dc.description.abstract

value:
Russian firms suffer from the negative country of origin effect and legitimacy shortage. This
paper has the aim to reveal factors for Russian firms to focus on while build legitimacy both at
home and abroad. To identify the existing research directions, the 48 articles applying legitimacy and Russian focus from journals in management and business for all years were analyzed,
using both the bibliometric analysis and manual in-depth study of papers. Based on the
specificity of the Russian context and literature analysis about the factors of the legitimacy
concept, we develop a theoretical framework that is supported by a set of propositions about
possible legitimization strategies of Russian firms. Three main pillars of the organizational legitimacy construct such as moral, pragmatic and cognitive, which are accepted as the most
influential ones, were introduced and proposed for Russian firms how to gain them at home
and abroad. This paper has the value for both theory and practice. It contributes to the legitimacy literature, responding to many calls to study the microfoundations of the organizational
legitimacy and developing the holistic theoretical framework within the Russian context. The
findings also are of practical importance for managers and entrepreneurs whose attention is
paid to the effective strategic management and legitimacy building both at home and abroad.

Motivating the working population to master digital skills is an important condition for the
digital transformation of the Russian economy and companies. The article examines the relationship between the general level of motivation for learning digital skills and a number of factors,
assesses the average level of motivation for four groups of skills, and compares the level of motivation between groups of workers and their motives. Empirical data were obtained by conducting
an online survey of the working population in March 2020, the target sample was 116 respondents.
It was revealed that the general level of motivation of workers to learn decreases with the increasing complexity of digital skills. The hypotheses about the relationship between the level of motivation and the perceived difficulty of using information and communication technologies and
previous learning experience were confirmed. Differences between the groups of workers in the
level of motivation and the degree of mastering specialized digital skills, related to the nature of
the work were revealed. A higher interest in mastering this group of skills, as well as the degree
of mastering them, was demonstrated by the group of managers. The strongest motive for acquiring digital skills is the need to use them at work.

dc.description.abstract

value:
The Irkutsk Coal Basin is located in the south of the Siberian Platform. The deposits of the
basin are represented by Jurassic continental sediments. Since the 1970s, tuffs and tuffaceous
rocks have been found in sediments of the Irkutsk Coal Basin, but so far only fragmentary
information has been available on them. Previously, the age of sediments in the Irkutsk Basin
was determined by the biostratigraphic method. We studied a section of the Cheremkhovo
Fm., the most ancient formation of the basin, at the Azeisk coal deposit (in the area of the
town of Tulun) with the aim of obtaining a geochronological constraints on the timing of
sedimentation. The paper shows that tonsteins, which are transformed to clay ash-fall layers
within coals, are suitable for radioisotope dating by accessory zircons. U-Pb dating of accessory zircons in tonstein from an industrial coal seam was performed using the LA-ICP-MS
method. The obtained U-Pb age of 187.44 +0.45 –1.60 Ma, falling into the Pliensbachian Age,
indicates the period of maximum coal formation in the Irkutsk Basin. This is the first radiometric age determination for the timing of accumulation of coal in the Irkutsk Basin. In the
context of paleogeographic reconstructions, this age determines the upper limit of the tectonic
quiescence period, which created conditions for lacustrine-boggy sedimentation in the vast
territory of the Irkutsk Basin.

dc.description.abstract

value:
In Second Temple Judaism, especially in apocalyptic literature, the encounter between
God and believers acquires a distinct visionary accent. Regardless of whether heavenly realities are revealed on earth or the visionary ascends to heaven, the essence is the
manifestation of important revelations. Corresponding Old Testament heroes, such
as Enoch or Moses, according to apocryphal, Samaritan or rabbinic texts, ascended to
the place of God’s presence (a throne room or even a cloud). In addition to receiving
relevant soteriological and cosmological knowledge, they underwent transfiguration
there. The transfiguration of these characters is very illustrative: they take angelic,
royal, and priestly qualities. Divine radiance, shining faces, and magnificent robes are
just some examples of the divine characteristics that are acquired. This article, together with the study of these elements, underlines the fact that these divine qualities were
described in the literature around the change of era and dedicated to Adam prior to
his expulsion from Eden. The closeness between the first man and God in the Garden
of Eden was expressed in a number of divine attributes inherent in Adam, the same
ones that would later be assumed by Enoch or Moses, among others, in heaven. In this
way, the transfiguration of Enoch or Moses is nothing more than a manifestation of
the rich Jewish anthropology of an Adamic character.

A conversation with the famous Russian biblical scholar Mikhail Seleznev is devoted to the modern humanitarian discipline of biblical studies. The conversation
examines the origins of this scientific discipline, its formation and development, internal structure, its connection with other humanitarian disciplines, as well as with
theology understood as a reflection of believers on the foundations of their faith.
Examples of the achievements in biblical studies in the 19th and 20th centuries are
provided, which as a result have changed our understanding of the origin of biblical
texts and the context in which they were created. The article analyzes the attitude
towards scientific study of the Bible in various Christian confessions, in particular, the perception of biblical studies in the Orthodox community and the related
problems of modern church consciousness. The current state and the prospects of
development of biblical studies in Russia are reported on in the article. The issue of
the so-called “intertestamental studies” and its significance for comprehending early Christianity is discussed, as well as that of biblical exegesis from the point of view
of its understanding in modern science and church tradition. Bibliographic recommendations are provided for those who wish to begin a more detailed acquaintance
with modern biblical studies.

dc.description.abstract

value:
The article problematizes the search for the principles to create and implement the
educational program in theology at the university, taking into account the specifics
of the Eastern Christian theological tradition. The need for integrative and sociallyoriented approaches that allow students to authentically perceive the essence of Orthodox theology, expressed in the unity of Eastern Christian speculation and moral
attitude towards life, is substantiated. Taking into consideration the synergistic nature
of theological knowledge and its value-worldview capabilities, the author identifies a
number of fundamental theoretical and methodological approaches for the development of the educational program and the corresponding goals of its implementation.
The formation of a personal value-semantic conceptual system of a young person as a
“super-task” is emphasized. Developing personal meanings with a focus on values, as
they are presented in the Holy Scriptures and the patristic heritage, is a great pedagogical task, which should include the methodology of the so-called “existential cognition,” orienting a person to coexistence and one’s spiritual foundations. The author
illustrates that in theological education, the information-cognitive approach, even
with all its innovations, must be supplemented by an appeal to the issue of personal
coexistence. Many years of the author’s practical experience in the field of education
made it possible to identify a number of pedagogical conditions for such conjugation
presented in the subject-semantic model of pedagogical integration of knowledge.

dc.description.abstract

value:
The article discusses the features of the emergence and spread of sectarian organizations and Old Believer communities in the Azov region in the 19th century.
It is shown that the processes of the spread of sectarian organizations century
were very active, which is explained by the fact that sectarian organizations had a
broad social base and expanded dynamically, despite restrictions from the official
government. The laws in force at that time limited the activities carried out by the
Russian Orthodox Church in counteracting the process of promoting sectarian
teachings at that time. The article illustrates that some of the representatives of
sectarianism disguised themselves as Orthodox and compactly lived within the
boundaries of church parishes. Proselytizing sectarianism was especially active
in the territory of the Yekaterinoslav province by organizations such as the Molokans, Khlysts, Skoptsy, Old Believers, and others. This article characterizes the
prevailing political and legal conditions for the spread of the sects, as well as the
features of the system of religious relations that have developed in the region. On
the basis of archival data, the number of such sects as the Molokans, the Whips,
the Old Believers and the Evangelists, etc., was studied. The specificity of religious
relations between representatives of different religious groups in the Azov region
is analyzed within the framework of a unique phenomenon — a polymodel system of the interfaith relations.

dc.description.abstract

value:
The article considers the conception of a lie established in the work of Nikolai
Berdyaev during the first half of the 20th century. The socially organized lie was at
the center Berdyaev’s attention. In the middle of the 20th century, new theoretical
perceptions of necessity, legality and even value of a lie emerge. A lie is declared
to be a norm of European culture, an inevitable component of economic, political and scientific practice, an essential component of people’s ordinary and family
life. Criticizing these ideas, Berdyaev puts forward a number of counterarguments
relevant both during his time and at the beginning of the 21st century, which makes
this article significant. The fundamental originality of the study of a lie by the Russian philosopher consists in changing the main cause of the phenomenon, from
the personal moral and psychological characteristics of a person to the ontological cause. Berdyaev creates a philosophical-religious theory of “Tragic theodicy”,
where he links the origin of the free will of a person (including the freedom to lie)
with the peculiarities of the origin of Space from two sources. These sources are the
will of God and from voluntary consent to become the existence of some primordium — “Meon (abyss)”, “Abyss”, “Baselessness”: human free will is not a gift from
God. A person’s freedom to act comes before the act itself, its roots are in Meon. For
this reason, it is impossible to make God responsible for cosmic disasters and for
the irrational destructive behavior of man. God is all-merciful, but not almighty,
and He cannot prevent the negative consequences of a person’s free will. A lie on
a worldwide scale is “a lie of the world”, which produces horrendous consequences
and creates “a false existence”, it is related to Meon and it is produced by people. The
article is intended to attract the attention of the scientific community to the creative
heritage of Nikolai Berdyaev.

dc.description.abstract

value:
The article analyses the so-called religious and non-religious fundamentalism. From
an empirical perspective, fundamentalism appears to be a constant phenomenon of
modern life. The author claims that the principle possibility of fundamentalism has
its roots in the sociocultural structures of Modernity. Of course, fundamentalist
positions do not emerge necessarily, but they are inscribed in these structures as a
permanent option. In the field of identity construction, the relation between fundamentalism and modern life can be explored especially well. This is because under
modern conditions identity formation processes have not only found new opportunities, but also risky challenges. Herein lays a significant motive for fundamentalist
identity constructions. To shed some light on this problematic complex, the author
refers to insights of classical social psychology (Dilthey, Mead, Hofstätter, Goffman,
Krappmann) and applies them to the problem here at stake. Because of the close
nexus between fundamentalism and religion, religion plays an important role in
the author’s argument. Reasoning from a protestant theological point of view, the
author is not limited to a descriptive approach, but also offers a normative critique. Translation from German is made by Anna Briskina-Müller.

dc.description.abstract

value:
The article analyzes the relationship between the Anglican and Russian Orthodox
churches at the very end of the 19th century. The reasons why the Anglican — Orthodox dialogue received intensive development and significant theological content during this period are considered. Significant attention is paid to the mutual visits of the
hierarchs of the two Churches, during which they discussed and agreed on numerous
issues related to the rapprochement of the Anglican and Russian Orthodox Churches
in connection with the prospect of planned interfaith unity. Emphasis is placed on the
problem of recognizing the legitimacy of Anglican ordinations, which arose both due
to the historical formation of Anglicanism and in connection with the peculiarities of
the Anglican doctrine of the sacraments, particularly the sacrament of the priesthood.
The author investigates the reasons why Russian theologians, who have carefully studied the historical, canonical and dogmatic sides of the issue, were forced at this stage to
deny the Anglicans the recognition of the legality of their ordinations. In connection
with this decision, the prospect of inter-church unity was postponed indefinitely so
that Anglican theological thought could finally be defined in the sacramentology of
the Anglican creed. At the same time, the dialogue between the two churches was not
interrupted, but rather continued fruitfully in the 20th century.

dc.description.abstract

value:
The article is devoted to Hervaeus Natalis, also known as Hervaeus drom Nedellec,
who was an outstanding theologian at the end of 13th — beginning of 14th centuries
(c. 1260–1323). Brief biographical information about Hervaeus is provided and his
importance for medieval thought is emphasized. The subject matter of the article is
the consideration of a formal difference, or formal distinction in God. The introduction of this concept is usually associated with the name of Duns Scotus, and there is
every reason for this: although Duns was not the inventor of formal distinction as
such, it was he who put it at the heart of his trinitarian theology. The concept of formal
difference is inextricably linked to the concept of formalities, which in this context
mean those ontological subunits in a concrete single essence between which there is
a formal difference. The basic impetus to the introduction of both concepts was the
necessity for rational expression of distinction between common divine nature and
those relations by which Persons are constituted (relations of fatherhood, sonship,
etc.), and also between different divine attributes. The task was, on the one hand, not
to destroy the absolute real unity in God, and, on the other hand, to explain certain
differences that exist in him before any act of intellect, even divine intellect. Therefore,
the notion of formality as a correlate “from the nature of the thing”, which corresponds to any attribute or relation, is conceivable in a separate concept.

dc.description.abstract

value:
The article discusses the issues of risk and risk-reflection in modern societies. It also illustrates
the role of the relationship of knowledge and power in the formation of ideas about risks and
the importance of risk reflection in maintaining order. A modern society is viewed as a world
formed on the basis of reflections and decisions. Risk reflections in risk management, understanding a situation and determining costs and benefits, are based on comprehensive knowledge
provided by experts, professionals, authorities and, finally, the authorities. The configuration for
exercising power is regulated by the configuration of knowledge or discourse, which controls the
direction of information and the language that support and disseminate ideas that orient actors’
actions. Discourse determines awareness and an understanding of the risks that actors may face.
The article notes that the problems are based on monopolization of the right to determine what
is considered a risk as well as what is its scope and possibilities of implementation. In this regard,
the discurse on risk for beneficiaries is the basis for public administration, as knowledge of risks
and their negative consequences becomes a motive for responsible behavior, in which individuals otherwise interpret, control, and direct their behavior. The article concludes that by considering risks in a controlled order, the authorities legitimize them. Risks are viewed as a representation of reality and this allows for the ability to manage the risk’s impact. The regulatory function
of power manifests itself indirectly, forming and transmitting knowledge and ideas. The purpose
of power is a modification of behavior when an individual, acting independently, contributes to
the achievement of the goals facing the power.

dc.description.abstract

value:
The article analyzes the theory of the origin of morality, presented by the Epicurean Hermarchus in his treatise “Against Empedocles” (Porph. De abstin. I, 7–12). The author expresses
doubt on the established point of view that Hermarchus, in criticizing Empedocles, actually
meant to criticize the philosophical schools of his day, and did not polemicize with the Pythagoreans and the followers of Empedocles, but with the Stoics, whom he did not name,
but had in mind. Exploring the Peripatetic and Epicurean tradition of using terms close to
the concept of oikeiōsis, which was introduced by Hermarchus to explain the prohibition of
killing a person by another person, the author of the article expresses the opinion that Stoic
Chrysippus, criticizing the teaching of the Epicureans about the aspiration for pleasure as a
person’s primary impulse in his essay “On the ultimate goal”, used this Epicurean term in his
theory of the origin of morality (Diog. Laert. VII, 85). Such an “interception” or reinterpretation of concepts was a fairly common device used by the Stoics in a polemic against Epicureanism. Hermarchus, unlike the Stoics, who understood oikeiōsis exclusively in the context of
the emergence of individual self-awareness and feelings of self-preservation, spoke about the
social meaning of oikeiōsis, which described people’s perception of each other within the human community and shows the impossibility of such an attitude towards living beings outside
this community (to animals). Later, the term oikeiōsis was considered to be Stoic, and its creation was attributed to Zeno.

dc.description.abstract

value: In the paper authors present a new approach to determination and computation of a solution for differential games with prescribed duration in the case when players lack certain information about the dynamical system and payoff function on the whole time interval on which the game is played. At each time instant players receive information about dynamical system and payoff functions, however the duration of the period of this information is unknown and can be represented as a random variable with known parameters. At certain periods of time the information is updated. A novel solution is described as a combination of imputation sets in the truncated subgames that are analyzed using Looking Forward Approach with random horizon. A resource extraction game serves as an illustration in order to compare a cooperative trajectory, imputations, and imputation distribution procedure in the game with Looking Forward Approach and in the original game with prescribed duration. Looking Forward Approach is used for constructing game theoretical models and defining solutions for conflict-controlled processes where information about the process updates dynamically.

value: Adjustable-Rate Bonds with Puts (ARBP), frequently issued by the Russian companies, give the issuer the right to arbitrarily change the coupon payments on the bonds at certain moments. But at these moments, the investor has the right to force the issuer to redeem the bonds at a face value. These reciprocal actions of the issuer and investors can be considered as a dynamic game. We suggest a game-theoretic model that allow to determine the optimal decisions of the players. These decisions are compared with empirical data.

For the lack of information about whether the dropper is present or not, two different states of nature can appear with some given probabilities at each stage. We study the non-cooperative behavior of players, and Nash equilibrium is considered as an equilibrium concept. We investigate how limited information about the dropper's appearance impacts the anti-jamming strategy.

dc.description.abstract

value:
Recent studies focused on the importance of adopting network analysis approaches such as social network analysis in the supply chain networks to better understand and manage the roles of organizations in inter-organizational relationships. The main aim of this research is to identify and integrate network analysis metrics in the existent literature in this realm which is applicable to characterize the position and role of organizations in the supply chain network context and their impact on the behavior and outcomes of organizations and the whole supply chain network.
To this aim, we followed a systematic literature review process using Scopus database to identify high-quality papers through several screening stages. Our findings illustrate that there are two main sources of interfirm differences including atomistic properties and relational properties. With an emphasis on relational properties through the lens of network analysis metrics, we integrated influential characteristics on actor’s behavior and performance into three main categories of node level, tie level, and network level.
Our findings are applicable to address any emergent phenomenon and the roles of actors based on their position in the network context such as supply chain network and study their behavior and performance.

dc.description.abstract

value: In this paper the problem of the supply chain expected profit maximization under the assumption of the short-term financing necessity for one of the supply chain parties using a coordinating contract is considered. The solution is derived for a two-echelon supply chain under the assumption of product demand being distributed as uniformly. A revenue-sharing contract with bank financing and a modified revenue-sharing contract with trade credit financing are explored. It is stated that none of the studied contracts is coordinating, as they do not provide the supplier’s expected profit maximum. The conditional coordination of supply chain with a modified revenue-sharing contract with trade credit financing is considered if the supply chain and the retailer’s expected profit maximum are reached and the supplier’s expected profit is greater than in case of application of a modified wholesale price contract with trade credit financing and a revenue-sharing contract with bank financing. It is proved that it is beneficial for both supply chain parties and the problem of the supply chain expected profit maximization under the assumption of the short-term financing necessity for one of the supply chain parties can be solved using a modified revenue-sharing contract with trade credit financing.

The article is devoted to the study of controlled grinding processes in a planetary mill.
The possibility of continuous monitoring of the fineness of grinding by using the laws of
automatic control, synthesized on the basis of the optimization approach, is considered. A
mathematical model of the control object in the linear stationary approximation is formed.
The dynamics of the obtained model is compared with data from field experiments according
to the main quality criteria of dynamic processes. For this model, a linear-quadratic controller
is synthesized, which is a combination of a Kalman filter that generates an optimal RMS
estimate of the object’s state vector with a linear-quadratic optimal state controller. The
article provides details of the implementation of the adopted approach and presents the
results of modeling dynamic processes for the considered closed-loop control system.

This article presents some new ideas connected to nonlinear and nonautonomous control

heart of the proposed methods. The discussion is focused on the optimal damping concept
first proposed by V. I. Zubov in the early 1960’s. Significant attention is paid to various
modern aspects of the optimal damping theory’s practical implementation. Emphasis is
given to the specific choice of the functional to be damped to provide the desirable stability
and performance features of a closed-loop system. The applicability and effectiveness of the
proposed approach are confirmed by an illustrative numerical example.

It is supposed that the structure of a target audience described by a weighted directed graph is already determined in the stage of network analysis, and marketing control actions are applied only to the members of strong subgroups (opinion leaders). Conditions of homeostasis (phase constraints) which reflect the requirements of sustainable management are introduced additionally. The Stackelberg equilibria are found analytically. It is shown that the interests of the principal and the firms are completely compatible.

dc.description.abstract

value: Motivated by research works on Zeuthen-Hicks bargaining, which leads to the Nash bargaining solution (Vetschera, 2018), we analyze data obtained during experimental resource allocation gaming with Yang-Hajek's mechanism from the class of proportional allocation mechanisms. Games were designed in the form of negotiation to allow players to reach consensus. Behavior models based on best response, constant behavior, and Nash bargaining solution are defined. Analysis conducted over decisions made by participants shows that a significant share of all decisions leads to an increase of Nash bargaining value. It is even higher than the share of decisions that are in agreement with the best-response concept. Consensus-ended games show more but subtle attraction to Nash bargaining solution behavior. We discuss how these decisions correspond with other types of behavior actively exhibited by participants of this experiments — so-called constant behavior and with the end of negotiation process in games.

dc.description.abstract

value:
The nature of popular science discourse in recent decades has acquired a convincing function, while it is addressed to an audience that is not always loyal to science. There are new
requirements for writing argumentative popular science texts and they must contain arguments that depend on the target audience. The need for a broad mastery of the skill of writing
well-reasoned popular science texts is associated with the issues of understanding how successfully their function has been implemented to convince the audience and thе explication
of technologies that help make these texts convincing, including the creation of a database of
typical basic arguments. It is believed that the methods of computer analysis used in computational rhetoric can be used to study the argumentative specifics of popular science literature,
and rhetorical argumentation should be the most productive approach to argumentation in a
popular science text because only it provides ways of interacting with the audience. However,
there are constraints for the development of this direction that make it difficult to find and
annotate arguments in a popular science text, namely: an ambiguity in understanding the
argument and argumentation, modeling various arguments depending on the understanding
of their structure and function, and finally, the target audience modeling. Explication of arguments in the text is possible through linguistic markers, but there is a problem of establishing
the boundaries of the argument. Identifying the internal structure of text segment relationships solves this problem, however, annotating the text is sensitive to certain methods of modeling argumentation. Based on the basic model of Toulmin’s argument, the special aspects of
modeling rhetorical argumentation and its dependence on the target audience are illustrated.
It is proposed that the concept of a universal audience can hardly be adapted to practical tasks,
and criteria that are consistent with the format of truths and the format of audience values, the
implementation of which could bring the target audience closer to an universal one. The author demonstrates the features in the pragma-dialectical approach, which, despite its popularity in computational rhetoric, do not allow it to be fully adapted to popular science discourse.

dc.description.abstract

value:
The article examines some aspects of the theoretical legacy of Abū ‘l-Ḥasan al-Māwardī, a medieval Islamic theologian and jurist. This prominent scholar, who lived a long and eventful life,
wrote a number of works that left a noticeable mark in the political and legal thought of Islam.
Al-Māwardī also wrote several significant treatises in Islamic theology and Jurisprudence.
Among them are works devoted to commenting on the Qur’ān — Nukat wa’l-‘uyūn [Tafsīr
al-Māwardī], ’Amthāl al-Qur’ān, as well as a treatise on Prophethood — ’A‘lām al-Nubuwwa.
Another important but still insufficiently studied treatise of al-Māwardī on Jurisprudence
is called Kitāb al-Ḥāwī al-kabīr fī fiqh madhhab al-Imām al-Shāfi‘ī. It is generally accepted
that al-Māwardī‘s essay called al-’Iqnā‘ made him famous in his lifetime. This legal guide to
the Shafi‘i law certainly strengthened the professional authority of al-Māwardī as the leading
Shafi‘i faqih and apparently contributed to the growth of his political influence in medieval
Baghdad. Despite the merits and recognition of al-Māwardī as an authoritative connoisseur
of Islam, his creative search was not limited to writing works on religious topics. Al-Māwardī
‘s obvious interest in scientific disciplines was, in particular, confirmed in several studies on
philology. He wrote at least two works on this subject: namely, ’Amthāl wa’l-ḥikam and Kitāb fī
al-naḥw. However, the scholars who study the heritage of al-Māwardī deal mainly with his socio-political works. Al-Māwardī was known as a gifted and experienced diplomat who repeatedly acted as a mediator in solving complex political problems. As an adviser for many years at
the Abbasid court, al-Māwardī composed several works on the theory of state and governance,
such as al-Aḥkām al-Sulṭāniyya, Qawānīn al-wuzarāʾ wa- siyāsat al-mulūk, as well as Tashīl
al-naẓar wa-ta‘jīl al-ẓafar fī ’akhlāq al-malik wa-siyāsat al-mulk etc. These works, diverse not
only in content, but also in genre, mainly reflect the essence of political processes of that time.

dc.description.abstract

value:
Distinguishing myths in terms of their veracity had almost been neglected in Plato’s studies. In
this article, the author focuses on Plato’s controversial claims about the truth-status of myths. An
attempt is made to elucidate what he really had in mind when assessing the veracity of myths.
The author claims that Plato, while discussing the epistemic status of myths,  actually distinguished three kinds of myths in regard to what they narrate. Additionally, it is argued that he
endorses three different kinds of truth value for myths: they can be either true or false, probable,
or factually false but conveying some valuable truths. In the Republic II and III, Plato implicitly
distinguishes the truth value of theological myths from the truth value of aetiological and normative ones, each of which are explained in detail in the article. In Plato’s view, the theological
myths can be either true or false, because he determines the divine nature a priori. When ascribing the probable character to myths, Plato has in mind mostly aetiological myths. Given that we
are unable to establish the truths on the origins and development of many phenomena, because
they originated in the remote past, what we can do is to reconstruct plausible and consistent
myths of these phenomena, which, among others, might contain the arguments and even proofs,
such as the proof of the cosmic destruction in Plato’s own myth in the Politicus. In the third case,
when Plato says that myths are lies, yet containing some truth, he had in mind myths which
might be the product of our imagination like eschatological myths, for example. Being a kind of
fiction, they are false, in the sense they do not correspond to any real state of affairs. Since they
convey profound ethical norms or religious insights, they can be regarded as true.

dc.description.abstract

value:
The complete translation of cultural heritage into a digital format acutely poses the question of
art’s place in the digital era. The search for an answer is built upon the foundation of proposed
evolutionary models of the genesis of art. Transitional periods from one historical cultural era to the next are characterized by a change in the most popular types of art. The establishment
of one or another type of art is rigidly connected with the introduction of new data storage
media and coding techniques. The constant increase in the variety of genres and media has
culminated in the digital display. The appearance of a universal digital media must be reflected
in the energetic reconstruction of the artistic world, but the birth of new types of art will lag
behind. Moreover, the problem of the existence or non-existence of art also becomes relevant.
In parallel with the elimination of literature, a virtual excarnation of object plasticity is occurring. It is possible that art is irreversibly forsaking sensual and bodily language, but the idea
that it is using such an unexpected lexicon in an attempt to break through to the individual
directly seems more productive. The purpose of art is to expand the space of consciousness.
The digital age is distinguished by its possibility to transform this space in surprising ways.
Digitalization of a work has a clear basic similarity to the physiological process of convolution
of a sensory signal in the depths of the brain. Computer-based dipoles and neural synapses are
binary structures, described in binary symbols. A work that has been translated into digits can
be seen as the projection of a certain neural configuration that has come together in the depths
of consciousness and is revealed in the form of an image. The likely prospects of obtaining,
instead of projections, a multi-dimensional digital display, as well as the potential possibility
for the psyche to adequately decipher it, portend a holistic reading of the work and even closer
contact between the artist and the addressee. Right on the horizon is the path towards a synthesis of images that go beyond the limits of the usual forms and sensations. And nowadays
unimaginable classes of feelings are capable of generating many vibrant “types and genres”. At
the same time, threatening to the habitual methods of sensory perception and facilitating the
liberation of the spirit, the excarnation of art works promise a categorically new stage in the
genesis of art as well as a different level of creation and perception.

dc.description.abstract

value:
The article examines Danilevsky’s approach to the analysis of the role of influences on the
formation and changes of cultural-historical types. Several contradictions in Danilevsky’s
consideration of the phenomenon of influences are underlined. They were caused by an insufficiently clarified analysis of the correlation between the universal and the concrete historical, and by some monotheistic and typological aspects in the analysis of historical development.
Danilevsky clearly underestimates the significance of the interaction between successive and
synchronously developing cultures, which leads to a diminution of world-historical trends in
the development of mankind. The article stresses a polemical character of a number of provisions of Danilevsky’s concepts. The urgent significance of the philosopher’s conclusions about
the need to protect national cultural values is emphasized, which is especially important in
the context of modern globalization processes. Additionally, some key risks of philosophical
tendencies of Russian thought are pointed out in regard to the dream of world hegemony, or
towards autocratic otherness. These dangers arise largely from the lack of practical and theoretical differences in the use of unprocessed European concepts, and therefore Russian history
can often be viewed as a sequence of attraction to and repulsion from the West. The article
also stresses that the “Russian idea” (which can be seen, in Solovyov’s understanding, from
a religious standpoint as the one brought by the Russian people to the Last Judgment of the
World as a unique contribution to universal human consciousness) is not a “dream” of world
hegemony or the autocratic “otherness”, according to which all good is always “one’s own”, and
all evil is “somebody else’s”, but it is some antinomic perception of universal salvation, which
was also noted by Dostoevsky, Florensky, Bulgakov, and others.

dc.description.abstract

value:
The article, as a result of the analysis of the philosophical and methodological content of the
new knowledge and dynamics of science concepts, substantiates the thesis about the necessity to radically shift the research priorities of the modern philosophy of science. The author
critically evaluates the current methodological potential of the philosophy of science, which
has developed on the basis of postpositivist concepts of scientific knowledge, and he attempts
to outline the philosophical-methodological problems associated with modern scientific
trends. According to the author, attention on the philosophy of science should be focused
today, first of all, on interdisciplinary research programs that are implemented in the most
popular and advanced areas of scientific knowledge. Within these programs, it is not the theoretical constructions (and their relationships), but the disciplinary structures of knowledge
that act as the main cognitive unit of the organization of knowledge. Thus, to the fore of the
philosophical-methodological approaches come the tasks related to the search and the analysis of methodological guidelines that provide cognitively effective communication (mutual
understanding) of scientists within collaborations, i. e. interdisciplinary scientific teams. The
author believes that the epistemological perspectives of comprehension and methodological
development of such guidelines open up when referring to the cultural-historical dimensions
of scientific knowledge. It is the cultural-historical epistemology that takes into account the
existential, motivational attitudes of the scientist, which at the same time assume methodologically significant parameters of scientific research (the style of scientific thinking, the dignity
of knowledge, and the historical continuity of science as a cultural phenomenon). As a result,
the cultural-historical epistemology opens up the possibility of an effective methodological
orientation of the most important areas in modern science.

The article considers a controlled system of linear differential-difference equations with a

For a linear differential-difference equation of delayed type with linearly increasing delay, the
canonical Zubov transformation is applied and conditions for the stabilization of such systems
by static control are derived. An algorithm for checking the conditions for the existence of a
stabilizing control and for its constructing is formulated. New theorems on stability analysis
of systems of linear differential-difference equations with linearly increasing delay are proven.
The results obtained can be applied to the case of systems with several proportional delays.

dc.description.abstract

value: The income tax system is the main instrument of fiscal policy that aims to improve income distribution and economic growth, but the problem arises when there is corrupt behavior in that system. While the tax audit is a tax control tool that is costly, the tax system should guarantee, however, the instruments for tax collection. In this research work, we formulate a model in which all taxpayers decide to pay taxes or not according to their personal income, individual preferences with respect to the audit and tax control information perceived in their social environment. We develop a theoretical model to study the structure of citizen networks that must pay taxes. First, we assume that citizens are classified by two social groups, the rich and the poor. When all citizens are taxpayers, but public authorities are corrupt, we show that the poor group is the most affected by corruption. However, when taxpayers are corrupt or tax evaders, we implement mechanisms to audit and control this corrupt behavior. Hence, we show that this situation of corruption and control of tax payments can be represented by several well-known theoretical games. Then, we apply the evolutionary theory of the game in the network considering that each taxpayer receives information from his∖her neighbors about the probability of audit and that he∖she could react according to his∖her risk status and real income. Such behavior forms a group of informed agents that propagate the information beyond the proportions of the informed and uninformed contributors that are modified. Our evolutionary model in the structure of the network describes the changes in the population of taxpayers driven by the impact of information on the future fiscal audit. Our simulation analysis shows that the initial and final preferences of taxpayers depend on important parameters, that is, taxes and fines, audit information and costs.

dc.description.abstract

value: We consider a dynamic Stackelberg game theoretic model of the coordination of social and private interests (SPICE-model) of resource allocation in marketing networks. The dynamics of controlled system describes an interaction of the members of a target audience (basic agents) that leads to a change of their opinions (cost of buying the goods and services of firms competing on a market). An interaction of the firms (influence agents) is formalized as their differential game in strategic form. The payoff functional of each firm includes two terms: the summary opinion of the basic agents with consideration of their marketing costs (a common interest of all firms), and the income from investments in a private activity. The latter income is described by a linear function. The firms exert their influence not to all basic agents but only to the members of strong subgroups of the influence digraph (opinion leaders). The opinion leaders determine the stable final opinions of all members of the target audience. A coordinating principal determines the firms' marketing budgets and maximizes the summary opinion of the basic agents with consideration of the allocated resources. The Nash equilibrium in the game of influence agents and the Stackelberg equilibrium in a general hierarchical game of the principal with them are found. It is proved that the value of opinion of a basic agent is the same for all influence agents and the principal. It is also proved that the influence agents assign less resources for the marketing efforts than the principal would like.

The influence of the agents on each other is taken into account in the equation of dynamics of agents' opinions. An agent weights the other agents' opinions and after that forms the next step opinion. Two types of communication structures are considered in the model. The results of numerical modeling illustrate the influence of some parameters of the model (control, influence power of agents on each other) on the optimal opinion dynamics.

It is noted that the Kelvin—Voigt model is unsuitable for describing some polymers and
biological tissues. In these cases, a three-component combination of elements, which consists
of a spring and damper, connected in parallel and a spring sequentially attached to them,
is used. The force characteristic of such a combination includes not only the strain, strain
rate, and force, but also the rate of force change. Examples of such systems are the blood
vessel wall and the intervertebral disc, which have been given special attention. Since the
motion of such systems is described by an ordinary third-order differential equation, they
are classified as systems with a non-integer number of degrees of freedom. For a single-mass
oscillating system with one and a half degrees of freedom, a transfer function was constructed
using the Laplace transform. In addition, the amplitude-frequency response (AFR) was also
constructed. Analysis of this characteristic showed that increasing the damping coefficient
from zero to infinity first leads to a decrease in its maximum to a certain non-zero value, and
then to an increase and reaching infinity with an infinite value of the damping coefficient.
The same feature is demonstrated on a two-mass system of chain structure, each link of
which has one and a half degrees of freedom. A sequential combination of seven such links
was used to model the lumbar spine in the structure of a General body model of a sitting
person subject to vertical vibration. Multi-link elastic-viscous joints were used to model the
multi-articular muscles of the lumbar spine. Additional experimental studies are needed to
determine the numerical values of the parameters of the proposed model.

title: Optimal pricing structure in a maintenance contract: a game theory approach

value: Cristino, Claudio T.

dc.description.abstract

value: This essay presents a novel look at Murthy and Asgharizadeh's study (Murthy & Asgharizadeh, 1998). The authors developed a decision problem applied to maintenance outsourcing involving two decision-makers (players). If a consumer buys a product, then outsources the maintenance actions to a maintenance agent (agent) who offers two maintenance options; a maintenance contract that holds a penalty clause which is activated if the agent's time to repair is higher than a specified time, and services on-demand. The model yields equilibrium strategies based on the subgame-perfect Nash equilibrium. The agent defines the optimal pricing structure for the maintenance options considering the equipment's useful life while the consumer maximizes their expected payoff by choosing one maintenance option. Our contribution to this research branches in three ways. First, once the model deals with random variables, it represents a stochastic optimization problem. We propose a different approach to estimate this penalty time by using the Monte Carlo method. The second contribution is to present a formal definition of this decision problem as a game, emphasizing the game theory's components. Finally, we reinterpret the players' equilibrium strategies.

dc.description.abstract

value: We consider a differential simple search game without phase constraints on the plane. Each pursuer from the team chooses an initial position and piecewise constant strategy. As an example, the game of simple search of immobile hider (evader) on the plane is considered, and the necessary conditions for detection are found. For cases with two and three pursuers, a comparison of the detection time of the evader was made and approximate information sets numerically constructed.

dc.description.abstract

value:
The article is devoted to the study of the problem of autocephaly of Orthodox Churches in Russia during the nineteenth and twentieth centuries. Interest in this aspect of aspect of Orthodox ecclesiology and canon law intensified not only because of the development of Orthodox
theology in Russia, but also due to the fact that this problem acquired political significance. It
was connected with some matters of domestic and foreign policy of the Russian Empire. The
annexation of Georgian in the early nineteenth century and liquidation of the autocephaly of
the Georgian Church by the decision of the secular authorities provided the enduring source
of the anti-governmental mood among Georgian elite, traditionally closely connected with the
local clergy. The foreign policy interests of the empire in the Near East and Asia Minor also
contributed to the intensification of research in the field of ecclesiastic history and the modern
structure of ancient patriarchates. The greatest factor that contributed to an increase in such
research interests was the emergence of new autocephalous churches: the Greek and Bulgarian churches separated from the Patriarchate of Constantinople. Separation of the Bulgarian
Church provoked an aggressive polemic in the Russian press. The problem of nationalism was
highlighted, which is significant for the Orthodox tradition. As an attachment to the article,
the authors include the text of a report on the possibility of the autocephaly of the Georgian
Church composed by Vladimir Beneshevich in 1917. The report was made upon request of the
Provisional Government and it is preserved in the collection of Beneshevich at the St. Petersburg Branch of the Archive of the Russian Academy of Sciences.

The classical problem of stationary stabilization with respect to the state of a linear stationary control system is investigated. Efficient, easily algorithmic methods for constructing
controllers of controlled systems are considered: the method of V. I. Zubov and the method of
P. Brunovsky. The most successful modifications are indicated to facilitate the construction
of a linear controller. A new modification of the construction of a linear regulator is proposed
using the transformation of the matrix of the original system into a block-diagonal form. This
modification contains all the advantages of both V. I. Zubov’s method and P. Brunovsky’s
method, and allows one to reduce the problem with multidimensional control to the problem
of stabilizing a set of independent subsystems with scalar control for each subsystem.

dc.description.abstract

value:
The intellectual heritage of thinkers of the Russian abroad today is increasingly attracting the
attention of researchers of Russian philosophy of the first half of the 20th century. Although
the author clarifies, one can sometimes hear that we are talking about philosophers of a kind
of “second place”, since thinkers of the level of Berdyaev, Shestov, and Stepun are already quite
fully and comprehensively represented in the relevant literature. The author of the article believes that it is not enough to limit oneself to only historical-philosophical academic interest in
turning to the work of philosophers of this era. With great attention and breadth, sometimes
anew, to the ideas of thinkers of the Russian abroad, we are forced to turn to the changing
socio-spiritual situation of our time. The processes of globalization, the contacts of cultures,
and civilizations make their heritage extremely relevant today. A striking example of this is the
work of Pyotr Bitsilli. Based on several of Bitsilli’s works, and in particular on his article Nation
and Language, the author emphasizes the specific relevance of the methodological strategy of
the philosopher and historian. In addition, the author reveals another specific aspect of Bitsilli’s methodology — the interdisciplinary nature of his research. It is the breadth of intellectual horizons, as well as in-depth knowledge in the field of philosophy, history, and linguistics,
that distinguish Bitsilli. His work is gaining particular semantic fullness at present, when the
themes of the nation, language, culture, as well as their correlation, are given new perspectives
in modern socio-cultural dynamics. The author of the article suggests that hermeneutic and
narrative approaches allow them to acquire specific features in the philosophical interpretations of Bitsilli.

The article presents data on the status of dependent and value orientations of people on their
attitude towards social groups that differ from the majority of the population. Based on the
analysis of the data of the 6th wave (2010–2014) of the World Values Survey, which shows
that social levels occupying intermediate positions in the system of social statuses and value
orientations are more tolerant than the layers occupying the extreme positions as representatives of social minorities. Intergroup relations are influenced by many factors, and intergroup
relations themselves are often controversial. Therefore, in one situation, they can smooth out
the prejudices that exist between groups, and in others, on the contrary — incite. The article
focuses on identifying groups that have a high degree of tolerance. The study uses various
indicators of intergroup tension. The results of a comparative cross-country analysis of an
integrated database (1981–2014) of the World Values Survey are presented. It was found that
an increase in the proportion of the lower middle class and people with a mixed post-materialistic orientation in the course of secondary modernization helps ensure a low incidence
of negative intergroup attitudes. When interpreting the obtained results, the article uses the
theory and method of measuring values developed by Ronald Inglehart, as well as the typology of countries proposed by Nikolai Lapin. All calculations were performed using IBM SPSS
Statistics 25.0, Statistica 6.0, and statistical analysis methods, for example cluster analysis.

dc.description.abstract

value:
The purpose of the article is to trace the development of the idea of subjectivity in bioethics, starting from the level assumed by the prevailing model of personal autonomy up
to the cosmopolitan dimension innate to the global model proposed by Van Rensselaer
Potter. In the article, autonomy is considered in the more general context of the individualization of Western societies. It is revealed that autonomy is inherently dependent on the
idea of human well-being and the values of individualism and therefore it can be reduced
to individual decisions. This devaluation of personal autonomy finds justifiable criticism
among bioethicists. The concept of the subject is restored in the frame of the substantive
model of autonomy indicating the inextricable connection of a choice and a common personal perspective. Such an individualistic approach to the subject is initially limited. Being
concentrated on the behavior of a rational individual, the approach localizes all relevant
ethical cases. In the modern world, global problem intersect with each other they cease to
be noticed and moreover become intimatized due to their individualistic description. This
approach to the subject is thus inadequate and needs to be replaced. For this purpose, the
difference between the two traditions within bioethics must be overcome: an autonomous
person and cosmopolitan remain the two significant models of subjectivity, and the bridge
between them has never been built. The article explores the possibility of such a transition
to a cosmopolitan position on the classic example from The Phenomenology of Spirit. It
can be concluded that the current position of the theory of the subject is tenuous on both
flanks of bioethics. When it loses the message of subjectivity and becomes a servant of the
technological approach, we get just another version of medical ethics and lose the long-term
perspective appropriate for the cosmopolitan world.

value: Li, Yin

dc.description.abstract

value: The problem of constructing the Dynamic Nash Bargaining Solution in a 2-stage game is studied. In each stage, a minimum cost spanning tree game is played, all players select strategy profiles to construct graphs in the stage game. At the second stage, players may change the graph using strategy profiles with transition probabilities, which decided by players in the first stage. The players' cooperative behavior is considered. As solution the Dynamic Nash Bargaining Solution is proposed. A theorem is proved to allow the Dynamic Nash Bargaining Solution to be time-consistent.

title: Mechanism for shifting Nash equilibrium trajectories to cooperative Pareto solutions in dynamic bimatrix games

dc.contributor.author

value: Krasovskii, Nikolay A.

value: Tarasyev, Alexander M.

dc.description.abstract

value: In the paper, constructions of the generalized method of characteristics are applied for calculating the generalized minimax (viscosity) solutions of Hamilton-Jacobi equations in dynamic bimatrix games. The structure of the game presumes interactions of two players in the framework of the evolutionary game model. Stochastic contacts between players occur according to the dynamic process, which can be interpreted as a system of Kolmogorov's differential equations with controls instead of probability parameters. It is assumed that control parameters are not fixed and can be constructed by the feedback principle. Two types of payoff functions are considered: short-term payoffs are determined in the current moments of time, and long-term payoffs are determined as limit functionals on the infinite time horizon. The notion of dynamic Nash equilibrium in the class of controlled feedbacks is considered for the long-term payoffs. In the framework of constructions of dynamic equilibrium, the solutions are designed on the basis of maximization of guaranteed payoffs. Such guaranteeing strategies are built in the framework of the theory of minimax (viscosity) solutions of Hamilton-Jacobi equations. The analytical formulas are obtained for the value functions in the cases of different orientations for the “zigzags” (broken lines) of acceptable situations in the static game. The equilibrium trajectories generated by the minimax solutions shift the system in the direction of cooperative Pareto points. The proposed approach provides new qualitative properties of the equilibrium trajectories in the dynamic bimatrix games which guarantee better results of payoffs for both players than static Nash equilibria. As an example, interactions of two firms on the market of innovative electronic devices are examined within the proposed approach for treating dynamic bimatrix games.

title: Supply chain finance solutions in joint working capital management

dc.contributor.author

value: Kuzmina, Yana I.

value: The research is devoted to joint working capital management in supply chains aiming to improve joint working capital management methods through minimization of financial supply chain costs on working capital using Supply Chain Finance (SCF) Solutions. Though SCF applicability in Financial Supply Chain management has recently been studied to relieve access to capital sources, managerial perspective of SCF solutions is still uninvestigated as well as few other areas. The research suggests a managerial algorithm that contains four developed models: the model of Collaborative cash conversion cycle two models of SCF solutions and the model of Joint Working Capital optimization. The models imply using such SCF solutions as Factoring, Reverse Factoring and Inventory Financing to improve Joint Working Capital in terms of costs on it and liquidity of both supply chain members and entire chain, providing the optimal conditions of SCF solutions. Quantitative optimization with SCF solutions demonstrates on the cases of supply chains the improvement of financial position and liquidity of all chain members. The research has a potential to de applied in businesses since the algorithm represents a comprehensive managerial tool for Joint Working capital management in supply chains. It might be used to achieve optimal cash conversion cycle values for minimal supply chain costs on working capital constrained by liquidity and profitability target levels.

value:
Based on the asymptotic expansions obtained by the multi-scale method up to the third order
of smallness for the potential velocity of liquid particles and the plate-fluid surface elevation,
the dispersion properties of the vibrations generated by the interaction of progressive surface
wave harmonics of finite amplitude are analyzed in the article. The effect of nonlinearity of
acceleration of vertical displacements of an elastic plate on the dispersion characteristics of
wave disturbances is studied. The dependence of the vibration frequency is estimated by
taking into account the nonlinearity of the first and second approximations values, the plate
thickness, and the longitudinal compressive force. It is shown that the sign of the amplitude
of the second interacting harmonic and the nonlinearity of the acceleration of vertical
displacements of the longitudinally compressed elastic plate affect the vibration phase. It
was found that with a decrease in the wavelength of the initial harmonic, the influence of the
plate’s nonlinearity vertical acceleration is enhanced. The presence of compressive force is
manifested in a decrease in the frequency of vibrations of the wave disturbance in comparison
with the frequency obtained in the absence of longitudinal compression, both with a positive
and negative sign of the second interacting harmonic amplitude.
