Authors: Tóth Gitta , Kucséber László , Pollák Zoltán , Jáki Erika
Published: November 2024

The aim of our research is to fill the research gap on how successful businesses have been affected by the challenges posed by COVID-19 regarding the resilience and adaptability of firms. Since 2016, the Budapest Stock Exchange (BSE), with the collaboration of EY, selects a number of unlisted companies (BSE50) per year that have Hungarian roots and are considered successful based on their operations and ability to increase sales. We examined the impact of COVID-19 on profitability, liquidity, indebtedness and change in turnover or EBITDA based on four years (2018–2021) of financial data from 252 non-financial, unlisted companies. In addition to the descriptive statistics, a two-sample asymptotic z-test was used to compare the periods before and during COVID-19. We divided the BSE50 companies into Dynamics and Laggards based on the change in turnover between 2019 and 2020. The Dynamics of the pandemic have emerged from the challenging period of COVID-19 as real champions, taking advantage of their low level of indebtedness by making efficient use of loan possibilities. Even the Laggards were able to rebalance and consolidate their financial position by the second year of the pandemic. Our study is novel because we used data on Hungarian, non-financial, unlisted companies with successful management to examine the impact of COVID-19 on hard-hit firms as well as on firms in the winning branch.

In this work, the Quality Function Deployment (QFD) and Failure Mode and Effects Analysis (FMEA) methodology based on the «Design for X» concept is studied to define the design criteria of the mechanical characteristics of an EOD robot and validated with a virtual prototype of an Explosive Ordnance Disposal (EOD) robot. The objective is the application of this methodology to obtain a product that meets the quality and reliability specifications, considering the user’s needs as input data. To validate this methodology, the technicians of the UDEX (Explosive Ordnance Disposal Unit), the mechanical characteristics of the previous version JVC 0.2 developed by the research team of the National University of San Agustin (UNSA), the minimum specifications of the robots participating in the League of Rescue Robots and the application to work in real environments were taken as a case study. The results indicate that the application of the proposed methodology has significantly improved the quality and reliability of the design. To validate the effectiveness of this methodology, a virtual prototype, called JVC 0.3, was created using SolidWorks modelling software, a significant weight reduction of 27.13 % was achieved and the operating speed was increased to 1 km/h under optimal conditions. Technical analysis of the JVC 0.3 showed significant improvements in several key areas, such as increased modularity for easier assembly and maintenance, decreased overall weight, increased torque and speed, and increased stability during operation. These factors are essential for the practical application of EOD robots in real field operations carried out by specialized units such as UDEX

Published: November 2024

In this study, a large-scale magnetic rotator for hydrogen production boosting was designed. The study addresses the challenge of selecting and designing mechanical components for a dynamic magnetic field (DMF) magnetic rotator in a green hydrogen electrolysis power plant, focusing on ensuring component reliability and efficiency under operational stresses. The aim is to determine suitable machine element materials (shaft, clutch, gears, etc.), allowable shear stress, and interconnection mechanisms through theoretical and practical evaluations. The method includes calculating the allowable shear stress for the spline based on carbon steel tensile strength, applying safety factors for material properties and load considerations, and determining shaft diameter using torque and shock load factors. Standard catalogs guide the selection of interconnections like clutches, gears, and bearings to ensure compatibility and performance. The results indicate that a 95 mm diameter S30C carbon steel shaft, with an allowable shear stress of 7.8 kg/mm2, meets the design requirements. The chosen spline dimensions and a 12.5 MW, 14-pole induction motor align with the system’s needs, ensuring reliable operation. The discussion highlights the critical balance between theoretical predictions and practical application in design optimization. It underscores the importance of incorporating safety factors and verifying component suitability to ensure robust performance of the magnetic rotator. This study provides a comprehensive approach to design optimization, integrating theoretical analysis with practical considerations to achieve optimal performance and reliability. The design output of this study can be used to boost the hydrogen evolution reaction in the SIEMENS Sylizer 300 electrolysis cell.

Published: November 2024

MIMO (Multiple Input Multiple Output) makes a major contribution to 5G communication systems by increasing network capacity and spectrum efficiency. In 5G, MIMO enables the use of multiple antennas at base stations and user devices, allowing simultaneous sending and receiving of data over multiple paths. This significantly increases data throughput and connection reliability, especially in environments with high user density. In addition, MIMO technology supports the implementation of beamforming, which focuses signals on a specific direction, reduces interference, and improves signal coverage and quality, making it one of the keys to achieving faster and more responsive 5G performance. Therefore, antennas with wide bandwidth, high gain and MIMO performance are crucial for supporting 5G communication systems. This paper proposes a high-performance MIMO microstrip antenna based on a series planar array with 8×2 elements operating at a resonant frequency of 3.5 GHz for 5G communication systems. A spiral stub and a feed inset are proposed to control the reflection coefficient and bandwidth of the antenna while the series planar array is proposed to increase the gain. To support the MIMO communication system, the proposed antenna is separated into two different ports with a certain distance. From the measurement results, the proposed antenna has high performance indicated by a wide bandwidth of 680 MHz (3–3.68 GHz) and a high gain of 17.8 dB at a resonant frequency of 3.5 GHz. In addition, the proposed antenna has high mutual coupling and diversity indicated by ECC and DG of 0.001 and 9.99 dB, respectively. This work provides a solution to design a high-performance microstrip antenna and can be implemented as a receiving antenna for 5G communication systems

This research focuses on optimizing ultra-wideband (UWB) antennas, which are critical in modern communication systems due to their wide frequency range (3.1–10.6 GHz) and high data transmission capabilities. The study addresses the challenge of optimizing key antenna parameters – such as return loss, peak gain, and radiation efficiency – while also ensuring energy efficiency and network longevity. Traditional optimization methods, such as LEACH-C, often fail to balance these factors, leading to suboptimal performance.
To solve this problem, the researchers developed the Generalized Position-based Optimization Neural Network (GPON) for UWB antenna optimization. They also evaluated the Position-based Hybrid Neural Network (PAN) method, comparing its performance with existing algorithms including LEACH-C, Firefly Algorithm (FA), HFAPSO, FA-ANN, and HWOABCA. The GPON model reduced return loss to 25.5 dB at 3.5 GHz and improved peak gain to 4.2 dB i, while maintaining 92 % radiation efficiency. In contrast, PAN demonstrated a 15–25 % improvement in residual energy and extended network lifetime by 20 % compared to LEACH-C.
These improvements were due to the integration of advanced neural network techniques in GPON and the effective use of positional data in PAN, enabling more precise and adaptive optimization. The ability to balance multiple performance metrics simultaneously – a challenge previous models struggled with – is a key feature. This balance is crucial for UWB antennas in communication systems where both performance and energy efficiency are vital. The findings are especially relevant for practical applications in wireless sensor networks, mobile communications, and radar systems, requiring long-term network reliability and optimal antenna performance

The object of this study is the process of strip tillage, its effect on soil moisture in the strip, and subsequent vegetation of sunflower plants. At the same time, the task to increase the efficiency of strip tillage was solved.
It has been established that the rational values of the structural and technological parameters of the strip tillage section in terms of fuel consumption depend on the speed of movement of the unit, the depth and width of the tilled strip of soil. One section of the unit was used for the research. The studies were conducted using the Box-Benkin three-factor experiment design. It was established that the rational values of the structural and technological parameters of strip tillage in terms of fuel consumption have the following values: the depth of strip tillage h=20‒25 cm, the width of strip tillage b=20‒25 cm, the speed of the unit from 7.5 to 11 km/hours. In this case, the actual fuel consumption ranged from 4.2 to 6.3 l/ha.
It was also established that an increase in the width and depth of the strip cultivation leads to an increase in moisture loss in it. The highest value of soil moisture occurs at the minimum values of the depth and width of the strip cultivation, and the lowest at their maximum values. The influence of the width of the cultivated strip on the height of sunflower plants is more significant than the influence of the depth of tillage. This applies both to the range of changes in the height of sunflower plants (12.4‒13.6 cm compared to 12.5‒13.1 cm) and the intensity of the impact. The greatest influence on the height of sunflower plants is exerted by the magnitude of the transverse displacement of the axis of the row of plants. The intensity of this influence is approximately the same as the depth of tillage, and the range of changes in the height of sunflower plants is 11.7‒14 cm.
Research results could be used in the design of units for strip tillage and sowing units.

The object of this study is the processes of shielding electromagnetic radiation by building and facing materials. The research is aimed at solving the problem of ensuring the electromagnetic safety of people by improving the composition and structures of building and facing materials.
Means for improving the electromagnetic safety of people under industrial and domestic conditions using non-homogeneous building materials have been determined. The shielding properties of reinforced concrete structures were studied. A methodology for increasing their efficiency depending on the amplitude-frequency characteristics of the radiation that needs shielding has been devised. The efficiency of electromagnetic radiation shielding by heterogeneous dielectric building materials based on cement concrete and basalt fibers was determined. It was established that shielding through the refraction of electromagnetic waves on inhomogeneities does not give an acceptable effect. The expediency of covering basalt fibers with a conductive substance to increase the protective properties of materials was substantiated. The protective properties of flat facing material with carbonyl iron content were studied. It has been shown that the properties of materials can be effectively controlled by adjusting the filler. The material's transmission coefficient of ultra-high frequency electromagnetic radiation does not exceed 0.40, and the reflection coefficient – 0.25 with a filler content in the base of 14–15 % by volume. This makes it possible to simultaneously ensure the electromagnetic safety of people and the stable functioning of wireless communication devices. The advantage of the material is the low coefficients of reflection of electromagnetic waves, which does not lead to deterioration of the electromagnetic situation in other areas where people stay. It has been established that the addition of boron nitride to the facing material significantly increases the thermal insulation characteristics of the coating and contributes to the solution of energy saving problems. Adding a layer containing boron nitride to the material provides thermal conductivity coefficients of 0.030–0.031 W/m·K, which is better than known analogs

Brantas River experiences significant pollution due to domestic and industrial wastes. This condition also causes natural disasters such as floods. Single use plastics generally made up a large portion of local wastes. However, previous studies mostly investigated plastic waste pollution and local waste management habits as separate topics. Therefore, the objects of this study are the plastic wastes in Brantas River, as microplastic particles, and the identification of its source. The assessments were based on microplastic counts, macroinvertebrate bioassessment with SIGNAL-2 index, and the quantitative data of local domestic waste management at three Stations in Malang City area. Riverine microplastic pollutant concentrations and its sources were both successfully identified and solved. The results showed that the highest riverine microplastic particles were found in Station 3. This station only had four macroinvertebrate taxa with a SIGNAL-2 score of 4.42, indicating severe degradation. Quantitative data showed that 80 % of Station 3 residents threw plastic wastes directly to Brantas River. The low macroinvertebrate counts possibly caused by ingestion of microplastic from households and small-scale enterprises which heavily utilized single use plastics to trade their goods. The first distinctive feature of this study is the comparability of the microplastic, and macroinvertebrate counts with the river degradation status. Secondly, the quantitative data can serve as complementary evidence. Practically, the obtained results can be developed into an integrated plastic waste management plan for the residents surrounding the rivers, particularly in developing countries with similar socio-cultural conditions as elaborated in this study, to maintain the ecosystem quality
Assessing the potential accuracy of a small-sized goniometer with extended dynamic range based on nuclear magnetic resonance
Authors: Ivanov Sergiy
Published: November 2024

This paper evaluates potential accuracy characteristics of a small-sized goniometer based on nuclear magnetic resonance with an extended dynamic range. This required constructing a model of goniometer errors, estimating its accuracy based on this model, and formulating practical recommendations for the design of such a device based on the accuracy assessment.
To evaluate the accuracy of a nuclear goniometer, a theoretical model was built  that makes it possible to determine the optimal operating parameters of the cell gas mixture, the ranges of their permissible changes, the sensitivity of the goniometer, and the dependence of its characteristics on external and internal factors. In particular, the dependence of output signal of the device on the parameters of gas mixture and optical pumping has been determined. For a goniometer with a cell volume of 8 cm3, the optimum temperature is 130 °C, and the optimum intensity of the pumping radiation is 5 mW.
The dependence of output signal on the measured angle of rotation was also established, as well as the noise and error dependence of the device on the permissible values of its parameters. Based on the model built, parameters of a goniometer with a cell volume of 8 cm3 were determined; the maximum angular sensitivity of such a goniometer with complete suppression of technical noise is δφsen=1.0 arcsec. The greatest contribution to the angle measurement error is from the instability of pumping power Ip (ΔIp/Ip=0.05) – 85 %, magnetic field B0 (ΔB0/B0=10-8) – 13 %, temperature T (ΔT/T=0,1) – 2 %.
The goniometer under consideration corresponds to the medium accuracy class, δφtot≥10 arcsec. It could be used in optical manufacturing for operational control, calibration, and certification of optical products. To improve the angular accuracy of the goniometer, it is necessary to increase the stability of the laser pumping intensity

Published: November 2024

The object of this study is the theoretical and methodological approaches to determining the coefficient of moisture conductivity of subgrade soils. The work focuses on considering the European approaches and standards when devising a method for determining the coefficient of moisture conductivity of soils.
In the course of the research, a method was developed for determining the coefficient of moisture conductivity of soils K1, which characterizes the diffusion movement of water, through the filtration coefficient K0, calculated in accordance with European requirements based on laboratory test data.
The proposed method is based on a mathematical model built on the basis of the differential equation of changes in soil moisture. The model is special in that, unlike existing ones, the movement of water was modeled from the bottom up, which reflects the process of moisture accumulation in the lower layers of the subgrade from groundwater or topwater.
A good agreement of the mathematical model with the data by other authors was obtained (the relative error did not exceed 12.98 %).
A direct relationship between the moisture conductivity coefficient of soils K1 and their initial moisture content W0 and an inverse relationship between K1 and the total moisture capacity of soils WFH were established in the paper. Dependences were derived in the range of changes in initial soil moisture W0 from 0.08 to 0.15 and WFH from 0.15 to 0.5. It was found that the values of the moisture conductivity coefficient of soils K1 increase from 4.64·10-6 to 3.81·10-5 m2/h with an increase in their initial moisture content and with a decrease in total moisture capacity.
From the point of view of engineering practice of road construction, the proposed method makes it possible to predict seasonal changes in soil moisture in the subgrade, to determine the strength of the road structure. This makes it possible to make sound design decisions on the installation of drainage systems on roads in order to extend their service life

Pharyngealization in Tashlhiyt from kinematic and acoustic perspectives
Authors: Buech Philipp , Hermes Anne , Ridouane Rachid
Published: November 2024

This study investigated the implementation of pharyngealization in Tashlhiyt, across various linguistic contexts VCV, VCCV, VCCV, and VCCCV. We analyzed articulatory and acoustic data from six male speakers who produced real words containing these sequences with both plain ([d, z]) and pharyngealized target consonants ([dˤ, zˤ]). The investigation comprised dynamic analyses of kinematic and formant trajectories, as well as acoustic parameters of consonants and intrusive schwas. While pharyngealization did not affect the tongue tip, it did lead to a significant lowering of the tongue body. This lowering was not confined solely to the target consonants but was observed in larger domains, extending up to nearly the entire VCCCV items. The primary acoustic correlate of pharyngealization was identified as a lowered F2 of vowels and intrusive schwas, while acoustic properties of consonants remained unaffected. Consistent with observations in the articulatory domain, the lowering of F2 was not restricted solely to vowels adjacent to pharyngealized coronals; instead, it extended to larger domains, even when there were intervening consonants.

Published: November 2024

The results of phenological observations of 139 species of perennial plants in the NEFU Botanical Garden are presented. According to the timing of flowering, spring (20% of species), early summer (48%), summer (27%) and late summer (5%) phenological groups of plants were distinguished. The number of flowering species in the collection increases as the daytime temperature rises to +25°C. The greatest shifts in the timing of the onset of flowering are typical for summer and late summer plants. Steppe plants respond well to cultural conditions; 92% of introduced plants go through a full cycle of shoot development, bear fruit annually, and 86% increase the size of their populations through seed or vegetative self-renewal. Late flowering species are less resistant.

was found that a typical strain and genovariants of Vibrio cholerae O1 when cultured in AKI medium at different growth stages release outer membrane vesicles into the environment. Preparations of vesicles were obtained by ammonium sulfate precipitation and visualized by electron microscopy. Using monoclonal antibodies and polyclonal antitoxic conjugate, the presence of lipopolysaccharide and outer membrane proteins OmpU and OmpT, as well as cholera toxin in these structures was determined. On the model of cell culture of two cell lines CHO-K1 and HuTu 80 it was shown that in the presence of vesicles morphological changes of target cells characteristic for cholera toxin are observed. The results obtained suggest that the content of outer membrane vesicles depends on the stage of vibrio growth, and the biologically active substances produced by them are capable of causing cell damage, thereby provoking an inflammatory reaction of cells in the host organism.

Published: November 2024

In the extrusive-subvolcanic body of the acid composition of the Lyadgey Complex (λV2ld) of the southern part of the Enganepe Ridge, rhyolites with unusual textural and structural features are identified. Petrographic and mineralogical study of the thin-banded rhythmic structure and spherical forms in rhyolites revealed the genesis of these features. The presence of secondary changes in the form of sericite and chlorite, indicating a high content of fluids (water) in the rock, which lead to the delamination of the melt, and the natural differences in chemical compositions in rhyolites, allowed explaining this features by the processes of liquation.

The Turks Island Skink, Spondylurus turksae Hedges and Conn 2012, is endemic to the Turks Bank,Turks and Caicos Islands, at the southeastern terminus of the Lucayan Archipelago in the greater Caribbean region. AnInternational Union for the Conservation of Nature (IUCN) Red List Assessment provided strong evidence that thespecies’ range declined precipitously throughout the 20th century, and a status of Critically Endangered was assessedin 2016. While previously found on several of the Turks Islands, the species was not documented between 1972 and2008, when we discovered a new population on Cotton Cay. We report on the status of the Turks Island Skink basedon surveys of the Turks Cays from 2008 to 2022–2024. We found that the skink is likely restricted to a novel populationwe report on Cotton Cay and that this is possibly the only remaining population of the species, reinforcing itsstatus as Critically Endangered. We further provide the first published photographs of live individuals of the species.
Social self-determination and regional self-identification of students of the Trans-Baikal Territory

The article deals with the problem of social self-determination of student youth and the influence on this process of regional identification caused by the entry of the TransBaikal Territory into the Far Eastern Federal District. The authors present the results and conclusions of a questionnaire survey of students of Trans-Baikal universities conducted within the framework of a large-scale sociological project “Social Self-Determination of Youth in the Formation of a New Regional Identity (Based on the Materials of the TransBaikal Territory and the Republic of Buryatia)”. The project is based on the idea of the interrelation between two scientific categories – “regional identity” and “social selfdetermination”. Moreover, regional identity is considered not only as a traditionally and historically grounded territorial and cultural identification, but as an artificially created geographical, economically conditioned territorial reality, which originates from November 4, 2018, when the Trans-Baikal Territory and the Republic of Buryatia were transferred from the Siberian Federal District to the Far Eastern Federal District by the Decree of President Vladimir Putin. The authors understand social self-determination as the inclusion of a person in all spheres of society, a person’s awareness and achievement of a stable position in the system of social relations. The components of social self-determination of student youth were identified: socio-professional self-determination, socio-political self-determination and socio-cultural self-determination within the framework of the studied missile defense. The analysis of the survey results allowed the authors to determine: (1) the most typical professional and motivational profiles and strategies of professional self-determination of Trans-Baikal students; (2) political orientations and attitudes of Trans-Baikal student youth in socio-political self-determination; (3) value orientations and life position in socio-cultural self-determination. The authors used the method of “layer proximity” identifying the level of regional identification of students of Trans-Baikal universities. The analysis of the identification profiles of the interviewed students showed that the new regional reality (I am a Far Easterner), artificially created for certain state purposes, has not yet entered the consciousness of the student youth and is not perceived by them as “close” and “native”. But in fact this is a strategic level of regional identity associated with the construction of a new regional image, the positioning of a new territorial entity, the invention of new territorial traditions and the formation of a new symbolic policy.
Medieval moscow myth about the state and its semantic actualizations in modern time
Authors:   National Research Tomsk State University, Shcherbinina Nina G. , Avanesova Elena G. ,   National Research Tomsk State University
Published: November 2024

The medieval state in Rus’ was constituted and symbolized as a Christian institution, and its quintessence was the image of the sovereign. To fill the significant image with meaning, the mythological motif of serpent fighting, the struggle of the Hero with the Enemy, was used. This was demonstrated both by visual representations (icons, seals, coat of arms) and by the official nomination “tsar”, which acquired a special Orthodox mystical meaning. The sacralization of the image of the Russian sovereign and state was based on the Byzantine model of a universal empire, in which the tsar was the vicar of Christ on earth, being his “living” incarnation. As a result, the role of Moscow, this already transcendental state, called by virtue of symbolic continuity the “Third Rome”, and the tsar were associated with the extension of the life of the fourth world Christian kingdom in the context of the coming end of the world. This last kingdom, it was believed in medieval Moscow, was already an established Orthodox power, united in the universe, headed by a truly Orthodox tsar, hence the main political function of the tsar was to protect Orthodoxy from enemies. Thus, on the basis of the construction of the heroic myth, a complete and all-encompassing world of meaning was built, and the political order was legitimized in its ultimate meaning, in its correlation with the divine cosmic order. The ideas of Russian Orthodox theology of the 18th–20th centuries concerning what should be done in the construction of Russian statehood are based on ideas about the God’s chosenness of the Russian people, the religious mission of Rus’ and its tsar, formed during the period of the Principality of Moscow. Meanwhile, the theology of this period also has its own specifics. The new political reality, characterized by the fact that Russia, with the beginning of the church reform of Peter the Great, took the path of state secularization, gives a special tone to discussions about the nature of Russian statehood. The theological thought of this period is distinguished by an attempt to substantiate the need for a return to traditional values, which, according to the authors, constitute the basis of Russian statehood. Particular hope for a return to the “old models” rests with the Russian people, who are assigned a heroic role – to be the savior of the state. Ideas about the mystical nature of the Russian state are updated today through speeches and statements of political and religious leaders, in which political power is represented in mythical-heroic motifs, and Russia appears as a defender of traditional values and world Orthodoxy, a state with a messianic role in the modern world.
The logic of framing effects by Franz Berto and Aybüke Özgün as a new formalism for solving problems of semantics of propositional attitudes
Authors:   Russian Society for the History and Philosophy of Science, Moiseeva Anna Yu.
Published: November 2024

The article discusses the problems of formalizing the content of propositional attitudes and how successfully these problems can be solved in possible worlds semantics. The focus of attention is, firstly, on the phenomena that in the psychological literature are called framing effects and in the semantic literature substitution violation in indirect contexts, and, secondly, the problem of logical omniscience. The first part of the article explains why framing effects create a problem for possible worlds semantics and why the agent is inevitably modeled as logically omniscient in this semantics. Next, a description is given of four approaches to the problem of framing effects in possible worlds semantics: metasemantic, pragmatic, multi-model, and the approach associated with modeling topics. For each of the first three, their main shortcomings are given in relation to this problem and in general. The results of applying the latter approach are considered in more detail in the next part of the article using the example of one of the modern systems of doxastic logic, namely the logic of framing effects by Berto and Özgün. The syntax and semantic rules of this logic are outlined, after which it is explained how, according to these rules, the description of framing effects should look like. Models of situations are given in which an agent has both a belief in some proposition and a lack of belief in another proposition, which is necessarily equivalent to the first one. It is shown that the modeling method used does not lead to problems and is intuitively adequate. In the last part, the axiomatics of the logic of framing effects is presented and some theorems are given that are significant in the context of the problem of logical omniscience. An interpretation of these theorems is given, on the basis of which it is concluded that this logic does not cope with the problem of logical omniscience as successfully as with the framing effects themselves. In conclusion, a direction is proposed in which the logic of framing effects can be developed in order to more fully solve the problem of logical omniscience with its help, and the prospects for such development are discussed.
Derek Turner’s paleoaesthetics in the context of hermeneutics and philosophy of history
Authors:   Novosibirsk National Research State University, Mironov Vasiliy A.
Published: November 2024

The article discusses a new book by Derek Turner, Paleoaesthetics and the Practice of Paleontology, which is the first outline on the given topic with a fairly wide coverage of current research literature. In a sense, Turner’s work can be viewed as an invitation to a dialogue between researchers who are interested in the philosophical and methodological problems of geology in general and paleontology in particular. The presented application of Turner for the construction of the theory of aesthetic values in the earth sciences requires a comprehensive consideration and study by different researchers. The aim of this article is to determine the place of Turner’s concept of paleoaesthetics in the general field of Western European philosophy. The article proves that Turner, like the classic of hermeneutics Gadamer, points to a close relationship between epistemic (historical) and aesthetic values in cognition. The dependence of our aesthetic perception of a fossil on the knowledge of its history, which Turner points out, can be described without distortion of meaning in terms of hermeneutics, namely, through the concept of the hermeneutic circle and the role of prior knowledge in historical knowledge. Also, Turner’s appeal to reflection on metaphors in paleontology, as on the poetic dimension of knowledge, also correlates with the idea of Hayden White, a classic of the philosophy of history of the 20th century, about the need to reflect on the poetic dimension of historical knowledge, as well as the fundamental role of the poetic in the construction of historical works. In addition, in his desire to make paleontology more exploratory and to move away from the descriptive nature of studies of the history of the Earth, Turner conducts the same operation as R. J. Collingwood, who strictly separated the descriptive history of “scissors and glue” from scientific history. In the author’s opinion, Turner’s replacement of the “textual record” metaphor in relation to fossils with the “investigative tool” metaphor is similar in meaning to the replacement of the “source” metaphor by the “evidence” metaphor that Collingwood produced in relation to historical initial data. Based on this, it is concluded that the similarity of the ideas of Turner and the classics of hermeneutics and the philosophy of history gives reason to believe that paleoaesthetics in the form proposed by Turner should be considered as one of the sections of hermeneutics and philosophy of history. Such an understanding of the place of paleoaesthetics in the world philosophical tradition, on the one hand, will contribute to the use of the achievements of the main trends in philosophy for the development of philosophical paleoaesthetics; on the other hand, turning to classical philosophical works will help to avoid doubling the meanings and building similar classical philosophical concepts about geological (paleontological) knowledge.

The Coronavirus Pandemic had multiple implications in different aspects of society. Here we summarize another dimension of consequences, by investigating case reports of Sars-CoV-2 in domestic animals. For this, we performed a systematic literature review and scientometrics analysis. We obtained 428 reports, involving cats, dogs, ferrets, hamsters, and minks, from 34 countries. Cats were the most affected animals. United States presented the highest number of reports. Considering evidence of reverse transmission and the potential risk of virus mutation involving animals, it is important to understand the role of susceptible pets and farm animals in the transmission dynamics.

O estudo teve por objetivo analisar a ocorrência da tuberculose no Rio Grande do Norte (RN), comparando-o com Nordeste e Brasil no período 2014-2022. Realizou-se estudo ecológico de casos de tuberculose notificados no Sistema de Informações de Agravos de Notificação, analisados por localidade geográfica e por grupo social. Utilizou-se dados estatísticos do sistema penitenciário para obter informações sobre pessoas privadas de liberdade (PPL). A incidência de tuberculose aumentou desde o início do período nas três regiões analisadas. Diabéticos e profissionais de saúde apresentaram dados congruentes para as três localidades, enquanto as PPL residentes no RN mostraram grande variação. No RN, alcoolistas, tabagistas e pessoas em situação de rua têm menor propensão a obter a cura da enfermidade e maior probabilidade de ir a óbito em decorrência dela. A alta proporção da enfermidade na PPL do RN pode ser consequência da insuficiência de solários detectada nas unidades prisionais do estado.
Perspectives on theological training in times of crisis
Authors: Nell Ian
Published: November 2024

When crises arise, like in the case of the #FeesMustFall-movement (FMF) during 2015–2017, we often tend to be reactive in our actions and immediate plans are made to address the crisis. In this contribution, however, I want to look at a longer-term solution by making use of Stellenbosch University’s five core values. The values of excellence, respect, responsibility, equity, and compassion will be examined in this contribution to empower lecturers who prepare students for church ministry. The basic research question that will be investigated is: How can the five core values of Stellenbosch University help the lecturers with the preparation of students for ecclesiastical training in times of crisis? In response to this, each of the values will first be explained, after which their meaning and impact on theological training will be examined. Afterwards, some crises in the theological training will be investigated where some of the values conflict with each other. At the end, we will turn to the re-scripting of the narrative of higher education by looking at the extended curriculum program (ECP) at the Faculty of Theology at Stellenbosch University.
FICTION TEXT AS A SHELTER FOR THE TRUE PAST
Authors:   Ivan Franko National University of Lviv, Lviv, Ukraine, Heryliv Nataliia

Background. The article is devoted to the study of the problem of post-totalitarian trauma in modern Ukrainian literature, in particular in novels, which, thanks to their genre features, are able to depict not only phenomena, facts, but also broad contexts. The relevance of the research lies in the analysis of various human behavioral models caused by the activities of the totalitarian system, the so-called big changes that are finally reflected in the literary texts of modern authors as those who are ready to offer for articulation the silenced and hidden. The purpose of the study is to demonstrate the ability of trauma novels to accumulate memory about the true past, despite the influence of totalitarian practices, to show the mechanisms and approaches when encountering a traumatic experience in the novels "Museum of Abandoned Secrets" by Oksana Zabuzhko and "Amadoka" by Sofia Andruhovich. Methods. To achieve the goal, the research used a historical and cultural approach, "memory studies", and a comparative method. Results. A novel text describing traumatic events and their consequences provides the possibility of a conditional encounter with the past. Memory serves as a tool for these meetings as a mediator between what was, is and will be. The work of memory is made much more difficult when the official history is falsified. Under such conditions, individual stories are of great value. Especially those that talk about the experience of living similar events in similar circumstances. A broad background, a large number of individual stories with a common denominator is needed to refute false narratives and promote a true past. Conclusions. It has been found that a literary text (as a tool and artifact) depicting trauma, the truth about it, can perform a therapeutic role, contribute to the strengthening or construction of identity, and counter falsified narratives. On the specific semantic lines of the analyzed texts, it is demonstrated how different persons in the same circumstances behave differently, and the common behavioral traits of the characters-actors who are directly confronted with the trauma of the past are traced.
