Demonstrating the learning and impact of embedding participant involvement in a pandemic research study: The experience of the SARS-CoV-2 Immunity & Reinfection Evaluation (SIREN) study UK, 2020-2023
Authors: Howells Anna , Aquino Erika Neves , Bose Deepika , Kelly Martin Gerard , Molony-Oates Barbara , Syed Asmah Hassan , Tolley Kim , Neill Claire , Hopkins Susan , Hall Victoria , Islam Jasmin
Published: May 2023

Background
Participant involvement in research studies is not a new concept, yet barriers to implementation remain and application varies. This is particularly true for pandemic response research studies, where timeframes are condensed, pressure is high and the value and inclusion of participant involvement can be overlooked. The SIREN PIP provides a case study for participant involvement in pandemic research.
Methods
SIREN and the British Society for Immunology (BSI) recruited and ran two phases of the PIP, involving 15 members in total over a 16-month period. Activity figures including recruitment interest and PIP meeting attendance were recorded. Feedback from researchers running and presenting at the PIP has been used to evidence its impact on the study. Feedback from PIP members following meetings and through evaluation at the end of Phase 1 was also collected. Feedback from Phase 1 informed our approach to Phase 2.
Results
There was a fifteen-fold increase in applications for joining Phase 2 of the PIP compared to Phase 1. The average meeting attendance rate increased from 76% in Phase 1 to 85% in Phase 2. The SIREN PIP was found to positively impact the design, implementation and evaluation phases of the study and sub-studies. Feedback from PIP members themselves was positive, with members highlighting that they found the role rewarding and felt valued.
Learnings from the PIP have been condensed into five key themes for applying to future pandemic response research studies: the importance of dedicated resources to support participant involvement; recruiting the right panel; understanding motivations for participant involvement; providing flexible options for involvement and the challenge of prioritising participant involvement in a pandemic response study.
Conclusions
This paper has contributed to the evidence base demonstrating that participant involvement can be included in, and adds value to, a pandemic response research study. The SIREN PIP has demonstrated the valuable role participant involvement can play in providing an active feedback mechanism for research. Positive impacts on study researchers and PIP members themselves have been demonstrated. Future pandemic studies should invest in participant involvement, and this could be enabled through the introduction of a national PIP forum.

Published: May 2023

Background
Inpatients with high risk of venous thromboembolism (VTE) usually face serious threats to their health and economic conditions. Many studies using machine learning (ML) models to predict VTE risk neglected the influence of ‘fuzzy population’, and achieved inferior results. The ‘fuzzy population’ phenomenon is common in clinic and it means that normal individuals can share the same or very similar characteristics with the patients and they are hard for doctors to differentiate, due to the low incidence rate and complex pathogenesis of diseases. Considering the effect of ‘fuzzy population’, our study aims to develop a new VTE risk assessment model suitable for Chinese medical inpatients.
Methods
Inpatients in the medical department of Peking Union Medical College Hospital (PUMCH) from January 2014 to June 2016 were collected. A new ML VTE risk assessment model was built through population splitting. First patients were classified into different groups based on values of feature vectors consisted of multiple VTE risk factors, then trustless groups were filtered out, and finally ML models were built on training data in unit of groups. Sensitivity and specificity of our method was compared with five ML models (support vector machine (SVM), random forest (RF), gradient boosting decision tree (GBDT), logistic regression (LR), and XGBoost) and the Padua model which was widely used in clinic.
Results
The ‘fuzzy population’ phenomenon was verified on the VTE dataset. Compared with the Padua model, the proposed model showed higher sensitivity (89.95% v.s. 84.66%) and specificity (67.86% v.s. 61.27%) on training data, and higher specificity (64.94% v.s. 63.30%) and the same sensitivity (90.24% v.s. 90.24%) on test data. Our model was more robust than other five ML models and its standard deviations of sensitivities and specificities were smaller. Besides, five ML models couldn’t simultaneously surpass the Padua’s sensitivity and specificity.
Conclusions
The proposed model achieved both higher sensitivity and specificity than the Padua model. Its robustness was better than traditional ML models. This study built a population-split-based ML model of VTE for Chinese medical inpatients by modeling the ‘fuzzy population’ and it can be applied more broadly in risk assessment of other diseases.

Published: May 2023

Blockchain technology is increasingly being used in personal data protection. Inspired by the importance of data security, this paper proposes a personal data protection mechanism based on blockchain, combined with distributed hash tables and cryptography, to enhance users' control over the data generated using web applications. This mechanism limits enterprises' data collection and uses by users without their permission, and users have complete control over the data they generate when using the web services provided by the enterprise. It is up to the user to decide whether to share their data with other organizations. This paper designs this mechanism's system model and describes the three aspects in detail: data storage mechanism, data encryption mechanism, and data trading mechanism. Among them, the data storage mechanism restrains enterprises from privately collecting users' data, the encryption mechanism ensures that the users control the generated user data, and the data trading mechanism enables users to decide to which organizations to trade their data. Then, use the Stackelberg game to simulate the revenue sharing between users and service providers in data trading, as comparison to the current scheme, this one provides 31%, 561%, and 19% more income for the service provider when there are 1000 users. Finally, it designs and implements an application platform to reflect the practical significance of this research..
“Renewable Energy Consumption and Economic Growth: Evidence from a Panel of Top 20 Countries”
Authors: Nosheen Misbah , Iqbal Javed , Ahmad Shehzad
Published: May 2023

Many nations have been working hard in recent years to adopt clean and non-conventional energy sources, unlike carbon-based power sources which have implications for economic development. To analyze the impact of renewable energy consumption on the sensitivity of economic growth amongst the top 20 renewable energy users, this study employs data from 20 countries. For the years 1990 to 2021, a sample of nations is chosen. Using Pesaran's universal diagnostic test, we address cross-sectional dependency in panels. The results show that traditional inputs of production, including renewable and renewable energy resources consumption, contribute favorably to economic growth in the studied nations over the long term. Long-term production elasticities regarding renewable energy are positive in many of the examined nations, according to results from single country time series. The study's findings show that renewable energy is a critical component of these countries' economic expansion and that these countries are on the track for long-term stable growth. The significant policy conclusion in this respect is that governments, international organizations, and energy planners should collaborate to adopt renewable arrangement policies across nations. Furthermore, policymakers in these nations need to adopt renewable energy legislation based on incentives to enhance resource efficiency.
Robust fingerprint recognition approach based on diagonal slice of polyspectra in the polar space
Authors: ALAOUI El Mehdi ISMAILI
Published: May 2023

Although fingerprint recognition is a mature technology and nowadays commercial state-of-the-art systems can be successfully used in a number of real applications, not all the problems have been solved and the research is still very active in the field. This paper presents a new approach for estimating the shift and rotation parameters between fingerprint images stored in the dadabase that operates in the third-order frequency-domain measure called the auto-bispectrum, which, allows us to estimate the shift and the rotation separately. The diagonal slices and their spectra of auto- and cross-bispectrum are proposed. The rotation parameters are estimated from the remaining polar sampled the third-order spectrum using cross-correlation, and then, after compensating for rotation, we may easily estimate the translational component, e.g., by using phase correlation.Experimental evidence of this performance is presented, and the mathematical reasons behind these characteristics are explained in depth. We compare our approach in a simulation to other frequency-domain fingerprint recognition algorithms. We find that our algorithm can better estimate shift and rotation parameters than the other methods.
Labor force participation of married women in urban India: A cross sectional analysis
Authors: Thakur Jyoti
Published: May 2023

Labor force participation of women in urban India remained stagnated at around 18% since 1980s. Against the conventional understanding, significant progress in female education, extraordinary reductions in fertility rates, and great economic growth has not led to improvement of labor force participation among women in India. This paper attempts to provide an insight into the complex nature of labor force participation of women in urban India. Using the unit level data of NSS quinquennial rounds and PLFS, this paper analyses the labor force participation of urban married women - firstly, the gender gaps in urban labor markets and changes over a period of time; secondly, trends and patterns of married women’s labor force participation from 2004-05 to 2018-19; and thirdly, a cross examination across age, level of education, occupation, work status. Lastly, the paper investigates the activity engagement of out of labor force women belonging to different education levels.

Authors: Główczyński Patryk , Dębski Paweł , Dębska-Janus Małgorzata , Badura-Brzoza¹ Karina
Published: May 2023

Background: Ego-resiliency could play a protective role, especially in stressful situations. Such a situation is certainly the period of the COVID-19 pandemic. The beginning of the pandemic period have been a source of significant stress for many people. Students, especially of medical faculties, were one of the social groups that could be particularly affected by the reorganization of everyday functioning. Effective coping with stress during this period could have been important for minimizing its negative effects.
Aim: The aim of the study was to assess ego-resiliency as a factor enhancing life satisfaction and a protective factor against symptoms of anxiety and depression in a group of health students during COVID-19 pandemic.
Methods and Material: The study was conducted in the period from October 2020 to June 2021. The study group included 362 students of the medical faculty and 249 students of the Academy of Physical Education (APhE).
The Ego Resiliency Scale (ER89-R12), the Life Satisfaction Scale (SWLS) and the Anxiety and Depression Scale (HADS) were used in the study. Among the statistical methods, the Mann-Whitney U test and Spearman's rank correlation coefficient were used.
Results: In the study group, medical students obtained the average score of 34.96±5.19 points and 36.49±5.22 points for students of the APhE was obtained in the ER-89-R12, the difference was statistically significant (p=0.003). In the SWLS, the mean score was 23.65±5.9 points for medical students and 22.35±5.67 points for students of the APhE, the difference was also statistically significant (p=0.005). In the assessment of anxiety, medical students obtained an average of 8.43±4.34 points and students of the APhE 7.60±4.27 points, the difference was statistically significant (p=0.012). In the assessment of depression, medical students achieved 5.10±3.77 points and students of APhE obtained about 4.77±3.26 points, the difference was not statistically significant. There were significant, negative correlations in the scope of the results obtained in the ER-89-R12 with the results of anxiety and depression, and positive correlations with the results obtained in the SWLS scale for both groupS.
Conclusions: Life during the pandemic was assessed by students of pro-health faculties as moderately satisfactory. The severity of symptoms of anxiety and depression correlated negatively with life satisfaction. Ego-resiliency may be a factor enhancing life satisfaction and may be a protective factor against anxiety and depression symptoms.

Published: May 2023

Secondary treated tannery wastewater (STTWW) is high in COD with value ranges from 264 mg/L to 275 mg/L also, the total suspended solids value was 164. The total nitrogen calculated was 33.2 mg/L. Cyanobacteria and microalgae are efficient bioremediators as well as significant biomass producers with loads of bimolecular content such as carbohydrate, lipid, protein which can be used for the production of value added products(VAPs). Simple tubular photobioreactors were made for mass culturing both cyanobacteria and microalgae. Cyanobacteria had higher amount of protein (0.58 mg/L) at 100% STTWW at pH 7 and at light intensity of 1000 lumens, carbohydrate (1801.4 mg/L), chlorophyll (6.6303 mg/L) 100% STTWW at pH 7 and at light intensity of 1000 lumens. Lipid was higher at 40% STTWW when compared to microalgae the remediation efficiency of cyanobacteria was better than microalgae. Cyanobacteria reduced COD reduced upto 94 % Overall this study depicts that cyanobacteria is more efficient in bioremediation and biomass production.
Analgesic effect of oral paracetamol 1000 mg/ibuprofen 400 mg, paracetamol 1000 mg/codeine 60 mg, paracetamol 1000 mg/ibuprofen 400 mg/codeine 60 mg, or placebo on acute postoperative pain: a single-dose, randomized, and double-blind study

Purpose Combining analgesics with different mechanisms of action may increase the analgesic efficacy. The multidimensional pharmacodynamic profiles of ibuprofen 400 mg/paracetamol 1000 mg, ibuprofen 400 mg/paracetamol 1000 mg/codeine 60 mg, and paracetamol 1000 mg/codeine 60 mg and placebo were compared. Methods A randomized, double-blind, placebo-controlled, parallel-group, single-centre, outpatient, and single-dose study used 200 patients of both sexes and homogenous ethnicity after third molar surgery (mean age 24 years, range 19–30 years). Primary outcome was sum pain intensity over 6 h (SPI). Secondary outcomes were time to analgesic onset, duration of analgesia, time to rescue drug intake, number of patients taking rescue drug, sum pain intensity difference (SPID), maximum pain intensity difference, time to maximum pain intensity difference, number needed to treat, prevent remedication and harm values, adverse effects, and patient-reported outcome measure (PROM). Results Analgesia following ibuprofen and paracetamol combination with or without codeine was comparable. Both were better than paracetamol combined with codeine. Secondary variables supported this finding. Post hoc analysis of SPI and SPID revealed a sex/drug interaction trend in the codeine-containing groups where females experienced less analgesia. PROM showed a significant sex/drug interaction in the paracetamol and codeine group, but not in the other codeine-containing group. Especially females reported known and mild side effects in the codeine containing groups. Conclusion Codeine added to ibuprofen/paracetamol does not seem to add analgesia in a sex-mixed study population. Sex may be a confounding factor when testing weak opioid analgesics such as codeine. PROM seems to be more sensitive than traditional outcome measures. ClinicalTrials.gov June 2009 NCT00921700
Opening of Cx43-formed hemichannels mediates the Ca2+ signaling associated with endothelial cell migration
Authors: Espinoza Hilda , Figueroa Xavier F.
Published: May 2023

Endothelial cell migration is a key process in angiogenesis. Progress of endothelial cell migration is orchestrated by coordinated generation of Ca2+ signals through a mechanism organized in caveolae. Connexins (Cx) play a central role in coordination endothelial cell function, directly by cell-to-cell communication via gap junction and, indirectly, by the release of autocrine/paracrine signals through Cx-formed hemmichannels. However, Cx hemichannels are also permeable to Ca2+ and Cx43 can be associated with caveolin-1, a structural protein of caveolae. We proposed that endothelial cell migration relies on Cx43 hemichannel opening. Here we show a novel mechanism of Ca2+ signaling in endothelial cell migration. The Ca2+ signaling that mediates endothelial cell migration and the subsequent tubular structure formation depended on Cx43 hemichannel opening and is associated with the translocation of Cx43 with caveolae to the rear part of the cells. These findings indicate that Cx43 hemichannels play a central role in endothelial cell migration and provide new therapeutic targets for the control of deregulated angiogenesis in pathological conditions such as cancer.
Effect of low dissolved oxygen concentration on structure of regenerated passive film of Ti-6Al-4V alloy under continuous wear
Authors: Du Xinyu , Shi Wei , Xiang Song , Tan Yuanbiao
Published: May 2023

Tribocorrosion is one of the most common forms of failure of biomedical titanium alloys. As the passive film of titanium alloy is highly dependent on oxygen conditions, the passivation behavior and the microstructure of the passive film of Ti-6Al-4V under tribocorrosion in 1 M HCl with a low dissolved oxygen concentration (DOC) were studied by means of electron probe microanalysis (EPMA), Ar-ion etched X-ray photoelectron spectroscopy (XPS), focused ion beam (FIB) milling and HRTEM. The results showed that the protective ability of the regenerated passive film decreased sharply under low DOC. Structural characterization indicated that Ti atoms occupied more metal lattice points in the regenerated passive film and that the high dislocation density in the deformed layer caused by wear facilitated the diffusion of Al and V. Finally, the first-principles calculation showed that Al had the minimum vacancy formation energy.

PCOS (polycystic ovary syndrome) is an important cause of infertility in women of child birthing age. It was confirmed granulosa cells were associated closely with the process of anomalous follicle formation and ovulation in PCOS. The apoptosis of granulosa cells in PCOS patients is significantly low but the growth is high, which cause accumulation granulosa cells, leading to polycystic ovaries. Non-coding RNAs was demonstrated involving in PCOS, and we found high hsa_circ_0043533 in PCOS. A series of experiments were carried out to investigate the role of hsa_circ_0043533 in PCOS and the mechanism within. Knockdown of hsa_circ_0043533 promoted apoptosis and restrained migration, proliferation, and viability of KGN cells. The regulation of hsa_circ_0043533 on miR-409-3p/BCL2 axis and key EMT (Epithelial-mesenchymal transition) markers was discovered. And the hsa_circ_0043533/miR-409-3p/BCL2 axis was regulated by metformin. This project revealed novel insights into the molecular mechanisms of granulosa cell proliferation and apoptosis in PCOS, demonstrated the new molecular pathogenesis of PCOS.
Was Technologien ermöglichen könnten - Zur Bedeutung Assistiver Technologien für die Lehrer:innenbildung

Die kürzlich verstorbene Behindertenrechtsaktivistin Judy Heumann beschreibt die Bedeutsamkeit digitaler Medien im Sinne Assistiver Technologien (AT): „For most of us, technology makes things easier. For a person with disabilities, it makes things possible” (Edyburn, 2020, S. 11). Zur gleichberechtigten aktiven Teilhabe am Unterricht und damit an Bildung benötigen manche Schüler:innen spezielle Hilfsmittel. Assistive Technologien bieten Optionen der Partizipation (Fisseler, 2020) und lassen sich aufgrund des Fokus auf das Individuum von Barrierefreiheit und Universal Design weitestgehend abgrenzen. Der Beitrag beschreibt den Einsatz von Assistiven Technologien im schulischen Umfeld sowie die Optionen der Implementation im schulischen Alltag. Die einerseits hoch eingeschätzte Relevanz von Assistiven Technologien (Edyburn, 2020) geht gleichzeitig mit einer geringen Implementation in der Schule einher (Bouck & Long, 2021). Diesem Mangel sollte mit einer Lehrer:innenausbildung begegnet werden, die Kompetenzen hervorbringt, die die Lehrkräfte in einem transdisziplinären Team den Einsatz von Assistiven Technologien planen lässt. Der Vorschlag für ein Seminarkonzept für die erste Phase der Lehrer:innenbildung wird abschließend dargelegt.
 
Abstract
The recently deceased disability rights activist Judy Heumann describes the importance of digital media in terms of assistive technologies (AT): "For most of us, technology makes things easier. For a person with disabilities, it makes things possible" (Edyburn, 2020, S. 11). Some pupils need special aids in order to participate actively in lessons and thus in education on an equal footing. Assistive technologies offer options for participation (Fisseler, 2020) and can be largely distinguished from accessibility and universal design due to the focus on the individual. The article describes the use of assistive technologies in the school environment as well as the options for implementation in everyday school life. The highly rated relevance of assistive technologies (Edyburn, 2020) is accompanied by a low level of implementation in schools (Bouck & Long, 2021). This deficiency should be countered with teacher training that produces competences that allow teachers to plan the use of assistive technologies in a transdisciplinary team. The proposal for a seminar concept for the first phase of teacher education is presented in conclusion.

The composition of mackinawite
Authors: Rickard David
Published: June 2023

The composition of a mineral is a defining characteristic. The various compositions listed for mackinawite in current mineralogical databases and reference books, such as Fe(Ni)S and Fe1+xS, are both wrong and misleading. Statistical analyses of over 100 mackinawite compositions reported over the last 50 years show a mean composition of Me1.0S where Me = Fe + Co + Ni + Cu. Mackinawite is stoichiometric FeS. As with many sulfide minerals, Ni-, Co-, and, possibly, Cu-rich varieties occur in addition to the simple iron monosulfide. These varieties are best referred to as nickelian mackinawite, cobaltian mackinawite, and cupriferous mackinawite. The results confirm that these metals substitute for Fe in the mackinawite structure rather than being contained in the interstices between the Fe-S layers. Most compositional data on mackinawites derive from electron probe microanalyses of small grains in magmatic/hydrothermal associations. The result means that there is no dichotomy between the composition of ambient temperature synthetic mackinawite (which is supposed to be equivalent to sedimentary mackinawite) and mackinawites from higher temperature associations. The correct representation of the composition of mackinawite has implications for a wide swathe of fundamental science, including the origin of life, the genesis of magmatic ore deposits, the provenance of meteorites as well as industrial applications such as water treatment and steel corrosion. The stoichiometric formulation permits the mackinawite formula to be balanced electronically using conventional Fe and S ionic species. It also enables simple, balanced chemical equations involving mackinawite.

Published: May 2023

Chitosan reacts with amino acids and hydrolyzed whey proteins to produce biologically active complexes that can be used in functional foods. The research objective was to obtain chitosan biocomposites with peptides and amino acids with improved antioxidant and sensory properties.

The research featured biocomposites of chitosan and succinylated chitosan with whey peptides and amino acids. The methods of pH metry and spectrophotometry were employed to study the interaction parameters between polysaccharides and peptides, while colorimetry and spectrophotometry served to describe the amino acids content. The antiradical effect was determined by the method of fluorescence recovery. Pure compounds and their complexes underwent a sensory evaluation for bitterness.

Chitosan and succinylated chitosan formed complexes with whey peptides and such proteinogenic amino acids as arginine, valine, leucine, methionine, and tryptophan. The equimolar binding of tryptophan, leucine, and valine occurred in an aqueous chitosan solution (in terms of glucosamine). Methionine appeared to be the least effective in chitosan interaction, while arginine failed to complex both with chitosan and succinylated chitosan. Chitosan and succinylated chitosan biocomposites with peptides and leucine, methionine, and valine proved to be less bitter that the original substances. The samples with arginine maintained the same sensory properties. Chitosan complexes with tryptophan and peptides increased their antioxidant activity by 1.7 and 2.0 times, respectively, while their succinylated chitosan complexes demonstrated a 1.5 fold increase.

Chitosan and succinylated chitosan biocomplexes with tryptophan and whey protein peptides had excellent antioxidant and sensory properties. However, chitosan proved more effective than succinylated chitosan, probably, because it was richer in protonated amino groups, which interacted with negatively charged amino acids groups.

The study offers the analysis of pragmatic function actualization through ‘umbrella’ elements of transdisciplinary intermediary terminological systems of cognitive linguistics and discourse studies. The purpose of the study is the analysis of specific cogniogenerative features of pragmatics as regards the elements in question in borderline types of discourse. The study employs complex methodology incorporating hermeneutic, discourse, definition and component analyses. Dialectical correlation of mental structures formed along with detailing and differentiation of knowledge components, and their further representation in the verbal information flow is carried out not only on the basis of the initial generally accepted deobjectification (in nuclear components), but also involves consituational formants of a specific area of the information-knowledge continuum. Such a permanent flow of illocutions for objectification and perlocutions for deobjectification of actualized components of transterminological meaning forms a special area of cognigenerative pragmatics, which provides a constant reflexive transformation of invariant structures into potentially conventionalized signs of individual terminology. Within the framework of its intellectual argumentative impact, cognitive-generative nature of transterm pragmatics contributes to the explication and intensification of the key methodological principles of a concept or theory. It also enhances modification of the conceptual and conceptual space of the recipient areas, the change in the mechanisms for integrating the modes of consideration of the studied phenomena of one discipline or direction to another and the growth of transdisciplinarity degree. The study deals with the delimitation of transdisciplinary areas of information-knowledge continuum, fosters dissymmetric features of subject- object-subject pragmaticon space of borderline areas, and proves the primary character of cogniogenerative basis when realizing the pragmatic function of transterms and quasi-terms.

Changing realities of modern life, the emergence of new professions, concepts steadily leads to the search for appropriate nominations. As a rule, for these purposes, the language borrows a new word or updates a long-known one. It is natural to assume that the actualization of an already existing lexeme will introduce a number of changes both at the level of semantics of an already established concept and at the syntagmatic features of lexemes, which may be due to the requirements for the nomination of modern realities, as well as axiological components included in these “requirements”. This article presents the results of a psycholinguistic experiment aimed at identifying the modern perception of the lexemes master, mistress, as well as their activation within a given context. In order to determine the modern seminal composition, the authors compare the semes presented in the key explanatory dictionaries of the Russian language with the semes identified during the experiment. Based on the results obtained, the authors come to the conclusion that the change in modern realities, the popularization of feminitives lead to a certain transformation of the seminal structure of lexemes.

Published: May 2023

The most pressing issue of modern terminology is the issue of its phraseologization and ambiguity. The work is aimed at finding out the availability and types of meaning transfer of the components in business English idioms with the Adjective as the first component of a phraseological unit and identifying their ability to variations. The object of the study is business English phraseological terms containing an initial adjectival component in their structure. The subject of the study is the type of meaning transfer in the component composition of phraseological units and the ability of phraseological units to variations within the frames of PU-term identity. In the study and analysis of business phraseology of a selected structural area, both macro-paradigmatic methods of linguistic research and non-paradigmatic methods and techniques of linguistics were used. Of particular importance for our study were the proposed by A. V. Kunin method and procedures of phraseological identification, methods of phraseological analysis and description. The following methods also served as a reliable scientific basis for the study of business terminology in the designated phraseological space: the method of structural analysis, the method of component analysis, the method of onedimensional modelling of phraseology. In the research some other methods were employed: methods for analysing the definitions of monolingual and explanatory dictionaries and methods of quantitative analysis. As a result of the research, two sub-types of meaning transfer in PU-term components were found out and to name them, correspondingly, two terms were introduced into meta-language of phraseology.

Published: May 2023

F. V. Bulgarin’s novel “Pyotr Ivanovich Vyzhigin” (1831), which takes place against the background of the Patriotic War of 1812, can be considered a forerunner of “War and Peace” by L. N. Tolstoy. It drew first a rather negative criticism. The French edition, published almost immediately after the Russian one, in 1832, included lengthy comments by journalist and literary critic E.-J. Héreau, which have not yet attracted the attention of researchers. It is the purpose of this paper to examine them. Far from the quarrels of the Russian literary scene, Héreau was relatively free from prejudices and passions. On the other hand, his being French could in some cases distort his perception of recent events affecting both France and Russia. Héreau’s comments, many of which contain references to specific historical works and sources, are examined using biographical, historical-cultural, historical-genetic and comparative methods. As the French critic addressed mainly the French public, ignorant of the realities of Russian life, he gave them all sorts of information: basic notions about Russia; judgments about the moral character of Russians; criticism of Bulgarin’s interpretation of some episodes of Napoleon’s Russian campaign. Héreau appears to share in many respects the skepticism of Russian critics. Like them, he seems to regret the fact that the two storylines of the novel, historical and fictional, only occasionally intersect. However, Héreau was more concerned with questions of plausibility. In general, he paid more attention to the historical storyline, criticizing Bulgarin for using Ph. de Ségur as his main source of information.

The emergence of new educational digital platforms and tools entails the need to adapt to new realities and increasingly use them in teaching. This article describes the concepts of digital resources and tools used in teaching oriental languages. Hindi language is considered as an example. It is suggested that digital tools simplify language learning and change the process of perception. Arguments for expanding and popularizing the use of digital tools in Hindi language learning and teaching are then presented. Studies showing that the use of digital tools leads to cognitive and linguistic changes in students are reviewed. The methodology includes a description of the features of using digital tools in language teaching and highlighting positive and negative experiences in practice. It concludes by discussing the implications for language education in the digital age, particularly for learning Hindi with digital tools.
JAPANESE VERB “NARU”: KEY TO UNDERSTANDING OF JAPANESE MENTALITY
Authors: Latysheva Svetlana I. ,   Sophia University

The connection between language and culture, specifically how the grammatical and lexical constructions of a language manifest the peculiarities of a nation’s culture, has long been researched. In Japan, one such grammatical construction of interest is the verb “naru”. There is a commonly held thesis that the use of this word strongly reflects the Japanese worldview and value system. Hence, considering how it is translated by speakers of other languages can be one way in which to consider the different perspectives they may hold. For the most part, Japanese researchers believe that there are two important camps of thought, either translating “naru” with a word close in meaning to the Russian “stanovitsya ; stati” (to become) or with a verb similar to the Russian “delati ; sdelati” (to do). In this paper, the author analyzes 28 variants of the use of the verb “naru” in Japanese and variants of its translation into Russian. The study concludes that only in 6 out of 28 cases, the translation of this verb using the Russian verb “stanovitsya–statj (to become)” is adequate. In response to these findings, the author hypothesizes that the frequent use of the verb “naru” in the Japanese context is meant to emphasize the importance placed on how the state of a person or the surrounding world has changed. In contrast, when placed into the Russian context, emphasis is given to action and the actor performing it. By attempting to explain these linguistic differences, we are able to make grounded assumptions about the perspectives and values held by the speakers of these two languages.

The article presents a fragment of the large-scale international study aimed at investigating the Russians and Vietnamese self- and mutual perceptions embedded in language and culture. In order to discriminate the cultural difference in the content of the notions designated by the quasi-equivalent lexemes in the two languages, the authors attempt to analyze one of the common characteristics of Russian and Vietnamese “self-portraits”. The notion of hospitality (гостеприимство/hiếu khách) was examined using corpus data. The SketchEngine and two built-in web corpora, ruTenTen11 and VietnameseWaC, were utilized for automatic construction of thesauri of this notion. It was shown that the sets of semantic components that describe the studied lexical unit demonstrate certain degree of incongruity and provide additional information about Russian and Vietnamese “self-portraits” that include quasi-equivalent lexis.
FUNCTIONAL MODELS OF ELEMENTARY DISCURSIVE UNITS IN RUSSIAN ESPORTS COMMENTARY
Authors: Mikulinskiy Artyom D. ,   HSE University
Published: May 2023

The paper is devoted to the issue of the local structure modeling of the eSports commentary spoken genre on an example of the Dota 2 computer discipline. ESports commentary is a spontaneous and creative speech aimed at describing of what is happening on the computer-gaming field. The main factors that force us to study it are the high popularity, the influencing nature of speech, as well as the lack of scientific attention. A theoretical and methodological framework of the study contains the elements of the structural and cognitivediscursive approaches in linguistics. The key research methods are language modeling, analysis of the local discourse structure in the cognitive perspective and quantitative analysis with regard to the corpus-based approach. The statistics were calculated for the sample with the total volume of 41 minutes and 30 seconds. The speeches belong to 14 Russian eSports commentators; they were delivered in 2017–2019. As a result, we have obtained a set of relevant patterns that represent characteristics of typical elementary discursive units (syntagmas) in the Dota 2 eSports commentary. These include a quick pronouncing, boundary pauses absence, frequent nuclear accent presence and embodiment of nouns and verbs. One part of the statistics represents general features of the Russian spoken discourse and human consciousness (e. g. the frequent use of absolute pauses); the other part correlate with a specificity of the situation in which the commentary is produced (e. g. the frequent use of short structures).

Object of the study is focused on the identification of the socio-cultural archetypes as a fundamental component of the image policy of the Rostov region on the texts of excursions. Research methods provide a synergetic approach and include hypothetical-deductive method, the comparative method, the descriptive method, the method of translation analysis, the method of contextual analysis, as well as the case method, the method of “brainstorming”. In our study, the evolution of interdisciplinary research allowed us to verify specific directions of studying the concept of “branding” of the region: firstly, from a tourist perspective, secondly, taking into consideration the convergent context of cultural genotype phenomena and archetypes, and thirdly, basing on the fundamental paradigm of knowledge of anthropocentric linguistics. In the course of the analysis, two groups of students studying Chinese and Arabic focused on the intensification of certain research trajectories on the basis of historical texts about the Rostov region. In the course of the study, we identified five main research trajectories including historical, geographical, geopolitical, industrial and modernist images which are characterized by using specific socio-cultural archetypes. The task of the guide-interpreter was to prepare the texts of the excursions, taking into account the contiguous identity and proximity of the socio-cultural archetypes of nations, so that the text would thereby reveal for the recipient (tourist) a high index of cultural and genetic involvement, a natural coefficient of accessibility and acceptance of the brand book text. The final product of the study was the writing of a brandbook for the Rostov region, aimed at Chinese and Arab tourists.
LINGUISTIC AND PRAGMATIC POTENTIAL OF ENGLISH-LANGUAGE ENVIRONMENTAL INTERNET MEMES
Authors: Pavlova Elena B. ,   Peoples’ Friendship University
Published: May 2023

The study deals with English-language Internet memes which communicate environmental issues. The material for the study was taken from Reddit, which is used to share topical memes on the Internet. The study analyses the linguistic and pragmatic potential of English-language environmental Internet memes and describes their visual pattern and verbal component. It is shown that after reframing, the visual template of viral Internet memes becomes a means of attracting attention to environmental issues. While keeping the same visual template, new lines, captions, and headings referring to environmental issues can be added to the verbal template; in some cases, environmental Internet memes are created specifically to explain the negative consequences of human economic activity or to evaluate environmental stunts. The author determines the set of relevant strategies and tactics based on the lingvopragmatic model, characterizes the verbal and non-verbal means ensuring their implementation. It is found that dominant strategies are the strategies of drawing attention to environmental issues, informing; argumentation; intimidation; creating a comical effect; development of a stereotype of environmental behaviour, which are implemented by tactics of focusing attention, reducing the situation to an absurdity, and negative prediction. Considering the identified communicative strategies, the typology of environmental Internet memes is proposed, and five main linguopragmatic types are identified: informing, persuasive, intimidating, humorous, ironic-sceptical. The relevant linguistic means to implement communicative tactics in English-language environmental Internet memes are colloquial vocabulary, idioms, professional vocabulary (environmental terms), synonyms, antonyms, metaphors, imperatives, present participle, colloquial syntactic constructions, expressive syntactic means: antithesis, question-answer constructions, anaphora, epiphora, and ellipsis.
