Published: December 2024

Metal(IV) tetraaryl, M(aryl)4, complexes hold great promise as functional building blocks for complex organometallic materials, yet their widespread utility depends on the development of improved synthetic protocols and a deeper understanding of their chemical structure-property relationship(s). Here we show that Os(aryl)4 complexes with pre-installed functional groups (-F, -Cl, -Br, -I, and -SMe) can be prepared from reactions between (Oct4N)2[OsBr6] and Grignard reagents formed by halogen/magnesium insertion or exchange. This approach provides access to compounds that may otherwise prove challenging to prepare through post-functionalization strategies, such as those comprising halogens in the 2- or 5-positions. Furthermore, we show that these tetrahedral complexes can be stabilized by ortho-chloride substituents, moving beyond the alkyl groups that have previously been exploited for this purpose. We characterize these, as well as previously reported, materials using single-crystal X-ray diffraction, solution voltammetry, and UV-vis spectroscopy. We find these compounds, while typically appearing as black or darkly colored in the solid state, yield differently colored CH2Cl2 solutions due to small changes in the λmax and variations in the relative intensity of their four primary absorbance features. Through a comparison of 13 differently substituted complexes, we identify correlations between their electrochemical and optical gaps, and between the E1/2 of their 0/1+ redox event and an adjusted Hammett parameter that accounts for all aryl ligand substituents. This work provides a foundation for advancing new preparative methods to further derivatize such species, and a robust experimental dataset to help benchmark future experimental and computational compound characterization.

Published: December 2024

An approach for obtaining high-level ab initio potential surfaces is described. The approach takes advantage of machine learning strategies in a two-step process. In the first, the molecular-orbital based machine learning (MOB-ML) model uses Gaussian process regression to learn the correlation energy at the CCSD(T) level using the molecular orbitals obtained from Hartree-Fock calculations. In this work, the MOB-ML approach is expanded to use orbitals obtained using a smaller basis set, aug-cc-pVDZ, as features for learning the correlation energies at the complete basis set (CBS) limit. This approach is combined with the development of a neural-network potential, where the sampled geometries and energies that provide the training data for the potential are obtained using a diffusion Monte Carlo (DMC) calculation, which was run using the MOB-ML model. Protocols are developed to make full use of the structures that are obtained from the DMC calculation in the training process. These approaches are used to develop potentials for OH-(H2O) and H3O+(H2O), which are used for subsequent DMC calculations. The results of these calculations are compared to those performed using previously reported potentials. Overall, the results of the two sets of DMC calculations are in good agreement for these very floppy molecules. Potentials are also developed for OH-(H2O)2 and OH-(H2O)3, for which there are not available potential surfaces. The results of DMC calculations for these ions are compared to those for the correspondingOH-(H2O)2 and OH-(H2O)3 ions. It is found that the level of delocalization of the shared proton is similar for a hydroxide or hydronium ion bound to the same number of water molecules. This finding is consistent with the experimental observation that these sets of ions have similar spectra.

Published: December 2024

Transition-metal-catalyzed cleavage of the Si–H bond in silanes to yield silyl radicals requires substantial amounts of energy, which is commonly supplied by photons. For Rh(II) porphyrins, efficient hydrosilylation catalysis only becomes accessible upon site isolation in a MOF, and the formation of free silyl radicals likewise requires irradiation. Within the MOF, however, an uncommonly facile direct silyl radical transfer to olefin substrates is also possible, which makes thermal olefin hydrosilylation accessible at room temperature. The ability of MOF-supported Rh(II) metalloradicals to furnish an unprecedented 3-center-3-electron (3c-3e) Rh(II)-silane σ-adduct enables the assembly of a tri-component transition state that is comprised of Rh(II), silane and ethylene. The tri-component transition state bypasses the high-energy silyl radical species and enables silyl radical transfer with an activation free energy ~15 kcal∙mol–1 below the minimum energy barrier for silyl radical formation. We report direct observation of the 3c-3e silane σ-adduct, which is a stable species in the absence of light and olefins. Furthermore, a combination of experiments and quantum mechanical calculations show that direct silyl radical transfer to ethylene is promoted by the temporary oxidation of the transition structure by a proximal Rh(II) center. Thus, the crucial role of the MOF matrix is to fix the inter-Rh separation in our catalyst at a value large enough for 3c-3e silane adduct formation, but short enough for facile electron transfer.
Chemo-optogenetic dimerization dissects complex biological processes
Authors: Wu Donglian , Sun Xiaofeng , Chen Xi
Published: December 2024

Light offers superior control in terms of high temporal precision, high spatial precision, and non-invasiveness for the regulation of cellular functions. In recent years, chemical biologists have adopted chemo-optogenetic dimerization approaches, such as photo-triggered chemical inducers of dimerization (pCIDs), as a general tool for spatiotemporal regulation of cellular functions. Traditional chemo-optogenetic dimerization triggers either a single ON or a single OFF of cellular activity. However, more sophisticated approaches have been introduced in recent years. These include the ability to turn ON and OFF using different wavelengths of light, tools enabling multi-layer control of cellular activities, and nanobody-tethered photodimerizers. These advancements not only shed light on the study of ubiquitously existing multi-functional proteins but also create new opportunities for investigating complex cellular activity networks.
Expanding the Toolbox for Supramolecular Chemistry: Probing Host-Guest Interactions with in situ FTIR Spectroscopy for Struc-tural and Dynamic Insights
Authors: Moaven Shiva , Vander Griend Douglas , Johnson Darren , Pluth Michael
Published: December 2024

Association constant (Ka) measurements provide fundamental information on host-guest interactions in supramolecular chemistry and other areas of science. Many techniques can be used to measure Ka values, with NMR spectroscopy often providing useful information on time-averaged interactions or changes in geometry due to perturbations in chemical shifts. Here we report the use of in situ FTIR spectroscopy to measure the Ka values of supramolecular host-guest complexes across three classes of host-guest complexes using different types of interactions including hydrogen bonding and halogen bonding. This approach can be performed with minimal sample preparation, does not require deuterated solvents, can measure asso-ciation based on changes in host or guest vibrations, and benefits from a much shorter timescale than NMR spectroscopy. Due to its fast timescale, FTIR spectroscopy also provides details on host/guest conformational changes, such as the presence of unsymmetrical host conformation that are not in the ideal binding conformation until treatment with a suitable guest, which would otherwise not be observed in more common time-averaged NMR measurements. Using this approach, we demonstrated the capabilities and challenges of this technique to investigate host-guest interactions of three anion receptors that use hydrogen or halogen bonding with both mono- and polyatomic anions. In addition to directly observing how host-guest interactions impact bonding within the individual molecules, we also demonstrate that global fitting of the FTIR spectra is an effective and robust approach to measure Ka values of these host-guest complexes. We anticipate that this method will provide a new and useful approach to investigating the dynamics and specific interactions across abroad areas of science.

Published: December 2024

Big data and artificial intelligence (AI) have emerged as a transformative force in materials science. However, the field still faces significant challenges, primarily the scarcity of comprehensive material datasets and the inefficiencies in utilizing existing data to its full potential. In this work, we propose the CrossMat platform, integrating material databases to accelerate material discovery across diverse applications. Currently encompassing fields such as electrocatalysis, thermocatalysis, photocatalysis, solid-state electrolyte materials, hydrogen storage materials, lithium battery electrolytes, thermoelectric materials, and superconducting materials, CrossMat is driven by large language models and machine learning algorithms to significantly broaden the scope of material prediction. By systematically identifying synthesizable, cost-effective, and environmentally stable materials, CrossMat facilitates their adaptation to previously unexplored domains. This approach not only addresses critical limitations in current methodologies but also opens up innovative avenues for the discovery and development of advanced materials.

Published: December 2024

The establishment of bioelectrochemical systems is an appealing strategy to further the development of eco-friendly and efficient bioengineering technologies. However, the major biocomponents used as catalysts have been limited to purified enzymes and live microorganisms. Here, we examined the electrocatalytic activity of membrane vesicles (MVs) produced by Shewanella oneidensis MR-1. We demonstrate that the MR-1 MVs exhibit electrocatalysis coupled with formate oxidation over 16 days and a more stable catalytic current compared with live cells. A colorimetric assay and electrochemical analysis revealed that different MV biogenesis routes critically affect the electrocatalytic activity of MVs. Electrochemical analysis of MVs from gene-deletion mutants revealed electron transfer mechanisms between MVs and electrodes in pathways both dependent and independent of c-type cytochromes in MVs. This research highlights MVs as promising platforms for the design of robust and controllable bioelectrocatalysts, paving the way for future research in biosensing, energy conversion, and biochemical production.

Authors: Davtyan Robert , Piotrowicz Wojciech , Kovács Gyöngyi
Published: December 2024

This study explores the differential skill requirements within supply chain management (SCM) across commercial and humanitarian contexts and career levels. Analysing 116 responses regarding context and 96 concerning career levels, the research confirms the applicability of the T-shaped model, highlighting the distinct skills critical for each sector. Significant discrepancies were found: humanitarian SCM prioritizes functional logistics, while business SCM places a larger emphasis on information technology, customs, transportation, and port/airport management. These findings suggest a dynamic skillset evolution, where functional skills, essentialat entry-level positions, give way to general management capabilities as one progresses. This shift is more pronounced by experience rather than job title in the humanitarian sector. The implications for educational institutions and SCM practice are profound, necessitating curriculum updates to meet changing industry demands and support logistics practitioners transitioning between sectors.

A EUGENIA NO DISCURSO DIDÁTICO E SEUS IMPACTOS NO ENSINO DE CIÊNCIAS
Authors: Monteiro Flávia Leite , Silva Antônio Fernando Gouvêa da , Franco Fernando de Faria
Published: December 2024

Com o desenvolvimento da ciência moderna, começou-se a busca de argumentos científicos que pudessem justificar a marginalização de determinados grupos na sociedade. Nesse contexto, surgem movimentos como a eugenia, cujo pensamento prega que o ser humano pode ser melhorado através de determinadas práticas, como a seleção artificial. Apesar de ter sido muito forte durante as primeiras décadas do século XX, ainda observamos reproduções do discurso eugenista na atualidade. Este trabalho busca compreender em que medida a abordagem crítica de discussões eugênicas nas aulas de   ciências e biologia pode contribuir para a superação das tentativas de naturalizar preconceitos socioculturais. Realizamos uma pesquisa de caráter qualitativo, por meio da análise documental focada no discurso sobre uma visão sociocultural da genética e evolução de autores reconhecidos. Usamos, como fonte de dados, frases emitidas por esses autores em entrevistas, livros e artigos científicos. Posteriormente, essas frases foram classificadas em quatro categorias: determinismo genético, determinismo geográfico, higienismo e racismo científico. Os limites explicativos dessas frases foram trabalhados ao longo deste estudo, utilizando-se conceitos de genética e de evolução para contrapor as ideias eugenistas contidas nelas, trazendo o contexto cultural em que a frase foi emitida. Foi discutido o papel da educação crítica na área de   ciências, bem como sua importância na quebra do ideal de ciência neutra positivista. Concluímos que trabalhar temáticas de eugenia em sala de aula é uma das formas de contextualizar o ensino e auxiliar na superação de preconceitos, de forma a transformar a realidade do educando, passo fundamental para o exercício de uma educação crítica.

Published: December 2024

A humanidade compartilha a era do Antropoceno. Isto é, a ação antrópica modificou irreversivelmente a era geológica do planeta. Desde a Revolução Industrial, os níveis de dióxido de carbono (CO2) elevaram consideravelmente, paralelo a desmatamentos, poluição, expansão urbana e consumismo infinito em um planeta com recursos finitos, ocasionando enchentes, aquecimento global, dentre outras consequências. Desse modo, o uso de energia sustentável é uma opção para mitigar a situação, embora apenas desacelere uma catástrofe iminente. No entanto, nas últimas décadas ocorreu a evolução da reação de fusão nuclear, prometendo quantidades exorbitantes de energia sem emissão de CO2, como alternativa aos combustíveis fósseis e seus derivados menos agressivos. A utilização do isótopo Hélio-3 na reação de fusão está impulsionando países em uma nova corrida espacial, já que esse isótopo é abundante na Lua. Partindo dessa premissa, este artigo discute uma possibilidade de aplicação de sequência didática para alunos do 1° ano do ensino médio, na qual os assuntos básicos que envolvem essa temática são abordados e criteriosamente elaborados, baseando-se em artigos recentes em consonância com conceitos de Ciência, Tecnologia e Sociedade, além de envolver questões sociocientíficas. O despertar crítico dos educandos acerca dessa temática percorre o letramento científico, objetivando, ao final do processo, gerar conhecimento significativo. Afinal, é necessária uma mudança não apenas de matriz energética, mas de um modo de produção mais sustentável e consciente na era do Antropoceno.

Published: December 2024

Neste trabalho, buscamos identificar aspectos da linguagem que se mostram nas produções de Martin Eger, responsável por articular a Hermenêutica Filosófica à Educação em Ciências. Em uma escrita ensaística, destacamos a partir do autor a interpretação como parte do processo de superar a distância que há entre o aluno e a ciência que estuda, considerando esta um elemento humano também presente nas Ciências Naturais. Iniciamos por apresentar como a tradição histórica da Hermenêutica se torna uma Hermenêutica Filosófica por intermédio de Hans-Georg Gadamer. Sob influência deste, Martin Eger foi um dos primeiros autores em língua inglesa a sugerir uma aproximação da Hermenêutica Filosófica à Educação em Ciências Naturais. Mostramos como a linguagem na Hermenêutica Filosófica influenciou as produções de Martin Eger, o que o levou a questionar a dupla hermenêutica apenas às Ciências Humanas e propor uma tripla hermenêutica nas Ciências Naturais. Desse movimento emergem analogias como a cascata de interpretações orientadas pelo diálogo hermenêutico nas Ciências Naturais e no educar sobre/a partir delas. O ensaio evidencia que a interpretação e a linguagem desempenham papéis cruciais na Educação em Ciências, promovendo um diálogo hermenêutico entre alunos e ciência.

EXPLORING SPATIAL AND TEMPORAL VARIATIONS OF AGRICULTURAL DROUGHT IN RORAYA WATERSHED USING NORMALIZED DIFFERENCE DROUGHT INDEX (NDDI)
Authors: Pramestika Mutiara Indah
Published: December 2024

Agricultural drought is a critical concern for food security, particularly in regions with significant climatic variability such as the Roraya Watershed in Southeast Sulawesi. This watershed is vulnerable due to its reliance on rain-fed agriculture and distinctive karst topography. This research aims to describe and map drought-prone areas within the Roraya Watershed using the Normalized Difference Drought Index (NDDI) from 2019 to 2023 comprehensively. The findings indicate a consistent presence of severe drought conditions across the watershed, which led to prolonged dry spells and decreased rainfall. Our results reveal that the Roraya Watershed's agricultural areas are predominantly experiencing severe drought, with NDDI values ranging from 0.25 to 1. Despite some annual variations, the overall trend shows an increasing severity of drought conditions. This research highlights the necessity for targeted interventions and supports the development of effective drought mitigation strategies to enhance the resilience of agricultural systems in drought-prone regions.

Examining the relationship between addiction and jealousy in romantic relationships: An evaluation in terms of behavioral jealousy
Authors: Kolburan Şahide Güliz , Faraji Haydeh
Published: December 2024

Addiction in romantic relationships, which is a chronic problem that harms oneself, one’s partner, and the relationship, refers to the partner’s desire for excessive closeness determined by the intense need for the other. It is known that such dependent relationships are related to jealousy, as there are factors such as lack of selfconfidence, low self-esteem and internal insecurity. The aim of this study is to examine the cognitive, emotional and behavioral dimensions of addiction and jealousy in relationships. It was aimed to evaluate the behavioral dimension of jealousy in terms of partner violence. The study was started after receiving ethics committee approval numbered 2024/03 dated 07.03.2024 from Istanbul Aydın University Social and Humanities Ethics Commission. It was conducted with 334 female and 183 male volunteer participants reached by convenience sampling. The measurement tools used in the study are the Sociodemographic Data Form, the Addiction in Romantic Relationships Scale and the Multidimensional Jealousy Scale. Pearson Correlation analysis, Multiple Linear Regression Analysis and Independent Groups T Test were performed using SPSS 27.0.1.0 Edition (31-Dec-2037). In line with the study findings, it was determined that addiction in romantic relationships was associated with all dimensions of jealousy, but with behavioral jealousy at the highest level. The results of the study reveal that perceptions of inadequacy of personal resources, such as insufficient education and economic level, can increase the feeling of jealousy. However, it appears that increased addiction indicators such as obsession and dedication towards the partner are determined by the behavioral aspect of jealousy. Therefore, the study results indicate that in order to protect both partners in a romantic relationship, it may be useful to focus on what they do with this feeling rather than their feelings of jealousy. Based on this, it can be stated that strengthening individual resources should be preferred to direct interventions against the feeling of jealousy.

Published: December 2024

Today's technological developments make children vulnerable to the threats of the virtual world. In recent years, it is noteworthy that there have been reports in the media that violent digital games have led children to crime. For this reason, the study aims to examine the cases that have occurred in the last year by addressing the issue of digital games dragging children to crime and suicide. In the study, first of all, keywords were determined by literature review. Accordingly, the word groups "digital game", "computer game", "game addiction" and "juvenile pushed to crime " were determined. With the determined keywords, "Google News" was filtered through the search engine between 01.05.2023 – 01.05.2024 and the news was scanned. A total of 368 news reports were examined and 3 cases were identified. The first case was when a 12-year-old boy committed the crime of intentional knife killing of another 13-year-old boy as a result of a task given from a computer game. The second case involved a 12-year-old boy committing suicide with a firearm on the grounds that he was not allowed by his family to play a violent video game called ‘PUBG’. The third case is a 14-year-old boy who committed suicide with a firearm after playing a game called ‘Blue Whale’. The analysis of the cases were transferred to a table. According to the data of the TURKSTAT in 2021, 54.3% of children in the 6-15 age group who stated that they play digital games regularly stated that they play war games. In the literature, there are almost no legal studies on digital games leading children to suicide and crime. Although there is no official data, findings from literature and news reports suggest that possible associations between violent digital games and children's violent behavior towards themselves and their peers should be investigated.
Autism Spectrum Disorder (ASD) or early electronic screen exposure – 67 month-old case study
Authors: Aslan Mahi
Published: December 2024

Concerns about screen addiction have become increasingly prevalent, particularly with regard to its potential impact on children's development. This study examines the possible connection between Autism Spectrum Disorder (ASD) symptoms and early exposure to electronic screens. It focuses on a case involving a 67-month-old child who was heavily exposed to screens during the COVID-19 lockdown. The child spent an average of 5 hours per day in front of screens, which included television and mobile devices. Observations indicated delays in language development, poor social skills, and an anxious emotional state. The family initially associated these symptoms with ASD and sought professional consultation. However, it was observed that the child exhibited behaviors such as restlessness, avoidance of social interaction, and a preference for screen time over fulfilling basic needs, such as eating. These behaviors were particularly evident when the child was not engaged with digital devices, manifesting in sadness, frustration, and anger.
The case highlights how early and excessive screen exposure can lead to developmental and psychological challenges that mimic ASD-like behaviors. Excessive screen time in children has been associated with attention disorders, sleep disturbances, language delays, and emotional instability. In this case, the family did not impose restrictions on screen usage during the lockdown period, which contributed to the child’s increased demand for digital media. The therapeutic intervention focused on reducing screen time and encouraging non-digital activities, including outdoor play and social interactions with peers. As a result, improvements were noted in the child’s anxiety, social engagement, and language development.
In conclusion, this case underscores the importance of distinguishing between ASD and the effects of excessive screen exposure, as the symptoms of both conditions can overlap. Reducing screen time and promoting parent-child interactions are essential in mitigating these developmental issues.
The impact of sexual abuse on addiction: A case study on food addiction
Authors: Cansız Alim , Koçhan Malik Emir
Published: December 2024

Addiction, which is one of the major problems of society and is spreading severely day by day, is considered a complex process where an individual develops an uncontrollable desire for a substance or behavior, continues this desire, and has difficulty ending it despite both physical and psychological harm. Food addiction is a type of addiction where individuals consume food not only to meet their physiological needs but also uncontrollably for emotional and psychological satisfaction. Individuals with food addiction tend to eat to cope with emotional states such as stress, anxiety, and depression, leading to unhealthy eating habits and weight problems. In such addictions, the treatment process requires addressing not only the improvement of physical symptoms but also the emotional and psychological factors that trigger the addiction.
Although food addiction usually arises from depression or other psychological disorders, in some cases, individuals may feel the need to eat to feel better after experiencing abuse. This situation can become uncontrollable, leading to food addiction, which negatively affects both the mental and physical health of individuals.
This study is a case study of a 41-year-old woman named S.A., who developed food addiction as a result of sexual abuse by her parent at the age of 13. The gradual progression of the abuse and the subsequent development of food addiction are examined in detail, along with the effects of EMDR and CBT (Cognitive Behavioral Therapy) on overcoming the food addiction.

Authors: Mares Laura
Published: December 2024

La inteligencia artificial (IA) está configurando un escenario educativo que recuerda a los primeros pasos del uso de la tecnología digital en el aula. En ese entonces, las prácticas educativas y las representaciones mentales sobre la tecnología digital estuvieron marcadas por tensiones y paradojas derivadas de su implementación, el contexto social y educativo, así como otras problemáticas concurrentes del sistema educativo; el analfabetismo, la falta de comprensión de textos o el abandono escolar.
Manipulative technologies in a large amount of linguistic data: Social media
Authors: Pilgun M. A. , Erofeeva I. V.
Published: December 2024

The article presents the results of our study on manipulative techniques based on a large amount of linguistic data from social media and focused on the implementation of a major urban development project in the field of road transport construction in Moscow. The research was conducted using data from social networks, video hosting platforms, microblogs, blogs, forums and review websites (3,358,590 tokens, the audience of 17,688,221). Created during the study, the database contains user-generated content and their digital footprints reflecting user reactions. The data analysis was conducted from a cognitive perspective, employing a neural network text analysis, content analysis, sentiment analysis, digital aggression analysis and lexical association analysis. The Brand Analytics monitoring system was used for data collection, while GPT-4o, GPT-4o mini, GPT-4, TextAnalyst 2.32 and AutoMap were used for the data analysis and interpretation, with the Tableau platform used for visual analytics. The analysis of the data revealed mythological manipulation, speech and psychotechnologies. When manipulative techniques are employed in the media space, rhetorical tropes and figures, sophisms and eristic tricks are actively used. The adaptation of these techniques to the specifics of digital communication allows for indirect influence on the audience, significantly increasing the effectiveness of the impact, which can, in turn, lead to heightened conflict potential and social tension.
Index retardation as the basis of an epic play (a case study of A. Ostrovsky’s dramaturgy)
Authors: Lebedeva A. I.
Published: December 2024

Retardation plays a significant role in A. Ostrovsky’s artistic universe, being prevalent in his works and indicating the intermedial nature of the author’s oeuvre. The strengthening of intertextual connections between literature, theatre, painting and music has contributed to the evolution of traditional genres. In terms of genre, Ostrovsky highlighted the importance of capturing static space, referring to his comedies as paintings, scenes and so on. Small dramatic forms are characterized by a substantial conflict, owing to the fact that the playwright’s focus is not on the development of intrigue but rather on the characters. We discuss the fusion of arts, bringing the static quality inherent in literary paintings and scenes closer to the genre painting. Retardation as the emphasis on the lack of significant movement in a play allows the audience to enter the portrayed space from a distant perspective. The purpose of this article is to examine the artistic time and space in Ostrovsky’s paintings and scenes. The study has found that Ostrovsky frequently employs index retardation within the narrative of his characters. Event-based retardation, which builds tension prior to the climax, differs from index-based retardation. In Ostrovsky’s dramaturgy, index-based retardation serves as a means of emphasizing relaxation, introducing characters into the realm of everyday concerns. The playwright slows down the action in the play by incorporating extraneous elements into the plot, such as repetitions, parallels, quotations and reminiscences. Additionally, he employs plot devices such as metaphors representing unreal spaces (both conscious and unconscious dreams), as well as visual cues such as mirrors, maps, imagery of water and so forth. Focusing on the states rather than actions, as the primary category of fine arts, enables us to imbue the intratextual space in Ostrovsky’s dramaturgy with pictorial art characteristics.
Representation of a fictional (artistic) world by a creative subject
Authors: Kartashova E. P. , Mikheev A. A.
Published: December 2024

The article is an overview of the current and controversial topic concerning the consideration of the author as a creative person who creates a fictional artistic world. The article is theoretical in nature, as it is directly devoted to describing the concept of text analysis with a focus of research attention on the study of a linguistic personality. The purpose of the work is to determine an approach to analyzing the processes of creating works of art and modeling fictional artistic worlds.

The work rethinks and complements the concept of describing a linguistic personality proposed by Yu. Karaulov. The novelty of the work is determined by the shift in focus from attempts to interpret and describe the result of linguocreative activity to the study of the processes that determine it. The change in the subject in the paradigm of linguistic personality research allows us to expand the boundaries of the theory’s applicability, to formulate a more effective methodology in the interdisciplinary space, adapted to modern research into human consciousness.

Further development of this approach to the text analysis and accumulation of empirical data in the future will allow formulating an adaptation theory of text, which is currently being developed by the research team. The results of this work have interdisciplinary potential for use not only in linguistics, general text theory, pragmatics, psycholinguistics, but also in the subject area of cognitive sciences.
Responsibility of Primary School Students as a Social and Personal Virtue
Authors: Matsibora N.
Published: December 2024

The article highlights different views on the problem of responsibility of primary school students as a social and personal virtue. It is established that responsibility is the most important internal regulator of activity, which is manifested in the conscious readiness of a person to follow the norms and rules accepted in society, to evaluate their actions in terms of their consequences for others. The sources of responsibility as a personal phenomenon of a person are considered.

It is determined that the school is the most important significant social institution that directly and directly carries out the education of children and the pedagogical management of family upbringing. The importance of partnership between teachers and parents in implementing a common strategy for the development of responsibility is emphasized. The unity of the educational activities of school, family and community is created by the purposeful systematic work of the school that meets the modern requirements for general secondary education institutions. It is stated that the acquiring responsibility skills in primary school students involves the development of students' ideas (knowledge) about values, moral feelings, motives for responsible behaviour, and gaining experience in responsible behaviour and actions. Parents and teachers play a leading role in fostering responsibility in primary school students. Only the joint purposeful efforts of teachers and parents can influence the development of a child's personality.
