On the polysemy of a lexical unit in the dictionary and in the context (comparative analysis on the material of explanatory dictionaries and a publicistic text)
Authors: Королева В.В. , Румянцева М.С.
Published: August 2024

В статье рассматривается понятие многозначности, изучается семантическое содержание лексической единицы market и приводится сравнительный анализ значений лексемы на базе четырех толковых словарей. Целью исследования является изучение способов объяснения явления рынка в лексикографических источниках, а также сравнение определений лексемы market, зафиксированных в словарях, со значениями, реализующимися в публицистическом тексте журнала “The Economist”. Актуальность исследования обусловлена необходимостью обновления лексикографических данных о понятии рынка и создания концептуальной модели данного явления в экономике. Делается вывод о связи определений в рамках статьи в конкретном словаре посредством интегрирующей семы или с помощью усиления выраженности эмоционального компонента. Образование переносных значений с помощью метафоры и метонимии часто является предпосылкой развития концепта «рынок». В ходе исследования в текстах журнала были выявлены некоторые значения лексемы market, не упомянутые в словаре.

The article discusses the concept of polysemy, studies the semantic content of the lexical unit ‘market’ and provides a comparative analysis of its meanings based on four explanatory dictionaries. The purpose of the research is to study the ways of explaining the phenomenon of the market in lexicographic sources, as well as to compare the definitions of the lexeme ‘market’, recorded in dictionaries, with the meanings updated in the journalistic text of The Economist. The relevance of the study is due to the need to renew lexicographic data on the concept of the market as an economic institution, since these data allow us to model a conceptual representation of the studied mental knowledge. The conclusion is made about the connection of definitions within an article in a particular dictionary by means of an integrating seme or by increasing expressiveness of the emotional component in the meaning of the word. The development of figurative meanings by means of metaphor and metonymy is often a prerequisite for the development of the ‘market’ concept. In the course of the study, some meanings of the lexeme market, not mentioned in the dictionary, were identified in the journalistic texts.
Development of the satire genre in the works by the classics of Dagestani literature Y. Kazak and E. Emin
Authors: Ханбалаева С.Н. , Халидова Ю.Р.
Published: August 2024

Статья посвящена анализу острых социальных мотивов в лирике Йырчи Казака (1830–1879) и Етим Эмина (1838–1898), чье творчество оказало заметное влияние на развитие жанровых форм в дагестанской поэзии второй половины XIX века, в том числе и жанра сатиры. Цель статьи – показать, как, сохраняя и развивая идущую из глубины веков поэтическую традицию, лирика Й. Казака и Е. Эмина расширила жанровые и стилистические границы дагестанской литературы. Новизна исследования заключается в том, что впервые рассматривается роль классиков кумыкской и лезгинской литературы в формировании и развитии жанра сатиры как важнейшего направления в генезисе дагестанской художественной словесности.

The works by Dagestani classical poets Yirchi Kazak (1830-1879) and Etim Emin (1838-1898) are closely connected with the traditions of national folklore, eastern artistic cultures, as well as with the political and cultural processes of Dagestan and Russia in the late XIX century. The main objects of the study are satirical works by the Kumyk poet Y. Kazak and the Lezgin poet E. Emin. The aim of the article is to show that due to the poetic tradition coming from the depths of centuries, the lyrics of Y. Kazak and E. Emin expanded genre and stylistic boundaries of Dagestani literature. The novelty of the study lies in the fact that for the first time the authors of the article consider the role of the classics of Kumyk and Lezgin literature in the development of the satire genre as the most important direction in the genesis of Dagestani fiction.
Japan's "Big Lie": The Negation of Oral Testimony of Sexual Violence
Authors:   Ritsumeikan University, Kyoto, Japan, O'Mochain Robert , Ueno Yuki ,   Institut National des Langues et  Civilisations Orientales, Paris, France
Published: August 2024

In recent years, powerful actors in Japan’s political elite have consistently denied the oral testimony of so-called “comfort women.” The denial of this and related historical crimes is made in the service of a claim we denote here as the “big lie.” This is the erroneous assertion that the Asia-Pacific War was a straightforward war of liberation by the Japanese Imperial Army, inspired by a blameless Emperor and carried out by morally exemplary military forces. This denial of historical realities, especially those related to “comfort women,” has constituted a contributory factor for a pattern of denial regarding all historical crimes. Effects have been far-reaching, including for survivors of sexual abuse who pursue justice. The determination to deny the validity of oral testimony by “comfort women” carried over into the judiciary and society so that numerous public conversations have created a chilling effect for survivors of abuse. Survey research with 800 young Japanese indicated that invocation of “comfort women” issues and the trope of the selfish “bad girl” led to a diminution in support for victims of sexual abuse and an increased tendency to maintain the status quo of inegalitarian gender relations. Further research is required to determine the extent and the nature of the chilling effect that is engendered by the “big lie” to the detriment of sexual abuse survivors in Japan.

"I första numret av Högre utbildning 2024 är det ett ord som sticker ut eller finns underförstått i flera av de publicerade bidragen, nämligen begreppet reflektion. Reflektion handlar i sin enklaste form om att skapa möjligheter att tänka över sitt lärande, sina framsteg och de många utmaningar som finns i studierna. Men reflektion som begrepp kan vara svårfångat eftersom varje disciplin använder det på olika sätt och därmed definierar det olika."

Indonesia was one of the countries affected by the COVID-19 pandemic. This condition encourages the implementation of various policies, including online learning for students to prevent the spread of the virus. Unfortunately, students have difficulties with this learning system. Therefore, this research aims to analyze the condition factors that support learning performance for university students in Indonesia, namely Task-Technology Fit (TTF), Technology-Induced Engagement (TIE), and Technology-Induced Motivation (TIM). Demographic factors, such as location and gender, were also considered in the analysis. Learning success is assessed from the student's Grade Point Average (GPA) during one semester of online lectures. Data collection was carried out using an online questionnaire strategy, which succeeded in reaching 40 valid respondents. The fuzzyset Qualitative Comparative Analysis (fsQCA) method was used to analyse the configuration model for student online learning success. This research succeeded in formulating six combinations of factor conditions that were sufficient to achieve online learning success. Successful online learning includes whether it was related to gender or not, as well as the location of the student's home, and a combination of other factors. Three combinations of conditions that must exist in every successful configuration of student online learning in Indonesia are, urban study location, students having a high TIE, and also a high TIM. The results of this study contribute to lecturers and higher education management regarding the conditions that need to be prepared to support the success of students' online learning.

The cosmetics industry necessitates efficient inventory management to balance customer demand with stock control. This case study explores how Liza Cosmetics Shop optimized inventory for Lip Cream Implora 01, a popular product, using data-driven forecasting techniques. Traditional trend-based methods often resulted in inaccurate forecasts. This study proposed implementing the SDLC Waterfall Model to apply two forecasting techniques: Least Squares and Double Moving Average. Historical sales data (April 2021 - June 2022) was analyzed to identify demand patterns, seasonality, and trends. The Least Squares method was chosen for its suitability in capturing stable, linear relationships between sales and time, while the Double Moving Average method catered to data exhibiting both long-term trends and short-term fluctuations. Rigorous testing using white-box and black-box methods ensured the accurate functionality and system behavior of the implemented models. The Mean Absolute Percentage Error (MAPE) determined the method best suited for predicting July 2022 demand. This case study contributes insights into data-driven inventory management in cosmetics, highlighting benefits such as optimized stock levels, reduced costs, and enhanced customer satisfaction through improved demand fulfillment. This studys’ limitations including unforeseen marketing campaigns and economic fluctuations impacting forecasts were acknowledged. Despite these challenges, the study emphasizes the potential of data-driven techniques to optimize inventory management and meet customer demands effectively.

Academia Publishing House and the Publication of Works by Ancient Authors in the USSR in the 1920s - 1930s
Authors: Klyuev Artem I.
Published: August 2024

The article analyzes the process of preparing works of ancient authors for printing by the staff of the Academia publishing house. Relying on the office records in the funds of the Russian State Archive of Literature and Art (F. 629), the author has set himself the task of highlighting the key features of the publishing house's work. In general, the author believes that the choice of texts of works by ancient authors for translation was random, and when editors worked with translators, authors of prefaces, etc., there were serious disagreements caused by the lack of a strictly structured process of organizing publishing activities. In addition, when working on individual manuscripts, disagreements between representatives of the former pre-revolutionary and new Soviet traditions, who had different views on the possibilities of interpreting the texts in question, were clearly evident.

The sculptural knife finial from a burial ground near the village of Rostovka certifies the possibility of the transport use a horse by the population of the West Siberian forest-steppe at the beginning of the II millennium BC. The academics perspective of the proposed study is determined by the problem of reconstructing the probable cultural and historical conditions beginning using the harness horses by the foot hunters-skiers. Two probable scenarios of mastering horse-breeding skills are proposed for the reconstruction of the historical and cultural situation according to archaeological and ethnographic sources. The typological analysis the factual material equally allows the implementation of both scenarios in the conditions of technological competition the Seima-Turbino and Sintashta communities. This competition determined the formation of the original economic structure in the south of Western Siberia at the beginning of the II millennium BC. The close relationship metal-production, transport horse breeding and hunting was its specificity. Specialized horse breeding and a high level of metalworking in the ecosystem of the West Siberian forest-steppe were probably combined within a single economic structure based on seasonal alternation of economic and production technological cycles. The basis of the economic activity of the Seima-Turbino communities was serial standardized metal production (thin-walled casting of tin bronze), which instrumentally provided effective meat and fur hunting. Its determined the South Siberian forest cultural complex formation in a historical perspective.

Published: August 2024

The COVID-19 pandemic in 2019 heralded a downturn in the Thai economy, particularly in the tourism and hospitality sectors which rely heavily on international tourists. To decrease the dependence of international tourists, this research outlined three objectives as 1) explore and classify the high-end domestic tourism market among 77 provinces in Thailand, 2) study the potential and readiness of tourism resources and tourism products to cater to the demand of high-end domestic tourists, and 3) suggest tourism management approaches for domestic high-end tourists after the crisis. Both quantitative and qualitative research methodologies were applied to achieve the research objectives. Income was used to identify and segment high-end domestic tourists living in 77 provinces in Thailand, while a verified questionnaire collected data from 1200 respondents nationwide. Forty-one experts from different tourism-related agencies at local and regional levels were targeted using purposive sampling techniques, and semi-structured interviews were conducted to acquire qualitative data. High-end domestic tourists, classified by monthly income, were segmented into Silver (50,000–70,000 THB), Gold (70,001–90,000 THB), Diamond (91,001–110,000 THB), and Platinum groups (Over 110,001 THB). These high-end domestic tourists shared both similarities and differences in tourism needs, preferences, and behaviors. Sixteen provinces in six domestic regions demonstrated the potential and readiness of tourism resources and products to satisfy the needs, preferences, and behaviors of high-end domestic tourists.
An empirical study on green innovation and ESG information disclosure of listed companies in China
Authors: Zhang Shiqing , Wang Zixuan , Ali Azlan
Published: August 2024

Lately, there is a progressive assimilation of sustainable and green development principles into the collective conscience of individuals. Companies have received considerable attention from all sectors of life when it comes to the environment, society and governance (ESG). This study uses a bidirectional fixed effects model to investigate the influence and the mechanism of green innovation on company ESG information, using a research sample composed of data from the A-share listed companies in China spanning the period from 2011 to 2021. The findings indicated that green innovation exerted a substantial positive influence on ESG information disclosure, and the effect was more substantial, especially in mature and declining companies. Financing constraints and analysts’ attention played a mediating role between green innovation and ESG information disclosure. The results of heterogeneity analysis showed that green innovation played a more significant role in promoting ESG information disclosure among state-owned companies, large-scale companies, manufacturing companies and heavy pollution companies. Furthermore, implementing green development policies had facilitated the reinforcement of the promotion impact of ESG information disclosure through green innovation. Additionally, the instrumental variable method was employed to conduct a robustness test. This study enhances the understanding of the theoretical framework about green innovation and the disclosure of ESG information, and offers valuable insights for advancing the sustainable development of companies.

Authors: Ramm Jennifer , Rahn Antonia , Silberhorn Daniel , Wicke Kai , Wende Gerko , Papantoni Veatriki , Linke Florian , Kühlen Markus , Dahlmann Katrin
Published: August 2024

The aviation sector needs to become climate neutral with net zero emissions by 2050 in order to meet the Fly the Green Deal targets. Hydrogen has been identified as a potential energy source that could help the sector meet these ambitious targets. This study evaluated a new hybrid-electric hydrogen aircraft concept against conventional Jet-A1 and power-to-liquid (PtL) aircraft concepts in terms of economic and environmental impacts. The assessment methods that we adopted were adapted specifically for this purpose. The life cycles of the aircraft were modeled using discrete event simulations, and the results show that the hydrogen concept has similar costs to the conventional PtL concept and double the life-cycle [Formula: see text]-equivalent savings compared to the conventional Jet-A1 concept. As such, the method allows early comparison of different aircraft concepts.
Semi-Intrusive Stochastic Galerkin Finite Element Method for Adjoint-Based Optimization Under Uncertainty
Authors: Boopathy Komahan , Kennedy Graeme J.
Published: August 2024

The stochastic Galerkin method for the propagation of probabilistically modeled uncertainties can be difficult to apply in practice due to its formulation and the challenge of creating a computational infrastructure to support it. To address these challenges, this work proposes a sampling-based stochastic Galerkin method that leverages existing deterministic analysis and adjoint-based derivative implementations. The proposed formulation is semi-intrusive since it is implemented using an existing deterministic framework, requiring only the numerical sampling of the deterministic residuals, Jacobians, boundary conditions, and adjoint implementations at nodes in the probabilistic domain. The software architectures to support stochastic generalizations of the deterministic finite element frameworks are presented. This proposed approach is demonstrated using a finite element framework for flexible multibody dynamics problems. Finally, the semi-intrusive implementation of the stochastic Galerkin method is used to demonstrate gradient-based optimizations of flexible multibody dynamics systems in the presence of probabilistically modeled uncertainties.
Validated Dynamic Stall Simulation of Pitching Low Reynolds Number Airfoils
Authors: Zilstra Alison , Johnson David A.
Published: August 2024

Deep dynamic stall is one of several complex behaviors that result in extreme variation of the aerodynamic loads on small wind turbine (SWT) blades during unsteady wind conditions. In this study, unsteady Reynolds-averaged Navier–Stokes simulations are performed for two low Reynolds number (Re) airfoils where sinusoidal pitching is applied to replicate the dynamic stall that occurs on rotating SWT blades. The SD 7037 airfoil is simulated at [Formula: see text] and a pitching reduced frequency of [Formula: see text], and the S833 airfoil is at [Formula: see text] and [Formula: see text]. The simulated lift coefficient and dynamic stall timing agree with experimental data, which is attributed to the wall-normal resolution of the mesh and is an advancement from the early prediction of stall seen consistently in previous numerical studies. The accurate prediction of dynamic stall is found to be dependent on the correct simulation of the bursting of the laminar separation bubble (LSB), which initiates the complete separation of the boundary layer and the formation of a leading-edge vortex. The [Formula: see text] [Formula: see text] model combined with the use of a fine mesh at the airfoil leading edge results in an accurate simulation of the bursting LSB and the correct prediction of the deep dynamic stall.
Enhanced Multimodal Nonparametric Probabilistic Method for Model-Form Uncertainty Quantification and Digital Twinning
Authors: Azzi Marie Jose , Farhat Charbel
Published: August 2024

The nonparametric probabilistic method (NPM) is a physics-based machine learning approach for model-form (MF) uncertainty quantification (UQ), model updating, and digital twinning. It extracts from reference data information not captured by a real-time computational model and infuses it into a “hyperparameterized,” stochastic version of this model by solving an inverse statistical problem formulated using a loss function and a few hyperparameters. The loss function is designed such that the mean value and statistical fluctuations of some quantities of interest predicted using the real-time stochastic model match target values obtained from the reference data. NPM’s performance hinges upon the efficient minimization of the loss function, which is unfortunately stochastic and nonconvex and thus prone to getting the optimization procedure trapped in suboptimal local minima. The latter scenario is exacerbated when the reference data is scarce. The paper addresses these issues by adopting the squared quadratic Wasserstein distance as the measure of dissimilarity between two different sets of data and by reformulating NPM’s inverse statistical problem as a multimodal data-assimilation problem. The potential of the resulting enhanced NPM for MF-UQ, model updating, and digital twinning is demonstrated using numerical simulations relevant to applications in structural dynamics, including structural health monitoring.

Acute benign myositis of childhood (ABIM) is an inflammatory pathology of the musculoskeletal system, it usually manifests with pain in the lower limbs associated with elevation of creatine phosphokinase (CPK). It is a rare condition, but if it occurs, it appears after a flu case, frequently associated with influenza A and B viruses. The case of a school-age girl with myalgia in lower limbs, fever and elevated CPK, diagnosed with MABI, with positive IgG to Bartonella henselae. It is considered important to report the case due to the little information available about this disease both in the country and in Latin America, in addition, to review the issue since there are no previous reports in Peru about Bartonella henselae as the etiological agent of MABI; Likewise, discuss management and how to reduce unnecessary hospitalizations.

В настоящее время захоронение высокоактивных радиоактивных отходов (ВАО) планируется осуществлять в стеклоподобной матрице. Перспективным способом получения остеклованных ВАО является осуществление процесса в индукционных печах с водоохлаждаемыми тиглями (ИПХТ). Цель статьи – представление результатов по разработке графического подхода для обоснования безопасных условий эксплуатации ИПХТ применительно к осуществлению процесса остекловывания ВАО, который базируется на установлении факторов, приводящих к нарушению нормальной эксплуатации ИПХТ, и представлении на совмещенной диаграмме зависимостей между параметрами, важными для безопасности. Проведен анализ совокупности потенциально возможных нарушений нормальной эксплуатации ИПХТ. Предложена схема траекторий постулируемых аварийных событий. Предложены обобщенные диаграммы зависимостей между параметрами осуществления процесса остекловывания ВАО в ИПХТ: температурой расплава стекла, мощностью индуктора, расходом и температурой охлаждающей воды, давлением на напорном трубопроводе, внутренним диаметром трубок тигля. Проведен анализ предлагаемых обобщенных диаграмм, и приведена методология определения с их помощью диапазонов изменения контролируемых параметров для обеспечения нормальной эксплуатации ИПХТ и для обоснования эксплуатационных пределов и пределов безопасной эксплуатации установок по остекловыванию ВАО в ИПХТ.

Currently, a high-level waste (HLW) is being planned to be disposеd in a glass matrix. A promising HLW vitrifying method is melting in cold crucible. The purpose of the article is to present a developed graphical approach to justify the safe operational conditions of the HLW vitrification in cold crucible, which is based on the identification of factors leading to disruption of the normal operation. Also the purpose is to represent the dependencies between the parameters important for safety in the combined diagram. The analysis of the possible failures of the normal operation of the cold crucible is carried out. A scheme of trajectories of the failures is proposed. Generalized diagrams of the dependencies between the parameters of the HLW vitrification process in the cold crucible are proposed: the melted matrix temperature, the inductor power, the flow rate and the temperature of the cooling water, the operating pressure in the feeding pipeline and the inner diameter of the crucible pipes. The methodology based on the carried out analysis of the proposed generalized diagrams is presented for determining the deviation ranges of the governing parameters to ensure the normal operation of the cold crucible and to justify the operational limits and conditions of the HLW vitrification in the cold crucible.

Оптимизация затрат при временном хранении упаковок радиоактивных отходов (РАО) может быть достигнута за счет применения легких хранилищ ангарного типа. Филиалом АО «Концерн Росэнергоатом» «Нововоронежская АЭС» разработана технология кондиционирования РАО в виде солевого плава установок глубокого упаривания в первичных упаковках (стальных цилиндрических контейнерах) путем размещения в дополнительную упаковку – железобетонный невозвратный защитный контейнер. При формировании упаковок применяется способ асимметричной загрузки, обеспечивающий минимизацию гамма-фона от двух боковых граней контейнера за счет формирования резко асимметричной диаграммы направленности гамма-излучения. Разработаны и успешно апробированы эмпирические зависимости для оценки радиационной обстановки на местности при временном хранении РАО в ангарах. На основе метода Монте-Карло разработано специализированное программное обеспечение для прогнозирования изменений радиационной обстановки на местности при перестановках упаковок РАО и принятия решений о возможности размещения контейнеров в периферийных рядах хранилища.

Optimization of costs during temporary storage of radioactive waste (RW) packages can be achieved through the use of light hangar-type storage facilities. Novovoronezh NPP, a branch of Rosenergoatom Concern JSC, has developed a technology for conditioning RW materials in the form of a salt monolith of deep evaporation installations in primary packages (steel cylindrical containers) by placing them in an additional package – a non-returnable protective container. When forming packages, an asymmetric loading method is used, which minimizes the gamma background from the two side faces of the container due to the formation of a sharply asymmetric gamma radiation pattern. Empirical dependences have been developed and successfully tested to assess the radiation situation on the ground during temporary storage of RW in hangars. On the basis of the Monte Carlo method specialized software has been developed to predict changes in the radiation situation on the ground when rearranging RW packages and making decisions about the possibility of placing containers in the peripheral rows of the storage.

«Общие положения обеспечения безопасности атомных станций» (НП-001-15) содержат новое нормативное требование о необходимости принятия в проекте атомной станции (АС) мер, направленных на исключение порогового эффекта. В настоящей статье анализируется (с привлечением как российских, так и авторитетных международных источников) содержание используемого в данном требовании понятия «пороговый эффект». Показано, что к проявлению порогового эффекта следует относить ситуации, когда небольшое изменение параметра АС приводит к потере эффективности двух и более уровней глубокоэшелонированной защиты или к значительному изменению величины радиационного воздействия на персонал, население и окружающую среду, либо к ситуации, когда значимо возрастает вероятность таких последствий. Рассмотрены трактовки понятий «существенное ухудшение безопасности», «параметр», «небольшое изменение параметра», «скачкообразность», использованных в НП-001-15 при определении термина «пороговый эффект». По результатам анализа для последующей дискуссии в среде специалистов предложена матрица определения необходимости принятия в проекте АС мер, направленных на исключение пороговых эффектов, а также определения категории важности в принятии таких мер.

The document “General Provisions for Ensuring Safety of Nuclear Power Plants” (NP-001-15) contains a new regulatory requirement on necessity to provide measures in nuclear power plant (NPP) design aimed at eliminating the cliff-edge effect. The article analyzes (with involvement of both Russian and credible international sources) the content of the concept of “cliff-edge effect” used in this requirement. It is shown that the manifestation of the cliff-edge effect should include situations when a small change in the NPP parameter leads to a loss of effectiveness of two or more levels of defence-in-depth or to a significant change in the magnitude of radiation exposure to personnel, the population, and the environment, or to a situation where the probability of such consequences significantly increases. The interpretations of the concepts of “significant deterioration in safety”, “parameter”, “small change in parameter”, “discontinuity” used in NP-001-15 when defining the term “cliff-edge effect” are considered. Based on the results of the analysis, for subsequent discussion among specialists, a matrix is proposed for determining the necessity of taking measures in NPP design aimed at cliff-edge effect exclusion.
