The impact of shadow banking on nonfinancial firms listed on the Ho Chi Minh Stock Exchange (HOSE) – Evidence from Vietnam
Authors: Le Thy , Nguyen Thi Kim Ngan , Hoang Dieu Thi
Published: February 2024

This paper examines the effect of shadow banking activities on the performance and risk-taking of 339 Vietnamese nonfinancial firms listed on the Ho Chi Minh Stock Exchange (HOSE). Using manually gathered data on firms' shadow banking activities from 2009 to 2021, the expansion of shadow banking is found to have a negative effect on the overall financial soundness of the securities companies, in particular negatively affecting performance and increasing the risk tolerance of companies. We present empirical findings about several aspects of shadow banking activities, including entrusted loans, entrusted investments, private lending, leasing, and commercial credit in this study. While the majority of shadow banking operations could have a negative impact on a firm's performance, we have discovered that commercial credit grants were crucial in reducing the COVID-19 pandemic's adverse effects on businesses, highlighting the need for financial stability in times of crisis. According to our results, the risk of shadow banking activities, which have consequences for policymakers and caution for nonfinancial enterprises, must be taken into consideration.

Objective

Many studies have explored the relationship between childhood trauma and internet addiction from different theoretical perspectives; however, the results have been inconsistent. The purpose of this meta-analysis was to examine the relationship between childhood trauma and internet addiction.

Methods

The PubMed, Web of Science, Embase, CNKI, Wanfang and VIP electronic databases were searched to identify studies examining the correlation between childhood trauma and adolescent internet addiction. The databases were searched from inception to December 31, 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Then, Stata 17.0 software was used to perform meta-analysis.

Results

This study was registered on PROSPERO (CRD42023388699). A total of 19 studies involving 21,398 adolescents were included in this meta-analysis. The random effects model was used for pooled analysis, and the results revealed a strong positive association between childhood trauma and internet addiction (r = 0.395, 95% CI [0.345, 0.442]). The relationship between childhood trauma and internet addiction was moderated by sample size, survey area, and internet addiction measurement tools. There were significant differences between the associations based on the various child trauma measurement tools and study quality scores. However, interstudy heterogeneity was not significantly affected by study year, sample source, or participant age.

Conclusion

Internet addiction is positively correlated with childhood trauma. Therefore, it is extremely important for parents to provide a good growth environment during childhood to enhance the physical and mental development of adolescents. A warm family atmosphere helps individuals develop a healthy personality, thereby reducing or preventing the occurrence of internet addiction. Due to the limited number and low quality of the included studies, the above conclusions need to be verified by additional high-quality studies.
Pesantren dan pluralisme: Analisis Peran Pesantren Sebagai Katalis Pribumisasi Islam di Indonesia
Authors: Hakim Lutfi
Published: February 2024

Pesantren in Indonesia are a representation of Nusantara Islam which prioritizes tolerance, affirms Islam rahmatan lil 'alamin, with the ideology of tawazun, tawasuth, tasamuh, and i`tidal. Pesantren are ready to provide solutions to the community and are ready to spearhead the cultural Islamic movement and the power of civil society by combining traditional religious knowledge with modern science. Education in pesantren is provided by a representative cleric or kiai who becomes a mentor teacher and role model for students in life. Pesantren education is organized in an orderly manner and takes a long time so that students can gain an in-depth understanding of the essence of everything, making it easier to distinguish between right and wrong. Pesantren since its inception have been very close to the community, because this institution was founded based on a community approach. The presence of pesantren is a carriage that guards the Unitary State of the Republic of Indonesia which is full of multi-racial, ethnic, religious and cultural aspects. The concept of indigenizing Islam in the archipelago has become a jargon for pesantren that must be preserved so that Indonesia, which is multi-religious and cultural, remains safe and does not fall apart. From this short article, the writer wants to see how Islamic boarding schools see and behave towards the problem of religious plurality in Indonesia, which in fact cannot be denied.
PERFORMANCE ANALYSIS OF ACHIEVABLE BIT RATES IN RIS-ASSISTED MASSIVE MIMO NETWORKS AT 28 GHz BAND
Authors: Sharini D. L. , Kanthi M. , Dilli Ravilla
Published: February 2024

Reconfigurable intelligent surface (RIS) technology is a smart way of controlling the radio signal propagation to improve the capacity and coverage of wireless networks. RIS tunes the phase shifts of the incident signals in a dynamic fashion. Channel modeling is an important aspect in RIS-based mmWave communication for the next-generation wireless networks. However, to achieve maximum benefit from RIS-assisted wireless systems, it is essential to provide accurate channel state information (CSI). But, it is very challenging to get accurate CSI because of large number of RIS elements, their passive nature, and the training overhead involved during the channel estimation. To overcome
the higher training overhead, in this article we aimed to take advantage of the correlation and sparsity
of channels in RIS-assisted channel estimation. The objective of this work is to propose a simplified
channel model for the RIS-assisted physical channel of a massive multi-input-multi-output (mMIMO)
wireless communication system and analyze its performance in terms of transmitted powers, MIMO
configurations, and achievable bit rates. The simulated results proved that the strategic placement of
RIS with optimal phase shifts and optimal MIMO configuration can enhance the maximum achievable rate. The achievable rates of the proposed channel modeling are compared with the existing state-of-the-art methods to prove its efficiency. Also, the combination of mMIMO technology along with RIS-assisted communication provides degrees of freedom in terms of signal coverage, energy consumption, and system complexity.

Harmonization implies a coordinated policy of legal regulation, including on the basis of the actions of the EAEU bodies, to the extent that this is important for achieving the goals of the EAEU provided for by the agreements. There are many positive results of integration cooperation between Kyrgyzstan and other EAEU countries, but there are not only achievements but also difficulties when the organization of joint contractual legislative activities of the EAEU countries is often late. For example, there are protracted procedures for discussing the general principles of banking regulation and control, in particular, the general conditions for the creation and operation of international financial centers in the EAEU, etc.

Religion, as historical experience shows, in such cases offers society the deepest and most stable spiritual and moral foundations for its further existence. Neither science nor philosophy knows more ultimate grounds, although both, of course, also offer not only their own explanations for what is happening but also their own ways out of the current situation. Moreover, morality in itself and the ethics that studies it, as well, have always been and will be a problematic field, where there are no ready-made answers. This problem is always associated with the need for personal choice, one's own responsibility, and the lack of ready- made unambiguous answers to the ultimate questions of human existence, which, of course, complicates the already difficult life of an ordinary person in an era of transformations and crises.

The article is devoted to the analysis of the problem of improving the training of specialists in providing psychological assistance to internally displaced persons. The full-scale invasion of Russian troops into Ukraine on February 24, 2022 caused a new wave of forced relocation of millions of Ukrainian citizens who, saving their lives and family members, were forced to move in search of safe corners and adapt to the new realities of today. Psychological assistance in the conditions of war for both children and adults, although it is not new for many specialists in the psychological field, but it definitely requires a responsible attitude, high professionalism in the prevention of the consequences of stress and distress, acute emotional states, experiencing grief and loss, prevention of various manifestations of interpersonal conflicts, violence in the educational environment, as well as sensitivity and respect for each individual. The problem of the organization of psychological assistance to families and children who are in difficult life circumstances as a result of military operations is revealed, which acquires a new vector: from response in the format of working through crisis emotional states, stabilization of the state to psychoemotional recovery. This format involves systematicity, structure, psychoeducation, and the organization of psychological interventions based on the collected anamnesis about the family or person. The work highlights the experience of conducting the training course "Modern methods of providing psychological assistance to internally displaced persons in today's realities" by the employees of the Psychological Center of Melitopol State Pedagogical University named after Bohdan Khmelnytskyi in order to improve the professional competencies of psychologists in providing psychological assistance to internally displaced persons. According to the results of which, the participants of the training course improved their professional skills in applying modern methods and tools of psychological counseling and psychotherapy, which will contribute to more effective professional activity in restoring the psychological state of internally displaced persons in war conditions.
THE HOLODOMOR OF 1932-1933 IN UKRAINE (ACCORDING TO THE DOCUMENTS OF SKOROPADSKYI’S ARCHIVE IN THE CENTRAL STATE HISTORICAL ARCHIVE OF UKRAINE)
Authors:   Central State Historical Archive of Ukraine (2006-2015), KUGAI Vitalii
Published: February 2024

The article analyzes an unknown body of documents on the history of the Holodomor in Ukraine in 1932-1933, preserved in the Skoropadskyi Fund - the archive of the family of the last hetman of Ukraine, Pavlo Skoropadskyi. For a long time, this archive was kept in the private property of P. Skoropadsky's daughter YElizaveta Skoropadska, and later in the East European Institute named after V. Lipinsky in Philadelphia (USA). In 2006, the archive was sent to the Central State Historical Archive of Ukraine (Kyiv), where it was at the stage of scientific and technical development and became available to researchers only at the end of 2022. Documents on the history of the Holodomor were deposited in the fund thanks to YE. Skoropadska, who from 1933 headed the Committee for Aid to the Starving in Ukraine, which provided material aid to the victims of the famine in Ukraine, conducted organizational work to collect funds for the starving, and disseminated information about this famine in the world. The archive of E. Skoropadska includes hundreds of documents with a total volume of more than 6,300 sheets. This is the largest archive of documents about the Holodomor of 1932-1933 in Ukraine and the world. It contains letters from witnesses of the Holodomor, testimonies of various people, articles, clippings from newspapers and magazines, etc. The article concludes that the analyzed documents indisputably prove the artificial nature of the famine of 1932-1933, which was planned and carried out by the communist regime of the USSR and became a terrible crime against the Ukrainian people. During the Holodomor in Ukraine and the Kuban, where mostly representatives of the Ukrainian ethnic group lived, whole villages died and millions of people died. The collection of archival documents by YE. Skoropadska about the Holodomor of 1932-1933 in Ukraine is unique for Ukrainian historical science. These materials are the most complete, integral and voluminous body of documents collected "on hot tracks", which have no analogues in Ukraine and the world.

Published: February 2024

The work is devoted to the empirical analysis of age shifts within the framework of the factor model of autism for preschool children. In the 2020–2022 studies, we obtained a factor model of autism and identified 4 vectors of autism — typical subtypes of ASD in 3–4 years old children. Among them are: 1) difficulties in establishing emotional contact, expressing one's emotions and decoding other people's emotions in the context of social interaction; 2) sensory disintegration; 3) impairments in verbal and nonverbal communication and social skills; 4) hyperactivity, including excessive movements, motor disinhibition and restless behavior. It should be emphasized that the first three vectors correspond to the core symptoms of ASD in accordance with the DSM-5. While the hyperactivity factor goes beyond the main symptoms of ASD. In this paper, a comparative analysis of the severity and stability of symptoms was carried out within the framework of a 4-factor model of autism for 3–4 and 5–6-year-old children with autism. Sensory and communication impairments have been found to decrease with age, however, emotional impairments and hyperactivity remain at a high level. The theoretical foundations of emotional disorders and hyperactivity in children with ASD are analyzed in detail. Brief practical recommendations are presented for effective early intervention in order to improve the potential trajectory of development of preschool children with ASD.

Endometriosis is a chronic multifactorial disease that affects one in ten women of reproductive age. Genetic, endocrine and immunological factors play an important role in the pathogenesis of endometriosis. In recent years, an increasing number of studies have been devoted to the role of vaginal microbiota in the pathogenesis of endometriosis. However, the role of viral infections, such as papillomavirus and herpesvirus infections, in the development of the disease has not been sufficiently studied. The review highlights current ideas about the role of human papillomavirus and herpesvirus infections in the genesis of endometriosis. The data obtained have convinced us of the need to further search for new relationships between papillomavirus and herpesvirus infections, microbiota of reproductive organs and pathogenesis of such a complicated disease as endometriosis.

Background: The etio-pathogenesis of growth failure in transfusion dependent thalassemia major (TDTM) children is mainly because of chronic anemia, iron overload and endocrine complications. Aim was to determine the association between anthropometric measurements with pre-transfusion haemoglobin in TDTM children.
Methods: Present cross-sectional study included total 55 children between 5-18 years of age who were diagnosed as TDTM. Mean pre transfusion hemoglobin of last 1 year was obtained from previous medical records. Anthropometric measurements like weight in kg and height in cm measured while body mass index (BMI) was calculated using standard formula in each patient. Weight for age, height for age, and BMI were plotted on WHO 2006 and Indian academy of paediatrics 2015 combined growth charts in terms of percentile. Data was analysed statistically.
Results: Total 55 children of TDTM between 5-18 years of age were studied. The mean age was 10.42(4.07) years. The mean weight (kg), height (cm) and BMI was 23.76 (7.5), 123.94 (18.13) and 15.24 (1.76) respectively. Fifty-one (92.73%) children were having BMI less than 3rd centile (Underweight). Forty (93.02%) and 11 (91.66%) children between age group of 5-10 years and more than 10 years were underweight and was statistically significant (p<0.05). Total 50 (94.33%) children were having mean pre transfusion hemoglobin below 9 gm/dl who were underweight which was statistically significant.
Conclusions: Low pre-transfusion hemoglobin is one of the risk factors for growth failure in children with TDTM and it should be maintained above 9 gm/dl may for normal growth in children with TDTM.

Published: February 2024

Preeclampsia is a disease characterized by hypertension, proteinuria, and edema that occurs after the 20th gestational week. It is among the most important reasons for maternal/perinatal morbidity and mortality. Although many studies have been carried out, the pathophysiology of the disease is not fully known. Many methods have been proposed for evaluating risk factors leading to preeclampsia. In the past, the methods used to predict preeclampsia have usually been focused on non-biochemical markers, but nowadays there is a shift towards biochemical markers. Recently, many biochemical agents have been started to be used in the prediction of preeclampsia. In this study, the evaluation of some serum biomarkers in the follow-up preeclampsia was aimed. Serum nesfatin, ezrin, placental protein 13, hypoxia-inducible factor 1-α subunit (HIF1A), and neuropilin 1 levels were examined with the ELISA method. In the study, 90 samples taken from subjects, including pre-treatment preeclampsia (n =35), post-treatment preeclampsia (n = 35), and healthy control (n = 20) groups were evaluated. The data obtained from the study was analyzed with SPSS 22.0. As a result of the statistical analysis, pre-treatment nesfatin-1, and ezrin levels were found significantly lower than post-treatment and the healthy control group and HIF-1A levels were found significantly higher. As a result of these analyses, pre-treatment and post-treatment PP13 levels were found to be significantly higher than the healthy control group.

Considering the results obtained from the study, we can say that nestin, ezrin, HIF1A, PP13, and NRP1 are important biomarkers for predicting preeclampsia.
Effects of kappa-opioid agonist U-50488 and p38 MAPK inhibitor SB203580 on the spike activity of pyramidal neurons in the basolateral amygdala
Authors: Kalitin Konstantin Y. , Spasov Alexander А. , Mukha Olga Y.
Published: February 2024

Introduction: Kappa-opioid receptor (KOR) signaling in the basolateral amygdala (BLA) underlies KOR agonist-induced aversion. In this study, we aimed to understand the individual and combined effects of KOR agonist U-50488 and p38 MAPK inhibitor SB203580 on the spiking activity of pyramidal neurons in the BLA to shed light on the complex interplay between KORs, the p38 MAPK, and neuronal excitability.
Materials and Methods: Electrophysiological experiments were performed using the patch-clamp technique in the whole-cell configuration. Rat brain slices containing the amygdala were prepared, and pyramidal neurons within the BLA were visually patched and recorded in the current clamp mode. The neurons were identified by their accommodation properties and neural activity signals were amplified and analyzed. Using local perfusion, we obtained three dose-response curves for: (a) U-50488 (0.001–10 μM); (b) U-50488 (0.001–10 μM) in the presence of SB203580 (1 μM); and (c) U-50488 (0.01–10 μM) in the presence of SB203580 (5 μM).
Results: After the application of U-50488, pyramidal neurons had a higher action potential firing rate in response to a current injection than control neurons (p<0.001). The dose-dependent curves we obtained indicate that the combination of U-50488 and SB203580 results in non-competitive antagonism. This conclusion is supported by the observed change in the curve’s slope with reduction in the maximum effect of U-50488. Thus, it can be assumed that the increase in spike activity of pyramidal neurons of the amygdala is mediated through the beta-arrestin pathway. When this pathway is blocked, the spike activity reverts to its baseline level.
Conclusion: Our study found that the KOR agonist-induced spiking activity of the BLA pyramidal neurons is mediated by the beta-arrestin pathway and can be suppressed by the application of the p38 MAPK inhibitor SB203580.

Competitors’ probability distribution law, state scale invariance and linear growth models
Authors:   Keldysh Institute of Applied Mathematics, Podlazov Andrej
Published: February 2024

The scale invariance is one of the distinguishers of the holistic behavior. Self-organized critical systems and systems with coherent noise giving examples of the scale invariance consist of essentially nonlinear elements. On the contrary, linear growth models with scale invariant properties are formulated in the paper. Since the wholeness can’t arise from linear schemes, it is initially included in thе rules of the proposed models by means of using the information about the cumulative characteristics оf the system. The presence of such «seed оf the holistic properties» is quite enough for the distribution of system parts sizes to be power-law. Besides that the questions of statistical samples processing for the construction of rank dependences, the analysis of the role of their parameters and the qualitative properties of systems described by power law probability distributions are considered in the paper.

The paper considers the formation оf coherent structures in а population of excitable systems driven by noise. We focus оn two effects. (i) A one-dimensional lattice with аt least one inhomogeneous unit demonstrates noise-induced excitation waves. The degree оf coherence in such а spatial structure саn be enhanced by tuning the noise intensity. (ii) A random distribution оf the parameters responsible for the excitatory properties and the interaction strength leads to self-organization in the form of cluster synchronization.

Symmetrically coupled nonlinear oscillator systems demonstrating transition to chaos via a sequence of period-doubling bifurcations under the control parameter variation exhibit various types of mutual synchronization. For these coupled systems, with dissipatively coupled logistic maps, we consider a hierarchy of possible oscillation types using the magnitude оf the time shift between subsystem oscillations аs а basis for multistable states classification. For oscillation states and their basins of attraction the ways of evolution are studied under nonlinearity and coupling variation. Obtained results are compared with those of physical experiment with a system of coupled, periodically driven nonlinear resonators.

We investigate numerically the influence of asymmetry оn synchronous chaos in the system of dissipatively coupled quadratic maps. It is shown that the synchronous chaotic attractor becomes fractal after the loss оf transversal superstability in the asymmetrical system. Correlation dimension of the attractor demonstrates nonmonotonic dependence on the coupling coefficient near the synchronization boundary (at the coupling decrease).

Authors:   P. G. Demidov Yaroslavl State University, Brjuhanov Jurij
Published: February 2024

Free oscillation and oscillation under a constant level input signal in low-frequency and high-frequency filters are considered. We use fixed point numbers in additional code. The method of one-dimensional point mapping is applied. Dynamical regimes are characterized by probabilistic diagrams. Expressions for most probably oscillation in the filter’s output with arbitrary numbers of quantization levels are defined. Given methods may be used for quantization effects investigation in the first-order digital filters with representation of the numbers in direct, inverse and additional code with rounding and truncation.

Background: After rice harvest, the majority of farmers in Manipur leave their land fallow without planting anything, despite the fact that it has a great deal of potential for growing a second crop in the rabi season with the remaining moisture and nutrients. One of the most crucial options for Manipur’s farmers is green pea, which not only boosts their revenue but also makes use of the nutrients and residual moisture in the soil. The current fertilizer application system ignores the carryover effect of the manure or fertilizer applied to the previous crop and instead bases its decisions on the nutritional requirements of the specific crop. Applying organic sources of nutrients to the previous crop greatly benefits the following crop. In light of the aforementioned considerations, an experiment was set up to determine whether the foliar application of nano fertlizers and organic source of nitrogen in the previous kharif rice crop had any lasting effects on the productivity of the following green pea crop. Methods: A field experiment was conducted during the kharif and rabi season of 2020-21 and 2021-22 at Hiyanglam Mayai Leikai in the Kakching district of Manipur, in order to research the residual effect of foliar application of nano fertlizers and organic source of nitrogen on the productivity and economics of zero tilled green pea in rice- green pea cropping sequence. A factorial randomized block design (FRBD) with three replications was used to set up the experiment. Result: The pooled data showed that vermicompost @100% RDN had the highest growth and yield characterictics over the vermicompost @ 75% RDN and 50% RDN. The combinations of nano NPK @ 1.5% + 100% RDN through vermicompost resulted in the highest increase growth and yield attributing characters of green pea and lowest was observed in the control + @ 50% RDN treated plot.

Critical reflection of the system approach to the study of formal logic and justification for mathematics interaction
Authors:   Belarusian State University of Informatics and Radio Electronics, Mikhailova Natalia V.
Published: February 2024

It should be noted that many modern works on logical research use a complex technical apparatus, which can only be understood by a well-prepared logic, it is impossible without studying mathematics. On the other hand, feedback from logic in the study of mathematics is important, since logical principles are intrinsically present in the basis constructions of mathematics and in mathematical logic. The principles of logic are adopted in mathematics in order to develop mathematical thinking through critical reflection, although formal logical analysis does not always reflect the real rules of mathematical argumentation. Understanding this contributes to the fundamentality of university mathematical education, as well as the need for a systematic approach to justification for mathematics.
Communication in the condition of networking society: Potential of actor-networking interaction
Authors:   National Research Saratov State University, Kvas Anna Yu.
Published: February 2024

Introduction. One of the most important conditions for the existence of a network as an organizing principle of social existence is the process of multidimensional communications. Networks, as opposed to hierarchical systems, make their existence possible only in the discourse of interactive communications. Main part. In the article, the author offers a socio-philosophical analysis of the existence of communication in a networked society from various methodological positions. In the course of the study, it becomes clear that the networking of communications transforms them at various levels: digital, socio-political, anthropological, ethical. Conclusion. In the conclusion of the article, the author concludes that in the conditions of a network society, communication processes are undergoing serious changes. The multidimensionality and openness of the communication systems of the network society are directly determined by the very nature of the network, its plasticity, flexibility and variability, which we observe today.
The three dimensions of urbanization and the summary and prospect of China’s urbanization path selection
Authors:   Nanfang Collage, Zhang Hailun
Published: February 2024

China has implemented the policy of reform and opening up for 40 years. Under the infl uence of this policy, China’s urbanization has made great development and progress. In the index of population urbanization, the most obvious progress has been made, both the number of cities, the number of urban population, and the urban area have greatly increased, changing the face of ‘rural China’ in the past. However, through in-depth and comprehensive analysis, especially the multidimensional analysis of urbanization, we can fi nd that there is a big gap between the quality and quantity of China’s urbanization in the two dimensions of behavioral urbanization and structural urbanization, that is, ‘the quantity is large but the quality is not high’. This is an issue that China needs to pay attention to in the next stage.

Published: February 2024

The article is devoted to the study of the space of the sky, which plays a significant role in the creation of the myth about the poet, poetry, creative gift. The originality of the author’s interpretation of the mythologems of the sun, moon, stars is studied. Mythopoetic imagery and mythological motifs form the basis of M. Mokaev’s artistic thinking. In the poetic texts of M. Mokaev there are heavenly images of various etymologies: mythological, religious. Considering them allows us to discover one of the key motives of his lyrics — the desire for an ideal. Symbols of heavenly bodies accompany the theme of creativity, love, friendship. The figurative and associative features of heavenly symbols are determined, the specificity of individual thinking is revealed, and the connection with mythological, religious, literary and philosophical foundations is established. The originality of the author’s interpretation of the mythologems of the sun, moon, stars is studied. The originality of metaphorization is revealed, the specificity of national artistic thinking in the poetry of M. Mokaev is revealed. The main tasks are to identify intertextual connections, allusions, reminiscences in order to clarify the mythological sources of M. Mokaev’s cosmogonic system. The work focuses on the main themes and motifs of the lyrics; on the study of poetic handwriting and artistic and stylistic features. As a result, the main images and motifs associated with the space of the sky are identified, the degree of influence of archetypes, mythologems, nominological elements, ornithogenic images (conditioned by the ideas of ascension) on the semantic field of the main concepts is revealed. For the reliability of the results of the study, we tried to cover all periods of the writer’s legacy associated with the identified issues.
Pushkin’s artistic iconography in small prose by T. Tolstoy
Authors:   Krasnoyarsk State Pedagogical University named after V.P. Astafiev, Kovtun Natalia V. ,   F.M. Dostoevsky Russian Christian Humanitarian Academy
Published: February 2024

The Pushkin myth in the works of Tatiana Tolstoy has been studied in sufficient detail in criticism and literary criticism, the analysis of the author’s stories in this context becomes the subject of scientific reflection much less often. Meanwhile, the concept of Pushkin’s myth in the key novel “Kys” (2000) is based on the artistic discoveries made by the author in the stories. The key place in this paradigm is occupied by the “Plot” and “Limpopo”, which presents the cartoon iconography of the poet, including the main points of his biography: birth, duel, death and an attempt (re)incarnation in the reality of the twentieth century. With all the historical and biographical, ironic and tragic elements of the poet’s image, he retains elusiveness, mystery, he is read as a force capable of freeing Russia from the curse of the revolution, returning to the original, archaic meanings of poetic utterance as such. Pushkin’s narrative is included as the most important component in the narrative manner of T. Tolstoy herself: from direct quotations, reminiscences, allusions, travesties, palimpsest to understanding.
