Prospects of organizational and legal provision of energy security of Ukraine in the conditions of modern geopolitical processes

The scientific article is devoted to one of the important objects of national security – energy security. The organizational and legal approaches to the regulation of energy security are singled out and certain aspects of state regulation of energy efficiency are outlined, taking into account modern geopolitical processes. The definition of energy security is formulated, its global nature is indicated, which determines its provision through the joint efforts of all countries of the world, taking into account the internal characteristics and needs of the industry. It was emphasized that energy security as an object of state policy in the conditions of armed aggression against Ukraine requires proper legal regulation and continuous coordinated state management influence in order to ensure the energy independence of the country and the stable operation of energy infrastructure facilities. The analysis of the legal provision of energy security in Ukraine allowed us to come to the conclusion about the ramifications of the legislation in the specified area, the lack of optimization and systematization of energy legislation, its conflict and tolerance for the monopoly position of energy market participants. In the conditions of the war in Ukraine, the main direction of legislative regulation of the energy market is the introduction of tax benefits, temporary special taxation regimes. It was concluded that the introduction of the Institute of the Authorized President of Ukraine on Energy Safety, the development of the Institute of Public Control in the specified field is considered a promising direction for improving the national institutional mechanism for ensuring energy security. Arguments are also given that the institutional and legal mechanisms for ensuring energy security should provide for: permanent strategic planning of the development of the energy sector; coordination of energy policy with other areas of state policy; elimination of illegal administrative influence on energy market participants; taking measures to improve energy efficiency; creation of conditions for the development of technological innovations in the field of functioning of the energy infrastructure; increasing the effectiveness of preventing cyber threats; taking measures to reduce the level of corruption and the influence of the political will of elites on the energy market of Ukraine, state deregulation and demonopolization of the energy resources market.

Legal regulation of economic security in Ukraine

It is indicated in a legal state, regulation of interaction between members of society, coordination of their interests and smoothing of conflicts arising between them and their associations is unthinkable without law. With the help of the influence of law on social relations, it is possible to order and regulate them in a civilized manner. In the sphere of achieving a state of security, the law allows you to set the limits of what is permitted, to determine the obligations and prohibitions in the behavior of the relevant subjects. Due to regulatory legal regulation, security receives a unique meaning that determines the final goal of its provision, connects it with national priorities and interests of each legal entity, preventing blurring of the understanding of the essential characteristics of the basic category «national security» and its derivatives. The conducted scientific analysis of the legal regulation of the economic security system of Ukraine made it possible to conclude that it has a complex and multifaceted nature, that is, it involves the creation of a complex of legal, economic and administrative-organizational mechanisms aimed at ensuring the rights of citizens and other subjects of economic activity to protect private property, economic freedom and unimpeded implementation of economic and other economic activities. It is pointed out that the state should implement the appropriate organizational and legal provision of economic security of Ukraine, aimed at increasing the investment attractiveness of the country, eliminating offenses in the economic sphere. The analysis of regulatory legal acts made it possible to single out the following shortcomings of the legal provision of economic security of Ukraine: complexity, vagueness and inconsistency of individual legislative norms, ambiguous interpretation in their application; inconsistency between developers and lack of system of legal acts regulating economic security. It was concluded that the presence of such shortcomings indicates the need to modify approaches to the formation of legal support for the economic security of the state, to make changes to the current legislation.

Assessing Japan’s Taiwan Policy: Systemic Clarity, Political Survival and Bureaucratic Prudence

ABSTRACT What are the patterns of Japan’s foreign policy behavior toward Taiwan in the post-Cold War era? It is generally taken for granted that the origin of Japan’s foreign policy to Taiwan has been derived from a unitary strategic calculation related to East Asian international politics and its maritime security in the Asia-Pacific region. This conventional interpretation is insufficient. While external pressure and states’ relative material capabilities within the structure of the international system are crucial in explaining Japan’s policy toward Taiwan, interpretations based solely on the system level of analysis fail to provide a persuasive explanation of Japan’s foreign policy behavior. By conducting three case studies in 2006, 2019 and 2021 through the theoretical lens of neoclassical realism and empirical investigation based on primary and secondary Japanese-language sources, this article argues that Japan’s Taiwan policy has been shaped by the combination of three factors: the degree of systemic clarity at the international level, the Japanese prime minister’s political survival and bureaucratic prudence over the Taiwan issue at the domestic level. Since 2021, Japan has adopted a subtle approach to Taiwan, driven more by a defensive and precautionary response to the heightened sense of crisis across the Taiwan Strait.

OFL-W3: A One-Shot Federated Learning System on Web 3.0

Federated Learning (FL) addresses the challenges posed by data silos, which arise from privacy, security regulations, and ownership concerns. Despite these barriers, FL enables these isolated data repositories to participate in collaborative learning without compromising privacy or security. Concurrently, the advancement of blockchain technology and decentralized applications (DApps) within Web 3.0 heralds a new era of transformative possibilities in web development. As such, incorporating FL into Web 3.0 paves the path for overcoming the limitations of data silos through collaborative learning. However, given the transaction speed constraints of core blockchains such as Ethereum (ETH) and the latency in smart contracts, employing one-shot FL, which minimizes client-server interactions in traditional FL to a single exchange, is considered more apt for Web 3.0 environments. This paper presents a practical one-shot FL system for Web 3.0, termed OFL-W3. OFL-W3 capitalizes on blockchain technology by utilizing smart contracts for managing transactions. Meanwhile, OFL-W3 utilizes the Inter-Planetary File System (IPFS) coupled with Flask communication, to facilitate backend server operations to use existing one-shot FL algorithms. With the integration of the incentive mechanism, OFL-W3 showcases an effective implementation of one-shot FL on Web 3.0, offering valuable insights and future directions for AI combined with Web 3.0 studies.

Ecological security assessment of Yunnan Province, China in the context of Production-Living-Ecological space division.

With the rapid development of population, society and economy, human activities have caused serious adverse impacts on the environment, ecosystems and landscape patterns over the long term. In order to address the series of impacts of human activities on the environment, territorial space and resource use, the study of Production-Living-Ecological Space (PLES) and ecological security have all become academic frontiers in the field of sustainable development. In this study, we applied multi-source data and GIS technology to construct an ecological security evaluation model based on the results of PLES delineation and the Pressure-State-Response (PSR)framework, and carried out the three-period PLES ecological security evaluation for 2000, 2010 and 2020 at the county and grid scales in Yunnan Province. The PLES pattern in Yunnan Province is dominated by ecological space, which accounts for 75%, followed by 23% of production space, with ecological space shrinking from 2000 to 2020. Ecological security in ecological space and living space shows an improving trend from 2000 to 2020. The ecological security of production space improved in 2010 compared to 2000 but then showed a decreasing trend in 2020. Ecological security in ecological space shows that north-western and southern Yunnan is safer than central Yunnan, while ecological security in living space is safer in central Yunnan, and ecological security in production space is better in southern Yunnan than in northern Yunnan. Comparison with related research results shows that the ecological security evaluation results of PLES in Yunnan Province in this study are scientific and reasonable. The ecological security evaluation model of PLES constructed in this study solves the problem of complex and incomplete ecological security evaluation indexes in the past, and the results of the study are more refined and precise, which provides new ideas for the study of regional ecological security.

Response of the Northeast China grain market to climate change based on the gravity model approach

Scientific evidence has revealed that climate change negatively affects agricultural crop production both regionally and globally. Previous studies have indicated that the role of climate change is significant in some parts of China. Thus, assessing the impact of the future climate on the grain market is vital for ensuring regional and national food security. In this study, regional climate model (RCM 4.5 and 8.5) simulations were employed to investigate the role of future climate change on a major grain-producing market in China (Northeast China). For this purpose, historical (2004–2017) and future (2020–2076) data were applied in the gravity model to examine the effects of climate change on the Northeast China grain market. The results revealed that the maximum temperature is a crucial climate factor that significantly affects the grain market. The analysis revealed that precipitation was positively related and that the temperature was significantly negatively related to domestic consumption and exports of rice, maize, and soybean. Moreover, the analysis of the RCM (4.5 and 8.5) simulations revealed a negative contribution of the maximum temperature to domestic consumption and export levels. Overall, the analysis enhances our understanding of the impacts of climate change on the Northeast China grain market.

Indo-Pakistan rivalry and integrated ring balancing: prospects and challenges to regional stability in South Asia

ABSTRACT Pakistan's security landscape faces unprecedented challenges due to India's burgeoning power and its strategic alignment with the United States. This study proposes an innovative ‘Integrated Ring Balancing’ framework to navigate this complex geopolitical environment. The framework operates across three tiers: Tier 1: Direct engagement with immediate neighbors – India, Iran, China, and Afghanistan. Tier 2: Building robust linkages with the neighbors of Pakistan's Tier 1 partners, encompassing South Asia, Central Asia, Southeast Asia, and the Middle East. Tier 3: Leveraging major powers – China, Russia, and the United States – through Tier 1 and 2 partnerships. This multi-layered approach aims to achieve two key objectives: (1) Neutralize India's US-backed advantage: Engaging China and Russia can influence Tier 2 states, particularly in Central Asia, to rebalance their regional positioning towards Pakistan. (2) Develop a collective defense system: Converging geo-economic interests via initiatives like the China–Pakistan Economic Corridor (CPEC) and the Belt and Road Initiative (BRI) can foster a regional security ring around Pakistan. By strategically engaging across these tiers, Pakistan can navigate the complex power dynamics in South Asia, bolster its security, and ultimately safeguard its national interests in the face of a strengthened India.

Cross-border regulatory cooperation and cash holdings: Evidence from US-listed foreign firms

We investigate the effect of cross-border regulatory cooperation on the cash holdings of firms cross-listed on US stock exchanges. The staggered adoption of the Multilateral Memorandum of Understanding (MMoU) facilitates cooperation among securities regulators around the world and expands their enforcement capabilities against foreign firms. Using a difference-in-differences design, we find that US-listed foreign firms significantly reduce their cash holdings after their home countries sign the MMoU, suggesting that the threat of increased SEC enforcement induced by regulatory cooperation disciplines corporate insiders from stockpiling cash holdings to enjoy private benefits of control. Information opacity and the cost of capital are two of the channels through which the threat of increased SEC enforcement affects cash holdings. The reduction in cash holdings is more pronounced for foreign firms from countries with weaker governance. After the MMoU, foreign firms make faster cash adjustments toward target levels, they reduce cash by making payouts, and their cash is valued more by investors.

Waters of Contention: The GERD and Its Impact on Nile Basin Cooperation and Conflict

The Grand Ethiopian Renaissance Dam (GERD) on the Nile River has become a focal point in the fields of water diplomacy, economics, and environmental considerations in the Nile Basin. Announced during the Arab Spring in 2011, the GERD aims to address Ethiopia’s significant energy shortfall and foster regional economic growth by potentially doubling the country’s electricity output. However, this ambition has heightened tensions with downstream countries, especially Egypt and Sudan, which rely heavily on the Nile for their water needs. This paper examines the ongoing conflict surrounding the GERD, focusing on the deadlock situation despite considerable scholarly attention to its economic, political, and environmental dimensions. The analysis presented in this paper reveals the roots of contention by analyzing past treaties and the present negotiation status, illustrating the complex interplay between development goals, environmental sustainability, and regional water security. The paper advocates for a revised legal framework that moves beyond past agreements towards a more inclusive, cooperative management strategy for the Nile’s waters. It proposes the development of a new treaty between Egypt, Ethiopia, and Sudan, grounded in their 2015 Declaration of Principles agreement and inspired by successful international dispute resolutions. It also discusses the potential of neutral third-party interventions to facilitate unbiased negotiations grounded in the Graph Model for Conflict Resolution, emphasizing the importance of equitable and sustainable water governance. In essence, this research calls for a collaborative approach to resolve the GERD conflict, emphasizing the need for agreements that harmonize developmental ambitions with the water security of the Nile Basin nations. .

US Military Posture in the Asia-Pacific and its Impact on Regional Stability

The geopolitics of Asia-Pacific are witnessing a transition. The regional powers calculate their bets as China rises as a key player and challenges the traditional dominance of the United States. The region hosts various flashpoints – in the wake of rising tensions, the US and China may redefine the power equilibrium, resulting in increased militarization and altering the region’s security environment. The evolving geopolitical dynamics thus characterize a power rivalry between these two powers. In pursuit of influence and supremacy, the US generates far-reaching consequences for regional stability. The involvement of the US in the region and the interests of regional stakeholders are closely connected with the US-China competition. This research paper analyzes this environment in a comprehensive manner, taking into account the multifaceted drivers shaping regional security dynamics. In addition, it highlights the complex network of alliances and military modernization efforts that are exacerbating the strategic equilibrium within the region. It also explores the complex maritime disputes in the South and East China Seas, highlighting the direct territorial and strategic stakes for both the US and China.

Exploration of the utilization of a new land degradation index in Lake Ebinur Basin in China

Land degradation significantly impacts regional economic development and food security, particularly in arid river basins where soil and water conservation is crucial. Understanding the extent and causes of land degradation is pivotal for effectively prevention and management. This study employs the soil adjusted vegetation index (SAVI), the temperature vegetation dryness index (TVDI), and the salinization detection index (SDI), combined with the analytic hierarchy process and the entropy weight method, to construct a comprehensive land degradation index (LDI). Sen’s slope trend analysis and the Mann-Kendall significance test were used to analyze land degradation trends in the Ebinur Lake watershed from 2002 to 2022. Additionally, the optimal parameters-based geographical detector was used to examine the underlying mechanisms of land degradation. The results indicate the following: (1) From 2002 to 2012, the degree of land degradation in the Ebinur Lake watershed worsened, particularly in the eastern and southeastern parts, as well as in the southern region of Toli County. From 2012 to 2022, land degradation significantly improved, with a notable reduction in degraded land area.

(3) Moderate, severe, and very severe degradation mainly occurred on grassland and unused land, while light degradation and non-degradation primarily occurred on forest land and cultivated land. (4) Unreasonable land use and overgrazing were identified as the primary factors influencing land degradation, with elevation being a secondary factor. The interaction between land use and other factors was found to be most significant, followed by the synergistic effects of grazing quantity with elevation, annual average temperature, gross domestic product, soil moisture, and elevation with annual average precipitation, and temperature. The results of this study offer an empirical basis and taking decisions assistance for land degradation control in the Ebinur Lake Basin, as well as examples and references for assessing land degradation in other places.

Post-Soviet Regional Security Complex Revisited: Is Central Asia Still A Subcomplex?

In this study, Central Asia is addressed within the framework of the Regional Security Complex Theory. In the Regional Security Complex theory developed by Barry Buzan and Ole Wæver, Central Asia is defined as a sub-complex that constitutes the Post-Soviet Regional Security Complex but claims that it can become a separate complex under certain conditions. Twenty years after their pioneering study, the continuities and changes in the region have necessitated an analysis of where the authors’ claim stands. Therefore, in this study, the areas that need to be revised in the original work and the transformations have been evaluated. The study emphasizes the importance of political security in the region’s transformation into a separate complex, but attempts to demonstrate that it cannot yet be considered a separate complex.

A Review of Milled Rice Demand and Supply of Some ASEAN Countries and Lesson Learnt for Cambodia

Rice is a vital crop for ASEAN countries, serving as a primary source of food security and playing a significant role in the regional economy. To draw lessons for rice supply and demand in Cambodia, this article will examine and briefly describe the rice markets in different ASEAN nations, including import and export, rice milling technology, government policy, obstacles, and opportunists. In Cambodia, a program utilizing the sustainable rice cluster (SRC) approach has been developed and put into action by the government in order to maintain the rise of rice production. Compared to traditional approaches, SRC has enhanced rice cultivation by about 40%. The key lessons Cambodia can learn are boosting domestic production, diversifying rice varieties, improving storage and distribution, practicing climate-smart practices, strengthening regional cooperation, improving market access, and farmer empowerment. By analyzing rice demand and supply dynamics in ASEAN and applying the lessons learned, Cambodia can strive to achieve self-sufficiency in rice production and reduce reliance on imports, increase the profitability and competitiveness of the rice sector, enhance food security for its population, and contribute to regional food security within ASEAN.

Ecological Evaluation of Land Resources in the Yangtze River Delta Region by Remote Sensing Observation

The evaluation of land ecological security (LES) evaluates how human activity and land use affect land ecosystems. Its ultimate objective is to provide guidance and assistance for decision making in order to preserve and restore the efficacy and health of terrestrial ecosystems. The assessment model presented in this article is comprehensive and integrates the advantages of both subjective and objective weighting techniques. This study extends the “Pressure–State–Response” (PSR) model to “Driver–Pressure–State-Impact–Response” (DPSIR) and combines it with TOPSISI to determine the weights of each contributing component. Furthermore, the geographical and temporal distribution patterns of regional land ecological security levels were investigated using GIS geostatistical approaches. According to this study, (1) the Yangtze River Delta region’s LES index, with a mean value in the fairly safe range, is generally safe. The year 2019 marks an inflection point for the index, with the highest level of ecological safety on land. The primary element is the modification of environmental policies that are enacted by the government. (2) The LES status is divided into two stages during the course of this study. The Yangtze River Delta region’s LES quickly develops throughout the first stage (2012–2019), which sees a shift in the safety rating from IV to II. The second stage (2019–2023) sees a progressive improvement in the LES index and a shift in the safety category from Class II to Class I. (3) Important variables influencing the geographical distribution of LES in the Yangtze River Delta region include barrier elements, including soil and water erosion areas, flood disaster areas, grain planting areas, urban green covering areas, and effective irrigation areas of farmland.

Identifying and Optimizing the Ecological Security Pattern of the Beijing–Tianjin–Hebei Urban Agglomeration from 2000 to 2030

The conflict between economic development and ecological protection continues to intensify, highlighting the necessity for constructing regional ecological security patterns (ESPs) to reconcile the relationship between development and protection effectively. This study used the GMOP and PLUS model to simulate future land use changes by 2030 under the following three scenarios: natural development (ND), ecological protection (EP), and economic development (ED). Employing the MSPA model and circuit theory, it identified ecological source areas and constructed the ESP for the Beijing–Tianjin–Hebei urban agglomeration (BTH) from 2000 to 2030. The results indicate that the proportion of ecological source areas increased from 22.24% in 2000 to 23.09% in 2020, the EP scenario showing the highest proportion of ecological source areas compared with the other two scenarios. These areas are densely distributed in the northern and western mountainous regions, with sparse distributions in the southern plains. The number of ecological corridors grew from 603 in 2000 to 616 in 2020, with the EP scenario having more corridors than the other two scenarios. From 2000 to 2030, corridors in the northern and western mountainous areas were denser, shorter, and more variable, while those in the southern plains were less dense, longer, and relatively stable. Over two decades, habitat areas for species in BTH increased, while landscape connectivity decreased. Compared with 2020 and the other two scenarios, the EP scenario saw an increase in habitat areas and improved landscape connectivity. The impact on ecological corridors and improvement areas primarily arose from a combination of socio-ecological drivers (e.g., elevation, slope, population), while the influence on restoration and key areas mainly stemmed from ecological factors (e.g., elevation, temperature, NDVI, precipitation). The findings demonstrate that distinguishing different geomorphological units to improve and restore the regional environment, while considering socio-ecological drivers, is crucial for restoring the overall ESP and landscape connectivity of BTH.

Impacts of the land use transition on ecosystem services in the Dongting Lake area

Urbanization-induced land use transitions (LUTs) result in a decline in ecosystem services, which has implications for regional ecological security. In order to explore the relationship between ecosystem services and land use transition, this paper utilizes the InVEST model, a geographically weighted regression (GWR) model, to examine the impact of land use transition on ecosystem services in the Dongting Lake area (DLA). The results showed that 1) with the change in urbanization development, the average values of land use transition intensity (LUI) in 2000, 2010, and 2020 are 237.99, 235.82, and 238.92, respectively. Land use dynamics (LUD) show a tendency to increase and then decrease, with average values of 5.58 and 5.62 for the periods 2000–2010 and 2010–2020, respectively, and the transformation of land use shows obvious spatio-temporal heterogeneity. 2) Habitat quality and carbon sequestration showed a downward trend. In contrast, food supply followed an upward trend; soil conservation (SC) and water yield (WY) services initially increased and decreased later. The overall spatial changes in habitat quality and carbon sequestration appear to be insignificant. Food supply shows significant differences in the plains compared to other areas, while soil conservation and water yield service show significant changes in places other than the DLA. 3) From 2000 to 2020, land use transition dynamics, population density, GDP density, night lighting, and transition intensity had mainly negative effects on ecosystem services. Only the Normalized Vegetation Index (NDVI) showed a positive effect on ecosystem services. The results of the research will provide valuable references for the development and implementation of spatial ecological restoration planning and land use policies in the national territory.

Review and prospect on the construction method of security region for integrated natural gas and power systems

Natural gas and power systems are both important components of modern energy systems. As an efficient and clean peak-shaving power source, natural gas power generation is crucial for ensuring the safe operation of a high-penetration renewable energy power system —supporting China's strategic goal of "carbon peaking and carbon neutrality." However, in recent years, there have been frequent incidents of cascading faults between the gas and power grids. Studying the security region of the integrated electricity-gas system (IEGS) and identifying the system's security margin online is the key to actively preventing such accidents. In view of this, this paper first introduced the typical coupling forms of electricity-gas networks and summarizes the security analysis and evaluation methods from the perspectives of power systems and natural gas systems, respectively. Then, the basic model of the IEGS security region considering the interconnection of gas and electricity networks was extracted, and various methods for solving IEGS security boundaries and dealing with uncertain disturbance factors were compared. Finally, the possible development directions of the construction method of the security region for IEGS were proposed.

Landscape design of urban culture transmission based on the regional information security of Internet of Things

In the context of the rapid development of Internet of Things technology, urban cultural communication and information security have become a new focus in the field of landscape design. This paper innovatively discusses the landscape design of urban cultural communication based on Internet of Things regional information security, aiming at building a safe and culturally rich urban landscape environment. Taking the unique regional culture of Zhangjiajie as an example, this study evaluated the cultural communication effect of landscape design under information security guarantee through in-depth case analysis and field investigation, combined with Internet of Things information security technology. The results show that the cluster head node strategy has significant advantages in resisting physical capture attacks, especially when the number of sensor nodes captured is less than 2000, the information loss rate is less than 0.1. This discovery not only improves the level of information security in the Internet of Things environment, but also provides technical support for the effective dissemination of urban culture. In addition, through the detailed analysis and evaluation of landscape, this study further reveals the important role of landscape design in regional cultural inheritance. To sum up, this study not only provides a new perspective for urban landscape design, but also provides practical guidance for the protection and dissemination of urban culture in the era of Internet of Things.
