Precedent Anthroponyms of Soviet Origin in English Polycode Advertising Text
Authors: Dziuba E. V. , Rogozinnikova Yu. V.
Published: May 2021

The article analyzes precedent anthroponyms of the Soviet origin in multimodal texts of American and British advertising. The study aims at analyzing precedent anthroponyms of the Soviet origin in English multimodal texts from the linguoaxiological and linguopragmatic points of view and from the standpoint of textual organization. The following research methods have been used: description and synthesis, linguistic methods of structural-semantic, contextual and cognitive-discourse analysis. The paper examines the precedent names of the Soviet origin (for instance, Lenin, Stalin, Brezhnev, Gorbachev, Yeltsin, and Kalashnikov). It also establishes their uses in commercial texts and highlights the linguistic means of satirical effect creation as the main pragmatic goal of English commercial and social advertising. The name of a political leader acquires different connotations and in most cases it is “demoted” due to the transfer of the name from the political context to the everyday one: gastronomic, material, kitsch-cultural, glamorous-erotic, etc. Names of the Soviet politicians are found in advertisements of cigarettes, pizza, alcoholic and nonalcoholic drinks, bags and other household items, including absorbent wipes. The article concludes that the image of the Soviet past in multimodal advertising texts in English acquires negative connotations. Besides, the analyzed texts emphasize that the communist ideology belongs to the system of anti-values.
Particular Semantic and Syntactic Properties of Polyfunctional Lexeme LI
Authors: Zavialov V. N. , Ma Xu
Published: May 2021

The object of the article is a non-descriptive lexeme. Its use is investigated in various semantic-syntactic and communicativepragmatic contexts. The relevance of the work is due to the need for amore holistic description of a number of primitive linguistic units (a, and, either, or, etc.), the categorical properties of which are not fully and systematically identified within the framework of traditional methods of analysis. The novelty of the work lies in the consideration of all uses within the framework of the functioning of the lexeme-particular of the same name. This approach is due to the principles of nonparadigmatic linguistics — a modern trend in the study of primitive lexemes. The theoretical significance of the work lies in the introduction into scientific circulation of the principles of the analysis of a particular li based on its ancient categorical properties associated with the semantics of conjecture. It has been established that in all the considered contexts we are dealing with the same particular lexeme, which retains its original categorical properties in them. They are manifested in the questioningness of li (direct or indirect), as well as in various hypothetical meanings that are realized in sentences-statements at a deep syntactic level. Asimilar description technique is applicable to the analysis of the properties of other particular units of the Russian language.
Titles of Memoir and Autobiographical Texts about First World War: “War Captivity” Frame
Authors: Banman P. P.
Published: May 2021

The article is devoted to the analysis of the “Kriegsgefangenschaft” / “War Captivity” frame, the identification of its slots and their filling based on the headings of German-language memoir and autobiographical texts written by prisoners of war of the First World War. It is noted that these materials did not become the subject of a wide study of Russian-speaking researchers. The author draws attention to the fact that headings, being a strong position of the text, are aimed at attracting the attention of a potential recipient. It has been established that in the course of the author’s semantization, the concept of “captivity” is subject to rethinking: places of stay in captivity (Russia, Siberia) are described as disastrous: the camps become a prison for prisoners of war who, despite the existence of conventions protecting their rights, turn into convicts. It is shown that the slot “time” implies either an exact indication of the historical period (the years of the First World War), or the duration of being in captivity; in isolated cases, we are talking about the age and period of a person’s life. It has been established that the “agent” slot is filled with anthroponyms, indicating nationality, position, rank, profession. The author comes to the conclusion that the identified slots get their further implementation at the text level.
Modern Professional Language of Robotics (Terminological Family “Robot”)
Authors: Zaitseva A. S.
Published: May 2021

The article is devoted to the study of the terminological family with the base term “robot”. The issues concerning the structure of the terminological family, its basic lexical units, the most productive models of term formation and most frequent grammatical forms of terms are considered. Particular emphasis is placed on the specifics of the terminological family. The characteristic features of terminological elements used in the formation of new terms are defined. It is emphasised that the emergence of terminological combinations is a common way of forming new special words. In the course of study, it was found that the terminological family with the base term “robot” belongs to the class of highly deployed families. A five-stage model of the terminological family is presented. About 200 derived terms have been analysed at the five stages of term formation relating to the present state of language development. The scientific hypothesis that the emergence of terms-specifiers of the original concept is the way of forming a special professional terminological family has been proved. The material for research includes the “English-Russian Explanatory Dictionary” by E. M. Proydakov and L. A. Teplitskiy (Moscow, 2019), monographs, scientific publications on robotics in peer-reviewed journals in 2010—2021.

Authors: Bacoş Ioan-Bogdan , Gabor Manuela Rozalia
Published: May 2021

Daily exposure to ambient air pollutants harms human health and the environment. Even though in recent years air quality is a taboo subject discussed and researched by many interested areas, pollution indices often exceed the pollution norms imposed by the authorities in major European cities. In response to these environmental problems, the European Union has created a body of legislation on pollution indicators. On the other hand, World Economic Forum promote the travel tourism competitiveness index (including the pillar of environmental sustainability). The purpose of this paper is to present and analyse the indicators from the environmental sustainability pillar within TTCI (Travel and tourism competitiveness index) and the air pollution indicators, respectively the air quality standards and the pollution norms. As a short result, România exceeds at some indicators and has a lot to improve at the others (Enforcement of environmental regulations).

Discursive Representations of Education for Sustainable Development in Policy Documents by English Medium Instruction Schools in Estonia and Norway
Authors: Kapranov Oleksandr
Published: May 2021

This article introduces and discusses a study that aims at illuminating discursive representations of education for sustainable development (henceforth – ESD) by means of compiling and analysing a corpus of policy documents written by English medium instruction (EMI) secondary schools in Estonia and Norway, respectively. Informed by the constructivist approach (Foucault, 1981), discursive representations of ESD in the study were operationalised as discursive strategies that were employed in naming, referring to, and providing an evaluative perspective to ESD-related topics. In this study, the corpus of policy documents published by EMI secondary schools in Estonia and Norway was collected in order to analyse discursive representations of ESD by means of applying a qualitative content analysis. The results of the analysis indicated that the discursive representations of ESD were similarly construed in policy documents written and communicated by EMI secondary schools in Estonia and Norway. Those findings were further discussed in the article in conjunction with their didactic implications.

Lifelong learning emerges as an important dimension in the implementation of sustainable education policies of countries. The conception of developing citizenship competencies, which is at the centre of social studies, plays an important role in shaping the lifelong learning process. The purpose of this study is to analyse the lifelong learning tendencies and teacher self-efficacy levels of social studies teacher candidates in terms of different variables and to determine the relationship between social studies teacher candidates’ lifelong learning tendencies and teacher self-efficacy levels. The study group of the research consists of 307 social studies teacher candidates studying at the education faculty of a public university in the 2016–2017 academic years. The data collection tools used in the research, which was designed in relational survey model, are “Lifelong Learning Tendency Scale” developed by Diker Coşkun (2009), “Teachers’ Sense of Efficacy Scale” adapted into Turkish by Çapa, Çakıroğlu and Sarıkaya (2005) and a Personal Information Form prepared by the researchers. The data of the study are analysed using SPSS 24 statistical software. As a result of the research, it is found that the lifelong learning tendency levels of the social studies teacher candidates are high and their teacher self-efficacy levels are very high. Lifelong learning tendencies and teacher self-efficacy levels of teacher candidates show statistically significant differences in terms of grade level, and taking education for personal and professional development. It is concluded that teacher self-efficacy levels of teacher candidates are a significant predictor of their lifelong learning tendencies.

Authors: Çayak Semih
Published: May 2021

Sustainable leadership is a field of research in which a lot of research has been done recently. In this study, the effects of sustainable leadership behaviors of school principals on teachers’ organizational commitment and job satisfaction were examined based on teachers’ opinions. The sample of the study consists of 338 teachers working in three districts of Istanbul. Sustainable Leadership Scale, Organizational Commitment Scale and Job Satisfaction Scale were used in the research. Research data were analysed by arithmetic mean, standard deviation, correlation analysis and stepwise regression analysis. According to the findings, teachers’ organizational commitment, job satisfaction, and their perceptions regarding sustainable leadership behaviors of school principals were found to be at a high level. As a result of the stepwise regression analyses, the economic sustainability sub-dimension of the sustainable leadership scale was found to predict teachers’ job satisfaction. On the other hand, it was determined that the managerial and social sustainability sub-dimensions significantly predicted teachers’ organizational commitment. The findings obtained were discussed in the light of the related literature and suggestions were presented.
From the “Greta Thunberg Effect” to Green Conversion of Universities: The Reconstructive Praxis of Discursive Mobilizations
Authors: Feldman Jonathan Michael
Published: May 2021

This paper investigates how one could envision a discursive mobilization process to transform protest movements into agents that help reconstruct the universities as agents supporting material mobilizations leading to ecological reconstruction. After reviewing universities’ ecological footprints, the author shows how theories of mobilization and conjunctures could contribute to understanding how this transformation could occur. Discursive mobilizations advance values or ideas but stop short of innovation and production system changes. Material mobilizations affect deployment of human, technological, industrial and financial resources. Conjunctures involve linkages of political activity to spaces implicated in both kinds of mobilizations in a given historical time frame. The study shows many nations having both extensive climate activism and concentrations of university students creating a possibility for greening education centers based on various models for doing so. Yet, two key problems emerge. First, some nations lag in climate activism. Second, interest in a Green Deal or Green New Deal does not always match the level of attention to leading activist Greta Thunberg. The paper illustrates how such problems can be addressed by university-based campaigns linking activist cohorts, mobilization supporting green conversion of higher education and solidaristic, mutual aid exchanges among regions.

Published: May 2021

Introduction

Leishmaniasis is a life-threatening zoonosis of which dogs are the major reservoir and sandflies are the vectors. Until now, the prevalence of canine leishmaniasis (CanL) in the Slovenian dog population was unknown.

Material and Methods

Epidemiological data, eye swabs and blood samples were taken from 465 dogs born in Slovenia and older than one year. Commercial ELISA kits and real-time PCR were used. For ELISA-positive samples, an immunofluorescence antibody test (IFAT) was performed. Descriptive statistics were used to characterise the samples. The one-sample nonparametric chi-square test was used to test whether the categories of a variable were equally distributed.

Results

A 59.9% proportion of the recruited dogs had travelled to endemic regions and 62.1% of them had not been protected by insect repellents. Skin symptoms that might be CanL-related were described in 109 of the dogs’ histories (23.4%), inappetence and/or weight loss in 25 (5.4%), and anaemia, intermittent fever, and/or lymphadenopathy in 19 (4.1%). At the time of recruitment, all dogs were asymptomatic. All samples were PCR negative, nine (1.9%) were ELISA positive, but none were IFAT positive. Five of the nine ELISA-positive dogs were non-travellers.

Conclusion

We conclude that the seroprevalence of canine leishmaniasis of 1.9 % in the autochthonous Slovenian dog population may pose a risk of endemic spread of the disease.
Perspetivar a Integridade Depois do Fim da Natureza
Authors: Carvalho Magda Costa
Published: May 2021

The expression “end of nature” has been coined by American environ-mentalist Bill McKibben is his 1989 famous book, The End of Nature. Since then, the philosophical implications of such an obituary have been explored, mainly on an ethical perspective over the environment. The conceptual end of nature is one of those implications, in the context of a post-naturalistic environmental philosophy. Our purpose is to build upon the ambiguities of “nature” and reframe some readings of the concept of “integrity” as a guiding principle in the relation between human beings and the environment.

The introduction of a city bike system, which has become a complement to the public transport system in large cities and mainly in the most crowded city centers, seems to be a very good solution, which may contribute to reducing urban congestion, air pollution, and noise level. In many situations, bicycle transport can solve the deficiencies in public transport, e.g. at nights, during holidays and on days when bus services are operated to a limited extent. The article presents the functioning of the city bike system in Lublin implemented at the end of 2014, including basic information on the system, its advantages and disadvantages, as well as the existing infrastructure and development prospects.
Effect of Cooperation with Universities on the Innovativeness of Tourism Enterprises
Authors: Olszewski Marcin
Published: May 2021

Introduction. Tourism enterprises operating in a dynamic environment mitigate the erosion of competitive advantages by introducing new products, processes or marketing activities. Universities may serve as one of the essential sources of knowledge, enabling tourism enterprises to implement innovations. The article aims to identify the importance of cooperation with universities in driving innovation in tourism enterprises.

Material and methods. To achieve the aim of the paper, an empirical study was carried out on a sample of 383 hotels and tour operators.

Results. As a result, it was found that universities play a relatively minor role in innovation implementation and for inspiring innovative activity. However, the role of universities is highly diversified. For almost one-third of the entities, universities are important for innovative activities – they play a greater role in large entities, belonging to chains and operating longer on the market. It has also been identified that incremental and marketing innovations are most frequently created due to cooperation.

Conclusions. Results indicate that for increased universities’ role in innovation, companies’ resources and absorption capacity are required. The article also suggests further directions of research on relations between universities and tourism enterprises.

Published: May 2021

The most recent generation of the electrical and electronic household and office equipment is far more efficient than its predecessor, but it is still improvable. The smart equipment, when it is used, adds the advantages of the supplementary control functions with the requirements of beeing electrically supplied. By interconnecting the smart devices in a data network, some of the energy consumption occurs even in the non-active states. These states, either a “stand-by” mode or an “off-line” mode, according to the European Committee directives, imposes maximum limits for the electricity consumption, thus an eco-design of the electrical and electronic equipment. The impact of these eco-design requirements on household appliances and office equipment with repercussions in their operation and use, as well as the energy and environmental effects, are dealt in this paper, based on a case study.

Published: May 2021

Teniendo presente que la educación está llamada a repensarse frente a las barreras y oportunidades que actualmente se presentan y que la investigación educativa se erige como una herramienta para la toma de decisiones, tanto de carácter institucional como de los actores que propician transformaciones en este contexto, esta investigación tuvo como objetivo conocer qué papel ocupan el arte, la tecnología y la educación artística en la formación docente, a través de una revisión de los planes de estudio de los programas de licenciatura activos y con registro calificado de catorce universidades colombianas ‑siete públicas y siete privadas‑ y de la indagación sobre la opinión de un grupo de docentes de educación artística de distintos niveles, de colegios del sector público, privado y de alianza público privada en la ciudad de Bogotá, respecto a su formación profesional como docentes y los componentes de arte y tecnología dentro de ella.
Al respecto se pudo concluir que la educación artística se halla en una disyuntiva entre la necesidad de renovación en cuanto al uso de nuevos recursos tecnológicos y el déficit en la manera de articular los propósitos formativos emanados del sistema educativo y las políticas públicas frente a las condiciones materiales y curriculares que presenta y a las cuales está restringida. Finalmente, como limitante de esta investigación puede considerarse la falta de observación de habilidades y destrezas en el uso de la tecnología para la enseñanza de la educación artística en la escuela.

Published: May 2021

El análisis de los datos provenientes del recuento de eventos debe tener en cuenta las herramientas apropiadas para tratar este tipo de variables. Un enfoque válido para hacer frente a esta tarea consiste en el uso del Modelo Lineal Generalizado (MLG). Esto permite trabajar con funciones de densidad como Poisson o binomial negativa. Este trabajo presenta los resultados del análisis de los datos de un experimento realizado en el campo experimental de investigación de Cenipalma ubicada en el municipio de Barrancabermeja (Colombia).El experimento se estableció para evaluar, a nivel de campo, el hongo entomopatógeno Purpureocillium lilacinum como una estrategia para controlar la población de la chinche de encaje, Leptopharsa gibbicarina. El experimento se realizó en dos parcelas, en una de ellas se implementó el control de L. gibbicarina con P. lilacinum como sugería el programa de investigación de Entomología de Cenipalma y en la otra parcela no se tuvo ninguna estrategia de control. Los datos se analizaron mediante el uso de MLG y dos funciones de densidad diferentes (Poisson y binomial negativa). Los resultados mostraron diferencias estadísticamente significativas entre los tratamientos. El estimador de máxima verosimilitud asociado al tratamiento P. lilacinum indicó que la aplicación del hongo entomopatógeno reduce la población de L. gibbicarina con una tasa de incidencia de 0,28 veces más que el testigo.

Published: May 2021

Saponins in the Cephalaria species have a broad spectrum of biological properties and application potentials. This research aimed to develop a novel method to tentatively identify and quantify triterpenes and saponins in 22 Cephalaria species by LC-HR/MS method. In this study, we provided a broad screening of important biologically active triterpenes and saponins with high separation ability, high sensitivity and high selectivity. This is the first report to prove that Cephalaria species can be a good source of tormentic acid which has many biological activities in literature. The main triterpene compound, tormentic acid was presented at the level between 74.02 mg/kg and 75702.0 mg/kg in n-butanol extract of Cephalaria species. The source of some biologically active saponins such as davisianoside B, aristatoside C, elmalienoside A, balansoide B and scoposide B were also determined with this study, for the first time. Therefore, due to the different activities and usages of the identified compounds, these findings may find application in a number of industries such as nutraceutical, pharmaceutical, medical and cosmetic industries.

Published: May 2021

When India did well to contain the first wave of coronavirus disease 2019 (COVID-19) pandemic, none of us had an inkling of the magnitude that the second wave was going to take. One of the main reasons for the resurgence is several new mutants of this virus – the important ones for our country being UK Variant, Indian Double mutant, South African, and Brazil variants. Questions regarding their impact on virulence, pathogenicity, transmissibility, detection, clinical symptomatology, morbidity, mortality, potential curability, and possibly decreased therapeutic/ vaccine efficacy are being ascertained. We hereby summarize the importance of these variants with respect to Indian scenario, with emphasis on implications regarding COVID-19 diagnosis and efficacy of current vaccines.

Objectives:

We present the survey data on molecular testing and its implications among lung cancer specialists in the South Asian Association for Regional Cooperation (SAARC) region.

Material and Methods:

An online survey Google form was developed that could be completed in <5 min. This was circulated to oncologists who had been actively participated in our academic activities and this data were collected over an 11 day period in November 2020.

Results:

We had 354 responders from 8 SAARC countries, 58.9% (209/354) being medical oncologists, and 30.1% (107/354) radiation oncologists. Nearly 50% of responders were seeing patients in the second wave of coronavirus disease 2019 and 89% had seen reduction in their lung cancer patients during first wave. Biomarker testing in advanced lung cancer using next-generation sequencing as the preferred method was more among medical oncologists (76%) as compared to all the other specialists (24%); (Pearson Chi-square = 0.006). The practice of waiting for the molecular testing report before starting first line treatment was 55.4% in corporate/private hospitals as compared to 27% in the government/charity hospital sectors (Pearson Chi-square = 0.015). A total of 89.6% responders believed that targeted therapy has resulted in improved overall survival in advanced lung cancer.

Conclusion:

Educational activities need to be strengthened so that lung cancer specialists follow comprehensive NGS testing in appropriate settings, as shown by medical oncologists

Published: May 2021

We have studied the growth of three Indian orthopedic journals indexed in PubMed, Scopus, and EMBASE, namely, Indian Journal of Orthopaedics (IJO), Journal of Clinical Orthopaedics and Trauma (JCOT), and Journal of Orthopaedics (JOO). SCOPUS and PubMed databases (2015–2020) were used. The numbers of papers published and citations received to date (since 2015) in these journals were as follows: JCOT (1158 articles; 2060 times), JOO (1070 articles; 2429 times), and IJO (888 articles; 1872 times). The publication and citation trends are rising for JCOT and JOO and have been constant for the IJO. All three journals have seen significant growth and have acted as torch bearers of knowledge shared by orthopedic surgeons in India and Asia.
The Concept of Time in the Dramaturgy of “The Tsar’s Bride” by N. A. Rimsky-Korsakov
Authors: Горячих В.В.
Published: May 2021

В статье рассматривается сюжетное (событийное) и психологическое время в драме Л. А. Мея «Царская невеста» и одноименной опере Н. А. Римского-Корсакова, анализируются изменения, внесенные композитором и либреттистом И. Ф. Тюменевым в литературный текст. Если в драме акцентируется настоящее время — линейное, однонаправленное, то в опере — в ключевых для драматургии сценах — время ретроспективно, обращено в прошлое. Мир прошлого, воспоминаний — идеален, настоящее же несет героям оперы смертельную угрозу, а будущего — нет. Такая интерпретация времени позволяет композитору при полном сохранении сюжета драмы создать в опере свою, оригинальную драматургию

The article deals with a concept of plot and psychological aspects of time in a play by Lev Mei “The Tsar’s Bride” and an opera of the same name by Nikolai Rimsky-Korsakov. The changes made by the composer and librettist Ilya Tyumenev in the literary text are analyzed. While in the drama the emphasis is on the present time — linear and unidirectional, in the opera especially in the key scenes — time is retrospective. The world of memories is perfect, the present is a deadly threat to the heroes of the opera, and there is no future for them. Such an interpretation of time allows the composer, while fully preserving the plot of the drama, to create his own original drama in the opera.

The New Term of the Theory of Polyphony
Authors: Бершадская Т.С.
Published: May 2021

В статье предлагается ввести в научный обиход новый термин — политон. Термин призван обозначить неаккордовое созвучие, которое не образует единую логическую сущность и функционирует в полифонической многоголосной ткани. Логическая разобщенность тонов отражена в самом термине. Использование термина политон намерено создает ассоциации с такими понятиями, как политональность или полиаккорд.

The article proposes to introduce a new term — Polyton into scientific use. The term is intended to denote a non-chordal consonance that does not form a single logical entity and functions in polyphonic tissue. The logical disunity of tones is reflected in the term itself. The use of the term Polyton intentionally creates associations with such concepts as polytonality or polyaccord.
History of Music as a System Object: View from the Nineteenth Century (Based on the Works of Alexander Nikolaevich Serov)
Authors: Дегтярева Н.И.
Published: May 2021

Музыка как искусство, идущее «параллельно с высшими судьбами цивилизации», музыкознание как система дисциплин, историзм как фундаментальная категория и как основа музыкального образования — эти представления составляют ядро музыкально-педагогических и научных воззрений Александра Николаевича Серова. В их совокупности отражается прогностический характер методологических установок выдающегося музыканта, ставших основным предметом обсуждения в настоящей статье.

Music as an art, going “in parallel with the highest destinies of civilization”, musicology as a system of disciplines, historicism as a fundamental category and as the basis of music education — these ideas form the core of Serov’s musical, pedagogical and scientific views. As a whole they reflect the prognostic nature of methodological guidelines of the outstanding musician, which is the main subject of discussion in this article.
Alea Technique of Pierre Boulez: between Order and Chaos
Authors: Переверзева М.В.
Published: May 2021

Статья посвящена технике письма Пьера Булеза — ограниченной алеаторике, в которой композитор стремился сочетать случайность с конструктивной идеей, связанной с серийным методом сочинения. В работе рассматриваются эстетические, композиционно-технические аспекты алеаторики Булеза, ее связи с подобными явлениями в других видах искусства, а также анализируются алеаторные сочинения французского авангардиста с подробным разбором как самого материала и принципов его развития, так и формы с точки зрения степени ее мобильности и структуры. Какими бы подвижными ни были музыкальный текст и форма в партитурах Булеза, они складываются при условии четкой художественной концепции и структурной организации опуса. Несмотря на множественность вариантов формы сочинений, слушатель узнает их в каждом исполнении по неповторимому авторскому материалу и той художественной концепции, которая отражена в каждой «версии» формы.

The article is devoted to compositional technique of Pierre Boulez, to limited aleatory music in which the composer tried to combine chance with the constructive idea connected with a serial method of the composition. The article considers the esthetic, compositional and technical aspects of aleatory music of Boulez, its relation with the similar phenomena in other arts and also analyzes aleatory compositions of the French avant-gardist with detailed analysis of the material and principles of its development, form and degree of its mobility and structure. Whatever mobile were the musical text and the form in Boulez’s scores, they are admissible subject to the strict art concept and the structural organization of the work. Despite plurality of the forms options of compositions, the listener recognizes them in each performance by means of unique author’s material and art concept which is reflected in each “version” of the form.
New Documents on Anton Rubinstein from Foreign Archives
Authors: Власова Н.О.
Published: May 2021

Статья посвящена новым документам из архивов Австрии и США, связанным с А. Г. Рубинштейном. Обзор источников, хранящихся в Архиве Общества друзей музыки (Вена), касается деятельности Рубинштейна на посту артистического директора Общества в сезоне 1871/72. Публикуются два обнаруженных письма Рубинштейна к И. Брамсу. В фондах Венской городской библиотеки в Ратуше выделяются пять писем композитора к австрийскому писателю М. Гартману о совместной работе над неоконченной оперой «Росвита» (1864–1865). К венскому этапу относятся и два контракта Рубинштейна на концертное турне по США в сезоне 1872/73. Эти документы, найденные американскими учеными в архивах США, ранее не были известны российским музыковедам.

This paper presents new documentary materials on Anton Rubinstein from Austrian and U.S. archives. The documents from the Archive of Gesellschaft der Musikfreunde in Wien are related to his engagement as the artistic director of this organization in the 1871/72 season. Two newly discovered letters by Rubinstein to J. Brahms are published and the two composers’ complicated relationship is discussed. Five Rubinstein’s letters to the Austrian writer M. Hartmann from Vienna City Library shed light on their collaboration on “Roswitha”, an unfinished opera (1864–1865). Rubinstein’s two contracts for the American concert tour in the 1872/73 season date from his stay in Vienna in 1871–1872. These documents, discovered by the American scholars, have remained unnoticed by Russian researchers up to the present time.
