dc.description.abstract

value:
The article is dedicated to the analysis of line managers’ role and position in modern Russian business society, as well as the membership of line managers in the socio — professional group of managers. Line managers were considered as the owners of specific capital
(physical, human, social and administrative), distinctive for managers’ group. The author
focuses on administrative capital as the most important management authority indicator.
The empirical part of the work was based on the results of a standardized survey of 1116 line
managers in 400 organizations from 11 industries. The results indicated that modern Russian managers have high levels of physical, human, social capital, and, moreover, quite a
high level of administrative capital that is close to middle and top levels. Line managers
have significant authority in terms of control, organization, and planning, as well as fairly
high power in HR and finances compared to the results of previous studies. The results
demonstrated the evolution of a line manager from supervisor to a full-fledged manager
with a higher level of education, salary, authority, and social status. Therefore, line managers
can be assigned to the socio-professional group of managers and line managers should be
included in research on social and managerial topics. Moreover, they should be investigated
as an independent phenomenon. Line managers can become a fundamental potential in the
struggle for a competitive advantage during a crisis and an unstable economy, they deserve
attention from both the scientific and business sphere.

Vestnik of Saint Petersburg University. Arts 10, no. 3 (2020): 475–487.

dc.description.abstract

value:
The article is dedicated to the problem of communication between Soviet and British architects in the period of 1920–1930s, which is very poorly studied in Russian and British historiography. The subject is thoroughly considered in two ways simultaneously. The author
examines the political and socio-economic circumstances of such business trips in England.
The main focus is on the professional goals and objectives of these visits, and on the reception
and interpretation of Soviet architectural and urban planning practices by British architects. The second aspect to which attention is paid are the main points of the program for displaying
Soviet architecture, which was organized by the host country. Since a number of visits to the
USSR by foreign architects took place in the early 1930s, the nature of mutual interest in the
creative experience of Soviet and English colleagues has been changing over the decades. The
main objective of the work was an attempt to consider, to a first approximation, the initial
stage of this relationship (late 1920s — 1930s) and the most important forms of communication between English and Soviet architects. The article analyses events organized by VOKS,
Inturist, Soviet trade representatives, Society for Cultural Relations between the People of the
British Commonwealth, and the Union of Socialist Soviet Republics. The work used materials
from the Russian and British archives, including previously unpublished records of Berthold
Lubetkin and Erno Goldfinger.

dc.description.abstract

value:
The article focuses on developing and clarifying the main concepts that would form the basis
of an integral model of social development. Previous models (Bell, Toffler) were developed
in the second half of the last century and now have lost the ability to correctly describe and
explain modern social trends and tendencies. This fact, as well as the growing criticism of the
idea of social development in post-industrial societies, sets the task for sociologists to develop
a relevant theoretical and methodological foundation for studying modern society. The purpose of this work is to develop a conceptual scheme that would be adequate to current ideas
about the social structure and forms of social interaction, and which would also form the basis
of an integral model of social development. The analysis of previous models illustrated their
integrative potential, which, nevertheless, should be clarified. An emergent level of analysis,
coupled with the principles of integralism, made it possible to develop a theoretical scheme
of the process of reproduction of structure and action that complements the existing ones
(Giddens, Archer) and makes it possible to avoid the limitations of empirical uncertainty of
structure and action. The emergent state of social form is considered to have a spatiotemporal
reference, which allows an empirical fixation of its characteristics. In addition, the author proposes the concept of abstract and individual rationality when an individual is considered as
an independent actor, who does not always follow mutual norms. The concepts developed in the article are meant to further development of integralism in general and integral modeling
in sociology in particular.

dc.description.abstract

value:
In this article, the 125-year history of the Gnesin system of musical education is examined.
The thread that runs through its long history is the spiritual culture of the Silver Age with its
traditions, values, outstanding teachers, as well as both performers and talented leaders. The
Gnesin family highly valued the concepts of the Silver Age. They managed to create an inimitable system of musical education that is marked by its patriotic way of thinking, devotion to
music, and loving attitude towards students. The article focuses on the figure of Elena Gnesina
who was drawing herself on the high spiritual culture of the Silver Age and devoted herself
entirely to the music, demonstrated her commitment to the students, and protected them
even in the most difficult times regardless of the social environment: revolutions, the First and
Second World Wars. The passion for her work, which Gnesina demonstrated throughout her
72-year life, has been reverently passed from generation to generation by the Gnesin system’s
teachers. Nowadays, all educational institutions — the school, two colleges and the institute —
continue to accumulate spiritual traditions, constantly giving rise to new fields and profiles of
professional education that respond to the challenges of the time and strengthen the position
of the Gnesin system of education both in Russia and abroad.

Vera Borisovna Kazarina is the head of Pokrov, a workshop of the Ancient Russian Church
Embroidery of the Constantino-Eleninsky Convent, Candidate in History of Arts, and a member of the Union of Artists of Russia. The article examines her active creativity, research and
educational work in modern Church art, in particular, icon embroidery. As a researcher, she
collects ancient samples of church embroidery, masters the ancient iconography, reveals the
symbolism of Orthodox ornaments, studies the origin, history, and features of ancient gold
embroidery workshops, as well as reconstructs traditional embroidery techniques. She collected, classified and described different types of pictorial and gold embroidery. V.B.Kazarina defended her Candidate of Art History dissertation and used it as a basis for her monograph “Old Russian Ornamentation on Hanging Shrouds of the 16th Century” (2014). As
a high-profile embroiderer, Vera Borisovna creates her unique embroidered icons with images
of ancient and newly appeared saints, artistically embroidered clothing for the liturgy. Kazarina creates most of her works independently. The largest works are performed together with
other embroiderers from Pokrov workshop, which she established and oversees. Her customers are numerous monasteries and churches of different dioceses. As an educator, Vera Kazarina works to popularize the history, spiritual foundations, and culture of Russia. Researchers,
curators of museum collections, and practicing embroiderers come together to share their
knowledge. Vera Borisovna writes research and popular articles, hosts TV programs, and runs
virtual distance courses on church embroidery. With her enthusiasm, creative, practical, and
educational activities, Kazarina contributes to the development of the modern Saint Petersburg school of icon embroidery with its own artistic style. Her life and her creative path is an
example of spiritual and creative service to people, and her works are a valuable contribution
to the modern development of Russian art.

dc.description.abstract

value:
The article discusses groups of subjects of media speech criticism of the Irkutsk writers organization’s newspaper “Literary Irkutsk” of the late 80s — early 90s in the twentieth century. It is
proposed to classify writers, poets, and playwrights as subjects of criticism of media speech,
along with representatives of the academic sphere, employees of media organizations, and
public activists. The expansion of the group of critics of media speech is justified by multiple
objective and subjective reasons. Groups of media speech critics are structured into two communities — professional and non-professional communicators. The main areas of criticism of
media speech in the corporate publications are identified. It has been established that effective
aspects of publications (media rhetoric) are relevant if they criticize excessive or insufficient
expression of texts, rhetorical arguments of logos and pathos, unfair work with illustrative and
factual material, and manipulative tactics. The criticism of media speech acquires a resource
and situational-speech perspective (stylistics of media speech) while analyzing stylistic violations in the media, analyzing extralinguistic factors that influenced the individual style of
media authors, and when describing ideological prohibitions on the stylistic use of language
options. Linguistic-legal and linguistic-ethical aspects of criticism (linguoconflictology) involve an analysis of the speech “abuses” of media from the standpoint of ethics and law. The
specificity of the inclusion of critical comments of various sizes in different structural and compositional parts of the materials of “Literary Irkutsk” is shown. Three methods are presented — “point”, “fragmentary”, and “text” — the introduction of media speech criticism into
problematic articles, op-ed articles, readers’ letters, rebuttals, and commentary from “Literary
Irkutsk”.

dc.description.abstract

value:
In 1957 the Sociology program was opened at the University of Buenos Aires. This moment
of institutionalization of Sociology is viewed as the end point of the previous period, giving
place to a new time of scientific, academic, and professional development of the discipline.
However, the foundation of Sociology as an academic discipline did not lead to the end of the
debate and struggle over the definition of its essence, functions in society, and ways of teaching. This article attempts to outline the development and institutionalization of Sociology in
Argentina from the 1950s to the present day at the University of Buenos Aires. Underlining
the importance of the political climate for the development of the Argentinian sociology, the
author divides the process into three stages according to the discipline’s relations with the
political regime: the first stage (1957–1966) includes the foundation of the Sociology career
at the University of Buenos Aires as part of the academic project of its creator, Gino Germani;
the second stage (1966–1983) is characterized by the growing politicization of the discipline
against the background of political repression and military dictatorship; and the third stage
(from 1983 until now) is the period of the renaissance of Sociology at the University and its
professionalization in the context of the democratization of political life in the country. The
stages are characterized by the actors involved in the struggle to determine, what sociology is,
what sociologists do and how the sociological education should be. Finally, despite conflicts
between actors, political repression, economic turbulences, budget constraints, ideological
stigmatization, and the attempt to eliminate discipline during the military dictatorship, Argentinian sociology has managed to consolidate and provide a scientific understanding of the
modern world.

dc.description.abstract

value:
In the article, Maksim Kovalevsky’s work is considered as a prehistory of Russian youth sociology. His understanding of the essence of upbringing is analyzed (not grouping everyone under
one pattern, but the development of individual characteristics; the relationship of socialization
and individualization, a combination of duty to society and freedom of personal self-determination) and the main agents of upbringing (family and school). The sociologist’s emphasis
on the evolutionary nature of social development determined the impossibility of simultaneously creating a new system, a new religion, and morality. The family is the main center for
the upbringing of youth. Its history is the history of intergenerational relations with the following perspective: the family as a “pacified environment”. It serves as the rationale for the
transition from traditional education (submission and obedience of youth) to “leadership of
the ascending generation”. Education is a holistic process (inseparable from accomplishment),
the assimilation of the beginnings of a universal human culture. The sociologist’s guideline is
access to education, removing social barriers to education. He determined the problems of
equality (inequality) in regard to origins, the chances of youth, and the connection between
education and self-education. The most important function of the university is education, the
upbringing nature of direct communication between teachers and students, its “reverse” effect
on educators, the significance of interpersonal communication in the student community, and
student self-government. The university is a hotbed of “guiding currents of social thought”.
The article presents the importance of the educational value of sociology, synthesizing the
principles of human society. The authors emphasize that taking into account the experience
of others in teaching and upbringing (reaching the level of world science and literature as well
as the “rejection of blind imitation”) plays an important role. In conclusion, the prospects for
further analysis of the problems of individual areas of youth education in the work of Kovalevsky are determined.

dc.description.abstract

value:
The purpose of this article is to discuss the dialectical application of the Soviet experience in
the construction of socialism in China. Mao Zedong formulated the thesis “Follow the path
of Russia”, thereby explaining the strategy for transformation of Chinese society. China in
those times experienced economic difficulties of the pre-industrial stage of development, and
“following the path of Russia” meant taking Marxism as the guiding ideology and developing
along the path of socialism, overcoming internal and external barriers. The authors of the
article illustrate how the Soviet experience was differentiated by the Chinese leadership: Mao
always divided the Soviet experience into a basic experience and a specific experience. The
former reflects the common laws of human society at specific stages of development, while the
latter is the specific form of realization of these laws, divided into the part verified by practice
and learnable, the part that is only applicable to the USSR and the wrong part that must be
abandoned. “Following the path of Russia” encouraged the new China to complete the tasks
left by the Chinese Democratic Revolution, quickly establish a relatively complete national
economic system and continuously improve its international status. From this theory to “Taking China’s own way”, it is required to continue to adhere to the road of scientific socialism
and the development of socialism with Chinese characteristics in the new era. An analysis of this theory is not only crucial for China to follow the path of socialism with Chinese characteristics, but also helps scientists, researchers, and politicians in many countries around the
world to understand the path of socialism’s development with Chinese characteristics, better
understand history and Chinese culture, and promote the exchange of world culture more
successfully.

dc.description.abstract

value:
The article attempts to fill the gap in the field of rural sociology and answer the question what
types of intuitive models of the “image of the future” of the village are formulated today by entrepreneurs (farmers) of the North-West Economic Region of the Non-Black Earth Region of
the Russian Federation (hereinafter referred to as the Non-Black Earth Region). The object of
the study was the model of “images of the future” in the village of Non-Black Earth. The subject of the study is the idea of rural entrepreneurs about the “image of the future” of the village
of Non-Black Earth, their description of the model of this image. Taking into account the fact
that the “image of the future” is a multidimensional and complex metaphorical phenomenon,
the authors have compiled a research strategy so that in the course of an expert interview
the respondents could model the “image of the future” in the village based on 4 meanings:
“image of the past” “The village of Non-Black Earth, the” image of the country “(Russia),
the” image of the present “village and, derived from them — the” image of the future “of the
village. The survey was conducted using informal expert interviews. The experts were rural
entrepreneurs-heads of peasant farms (N = 32, 34–68 years). A generalization of field research
materials allowed us to distinguish two types of models of the “image of the future” in the
village of Non-Black Earth: the model “kamikazde” and the model “siren”. Time lag models:
50 years. Models of “images of the future” of a “kamikaze” type village were created by pessimistic respondents. Models of “images of the future” in the village of “sirens” were created
by optimistic respondents.

dc.description.abstract

value:
We consider sequences of random variables with the index subordinated by a doubly
stochastic Poisson process. A Poisson stochastic index process, or PSI-process for short,
is a random process ψ(t) with the continuous time t which one can obtain via subordination of a sequence of random variables (ξj ), j = 0, 1, . . ., by a doubly stochastic Poisson
process Π1(tλ) as follows: ψ(t) = ξΠ1(tλ)
, t > 0. We suppose that the intensity λ is a nonnegative random variable independent of the standard Poisson process Π1. In the present
paper we consider the case of independent identically distributed random variables (ξj )
with a finite variance. R. Wolpert and M. Taqqu (2005) introduce and investigate a type of
the fractional Ornstein — Uhlenbeck (fOU) process. We provide a representation for such
fOU process with the Hurst exponent H ∈ (0, 1/2) as a limit of scaled and normalized
sums of independent identically distributed PSI-processes with an explicitly given intensity λ. This fOU process, locally at t = 0, approximates in the square mean the fractional
Brownian motion with the same Hurst exponent H ∈ (0, 1/2). We examine in details two
examples with the intensity corresponding to the R. Wolpert and M. Taqqu’s fOU process:
a telegraph process, arising for ξ0 having the Rademacher distribution ±1 with probabilities 1/2, and a PSI-process with the uniform distribution for ξ0. For these two examples we
derive exact and asymptotic formulae for a local modulus of continuity over a small time
interval for a single PSI-process.

dc.description.abstract

value:
The present article is the sixth in a series of papers dedicated to two-dimensional cubic
homogeneous systems. It considers a case when a homogeneous polynomial vector in the
right-hand part of the system does not have a common factor. A set of such systems is
divided into classes of linear equivalence, wherein the simplest system being a third-order
normal form is distinguished on the basis of properly introduced principles. Such a form is
defined by the matrix of its right-hand part coefficients, which is called the canonical form
(CF). Each CF has its own arrangement of non-zero elements, their specific normalization
and canonical set of permissible values for the unnormalized elements, which relates the CF
to the selected class of equivalence. In addition to classification, each CF is provided with:
a) conditions on the coefficients of the initial system, b) non-singular linear substitutions
that reduce the right-hand part of the system under these conditions to the selected CF,
c) obtained values of CF’s unnormalized elements. The proposed classification was primarily
created to obtain all possible structures of generalized normal forms for systems with CF in
the unperturbed part. The article presents another application of the resulting classification
related to finding phase portraits in the Poincare circle for CF.

dc.description.abstract

value: Numerical modeling of nonequilibrium state-to-state carbon dioxide kinetics is a challenging time-consuming computational task that involves solving a huge system of stiff differential equations and requires optimized methods to solve it. In the present study, we propose and investigate optimizations for the extended backward differential formula (EBDF) scheme. Using adaptive timesteps instead of fixed ones reduces the number of steps in the algorithm many thousands of times, although with an increase in step complexity. The use of parallel computations to calculate relaxation terms allows one to further reduce the computation time. Numerical experiments on the modeling of spatially homogeneous carbon dioxide vibrational relaxation were performed for optimized computational schemes of different orders. Based on them, the most optimal algorithm of calculations was recommended: a parallel EBDF-scheme of fourth-order with an adaptive timestep. This method takes less computational time and memory costs and has the high stability.

, defined on a segment and subject to certain
boundary conditions. A subspace X of dimension not exceeding n is called optimal for a
function class A if the best approximation of A by X equals the Kolmogorov n-width of A.
These boundary conditions correspond to subspaces of periodically extended functions with symmetry properties. All of the approximating subspaces are generated by equidistant shifts
of a single function. The conditions of optimality are given in terms of Fourier coefficients
of a generating function. In particular, we indicate optimal spline spaces of all degrees
d > r − 1 with equidistant knots of several different types.

dc.description.abstract

value:
We study the diffeomorphism of a plane into itself with three fixed hyperbolic points. It
is assumed that at the intersections of the unstable manifold of the first point and the
stable manifold of the second point, the unstable manifold of the second point and the
stable manifold of the third point, the unstable manifold of the third first point and the
stable manifold of the first point are heteroclinic points. The orbits of fixed and heteroclinic
points form a heteroclinic contour. The case is studied when stable and unstable manifolds
intersect non-transversally at heteroclinic points. Among the points of non-transversal intersection of a stable manifold with an unstable manifold, first of all, points of tangency of
finite order are distinguished; in this paper, such points are not considered. In the works
of L. P. Shilnikov, S. V. Gonchenko and other authors studied diffeomorphism with heteroclinic contour, it was assumed that the points of non-transversal intersection of a stable and unstable manifolds are points of tangency of finite order. It follows from the works of
these authors that there exist diffeomorphisms for which there are stable and completely
unstable periodic points in the neighborhood of the heteroclinic contour. In this paper, it
is assumed that the points of a non-transversal intersection of a stable and unstable manifolds are not points of tangency of finite order. It is shown that in the neighborhood of
such a heteroclinic contour two countable sets of periodic points can lie. One of these sets
consists of stable periodic points, whose characteristic exponents are separated from zero,
the second — from completely unstable periodic points, whose characteristic exponents are
also separated from zero.

It is well known for non-injective endomorphisms that if for every point the set of preimages
is dense in the manifold then the endomorphism is transitive (i. e. there exists a point that
its orbit is dense in the manifold). But it has not yet been completely investigated that if
the pre-orbit of points are dense under Anosov endomorphisms or what are the necessary
conditions that make the pre-orbits of each point dense. By making a great use of the
integral lattice properties, we construct our proof on the pre-image sets of points under
the iterations of the linear dynamical system. We introduce a class of hyperbolic linear
endomorphism that is called absolutely hyperbolic and show that if A : Tm → T
m is an
absolutely hyperbolic linear endomorphism of degree more than 1 then the pre-orbit of each
point is dense in Tm.

value:
The stochastic mesh method for solving a multidimensional optimal stopping problem for
a diffusion process with non-linear payoff is considered. To solve the problem in the case
of payoff for an Asian option with geometric average we provide a special discretization
scheme for the diffusion process. This sampling scheme allows one to get rid of singularities
in transition probabilities. Then, we consider transition probabilities of a stochastic mesh
defined as averaged densities. Two estimates of the solution to the problem by the stochastic
mesh method are given. The consistency of the defined estimates is proved. It is shown that
the variance of the solution estimates is inversely proportional to the number of points in
each mesh layer. The result extends the application area of the stochastic mesh method.
A numerical example of the result is presented. We applying estimates to the call and put
options compared to the option prices obtained through the regular mesh.

dc.description.abstract

value:
A mathematical model of damped oscillations of three-layer plates formed by two rigid
anisotropic layers and a soft middle isotropic layer of a viscoelastic polymer is proposed.
Each hard layer is an anisotropic structure formed by a finite number of randomly oriented orthotropic viscoelastic composites layers. The model is based on the use of the
Hamiltonian variational principle, the refined theory of first-order plates (Reissner-Mindlin
theory), the model of complex modules and the principle of elastic-viscoelastic correspondence in the linear theory of viscoelasticity. When describing the physical relationships of
hard layer materials, the influence of the vibration frequency and the ambient temperature
is considered negligible, while for the soft layer of a viscoelastic polymer, the temperaturefrequency dependence of the elastic-dissipative characteristics is taken into account based
on experimentally determined generalized curves. As a special case of the general problem,
by neglecting the deformation of the middle surfaces of the rigid layers in one of the directions of the axes of the rigid layers of a three-layer plate, the equations of longitudinal
and transverse damped oscillations of a globally orthotropic three-layer beam are obtained.
Minimization of the Hamilton functional allows us to reduce the problem of damped vibrations of anisotropic structures to the algebraic problem of complex eigenvalues.

An efficient numerical tool for studying shock waves in viscous carbon dioxide flows is proposed. The developed theoretical model is based on the kinetic theory formalism and is free
of common limitations such as constant specific heat ratio, approximate analytical expressions for thermodynamic functions and transport coefficients. The thermal conductivity,
viscosity and bulk viscosity coefficients are expressed in terms of temperature, collision
integrals and internal energy relaxation times. Precomputed in the wide temperature range
thermodynamic functions and transport coefficients are implemented to the numerical code
which is used for the simulations of the shock wave structure. Including the bulk viscosity
to the kinetic model results in the increasing shock width and improves the agreement with
experimental data.

dc.description.abstract

value:
According to numerous studies of different types of composite materials was found that
the main processes of fatigue fracture in these materials are caused by the accumulation
of damage. The measure of damage is determined by various degradation processes of the
material: the fibers fracture, delamination, destruction of the matrix, the joint destruction
of the matrix and fibers, separation on the interface, re-inclusion. The sequence of these
damages can be various up to full fracture of a material. Unlike metals, for which the formation and development of cracks are the main mechanisms that determine the durability
of the material, for composite materials, these mechanisms are determined by the kinetics
of the development of the damaged state until the final fracture. The cumulative damage
accumulation curve is an increasing function of the time (number of loading cycles) until the
moment of macro-fracture. In the general formulation of the kinetic equation for the damage parameter was considered in the works of Howard and Bokshitsky. According to these
works, the damage of the system, in accordance with the conception of statistical physics,
proceeds at a rate that depends on some external factors (mechanical, physical, chemical,
etc.), as well as the value of the accumulated damage. Since that the real materials have a
random structure, therefore, the continuity or damage parameter is a statistical index. This
index can defined using a kinetic equation, the right part of which is given in the form of a
power dependence on the value of the effective stress. The given conception was used in the
works of Kachanov-Rabotnov and on its basis, the criterion of brittle fracture under hightemperature creep was formulated. In this paper, the damage conception is used to describe
the damage processes of composite materials and the formulation of the fatigue strength
criterion. The relative changes of the elasticity modulus in the process of cyclic loadings is
considered as a continuity (damage) parameter. The critical value of damages is accepted
as a fracture condition and on this basis the criterion of fatigue strength is formulated. The
coefficients of the criterion are concretized and damage accumulation curves and fatigue curves are plotted. A good agreement between the theoretical damage and fatigue curves
with the results of the corresponding experiments on the fatigue of carbon fiber plastics is
observed.

Transverse vibrations of an inhomogeneous circular thin plate are studied in the paper. Nondimensional equations based on Kirchhoff — Love hypotheses describing nonaxisymmetric vibrations of inhomogeneous plate are derived. Using the perturbation method, asymptotic
formulas are obtained for the free vibration frequencies of a plate, whose thickness and
Young’s modulus linearly depend on the radial coordinate. The influence of the plate edge
conditions on the frequencies and the behavior of frequencies for a plate with the fixed
mass are analyzed. For the lower free vibration frequencies the results of asymptotic and
finite elements analyses are compared.

value:
Migratory birds use several different sources of orientation information. They
have at least three compass systems based on different cues: the sun and polarized light, the stars and their constellations, and the geomagnetic field. The
concurrent information obtained from these three compasses is redundant,
therefore the compasses need to have a hierarchy and must be calibrated relative to each other. One of the compasses should dominate the others, or some
orientation cue should be used to calibrate the remaining compass systems.
Results of experiments on a variety of songbird species demonstrate that while
astronomical cues calibrate the magnetic compass during the pre-migratory
period, strategies used during the migratory period are more diverse. In the
present review, we analyze the results of all crucial cue-conflict studies, mostly
performed in nocturnal songbird migrants; we also try to understand why some
migratory species calibrate their magnetic compass on sunset cues while others use the geomagnetic field or stars as a primary cue source, and we examine
why the previous hypothesis could not explain the findings of all cue-conflict
experiments

dc.description.abstract

value:
Left-eye preference, implicating right hemisphere advantage, is typical for vigilant
behaviour of many vertebrates. Nevertheless, lateralization of vigilance may be
manifested in other ways, such as different reactions to the danger viewed with
the right and left eye. Here, we studied one-side biases in the orientation of whitefronted geese Anser albifrons feeding in flocks at different distances to the source
of anthropogenic disturbance (a road with traffic) and in flocks of different sizes.
The birds which used the left eye to monitor the road were at shorter distances
to the road than the birds which used the right eye. The tendency to monitor the
road with the right eye decreased with increasing flock size. Trade-offs between
feeding, social and vigilant behaviour could explain these tendencies.

dc.description.abstract

value:
The adaptive cardiovascular reactions of the human diving reflex were studied.
The diving reflex was activated by submerging a face in cold water under laboratory conditions. Forty volunteers (aged 18–24) were examined. ECG, arterial
blood pressure (ABP) and central blood flow were recorded by the impedance
rheography method in resting state, during diving simulation (DS) and after
apnea. During DS there is a statistically significant decrease in the dicrotic index (DCI), which reflects a decrease in the resistive vessel tone and as well as
diastolic index (DSI), characterizing lung perfusion. A comparison of the latent
periods (LP) of an increase in ABP and a drop in DCI showed that a decrease in
pulmonary vascular tone develops faster than ABP begins to increase. The LP
for lowering DCI is from 0.6 to 10 s; for an increase in ABP — from 6 to 30 s. A
short LP for DCI and the absence of a correlation between a decrease in ABP
and DCI suggests that a decrease in pulmonary vascular tone during DS occurs
reflexively and independently of a change in ABP.

The native habitat of the brown bullhead Ameiurus nebulosus is located in the
eastern part of North America. This species was introduced in Europe, Southwestern Asia and New Zealand. It was supposed that it entered Russia from the
southwest and now inhabits some water bodies at the border with Ukraine and
Belarus. Information about bullheads in Russia was searched for in scientific
editions and angler’s blogs. Anglers’ reports have been verified by survey and
fishing. It turned out that brown bullheads did in fact appear in Russia, but not
where they were expected: they were found by the city of Saint Petersburg
on the Karelian Isthmus, i.e., on the territory between Lake Ladoga and the
Gulf of Finland of the Baltic Sea. They inhabit at least three lakes. This invasion
resulted from release by unauthorized individuals. The revealed habitats are
linked by brooks with the river systems of the Baltic Sea Basin. The following
spread of the brown bullhead is possible due to intentional releases and natural processes.

dc.description.abstract

value:
The article is focused on doctor-patient relationships in neonatological and pediatric medicine we want to specify the practice. I feel the term “pediartic medicine” repeats itself, moreover medicine includes theoretical knowledge about treatment but we want to emphasize
practice where the child is the patient since he is the one who receives medical care but all
communication is conducted with his caregiver/legal representative and this constitutes a
specific feature of these relationships. Neonatologists and pediatricians are the first professionals that the mother-child/legal representative see, and they are the ones with whom the
caregiver discusses the child’s physical and mental health, as well as development. An important aspect of this relationship is compliance. The authors note that compliance is indirect
due to the tripartite relationship, where the doctor’s recommendations in the interests of the
child are carried out by his legal representative; at the same time, the success of the treatment and competent child care depend on the quality of this compliance. Significant aspects
of compliance are identified by the authors: the doctor’s psychological literacy, the ability to
establish trusting relationships with the caregivers relationships should be build BOTH with
caregiver AND a child, this is important, and the ability to consider individual characteristics
and emotional state of a caregiver while discussing a child’s health and providing the necessary prescriptions. This all influences the caregiver’s compliance which in turn leads to high
quality childcare, treatment, and recovery, as well as a child’s physical and mental health.
Special attention is given to the ability of a neonatologist/pediatrician to observe, during
examination, behavioural manifestations that may indicate a risk of developing emotional difficulties and mental health disorders, and to refer the child and caregiver here was a misprint to a psychologist or psychotherapist for a consultation. This is an important factor for
treating and preventing socio-emotional and mental health problems as early as possible.
In the conclusion, the authors describe the main areas of psychological work with medical
professionals in neonatological and pediatric care while also discussing the necessity of a
systemic approach in psychological services at medical units.

The article presents the results of a study of factors associated with the risk of HIV infection among young people in St. Petersburg. The research was conducted using the crosssection method in the period from 2016 to 2019, and 1,256 people participated from ages
17–26 years old. Using a structured interview, data was obtained from participants’ answers
on their awareness of HIV. The interview was aimed at revealing the subjective risk amongst
young people and learning how they perceive HIV can be transmitted. The interview also
looked at how HIV can be avoided, i. e, using a condom during sexual contact, abstinence,
refusal of intravenous drugs, etc. An assessment was made of the various methods of avoiding HIV and correlation between the factors. The analysis of the data demonstrated that
the level of student awareness on the topic of HIV is relatively high at 75.6 % and it did not
change significantly throughout the four years of the study. The number of students that associated themselves at risk is 31.5 %, therefore 68.5 % did not consider themselves at risk.
These numbers also did not significantly change throughout the study. 51  % of students
practice behaviour that excludes the main risks of HIV transmission, which include the
above mentioned; no intravenous drugs, no sexual contact, using condoms, etc. The remaining 49 % did not carry out sufficient behaviours to keep infection rates to a minimum,
22.5 % of the these participants did not confirm the use of condoms for every sexual encounter; 25.5 % of the people who did not confirm if they use condoms for every sexual act,
said that they do not use condoms as they have one regular partner. The study did not demonstrate significant statistical correlation between the level of HIV awareness and behavioural practices for avoiding transmission. This suggests the need to build a more complex
research model, to formulate broader prevention tasks, including not only information, but
psychological components — the impact on a personal assessment of the risk of infection
and on specific behavioural risk patterns.

dc.description.abstract

value:
The article presents an analysis of literary sources on the topic of psychological adaptation
to pregnancy and motherhood. Psychological adaptation can be defined as the process of establishing the optimal correspondence of the individual and the environment during the implementation of human-specific activities, which allows the individual to meet urgent needs
and realize significant goals, while ensuring compliance with the maximum human activity,
behaviour, and environmental requirements. Psychological adaptation is a continuous process, which also includes such aspects as optimization of the constant impact of the individual with the environment and establishing an adequate correspondence between mental
and physiological characteristics. Pregnancy and motherhood as situations of adaptation are
due to two circumstances: adaptation to pregnancy as a physiological and psychosomatic
condition; adaptation to motherhood as the adoption of the role of a mother and the formation of a mother’s position, the adoption of a child and all changes related to the appearance in the personal, family, social and professional spheres. In this process, all physiological
and psychological adaptation systems are involved, and the very situation of pregnancy and
motherhood can be considered as an acute crisis situation, since there is a radical change
in all aspects of a woman’s life. The article discusses in detail the factors affecting a woman’s
adaptation to pregnancy, in particular the lack of adaptation mechanisms, motivational factor (conflict), and the presence of objective reasons that complicate the adaptation process.
The concepts of prenatal, maternal, and parental stress are presented. Also, the features of
coping strategies are discussed and the results of modern research on the topic are presented.
The current sphere requires more detailed research and additional studies based on a single
theoretical and methodological model, taking into account all ethical standards when conducting studies with a person, since pregnant women are included in a vulnerable group of
respondents.

dc.description.abstract

value:
Low adherence to treatment of chronic diseases, in particular coronary heart disease, is noted
as a circumstance leading to a negative outcome. The issue of assessing adherence to treatment
remains unsolved, especially due to the necessity of taking into account a whole range of behavioral aspects (control of blood pressure, diet, recommended physical activity, etc.), not just
adherence to pharmacotherapy, which is associated with the characteristics of the treatment
of the disease. The study of patient’s behavior in the therapy process, as well as a differential
assessment of his/her adherence to different kinds of treatment, is a complex task that must
be faced by the multidisciplinary team managing the patient: the physician and the clinical
psychologist. Thus, the aim of the study consisted in developing a specialized questionnaire
for assessing the behavior associated with adherence to treatment among patients with cardiac
pathology in the postoperative period. The questionnaire developed by the authors is provided
in the appendix. A detailed analysis of the data obtained from a group of 103 patients suffering from coronary heart disease and undergoing coronary artery bypass surgery, using the
above-mentioned 8-scale questionnaire, confirmed that all the studied behavioral aspects are
significant for determining adherence to treatment. As a result of the factor analysis of the questionnaire parameters, three main factors were obtained, which can be used for a more differentiated description of patients’ behavior in the therapy process. These factors were labeled
as “medical”, “physical condition”, and “bad habits”. The article illustrates a practical example
of how a patient sample can be divided according to the above factors for further detailed
study of their psychological and clinical characteristics.

dc.description.abstract

value:
Current theoretical models of addictive disorders view addictive behaviour as a way to prevent
or avoid a negative emotional state. The mechanisms of emotional regulation mediate the effect
of stressors on human behaviour, allowing the formation of more or less adaptive behavioural patterns. Deficits of emotional regulation are described in many substance abuse disorders and
are seen as a multifaceted construct that includes lack of awareness, comprehension, and acceptance of emotions, inability to control behaviour during emotional experiences, lack of access to
adaptive strategies to change the duration or intensity of negative emotional experiences, and
unwillingness to experience emotional stress. The recognition of emotions by facial expression
is extremely important for the ability to form and maintain a social relationship because it allows
you to quickly (automatically) decode the emotional state of another person and adapt your behaviour relative to these social cues. The fundamental question of the relationship between the
mechanisms of regulation of one’s emotions and recognition of other people’s emotions by facial
expression remains insufficiently studied at the moment. This article aims to present relevant
research in the field of studying disorders of emotional regulation and recognition of emotions
in substance use disorder, and to determine the relationship between these phenomena with a
further assessment of the significance for the prediction and therapy of addictions.

The problem of changes in brain activity in patients with somatic diseases in connection with
the main pathology and due to surgical treatment is of particular importance in regard to an
increase in the proportion of the population with cardiovascular diseases. The issue is significant with respect to the challenges of social rehabilitation of patients. The article discusses
the results of a study of the cognitive functioning of patients with various cardiovascular diseases at the stage of preparation for high tech operations on the vessels of the heart. In total,
98  patients took part in the study, including 35  patients with chronic heart failure (CHF)
III–IV functional classes (FC) (according to the New York Heart Association — NYHA) and
systolic dysfunction of the left ventricle (LV), whose average age was 50.97±11.24 years, and
63 patients with coronary heart disease (CHD), the average age was 55.95±5.97. The study
was carried out using a psychodiagnostic complex, including clinical, psychological, and experimental psychological research methods, which included the “method of series connections” (in the original “Trail Making Test — TMT”); subtests of “Similarity” and “Koos Cubes”
from “the Wechsler Adult Intelligence Scale” Research; pathopsychological tests “10 words”,
“Memorization of Stories”, “Simple Analogies”; “Test of Visual Retention” by A.Benton; “Scab
Interference Test”. The results of a comparative analysis of socio-demographic, individual psychological characteristics, as well as the main indicators of the cognitive sphere of patients
with CHF and CHD, preparing for heart transplantation (HT) and coronary artery bypass
grafting (CABG), are presented respectively. It was shown that patients with CHF demonstrate
lower results in the main parameters of cognitive functioning (memory, attention, thinking)
(p≤0.05), more often complain of subjective deterioration in memory and attention, have
more optimistic ideas about future treatment prospects, and the outcome of the upcoming
heart surgery. The results obtained contribute to a deeper understanding of the specifics of
neurocognitive deficiency and its causes, and also allow for the optimization of rehabilitation
measures taking into account the data obtained.

dc.description.abstract

value:
The article presents the results of a study of emotional and behavioural features of children
with autism spectrum disorder (ASD) using the Child Behaviour Checklist (CBCL/1½-5).
The use of this instrument to assess behavioural disorders and as a screening method in
children with autism spectrum disorder is a new area of its application. Studies conducted
previously in Europe, the USA, and South Korea have demonstrated that the DSM-Pervasive
Development Problems and Withdrawal scales are the most sensitive in detecting autism
spectrum disorder at the preschool age. We have not found any studies performed on a
Russian sample of children in which behavioural features were studied using the CBCL/1½-
5 method in children with ASD. Participants of the study included 28 children with ASD
(average age: 52,9± 8,7  months) who were diagnosed by a psychiatrist during examination in the Stavropol Clinical Psychiatric Hospital №1 and 29 typically developed children
aged (average age: 35,8± 9,4). Behavioural features of children were investigated by using
the Children Behaviour Check List CBCL/1½-5. The results indicated that in the group
of children with autism spectrum disorder, indicators on the DSM-Pervasive Development
Problems and Withdrawal scales are at a clinical level of severity. Compared with typically
developing children, the ASD sample had significantly high scores for DSM-Pervasive Development Problems, DSM — Affective Problems, DSM — Attention Deficit /Hyperactivity,
DSM Oppositional Defiant Problems scales and syndromes Emotionally Reactive, Somatic
Complaints, Withdrawal, Attention Problems, and Aggressive Behaviour Withdrawal scales.
There was no correlation found between the frequency of exceeding critical indicators of
manifestations in regard to violations of communication with the sex of children, level of
education and marital status of mothers, and the number of children in families in both
groups.

dc.description.abstract

value:
Few existing experimental studies of haptic perception and object exploration in autism address perceptual actions in children with ASD. Haptic perception plays an important role in
the formation of perceptual processes in early childhood. Stereotypical behaviour in children
with ASD and observed sensory abnormalities in different modalities point to the need to
study haptic perception as well. The purpose of this study was to examine haptic perception
in children with ASD and their peers in comparison to their visual perception. 16 typically
developing and 18 children with ASD aged from 6 to 15 years of age participated in this study.
The experiment took place in the context of a game in which children were asked to touch an
object, name it, and draw what they think it is, then the same stimuli were presented in the
visual modality. To register hand movements in a contactless manner for the first time, “Leap
Motion” was implemented. The results indicate that children with ASD have underdeveloped
perceptual actions in the process of haptic perception of the stimuli, which manifested itself in
a lack of contour-following, longer fixations on local components of the figure, which was also
evident in the names and drawings of the stimuli given by children with ASD. The drawings
and names that children with ASD gave to perceived stimuli often included geometric shapes.
Such outcomes provide more proof of general deficits in perception in children with autism.

dc.description.abstract

value:
A number of studies suggest a higher prevalence of suicidal behaviour among body modified
individuals compared to the general population. In order to study tattoo features correlated to
suicidal behaviour, 184 tattooed individuals aged from 18 to 32 were split into three groups:
“ideators” (n=28), “attempters” (n=55) and “no suicidal tendencies” (n=101). The participants
were allocated to groups based on their personal history of suicidal attempts and self-injurious
behaviour and current suicidal ideation. The history of suicidal and self-injurious behaviour
and tattoo features were assessed with a non-standardized self-report questionnaire. Actual suicidal ideation was assessed using Beck’s Hopelessness Scale and Holden’s Psychache Scale. Selfconcept as a possible mediator was assessed using the “Self-concept questionnaire” (V.V.Stolin,
S.R.Pantileev). The data was processed with multinomial and logistic nominative regression. The results suppose that having a tattoo on body areas where tattooing is especially painful and
having a tattoo depicting only words are associated to having committed a non-lethal suicidal
attempt, with the latter fully mediated by its association to systematic self-injury. Results also
suggest that there is no association between (a) suicidal behaviour or self-concept and (b) an aggressive tattoo plot, visibility, or number of tattoos. The results can be used as a component of a
comprehensive suicidal risk assessment model or in clinical assessment of suicidal risk.

dc.description.abstract

value:
The article presents the author’s psychodiagnostics method “Prenatal contact”. The method
can determine the quality of psychological contact between a pregnant woman and her unborn child (children) in the late stages of single and multiple pregnancies. The stages of the
method’s creation are described in the article. Russian and foreign studies, as well as verbal
psychodiagnostic techniques, devoted to a woman’s experiences during pregnancy are analysed. In the process of clinical work, the significance of a child’s movements for women in late
pregnancy was revealed. Prenatal contact was defined as cognitive, affective, and behavioural
activity of women for the purpose of establishing a connection with the unborn child and
interaction with him. It is suggested that in the process of establishing this contact, maternal
qualities begin to develop. These qualities will further influence the quality of interaction between the mother and the infant and, as a result, the quality of the child’s attachment to the
mother. There is sensitivity and responsiveness to the child’s signals, acceptance of the child,
and emotional involvement by being in contact with him. The results of statistical evaluation
in a study of 168 pregnant women with one foetus (99 women) and multiple (69 women),
with a gestation period of 24 to 41 weeks, aged 23 to 43 years and having different prenatal
history are presented. The test’s scales were checked for their reliability. The following names
of scales are suggested: “Interaction with the child (children)”, “Sensitivity to the movements
of the child (children)”, and “Intensity ‘of emotional messages’ to the child (children)”. A detailed description of each scale is provided, the manifestations of a particular result in clinical
psychological practice are described, and the possibilities of using this information to provide
psychological assistance to pregnant women are outlined.

Laws of evolution seem to be relevant not only for biological domains, but for
informational systems. This paper provides a sketch of a comparison of two
systems — that of homeostatic systems, and that of language evolution. We
argue that the patterns of evolution of functions are hierarchically organized
according to four main levels: I — the primary level: a cell in biology, a phoneme
in language; II — functional units: a nephron, a morpheme; III — organs: a kidney (a lung, a heart, etc.), a word; IV — systems: physico-chemical constancy, a
sentence or a phrase. There is a set of restrictions for each domain: the linguistic changes have not occurred in all languages, in many cases they are still underway, there are ‘old’ and ‘young’ languages, etc. Such comparisons appear to
be relevant and can be applied to objects as far removed as these. This allows
us to speak of certain evolutionary universals.

dc.description.abstract

value:
The research aimed to establish an optimal and safe level of mineral nutrition
for buckwheat grown in the fluoride contaminated soil by defining yield and
chemical composition of buckwheat grown on acidic soddy-podzolic soil under
different levels of fertilization, and assessing the possibility of reducing fluoride
phytotoxicity. The mechanisms of plant uptake of fluoride may be influenced
by interaction in nutrient uptake by plant. Sodium fluoride solution was applied at the rate of 100 mg per 1 kg of soil mass. Two different experiments
were studied under controlled conditions: the first experiment with increasing
doses of ammonium nitrate, and the second experiment with increasing doses
of orthophosphoric acid. Increase of N fertilization resulted in an increase in
the concentration of fluoride in the tissues of buckwheat and lowers yields of
plants, while application of P reduced uptake of fluoride and increased productivity of buckwheat. In fluoride contaminated soil the chemical composition of
buckwheat was affected by synergism and antagonism of individual elements
during absorption by plants. A protective mechanism of buckwheat against
negative effect of fluoride was due to its ability to activate metabolism regulating the flow of individual elements in tissue that reduces the adverse impact of
pollutant.

dc.description.abstract

value:
The study of the molecular mechanisms of maintaining the integrity of the epithelium during mechanical stress remains a relevant problem in the physiology
of tissue barriers. A methodical approach has been applied which makes it possible to reproduce mechanical pressure on the apical region of cells in vivo and
to study the participation and role of tight junctions in maintaining the integrity of the epithelial structure. Mammary gland tissue specimens from lactating
control mice and animals after a 20-h interruption of suckling were prepared
and the width of the tight junction of the secretory epithelium was analyzed. At
the ultrastructural level, it was shown that accumulation of milk caused a significant increase in the width of the tight junction between epithelial cells. In the
control group, the width of this structure was 2.1 ± 0.1 µm; in the experimental
group — 4.2 ± 0.1 μm. The marked increase in the width of tight junctions between epithelial cells is in accordance with an observed increase in the level of
claudin-1 and -3 in the secretory epithelium and can be interpreted as adaptive
changes aimed at maintaining the structure of the alveoli.
