The Effects of Participating in International Mobility for Russian Scientists

Since the collapse of the Soviet Union and the opening of borders, numerous measures have been taken to internationalize Russian science. In particular, publications in journals that are listed in international scientific citation databases have become a point of closer focus. Universities and scientific organizations began inviting foreign professors and sending their own staff and students abroad on international internships. After the start of the Special Military Operation in Ukraine in 2022, Russian science faced numerous sanctions that entailed a reduction in international cooperation. However Russian scientists have accumulated 30 years of experience in active participation in international cooperation and academic mobility. Nevertheless, there is still a significant lack of understanding of how this experience will impact the scientific careers of Russian scientists going forward. In this article, the authors present the results of a study dedicated to exploring this issue. The theoretical framework for the analysis is based on such a concept as “the Three Careers of an Academic” (organizational, cognitive, and community careers) proposed by German experts in sociology of science Johan Gläser and Grit Laudel. The empirical data used in the study include materials from in-depth interviews with young scientists under the age of 39, collected in 2020–2021 as part of a project known as “International Mobility of Russian Young Researchers”, as well as the results of a sociological survey of 7,255 highly productive scientists conducted under the “Monitoring of education markets and organizations” in 2022. All respondents had spent more than three months abroad. The study revealed that international mobility has a comprehensive impact, noticeable in all three components of a scientific career. Acquired knowledge and skills, as well as involvement in international projects contribute to the development of a researcher’s cognitive career, while new professional connections promote advancement in the international scientific community. As for the “organizational dimension” of a career, mobility does not have a direct influence on career advancement. However, mobility often leads to personal changes, particularly influencing one’s determination to switch jobs and seek better conditions. These assessments are presented for the first time and can be useful in developing recommendations for science and technology policies regarding the revision of mobility support programs in light of the new geopolitical reality.

Topic Clusters of Scientific Organizations of Moscow Healthcare Department: Distribution and Leaders

Introduction. Studying the evolution and life cycle of topics that form a particular field of knowledge is important in order to predict certain trends in the development of scientific research in any scientific field (including medicine), as these topics are crucial in identifying and developing new directions. The SciVal topic cluster system is one of the effective, appealing, and promising models for topic-based article classification. It is utilized on the SciVal analytical platform using data from the Scopus international scientific citation database.
 Materials and methods. Data collection and uploading were carried out as of January 24, 2023. The time frame of the study was four years, from 2019 to 2022. The goal was to examine a set of medical publications for 15 organizations (4 research institutes and 11 scientific and practical centers) subordinate to Moscow Healthcare Department.
 Results and discussion. Scientific organizations were ranked according to six scientometric indicators that describe the share distribution and quantitative characteristics of medical topic clusters. The study determined the leaders among all the 15 organizations as well as a top three among research institutes and scientific and practical centers. Topic clusters were analyzed based on the maximum and minimum values in the number of publications and citation indexes across 15 organizations and separately for two groups (research institutes and scientific and practical centers).
 Conclusion. One of the primary paths of future development and implementation of the methods presented in this paper appears to be the use of matrix analysis to identify and determine the key features of both individual subject clusters and joint thematic clusters. With the use of matrix analysis, we will be able to establish the most extensive, referenced, and relevant topic clusters based on the quantitative and equity ratios that we calculate not only between the topic clusters themselves but also between organizations that have publications in these clusters.

Justification for exogenous replacement of magnesium deficiency in women planning pregnancy: experienc of using the drug

Introduction. During pregnancy, the body’s need for most micronutrients increases, and therefore timely detection and adequate correction of deficient conditions are justified, starting from the stage of pre-gravidar preparation.Objective. The purpose of the study is to present literature data on the role of magnesium in homeostasis and own experience of the effectiveness of the use of magnesium preparation.Materials and methods. A review of the literature for 2021–2023 in the databases was conducted in the databases PubMed (the National Library of Medicine), The Cochrane Library, as well as in scientific citation databases (Scopus, Web of Science) The experience of own application of the preparation containing magnesium lactate dihydrate (470 mg) is also presented + pyridoxine hydrochloride (5 mg).Result and discussion. The intake of magnesium into the human body with food is insufficient. Exogenous magnesium replenishment is clinically justified in isolated or associated with other conditions of established deficiency, primarily with intense emotional and physical exertion, sleep deprivation, as well as with emotional lability, palpitations, muscle fasciculations, with magnesium elimination due to iatrogenic exposure or increased demand, for example, gestational-conditioned. Regular use of Magne B6® has demonstrated its effectiveness in the treatment of symptoms of psychological daily stress (fatigue, irritability, deterioration of sleep quality) in women planning pregnancy.Conclusions. The results obtained appear to be important in terms of reducing the risks of clinical progression of somatic symptoms and potential gestational complications, as well as improving the quality of life of childbearing age women who are actively planning to implement their reproductive function.

Priority Development Subject Areas of Global Medical Science

Introduction. One of the tools that allows to assess the relevance of initiated or ongoing scientific studies is the scientometric analysis of their topics. The method is actively and widely used not only for rating models based on various bibliometric indicators and parameters, as well as for evaluating the publication activity of authors, organizations, scientific publications, cities, and countries. Russia and other countries have amassed extensive experience rating accomplishments in scientific and educational fields, specifically using numerous scientometric indicators to assess scientific effectiveness and productivity. The article compiles a scientometric rating of the subject areas covered by “Medicine” in order to identify the priority development directions of global medical science.
 Materials and methods. The study was conducted in the “Medicine” section using the SciVal analytical platform, which uses data from the international scientific citation database Scopus. Four scientometric indicators (scholarly output, citation count, citation per output and field-weighted citation impact) were analyzed for a three-year period from 2019 to 2021.
 Results and discussion. The paper presents a table method for determining the worldwide priority directions of scientific research in medicine. For each of the four scientometric indicators, the TOP-5 subject areas have been identified, the list of which is approximately the same in terms of scholarly output and citation count, but significantly differs in citation per output and field-weighted citation impact.
 Conclusion. The TOP-5 of four scientometric indicators for the period 2019–2021 includes twelve subject areas, such as cardiology and cardiovascular medicine, oncology, surgery, infectious diseases, epidemiology, medical microbiology, public health, etc. The data obtained during the study confirm the strong thematic correlation between publications in certain subject areas. The algorithm described in the paper can be further adopted on local, organizational, regional, and national levels, i. e. in organizations, cities, and countries. This methodology seems to be promising in identifying and analyzing priority areas of scientific research and determining the index of scientific specialization of certain groups of countries, for example, BRICS, G7, G20, EU, ASEAN, Shanghai Cooperation Organization, Eurasian Economic Union, etc.

Противовирусный препарат аллоферон в лечении пациенток с цервикальными интраэпителиальными неоплазиями: обзорный анализ исследований

Aim: Analysis of the published results of scientific studies evaluating the effect of the antiviral drug alloferon on the reduction of viral load (VL) or the elimination of human papillomavirus (HPV) of high carcinogenic risk both in monotherapy of mild cervical intraepithelial neoplasia (CIN) and in complex treatment of severe CIN, as well as to evaluate the effect of the drug on the dynamics of clinical manifestations of CIN. Key points. Eight published domestic studies of the antiviral drug alloferon in the treatment of CIN of varying severity were analyzed. The selection of relevant publications in the scientific citation database PubMed and Google Scholar was carried out to assess the antiviral and immunomodulatory effect of this drug and a cumulative analysis of the results of the treatment of 646 patients with CIN of varying degrees (361 received alloferon, and 285 were in the control group). The average age is 31 years. VL was calculated per 100,000 human cells: less than 3 lg per 105 cells — low, clinically insignificant concentration: from 3 to 5 lg per 105 cells — average, clinically significant concentration: more than 5 lg per 105 cells — high. The effect of the drug on the dynamics of clinical manifestations of CIN was assessed by the results of a cytological study and/or extended colposcopy. Conclusion. The analysis of studies showed the high efficiency of alloferon against HPV in monotherapy (85%: elimination of HPV — 32%, a significant decrease in VL — 53%). Efficiency in complex therapy (93%: elimination of HPV — 89.7%, reduction in VN — 3.3%). The clinical efficacy of the drug in CIN 1 in monotherapy is 79.9%, and in the complex treatment of CIN 2 — 96.8%. Keywords: human papillomavirus, cervical intraepithelial neoplasia, recurrence, antiviral therapy, immunomodulatory therapy, alloferon.

Evaluation of publication activity and analysis of the topic clusters in the subject area «health policy»

Introduction. One of the main factors determining the interest in the study of scientific issues and their development is the availability of publications on the relevant topic, and consequently, the existence of a publication landscape that can be characterized by various scientometric indicators. At the same time, a bibliographic analysis of domestic and foreign sources showed the existence of an information gap in the bibliometric study of the subject area «Health Management» itself. Therefore, it is of particular interest to conduct a general scientometric analytical study on the study of the publication landscape formed by scientific works related to the consideration of theoretical and practical aspects and the analysis of the main thematic clusters from the field of health management.Materials and methods. The study was conducted using an analytical platform (an online tool) SciVal, the data source for which is the international scientific citation database Scopus. The following indicators were selected as scientometric indicators: the total number of publications, the number of publications in the TOP 25% of the most cited, the number of publications in scientific publications 1-2 quartiles, the number of publications in international and national collaborations (cooperation), average citation, citation level. When considering thematic (research) clusters, the main indicators characterizing them are: number, English and Russian names, number of publications, citation level and prominence percentile.Results and discussion. Monitoring and analysis of scientometric indicators can serve as one of the tools for determining the effectiveness of research activities of a particular author, structural unit, organization and the country as a whole. However, such work is impossible without taking into account global trends in the development of medical science and the analysis of global thematic (research) clusters, the identification of which and the identification of priority areas of scientific research in the world, the Russian Federation and Moscow is crucial at the stages of planning scientific activities.Conclusion. The subject area «Health policy» («Health management») is characterized by steady growth and positive dynamics of changes in scientometric indicators reflecting the publication activity of scientists and researchers at the global, national and regional levels, i.e. in the world, the Russian Federation and Moscow.

Development of internal motivation of young people who are involved in programming as a condition of high achievements

Introduction. The internal conditions of activity associated with the development of motivational and personal potentials of a specialist largely determine his success and self-realization in the profession. In this regard, the concept of internal motivation has a high explanatory potential. The lack of foreign and domestic works on the development of internal motivation of young people who are passionate about programming sets the task of generalizing the results of studying the internal motivation of young people in terms of the success of mastering programming as an activity.Materials and Methods. A review of studies devoted to the study of inner youth in the aspect of the success of mastering programming as an activity was carried out in March – May 2022 using the scientific citation databases Scopus, WoS and elibrary. The research was searched using a combination of keywords "internal motivation", "youth motivation", "passion for activity", "passion for programming" in English and Russian for the period 2012-2022.Results. The analysis of the results of studies devoted to the study of the internal motivation of young people in the aspect of the success of mastering programming as an activity allowed us to draw the following conclusions:- programming is a specific type of activity that is not fully reducible to the game, teaching, work;- programming as an activity that is difficult to accurately differentiate, will actualize special mechanisms of professional and personal development of a person, and the development of this activity will be associated with the development of specific personal structures;- internal motivation can be considered as a psychological mechanism for successful mastering by programming and achieving high results in this type of activity;- indication of the inner motivation of young people who are passionate about programming is associated with the study of the perception of the level of complexity of programming, with the determination of the state of flow and involvement in activities.Discussion and Conclusions. Along with this problem and new challenges of objective reality, the search for predictors of successful functioning and positive development of the youth of the Russian Federation, this area of research seems relevant, requiring further detailed study.

Базы данных научного цитирования как фактор разрушения науки в России и в мире

In modern conditions, scientific activity is of particular importance for the development of society. In fact, the success of social development is determined by the level of science in a particular state. One of the most important components of research is their presentation in scientific journals, which are indexed in scientific citation databases. A situation has arisen in which the indexing database of the journal has become almost more important than the content and results of the article published in it. This situation leads to the destruction of science both in Russia and around the world. This statement, of course, requires its own special proof and justification. Based on empirical analysis, it is shown that there are articles in the journals WoS and Scopus with obviously dubious and false scientific results. Historical analysis has shown that these databases are profit-oriented commercial enterprises relying on the resources of the world's leading publishing houses, which led to their success in the competitive struggle. Theoretical analysis has shown that these tools focus primarily on the number of journals and publications, and, consequently, the quality of their scientific articles is questionable. Researchers, instead of free scientific creativity, look back at publication in journals included in WoS and Scopus. National science ceases to exist — the advantages are not obtained by researchers with the best results, but with foreign language proficiency. Scientific work is replaced by competition for the number of publications in journals presented in these databases. The current situation leads to the actual destruction of science in Russia and in the world, since it is primarily a free search for truth, and not competition for social results expressed in publications in journals indexed by commercial enterprises.

Systematization of the factors of consumer participation in the sharing economy

Goal: to systematize the factors of consumer participation in collaborative consumption at different levels of the sharing economy. Methodology: a systematic review of the literature on the topic of the factors of consumer participation in collaborative consumption was used as the main research method. For the analysis, the authors selected studies that were published between January 2012 and May 2022 in foreign scientific journals indexed in the scientific citation databases WoS, Scopus, and Google Scholar. As part of the primary selection, the authors analyzed more than 2 thousand publications on the topic. The most relevant papers for the systematic review of the literature were included in the final sample of 151 publications. Findings: as a result of the analysis, the factors of consumer participation in collaborative consumption are systematized into the following groups: economic, technological, political, legal, social, environmental, demographic, psychological, and hedonistic; in addition, the features of the impact of the COVID-19 pandemic as a separate macro factor are revealed. Each group of factors is described at five levels of the sharing economy: personal, organizational, industry, state, and global. Originality and contributions: from a theoretical point of view, the systematization provides comprehensive information about the factors of consumer participation in sharing at each level of the sharing economy, summarizing a number of existing approaches to interpreting participation factors. Concerning application in practice, the results of the survey may be of interest to companies in the sharing economy sector, since additional information about the interaction of exchange participants at different levels will allow companies to better understand their motives, which will contribute to the development of effective marketing and market strategies, increase sales, strengthen the company’s position in the market and the development of an effective response to the challenges of the external economic environment in conditions of economic instability.

Publication Activity Trends among Russian Researchers in 2016–2020, Based on International Scientific Citation Databases: Web of Science Core Collection and Scopus

Introduction.TheimprovementofRussianresearchers’standingin the global academic space, including the improvement of publication activity indicators, will allow for a better representation of Russia’s scientific achievements. For this reason, this paper presents the results of monitoring the publication activity of Russian researchers, aiming to detect the development trends in Russian science through a comparison of different aspects.MonitoringTools.We monitored the data on the number of articles published by researchers in the Web of Science Core Collection and the Scopus database, comparing our findings across countries and grouping them by STAS priorities, by region (within Russia) and by higher education institution (within Russia). We used themethodsofcomparativeanalysis,groupingsandrankings.Our calculations were based on statistical and mathematical methods. Results.We arrive at a conclusion that the demand for Russian research in the academic community is increasing and that Russia is consolidating its position in the international publication arena, as evidenced by the positive growth dynamics in the number of research articles published inRussia,accordingtotheWebofScienceCoreCollectionand Scopus.Conclusion.The number of articles by Russian researchers (both in general and in the fields prioritised by Russia’s Scientific and Technological Advancement Strategy) continues to increase. At the same time, international citation databases reveal a decrease in the share of articles by Russian researchers in the global publication flow in 2020. One of the reasons behind this trend are the complications caused around the world by the pandemic. The monitoring results can be used for developing a methodology for assessing research activity performance.

THE IMPORTANCE OF CIRCULATING TUMOR DNA IN THE ASSESSMENT OF METASTATIC COLORECTAL CANCER TREATMENT EFFECTIVNE

Challenges in cancer detection, prognosis and management are currently being solved by determining circulating tumor DNA (ctDNA). The assessment of this marker has acquired particular importance in metastatic colorectal cancer (mCRC), the systemic treatment of which depends on the RAS gene status, which has prognostic and predictive value. However, the possibilities of taking samples from the primary or metastatic lesion for pathomorphological and molecular analysis in CRC are often limited. The determination of ctDNA using liquid biopsy has an advantage over standard biopsy due to its low invasiveness and high availability of the method. Analysis of mutations using ctDNA as well as changes in the level of this marker is a criterion for the effectiveness of systemic treatment, as well as a factor that determines the risk of disease progression. Currently, the potential of using ctDNA to monitor effectiveness of first-and second-line chemotherapy, as well as to predict the development of secondary resistance to EGFR inhibitors (cetuximab and panitumumab) in the first-line treatment and assessment of RAS status for returning to therapy with EGFR inhibitors in the third-line treatment of mCRC is being studied. Several pilot studies have provided evidence of the efficacy of EGFR re-treatment. The modern literature data published in leading peer-reviewed journals in Russian and international scientific citation databases, such as Medline, Elibrary, and PubMed were analyzed. Of the 138 analyzed publications, 56 were used to write this review.

The theory of analysis of sharing economy instruments

Subject. The article considers the applied tools of the shared economy, like crowdsourcing, crowdfunding, crowdworking, crowdlanding, crowdtesting, crowdmarketing, and other economic technologies and mechanisms, based on active participation of a large number of consumers. However, there are still no studies on the systematization of theoretical approaches to investigate these tools. Objectives. We focus on developing the scientific principles and ideas that summarize practical experience and show patterns of applying the sharing economy tools. Methods. We analyzed the features of the sharing economy. This enabled to determine the multidirectionality of this phenomenon. The articles with the keywords “sharing economy” presented in the global scientific citation database Web of Science Core Collection for 2015–2021 were grouped into sections, describing the complication of connections between the elements of the sharing economy. Results. We developed scientific principles of accessibility, digital connectivity, customer focus, efficiency, and optimality of using the tools of the sharing economy. The implementation of the developed scientific principles is illustrated by real examples. We suggest scientific ideas of network potential, digital potential, the adapted McKinsey matrix, matrices of project performance, matrices of the balance of production and transaction costs for analyzing the application of sharing economy tools. Conclusions. The theoretical significance of obtained results is in the systematization of principles and ideas of the analysis of sharing economy tools. The practical significance is in the formation of applied tools for the economic analysis of the development of collaborative consumption of products and services in a digital society.

Means of Semantic Compression in Modern English Scientific Discourse (Based on Abstracts to the Articles From International Scientific Citation Databases)

The article explores the phenomenon of semantic compression in small format metatexts within the contemporary English scientific discourse. Abstracts to scientific articles from international citation databases, in particular those of Scopus and Web of Science, are analysed with the aim of eliciting ways of semantic compression. The latter is viewed as a key parameter of a scientific abstract, whose semantic quality is the main factor responsible for further integration of the research results into the global knowledge pool. It is presumed that an abstract, being a secondary small-format text, represents an exact semantic copy of the original scientific article, hence compression is viewed as a mechanism of redistributing the functional load of the eliminated units of the original by means of increasing the informative potential of the remaining elements within the secondary small-format text. In the process of pragma-semantic and discourse analysis, a specific complex of semantic compression methods is revealed on every level of scientific abstract organization; in particular, compression means are elicited on the structural and semantic textual levels, as well as on the morphological, lexical, syntactic and graphical ones. The revealed patterns, on the one hand, expand our understanding of compression mechanisms typical of small-format texts in general; on the other hand, the practical data obtained as a result of the analysis can be used by a wide range of researchers while writing abstracts in English for publications in high-ranking international scientific journals.

Extracting Information on Affective Computing Research from Data Analysis of Known Digital Platforms: Research into Emotional Artificial Intelligence

The topic of affective computing has been growing rapidly in recent times. In the last five years, the volume of publications in this field has tripled. The question arises which research trends are most in demand today. This can only be judged by analysing the publications that present the results of research. Since researchers have access to the entire global scientific publication space, the task of analysing big data arises. This leads to the problem of identifying the most significant results in the subject area of interest. This paper presents some results of the analysis of semi-structured information from scientific citation databases on the subject of “affective computing”.

Russian academic journals (the case study of journals in physics)

The article analyzes the pool of Russian scientific journals in physics presented in the Russian Science Citation Index. The stages of this study are described and presented in detail. A preliminary general list of journals (173) has been formed and a list of journals (113) has been prepared according to the main selection parameters, which make it possible to identify the leading publications, both in their subject heading and in the section "Physics" in general. Based on the current version of the "State rubricator of scientific and technical information", the distribution of scientific journals by subject headings was carried out. Analysis of scientific journals in 12 thematic areas of physics made it possible to draw the main conclusions: on the presence in the VAK List (42 journals); on indexing in scientific citation databases – Web of Science (29 journals), Scopus (34 journals), RSCI (95 journals); for inclusion in the Russian Science Citation Index (54 journals); on the availability of free publication of manuscripts (40 journals); on the availability of royalties for the publication of manuscripts (4 journals).The article is prepared within the framework of the State Order “Development and improvement of the system of Open Archive of integrated information and library resources of Russian National Public Library for Science and Technology as modern knowledge management system in digital environment: on the way to Open Science” № 075-01300-20-00 for 2020–2022.

Upstream Regulator Analysis of Wooden Breast Myopathy Proteomics in Commercial Broilers and Comparison to Feed Efficiency Proteomics in Pedigree Male Broilers.

In an effort to understand the apparent trade-off between the continual push for growth performance and the recent emergence of muscle pathologies, shotgun proteomics was conducted on breast muscle obtained at ~8 weeks from commercial broilers with wooden breast (WB) myopathy and compared with that in pedigree male (PedM) broilers exhibiting high feed efficiency (FE). Comparison of the two proteomic datasets was facilitated using the overlay function of Ingenuity Pathway Analysis (IPA) (Qiagen, CA, USA). We focused on upstream regulator analysis and disease-function analysis that provides predictions of activation or inhibition of molecules based on (a) expression of downstream target molecules, (b) the IPA scientific citation database. Angiopoeitin 2 (ANGPT2) exhibited the highest predicted activation Z-score of all molecules in the WB dataset, suggesting that the proteomic landscape of WB myopathy would promote vascularization. Overlaying the FE proteomics data on the WB ANGPT2 upstream regulator network presented no commonality of protein expression and no prediction of ANGPT2 activation. Peroxisome proliferator coactivator 1 alpha (PGC1α) was predicted to be inhibited, suggesting that mitochondrial biogenesis was suppressed in WB. PGC1α was predicted to be activated in high FE pedigree male broilers. Whereas RICTOR (rapamycin independent companion of mammalian target of rapamycin) was predicted to be inhibited in both WB and FE datasets, the predictions were based on different downstream molecules. Other transcription factors predicted to be activated in WB muscle included epidermal growth factor (EGFR), X box binding protein (XBP1), transforming growth factor beta 1 (TGFB1) and nuclear factor (erythroid-derived 2)-like 2 (NFE2L2). Inhibitions of aryl hydrocarbon receptor (AHR), AHR nuclear translocator (ARNT) and estrogen related receptor gamma (ESRRG) were also predicted in the WB muscle. These findings indicate that there are considerable differences in upstream regulators based on downstream protein expression observed in WB myopathy and in high FE PedM broilers that may provide additional insight into the etiology of WB myopathy.

НАУКОМЕТРИЧЕСКИЕ ПОКАЗАТЕЛИ ПУБЛИКАЦИОННОЙ АКТИВНОСТИ РОССИЙСКИХ УЧЕНЫХ В ОБЛАСТИ ЭКОЛОГИИ (2016-2020 ГГ.)

The article presents the results of scientometric analysis of the Russian document flow in the field of ecology over the past 5 years (2016-2020) based on scientific citation databases (Web of Science Core Collection (WoS CC), Scopus, Google Scholar and RSCI), special attention is paid to WoS CC and Scopus. The leading positions in the number of publications were identified (the first 3 positions are considered): authors, affiliated organizations, funding organizations, branches of science, types of documents, publications. The data on the scientometric indices of the publication activity of Russian scientists in the field of ecology are considered in more detail especially according to such indices as the number of publications, the number of citations, the Hirsch index and the percentile for the RSCI core. The article presents dynamics of the publication activity of Russian researchers in the field of ecology on the considered databases of scientific citation, as well as it gives a comparison of indices and the years in which the largest number of publications are recorded. The study revealed a possible correlation of the international and national events with a surge in the publication activity of Russian researchers. It is noted that the scientometric analysis of the industry document flow allows the solution of following tasks: to identify the most productive authors, to identify organizations whose employees are actively publishing in the area, to highlight the organizations participating in the funding of scientific research in the area under consideration, to determine the branches of science in which scientific research is developing in the area.

FUNCTIONAL FEATURES OF ELECTRONIC SCIENTIFIC RESOURCES

The purpose of the article is to compare the functional characteristics of electronic resources that serve as a medium for accumulating scientific content and evaluating its quality. The methodology involves the use of such general scientific methods as analysis, synthesis, comparison, statistical method. The scientific novelty of the work is the formation of a system of functional features of electronic scientific resources in the context of completeness of satisfying the information needs of the scientific activity support. Conclusions. In order to integrate scientific research into the international information space and to evaluate the quality of scientific knowledge, scientific citation databases perform their main function: to be a tool for forming a single information environment and a source base for information support of the scientific activity and conducting scientometric research. The functionality of search engines and databases is provided by the organization ofscientific content in the following aspects: content coverage, research areas coverage, data representation, search tools. The highest content coverage has a Google Scholar resource that contains the maximum number of types of scientific content. The basic scientific content that is presented in all the analyzed resources is scientific articles. The analysis of the research areas coverage of electronic scientific resources shows that all the analyzed scientific resources are multidisciplinary. Scopus and DOAJ are the leaders in the numberof basic scientific categories. The analysis of electronic scientific resources by the level of generalization of scientific content confirmed the status of Scopus, WоS, Google Scholar and “Ukrainika scientific” as reference resources. The most comprehensive abstract content is provided by Scopus and WоS resources. An analysis of the search engine of scientific electronic resources shows that the most complete search tools are the Scopusand WоS databases. Domestic resource “Ukrainika Scientific” is characterized by a sufficiently powerful search system too. Google Scholar has the least extensive search filter system. An analysis of the principles of evaluating scientific content has shown the widespread use of traditional metrics: both common (Hirsch index) and original within a particular resource. There is a tendency to involve alternative methodologies forevaluating scientific content.Key words: citation database, electronic resource, search engine, scientific content, functional feature, scientometry

Mangrove research in Colombia: Temporal trends, geographical coverage and research gaps

Mangroves are prevalent coastal ecosystems along the Pacific and Caribbean coasts of Colombia, with several structural features and service provisions that make them important regionally and globally. Despite this importance and the existence of national laws to protect them, research on these ecosystems has been historically scarce if compared to the terrestrial ecosystems of the country. Here, we analyse historical trends of mangrove research in Colombia for the time period 1900 until 2018. To do so, a systematic literature search was carried out based on the Web of Science (WoS), Scopus and Google Scholar scientific citation databases. A noticeable increase in the number of mangrove studies in Colombia was found in the 2001–2010 decade. Although the Colombian Pacific contains ca. 80% of the country's mangroves, a greater number of mangrove studies has been conducted on the Caribbean coast. Ciénaga Grande de Santa Marta, a degraded but productive coastal lagoon, is by far the most studied mangrove site in Colombia. Google Scholar was able to capture ~10 times more studies (mostly grey literature and peer reviewed articles in Spanish) than the Web of Science and Scopus databases, indicating the need to include this type of information in systematic reviews. We propose that future mangrove research in Colombia should prioritize: (1) historically understudied areas where degradation threats are strongest (e.g. near planned infrastructure projects), (2) areas poorly examined but likely to contain healthy, carbon-rich and tall mangroves (e.g. most of the Pacific coast) and (3) interdisciplinary studies that provide for a more holistic social-ecological understanding of Colombian mangrove systems. Our broad synthesis approach is applicable to other countries or regions with extensive mangrove areas and it is likely to help scoping future research and conservation efforts in these ecosystems.
