Overcoming “The Language Rubicon": Versions, Steps and Evolutionary Mechanisms
Authors:   Institute of Philosophy and Law of the Siberian Branch of the Russian Academy of Sciences, Novosibirsk, Rozov Nikolai ,   Novosibirsk State University, Russian Federation,   Novosibirsk State Technical University, Russian Federation
Published: January 2022

The most plausible hypotheses explaining the breakthrough of our distant ancestors to articulate speech and consciousness include: rituals of solidarity (singing, grooming, facial expressions, gestures), the role of "labor", teaching children, changes in gender relations, recruiting (mobilization for collective action), laryngeal transformation, brain growth, mirror neurons, neuronal overlap; dominance of coalitions over loners, self-domestication, the need to coordinate decisions; joint intentionality, development of normativity. The concretization of the principle of "cultural drive" leads to the following concept: new environmental, social and communicative challenges and concerns lead to multiple trials; successful behavior is consolidated in group practices, mental structures of participants, and hereditary inclinations with multilevel selection and change of many generations. Overcoming the "language Rubicon" took place in several steps, or stages, in which the structures that have developed to provide concerns lead to new concerns that require new structures. Such concerns as pacifying social order in the group, signaling general discontent, coordinating actions, etc., the following structures emerged: egalitarian coalitions with collective practices of intimidation, sound signals uttered in unison, training and self-training, self-domestication, shared intentionality, and normative rituals. The most plausible versions supplement this concept. Сhoral singing as a ritual of solidarity promoted the ability to imitate and articulate. Mirror neurons and neural overlaps have played the role of providing mechanisms for imitation and association processes. The connection between "labor" and speech was complex and interdependent, mediated by normativity. Recruiting as signals of mobilization for collective action also made its contribution but only under the already established normative order. Social learning is in fact a special ritual of constant trial and adjustment which has grown out of a normative ritual. The establishment of a new order of sexual relations also played a role: under the prohibition of violence and rape it was necessary to involve partners. Speech replaced grooming, and those who spoke clearly, convincingly and/or sang beautifully received benefits in sexual selection. The totality of all these processes reinforced the concerns of mutual understanding which were provided by the rituals of naming with the following multiplication of protowords and further growth of linguistic complexity.
On Art Contents of Maqam
Authors:   Novosibirsk State Glinka Conservatoire, Russian Federation, Karpychev Mikhail
Published: January 2022

The article is devoted to researching Islamic professional oral music. Maqam is the most high form of this, its conception is spiritual catharsis. Maqam is a chain of ascending parts, each of them elaborating on the main theme of the music. It progresses to a culmination and then descends to the cuitial stage. Maqam’s spiritual contents are the sorrow of love in the form of improvisation first of all, but also songs and dances. Maqam unites dramatic and lyrical characters. Every maqam has its own semantic canon, which is actualized by means of the deepest research of human feelings. Semantic and structure canons connect with the performer’s liberty in emotional detail. Maqam represents a peculiar type of authority (not in absolute form of composer’s art) and is based on classical orient poetry. The highest form of maqam is instrumental (without singing), which expresses the character of its singing-instrumental “parent”. The maqam’s performers must have a special complement of musical abilities and study in music empirient schools. It is necessary to mark particular antithesises, which illustrate a “emotion–ratio” relation in macam’s dramaturgy: passionate contents and strict verified form; originality and canon; euphoria and self-control of a performer; melody and polyphony (instruments imitate singing). Maqam represents a penetrating, “endless” melody with its ability to develop. The elite character of maqam’s genesis and contemporary democracy of the genre are explored, as well as the relations between two forms of maqam: maqam-tune and maqam-genre.
Socio-Cultural Basis of the Consumption Act as a Purpose of Emotional Experiences During Everyday Practices of Interaction With the Urban Space
Authors:   Saint-Petersburg State University of Industrial Technologies and Design, Russian Federation, Parshukova Polina
Published: January 2022

The COVID-19 pandemic refreshes the view of urban spaces as objects of consumption. The article describes the constituent elements of urban space and the process of human interaction with it, mediated by sign-symbolic perception. The socio-philosophical analysis of the phenomenon of consumption as a phenomenon developing within the framework of understanding the praxeological relationship of human to world is presented. The study contains a synthesis of several modern concepts based on a sociocultural approach. Based on the concept of A. Warde, the author proposes that consumption be seen as a process that is a moment in the many practices of everyday life which is characterized by evaluation, use and appropriation. The act of consumption is viewed as an internally-oriented, goal-rational human behavior aimed at achieving emotional experiences, as a part of the self-determination of the individual (G. Schulze). The conceptual link explaining the articulation between emotion and consumption is to be found in the notion of “imagination”, understood, following E. Illouz, as the socially situated deployment of cultural fantasies. In everyday practices of the development of urban spaces by man, a combination of creation and use is found, which seems to be possible to conceptualize through the moment of appropriation, in the course of the act of consumption, considered as secondary production (M. de Certeau). Changes in everyday practices and human attitudes towards urban spaces during the COVID-19 pandemic are analyzed based on domestic and foreign research. The possibility of consolidating new forms of everyday practices is comprehended. Strengthening of a person's intrasubjective orientation is stated.
The After Life of the Buddha: Parinirvana Images in Eurasia
Authors:   MMAJ Academy of International Studies, New Delhi, India, Doraiswamy Rashmi
Published: January 2022

This article examines religions in which the life of the spiritual leader is as important as the death, and where the narratives of death (and not just of life) enter the image cycles in art. The Buddha willed himself to die when he was eighty at Kushinagara. Buddhism is one of the rare world religions where there is a huge repertoire of mahaparinairvana images. Buddhism values the release from the cycle of rebirths and deaths. The sets and cycles of images that make up the representation of the death of the Buddha in sculpture and paintings in caves spread across Eurasia are described in detail. The death images are important spatially, materially and culturally. These images began to be made in Mathura, were perfected at Gandhara and travelled all the way across Central Asia to China and beyond. The relics left behind after cremation were enshrined in stupas. They represented a continuation of dharma, of the presence of the Buddha even after he had passed on. The article analyses in detail three caves – Cave 26 in Ajanta in Maharashtra, India; Cave 205 in Kizil in Kucha, Central Asia (East Turkestan) and Cave 148 in Mogao, Dunhuang, China. All three caves juxtapose monumental images of the Dying Buddha with different themes related to his death: The Temptation of Demon Mara in Cave 26, Ajanta; how King Ajatashatru was told of Buddha’s passing along with the cremation of the coffin with the mahaparinirvana Buddha in it in Cave 205, Kizil. Cave 148 at Mogao contains the most complete set of scenes and images representing events pre- and post- Buddha’s death in sculptures and murals. In addition, there are Chinese interpretations of the Pure Lands in large murals.
Substantiation of the Testimonial Knowledge in the Religious Epistemology: The Approach of J. Greco
Authors:   Lomonosov Moscow State University, Russian Federation, Khmelevskaya Svetlana , Yablokova Natalia ,   Moscow State Technological University STANKIN, Russian Federation
Published: January 2022

Currently, the study of religious knowledge is carried out mainly within the framework of religious epistemology, which does not exclude its consideration from the standpoint of a non-cognitive approach, for example, fideism. However, the greatest interest is in cognitivism, whose proponents explore the problems of religious knowledge using a number of standards of classical epistemology, yet at the same time modify them, creating standards of religious epistemology proper. One of the authors who develop this direction is J. Greco, who continues the tradition of studying evidence ("testimonial evidence") and its role in the formation and functioning of religious consciousness. In an effort to organize witness knowledge, he tries to typologize it, distinguishing, on the one hand, knowledge presented as a set of witness data, and, on the other hand, as knowledge transmitted and assimilated in the processes of communication that take place, for example, within a religious community. J. Greco criticizes the arguments of skeptics who claim that it is impossible that the evidence can serve as a sufficient basis for religious belief. The article emphasizes the simplicity of such an approach, since J. Greco does not distinguish the types of knowledge that are formed as a result of evidence (in particular, reflexive and value-based knowledge, which are formed and assimilated in different ways), which are different in their epistemological characteristics. At the same time, he focuses on a problem that is significant not only for religious, but also for classical epistemology, namely, the influence of the moral authority of a particular form of comprehension of being (science, religion, etc.) and its specific representatives who develop the relevant knowledge on the assimilation of certain epistemic truths by both specialized communities (for example, the scientific community) and society as a whole. The philosophical arguments of J. Greco shows that the theme of religious evidence within the framework of classical epistemology is not reduced to banal statements that they do not meet the criteria generated by scientific knowledge. These reflections touch upon a number of topics relevant to this epistemology. At the same time, these arguments point to the need to develop a religious epistemology based on the specifics of religious knowledge with its own verification criteria and methodology for obtaining it.
ЦИФРОВАЯ МОЛОДЕЖЬ И РОЛЬ ЭКОЛОГИЧЕСКОГО ТУРИЗМА В ПРЕОДОЛЕНИИ РИСКОВ ЕЕ СОЦИАЛИЗАЦИИ
Authors: Саидова Липа Исаевна
Published: January 2022

Аннотация. Целью исследования является постановка проблемы рисков социализации молодежи в условиях цифровой среды и возможностей их преодоления с помощью экологического туризма. Социальная актуальность данной темы определяется уходом молодежи в цифровой, виртуальный мир, отчуждением от естественной природной среды и снижением социального здоровья.

Методологическую базу исследования составляют подходы и концепции, точки зрения и идеи, сформировавшиеся в современном научном дискурсе относительно таких понятий и явлений, как «цифровое общество», «цифровая среда», «цифровая молодежь», «цифровое поколение», а также положения функционального подхода, позволяющие раскрыть социальные функции экологического туризма как подсистемы/вида туризма, оказывающего социализационное влияние на молодое поколение цифровой эпохи.

Результаты исследования позволили обосновать точку зрения о противоречивом характере цифровой социализации современной молодежи, для которой цифровая среда является, с одной стороны, естественной, гармоничной и необходимой для жизненной самореализации, а, с другой — рискогенной, так как она способствует отчуждению молодых поколений и от социального окружения, и от окружающей природы, которая все больше утрачивает в восприятии цифровой молодежи характер естественной среды обитания человека.

В данных обстоятельствах экологический туризм привлекает внимание как мощный ресурс социализационного воздействия на молодежь. Этот вид туризма позволит не противостоять цифровым (виртуальным, сетевым) практикам коммуникации, формирования связей и отношений, а формировать сбалансированный характер социальных практик, производных от разных миров — виртуального, цифрового (искусственного) и реального, природного (естественного). Такой механизм позволит блокировать ряд рисков социализации в цифровой среде, связанных со страхами оказаться вне Сети, вне цифрового пространства и без средств цифровой коммуникации; раскроет перед молодежью другой мир с необходимостью его защиты, сохранения от негативного воздействия человеческой деятельности, в том числе и туристической.

Перспективу исследования составляет дальнейшее научное изучение данной проблематики, которая может быть представлена в более широком тематическом и концептуальном контексте, связанном с оперированием понятием «экологизация». Речь может идти об экологизации туристских практик молодежи и других возрастных групп, об экологизации сознания и поведения молодежи, о формировании ее экологической культуры. В любом случае, реализация этой задачи, связанной с экологизацией цифровой молодежи, предполагает обращение к потенциалу экологического туризма, к разработке методологического и эмпирического инструментария для проведения глубоких социологических исследований и разработке на их основе рекомендаций соответствующим структурам, организациям, институтам.

EXPLORING STUDENTS’ STEM IMAGINATION PROCESS THROUGH AN ENGINEERING DESIGN PROCESS
Authors: Siew Nyet Moi
Published: January 2022

This research was conducted to explore the STEM imagination of Grade 10 students from one Malaysian rural secondary school that adopted the integration of the imagination process in an Engineering Design Process (EDP) through an outreach program in STEM. Four stages of the STEM imagination process were examined: initiation, dynamic adjustment, virtual implementation and implementation. A total of 50 students aged 16 participated in a 10-hour program which engaged them in designing and building two different prototypes. Data on students’ STEM imagination were captured through teachers’ field notes based on focus group interviews and observations. The findings reveal that students needed to draw from their lived experiences to brainstorm problems and solutions around a given scenario, and to arrive at a workable solution in order to move from the initiation to the implementation stage. The findings also suggested that the EDP approach is able to create a supportive environment for nurturing STEM imagination among rural secondary school students.
On Some Decompositions of Matrices over Algebraically Closed and Finite Fields
Authors:   Institute of Mathematics and Informatics, Bulgarian Academy of Sciences, Danchev Peter
Published: January 2022

We study when every square matrix over an algebraically closed field or over a finite field is decomposable into a sum of a potent matrix and a nilpotent matrix of order 2. This can be related to our recent paper, published in Linear & Multilinear Algebra (2022). We also completely address the question when each square matrix over an infinite field can be decomposed into a periodic matrix and a nilpotent matrix of order 2
Energy Method for the Elliptic Boundary Value Problems with Asymmetric Operators in a Spherical Layer
Authors:   Institute of Computational Modelling SB RAS, Denisenko Valery V. , Nesterov Semen A.
Published: January 2022

Three-dimensional elliptic boundary value problems arising in the mathematical modeling of quasi-stationary electric fields and currents in conductors with gyrotropic conductivity tensor in domains homeomorphic to the spherical layer are considered. The same problems are mathematical models of thermal conductivity or diffusion in moving or gyrotropic media. The operators of the problems in the traditional formulation are non-symmetric. New statements of the problems with symmetric positive definite operators are proposed. For the four boundary value problems the quadratic energy functionals, to the minimization of which the solutions of these problems are reduced, are constructed. Estimates of the obtained quadratic forms are made in comparison with the form appearing in the Dirichlet principle for the Poisson equation

Authors:   Institute of Computational Modelling SB RAS, Kaptsov Oleg V.
Published: January 2022

In this paper, we consider the problem of formal iteration. We construct an area preserving mapping which does not have any square root. This leads to a counterexample to Moser’s existence theorem for an interpolation problem. We give examples of formal transformation groups such that the iteration problem has a solution for every element of the groups

A List of Integral Representations for the Diagonal of Power Series of a Rational Function
Authors:   Siberian Federal University, Senashov Artem V.
Published: January 2022

In this paper we present integral representations for the diagonals of power series. Such representations are obtained by lowering the multiplicity of integration for the previously known integral representation. The procedure for reducing the order of integration is carried out in the framework of the Leray theory of multidimensional residues. The concept of the amoeba of a complex analytic hypersurface plays a special role in the construction of new integral representations
Modeling of Anisotropy Dynamics of the Proton Pitch Angle Distribution in the Earth’s Magnetosphere
Authors:   Siberian Federal University, Smolin Sergei V.
Published: January 2022

Last years the attention to research of anisotropy of the charged particle pitch angle distribution has considerably increased. Therefore for research of anisotropy dynamics of the proton pitch angle distribution is used the two-dimensional Phenomenological Model of the Ring Current (PheMRC 2-D), which includes the radial and pitch angle diffusions with consideration of losses due to wave-particle interactions. Experimental data are collected on the Polar/MICS satellite during the magnetic storm on October 21–22, 1999. Solving the non-stationary two-dimensional equation of pitch angle and radial diffusions, numerically was determined the proton pitch angle distribution anisotropy index (or parameter of the proton pitch angle distribution) for the pitch angle of 90 degrees during the magnetic storm, when the geomagnetic activity Kp-index changed from 2 in the beginning of a storm up to 7+ in the end of a storm. Dependence of the perpendicular proton pitch angle distribution anisotropy index with energy E = 90 keV during the different moments of time from the McIlwain parameter L (2.26 < L < 6.6) is received. It is certain at a quantitative level for the magnetic storm on October 21–22, 1999, when and where on the nightside of the Earth’s magnetosphere (MLT = 2300) to increase in the geomagnetic activity Kp-index there is a transition from normal (pancake) proton pitch angle distributions to butterfly proton pitch angle distributions. That has allowed to determine unequivocally and precisely the anisotropy dynamics of the proton pitch angle distribution in the given concrete case. It is shown, that with increase of the geomagnetic activity Kp-index the boundary of isotropic proton pitch angle distribution comes nearer to the Earth, reaching L ≈ 3.6 at Kp = 7+

Connecting Homomorphism and Separating Cycles
Authors:   Siberian Federal University, Ulvert Roman V.
Published: January 2022

We discuss the construction of a long semi-exact Mayer–Vietoris sequence for the homology of any finite union of open subspaces. This sequence is used to obtain topological conditions of representation of the integral of a meromorphic n-form on an n-dimensional complex manifold in terms of Grothendieck residues. For such a representation of the integral to exist, it is necessary that the cycle of integration separates the set of polar hypersurfaces of the form. The separation condition in a number of cases turns out to be a sufficient condition for representing the integral as a sum of residues. Earlier, when describing such cases (in the works of Tsikh, Yuzhakov, Ulvert, etc.), the key was the condition that the manifold be Stein. The main result of this article is the relaxation of this condition

Modelling and Simulation of Deformation and Failure of Reinforced Concrete Beams under Four-Point Bending
Authors:   Khristianovich Institute of Theoretical and Applied Mechanics SB RAS, Belyaev Vasily A.
Published: January 2022

A new mathematical model for the four-point bending of reinforced concrete beams is developed and investigated. The model takes into account multi-modulus concrete behavior, nonlinear stress-strain relationships, and damage evolution. An algorithm for a numerical implementation of the model is proposed. The corresponding boundary value problem is solved by the hp-version of the least-squares collocation method in combination with an acceleration of an iterative process based on Krylov subspaces and parallelizing. Special attention is given to the influence of mathematical model parameters on the results of numerical simulation. The results are compared with experimental data and three-dimensional simulation. A satisfactory agreement is shown

Published: January 2022

The model of the frictional interaction of a fiber composite material with a rigid non- wearing body is proposed, which makes it possible to study the effect of the mechanical and strength characteristics of the fiber and matrix materials and the composite structure on its stress state, in particular, at the fiber-matrix interface. Analysis of the stress distribution in the subsurface layers of the composite was carried out for different values of the ratio of matrix to fiber materials hardness, the sliding friction coefficient and the distance between the fibers. For the known failure criteria of fiber composites, the conclusions about the effect of the structure and relative strength properties of a fiber (fiber bundle) and matrix on the pattern of subsurface fracture of the composite under sliding friction conditions are made

Published: January 2022

The paper gives insights into modeling and well-posedness analysis driven by cyclic behavior of particular rate-independent constitutive equations based on the framework of hypoplasticity and on the elastoplastic concept with nonlinear kinematic hardening. Compared to the classical concept of elastoplasticity, in hypoplasticity there is no need to decompose the deformation into elastic and plastic parts. The two different types of nonlinear approaches show some similarities in the structure of the constitutive relations, which are relevant for describing irreversible material properties. These models exhibit unlimited ratchetting under cyclic loading. In numerical simulation it will be demonstrated, how a shakedown behavior under cyclic loading can be achieved with a slightly enhanced simple hypoplastic equations proposed by Bauer

Authors:   Institute of Computer Aided Design RAS, Nikitin Ilia S. , Golubev Vasily I. ,   Moscow Institute of Physics and Technology (National Research University)
Published: January 2022

In this paper we consider the problem of dynamic loading of a deformable solid medium con- taining slip planes with nonlinear slip conditions on them. An explicit-implicit scheme was constructed for the numerical solution of the constitutive system of equations, which exactly reduces to correcting the stress tensor values after performing the elastic step. An implicit approximation of the constitutive relations containing a small parameter in the denominator of the nonlinear free term was used with the second order of the approximation. The correction procedure is applicable for those cases when the viscosity parameter of interlayers providing the sliding mode of the contact boundaries is not small. The solution of the problem of the seismic waves propagation in an inhomogeneous fractured geological massif in a two-dimensional case was obtained numerically
Synthesis of Higher Alcohols on Silver-promoted LaCo- and LaCoCu-Perovskites
Authors:   Boreskov Institute of Catalysis, Dokuchits Eugene V. , Minyukova Tatyana P.
Published: January 2022

LaCoO3 and LaCo0.7Cu0.3O3 perovskites supported on highly dispersed mesoporous silica KIT‑6 were impregnated with silver nitrate (nAg/nCo = 4/99 and 8/99). The phase composition of the initial samples and samples after catalytic tests in syngas conversion and catalytic characteristics have been investigated. The regularities of the transformation of samples in the process of reduction in a hydrogen-containing gas have been studied. It is shown that, for the LaCoO3 sample, with an increase in the silver content, the activity and selectivity for higher alcohols increase from 6 to 23 %. The maximum interaction of cobalt with silver is observed at a silver content of 4 %. At a higher content, part of the cobalt is reduced regardless of the influence of silver due to its faster agglomeration. This leads to a stronger amorphization of the reduced sample and a sharp increase in its activity. The LaCo0.7Cu0.3O3 sample exhibits a higher selectivity for higher alcohols (36 %) due to the effect of copper. Silver promotion of the sample allows achieving the maximum selectivity for higher alcohols of 56 % with a silver content of 4 %. A further increase in the silver content leads to a sharp decrease in the selectivity for higher alcohols (41 %) and the appearance of CO2 due to the saturation of copper-containing particles with silver and a decrease in the interaction of cobalt with copper

Authors:   AJA University of Medical Sciences, Pourhossein Mehran , Golaghaei Alireza , Khaghani Ramin , Paknezhad Babak
Published: January 2022

Ultrasound assisted emulsification microextraction (UAEME) as a new sample preparation method was optimized for the determination of permethrin in urine samples. Also, deep eutectic solvent was used as the extracting solvent instead of organic solvents in this method. In order to determine the optimal values, six main parameters were studied in different levels. Totally, 105 runs were performed using the one-variable-at-a-time method followed by high-performance liquid chromatography with a UV detector. Under the optimum conditions, the calibration curve for permethrin was linear in the concentration range of 5 to 500 μgL‑1 for urine samples. The accuracy and reproducibility of the introduced method were determined using the relative recovery (RR%) and relative standard deviation (RSD%) tests on the fortified urine samples. RR% and RSD% were found to be 96.3–101.7 % and 3.2–7.6 %, respectively. The limit of quantification and also the limit of detection were obtained 5 and 1 μg/L, respectively. In the present study, the DES-UA-EME technique was successfully developed for the extraction of permethrin from urine samples and subsequent quantification by high-performance liquid chromatography.In comparison to the other sample preparation methods, the proposed technique has the advantages of shorter extraction time, simplicity, and applicability in laboratories with less equipment

City as Flux: Interrogating the Changing Nature of Urban Change
Authors: Inam Aseem
Published: January 2022

What do we mean by the changing nature of urban change? First of all, in the 20th and 21st centuries, cities have been changing in different and dramatic ways, whether through grassroots mobilizations, through technological leaps, or through profit-driven speculations. Second, our understanding of how cities change has also been evolving, in particularly through empirical work that challenges the broad-brush universalizations of conventional thinking. The authors of the six selected articles take us through an around-the-world tour of cities and regions that range from Mulhouse in France to Dakar in Senegal to Las Vegas in the United States to Bogota in Colombia and beyond. Each author carefully examines the nature of urban change and how planners, developers, and citizens are either dealing with that change or even shaping it. Together, what the articles suggest is that we need a more fine-grained understanding of the city as flux in order to obtain better theoretical insights as well as urban practices that can better manage and ultimately shape urban change to benefit citizens, especially those who are marginalized.
A tanár-diák kapcsolat jellemzői a testnevelésben
Authors: Révész László
Published: January 2022

Jelen tanulmány célja a tanár-diák kapcsolat vizsgálata a testnevelés tanítása kapcsán. Az elmúlt időszakban a testnevelés tantárgy (testnevelés és egészségfejlesztés műveltségi/tanulási terület) szempontjából kedvező oktatáspolitikai döntések születtek. A mindennapos testnevelés (2012) bevezetése jelentős óraszám-növekedést hozott (ezáltal az egyik legnagyobb óraszámú tantárgy lett; 2011. évi CXC tv.), illetve a NAT 2020 és a kerettantervek új tantárgyi tartalmakat és módszertani megoldásokat is beemelnek. Az eredményes tanítási-tanulási folyamatnak számos összetevője van, ugyanakkor a szakirodalomban is eltérések mutatkoznak, hogy mely tényezők a legfontosabbak az eredményes és hatékony tanítás, tanulás megvalósításában (de Corte, 2010; Gutierrez & López, 2021; Halász, 2014; Óhidy, 2005). A testnevelés órán sajátos tanár-diák kapcsolat jellemző, ugyanakkor a testnevelő tanárok megítélése a saját szerepükről a tantestületben változó képet mutat. Hamar és munkatársai (2017) szerint a testnevelők úgy érzik, hogy a testnevelés státusza nem éri el a többi tantárgyét, valamint a testnevelő tanároké sem. Annak ellenére így gondolták a kutatásban megkérdezettek, hogy a mindennapos testnevelés a tantárgy korábbi „megítélését” is javíthatta volna. A mindennapos testnevelés bevezetésével kapcsolatos kutatások fókuszába elsősorban a megnövekedett óraszámmal járó változások hatásának vizsgálata került. Borbély (2019) összegzi a megjelent kutatásokat, melyből megállapítható, hogy leginkább a tartalomhoz (tananyag) és a testnevelő tanárokhoz kapcsolódtak a felmérések. Kisebb arányban jelentek meg a tanulói és a tantárgyi vizsgálatok. A kutatások egy része a tanulók pszichomotoros (kondicionális, koordinációs) képességeinek fejlődésére tért ki (pl. Szakály et al., 2019; Vári, 2015), illetve a NETFIT által mért egészségközpontú felmérések jelentették a kutatások irányait (pl. Csányi et al., 2015, 2016; Erdei, 2015). A tantárgyhoz kapcsolódó neveléstudományi szempontú vizsgálatok, melynek fókusza a testnevelő és a tanuló, eddig elhanyagolható mértékben jelentek meg. A témaválasztásban emiatt szerepet játszik, hogy a hazai tantárgyspecifikus kutatások száma kevés, illetve az empirikus kutatáson alapuló, a tanár-diák kapcsolatra fókuszáló kutatások szinte teljesen hiányoznak a hazai neveléstudományi szakirodalomból a testneveléshez kapcsolódóan. Vizsgálatunk során ezért arra vállalkoztunk, hogy a témát neveléstudományi keretek között elemezzük, melyben a központi kérdés a tanár-diák kapcsolat jellemzőinek feltárása a testnevelés aspektusából, a diákok szemszögéből.
The Future Roles of Journalism: Where Does Ukraine Stand in Europe?
Authors:   Windesheim University of Applied Sciences in Zwolle, Drok Nico
Published: January 2022

The changing societal context of professional journalism has brought many challenges for 21st century journalism to the forefront. The transition from a sender-oriented mass media model to an interactive network model is still in progress, but there can be little doubt that journalism will have to adapt to the new infrastructural reality in order to avoid a deepening of the current crisis in journalism. In the news industry innovation is mainly defined in terms of technology and commerce and often the cultural component is missed. However, the transition to the network model not only requires new business models and platforms, but also a new balance in the various roles of professional journalism. Although research shows changes for the better, there are no clear-cut indications that in daily practice an ambitious restructuring of the goals of journalism has yet taken place. Instead, interesting new technologies are often used for achieving traditional ends: old journalism in new digital bottles. But journalism is of central importance to contemporary society and its future cannot be left to its current producers alone. In the process of renewing the culture of journalism, education plays a central role. Students will have to learn to master the essential routines of their future profession, but next to that it becomes more important that journalism students learn to critically reflect on the future role of journalism in society. In this article the views of Ukrainian teachers on the roles of journalism are compared to those of their colleagues in other parts of Europe. It concludes that there are similarities, but also a divide.
Coverage of the Domain Problem of Scientific Results’ Approbation in Scientometric Databases Scopus and Web of Science
Authors:   Taras Shevchenko national University of Kyiv, Romakh Oksana
Published: January 2022

The article is devoted to the study of problematic aspects in the publication of materials in journals indexed in the scientometric databases Scopus and Web of Science by scientific and scientific-pedagogical workers. The Ministry of Education and Science of Ukraine believes that it is not necessary to rely on quantitative indicators (it is even necessary to abandon them), and the place of publication of the article should be unimportant. At the same time, the Ministry of Education and Science establishes norms according to which it is impossible to obtain a scientific title, academic degree and be a member of a specialized scientific council without publications in scientometric databases Web of Science and / or Scopus. In the field of social communications (journalism) the problem is exacerbated by the fact that in Ukraine there are no professional journals that would be included in such scientometric databases. The purpose of the study is to identify and describe the components of the modern problem of approbation of scientific results in scientometric databases Scopus and Web of Science (in the field of «journalism»). To achieve this goal, we set the following tasks: to analyze the regulations, which contain instructions / advice / guidelines / standards for publication in the journals of the database Scopus and Web of Science; to identify the attitude of scientific and scientific-pedagogical workers working in the field of «journalism» to the problem of approbation of scientific results in such journals; identify motives and obstacles to the publication of articles in indexed journals. The main result of the article is to highlight the following problematic aspects: ambiguous position and strategy of the state to measure the quantity and quality of scientific papers; lack of encouragement of scientific and scientific-pedagogical workers to publish in indexed publications with simultaneous compulsion to publish there; high cost of publication and lack of any support from the state in publishing articles; low quality of scientific works submitted to such publications and non-recognition of this problem by the community.

Published: January 2022

In the research were analyzed visual techniques that were used to fill the content of Ukrainian TV channels in the period from the beginning of December to the end of January. The Christmas and holiday season are not officially included in a separate category of TV programming, but the season is fundamentally important for attracting the viewer’s attention and for setting the further price of airtime for advertisers. The article is one of the first attempts to consider this aspect broadly/extensively and to outline the current vectors of studying the specifics of the program content of TV channels in the period of Christmas and holiday season, therefore this article is promising for the applied social communications area. In order to describe the main visual techniques, that are used in television content, the authors emphasize on their diversity, also they leave space for the further analysis of other nonverbal and verbal elements of the screen communication, that are used during festive period. Researchers have selected the TV channels logos, the program broadcast in the night from December 31.12.20 to January 01.01.2021, as well as other screen products of the different genres, telefilms and movies, that were shot and presented on TV broadcast in different years. Among the main research methods were used the following: content-analysis, which contributed to a thorough study of the software network of TV channels broadcasting, observation and comparison, which helped to outline the common and different characteristics of software products and broadcasts in general, induction method, which helped to form the key screen concepts. The suggested conclusions provide grounds for the statement, that the choice of content for filling TV channels during festive season is based on commercial inquiries, creative and technological resources of the television producers. In addition, the authors mention the segment of Christmas and New Year congratulations of head of state as promising for the further research.
REFORMING THE PENSION SYSTEM OF UKRAINE TAKING INTO ACCOUNT THE EXPERIENCE OF POLAND
Authors:   Taras Shevchenko national University of Kyiv, Kravchenko T. , Moroz O. ,   Taras Shevchenko national University of Kyiv
Published: January 2022

The state, stages of formation and problems of the pension system of Ukraine are considered. The main directions of pension reform are identified, taking into account the experience of Poland. The attitude of citizens to the current state and readiness for changes in the pension system of Ukraine is analyzed. The survey showed that the respondents are ready and support the reform of the Ukrainian pension system and the introduction of the accumulative component, but there is a big problem in the form of distrust of private pension funds and private insurance companies. It is determined that the pension system is no longer able to withstand the load and requires changes in the near future. Analysis of the pension system has shown that it has always been formed taking into account only short-term objectives, which makes it ineffective in strategic terms. It is substantiated that without the growth of the welfare of the population, the de-shadowing of the labor market and the introduction of accumulative pension insurance, the financial condition of the Ukrainian solidarity pension system will deteriorate every year. However, along with the expected positive effect of the introduction of the accumulative component in Ukraine, there are also risks, as fluctuations and instability of the domestic economy may lead to deterioration of the banking sector and insurance companies, which will reduce investment returns in the system or even partial loss of pension savings. Two development scenarios (pessimistic and optimistic) for the pension system of Poland and Ukraine are analyzed. It is determined that for the successful reform of the old solidarity system of Ukraine into a cumulative one it is necessary to: ensure sustainable GDP growth; create a centralized information system for collecting contributions; to personify and register all insured persons in the Pension Fund; identify the needs for qualified personnel, equipment and funds needed to meet the requirements of the new system; provide absolutely all conditions for the effective implementation of the private pension system.
