In animal characterization research it is essential to establish ranges of typical and fluctuating behaviours of its variables and parameters. For this, the use of robust statistical inferences constitutes a relevant tool. Thus, the study of body traits in a rustic dual-purpose avian population was approached, through correlation and principal component analysis (PCA), contributing to its morphometric characterization and verifying the usefulness of the statistical methods used in a small group. In total, 52 chickens (males and females) were evaluated, classified as adults and older adults, analysing a series of quantitative traits. An association was found between live weight and skull width, middle finger length, wing length (p < 0.01), back length, keel length, breast width, beak length and tarsus length (p<0.05), in adult males, while for older birds calculations are suggested as selection criteria between live weight with keel length and neck length. On the other hand, in adult females, live weight did not show the zootechnical relevance observed in males, while in older females a positive relationship of some body characteristics with live weight was evident. The correlation analysis was useful to provide morphometric links in both sexes and age groups, but not the PCA, which showed good performance in body measurements of males before that of females, in conditions of reduced effective population size (risk) and with native phenotypes.
New records of Scomberoides tala (Cuvier, 1832), Barred Queenfish (Actinopterygii, Carangiformes, Carangidae), from southwestern Taiwan

Published: January 2025

Specimens of Scomberoides tala (Cuvier, 1832) were collected from southwestern Taiwan in the northwestern Pacific Ocean. While this species has been documented in other regions of the northwestern Pacific, our specimens mark its first recorded occurrence in Taiwan, bridging a previously identified distribution gap in this region. Additionally, we suggest that the distribution of this species may be shifting northward, potentially driven by global warming, as the northern records were reported rather recently.
Postacie świętych jezuickich w dominikańskiej parenezie na przykładzie kazań Fabiana Birkowskiego
Authors: Rowińska-Szczepaniak Maria
Published: January 2025

Fabian Birkowski is considered as one of the most outstanding Polish preachers of the post-Tridentine era. Although he was a member of the Dominican Order, he is believed to have been also closely affiliated with the Society of Jesus. This was evidenced in the sermon delivered by the Jesuit Adam Makowski during Birkowski’s funeral. Therefore, this paper is an attempt at interpreting the Dominican preacher’s writings concerning the saints of the Society of Jesus. The article demonstrates the versatility of the themes which Birkowski used when presenting the figures of the Jesuit saints as well as the abundance of means of artistic expression which he employed. These are particularly numerous in his Latin oration on Saint Francis Xavier, which serves as an example of the use of marine metaphors in reference to missionary themes. This is an interesting application of this type of metaphors, as they typically have been used in literature in other contexts.

Evolution of folded biopolymers requires effective and fast search of both the conformational space for folding and the sequence space for evolution. Molecular information theory and energy landscape theory show that the alphabet size of extant proteins and RNA is just enough to fulfill these requirements, given the constraints posed by the chemical physics of these polymers. Empirical estimations of the size of the effective sequence and conformational spaces of natural biopolymers support the theoretical predictions.

Tropinota (Epicometis) hirta (Poda, 1761) (Coleoptera: Cetoniidae), a polyphagous agricultural pest that causes significant economic damage to fruits, vegetables and cereals. Due to its presence during the same period as bees, chemical control methods are not recommended. This study aims to evaluate the effectiveness of plant lectins as bioinsecticides in comparison to synthetic insecticides. Adult insects were collected from various locations in İvrindi district of Balıkesir, Türkiye, between March 25 and June 6, 2024. The insects were fed in vivo with lectins from Wisteria floribunda (Willd.) DC. (Fabales: Fabaceae) (WF), Phaseolus vulgaris L. (Fabales: Fabaceae) (PV), Triticum vulgaris L. (Poales: Poaceae) (TV) and Phytolacca americana L. (Caryophyllales: Phytolaccaceae) (PA) at concentrations of 200, 250 and 300 mg/g for 7 days. The highest lethal effect among the applied lectin doses was detected at the PA300 dose. Upon examining the insect gut tissues, it was found that the TV300 lectin dose contained higher levels of oxidants compared to the synthetic insecticide. Additionally, the applied lectins exhibited inhibitory effects on the activity of various digestive enzyme in insects. Our findings suggest that lectins can be used as a biodegradable alternative to chemical insecticides for controlling T. hirta.
Democratic Consent Under False Pretences

Published: January 2025

Democratically, the permission of any candidate or party to occupy office is based on consent conferred upon them by voters in the previous election. This article examines why and how political misinformation affects that collective electoral consent. Political misinformation can under certain circumstances morally invalidate consent given in an election. That is so when the falsehoods changed the outcome of the election. That is true, regardless of whether the falsehoods were intentional or the result of culpable ignorance.

The problem of connective tissue dysplasia is caused by the widespread spread among the population, the progressive nature of the disease, the involvement of various organs and systems in the lesion, a sufficiently high disability of patients and a decrease in working capacity. The aim – of the study was to study the serum content of certain pro- and anti-inflammatory cytokines in adolescent girls with undifferentiated connective tissue dysplasia and menstrual cycle disorders. 245 adolescent girls aged 11 to 17 years were examined (14.0 ± 0.15 years). Among them, 176 patients assigned to the main group were characterized by menstrual irregularities and the presence of UCTD. The control group was represented by conditionally healthy females of the same age in the number of 69 people. The content of interleukins - IL-1β (1. -4, -6, -10, -17A, and tumor necrosis factor-а were determined in blood serum samples using commercial enzyme immunoassay systems. It was found that in UCTD with menstrual cycle disorders in adolescent girls, the concentration of proinflammatory IL-6 in the blood serum increased (p = 0.002), at the same time, no changes in the content of IL-1β (IL-4, IL-10, IL-17A and tumor necrosis factor-ɑ (p > 0.05) were detected. The obtained data characterize the features of cytokine status, in menstrual disorders against the background of undifferentiated connective tissue dysplasia in adolescent girls and can be used to develop effective individualized schemes of diagnostic and therapeutic, and preventive measures.

Authors: Worku Bethlehem , Shibeshi Nurelegne , Eun Jong-Bang , Yoon Youngmo
Published: January 2025

Research background. Green extraction technologies, such as microwave-assisted extraction, have been used to replace conventional methods of isolating essential oils from plants. In this study, the essential oil was extracted from the Lippia adoensis variety koseret using the advanced method of microwave-assisted hydrodistillation. The main objective was to investigate the effect of irradiation time, microwave power and particle size on the yield and chemical composition of the essential oil extracted from leaves dried in an oven
at 50 °C and room temperature.
Experimental approach. The drying experiments were initially carried out by oven drying and drying at room temperature until 10 % of moisture was achieved. Several essential oils were then extracted from the oven-dried samples for a preliminary study, followed by optimisation of the essential oil yield. The Box-Behnken design with response surface methodology was used to optimise the process and effectively analyse the influence and
interaction of the factors on the essential oil yield. The chemical composition and functional groups of the essential oil from both samples were then analysed.
Results and conclusions. The micrographs of the oven-dried leaves showed damage to the glandular trichomes. The analysis of variance showed significant linear, quadratic and interaction effects of particle size and time, as well as of microwave power and time on essential oil yield. The optimal conditions were: 30 min irradiation time, 550 W microwave power and a particle size of 0.5–0.7 mm, resulting in essential oil yields of (0.49±0.01) % from the oven-dried leaves and (0.40±0.01) % from the room-dried leaves, which accounted for (85.1±0.8) and (87.2±0.7) % of the oils, respectively, with linalool being the predominant component. Fourier-transform infrared spectra showed the presence of hydroxyl functional groups, confirming the chemical composition results.
Novelty and scientific contribution. The results showed the effect of drying methods and microwave-assisted process parameters on the quantity of the produced essential oils. The essential oil yield obtained by the innovative microwave-assisted hydrodistillation results in an efficient process and product quality that can be a very useful ingredient for the food and pharmaceutical industry.

Published: January 2025

The study was intent on assessing the socio-economic impact of a zinc mine in South Africa through the application of people-centric digital tools using a case study research methodology. The global mining industry is undergoing significant technological shifts to modernize, improve operational sustainability, and align with the environmental, social, and governance (ESG) agenda. While the case study mine is a more modernized mine, continuous improvement around the 'social' pillar becomes critical, and to this end application of people-centered digital tools presented as the vehicle to understand community needs and impacts. Despite considerable annual corporate social investment by mines annually, the overall impact or social return on investment is marginally understood. Towards contributing to addressing this gap, digital ESG 'social-related' data gathering tools for mines decision-making were developed, including the training-needs assessment tool, community-social needs assessment, small, micro, and medium enterprise (SMME) communications and engagement tool, digital leadership competencies gap assessment tool, and change management blueprint, which further allowed for customization to the mining context. Hence, the novelty of this paper relates to applying digital tools to provide real-time information of the needs of a community, both socially and economically. The findings suggested that these digital tools enabled gathering of information for the establishment of regional and operational baselines towards enabling of social investment returns in relation to socio-economic transformation development interventions. These tools have been applied to a zinc mine context, with lessons and experiences obtained through this study, invaluable to the application of these digital tool in other mines in South Africa.
The study was conducted in September 2023 across five host communities, surrounding the zinc mine, in the Northern Cape region, with 120 participants involved in the application of three relevant community-related digital tools, which included the training needs, community-social needs, and SMME communications and engagement tools. It was evident that the digital ESG tools could be used for data gathering for the mine's informed decision-making and allowed for securing of insights on community needs in near real-time, and further proved practical for community use.
Ammonium thiosulfate leaching of gold from electronic printed circuit boards - effect of solution copper concentration
Authors: Maharaj D. , Moyo T. , Petersen J.
Published: January 2025

This study investigates the effect of ammonium thiosulfate on the leaching of gold from the contacts of unpopulated cut electronic printed circuit boards (PCBs). Studies in the literature show ammonium thiosulfate to be a viable option in comparison to the commonly used but hazardous cyanide leaching route. However, the simultaneous dissolution of Cu interferes with the Au leaching reaction, often limiting the extraction to moderate levels. To optimize the system, an ammonium-thiosulfate system containing 0.5M ammonia, 0.5M ammonium thiosulfate, and Cu(II) sulfate at varying concentrations was studied as an alternative hydrometallurgical option for the recovery of gold from PCB. Tests were done with unpopulated standardized model PCBs (cut to 15 x 30mm pieces). Gold extraction of 47.3% was achieved after a 24-hour leaching experiment with a 0.02M copper background concentration. Further experiments focused using different initial background Cu concentrations (0M - 0.1M) to determine its effect on both gold and copper extractions. An initial Cu concentration of 0.045M resulted in the highest gold extraction, with 93.7% extraction after 6 hours of leaching. Further analysis of the data shows that the kinetic rate of gold leaching is correlated in a first-order dependence with the actual copper concentration in the solution, which increases with the concomitant dissolution of copper and gold from the PCBs. A lower threshold of 0.017M and an upper threshold of 0.15M copper in solution were determined, in between which gold extraction shows this first-order rate increase. The upper threshold is potentially linked to the onset of copper precipitation, which blinds the metal surfaces, slowing further leaching. The findings of this study suggest that in an industrial recovery operation of gold from waste PCB using the thiosulfate method, copper concentrations need to be carefully monitored, and the process should preferably operate with uncut or coarsely cut untreated boards to minimize exposure to copper circuits.

This article aims to address a theoretical-reflexive work that facilitates understanding the state of the ethical question in socio-educational research from a qualitative perspective. Faced with the predominance of quantitative research in universities at both the international and national level, we are committed to qualitative research from the perspective of Critical Pedagogies. In this way, it is understood that education and research can transform reality and a fundamental aspect of analysis is the ethical question. Firstly, key ideas about research in the socio-educational field from a qualitative perspective at the University will be addressed. Secondly, the historical view of ethics in socio-educational research will be analysed. Thirdly, it will point out key ethical issues in socio-educational research from a qualitative perspective. Fourthly, it will reflect on research competence in education, including both challenges and opportunities that we are currently facing in universities. Challenges such as the collective construction of knowledge; the need to consider the intersectionalities of gender, race, social class, etc.; the care of all the people involved in research processes. In conclusion, the political and ethical relevance of any socio-educational research process is highlighted, underlining the need to continue reflecting on this issue in relation to the construction of a participatory model that focuses on the care of the people involved.

Published: January 2025

Teacher professional development is a key factor in enhancing pedagogical interactions. However, implementing programs that are tailored to teachers' specific needs and teaching contexts remains challenging. This article examines a professional development program in pedagogical mediation based on action research, designed for early childhood educators in Chile. The study employed a case study design, involving nineteen teachers and six trainer educators. Data was collected through semi-structured interviews and written reports, which were analyzed using reflexive thematic analysis. The findings highlight four key aspects for teacher professional development: reflective chaining, video-based training, the role of the critical friend, and work within professional learning communities. These categories form a continuous action-research and reflection spiral that enhances teaching professionalism and self-awareness of practice, promoting a shift from the individual to the collective and from the simple to the complex. This approach fosters a collaborative culture of improvement, strengthening professional development and serving as a model for other programs that contribute to quality in this educational level.

The study/research presents the results of a thesis that is justified by the search for understanding how the subjectivation of the teacher takes place and what processes of cyberformation and modes of subjectivation emerge in contemporary university teaching even in the face of the appeals of cyberculture, contemporary culture mediated by networked technologies and their implications for everyday processes of communication, creation and dissemination of knowledge. The aim of the research is to understand what discursive practices constitute being a teacher and what cyberformation processes result from university teaching that can emancipate subjects in contemporary times. Qualitative, multi-referential and articulated with the methodology of conversation, the research has an archaeogenealogical approach and seeks to create an ontology of the present of being a teacher. The data produced and analyzed in online conversations with twenty-nine teachers working in higher education in licentiate courses on four continents, America, Africa, Europe and Asia, constituted three Categorical Units of Analysis of teachers' discursive practices: virtuality, intersubjectivity and cyberformacivity. Intertwined with the research's theoretical framework, namely Agamben, Ardoino, Arendt, Bruno, Deleuze, Freire, Foucault, Han, Hooks, Lemos, Lévy, Moraes, Morozov, Najmanovich, Nietzsche, Nóvoa, O’Neil, Santaella, Santos Silva, Silva, Vieira Neto e Zuboff, the data revealed clues, pointing to how, in university teaching, being a teacher and the processes of cyberformation can promote principles that foster emancipation and critical technological awareness in subjects.
Liquid level tracking for a coupled tank system using quasi–lpv control
Authors: Teppa-Garran Pedro , Muñoz-de Escalona Diego , Zambrano Javier
Published: January 2025

This article proposes a gain-scheduling procedure based on quasi-LPV modeling for a nonlinear coupled tank system to track the liquid level with zero steady-state error. The nonlinearities are directly represented by a parameter vector that varies within a bounded set constrained by the physical limits of the tank system levels. This approach enables accurate nonlinear system modeling using a linear parameter-varying model. State-feedback linear controllers are designed at the extreme vertices of the bounded set. The global controller is derived as the weighted average of local controller contributions, with the weighting determined by the instantaneous values of the parameter vector. Two interpolation mechanisms are proposed to implement this weighted averaging of the linear controllers. The results confirm the effectiveness of the proposed method in achieving accurate liquid level tracking.

Published: January 2025

This paper presents an architecture based on the MANET (Mobile Ad Hoc Network) paradigm as an emergency communication system between users of electric bicycles. The solution consists of 4 mobile nodes representing the users and a main fixed node, which emulates a bicycle docking station. This architecture allows multi-hop communication between the nodes, using the proactive routing protocols OLSR (Optimized Link State Routing) and BATMAN (Better Approach to Mobile Ad Hoc Networking). The study was divided into 3 main stages. First, an analysis of the wireless medium was performed to determine the maximum transmission distance and the maximum bitrate between 2 nodes. Subsequently, the throughput behavior was characterized in a multihop configuration consisting of 4 nodes in order to establish the network capacity in terms of bandwidth. Finally, a web application was implemented for the transmission of audio and text traffic. Regarding the evaluation of the proposal, two scenarios were designed to emulate the integration of a new cyclist to the network and the communication between two users in motion. The results reveal that OLSR provides a better system operation, with a throughput of 2.54 Mbps at 3 hops and a PRR (Packet Reception Rate) higher than 96%. In addition, it guarantees a delay within the ITU-T (International Telecommunication Union-Telecommunication) G.114 recommendation for bidirectional communication.

Information security threats are one of the most important problems of our time. In general,
a threat is a potential event, action (impact), process or phenomenon that can lead to damage to someone's interests. There are many ways to implement information security threats, but one of the main ones is the exploitation of information security vulnerabilities. According to
a recent report by Positive Technologies [1], in 2023, vulnerability exploitation became one
of the main methods of attack on organizations (32 %). Vulnerabilities are exploited in accordance with a certain attack scenario, which is conventionally divided into the following stages: conducting reconnaissance, conducting an attack, developing an attack on an information system, obtaining benefits. Thus, this work is devoted to the analysis of a number of information security vulnerabilities in 2024, modeling attack scenarios when exploiting these vulnerabilities and establishing of recommendations for eliminating the possibility of exploiting vulnerabilities based on organizational and technical measures.

To assess the diagnostic accuracy of two-dimensional shear wave elastography (2-D SWE) and point shear wave elastography (pSWE) in detecting liver fibrosis stages in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), a comprehensive search was conducted across four databases up to February 9, 2024. A bivariate random-effects model was used to analyze the diagnostic accuracy of the methods. After screening, 13 studies involving pSWE included 1527 patients, while nine studies involving 2-D SWE included 1088 patients. The areas under the summary receiver operating characteristic (SROC) curves for diagnosing significant fibrosis (F ≥ 2), advanced fibrosis (F ≥ 3), and cirrhosis (F = 4) using pSWE and 2-D SWE were as follows: 0.84 (95% CI 0.80–0.87), 0.91 (95% CI 0.88–0.93), and 0.94 (95% CI 0.91–0.95) for pSWE; 0.83 (95% CI 0.79–0.86) 0.85 (95% CI 0.82–0.88), and 0.89 (95% CI 0.86–0.91) for 2-D SWE, respectively.

Repetition Suppression and Related Effects
Authors: Kryukov Vitaliy I.
Published: January 2025

We present an extensive review of the repetition effect aiming to understand a simple experimental fact: why the repetition of a stimulus leads to reduced neural activity as compared to unrepeated stimuli. Previous attempts to understand this fact were connected mainly with the application of the mechanisms of local models (synchrony, facilitation and sharpening). We show that the Neurolocator model earlier proposed for the explanation of neural memory, focused attention, and Pavlovian conditioning can also successfully explain most difficult cases of repetition effects. The Supplement Material includes wide range of related effects such as habituation and sensitization, negative priming, inhibition of return, whole brain segregation and integration. All of them need an additional works to build specific models in each case, but we believe that their successful modeling will be closely connected with the Neurolocator model.
Teaching ukrainian phonetics to high school students in preparation for final assessment
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Shovkovyi Vyacheslav
Published: January 2025

Background. The article discusses the teaching of phonetics in preparatory courses for final exams in Ukraine. Both National Multidisciplinary Testing (NMT) and External Independent Testing (EIT) evaluate students' phonetic competence as a component of their overall competence in the Ukrainian language. Test takers are expected to demonstrate mastery in various topics, including classification of sounds, alternation, assimilation, simplification of sounds, stressing words, means of melodiousness, defining syllables, etc. Teachers who prepare students for their final exams face challenges, such as limited time and gaps in students' background knowledge. Therefore, there is a need to devise effective strategies for test preparation in alliance with programme requirements. The article focuses on developing the study model to enhance phonetic competence through an action-oriented and systematic approach.

Purpose. The study explores the efficacy of the strategy designed to develop phonetic competence in high school students in preparation for the final assessment in Ukraine (NMT/EIT).

Methodology. The study was piloted with 27 students of the preparatory department at Taras Shevchenko National University of Kyiv. The experiment involved comprehensive sampling and further analysis of overall outcomes and individual task results to assess the methodology's effectiveness. The results of the final test were processed by the case method; that is, the test outcomes were analysed in general and for each task in particular.

Results and discussion. The use of various types of phonetical exercises based on action-oriented and systematic approaches led to improving students' recognition, replication, and mastery of phonetic nuances. The research suggests that prioritising inductive reasoning and connecting language study with communicative practice should be core principles, especially in time constraints. Systematisation may be achieved through incorporating a block learning technique along with explanatory and illustrative methods. Further research should focus on developing methods of teaching phonetic assimilation and alternation.
Principles and criteria for developing pre-service teachers' assessment literacy in assessing english language skills
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Lavrenchuk Yuliia
Published: January 2025

Background. Language assessment literacy (LAL) entails various skills, methods, techniques and principles that pre-service teachers are expected to master as part of their university training. In the European context, significant attention has been paid to defining the essence, challenges, and potential reforms concerning LAL. Advancing the practices of teaching assessment to pre-service teachers, and promoting improved methodologies for assessing language skills should also become a priority in Ukrainian scientific settings.

Purpose. The article outlines the principles and criteria for developing teachers' language assessment literacy through the lens of European experience. A review of the relevant literature on the topic empowered the author to determine the theoretical and practical components the university training has to include. The study evaluates the alignment of these competencies with the 30 bachelor study programs in Ukrainian higher institutions to identify gaps and opportunities for improvement.

Methodology. This study is developed within the conceptual framework of competency-based education (CBE). A systemic analysis of literature was employed to identify and examine the key components of teacher language assessment literacy: theoretical knowledge, practical skills, judgements and practical steps taken by teachers during assessment procedures. A comparative analysis was performed based on 30 curricula at 23 Ukrainian universities that train bachelors majoring in secondary education in English.

Results and discussion. The study revealed that among 30 bachelor study programs in Ukrainian educational institutions, the majority (80%) offer theoretical and practical preparation for assessment that is embedded within different pedagogical and methodological courses. 10% provide separate courses in assessment, while 10% do not include assessment in their study programmes.

Based on these findings, it is advised that universities prioritize teaching assessment, as it directly impacts educational planning, implementation and washback. If assessment is not treated as a distinct competency, graduates may develop their own understanding of assessment through observation or practical experience, lacking a robust theoretical foundation.
Dog in Neolithic and Bronze Age Cultures in China
Authors:   Institute of Archaeology and Ethnography, Siberian Branch, Russian Academy of Sciences, Russia, Kudinova M.A.
Published: January 2025

The monograph summarizes all currently available data on the status of the dog in the Neolithic
and Bronze Age cultures of China, its role in the economy and worldview of the ancient population
of this territory. The work introduces numerous and varied sources on archaeology, ethnography,
and folklore of China, which, due to the “language barrier,” were previously not available to Russian
researchers. For the first time, a significant amount of archaeological materials related to dogs
(accompanying burials, images, etc.) has been systematized; epigraphic, ethnographic, folklore data,
and narrative sources have been used for comparative analysis.
The book is addressed to archaeologists, ethnologists, specialists in oriental studies and
everyone who is interested in the culture of East Asia.
Three Global Human Migrations in Eurasia. –Vol. VI, pt. 2: Dispersal of Denisovans and Neanderthals in Southern Siberia
Authors:   Institute of Archaeology and Ethnography, Siberian Branch, Russian Academy of Sciences, Derevianko A.P.
Published: January 2025

The monograph is part of a multi-volume edition, the previous fi ve volumes of which, as well as the fi rst part
of the sixth volume, were published in 2015, 2017, 2018, 2019, 2020, and 2022. The book consists of two sections.
The fi rst section discusses the issues of the formation of the Middle Paleolithic industry and continuity between the
Middle and Upper Paleolithic in the territory of Central Siberia, Tuva, Transbaikalia, and Cisbaikalia. The second
section is dedicated to the settlement in Altai of representatives of the Neanderthal taxon, the fossil remains of which
were found in several caves. The assumption of alternating habitation by Denisovans, Altai Neanderthals, and modern
humans in Denisova Cave is not confi rmed by the materials of archaeological research, indicating that only Denisovans
exclusively inhabited this site. At the fi nal stage of the Middle and Upper Pleistocene in Southern Siberia, the late
Homo erectus, Denisovans, and Chagyrskaya Neanderthals could have dispersed.
The book is addressed to specialists in archaeology and anthropology.

Optimization Problem of Constructing Linear Regressions with a Minimum Value of the Mean Absolute Error on Test Sets
Authors: Bazilevskiy M.P.
Published: January 2025

This article is devoted to the problem of selecting a given number of the most informative regressors in linear regressions. When using the ordinary least squares method, the exact solution to this problem by the criterion of maximizing the coefficient of determination when using the entire data set can be obtained as a result of solving a specially formulated mixed 0-1 integer linear programming problem. However, in machine learning, an important stage in creating a reliable and efficient model is its construction based on the training set and checking the accuracy of its prediction based on the test set. Therefore, in this article formulates an optimization problem for subset selection in linear regressions based on the criterion of minimizing the mean absolute error on the test set. The formulation is based on a well-known technique, according to which absolute errors should be presented as the difference between two non-negative variables. Computational experiments were carried out using the statistical data on athletes' salaries stored into the Gretl package and the LPSolve optimization problem solver. For this purpose, the training set was formed from 70%, 75%, and 80% of observations. In all these cases, the average decrease in the value of the coefficient of determination of the models was 24.76%, 18.4%, and 12.22%, but the mean absolute error decreased by 24.8%, 26.3%, and 21.05%, respectively. Experiments showed that the average time to solve problems when minimizing the mean absolute error on test sets was 2.33–2.85 times higher than the time to solve problems when maximizing the coefficient of determination on training sets.
The Theme of Marriage in F. Scott Fitzgerald's Prose
Authors: Harmon Lucyna
Published: January 2025

Fitzgerald is the author of many short stories and five novels, heavily infused with autobiographical elements. The characters created by the writer often resemble himself or his wife Zelda and the events depicted mirror documented episodes from their lives. In this article, I present the recurring theme of marriage in the writer's works, appearing in various forms in both his short and long prose. I also highlight the vagueness of literary terms such as theme, motif, plot, and character, which often intersect and do not always allow for clear differentiation.
Translating Third Culture Elements in Light of Scenes-and-Frames Semantics
Authors: Gąska Michał
Published: January 2025

The object of the translational considerations made within the framework of this article are the elements of the third culture, which are an indication of literary multilingualism and multiculturalism. In the example of the novel Pachinko by Min Jin Lee and its renderings in German and Polish, the influence of translational interventions on the image of the third culture among the recipients of the translations is demonstrated. The paradigm of anthropocentric translatorics as well as the scenes-and-frames-semantics serve as the theoretical-methodological foundation of the analysis presented here. The aim of this contribution is to illustrate how translators influence the image (the scene) of the elements of the third culture among the recipients of the translations through the use of explicative translation techniques.
Translation and the Community: Case Studies of Contextual Distortion
Authors: Teng Wei , Viselli Antonio
Published: January 2025

This article explores the process of involving cultural and linguistically diverse (CALD) communities in attempts to improve the quality and effectiveness of community translations, with special attention paid to feedback received from CALD lay-readers in attempts to ameliorate translations. Through corpus analysis of healthcare and legal aid documents translated from English to Mandarin, the authors in this study analyse the complexities of reaching pragmatic equivalence in translations based on a set of pre-established criteria. What is at stake in these examples is that they occasionally result in cases of pragmalinguistic failures that can be termed ‘contextual distortions’.
