Authors:   Herzen State Pedagogical University of Russia, Yakovlev Aleksey V. , Puyu Yulia V. ,   Herzen State Pedagogical University of Russia
Published: December 2024

The article examines the philosophical and social meanings of the representation of state symbols. State symbols are aimed at the formation of identification civil determinants based on historical and spiritual values having cultural and civilizational, psychologically deterministic and ideologically formative social dimensions. Within the framework of the socio-philosophical analysis, the cultural, religious, and ideological factors of the meaning formation of state symbols, addressed to the connection between government and civil society, were considered. The state, as a guarantee of the orderliness, stability and security of public relations, significant for citizens as a single community, correlates in symbolic meanings with the individual values of individual life through such conceptual forms as “homeland”, “patriotism”, “citizenship”. As examples confirming the importance of symbolic meanings in the specified aspects, some historical and modern events that influenced civic identification processes are given.

Authors:   Ivanovo State University, Zhulkov Mikhail V.
Published: December 2024

The subject of the study is the safety and methods of protecting individual consciousness in conditions of psychoenergetic information influences. The relevance is determined by the increasing pressure on personal consciousness with the use of information and programming technologies. This goal is solved by the method of philosophical consideration of the phenomenon, structure, dynamics of self-awareness, as well as identification of the sequence of psychoenergetic informational influence. The novelty is determined by the consideration of the problem at the philosophical and psychological level. The theoretical significance lies in a certain contribution to the study of the problem of psychoenergetic information security of individual consciousness, practical – in practical recommendations on psychological, psychoenergetic, information protection of individual consciousness. As a result, it is argued that information and psychological protection consists in strengthening and developing self-awareness through the accumulation and use of mental energy, the development of thinking, reflection, the use of mental protection techniques: receiving information and psychological assistance in specialized institutions, from a friend who is not subject to influence (an outside perspective), via the Internet; dissemination of knowledge about the types of impacts and ways to protect consciousness.

The article analyzes discursive markers used by Russian governors to shape their digital image in social media. The authors examine how political leaders use social media to construct public opinion, enhance trust, and manage their image in the context of modern digital challenges. The study covers the content of Telegram channels of eight governors representing regions with a medium response level for June 2023. The authors highlight key discursive topics (patriotism, socio-economic aspects, interaction with citizens), analyze their frequency and usage patterns. The data obtained demonstrate significant differences in governors’ strategies. Some focus on youth policy and social stability, while others focus on the regions’ economic achievements or maintaining patriotic sentiment. At the same time, the importance of social responsibility, transparency, and interaction with the population in the digital environment is emphasized.

Authors:   Surgut State University, Markhinin Vasily V. , Purtova Victoria S. ,   Surgut State University, Ushakova Nadezda V. ,   Surgut State University
Published: December 2024

The article is devoted to the issue of operationalization of the ideology concepts as a variable in empirical researches. The range of issues in modern studies of ideology at the level of empirical observations is quite diverse: from the ideological attitudes of political activists and organizations, to psychological and genetic factors influencing individual choice in favor of any ideology. However, according to the authors, this kind of researches lack methodological coherence, since the set of indicators for interpreting ideology is often determined arbitrarily. There is a need to develop an operational concept of ideology, reflecting its key functions at different levels of existence in society: theoretical in the form of doctrines, political programs level in the activities of political leaders and organizations, as well as at the level of everyday views of individuals. Thus, the authors strive to identify the place of ideology in the system of political ideas and ideas about politics, to highlight the structural elements of ideology and their relationships in the context of various types of social practice for the subsequent development of an analytical model that allows analyzing ideological constructs both at the level of theory and at the level of individuals’ perceptions.

Published: December 2024

During property renovations, sustainability is increasingly playing a crucial role in reducing environmental impacts, utilizing resources efficiently, and improving the quality of living environments. In our research, we examined the environmentally conscious thinking of potential clients for sustainable renovations, including their requirements for materials, which encompass enhancing energy efficiency, the importance of waste reduction, the significance of using alternative energy, and the application of eco-friendly, durable, and local materials. According to the results of our quantitative survey, respondents recognized the importance of sustainability considerations and expressed their commitment towards energy-efficient and eco-friendly solutions, although costs and payback periods continued to be decisive factors. We found that advocates of sustainable property renovations in our sample displayed environmentally conscious characteristics, and environmentally conscious consumers are willing to spend more for significant and long-term results. As part of our research, we conducted in-depth interviews with real estate agents and general contractors to understand sustainability considerations in the decision-making process of property renovations. The key lesson from the interviews was that buyers can be segmented into different groups, with those prioritizing environmental awareness being of significant importance. Based on the findings, sustainability is increasingly coming to the forefront in property renovations. Thus, our publication offers a detailed insight into market trends and practices.

Authors: Acosta-Minoli Cesar A. A , Mesa-Mazo Monica J. , Cardona-Hernandez Leidy C. , Quintana-Urrea Leonardo I.
Published: December 2024

This study explores the feminization of poverty and the dynamics of the care economy in rural areas, focusing on the municipality of Génova, Quindío, Colombia. The novelty of this study lies in its analysis of the compounded effects of the COVID-19 pandemic on women’s economic participation and care responsibilities in a rural context, offering insights relevant to Latin America. This study addresses the critical problem of how increased caregiving responsibilities and labor informality during the pandemic have disproportionately impacted economically active women, exacerbating gender inequalities. The objective is to analyze the relationship between the care economy and feminization of poverty, providing policy recommendations for post-pandemic recovery in rural settings. The methodology consisted of a two-stage approach. In the first stage, a probabilistic stratified sampling design was applied using data from the Colombian National Population and Housing Census and the Génova, Quindío, and Colombia Municipal Panel. In the second stage, fieldwork was conducted with a sample of 347 women using the RedCap application for data collection. The results indicate a significant increase in unpaid domestic and caregiving work during the pandemic, particularly for the elderly, disabled, and children. Additionally, labor informality increased, further limiting economic opportunities for women. The key conclusion is that public policies aimed at reducing gender disparities in rural labor markets must prioritize caregiving support and formal employment opportunities for women. These findings suggest that addressing the care economy is crucial for closing gender gaps and fostering equitable economic recovery in rural Latin American areas.

Authors: Digdowiseiso Kumba
Published: December 2024

Fiscal decentralization is one of the policy implementations of regional autonomy, which authorizes local governments to manage their local finances independently. However, with the evolution of the times and the dynamics that are taking place, the application of fiscal decentralization worldwide is changing at each time of year. Therefore, it is necessary to investigate fiscal decentralization research temporarily over the course of four decades. The study aims to explain the development of research on fiscal decentralization over a period of four decades. This research integrates Scopus database to offer a thorough conceptual and structural overview of the field by integrating bibliometric approaches and content analysis. The research procedure begins with the determination of the scope of the research, the inclusion and exclusion criteria for the selection process, the collection of data on Publish or Perish (PoP), and the execution of bibliometric analysis on VosViewer. The research shows that the type of journal with the highest productivity has sub-topics of economy, public service, development, and environmental. The development of fiscal decentralization research has a positive upward trend and most of the top-ranked journals indicate that fiscal decentralization has links and influences with other variables. It is apparent that the most often keywords emerged and studied in the research on fiscal decentralization are related to efficiency, measure, role, degree, growth, and fiscal federalism. Meanwhile, the least frequent keywords are related to poverty and inequality, health outcome, environmental pollution, Latin America, South Africa, fiscal autonomy, corruption, OECD country, determinant, and public sector. These keywords are the future lines of research that may be used for future research on the topic of fiscal decentralization.

Published: December 2024

This research aims to identify the development of research theme trends that were carried out from 1999 to 2024. Thus, the study’s results can provide recommendations regarding research themes that can be developed to meet theoretical and practical needs. Researchers use bibliometric analysis to obtain the appropriate analysis. This analysis method can be developed to support the dynamic development of public health science with settings and researchers from developing countries, both through quantitative and qualitative interpretation. The analysis results show that over 25 years, public health science, from the perspective of researchers and developing countries, has experienced dynamic development. This change was driven by the emergence of various issues in society itself. For example, the 1999–2009 shows that lifestyle changes have resulted in multiple diseases. In the following period, the concept of sustainability emerged, which encouraged awareness of sustainable development and resource scarcity that would affect public health quality. As for the 2020–2024 period, the emergence of Covid 19 changed the previous research paradigm.
Wolves in the Woods: An Ecocritical Analysis of Natural Motifs in Marissa Meyer’s Scarlet 
Authors: Markasović Valentina
Published: December 2024

Marissa Meyer is a popular American author of young adult literature, known for writing retellings of famous fairy tales. One of her best-known works is The Lunar Chronicles (2012-2015), a speculative fiction series of which Scarlet (2013) is the second instalment. The novel is loosely based on “Little Red Riding Hood”, centring on Scarlet Benoit and her endeavour to save her kidnapped grandmother. To do so, she joins forces with Ze’ev Kesley, nicknamed “Wolf”, and must leave her grandmother’s farm and travel to the city (the futuristic Paris). Meyerʼs protagonist is an active heroine, an agent in her own journey, while the places she travels through and animals she encounters are not typical, fairy tale topoi serving only as metaphors for human concerns. Instead, they are represented as having innate value, inviting an ecocritical reading. In addition, the novel comments on ecological issues and paints a sharp contrast between the countryside and the cityscape. The article presents an ecocritical analysis of the motifs of the forest and the wolf in Scarlet, tracing their transformation from the traditional versions of “Little Red Riding Hood”. It also explores Meyer’s representation of the future Earth and follows Scarlet’s journey to show how the city has become the main locus of danger, with the text promoting a stronger link between humans and nature.

The relevance of the study is determined by modern economic conditions, in which strategic management accounting is a unique management tool that allows not only to meet the growing needs of company management, but also to form short-term and long-term management decisions that take into account both internal and constantly changing external factors of the economic environment. The objectives of the study are to identify the directions of organizing strategic management accounting, the possibilities of its application in the business activities of an economic entity, based on the professional judgment of a specialist in the field of accounting. The work used general scientific principles and research methods: induction and deduction, systems approach, observation, analysis and synthesis, classification, modeling. In the course of the work, the theoretical aspects of strategic management accounting in world and domestic practice were systematized. An analysis of the views of various authors and a study of the historical context allowed us to conclude that the emergence of ideas of strategic management accounting was the result of the complex impact of many internal and external environmental factors. Systematization of theoretical provisions and proposed modern methods of setting up strategic management accounting allowed us to identify two key aspects that contribute to the successful construction of the entire system of strategic accounting of an economic entity, these are: monitoring and analysis of the external and internal environment, and an integrated approach to implementation. As a result of the study, an algorithm for the construction and implementation of strategic management accounting was developed based on the professional judgment of a specialist. The scientific novelty of the study lies in the development of a classification of prerequisites for the formation of a strategic approach in the activities of economic entities; the formation of a terminological matrix of the concept of «strategic management accounting»; development of the author’s five-step algorithm for constructing and implementing a system of strategic management of an economic entity; highlighting the characteristic features and areas of application of professional judgment in strategic management accounting. The results obtained in the course of the study have theoretical and applied significance and can be used as a basis for the preparation and implementation of strategic management accounting in economic entities. The direction of further research is a set of issues related to the development and implementation of strategic management accounting and its individual elements in the business processes of an economic entity in various sectors of the economy.

The purpose of socio-economic policy at any level is to improve the standard and quality of the population life, which is possible with the maximum implementation of the existing territory’s potential. There are many approaches at modern science to both defining the concept of the territory’s potential (municipality, region, state) and its assessment. A lot of researches are about the innovation, investment, economic potential of regions, but there isn’t assessment of the impact of territories’ spatial development on their potential, which determined the interest in conducting the study presented in the article. The purpose of the study was to develop a methodology for assessing the potential of a region, based on the impact of spatial development of the analyzed territory in the previous period of time. The purpose was achieved by solving a number of problems, such as disclosing the content of the territory’s potential concept, determining the constituent elements of the region’s potential structure, formalizing the approach to assessing the potential of the territory, analyzing the potential of 13 Volga regions, based on the influence of the correction coefficient of spatial development.

The research methodology included the use of the following scientific methods: content analysis, formalization, statistical analysis, comparative analysis. The information base of the research was made up of data from the Federal State Statistics Service (Rosstat).

There is an assessment of the potentials of 13 subjects of the Russian Federation located on the Volga River as a result of the conducted study, which based on the influence of the spatial development of these territories in previous periods of time – 15 and 30 years.

Authors: Gajiwala Uday , Shroff Uma , Naik Nilesh
Published: December 2024

Objectives:

Cataract surgery is a prevalent procedure for restoring vision in patients with cataracts. Intraocular lens (IOL) material selection significantly impacts outcomes. This study aimed to assess the safety and efficacy of poly(methyl methacrylate) (PMMA), hydrophilic, and hydrophobic IOLs in cataract surgery. The primary objective was to assess intraoperative safety and IOL performance. The secondary objective was to determine lens-related adverse events and visual acuity.

Materials and Methods:

This prospective clinical study included adult cataract patients undergoing IOL implantation at a single centre in India. Exclusion criteria included patients unwilling to participate, with previous intraocular or corneal surgery, traumatic cataract, pregnancy or lactation, concurrent participation in other drug or device investigations, unstable keratometry or biometry measurements, or irregular astigmatism. Patients with glaucoma and retinal disorders were also excluded. The study duration was one year with five follow-up visits. For the PMMA, hydrophilic, or hydrophobic IOLs 331, 340 and 330 eyes from 331, 340 and 330 patients were included respectively for the study. Intraoperative safety and performance were assessed through documented adverse events. Visual outcomes were evaluated at each visit using visual acuity measurements, slit-lamp examination, and intraocular pressure measurement.

Results:

No significant intraoperative complications or safety concerns were reported. There were no observed cases of IOL decentration, tilt, dislocation, discoloration, or opacity. Both distance uncorrected and distance best-corrected visual acuity (BCVA) showed significant improvement from baseline to the final visit in all groups.

Conclusion:

PMMA, hydrophilic, and hydrophobic IOLs demonstrated good safety and efficacy in cataract surgery, with significant improvement in visual acuity and no lens-related adverse events reported in this study.
Waste-to-Taste: Transforming Wet Byproducts of the Food Industry into New Nutritious Foods
Authors: Koptelova Anna , Ducrey Aurélien , Lunven Bénédicte , Köller Léa , Nagornova Natalia , Appenzeller Edouard W. , Abitbol Tiffany
Published: December 2024

Food and beverage production generates enormous amounts of spent residues in the form of pomaces, pulps, grains, skins, seeds, etc. Although these sidestreams remain nutritious, their conversion to foods can be complicated by issues of digestibility and processing, particularly when the residues are wet and therefore highly susceptible to microbial degradation. Ideally, these sidestreams could be stabilized and then re-circulated into food, instead of being diverted to waste, animal feed, or biofuels. Indeed, the end-of-life of our food crops is increasingly important to consider in the context of circularity, ensuring that land, water, and chemical inputs to agriculture are sustainable. In the context of wet byproducts from the food industry, we discuss two separate case studies that look at how to valorize and extend the longevity of nutritionally-rich but underutilized sidestreams. The first study examines the fermentation of okara into an edible tempeh-like cake, while the second investigates ProSeed’s approach to drying and valorizing brewer’s spent grain. We conclude with some words on the nuance and challenges involved in saving from waste the highly perishable but nutritious side products of current food and beverage production.
The Changing Landscape of Materials Discovery
Authors: Von Rohr Fabian O.
Published: December 2024

In this perspective, we will discuss the impact of some of the most recent advancements in materials discovery, particularly focusing on the role of robotics, artificial intelligence, and self-driving laboratories, as well as their implications for the Swiss research landscape. While it seems timely to aim for broad, revolutionary breakthroughs in this field, we argue that more incremental steps – such as, for example, fully automatic grinding of solid powders or fully automated Rietveld refinements – may have a more significant impact on materials discovery, at least in the short run. In the center of these considerations is how small, interdisciplinary groups can drive significant progress by contributing targeted innovations, such as e.g.robotic sample preparation or computational predictions. Additionally, given the large investments that are necessary for future infrastructures in materials discovery, we discuss the potential case for the establishment – in the long run – of a national infrastructure, a Swiss Materials Discovery Lab, to support automated material synthesis and advanced characterization, ultimately accelerating innovation in both academic and industrial settings.

Изучали укоренение, рост и развитие перспективных столовых сортов винограда (Кишмиш лучистый, Августин, Надежда АЗОС, Молдова и Преображение) на этапе введения в культуру in vitro. Проведен анализ эффективности применения на микропобегах винограда, стерилизующих растительный материал растворов, 30%-ная перекись водорода, гипохлорит Na 20%-ный и 0,1%-ный раствор сулемы (HgCl). На всех сортах вариант с экспозицией 10 мин был наиболее эффективным, однако при экспозиции 15 мин на варианте с гипохлоритом Na 20% и 0,1%-ного раствора сулемы (HgCl) побеги получили сильные ожоги и оказались нежизнеспособными. Различия по влиянию стерилизующих растворов по сортам также были существенны, при этом наибольшей инфицированностью отличался сорт Кишмиш Лучистый. В проведенных исследованиях установлено, что экспланты винограда при их клональном микроразмножении, в одинаковых условиях in vitro с одинаковой концентрацией регуляторов роста Циркон и Биосил, развиваются отлично один от другого, в зависимости от индивидуальных сортовых особенностей.

Полученные результаты указывают на неблагоприятное состояние окружающей среды в данных городах. Актуальность. Оценка качества состояния окружающей среды различными методами очень важна в настоящее время, т.к. именно с ее помощью можно выявить степень антропогенного вмешательства в природу. На территории республики, и в частности в городе Владикавказе, с XIX века работали предприятия цветной металлургии, функционировали рудники и обогатительные фабрики полиметаллических руд, активно развивался автомобильный транспорт. Все это сказывается на экосистемах РСО-А. Цель. Изучить степень антропогенного загрязнения среды в РСО-Алания на примере промышленного центра Владикавказа и небольшого города Ардон сельскохозяйственной направленности. Методы исследования. Используется метод флуктуирующей асимметрии морфологии живых организмов. Она основана на учете случайных отклонений от двусторонней симметрии у организмов. В случае с растениями обычно используют листья. Если асимметрия превышает определенные показатели, то она считается детерминированной, т.е. возникшей в результате генетических изменений в организме под влиянием среды. Результаты исследования. Условия окружающей среды в городе Ардон имеют существенные, значительные отклонения от нормы. Условия окружающей среды в городе Владикавказе существенно превышают показатели критического состояния среды.

The results obtained indicate the unfavorable state of the environment in these cities. Relevance. Currently an assessment of the environmental state’s quality by various methods is of great importance since it helps to identify the degree of anthropogenic interference in nature. Non-ferrous metallurgy enterprises, mines and processing plants for polymetallic ores have been operating here since the 19-th. Also road transport has been actively developing. All this affects the ecosystems of the republic. Aim. The aim of the research is to study the degree of anthropogenic pollution of the environment in North Ossetia-Alania on the example of the industrial center of Vladikavkaz and the small agricultural city of Ardon. Methods of the study. The method of fluctuating asymmetry of living organisms morphology is used. It is based on random deviations from bilateral symmetry in organisms. Leaves are usually used when studying the plants. If the asymmetry exceeds certain indicators it is considered deterministic, i.e. resulting from genetic changes in the body under the influence of the environment. Results of the research. Environmental conditions in the city of Ardon have significant deviations from the norm. Environmental conditions in the city of Vladikavkaz significantly exceed the indicators of the critical environmental state.

Современная система газо- и нефтеснабжения Российской Федерации представля- ет собой широко развитую магистральную сеть трубопроводов, длины которых достигают тысяч километров. Интенсивная эксплуатация способствует повышению износа системы. Наиболее уязвимыми элементами линейной части трубопроводов являются подводные переходы, поэтому особенно актуальной является задача геодезического обеспечения мониторинга их технического состояния. Цель работы – дополнение методик измерений и обработки данных при использо- вании комплексов картографирования акваторий и трубопроводов с целью повышения точности определения глубин залегания трубопровода. Методы исследования – применение совре- менных информационных технологий в области обработки измерений, математический анализ и расчет повышения избыточности измерений, независимая обработка данных с последующей интерполяцией. Результаты работы и обсуждение – дополнения к методике производства ра- бот и способу обработки данных приводят к увеличению точности измерений путем уменьшения влияния случайных и систематических погрешностей, в том числе приборных, а также к допол- нительной контролируемости. Разработана программа, способная автоматически обрабатывать данные без участия пользователя. Высокая скорость вычислений и отсутствие ошибок, связан- ных с человеческим фактором, позволяют реализовать предлагаемую методику обработки эф- фективнее и надежнее.

Relevance – the modern gas and oil supply system in the Russian Federation is a widely developed main pipeline network, the lengths of which reach thousands of kilometers, which increases the wear of the system, therefore, today, the task of geodetic monitoring of the technical condition of underwater crossings, as the most vulnerable elements of the linear part of pipelines, is particularly relevant. The purpose of the work is to supplement the methods of measurement and data processing when using complexes for mapping water areas and pipelines in order to increase the accuracy of the depths of the pipeline. The research methods are the use of modern information technologies in the field of measurement processing, mathematical analysis and calculation of increasing the redundancy of measurements, independent data processing with interpolation and obtaining data on the depths of occurrence in the same places of the pipeline section. Results of the work and discussion – additions to the methodology of work and the method of data processing lead to an increase in the accuracy of measurements by reducing the influence of random and systematic errors, including instrument errors, as well as additional controllability. As a result, a program has been developed that can automatically process data without user involvement. High processing speed and the absence of errors related to the human factor make it possible to perform the proposed processing method more efficiently and reliably.

The relevance of the study is due to the energy-efficient strategy for the development of the heat power industry and consists in the qualitative improvement of regulatory systems in the field of heat distribution. The purpose of the work is to substantiate the need to take into account the thermal inertia of enclosing structures in the process of local regulation of heat supply to consumers to increase their energy efficiency and to develop an optimal method of local regulation. The research methods include instrumental methods for measuring and controlling thermophysical parameters, a method of mathematical modeling, and methods for comparing and analyzing the results obtained. The results of the work. A study of the influence of temperature regime parameters on the quality of heat supply was carried out on the example of one of the most energy-intensive objects of the district heating system in Chita during two winter months. During the study, the temperatures of the direct and reverse mains water, as well as the temperature of the indoor air in the premises of the facility were monitored. The analysis of the temperatures measured during the study revealed problems in regulating heat consumption that reduce energy efficiency. Based on the analysis, an optimal control method has been developed taking into account the thermal inertia of enclosing structures. Calculations show that the introduction of this method will reduce the deviations of the internal air temperature from the norm and the heating fee.
