Experimental investigation on the residual strength of concrete under the multi-factor coupling action of chloride penetration, freeze-thaw, and fatigue effect

With the ongoing process of globalization and the rapid expansion of the global economy, the proliferation of coastal constructions and infrastructures has witnessed a notable surge. These structures often encounter a confluence of environmental stressors in practical engineering, including cyclic fatigue loading, chloride salt erosion, and freeze-thaw cycles. These synergistic factors accelerate concrete’s failure, resulting in accelerated deterioration and significantly reduced durability. A comprehensive understanding of the damage characteristics of concrete materials in offshore environments, under the multi-factor coupled action of freeze-thaw phenomena, along with an assessment of their residual strength, is crucial for the development of relevant structural analysis and lifetime prediction models. To address this, twenty-seven dedicated specimens were designed and fabricated for this investigation. They were employed to scrutinize the residual strength of concrete under the combined influences of fatigue, freeze-thaw, and chloride penetration. Nine distinct multi-factor coupling actions were meticulously devised and characterized by different parameters. Following the multi-factor coupling action, tests were conducted to assess the residual flexural and compressive strengths, as well as the chloride ion content near the specimen edges. The findings revealed a substantial negative correlation between the residual flexural and compressive strengths with both the number of freeze-thaw cycles and fatigue loading iterations. In contrast, chloride ion concentration and the stress level of fatigue loading (stress ratio: 0.1–0.3) exhibited a comparatively marginal influence. Despite the relatively short test duration, it was evident that both freeze-thaw cycles and fatigue loading exerted a discernible promotional effect on chloride ion ingress in the concrete of the specimens.

Breaking the CO2 Gridlock: Can Renewables Lead the Way for the OECD?

The use of low-carbon energy in power grids is essential for minimizing negative effects on the environment. Energy consumption causes environmental damage to the OECD’s economy. This study aims to investigate the effect of energy consumption, population, and GDP on CO2 emissions using panel data from 17 OECD countries over the period 2000–2023. We use regression approaches, such as partial least squares and principal components, to study the effects of GDP, urban and total population, oil and nuclear use, renewable energy, and industrialization on CO2 emissions. The regression process in this study reduces the data to a two-dimensional representation using a stochastic model and estimation techniques. The findings of this empirical investigation indicate that the United States, Canada, France, Germany, Italy, Korea, Mexico, and the United Kingdom exhibit higher levels of primary energy consumption in comparison to value-added sectors, renewable–geothermal energy, and nuclear energy. We determined the effects of CO2 emissions, GDP, and energy consumption by considering these as the most significant elements. This has made it possible to reduce CO2 emissions by focusing one’s attention and energy on the development of novel technologies, the use of renewable energy sources, and the execution of strategic plans. Attracting increasing attention are technological shifts that deliver enormous quantities of clean energy to combat climate change. Findings from this study can help environmentalists and policymakers better understand the role of structural change and energy consumption processes in the globalization process.

Territorialising knowledge-policy interfaces: Lessons from urban food governance spaces

There has been increased academic attention on enhancing the effectiveness of knowledge-policy interfaces at the international level for urgent food systems transformation. However, previous literature signals that actions to improve science, policy, and society relations occur at multiple scales and often through informal avenues. This paper examines the potential role of multi-actor urban food governance spaces in developing more inclusive and territorialised knowledge-policy interfaces; a subject rarely investigated in the literature. To do so, the study proposes a three-dimensional analytical framework that acknowledges their place-based and networked nature. This framework is applied in València and Barcelona, focusing on the knowledge practices within multi-actor urban food governance spaces and their interrelations with the politics of evidence-informed policymaking. The results illustrate that such spaces function as a form of informal knowledge-policy interfaces that promote local and multi-scalar collective learning and knowledge co-production. However, whether knowledge from such spaces becomes a key part of policymaking grapples with issues of limited administrative capacities, scarce data, and lack of political prioritisation of food in the municipal agenda. As such, there is a need for increased efforts to link global, national, and local processes to build on existing infrastructures at different scales, such as by developing translocal knowledge-policy interfaces. This study not only contributes to progress in the field of food. It also offers insights to enhance science-policy-society relations more broadly, illustrating the need to acknowledge the effectiveness of knowledge-policy interfaces as a function of the broader actings of contested place-based and governance dynamics.

Problems of international politics: impact of globalization on politics

The concept of globalization is associated with the process of expanding crossborder transactions and interactions in the political, socio-cultural, and economic spheres. It describes the phenomenon of denationalization, which tends to be perceived as a political project. Globalization in the international political system is considered centralized due to its impact on external relations and its close connection with political structures and mechanisms. The creation of the necessary international rules and institutions is characterized by the fact that the concept of global governance is a political response to the processes of economic and social globalization. The influence of the era of globalization on the development of international politics and economic structures has turned out to be deep and complex, being the background for the creation of new political forms and stages of its development. The modern process of globalization is focused on international transformations in the field of politics and economics. It is important to emphasize the fact that the concept of globalization is a broad issue that is an integral part of every field of public activity. It can be described as an acceleration of global economic and political interconnections; the analysis of this phenomenon made it possible to assess the problems caused by its development. This article shows the importance of the globalized world for the life of individual states and international cooperation. The large-scale changes caused by globalization have proved its significant role for cultural, social, economic, and political formation at the international level. The research was based on the theory of globalization, the concept of sustainable development, and the theory of competition. Conclusions. The impact of globalization is felt most strongly when it comes to identity, whether it is an individual or a community. Although globalization can have positive effects, this phenomenon needs to be critically assessed in order to ensure that its negative consequences are understood, studied, and effectively addressed.

Geohistorical insights into marine functional connectivity

Abstract Marine functional connectivity (MFC) refers to the flows of organic matter, genes, and energy that are caused by the active and passive movements of marine organisms. Occurring at various temporal and spatial scales, MFC is a dynamic, constantly evolving global ecological process, part of overall ecological connectivity, but with its own distinct and specific patterns. Geological and historical archives of changes in the distributions, life histories, and migration of species can provide baselines for deciphering the long-term trends (decadal to millions of years) and variability of MFC. In this food-for-thought paper, we identify the different types of geohistorical data that can be used to study past MFC. We propose resources that are available for such work. Finally, we offer a roadmap outlining the most appropriate approaches for analysing and interpreting these data, the biases and limitations involved, and what we consider to be the primary themes for future research in this field. Overall, we demonstrate how, despite differences in norms and limitations between disciplines, valuable data on ecological and societal change can be extracted from geological and historical archives, and be used to understand changes of MFC through time.

Efficiency-Oriented Model Predictive Control: A Novel MPC Strategy to Optimize the Global Process Performance.

Existing control strategies, such as Real-time Optimization (RTO), Dynamic Real-time Optimization (DRTO), and Economic Model Predictive Control (EMPC) cannot enable optimal operation and control behavior in an optimal fashion. This work proposes a novel control strategy, named the efficiency-oriented model predictive control (MPC), which can fully realize the potential of the optimization margin to improve the global process performance of the whole system. The ideas of optimization margin and optimization efficiency are first proposed to measure the superiority of the control strategy. Our new efficiency-oriented MPC innovatively uses a nested optimization structure to optimize the optimization margin directly online. To realize the computation, a Periodic Approximation technique is proposed, and an Efficiency-Oriented MPC Type I is constructed based on the Periodic Approximation. In order to alleviate the strict constraint of Efficiency-Oriented MPC Type I, the zone-control-based optimization concept is used to construct an Efficiency-Oriented MPC Type II. These two well-designed efficiency-oriented controllers were compared with other control strategies over a Continuous Stirred Tank Reactor (CSTR) application. The simulation results show that the proposed control strategy can generate superior closed-loop process performance, for example, and the Efficiency-Oriented MPC Type I can obtain 7.11% higher profits than those of other control strategies; the effectiveness of the efficiency-oriented MPC was, thereby, demonstrated.

Research and analysis of urban-rural residential carbon emissions in China

Residential carbon emissions are an important component of anthropogenic carbon emissions. a significant increase in residential carbon emissions has become a reality under the global urbanization process. In this context, this paper built a feature combination value model based on NPP-VIIRS nighttime light remote sensing data, and divided urban-rural areas through breakpoint analysis method and reference comparison method. Then, explored the characteristics and differences of residential carbon emissions and per capita residential carbon emissions in nine different levels of cities in 2019 from the perspective of urban-rural areas. The results indicate that the residential carbon emissions and per capita residential carbon emissions shows the spatial distribution characteristics of first tier cities>second tier cities>third tier cities. Among them, the residential carbon emissions in Beijing, Guangzhou, Nanjing, Taiyuan show a distribution pattern of urban>urban-rural fringe>rural. The residential carbon emissions in Shijiazhuang, Wuxi, Xiangyang, Zunyi, Huai’an show a distribution pattern of rural>urban-rural fringe>urban. The per capita residential carbon emissions of urban areas are relatively low, while the per capita residential carbon emissions of rural areas are relatively high, show a distribution pattern of rural>urban-rural fringe >urban. The results can help the Chinese government balance the needs of urban-rural development in different levels of cities, so as to formulate targeted carbon emission reduction policies and achieve low-carbon goals.

CORRELATION AND REGRESSION ANALYSIS OF THE IMPACT OF ECONOMIC GLOBALIZATION ON THE DEVELOPMENT OF NATIONAL MARKETS

The study of consequential relations between economic globalization and the number of subsidiaries of leading TNCs revealed that their development largely depends on the country's involvement in the globalized space. Correlation analysis confirmed the existence of a relationship between TNCs and GDP, which is the main macroeconomic indicator that reflects the participation of countries in export-import operations. Analysis by industry confirmed that economic globalization contributes to the growth of TNCs through increased GDP, regardless of the type of goods and services. On the contrary, TNCs can also have a positive impact on GDP, supporting the scale of economic globalization. Regression analysis and construction of regression models revealed the specifics of the impact of economic globalization on the development of TNCs in countries with different socio-economic conditions. This specificity consists in differences in the influence of one set of factors on the number of foreign branches of TNCs in countries with different levels of development. This confirms the controversy of the phenomenon of economic globalization and indicates that the growth of TNCs is possible only in countries with high indicators of economic globalization. The development of countries is asymmetric, so the spread of globalization processes is also uneven, which indicates the different response of economies to their influence.

CONTEMPORARY GLOBALIZATION PROCESSES IN THE CONTEXT OF THE DEMOGRAPHIC DIMENSION

Modern processes of globalization and their demographic interpretation are the latest trend of political reality for the states of the modern world. The processes inherent in the world community have really acquired a real global character. For a certain time, the states have been addressing issues in the field of demography and its impact on political reality in a fairly timely manner. At the same time, the researched topic has really raised the question of the effectiveness of governments and the conglomeration of the world community in the face of demographic challenges that have acquired a global character. The authors of the presented article, relying on the research of a wide range of recent and diverse sources and using the methods of scientific research, tried to reveal the essence and mutual influence of globalization processes and demography. The main results and conclusions of this article make a certain contribution to the study and prevention of the latest threats and challenges at the level of sovereign states and their associations for joint prevention of political, social, cultural and other problems. In addition, there is an objective need to conduct a different range of research on the widest range of issues related to globalization and demographic processes, such as population ageing, the growth of the middle class, and the impact of new technologies. In this regard, the authors of the article highlight the relevance of the analyzed data and the situation in the world in the context of prevention of world threats in the globalizing political community.

Eutrophication of Lakes: From Global Process to Regional Implication in the Kola Arctic Region

ABSTRACTEutrophication of water bodies is analysed as a global process. The volumes of globally increasing use of nitrogen and phosphorus are demonstrated, with the dispersion of these elements leading to increased nutrient contents in lakes and rivers. Results of original studies on remote lakes in the Arctic zone indicate that the content of nutrients in these lakes has increased over the past decades. Concentrations of nitrogen, phosphorus and organic matter in lake waters tend to increase in the absence of anthropogenic effects. Simultaneously, the silicon concentrations were found to decrease because of the consumption by diatoms. Low concentrations of bioavailable nutrients confirm that these nutrients are rapidly spent in the production processes of ecosystems. The calculated trophic state index (according to R. Carlson) indicates that the number of oligotrophic lakes in the forest tundra zone decreased by 50% by 2010–2018, and these lakes are absent from the northern taiga zone. Temperature increase and climate warming in the Arctic zone first caused the increase in the contents of nutrients in the lakes and their trophic states.

Predicted community consequences of spatially explicit global change-induced processes on plant-insect networks.

Plant-insect trophic systems should be particularly sensitive to processes altering species spatial co-occurrences, as impacts on one level can cascade effectively through the strong trophic reliance to the other level. Here, we predicted the biogeography of Lepidoptera-plant communities under global-change scenarios, exploiting spatially resolved data on 423 Lepidoptera species and their 848 food plants across the German state of Baden-Württemberg (ca. 36,000 km2). We performed simulations of plant extinction and Lepidoptera expansion, and respectively assessed their cascading consequences-namely secondary extinction of Lepidoptera and change in functional distance of plants-on the interaction networks. Importantly, the simulations were spatially explicit, as we accounted for realistic landscape contexts of both processes: Plant extinctions were simulated as "regional" (a species goes extinct in the whole region at once) vs. "isolation-driven" (a species gradually goes extinct from the peripheral or isolated localities according to its real regional distribution); Lepidoptera expansions were simulated with random, northward, and upward directions according to real topography. The consequences were assessed based on empirical community composition and trophic relationships. When evaluated by regional richness, the robustness of Lepidoptera assemblages against secondary extinctions was higher under isolation-driven plant extinctions than regional plant extinction; however, this relationship was reversed when evaluated by averaged local richness. Also, with isolation-driven plant extinctions, Lepidoptera at the central sub-region of Baden-Württemberg appeared to be especially vulnerable. With Lepidoptera expansions, plants' functional distances in local communities dropped, indicating a possible increase of competition among plants, yet to a lesser extent particularly with upward movements. Together, our results suggested that the communities' composition context at the landscape scale (i.e., how communities, with respective species composition, are arranged within the landscape) matters when assessing global-change influences on interaction systems; spatially explicit consideration of such context can reveal localised consequences that are not necessarily captured via a spatially implicit, regional perspective.

The importance of transportation in the Slovakia-Vietnam business decisions about the importing or exporting of goods

Globalization and geographic fragmentation of global manufacturing processes have characterized the expansion of international trade. As a result, supply chains have grown longer and more complex, making transportation a key factor in business decisions about the export or import of goods. By analysing the export and import of merchandise between Slovakia and Vietnam, this paper aims to determine the best mode of transportation in terms of transport modalities. To put it another way, it uses a case study, LPI index and results of primary research to identify qualitative transport indicators when the companies import or export goods from Vietnam to Slovakia. We also focused on examining the macroeconomics factors - agreements between European Union (Slovakia as a member of the EU) and Vietnam, which affect the international trade.

The role of AI and emerging technologies in global trade compliance

Artificial intelligence (AI) in global trade compliance is evolving rapidly, notably in classification, with the potential to unlock productivity, expand expertise and improve speed, reliability and accuracy. Due to its potential, AI is met with high expectations and sometimes apprehension, as there is a lot of uncertainty about what constitutes AI and how it will affect global trade stakeholders. The aim of this paper is to demonstrate how AI will likely affect customs agencies, importers/exporters, service providers and compliance managers. By using examples and case studies, the paper explains: 1) the role of AI expert systems (ES) that use machine learning (ML) and natural language processing (NLP); 2) AI’s potential and limitations in sourcing compliance knowledge for streamlining and automating global trade compliance activities; 3) the importance of upskilling compliance managers and compliance teams to successfully deploy AI, mitigate risks and better manage the global trade compliance process; and 4) our six steps for successfully implementing AI in your global trade compliance department. You will learn how AI can be valuable in performing your job and meeting your goals, if it is kept within its range of capabilities. By such measures, you will be able to obtain the advantages presented by the use of AI, while mitigating its very present risks, some of which are known and many of which are unknown.

INTERACTIONS OF EDUCATIONAL INSTITUTIONS WITH THE EXTERNAL ENVIRONMENT AND SOCIAL ORGANIZATIONS

Strategic directions of the cluster approach (collaborative activity) of the educational process carried out in educational organizations, means of using the power of the globalization process "against oneself", best practices of foreign countries, external environment of educational institutions and social organizations relationship with, the infrastructure of innovative activity, the characteristics of educational organizations, the innovative management competency of the head of the educational organization.

Gender, Intersectionality, and Global Social History

AbstractOne of the most fruitful concepts of recent social analysis has been that of intersectionality, the idea that the nature of oppression is multiplicative rather than additive, and that no one identity – race, class, gender, religion, ability, sexual orientation, and so on – should be considered apart from other identities, but is always materialized in terms of and by means of them. Although it was developed out of the US experience, intersectional epistemology has been dynamic and mobile, as scholars have not simply used social groupings drawn from the Western past and present but have elaborated social categories taken from local understandings as well. This article analyses some recent examples of gendered world history that also take other social hierarchies into account, and assesses how these help us better understand global processes that transformed societies. It begins with a place and time where global entanglements led quite clearly to the emergence of new social groups, the Spanish and Portuguese colonies in the Americas, and then more briefly examines this process in other parts of the early modern colonial world.

Tutoring as a form of support for the adaptation of foreign students at the university

Introduction. Strengthening globalization processes leads to the expansion of international cooperation in the field of education. This is especially reflected in the growth of international mobility of students in higher education institutions, in particular, Russian universities. And if the first students of the beginning of the large waves of mass educational migration were proficient in the Russian language and were familiar with Russian culture, then the students who followed them were much less proficient in the language and cultural code. And, since the internationalization of education remains a prerequisite for the existence of universities, and long-term adaptation of foreign students to learning conditions worsens the quality of their training, there is a need to organize their psychological and pedagogical support in the first years of study. The purpose of the article: to specify the main problems of adaptation of foreign students to the conditions of study in Russian universities and to justify the need to organize their tutor support. Materials and methods. The study involved 556 international students of the first and second years of study of three Tatarstan universities (Kazan National Research Technological University (KNRTU-KICT), (Kazan); Kazan National Research Technical University named after A. N. Tupolev (KNRTU-KAI), (Kazan); Elabuga Institute of the Kazan (Volga Region) Federal University (EI KFU) (Elabuga). Research results. The results of the study confirmed the presence of adaptation problems among foreign students. The main ones are difficulties with the Russian language (41%) and acclimatization (21%). It takes 46% of students about a year to get used to the learning conditions, and 23% – more than a year. The main learning difficulties they identify are awkwardness when speaking in public in front of an audience (23%) and teachers’ underestimation of their educational results (20%). More than half of the students see older compatriots as a source of help in overcoming cultural and educational barriers; The help of a supervisor turned out to be effective only for 15% of respondents. Taking into account the results obtained, it is proposed to organize the training of future tutors from among foreign senior students who have undergone appropriate psychological and pedagogical training. Conclusion. While maintaining the institute of curatorship, it is necessary to create a tutoring institute in universities that train foreign students. The main functions of tutors, which are absent from the curators of academic groups, should be to help foreign students overcome barriers to socio-cultural adaptation and insufficient proficiency in Russian, promote the acceptance of foreigners by their new environment, help in building effective interaction with the university administration and teachers, study students' personalities, monitor the results of their educational activities, help in professional identification, monitoring of newly emerging difficulties of students, strengthening cooperation between Russian and foreign students.

TRANSFORMATION OF THE EU FOREIGN ECONOMIC POLICY IN THE CONTEMPORARY SCIENTIFIC LITERATURE

The study of the EU’s foreign economic policy is one of the key topics in the modern scientific literature due to the EU’s significant influence on the global economic processes. This article analyzes evolution of the relevant research by Russian and foreign authors, including both modern works and publications of the early 2010s, when this topic began to gain relevance in the context of studying international trade relations. Special attention is paid to the issue of transformation of the EU Commission’s foreign economic policy formulation due to the implementation of the 2021 trade policy strategy, aimed at ensuring «strategic autonomy» of the Union. This article reviews existing discussions regarding the definition of this concept, as well as regarding its main instruments. In conclusion, the author identifies key gaps in respective scientific knowledge and presents directions for further study. It is proposed to investigate the ongoing changes using a paradigmatic research method that is based on the 1993 theory by Peter Hall. A deeper understanding of the EU's trade policy changes will allow Russia to more effectively adapt its behavior in the international arena, as well as its interaction with the other global players.

Main Directions of Modern Transformation and Modernization of Russian Society, Ways to Overcome the Systemic Crisis in the Context of Technological Revolution: Alternative Strategic Development Models

At the present stage of Russia’s development in the prevailing historical conditions, a period of deep conceptual transformations has begun, measures are being taken to free it from its continued dependence on crisis global processes, from the globalism policy of developed imperialist countries. Today, after three periods of permanent systemic crisis, through which Russia went from the early 80s to the early 2000s, the country is emerging from this dependence, returning to its mental ideological and cultural foundations, to state-political, economic, scientific, technical and technological sovereignty, to the status of a world power, renewed civilization, towards the consolidation of society. This period is characterized as a period of transformation and new modernization of society. The article, based on new approaches and methods of a comprehensive historical, sociological and formational-civilizational analysis of the problems of society’s development, examines the issues of the new modernization of society that has begun, analyzes and evaluates the persistent manifestations of the systemic crisis, issues of implementing an innovative anti-crisis management strategy, strategic planning and strategic management. Possible forecasts and alternatives for social development are considered. These processes require a clear, meaningful choice and implementation of a long-term strategy for the dynamic, innovative development of knowledge-intensive sectors of the economy, labor productivity growth, production recovery based on new reindustrialization and the industrial revolution, the development and implementation of achievements of the fifth technological order, scientific, technical, technological, information revolution, the formation of new scientific, human resources, including in the areas of governance of society and the state, ensuring comprehensive security and sovereignty of society and the state, regulatory support for these processes. This implies the choice of a new socio-economic, formational and civilizational model for further progressive development, taking into account positive domestic and foreign experience, and the corresponding ideological basis for these transformations. All this is becoming an urgent issue for the entire spectrum of social and social sciences, for educational practices.

Discrimination of coal geographical origins through HS-GC-IMS assisted with machine learning algorithms in larceny case

The process of globalization and industrialization has resulted in a rise in the theft of coal and other related products, thereby becoming a focal point for forensic science. This situation has engendered an escalated demand for effective detection and monitoring technologies. The precise identification of coal trace evidence presents a challenge with current methods, owing to its minute quantity, fine texture, and intricate composition. In this study, we integrated machine learning with the identification of volatiles to accurately differentiate coal geographical origins through the application of headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS). The topographic distribution of volatiles in coals was visually depicted to elucidate the subtle distinctions through spectra and fingerprint analysis. Additionally, four supervised machine learning algorithms were developed to quantitatively predict the geographical origins of natural coals utilizing the HS-GC-IMS dataset, and these were subsequently compared with unsupervised models. Remarkable volatile compounds were identified through the quantitative analysis and optimal Random Forest model, which offered a rapid readout and achieved an average accuracy of 100 % in coal identification. Our findings indicate that the integration of HS-GC-IMS and machine learning is anticipated to enhance the efficiency and accuracy of coal geographical traceability, thereby providing a foundation for litigation and trials.

INTERDEPENDENCE OF SOCIAL AND POLITICAL CHANGES: RISCOGENIC POTENTIAL

The article considers the risk-generating potential of changes occurring in the subsystems of modern social systems in their interaction with the natural and spiritual environment. The systemic representation of the structure of social systems developed by T. Parsons is used. The risks associated with global processes that conflict with the established approaches to the organization of material production and reproduction of cultural samples are shown. An analysis of the risks associated with the discrepancy between the interests of the groups of the social subsystem formed in the process of functioning of the economic subsystem and the cultural subsystem is given. The functions of the political subsystem to reduce the severity of these risks are revealed, as well as the risks arising in connection with the ineffective performance of these functions by the political system. Conclusions are formulated based on the analysis of modern political processes in Russia and the West. It is shown that there are objective and subjective factors reducing the effectiveness of the performance of the main functions by the subsystems of society, giving rise to significant risks of its destabilization.
