presents the results of the analysis of the functions of interrogative sentences
in modern experimental (fragmented) fiction, that reflects the processes of disintegration,
based on the works of small prose (about 5 % of all short story texts) published
in the magazines “Znamya”, “Octyabr’” and “Novyj mir” in the last 5 years. The selection
of the material is based on the author’s definition of the narrative genre (short story,
small prose, other prose, prose), on the formed discreteness of the text (various
types of rubrication at the level of macro-syntax, at the level of microsyntax — the
dismemberment of the syntagmatic chain of the sentence, the elimination of connectivity
indicators, the use of alternative punctuation), on the identification of non-standard
metagraphemics as the design piece of art’s means. A comprehensive analysis of
the disintegration degree of small volume texts with interrogative sentences (question
marks), pragmatics (types of questions), structural features (single questions, chains of
interrogative sentences, combination with parcellation), the context of the introduction
(position in the structure of the text and the presence/absence of a direct answer in
a question-and-answer situation) allows you to determine the following functions of
interrogative sentences in the text of experimental prose of small form 1) complication
of the subject perspective of the text by removing the traditional punctuation of the
parties of speakers in dialogues and including private questions in them; 2) metalanguage
narrator’s reflection performing in the text with the help of existential rhetorical
questions and unanswered questions; 3) the performance of the text-forming function
of interrogative sentences in lyric monologues reflecting auto-communication. The revealed
features of questions in modern prose reflect the author’s search for a means
of compensation for disintegration, the increasing colloquialism of a literary text and
the change in the recipient’s perception of his narrative (the desire to remove distance,
modeling online communication), which is predetermined by the orientation to the
modern reader, the search for new forms of artistic communication. Refs 18.

At the beginning of the 20th century, the French Antoine Meillet (1866–1936) and the Soviet
Nikolaj Yakovlevich Marr (1864–1934) were probably the most prominent linguists
in their respective “worlds”: Meillet, in Western Europe, as the chief of the Indo-European
comparative linguistics, and, in the Soviet Union, Marr as the herald of the so-called
Marxist Soviet linguistics. These two approaches generally considered antagonistic, but
that did not prevent Marr and Meillet from maintaining contacts, corresponding with
each other for many years and knowing about their respective research. First, this paper
aims to present the contacts these two linguists had, focusing on the correspondence
between Meillet and Marr. Secondly, the paper examines what Meillet thought
about Marr and his theories, on the basis, in particular, of the numerous reviews that
Meillet wrote about Marr’s works. Refs 11.

dc.description.abstract

value:
Although the corpus of poetic inscriptions in younger runes has in the main been established
in early Scandinavian scholarship, the structure and formulaic character of inscriptions
have not yet been subjected to detailed research. In the paper, the structure
of poetic runic texts has been described in the light of the hypothesis of the isochrony
of bars, admitting an occasional lengthening of short syllables and shortening of long
syllables. The formulaic structure is most clearly seen in the younger runic inscriptions
on memorial stones. The formula is based on a constant alliterating pair (cf., for example,
standa ‘to stand’ — steinn ‘stone’), whose elements occupy different short lines, cf.
Hēr mun standa / steinn nær brautu ‘Here will stand a stone by the road.’ The varyable
parts of the formula occupy the beginning of the first short line and the end of the
second short one. Hēr mun can be replaced by prosodically equivalent and semantically
similar combinations Nū skal, Hēr skal, Æ mun, and nær brautu ‘by the road’ can
be replaced by the prosodically equivalent and semantically similar viðr bryggju ‘by the
bridge’, ą bjargi ‘on the mountain’, miþli byja ’between villages’, at merki ‘as a monument’,
at Ingjald ‘after Ingvald’. The paper also addreses some other most common
formulas based on alliterating pairs. Refs 24.

title: INTERROGATIVE PRONOUNS CHTO ‘WHAT’, KTO ‘WHO’, KAKOI ‘WHICH’ AND LINES OF THEIR DERIVATIVES IN THE L1 ACQUISITION

dc.contributor.author

value: Krasnoshchekova, Sofia V.

dc.description.abstract

value:
The article examines the acquisition of pronouns of the lines kto ‘who’, chto ‘what’ and
kakoi ‘which’, belonging to the interrogative, indefinite and negative groups, by Russian-
speaking children. We have used longitudinal data, those being recordings of the
speech of 5 children aged from 2 to 4 years. Analysis of the functional-semantic and
morphological-syntactic features of pronouns in the speech of children allowed us to
draw the following conclusions: children’s speed and ease of mastering the pronouns
depends not only on their frequency in the input, but also on the internal linguistic
features of each lexeme. The role is played by the combination of the function of a
pronoun in a specific utterance, and the basic meaning of the series: for example, in the
chto ‘what’ line such cognitively successful combination is “concreteness + objectivity”,
and in the kto ‘who’ line “animacy” refers to the lesser level of “concreteness” (this may
be explained by the later appearance of lexemes of this line in children’s speech). The
line of kakoi ‘which’ demonstrates association between the attributive meaning and a)
pure indefiniteness (including non-concreteness in irrealis) and b) deicticity, when primarily
non-deictic interrogative kakoi ‘which’ and indefinite kakoi-to ‘some’ in the speech
of children in relative-demonstrative, emphatic, and actualizing contexts approach the
demonstrative takoi ‘such’. The development of the morphological and syntactic side
of pronouns occurs in children without significant difficulties: there are almost no mistakes
in the word formation, although children often follow a strategy close to the strategy
of avoidance: children prefer to use only the initial forms of pronouns (including
the Gen. forms of negative pronouns), so these pronouns adopt certain adverbial traits
in the speech of young children and can be seen as unchangeable. The main syntactic
features are the use of pronouns within typical constructions, acquired on the whole,
and a large number of interrogative sentences in which the pronoun is not transferred
to the beginning. Refs 26.

dc.description.abstract

value:
The article deals with the problems of forming the meaning of the media text. The author
focuses on the metatext elements of video blogs. The material of the study is the
video blogs Parthenon by Leonid Parfenov and Eschenepozner by Nikolai Solodnikov. For
the analysis of metetaxt units, the method of reconstruction of the intentional-semantic
structure of the text is used. The semantics and type of the text to which the metatext
comment is given are determined, as well as the nature of the metatext comment. The
correlation between the semantics and the type of the main text and its meta-text commentary
is revealed. The method of compositional analysis is used: the nature of the
connectivity of the main text and metatext elements, the local and global connectivity of
the compositional parts of the text and their metatext comments are determined. Semiotic
methods are used to determine the nature of the relationship between the verbal
and media components of the media text. The author distinguishes two types of metatext
elements in video blogs: written inserts and out-of-text metatext notes. The author
comes to the conclusion that at the level of local connectivity, metatext elements perform
an informative function, and at the level of global connectivity — an evaluative one. The
metatext commentary has a neutral objective character, at the level of local connectivity;
it complements the main text, expanding its referential side. Metatext elements, on the
one hand, serve to attract and retain the attention of the addressee, on the other hand,
strengthen the critical perception of the information heard. Refs 16.

dc.contributor.author

dc.description.abstract

value:
In his work How Children of the Preschool Age Observe Language, Gvozdev argued that a
child of two-three years old could fix and correct errors in the speech of other people. At the same time, numerous priming-experiments built on the data of synonymous
constructions of common language indicate that least frequency constructions willingly
used by children in this age make the greatest influence on children’s speech. The
aim of this article is to analyze speech behavior of a child who hears phrases with errors
or receives a task to repeat wrongly constructed statements. Nobody has already
studied constructions with speech errors in priming-experiments on Russian data. We
analyzed the results of a pilot experiment on Russian data developed by non-native
speakers of Russian from the Max Plank Institute for Evolutional Anthropology. There
were 33 three-year-old children involved in the experiment. The texts included random
deviations from both speech norms and frequency usage accepted in the Russian register
of communication with children. Experiment results allow making some interim
conclusions. The priming-effect on the perception of uncommon forms is low. Speech
production mechanisms started to work when performing a task to repeat phrases
heard by a child; that was followed with modifications of unusual forms, probably unconscious.
Syntactic level (word order and choice of cases and prepositions) is least
influenced by the prime. The previous speech experience also influences the ability
to repeat what a child heard. The experience includes already formed grammatical
representations of a certain child, the frequency of lexical units (including special contexts).
While facing unusual constructions, the mechanism of evaluating the statement
as “possible/impossible”, and “right/wrong” is launched which leads to its conscious or
unconscious modification. Refs 18.

dc.contributor.author

value: Eismont, Polina M.

dc.description.abstract

value:
Various experimental techniques are used in child language studies to research the
development of coherent and cohesive narrative. The most common of them are the elicitation narrative tasks based on a series of pictures or on a video, for example, a
cartoon. However, the comparison of the studies carried out using different methods
shows the results that can both coincide and significantly diverge. Among the factors
that influence the basic narrative characteristics of elicited child stories are age, the
type of visual stimulus, its length, and the way the narrative is produced (online vs. subsequent
mode). The following basic characteristics are considered to study the structure
of narratives: opening and closing markers, details and separateness of the narration,
the variety of characters and the presence (absence) of evaluation. The question
whether the type of visual stimulus has a significant effect on the basic characteristics
of children’s narratives and whether it is possible to construct a general description of
the development of narrative skills regardless of the experimental task chosen by the
researchers is discussed with a comparative analysis of oral narratives collected within
two series of experiments with Russian native monolingual children of the senior
preschool and primary school age. The analysis showed that although it is possible to
reveal some tendencies inherent in the narratives collected with different experimental
methods, the type of visual stimulus does not have any statistically significant effect on
the basic characteristics of the narratives of primary schoolchildren. Only the differences
in evaluation and closing markers in the narratives of older preschoolers, elicited
either simultaneously with watching the cartoon or during its subsequent retelling, are
statistically significant. Refs 37.

value:
The article is devoted to the interpretive analysis of the whole text in the genre of notes
of the St Petersburg writer M. N. Kuraev “Lenfilm” was!.. (2019). The work fits into a literary
series dedicated to the bygone era, evoking opposite assessments, which find
expression in irony in relation to the governing beginning of the organization of life
and respect for the creative activities of people, in this case in the field of cinema.
The author of the article attempted, on the basis of a consideration of the information structure of the text, to identify the principles of its organization: division into parts,
the order of their following, the intentional settings that determine the selection and
organization of language means. The reference to the composition of the text, which is
fundamental for the analysis, made it possible to note the features of an organization
that is different from the currently actively studied narrative: the connection of the
compositional parts in it is determined not by temporary, as in the narrative, but by
logical relations; to some initial thesis — a milestone in the presentation of content.
Such an organization, which goes back to the functional-semantic type of speech —
reasoning, does not exclude the inclusion of a “horizontal” line of development of the
semantic content of the text, a kind of leitmotif in the information structure of the text.
The variety of compositional components manifested itself in their intonational differences
associated with the emotional state of the author at the moment of description,
which is typical for ego narration, marked by a variety of intonation patterns of the text
as a whole. Semantic analysis revealed a somewhat overestimated orientation of the
author towards a common cognitive fund with the reader, which is noticeably shrinking
over time. At the same time, an assumption is made about the interest that the text can
arouse among readers of different ages. Refs 14.

The article discusses the results of a psycholinguistic experiment that is part of a
broader study of iconicity in fictional languages. The research is carried out in accordance
with the ideas of St Petersburg School of Phonosemantics, founded by
S. V. Voronin, which asserts the presence, in many cases, of both universal and specific
non-conventional correspondence between the sound form and the semantics
of linguistic units. Iconic words of fictional languages, selected in the course of phonosemantic
analysis, were presented to the participants in their sound form. The
subjects had to choose the most appropriate meaning for the sound complexes from
the contrasting meanings offered in the questionnaire. These constituted designations
of size, shape, sound, etc, which are characteristic of i conic language signs. The
respondents were native speakers of Russian and English. The survey was conducted
remotely. The analysis of the data obtained shows that the respondents react to the
word-stimuli in accordance with their universal iconic properties, and the speakers
of both non-closely related languages demonstrate similar reactions. In 17 out of
20 cases, they were able to choose the meaning originally conceived by the author
of the fictional language. The respondents’ correct choices embrace both the designations
of acoustic events and the sound-symbolic names of physiological processes
and non-acoustic properties of the signified. Thus, the hypothesis about the non-random
selection of sound forms for the transmission of meanings by authors of fictional
languages is confirmed, and this, apparently, is determined by the universal iconic
properties of linguistic systems. Refs 33.

speech are summarized. The speaker chooses intonation arrangement that is adequate
not only to external text but also to internal text. The result of speech perception
that is active mental process is an adequate comprehension of text sense that
speaker wanted to express. Inadequate intonation arrangement of text sense might
create considerable difficulties in oral speech perception process. The author argues
that speech segmentation, the direction of pitch pattern, the movement of speech tempo
and the specific type of stress, that is accentual phrasal stress, are representative of
text sense, both external and internal. Key element for cognitive speech segmentation
by speaker is existence of whole text intention and its sense segmentation. Inadequate
sense-group segmentation might depend on communication breakdown or deficiency
of intention to be understood such as control failure. Tune two instead of tune one is
distinguished in oral monologic and dialogic speech. If we interpret the external text
as a part of internal one, the new explanation of last word segmentation as well as
accentual phrasal stress and also two accentual phrasal stresses in one phrase may be
proposed. Refs 26.

title: A PARTICLE TCHUT NE (ALMOST) IN PERIPHRASTIC CONSTRUCTIONS AND THE CONTEXT OF THE SENTENCE

dc.contributor.author

value: Sretenskaya, Larisa V.

dc.description.abstract

value:
Modern linguistics studies the combination of particles with notional words as a
periphrastic construction which has a constant structure and semantics and is also
regularly used in Russian spoken speech. The paper presents the analysis of the meaning of the analytical syntactic structure with a particle tchut’ ne (‘almost’) which
implements subjective modality in the proposal and has a high emotionality and expression.
Studying the features of the meaning, structure and grammar of the periphrastic
construction tchut’ ne + V in the context of a sentence is the purpose of the
article. In this paper the context is perceived in a narrow sense as a linguistic environment
in which any given linguistic unit is used. With little emphasis having been put
on the context, the existing works have mainly been focused on the meaning of the
action which is close to completion, yet not fulfilled due to uncontrollability, surprise
and suddenness of the situation. Test material analysis revealed that constructions
with a particle almost do not only have a proximative meaning but also a contextually
determined one, i. e., the maximum exaggeration of physical states and emotions of
the subject (almost died of laughter etc.) and the controlled choice (almost said). Desemantization
of verbs and the inclusion in the periphrastic construction of causatives
provide a new meaning to it. Such type constructions as almost died from laughter,
almost said become idiomatic. The article concludes that the contextual environment
and communication goals affect the semantics of the periphrastic construction almost
+ V. Refs 22.

dc.description.abstract

value:
The history of Russophone immigration to Brazil began in the 19th century. The last
wave of Russophone immigration to Brazil began after the USSR’s collapse and continues
up to this day. There are few opportunities to study Portuguese in Russia, and
many Russophones study Brazilian Portuguese (BP) on their own after arriving in Brazil.
They learn the language in a naturalistic way and do not have any special knowledge of
the BP phonetics. One important difficulty of Russophones who learn BP is to perceive
and produce the contrast between open and closed mid vowels. In Portuguese, the
contrasts in the pairs /ε/ — /e/ and /ɔ/ — /o/ are of fundamental importance and determine
the difference in the semantic meaning of words, for example, in some homograph
pairs that consist of a verb conjugated in the first-person singular of the present
tense and a related noun. The aim of this work is to characterize the production of BP
mid vowels by Russophone immigrants in Brazil. In this work, we analyzed the audio
recordings of the words bebe [‘bεbı] ‘he drinks’, bebo [‘bebʊ] ‘I drink’, posso [‘pɔsʊ] ‘I can’
и poço [‘posɔ] ‘a well’, produced by 11 native BP speakers and 15 Russophones. For
the Russophones, these was no difference between the F1 mean values of the vowels
produced in the word pairs containing the two contrasting Portuguese mid vowels. The
results of this study provide a base for developing strategies to improve the pronunciation
of BP sounds by Russian speakers. Refs 31.

title: SIGNIFICANCE OF DECIPHERING THE ADAM ALPHABET IN THE HISTORY OF PHONETIC RESEARCH

dc.contributor.author

value: Kochetkova, Uliana E.

dc.description.abstract

value:
This study aims to consider the significance of deciphering the Hebrew alphabet for the
history of phonetic thought. Hermetic and Kabbalistic teachings endowed the Hebrew
language with a divine meaning. Traditionally considered as given to Adam by God, this alphabet was called the Alphabet of Adam. The novelty and relevance of the current
work are defined by the lack of a comprehensive description of the relationship
between these traditional ideas and phonetics. The need for it is caused by the earlier
observations about the possible influence of the 17th century concepts on the results of
later measurements of vowels with tuning forks, and by the widespread opinion about
the low significance of this period in linguistic science history. Though there can be
found some publications devoted to concrete authors of the 16th–17th centuries, their
contribution to the development of phonetic sciences has not yet been acknowledged.
The current research is based on primary and secondary sources in Latin, English,
French and Russian. The analysis showed that deciphering the vowels of Hebrew alphabet
led to the first attempt to accurately describe vowel acoustic features, the empirical
study of their articulatory characteristics and to the search for the “ideal” alphabet built
of iconic signs. It also allowed the authors to develop methods for teaching deaf-mutes
and systematize vowels. Thus the initial hypothesis about the significance of deciphering
the Alphabet of Adam for the history of phonetic thought was confirmed. Refs 25.

value:
The Antioch oration of Libanius is, on the one hand, a typical product of the sophistic
work of the orator, designed to glorify his native city, and on the other, one of the best
examples of the panegyric of the city in late ancient oratory. A panegyric to the city is a
popular genre of solemn eloquence, well studied and described in the ancient rhetorical
literature. However, Libanius’ Antioch oration is particularly interesting as the result
of the development of ancient oratory, accumulating the old rhetorical tradition and
the best achievements of ancient Greek orators in this genre, dating back to Isocrates
and to the first sophists. The discovery of the closest literary samples for the Antioch
oration allows us to determine the degree and nature of the influence of the previous
rhetoric literature (the so-called Second Sophistic) on the development of late ancient
eloquence, often referred as the Third Sophistic, as well as assess the contribution of
Libanius as a panegyrist to the history of ancient oratory. Refs 35.

title: THE RHYME AND THE FORMULA IN POPULAR FAROESE POETRY

dc.contributor.author

value: Piotrovsky, Dmitry D.

dc.description.abstract

value:
The main means which organizes the verse in popular Faroese poetry is end rhyme.
In four-line stanzas the rhyme connects the second and the fourth lines, in two-line
ones both present lines. The Faroese rhyme is not strict. It is enough only to repeat the
stressed vowel, the consonant following after might vary. The part of the word which
follows the stressed vowel may undergo significant changes. The masculine ending
sometimes rhymes with the feminine one. Even the stressed vowel might vary to
some extent. The Faroese rhyme is often trivial. The ballads on the Faroese Isles were oral. So, some special formula technique was applied for their transition. The means
of the formula technique are formulas and repetitions. The formulas are metrically
conditioned reproducible word groups having the length of one line, meanwhile the
repetitions are metrically non-conditioned sequences of different length. The formulas
and repetitions, as well as they perform the same function of the building material
for the oral poetic text, also possess the same structure. They both are composed
from permanent end variable parts. In repetitions their entwinement takes different
forms. They may follow one another, usually first comes the permanent part then the
variable one. The permanent part sometimes occupies the second half of one stanza
and then the first half of the following stanza. The permanent end variable parts
might cross one another. In this case the permanent part occupies unpair lines and
the variable part occupies pair ones. The distribution of these parts of both formulas
and repetitions is tied to the rhyming places of the verse. The rhyming word is usually
located in the variable part but sometimes it is found in the permanent part. This one
more time proves that there is no impenetrable boundary between formulas and
repetitions. Refs 8.

dc.description.abstract

value:
In this text, are given the plan and main contributions that are gathered in a collective
work directed by Prof. Georges Nivat, Les sites de la mémoire russe. The first volume,
Géographie de la mémoire russe, was published in 2007, the second one, Histoire et mythes
de la mémoire russe, in 2019. The word “site” is meant as a prominent detail in the landscape
and translated into Russian as “Uročišča”. The aim is to give a view of the main
“sites” and debates that have arisen along Russian historiography since the 18th century.
The “invention” of the “Chronicles” is one spectacular example. It goes from the first publication
in 1846 to our days. Literature, painting, and music have constructed the Russian
memory in the 18th century. Mussorgsky himself researched in the archives who were the Old believers, before writing his opera “Khovanshchina”. Ethnography appeared in
the first half of the 19th century, the came great museums at the two extremities of
the Empire, and a great number of ethnographical local museums are innumerable in
Russia, have saved a lot of artefacts during the Soviet vandalistic period. Folklore was
studied and local troubadours were registered until the end of the Soviet era. Emperor
Peter the Great was keenly aware of the importance of creating his own myth during his
lifetime, and succeeded, his role is still the main debate of Russian historiography and a
very prominent site of memory. Loss of memory began early in the Soviet regime, loss
of proletarian memory and as well as of peasant memory. Refs 9.

value: A metal-free scalable synthesis of functionalized ketenimines from alkyl α-(aryl/heteroaryl)-α-diazoacetates and alkyl isocyanides induced by blue light irradiation has been developed. The reaction proceeds at room temperature without any photocatalyst and provides ketenimines in moderate to good yields. Density functional theory (DFT) calculations and the experimental study showed that aryl(alkoxycarbonyl)carbenes in both singlet and triplet states can react with isocyanides but only the reaction of the former leads to the smooth formation of ketenimines. The obtained ketenimines were used for the synthesis of functionalized amidines under mild metal-free conditions.

dc.description.abstract

value: The method of stochastic molecular modeling, developed by the authors for calculating the transport coefficients of rarefied gas in a free medium, is generalized to describe transport processes in confined conditions. The phase trajectories of the studied molecular system are simulated stochastically, and the simulation of the dynamics of the molecule is split into processes. First, its shift in the configuration space is realized, and then a possible collision with other molecules is played out. The calculation of all observables, in particular, the transport coefficients is carried out by averaging over an ensemble of independent phase trajectories. The interaction of gas molecules with the boundary is described by mirror or mirror-diffuse laws. The efficiency of the algorithm is demonstrated by calculating the selfdiffusion coefficient of argon in the nanochannel. The accuracy of modeling is investigated, its dependence on the number of particles and phase trajectories used for averaging. The viscosity of rarefied gases in the nanochannel has been systematically studied. It is shown that it is non-isotropic, and its difference along and across the channel is determined by the interaction of gas molecules with the channel walls. By changing the material of the walls, it is possible to significantly change the viscosity of the gas, and it can be several times greater than in volume, or less. The indicated anisotropy of viscosity is recorded not only in nano-, but also in microchannels.

dc.description.abstract

value: The dynamics of the collision of two spheroidal galaxies, each of which consists of stellar and gas components inside a live massive dark halo, is considered in detail based on numerical simulations. Dark matter and stars are collisionless components, so their dynamics is modeled by the system of N body particles, and the gas component is described by the equations of gas dynamics. The calculation of gravitational forces is based on the direct summation method of the gravitational contribution from each particle, which provides the highest possible accuracy. We vary the impact parameter, the initial collision velocity, the masses of the three components for each model of galaxies in order to estimate the relative fractions of the masses that are lost by both galaxies as a result of close interactions, as well as the masses of gas and stars that are exchanged between the two galaxies during the scattering process. Estimating this exchanged mass of gas requires a Lagrangian approach to simulate gas dynamics, and the Smoothed Particle Hydrodynamics method tracks the trajectory of each smoothed particle. There are two regions of parameters that separate the merging of two objects into one (large merging) and the case of scattering, when both gravitating systems move away from each other after interaction. Collisionless components (dark matter + stars) in the interaction of approximately the same galaxies lose their maximum mass at parameters close to the boundary between merging and scattering. If the initial masses of colliding galaxies differ greatly then the lost fraction of mass is large for a low-mass object and small for a massive galaxy. The formation of global shock waves in colliding systems is a key factor determining the efficiency of sweeping gas out of the gravitational potential well. The efficiency of the stellar component transition from one object to another is negligible. Gas exchange can exceed 10 percent of the mass for a certain range of values of the impact parameter and the initial collision velocity.

dc.description.abstract

value: The theory of adjoint operators is widely used in solving applied multidimensional problems with Monte Carlo method. Efficient algorithms are constructed using the duality principle for many problems described in linear integral equations of the second kind. On the other hand, important applications of adjoint equations for designing experiments were suggested by G.Marchuk and his colleagues in their respective works. Some results obtained in these fields are also generalized to the case of nonlinear operators. Linearization methods were mostly used for that purpose. Results for Lyapunov-Schmidt nonlinear polynomial equations were obtained in the theory of Monte Carlo methods. However, many interesting questions in this subject area are remained open. New results about dual processes used for solving polynomial equations with Monte Carlo method are presented. In particular, an adjoint Markov process for the branching process and the corresponding unbiased estimate of the functional of the solution to the equation are constructed in a general form. The possibility of constructing an adjoint operator to a nonlinear one is discussed.

dc.description.abstract

value: The paper discusses issues related to the choice of the optimal damping for a system with one and a half degrees of freedom - a pendulum with an elastic-movable suspension point in the presence of viscous friction. Maximization of the degree of stability of the system is taken as an optimization criterion characterizing the efficiency of damping oscillations. Two options for installing a damping device are discussed - either in the pendulum joint, or parallel to the elastic element. The analytical solution of the optimization problem is performed in each case, and it is accompanied by a visual graphic illustration. In addition, a comparison of two cases of damping is given on the basis of analysis of the maximum degree of stability and a conclusion about the advisability of using one or another option is made. The obtained results are of interest both in theoretical and practical terms, and the described plan for finding the optimal solution can also be applied to solving other optimization problems in systems with a non-integer number of degrees of freedom.

dc.description.abstract

value: As is known, the regression analysis task is widely used in machine learning problems, which allows to establish relationship between observed data and compactly store of information. Most often, a regression function is described by a linear combination of some of the selected functions fj (X), j = 1, . . . ,m, X 2 D ⊂ Rs. If the observed data contains a random error, then the regression function restored from the observed data contains a random error and a systematic error depending on the selected functions fj . The article indicates the possibility of optimal selection of functions fj in the sense of a given functional metric, if it is known that the true dependence is consistent with some functional equation. In some cases (regular grids, s ≤ 2), similar results can be obtained using the random process analysis method. The numerical examples given in this article illustrate much more opportunities for the task of constructing the regression function.

form of constant perturbations. The stabilization is carried out by means of linear feedback.
In the problem, the feedback coefficients are calculated as optimal for the worst possible

dc.description.abstract

value:
A free descent of a finned body in resisting medium is studied. Fins are installed in such a
way that there is a regime of a translational descent with a constant speed. Beforehand, a descent of a heavy body in an autorotation mode was studied. It exists when pitch angles
of all fins are equal to each other. For a descent with autorotation, general properties
and tendencies of motion were described depending on initial conditions and parameters.
In the current paper, the descent of a body is discussed for the case when fins have equal
absolute values of pitch angles, but signs of these angles alternate. Asymptotic stability of a
translational descent with a constant speed is studied for such orientation of fins. Domains
of stability are constructed in the plane of the following parameters: pitch angle of fins
and displacement of the center of mass. Fins represented either by circle or rectangular
blades are discussed. Domains of stability are compared with that for the autorotation
mode descent. Trajectories of the center of mass are constructed. Varied types of such
trajectories are obtained when parameters of the model correspond to the case of unstable
translational descents with a constant speed.
