The present research feature the content structure of public and extracurricular videolectures compiled by university professors (n=30) and assessed by university students (n=543). The research included such parameters as interaction, presentation, and illustration. The students evaluated videolectures performed by unfamiliar lecturers according to the following parameters: content, professional applicability, interest, and readiness for further  independent study. The students’ assessments of the lectures content and usefulness were most sensitive to the way the content was organized. An extracurricular videolecture was rated higher if it was aimed at conveying information and included minimal amount of terminology and references to the lecturer’s own professional experience, while a public videolecture was rated higher if the lecturers saturated it with scientific terminology and examples from their professional experience. The public and extracurricular videolectures were analyzed from the point of view of their applicability for higher education. 

 The present research featured on-line behavior during the COVID-19 pandemic. As the situation escalated, the number of information requests related to the pandemic decreased, and the content characteristics of search queries became relatively independent from official statements of the Russian government. Early in the epidemic, the content of mass search queries shifted towards positive information as a result of the counter-regulation effect, which required the introduction of personal and situational predictors into the analysis. The main stage of the research revealed an obvious personal / collective dichotomy
and the ambivalent nature of risk assessment, responsibility attribution, and subjective control. COVID-19 patients and healthy users demonstrated little difference in the on-line search behavior; however, the difference in their current affective state was quite significant. The problem-oriented strategies of proactive coping (reflexive, strategic, and preventive coping) were connected with emotional preferences in information search, while personal involvement  was one of awareness parameters. 

 In this article, the authors reviewed foreign publications on the issue of moral injury, its causes, diagnosis, and psychotherapy. Foreign experts do not consider this phenomenon as a mental pathology. They define it as a syndrome characterized by a sense of shame, guilt, and obsessive thoughts as a consequence of one’s inability to prevent one’s own actions or the actions of other people. The authors made an attempt to compare and contrast the concepts of "post-traumatic stress disorder" and "moral injury". The review also featured psychotherapy of moral injury and methods of psychological first aid to different categories of people, e.g. psychologists, medical workers, and others. Unfortunately, the issue of moral injury still remains largely understudied in domestic science. 

 We are currently witnessing radical changes in the science of psychology. The author believes that the psychology of the future will not center on culture, history, and society. Psychology used to individualize society. Instead, it will focus on nature, and its main objective will be to individualize an individual. Psychology lost the battle for human development. Psychology was not convincing enough in its mission, i.e. to coordinate different levels and norms of human life, to direct the path of personal development, to reduce the risks of human activity, to support the process of authentic  identity formation, etc. The new image of psychology will be based on the legitimization of psychological knowledge on the principle of natural conformity, as psychological phenomena will be embodied on all levels of  life. 

 The research featured such an understudied issue as psychological safety in class, which currently lacks diagnostic tools. Standard tests cannot measure the relevant competencies of future teachers. The research objective was to determine the diagnostic potential of the case method in assessing the readiness of future teachers to provide psychological safety in the class environment. The study relied on the ideas about the psychological safety of the educational environment (I. A. Baeva) and the structure of teachers’ professional readiness (N. V. Kuzmina). The study involved 418 students of psychology and pedagogics who had to find solutions for case situations. The cases consisted of the case description and four tasks, the answers to which described certain aspects of the readiness to provide psychological safety in class. The results were subjected to a content analysis. The case method proved a reliable tool for assessing the professional readiness and competencies of future teachers. 

 The image of the world is a set of space-temporal and value-semantic chronotopic components. It is a functional system of psychological adaptation to the constant changes in the human lifeworld. The COVID-19 pandemic is a model of severe changes in lifeworld and lifestyle. The research objective was to identify the chronotopic characteristics of the image of the world in a crisis. The study was conducted twice, i.e. before the outbreak and during the period of maximum restrictions, and featured 92 people. The COVID-19 pandemic transformed the structure of the image of the world. The changes occurred in the orientation of the identification of one’s characteristics, followed by a certain reorientation of these characteristics from the national and civil identity to the human one. The family-role components of the self-image became more significant. The past perspective expanded, while the future perspective shrank. The emotional  coloring of the present became more negative, the past was seen as positive, while the future appeared moderately optimistic. All three time modes proved to be more event-filled. These processes were observed against the background of the polarization of value preferences. The level of meaningfulness of life showed multidirectional dynamics, probably, as a result of different crisis-coping mechanisms with different levels of productivity. The pandemic restructured all components of the image of the world, which had a mobilizing and productive character. 

 The research featured nuclear models of pronominal interrogative sentences with direct word order in the English language. The use of non-inverted interrogative structures depends on the analytical character of English. The  partial subjectpredicate inversion is the main means of interrogativity. However,  interrogative sentences with direct word order are quite common in colloquial English. The violation of the inverted word order reflects the phenomenon of language economy and can be explained by expressive and stylistic tasks. Although violation of word order in declarative sentences is a popular research topic, the subject-predicate inversions in interrogative sentences remain largely understudied in domestic and foreign linguistics. The research involved a modified corpus analysis. Based on the Corpus of Contemporary American English, the author established the frequency of pronominal interrogative structures with direct word order, analyzed their grammatical features, and defined the most popular genres, which appeared to be the discourse of television and cinema. The obtained results make it possible to develop a formal classification of non-inverted pronominal and non-pronominal constructions. 

 The article introduces a comparative analysis of the images of language consciousness that arise in native speakers of German and Russian as reactions to the lexeme Instagram. The vocabulary associated with this social net remains understudied in Russian linguistics. The research was based on a free associative experiment and compared verbal reactions of German and Russian native speakers aged 20–25. The core of the associative field Instagram appeared to be similar for both linguacultures. For Russian respondents, the core of the associative field of Instagram involved such frequent reactions as video, advertising , stories, photos, blogger, animals, business, food, subscribers, etc.; for German participants – Werbung (advertising), Bilder (pictures), Fotos (photos), Informationen (information), Videos (video), Essen (food), Fake (fake), Filter (filter), Posten (posts). The main difference was that the former saw Instagram as a means of earning (money, business, business platform, self-promotion, shop, etc.), while the latter used it for communication (Messenger (messenger), Kommentieren (comment), Freunde (friends). The obtained results can be explained by the global nature of the network, similar interests of its users, and linguistic globalization. 

 The present research featured linguistic metaphors with the somatic component hand as part of the axiological aspect of the image of a gambling addict in Stefan Zweig’s 24 Hours in the Life of a Woman. The research objective was to analyze the linguistic metaphors that verbalize the image of a gambling addict and to describe related evaluative meanings that reflect its axiological aspect. The authors also classified linguistic metaphors with the somatic component hand according to linguistic hierarchy, type of transfer, and stylistic significance. Their axiological meanings were represented by sensory, subliminal, and rationalistic evaluations. The image of a gambling addict was based on negative subliminal evaluations with an emphasis on their ethical aspect (moral vs. immoral). The image proved to be a set of positive and negative evaluations, represented by particular evaluative meanings with immoral aspect and verbalized via linguistic metaphors with the somatic component hand. 

 Early journalistic texts are important for a productive study of modern media texts communicative potential. The etitor – reader interaction patterns, in this case, must be considered diachronically. Modern popular science media texts
show the genetic similarity with those of the early days of Russian periodicals.  The research data and illustrative material have changed, but the composition, stylistics, manifestation of the author's personality, and the general intonation remain the same. The academic journal The Notes of the St. Petersburg Vedomosti (1728–1742) was the first Russian popular science periodical intended for readers who wanted to acquire knowledge about the world. The  publishers of The Notes were well aware that interaction with the audience plays the most important role in articles of various information types. Since 1729 in the annual greetings to the reader (the modern "editor’s welcome speech"), phatic speech served as a powerful means of establishing contact with the audience. The phatic potential of the editor’s welcome speech provided the traditional combination of pleasure and usefulness, simplicity and accessibility of presentation. The main phatic features of the editor’s welcome speech included: an easy-going manner of conversation with the reader, the effect of personality-oriented conversations (friendly "you"), expression of concern about the reader’s interests in combination with information value and self-esteem, joking tone and intention to create a favorable communication atmosphere, formation of the friendly circle and association with the audience. 

 The article deals with the structure and composition of texts of current electronic business communication. The research materials included electronic business letters (initial requests in the sphere of travel and hotel service), initial requests on the pharmaceutical, engineering, and technological Internet forums,  and Instagram business communication texts in the sphere of education, real estate, and food. The messages demonstrated evolution of both structure and text architectonics of business letters. The main research methods included monitoring and description combined with the method of comparative language analysis. The structure and composition of electronic business letters and requests on the Internet forums and social networks proved different from traditional business letters due to the text-generating online algorithms. Internet users seem unable to perceive business e-mails, web-forum requests, or social network messages as a segmentable text. Electronic business communication is currently undergoing deformalization and style hybridization as a result of electronic communication peculiarities and liberalization. 

 All communicative situations of using language for scientific purposes form a scientific discourse. The scientific discourse genre is built on the basis of the oral or written text form: scientific written texts form the corpus of scientific written discourse, while audiovisual texts form the corpus of audiovisual scientific discourse. Smaller forms can be part of a larger text, or mega-genre. Oral mega-genres are: conference, forum, and congress, which can be subdivided into various smaller forms. The written scientific discourse has a distributed chronotope, whereas the oral one is tied to a specific time and place. Online forms are characterized by a distributed topos and a specific time. Communicators perform certain discursive roles: undergraduate – consultant; graduate student – reviewer; the author of the article – editorial board, readers. A scientist is a nuclear participant of scientific discourse. The key discourse-forming features of scientific discourse are: regulation, consistency, and structuredness; objectivity, accuracy, and abstractness; polemic; theatricality; intertextuality. The language of scientific discourse is impersonal, with multiple passive constructions. The functioning of scientific discourse is determined
by external social factors, general patterns of communication, internal trends, and developmental contradictions. Each text is polyphonic because it is the result of the interaction of many discursive paradigms that can be systematized in two directions: "vertical" and "horizontal" (from core to the periphery). Three tendencies dominate in the development of scientific discourse: the growth of phatic; displacement of communication activity to the periphery; authorization  of scientific discourse. 

 The paper features the way linguistic means represent character traits in modern films. The research was based on Neill Blomkamp’s sci-fi drama "Chappie" (2005). The research objective was to describe the phenomenon of multiple linguistic features that disclose the linguistic personality of film characters via their free speech. The author believes that the linguistic image of a film character includes categorization of entities aimed at solving creative tasks, which, in their turn, incorporate the genre, stylistic peculiarities, imagery, and emotivity. The method of continuous selection from a film script offered an ample exemplifying material, which underwent cognitive and stylistic analysis. Modern cinema uses genre stylization and imagery, e.g. children’s speech, parents’ speech, classroom language, streetwise discourse, etc. These features depend on the authenticity of a film character and the heuristic explanation of  an unknown concept by means of metaphors. The linguistic image of a film character is formed within the genre-stylistic boundaries of the script, while imagery allows the characters to reach a consensus within the 120-minute chronotope. 

 The anthropocentric focus of modern science makes cognitive studies extremely relevant. Associative processes still remain an understudied and controversial issue. The research objective was to study the mechanisms of cognitive and linguistic activity that take place in the process of forming a conceptual worldview. The study involved a free associative experiment aimed at identifying semantic connections between responses. The  experiment revealed the content of the concept in the mind of the subjects, which were split into two age groups: 10–12 and 18–21 years old. The obtained associative reactions were divided into certain categories by the commonality of values, by which one can judge the latent cognitive processes involved in creating a conceptual worldview. The study also proved that association is not just a representation, but a complex cognitive process, as it involves higher cognitive functions. A conceptual picture based on the obtained associations revealed semantic points of intersection of concepts that create an associative network. 

 The linguacultural concept of family remains understudied in radio advertising. Advertising is a complex sociocultural phenomenon. Radio  advertising lacks visual images: information is provided to the listeners only  at the verbal level. The present research featured 800 commercial radio spots with words family, parents, father, mother, child, children, grandparents, and home. The conceptual analysis made it possible to identify the main and additional semantic components, to reveal the value components of the concept, and to consider advertising strategies and tactics. The lexeme of house proved to be the core of the concept; the subfields of family and coziness were the central components. The interpretation field was represented by such lexemes as furniture, gifts / toys, holidays, entertainment, recreation, sports, and car. In radio advertising, the concept discourse appeared to generate new meanings that go beyond its dictionary definitions. The value picture of the world of native Russian speakers highlights the most significant cultural meanings of value dominants, which are represented by the explication of physical, social, and spiritual values. 

 The present research featured the speech tactics of compliment and response to compliments in young interlocutors. The speech tactics of compliment usually depend on the following factors: communicative goal, communicative situation, speaker’s attitude, gender roles, cultural impact, etc. Depending on the communicative situation, the most frequent speech tactics were: to raise the mood of the recipient, to support them, to show  one’s approval, or just because it was appropriate. Young female respondents were able to mention much more situations when they usually make compliments than male respondents. Depending on the communicative objective, young women much more often made compliments about one’s appearance, something they liked, or one’s character. The impact of Russian culture seems to be in the following opinion voiced by the respondents: compliments must be genuine, so they usually  give compliments only to family and friends. There are different speech tactics of compliment responses: acceptance, acceptance with a comment / joke / reciprocal compliment, self-glorification, ignoring, etc. In an official situation where the interlocutors had equal status, the young men chose to answer with a joke / comment, to ignore the compliment, or used the tactic of self-glorification. The female respondents used such speech tactics as acceptance, acceptance with a comment, a reciprocal compliment, or a joke. While talking to male strangers in an official situation, the young men used the tactic of acceptance with a comment or ignored the compliment, while the young women tended to accept the compliment, answer with a joke, or use self-glorification tactic. When the young men were talking to a woman-stranger, they ignored the compliment, whereas the young women accepted it, answered  with a joke, used selfglorification, or returned the compliment. In an informal  situation, the young men ignored the compliment, demonstrated self-glorification, accepted the comment, or answered with a joke; the young women preferred acceptance with or without a comment or a joke, self-glorification, or a reciprocal compliment. 

 Modern cognitive linguistics considers synonyms as one of the most important means of linguistic categorization and conceptualization of the world. The article features the synonymous paradigm of the implementation of the concepts of persistence and stubbornness in the Russian language. Dictionaries of synonyms contain 65 synonyms of the words persistence and stubbornness (perseverance, firmness, willpower, self-will, intractability, intransigence, etc.). An analysis of their semantic features revealed the composition of the synonymic microfields of persistence and stubbornness, as well as various semantic aspects of these concepts. Both concepts proved to belong to the thematic category of character traits and the volitional activity of a person. Both concepts can express the property of being resistant to external influences. The difference lies in the fact that the concept of persistence emphasizes one’s desire to achieve a certain  goal, labor efforts, and ability not to retreat in the face  of difficulties, while the  concept of stubbornness expresses the defense of one’s position, refusal to  make concessions, tendency to act on one's own, not to succumb to someone else's influence, management, regulation, leadership, discipline requirements, etc. In the evaluative aspect, the concept of persistence mainly emphasizes  positive properties, such as patience, endurance, self-control, etc., while the concept of stubbornness represents such negative-evaluative components as stupidity, cockiness, and meaninglessness. 

 The present research featured the family of words as a complex unit within the framework of military terminology. The article introduces a new method for studying high-frequency English-language military terms, where terminological units are systematized by the family of words. English-language military terminology is constantly changing. As a result, it remains understudied and requires structuring. The research objective was to structure military vocabulary as blocks, each representing a certain family of words. Military term blocks were selected from modern lexicographic sources. The study involved etymological, semantic, and word-formation analyses. The family of words proved to be a microsystem that combines grammatical, word-formation, and lexical relations. The authors structured cognate high-frequency English military terms as microsystems, i.e. families of words with peaks -bat-, -defend-, -arm-, etc. 

 The meanings of inference and admiration in Russian and Persian point out to the indirect references obtained by the speaker. This research featured multifunctional words zhe and tak in Russian and چهand چطورin Persian exclamatory sentences that convey the meanings of inference and admiration. As these words have different grammatical functions, they also convey different lexical and semantic meanings. The research objective was to define the ways such sentences are translated, as well as to study the grammatical functions of the abovementioned multifunctional words in exclamatory sentences. In both languages, these words also proved to be able to express evidentiality. The obtained results can help foreign students in understanding the methods of conveying the meanings of inference and  admiration in Russian and Persian exclamatory sentences. 

 The article is the final part of a major study that featured the life and work of Solomon Kh. Beilin (1858–1942), a Jewish folklorist, ethnographer, and publicist, the Rabbi of the cities of Rogachev and Irkutsk, who was one of the first researchers to collect and systematize the Jewish folklore on the territory of the Russian Empire. The paper focuses on the post-revolutionary Yiddish works of Rabbi Beilin as part of the development of Jewish ethnocultural life in 1920s-1930s in the USSR, Lithuania, and Poland. The author worked in the archives of the YIVO Institute for Jewish Studies (New York) and studied Solomon Beilin’s Yiddish correspondence with the Jewish philologist and publicist Zalman Reisen, as well as with editors of several Yiddish periodicals. The analysis proved that Beilin’s post-revolutionary research was extremely productive, probably, due to the rise of the Yiddish language in 1920s–1930s. In that period, Solomon Beilin was also interested in various philological issues related to Yiddish grammar and spelling. 

 The research featured the development of citizen journalism in Siberia in the early 1920s when the debates around societal challenges spilled onto the pages of periodicals. By focusing on the early New Economic Policy (NEP) narrative in the regional and local media, the author describes the difference between amateur and professional journalism. The campaign to promote the mass media and NEP was contingent on community debate, which addressed people’s worldview. In some cases, editors and citizen journalists used these topics to highlight the efforts of the local authorities and the effectiveness of media narratives. The narratives of the Soviet mass media and the early NEP made it possible to engage Siberians in public activities and develop a better understanding of working processes at the grassroots of the early Soviet society. The research was based on an interdisciplinary approach, which encompassed the history of everyday life and the relevant issues of journalism. 

 In the summer of 2020, the steppe detachment of the archaeological expedition of the Altai State Pedagogical University explored the territory between the Charysh and the Kalmanka rivers in the Altai Territory. The team monitored 25 mounds of previously identified individual monuments at the top of the watershed near the village of Ust’-Kalmanka. They interpreted the semantics of the burial site from the standpoint of religious and mythical ideas of the Siberian peoples about the so-called world mountain. The scientists compared the semantics of the mounds to the belt symbol. The linear structure of the barrow chain and ditches could be associated with an untied belt, which should have strengthened the mediator functions of the watershed as a sacral landscape that facilitates the rite of passage. The mound chain combined stone-mud and mud structures, probably associated with the cult practices and the multiculturalism of the people that built them. Judging by the external parameters, the mounds were built in the middle or the second half of the 1st millennium BC. 

 The present research featured the development of urban planning policy in small towns of the Krasnoyarsk Territory in 1950s–1960s, when it was designed by the local authorities and included construction, repairs, national, historical, cultural, environmental, and natural features of the terrain, etc. The authors developed some criteria for the classification of small towns and traced the evolution of urban planning policy from individual to mass construction. The new principles that appeared in 1950s–1960s included the natural and climatic conditions and aimed at strengthening the country's defense. The new course of economic, architectural and urban development modernized and changed the structure of the economy in small towns. The research was based on the historical-chronological and geopolitical method that covered the strategic, economic, and socio-cultural development of Siberia in general. The research contributes to the development of urban planning policy and helps to improve city management practices. 

 The article traces the history of the Central Russian honey bee breeding station in the Udmurt ASSR after World War II. The research objective was to determine the main trends and results of beekeeping in the Bolshaya Ucha rural area in the postwar years. The research involved a retrospective analysis of archival materials and annual reports of bee farms. The development of collective-farm beekeeping proved uneven because of poor motivation, labor discipline, and management. In May 1950, the local collective farms merged together to create more favorable working conditions. The reform improved labor productivity, increased mechanization of the most labor-intensive production processes, and lowered production costs. It also developed favorable conditions for the future Central Russian bee breeding farm. 

 The research objective was to describe the role of the North Atlantic Treaty Organization (NATO) and the European Union (EU) in the Libyan crisis. The study was based on the resolutions of the United Nations Security Council, reports of the NATO Secretary General, documents of the EU and FRONTEX, speeches of European politicians, statistics, and publications in the Western press and world news agencies. The article focuses on the reaction of the international community to the suppression of peaceful demonstrations in Libya and the reasons why the USA and the EU authorized the North Atlantic Alliance to lead a military operation. The authors summed up the outcomes of NATO's activities in Libya, analyzed the EU foreign policy instruments in Libya, and evaluated their efficiency. The disagreements between the EU states not only prevented the EU from pursuing an independent and coherent policy in Libya, but also complicated the implementation of the previously agreed measures. The leadership in resolving the Libyan crisis passed to the national states as a result of the weak position of the USA and the EU, as well as NATO’s withdrawal from Libya. The authors concluded that the Libyan crisis confirms the differentiation of roles between the NATO and the EU in the Middle East and North Africa region, in which the NATO resolves military conflicts, whereas the EU is responsible for peacekeeping activities. 

 Introduction. Tell Sabi Abyad is one of the most important archaeological sites in the Balikh basin, located about 30 km south of the Syrian-Turkish border. It consists of four mounds excavated in different seasons. The  excavation was initiated by a Dutch archaeological expedition that started on 1986 and finished in 2010. It was led first by Professor M. Van Loon and then by P. Akkermans.

Methods and materials. The research was based on the results of archaeological excavations, published by the excavation team. The historical reconstruction method was used to study the materials of the site.

Results. The study of excavation materials of the Tell Sabi Abyad monument made it possible to identify the cultural layers, which revealed religious buildings, dwellings, farm buildings, as well as other traces of the long-term human presence. The paper describes chronological layers and the amount of artefacts at different periods. The research made it possible to acquire new facts that can clarify the existing knowledge about Northern Mesopotamia of the Neolithic era.

Conclusion. The study of the monument showed that the houses were built on stable towering platforms, had a regular residential character, and involved bricks, clay, wood, and cane. Most of the houses had a rectangular layout and were connected to each other by small openings (doors). There were also houses with roof entrances. In addition, circular buildings, the tholoi, were found. In the late chronological layers, the era of Halaf culture, the tholoi were widely used not only as places of worship, but also for  housing and food storage. 

 The article presents a historiographic review of "Siberia: XX Century". This interuniversity collection of research papers was published in Kemerovo in 1997–2007. Based on standard research methods and special historical and historiographic principles, the authors analyzed the periodical as a complex historiographic source. The quantitative analysis made it possible to calculate the ratio of the special issues, to assess the editorial board and authors, to describe the research subjects, etc. The semantic analysis was based on the content analysis, which also revealed to what degree the authors of the journal participated in the historical discourse. The paper features retrospective and  prospective analyzes of the main research works of the leading Siberian scientists published in "Siberia: XX Century". The research objective was to identify the patterns of the current historiographic situation based on the state of knowledge of the key historical processes in Siberia. 

 The article features the biography of Professor Nikolai S. Penn, who was the leading specialist in coal enrichment in Kuzbass in the 1930s – 1940s and a successful discoverer of coal deposits in Kuzbass and Eastern Siberia. At the Tomsk Institute of Technology, he organized the work of the mining department, edited scientific journals, and developed Siberian coal science. At the Kuznetsk Research Mining Institute (KuzNIUI, Novosibirsk, Prokopyevsk), N. S. Penn focused on the theoretical issues of coal origin and the mathematical analysis of coal, which made it possible to define coal components, washability, and type. The article also describes Prof. Penn’s personal qualities, as well as  achievements of his famous ancestors who were involved in some major events in the history of England and the United States. 

 The Great War, or World War I, had a major effect on the food situation in Russia and other countries. This aspect still remains largely understudied. The article describes the scale of food supply crisis in Western Europe and Russia, as well as solutions and potential options. It focuses on the antifamine measures taken by the Government of Nicholas II, which were ineffective and slow. As a result, the food crisis escalated and the food supply situation eventually got out of control. The Provisional Government also failed to solve the food supply problem, which passed on to the Soviet government. 

 The present article introduces an elemental composition analysis of copper and bronze alloys from the burials of the Lepeshkinsky Stage of the Tagar culture, burial site Serebryakovo I in the Kiya-Chulym interfluve. The research featured mounds 2, 12, and 16, which date back to 3–1 centuries B.C. The metal composition of 72 items was investigated by inductively coupled plasma atomic emission spectroscopy (ICP AES). The obtained data were subjected to statistical processing, which revealed seven chemical-metallurgical and metallurgical groups of copper-based alloys. The bronze alloys did not depend on the typology of the tools, i.e. knives, engravings, mirrors, deer plaques, etc. The results confirmed the dating of the Lepeshkinsky site between the Saragashensky and the Tesinsky Stages of the Tagar culture. The items revealed a tendency towards a decrease in the proportion of tin bronzes and average concentrations of tin ligatures. The study proved that archaeometallurgical data can help to determine the relative-chronological position of the Tagar culture  burial complexes.
