En la Sierra de Huimanguillo, Tabasco, México, aún persiste un fragmento de vegetación en el «Cerro de las Flores», reconocido por algunos investigadores como selva alta perennifolia y por otros como bosque mesófilo de montaña. Representa el único relicto mejor conservado de vegetación arbórea en la zona y es el punto de continuidad entre los corredores biológicos «Humedales Costeros-Sierra de Huimanguillo» y «Selva Maya-Zoque». Usando imágenes 'Spot' (2015) se delimitó una superficie de 5,782.34 hectáreas que incluye todo el 'Cerro de Las Flores' dividiéndolo en área de conservación y área de amortiguamiento. Usando el continuo de elevaciones mexicano 3.0 del INEGI se encontró que las altitudes en el área fluctúan entre 157 msnm y hasta 1,039 msnm. Es necesario implementar estrategias que permitan la conservación de la vegetación primaria y secundaria aun existente en la zona, creando una franja de amortiguamiento al 'Cerro de las Flores'.

Authors:   Bunin Yelets State University, Selemeneva O.A.
Published: March 2023

In the article, the author considers the problem of clip thinking of a postmodern era person through the prism of advertising communication. The aim of the work is to identify and systematically describe the features of the verbal part of creolized messages in the format of direct and native advertising, which are focused on the addressee with fundamental changes in the cognitive style and the mechanism of perceiving linear text. The sources of the research are the Russian editions of periodical international glossy magazines of various thematic, age and gender orientation published in 2018-2021. The methods of studying the language material are descriptive-analytical, communicative-pragmatic, comparative methods and the method of contextual analysis. As a result of the study, a set of specific tools and techniques were identified that ensure the retention of the recipient’s attention with fragmentary mosaic perception, the speed of decoding information, its compression, segmentation, visualization. It is noted that the verbal component of direct advertising messages tends to minimize and is distinguished by the primitivization of the syntactic structures, the constant switching of the language code, and the regular inclusion of hashtags. The verbal component of advertising texts in the native advertising format is characterized by an increased volume and hybridity of nature, uses language units that create short-lived emotionally expressive and aesthetically perfect images, means that cause positive associations and ensure switching the recipient’s attention (intertexts, bisubstantial sentences, question-answer complexes, perceptual vocabulary, etc.). The author comes to the conclusion that further research of forms of mass communication in the context of the problem of clip thinking should choose the path of interdisciplinarity, joint activity of psychologists, philologists, cultural scientists, philosophers and other specialists.

Published: March 2023

The article deals with developing an approach to studying the mechanism of interaction of secondary emotions and semantically similar concepts-scenarios in two groups. The authors analyze results of questioning the teenagers comparing two different levels of coding information. The aim of the work is to develop a methodology for establishing a conceptual correspondence between a secondary emotion as a concept and a concept-scenario, which is based on cognitive-associative connections. The novelty of the work lies in the fact that for the first time the mechanism of forming a cognitive construct, including secondary emotions and semantically similar concepts-scenarios, is analyzed, and the levels of conceptual correspondence are established in the groups of hearing and with impaired hearing respondents. The methods to fulfill the tasks are: the method of questioning, which helps to collect reliable data in each group of subjects; the method of quantitative counting and ranking, which helps to bring the result to the identification of the range of values obtained; the comparison method is also used in identifying coincidences and differences in the results of two groups. The methodological algorithm of establishing a conceptual correspondence between a concept as secondary emotion and a concept-scenario is developed and consists of methods: the method of lexical analysis, the method of comparison of qualitative interactions when establishing a conceptual correspondence. Then conceptual correspondence is revealed according to three levels: complete conceptual correspondence, incomplete conceptual correspondence, lack of conceptual correspondence. The results show the main nomination of secondary emotion “fear” revealed in two groups, the situation from the past experience (concept scenario) being the same as a description connected with being at altitude. Teenagers with the 1st and 2nd degree of deafness were able to establish cognitive-association links and, therefore, showed the ability to form a cognitive construct consisting of a nominated secondary emotion as a concept and concept-scenario. The teenagers with hearing impairments of the 3rd and 4th degrees didn’t cope with the task in establishing cognitive association links, since more serious hearing impairments seem to lead to impaired formation of cognitive-association connections and, as a result, cognitive constructs. Accordingly, the formation of cognitive construct makes it possible to speak of a connection between a newly-learned phenomenon and past experience. The cognitive construct is established on the basis of the actualization of secondary emotion in two concepts. The data obtained can be used to correct and regulate cognitive-associative links between the concept and the similar concept-scenario.

Authors:   Perm National Research Polytechnic University, Enbaeva L.V.
Published: March 2023

The paper addresses the issue of instruction strategy employment in the academic discourse from the viewpoint of cognitive-discursive paradigm. The aim of the paper is to reveal discursive tactics actualizing the instruction strategy in Chemistry textbooks and compare them cross-culturally. Comparison of Russian and English Chemistry textbooks was conducted to draw a sample of discourse moves that aim to develop cognitive skills; they were analysed in order to structure the received sample. The comparative analysis resulted in the proposal of a classification of instruction tactics in accordance with the expected learning outcomes. It comprises two types of instruction tactics: subject-specific and meta-subject. The paper highlights a few differences in the application of instruction tactics in Russian and English Chemistry textbooks. The differences involve variation of verbal expression and position characteristics as well as functional differences. One possible application of research results might be connected with enhancing textbook writer’s awareness of instruction strategy and tactics employment with the view of expected learning outcomes. The proposed classification could be applied in teaching materials design. In summary, cross-cultural comparison of textbooks can be beneficial to our further understanding of academic discourse and cognitive development.
SECONDARY INTERPRETATION AS A FACTOR OF FIGURATIVE MEANING
Authors:   Uzbek State World Languages University, Yuldashev A.G.
Published: March 2023

This article deals with English and Uzbek zoonyms which are used in anthropomorphic area as one of the factors of secondary interpretation. The article is aimed at pointing out the formation of conceptual anthropomorphic metaphor in creating a linguistic worldview as a result of secondary interpretation. Research methods used are as following: comparative analysis, cognitive modeling. The researcher shows that the above-mentioned units with secondary interpretation are expressed by metaphorical cognitive models as ANIMAL - HUMAN BEEING. Their secondary interpretation reveals emotive-evaluative characteristics of the concept human being: concerning “character of a person”, “status of a person”, “age of a person”, “the behavior of a person”, “life experience of a person”, “appearance of a person”, which is closely connected with linguacultural aspect. The author concludes that secondary interpretation of figurative meaning of zoonym metaphors is an effective tool for recreating the conceptual worldview.
FIXED PHRASE SCHEMES AS THE «RESULTS» OF GRAMMATICALIZATION PROCESS
Authors:   Southern Federal University, Melikyan V.Y. , Melikyan A.V. ,   Southern Federal University
Published: March 2023

The article analyzes the fixed phrase schemes in the cognitive aspect as the «results» of grammaticalization process. It has been established that the phraseologization phenomenon is directly associated with grammaticalization. The fixed phrase schemes grammaticalization on the level of signifier is the secondary use of a free syntactic structure; and on the level of signified it is the utmost generalization of the productive base semantics to the level of a categorical seme: «statement», «negation», «estimation», etc. The result of the fixed phrase schemes grammaticalization is the phraseological meaning, which is stable, invariable, unmotivated by the grammatical meaning of the syntactic construction, by which it is generally represented, and idiomatic. The phraseological meaning is grammatical: it does not nominate the speech subject but points out the means of its interpretation. The phraseological meaning serves as a typical proposition component, functioning as a predicate. The fixed phrase scheme in the entirety of plain of expression and plain of content is the grammatical cliché; we can insert diverse content here and get intrinsic predetermined result; the new grammatical indicator, the means of typical propositions representation; the secondary conceptualization and categorization sign; the grammaticalization result. A set of typical propositions realized by the fixed phrase schemes and their frequency have been identified. It was also stated that the fixed phrase schemes usually implement several typical propositions - the main and the optional ones, which allow them to express «strong» emotional-volitional communicative reactions. They do not only name typical situation but also express emotional attitude, replacing two syntactic constructions at once.

The article examines the potential of the educational text as the basis for the formation of knowledge base and the possibility of identifying the specifics of cognitive projections in the individual consciousness. We made an attempt to consider the features of the manifestations of individual consciousness based on the analysis of cognitive projections of the educational text, to analyze cognitive projections depending on the type of text. The results of an experiment conducted among students of the 11th grade (Nur-Sultan, Republic of Kazakhstan), according to the method of supplement based on the material of educational text, are presented. It is established that the middle and initial filling of gaps contributes less to the understanding of the message in its entirety. The use of the supplement technique in the assimilation of textual educational information allows us to determine how accessible the educational text is for students’ perception and understanding; the use of the supplement in the educational process gives not only a correct idea of the general intelligibility of the text, but also helps achieve the acquisition of speech skills by students in the construction of coherent speech. The practical significance of the article is determined by the possibility of using the described experimental method in other research papers.

The study explores the distribution of deictic words and gestures in multimodal explanatory discourse. To proceed, we compile the corpus of speech and gesture in which the experiment participants are explaining the difference between close synonyms. The study develops the method of modelling deixis as a discourse frame of reference which allows to identify objects and situations via pointing at them. We show that two frames of reference - egocentric and allocentric - help explore the discourse semantics of deictic words and gestures on the same grounds using the coordinates of two frames which are the distance from the speaker (closer to the speaker / farther from the speaker) and the type of communicative situation in discourse (the internal communicative situation / the external communicative situation). The results reveal that the differences between the two frames of reference may not always be explicit in the semantics of deictic words, still they may appear in the use of gesture types.
SECONDARY INTERPRETATION OF LANGUAGE STRUCTURES IN MIGRANTS’ POETRY AND PROSE
Authors:   Derzhavin Tambov State University, Riabykh E.B. , Vinogradova S.G. ,   Derzhavin Tambov State University
Published: March 2023

The article deals with issues related to metaphors in poetry and prose of migrants through the prism of multiculturalism. The authors argue that in cognitive perspective metaphors emerge within the framework of secondary linguistic interpretation and conceptual derivation as its underlying process. Taking into account memory peculiarities and working space of a poet or writer, possible procedural variants of metaphor production are proposed. It is stated that metaphors in poetry and prose of migrants are created being based on national / conventional and unique / individual patterns of their formation with reference to certain contextual factors that correlate with dominant constructs of poets and writers’ linguistic consciousness. Significant is the idea of integrating the accumulated contextual knowledge in the aspect of cognitive matrix, as well as possible variation in the content of the matrix model from the mundane to the expert representation of knowledge in the process of metaphorical interpretation of the world migrant poets and writers live or lived in.

Post chemotherapy retroperitoneal lymph node dissection (PC-RPLND) in non-seminomatous germ-cell tumours (NSTGCTs) is a complex procedure. We evaluated whether 3D computed tomography (CT) rendering and their radiomics analysis help predict resectability by junior surgeons. The ambispective analysis was performed between 2016-2021. Prospective group (A) of 30 patients undergoing CT were segmented using 3D slicer software while retrospective group (B) of 30 patients were evaluated with conventional CT (without 3D reconstruction). CatFisher’s exact test showed a p-value of 0.13 for group A and 1.0 for Group B. Difference between proportion test showed a p-value of 0.009149 (IC 0.1-0.63). Proportion of correct classification showed a p-value of 0.645 (IC 0.55-0.87) for A, and 0.275 (IC 0.11-0.43) for Group B. Furthermore, 13 shape features were extracted: elongation, flatness, volume, sphericity, surface area, among others. Performing logistic regression with the entire dataset, n=60, the results were: Accuracy: 0.7, Precision: 0.65. Using n=30 randomly chosen, the best result obtained was Accuracy: 0.73, Precision: 0.83, with a p-value: 0.025 for Fisher's exact test. In conclusion, the results showed a significant difference in the prediction of resectability with conventional CT versus 3D reconstruction by junior surgeon versus experienced surgeon. Radiomics features used to elaborate an artificial intelligence model improve the prediction of resectability. The proposed model could be of great support in a university hospital, allowing to plan the surgery and to anticipate complications.

The COVID-19 pandemic measures have negatively impacted education worldwide via travel restrictions, student visas, and physical attendanc,e among many other fac-tors. As one of the first places to impose strict pandemic measures and one of the last places to lift the measures, Mainland China provided a unique venue to investigate the effect of public health pandemic control policies on tertiary education. Considering the large portion of international students in medical schools and the higher susceptibility to the pandemic measures due to the natural synergy with teaching hospitals, medical schools can be an early forefront indicator of the impact of the pandemic on tertiary education. We surveyed 513 participants international medical students from Wen-zhou Medical University’s school of international studies in 2019 and 2022 about their satisfaction and demographic and cultural adaptation parameters. We found that the pandemic restrictions did not generally impact student satisfaction. Further analyzing the associated parameters, we found teaching satisfaction to be independent of age (P=.159), years in China (P=.896) and Chinese Level (P=.577) in the medical university. Teaching satisfaction is associated with the region of origin (P <0.001), acceptance of local social norms (P <0.001), satisfaction with the core values of Chinese culture (P <0.001), acclimatization to life in China (P <0.001), can easily make Chinese friends (P <0.001) among other factors. The findings of this study provide an understanding of the effects of pandemic measures on tertiary education satisfaction and other factors that can aid in international student satisfaction.

Microbial biofilms cause several environmental and industrial issues, even on the human health. Although they have represented a threaten due to their resistance to antibiotics, there are currently no approved antibiofilm agents for clinical treatments. The multi-functionality of antimicrobial peptides (AMPs) including the antibiofilm activity and their potentialities to target multiple mi-crobes motivated the synthesis of AMP relatives for developing antibiofilm agents for clinical purposes. Antibiofilm peptides (ABFPs) have been organized in databases that allowed the building of prediction tools which have assisted in the discovery/design of new antibiofilm agents. However, the complex network approach has been explored yet as an assistant tool for this aim. Herein, a kind of similarity networks, called the Half-Space Proximal Network (HSPN) is applied to represent/analyse the chemical space of the ABFPs aimed to identify promising scaf-folds for the development of next generation antimicrobials, able to target both planktonic and biofilm microbial forms. Such analyses also considered the metadata associated to the ABFPs such as origin, other activities, targets, etc. in which the relationships were projected by multilayer networks called metadata networks (METNs). From the complex networks mining, a reduced but informative set of 66 ABFPs representing the original antibiofilm space was extracted. This subset retained from the most central to atypical ABFPs, having some of them, desired properties for developing next generation antimicrobials. So, this subset is advisable for assisting the search/design both new antibiofilm/antimicrobial agents. The provided ABFP motifs list, dis-covered within the HSPN communities, is also useful for the same purpose.

Publications on the selected topic in the PubMed and E-library databases (n = 63), which are widely available and meet the analysis inclusion criteria (two-stage and five-stage selection). Scientific studies included as follows: meta-analysis - 5, review - 19, systematic review - 3; clinical trials - 36. Results. The most common long-term symptoms after a new coronavirus infection in children include shortness of breath (12.8-68.0%), headache (17.1-75.0%) and fatigue (10.8-98.0%). Cardiovascular disorders and disorders of the nervous system, and mental disorders, registered in the long-term period in the pediatric population, contributed to the development of follow-up algorithms, models of rehabilitation and monitoring, which is especially important for children with cardiac pathology. Conclusion. The undertaken analysis of studies available in the public domain made it possible to determine the most common symptoms of the post-COVID syndrome, and also showed the importance of studying this problem and the need for a longer follow-up of children who have had a coronavirus infection.

Significance. In 2020, many Russians faced an increased need for medicines to treat COVID-19 and its complications, as well as economic hardship due to the crisis caused by the pandemic. The purpose of the study. To identify key factors that determined the Russian households’ spending on medicines and dietary supplements during the pandemic. Material and Methods. The study used Russian Longitudinal Monitoring Survey - National Research University “Higher School of Economics” samples of households and adults for the year 2020. We employed regression models to estimate the probability of purchasing medicines and dietary supplements, and family expenses on medicines and dietary supplements, depending on medical factors, healthy lifestyle factors, socio-economic and demographic factors. Results. The probability of buying medicines and dietary supplements and the household expenditures were higher in families with the disabled, individuals with multimorbidity, with self-reported poor health, and with pensioners. High expenditures on medicines and dietary supplements were observed in families which members visited doctors on a regular basis. Both the probability and expenditures on medicines and dietary supplements rose with the increase in average per capita income. The presence of children under 14 years in the family was associated with a decrease in expenditures on medicines. Smoking, overweight and sports were significant contributors to expenditures on medicines and supplements, although their relative contributions were quite small. Private health insurance did not affect expenditures on medicines. Residents of the Northwestern Federal District spent significantly more on medicines compared to residents of other districts. Conclusions. Expenditures on medicines and dietary supplements in 2020 were largely explained by the following two key factors - people suffering from two or more chronic conditions in the family and the average per capita income. Other household factors, although significant, contributed much less to the decision to spend on medicines and dietary supplements. Public provision of medicines especially during economic crisis can be improved by supporting poor households and including patients with multimorbidity into drug reimbursement programs and thus expanding the number of its beneficiaries. Scope of application. The study results can be used to improve policy on pharmaceutical provision of the population.

Implementing a Novel Organic Acid Matrix Stimulation to Successfully Remove Formation Damage: Case Studies, Iraq and Ecuador Oilfields

Published: March 2023

This paper discusses the efficiency of design, application, and pumping schedule of organic acid treatments used for mature fields in Iraq. Due to challenging completion schematics, an enhanced fluid placement method consisting of coiled tubing (CT), nitrogen, and a fluidic oscillator tool (or combination) is presented.

By the time a well completion is achieved, oil production for most wells begins to decrease because of formation damage caused by fines migration, clay swelling, scale deposition, emulsions, organic deposits, or previous unsuccessful hydrochloric acid (HCl) or HCl/hydrofluoric acid (HF) stimulation treatments. A matrix stimulation/acidization using a tool that enables pumping the treatment, either as near as possible to or reciprocating across the perforations, is necessary to help remove formation damage, enhance recovery, and increase oil production (producer wells) or water injection (injector wells).

Matrix stimulation treatments were performed for both producer and injector wells for an Iraq field, demonstrating enhanced conductivity results and increasing oil production up to 2000 BOPD over the last production rate or improving the water injectivity rate by 10000 BWPD. In addition, for those wells in which an electrical submersible pump (ESP) was installed, it was necessary that the selected stimulation fluids did not adversely affect the internal components of the ESP. To reach this goal, analysis of the following parameters was performed: mineralogy, regain permeability test, temperature, fluids properties, rock properties, and formation damage. Based on the analysis, customized designs assisted by software simulations were developed to determine the most effective treatment selection.

This paper describes how well information and correct analysis, and design can help to develop a customized optimal intervention strategy, identify the best solution to remove the formation damage, and deliver value added to the operators.

The world largest 3D DAS-VSP survey was completed through the joint OBN and 3D DAS-VSP data acquisition project. By using the airgun sources of an ongoing high-density OBN data acquisition project within the offshore of Abu Dhabi, the high-density OBN data and 3D DAS-VSP data were acquired simultaneously in a total of 13 wells. All the wells have armored optical cable preinstalled outside the production or injection tubing and the optical cable was strapped on the tubing with clampers at 10 m spacing. The data processing workflow includes deblending, noise removing, first break picking, VSP FWI to invert the velocity model and least-squares multiple RTM imaging processing. The multi-well 3D DAS-VSP data will be used to generate high-accuracy and high-resolution 3D structure image with a higher number of folds, and the attributes of the amplitude preserved imaging data can be used to identify fluid in the reservoir formation and tracing the reservoir layer distribution around the boreholes. DAS-VSP data can also been used to enhance borehole-driven 3D seismic data processing significantly. The DAS-VSP data can also be used for AVO analysis, reservoir fracture prediction, and anisotropy analysis and reservoir characterization. At the meantime, the armored optical cable is located near or inside the reservoir, the 3D DAS-VSP data will be used to extract formation average and interval velocity, deconvolution operator, absorption, attenuation (Q value), anisotropy parameters (η, δ, ε) as well as enhanced the OBN seismic data processing including velocity model calibration and modification, static correction, deconvolution, demultiple processing, high frequency restoration, anisotropic migration, and Q-migration.
