dc.description.abstract

value:
The article considers the risks of amendments to the basic law of the state, which are associated
with the inability to accurately predict political and managerial problems arising in the new
constitutional context. An analysis is conducted of the changes in constitutions as the basis of
the political, economic, and social life of the societies that are bifurcation points from which development
can proceed in various directions. This creates risks at the stages of formation and
functioning of complex public systems of authority, whose work greatly influences the creation
of an optimal quality of life as the criterion of the basic goal of a modern democratic state. The
analysis is comprised of factors that affect the reduction or levelling of such risks or increase the
possible of their occurrence. A developed democratic political culture and a high degree of public
readiness for radical changes in the foundations of the political system (for example, France
after World War II) are identified as factors that positively affect the state system, and excessive
haste in decision making and lack of broad public fundamental changes discussion (for example,
Germany in the early 90-ies of the last century) are identified as factors that negatively affect the
social integration of society and the achievement of uniformity in the quality of life on the territory
of the state. Both examples demonstrate in the Russian context the need to balance state policy
in the process of implementing political decisions that led to amendments to the Constitution of
the Russian Federation in 2020.

dc.description.abstract

value:
This article examines the role of popular culture products as a factor in changing the concept
of patriotism in the United States. The discourse of patriotism is formed through a “sum” of images including an assessment of the political system, values and national history. According to
American sociologist Jeffrey Alexander, “gaining power depends on the outcome of struggles for
symbolic domination in the civil sphere”. The exacerbation in the last decade of problems related
to race, gender and social justice led to a split in society and created the demand for a critical
revision of the history of the United States, and as result the revision of the concept of patriotism.
Nowadays, more and more graphic novels and media-shows based on patriotism are focusing on
issues of social justice, and play an important role in the “culture wars” in the United States. An
example of this is the popular series “Watchmen”, which has received various influential awards.
Through the plot about superheroes, its authors construct a new narrative of civic patriotism. This
narrative assumes that the racial issue has been a key factor in US history and that the country
was founded on the principles of intolerance and oppression. In addition, it is suggested that
the political system, in turn, is only formally democratic and the founding fathers created a state
that is prone to authoritarianism and suppression, regardless of which political party is in power.
Therefore, radical reforms are required for the United States to become a truly democratic and
inclusive country.

dc.description.abstract

value:
The article shows that the future is multivariate, the world has become anomalous and entered a
period of global instability and unsteadiness and a new model of civilizational development is being
formed. The choice of future development takes place in the sphere of culture on the basis of
a value conflict, during which the selection of experience worthy of cultural transmission is carried
out. Therefore, the very choice of the future civilizational development is not unambiguous. Values
create a holistic image of a person’s life world, expressing an attitude towards reality. The filling of
existing values with a new content is the result of the rooting of new worldview meanings, which
reflect the state of culture as an environment in the depths of which the synthesis of traditional
and emerging new civilizational experience is constantly taking place. On this path, strategies that
preserve the basic values of the previous type of development compete with innovative aspirations
focused on the search for new life meanings and updating the content of values that meet
modern realities. New values are born in the depths of the old culture and form the shoots of the
future civilization.

dc.description.abstract

value:
Vaccination in light of the COVID-19 pandemic is a hot topic in scientific and popular circles.
The article presents the adaptation and validation of the questionnaire measuring the propensity
to believe in conspiracy theories regarding vaccination (Vaccine Conspiracy Beliefs
Scale). The questionnaire consists of 7 statements with 7 response categories in the Likert
scale. The work includes translation and adaptation for the Russian sample of the Englishlanguage
version of the questionnaire, including forward and backward translation as well as
the use of cognitive laboratories. The translation was carried out by three experts, followed by
the finalization of the questionnaire version for quantitative analysis. The cognitive laboratory
tested how clear the translation and the investigated construct were for respondents. Data
analysis was conducted within the framework of modern testing theory using models from
Rasch modeling. The sample consisted of 308 students from Russian universities (average age 20.6 years; SD = 3.9). The quantitative analysis showed satisfactory psychometric characteristics
of the questionnaire. A deeper analysis revealed that the sample is divided into two latent
classes according to the response style of the test takers. The response style is a specific characteristic
of the test-taker, which makes it possible to closer examine the reasons why the testtaker
has chosen one or another response option. The study of response styles is an underrepresented
area in domestic research and the article contributes to the development of this area
while also emphasizing the need to study response styles when using questionnaires. Overall,
the article details the methodology for validating measurement tools in the social sciences.

dc.description.abstract

The article is aimed at analyzing the behavior of labor migrants from CIS countries who come
to Moscow to earn money and face a significant amount of life difficulties. The theoretical
basis of the research is the theory of the marginal man by Robert Park and the concept of the
stranger by Georg Simmel. The research methodology is based on mixed methods — a combination
of in-depth interviews and a standardized online survey. In the process of the authors’
research, the main situations of life difficulties that represent traumatic experiences for labor
migrants were identified and studied. The main ones are the lack of official employment opportunities,
even if migrants have a higher education and professional skills, as well as negative
stereotypes of Moscow citizens towards migrants, which make it difficult for migrants
to find a place to live and receive temporary registration at the place of residence. As a result
of the analysis, the following main strategies for coping with life’s difficulties were identified:
active search for solutions to problems, search for help among compatriots, professional development
and self-improvement, integration into the host society by attending cultural events.

Assessment of the accuracy of snow water equivalent calculation with the use of global numerical weather prediction models and SnoWE snowpack model (by the example of the Kama River basin). Vestnik of Saint Petersburg University. Earth Sciences, 66 (1), 167–188.

dc.description.abstract

value:
The paper discusses the results of snow cover formation and snowmelt modeling in the Kama
River basin (S = 507 km2) using two approaches previously developed by the authors. The
first one is the SnoWE snowpack model developed at the Hydrometeorological Center of the
Russian Federation and used in quasi-operational mode since 2015, and the second is a GISbased
empirical technique which was previously implemented for the Kama River basin. Both
methods are based on a combination of numerical weather prediction (NWP) models’ data
with operational synoptic observations at the weather stations. The study was performed for
the winter seasons 2018/2019 and 2019/2020. To assess the reliability of simulated snow water
equivalent (SWE), we obtained in-situ data from 68 locations (snow survey routes) distributed
over the entire area of the river basin. As a result of the study, the main advantages and
limitations of the two methods for SWE calculation were identified. As for the maximum
values of SWE, the root mean square error (RMSE) of simulated SWE ranges from 14 to 28 %
of the average observed SWE according to in-situ data. It was found that the SnoWE model
more reliably reproduces SWE in the lowland part of the river basin. Simultaneously, SWE
was substantially underestimated according to the SnoWE model in the northern and mountainous
parts of the basin. The second method provides a more realistic estimate of the spatial
distribution of SWE over the area, as well as a higher accuracy of calculation for the northern
part of the river basin. The main drawback of the method is the substantial overestimation of
the intensity of snowmelt and snow sublimation. Consequently, the accuracy of SWE calculations
sharply decreases in the spring season. SWE calculation accuracy in the winter season
2019/2020 was substantially lower than in 2018/2019 due to frequent thaws.

dc.description.abstract

value:
The purpose of the article is to introduce a fragment of an unpublished monograph by sociologist
and historian Nikolay I. Kareev titled “General methodology of the humanities” (1922).
The book was published only in fragments and needs further updating in terms of its significance
for the history of Russian sociology. In the publication of archival documents and
accompanying annotations, a fragment of the final seventh chapter “Normative and Applied
Knowledge in the Humanities” is analyzed. In this text, the scholar turned to the complex theoretical
issues of defining the role, function and correlation of fundamental and applied sciences.
The text analyzes N. I. Kareev’s classification — the division of scientific knowledge into
theoretical, normative and applied. By carefully examining applied knowledge, he revealed
it in two aspects — vulgar and pragmatic utilitarianism. Regarding the first, he concluded
that the absolutization of the utilitarian point of view is dangerous for science itself, since it
makes the development of science dependent on particular goals, including party interests,
and subordinates science to the changing circumstances of the moment. On the other hand,
theoretical knowledge can also have value as the most reliable basis for any practical discipline.
The importance of applied knowledge is due to the fact that true (factual) knowledge
about society can only be obtained by inductive means, i. e., in order to cognize social reality,
applied sciences must precede theoretical ones. The meaning of applied knowledge is that it,
unlike theoretical knowledge, is aimed at transforming nature or society.

dc.description.abstract

value:
The events of the “Arab spring” and its consequences as well as the “Iranian threat”, which became
a key security challenge for the Gulf States, not without the efforts of Benjamin Netanyahu
and supported by the pro-Israel Trump administration (2016-2020), seemed to have removed
the Palestinian case from the priority list of Middle East issues. The role of Russia, the traditional
partner of the Palestine Liberation Organization (PLO) since Soviet times, also looked more lowkey
after the collapse of the Soviet Empire, especially amid resolution of the military-political crisis
in Syria. Russian diplomacy on the Palestinian track remained unnoticed compared to the activity
in the region of Donald Trump’s envoys, who promoted a peace plan for settling the Palestinian-
Israeli conflict known as the “deal of the century”. Having failed to achieve the main goal, the
White House contributed to the signing of the “The Abraham Accords”, which was a breakthrough
given that the Arab states declared the solution of the Palestinian issue as precondition for formal
relations with the Jewish state. If Arab-Israeli normalization continues, Israel will have peace
treaties with more than half of the Arab and Muslim states despite the deadlock in the peace
process with the Palestinians. Based on the analysis of political processes amid the unresolved
Palestinian problem, and above all, Russia’s attempts as a mediator to achieve a settlement of the
Palestinian-Israeli conflict, the author suggests that the Palestinian issue has not lost its political
significance and relevance as much as the Israeli government under Netanyahu tries to sell it.

value:
Based on the analysis of the results of the scientific research “Ethnopolitical processes in the
Caucasus in the assessments and perceptions of modern youth” (grant RFBR and ANO EISR
No. 19-011-31300), the content and features of the formation of an all-Russian civic identity among
young people in the North Caucasus are reviewed. The purpose of the study is to identify the risk
of conflict in the process of forming the all-Russian identity of youth in the North Caucasus. The
objectives of the study: determination of the ratio of the all-Russian civic, regional, ethnic and
religious identity in the portfolio of identities of the youth in the North Caucasus, the main actors
in the formation of the foundations of the all-Russian identity, the importance of patriotism and
civic engagement for young people, as well as assessing the role of the state in the process of forming
the all-Russian identity. The theoretical and methodological basis of the study is made up of
the main approaches and concepts of understanding the all-Russian civic identity. The empirical
basis is sociological research consisting of assessments and views of young people in the North
Caucasus. For the region, an extremely important task is the formation and development of an
all-Russian civic identity, its integration with ethnic and regional identities in the minds of young
people. Civic, regional, ethnic and religious identity in the minds of young people in the North Caucasus
is in an unstable equilibrium state, which carries the risks of a conflict of identities. There is
a demand among young people for active participation in the socio-political life of the region. The
influence of the state, represented by the education system and state media, on the formation of
the socio-political views of young people in the region is decreasing, and the role of the blogosphere
and social networks is increasing. The state can become a leading actor in the formation of
the all-Russian identity of the region, subject to the creation of a favorable social environment and
the formation of functional feedback mechanisms between the authorities and the region’s youth.

dc.description.abstract

value:
Investment strategies related to the use of high-dividend shares have been known for more
than 30 years. Despite this, they remain relevant today A large number of studies on this topic
are devoted to studying the effectiveness of high-dividend strategies within one market, and
cross-country studies evaluate a small number of markets. The aim of this paper is to evaluate
the effectiveness of high-dividend strategies in the markets of all APEC economies, with the
exception of Brunei and Papua New Guinea. The time horizon of the study is from 2002 to
the present. We applied well-known modifications of the classic high-dividend strategy and
modifications developed by the authors. We test hypotheses regarding the influence of various
factors, such as the number of shares in a portfolio, the month of portfolio formation,
classifying the economy as developed or developing, and the return on high-dividend portfolios.
We also test the hypothesis that the significance of the high-dividend anomaly exists in
various markets, but decreases over time. The results show different levels of effectiveness of
high-dividend strategies and the different impact of the factors on the markets of developed and developing APEC economies. We found that high-dividend strategies are generally more
effective in emerging markets, but in case of market growth, high-dividend strategies increase
their abnormal returns only in developed markets. At the same time, the authors conclude
that the number of shares in a high-dividend portfolio directly affects the result of its work.
The results have theoretical and practical value, and can be applied in compiling a real investment
portfolio.

dc.description.abstract

value:
This critical analysis of Joan Neuberger’s book This Thing of Darkness (Cornell University Press, 2019)
hails the monograph for its exhaustive research and thorough analysis. Eisenstein stands out in the pages of This
Thing of Darkness as the quintessential non-conformist — an exception to everything we know about Soviet subjectivity. Neuberger argues that the question of whether Eisenstein was pro-Soviet or anti-Soviet is effectively
a reductionist dead end. Eisenstein, she suggests, was an exception — someone who defied categorization,
whether by his cinematographer contemporaries or by Stalin himself, for that matter. The article contends that
Neuberger’s reading of Eisenstein as an imaginative, stubborn, risk-taking and subversive director challenges
recent scholarship on the restrictive nature of Stalinist subjectivity. The author also investigates Neuberger’s
contention that Stalin banned the second part of Ivan the Terrible in part because of the film’s homoeroticism
by reexamining the fragmentary historical record. In so far as there is no reason to think that Stalin would have
hesitated to articulate to Zhdanov or to Eisenstein and Cherkasov any specific objections he had to the film’s
homoeroticism, the author suspects that the best explanation for the dictator’s banning of the film remains the
historical license that Eisenstein took with the official Stalinist line on the terrible tsar.

A dynamically symmetric satellite in a circular orbit of small inclination is considered. The
problem of the Lorentzian stabilization of the satellite in the orbital coordinate system in
the indirect equilibrium position is solved under the conditions of the perturbing effect of the
gravitational torque. To solve this problem, which is characterized by incomplete control,
a method of averaging differential equations is developed. Using the original construction
of the unsteady Lyapunov function, we obtain sufficient conditions for the asymptotic
stability of the programmed satellite motion mode in the form of constructive inequalities
with respect to the control parameters.

value:
Monte-Carlo approach towards solving Cauchy problem for large systems of linear differential
equations is being proposed in this paper. Firstly, a quick overlook of previously
obtained results from applying the approach towards Fredholm-type integral equations is
being made. In the main part of the paper, a similar method is being applied towards a
linear system of ODE. It is transformed into an equivalent system of Volterra-type integral
equations, which relaxes certain limitations being present due to necessary conditions for
convergence of majorant series. The following theorems are being stated. Theorem 1 provides
necessary compliance conditions that need to be imposed upon initial and transition
distributions of a required Markov chain, for which an equality between estimate’s expectation
and a desirable vector product would hold. Theorem 2 formulates an equation that
governs estimate’s variance, while theorem 3 states a form for Markov chain parameters that
minimise the variance. Proofs are given, following the statements. A system of linear ODEs
that describe a closed queue made up of ten virtual machines and seven virtual service
hubs is then solved using the proposed approach. Solutions are being obtained both for a
system with constant coefficients and time-variable coefficients, where breakdown intensity
is dependent on t. Comparison is being made between Monte-Carlo and Rungge Kutta
obtained solutions. The results can be found in corresponding tables.

The recurrent equations for filter and its error are delivered. The optimal way of

the algorithm leads to a stationary behavior at infinity. In the other example the Kalman -
Bucy filter is impossible because the filter error goes to infinity. A behavior of a signal and
its error is illustrated by a simulation of a signal and a noise as vector Gaussian stationary
autoregressive processes. The simulation supports theoretical conclusions.

dc.description.abstract

value:
The damped rotational oscillations of a cylinder whose length-to-diameter ratio is nine
are considered. In the head part of the cylinder, a disc is mounted coaxially on the leg.
The effect of the disk on damping oscillations is described by two parameters: the sum of
the rotational derivatives mωz + mθz and the rotational derivative mθz. To determine these
parameters in the aerodynamic tunnel of low speeds, an experiment is performed with the
flow past a cylinder fixed on an elastic spring suspension. In the experiment, the diameter
of the coaxial disk and the distance between the disk and the end of the cylinder varies.
Deflected from the equilibrium position, the cylinder performs damping oscillations. The
tension of one of the springs of suspension is measured using the strain gauge method.
The signal is converted to digital form using the Velleman PCS500A PC oscilloscope and
recorded to a file on the computer. Thus, the frequency of oscillations and the dependence
of the amplitude of oscillations on time are determined. Disks whose diameter exceeds
the diameter of the cylinder do not have a strong effect on the damping of oscillations
of an elastically fixed cylinder. Disks of smaller diameter promote rapid damping of the
oscillations. The presence of a large-diameter disk leads to a decrease in the coefficient mωz.
A small-diameter disk acts in a opposite way.

Lao and Mayer (2008) recently developed the theory of U-max statistics, where instead of
the usual sums over subsets, the maximum of the kernel is considered. Such statistics often
appear in stochastic geometry. Examples include the greatest distance between random
points in a ball, the maximum diameter of a random polygon, the largest scalar product
in a sample of points, etc. Their limit distributions are related to distribution of extreme
values. This is the second article devoted to the study of the generalized perimeter of a
polygon and the limit behavior of the U-max statistics associated with the generalized perimeter. Here we consider the case when the parameter y, arising in the definition of the
generalized perimeter, is greater than 1. The problems that arise in the applied method in
this case are described. The results of theorems on limit behavior in the case of a triangle
are refined.

the form of computational methodology to cope with the network optimization problem.
A uniqueness theorem is proved for a certain type of road network. Explicit relations
between travel demand and traffic flow are obtained for a single-commodity network of
non-intersecting routes with special polynomial travel time functions. The obtained findings

In this paper a study on constructive construction of the generalized normal forms (GNF)

part forms a first degree quasi-homogeneous first degree polynomial (αx21
+ x2, x1x2) of
type (1, 2) where parameter α ∈  2 (−1/2, 0)[(0, 1/2]. For given value of   this polynomial is
a canonical form, that is an element of a class of equivalence relative to quasi-homogeneous
substitutions of zero order into which any first order quasi-homogeneous polynomial of type
(1, 2) is divided in accordance with the chosen structural principles due to it only making
sense to reduce the systems with the various canonical forms in their unperturbed part to
GNF. Based on the constructive method of resonance equations and sets, the resonance
equations are derived. Perturbations of the acquired system satisfies these equations if
an almost identity quasi-homogeneous substitution in the given system is applied. Their
validity guarantees formal equivalence of the systems. Besides, resonance sets of coefficients
are specified that allows to get all possible GNF structures and prove reducibility of the
given system to a GNF with any of specified structures. In addition, some examples of
characteristic GNFs are provided including that with the parameter   leading to appearance
of an additional resonance equation and the second nonzero coefficient of the appropriate

dc.description.abstract

value:
A problem of optimal scheduling is considered for a project that consists of a certain set of
works to be performed under given constraints on the times of start and finish of the works.
As the optimality criterion for scheduling, the maximum deviation of the start time of works
is taken to be minimized. Such problems arise in project management when it is required,
according to technological, organizational, economic or other reasons, to provide, wherever
possible, simultaneous start of all works. The scheduling problem under consideration is
formulated as a constrained minimax optimization problem and then solved using methods
of tropical (idempotent) mathematics which deals with the theory and applications of
semirings with idempotent addition. First, a tropical optimization problem is investigated
defined in terms of a general idempotent semifield (an idempotent semiring with invertible
multiplication), and a complete analytical solution of the problem is derived. The result
obtained is then applied to find a direct solution of the scheduling problem in a compact
vector form ready for further analysis of solutions and straightforward computations. As
an illustration, a numerical example of solving optimal scheduling problem is given for a
project that consists of four works.

dc.description.abstract

value:
In this paper, a second-order discrete-time automatic control system is studied. This work is
a continuation of the research presented in the author’s papers “On the Aizerman problem:
coefficient conditions for the existence of a four-period cycle in a second-order discrete-time
system” and “On the Aizerman problem: coefficient conditions for the existence of threeand
six-period cycles in a second-order discrete-time system”, where systems with two- and
three-periodic nonlinearities lying in the Hurwitz angle were considered. The systems with
nonlinearities subjected to stronger constraints are discussed in this paper. It is assumed
that the nonlinearity not only lies in the Hurwitz angle, but also satisfies the additional
sector-condition. This formulation of the problem is found in many works devoted to theoretical
and applied questions of the automatic control theory. In this paper, a system with
such nonlinearity is explored for all possible values of the parameters. It is shown that in
this case there are parameter values for which a system with a two-periodic nonlinearity
has a family of four-period cycles, and a system with a three-periodic nonlinearity has a
family of three- or six-period cycles. The conditions on the parameters under which the
system can have a family of periodic solutions are written out explicitly. The proofs of the
theorems provide a method for constructing nonlinearity in such a way that any solution
of the system with initial data lying on some definite ray is periodic.

The article is dedicated to some generalizations of the classical optimal choice problem (the

distributed random variables on the interval [0, 1]. Getting consistently observed values
of these variables, we should stop at some moment on one of them, accepting it as the
initial point for counting upper or lower record values. In the optimal choice problem and
its generalizations, it is needed to make the correct choice of the initial point of counting
records, in order to guess the place of the last record (the classical optimal choice problem)
or to maximize the expected sum of upper and/or lower record values or the expected total
number of upper and/or lower records, obtained by this procedure. A review of results
on the uniform distribution of the random variables and some new results concerning the
exponential distribution are presented.

dc.description.abstract

value:
The problem of obtaining sufficient conditions for the asymptotic stability for a certain
class of linear systems of a neutral type with constant delay is analyzed in the article. Some
coefficients of these systems in the right side have an exponential factor. As a consequence, the
study of the stability of such systems with the help of the Lyapunov—Krasovskii functionals is not possible; methods of receiving asymptotic appreciations lead to extremely rough results.
By applying the apparatus of difference systems and the properties of simpler systems,
which the author examined previous, sufficient conditions for the exponential stability of
such systems are obtained. As an example, a second-order system is considered. The graphs
of the solutions of the corresponding system, both without neutral members and with the
original system where the right-hand side contains neutral terms, are provided. On the basis
of theory difference systems, the author proposes an algorithm of stabilization for some
systems of a similar type.

The article considers the problem of optimal control of an object described by a linear

bounded controls that lie in some parallelepiped at each moment of time are admissible. The
standard discretization of the original system and the control parametrization are used,
some convergence theorems of the discrete problem solution to the continuous problem
solution are presented. Further, for the obtained discrete system, the necessary and sufficient
minimum conditions are written out in terms of the codifferential, the method of the modified
codifferential descent is applied to it, which guarantees to find the global minimum of this
problem in a finite number of steps. The proposed algorithm is illustrated with examples.

dc.description.abstract

value:
The article analyzes a linear mechanical system with a large parameter at the vector of
velocity forces and a distributed delay in positional forces. With the aid of the decomposition
method, conditions are obtained under which the problem of stability analysis of the original
system of the second-order differential equations can be reduced to studying the stability of
two auxiliary first-order subsystems. It should be noted that one of the auxiliary subsystems
does not contain a delay, whereas for the second subsystem containing a distributed delay,
the stability conditions are formulated in terms of the feasibility of systems of linear matrix
inequalities. To substantiate this decomposition, the Lyapunov direct method is used. Special
constructions of Lyapunov—Krasovskii functionals are proposed. The developed approach is
applied to the problem of monoaxial stabilization of a rigid body. The results of a numerical
simulation are presented confirming the conclusions obtained analytically.

Results of numerical studies of the influence of reinforcement orientation of hard layers and

of the eigenmodes of the coupled vibration modes, if at least one of its own forms in plate
directions is characterized by an even number quarters of a wave, and another proper
form   an odd number of quarters the waves. In an unsymmetrical asymmetric three-layer
plate, bending-bending interaction arises, generating mutual transformations eigenmodes
of coupled vibration modes in two mutually orthogonal planes if in the main directions
of the plate both of their own forms characterized by either an even or an odd number
of quarters of a wave. It was found that each mode of natural vibrations of three-layer plates corresponds to the effective relative thickness of the soft isotropic layer viscoelastic
polymer.

dc.description.abstract

value:
We obtain a new version of Hardy theorem about power series of several variables reciprocal
to the power series with positive coefficients. We prove that if the sequence
{as} = as1,s2,...,sn, ||s|| ≥ K satisfies condition of logarithmically convexity and the first
coefficient a0 is sufficiently large then reciprocal power series has only negative coefficients
{bs} = bs1,s2,...,sn, except b0,0,...,0 for any K. The classical Hardy theorem corresponds to
the case K = 0, n = 1. Such results are useful in Nevanlinna - Pick theory. For example, if
function k(x, y) can be represented as power series Pn≥0 an(x¯y)n, an > 0, and reciprocal
function 1
k(x,y) can be represented as power series Pn≥0 bn(x¯y)n such that bn < 0, n > 0,
then k(x, y) is a reproducing kernel function for some Hilbert space of analytic functions
in the unit disc D with Nevanlinna-Pick property. The reproducing kernel 1
1−x¯y of the
classical Hardy space H2(D) is a prime example for our theorems.

dc.description.abstract

value:
In the article it is shown that the nanopatterned interface of bimaterial is unstable due
to the diffusion atom flux along the interface. The main goal of the research is to analyze the
conditions of interface stability. The authors developed a model coupling thermodynamics
and solid mechanics frameworks. In accordance with the Gurtin—Murdoch theory of
surface/interface elasticity, the interphase between two materials is considered as a negligibly
thin layer with the elastic properties differing from those of the bulk materials. The growth
rate of interface roughness depends on the variation of the chemical potential at the curved
interface, which is a function of interface and bulk stresses. The stress distribution along
the interface is found from the solution of plane elasticity problem taking into account plane
strain conditions. Following this, the linearized evolution equation is derived, which describes
the amplitude change of interface perturbation with time.

C. Jacobi found that in the General N-Body-Problem (including N = 3) for the Lagrangian
stability of any solution necessary is the negativity of the total energy of the system. For the
restricted three-body-problem, this statement is trivial, since a zero-mass body introduces
zero contribution to the energy of the system. If we consider only the equations describing
the movement of the zero mass point, then the energy integral disappears. However, if we
average the equations over the longitudes of the main bodies, the energy integral appears
again. Is the Jacobi theorem valid in this case? It turned out not. For arbutrary large values
of total energy, there exist bounded periodic orbits. At the same time the negative energy
is sufficient for the boundedness of an orbit in the configuration space.

dc.description.abstract

value:
The Western philosophical and scientific tradition was and still is based on rationalism, objectivity,
truths that are all sought from the ocularcentric paradigm. Many thinkers, however, have been recognising
this perspective to be exclusive towards the other senses, and therefore insufficient. Listening, as
enabled by the auditory sense, has a potential for revealing a deeper sense of being in the world. In this
article listening is presented as a possible way towards inhabiting our life-world and nonetheless “to let
things be.” In order to do so, an interdisciplinary approach of research is adopted. First, the author offers
some perspectives from the field of the ethics of listening, where the thoughts of Lisbeth Lipari, Luce
Irigaray and others expose listening as an intersubjective gesture of encounter with the other in acceptance.
Through his philosophy of listening, Jean-Luc Nancy, one of the crucial voices in this study, offers
an explication of how listening can be the force of liberating sense and senses. Further on, an account on
auditory phenomenology is offered, combining it with and stressing the importance of Husserl’s under standing of intersubjectivity. These perspectives are then enriched with echoes from acoustic ecology
and its experiences of listening to the environment. The reverberations of multiple voices presented in
this text allow for an understanding of listening as an intersubjective and mutually constitutive activity.
As such, it involves a liberation of sense and allows for an openness to being and beings.

dc.description.abstract

value:
The secularized and rational-oriented mindset of the Western civilization does not preclude important
elements of a religious worldview. The objective of the present study is to come to understand the
role the categories of Being and God play in the present day spiritual situation. Heidegger’s and Rahner’s
views are considered here within the prospective of the paradigmatic process. The latter marks the
fading away of the classical understanding of God and search for new and divine meanings. Therefore
I suggest considering some of the most significant motifs in the two philosophers’ reflection as regards
the history of western civilization and our epoch in the context of the categories of God and Being.
Among these motifs there are such attitudes as subjectivism, self-suggestion, disposal of beings, planetarism,
oblivion of Being, loss of origins, groundlessness, alienation, situation of meaninglessness. It
is due to these attitudes, especially owing to meaninglessness, that many people tend to raise again the
issue of the concealed, the encompassing, God or Being. Or perhaps speaking about “Being” and “God” can be interpreted as something that leads to the oblivion of Being and to atheism. “Being” in Heidegger
and “God” in Rahner single out the existential centre to which forms of life are related. Nowadays it
is forgotten or even vanishes. “God” or “Being” hold everything together and confer meaning thereto.
Could it be exactly what modern man is in search of? One has to find answers to these questions.

The collective volume Early Phenomenology in Central and Eastern Europe: Main Figures, Ideas, and
Problems, edited by Witold Płotka and Patrick Eldridge, enriches the ongoing and highly topical research
of the history of phenomenology with the thematization of a specific period and localization
of phenomenology. The authors of eleven chapters explore the emergence of phenomenology in local
traditions outside the Germanophone area, its appropriation and development, describing the unique
forms it acquired in individual environments. The book clarifies the characteristics of the early wave
of phenomenology and provides a list of Central and Eastern European phenomenologists who participated
in it. On the one hand, the volume is a contribution to historiography, enriching the study
of the history of phenomenology thematically and thus contributing to the development of phenomenology
itself; on the other hand, it introduces its own set of philosophical problems. These concern
methodology and the issue of the Central and Eastern European identity, which is examined through
the prism of the development of local traditions of phenomenology. When exploring the latter it is
useful to introduce the concept of the marginocentric. This concept, which originated in comparative
literature, facilitates an understanding of the unique cultural configuration of a concrete tradition in its
communication with internal and external environments.

The article treats Ludwig Wittgenstein’s manuscripts and typescripts where he formulates the problem
of impossibility of “phenomenological language” defined by him as the “description of immediate sensual
perception without any hypothetical supplementation.” One may find this phase of his philosophy
(1929–1933) a bit paradoxical because the philosopher claims this phase, from the very beginning,
to have been overcome; we deal here with philosophical self-criticism. The Lewis Carroll’s paradox is
considered in terms of analogy to this criticized project of “phenomenological language”—the paradox
of a ridiculously exact map which coincides with the mapped area. We open up new possibilities for
comparison between the Wittgensteinian project of the “primal language” and Husserlian, Heideggerian
and Finkian projects of “phenomenological language.”

dc.description.abstract

value:
Temporality is one of the key components of our experience, but the experience of time is hardly one
and the same for all of us throughout our lives. The experience of time in its entirety is not solid and
simple. It is a fluid and complex phenomenon consisting of a multitude of dimensions. In medical
phenomenology and phenomenological psychopathology there are ample cases of different temporal
experiences analysed in the context of the illness experience. However, only a few attempts have been
made to propose a conceptual framework that could not only be used to conduct a concrete analysis in
a more systematic manner, but also provide a solid and comprehensive theoretical basis. The aim of this
article is to draw on the rich distinctions found in Husserl’s phenomenology to outline a framework of
different temporal dimensions for the analysis of temporal experience. The framework could provide
conceptual tools to analyse temporal experiences in any field of study that deals with the human experience,
including medical phenomenology and phenomenological psychopathology. The resulting
analysis would be not only clearer, more comprehensive and precise, but also more systematic and conceptually
consistent. The framework consists of fourteen dimensions of temporal experience ordered
in seven binary distinctions: (1) change and structure, (2) immanence and transcendence, (3) ownness
and intersubjectivity, (4) passivity and activity, (5) receptivity and spontaneity, (6) presentation and
representation, (7) unthematized temporality and thematized temporality.

dc.description.abstract

value:
According to Merleau-Ponty in his Phenomenology of Perception, we experience time as a “field of
presence.” In his words, “It is in my ‘field of presence’ in the widest sense […] that I make contact with
time, and learn to know its course.” This field is fundamental. It elucidates my spatial apprehension. In
his words: “Perception provides me with a ‘field of presence’ in the broad sense, extending in two dimensions:
the here-there dimension and the past-present-future dimension. The second elucidates the
first.” In other words, I understand the spatial “here-there” dimension in terms of the temporal dimension.
The “there” is what I immediately grasp in still having in hand “the immediate past.” In this article,
I propose to examine the general conception of time as a field of presence. This examination can be
seen as a kind of “thought experiment,” where we see what happens when we reverse this relation—i.e.,
when we elucidate the “past-present-future dimension” in terms of the “here-there dimension.” Such
a reversal, I will argue, brings to the fore the pragmatic, spatial character of lived time. Not only does
it bring about a revision of horizonal structure of the field of presence, it also has consequences for
psycho-analytical research.

dc.description.abstract

value:
The paper intends to supplement the studies of emotional affordances of BAA by elaborating on the
conception of participatory sense-making as well as developmental studies on joint attention and interattentionality.
I address different spheres of expertise from the experience-based phenomenological
perspective, which allows exploring the problem both from the first-person and second-person perspectives.
This research presents the conception of inter-selfness that carries on M. Merleau-Ponty’s
idea of intercorporeality, T. Fuchs’ et al. analysis of intersubjectivity and phenomenologically oriented
psychoanalysis by E. Z. Tronick et al., R. Stolorow et al. The mechanism of BAA is presented through
the conception of participatory sense-making and the idea of minimal inter-attentionality in developmental
studies. The paper presents an emotional affordances scheme that illustrates the emotional
regulation of BAA. By examining this process of regulation one could see in what way the self becomes
an inter-self in communication. The article also postulates correlation between cultural mediation of
emotional affordances and their direct accessibility from the second-person perspective. In the last part
of the paper, I examine social interaction from the viewpoint of developmental studies (C. Trevarthen,
V. Reddy, M. Carpenter). The developmental perspective supplements the idea of emotional regulation
in interaction, by focusing on primary such forms of BAA between a caregiver and a baby, as joint
attention and mutual gaze. Herein, I demonstrate how the initial forms of the positive bodily-affective
attunement develop into the interattentionality and self-representation practices of the subject. This
point could contribute to the theory of personal identity by exploring the process of maturing of the
sense of self in its different aspects. The results of the research could be useful for further study of BAA and its pathologies. The results could also be of use for the discussion on non-human or human-like
affordance-based technological interaction theory.

dc.description.abstract

value:
Book review focuses on two books by Gunther Neumann, dedicated to the thought of Heidegger and
Leibniz. If one of the books deals specifically with the understanding of freedom in both of the two philosophers,
then the other one deals more with Heidegger’s three approaches to Leibniz’s thought: (1) Interpretation
of Leibniz in the context of the making of fundamental ontology and in Being and Time, as
well as the reading of Leibniz after Being and Time; (2) Interpretation of Leibniz during the transition to
Ereignis thought; (3) Interpetation of Leibniz in the framework of Ereignis thought. Author’s scrupulous
close reading approach allows to show the changes in Heidegger’s approach to Leibniz’s philosophy, as well
as sketch out the placement of Leibniz’s great themes on the horizon of Heidegger’s history of the truth of
being. Author also shows that from metaphysics there stems a certain view in the modern philosophical
discussions oriented on neurosciences—a certain view on the human being and on the freedom of will.
On this background Heidegger appears as a thinker who has looked beyond the alloy of metaphysics and
sciences, in which the concept of freedom has been greatly restricted. Heidegger manages (thanks to the
radical questioning of Being) to turn the view on the problem of freedom, which appears in G. Neumann’s
books as the main problem of philosophy—through the contact of Leibniz’s thought and Heidegger’s.

dc.description.abstract

value:
The paper presents a non-standard interpretation of the celebrated Heideggerian existential das Man
in terms of its oft-underrated unity with Dasein—an entity of a special ontic-ontological prerogative.
The present authors intend to highlight this essential theme in terms of the specific unity of Dasein
being-in-the world, covering many subsequent and adjacent existentials in the analytics of the Heideggerian
existential hermeneutics, especially Mitsein/Mitdasein. Dasein’s existence-essence is based on
the structure of possibilities, and hence free, spontaneous choices, while Das Man is a concrete choice
of a certain modus of existence rendering—as it were—all other modi invalid and non-operational.
Although Heidegger is far from taking up an ethical or moral stance in its traditional understanding,
he is quite adamant that the phenomenon of das Man invalidates a truly human project of existing one’s
own possibilities—to wit—be oneself (Jemeines).

dc.description.abstract

value:
Looking over a hundred years, it should be acknowledged that phenomenological studies in Latvia were
initially carried out in the twenties and thirties of the 20th century, starting with 1) Husserl’s studies and
criticism of solipsism (T. Celms), 2) phenomenological analysis of forms of community (K. Stavenhagen),
and 3) development of cognitive phenomenology in Ladusāns’ many-sided gnoseology. It was not
possible to work on phenomenology during the harsher years of the Soviet regime (1945–1970), but in
the mid-1970s, a phenomenological circle emerged in Riga under the influence of Nelly Motroshilova
and Merab Mamardashvili. Its focus was on the issues of consciousness and language, on phenomenological
ontology, communication, time-consciousness. Since 1990, phenomenological studies have
been expanding, four international conferences have been held in Latvia in cooperation with the World
Phenomenology Institute, nine monographs on phenomenology have been published, and 56 articles
from Latvia have been published in Analecta Husserliana. Themes of papers and presentations included
historicity, space and time, passions, teleology, educational philosophy, aesthetics. Since 2005, nine phenomenology-related doctoral theses have been defended in Riga. Over the last decade, greater
focus has been given to applied phenomenology, its relationships with medicine, social media, violence
research. Phenomenologists influenced a transformation of classical philosophy towards wider
horizons and reflected the necessity to consider concepts of life, nature, body, we-consciousness, it also
opened the way for contemporary perspective dialogue with cognitive sciences, linguistics, identity
studies and psychoanalysis.

dc.description.abstract

value:
How are we to responsively belong to tradition? This paper retrieves the concept of self-tradition
(Sichüberlieferung) in Heidegger’s magnum opus Being and Time (1927). We will take as a guiding
light Heidegger’s designation of a mode of his phenomenology as “phenomenology of the inapparent”
expressed in the 1973 Zähringen Seminar. We will pay special heed to the function of the middle voice,
neutrality of Da-sein, and tautology in the question of Being and history and bring to light the relation
between authentic temporality and authentic historicity in a tautological turning of the selfsame. We
will make a remark on the delay of Da-sein’s authentic historicity in the light of the “self-tradition”
which marks Heidegger’s non-metaphysical response to the heritage of metaphysics of presence. In
the wake of the phenomenology of the inapparent, we will turn to Derrida’s 2008 text The Animal that
Therefore I Am to explore Derrida’s different approach to free the “I am” from that of Heidegger’s Dasein
whose being is set in Jeweilig-Jemeinigkeit. We will show how Derrida’s invention of animot enables
him and us to speak with the voices of our non-human animal others and enables us to free ourselves
from the fixities of presence of the present in our thought, language, and sensitivity. In a relay of the two
philosophers’ reading of us and their ways of self-overcoming of man as rational animal, we will learn
to be in question and to learn to relate to one another without reducing one to the other and other to
the one.

value:
Although Heidegger’s explicit account of “poetic dwelling” belongs to his later philosophy, there are
important indications that he was already engaging with the core matter of the notion in his early
thought. Contrary to the idea that in Being and Time, “dwelling” amounts to mere practical coping
with the environment, we would like to demonstrate that the notion is already a poetic issue in his early
thought, as it requires the appropriation of our relation to the world via an authentic experience of finitude.
Following a topological mode of thinking, the paper thematizes the connections between Heidegger’s
early and later thought, and elucidates the following three points: First, “freeing” and “letting”
appears as the appropriate ethos of a poetic experience of finitude, one that maintains the “clearing” of
meaningfulness. Second, a topological reading of Being and Time can explicate the notions of authenticity
and inauthenticity as different disclosures of the clearing where human being-world correlation
occurs. Third, the notion of “keeping-still” (Schweigen) can be interpreted as an authentic disposition that frees space for the disclosure of existence. The paper concludes that an authentic experience of
finitude through “stillness” appears to reorient human ethos by releasing “discourse” from absorption
in “idle-talk” and that such an act of existential re-orientation of one’s disposition towards the world is
the essence of “authenticity,” and Heidegger’s early “poetic dwelling”.

value:
With this article I offer a close reading of Gadamer’s Aesthetics and Hermeneutics. The reason I draw
attention to this essay is as a response to criticism aimed at Gadamer’s hermeneutic account of art. In
its reception, it has occasionally been viewed as too hermeneutical, too focused on understanding. I
maintain that Aesthetics and Hermeneutics can be considered exempt from this critique. Here, Gadamer
offers us the hermeneutic experience in its most aesthetic guise: in being struck by the significance
of the artwork. The main purpose of this article is to clarify this experience. This task I undertake in
two steps. First, I emphasize the aesthetic nature of this experience of “being struck” by the artwork in
an answer to Figal’s critique. As a supplement to Gadamer’s theoretical remarks in Aesthetics and Hermeneutics,
I consider the performance piece Faust by Anne Imhof. The second step of my argument
intends to show that Gadamer does not “reduce” the aesthetic experience to a hermeneutic experience
of meaning but grounds the experience of art hermeneutically. I will argue for my thesis by closely reconstructing
Gadamer’s argument in Aesthetics and Hermeneutics. The guiding question is, what is the
significance of this aesthetic experience for Gadamer’s hermeneutics? Gadamer conceptually clarifies
the experience of “being struck” in terms of the notion of contemporaneity. In my interpretation, the
experience of art shakes us with a sense of self-implication.

value:
The concept of norms within philosophical texts is an ambiguous phenomenon. On the one hand, it
could be viewed as a certain mode of perception, but on the other hand, norms themselves are an object
of thought. Viewed from the phenomenological perspective norms determine the potential appearance
of the object of perception. The aim of this article is to emphasize the role of norms as a medium
and from the perspective of phenomenology. To do this, the article answers three questions; firstly, the
question about the application of phenomenology (more specifically Interpretative Phenomenological
Analysis (IPA)) in the analysis of social media perception, secondly, the question about the separation
of subjective experience from lived experience. This distinction is essential in the context of the study
to understand what kind of descriptive forms can be expected from this type of study. Thirdly, the relationship
between norms and normality and their presentation on social media is considered. In this
context, norms appear as a medium. The article is based on the research project “Philosophical Analysis
of Information Perception in Social Media.” In discussing norms as a medium, the article pays significant
attention to theoretical evaluation of the method. When confronted with everyday experience it
emerges as a multi-layered phenomenon that holds various contradictions, and in trying to understand
them attention must be paid to the problem of thought-forming. Norms as a medium are understood in
comparison with language. Language obscures itself in being there, but the moment it is studied it disappears
into the abstraction of the word “language.” Norms, on the one hand, are presented as an object
of reflection, but at the same time its’ form and boundaries of presentation are determined by the norms
themselves. Norms are like a medium, like a screen through which what is happening is perceived.
