Violation of the cooperative principle as the manifestation of “communicative sabotage” speech genre
Authors:   Saratov State University, Bots Tatyana S.
Published: April 2021

The article studies the “communicative sabotage” speech genre as a possible way of reacting to criticism in the response utterances of the presidents of Russia and the USA, V. V. Putin and B. Obama. The internal genre tactics of communicative sabotage are considered in relation to Grice’s Cooperative Principles. Both approaches are perceived as complementary in relation to each other, which allows to get a holistic perception of deviations from norms of interpersonal communication. The fact that communicative sabotage belongs to indirect communication reflects the specifics of the presidential discourse, which consists in the need to avoid inconvenient topics and to veil information in public communication with journalists. The role of communicative sabotage in solving pragmatic tasks of the president’s communication, such as the struggle for power, allows to attribute it to agonal speech genres.
Speech genre theory through the prism of modern linguistics
Authors:   Vitebsk State University named after P. M. Masherov, Maslova Valentina A.
Published: April 2021

The article deals with the status of the speech genres theory (SGT) and its contribution to the development of modern linguistics. In his polemical article Professor V. V. Dementyev argues that SGT is characterized by the wide range of research problems, a close connection with such academic domains as the theory of speech acts, colloquial studies, discourse analysis, linguistic personology and other areas that study a human and their language. This thesis does not raise objections, as the 21st century is considered to be the century of syncretism and interpenetration of sciences, which has become one of the main features of the entire post-non-classical science. This approach provides a holistic reflection on the object of study, in this case, on the language. It is called syncretism, integrity, interdisciplinarity, polydisciplinarity, transdisciplinarity. In general, these terms are synonymous, because they are based on the idea of holism of everything in the world. In this sense, SGT is in line with modern science. The thesis of V. V. Dementyev on the diffusion of genres. Diffusion can be considered as the most important trend not only in science, but also in the entire modern culture, which is shown with the help of examples. However, some statements of V. V. Dementyev’s article seem debatable: the problem of the pervasiveness of SGT in linguistics in its entirety, which can give rise to a dangerous tendency – the absorption of linguistics by SGT. Their interests do often overlap, but each of the named areas solves the problem of personal communication in a social environment in its own way, and each of them has its own subject and its own history. Today SGT cannot take into account many of the processes occurring in discourse, but this is a relatively new science with a great future.

Nordic Countries: Rational Algorithm to Overcome the Crisis
Authors: Voronov K.
Published: April 2021

A group of socially and economically prosperous North-European countries (Iceland is to be considered separately) has successfully got over the crucial phase of the 2008–2010 crisis. However, it is untimely to speak about its total overcoming. The system consequences of the crisis strike the next blow to the “Scandinavian/Swedish” model, aggravated the search for ways of sustainable development. The prospects to upgrade the northern economies and societies are not associated here with the change of actual viable models of participation in European and global division of labor. The current challenges are linked with such problems as the further accumulation of riches, increase of consumption, aging of population, growth of immigration etc. The bipolar political party system is being diluted, the struggle is aggravating between traditional parties and radical right-wing, populist parties of the “new type”, which expand their mission.
Markets Transnational Corporations in Emerging: in Search of Successful Business Model
Authors: Bereznoi A.
Published: April 2021

The article starts analysis from the recent trend of fast growing importance of emerging markets for Western TNCs and the related shifts in the geography of their foreign investment activities. Despite this visible investment boom the actual performance of many TNCs in emerging markets has not met their expectations and a number of major players have already lost enormous sums of money. The author argues that one of the main reasons is the obvious desire of Western firms to adopt their domestic business models in the new structurally different environment which is frequently rejecting them as inefficient. Special attention is given to business model definition which, according to the author’s concept, should include three fundamental characteristics: (1) mechanism of value creation and delivery to the target client group, (2) mechanism of profit generation, and (3) mode of maintaining sustainable balance between two mechanisms above on the basis of the given resources and processes and simultaneous creation of sustainable competitive advantages. An attempt is made to disclose why business models, quite successful in the developed market economies, are often failing when TNCs try to transfer them unchanged to the emerging markets. The author explores the main directions of effective business models’ re-engineering bringing them in line with the specifics of local economic environment. These include significant product adaptation and related re-orientation to the new customer segments, re-building of local supply chain, distribution, and even financial infrastructure. The author also draws attention to the new features of TNCs’ global organization emerging under the conditions of simultaneous deployment of multiple business models in various host economies.

Authors: Zharikov M.
Published: April 2021

The purpose of this article is to analyze Chinese Yuan and major international reserve currencies on the basis of particular criteria such as a currency’s use in settling cross-border trade and financial transactions. The author estimates the potential of Yuan’s convertibility and its achieving the status of an international reserve currency. The author lays out a background to assess the impact of these probabilities on stable and sustainable economic development in China itself. The conclusion is that the character of Yuan’s internationalization is strikingly different from similar examples of other currencies’ historic paths to an international reserve currency status in that it is closely controlled by the government.
The Universe of Religions in the Global Dynamics: “Traditional” and “Non-Traditional”
Authors: Rashkovskii E.
Published: April 2021

The collision of “traditional” and “non-traditional” in the present day Russian religious landscape as well as in the present day world could not be interpreted as a kind of direct confrontation between Past and Present. This collision displays its global nature connected with subtle and complicated problems of revival of seemingly obsolete archaic ideas, habits and institutions in unique post-modern conditions of social life, economy, technology, mass culture and cross-cultural interplay. It seems to be valid either for interpretation of universal religious dynamics of modern and post-modern world (including Japan, India and Latin America), or for understanding and interpretation of the present day cultural, religious and legal realities in Russia including life and status of the Russian religious minorities. Many Russian domestic problems in the field of religious matters seem to be dependent not only on unique constellations of the present day universal and domestic history, but also on certain shortages of legal, philosophical and theological background of the Russian political class as well as (partly) of intelligentsia.
Financial System Stability and Central Bank’s Reaction Function
Authors: Korzhenevskii N.
Published: April 2021

The paper argues that financial system stability has become a target variable for the Federal Reserve System, European Central Bank and the Bank of England, and monetary policy since at least 2008 has been largely driven by its consideration. The author develops a simple formal model quantifying a central bank’s typical response to a change in general volatility levels showing that this has been a statistically stable relationship, even well before the subprime crisis in the USA. The relationship can be used by practitioners in order to determine the timing or conditions appropriate to expect a policy change given central bank’s behavioristic pattern. The use of unconventional measures is considered for the post-crisis period, with short-term rate expectations brought to the forefront. Quantitative easing is perceived as one of two main tools to anchor rate expectations. It is assumed that in all cases monetary policy has been successful in achieving its immediate targets so far, and market-observed rate expectations can be deemed acceptable to achieve primary policy goals.
EU Nuclear Energy: Economics vs. Ecology
Authors: Zimakov A.
Published: April 2021

The article analyses economic roots of the recent reassessment of the role of nuclear energy in the EU with the global economic crisis as a background. Despite the huge political impact caused by Fukushima disaster the majority of EU member states don’t commit to nuclear power phase-out or to a major curb of nuclear development. This can be explained by the high economic viability of NPPs’ operation as well as by huge monetary expenses and environmental consequences associated with the phase out. Most openly this can be seen in the case of Germany.

Published: April 2021

The association between obesity and the risk of gliomas remains unclear. We sought to evaluate the potential association between general and abdominal obesity and the risk of gliomas based on a nationwide population-based cohort study of Koreans. Using data from the Korean National Health Insurance System cohort, 6,833,744 people older than 20 years who underwent regular national health examination in both 2009 and 2011 were followed until the end of 2017. We documented 4,771 glioma cases based on an ICD-10 code of C71 during the median follow-up period of 7.30 years. Individuals with a body mass index (BMI) ≥ 25.0 kg/m2 were at significantly higher risk of gliomas than those with a BMI < 25.0 kg/m2 (HR 1.08 CI 1.02-1.15). Individuals with a waist circumference (WC) ≥ 90 cm (males)/85 cm (females) also had a significantly higher risk of gliomas than those with a WC < 90 cm (males)/85 cm (females) (HR 1.16 CI 1.09-1.24). In the group with a BMI ≥ 25.0 kg/m2, individuals with abdominal obesity were at significantly higher risk of gliomas (HR 1.18 CI 1.09-1.27) than those without abdominal obesity. The role of abdominal obesity in this association was stronger in women than in men. To our knowledge, this is the first demonstration that obese people may be at higher risk of gliomas, especially centrally obese people from an Asian population with a BMI ≥ 25.0 kg/m2. Loss of visceral fat in people with abdominal obesity may reduce their risk of gliomas.
Curating and Comparing 114 Strain-Specific Genome-Scale Metabolic Models of Staphylococcus aureus
Authors: Renz Alina , Dräger Andreas
Published: April 2021

Staphylococcus aureus is a high-priority pathogen causing severe infections with high morbidity and mortality worldwide. Many S. aureus strains are methicillin-resistant (MRSA) or even multi-drug resistant. It is one of the most successful and prominent modern pathogens. An effective fight against S. aureus infections requires novel targets for antimicrobial and antistaphylococcal therapies. Recent advances in whole-genome sequencing and high-throughput techniques facilitate the generation of genome-scale metabolic models (GEMs). Among the multiple applications of GEMs is drug-targeting in pathogens. Hence, comprehensive and predictive metabolic reconstructions of S. aureus could facilitate the identification of novel targets for antimicrobial therapies. This review aims at giving an overview of all available GEMs of multiple S. aureus strains. We downloaded all 114 available GEMs of S. aureus for further analysis. The scope of each model was evaluated, including the number of reactions, metabolites, and genes.Furthermore, all models were quality-controlled using Mᴇᴍᴏᴛᴇ, an open-source application with standardized metabolic tests. Growth capabilities and model similarities were examined. This review should lead as a guide for choosing the appropriate GEM for a given research question. With the information about the availability, the format, and the strengths and potentials of each model, one can either choose an existing model or combine several models to create models with even higher predictive values. This facilitates model-driven discoveries of novel antimicrobial targets to fight multi-drug resistant S. aureus strains.

Published: April 2021

Irrational use or misuse of antibiotics, particularly by outpatients, increases antibiotic resistance. A lack of public knowledge about ‘Responsible use of antibiotics’ and ‘How to obtain antibiotics’ is a major cause of this. This study aimed to assess the effectiveness of an educational video about antibiotics and antibiotics use to increase outpatient's knowledge in two public hospitals in East Java, Indonesia. A quasi-experimental research setting was used with a one-group pretest-posttest design, carried out from November 2018 to January 2019. The study population consisted of outpatients, to whom antibiotics were prescribed, in two public hospitals in East Java, Indonesia. Participants were selected using a purposive sampling technique; 98 outpatients at MZ General Hospital in S regency and 96 at SG General Hospital in L regency were included. A questionnaire was used to measure the respondents’ knowledge and consisted of five domains, i.e. definition of infections and antibiotics, obtaining the antibiotics, directions of use, storage instructions, antibiotic resistance. The knowledge test score was the total score of the Guttman scale (a dichotomy of ‘yes’ or ‘no’ answers). To determine the significance of the difference in knowledge before and after providing the educational video and in the knowledge score between hospitals, the (paired) Student’s t-test was applied. The educational videos significantly improved outpatients' knowledge, which increased with 41% in MZ General Hospital and 42% in SG General Hospital. An educational video is a useful method to improve the knowledge of the outpatients regarding antibiotics.

Improvement of Algorithm for Formation of Orthogonal Components of Input Quantities in Microprocessor Protection
Authors: Romaniuk F. A. , Rumiantsev Yu. V. , Rumiantsev V. Yu. , Novash I. V.
Published: April 2021

The use of orthogonal components (OC) underlies  the construction of measuring elements of  modern protection and automation devices. In most microprocessor-based protections, the orthogonal component of the input signal is extracted using a discrete Fourier transform (DFT). The DFT disadvantages are its low speed, which is more than one period of the fundamental frequency, as well as the sensitivity to the free aperiodic component, which creates significant conversion errors depending on the time constant of its decay. Such a settling time of the true output signal is often unacceptable for the design of high-speed measuring devices. The paper proposes to form the OC of the equivalent signal according to the values of the cosine and sine OC of the fundamental harmonic, formed using the DFT by multiplying them by the resulting correction factor. The developed algorithm for the formation of orthogonal components of input signals in microprocessor protections is characterized by high speed in transient modes and it has wide functionality. So, the proposed digital device for forming the orthogonal components of an equivalent signal, in comparison with digital filter based on the DFT, has an increased operating speed both in the mode of occurrence of a short circuit and during the decay of the monitored signal, while maintaining the same characteristics as in the DFT in other modes. A block diagram of the proposed digital device for forming the OC of an equivalent signal has been developed, all blocks of which can be implemented on a microelectronic and microprocessor element base. A digital model of the specified device has been developed in the dynamic modeling system MatLab-Simulink in accordance with the structural diagram. As a result of the calculations, a significant (up to two times) increase in the performance of the proposed digital device for forming the OC in transient modes has been established in comparison with the shapers based on the DFT.

One of the most effective methods of treating intravascular formations at present is the use of stepped ultrasonic waveguide systems of a tubular type (concentrators-waveguides) with a hollow spherical tip, the presence of which makesit possible to supply liquid media to the dislocation zone of an intravascular formation with the aim of additional cavitation effect and as efficiently as possible. destroy intravascular formations due to vibration impact. Based on the results of the analysis on the features of the existing shaping methods for obtaining a hollow spherical tip of the concentrator-waveguide, it is advisable to use methods of plastic deformation – expansion and crimping. The paper presents results of preliminary calculations, numerical modeling and experimental studies of tip shaping processes of the concentrator-waveguide by distribution and crimping. On the basis of the finite element method in the environment of the ABAQUS software package, modeling of the expansion and crimping of a pipe billet was carried out, which has made it possible to: evaluate the stress-strain state of the deformable conical section of the billet, the change in wall thickness during the forming process and calculate the length of the billet for the design of the conical section; to establish the patterns of the influence of geometric parameters on the power modes of the distribution process; to set the parameters of the modes of forming the tip of the concentrator-waveguide by the method of distribution and crimping, which ensure the formation of the required geometry. The obtained results of preliminary calculation, numerical modeling and experimental studies of tip shaping processes of the concentrator-waveguide by distribution and crimping have similar values, which confirms the correctness of using both the method of preliminary calculation and numerical modeling in the development of the technology for manufacturing the concentrator-waveguide.
Blending Control of Trolleybus Traction and Brake Drives to Enhance Braking Efficiency of Vehicle
Authors: Safonau A. I.
Published: April 2021

The widespread use of green public transport is a priority strategy to reduce a congestion and pollution from road traffic in many cities. The trolleybus is a type of urban public electric transport, which is considered as a promising tool for  increasing the efficiency of public transport and achieving the goals of sustainable development and quality of life in the city. The operation control of service brake system and secondary brake system (braking torque of traction electric motor) is realized with the help of one pedal in the trolleybus. Thus, there are modes of joint operation for these systems during the braking process. The author has focused his main attention on the development of an algorithm for blending control of the traction electric motor and the anti-lock braking system to enhance the overall braking efficiency of a vehicle. For this purpose, a mathematical model of the trolleybus braking dynamics has been developed. Bench and road tests have been carried out on various road surfaces to determine parameters of vehicle braking efficiency and to validate the developed mathematical model. The corresponding experimental data were used to analyse the efficiency of the proposed strategy for combining the blending control of traction electric motor and anti-lock braking system of the trolleybus. As a result, the efficiency of the proposed control algorithm has been confirmed, which provides the required braking efficiency and high braking stability of the vehicle.
Spectrum Analysis of Signal in Wolfram Mathematica System
Authors: Hundzina M. A.
Published: April 2021

The purpose of this paper is a spectrum analysis of signals of various nature, construction of the signal scalogram using Morlet wavelet, modification of the scalogram to obtain a more informative graphic representation of the signal. Spectral analysis of the signal is constructed by means of the Fourier transform. A modification of the graphical representation of the result of the wavelet transform has been developed with the help of  the Mathematica system. For this, a wavelet scalogram has been used as a two-dimensional representation of the original signal. A scale has been introduced on it for the value of the signal amplitude depending on the time and period of its constituent components. This graphical representation allows us to obtain additional information about the dynamic properties of the original signal.  A modification of the representation of the original signal scalogram has been developed for a more complete spectrum analysis (determination of the period of the constituent components). The paper contains an example using a modified scalogram for the analysis of a signal containing two pulses, an audio signal and white noise. The basic wavelet in this case is the Morlet wavelet. A comparison of the scalogram, obtained using the built-in function, and the modified scalogram has been made in the paper. The disadvantage of the first scalogram is the impossibility of assessing the frequency of the signal; its advantage is the ability to assess the localization of the pulse. For a modified scalogram, the advantage is the estimation of the signal periodicity, and the disadvantage is the inaccuracy in determining the range of pulse localization. For spectrum analysis in Mathematica, it is recommended to use a combination of two approaches (using a standard built-in function to determine the localization of the pulse) and a modified scalogram (to determine the periods of the constituent components).

Background: Neonatal infection with group B Streptococcus (GBS) is still a threat to the life of fetus and mother, especially in developing countries that do not adopt a prenatal screening test policy such as Yemen. Objective: This study aimed to determine the vaginal colonization rates and antibiotic susceptibility pattern of group B Streptococcus among pregnant Yemeni women. Methods: We conducted a cross-sectional study over a four-month period involved 210 pregnant women who visited Gaza medical center (a primary health center in Sana’a city, Yemen) at the 35th to 39th gestational weeks. A vaginal swab from each pregnant woman was inoculated in Todd-Hewitt enrichment broth and after 24h incubation; the subculture on a 5% human blood agar plate was performed from inoculated Todd-Hewitt enrichment broth. All positive cultures identified as group B streptococcus were subjected to antibiotic susceptibility test using the disk-diffusion method. Results: Out of 210 recruited pregnant women, 23 (10.95%) were GBS vaginal carriers. All isolates showed no resistance to penicillin, ampicillin, levofloxacin, cefotaxime, and vancomycin. However, we observed decreased sensitivity to clindamycin (82.8%) and tetracycline (30.5%). Conclusion: Based on the study results; approximately eleven out of every 100 pregnant women were vaginal colonized by GBS in Sana'a governorate. Beta-lactam antibiotics remain the drug of choice for treatment and prophylaxis of GBS infections. Therefore, we recommend implementing a screening policy to detect GBS in Yemeni pregnant women.

Bladder cancer (BLCA) has a high rate of morbidity and mortality, and is considered as one of the most malignant tumors of the urinary system. Tumor cells interact with surrounding interstitial cells, playing a key role in carcinogenesis and progression, which is partly mediated by chemokines. CXC chemokines exert anti‑tumor biological roles in the tumor microenvironment and affect patient prognosis. Nevertheless, their expression and prognostic values patients with BLCA remain unclear. We used online tools, including Oncomine, UALCAN, GEPIA, GEO databases, cBioPortal, GeneMANIA, DAVID 6.8, Metascape, TRUST (version 2.0), LinkedOmics, TCGA, and TIMER2.0 to perform the relevant analysis. The mRNA levels of C-X-C motif chemokine ligand (CXCL)1, CXCL5, CXCL6, CXCL7, CXCL9, CXCL10, CXCL11, CXCL13, CXCL16, and CXCL17 were increased significantly increased, and those of CXCL2, CXCL3, and CXCL12 were decreased significantly in BLCA tissues as assessed using the Oncomine, TCGA, and GEO databases. GEO showed that high levels of CXCL1, CXCL6, CXCL10, CXCL11, and CXCL13 mRNA expression are associated significantly with the poor overall survival (all p < 0.05), and similarly, those of CXCL2 and CXCL12 in the TCGA database (p < 0.05). The predominant signaling pathways involving the differentially expressed CXC chemokines are cell cycle, chemokine, and cytokine-cytokine receptor interaction. Moreover, transcription factors such as Sp1 transcription factor (SP1), nuclear factor kappa B subunit 1 (NFKB1), and RELA proto-oncogene, NF-KB subunit (RELA) were likely play critical roles in regulating CXC chemokine expression. LYN proto-oncogene, src family tyrosine kinase (LYN) and LCK proto-oncogene, src family tyrosine kinase (LCK) were identified as the key targets of these CXC chemokines. MicroRNAs miR200 and miR30 were identified as the main microRNAs that interact with several CXC chemokines through an miRNA-target network. The expression of these chemokines is closely associated with the inﬁltration of six categories of immune cells. We explored the CXC chemokines superfamily-based biomarkers associated with BLCA prognosis using public databases, and provided possible chemokine targets for patients with BLCA.
