Characterizing Political Campaigning with Lexical Mutants on Indian Social Media
Authors: Phadke Shruti , Mitra Tanushree
Published: May 2024

Increasingly online platforms are becoming popular arenas of political amplification in India. With known instances of pre-organized coordinated operations, researchers are questioning the legitimacy of political expression and its consequences on the democratic processes in India. In this paper, we study an evolved form of political amplification by first identifying and then characterizing political campaigns with lexical mutations. By lexical mutation, we mean content that is reframed, paraphrased, or altered while preserving the same underlying message. Using multilingual embeddings and network analysis, we detect over 3.8K political campaigns with text mutations spanning multiple languages and social media platforms in India. By further assessing the political leanings of accounts repeatedly involved in such amplification campaigns, we contribute a broader understanding of how political amplification is used across various political parties in India. Moreover, our temporal analysis of the largest amplification campaigns suggests that political campaigning can evolve as temporally ordered arguments and counter-arguments between groups with competing political interests. Overall, our work contributes insights into how lexical mutations can be leveraged to bypass the platform manipulation policies and how such competing campaigning can provide an exaggerated sense of political divide on Indian social media.
Diversity and Inclusion in the Sharing Economy: An Airbnb Case Study
Authors: Quattrone Giovanni , Capra Licia
Published: May 2024

The sharing economy model is a contested concept: on one hand, its proponents have praised it to be enabler of fair marketplaces, with all participants receiving equal opportunities; on the other hand, its detractors have criticised it for actually exacerbating preexisting societal inequalities. In this paper, we propose a scalable quantitative method to measure participants' diversity and inclusion in such marketplaces, with the aim to offer evidence to ground this debate. We apply the method to the case of the Airbnb hospitality service for the city of London, UK. Our findings reveal that diversity is high for gender, but not so for age and ethnicity. As for inclusion, we find strong signals of homophily both in terms of gender, age and ethnicity, thus suggesting that under-represented groups have significantly fewer opportunities to gain from this market model. Interestingly, the sentiment associated to same-group (homophilic) interactions is just as positive as that associated to heterophilic ones, even after controlling for Airbnb property's type, price and location. This suggests that increased diversity and inclusion are desirable not only for moral but also for economic and market reasons.

Published: May 2024

The rapid growth in popularity and hype surrounding digital assets such as art, video, and music in the form of non-fungible tokens (NFTs) has made them a lucrative investment opportunity, with NFT-based sales surpassing $25B in 2021 alone. However, the volatility and general lack of technical understanding of the NFT ecosystem have led to the spread of various scams. The success of an NFT heavily depends on its online virality. As a result, creators use dedicated promotion services to drive engagement to their projects on social media websites, such as Twitter. However, these services are also utilized by scammers to promote fraudulent projects that attempt to steal users' cryptocurrency assets, thus posing a major threat to the ecosystem of NFT sales.
In this paper, we conduct a longitudinal study of 439 promotion services (accounts) on Twitter that have collectively promoted 823 unique NFT projects through giveaway competitions over a period of two months. Our findings reveal that more than 36% of these projects were fraudulent, comprising of phishing, rug pull, and pre-mint scams. We also found that a majority of accounts engaging with these promotions (including those for fraudulent NFT projects) are bots that artificially inflate the popularity of the fraudulent NFT collections by increasing their likes, followers, and retweet counts.
This manipulation results in significant engagement from real users, who then invest in these scams. We also identify several shortcomings in existing anti-scam measures, such as blocklists, browser protection tools, and domain hosting services, in detecting NFT-based scams. We utilize our findings to develop and open-source a machine learning classifier tool that was able to proactively detect 382 new fraudulent NFT projects on Twitter.

Authors: Singh Ashwini Kumar , Ghafouri Vahid , Such Jose , Suarez-Tangil Guillermo
Published: May 2024

Cross-platform communities are social media communities that have a presence on multiple online platforms. One active community on both Reddit and Discord is dankmemes. Our study aims to examine differences in harmful language usage across different platforms in a community. We scrape 15 communities that are active on both Reddit and Discord. We then identify and compare differences in type and level of toxicity, in the topics of the harmful discourse, in the temporal evolution of toxicity and its attribution to users, and in the moderation strategies communities across platforms.

Our results show that most communities exhibit differences in toxicity depending on the platform. We see that toxicity is rooted in the different subcultures as well as in the way in which the platforms operate and their administrators moderate content. However, we note that in general terms Discord is significantly more toxic than Reddit. We offer a detailed analysis of the topics and types of communities in which this happens and why, which will help moderators and policymakers shape their strategies to mitigate the harm on the Web. In particular, we propose practical and effective strategies that Discord can implement to improve its platform moderation.
Influencer Marketing Augmented Personalized Assortment Planning: A Two-Stage Optimization Problem
Authors: Yuan Jing , Mensah-Boateng Twumasi , Tang Shaojie
Published: May 2024

Assortment optimization presents a significant challenge for online retail platforms. Its primary objective is to create an optimal selection of products from a vast array of substitutes, which will be displayed to customers with the aim of maximizing expected revenue. The purchase behavior of customers is typically influenced by a choice model that determines the probability of purchasing each product from a given assortment. This paper extends traditional assortment optimization by introducing the integration of influencer marketing, a practice that involves enlisting influencers to promote products and enhance their appeal to customers. While conventional assortment optimization assumes fixed product attractiveness, our model enables platforms to strategically enhance the attractiveness of selected products through influencer marketing, thereby increasing revenue potential. Consequently, we present a novel problem formulation encompassing assortment and influencer marketing planning. Leveraging recent advancements in submodular optimization, we develop effective and efficient solutions for this joint optimization problem.

Authors: Piot Paloma , Martín-Rodilla Patricia , Parapar Javier
Published: May 2024

Hate speech represents a pervasive and detrimental form of online discourse, often manifested through an array of slurs, from hateful tweets to defamatory posts. As such speech proliferates, it connects people globally and poses significant social, psychological, and occasionally physical threats to targeted individuals and communities. Current computational linguistic approaches for tackling this phenomenon rely on labelled social media datasets for training. For unifying efforts, our study advances in the critical need for a comprehensive meta-collection, advocating for an extensive dataset to help counteract this problem effectively. We scrutinized over 60 datasets, selectively integrating those pertinent into MetaHate. This paper offers a detailed examination of existing collections, highlighting their strengths and limitations. Our findings contribute to a deeper understanding of the existing datasets, paving the way for training more robust and adaptable models. These enhanced models are essential for effectively combating the dynamic and complex nature of hate speech in the digital realm.

Published: May 2024

This paper examines the influence of scientific appearance (SA) on post dissemination and analyses a dataset of important actors in Germany, specifically those involved in the dissemination of disinformation on the social media platform Telegram. SA is identified through textual elements such as predefined keywords or digital object identifiers (DOIs). Characteristics and behaviours of actors with and without SA are compared using metadata such as forward counts and original posts. The additional content analysis provides insights into SA's usage and impact. The findings indicate that SA may influence the dissemination of posts and demonstrate how different methods can be applied for studying social media platforms.

Published: May 2024

The RUNX2 transcription factor was discovered as an essential transcriptional regulator for commitment to osteoblast lineage cells and bone formation. Expression of RUNX2 in other tissues, such as breast, prostate, and lung, has been linked to oncogenesis, cancer progression, and metastasis. In this study, we sought to determine the extent of RUNX2 involvement in other tumors using a pan-cancer analysis strategy. We correlated RUNX2 expression and clinical-pathological parameters in human cancers by interrogating publicly available multiparameter clinical data. Our analysis demonstrated that altered RUNX2 expression or function is associated with several cancer types from different tissues. We identified three tumor types associated with increased RUNX2 expression and four other tumor types associated with decreased RUNX2 expression. Our pan-cancer analysis for RUNX2 revealed numerous other discoveries for RUNX2 regulation of different cancers identified in each of the pan-cancer databases. Both up and down regulation of RUNX2 was observed during progression of specific types of cancers in promoting the distinct types of
cancers.

Published: May 2024

Engineered cementitious composites (ECCs) represent a significant advancement in concrete technology, addressing the issues and limitations of conventional concrete and environmental challenges related to sedimentation in rivers such as the Yellow River in China. This study investigates the integration of Yellow River sand (YRS) into ECC mix designs for sustainable development. YRS replacement rates (0, 25, 50, 75 and 100%) with quartz sand are systematically analysed through flexural, compressive, uniaxial tensile and four-point bending tests. In addition, scanning electron microscopy and mercury intrusion porosimetry tests are conducted to investigate the micro-mechanical properties. The results reveal that the optimal mechanical performance with 100% YRS substitution improves the compressive and flexural strengths to 26.4 and 11.5 MPa, respectively. These values are 6.20% lower than the those of the 0% substitution rate. Notably, a 100% replacement maintains an ultimate tensile strain of 3.71%, improving the crack width and spacing compared with those at 0%. The average crack width and spacing decrease by 4.87 and 11.2%, respectively, compared with those of 0% substitution. The four-point bending test results show the highest ductility at a 75% substitution rate. Furthermore, a finite-element method model of ECC beams with YRS is developed and validated under the same loading conditions as the experimental data. This study recommends an analytical method for predicting flexural strength compared with the experimental data, enhancing its suitability for sustainable engineering applications.
Examining the adaptive elastic anisotropy of granular materials
Authors: Singh Shubjot , Buscarnera Giuseppe
Published: May 2024

Changes of granular material anisotropy with stress are a function of numerous microscale attributes, such as contact network, particle size uniformity and shape. Such influences are often represented with fabric variables. Although multiple choices for fabric exist, the question of which variable best explains why and how granular materials adapt to stress is still open. In this study, the effectiveness of different fabric variables in tracking stress-induced anisotropy is compared. The analysis is restricted to a simple, yet fundamental, range of behavioir: elastic deformation. Both particle-scale simulations and continuum analyses are deployed. Analyses based on the discrete-element method (DEM) reveal that, depending on the contact behaviour, anisotropy may emerge even if the topology of the grain contact network is unchanged. The inspection of these results through a continuum-scale hyperelastic constitutive law further reveals that the computed trends cannot be captured without an evolving fabric variable. A comparison between such fabric and multiple microstructural indicators extracted from DEM simulations suggests that elastic stress-induced anisotropy is primarily a manifestation of changes in the anisotropic particle contact area distribution in response to the current magnitude and orientation of force chains. These results not only offer opportunities to enhance current continuum elastic models for granular materials, but can also be used to design testing strategies quantifying changes in fabric anisotropy through multi-scale measurements.

Published: May 2024

Industrial slags produced by high-carbon ferrochrome are a material of complex composition consisting of an oxide part (Cr2O3 , CaO, MgO, FeO, SiO2 , Al2O3 ) and “entangled” metal prills (Crmet ). In order to increase the degree of chromium utilization and reduce losses in the form of metal prills, we conducted the laboratory experiments to study changes in properties of the slag produced by high-carbon ferrochrome through the use of effective and affordable fluxing materials: expanded clay, calcium borate and refined ferrochrome slag. The effect of fluxing additives in the form of expanded clay, calcium borate and slag from the production of low-carbon ferrochrome on the properties of high-carbon ferrochrome slag was studied. Addition of up to 8 % of expanded clay and low-carbon ferrochrome slag leads to a stable decrease in the softening temperatures of the final slags. The greatest intensity of decrease in the softening temperature is observed when calcium borate is injected in an amount of 6 ‒ 10 %. The greatest effect on reducing softening temperatures is exerted by the addition of 10 % calcium borate when introducing high-carbon ferrochrome into the slag, while the temperature of softening beginning decreases by 262 °С, and the temperature of softening end – by 135 °С. All the studied fluxing additives have a positive effect on reduction degree of the residual concentration of metallic chromium in the slag. The most intense decrease in the content of Crmet in the slag is observed with the introduction of 2 % of fluxing materials. The best values for the residual content of 0.7 ‒ 0.8 % Crmet were achieved using 4 % of low-carbon ferrochrome slag and calcium borate. When using expanded clay, an additive in the amount of 10 % is required to achieve such indicators of Crmet . In general, the effectiveness of using the studied fluxing materials to increase the degree of chromium extraction in the production of high-carbon ferrochrome is shown, its content in the slag is reduced by 84 %.

Published: May 2024

When choosing compositions of high-entropy alloys, one of the parameters taken into account is thermal stability. The paper considers the structural transformations of the deformed Al0.3CoCrFeNi high-entropy alloy occurring during its annealing. The material was obtained by argon-arc melting with a mixture of pure single-element components. In order to homogenize the structure, the resulting ingot was subjected to thermomecha­nical processing according to a scheme combining cold rolling with a compression ratio of 50 % and low-temperature annealing (400 °C for 100 h). In the future, the homogenized billet was rolled in a cold state with a compression ratio of 80 %. The structure of the materials was studied directly during heating (in-situ mode) using the method of synchrotron X-ray diffraction. The heating rate of the samples was 20 °C/min, the maximum heating temperature was 1000 °C. The parameters of the alloy dislocation structure (density of screw dislocations, spatial distribution of dislocations) during heating were determined using the modified Williamson–Hall and Warren–Averbach methods. According to the data obtained, the temperature of beginning of formation of a high-entropy phase with a primitive cubic lattice is 560 °C. In the process of heating the material up to this temperature, an increase in density of screw dislocations and formation of a disordered dislocation structure are observed. The nature of change in dislocation density correlates well with the increase in the alloy microhardness. At an initial value of 406 ± 13 HV0.1 (for the deformed material), the microhardness during heat treatment increases up to 587 ± 10 HV0.1 .

Published: May 2024

The authors studied the crystallization process of the Fe – W system, which is the basis of heat-resistant high-speed steel used in plasma arc surfacing on the surface of rolls and various cutting tools. The structure of this material consists of two components: cellular and dendritic. Histogram of the structural elements distribution shows the presence of a single maximum. The most probable size takes a value in the range of 10 – 15 μm. The paper considers the morphological instability of crystallization front (the Mullins-Sekerka instability). The model includes the equations of convective thermal conductivity and diffusion. The Stefan conditions for temperature were set at interface of the phases. Linear analysis of this instability is carried out for two cases: when the convective term in the equations of thermal conductivity and diffusion can be neglected; when convection prevails over diffusion processes. In all cases, it was assumed that the value (1 – ks ) was close to zero, which corresponds to a concentration of the alloying element approximately equal to or exceeding the eutectic one, and a short-wave approximation was also used. In the first case, the analytical view of dependence of the wavelength, which accounts for the maximum rate of interface disturbances growth, coincides with generally accepted concepts. In the second case, the value of this wavelength is directly proportional to square root of the interphase boundary velocity. The limits of applicability of these approximations for various mechanisms of crystal growth were determined. In the case of normal growth, both approximations provide an adequate explanation for the formation of structural elements up to 5 μm in size at a crystallization front velocity of about 2 m/s. For the case of growth due to screw dislocations, the wavelength value corresponding to the fastest-growing perturbation mode in the first case coincides with experimental data at a crystallization front velocity of the order of 10–7 m/s, whereas in the convective approximation such a coincidence is observed at 10–4 m/s. Further development of the model consists in simultaneous consideration of the convective and diffusion components. The results obtained will serve as a material for the research of the Mullins–Sekerka instability for two interface boundaries.

Published: May 2024

The article presents the analysis of the contemporary theoretical and empirical research devoted to evaluation of the effectiveness of mergers and acquisitions by means of short-term event analysis method, managers’ motivation in making decisions on the acquisition of other companies from the perspective of the timing of the expected effect; it adduces and systematizes the limitations of the cumulative abnormal returns (or CARs) method. The authors carry out scientific synthesis of the limitations of the method of capabilities of accurate prediction of the final results of transactions. In particular, the following problems of the CARs method have been identified: determining the date of the event, determining the event window, inconsistencies in research results, outflow of funds from purchasing companies during mergers and acquisitions, arbitrage trading strategies, the lack of long-term predictive value of the method of accumulated excessive profitability, efficient market hypotheses, overcharging of the purchasing company shares.

The authors have made a conclusion about possible inaccuracy of the method if used to evaluate the effectiveness of mergers and acquisitions.

Authors: Nam Woo Joo , Ha Ju Young
Published: May 2024

Purpose: This study aimed to identify the impact of health literacy on adherence of medication among older adults living alone and to determine the mediating effect of e-health literacy in the relationship between the two variables. Method: A total of 91 older people living alone who visited a general hospital and welfare center participated, and data collection was conducted from July 20, 2023 to August 30, 2023. Descriptive statistics, t-test, ANOVA, Pearson’s correlations, Model 4 of PROCESS macro were used for data analysis. Results: Health literacy of older adults living alone was found to have a significant effect on adherence of medication (β=.33, p<.001) and e-health literacy (β=.34, p<.001). E-health literacy was found not to mediate the relationship between health literacy and adherence of medication (Indirect effect: β=-.02, 95% confidence interval [-.08~.02]). Health literacy was significantly different depending on age (F=6.87, p=.002), education background (F=10.36, p<.001), and monthly income (F=7.98, p<.001). There was a significant difference in adherence of medication based on age (F=4.38, p=.015). Also, e-health literacy had significant differences in age (F=10.05, p<.001), education background (F=7.91, p<.001), and monthly income (F=7.38, p<.001). Conclusion: When providing education to older adults living alone to improve adherence of medication, medical staff and nurses should identify health literacy, provide repetitive medication education tailored to the level of health literacy of each elderly living alone, and critically receive indiscriminate health information from the Internet.

Published: May 2024

The aim of this study is to investigate the factors that influence the perceived value and the factors influencing the satisfaction and perceived value derived from the tourism motivations of visitors to the Taehwagang National Garden. Specifically, the driving factors, incentive factors, and perceived value of tourism motivation were set as prerequisites for tourism satisfaction. Recently, Ulsan Metropolitan City has implemented various strategies to develop the Taehwagang National Garden and boost visitor numbers, aiming to transition from an industrial to a tourist city. However, the visitor turnout has been less than expected, given the efforts. In response to the need for strategies to ensure the sustainability of the Taehwagang National Garden, this study was conducted focusing on the characteristics of visitors who have experienced the garden. The results of the study were found to have a positive and significant effect on perceived value among the driving factors, and among the attractive factors, core tourism resources had a positive and significant effect on perceived value, and the convenience of information and facilities had a negative and significant effect on perceived value. Furthermore, a conclusion was drawn that perceived value had a positive and significant effect on tourism satisfaction. Therefore, these findings suggest that it can be used as data for establishing marketing strategies for the Taehwagang National Garden, and it is suggested that visitor satisfaction and operational sustainability can be enhanced by developing content that meets visitor needs and by expanding facilities for relaxation.

Las palabras importan. Apuntes sobre la conceptualización de las violencias que sufren las mujeres por el hecho de serlo
Authors:   Universidad Politécnica Salesiana (Ecuador), Gil Gesto Isabel
Published: May 2024

Asistimos a un momento histórico en el que se alzan voces negando las violencias que sufren las mujeres por el hecho de serlo, amplificadas desde las redes sociales y los medios de comunicación. Negar las violencias que sufren las mujeres es violencia. Frente a la negación, la banalización y la normalización, se impone la necesidad de ampliar, re-conceptualizar, y profundizar en el concepto de la violencia contra las mujeres. El lenguaje no es neutro. Conceptualizar adecuadamente es clave. Existen diferentes perspectivas y definiciones a la hora de hablar de las violencias específicas que sufren las mujeres, y es importante conocerlas porque, de ello, derivan diferentes maneras de intervenir frente a este problema de salud pública global. Los diferentes marcos interpretativos de las violencias que viven las mujeres influyen en el accionar para revertir tal situación (Otero, 2009). Buscar soluciones a esta lacra mundial, definida como “un grave problema de derechos humanos y salud pública que afecta a todos los sectores de la sociedad” por la Organización Mundial de la Salud (OMS, 2003), implica reconocer el problema, pero, para ello, hay que identificarlo con claridad, definirlo y visibilizarlo. Ello no es sencillo puesto que este tipo específico de violencia “ha sido y continúa siendo una cuestión no exenta de controversia en cuanto a su definición” (Cabrera de la Cal y Correa Chica, 2019, p. 11).

Published: May 2024

The present study aims to determine the mediating effect that authentic coach leadership has on the interaction between coach competence and athletes' perceived support for basic psychological needs (BPN). A cross-sectional study was conducted with 115 team sports players (17.96 ±2.85 years of age; 8.18 ±4.67 years of experience) using the Basic Psychological Needs Support, Perceived Authentic Leadership, and Athletes' Perceptions of Coach Competence questionnaires. Correlation and mediation analyses (Coach Competence → Authentic Leadership → BPN Support) were performed. The results show a positive and significant indirect effect (ƥ = 0.288; 95% CI = 0.167, 0.415) of authentic leadership on the direct interaction between coach competence and BPN support (ƥ = 0.277; p < 0.01), increasing the total model effect (ƥ = 0.555; p < 0.01) to aid athletes' perceived BPN support when their coaches are competent and authentic leaders. In conclusion, it is not enough to be a well-prepared coach, he/she must also have the ability to lead, motivate and make decisions taking care of his/her interrelationships with athletes and promoting the satisfaction of basic psychological needs.
Exploring External Load Metrics in Team Handball: A Study of Europe’s Under-20 Male Championship
Authors: Freitas João , Estriga Luisa
Published: May 2024

The objective assessment of external physical loads has become promising in better understanding players’ match loads and responses. However, there is a lack of consensus on the metrics used along with limited information on this topic in elite handball. This study investigated differences in conventional and novel external load metrics according to playing positions. Methods: 27 matches of EHF Euro M20 2022 were used, with a total of 711 player match observations recorded. The data series were collected using a local positioning system (LPS) integrated with inertial measurement unit (IMU) devices. Kinematic variables: match-jerk, match-Dynamic Stress Load (match-DSL), distance covered, distance covered at high speed (HSR distance). Despite the lack of handball-specific validation, differences between studied positions were found in all variables. Greater sensibility seems possible based on the match-DSL compared to match-jerk. Accordingly, Backs exhibited the highest match-DSL values. Divergently, the Wings covered more distance at total and high-speed running while showing lower match-DSL relative to the Backs. The Line Players had similar HSR distances to Backs while covering lower total distances. Future studies are needed to explore the validity of the available metrics and arbitrary parameters, as well as comparing those variables with internal-load variables.

The Zebra finch is a well-studied model animal to study neural mechanisms of speech, and electrophysiology is the primary technique for understanding the song system in them. Most of the studies on zebra finches have focused on intracerebral recordings. However, these methods are only affordable for limited laboratories. Recently, different open-source hardware for acquiring EEG signals has been developed. It's unclear if these solutions are suitable for zebra finch studies as they have not been evaluated so far. Electrocorticography signals can provide a preliminary guide for more in-depth inquiries and also aid in understanding the global behavior of the bird’s brain, as opposed to the more common localized approach. We provide a detailed protocol for acquiring iEEG data from zebra finches with an open-source device. We implemented stainless steel electrodes on the brain's surface and recordedthe brain signals from two recording sites. To validate our method, we ran two different experiments. In the first experiment, we recorded neural activity under various concentrations of isoflurane and extracted the suppression duration to measure anesthesia depth. In the second experiment, we head-fixed the birdsand presented them with different auditory stimuli to evaluate event-related potential (ERP). Results showed a significant increase in the suppression duration by increasing the anesthesia depth and evident ERP response to auditory stimuli. These findings indicate that by our methodology, we can successfully collect iEEG signals from awake and anesthetized birds. These findings pave the way for future studies to use iEEG to investigate bird cognition.
THE POETICS OF O. SHYNKARENKO’S FACEBOOK NOVEL “KAHARLYK” AS A PHENOMENON OF THE UKRAINIAN LITERATURE IN THE DIGITAL AGE
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, ZOZULIA Dmytro
Published: May 2024

The article examines Oleh Shynkarenko’s novel “Kaharlyk” as an example of the Ukrainian literature of the digital age. It is an experimental novel as it combines two forms a digital and printed ones. The purpose of the study is to outline specific features of the poetics of O. Shynkarenko’s Facebook novel “Kaharlyk” as a piece of writing incorporating the characteristics of both postmodernist and digimodernist texts. This predetermines the following tasks: to generalize the characteristic features of digital textuality proposed by A. Kirby, to outline the concept of network literature, to determine the genre features of the novel, to study the characteristic features of its form in Facebook social network (in particular, to analyze author's and reader's comments under the posts-episodes of the novel) and in the printed edition (based on the 2015 book published by Luta Sprava Publishing), to determine, on the example of this novel, how the interaction in the author-text-reader paradigm has changed in the literature of the digital age. The study uses intermedial, intertextual, comparative, and structuralist methods of analysis. The novelty of the article lies in a detailed study of the electronic version of the novel, particularly, in the analysis of author’s and reader’s comments on the Facebook page of the novel “Kaharlyk”. The research showed that typical postmodern features of both the electronic and printed versions of O. Shynkarenko’s novel “Kaharlyk” are as follows: genre hybridity, intertextuality, absurdity, and irony. In addition, the novel possesses the features of a digimodernist text, including onwardness, haphazardness, evanescence, reformulation and intermediation of textual roles, anonymous, multiple and social authorship, the fluid-bounded text, and the nature of electronic-digitality. These features are mostly inherent in the online version of the novel, but are also found in the printed edition.
THE TRANSLATION MISSION OF MYKOLA LUKASH IN THE DEVELOPMENT OF THE UKRAINIAN LANGUAGE CULTURE
Authors:   Petro Mohyla Black Sea National University, Mykolayiv, Ukraine, KUZENKO Halyna
Published: May 2024

The relevance of the article is determined by the general focus of translation studies on the research of the heritage, as well as the practice of artistic translation of the Ukrainian theoretician Mykola Lukash. In fact, in translation studies, the author's method of translation of baroque literature in the polysystem of the Ukrainian literature still remains vaguely defined. The analysis of the influence of the translated baroque literature on the creative and life paths of the artisttranslator seems to be promising. The purpose of the study is to reveal Mykola Lukash’s translation mission as a significant figure in the history of the Ukrainian translation and development of Ukrainian language culture. Comprehensive understanding of the history of the Ukrainian literature, as well as its culture and people is not possible without an overall study of the history of the Ukrainian artistic translation, as well as the Ukrainian translation studies in general. The defender of the Ukrainian culture and, in particular, the language, the ascetic translator Mykola Oleksiyovych Lukash, takes a prominent position in the research. Acting as a mediator, the translator M. Lukash explains the incomprehensible, reveals the author to a new community. He often changes the established view of the work as an obvious and complete thing, convinces everyone with a fresh and deeper interpretation, cancels errors of perception. His characteristic was a bold approach to solving difficult translation tasks, he often experimented with linguistic means. The creative legacy of the master of the Ukrainian translation, M. Lukash, has always aroused the increased interest of specialists in his author's innovations, dominant features of the individual style and method of translation of a certain literary direction and genre. Actually, the translation of baroque literature, the specificity of which is the contrast between reality and illusions, heterogeneous combination of the tragic and the comic, the sublime and the vulgar, the terrible and the funny, i.e. the combination of the book and the folk, the sacred and the profane, brought M. Lukash to a completely new level as after the release of these translations, a language revolution took place in the field of professional translation.
Geometry, kinematics and dynamics of the Mecanum wheel. Unstable motion of the Mecanum vehicle
Authors: Dyakov Alexey S. , Fedorov Dmitry S.
Published: May 2024

BACKGROUND: The Mecanum wheels enable the vehicle to move in any desired direction and increase its mobility when moving along a flat surface. When designing a vehicle, the design loads determine the required driving moments and, as a result, the characteristics of the drivetrain. Thus, determining the loads acting on the Mecanum wheels in stationery and transition events is the most relevant task related to the Mecanum wheel.
AIM: Determination of the traction characteristics of the Mecanum wheel drives, ensuring the given mobility of the vehicle.
METHODS: Simulation of motion of a vehicle with the Mecanum wheels is carried out in the multibody dynamics’ software package. The contact interaction of the Mecanum wheel and rollers with the surface is described on the basis of the rolling theory.
RESULTS: A simple descriptive method for building a roller profile is proposed. The velocities of the vehicle, wheels and rollers for various directions and modes of motion, are calculated. The driving torque required for motion at these velocities is presented.
CONCLUSION: The Mecanum vehicle model makes it possible to determine the kinematic and dynamic characteristics of motion along a flat support in any mode of motion.
Study of the potential use of hydrodiodes to enhance the volumetric efficiency of a centrifugal pump
Authors: Fomenko Vladislav D. , Petrov Alexey I. , Efremov Egor V.
Published: May 2024

BACKGROUND: For centrifugal pumps, especially those with low specific speed coefficients, the volumetric efficiency is a very important parameter that largely determines the overall efficiency of the pump. Meanwhile, the amount of leakage in the flow part of the pump depends on the shape and size of the slot seals on the impeller. In this paper, the attempt to apply the well-known operational principle of a hydrodiode is made in order to reduce volumetric losses in the pump through a reduction in the flow rate coefficient of the slot seal, whose surface is profiled according to the principles of a hydrodiode.
AIM: Analysis of the possibility of utilizing the hydrodiode-like grooves on the surface of a slot seal in order to reduce the flow rate of liquid through the seal based on the computational fluid dynamics methods.
METHODS: The computational fluid dynamics method based on the solving of discrete analogs of the basic hydrodynamic equations is used in this paper.
RESULTS: The parameters of liquid flow in the slot seals with smooth surfaces, concentric grooves, and proposed profiled hydrodiodes in various sizes and shapes have been calculated. The flow rate coefficients for each type of seal have been determined, and comparative graphs have been built.
CONCLUSION: Based on the findings of this study, it can be stated that, overall, the use of hydrodiodes does not give significant advantages over the concentric groove with significantly increased complexity in manufacturing.
