The system of sustainability factors of the fuel and energy complex of the regional economic system and improving the management of these factors in the regions of Russia
Authors: Zemlyacheva Ekaterina A.
Published: January 2024

The study is devoted to the definition of a system of sustainability factors for the fuel and energy complex of the regional economic system, as well as the development of recommendations for improving the management of these factors in the regions of Russia. Based on the provisions of the Systemic Approach, econometric modeling and a comprehensive analysis of the influence of potential factors identified in the literature on the sustainability of the fuel and energy complex of modern regional economic systems around the world are carried out. The international experience of 120 countries in 2022 is projected onto Russia and compared with Russian regions. As a result, a system of factors has been formed, including the electrification factor, the clean energy availability factor and the carbon emission factor in cement production, which increases the predictability and manageability of the sustainable development of this system. The barriers to the sustainable development of the fuel and energy complex in the regions of modern Russia are identified, firstly, the incomplete availability of clean energy (90 %), which, however, is significantly higher than the average for the international sample (76.95 %). Secondly, a large amount of CO2 emissions from the combustion of fossil fuels and the production of cement (10.81 tCO2 per capita). The prospect for the period up to 2025 is disclosed and recommendations are proposed for improving the management of selected key factors for the sustainable development of the fuel and energy complex in the regions of Russia. The practical significance of the article is explained by the fact that the author’s recommendations proposed in it on improving the management of selected key factors will ensure
Comparative analysis of the carbon market and the carbon tax mechanisms efficiency to achieve the goals of the global carbon footprint reduction
Authors: Zavyalova Elena B. , Li Jiacheng
Published: January 2024

The environmental agenda is decisive in the formation of the world economy at the present stage. The need for a green transition is rarely questioned by scientists. However, there remains a wide range of opinions about which instruments are the most effective in achieving the set goals of reducing the carbon footprint. The most popular mechanisms today are the carbon market and carbon tax mechanisms. Aim of the research was using modeling, literature analysis, and deduction methods to compare the similarities and differences between the basic principles of applying a carbon tax and a carbon market mechanism, the authors of the article identify the advantages and disadvantages of both approaches. The results of the research showed that the carbon market mechanism has obvious advantages such as flexibility, cross-industry and crossterritory coverage, and relative benefits for companies compared to a carbon tax mechanism. At the same time, the carbon tax mechanism has the obvious advantage of low management costs and wide coverage, but, on the other hand, these advantages are offset by potential inefficiencies and high “cost” for companies. The analysis of the policies of large countries with large carbon emissions over the past 2-3 years shows that they are more likely to introduce elements of the carbon market to reduce emissions. Based on the theoretical analysis of the main characteristics of the carbon market and carbon tax, as well as their advantages and disadvantages, the authors urge not to be limited to one of the options, but to use both mechanisms simultaneously. In particular, the carbon market should be the main mechanism when the goal is to create more incentives to actively reduce carbon emissions, while carbon tax policies can be an additional measure to incentivize or “punish” those enterprises that exceed emission standards, also, the carbon tax will help to involve those industries that, for various reasons, cannot be represented on the carbon market.
Analysis of the chemical crop protection market in Russia

Published: January 2024

The research is devoted to the analysis of the current state of chemical crop protection market in Russia. Significant industry growth has occurred in last decade due to the attractiveness of agriculture as an export-oriented industry. Russian agricultural products are in stable demand all over the world. Countries in the Middle East, South-Eastern Asia and Africa with constantly growing population rely on foodstuff import, including from the Russian Federation. Thus, country makes a significant contribution in a global food security. However, in order to develop and increase competitiveness, Russian farmers need to intensify crop production. One of technological improvement elements, which let growers to get sufficient yield and quality, is application of innovative chemical crop protection products. Pesticides help farmers struggle with crop diseases, pests and weeds, as well as minimize adverse climate factors in some cases. Agrochemicals market in Russia is represented not only by foreign players, but by domestic manufacturers as well. Market share of these two groups in value terms of market players is approximately equal. However, it’s worth mentioning, that like in many other industries, this sector is heavily dependent on import inputs. Major part of components for local pesticide production are imported and key technological process is constrained as a type of mixing necessary inputs in proper way. Domestic business, together with Russian Government and, probably, in cooperation with some international players, needs to solve the problem of deepening the production cycle, look for stimulus for development of the entire production chain in the long-term perspective, including development of fundamental science in chemical crop protection industry. Learning and adapting foreign experience can be the first step in the process of structural change of the crop protection industry. Simultaneously, it is critical to maintain openness and desire to use best practices at pesticide market, without which the competitiveness of Russian agricultural production will be constrained and development of the entire industry will have a pace inferior to other countries.
Esenin and Ryazan Periodicals of the Early 1910s
Authors: Solobay Nina M.
Published: January 2024

The article describes in detail the Ryazan periodicals (“Ryazanskiye Gubernskiye Vedomosti,” “Ryazanskiye Yeparkhial’nyye Vedomosti,” “Ryazanskaya zhizn,” “Ryazanskiy vestnik”). These newspapers were supposedly included in the reading circle of S.A. Esenin during his studies at the Spas-Klepiki second-grade teacher’s school and in subsequent years. A frontal review of these publications allowed the auther to establish that they published both literary texts (prose and poetry) and reviews of current literature. From these publications Esenin could learn about the work of the Surikov literary and musical circle and get acquainted with the work of its members. Since the mid-1910s Esenin’s had also appeared in the Ryazan periodicals — as the author of the capital’s publications. The most number of publications about the poet was caused by his tragic death and subsequent projects to memorialize Esenin’s memorable places.
The Image of China in the Life and Work of Sergey Esenin
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Samodelova Elena A.
Published: January 2024

Knowledge about China entered the Esenin’s life from school textbooks, stories of friends who visited this state. The image of China and references to it (about the Great Wall of China) and its inhabitants are found in the poems “Pugachev” and “The Country of Scoundrels,” in the autobiography and the statement of the poet. The author of the article puts forward a hypothesis about the Mountainous Country, whose high mountains on the borderlands of Russia and China were considered sacred and leading to a paradise country, and they could become the prototype of the mountains in Esenin’s “Inonia.” The article deals with main “Chinese metaphors” in Esenin’s writings, except for the principal image — Litza-Khun (Chinese) — the “Soviet detective,” to whom a separate work will be devoted.
Combining Words into a “Sound One-Punch”: from the Experience of Preparation the Dictionary of the Rhymes by S.A. Esenin
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Zimenkov Alexey P.
Published: January 2024

The article is devoted to the analysis of the problems that arose during the preparation of “The Dictionary of the Rhymes by S.A. Esenin.” The author describes the situations when the graphics of the poetic text deprived the Esenin’s verse and stanza of visual certainty, and the approximate rhyme could not serve as a sound marker of the end of the verse. The author presents recommendations that allow the compiler to find the rhyming consonances of Esenin in contexts with high uncertainty. The problem of the left borders of the Esenin rhyme is considered, it is established that, rhyming, the poet actively uses prepositions and conjunctions, many of which were not previously included in rhyming consonances. It is shown how the inaccuracy of Esenin’s rhymes is compensated by the rhythmic identity of rhyming words, as well as vowels and consonants in words located outside the rhyme pairs.

Published: January 2024

The article deals with the translations of Sergey Esenin’s works into Georgian. Georgian poets-translators have repeatedly turned to the work of the poet since the 20s of the 20th century. Esenin’s work has always been of great interest not only to Georgian poets-translators but also to Georgian readers. Translation activity began in Georgia in 1924 by Konstantin Chichinadze from the translation of the poem “Comrade.” It began to be actively continued by Mikheil Pataridze. In 1926 a collection of Esenin’s poems was published as a separate book, which combined 15 poems by the poet, in 1927 — a separate edition of the poem “Anna Snegina” (in translation by Grigola Tsetskhladze). By the end of 1956, the translation of the poem was published in two periodicals at once (“Mnatobi,” “Talga”). Both versions were made by the Georgian poet and translator Giorgi Salukvadze. Fortunately, another edition of the poem “Anna Snegina” was found in the collection of poems and poems, dated 1969 (Batumi “Sabchota Adjara”). All works are translated by Giorgi Salukvadze. In 1981 translations of Esenin’s poems were published in the literary and social magazine “Chorokhi.” In 1984 a collection of the poet’s poems was published in Batumi (Batumi “Sabchota Adjara”). The translator of both editions is Salukvadze.
A French Detective Novel about S.A. Esenin

Published: January 2024

The article examines Jean de Boishue’s novel “La Vie interrompue de Sergueï Alexandrovitch Essenine” (Paris, Bartillat Publ., 2021. 250 p.) Jean de Boishue (born in 1943) is a grandson of the founder of the Russian House in Saint-Geneviève-des-Bois, Princess Vera Meshcherskaya, a former statesman (adviser to the French Prime Minister Francois Fillon, deputy, member of the State Council). Boishue relies mainly on Eduard Khlystalov, Stanislav and Sergey Kunyaev (but keeps silent about it) and introduces a fictitious retired KGB colonel of the perestroika epoch to investigate the circumstances of S.A. Esenin’s death. The novel is divided into 33 chapters, in which truth and fiction are mixed. The author of any novel is free to interpret events at his own discretion, but incomprehensibly Jean de Boishue made many factual inaccuracies, absurdities and contradictions that undermine the main thesis of this otherwise wellwritten conspiracy novel.

Published: January 2024

The article includes the examples that refl ect the life and creative activity of the prominent representatives of Russian literature during the Second World War. Among them are I.D. Surguchyov, Don-Aminado (A.P. Shpolyansky), general P.N. Krasnov, G.V. Ivanov, N.A. Taffy, M.A. Osorgin, D.S. Merezhkovsky, Z.N. Gippius, I.A. Bunin, I.S. Shmelyov, B.K. Zaitsev and others. The article notes that the Second World War exposed many contradictions hidden in peacetime. Some of the Émigré writers collaborated with the Nazis and took part in “Parizhsky Vestnik” and in “Novoe Slovo” (Berlin) newspapers published with the support of the Nazis. They considered Germany’s war against the USSR as a historical campaign against Bolshevism and the only opportunity in recent conditions to destroy it. The author of the article analyzes V.I. Goryansky’s satirical poems on the pages of the “Parizhsky Vestnik” for the fi rst time: namely “The Cheerful Churchill,” “Spring Tornado” and other publications. The article demonstrates the participation of the representatives of the Russian Émigré literature in fi ght against fascism and in the Résistance Movement. These examples show that the majority of the Russian Émigré writers retained patriotic feelings towards the abandoned homeland and did not support Hitler’s aggressive plans.

This study aims to examine the relationship between parent resilience, couple burnout, and misogyny of fathers with disabled children, while also investigating the mediating effect of parent resilience on the relationship between misogyny and couple burnout. This study included a sample of 120 fathers whose children were attending a special education and rehabilitation center. Couple Burnout Scale Short Form, Misogyny Scale, Family Resilience Scale, and Personal Information Form were used as instruments in the study. The findings revealed a significant relationship between couple burnout and levels of misogyny, as well as a negative relationship between couple burnout and perception of parent resilience. Additionally, a negative relationship was observed between the level of misogyny and parent resilience. Importantly, parent resilience was found to mediate the relationship between level of misogyny and couple burnout, explaining 24.5% of the total variance. Based on these findings, it is recommended to prioritize psychological interventions that strengthen resilience of fathers with disabled children.

Predicting M-Payment Adoption Intention in Indonesia: Integrating Technology Acceptance Model and Psychological Factors
Authors: Susiloadi Priyanto , Renanita Theda , Julaibib
Published: January 2024

The government is currently promoting the growth of m-payment usage in Indonesia. Therefore, research is needed to identify the factors influencing the adoption intention of m-payment. One theory frequently employed to elucidate the usage intention of m-payment is the Technology Acceptance Model (TAM). According to this theory, intention arises from perceived usefulness and perceived ease of use. This study integrates TAM with psychological variables, namely, trust and subjective norms. This research aims to examine the factors influencing the adoption intention of m-payment. Before conducting the model test, this research begins with adapting and validating all measurement tools in the Indonesian language. Participants in this study are individuals aged 17 and above who own smartphones. The entire data collection is done online. The research instrument is validated with confirmatory factor analysis (CFA) on perceived usefulness, perceived ease of use, trust, subjective norm, and the adoption intention of m-payment (N=209). The model test is conducted through path analysis (N=210). The validation process confirms the theoretical model of the five instruments in the Indonesian version. The CFA results indicate that all five research instruments meet the cut-off criteria for fit indices RMSEA, CFI, TLI, and SRMR. The path analysis results reveal that perceived usefulness, perceived ease of use, and subjective norm influence the adoption intention of m-payment. In contrast, trust does not affect the adoption intention of m-payment. This research contributes both theoretically and practically, particularly regarding the factors influencing m-payment adoption.

The need for bone implants is constantly increasing every year as the population of older people, accidents, and bone diseases increase. Various solutions, such as autograft, allograft, and artificial endoprosthesis, have been developed by researchers. Ceramic or bio-ceramic materials become very attractive as bone implants due to their high biocompatibility. One of the most commonly used bio-ceramics today is hydroxyapatite (HAp). Hydroxyapatite is one of the biomaterials that are widely used as biomedical materials, such as bone fillers, bioactive implant coatings, bone tissue repair systems and drug distribution. Kabupaten Gresik is famous for its fisheries, including the scallop mussel shells. The scallop mussel shells (Ruditapes philippinarum) is a species of shells that is widely cultivated in the Kabupaten Gresik. Using scallop mussel shell wastes as hydroxyapatite raw material can reduce shell waste volumes and production costs. Several methods for producing hydroxyapatites include hydrothermal, sol-gel, mechanochemical, wet chemical and microwave methods. Hydroxyapatite synthesis with the microwave method has the advantages of efficient heating, environmentally friendly and economical. This study aims to characterize and synthesize hydroxyapatite using scallop mussel shell waste prepared using microwave-assisted precipitation methods in the Gresik Regency. The research was carried out to convert the scallop mussel shells resulting from calcination with the crystal phase Ca(OH)2 into hydroxyapatite using the microwave method. The synthesis process with the method of microwaves at the power of 450 watts for 2.5 minutes. From the synthesis results, hydroxyapatite was then characterized by XRD and SEM tests. The XRD tests carried out formed 99.1% crystallinity of hydroxyapatite.

St. Michael’s Mount: From Christian Folklore to New Age Mythologies
Authors: Hayward Philip
Published: January 2024

St. Michael’s Mount, a small, tidal island in Mount’s Bay, close to the south-western tip of the English county of Cornwall, is both a highly picturesque tourism attraction and a place that has become associated with various aspects of Christianity, Christian folklore and, more latterly, New Age mysticism. While the island was a centre for Christian pilgrimage in the 12th-14th centuries, at a time when it was closely associated with St. Michael the Archangel and the Benedictine order devoted to him, several other religious and spiritual associations are more recent. One notable folkloric tale, which arose long after the Order had departed, concerned the manifestation of St. Michael on the island. This was also influential in a more modern folkloric connection, that of the island being located at the intersection of two “leys” (lines of spiritual power): one English one, running north-east from St. Michael’s Mount to Bury St. Edmunds, and one international one, running south-east from Ireland to Bethlehem. These aspects are discussed with regard to the island being a nexus of various mythical and spiritual aspects within historical, popular cultural, New Age and tourism contexts. The article identifies how associations can accrete around locales and suggest them as spiritually infused in a broad and somewhat “fuzzy” manner that facilitates multiple affective and representational engagements with them.

Published: January 2024

The implementation of the sustainable development objectives, requires additional knowledge about underwater landscapes of inland reservoirs. In this article, we assumed that (1) underwater landscapes of lakes are shaped mainly by the type of substrate and the assemblages of flora and fauna inhabiting a given reservoir; (2) vegetation is one of the most important elements of underwater landscapes, which dynamically reacts to environmental changes. This article presents the results of a study on the underwater landscapes of Lake Wielki Staw in the Karkonosze Mountains. Thirteen types of underwater landscapes were distinguished in the lake based on underwater inventory and spatial analysis using ArcGIS 10.7 software. The level of changes that occurred in the underwater landscape studied was determined using the underwater landscape structure maps for 2005, 2011, 2017, and 2021. In addition, the landscape change index ( LCI) for Lake Wielki Staw was determined for 2005–2011, 2011–2017, and 2017–2021. The results obtained indicate that underwater landscapes in lakes, similarly to terrestrial landscapes, are dynamic and subject to changes. In the case of Lake Wielki Staw, the changes in the range of Isoëtes lacustris communities in individual parts of the lake limited the differences in the area of all types of underwater landscapes distinguished. This allows us to use underwater vegetation inhabiting a given reservoir as an indicator of changes in underwater landscapes. Keywords:

The determination of the batoh area as the new city center increased land user activities in the area so that there was also an increase in activities on the area's main road, namely Jalan Mr. Teuku Moh. Hassan. To find out the relationship between the development of land use in the area and the loading on the main road, it is necessary to know the factors that influence the increase in the burden on the road. To find out, the traffic volume and road capacity were calculated and modeling the trip generation and attraction caused by land users by dividing the layers for each area. Layer 1 is a commercial land use, while layers 2 and 3 are residential land use. For variables in commertial area, 3 variables were be calculated, while for residential areas 7 variables are thought to affect the burden. From the results, data processing was carried out and the capacity of the road was 2696,1 smp/hour. For the generation and pull data, multiple linear regression analysis was carried out using the backward method so that the modeling for layer 1 Y = 0.590 + 1,341 X3, for layer 2 Y = 0.220 +0.748 X1 + 0.828 X2 + 0.626 X3, and for layer 3 Y = -0.260 + 0.834 X1 + 0.720 X2 + 0.453 X3 + 0.225 X7.

Aceh Selatan merupakan daerah di Provinsi Aceh yang rawan terjadinya banjir. Salah satu upaya pemerintah yaitu pembangunan Bendungan Krueng Kluet, Kabupaten Aceh Selatan. Tipe kolam olak di bendungan Krueng Kluet adalah USBR III. Perubahan aliran dari superkritis ke subkritis menyebabkan terjadinya loncatan hidrolik. Loncatan hidrolik menyebabkan adanya gerusan di hilir kolam olakan. Tujuan penelitian ini adalah mengetahui karakteristik aliran serta pengaruhnya terhadap pola dan kedalaman gerusan. Metode penelitian ini berupa model fisik tak distorsi dengan skala 1:60 yang dibangun di Laboraturium Hidraulika Model Teknik Sungai dan Pantai Jurusan Teknik Sipil Fakultas Teknik Universitas Syiah Kuala. Variasi debit yang dialirkan yaitu Q2th, Q5th, Q10th, Q25th, Q50th, Q100th dan Q1000th. Parameter yang diukur adalah tinggi muka air, kecepatan aliran, loncatan hidrolik, dan kedalaman gerusan. Hasil yang diperoleh yaitu pola dan kedalaman gerusan sangat dipengaruhi oleh karakteristik aliran dimana semakin besar karakteristik aliran maka gerusan yang terjadi juga akan semakin besar. Pola gerusan pada semua variasi debit cenderung konsisten membentuk pola yang sama, yaitu gerusan terjadi pada bagian tengah sementara pada bagian sisi kiri dan kanan hilir kolam olakan terjadi penumpukan sedimen. Kedalaman gerusan terkecil terjadi pada debit Q2th sebesar 5,76 m dan kedalaman gerusan terbesar terjadi pada debit Q1000th sebesar 14,82 m.
