Comparative analysis of the content of the main groups of phenolic compounds (flavonoids and phenolic acids) was performed for the overground part of Spiraea salicifolia L. from natural habitats in Siberia and the Russian Far East. Populations of plants with the highest content of phenolic compounds were determined to reveal the potential of their use. It was found that the content of phenolcarboxylic acids in leaves (3,59–7,69 %) is higher than that in inflorescences (2,24–5,52 %), regardless of habitat. The distribution of flavonoids between leaves and inflorescences of S. salicifolia is ambiguous. The content of flavonoids ranges from 1,27 % to 5,48 % in leaves, and from 2,34 % to 6,26 % in inflorescences. The highest content of flavonoids and phenolcarboxylic acids was found in plants from Amur region, the Republic of Yakutia, the Republic of Buryatia and the Primorsky Territory. The content of the investigated substances is not high in samples of S. salicifolia from Irkutsk region, Sakhalin region, Khabarovsk region and Magadan region.

В рамках современного подхода к оценке гравитационных зависимостей, на основе применения метода квазимаксимального правдоподобия Пуассона, определены сравнительные значения торговых барьеров, а также сравнительный потенциал расширения торговли регионов Дальнего Востока с ключевыми экономиками Азиатско-Тихоокеанского региона (далее 􀀐 АТР). При соотношении оценок, полученных в рамках традиционного и современного подходов к оценке гравитационных зависимостей, показаны схожие результаты и расхождения. Современный подход к оценке указал на заметный потенциал для расширения торговли регионов Дальнего Востока со странами Северо-Восточной Азии, что подтверждает выводы о наращивании торговых взаимодействий между крупными и близлежащими экономиками в результате либерализации торговли. The objective of the paper is to assess comparative trade barriers between the regions of the Russian Far East and the countries of the Asia-Pacific region based on the modern approach to assessing gravity models, as well as to assess the potential for increasing mutual trade. The author has shown that the countries of the Asia-Pacific region are the largest trading partners for the Russian Far East (RFE), characterizing perceptible differences in the geographical and regional structure of the trade interactions. Since the customs duties on RFE exports are high, it is the main source of the tariff burden on the mutual trade. The findings indicate the following similar results between the traditional and modern approaches: the lowest comparative value of the trade barriers is typical for the trade between the RFE and the Republic of Korea; the trade between the RFE on the one hand and China and the Republic of Korea on the other has intensified; reducing the tariff barriers was not sufficient to boost the trade between the RFE and the Asia-Pacific countries; trade restrictions initiated by the Russian side resulted in a transition from the tariff barriers to the institutional ones; the groups of the RFE regions with similar characteristics of the comparative potential for expanding trade relations with the Asia-Pacific countries were identified. The evaluation shows some differences in outcomes between the two approaches. First, under the traditional approach the trade barriers were generally overestimated, so the estimates using the modern approach were more realistic, reflecting the possible changes in the price of foreign goods. Second, using the modern assessment approach, expanding the trade between the RFE regions and the close markets in the Northeast Asia (Korea, China and Japan) has a greater potential than with the remote countries (USA and South-Asian countries). These assessments support the early findings that trade interactions between the large and neighboring economies has a high potential as a result of trade liberalization.

In this article, the author examines the state and various development problems faced by small settlements, whose livelihoods and very existence are completely dependent on agricultural production. This issue is not fashionable and widespread in the scientific community, but at the same time, it is very relevant for Russian realities. The author conducts his research on the material of the village Ogusur (Teya) of the Syl Nasleg of the Churapchinsky ulus of the Republic of Sakha (Yakutia). This is a very sparsely populated locality located in the Central part of the Republic. At the same time, all the problems that the residents of this village have to solve are typical for many in the largest region of the Russian Federation. Further socio-economic development of such settlements has always looked problematic, and in connection with the transition to the market economy of our country, their very existence is called into question. But for people who have lived on these lands for centuries, this is the only most fertile and desirable place that they will not exchange for any. From the author’s point of view, when certain conditions are created, first of all, the arrangement of their accessibility, these harsh regions can be attractive for young families. The events of recent months show that over time, such places in the Russian far East, where vast territories still remain sparsely populated, may prove very promising for the life of Russians and the upbringing of the younger generation on ecologically clean and free lands.

This article shows how the sensory perception of rock art guided both archeologists’ interpretations as well as indigenous worldviews in Eastern Siberia and the Russian Far East. The research is based on the author’s ethnographic fieldwork research among indigenous communities of the Olekma, Chara, Aldan, and Amur, and Vitim river basins in the Sakha Republic, the Amur and Zabaikalskii regions, and the Republic of Buriatiia. The article discusses Evenki herders’ and hunters’ interactions with the rock art sites and demonstrates how these sites have served as a source of ritual and cosmological inspiration. Rock art research has also been inseparable from intuitive and embodied experiences for researchers in the field who interact with rock art.

Abstract In July 2019, the village of Nizhniy Bestyakh in the Republic of Sakha (Yakutiya), the Russian Far East, was finally able to celebrate the opening of an eagerly awaited railroad passenger connection. Through analysis of rich ethnographic data, this article explores the “state of uncertainty” caused by repeated delays in construction of the railroad prior to this and focuses on the effect of these delays on students of a local transportation college. This college prepares young people for railroad jobs and careers, promising a steady income and a place in the Republic's wider modernization project. The research also reveals how the state of uncertainty led to unforeseen consequences, such as the seeding of doubt among students about their desire to be a part of the Republic's industrialization drive.

The profile and amounts were determined for phenolic compounds in the leaves of Dasiphora fruticosa plants growing in natural populations in the south of the Russian Far East. It was found that the phenolic profiles of the plants are similar among all the analyzed populations, but there are differences in the concentrations of the phenolic compounds. Total concentrations of phenolic compounds, flavonols, rhamnetin glycosides, and free quercetin are 12—46% higher in the leaves of plants of three populations from Shikotan Island. The highest total concentration of ellagic compounds (12.6 mg/g) was noted in the population from Primorsky Krai.
