Impact of the Coronavirus Pandemic and Increased Water Availability of the Lake Baikal on the Development of Tourism in the Republic of Buryatia
Authors: Sanzheev E. D.
Published: February 2025

Aim. Assess the impact of the coronavirus pandemic and the increase in the level of the Lake Baikal as factors influencing the development of tourism in the Republic of Buryatia.Methodology. An analysis of the development of tourism in the Republic of Buryatia was carried out based on statistical data and information from the relevant ministries of the republic, Rosstat and Buryatstat. The work used stock materials on tourism and recreational resources and tourism infrastructure of the Baikal Institute of Nature Management SB RAS. Based on a systematic analysis of statistical data, the results of expeditionary research, the cartographic method and GIS technologies, the negative consequences for the tourism industry of the republic due to an increase in the level regime of the Lake Baikal are presented.Results. The specifics of the impact of the onset of the high-water period and the coronavirus pandemic on tourism at the regional level have been identified. The results of the study show that various natural phenomena, such as a pandemic and an increase in the level of the lake, overlapping each other, can have a significant impact on the operating conditions of the tourism industry. It has been established that as a result of an increase in the level of the Lake Baikal and flooding of recreational areas caused significant damage to the tourist and recreational resources of the coast. This included reductions in area, partial destruction and deterioration in the quality of beaches, negative changes in the aesthetic properties of coastal complexes, destruction of forests used for recreational purposes, and damage to tourism infrastructure. Recommendations were formulated to reduce the negative consequences for the tourism industry due to flooding, in particular on the development of measures to prevent damage to the tourism industry facilities, on taking into account the risks of flooding when making decisions, the need for bank protection work, on amending the regulatory documents, providing assistance entrepreneurs involved in the tourism business.Research implications. Currently, there is a lack of research to assess the impact of changes in the level regime of rivers and reservoirs on the development of the tourism at the regional level. For the example of the Republic of Buryatia, the influence of lake level fluctuations is considered Lake Baikal on the tourist and recreational resources of the coast. The results of the work made it possible to formulate recommendations for preventing the negative impact of flooding on the tourism sector.

Published: February 2025

Aim. To analyze historical background and main events, which determines the way of functioning and evolution of the energy system of Great Britain.

Methodology. The paper covers the problems of energy transition of Great Britain from conventional to renewable energy sources, the main methodology can be defined as standard statistical approach and method of historical research. Mainly, the aim is to undertake step by step analysis of official historical and statistical data. Such official data can be downloaded from government resources, for example, historical data sets for certain period (gov.uk), from resources, providing statistics for pollutants (EPER – The European Pollutant Emission Register), or resources, providing statistics for levels of atmospheric pollution and human wellness (Department for Environment, Food & Rural Affairs).

Procedure and Methods. The time period of the historical development of thermal power industry in the UK – from the mid-19th century to the present was analyzed in details. The main events through industrial evolution, such as new technologies and types of fuel, which determines the way of functioning and evolution of the energy system of Great Britain, were highlighted. As shown in the article, the discovery of the hydrocarbon basins of the North Sea in 60s did not affect the change in fuel consumption in the field of thermal energy. Only the privatization of this sphere forced the owners to switch to cheaper natural gas and easier-to-operate gas power plants, and forces the rise of renewable energy. The main and most important events in the field of environmental legislation of the country, which went parallel with industrial development, and was targeted against climate change, are highlighted. It is shown that the UK can rightfully be a pioneer in the widespread use of the most environmentally friendly sources of electricity. It is shown that the current structure of fuel consumption, as well as the structure of electricity generation by fuel types, differs significantly even from the state of twenty years ago. The article also gives a number of reasons for the crisis situation of 2021. The events of this year have shown that it is not yet possible to completely abandon traditional power plants, even in such a developed and prepared country as the United Kingdom.

Research implications. Not only the development of the energy sector is considered, but also the interrelation of its evolution with the directed work of law-making structures and organizations is traced, the principles of making important decisions for the sector are defined. Also, analysis of these important solutions and energy and fuel consumptions statistics shows, are these solutions reasonable, and if they can be useful and suitable in connection to similar evolution of energy system in Russia.

Published: February 2025

Aim. To determine the possible participation of agricultural production in ensuring the development of tourist destinations in the Bukhara region in order to possibly attract additional tourists and increase the time spent by tourists in the Bukhara region.

Methodology.  Based on systematic observations and statistical information, modern tourist traffic to the Bukhara region has been studied, and the existing main tourism facilities that determine modern tourist traffic with specifics for the Russian user have been evaluated. Based on the calculation of the coefficients of localization of agriculture, possible directions of agrotourism have been identified to increase the traffic of tourists and the number of days of stay. The regional specialization of agriculture was calculated to identify potential destinations in the development of agricultural tourism in the region.

Results. The growth of the participation of the tourism industry in the economy of Uzbekistan has been established against the background of global trends. The patterns of the most important tourist traffic in the Bukhara region (time aspect) are revealed: an increase in the importance of local tourism and an increase in the number of arrivals from Russia. The leading role of the Bukhara region in agricultural production with high growth rates in the last decade is shown based on calculated coefficients of localization of agriculture and per capita production of agricultural products in the regions of Uzbekistan. The specialization of the districts of the Bukhara region in one of the most tourist–attractive areas of agriculture - fruit growing is analyzed in more detail. The most diverse fruit production areas are Zhondorsky, Romitan, Peshkunsky and Shafirkan districts. The main trends in the development of tourism in the districts of the Bukhara region have been identified based on the formation of new directions and routes combining several areas of tourism.

Research implications. A modern assessment of the tourist flows of Uzbekistan (domestic tourism and foreign tourism) is given. The bottlenecks of tourism in the Bukhara region have been identified. New routes have been proposed, including elements of religious, ecological and agricultural tourism.
Readiness of Bachelor of Technical-Vocational Teacher Education Pre-Service Teachers of Camarines Sur Polytechnic Colleges
Authors: Lomeda-Junio Michelle M.
Published: February 2025

This study aimed to investigate the extent of the pre-service teachers in Bachelor of Technical-Vocational Teacher Education Program being ready to align with the Philippine Professional Standards for Teachers. Moreover, it identified potential correlations between pre-service teacher profiles sex, academic track, and area of specialization and subject handled in terms of their PPST readiness scores. It was discovered that there is a promising foundation in terms of literacy, numeracy and communication skills level of pre-service teachers; however, a lot has yet to be achieved overall. There remains a great deal more work to do around curriculum, assessment techniques and engagement of diverse learners. The research went on to identify the establishment of stronger community links and professional development prioritized in the refining of teaching philosophies and collaboration. One of the interesting findings of this research was the strong association of the pre-service teacher profile and PPST readiness. The academic track and area of specialization had a higher relation compared to the subject handled during practice teaching. This would then imply that there could be benefits to be made in designing BTVTEd programs responsive to pre-service teacher backgrounds with unique skill gaps and ensuring that graduates are better prepared for the PPST and subsequent teaching tasks. In that light, the research recommends that BTVTEd programs integrate training that domiciles core academic skills, elements of curriculum development and curriculum assessment practices, and strategies for catering to diverse learners. Besides, community engagement and professional development programs in fine-tuning pre-service teachers will go a long way in contributing to their general preparedness.

Píntalo de negro: los caminos de Orson Welles en el film noir
Authors: Castillo Munailla Andrea , Galindo Aguilar Daniela , Oré Arroyo Carlos , Sánchez Barbarán Mirko , Villafuerte Angola Saulo
Published: February 2025

El film noir marcó una época sumamente importante dentro del cine por la nueva estética visual con la que se narraban las historias, así como por la presencia de una nueva mirada sobre la realidad. Este género cinematográfico recoge una serie de herencias artísticas y las plasma en cintas que confieren al género una característica más heterogénea. Pero las películas clásicas del cine negro se diferencian del estilo de Orson Welles, quien instauró su propia mirada y abrió nuevos caminos cuando se acercó al género.

Published: February 2025

This study aims to describe and illustrate the communication strategy of Corporate Social Responsibility (CSR) implemented by Pabrik Gula Tjoekir towards Islamic boarding schools (Pondok Pesantren) in Cukir Village, Diwek, Jombang, East Java. The research method is a qualitative approach using primary data based on interviews, observations, and documentation, as well as secondary data from various sources such as journals, articles, and related literature. The research subjects consist of the Assistant Secretary General and the Assistant Human Resources of Pabrik Gula Tjoekir as the parties responsible for CSR activities, and the Islamic boarding schools in the surrounding area, namely Pondok Pesantren Tebuireng, Pondok Pesantren Madrasatul Qur’an, Pondok Pesantren Putri Walisongo Cukir, and Pondok Pesantren Darul Falah IV Cukir as the recipients of CSR. The results indicate that the communication strategy involves determining the communication targets, selecting the media, and crafting the message, with the decision-making process involving key stakeholders, namely village heads and boarding school caretakers. The CSR focuses more on social and educational aspects, and there are discrepancies in CSR implementation related to the understanding of the surrounding community about the CSR concept.

The Qur'an that has existed from revelation will always be relevant in every era with its each context. The Qur'an will always be a guidence for every challenge of the changing times. The repetition of the word (tikrār) kulū wasyrabū in the Qur'an has a lot of wisdom and lot of teachings to be learned.  The Interpretation of Tikrār of word kulū wasyrabū raises several concepts and values that could help the understanding of the context of sustainable food needs. This is a qualitative and library research with its primary and secondary data and delivered in a descriptive narration which explains the goals of Sustainable Development Goal 2: No Hunger, and explains the tikrār verses in the Qur'an, explains concepts, values and its implementation in everyday life to provide a great opportunity in realizing the zero hunger goal.
Extruded Epiphysis of the Distal Clavicle Resulting in Painful Nonunion
Authors: Ogawa Kiyohisa , Kawano Yusuke , Tochigi Hirokazu
Published: February 2025

Case:

A 17-year-old adolescent boy sustained right lateral clavicle physeal separation with the epiphysis displaced superiorly in the acromioclavicular joint (ACJ). The ossified epiphysis formed a painful nonunion with the clavicular metaphysis. Resection of the epiphysis has achieved an excellent outcome.

Conclusion:

Children and adolescents with lateral clavicle injuries often develop pseudodislocation of the ACJ in which the metaphysis is displaced due to physeal separation. By contrast, displacement of the unossified epiphysis is extremely difficult to diagnose both radiographically and clinically at the time of injury.

Published: February 2025

Objective. Evaluate how conversations about health warning labels (HWLs) influence attempts to quit smoking (QAs) and sustained attempts to quit (SQAs) among in Mexican adult who smoke. Materials and methods. Data were analyzed from a cohort of 2 164 participants surveyed every four months between November 2018 and March 2021. Multinomial models regressed the frequency of talking about HWLs on sociodemographics and smoking-related variables. Generalized Estimating Equations assessed whether the effect of HWL talking frequency on QAs and, separately, SQAs at follow-up was mediated by the topic of conversation. Results. The majority reported having talked about HWLs (63.7%), regarding the harms of tobacco (73.3%), cessation benefits (58.5%), and lack of credibility/utility of HWLs (9.8%). At follow-up, 42.0% reported an QAs and 20.7% an SQAs. Conversations about HWLs were more frequent among younger participants, those with a university education, those who had recently attempted to quit smoking, and those intending to quit. Talking about HWLs was associated with a higher frequency of QAs and SQAs, mediated equally by discussions about cessation benefits and tobacco harms. Conclusion. Conversation topics around HWL are mesassociated with more smoking cessation attempts. Mexican HWLs focus primarily on harms, more research is needed to evaluate the optimal mix of content.
Conceptualising Fan Persona
Authors: Barbour Kim , Stewart Mark
Published: February 2025

The entanglement of identity and performance within fandoms have been central components of fan studies, whether these fans are focused on sports, music, film, television, literature, celebrity, or something else. Their shared interest and investment in the fan object provide fans with common ground on which to build a collective identity, while the fan object can be a rich source of identity markers, from logos and colour schemes to moral values and philosophical positions. As argued by Busse and Gray in The Handbook of Media Audiences (2011, p. 426), being a member of a fandom facilitates “a particular identity that affects and shapes its members in ways beyond shared media consumption”.In this issue, we invited scholars to bring understandings of identity from fan studies into conversation with ideas of a strategic performance of self, extending existing work on fan personas from both within the Persona Studies journal and beyond. By doing so, we wished to explore how a ‘fan persona’ might be utilised by fans for specific purposes or in different interactions, or to frame individual perspectives, beliefs or interpretations within collective spaces.
A Comparative Study of Ensemble Learning Techniques and Mathematical Models for Rigorous Modeling of Solution Gas/Oil Ratio
Authors: Yavari Hossein , Qajar Jafar
Published: February 2025

The solution gas/oil ratio (Rs) represents the quantity of gas dissolved in oil under reservoir conditions. It is a vital parameter in petroleum engineering, defining the gas content available during production. While many experimental techniques exist for measuring this ratio, they often require considerable time and resources. Thus, mathematical and intelligent models are essential for accurate determination. A total of 720 data points from diverse geographical regions were collected from published studies for this research, using gas-specific gravity, temperature, bubblepoint pressure, and oil API gravity as inputs, with the solution gas/oil ratio as the output. Statistical and physical analyses assessed the impact of parameters on the solution gas/oil ratio, revealing that temperature does not always decrease dissolved gas. Beyond a specific point, known as the inversion temperature, higher temperatures enhance gas solubility. The data set was split, with 80% allocated for training and 20% for testing. The accuracy of the Al-Marhoun model, originally established from 160 data sets from the Middle East, was evaluated using test data, which produced a root mean square error (RMSE) of 468.79 scf/STB. The recalibration of coefficients using 576 training data points and the differential evolution (DE) algorithm led to the formulation of New Model 1. By incorporating the temperature effect and defining the inversion temperature, New Model 2 was developed. Testing results showed that New Model 1 achieved an RMSE of 100.97 scf/STB, while New Model 2 reached 105.1 scf/STB, both showing better accuracy compared with previous mathematical models, including the Al-Marhoun model. Subsequently, machine learning techniques were applied, including the multilayer group method of data handling (GMDH), voting regressor (VR), extra trees (ET), histogram-based gradient boosting regression (HGBR), extreme gradient boosting (XGBoost), and gradient boosting with categorical features support (CatBoost) for the modeling process. Notably, models such as ET, HGBR, XGBoost, and CatBoost effectively captured the temperature effect from the data. The performance of the models was evaluated using statistical and visual analyses. The HGBR model outperformed all others, achieving a training error of 0.0044 scf/STB and an RMSE value of 73.03 scf/STB on the test data, demonstrating its clear superiority among the considered models.
Study of the Heat Extraction Performance of Integrated Enhanced Geothermal Systems Based on a Novel Semi-Analytical Model
Authors: Liang Yanzhong , Teng Bailu , Dai Dan , Shi Jialin
Published: February 2025

An integrated enhanced geothermal system (EGS) includes vertical wells (i.e., injection wells and production wells), horizontal wells, and multiple hydraulic fractures. Due to the limitations in computational efficiency, numerous studies focus on the heat transfer behavior in the fracture section. However, the thermal interactions of the wellbore section have not been hitherto considered, which can result in inaccurate evaluations of heat extraction performance in EGSs. To solve this issue, we propose a novel semi-analytical model, combining numerical solutions for wellbores and fractures with analytical solutions for geothermal formation. Compared with the traditional numerical models, the proposed model achieves a considerable increase in computational efficiency. Subsequently, we conduct a thorough study to investigate the effect of various parameters on the heat extraction performance of the integrated EGSs. The calculation results show that the heat exchange behavior along the wellbore can significantly influence the temperature change in the fractures and the outlet temperature. Especially in the late production period, the wellbore plays a more important role in increasing the fluid temperature compared with the fracture. A lower injection flow rate, as well as a larger geothermal gradient, is more conducive to the heat absorption of the fluid in the wellbore section. Moreover, the anisotropic thermal conductivity presents a more significant impact on the outlet temperature in the early production. With a given extraction area, there is an optimal fracture number (determined as 6 in this study) beyond which the increase in total heat extraction becomes slight.

The intensive and irreplaceable consumption of precious metals (PMs) including Au, Pd, and Pt in the electronic and catalysis industries, coupled with their scarcity in the earth’s crust, demand innovative recycling solutions for PM sustainability1-8. However, efforts to recycle PMs from leachates of their waste are frustrated by an unsatisfactory extraction capacity at low concentrations and remain predominantly focused on gold, leaving other PMs unexplored9-13. We report the ultrahigh reductive recycling of PM ions and their simultaneous aqueous-phase deposition on semimetallic transition metal dichalcogenides (TMD) of TiS2 and TaS2 nanosheets. Notably, TiS2 shows unprecedented high extraction capacities of ~8 g/g, 2.3 g/g, and 1.15 g/g for Au, Pd, and Pt ions, respectively, and the adsorbed PM ions directly transformed into nanoparticles deposited on the nanosheets. Mechanistic studies reveal that water-mediated electron donation from the sulfur site of the semimetallic TiS2 and TaS2 nanosheets is responsible for the ultrahigh extraction capacity, with a single TiS2 molecule donating more than 13 electrons to gold ions. This electron transfer is mediated by the formation of sulfur-oxygen species during water dissociation. We further demonstrate the selective and complete recovery of Au, Pd, and Pt from real-world waste streams including electronic waste, spent catalysts, and automotive catalytic converters.
The Moderating Role of Religiosity in the Relationship between Technology Adoption and Resilience: A Study of Muslim Female Entrepreneurs in the Arab World.
Authors: Jasim Reem
Published: February 2025

Many studies have traditionally portrayed religiosity as a factor that enhances resilience in difficult times. This study delves into a more complex role by investigating how religiosity correlates with the resilience of Muslim female entrepreneurs within an Arab-Muslim context, addressing a gap in the entrepreneurship literature that often overlooks both female entrepreneurs and non-Western contexts. Specifically, the study examines technology adoption as an entrepreneurial resilience strategy during crises. Using a quantitative method with a sample of 307 female entrepreneurs, it analyses the relationship between religiosity, technology adoption, and resilience in the face of adversity.
The results suggest that while religiosity may impose constraints, it moderates the positive relationship between technology adoption and entrepreneurial resilience. At higher levels of religiosity, this relationship is amplified highlighting the importance of aligning business practices with religious values. This paper contributes to the theological turn in entrepreneurship research by integrating religiosity with entrepreneurial resilience strategies, thereby extending resilience theory beyond its traditional boundaries.

In response to the ongoing decline in the productivity of rice varieties cultivated in Togo, the major challenge is to select highly productive varieties adapted to the diverse agroecological conditions of the country. To address this, the present study explored gamma radiation-induced mutagenesis techniques on the IR841 rice variety to create potential genetic diversity, which is essential for varietal improvement and selection. The objective of this work was to determine the existence of morphological variability, indicative of genetic diversity, among the induced mutant lines of the irradiated variety. A total of 50 induced mutant lines of the IR841 rice variety, as well as two controls, the non-irradiated IR841 variety and the NERICA_L14 variety, were evaluated. The experimental design was a completely randomized block design with three replicates. A total of 18 descriptors (5 qualitative and 13 quantitative), were used. The results revealed significant phenotypic variability both within the evaluated mutant lines and between these lines and the controls. Qualitative traits such as panicle exsertion, leaf color, and plant architecture highly significantly varied. Approximately 70% of the mutant lines presented good panicle exsertion. The leaf coloration diversity ranged primarily from intermediate green to deep green. The quantitative traits also varied considerably, including plant height (44 to 106 cm), tiller number (18 to 156), and days to 50% flowering (68 to 115 days). These traits enabled the grouping of the 50 studied mutant lines into 4 clusters. These results demonstrate morphological variability, and thus potential genetic diversity, among the evaluated mutant lines.

Authors: Oni Sarah , Bamisaye Abayomi , Mosaku Abiodun , Ejitola Zainab
Published: February 2025

Starch is a polymeric carbohydrate which is made up of several glucose units connected by glycosidic linkages. It can be sourced from plant tubers and grains. With the increase of new food and non-food industries, more starch is needed as a raw material and there is the need to look for alternative sources of commercial starch. In this study, starch was extracted from water yams (Dioscorea alata), which is considered as lesser yam and thereafter, modified chemically via acetylation, oxidation, and a combination of acetylation and oxidation processes. Using established techniques, the physicochemical characteristics and nutritional makeup of the unmodified and chemically modified water yam starches were assessed, and the outcomes were compared. Assessment using a Fourier Transform Infrared spectrophotometer (FTIR) was carried out to ascertain how the functional properties of both unmodified and modified starch had changed. The moisture content of modified starches was higher, while the ash, fat, and protein contents were lower in comparison with the unmodified. Compared to other starch samples, acetylated/oxidized starch exhibited a higher swelling power, a better ability to absorb water and oil, and a higher content of crude fiber. Compared to unmodified starch, oxidized starch was more soluble. When comparing unmodified starch to modified starch, FTIR analysis showed differences in the absorption bands of the former at 3389 cm− 1 (O-H), 2932 cm− 1 (C-H), and primary, secondary, and tertiary amide moiety at 1079, 1643, and 1205 cm− 1, respectively. The physicochemical and nutritional properties of the starch were generally affected by modification making them a potential excellent material for industrial applications.
Fertigation with Fe-EDTA, Fe-DTPA, and Fe-EDDHA Chelates to Prevent Iron Chlorosis of Sensitive Species in High-pH Soilless Media
Authors: Hershkowitz Julie A. , Dey Mackenzie G. , Heins Royal , Bugbee Bruce
Published: February 2025

Multiple studies have examined the use of chelates to correct pH-induced Fe chlorosis. Here we report the effects of three common chelates on prevention of Fe chlorosis in two sensitive species at high pH. Calibrachoa and soybean were grown in three media pH ranges (6.0 to 6.5, 7.0 to 7.2, and 7.6 to 7.8) and supplied with 1 mg·L−1 Fe as Fe-EDTA, Fe-DTPA, or Fe-EDDHA through fertigation. Chelate effectiveness was quantified by chlorosis rating and dry mass. In Calibrachoa, all three chelates prevented chlorosis at media pH up to 6.5, but above pH 7.2 only Fe-EDDHA was effective. Dry mass decreased as pH increased, but the decrease was less within the Fe-EDDHA treatment. Fe-DTPA was intermediate. There is a wide range in cost: Fe-EDDHA is currently four times, and Fe-DTPA is two times, the cost of Fe-EDTA. Fe-EDDHA binds Fe to pH 9, Fe-DTPA binds to pH 7.5, and Fe-EDTA binds to pH 6.5. Consistent with the stability constants for each chelate, the lower-cost Fe-EDTA chelate was effective in preventing chlorosis in Calibrachoa at media pH below 6.5. We conclude that the additional expense of Fe-DTPA and Fe-EDDHA is only necessary for Calibrachoa when the pH is above 6.5. However, Fe-EDDHA consistently resulted in greater dry mass of soybeans than Fe-EDTA in all pH levels. This suggests that Fe-EDDHA might improve growth of some species, even at a pH below 6.5.
Die Titel und die Einleitungen der Kapitel im 1. Buche von Ps.-Maurikios
Authors:   St. Petersburg State University, Shuvalov Petr V.
Published: February 2025

A comparative analysis of the chapter titles and text of the first book of the late antique military treatise Strategikon allows to put forward the hypothesis that its text was constituted in several stages. Of particular importance here are the wording of the titles and the peculiar beginnings or introductions to most of the chapters, which summarise the content of the preceding sections. A comparison of the passages clearly shows the sequence of formation within each chapter. We should assume at least 5 consecutive phases of text development: author and 4 editors. At first (phase 1a–1b), on the basis of the extant sources, the author of the book created as part of the treatise a text in four sections, organised by the beginnings according to the scheme of genetivus absolutus (primary chapters *1, *2 + 3, *4, *5 + 9). Then another editor (Leg, phase 2) inserted into this codex in the middle of the text *5 + 9 two bifolia with the text of military laws organised by μετὰ-constructions (*6 + 7, *8), resulting in the actual division of the text *5 + 9 into two sections *5 and 9. The next editor (phases 3a–3b) then rewrote the entire text into a new codex, providing it with headings (following the πῶς… scheme), what consolidated the division of the text into seven chapters (1, 2 + 3, 4, 5, 6, 7 + 8, 9), but he could not, however, fully understand the system of incipits of the original text. The new editor (Optim) made a series of additions in the form of glosses and inserted leaves (phase 4). The main development of the text was completed in the next phase (5a–5b–5c), when two new headings (3 and 8), structured in a different scheme (περὶ…), an introduction to chapter 8, and a general table of contents for Book 1 were inserted into this codex. The text was then rewritten into a new, third codex, which fixed the position of interpolations in the text.
From Classics to Digital Philology: On the Origin and Growth of Stylometry
Authors:   St. Petersburg State University, Kovalev Boris V.
Published: February 2025

This article is devoted to the history of stylometry and its development at an early stage. Stylometry is an applied philological discipline that considers style as a set of quantitative parameters. Stylometry arose on the material of classical studies. Using the example of the most reliable and authoritative stylometric method to date — Burrows’ Delta — the advantages and disadvantages of this type of analysis are examined. The genesis of the term “stylometry” is established. In the seminal book of G. Martynenko “Fundamentals of Stylometry” it is indicated that it was coined by the German classical philologist W. Dittenberger. The study reveals that the term “stylometry” actually existed in the 19th century in the meaning of ‘the art of measuring columns’, and it is not used in Dittenberger’s works. This term was introduced by W. Lutoslawski, who tried to solve the problem of periodisation of Plato’s dialogues. It turns that “stylometry” was first used in a new meaning on May 21, 1897, during a report by W. Lutoslawski at the Oxford Philological Society. In Russia, the term first appears in a review in 1898 in the form стилометрия, and in Morozov’s 1915 article in the form стилеметрия, which became widespread in the Soviet academic community.
New insights on measuring soil water content with low-cost sensor
Authors: Lovato Brum Marcelo , Cocco Rodrigues Pablo Eanes , Dalcin Martins Juliano , Swarowsky Alexandre
Published: February 2025

Using sensors to estimate soil water content is important for managing water resources and making decisions on their multiple uses. However, commercial platforms are still extremely expensive, and the development of more accessible systems is essential. This study assesses low-cost capacitive sensors v1.2 to estimate water content in soil using the Arduino platform. Undeformed samples of two different soils (Rhodic Paleudalf and Rhodic Hapludox) were collected at two different depths with three sample volumes. The weight difference data due to sample drainage were collected every 5 min together with the reading values of the soil sensors. To evaluate the obtained results, statistical resources were used, such as Pearson correlation analysis (r), simple linear regression, second-order polynomial regression, root mean square error, Willmott index, and performance index. It was possible to verify that factors such as soil type, sample volume, and the time interval between data collection affect the performance of the sensors. The shortest time intervals between each reading of the sensors showed that soils with sandy texture should be calibrated with second-order equations and with reading intervals not exceeding 24 h.

A abordagem da pesquisa é qualitativa, fundamentada nos princípios de Lüdke e André (1986) e Richardson (1999), e segue o método autobiográfico em educação, com respaldo em Ferrarotti (2010, 2014), Passeggi (2010, 2011), Josso (2009, 2010) e Delory-Momberger (2012). Como instrumento para a construção dos dados, adotamos as entrevistas narrativas guiadas pelas concepções de Jovchelovitch e Bauer (2002). Participaram do estudo quatro docentes que lecionam em turmas multisseriadas do Ensino Fundamental I - anos iniciais (1° ao 5° ano). Como fundamentação teórica, embasamo-nos Hage (2006, 2014), Amiguinho (2008), Souza (2012), dentre outros, que assentam sobre classes multisseriadas, e Molina (2002), Caldart (2001) e Arroyo (1999, 2001), que versam acerca de educação do campo. Quanto aos resultados alcançados, as narrativas permitiram, inicialmente, que os/as professores/as refletissem os caminhos trilhados para se tornar docente, revelando os laços com a comunidade rural, as experiências, as motivações e os sentimentos que os guiaram à profissão, lançando um olhar mais profundo sobre suas próprias histórias. Concernente às práticas de ensino, identificamos que a presença da prática colaborativa permite aos docentes reconhecerem a heterogeneidade dos estudantes de idades e níveis de escolaridade diferentes, possibilitando a aprendizagem de maneira integrada a partir da mutualidade. Outra prática recorrente empregada pelos/as docentes para legitimar as raízes culturais dos sujeitos que vivem no campo, é a prática de ensino contextualizada. Nas narrativas, esses formadores explicitaram as principais estratégias aplicadas na organização multisseriada, dentre eles jogos pedagógicos, projetos didáticos interdisciplinares e livros didáticos, com vistas a integrar o contexto rural com a heterogeneidade presente nos espaços multisseriados. Ainda, teceram desafios, superações e alcances frente à pandemia no formato de ensino remoto emergencial
The Power of Social Media in University Life – a Survey-Based Analysis
Authors: Doskaliuk Bohdana , Bulbuk Oleksandr
Published: February 2025

Background. Social media has become essential for universities, both in recruiting students and enhancing their experience. Platforms like Instagram and Facebook influence student perceptions, foster community, and impact satisfaction, yet the effectiveness of these strategies remains under-explored.
Aim. This study examines the role of social media in shaping students' decisions to apply to Ivano-Frankivsk National Medical University (IFNMU) and their satisfaction with their university experience.
Methods. A survey was conducted with first- and second-year IFNMU students from multiple faculties, using closed- and open-ended questions to gather quantitative and qualitative feedback on academic, social, and infrastructural aspects. Data were analyzed to identify key trends in student perceptions.
Results. The study found that personal networks (64%) and social media (25.3%) are significant sources of information for prospective students, with Instagram as the most influential platform. Positive aspects cited included faculty support (35%) and social engagement (20%), while workload (30%) and infrastructure (15%) were identified as areas for improvement.
Conclusion. Social media is a vital tool for engaging IFNMU students, with Instagram and personal networks playing a prominent role. Addressing concerns around workload and infrastructure, alongside strategic social media content, could enhance student satisfaction and attract prospective applicants. Future research should investigate the impact of specific social media content on recruitment and retention.
Depression Symptoms, Risk Behaviors, Somatization and Social Support Within Two Different Microsystems of Early Adolescents
Authors: Sikora Renata
Published: February 2025

The main aim of the study was to find out if early adolescents who attend two different school microsystems i.e. division of high educational outcomes and division of low educational outcomes differ in terms of depression symptoms, somatization, risk behaviors, school stress and the perception of teachers’ social support which they receive at school. There were 60 adolescents who took part in the study. The set of five tools was applied as follows: Children Depression Inventory CDI-2 (Kovacs 2014), Children Somatization Inventory – short (Walker et al. 2009), Children and Adolescent Social Support Scale – a subscale ‘teachers support’ (Malecki et al. 1999), List of Risk Behaviors in Late Childhood and Early Adolescence (Sikora 2016) and a list of school stressors which was created by participants. The results show the medium level of depression symptoms in a whole group and high level of symptoms in girls who attend low outcomes division. The level of somatization is also the highest among girls of low outcomes division. Risk behaviors are declared more often by students of high outcomes division. Social support was viewed differently in two divisions. The teachers’ help was connected to the well-being of students and provided protection against the mental costs of being at school. Study results call for closer attention to be put on the school context of early adolescents. The intervention and prevention programs should consider some cultural changes in risk behaviors and in symptoms of somatization declared by early adolescents in the study

Published: February 2025

Background

The integration of artificial intelligence (AI) in health care settings demands a nuanced approach that considers both technical performance and sociotechnical factors.

Objective

This study aimed to develop a checklist that addresses the sociotechnical aspects of AI deployment in health care and provides a structured, holistic guide for teams involved in the life cycle of AI systems.

Methods

A literature synthesis identified 20 relevant studies, forming the foundation for the Clinical AI Sociotechnical Framework checklist. A modified Delphi study was then conducted with 35 global health care professionals. Participants assessed the checklist’s relevance across 4 stages: “Planning,” “Design,” “Development,” and “Proposed Implementation.” A consensus threshold of 80% was established for each item. IQRs and Cronbach α were calculated to assess agreement and reliability.

Results

The initial checklist had 45 questions. Following participant feedback, the checklist was refined to 34 items, and a final round saw 100% consensus on all items (mean score >0.8, IQR 0). Based on the outcome of the Delphi study, a final checklist was outlined, with 1 more question added to make 35 questions in total.

Conclusions

The Clinical AI Sociotechnical Framework checklist provides a comprehensive, structured approach to developing and implementing AI in clinical settings, addressing technical and social factors critical for adoption and success. This checklist is a practical tool that aligns AI development with real-world clinical needs, aiming to enhance patient outcomes and integrate smoothly into health care workflows.
Designing a multi-sensor interactive tool for communication with older adults living in nursing homes (Preprint)
Authors: Sjölinder Marie , Hollström Elin , Rönntoft Hanna , Ståhl Olov , Helin Anders , Marklund Victor
Published: February 2025

BACKGROUND

Digital tools could meet needs of older adults, and they have the potential to improve quality of life. Tools supporting reminiscence and communication with older adults with dementia could have an impact on interaction with other people and on relationships. However, these tools often take a specific perspective and do not cover both the past and the present and they also often consist of static information about the person instead of capture that people are constantly changing. The aim with the solution described below was to combine reminiscence with dynamic information about present life, and at the same time create a multisensory engaging activity.

OBJECTIVE

This paper describes the work with the iterative development of a multi-sensor interactive solution that supports reminiscence and communication with older adults. The interactive solution consists of two parts, a mini-game on a tablet for gathering information about preferences and interests, and an interactive hand-held device used to present relevant topics for conversation. Two explorative studies were conducted to get initial feedback on the concept and on the context of usage.

METHODS

The solution was developed based on gathered user needs and iterative feedback during the development. A first version of the prototype was tested as a communication support between older adults and a care staff. The second version of the prototype was tested as a communication support between older adults and relatives or friends. Both studies were qualitative and consisted of interviews after the participants had been able to test the solution.

RESULTS

The participants found that both the mini-game and the interactive device were engaging to use and supported the conversation. Most of the participants felt that it was easy to use the interactive device, and they understood how to interact with it. However, some participants thought that the activity with the interactive device had a slower pace than the mini-game. Other participants thought that the technology set-up with the interactive device was too technical and that the mini-game was more straightforward and easier to use.

CONCLUSIONS

In general. the participants thought that the solution could be useful as a conversational support. Some of the participants commented on the overall aim with the solution and confirmed that the traditional paper-based life story format does not work in practice. Further, they also thought that a solution like this could allow the staff to gain greater knowledge about the individuals that are living in the nursing homes. However, the interactive devices would benefit from being developed further with a larger screen and further multimodal features such as sound, light and texture.

CLINICALTRIAL

The article does not present a RCT study, it is based on qualitative research.
