Authors: Andrade Pinheiro Viviane , Mara Mendonça Edna , Cristina Costa Elizabete , Carlos de Oliveira Calisto Gleibson , Reis Rodrigues José de Arimatéia , Andrade Pinheiro de Lima Bruna
Published: December 2021

OBJETIVO: o presente artigo traz reflexões a respeito das políticas sobre drogas no Brasil e suas relações contraditórias no que tange à estratégia de redução de danos, especificamente na área da saúde mental, álcool e outras drogas. MÉTODO: Os métodos utilizados foram pesquisa bibliográfica e documental, privilegiando publicações de 1990 a 2021. O período da coleta de dados se deu nos anos de 2019, 2020 e 2021, onde aconteceram as principais alterações nas leis. RESULTADO: O debate se dá em torno de como o viés proibicionista habitou a mesma política durante todo o tempoem que a redução de danos foi considerada uma estratégia de cuidado às pessoas que usam drogas. Entretanto, a política de drogas brasileira, ganhou novos contornos a partir do ano de 2017. CONCLUSÃO: Concluiu-se que o predomínio do proibicionismo e seu retorno à legislação dos últimos anos, legitimou oficialmente a criminalização do uso de substâncias psicoativas e consequentes retrocessos em relação ao cuidado das pessoas que usam drogas.

Accurate Segmentation for Low Resolution Satellite images by Discriminative Generative Adversarial Network for Identifying Agriculture Fields
Authors: Joseph S. Iwin Thanakumar
Published: December 2021

Agricultural field identification is still a difficult issue because of the poor resolution of satellite imagery. Monitoring remote harvest and determining the condition of farmlands rely on the digital approach agricultural applications. Therefore, high-resolution photographs have obtained much more attention since they are more efficient in detecting land cover components. In contrast, because of low-resolution repositories of past satellite images used for time series analysis, wavelet decomposition filter-based analysis, free availability, and economic concerns, low-resolution images are still essential. Using low-resolution Synthetic Aperture Radar (SAR) satellite photos, this study proposes a GAN strategy for locating agricultural regions and determining the crop's cultivation state, linked to the initial or harvesting time. An object detector is used in the preprocessing step of training, followed by a transformation technique for extracting feature information and then the GAN strategy for classifying the crop segmented picture. After testing, the suggested algorithm is applied to the database's SAR images, which are further processed and categorized based on the training results. Using this information, the density between the crops is calculated. After zooming in on SAR photos, the crop condition may be categorized based on crop density and crop distance. The Euclidean distance formula is used to calculate the distance. Finally, the findings are compared to other existing approaches to determine the proposed technique's performance using reliable measures.

Authors: Opiela S. Maria Loyola
Published: December 2021

Edmund Bojanowski rozwijał swą myśl pedagogiczną w połowie XIX wieku i dokonywał jej praktycznej aplikacji zachowując zasady wynikające z niezmiennej natury człowieka, praw jego rozwoju i wartości najwyższych, dostosowując metody, formy i środki wychowania do specyfiki społeczno-kulturowej danego środowiska. Szczegółowe wskazania zawarł w swej bogatej spuściźnie i dzięki temu są wciąż realizowane w tradycji pracy wychowawczej Zgromadzenia Sióstr Służebniczek, podejmujących działalność edukacyjną w różnych krajach na świecie. Dokonując twórczej interpretacji myśli pedagogicznej Bojanowskiego, Służebniczki wciąż odczytują ją na nowo w zmieniających się warunkach społeczno-kulturowych i wobec aktualnych wyzwań edukacyjnych. Jej ponadczasowy i uniwersalny wymiar stanowi podstawę do jej aplikacji w perspektywie międzynarodowej.

MUSIC AND COMMUNICATION PROCESSES IN SOCIETY: MANAGEMENT THEORY
Authors:   Russian State Specialized Academy of Arts, Moscow, Russian Federation, Yakoupov A. N.
Published: December 2021

Based on historical and theoretical analysis of the development of social functioning of musical communication, as well as some problems of its management, the author attempts to theoretically justify the ways and means of optimizing music and communication processes that contribute to enhance the social and cultural role of musical art. The article describes fundamental concepts, which should be taken as the basis for the organization of musical life in modern society. The author puts forward such a conceptual theoretical statement as the principle of multi-factor audience differentiation. Consequently, the paper considers important facets of the theory of musical communication management in society, namely the target programming, scientific forecasting and long-term planning. The ways and methods of implementing these principles aimed at the achievement of a certain level of control over the music communication processes in society are also considered. Special attention is paid to the analysis of the impact of current social and economic changes in Russia on the formation of marketing and management in the social life of musical art.

Authors:   Saint Petersburg State University, Saint Petersburg, Russian Federation, Tolstova A. A.
Published: December 2021

The study aims to describe the structural relationships between the elements of the design process through understanding and describing the nature of mutual support and constraint. The research hypothesis assumes that achieving this goal will enable to explore the possibilities of influencing the process in order to regulate it. The study uses general scientific cognitive tools such as content analysis, synthesis, and the "wu-xing pentagram" symbolic method, which is a tool of categorical-systemic methodology. As a result, the mechanism of components communication: author — object — subject as the main in the design process is identified. Moreover, a model describing the structural relations between these components is developed and interpreted. The model allows to propose a mechanism for indirect control of the design process as a system activity. Finally, theoretical and practical results of further work are considered.
THE CULT OF THE MOTHER OF GOD IN RUSSIA AND THE TRANSFORMATION OF ORTHODOX ICONOGRAPHY

Published: December 2021

Byzantine iconography is the primary basis for the formation and development of the Russian tradition of depicting the Akathist to the Holy Virgin. The Akathistic iconography, becoming the visual culmination of Mariological Christianity, embraced the entire sum of symbolic meanings of the image of the Virgin and, due to the special veneration of Our Lady in Russia, received a special meaning in Russian culture. Despite all the perfection of the iconographic types developed in Byzantium, the Theotokos image in iconography could not remain unchanged. The iconography of the Virgin is quite comparable to a similar phenomenon in church poetry, where in the Akathistos, so widespread in Russia, a different combination of epithets and comparisons creates each time a unique verbal image of the Virgin. The Akathist to Our Lady became widespread in Russia in the first half of the XIVth — early XVth centuries. From the functional aspect of "motherhood" a transformation of the perspective "spiritual motherhood in relation to believers" is drawn, since the icons show Our Lady in the role of "the real mother of every believer", "the mother of everything earthly on earth." The transformation of the functional aspect "place in the hierarchy system" determines the angle "leader of the heavenly army" — the Mother of God is shown by the intercessor of the Moscow Kingdom.
SERGEY PROKOFIEV AND SERGEY SLONIMSKY: A DOUBLE PORTRAIT IN THE INTERIOR OF THEATER, CINEMA AND RADIO
Authors:   Moscow State Tchaikovsky Conservatory, Moscow, Russian Federation, Kailin Zhang
Published: December 2021

This article demonstrates the general principles in the work of S. S. Prokofiev and S. M. Slonimsky, artists who are brightly individual and bold in their creative search. This thesis is confirmed by the two composers' memoirs: Prokofiev's Autobiography and Slonimsky's "Burlesques, Elegies, Dithyrambs in Despicable Prose". The author touches upon the theme "the Composer and the Drama Theater", which reveals the approach of the director (G. A. Tovstonogov) and the composer (S. M. Slonimsky) to the musical design of the performance based on the novel "Quiet Flows the Don" by M. A. Sholokhov. The paper provides excerpts from the book of the famous actor, screenwriter and director A. V. Batalov, as well as his views on radio dramaturgy as the director of a radio play about the childhood of Sergey Prokofiev. It is emphasized that A. V. Batalov made an accent on the leading role of the composer's works in compositional dramaturgy of the radio performance.
AESTHETICS OF GLITCH ART: ORIGINS AND MEANINGS
Authors:   Moscow Military Music School named after Lieutenant-General V. M. Khalilov of the Ministry of Defense of the Russian Federation, Moscow, Russian Federation, Nagornaya L. N.
Published: December 2021

The relevance of the article is associated with the rapid development of various forms of digital art, due to the increasing role of information technologies, which have caused fundamental transformation processes in the modern cultural environment. The article is devoted to the origin and value-semantic foundations of such a direction of modern digital art as glitch art. The origins of this direction, which lies in the aesthetics of Futurism, experiments in concrete music, as well as in the technique of deconstruction and recombination of parts of the original image in Cubism, are considered. Examples of glitch art are given — "Tali Hinkus" by Paul Hertz, "Glitch Diva" by Elena Romenkova, "White" (from the "Utopia" series) by Viktor Makurin, parallels with cinema works ("The Matrix" directed by Wachowski) are drawn. An important property of digital art is its ability to fill the global information space with new meanings and values: it is both a protest against total technocracy and digitalization, and a fixed gap in collective techno-hypnosis, and a display of the processes of the human subconscious. The study of this phenomenon allows to take a critical look at the interaction of the physical and digital world within modern culture, to identify the prospects for this interaction.
ON THE EXISTENCE OF THE OLD RUSSIAN DOMRA
Authors:   A. A. Bakhrushin State Central Theater Museum, Moscow, Russian Federation, Makhan V. V.
Published: December 2021

The article examines written, linguistic and pictorial sources about the Old Russian domra of the XVIth — XVIIth centuries, on the basis of which the author confirms, questions and puts forward new hypotheses about its existence, construction and performance character. A large number of sources — explanations in alphabet books, mentions in scribal books of professions, surnames and geographical names derived from domra testifies to the widespread use of domra in Russia during this period. Miniatures showing the domra in different shapes of the body, length of the neck, and number of strings are analyzed. Agreeing with the conclusion about the existence of the Old Russian domra in two main varieties, the author notes that the domra could be an independent type of lute instrument, which absorbed the features of both tanbure-like and lute-like instruments (in A. S. Famintsyn's classification). There is a new hypothesis that in Old Russian literature domras could be called "pregudnitsy" as a general name for stringed instruments, and domra players could be called "pregudniks". New data are introduced into scientific circulation: based on a document of 1719, discovered by the author, the chronological framework for the Old Russian domra is expanded to the first quarter of the XVIIIth century, and the fact of the simultaneous existence of domra and balalaika is established. Assumptions are made about the nature of playing and techniques of performing on domra. The version of the existence of the domra's tessitura varieties is questioned, due to insufficient documentary evidence. It is concluded that all the considered evidence was a sufficient ground for the reconstruction of domra in 1896.

Published: December 2021

The article presents the results of a study of the features of coverage of events involving disabled people in modern Russian media. The data obtained are considered in four perspectives: the reflection of socio-demographic characteristics of the disabled in the media, the main topics covered by publications with the participation of disabled people, the activity of disabled people described by the media, the general emotional coloring of news articles about people with disabilities. The article is based on the results of content analysis of news articles published in the period from December 2020 to August 2021 in RBC, RIA Novosti, Rossiyskaya Gazeta, TASS, Izvestia. The analysis showed that the image of a disabled person broadcast in the media is poorly differentiated with respect to socio-demographic parameters and health characteristics, leaving out of consideration the diversity of material living conditions and the social situation of people with disabilities. Basic needs are prevalent in the description of disabled people, while creative and spiritual ones are leveled. The media articles are dominated by paternalistic attitudes in characterizing the disabled: they need protection and assistance provided by the executive branch and law enforcement agencies. Despite a sufficiently high social activity, a disabled person turns out to be an object of action that has no identity.
EVGENY GOLUBEV AND NATIONAL MUSICAL CULTURES
Authors:   Moscow State Tchaikovsky Conservatory, Moscow, Russian Federation, Sanko A. K.
Published: December 2021

The article is devoted to the pedagogical activity of Evgeny Kirillovich Golubev (1910– 1988) — composer, professor of the Moscow State Conservatory, whose 110th birthday was celebrated in 2020. The relevance of the study lies in the fact that for the first time Golubev's contribution to the education of not only Russian composers, but also representatives of different national cultures — Hrant Grigoryan, Kapan Musin, Todor Popov, Andrey Eshpai and others is considered. The questions of the master's compositional pedagogy, which were little studied until now, are touched. The object of the research is Golubev's diary "Alogisms", as well as the memories of his students. The author highlights activities of Golubev's students who connected their creativity with other national cultures. Among them were Valentin Konchakov (1933–1993) who worked in Karelia and contributed greatly to the development of folk art in this republic, and the composer Aida Isakova (1940–2012) who participated in the formation of Kazakh musical culture in Alma-Ata and wrote essays on national themes.

Cet article présente l’évolution de l’ARN du SARS-CoV-2 dans les filières de traitement des eaux
et des boues du site Seine Valenton – Syndicat interdépartemental pour l’assainissement de l’agglomération
parisienne (Siaap) - Sival. Cet article vise à contribuer à l’amélioration de la connaissance sur le devenir,
dans les usines de traitement des eaux usées, du matériel génétique du virus responsable de la pandémie
de Covid-19. À partir d’échantillons d’eaux et de boues prélevés à différentes étapes de traitement de la
station d’épuration de Valenton, les gènes N1 et N2 du virus ont été mesurés par RT-qPCR après extraction
de l’ARN et les bactériophages ARN F-spécifiques ont été dénombrés. Les résultats confirment qu’il y a une
relation entre la quantité de SARS-CoV-2 dans les eaux usées et la dynamique de l’épidémie. Les résultats
indiquent également que la filière de traitement d’une usine d’épuration assurant un traitement complet de
l’azote permet un abattement d’environ 2,5 à 3 log pour les gènes N1 et N2 du SARS-CoV-2. Le matériel
génétique est logiquement retrouvé dans les boues fraîches, avec des niveaux d’ARN qui suivent les
dynamiques observées dans les eaux brutes. Les étapes de traitement des boues montrent également une
efficacité pour réduire les niveaux de concentration de l’ARN du SARS-CoV-2, notamment au niveau du
séchage thermique. En conclusion, cette étude montre que les niveaux de concentration du matériel
génétique du SARS-CoV-2 sont inférieurs aux limites de quantification au rejet de la station d’épuration et
qu’ils sont soit faibles, soit inférieurs aux limites de quantification pour les boues séchées.
Research note: Lies and presidential debates: How political misinformation spread across media streams during the 2020 election
Authors: Haber Jaren , Singh Lisa , Budak Ceren , Pasek Josh , Balan Meena , Callahan Ryan , Churchill Rob , Herren Brandon , Kawintiranon Kornraphop
Published: December 2021

When U.S. presidential candidates misrepresent the facts, their claims get discussed across media streams, creating a lasting public impression. We show this through a public performance: the 2020 presidential debates. For every five newspaper articles related to the presidential candidates, President Donald J. Trump and Joseph R. Biden Jr., there was one mention of a misinformation-related topic advanced during the debates. Personal attacks on Biden and election integrity were the most prevalent topics across social media, newspapers, and TV. These two topics also surfaced regularly in voters’ recollections of the candidates, suggesting their impression lasted through the presidential election.

Periodic Solutions of One-Dimensional Cellular Automata with Uniformly Chosen Random Rules
Authors: Gravner Janko , Liu Xiaochen
Published: December 2021

We study cellular automata whose rules are selected uniformly at random. Our setting are two-neighbor one-dimensional rules with a large number $n$ of states. The main quantity we analyze is the asymptotic distribution, as $n \to \infty$, of the number of different periodic solutions with given spatial and temporal periods. The main tool we use is the Chen-Stein method for Poisson approximation, which establishes that the number of periodic solutions, with their spatial and temporal periods confined to a finite range, converges to a Poisson random variable with an explicitly given parameter. The limiting probability distribution of the smallest temporal period for a given spatial period is deduced as a corollary and relevant empirical simulations are presented.
Integral Mixed Cayley Graphs over Abelian Groups
Authors: Kadyan Monu , Bhattacharjya Bikash
Published: December 2021

A mixed graph is said to be integral if all the eigenvalues of its Hermitian adjacency matrix are integer. Let $\Gamma$ be an abelian group. The mixed Cayley graph $Cay(\Gamma,S)$ is a mixed graph on the vertex set $\Gamma$ and edge set $\left\{ (a,b): b-a\in S \right\}$, where $0\not\in S$. We characterize integral mixed Cayley graph $Cay(\Gamma,S)$ over an abelian group $\Gamma$ in terms of its connection set $S$.
Microfinance Services and the Clients’ Socioeconomic Wellbeing During the Covid-19 Pandemic in Uganda
Authors: Kizza James
Published: December 2021

Microfinance is reported to be an effective tool of empowerment for vulnerable and marginalised groups, especially women. This study set out to investigate the relationship between microfinance services and the clients’ socioeconomic wellbeing during the Covid-19 pandemic in Uganda. The study involved 73 employees of microfinance institutions that deal directly with the clients. The study findings revealed that while no significant relationship exists between microfinance services and clients’ socioeconomic wellbeing, there is a significant moderate positive relationship between microfinance client protection policies and the clients’ socioeconomic wellbeing. The regression model revealed that a unit increase in client protection policies increases the socioeconomic wellbeing of microfinance services beneficiaries by 72%. It is recommended that microfinance institutions integrate client protection policies in their activities in line with their known social mission

Authors: Kalogiannidis Stavros , Kontsas Stamatis , Chatzitheodoridis Fotios
Published: December 2021

The aim of the paper was to assess the level to which managerial styles in an organization affect employee performance among selected banks in Greece. The study focused on three major managerial styles which include; democratic, autocratic and participatory styles of management. The study utilized a descriptive research design and an online survey was used to collect relevant data from different employees attached to selected banks in Greece (National Bank of Greece, Piraeus Bank, Citibank Greece, and HSBC Greece). The survey targeted 220 employees though only a response rate of 87.3% was obtained based on 200 employees that answered questions contained in the survey questionnaire. The different study findings showed that all the managerial styles are positively associated with employee performance except autocratic managerial style which had a positive but insignificant relationship with employee performance. The study concluded that it is very important for managers to continuously apply different innovative managerial styles in executing their duties since this has a great impact on the general performance of employees.

Titanomagnetites are a complex raw material with a high content of valuable components: iron (35–65 %), vanadium (0.5–1.5 %) and titanium (2–14 %). Today, titanium–magnetite concentrates are processed in two ways: blast furnace (Russia, China) and using electric smelting (South Africa). The blast–furnace method is applicable only for low–titanium titanomagnetites. In the case of using titanomagnetite concentrates with a titanium dioxide content of more than 4 %, the method of electric smelting with preliminary reduction is applicable. Both technologies aim to recover the two components iron and vanadium, while titanium is not recovered. In this regard, the development of a complex technology for processing titanomagnetite concentrate to obtain iron in granular form, vanadium pentoxide and titanium is urgent.

The process of sorption of phosphate ion by silicon dioxide obtained by acid decomposition of nepheline is studied. The experimental data were processed using the Freundlich and Langmuir sorption equations, which showed that the sorption process is fairly accurately described by both equations, while the use of the Langmuir monomolecular adsorption equation is preferable in the calculations. The capacity of the adsorption monolayer of the synthesized sample relative to the РО43–-ion and the adsorption equilibrium constant are calculated. Based on the obtained data, various options for sorption treatment of municipal wastewater from РО43--ion to normalized MPC values were evaluated.
