Authors: Benoumeldjadj Maya , Bouarroudj Nedjoua , Rached-Kanouni Malika , Bouchareb Abdelouahab
Published: December 2024

This study investigates the spatio-temporal changes in Ain Abid (Constantine, Algeria) between 2003 and 2023 using multi-index remote sensing analysis. Through Google Earth Engine platform and Landsat imagery (Landsat 5 TM and Landsat 8 OLI/TIRS), we examined land use/land cover changes and vegetation dynamics using three complementary vegetation indices: Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and Soil-Adjusted Vegetation Index (SAVI). Results reveal significant landscape transformations, including a marked increase in urban areas from 6.90 km² to 19.00 km², a dramatic 98% reduction in forest cover, and a doubling of agricultural vegetation areas. The correlation analysis between indices showed perfect correlation between NDVI and SAVI (r=1.00), while EVI provided complementary information with distinct correlations (r=0.76 and 0.61). Classification accuracy assessment yielded Kappa coefficients of 89.1% and 92.3% for 2003 and 2023, respectively. These findings highlight concerning trends in environmental degradation and landscape homogenization, emphasizing the urgent need for sustainable land management practices in this semi-arid region. The study provides valuable insights for policymakers and land managers in developing strategies for balanced territorial development and environmental conservation in Ain Abid.

Authors: Farhan Basim Abdulkareem , Khalaf Amir. M. , Al-Khateeb Tarik R.
Published: December 2024

This work presents a modeling process for Brushless DC motors (BLDCMs) that considers both magnetic saturation and reluctance variation. DC motors are employed in diagnostic equipment like blood analysers and centrifuges. They enable the rotation and mixing of samples, facilitating the analysis of blood, urine, and other biological substances. Dental Tools: DC motors power dental equipment such as dental drills and handpieces. Two classes of Brushless DC motors were introduced for modeling using MATLAB simulation that involved reluctance variation: the non-uniform air gap model and the uniform air gap model. The characteristics of torque-speed for the two models are studied and compared. Non-uniform air gap mathematical model was subsequently adopted to study the effects of magnetic saturation. When magnetic saturation is incorporated in this work, some constant parameters in the models developed are transformed into variables that are dependent upon current variation.

Published: December 2024

The embedded solar-powered water pump system was considered an efficient irrigation technique for rice fields, and farmers have responded favorably. On the other hand, a complicated assembly process is needed for proper installation. It would require more experienced technicians. The said tests prove that performance is not affected by temperature. For fields of equal size, the system fills a holding tank in 2 minutes and 24 seconds. The study reflected direct proportionality between the field area and the water demand.
An Accurate Ensemble Network with Optimal Architecture for Intrusion Detection Based on Features Representation and Data Augmentation
Authors: Fattah Ahmed Imran
Published: December 2024

Cyber security means protecting Internet-connected systems, including hardware, software, and data, against digital threats. In order to increase cyber security, intrusion detection systems (IDS) based on deep models are accepted as the best methods in the literature. However, these methods often face data set limitations. The datasets used are often unbalanced and of insufficient size. In this research, in order to solve these challenges, a precise ensemble network with an optimal architecture for intrusion detection based on features representation and data augmentation has been presented. In the proposed framework, a pre-processing stage is designed to better represent the dataset's features in the recognition process. Also, in the proposed method, data augmentation techniques have been used in the ensemble network training process to solve the challenge of imbalance and inadequacy of the data set. Hyperparameters of the CNN-LSTM model have also been optimized to create an optimal architecture of the ensemble network. The simulation results on the NSLKDD data set show that the proposed intrusion detection system can classify the type of traffic in terms of normality and intrusion with 94% accuracy.

Published: December 2024

The relevance of the study is due to the fact that young people’s ideas of success characterize their sphere of purposes and aspirations
and serve as a regulator for their concept of self-determination and self-realization in a rapidly and varyingly changing social reality. Success
orientation includes an evaluative interpretation of the results achieved and attitudes towards them, which is conditioned by the need to solve
personal and socially significant tasks. The purpose of the research was to study the structural and content characteristics of students’ social
Structural and content characteristics of students’ social representations of success. The study hypothesizes that the representations success by
student youth is clearly structured, with content characteristics represented by a combinability of orientations towards externalized and internalized success. The research participants are undergraduate students (N = 108) from Sara tov universities (Saratov State University, Yuri Gagarin
State Technical University) aged 19–22 (M = 20.50, SD = 1.5), including 58% females and 42% males. Methods (tools): association experiment
(C. G. Jung) based on the stimulus ‘success’ (requiring to write at least 5 words) , content analysis followed by the prototypical analysis (P. Vergès).
Resu lts: the study has revealed the structure and content of social concepts of success. The content of the core components is characterized by a
combinability of success orientation as a result of achievement of material well-being, as social recognition, and as overcoming of obstacles. The
peripheral representation system includes professional and educational aspirations as well as manifestations of personal qualities (competitiveness, flexibility, resourcefulness) that contribute to sustainable success. Main conclusions: the young people’s representations of success focuses
on external success (social approval, external achievements: material, social status) combined with internalized success (success as a result of
one’s own actions, success as overcoming of obstacles, and success as mental state). Practical Significance: the results can be used in the development of youth programs as well as programs of psychological and pedagogical support for the effective realization of one’s desire for success.

La inocencia de la responsabilidad social corporativa para proteger los derechos humanos ante la inteligencia artificial
Authors: López González Raúl
Published: December 2024

La ética, la filosofía y la ciencia han permitido a la humanidad resolver los desafíos más complejos a lo largo de su historia. La dignidad humana es el fin ulterior de una civilización, tanto el Renacimiento como la Ilustración sintetizan lo mejor de la ciencia y el pensamiento. Por la ciencia y la dignidad humana llegaron la genética, la digitalización, la neurociencia y la computación cognitiva, que trasladan hoy la civilización humana hacia la cuarta revolución industrial. En la dignidad humana se hace imperativo reconocer el legado auténtico de Adam Smith. Sus mayores críticos no han leído su teoría del sentimiento moral, y sus mayores defensores desacreditan que Smith fuera ante todo humanista, luego economista. Los directivos más avezados abrazarán un capitalismo comprometido con la dignidad humana, sin complejos. Este ensayo enlaza capitalismo y tecnología, para enaltecer la privacidad y el trabajo digno.

Authors: Ganapathy S. , Shibi S. , Kanchanarani R. , Jayakumar J. , Veeramani P. , Senthilkumar M. , Murugan P.P.
Published: December 2024

Background: Moth bean is an important dry land crop, requires less water and external input for their cultivation. Even though it has great importance, moth bean cultivation is ignored as minimum attention by the farmers. The major reasons for the low productivity of moth bean was the lack of adoption of improved production technologies and non-availability of high yielding variety seeds, timely guidance from village extension workers. Hence, it is imperative to improve the productivity of moth bean through demonstrations under rain-fed conditions. Methods: With the aims to improve the livelihood of farmers and crop diversification, the field demonstrations of the moth bean variety TMV 1 with integrated crop management practices were conducted by ICAR- Krishi Vigyan Kendra, Villupuram. To improve the productivity of moth bean and farmers income through field demonstrations with improved production technologies compared to groundnut cultivation as farmers practice under rainfed condition. Result: Results on package-wise cost (ha-1) for three years average incurred for land preparation Rs. 9300, Seed cost Rs. 2400, weed management Rs. 9000, plant protection Rs. 8500 and harvesting cost was Rs.15000. The cost of plant protection and harvesting costs are same for moth bean and groundnut and remaining costs are varied for both crops. The yield was 1595 kgs.h-1, gross income Rs. 130000, Cost of cultivation Rs. 46,400, net income Rs. 83,700 and benefit-cost ratio Rs. 2.80. The average cost of cultivation for groundnut cultivation (farmers practice) for the three years is Rs. 76,300; gross income Rs. 1,43,000 and net income Rs. 66,700. Hence, moth bean cultivation proved to be better economically than groundnut cultivation in the rainfed ecosystem of Tamil Nadu, contributing to crop diversification and improved livelihood of farming communities.

Buried valleys of the north-west of the East European Plain: distribution, morphology, geology and problems of genesis
Authors: Krotova-Putintseva A.
Published: December 2024

A lot of buried valleys exist on the territory of the northwestern East European Plain. They are deeply cut in the pre-Quaternary rocks. The buried valleys genesis is a long-standing question of the Quaternary geology of the northwestern Russia. By now, geological data have been accumulated to solve this problem. The geological structure of the buried valleys was detailed on the basis of unpublished reports and published materials on geology of buried valleys of Saint-Petersburg, Leningrad, Pskov, Novgorod and Kaliningrad regions as well as adjacent regions of Estonia, Latvia, Lithuania and Belarus. Most of the data do not exclusively testify to river-erosion genesis of the valleys. Modern data also suggest that some of the buried valleys of the northwestern Russia are tunnel valleys and were formed by subglacial meltwater erosion as well as buried valleys of neighboring regions.
Preparation of tetraethoxysilane for the production of monodisperse spherical silica particles. Part 3. Influence of impurity elements
Authors: Kamashev Dmitriy
Published: December 2024

Nanostructured 3D matrices based on monodisperse spherical silica particles are currently of considerable interest due to the prospects for their widespread use in the synthesis of new nanocomposite materials. At the same time, one of the main problems hindering their large-scale synthesis is associated with the unstable behavior of tetraethoxysilane (TEOS) during its hydrolysis and, as a result, poor reproducibility of the sizes of the formed silica particles under given conditions. In this work, based on the study of the elemental composition of impurities in silica opal matrices obtained from tetraethoxysilane from various manufacturers, we continued to study factors affecting the size of the formed particles.
To solve this problem, samples of supramolecular structures obtained from TEOS from various manufacturers were examined by the ICP-MS method for the content of impurity elements in them. It is shown that the content of elements in the initial TEOS correlates with deviations in the size of the formed silica particles. The experiments carried out on the synthesis of spherical particles with the introduction of additives of a number of previously defined elements confirm the obtained dependence. Moreover, it was found that the presence of certain impurity elements in the system increased the monodispersity of the sizes of the formed silica particles, which was a fundamentally important step to solve the problem of obtaining silica particles of a given size with high reproducibility of results. The obtained results are important for understanding the features of the formation of supramolecular structures of silica in nature.
Influência de metacaulins brasileiros em cimentos álcali-ativados, com mistura ternária de escória de alto-forno e cinza de casca de arroz regionais
Authors: Frare Andreza , Angulski da Luz Caroline , Farias de Medeiros Marcelo Henrique
Published: December 2024

Cimentos álcali-ativados (CAA) são produtos de baixo impacto ambiental, desenvolvidos a partir de matérias-primas compostas por óxido de cálcio (CaO), como a escória de alto forno; sílica (SiO2), como a cinza volante; e materiais compostos por alumina (Al2O3), como o metacaulim. A adição desses compostos aos CAA’s visa melhorar as propriedades físico-químicas desses materiais, garantindo ainda a redução de impactos ambientais da indústria cimenteira. Assim, o objetivo deste trabalho é analisar o impacto de dois metacaulins brasileiros com características distintas na produção de cimentos álcali-ativados, utilizando misturas ternárias que incluem escória de alto-forno e cinza de casca de arroz regional. Para tanto, foram confeccionadas pastas de CAA com proporções distintas de escória, cinza da casca de arroz e metacaulim (MKA e MKB), a fim de manter a relação de SiO₂/Al₂O₃ igual a 4,4. Após realizados os ensaios de resistência à compressão aos 7, 28 e 90 dias de cura, calorimetria isotérmica por 7 dias e análises de microestrutura aos 28 dias, os resultados indicaram que misturas que continham o MKB apresentaram melhores resistências, chegando a 40 MPa aos 28 dias. No entanto, constatou-se que, apesar de graus de amorfismo e composições químicas diferentes entre os dois MK’s, os resultados foram influenciados principalmente pela presença de cálcio na composição da escória, propiciando uma maior formação de produtos hidratados.

Published: December 2024

Pressupõe-se que 2% dos adolescentes que residem nos países desenvolvidos tenham responsabilidades de cuidado com algum integrante familiar. O papel do adolescente em cuidar destaca-se e está aliado a conclusões positivas ou negativas. Portanto, é significativo refletir sobre o que sente o jovem ao cuidar da pessoa idosa e suas relações intergeracionais. Este estudo objetiva investigar os impactos positivos e negativos de alguns cuidados ofertados pelo jovem, com idade entre 15 e 17 anos, ao cuidar da pessoa idosa, exercidos por estudantes da rede pública do ensino médio Escola Técnica de Ceilândia, Distrito Federal. Realizou-se um estudo transversal, quantitativo e descritivo, por meio do instrumento de medida de autorrelato PANOC-YC20 “Resultados Positivos e Negativos do Cuidar”, de origem inglesa, adaptado transculturalmente para o português do Brasil. No estudo descritivo, foram investigados 352 estudantes reconhecidos como jovens cuidadores, sendo 60,90% do sexo feminino, 37,70% do sexo masculino, 0,28% do gênero fluido e 1,12% não binário, os quais responderam a um questionário eletrônico no Google Forms. Foram relatados poucos sentimentos negativos e muitos relatos de sentimentos positivos, o que indica que o jovem cuidador apresenta mais sentimentos e emoções positivas do que negativas ao cuidar da pessoa idosa. Mais estudos sobre os resultados do sentimento do jovem cuidador da pessoa idosa são indicados para que sejam elaboradas políticas públicas para o cuidado de elos emocionais e sentimentais envolvendo a intergeracionalidade, que possam contribuir com a melhora da qualidade de vida e bem-estar tanto do jovem quanto da pessoa idosa cuidada.

Published: December 2024

Trata-se de um estudo transversal cujo objetivo é comparar as dimensões da qualidade de vida entre um grupo de homens homossexuais e heterossexuais na maturidade e na velhice. Utilizou-se um questionário socioeconômico e WHOQOL-bref para a coleta de dados, e estes foram analisados por estatística descritiva e teste Qui-quadrado. Os homossexuais apresentaram melhor escolaridade, sendo que 62,50% possuem ensino médio completo e incompleto; e 37,50%, curso superior. Quanto à renda mensal, os que ganham de 5 a 10 salários mínimos são 27,50% heterossexuais e 10% homossexuais. Os achados revelaram que os homossexuais apresentam numericamente uma melhor qualidade de vida nos domínios psicológico, físico e social; os heterossexuais, uma melhor qualidade de vida somente no domínio ambiental. Em relação à qualidade de vida, não foram constatadas diferenças significativas nas quatro dimensões estudadas. Independentemente do tipo de domínio, a qualidade de vida foi semelhante entre os dois grupos estudados.
Direitos humanos no Novo Ensino Médio
Authors: de Souza Calisto Cristiano , Demo Pedro
Published: December 2024

Este artigo realiza uma análise crítica das recentes reformas educacionais no Brasil, com foco no Novo Ensino Médio e sua interface com os direitos humanos. A pesquisa utiliza uma metodologia mista, combinando análises qualitativas e quantitativas, incluindo uma revisão documental de políticas públicas e a avaliação dos catálogos de Unidades Curriculares Eletivas Orientadas, desenvolvidos pela Secretaria de Educação do Distrito Federal nos anos de 2022 e 2023, usados como exemplo empírico. A educação em e para os direitos humanos é posicionada como eixo central, guiando a interpretação dos impactos das reformas curriculares, especialmente no contexto neoliberal que permeia a Base Nacional Comum Curricular (BNCC). O estudo revela as contradições entre as intenções declaradas e a prática dessas políticas, destacando a perda de protagonismo da temática dos direitos humanos nos itinerários formativos e os desafios em promover uma educação equitativa e emancipadora. A análise crítica também incorpora o conceito de qualidade política na educação, que enfatiza a necessidade de uma educação que não apenas repasse conteúdos, mas que promova a formação cidadã e crítica dos estudantes (Demo, 2023). Conclui-se que, apesar das promessas de flexibilização e inovação, o Novo Ensino Médio enfrenta obstáculos significativos para a promoção efetiva de uma educação que atenda às necessidades dos estudantes em termos de equidade social, direitos humanos e qualidade política.

O objetivo deste trabalho é problematizar as práticas educacionais direcionadas ao processo de alfabetização que desconsideram a autoria da criança em um contexto escolar que prioriza o controle dos corpos em detrimento ao desenvolvimento da alfabetização na perspectiva autoral. Tal percurso passa pela necessidade de compreender as habilidades apontadas como necessárias para que uma criança possa ser considerada alfabetizada. As discussões aqui propostas são embasadas na teoria da autoria da aprendizagem de Pedro Demo (2015), necessária para pensar a alfabetização na perspectiva autoral, e na teoria da docilização e controle dos corpos de Michel Foucault (1999), que, no contexto desta pesquisa, fundamenta a alfabetização domesticadora e gera, por sua vez, uma aprendizagem inadequada. Ainda como aportes teóricos que embasam o desenvolvimento deste trabalho, é importante citar as pesquisas de Demo (2018); Freire (1979); Franco; Martins (2021); Marsiglia (2011); Magda Soares (2003); Nóvoa (2022). A metodologia utilizada é de abordagem qualitativa, fundamentada por Demo (2001; 2011); Oliveira (2008); Bogdan e Biklen (1994), e adota a observação participante (Yin, 2001) como método. Os resultados indicam que a escola, como está organizada, não favorece a autoria do aluno e, por isso, precisa ser recriada tendo em vista o objetivo de alfabetizar de forma autoral.
Rendimiento productivo de Clarias gariepinus alimentados con dietas alternativas
Authors: Llanes-Iglesias José
Published: December 2024

Due to the growing need for new food formulations with local ingredients, the productive behavior of 72 juvenile of Clarias gariepinus (100.16 ± 1.72 g initial weight) fed with different diets during the fattening period was evaluated. A completely randomized design of three treatments with three repetitions and Duncan significance test at 5 % probability was used. The treatments were the control (commercial food, AC) and two humid diets with fishery by-products and broken soybeans and as energy source, one with cassava meal (HY) and the other with wheat bran (ST). The amounts of crude protein supplied per fish were similar between the control and cassava meal diet (78.9, 77.0 y 88.4 g). Growth did not show differences between the diets (final weights of 291.43, 284.21 and 241.29 g). The feed conversion was unfavorable with the humid diets (1.23, 1.81 y 2.21), while the protein efficiency was the same for the control and the diet with cassava meal (2.41, 2.40 y 1.61). Survivals were 100% for all treatments. The economic analysis showed monetary savings due to feeding with humid diets ($ CUP 17,316 y 14,543), since they were made from by-products available in the territory and there was no significant variation in the zootechnical indicators. It is concluded that alternative diets promoted good productive behaviors in juveniles of C. gariepinus, with a positive economic effect.
Strategic Planning of Science and Technology Policy in Conditions of Growing Uncertainty: Challenges for Russia
Authors: Momotova Tatiana
Published: December 2024

The article examines the main documents of strategic planning in the Russian Federation in the field of science, technology and innovation policy, including the Scientific and Technological Development Strategy, Forecast of Scientific and Technological Development of the Russian Federation until 2030, and the Concept of Technological Development of Russia for the period until 2030. Their strengths and weaknesses are assessed as tools for STI management, taking into account the changing external context, increasing uncertainty, the emergence of new global and regional risks. It is shown that strategic planning documents in the field of STI are becoming the main response to “grand challenges”, a tool for monitoring traditional and new threats and risks. The work highlights the importance of STI strategic planning for solving the problems of ensuring technological sovereignty, national security, accelerated and forced scientific and technological development in the context of current external restrictions. The author justifies the need to transform STI strategic planning into a continuous process, supported by the necessary scientific tools for technological foresight, sociological research as well as for financial and economic assessment. The study also covers the documents of strategic STI planning at the level of international organizations and associations in which Russia participates, including the EAEU and the emerging GEP, CIS, SCO, Union State of Russia and Belarus, BRICS. The potential of these documents is considered from the point of view of identifying and supporting advanced joint projects of scientific teams and individual researchers to respond to the needs of the current mobilization stage of science and technology development of Russia and its partners. The possibilities of combining various formats of international cooperation in the field of STI were also considered. The continued relevance of effective STI strategic planning in conditions of growing external uncertainty is confirmed. A general conclusion is made that ensuring harmonization and coordination of scientific and technological development priorities at different levels – from corporate to international – is one of the key tasks for Russia today.
Is a Researcher’s Status a Position or a Title?
Authors: Gromov Oleg , Travin Sergey
Published: December 2024

The article raises the question of the urgent need to reintroduce the academic title of senior researcher in research institutes in order to confirm the level of a specialist and compliance with the position held. We consider the necessity to differentiate between researchers’ positions and their ranks and discuss the topic of unification of academic degrees used in the Russian hierarchy in the field of research with degrees accepted in the international practice. The advantages of the verified system of the table of scientific ranks that existed in the USSR are demonstrated. It is recommended to revive it in modern Russia, since it can really and objectively stimulate researchers to advance in the academic field. The expediency of confirming statuses of researchers with a multifactorial consideration of their positions, academic degrees and titles is shown.
History of the Foundation and Development of the Faculty of Sociology at Russian State University for the Humanities (Dedicated to the Anniversary of Zhan T. Toshchenko)
Authors: Anisimov Roman , Bulanova Marina
Published: December 2024

The article is devoted to the 90th anniversary of the Corresponding Member of the RAS, Doctor of Philosophy, Professor ZhanT.Toshchenko. The authors highlight his efforts for the creation and development of the Faculty of Sociology at Russian State University for the Humanities (RSUH). Historically, the process of forming the Faculty included both the foundation of the university-wide Department of Sociology and the work of the Division of Sociology as part of the Faculty of Philosophy. To date, the Faculty of Sociology has the following departments: Department of Theory and History of Sociology (profile “Digital Sociology and Social Diagnostics” for undergraduate students and “Digital Sociology and Social Analytics” for master’s students), Department of Applied Sociology (profile “Sociology of Marketing” for undergraduate students), Department of Political Sociology and Social Technologies (profile “Social, Political and Management Technologies” for undergraduate students). Graduates of bachelor’s and master’s degree programs can improve their qualifications within the framework of postgraduate studies in order to defend their candidate’s theses in sociology in the Dissertation Council 24.2.366.04. In terms of continuing their professional development, there is an opportunity to defend a doctoral dissertation or join the ranks of the faculty.
RSUH has developed its own model of sociological education. This allows to prepare a universal professional sociologist capable of not only independent judgments and critical thinking, but also of “mastering the craft” of organizing and conducting sociological research. Graduates of the Faculty are successfully employed both in research institutes and in sociological centers that are engaged in applied work. The article shows the process of formation of ZhanT.Toshchenko’s school of thought and reveals the peculiarities of the organization of professional educational and academic activities at the Faculty. The concept of the Faculty of Sociology is based on the paradigm of the sociology of life developed by ZhanT.Toshchenko. It includes a combination of theory and empiricism in teaching disciplines, as well as taking into account the real needs of the labor market; a special personnel selection to hire employees who have a knack for both research and educational work.
The success in the development of the Faculty of Sociology at RSUH is a worthy result of the long-term fruitful activities of ZhanT.Toshchenko and the research and educational team that he have built up among like-minded people.

Authors: Gureyev Vadim
Published: December 2024

The review analyzes the recently published textbook entitled “The Principles of Publication Activities”. It was written by authors who work at Empress Catherine II Saint Petersburg Mining University. Today, this subject area is at its initial phase of development in Russia, while all published study guides predominantly focus only on one of many aspects of publication processes. The main features of the analyzed book include (a) a complex review of the problems, and (b) their description from different viewpoints. It is authored by editors, scientometricians and lecturers, as all of them demonstrate a high level of personal engagement in research and publishing activities. The authors observe all actual issues of modern publication processes in a concise manner but give a sufficient number of illustrative examples and instructions to young researchers regarding preparation of manuscripts, their submission to a journal and further promotion into academic information space. Different types of research documents are thoroughly described, the stages of their preparation are characterized, recommendations on communication with journal editors and peer-reviewers are provided, the topical principles of publishing ethics are depicted, as well as features of functioning and assessment of published papers in different information systems are presented. The textbook will be useful for both young researchers and lecturers who teach students and postgraduates the basics of information and publishing activities.
Assessing Results of University Research Activities: Indicators of Openness in Rankings
Authors: Udartseva Olga
Published: December 2024

Open access to scientific results and research data becomes an engine for the successful development of modern science. The article examines popular rankings of world universities: the CWTS Leiden Ranking, the Times Higher Education World University Rankings (THE Rankings), the QS World University Rankings (QS), the SCImago Institutions Rankings (SIR) and the Academic Ranking of World Universities (ARWU). The objective of the research was to study the ranking methodologies in the ratings under consideration and to determine the place of the openness criteria in them. A comparative analysis of world’s and Russia’s top universities in rankings is provided. The author has made an assessment of the significance of openness indicators in the world rankings, on the basis of which it has been concluded that only two world rankings pay due attention to these ranking criteria. Of those considered, only the evaluation methodologies of the CWTS Leiden Ranking and the SCImago Institutions Rankings take into account a quantitative analysis of open access publications and altmetric impact indicators. The rest of the considered rankings focus mainly on standard bibliometric indicators from different blocks related to the assessment of education, research, academic impact and international cooperation. Thus, in 2019–2022, the University College London (UK) was the top university in the CWTS Leiden Ranking in terms of the share of open access publications (90.8%) and Moscow Institute of Physics and Technology was ranked the first among Russian universities (66.6%).
From the History of Scientometric Citation Classifications. The First Two Works and Russophone Publications. Part 1
Authors: Lazarev Vladimir
Published: December 2024

The apparent diversity of citation motivations and the idea of possible differences in citation functions led to the first attempts at scientometric classifications of citations as early as in the 1960s (i.e. at the dawn of the appearance of a toolkit called the Science Citation Index). These classifications were developed based on the assumption that their application would make it possible to obtain more accurate data on both characteristics of cited documents and the very nature of scientific citation. They were also supposed to help refine information retrieval. The creation of such classifications is considered here in the context of the need for a correct understanding of the reflection of the properties of scientific documents by their citedness. In this work, the two very first articles on this topic are analyzed. Therefore, they contain the first proposed scientometric citation classifications.
