Теоретические и практические аспекты формирования системы индикативных показателей диагностики экономической безопасности холдинговых структур

The article introduces the case of economic security analysis of the Romashin Technology Research and Production Holding, Obninsk, Russia. The author relied on various theoretical and practical aspects of economic security indicators as a system. The holding in Obninsk united seven enterprises, each of which conducted its own business activities. As a result, a timely preventive diagnosis of risks and threats became a rather complicated issue.The research objective was to identify and justify a set of economic security indicators for the holding in question. A comprehensive analysis of financial reports of all organizations within the holding made it possible to identify external and internal threats to the economic security of the entire holding and its parts. The diagnostics was carried out on the basis of safety indicators, which were divided into safety groups. If the indicators were outside the regulatory level, the holding was recommended to stabilize them. The study also revealed some opportunities for further development, as well as yielded measures to eliminate the negative external impact. Government Decree No. 351, March 12, 2022, allowed Russian companies not to publish reports, thus protecting them against potential harm from unfriendly countries. However, the Decree prevented the author from getting access to the current financial data, which made the analysis retrospective.

Современное состояние и тенденции развития сельскохозяйственной потребительской кооперации

Today, small forms of management in the Russian agro-industrial complex occupy a significant share in the structure of producers for certain groups of agricultural raw materials and food. Institutional transformations that have taken place over decades in the agro-industrial complex have shown the viability of such a form of organization as agricultural cooperation. The advantages that determine the competitiveness of cooperation include reducing transaction costs, economies of scale, increasing the share of rural producers in the final price of products, etc. Modern socio-economic trends dictate new conditions for the formation of food chains and the participation of economic entities in them. In this connection, there is an urgent need to analyze trends in the development of agricultural consumer cooperation. This will make it possible to determine strategic directions for development and justify relevant measures of state support for both small business forms themselves and the cooperative form of their organization. The purpose of the study is to comprehensively analyze and substantiate the development trends of the institution of agricultural consumer cooperation, as the most important component of ensuring food security in Russia in modern conditions. Achieving this goal involves the use of general scientific methods of cognition (historical and logical, comparative and system-structural) and traditional methods of economic analysis. The trends in the development of the Institute of Agricultural Consumer Cooperation have been studied. A comprehensive analysis of the competitive advantages and weaknesses of small business forms in the agro-industrial complex was carried out. The potential for growth of the institution of agricultural consumer cooperation in the conditions of transformation of the socio-economic space has been identified. The experience of supporting agricultural cooperatives in the constituent entities of the Russian Federation was studied. Measures of state support for the development of this institution that are relevant to current trends in economic development are substantiated. The results of the study and the conclusions drawn on their basis will be useful for supporting management decisions in the field of development of the agro-industrial complex, increasing the efficiency of planning and implementing state support for the small business sector in the agro-industrial complex

Plate osteosynthesis of phalanx fractures using wide-awake local anesthesia no tourniquet technique is cost-effective and associated with less postoperative pain.

The wide-awake local anesthesia no tourniquet (WALANT) technique, which is based on the local infiltration of lidocaine and epinephrine, is widely used in hand and wrist surgery. However, few studies have been conducted on the cost-benefit analysis of phalanx fracture surgery using the WALANT technique. This study aimed to investigate the clinical condition, time spent on anesthesia and operation. We also perform an economic analysis among general anesthesia, local anesthesia with a tourniquet, and the WALANT technique for plate fixation of phalanx fractures. This retrospective study included all patients with single phalanx fractures who underwent open reduction internal fixation with plating between January 2015 and December 2019. Patients were divided into three groups according to the anesthesia method: general anesthesia with a tourniquet (GA group), local anesthesia with a tourniquet (LA group), and the WALANT technique (WALANT group). Data, including demographics, anesthesia and surgical time, postoperative pain score, and vomiting ratio, were collected and analyzed. A total of 62 patients were included in this study. Of the 62 patients, 15 were included in the GA group, 32 in the LA group, and 15 in the WALANT group. No complications were reported during surgery or follow-up in either group. The GA group exhibited a significantly longer anesthesia time than the other two groups, with an average of 32.4 min. However, no significant difference in surgical time was observed among the three groups. The WALANT group exhibited a significantly lower postoperative pain score than the other two groups. The additional cost of general anesthesia was approximately 350 US dollars (USD), accounting for approximately one-third to one-fourth of the total expenses for phalanx surgery. Open reduction with plate fixation of phalanx fractures using the WALANT technique and local anesthesia was cost-effective compared with general anesthesia. Patients who underwent phalanx fracture surgery using the WALANT technique experienced less pain on the first postoperative day than those who underwent surgery using general or local anesthesia with a tourniquet because of the adequate tumescent technique and not using a tourniquet during surgery.

Исследование рисков экономической безопасности территорий в период неопределенности, вызванной пандемией

The article describes economic insecurity that occurs in a time of uncertainty and affects human development and social well-being. The authors defined indicators to analyze, identified and justified the vector of state policy, and studied the socio-economic issues of territorial development as a source of risks. The dataunder analysis were obtained from public sources, systematized, and subjected to economic analysis using the methods of absolute, relative, and mean values, as well as graphical and logical methods. The period under study covered 2018–2022, which made it possible to assess the impact of the uncertainty caused by the COVID 19 pandemic on the Russian federal districts by analyzing indicators of economic security. The research revealed economic and social risks, as well as the state policy in leveling them across the country. The pandemic triggered economic uncertainty, which destabilized the social well-being and development opportunities of the population in the regions. The current state policy provides long-term transformations and allows the population to adapt to changes.

Fluoride removal using a rotating anode electro-coagulation reactor: Parametric optimization using response surface methodology, isotherms and kinetic studies, economic analysis and sludge characterization

The presence of fluoride in drinking water can cause various diseases, such as dental fluorosis and skeletal fluorosis. The present study aims to intensify the fluoride removal using a rotating anode electro-coagulation (EC) reactor with providing the proper hydrodynamics conditions. This fluoride removal is modeled and optimized using Response Surface Methodology (RSM) and central composite design (CCD) with varying operational parameters (rotation speed: 20–80 RPM, current: 0.2–1.0 A, initial fluoride concentration: 8–40 mg/L and time: 15–75 min). The maximum fluoride removal is obtained as 96.87% (predicted) and 95.40% (experimental) for the optimized process parameters, initial concentration of 32 mg/L, 0.8 A current, 60 min, and 60 RPM of rotating speed. Kinetic analysis reveals that the removal process adheres to a second-order kinetic model, suggesting that the rate of fluoride removal is dependent on the concentration of fluoride ions present. Isothermal studies indicate that the effective sorption of fluoride onto the generated flocs follows a sips isotherm. The optimal cost analysis is carried out to determine the operational cost as 0.256 USD/m3 for F removal of 93.49% at initial concentration 24 mg/L, time 50 min, current 0.7 A, and rotation 70 rpm and presenting a cost-effective solution for fluoride mitigation. Further, characterizations of the resultant sludge through X-Ray Diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), and the Toxicity Characteristic Leaching Procedure (TCLP) confirmed the safe disposal potential of the sludge. The findings show a promising approach for fluoride removal, combining high efficiency, economic viability, and environmental safety.

Mn‐Fe dual‐metal Assemblages on Carbon‐coated Al2O3 Spheres for Catalytic Ozonation Oxidation: Structure, Performance, and Reaction Mechanism

Catalysts with high catalytic activity and low production cost are important for industrial application of heterogeneous catalytic ozonation (HCO). In this study, we designed a carbon‐coated aluminum oxide carrier (C‐Al2O3) and reinforced it with Mn‐Fe bimetal assemblages to prepare a high‐performance catalyst Mn‐Fe/C‐Al2O3. The results showed that the carbon embedding significantly improved the abundance of surface oxygen functional groups, conductivity, and adsorption capacity of γ‐Al2O3, while preserving its exceptional mechanical strength as a carrier. The prepared Mn‐Fe/C‐Al2O3 catalyst exhibited satisfactory catalytic ozonation activity and stability in the degradation of p‐nitrophenol (PNP). Electron paramagnetic resonance (EPR) and quenching experiments reveal that radical (•OH and •O2–) and nonradical oxidation (1O2) dominated the PNP degradation process. Theoretical calculations corroborated that the anchored atomic Fe and Mn sites regulated the local electronic structure of the catalyst. This modulation effectively promoted the activation of O3 molecules, resulting in the generation of atomic oxygen species (AOS) and reactive oxygen species (ROS). The economic analysis on Mn‐Fe/C‐Al2O3 revealed that it was a cost‐competitive catalyst for HCO. This study not only deepens the understanding on the reaction mechanism of HCO with transition metal/carbon composite catalysts, also provides a high‐performance and cost‐competitive ozone catalyst for prospective application.

Negotiated strategic regional planning: emerging practice in the London–Cambridge corridor

Formal regional planning structures were abolished in England in 2011. One response has been to call for their restitution, another has been to argue instead for negotiated strategic regional planning. The latter envisages the formation of partnerships in lieu of formal structures, with two key benefits being it is less vulnerable to government tinkering and is more attuned to economic and political actors. We employ a proxy – the UK Innovation Corridor – to look at the possibilities for negotiated strategic planning. This leads us to conclude that a hybrid model of formal and negotiated regional planning would offer a more robust model.

Additionally, the economic analysis of three independent battery technologies, notably lead acid, lithium-ion, and nickel-iron are carried out to find the economically feasible technology, to ensure uninterrupted power supply. Moreover, reliability and sensitivity analyses of the optimized microgrid using POA were conducted for various reliability indices and variable interest rates. Results show that proposed POA method provides the optimal island microgrid configuration with lead acid (LA) batteries (PV/WT/LA/DG) based on a minimum LCC of $8334901, COE of 0.1080$/KWh and greenhouse gas emission amount of 19664 kgs/year. Furthermore, the outcomes generated by the POA are compared with genetic algorithm, particle swarm optimization, moth flame optimization algorithm, whale optimization algorithm and grey wolf optimization. It is found that POA method achieves more competitive results compared to other optimization techniques due to its ability to adjust parameters, fast convergence speed, and straightforward computations.

Optimal Sizing and Economic Analysis of Community Battery Systems Considering Sensitivity and Uncertainty Factors

Efficient sizing and economic analysis of community battery systems is crucial for enhancing energy efficiency and sustainability in rooftop PV panel-rich communities. This paper proposes a comprehensive model that integrates key technical and economic factors to optimize the size and operation of the prosumer-owned battery, maximizing the financial returns over the life span of the battery. Sensitivity and uncertainty analyses were also conducted on a number of factors that are constantly changing over the years such as per-unit cost of the battery and interest rate. Monte Carlo simulations were utilized to replicate the unpredictable PV generations and the volatility of house load demands. The developed model is evaluated under three scenarios: a shared community battery for all houses, individual batteries for each house, and a combined system with an additional large load. Particle Swarm Optimization (PSO) is utilized to maximize the formulated objective function subject to the considered constraints. The findings indicate that integrating community batteries offered a substantial economic advantage compared to individual home batteries. The additional revenue stream of incorporating larger consumers looking to reduce their carbon footprint (e.g., commercial) returned a further augmented net present value (NPV). The influence of different tariff structures was also assessed and it was found that critical peak pricing (CPP) was the most prolific. The outcomes offer valuable insights for policymakers and stakeholders in the energy sector to facilitate a more sustainable future.

Comparative study on productivity of double slope solar still using different wick and energy storage materials

The aim of the proposed study is to evaluate the efficiency of Double Slope Solar Still (DSS) using different wick and energy storage materials. In the study, wick materials such as jute, cotton and sponge were used in combination with energy storage materials such as mild steel, cast iron and copper. The experiments were conducted using DSS with different combinations of wick and energy storage materials to determine the efficient performance combination. The results show that sponge and copper have higher efficiency with wicks and energy storage materials. The results show that the maximum amount of water produced in a single day was 3147 ml when the DSS system was used with a combination of sponge and copper materials. This range shows an increase of 17.47 % and 12.44 % over the DSS with jute and copper and the DSS with the combination of cotton and copper respectively. The DSS showed the highest average energy efficiency when used in conjunction with a combination of sponge and copper, namely 51 % of the average efficiency. This corresponds to an increase of 18.60 % and 10.86 % compared to the combination of DSS with jute and copper and the combination of DSS with cotton and copper respectively. The best evaporation heat transfer coefficient of 345 W/m2K was determined for the combination of DSS with sponge and copper. Average exergy efficiency is also maximum of 3.076 % for the DSS with sponge and copper materials, which is higher than other investigated combinations. The proposed system has an energy payback period of 1.26 years, an energy production factor of 0.78, a life cycle efficiency of 6.9 % and a cost of $0.031 per litre of water produced in the environmental economic analysis.

Background: Dairy farming is a cornerstone of the rural economy in India. Maharashtra, particularly its drought-prone districts, is critical in this sector. Despite challenges posed by erratic monsoons and limited irrigation, dairy farming remains a viable strategy for economic stability in these regions. The aim of this study was to examine the financial aspects of dairy enterprises, focusing on socio-economic characteristics, economic viability and constraints faced by farmers. Methods: The study employed a multistage stratified random sampling method. Key analytical tools included average and percentage calculations, BEP analysis and a Cobb-Douglas production function. Additionally, Garrett’s ranking technique was used to ascertain constraints in dairy farming, while the MOTAD model assessed profitability and risk. Result: The findings reveal that crossbred cow milk production is more lucrative than buffalo milk production, despite its higher average total expenditure per lactation. Break-even analysis confirmed profitability for both types of milk producers. Key determinants of milk production, such as green fodder, concentrate and labour, suggest areas for efficiency enhancements. Farmer-identified constraints include high feed costs, insufficient veterinary services and water scarcity. Utilizing the MOTAD model, the study recommends integrating dairy farming with crop cultivation to maximize returns, mitigate risks and enhance overall farm resilience in challenging environmental conditions.

Indonesian governance: Reflections and how to reduce disparity between regencies/cities in Indonesia

Nawacita work program of Indonesian Governance aims to actualize a golden Indonesia by 2045 by accelerating development and human resources. However, the Indonesian people face several difficult problems of their own. Several strategic policies have been put into place in Indonesia to promote fair development and lessen regional differences. These policies include macroeconomic management, economic deregulation, the development of new resources economically, the maritime economy, and productivity enhancement. The Nawacita program’s reflection in addressing regional imbalances in Indonesian regencies and cities is covered in this report. This study employs quantitative and bibliographic techniques along with political economic analysis methodologies to investigate in-depth and information. The study’s findings indicate that although differences between Indonesia’s districts and cities are gradually narrowing, the country’s GDP per capita is still below the global average. Most of the strategic measures put in place by the Indonesian Governance have not resulted in the anticipated expansion of the economy. Nonetheless, in current period of government, connectivity in enhancing productivity across regions through Indonesia centric development is a primary objective to ease accessibility between areas, which has frequently been disregarded. particularly in the Papua region, which has not exactly developed and been left behind. According to the Analytical Hierarchy Process (AHP) analysis’s findings, increasing productivity is a task that needs to be finished right now to lessen regional differences in Indonesia.

The Impact of Policy Quality and Political Stability on Foreign Direct Investment in ASEAN Countries: An Institutional Economics Analysis

This investigation pivots on the impact of policy quality and political stability on foreign direct investment within ASEAN countries. Both facets form essential components of a country's political risk profile; a lower risk profile, characterized by sturdy policy quality and political stability, tempts investors to channel their capital into preferred investment destinations. Our research employs a panel data regression analysis across seven ASEAN nations; Indonesia, Malaysia, Singapore, Thailand, Vietnam, the Philippines, and Brunei Darussalam, from 2012 to 2022. The Common Effects Model emerged as the optimal panel model during our study. We found that policy quality negatively impacts foreign direct investment, signifying that investments are perceived unprofitable due to the policy quality in the ASEAN region. In counterpoint, political stability has a positive effect, confirming that stable political circumstances in the ASEAN region draw investor interest. These significant findings validate that policy quality and political stability significantly sway foreign direct investment within ASEAN countries, making them crucial considerations for prospective investors.

Genomic Surveillance for Enhanced Healthcare Outbreak Detection and Control.

Current methods are insufficient alone for outbreak detection in hospitals. Real-time genomic surveillance using offers the potential to detect otherwise unidentified outbreaks. We initiated and evaluated the Enhanced Detection System for Healthcare-associated Transmission (EDS-HAT), a real-time genomic surveillance program for outbreak detection and mitigation. This study was conducted at UPMC Presbyterian Hospital from November 2021 to October 2023. Whole genome sequencing (WGS) was performed weekly on healthcare-associated clinical bacterial isolates to identify otherwise undetected outbreaks. Interventions were implemented in real-time based on identified transmission. A clinical and economic impact analysis was conducted to estimate infections averted and net cost savings. There were 3,921 bacterial isolates from patient healthcare-associated infections that underwent WGS, of which 476 (12.1%) clustered into 172 outbreaks (size range 2-16 patients). Of the outbreak isolates, 292 (61.3%) had an identified epidemiological link. Among the outbreaks with interventions, 95.6% showed no further transmission on the intervened transmission route. The impact analysis estimated that, over the two-year period, 62 infections were averted, with gross cost savings of $1,011,146, and net savings of $695,706, which translates to a 3.2-fold return on investment. Probabilistic sensitivity analysis showed EDS-HAT was cost-saving and more effective in 98% of simulations. Real-time genomic surveillance enabled the rapid detection and control of outbreaks in our hospital and resulted in economic benefits and improvement in patient safety. This study demonstrates the feasibility and effectiveness of integrating genomic surveillance into routine infection prevention practice, offering a paradigm shift in healthcare outbreak detection and control.

The Impact of Decree 70/2023 on Labor Regulation and Industrial Relations in Argentina: A Legal and Economic Analysis

Decree 70/2023, issued by the Argentine government, addresses critical issues in labor and industrial relations amidst ongoing economic and social challenges. This study evaluates the decree’s impact on labor regulations, focusing on minimum wage standards, protection against unfair dismissal, and dispute resolution mechanisms. Utilizing a mixed-methods approach, both qualitative and quantitative analyses were conducted. Qualitative methods included legal document reviews and expert interviews, while quantitative methods involved assessing changes in wage levels, unemployment, and productivity. Key findings indicate that the decree’s increase in minimum wage aims to enhance worker welfare and stimulate economic growth, but poses challenges for employers, particularly small and medium-sized enterprises. Stricter procedures and improved compensation for layoffs are expected to reduce job insecurity and foster fairer employment practices, though these measures may raise operational costs and administrative burdens for businesses. Additionally, the new dispute resolution mechanisms, which emphasize mediation and arbitration, are designed to resolve conflicts more efficiently and transparently. However, consistent implementation and oversight remain critical challenges. The study concludes that while Decree 70/2023 represents a significant step towards better labor conditions and industrial relations in Argentina, its success will depend on rigorous enforcement and stakeholder cooperation. Further research should focus on the long-term effects of these regulations on Argentina’s labor market and economic stability, as well as continuous evaluation to refine these policies for optimal outcomes.

Assessing China's solar power potential: Uncertainty quantification and economic analysis

Solar power is vital for China's future energy pathways to achieve the goal of 2060 carbon neutrality. Previous studies have suggested that China's solar energy resource potential surpass the projected nationwide power demand in 2060, yet the uncertainty quantification and cost competitiveness of such resource potential are less studied. Therefore, we applied an integrated framework to simulate China's solar photovoltaic (PV) technical potential, and incorporated potential uncertainty stemming from climate change, land use dynamics, and technological advancements. In addition, we constructed the solar energy supply curve for each province and calculated the economic potential. According to our results, approximately 78.6 % and 99.9 % of China's technical solar PV potential are priced lower than the benchmark price of coal-fired energy in pessimistic and optimistic scenario. These findings highlight the significant technical and economic potential of solar PV as a cost-effective alternative to coal-fired electricity to meet China's growing electricity demands.
