The Relaxation Effects in the Preisach - Néel Model of Patterned Media
Authors: Cazacu Ana , Rotărescu Cristian , Bodale Ilie
Published: February 2022

In this paper, we present the calculation of thermal magnetic viscosity based on numerical simulations of relaxation isotherms curves for a Stoner–Wohlfarth ensemble. The Stoner–Wohlfarth particles is described by two equilibrium states and thermal activation is done by overcoming the energy barrier. For simulations we have used a new Preisach type model for Patterned Media, which takes into account the effects of time and temperature. The magnetization of the system is treated using the Preisach Model for Patterned Media with bimodal interactions field distributions. We have simulated relaxation curves starting from different points on the negative region of the descending branch of the major hysteresis loop and from the obtained data we evaluated the thermal fluctuation field. The results obtained for the linear energy barrier were compared with the non-linear energy barrier.
Necessity of Budget Deficit Under Economic Growth in Monopolistic Competition
Authors: Tanaka Yasuhito
Published: February 2022

The aim of the paper is to show, using a simple two-period overlapping generations model in which goods are produced solely by labour in a monopolistically competitive industry, that a continuous budget deficit (including the interest payments on government bonds) is necessary to achieve and maintain full employment under economic growth driven by technological progress. Since the budget deficits must be continuous, it might be better if they were financed by seigniorage rather than government debt. Since the budget deficit due to the issuance of government bonds puts pressure on fiscal expenditures in the amount of interest payments, a budget deficit of the same size due to seigniorage is a more effective use of the budget. It will also be shown that to achieve full employment from a recession with involuntary unemployment the extra budget deficit is necessary.

Authors: Grzesiak Hanna
Published: February 2022

Osoby z niepełnosprawnościami, choć stanowią znaczą część społeczeństwa nie są popularnym tematem filmowym. Kwestie dotyczące seksualności tej grupy społecznej rzadko są podejmowane nie tylko w filmach, ale także w dyskursie publicznym. W społeczeństwie wciąż panują liczne stereotypy, według których osoby te są aseksualne lub hiperseksualne. Szczególnie napiętnowane są kobiety z niepełnosprawnościami, którym często odbiera się prawo do bycia matką oraz żoną lub partnerką. Celem artykułu jest zwrócenie uwagi na seksualność kobiet z niepełnosprawnością fizyczną oraz dokonanie analizy filmów wyemitowanych w ostatnich latach, które poruszają tę niezwykle ważną problematykę.

У рабочих завода свинцовых аккумуляторов установлен повышенный в крови и моче уровень свинца, а также продуктов перекисного окисления липидов, отмечено снижение активности ключевых ферментов антиоксидантной системы, нарушение лейкоцитарно-клеточного, гуморального и клеточного звеньев иммунной системы. Таким образом, повышение антиоксидантного статуса, детоксицирующих и защитных функций организма посредством обогащения рациона сухими белковыми смесями на осно ве кобыльего молока благоприятно сказалось на состоянии здоровья и повышении качества жизни обследуемых. Ежедневное употребление белковой смеси на основе кобыльего молока, обогащенной комплексом иммунных факторов, витаминами-антиоксидантами, пре- и пробиотиками, а также макро- и микроэлементами, благоприятно сказалось на обменных процессах работников перерабатывающей отрасли промышленности, включая выведение свинца из организма, повышение защитных, иммунных, антиоксидантных и детоксицирующих функций организма. Полученные результаты могут служить основанием для широкого внедрения смесей в питании рабочих не только контактирующих с тяжелыми металлами в процессе производства свинцовых аккумуляторов, но и работников горнодобывающей отрасли промышленности в качестве как специализированного, так и лечебнопрофилактического питания.

The workers of the lead battery plant have found elevated levels of lead in blood and urine, as well as products of lipid peroxidation, a decrease in the activity of key enzymes of the antioxidant system, a violation of the leukocyte-cell, humoral and cellular parts of the immune system. Thus, increasing the antioxidant status, detoxifying and protective functions of the body through enrichment of the diet with dry protein mixtures based on mare’s milk has a benefi cial effect on the health status and improving the quality of life of the subjects. Daily consumption of a protein mixture based on mare’s milk, enriched with a complex of immune factors, antioxidant vitamins, pre and probiotics, as well as macro-micronutrients, favorably affected the metabolic processes of workers in the processing industry, including elimination of lead from the body, increase of protective, immune, antioxidant and detoxifying body functions. The results obtained can serve as the basis for the widespread use of mixtures in the nutrition of workers not only in contact with heavy metals in the production of lead batteries, but also for workers in the mining industry as both specialized and medical and preventive nutrition.

What is the Smallest Zeolite that Could be Synthesized?
Authors: Dhabal Debdas , Bertolazzo Andressa , Molinero Valeria
Published: February 2022

Zeolites with a few unit cells are promising as catalyst and adsorbents. The quest to synthesize the smallest zeolites has recently resulted in 4 to 8 nm nanozeolites, about 2 to 4 unit cells, obtained with a smart choice of structure directing agent. These findings pose the question of what is the smallest zeolite that could be obtained by hydrothermal synthesis. Here we address this question using molecular simulations and thermodynamic analysis. The simulations predict that amorphous precursors as small as 4 nm can crystallize zeolites, in agreement with the experiments. We find that interfacial forces dominate the structure of smaller particles, resulting in size-dependent compact isomers that have ring and pore distributions different from open framework zeolites. The instability of zeolites smaller than 4 nm precludes a classical mechanism of nucleation from solution or through assembly of small nanoslabs.

The (Z) and (E) isomers of an extended tetraphenylethylene-based chromophore with optimized two-photon induced luminescence properties are separated and functionalized with water-solubilizing pendant polymer groups, promoting their self-assembly in physiological media in the form of small, colloidal stable organic nanoparticles. The two resulting fluorescent suspensions are then evaluated as potential two-photon luminescent contrast agents for intravital epifluorescence and two-photon fluorescence microscopy. Comparisons with previously reported works involving similar fluorophores devoid of polymer side chains illustrate the benefits of the later functionalization regarding the control of the self-assembly of the nano-objects, and ultimately their biocompatibility towards the imaged organism.
Fast and accurate quantum mechanical modeling of large molecular systems using small basis set Hartree–Fock methods corrected with atom-centered potentials
Authors: Prasad Viki Kumar , Otero-de-la-Roza Alberto , A. DiLabio Gino
Published: February 2022

There has been significant interest in developing fast and accurate quantum mechanical methods for modeling large molecular systems. In this work, by utilizing a machine-learning regression technique, we have developed new low-cost quantum mechanical approaches to model large molecular systems. The developed approaches rely on using one-electron Gaussian-type functions called atom-centered potentials (ACPs) to correct for the basis set incompleteness and the lack of correlation effects in the underlying minimal or small basis set Hartree-Fock (HF) methods. In particular, ACPs are proposed for ten elements common in organic and bio-organic chemistry (H, B, C, N, O, F, Si, P, S, and Cl) and four different base methods: two minimal basis sets (MINIs and MINIX) plus a double-ζ basis set (6-31G*) in combination with dispersion-corrected HF (HF-D3/MINIs, HF-D3/MINIX, HF-D3/6-31G*), and the HF-3c method. The new ACPs are trained on a very large set (73832 data points) of non-covalent properties (interaction and conformational energies) and validated additionally on a set of 32048 data points. All reference data is of complete basis set coupled-cluster quality, mostly CCSD(T)/CBS. The proposed ACP-corrected methods are shown to give errors in the tenths of a kcal/mol range for non-covalent interaction energies and up to 2 kcal/mol for molecular conformational energies. More importantly, the average errors are similar in the training and validation sets, confirming the robustness and applicability of these methods outside the boundaries of the training set. In addition, the performance of the new ACP-corrected methods is similar to complete basis set DFT but at a cost that is orders of magnitude lower, and the proposed ACPs can be used in any computational chemistry program that supports effective-core potentials without modification. It is also shown that ACPs improve the description of covalent and non-covalent bond geometries of the underlying methods and that the improvement brought about by the application of the ACPs is directly related to the number of atoms to which they are applied, allowing the treatment of systems containing some atoms for which ACPs are not available. Overall, the ACP-corrected methods proposed in this work constitute an alternative accurate, economical, and reliable quantum mechanical approach to describe the geometries, interaction energies, and conformational energies of systems with hundreds to thousands of atoms.

Published: February 2022

Amaç: Kolonoskopi sırasında bulunan poliplerin çoğu 5 mm’nin altındadır. Polipektomi teknikleri endoskopistler arasında çok değişkendir ve endoskopistin tercihine göre belirlenmektedir. Bu çalışmada diminutif polip (DP) olarak adlandırılan, ≤5 mm poliplerde, jumbo forseps (JFP) ve soğuk snare (CSP) ile yapılan polipektomilerin tam rezeksiyon oranları ve komplikasyonlar yönünden karşılaştırılması amaçlanmıştır. Materyal ve Metot: Kliniğimizde herhangi bir nedenle kolonoskopi yapılan ve ≤5 mm polip saptanan hastalar; JFP ve CSP grubu olarak iki gruba randomize edildi. Polipektomi yöntemleri komplikasyon ve rezeksiyon açısından karşılaştırıldı. Bulgular: Toplam 100 polipektomi işlemi (JFP grubu=50 ve CSP grubu=50) analiz edildi. Ortalama hasta yaşı 59,1±11,2 yıldı ve 54'ü (%54) erkekti. Hastaların demografik özellikleri ve polip karakteristikleri gruplar arasında benzerdi. DP'ler için genel tam rezeksiyon oranı, JFP ve CSP grupları arasında önemli ölçüde farklı değildi (%90'a karşı %82, P=0,38). ≤3 mm poliplerde polipektomi süresi CSP grubunda anlamlı olarak uzundu (p=0,008). CSP grubunda %4 minör kanama izlendi ve 4 polip (%8) çıkartılamadı. Komplikasyon oranı CSP grubunda anlamlı olarak yüksek saptandı (p=0,01). Sonuç: ≤5 mm kolorektal poliplerin eksizyonunda, rezidü açısından JFP ve CSP yöntemlerinin birbirlerine üstünlük sağladıkları gösterilmemiştir, ancak JFP yöntemi ile komplikasyon oranları daha düşük saptanmıştır.

Published: February 2022

Objective: It was aimed to evaluate the etiological relationship between the SARS-CoV-2 virus and subacute thyroiditis (SAT). We also wanted to point out the fact that these two entities may have similar clinical features.
Materials and Methods: During the 4th month of the Coronavirus disease-19 (COVID-19) pandemic in our country; five patients were referred to our clinic for neck ultrasonography (USG) with a suspected diagnosis of SAT based on clinical and laboratory features. Past medical history, contact history, and COVID-19 Polyerase Chain Reaction (PCR) test results of these cases were evaluated.
Results: Subfebrile fever, sore throat, burning sensation in the throat, difficulty in swallowing were the presenting symptoms of the patients. All cases had abnormal thyroid hormone values and elevated erythrocyte sedimentation rate/C-Reactive Protein (CRP) values. USG showed increased thyroid gland volume in four patients. Hypovascularized heterogeneous hypoechoic patchy areas in thyroid parenchyma were observed in all patients without discrete nodules. Ultrasound elastography revealed parenchymal heterogeneity and stiffness. Low-dose non-contrast chest computerized tomography (CT) findings was normal with negative Polymerase chain reaction (PCR) test results in patients.
Conclusion: Subacute thyroiditis, which is often accused by viral agents in etiology, may also be associated with SARS-CoV-2. The similarity of clinical and laboratory findings between subacute thyroiditis and COVID-19 infection may pose diagnostic challenges.

Published: February 2022

Numerous offices are currently utilizing AI calculations to settle on high-stake choices. Deciding the correct choice unequivocally depends on the accuracy of the info information. This reality gives enticing motivations to lawbreakers to attempt to mislead AI calculations by controlling the information that is encouraged to the calculations. Then, conventional AI calculations are not intended to be protected when going up against startling data sources. In this exposition, we address the issue of antagonistic AI; i.e., we will likely form safe AI calculations that are hearty within the sight of loud or adversarial controlled information. Ill-disposed AI will be additionally testing when the ideal yield has a mind boggling structure. In this paper, a sign cannot concentrate is on antagonistic AI for anticipating organized yields. To start with, we build up another calculation that dependably performs aggregate classification, which is an organized expectation issue. Our learning strategy is efficient and is defined as a raised quadratic program. This procedure verifies the expectation calculation in both the nearness and the nonappearance of an enemy. Next, we explore the issue of parameter learning for hearty, organized forecast models. This strategy builds regularization capacities dependent on the impediments of the foe. In this exposition, we demonstrate that strength to antagonistic control of information is proportionate to some regularization for huge edge organized expectation, and the other way around. A customary enemy consistently either does not have enough computational capacity to structure a definitive ideal assault, or it doesn't have sufficient data about the student's model to do as such. In this manner, it frequently endeavors to apply numerous irregular changes to the contribution to an expectation of making a leap forward. This reality suggests that on the off chance that we limit the normal misfortune work under antagonistic clamor, we will acquire power against unremarkable enemies. Dropout preparing takes after such a commotion infusion situation. We infer a regularization technique for huge edge parameter learning dependent on the dropout system. We stretch out dropout regularization to non-straight parts in a few unique ways. Experimental assessments demonstrate that our procedures reliably beat the baselines on various datasets. This exploration work incorporates recently distributed and unpublished coauthored material.

Three Essays On The Effects Of Credit Default Swaps
Authors:   , Nguyen Binh
Published: February 2022

This thesis investigates the effect of credit default swaps on firm behaviour. A credit default swap (CDS) is an insurance contract under which buyers make periodic payments over the contract's life to insure against credit events related to the underlying entities. As an efficient tool for lenders or bond investors to hedge the credit exposures associated with their investments in a firm while maintaining their control rights, the market for CDSs has developed quickly over the last two decades. The impact of this new but fast-growing credit derivative market has attracted considerable attention from financial researchers.

This thesis contains five chapters. Chapter 1 presents a brief introduction to CDSs and the research questions. Chapter 2 discusses the origins of CDS, the definition of CDS, the initiation of CDS through the over-the-counter market, the effect of CDS on creditor-debtor relationship and data sources for CDS inception.

Chapter 3 investigates how initiating a credit default swap (CDS) affects firm risk. Using the firm value volatility as a measure of firm risk, I document that firm risk decreases following the commencement of CDS trading. The CDS effect on firm risk is less pronounced for firms with more financial constraints and firms with a greater discrepancy between their bond and their CDS market. My findings reveal a significant impact of financial innovation on firms' behavior, which supports the ``empty creditor'' hypothesis. I also document that reducing expenditure levels on hiring and investment is one channel through which this negative impact occurs.

Chapter 4 empirically investigates the impact of credit default swap (CDS) inception on corporate debt maturity profiles. I show a positive relationship between CDS inception and debt maturity dispersion. This positive relationship is stronger when the credit market condition is tighter, and more pronounced for less financially constrained or higher-quality firms. My results are robust to the endogeneity of CDS trading. The findings reveal a significant effect of financial innovation on the focal firm's debt structure.

Chapter 5 examines the impact of credit default swap (CDS) inception on debt specialization. I find that firms with CDS traded on their debts tend to increase their debt specification levels. CDS inception reduces the likelihood of a strategic default, so firms specialize in fewer debt types to decrease the probability of inefficient liquidation by creditors. The positive relationship between the CDS inception and debt specialization is more pronounced for firms facing higher expected bankruptcy costs. My results are robust to the endogeneity of CDS trading and the alternative measure of debt specialization.

Chapter 6 presents a summary of the findings in Chapter 3, Chapter 4, and Chapter 5 and concludes the thesis.
A humanitas romana como chave de leitura do pensamento político de Hannah Arendt
Authors: Salellas Bosch Alfons C.
Published: February 2022

Este artigo procura oferecer uma forma de introdução distinta à teoria política de Hannah Arendt. Em primeiro lugar, mostramos como a reflexão arendtiana pode ser remitida a uma ideia ou a uma experiência – totalitarismo, política, natalidade, mundo, pluralidade – sem pretender estabelecer qualquer redução monística de sua obra. A continuação, desenvolvemos o conceito romano de humanitas, a partir do texto de Arendt sobre Lessing, e a noção grega de amizade política como porta de entrada ao pensamento arendtiano. Finalmente, ressaltamos a influência decisiva de Karl Jaspers e sugerimos que Hannah Arendt aponta para a possibilidade de outra filosofia fora dos parâmetros metafísicos e ontológicos da tradição, um filosofar distinto que leva inscrito o selo da contingência e a marca da humanitas.
MACINTYRE’S AFTER VIRTUE: A PHENOMENOLOGICAL READING
Authors: Bernacchio Calleb
Published: February 2022

This essay offers a phenomenological reading of Alasdair MacIntyre’s After Virtue. It is intended to both illustrate the similarities between MacIntyre’s mode of argumentation in this work and the early Heidegger’s method of phenomenological destruction, and to highlight the potential fruitfulness of a deeper engagement between phenomenology and MacIntyre’s work. MacIntyre’s critique of modern moral philosophy, like Heidegger’s destruction, turned upon the groundlessness of abstract concepts separated from the experiential and social context in which they were originally at home. Drawing upon Heidegger’s phenomenology allows one to better understand MacIntyre’s critique as well as the role of his notion of a practice as a corrective to these tendencies.

Published: February 2022

Communication skills are extremely important for the tourism industry; they form an integral part of most tourism activities. Using English, as the international lingua franca, is an essential part of these skills, especially for international tourism. Saudi Vision 2030 places a high importance on international tourism as a driving force for economic growth. Since the inception of the Saudi Vision 2030, the tourism industry in Saudi Arabia, along with its workforce, has been growing substantially. Therefore, designing English language teaching materials for the tourism industry workforce in Saudi Arabia is a necessity. The current study firstly aimed to analyze the English language communicative needs of the Saudi tourism workforce, and then propose an English for Specific Purposes (ESP) model for teaching English based on their needs. A nation-wide survey was designed and distributed to sixty-two male and fifteen female workers serving in the Saudi tourism industry to determine their English language communicative needs. Listening and speaking were found to be highly important to their profession, in particular understanding instructions and requirements and providing details about touristic attractions. Reading and vocabulary were found more important than writing and grammatical accuracy. The study concludes with a proposal of an ESP teaching model to meet the English language communicative needs of the tourism workforce in Saudi Arabia.
ECOLOGICAL ASPECTS OF OPTIMIZED APPLICATION OF PLANT PROTECTION PRODUCTS
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, FEDORENKO VYACHESLAV F.
Published: February 2022

Within the “From Field to Counter” Strategy framework, the European Parliament calls for a review of the procedure for the admission of plant protection products (PPP) in the EU. The aim is to strengthen control over the PPP use and reduce their use. The development of energy- and resource-saving agrochemical technologies for the PPP use implies designing monodisperse spray devices for specific chemicals, specifying their consumption rates per unit area, and selecting compatible spray equipment and relevant agricultural technologies. The elaboration of spray technology requires a fundamentally new approach to its testing and determining the dispersed composition of spray droplets. To elaborate an innovative methodology for optimizing the operation of spraying devices based on the dispersive analysis of spray droplets, the authors have developed and manufactured a test bench that provides a representative aerosol sampling. Express analyzers of spraying quality have been developed, made in the form of cards with dimensions 90 by 40 mm or tape 40 mm wide and 3 m long, impregnated with a solution of potassium hexacyanoferrate (III) at a concentration of 5…7%. A computer program has been made for counting and ranking spray drops in a real-time mode. The article presents study results on the optimization of several parameters: the consumption rates of the products and the hydraulic medium, the density (concentration) of the power fluid droplets on the surface of the treatment object, the dispersed composition of the spray droplets (the droplet size, the degree of productivity polydispersity and the possibility of adjusting the technological process parameters). The developed experimental complex and the technology of experimental testing of spraying devices will facilitate comparative tests of spraying devices.

Modern transport and technological machines operate under the seasonality conditions of agricultural operations and significant energy loads. Universal joints of unequal velocity, being part of mechanical power transmissions, work under adverse conditions and limit equipment reliability. It was established that the temperature mode of the bearing assemblies of the universal joints affects the wear rate of their working surfaces. When the temperature in the friction zone increases due to mechanical operation and heating from the environment and adjacent heat sources, boundary friction and temperature conditions exceeding the level of material self-tempering occur. As a result of research, the universal joints (RU199508) were designed to ensure the intensification of cooling its bearing units directly in the maximum heat generation zone during the universal joint operation. Numerical simulation was performed according to the thechinque of calculating radiators for a universal joint with a cross K 040 GOST 13758-89 on needle bearings No. 804704 K5. The results showed the size of the outer surface area that is sufficient for its cooling. When the maximum values of the fracture angle of the universal joint, torque, angular velocity, and efficiency of 0.99 are combined, its bearing units are effectively cooled. It has been found that if the efficiency of the bearing assemblies is less than 0.952, their surface is no longer sufficient to provide efficient cooling and maintain thermal balance conditions in the friction zone. The use of the radiator can increase the heat transfer area by 19%. The radiator ribs fixed on the side surfaces of the yoke eyes with a thickness of 2 mm and a distance of 4 mm and a total area of 166.1 cm2 will ensure the operability of the bearing units. It will remain satisfactory even if their efficiency decreases to 0.943 as a result of mechanical wear.

Objetivo: Identificar las características clínico-epidemiológicas que presentan los pacientes que se atendieron por presentar síntomas de COVID-19 en la UMF No 40 del Instituto Mexicano del Seguro Social situado en Reynosa, Tamaulipas. Material y métodos: Se llevó a cabo un estudio observacional, transversal y descriptivo, empleando información recogida en el formato emitido por la Secretaría de Salud de México en un total de 323 pacientes sospechosos. Además, se estimaron pruebas de asociación y diferencia de medias. Resultados: Se encontró que, del total de encuestados, el 53.9% fue diagnosticado como positivo mediante la prueba Reacción de Cadena de Polimera-sa (PCR). La comorbilidad que más se presentó en este grupo fue la obesidad (32.8%), seguida de la hipertensión (23%) y la diabetes (17.8%). Los hallazgos de las pruebas de asociación indican que no existe una relación entre poseer determinada comorbilidad y dar positi-vo a la prueba. En tanto que la prueba de diferencia de medias señala que el número de síntomas entre los pacientes positivos suele ser mayor respecto de los negativos. Y se confirma que las personas con mayor edad suelen estar más predispuestos a ser contagiados res-pecto de los más jóvenes. Conclusiones: Cada población responde de manera distinta a una enfermedad, por ello, los estudios epidemio-lógicos nos ayudan a entender el comportamiento de una patología en un contexto especifico, por lo cual, es necesario continuar generan-do estudios a nivel local.

COMMUNICATIVE AND PRAGMATIC LEVEL OF VERBAL MANIPULATION
Authors: Sorokina Lina
Published: February 2022

This article focuses on the study of communicative, pragmatic and gender aspects of verbal manipulation, throwing light on its manifestation in Modern English dialogical discourse. Dialogical manipulative situations have been revealed and classified on the basis of their discursive communicative and pragmatic characteristics. The analysis of differences in men’s and women’s manipulative utterances has been performed.

The article analyzes the discursive nature of the verbal manipulation, establishes the models of its implementation in English dialogical discourse taking into account the gender aspect. The basic structural model of the manipulative situation in the dialogical discourse consists of such components: an addresser, an addressee, a message, an addressee’s and addresser’s worlds, communicators’ visionary worlds, a social situation, each of which forms its own level.

The basic means of the “addresser-addressee” level are communicative roles, which are divided into standard and initiative. The latter is subdivided into active and passive roles. Women's manipulative speech is characterized by initiative roles of care, benevolence and interest. For men, such a communicative behavior is possible only in connection with the role of an expert or the standard communicative role (a son, a brother, a husband). Women also use the role of an expert, but in combination with the standard roles of their sister, girlfriend, and mother. The analysis of communicative roles allowed differentiating between cooperative and conflictive types of the manipulator.
TRANSLATING RELIGIOUS POETRY BY A NON-NATIVE – A TRANSLATOR’S PERSPECTIVE (BASED ON THE TRANSLATION OF THE “AKATHIST HYMN TO OUR LADY IN HOLM ICON GLORIFIED” FROM UKRAINIAN INTO ENGLISH)
Authors: Dobzhanska-Knight Nataliia
Published: February 2022

The article deals with the peculiarities of translation of an Orthodox Christian poetic akathist prayer from Ukrainian into English by a native speaker of Ukrainian. The author analyses stylistic features of this type of religious discourse as well as processes involved in the translation work. The article dwells on the challenges and facilitating factors of translation. The challenges include a six-rhyme structure combined with a relatively poor selection of rhyming options, the syllable count, a system of word and sentence stresses different from Ukrainian, as well as a limited choice of vocabulary due to the peculiarities of style. The factors which facilitate the translation are also related to the stylistic features of akathist prayers which allow inversions and the use of alternative words and imagery as long as they are in sync with the style and the mood of the Orthodox hymn. The article shows which tools and procedures contribute to a successful result, in particular, rhyming dictionaries and thesauri. To secure the success of a translation performed by a non-native speaker of English, approval of the author and post-translation proofreading by a native speaker is indispensable, which includes both a clergyperson and a professional copyeditor. Consideration of all these factors will contribute to the quality of the translation.
CRITICAL THINKING AND TEACHING STYLISTIC ANALYSIS OF THE LITERARY TEXT
Authors: Ushchyna Valentyna , Darkevych Olena , Belyakov Olexander , Kozak Svitlana
Published: February 2022

The development of students’ critical thinking skills is a paramount issue of modern education globally. Notwithstanding there is no accord among the philosophers, psychologists and educators as to transferability and teachability of critical thinking skills. Our approach to this issue is twofold. In order to become independent thinkers, students should be equipped with critical thinking inventory as well as have advanced practical skills of its application. This article is an attempt to look at the problem of teaching the stylistic analysis of the literary text from the perspective of critical thinking. We discuss how by the critical reading of a literary work and applying a polycritical methodology to its analysis students enhance the high-order thinking skills – analysis, synthesis and evaluation. The present paper illustrates some before, during and after reading classroom strategies that can be utilized to encourage students to dig deeper and “read between the lines” in order to decode the message of the author, effectively interpret it and use it as a vantage point for constructing intermedial connections, self-reflection and interpretation of the real world. Progressive educators create the learning environment where freedom of thought and the dissent are equally accepted and fostered. The anchoring potential of critical thinking as a mediator between the fictional and real world and as a booster of the students’ abilities to evaluate, make an independent judgment and solve problems is viewed by us as a leverage on rote learning and copy-paste mentality as well as an instrument of establishing democratic values in education.
SEMIOTICS OF FASHIONSPEAK
Authors: Khrystych Nina
Published: February 2022

The article is devoted to the semiotics of modern fashionspeak. The semiotic sign which creates image is studied in the article. The main idea is that forming and functioning of fashionspeak is based on linguistic theories. The author proves that fashionspeak holds symbolism having the capacity to express one’s unique style, identity, profession, social status, and gender or group affiliation.The author leads the idea that the connection between the text and fashion should be sought in the decoding of linguistic signs that creates differences between a male and a female fashion. The male fashionspeak is represented by using the words of the semantic field “strength” while the semantic field of female fashionspeak is “beauty”. Hence, men’s image is verbalized by the Nouns “strength”, “power”, “confidence”, “reliability” etc. while women’s image is verbalized by “pretty”, “beautiful”, “attractive”, “awesome”, “lovely”, “gorgeous”, “glamorous”, “sexy”, “chic”, etc.The author emphasizes that DRESS CODE concept does not include only “clothes” but also some external attributes of culture such accessories, perfumes, lifestyle, hairstyles, and so on. The axiological meaning in men’s and women’s DRESS CODE can easily increase an individual’s self-significance by portraying the desirable values in accordance with their lifestyle. Therefore, the author believes that semiotics of clothes can be intentionally created.Consideration is given to the international character of fashionspeak because of many international words (jeans, pullover, jumper, Dior, Prado, Versace) and the wide use of non-verbal means of communication.
INTERTEXTUALITY IN ACTION: THE ROLE OF EXPERT ADVICE IN EVERYDAY PARENTING
Authors: V. Tovares Alla
Published: February 2022

This article explores the relationship between discourse and action by examining the role of expert advice in everyday parenting practices. Drawing upon the notions of dialogicality (Bakhtin, 1981), intertextuality (Kristeva, 1986), and repetition (Tannen, 2007) and incorporating insights from Mediated Discourse Analysis (e. g., Scollon, 1998; Scollon and Scollon, 2007; Norris and Jones, 2005), this work analyzes instances in which the actions of parents in three American families can be traced back to various public texts on parenting. Such relationship between text and action is identified as intertextuality in action (Author, 2005, 2020), or when public texts serve as resources for the verbal and non-verbal everyday actions of parents. It is further suggested that by adopting a positive, childcentered approach to parenting from literature and trained childcare professionals, parents themselves are socialized into the contemporary Discourse (Gee, 1999, 2015) of parenting. The analysis of the “repetition” of the words of experts in family (inter)actions also illuminates the dialogic relationship between the public and private spheres.
