Мы вечно в долгу перед героями, отстоявшими нашу Родину в жестокой схватке с немецко-фашистскими завоевателями.

Ему присущи сильное чувство и твердая цельность поэтического «я». Поэзия Блока отличается трагизмом и героизмом и обладает бесконечным притяжением для российской и мировой культуры. В Блоке гармонично сочеталась острая наблюдательность со способностью к анализу. Беглые повседневные впечатления в поэзии Блока служат поводом постижения и запечатления мира. Блока называют поэтом переходной эпохи. Его поэзия послужила связующим звеном между классической поэзией и поэзией революционного мира. Становясь на свой идеалистический путь, ему пришлось пройти через сложные поиски, преодолеть влияние идеалистических принципов в философии и символизма в искусстве. В творческой лаборатории Блока немало поэтических текстов о цветах, которые являются опосредованными выразителями чувств поэта. В основном в его поэзии встречается экстерьерная флора. Александр Александрович Блок – поэт, чьей поэзии присущи высокая культура, гуманизм, бескомпромиссность, патриотизм и революционность. Эти качества делают поэзию Блока ярким явлением в истории русской литературы.","PeriodicalId":42592,"journal":{"name":"Bulletin of Irkutsk State University-Series Mathematics","volume":"66 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85781479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

В исследовании приняли участие 52 16-летних старшеклассника, которые были диагностированы на основе их уровня мотивации-принадлежности и обследованы на наличие различных личностных качеств. Исследование показало, что индивидуальные качества старшеклассников различаются в зависимости от уровня мотивации-аффилиации. В исследовании использовались различные методы, включая метод Мехрабиана, метод Русалова, опросник Кеттелла, тест Спилберга и метод оценки Томаса для измерения различных аспектов личности. Полученные результаты свидетельствуют о том, что старшеклассники с высоким уровнем склонности к принятию и общению с другими людьми обладают более гибкими и полиморфными связями свойств личности и индивидуальности. Кроме того, была обнаружена прямая корреляция между характеристиками потребности в общении и индивидуальными особенностями старшеклассников. В исследовании также были выделены психологические проблемы, с которыми сталкиваются старшеклассники, испытывающие недостаток аффилиации.

The illegitimacy of the philosophical opposition between the «gradual» Path of the Sūtras and the «swift» Path of the Tantras is affirmed. An approach to the gradual systematization of the Buddha's Dharma is proposed in the relationship of its theoretical and practical aspects, based on Indo-Tibetan texts and the oral commentary tradition, with the recognition of the fundamental importance of the classical Indian schemes for the gradual systematization of Dharma, contained in the Prajñāpāramitā Sūtras, Madhyamaka texts (Nāgārjuna, Āryadeva, Chandrakirti), Maitreya/Asanga's «Abhisamayalamkara», Asanga's writings on the bhūmī, Śantideva's «Bodhicharyāvatāra», Atisha's «Lamp», as well as in the texts of Lamrim by Je Tsongkapa and other authors.

At the same time, the category of small states is not unanimously agreed upon, despite its frequent use in public and scientific discourse by researchers. The aim of this article is to systematize approaches to the conceptualization and operationalization of small states based on absolute, relative, quantitative and qualitative criteria and to analyze their applicability at various levels from global to dyadic ones. The article also seeks to establish the number of small states based on the index of the size of the state developed by the Russian researcher A. V. Travish, taking into account the ratio between states in terms of their population, territory and GDP. Although this approach does not allow delineating the boundaries of qualitatively different subcategories of small states due to their large number, the author concludes that the selection of cases for thicker research should begin with a primary quantitative analysis. Finally, an attempt has been made to classify small states based on geographical and analytical criteria, taking into account the aforementioned index of the size of the state.","PeriodicalId":42592,"journal":{"name":"Bulletin of Irkutsk State University-Series Mathematics","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135402180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been determined that the digital elevation model is most effective method. It allows to more accurately identify the flooding zone boundary according to the elevation marks of the highest water level at the hydrological station. For studying the floods risk the small towns in the Angara River basin in Irkutsk region were selected (Tulun, Nizhneudinsk and Biryusinsk), which located on the floodplain areas of the Iya, Uda and Biryusa Rivers. Biryusinsk is subject to less flooding and consequences due to the location of the town on elevated areas of the right-bank terraces of the Biryusa River valley. Zoning of “Tulun town”, “Nizhneudinsk town” and “Biryusinsk town” according to the flood risk degree was carried out. According to relief elevation marks the four zones have been defined for each territory, which characterized by different degrees of flooding hazard (high hazard, medium hazard, low hazard and no hazard zone). An analysis of the main causes, as well as the structure of the flood zone during the catastrophic rain flood of 2019 in the cities of Tulun and Nizhneudinsk was carried out. He showed that, along with hydroclimatic factors (intense and abundant rainfall, high previous moisture content of watersheds), a significant role in the formation of great damage from floods was played by high population, economic development and development features of flooding areas of the Iya and Uda river valleys. The floods damage in Biryusinsk is less, despite the frequent observation of water levels above the critical level due to the city location on elevated area of the right-bank terraces of the Biryusa river.","PeriodicalId":42592,"journal":{"name":"Bulletin of Irkutsk State University-Series Mathematics","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135957864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
