Does the Sustainability of the Country Differentiate the ESG of Companies and How It Affects the Relationship between ESG and Firm Value? Evidence from the European Union
Authors: Gawęda Adrian
Published: November 2024

Theoretical background: The paper draws on two relevant theories – stakeholder theory and institutional theory. Non-financial information on how the operations of a company impact its surroundings in environmental, social, and governance (ESG) areas is more and more important in terms of firm value and according to stakeholders theory positive relationship between these two is expected. However, although the research on the relationship between company ESG performance (ESGP) and firm value origins since the beginning of the 1970s, the authors document no conclusive results. Above is theorised to be conditioned by the role of institutions as they reflect a rational purpose that guides behaviours of entities toward certain ends. Purpose of the article: Two aims were set in the study. First, to examine the impact of the sustainability level of the European Union (EU) Member States in the years 2012–2021 on ESGP of non-financial sectors stock companies. The second aim of the paper was to assess the country sustainability level as the factor differentiating the nature and the strength of ESGP impact on firm value of non-financial sectors stock companies listed on the regulated financial markets of EU Member States in the years 2012–2021. Research methods: For the purpose of achieving set goals the study utilised two econometric models. Models were estimated using Panel Least Squares (PLS) regression with Fixed Effects (FE). Tobin’s Q proxied firm value, ESG scoring from Refinitiv proxied company ESGP. Global Sustainability Competitiveness Index (GSCI) from Solability was used as the measure of country sustainability. Company financial and ESG data was sourced from Refinitiv EIKON, while country data was accessed from Solability, Eurostat, Human Development Index and Transparency International. Main findings: Countries of both low and high sustainability level impact company ESGP positively. However, almost twice as big influence of highly sustainable countries was noted for low ones. Research results documented ESG to impact firm value positively. An increase in ESG score of a company from the country with low sustainability level decreased its firm value and the opposite was noted in case of companies of countries with high sustainability level. Investors tend to value positively companies with good ESGP and strong nation-level institutions in the field of sustainability and to punish (i.e. with a lower valuation) firms from countries of poor sustainability, even if these entities reached unexceptionally good ESGP.

Salvadora Valcarce Martínez fue una mujer que vivió por y para la enseñanza. Después de su paso por el Instituto y la Escuela Normal de León obtuvo el título de maestra en 1930. Tras la proclamación de la II República, la joven docente tuvo que realizar cursos de adaptación a la nueva enseñanza moderna e igualitaria. Todos los superó con éxito, por lo que pudo ejercer su profesión de forma interina en Cabeza de Campo desde 1933 hasta 1934, año en queobtuvo la plaza en propiedad de la Escuela Unitaria de Niñas de Cimanes del Tejar. Allí pudo desplegar todas sus destrezas como maestra en línea con los nuevos principios pedagógicos, pero la guerra civil frenó la línea educativa que había emprendido y tuvo que reformarla en consonancia con el modelo de género nacionalcatólico que buscaba mujeres dedicadas a las tareas de esposa y madre. Su carácter resiliente le permitió continuar con su labordidáctica y hacerlo a un nivel elevado, según le fue reconocido por las autoridades académicas con votos de gracia y diversos premios prestigiosos. Tras 47 años como maestra se jubiló y fue homenajeada con numerosos reconocimientos oficiales y con el cariño perpetuo de tres generaciones de alumnas de Cimanes.

Authors: Hernández Paniagua Miguel
Published: November 2024

El efecto de la trashumancia ha sido muy importante para el mantenimiento de los rasgos dialectales en la actual provincia de Salamanca. Los viajes periódicos de los pastores, desde la montaña de León a las sierras del sur de esta provincia, supusieron un efecto continuador en el habla desde los primeros tiempos de los asentamientos medievales de colonos. Estos rasgos siguieron bastante presentes hasta la llegada de las comunicaciones de masas.

Published: November 2024

Aim. To study the concentration of immunoglobulin free light chains (FLCs) in patients with myocarditis in comparison with non-inflammatory heart diseases, their relationship with inflammatory markers and the severity of chronic heart failure (CHF).

Material and methods. This study included 77 patients (31 women, mean age 54.1±13.3 years): 41 patients with myocarditis verified by myocardial biopsy (n=18) or using a noninvasive diagnostic algorithm, 31 patients with noninflammatory CHF (comparison group), and 5 patients with monoclonal gammopathy identified during the study (4 of them were diagnosed with AL amyloidosis with heart damage). In the myocarditis group, CHF was diagnosed in 29 patients, mean stage IIA, functional class (FC) 2-3, with a mean left ventricular ejection fraction 43%. In the comparison group, patients had predominantly IIA stage, FC 2-3 CHF without systolic dysfunction. The blood concentration of kappa and lambda FLC types was measured with Cloneus S-FLC-K TIA Kit and Cloneus S-FLC–L TIA Kit. Concentrations were considered normal at FLC-kappa 4.84-14.20 mg/l, FLC-lambda 7.03-22.50 mg/l, and the FLC-kappa/lambda ratio 0.426-1.050.

Results. Increased FLC concentrations were found in 58% of patients with myocarditis and in 77% of patients in the comparison group. The FLC-lambda concentration was significantly higher in the comparison group; there were no significant differences between the groups in FLC-kappa and their ratio. The closest significant correlations in both groups and the entire cohort were noted between FLCs of either type and CHF, as well as the requirement for loop diuretics (correlation coefficients, 0.60-0.90), independent on the severity of systolic dysfunction. Myocarditis patients also showed correlations of FLCs with the titer of antibodies to cardiomyocyte nuclear antigens, levels of C-reactive protein, leukocytes, neutrophils, erythrocyte sedimentation rate, and the concentration of N-terminal fragment of brain natriuretic peptide. In a subgroup of 10 myocarditis patients who were treated with immunosuppressants, FLCs of both types were significantly lower than in the comparison group; only with the persistence of severe CHF was an increase in FLCs noted.

Conclusion. An increased FLC concentration can be considered as an important pathogenesis component that reflects both the specific mechanisms of myocarditis and the severity of CHF. In the absence of a statistically significant increase in general inflammatory markers in the blood of myocarditis patients, the measurement of FLCs can be used as an additional diagnostic marker and predictor of the decompensated variant of the course of myocarditis. However, the diagnostic and prognostic significance of FLC concentration in patients without CHF requires a further study.

Authors:   Head of the Department of Financial Law and Customs Activity of the Law Institute of the Vladimir State University, PhD (Law), Associate Professor, Pogodina Irina V.
Published: November 2024

Purpose. To determine the limits of the integrative nature of the category “trust in government” and analyze the mutual influence of the level of trust in government and management and the level of civic activity of the population, as well as raise the question of the dual influence of the process of strengthening trust in government. Methodology: dialectics, analysis. Conclusions. On the one hand, trust is a factor in the stability of the state system and a predictor of active civic participation. Strengthening trust in the authorities on the part of the population is permanently necessary. But, on the other hand, a high level of trust in the authorities reduces the indicators of civil participation of the population in solving the affairs of society and the state. Due to the fact that increasing the level of trust, as practice shows, reduces the civic activity of the population, it is necessary to look for ways to activate the participation of citizens in the affairs of society and the state, to create a culture of participation in society while strengthening trust in the activities of government bodies. Scientific and practical relevance: scientific and practical significance. The article is aimed at raising questions for the research activities of legal scholars and the work of practitioners about finding directions for activating civic participation, a balance between measures to increase trust in authorities and maintaining citizens’ interest in participation, co-production and management.

Authors: De Assis Jefferson R. P. , Gomes Andréia da S. , Gomes Hugo M. T. C. , Costa Fabiano F. , Felipe Wellington F. , Corrêa Maurício B. de R. , Fernandes Darlan A.
Published: November 2024

In this work, a comparative study is presented to evaluate the performance of iterative methods to solve nonlinear systems applied to grid impedance estimation. The iterative methods of Newton-Raphson, Potra-Pták, and Chun were embedded in the control system of a three-phase inverter supported by a photovoltaic plant connected to the grid. The adopted impedance estimation technique consists of successive variation of the power injected into the grid, more precisely, at three different levels. The voltage and current amplitudes at the point of common coupling~(PCC) are monitored and serve as input for the iterative methods, which, after processing them, provide an estimate of the grid impedance. To compare the performance between the methods, the following merit figures were listed: execution time, number of iterations required to deliver the estimates, percentage error, efficiency index, computational efficiency, computational efficiency index, and stability of the iterative method. The results presented were obtained through real-time simulations. From that, it was possible to conclude about the method with the best performance, thus contributing to greater assertiveness on the part of designers when choosing the most efficient iterative method to be embedded in a microcontroller for grid impedance estimation purposes.

This study aims to determine the technicalities and analyze the feasibility of snakehead fish (Chana striata) hatchery using round ponds in Labuan Amas Selatan District. The data collection methods used are observation, interviews, and documentation. The data analysis used is a qualitative descriptive analysis to determine the technical aspects of the fish hatchery, financial analysis to determine the feasibility of the business with profit analysis, Payback Period (PP), Break Event Point (BEP), Net Present Value (NPV), Net Benefit Cost (Net B/C), and Internal Rate of Return (IRR). The study results show that snakehead fish hatchery using round ponds produces snakehead fish seed in 7 cycles in one year; in each cycle, 6–10 pairs of snakehead fish are used, which can be spawned with an average nursery time of 1.5 months. Snakehead fish cultivation techniques include broodstock maintenance, broodstock selection, spawning, larval transfer and maintenance, nursery, harvesting, and marketing. The results of the business feasibility analysis obtained a profit value of IDR 63,465,000/year with a speedy return on investment for 1.64 years, the BEP value of production = 20,742 seed < the production value = 56,000 seed, and the BEP price of IDR 667/seed < the current price = IDR 1,800/seed. The NPV value at the hatchery reached IDR 366,007,925, meaning NPV > 0, Net B/C > 1 value of 4.62, and IRR value of 62.81%, which means it is greater than the current interest rate of 6%. Based on various financial analyses, the snakehead fish hatchery business using round ponds is profitable and feasible.

Published: November 2024

Este artigo teve por objetivo investigar as estratégias adotadas por redes estaduais de educação durante o período da pandemia da covid-19. Para isso, foram utilizadas as respostas das escolas ao questionário “Resposta Educacional à Pandemia de Covid-19 no Brasil” aplicado pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (INEP), nos anos de 2020 e 2021, como suplemento do Censo Escolar. Foram destacadas as questões referentes às estratégias pedagógicas e de gestão e àquelas adotadas por professores e alunos. Os resultados apontaram para a adoção desigual de ações pelos estados, o que pode ter relação com s capacidades técnicas e institucionais desses entes, ao mesmo tempo em que se pôde identificar tendências como a adoção da reorganização curricular em 2020 e a busca ativa de alunos em 2021. Junto aos professores, a estratégia mais utilizada por escolas e redes foi a realização de reuniões virtuais, assinalada por quase todas as escolas desde 2020; e as que menos ocorreram foram a disponibilização de equipamentos e de acesso à internet e o treinamento para o uso de ferramentas tecnológicas. Com os alunos, destacaram-se a comunicação entre escola e estudantes e a disponibilização de materiais impressos. Já a disponibilização de equipamentos ou de acesso à internet para esse público ficou abaixo de 40%. Isso ressalta a importância do vínculo entre escola, família e comunidade na tomada de decisões e combate à evasão.

Experience of Pension Security for the Self-Employed in OECD Countries and Possibilities of Its Application in Russia
Authors: Syndyashkina E.
Published: November 2024

The processes of destandardization of employment and a reduction in the scope of traditional hired labor, which are actively developing in the modern labor market, create significant problems and imbalances in pension systems, exacerbating the negative impact of demographic factors. In the time of growth in various forms of self-employment, an urgent task of pension policy is to ensure a balance between the interests of the self-employed, standard and non-standard employees and the financial capabilities of the budget; between the sustainability of the pension system and the adequacy of pensions for all participants. The article considers the problems of pension provision for the self-employed in OECD countries and Russia. Various approaches to pension provision for the self-employed, their strengths and weaknesses, associated challenges and risks for pension systems are analyzed. Particular attention is paid to the possibilities of using foreign experience in Russia. There are limited opportunities to pay contributions for the majority of self-employed people and they lack interest in voluntary pension insurance due to the low size of their future pension. Attention is also drawn to the risk of outflow of self-employed people from the registered segment in the event of the introduction of mandatory pension contributions. It is concluded that in present day Russia it is advisable to maintain the voluntary participation of the self-employed in the pension system in combination with increasing motivation to join the long-term savings program by introducing additional preferences for the self-employed, for example, an increase in the terms and share of state co-financing.
The Transformation of the Arctic Council and the Barents Euro-Arctic Council amid the International Crisis of 2022
Authors: Chistikov M.
Published: November 2024

The international political crisis of 2022 has become one of the most important phenomena within the existing system of international relations (IR) and has had an impact on virtually all international processes, including those in the Arctic region. The Arctic occupies a key position in contemporary international relations, as it is the region where the border between Russia and NATO countries, including the United States, lies. The impact of the crisis on the Arctic subsystem of IR is understudied. Much of the research focuses on reconstructing the events within the processes that took place in the region. Nevertheless, researchers have found that international regimes that are more institutionally rigid have shown greater resilience under crisis conditions. In turn, the Arctic Council and the Barents Euro-Arctic Council, international regimes with a similar institutional structure, differed in their dynamics amid the 2022 crisis. While the Barents Euro-Arctic Council has completely stopped cooperating with Russia, the Arctic Council has seen a recovery trend after a period of ‘freezing’. In order to identify the reasons that determined the observed differences in the dynamics of transformation of these institutions, the paper used the theoretical approach of simple and broader effects of international regimes. The number of positive simple and broader effects of the Barents Euro-Arctic Council was found to be significantly lower than those of the Arctic Council. In the context of simple effects, the reasons for the disparity are: coverage of issue areas according to the participants’ vantage points in terms of participants and geography, along with funding, while in terms of extended effects: the degree of ideologization of an institution and opportunities for political engagement at a relatively high level. A key limitation of the methodology used relates to the fact that, by looking at regimes in a functional logic, other factors are not taken into account. Nevertheless, the differences in the transformation of the Arctic Council and the Barents Euro-Arctic Council as a result of the crisis may also be related to the differences in the Russia-Norway and Russia-Finland relationships.

Several copolymer hydrogels were prepared from free radical copolymerization of 2-hydroxyethyl methacrylate (HEMA) with itaconic acid (IA). A series of Poly(2-hydroxyethyl methacrylate-co-itaconic acid) hydrogel, poly(HEMA-co-IA) were prepared at different feed monomer ratio using ammonium persulfate (APS) initiators in water at 70°C. The phytodrug 2,4-dichlorophenoxy acetic acid (2,4-D) were grafted to Poly(HEMA-co-IA) by esterification reaction. In addition, swelling behavior (Wt%) was studied at different pH. The hydrolysis of Poly(HEMA-co-IA)-2,4-D showed that the release of the bioactive compounds in aqueous phase, using Liquid-phase polymer-based retention (LPR) ultrafiltration system is dependent on the hydrophilic character as well as on pH value. The acid-hydrolysis of the herbicide from the conjugates follows a first order kinetics, showing higher kinetic constants as the pH increases. The base-catalyzed hydrolysis reaction of the herbicide follows a zero order kinetic, where the basic medium acts as a catalyst accelerating the release rate of the herbicide, showing higher kinetic constants as the pH increases. The differences in the release rates found for the hydrogel-herbicide at different pH can be correlated with the difference in their swelling capacity, where the release rate generally increases with an increase in the swelling capacity from water solution at higher pH. The study of the release process revealed that all samples in distilled water at pH 10 are representative of agricultural systems, showed first-order swelling kinetics and an absorption capacity that conforms to the parameters for hydrogels for agricultural application, which supports their potential for these purposes.
Avifaunal Diversity and Conservation Challenges in the Magat Wetland of the Philippines: Assessing the Impacts of Habitat Loss and Management Strategies
Authors: Bimmoy Eric
Published: November 2024

This study investigates avifaunal diversity in the Magat Wetland areas in the Philippines, which serve as habitats for both endemic and migratory bird species. Using transect surveys and data from Department of Environment and Natural Resources (DENR), the research recorded 24 bird species, with dominant populations of E. garzetta and A. luzonica. Moderate avifaunal diversity, reflected in a Shannon-Wiener Diversity Index of 1.62, suggests an ecologically stable environment with critical resources supporting both abundant and rare species. However, pressures from habitat loss due to aquaculture, agricultural expansion, and tourism activities pose ongoing challenges for conservation. Local government efforts, including the establishment of a bird-watching site and eco-tourism initiatives, have raised awareness and engaged communities in conservation. Statistical modeling revealed that for each 1% increase in forest cover, the avian population is expected to increase by about 84 individuals, holding other factors constant. This highlights forest cover loss as a key factor affecting avifaunal populations, underscoring the importance of habitat preservation. Future research should focus on understanding the impact of human activities, climate change, and habitat quality on bird populations. This research underlines the critical role of the Magat Wetland as a biodiversity hotspot, advocating for sustainable management practices to preserve its ecological integrity amid increasing human development pressures.

Published: November 2024

This research investigates the relationship between sustainable human resource management (SHRM) practices and employee happiness, with a focus on the mediating role of employee engagement. Using a sample of 473 women workers from one of India’s largest tea plantations, the study found a significant positive relationship between SHRM practices and employee happiness. Additionally, employee engagement was shown to mediate this relationship, indicating that SHRM practices enhance employee happiness primarily through increased engagement. The research aims to assess how sustainable human resource management affects workplace happiness among the women employees in the Indian tea plantation sector.
The data was analyzed using IBM SPSS 25, and the research model was developed with WarpPLS 8.0. The study adopted Ehnert’s (2009) Sustainable Human Resource Management Practices, Singh & Aggarwal's (2017) Employee Happiness Scale (Happiness at Workplace), and Schaufeli et al.'s (2012) Employee Engagement Scale. The findings reveal a strong positive relationship between sustainable human resource management and employee happiness, with a correlation value of 0.943 at a significance level of 0.01. Moreover, there is a significant positive association between employee engagement and workplace happiness, with a correlation value of 0.947 and an R² of 0.99. These results confirm a robust positive relationship among sustainable human resource management, employee engagement, and employee happiness. This relationship emphasizes that fostering a positive work environment can significantly enhance employee engagement, leading to improved overall performance.

Vision-language-action (VLA) models represent a promising direction for developing general-purpose robotic systems, demonstrating the ability to combine visual understanding, language comprehension, and action generation. However, systematic evaluation of these models across diverse robotic tasks remains limited. In this work, we present a comprehensive evaluation framework and benchmark suite for assessing VLA models. We profile three state-of-the-art VLM and VLAs —GPT-4o, OpenVLA, and JAT—across 20 diverse datasets from the Open-X-Embodiment collection, evaluating their performance on various manipulation tasks. Our analysis reveals several key insights: (1) current VLA models show significant variation in performance across different tasks and robot platforms, with GPT-4o demonstrating the most consistent performance through sophisticated prompt engineering, (2) all models struggle with complex manipulation tasks requiring multi-step planning, and (3) model performance is notably sensitive to action space characteristics and environmental factors. We release our evaluation framework and findings to facilitate systematic assessment of future VLA models and identify critical areas for improvement in the development of general-purpose robotic systems.

Published: November 2024

Tractors operate under varying and unpredictable conditions, making energy management strategies insufficient for maintaining system power dynamics, which often leads to reduced traction power and overall efficiency. To overcome this challenge, a fuzzy-following energy management strategy was developed. This approach utilizes fuzzy control based on energy following to optimize the tractor’s energy output, ensuring more stable power delivery. A target tractor model was constructed using CRUISE, and joint simulations were carried out via the CRUISE-Simulink interface. The results demonstrated that the fuzzy-following strategy stabilized the battery’s state of charge (SoC) and improved fuel economy. The strategy was implemented for controlling a hybrid tractor, and its effectiveness and stability were validated through drivetrain system tests and real vehicle trials under light load, plowing, and power harrowing conditions, successfully achieving power balance under these diverse operating scenarios. Comparative tests between the hybrid tractor using the fuzzy-following strategy and a powershift tractor revealed that the hybrid tractor exhibited superior plowing efficiency and fuel economy under plowing and power-harrowing conditions.
