The category “rural areas”: approaches to defining the concept, basic functions
Authors: Kovach Alina Ya.
Published: April 2024

The article examines variations in the interpretation of the category “rural areas” by various scientists and draws attention to the importance of rural areas for the development of the country’s agro-industrial complex. Theoretical approaches to defining the essence of this concept are characterized, namely: territorial, spatial, systemic, structural, and multi-criteria. The advantages and disadvantages of these approaches are highlighted. Proponents of the structural approach consider rural areas through the prism of their structure, parts, elements, and functional units. Proponents of the spatial approach describe rural areas as a space characterized by population and economic resources. Representatives of this approach interpret rural areas as a system. The systemic approach makes it possible to consider the components of rural areas both in relation to each other and in interaction with the components of other systems. This, in turn, makes it possible to single out a significant part of the properties of rural areas, such as structure, integrity, hierarchy, autonomy, and sustainability. Representatives of the territorial approach emphasize three components of the rural area – content, phenomenon, and result. Representatives of the multi-criteria approach use several criteria to define the category “rural area”. The main functions performed by rural areas are outlined. The definition of the concept of “rural areas” lacks functionality, i.e. the possibility to use it for the needs not only in various branches of the economy but also in social and ecological spheres in order to develop concepts for the development of rural areas and their management mechanisms. Therefore, the article suggests the following definition of the category “rural areas”: rural areas are a complex multifaceted socio-economic system characterized by autonomy, integrity, and sustainable development, which performs production, spatial-communication, socio-demographic, cultural-ethnic, recreational, political, and ecological functions, develops in space and time, is outside urbanized centers, and is under the management of local governments, state authorities, public organizations, and business structures.
Modern realities of compliance with ESG principles in the activities of corporations
Authors: Chervinska Oksana S. , Blavt Anna A.
Published: April 2024

Compliance with ESG principles is the modern narrative in the activity of domestic corporations, despite the destructive influence of Russian military aggression. Compliance with ESG principles, which in line with the goals of sustainable development, is a factor in reducing risks, building reputation, and making quality investment decisions. The article emphasizes that the compliance with ESG principles in the activities of corporations under martial law contributes to solving the tasks of environmental programs, nature conservation projects, ensuring the safety of production, and combating climate risks and the consequences of ecocide caused by the aggression of the Russian Federation on the territory of Ukraine. The war in Ukraine accelerated the “green transition” to reduce the specific weight of Russian energy imports. Compliance with ESG principles encourages Ukrainian corporations to modernize existing production from the point of view of environmental impact, despite the long-term military aggression of the Russian Federation. At the same time, corporations complying with the ESG principles in their activities implement social protection of employees, ensuring their well-being. Thus, under martial law, the probationary period for employment was abolished, especially for internally displaced persons. With martial law, the length of working time and rest time also changed. The socially responsible vector of enterprise development, as a component of compliance with the ESG principles, is now becoming the main long-term investment strategy. Management standards of ESG principles, such as anti-corruption measures, tax transparency, and undisguised decision-making methods of the board of directors, are gaining special importance in domestic realities. In general, compliance with ESG principles in the activities of corporations is the basis for obtaining several advantages, especially under martial law, when, despite the war, the main requirements of investors are focused on this aspect, along with the process of ensuring stable economic growth.
Scientific approaches to studying the system of economic security of an enterprise
Authors: Pravdyvets Oleksandr M.
Published: April 2024

The article considers the basic scientific principles and defines the main scientific approaches to the methodology of studying the economic security systems of enterprises, which include systemic, structural, functional, process, integrated, organizational-scientific, and resource-functional approaches. The author reveals that the integration of these approaches allows for a deeper understanding of the mechanisms of functioning and development of economic security of enterprises at different levels. Specific scientific approaches inherent in the development of the methodological foundations of security science are characterized, including defensive, competitive, harmonized, convergent, dynamic, adaptive, activity-based, reactive-situational, and resilient approaches. The article proves that this methodology has a significant scientific basis presented in numerous works that analyze in detail the phenomenon of economic security at different levels – from the state and regions to individual organizations. The author finds that the issues of security science are undergoing significant transformations, which are determined by changes in the external and internal environment of enterprises in the context of increasing turbulence and dynamics. These changes cause a constant need to analyze, improve, and develop new approaches, mechanisms, and tools to effectively respond to new threats and challenges. The article proves that the current conditions of informatization and digitalization require the inclusion of new information and technological foundations in the methodological apparatus, which expands the possibilities and methods of cognition. It determines that the synthesis of various scientific approaches and principles creates a conceptually new basis for security science, which reflects the need for a comprehensive and in-depth analysis of the economic security of enterprises, taking into account their interaction with various economic, social, political, and technological systems. The author proves that such an approach allows not only to analyze existing conditions and threats in depth but also to predict potential challenges and develop effective strategies for sustainability and development.
Benefit of noninvasive vagus nerve stimulation in vaccine optimization for young children
Authors: Rangon Claire-Marie , Staats Peter
Published: April 2024

Whether it is mandatory to vaccinate young children against SARS-CoV-2 and respiratory syncytial virus (RSV) is still an ongoing topic of debate. Indeed, vaccine acceptance for young children is either too low (in the case of COVID-19) or, in some cases, unattainable (with the demand far exceeding the capacity of production in the case of RSV vaccines in some countries). In addition, while vaccines do confer immunity, they can be complicated by inflammatory reactions to the vaccine itself. This inflammatory response is controlled by the nervous system, specifically the vagus nerve. Vagal tone optimization in and of itself confers some level of protection against viral infections such as SARS-CoV-2 or RSV, but the degree of protection has not been adequately evaluated. Even though additional studies are needed to validate a strategy of vagal optimization as an alternative to or co-treatment with vaccines, studies of noninvasive vagus nerve stimulation should be supported by public health agencies as an adjunctive tool providing young children with safe, ready-to-use immunization and protection from vaccine reactions. This recommendation is based on scientific, epidemiological, ethical, and economic considerations.
Clinical studies with drugs and biologics aimed at slowing or reversing normal aging processes—emerging results and future perspectives
Authors: Garay Ricardo P.
Published: April 2024

Five families of investigational products are in clinical investigation to slow or reverse normal aging processes [longevity candidates, mesenchymal stem cells, senolytics drugs, sirtuin activators, and nicotinamide adenine dinucleotide (NAD)+ precursors]. The longevity candidates, vitamin D and metformin, appear to significantly reduce all-cause mortality and prolong life expectancy. This should be confirmed by interventional studies. The mesenchymal stem cell family is the most advanced in clinical trial development [phase 2b randomized controlled trial (RCT)]. An allogeneic bone marrow stem cell preparation (Lomecel-B) reduced locomotor frailty in older people. The improvement in locomotion was modest. In the future, attempts could be made to improve potency through a precondition or genetic modification of naive bone marrow stem cells. Autologous adipose stem cell-assisted fat grafting increased graft survival, facial volume, and skin quality. The association of the senolytic drugs dasatinib and quercetin was well tolerated, with low brain penetration of dasatinib and undetectable levels of quercetin. The sirtuin-1 activator resveratrol (combined with physical exercise) improved physical function in older adults with physical limitations. The NAD+ precursor nicotinamide riboside improved physical exercise performance. In conclusion, Lomecel-B is the most advanced agent in clinical trial development for normal aging processes (phase 2b for locomotion frailty), followed by resveratrol and nicotinamide riboside.

Authors: M. Manogna , Reddy B. Amarendra , Kottala Padma
Published: April 2024

Many power electronic systems applications namely locomotives, hybrid electric vehicles, and all renewable energy sourced systems are shifting towards Multi-Input Multi-Output (MIMO) integrated DC-DC converters due to their reliability and flexible nature. Designing controllers for MIMO integrated DC-DC converter is complicated due to its integrated structure, presence of common elements, and interactions between the input and output variables of the converter. In this work, a Three-Input Integrated DC-DC (TIID) converter is modeled using state-space analysis, and a Transfer Function Matrix (TFM) is acquired from the small signal continuous time model. A robust controller based on the loop shaping method is designed for the TIID converter. In this loop-shaping method, the desired robustness and the performance of the controller are represented with weight functions i.e., loop-shaping filters. These weight functions are designed using TFM and are frequency-dependent. The robustness of the controller depends on the weight function parameters. The effect of varying the parameters of the weight functions on system dynamics, robustness, and performance are studied and plotted. TIID converter of 288 W, 24V-30V-36V to 48 V is considered and the impact of weight function on closed-loop system dynamics and sensitivity characteristics under varying parameter conditions are analyzed in MATLAB Environment.
Free vibrations of variablesection beams taking rotational and frictional forces into account
Authors: Baragunova L. A. , Shogenova M. M. , Shogenov O. M. , Yafaunov E. A.
Published: April 2024

Introduction. Beams are widely used in the construction industry as load-bearing structures of bridges, overpasses, coverings, slabs, stairs, equipment platforms, etc. In order to fully utilize the bearing capacity of such structures and to reduce the rate of material consumption, beams of variable cross-section along the length can be used. During operation, such structural elements are subjected to various types of vibrations, which determines the relevance of studying various aspects of vibrational motion.

Aim. To apply numerical methods for studying the influence of rotational inertial forces in the presence of viscous frictional forces on free vibrations of variable-section beams. This area of research presents interest, since the calculations are directly related to the determination of frequencies and forms of natural vibrations of structures.

Materials and methods. Free vibrations were described by a homogeneous partial differential equation of hyperbolic type. The methods of variable separation and finite differences were used. A discrete domain in the form of a set of uniform grid nodes and a homogeneous system of algebraic equations were introduced. The system of equations in the matrix-vector form was used.

Results. The spectra of natural frequencies, damping coefficients, and eigenforms of beam vibrations are determined. It is shown that the coefficient matrix has a banded and pentadiagonal form. The matrix elements are functions of the characteristic index. The damping coefficient and the frequency of free vibrations are determined from a system of two nonlinear equations. The solution of the system of equations is found using the method of coordinate descent. An example of calculation of a welded I-beam is considered. Five elements of the spectra of damping coefficients and natural frequencies are calculated.

Conclusions. State-of-the-art MATLAB solvers allows numerical and graphical methods to be combined. In the solved examples, the advantages of these methods were successfully applied to determine the eigenvalues of matrices and eigenfunctions. The high validity and accuracy of the results obtained confirm the simplicity and versatility of the methodology for determining the characteristics of free vibrations of beams of variable cross-section.

Insect attachment on waxy plant surfaces: the effect of pad contamination by different waxes
Authors: Gorb Elena V , Gorb Stanislav N
Published: April 2024

This study focuses on experimental testing of the contamination hypothesis and examines how the contamination of insect adhesive pads with three-dimensional epicuticular waxes of different plant species contributes to the reduction of insect attachment. We measured traction forces of tethered Chrysolina fastuosa male beetles having hairy adhesive pads on nine wax-bearing plant surfaces differing in both shape and dimensions of the wax structures and examined insect adhesive organs after they have contacted waxy substrates. For comparison, we performed the experiments with the same beetle individuals on a clean glass sample just before (gl1) and immediately after (gl2) the test on a plant surface. The tested insects showed a strong reduction of the maximum traction force on all waxy plant surfaces compared to the reference experiment on glass (gl1). After beetles have walked on waxy plant substrates, their adhesive pads were contaminated with wax material, however, to different extents depending on the plant species. The insects demonstrated significantly lower values of both the maximum traction force and the first peak of the traction force and needed significantly longer time to reach the maximum force value in the gl2 test than in the gl1 test. These effects were especially pronounced in cases of the plant surfaces covered with wax projections having higher aspect ratios. The data obtained clearly indicated the impact of waxy plant surfaces on the insect ability to subsequently attach to the clean smooth surface. This effect is caused by the contamination of adhesive pads and experimentally supports the contamination hypothesis.

Published: April 2024

En el presente texto se pretende mostrar, desde una perspectiva crítica, la inadecuación de algunos discursos y narrativas propias de la política educativa al contrastarlas con la realidad social del sistema educativo mexicano. La metodología utilizada es la investigación documental, así como el análisis del discurso de diversas autoridades en el ámbito educativo. La educación está inmersa en una dinámica sociocultural, por lo que el énfasis del trabajo está puesto en las representaciones sociales y lo significados que están implícitos en los discursos y documentos oficiales. A la vez, se pretende contrastar la situación nacional con la Agenda 2030 de la ONU, esencialmente con aquellos Objetivos de Desarrollo Sostenible que se relacionan con la educación. Se muestra el contundente divorcio entre el discurso y los resultados, así como las realidades educativas de los profesores y estudiantes. La intención, por tanto, es favorecer el pensamiento crítico y analítico ante la educación, para no reaccionar de manera sumisa a todos los discursos tranquilizadores y centrados en falacias que están vertidos en la cotidianidad de la política educativa nacional e internacional.

Published: April 2024

El retraso de infraestructura, la contaminación de los cuerpos de agua, reducción del número de fuentes disponibles, el costo de agua apta para consumo humano y el cambio climático son de los problemas ambientales más graves al que se enfrenta la humanidad en la actualidad, la atmósfera no tiene fronteras, no puede detenerse “a voluntad”. Cepal, 2012 estima que menos del 10% de aguas residuales son tratadas antes de ser devueltas al cuerpo receptor, más del 90% de cuerpos de agua están siendo contaminados en la región centroamericana. La temperatura es uno de los parámetros físicos más importantes en el agua, influye en el retardo o aceleración de la actividad biológica. Es importante desarrollar y construir tecnologías, que contribuyan con la reducción de GEI y saneamiento, contribuyendo a la mitigación del cambio climático, como por ejemplo con una planta macrófita(E. Crassipes) que puede ser utilizada para absorber nitrógeno y fósforo a diferentes temperaturas medias máximas dentro de un tanque con aguas residuales. Los resultados obtenidos con E. Crassipes indican la capacidad significativa para absorber nitrógeno y fósforo en diferentes temperaturas. A medida que la temperatura varía, esta capacidad puede ser afectada, pero su capacidad fitodepuradora sigue siendo significativa.  Es por ello que se determinó que el aporte de una planta macrófica como lo es la E. Crassipes en los sistemas de tratamiento para mitigar el cambio climático,  tratando las aguas residuales domésticas con soluciones basadas en la naturaleza, ante el probable aumento de las temperaturas es eficiente y muy significativo.

Published: April 2024

Políticas públicas são frequentemente desafiadas por alterações nas condições de sustentação e nos regramentos para sua operacionalidade. Quando crises irrompem, as políticas são imediatamente afetadas e muitas delas perdem sua validade operativa. Neste capítulo, discutimos como a confluência de crises econômicas, políticas, sanitárias e o imperativo ambiental da mudança climática nas últimas duas décadas têm desorganizado o plano político-institucional em que se assentam as políticas públicas. Nesses momentos de ruptura de padrões, surgem, entretanto, ideias, projetos e esforços para reavaliação e retomada das políticas em novos termos. A política regional brasileira não foge à regra, podendo ser repensada para oferecer saídas adequadas para as transformações em curso.

Diante de sua importância e pluralidade, trata-se de um conceito que impõe desafios para ser abordado.
ACTUALIZING THE VENTURING MODEL IN UKRAINE
Authors: Yereshko Julia , Kreidych Iryna , Kravchenko Maryna , Kazak Oksana , Kharchenko Оleksandr
Published: April 2024

The financing of innovations is the driving driver of the innovative model of development of any country, and Ukraine in particular. In modern conditions, the importance of venture capital for the economy of Ukraine is growing against the background of reducing alternatives to raising capital for the development of small and high-tech businesses. The reasons for the current state of decline in the innovation and investment process in Ukraine are analyzed and identified. Peculiarities of venture investment in Ukraine are studied. It is determined that the vast majority of venture capital institutions, regardless of their field of activity, are used mainly by large industrial and financial groups to preserve assets and minimize taxation, rather than to finance innovation. The obtained results give grounds for the conclusion that the essence of venture entrepreneurship in Ukraine does not correspond to the American and European models. The current conditions turn venture funds in Ukraine from an instrument of innovative development into a means of making a profit for large financial and industrial groups, which is a hidden reason for slowing down the innovation and investment process. An updated Ukrainian venture model is proposed, taking into account the peculiarities of the economy and a thorough rethinking of the existing structure of venture capital. The introduction of a rational combination of public, private, and research components of the investment process is proposed, i.e. the need to involve universities, scientists, and the scientific elite in the venture industry. It is determined that this model is only one of the components of a comprehensive program to stimulate investment demand, which also includes: ensuring macroeconomic stability; ensuring economic freedom; ensuring economic security; an increase of investment resource; impact on investment propensity; liberalization and development of the financial market; stimulating investment activities through the mechanism of state support for business and science partnerships.

To this end, we revised, adapted and expanded existing metadata schemas, vocabularies and thesauri to build a FAIR metadata schema and a metadata entry form built on it for users to provide their metadata instances focused on biodiversity monitoring data. The schema is FAIR because it is both machine-interpretable and follows domain-relevant community standards. This report provides a general overview of the project results and instructions on how to access, re-use and complete the metadata form.

Atractilina Dearn. & Barthol. and Spiropes Cif. are genera of asexual fungi that comprise species mainly hyperparasitic on black mildews (Meliolales, Ascomycota). Although a common group of anamorphic fungi, they have been described up to now only by morphology and their systematic position is unknown. The present study provides a morphological treatise of all known species of Atractilina and Spiropes hyperparasitic on Meliolales, including insights into their systematic position, based on DNA sequences generated here for the first time. The study was conducted, based on 33 herbarium specimens and 23 specimens recently collected in Benin and Panama. The obtained DNA sequence data (28S rDNA and ITS rDNA) of A. parasitica and of two species of Spiropes show systematic placements in the Dothideomycetes and Leotiomycetes, respectively. The sequence data of the two Spiropes spp. do not group together. Moreover, the anamorph-teleomorph connection between Atractilina parasitica and Malacaria meliolicola, a pseudothecioid fungus, is confirmed. Three species in the genus Spiropes are proposed as new to science, namely S. angylocalycis, S. carpolobiae and S. croissantiformis. Four species are reported for Benin for the first time, three species for Panama and one species for mainland America. Atractilina and Spiropes are currently two genera with highly heterogeneous species and they might have to be split in the future, once the taxonomic concepts are validated by morphology and molecular sequence data.

L’arrêt du 27 février 2019 de la Cour d’appel de Bruxelles b doit retenir toute notre attention. Il a été rendu à l’encontre d’un entrepreneur en construction dont le manquement répété et persistant à ses obligations de sécurité et de protection de ses travailleurs a finalement mené au décès accidentel de l’un d’eux.
La limite des 80 % sous les fourches caudines du fisc
Authors: Mariscal Bernard
Published: April 2024

Le respect de la limite des 80 % est une condition de déduction essentielle des primes d’une pension complémentaire. Sous prétexte d’abus, elle fait l’objet d’attaques sans précédent de la part du fisc. La présente contribution entend faire une analyse critique de ces attaques souvent injustifiées.
Assurance R.C. vie privée
Authors: Rondao Alface Anthony
Published: April 2024

Un mineur de 12 ans effectue une marche arrière non autorisée avec un véhicule sur un parking et heurte un véhicule en stationnement. Pendant ces quelques secondes, son oncle, qui le gardait, avait été ranger le caddie, à quelques mètres de là. Il avait laissé l’enfant seul dans le véhicule. Cela engendre-t-il l’application de la clause joyriding de l’assurance R.C. vie privée des parents ou s’agit-il plutôt d’un défaut de surveillance dans le chef de l’oncle qui avait la garde du mineur ?
L’appropriation discursive de la parole de la femme. Le cas des fatwas
Authors: Benidir Faïza
Published: April 2024

Dans la perspective d’observer ce qu’il se passe, d’un point de vue linguistique, quand des « hommes » parlent à la place des « femmes » sur des sujets qui les concernent directement, cet article tente d’explorer les enjeux du procédé énonciatif de « parler à la place des autres » (Paveau 2016). Ici, il est abordé le contexte de domination rattaché à l’activité de l’émission des avis juridico-religieux musulmans (les  fatwas ) lorsqu’elle est menée exclusivement par des mouftis hommes dans le cadre de la discussion des questions qui concernent spécifiquement les femmes. L’objectif de cet article est d’exposer comment la prise de parole des hommes à la place des femmes est, malgré son objectivité et neutralité axiologique postulées, imprégnée de connotations culturelles, de projections d’imaginaires et d’intégration de stéréotypes en rapport avec la femme et contribue à véhiculer celles-ci. Il montre que dans certaines  fatwas la parole des femmes est en quelques sorte détournée ou déjouée pour faire valoir la position de l’autorité religieuse, représentée par le moufti.
Multi-Local-Worlds economic and management complex adaptive system with agent behavior and local configuration
Authors: Zhang Hebing , Zheng Xiaojing
Published: April 2024

The central focus of our investigation revolved around the convergence of agents' behavior toward a particular invariant distribution and determining the characteristics of the optimal strategies' distribution within the framework of a dynamical Multi-Local-Worlds complex adaptive system. This system was characterized by the co-evolution of agent behavior and local topological configuration. The study established a representation of an agent's behavior and local graphic topology configuration to elucidate the interaction dynamics within this dynamical context. As an illustrative example, we introduced three distinct agent types—smart agent, normal agent, and stupid agent—each associated with specific behaviors. The findings underscored that an agent's decision-making process was influenced by the evolution of random complex networks driven by preferential attachment, coupled with a volatility mechanism linked to its payment—a dynamic that propels the evolution of the complex adaptive system. Through simulation, we drew a conclusive observation that even when considering irrational behaviors characterized by limited information and memory constraints, the system's state converges to a specific attractor. This underscored the robustness and convergence properties inherent in the dynamical Multi-Local-Worlds complex adaptive system under scrutiny.
Skeleton action recognition via graph convolutional network with self-attention module
Authors: Li Min , Chen Ke , Bai Yunqing , Pei Jihong
Published: April 2024

Skeleton-based action recognition is an important but challenging task in the study of video understanding and human-computer interaction. However, existing methods suffer from two deficiencies. On the one hand, most methods usually involve manually designed convolution kernel which cannot capture spatial-temporal joint dependencies of complex regions. On the other hand, some methods just use the self-attention mechanism, ignoring its theoretical explanation. In this paper, we proposed a unified spatio-temporal graph convolutional network with a self-attention mechanism (SA-GCN) for low-quality motion video data with fixed viewing angle. SA-GCN can extract features efficiently by learning weights between joint points of different scales. Specifically, the proposed self-attention mechanism is end-to-end with mapping strategy for different nodes, which not only characterizes the multi-scale dependencies of joints, but also integrates the structural features of the graph and an ability of self-learning fusion features. Moreover, the attention mechanism proposed in this paper can be theoretically explained by GCN to some extent, which is usually not considered in most existing models. Extensive experiments on two widely used datasets, NTU-60 RGB+D and NTU-120 RGB+D, demonstrated that SA-GCN significantly outperforms a series of existing mainstream approaches in terms of accuracy.
