Authors: Tetuev Alim
Published: December 2024

For the first time, on the basis of new archival documents and other sources, the features of the everyday life of students of institutions of higher and secondary vocational education and working youth in wartime conditions are studied using the example of Kabardino-Balkaria. The influence on the daily life of students of the restructuring of the work of educational institutions of vocational education in accordance with the requirements of wartime is revealed. The problems of educational and labor activity of students are revealed. The activities of working youth in helping the front are summarized: participation in partisan detachments, underground sabotage work during the occupation of the republic, raising funds for the National Defense Fund, warm clothes and gifts for the soldiers of the Red Army, providing patronage assistance to military families and orphans. The contribution of urban and rural youth to the development of the economy of the republic in the interests of the front and rear has been studied. Various forms of increasing labor activity and issues of youth participation in the restoration and development of the national economy of the region are considered. It is concluded that the restructuring of the work of educational institutions of vocational education in the interests of the front and rear has significantly affected the daily life of students. Military and physical training, patriotic and labor education allowed them to assist the front and rear and overcome the difficulties of wartime. Despite the limited material and living conditions, the working youth provided significant assistance to the front and socially unprotected groups of the population. In the everyday life of urban and rural youth, work was the main thing. The youth of the home front, showing patriotism and a desire to bring the Victory closer, made a significant contribution to the economy of the region and the country.
INSTITUTIONALIZATION OF THE COLLECTIVE MEMORY OF THE TAIPAS / FRATERNITIES IN THE POST-CONFLICT CHECHEN REPUBLIC
Authors: Osmaev Abbaz D. , Goryushina Evgenia M.
Published: December 2024

This article discusses the formation of collective memory within Chechen tayps, focusing on the underlying mechanisms of this process. It investigates the development of tayp identity and the preservation of traditions in the post-conflict era of the Chechen Republic. The study employs content analysis of 24 sources related to Chechen tayps. The objective is to explore the collective memory of tayps, which underwent significant changes from the Late Middle Ages to the first half of the 19th century, yet remains a steadfast marker of Chechen identity. The subject of investigation is the mechanism of creating, altering, and transmitting collective memory within a tayp. Historically, the formation of tayps’ collective memory relied heavily on oral sources. However, as a result of the deportation of 1944 and the subsequent political crisis in the late 20th and early 21st centuries, tayps experienced substantial loss of their traditional material culture and were partially or completely disconnected from their original places of residence. During the post-conflict restoration period of the Chechen Republic, there has been a renewed interest in the history, genealogy, and societal role of tayps. While oral sources were previously sufficient for transmitting this knowledge, the growing public demand has led to an increase in scientific and journalistic publications. The institutionalization of tayp’s collective memory in modern Chechen society is achieved through the publication of books, essays, and articles about its history, the establishment of internet sites and social media groups, as well as the revival of ancestral towers and villages abandoned in 1944. To strengthen the tayp identity among its members, modern communication tools are utilized, enabling them to maintain contact regardless of their geographical location or country of residence.
PERSIAN COMMUNITY OF VLADIKAVKAZ IN THE CONTEXT OF SOCIOPOLITICAL CHANGES (1917-1930)
Authors: Kanukova Zalina V. , Tuaeva Berta V. , Plieva Zalina T. , Kalirad Ali
Published: December 2024

This article examines the Persian community of Vladikavkaz during the early 20th-century revolutions, the Civil War and its aftermath, repeated shifts in political regimes, and the establishment of Soviet rule. The significance of this study lies in the current magnitude of migration flows, the diaspora’s role as a key actor in international relations, and the limited knowledge available on the Persian community of the North Caucasus during the Soviet era, along with the historiographical situation. Notably, Iranian historians have previously believed that Persians who suffered from pogroms emigrated to their homeland in 1919; the pre-revolutionary Russian sources, with their varied terminology for Persians (Persians, Shiites, Tatars, etc.), have contributed to confusion regarding the ethnicity of migrants. This article introduces previously uncirculated sources that unequivocally demonstrate the presence of a Persian community in Vladikavkaz during the period under investigation, rather than simply an Azerbaijani community. This research employs a historical-systemic methodology, examining all events, plots, and narrative materials as a single process of adaptation by Persian migrants to a new political regime. The analysis of periodicals and official documentation, including meeting minutes and reports from various national structures, reveals practices of “indigenization” towards the Persians. The study uncovers the consequences of transitioning from traditional diaspora institutions to new forms of support for national minorities, and the role these plays in engaging Persians in Soviet society. The findings indicate that the liquidation of the Persian community was the result of several interconnected factors: the curtailment of the New Economic Policy (NEP), the abandonment of the “indigenization” policy, an anti-religious campaign, and a shift in the USSR’s foreign policy towards Iran. These developments collectively undermined the foundations of ethnic entrepreneurship, fostered ethnocultural discomfort, deprived the Persians of their main consolidating center – the consulate – and ultimately led to the deportation of the remaining Persians in the region to their homeland.
PIRI REIS’ MAP OF THE CASPIAN SEA: A HISTORICAL-GEOGRAPHICAL ANALYSIS
Authors: Khanmurzaev Ismail I. , Idrisov Yusup M.
Published: December 2024

This study provides a detailed analysis of the portolan “Bahr-i Khazar” (Ottoman: Sea of Khazar) created by the Turkish cartographer Piri Reis in 1525. The translation from Ottoman into Russian of the preamble and toponymy on the map, along with a comparative analysis of the map’s geographical features with other cartographic materials and written sources, allows for the determination of the possible range and chronology of the sources used by Piri Reis. The research methodology includes decoding cartographic elements, comparing them with historical data, analyzing archival documents, and comparing them with similar maps from the same period. The scientific novelty of this work lies in the fact that this map has not previously been the subject of research in the Russian-speaking academic community. Studying Piri Reis’ map introduces new aspects to the history of the Caspian region, enhancing existing knowledge about the territory and water bodies at the beginning of the 16th century. The authors conclude that Piri Reis relied on Western (Venetian and Genoese) sources available to him, as well as oral reports from travelers, when compiling his portolan of the Caspian Sea. The map contains valuable information about the hydrography and fortifications of the time. The remarkable accuracy of the coastline on the portolan suggests that the Turkish maritime department had a significant interest in the navigation possibilities within the Caspian Sea, which is corroborated by other documentary evidence. The detailed depiction of the coastline around the Caspian Sea enhances the research’s value for understanding the geographical, political, and sociocultural realities of the era. Consequently, the results of this study enrich the cartographic heritage of the 16th century and expand our knowledge of the historical and geographical realities of the region, forming new perspectives for research in the fields of cartography, history, and cultural geography.
THE ORIGIN OF THE ETHNONYMS BURTI AND SULI
Authors: Amirkhanov Hizri A.
Published: December 2024

The ethnogenesis and ethnic history of the peoples of the North-Eastern Caucasus remain a fascinating yet underexplored area of historical Caucasian studies. This article proposes a hypothesis regarding the origin of two ethnonyms: suli, used by the Chechens to designate Dagestanis (particularly Avars), and burti, employed by the Avars to refer to the Chechens. The author posits that the ethnonym suli derives from the Sal (Salar) people, who resided in the foothills of Northern Dagestan until approximately the late 15th century, during the decline of the Golden Horde. This group maintained direct contact with the Avar ethnic community before being assimilated into the latter’s traditional habitat. Fragments of the Sal people, who had settled in the northern Dagestani foothills, gradually integrated into the Avar and Andi (an Avar subethnic group) territories. While the Sal were eventually absorbed, their name persisted in the form suli, used by the Chechens to denote Dagestanis. Ethnic identification in the North-Eastern Caucasus during this period typically involved extending the names of specific adjacent segments of an ethnic community (tribes, clans) to the entire people. In this case, the Avars were the southern and eastern neighbors of the Chechens (in the indicated period, though, this ethnonym did not yet exist). The specific community with which the latter interacted with the Chechens should have been an ethnic group (teip?, tukhkum?) with the root but in its name (possibly pronounced as butoi). This interaction gave rise to the Avar-Andi designation for the Chechens: burtiyal (or buturul). From the second half of the 17th century, the Avars began using the ethnonym chachanal (Chechens) alongside burtiyal, though the latter has not been entirely forgotten. Similarly, the Chechens retained the ethnonym suli for the Avars, which, despite its seemingly obscure history, appears to be explicable through this analysis.
NUR-MUHAMMAD AL-AWARI AND A CRITIQUE OF IMAM GAZI-MUHAMMAD’S VIEWS AND ACTIONS IN A MANUSCRIPT OF HIS WORKS: A SOURCE-STUDY ANALYSIS
Authors: Musaev Makhach A.
Published: December 2024

The archive of the Institute of History, Archeology, and Ethnography of the Dagestan Federal Research Center of the Russian Academy of Sciences houses an Arabic manuscript – a small notebook comprising 20 pages. M.-S.D.  Saidov attributes this manuscript to Nur-Muhammad al-Awari’s legal opinions (taqrirat), wherein he critiques the work (risala) “Iqamat al-Burhan li-irtidad ‘urafa’ Dagistan” (“The Establishment of an Argument Regarding the Apostasy of the Dagestan Nobility”) authored by the first Imam of Dagestan, Gazi-Muhammad al-Gimrawi. Saidov also dates the manuscript to the first half of the 1830s. An examination of the manuscript reveals that its content belongs to the aforementioned qadi of the Avar Khanate, Nur-Muhammad, in which he opposes the ideas and actions of Imam Gazi-Muhammad al-Gimrawi. Nur-Muhammad criticizes Gazi-Muhammad’s interpretations regarding the imam’s authority, takfir, jihad, and hijra. His legal opinions draw upon a wide range of sources, primarily classical works of Shaf’i jurisprudence. The manuscript is an incomplete work. It contains at least two messages from al-Awari addressed to al-Gimrawi, intended for dispatch. The text of the first message spans pages 1-8 and dates prior to 1830. The second part of the manuscript (pp. 9–20) should be attributed to a later period, with the concluding pages dated to 1831. The paper is prefaced with a biography of Nur-Muhammad, illuminating that his legal stance may stem not only from his theological views but also from his role as the qadi of the Avar Khanate, who stood in opposition to Imam Gazi-Muhammad.
ADYGHE OF THE NORTHWEST CAUCASUS AMID REGIONAL POLITICAL SHIFTS (1820-1880)
Authors: Kudaeva Svetlana G.
Published: December 2024

One hundred and sixty years have passed since the tragic events in the Northwest Caucasus that shaped the current state of the Adyghe (Circassian) ethnic group. Today, the Adyghe diaspora far exceeds the population remaining in their historical homeland, raising numerous questions. The most pressing of these concerns is the underlying causes behind this demographic shift. This study examines Adyghe emigration from a new perspective, spanning the three Russian-Turkish wars of the 19th century (1828-29, 1853-56, 1877-78). During this period, fundamental changes occurred in the ethnolocalization, quantitative, and ethnic composition of the autochthonous population of the North-West Caucasus. This research focuses on how the political dynamics altered depending on the outcomes of these wars, the terms of peace treaties, and their impact on state policies regarding Adyghe emigration. This approach aims to reinforce the evidence base of existing conclusions in Russian Caucasian studies. The study employs principles of scientificity, historicism, and objectivity as its methodological foundation, alongside historical research methods such as retrospective analysis and specific analysis. It concludes that the outcomes of the Russian-Turkish wars significantly influenced the political landscape, driving state policies that altered the migration processes and fundamentally changed the ethnolocalization of the Adyghe ethnic group.

Authors:   Education and Research Institute for Business, Economics, and Management of Sumy State University, Putytskyi Anton I.
Published: December 2024

The article analyzes the measures of the State policy aimed at overcoming the problem of income inequality, the main directions of the influence of education on inequality. The main determinants and principles of inequality and approaches to its reduction are visualized. It is determined that the main criteria for assessing economic inequality are the level of income, differentiation of wealth, percentage of accumulation, availability of property, share of small and medium-sized businesses, level of employment, education. Generalization of the achievements of domestic and foreign scholars allowed to allocate priority measures to reduce income inequality, namely: the introduction of a progressive rate of personal income tax for a group of the population with incomes of more than UAH 80 thousand per month and simultaneous exemption from taxation of persons whose income does not exceed the subsistence level; raising the minimum wage in certain sectors of the economy; development of labor market institutions; reduction of precarious employment; increase in the tax rate on dividends; providing targeted assistance to low-income groups of the population and overcoming poverty. A model for reducing inequality in Ukraine has been proposed, which reflects the paradigm of the study in the form of a comparative analysis of postulates and theories that are the quintessence of the generalized contextual concepts of «inequality», «economic inequality», «social inequality», «socioeconomic inequality» which reflect the results of long-term socioeconomic, political and other processes in our country. Institutional mechanisms ensure the support and regulation of a model that has the ability to cycle reproduction and modification, which is a fundamental condition for the existence of socium and society and the basis for their inclusive development. The article also defines the main goals and objectives that must be fulfilled to achieve the goal defined in the model (reducing the level of socioeconomic inequality, increasing the general welfare of the population and balancing the development of the State).

Authors:   Kyiv National University of Technologies and Design, Kleshchov Anton Yo.
Published: December 2024

Eco-industrial parks are becoming increasingly important in the context of ensuring the economic security of Ukraine, especially in times of war. They are an important instrument for reducing dependence on energy imports, improving energy efficiency and sustainable development of industrial regions. The aim of this article is to study the potential of eco-industrial parks to attract investment and ensure the economic stability of Ukraine in the conditions of military hostilities. The objectives of the study include identifying key aspects of the successful implementation of the conception of eco-industrial parks, analyzing international experience in their development, as well as developing recommendations for adapting these models to Ukrainian conditions. The research methods combine system analysis using the induction of world practices and a model approach based on industrial symbiosis. The results of the study demonstrate that the implementation of the conception and the development of eco-industrial parks can contribute to the economic security of Ukraine by optimizing resource flows, reducing greenhouse gas emissions and improving the environmental situation in our country. In particular, through the integration of renewable energy sources and innovative technologies such as blockchain and smart contracts, it is possible to increase the transparency of transactions between park participants and reduce operational risks. The scientific novelty of the study lies in the fact that an approach to adapting the conception of eco-industrial parks in the conditions of wartime in Ukraine, where damaged infrastructure requires special attention to the efficiency of energy and resource use, is proposed. Prospects for further research include the development of a legislative framework to stimulate the creation of eco-industrial parks that meet international standards of sustainable development and are attractive to investors. Further implementation of the conception of eco-industrial parks will contribute not only to economic stability, but also to environmental sustainability, the creation of new jobs and the increase in the competitiveness of Ukrainian industrial enterprises in the world market. The conclusions of this study can be used to further improve approaches to industrial development in Ukraine, especially in the context of the integration of environmental technologies and renewable energy.

Fecal microbiota transplantation from postmenopausal osteoporosis human donors accelerated bone mass loss in mice
Authors: Chen Tinglong , Wang Ning , Hao Yongqiang , Fu Lingjie
Published: December 2024

Objectives

To investigate the effect of gut microbiota from postmenopausal osteoporosis patients on bone mass in mice.

Methods

Fecal samples were collected from postmenopausal women with normal bone mass (Con, n=5) and postmenopausal women with osteoporosis (Op, n=5). Microbial composition was identified by shallow shotgun sequencing. Then fecal samples were transplanted into pseudo-sterile mice previously treated with antibiotics for 4 weeks. These mice were categorized into two groups: the Vehicle group (n=7) received fecal samples from individuals with normal bone mass, and the FMT group (n=7) received fecal samples from individuals with osteoporosis. After 8 weeks, bone mass, intestinal microbial composition, intestinal permeability and inflammation were assessed, followed by a correlation analysis.

Results

The bone mass was significantly reduced in the FMT group. Microbiota sequencing showed that Shannon index (p < 0.05) and Simpson index (p < 0.05) were significantly increased in Op groups, and β diversity showed significant differences. the recipient mice were similar. linear discriminant analysis effect size (LEfSe) analysis of mice showed that Halobiforma, Enterorhabdus, Alistipes, and Butyricimonas were significantly enriched in the FMT group. Lachnospiraceae and Oscillibacter were significantly enriched in the Vehicle group. H&E staining of intestinal tissues showed obvious intestinal mucosal injury in mice. Intestinal immunohistochemistry showed that the expression of Claudin and ZO-1 in the intestinal tissue of the FMT group mice was decreased. The FITC-Dextran (FD-4) absorption rate and serum soluble CD14 (sCD14) content were increased in FMT mice. Correlation analysis showed that these dominant genera were significantly associated with bone metabolism and intestinal permeability, and were associated with the enrichment of specific enzymes. Serum and bone tissue inflammatory cytokines detection showed that the expression of TNF-α and IL-17A in the FMT group were significantly increased.

Conclusion

Overall, our findings suggested gut microbiota from postmenopausal osteoporosis patients accelerate bone mass loss in mice. Aberrant gut microbiota might play a causal role in the process of bone mass loss mediated by inflammation after the destruction of the intestinal barrier.

Introduction

Reports in adults indicate that Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2) infection and vaccination trigger the expression of autoimmune disease such as Graves’ disease, but the incidence of new onset Graves’ disease and its temporal relationship to the peaks of COVID-19 cases in children are unclear.

Methods

This is a retrospective study of children and adolescents with new-onset Graves’ disease diagnosed between September 2017 and August 2022, N=156, mean age of 12.5 ± 4 year (y), with a range of 2.9-17.9y. There were 119 female (76.3%) and 37 male (23.7%) subjects. Subjects were categorized into 2 groups: pre-COVID-19 era Graves’ disease (n=63, age 12.5 ± 3.3y), and COVID-19 era Graves’ disease (n=93, age 12.4 ± 4.4y). We calculated incidence rate based on new cases of Graves’ disease and total number of new patient referrals to our endocrine clinic. We first compared the demographic, clinical and biochemical data between the above 2 groups; and also, between subjects with either a history of COVID-19 infection (n=23) or vaccination (n=17) to a control group (n=63).

Results

The incidence of Graves’ disease was significantly higher during the pandemic: pre-COVID-19 versus the COVID-19 era, n=55, 0.56% vs n=93, 0.9%, p=0.005, after accounting for the total number of annual new patient referrals during the study period. The rise in the cases of Graves’ disease followed the spikes in the number of cases of COVID-19 in NY. There was also a statistically significant difference in the race distribution between the pre-COVID-19 and the COVID-19 era (p=0.026).

Discussion

The incidence of Graves’ disease increased significantly in children living in New York during the COVID-19 pandemic. The temporal relationship between the peaks of COVID-19 cases and the increased cases of new onset Graves’ disease suggest possible autoimmune triggering by SARS-CoV-2.

In this study, we bridge a crucial gap in the literature by investigating the interplay between environmental regulations, technological innovations, and renewable energy adoption and their impact on sector-specific environmental performance in the textile and fashion industry. Leveraging time series data from 1995 Q1 to 2022 Q4 and using autoregressive distributed lag (ARDL) and Granger causality techniques, this research is built upon the environmental Kuznets curve (EKC) hypothesis and regulatory push innovation hypothesis to unravel these complex interactions. Our findings demonstrate that rigorous environmental regulations and taxes are pivotal in enhancing environmental outcomes across various industry sectors, leading to significant reductions in greenhouse gas emissions and particulate matter. However, the total leather and feather production (LFP) and total fashion production (FP) sectors are highly responsive to environmental policy and regulations. Although technological advancements and research and development (R&D) initially increase ecological footprints due to high upfront costs, they are indispensable for achieving long-term environmental improvements and reshaping regulatory landscapes. The adoption of renewable energy sources, meanwhile, delivers immediate and substantial reductions in carbon emissions, highlighting their critical role in advancing industry sustainability. In this study, we advocate for leveraging environmental regulations as drivers of technological innovation and sustainability, urging policymakers to implement incentives for technological progress and renewable energy adoption. The implications of this research are significant for both industry stakeholders and policymakers. By positioning environmental regulations as catalysts for technological advancement, in this study, we emphasize the importance of a proactive, integrated approach to sustainability. Despite the study’s regional focus, which may limit generalizability, future research should include longitudinal and comparative analyses across varied regions and emerging technologies to refine strategies for superior environmental performance.
Expectations of doctoral students in the field of medicine and health sciences towards a graduate school: an online cross-sectional survey in Germany

The doctoral thesis in medicine is a special case, as it is usually started during the course of study and the students have no experience of scientific work. This lack of scientific training is often criticized, and the quality of doctoral theses in medicine is considered low. In order to increase the quality of doctoral theses and the successful completion rate, a structured doctoral programme can provide the appropriate support. A cross-sectional survey of doctoral students in the field of medicine and health sciences was conducted to assess their expectations of a structured programme offered by a graduate school planned for doctoral studies in complementary and integrative medicine (CIM). Among other questions concerning experiences in their doctorate, the participants were asked to indicate their expectations in two free text answers and 24 pre-defined answers (5-point Likert scale). In addition, participants were asked how supervision should be organized in the curriculum. The majority of the participants expected individual personal support and advice in the graduate school, while financial support was not very important for them. In addition to the scientific training, networking and support among the participants of the graduate school was considered important. The non-medical participants were interested in personality development in science and networking with other doctoral students, whereas the medical doctoral students were more interested in scientific guidance. Doctoral students with a CIM topic expected a predicate and a better final grade by participating in such a graduate school. These results provide important information on how the curriculum in the graduate school should be designed. The next steps will be to evaluate the preliminary curriculum in order to develop a curriculum following the six-step approach of Kern.
Anaerobic Faecalicatena spp. degrade sulfoquinovose via a bifurcated 6-deoxy-6-sulfofructose transketolase/transaldolase pathway to both C2- and C3-sulfonate intermediates

Plant-produced sulfoquinovose (SQ, 6-deoxy-6-sulfoglucose) is one of the most abundant sulfur-containing compounds in nature and its bacterial degradation plays an important role in the biogeochemical sulfur and carbon cycles and in all habitats where SQ is produced and degraded, particularly in gut microbiomes. Here, we report the enrichment and characterization of a strictly anaerobic SQ-degrading bacterial consortium that produces the C2-sulfonate isethionate (ISE) as the major product but also the C3-sulfonate 2,3-dihydroxypropanesulfonate (DHPS), with concomitant production of acetate and hydrogen (H2). In the second step, the ISE was degraded completely to hydrogen sulfide (H2S) when an additional electron donor (external H2) was supplied to the consortium. Through growth experiments, analytical chemistry, genomics, proteomics, and transcriptomics, we found evidence for a combination of the 6-deoxy-6-sulfofructose (SF) transketolase (sulfo-TK) and SF transaldolase (sulfo-TAL) pathways in a SQ-degrading Faecalicatena-phylotype (family Lachnospiraceae) of the consortium, and for the ISE-desulfonating glycyl-radical enzyme pathway, as described for Bilophila wadsworthia, in an Anaerospora-phylotype (Sporomusaceae). Furthermore, using total proteomics, a new gene cluster for a bifurcated SQ pathway was also detected in Faecalicatena sp. DSM22707, which grew with SQ in pure culture, producing mainly ISE, but also 3-sulfolacate (SL) 3-sulfolacaldehyde (SLA), acetate, butyrate, succinate, and formate, but not H2. We then reproduced the growth of the consortium with SQ in a defined co-culture model consisting of Faecalicatena sp. DSM22707 and Bilophila wadsworthia 3.1.6. Our findings provide the first description of an additional sulfoglycolytic, bifurcated SQ pathway. Furthermore, we expand on the knowledge of sulfidogenic SQ degradation by strictly anaerobic co-cultures, comprising SQ-fermenting bacteria and cross-feeding of the sulfonate intermediate to H2S-producing organisms, a process in gut microbiomes that is relevant for human health and disease.
