Published: April 2022

The presence of unsaturated flow in tropical lateritic soils of unknown hydromechanical behavior may lead to severe geotechnical problems. It is known that soil-water characteristic curves (SWCC) are a valuable tool to define this behavior and facilitate the suction estimation, acting on tests performed with no control of such parameter. This article aimed to determine and model the SWCC for 3 unprecedented tropical soils, in the undisturbed and the compacted conditions, from the Paraná state, located in the south of Brazil. The soils studied are one clay and two sands, all lateritic. The pressure plate and the filter paper methods were used to determine the SWCC. The samples were carved and submitted to the drying paths. Furthermore, Mercury Intrusion Porosimetry (MIP) tests were performed in samples of the studied soils in order to obtain the pore size distribution (PSD), contributing to the bimodal definition of curves and the prediction of SWCC main parameters. Both techniques (pressure plate and filter paper) were combined and the SWCC was adjusted by Gitirana & Fredlund model, which efficiently represents the shape of the traditional curves for tropical soils. Furthermore, the SWCCs were predicted by PSD and obtained satisfactory numerical fits. All SWCC presented air entry values in the macropores that are characteristic of soils as the lateritic, given that its structure was considered a key factor in the shape of the curves.
The classical solution of arbitrary smoothness for the first mixed problem for the Klein – Gordon – Fock type equation
Authors: Korzyuk V. I. , Stolyarchuk I. I.
Published: April 2022

In this paper, we consider the first mixed problem for the one-dimensional Klein – Gordon – Fock type equation in a half-strip. Meanwhile, the existence and uniqueness of a solution of arbitrary smoothness is researched. While solving this problem using the method of characteristics, equivalent second type Volterra integral equations appear. The existence of a unique solution in the class of n times continuously differentiable functions is proven for these equations when initial functions are smooth enough. Moreover, it is shown that for the smoothness of the solution of the initial problem it is necessary and sufficient that the matching conditions for the given functions be fulfilled if they are sufficiently smooth. The method of characteristics, used for problem analysis, is reduced to separating the total area of the solution on subdomains in each of them so that the solution of the subproblem is constructed with the help of the initial and boundary conditions. Then, the obtained solutions are glued in common points, and the received glued conditions are the matching conditions. This approach permits to construct both exact and approximate solutions. The exact solutions can be found when it is possible to solve the equivalent Volterra integral equations. Otherwise, one can find an approximate solution of the problem either in analytical or numerical form. Along with this, when constructing an approximate solution, the matching conditions turn out to be essential, which must be taken into account when using numerical methods for solving the problem.

Published: April 2022

The main trends in the field of improving thermal spraying processes for ceramic coatings formation is, along with enhancement of coating properties, also the reducing the energy consumption for the process. In this regard, one of the important directions for improving these technologies with plasma is the development of their new versions, using the principle of adding inexpensive fuel-oxidizing mixtures based on hydrocarbons (natural gas, liquefied gas) with air. This type of plasma-fuel type of spraying will be promising for application at the present time, first of all, in order to obtain refractory functional coatings. For this purpose, the opportunity for upgrading an industrial unit/system for plasma spraying of powder materials with arc plasma torch of 25–40 kW power was investigated with the use of experimental variant of a fuel gas-vortex intensifier. Herewith the thermal engineering assessment for possible parameters of the generated high-temperature flow from the torch with this intensifier was carried out to compare these with established thermodynamic characteristics on the applicability range of this system for optimization of the oxide and carbide coating spraying process (using the examples of Al2O3, Cr3C2 and other powders); and gas dynamic and heat transfer calculations of the intensifier operating regimes in this model unit was also performed. New regimes, which were analyzed in our research as the simulants of Al2O3 spraying, have the advantage over the N2-plasma regimes from the point of view of such kinetic parameter of powder processing as ability of heating factor of hot gas medium. Taking into account the calculated data, the experimental system was developed based on the standard spraying unit UPU-3D with a fuel intensifier of the selected design and the preliminary testing of its operation was carried out at the power of 30±2 kW under the following combination of gases in the torch: nitrogen and mixture of liquefied petroleum gas with air. This system has shown the stable operation in certain range of parameters and, according to the zonal calorimetrical measurement and photo-registration of jets, it provides 30–35 % more energy emission from torch generated jet (with attached fuel vortex chamber) in atmospheric conditions, in a comparison with the torch regime with pure N2-plasma with the same power on the arc of plasma heater. Use of the system creates an opportunity to spray carbide powders as well as oxide ones at improved intensity of coating producing in a comparison with standard regimes of commercial spraying units with N2 or Ar plasmas.

Authors: Martynov K. V. , Panteleeva L. A. , Blagodatskih I. A.
Published: April 2022

PURPOSE. Asynchronous motors are the main consumers of the electrical energy. Increasing their energy performance can contribute to a significant reduction in energy consumption in general. Using a combined 12-zone winding instead of the standard 6-zone one theoretically can lead to a decrease in electrical losses in the stator winding of the asynchronous motor and to reduce additional losses caused by the higher spatial harmonics. The main purpose of the work is to assess the effect of using a combined winding stator on the energy characteristics of the induction motor.

METHODS. The study was performed on two AIR71V4 electric motors, one of which had a standard winding and the other had a combined winding. In the experiment, the engines were rated voltage, and the load was carried out using an electromagnetic loading device. The engines were tested in the range of loads from idle to the nominal. The experiment was performed five times.

RESULTS. The work under analysis shows the dependences of the current strength, consumed active and reactive power, efficiency, and power factor from engine load.

CONCLUSION. The results of the study showed that an asynchronous motor with the combined winding over the entire investigated range of loads has a lower consumption of both active and reactive power, compared to a motor with a standard winding, while the power factors of these motors are practically the same. The greatest difference in efficiency was observed at loads lower than the nominal in favor of an improved engine model, but also at rated load, the motor with a combined winding has the higher efficiency of 3,1%.

Published: April 2022

THE PURPOSE. Investigation of the time structure forthedistortion source identification of the electric power quality and a method for its reduction using of a mobile software and hardware instrumentation system.

METHODS. The analysis of the number of complaints regarding low-quality electric power, the structure and values of the time spent on the identification of the distortion sources of the electric power quality indicators (PQI) for the standard values, taking into account all its components, was carried out.

RESULTS. It is determined that the number of complaints received by the power grid company regarding lowquality electric powerremains high. At the same time, it takes a long time to identify the distortionsource before putting in place the necessary remedial measures. According to the analyzed data, it can take up to 21 days. The number of cases when the distortion source of the PQI couldn’t be detected within two days was 117 cases of 419 analyzed. The solutions to reduce this time are proposed.

CONCLUSIONS. The solutions presented in the article make it possible to reduce the time spent on the source distortion identificationofthe PQI due to the use of a mobile hardware and software instrumentation system (HSIS). A variant of the HSIS structure is proposed, which includes sensors and the HSIS central unit. The proposed HSIS can be used in the absence of external communication channels through the use of data transmitted from the sensors of the system to the central unit using Long Range (LORA) or Wireless Fidelity (Wi-Fi) technologies. In addition, the HSIS provides time synchronization of all the sensors.

Published: April 2022

THE PURPOSE. Broadband passive filters (BBF) are an effective measure to mitigate harmonic resonance in power systems with nonlinear harmonic producing loads. The disadvantage of simple second-order broadband filters are pure selectivity and excessive fundamental frequency losses. This is especially evident in devices designed for low-order harmonics mitigation. This paper presents new broadband filter configurations with superior performances and low fundamental frequency losses.

METHODS. A general method of broadband passive filter design is considered. The filter has the form of single-loaded ladder LC-two-port. Conditions of minimal fundamental frequency loss of the filer are determined.

RESULTS. This paper presents new broadband filter configurations with superior damping performances and low fundamental frequency losses. Different broadband filter configurations are compared. The results show that 3-5 order broadband ladder filters have better filtering performance and lower power loss than traditional C-type filters.

CONCLUSION. The proposed broadband filters can be used for industrial power systems with powerful nonlinear loads. This will normalize the power quality and at the same time improve the energy efficiency of compensating devices.

Teaching multimodal metadiscourse in academic English as a foreign language
Authors: Carrió Pastor María Luisa
Published: April 2022

Even though both visual and textual elements create multimodal discourse, the former have received less attention (Kumpf, 2000) than the latter (Hyland, 2005) when teaching a foreign language. The hypothesis of this study is that teaching how multimodal metadiscourse is organized in academic writing may be beneficial if implemented in English for specific purposes. The objectives of this analysis are to identify the patterns of multimodal metadiscourse and to study if teaching the categories of multimodal metadiscourse could improve performance at communicating effectively in an increasingly multimodal world. Thus, a corpus of sixty-four academic papers on engineering written by native English speakers was compiled. Then, the visual and textual metadiscourse elements were classified with a tool and manually to identify patterns that could be used for teaching multimodal metadiscourse. Additionally, the frequencies of the textual and visual elements were identified. Tasks based on the results were proposed and carried out with an experimental group at Universitat Politècnica de València. The results show the patterns of multimodal metadiscourse, the classifications and the outcomes of the experiment with the students. Finally, conclusions shown that multimodal literacy is not implicit or associated to language proficiency, it should be instructed.

Pleonasme dalam bahasa Indonesia dapat dipandang sebagai gaya bahasa. Namun di sisi lain, pleonasme menjadi faktor ketidak efektian kalimat. Pleonasme adalah salah satu gaya bahasa yang kerapkali digunakan dalam bahasa Indonesia. Pleonasme merupakan pemakaian kata yang mubazir (berlebihan). Jika ditinjau dari hakikatnya sebagai gaya bahasa, keberadaan pleonasme dapat dipandang sebagai sebuah kewajaran. Pleonasme sering digunakan oleh penutur untuk mempertegas sebuah pikiran atau memperkuat sifat ekpresif kalimat. Kalimat sebagai sarana penyampaian pesan dalam komunikasi tentunya harus memuat informasi secara lengkap, akurat, dan tidak bertele-tele. Kehematan adalah salah satu ciri yang perlu diperhatikan dalam membentuk kalimat efektif. Dengan demikian, hal ini tentunya berbenturan dengan hakikat pleonasme. Pleonasme secara jelas menunjukkan penggunaan kata-kata secara berlebihan dari yang dibutuhkan. Dilihat dari sudut pandang keefektifan penggunaan unsur bahasa dan kalimat efektif, pleonasme tidak dapat diterima keberadaanya.

Introduction. The scientists all over the world studied the problem of death in the workplace for two decades. Sudden cardiac death occupies a leading place in the structure of workplace death from a common disease (83-90% of cases). The urgency of this problem dictates the need for research to study the main factors and causes of death in the workplace from a common disease, followed by the development of a comprehensive program to prevent them. The study aims to learn the circumstances and causes of sudden death in the workplace due to a common disease and substantiate the program for its prevention. Materials and methods. The researchers conducted an analysis of investigation materials of fatal accidents in the workplace for 2018-2020 at enterprises and organizations of the Republic of Bashkortostan, recognized during the investigation as unrelated to production and occurred as a result of a common disease. We studied in detail the specific circumstances and causes of death. Scientists analyzed the number of deaths in the workplace from common diseases both in absolute and relative units (per 1000 employees), in the context of economic activities, taking into account the organizational and legal forms of enterprises and organizations. Results. 165 employees died from common diseases in the workplace during the analyzed period. We observed the greatest proportion of workplace deaths from a common disease at enterprises and organizations of the following types of economic activity: manufacturing - 22.9%, transportation and storage - 17.4%, provision of electric energy, gas and steam, water supply, sanitation - 10.3%. The main causes of sudden death in the workplace from common diseases, according to the forensic examination, were diseases of the circulatory system (97.1%), which were more often registered in men (97.4%) aged 56-60 years. Conclusion: The lack of complete and reliable information about the causes and risk factors of death in the workplace from common diseases in various sectors of the economy, as well as the need to develop a prevention program to minimize the likelihood of its development, served as the basis for this study.
A FEMINIST CRITICAL DISCOURSE ANALYSIS OF QUANTITATIVE APPROACHES IN THE MIXED METHODS BASELINE STUDY OF SUSTAINABLE DEVELOPMENT GOAL 5 IN KENYA
Authors: Mulama Anne Stella
Published: April 2022

Feminist scholars have in the past upheld qualitative research methods and rejected or argued for the modification of quantitative research methods, but mixed methods are steadily becoming popular. While developing Sustainable Development Goal 5 baseline indicators, this study uses feminist critical discourse analysis to revisit claims against quantitative approaches from the 2014 Kenya Demographic and Health Survey (KDHS). The integrated results from the mixed methods convergent design study show that the approach usefully triangulates the findings. The 2014 KDHS, though suitable for showing trends and prevalence rates, has instances of gender related bias, excludes minorities, and invisibles violent acts against women and girls related to public unrest. This article contributes to the promotion of mixed methods for feminist research.

This study uses as secondary sources the 2014 Kenya Demographic and Health Survey report and data which are available on www.dhsprogram.com.

Published: April 2022

Contexto e Objetivo: A relevância de uma investigação empírica no setor da saúde e em meio hospitalar surge do facto de estes serem contextos emergentes e complexos, onde a problemática do comportamento organizacional e, em particular da satisfação profissional, tem sido alvo de atenção por parte dos gestores. Torna-se assim premente a pluralidade de saberes e cooperação multidisciplinar de áreas científicas para uma melhor compreensão da importância da gestão da satisfação nas organizações de saúde. Apesar dos inúmeros fatores considerados críticos para o sucesso da gestão da satisfação, cingiu-se o estudo à cultura organizacional, procurando-se analisar o perfil e a sua relação com a gestão da satisfação dos trabalhadores de três serviços que integram um departamento de um hospital público de saúde. Método: O estudo, de natureza quantitativa e de corte transversal, assentou num fenómeno singular de características únicas — o Departamento de Ginecologia/Obstetrícia e Reprodução Humana de uma Unidade Hospitalar —, recorrendo ao Organizational Culture Assessment Instrument (OCAI), traduzido e adaptado para a língua portuguesa. O OCAI foi aplicado a 136 trabalhadores com cargos e funções profissionais distintas dos três serviços do departamento. O instrumento utilizado foi validado, apresentando boas qualidades psicométricas. Resultados: A perceção dos trabalhadores sobre os diferentes serviços do departamento evidenciou congruências em relação à cultura organizacional, reconhecendo que nos serviços predominam características das culturas Clã e Hierárquica. No entanto, as discrepâncias entre a cultura atual (vigente) e a cultura futura preferida (ideal) indicaram que os trabalhadores, apesar de desejarem manter essas culturas em determinadas dimensões, idealizaram trabalhar num ambiente organizacional com características das quatro tipologias culturais. Conclusão: Determinadas características da cultura organizacional devem ser reajustadas, pois podem influenciar na gestão da satisfação dos trabalhadores constituindo um fator crítico de sucesso dos três serviços de saúde públicos.

Groundwater connections and sustainability in social-ecological systems
Authors: Huggins Xander , Gleeson Tom , Castilla-Rho Juan , Holley Cameron , Re Viviana , Famiglietti James S.
Published: April 2022

Groundwater resources are connected with social, economic, ecological, and Earth systems. We introduce the framing of groundwater-connected systems to better represent the nature and complexity of these connections in data collection, scientific investigations, governance and management approaches, and groundwater education. Groundwater-connected systems are social, economic, ecological, or Earth systems that interact with groundwater, such as irrigated agriculture, groundwater-dependent ecosystems, and cultural relationships to groundwater expressions such as springs and rivers. Groundwater-connected systems form social-ecological systems with complex behaviours such as feedbacks, non-linear processes, multiple stable system states, and path dependency. These complex behaviours are only visible through this integrated system framing and are not endogenous properties of physical groundwater systems. The framing is syncretic as it aims to provide a common conceptual foundation for the growing disciplines of socio-hydrogeology, eco-hydrogeology, groundwater governance, and hydro-social groundwater analysis. The framing also facilitates greater alignment between the groundwater sustainability discourse and emerging sustainability concepts and principles. Aligning with these concepts and principles presents groundwater sustainability as more than a physical state to be reached that additionally must integrate place-based and multi-faceted goals, values, justice, knowledge systems, governance and management to maintain groundwater’s social, ecological, and Earth system functions. The groundwater-connected system framing can underpin a broad, methodologically pluralistic, and community-driven new wave of data collection and analysis, research, governance, management, and education. These developments, together, can invigorate efforts to foster sustainable groundwater futures in the complex systems groundwater is embedded within.
Unbiased misinformation policies sanction conservatives more than liberals

Published: April 2022

In response to intense pressure from policy makers and the public, technology companies have enacted a range of policies aimed at reducing the spread of misinformation online1-3. The enforcement of these policies has, however, led to technology companies being regularly accused of political bias4-6. We argue that even under politically neutral anti-misinformation policies, such political asymmetries in enforcement should be expected, as there is a political asymmetry in the sharing of misinformation7-12. We support this argument with an analysis of Twitter data from 9,000 politically active users during the U.S. 2020 presidential election. While users on the political right were indeed substantially more likely to be suspended than those on the left, users on the right also shared far more links to low quality news sites – even when news quality was determined by politically-balanced groups of laypeople, or groups of only Republicans – and were estimated to have a far higher likelihood of being bots. We find similar associations between conservatism and low quality news sharing (based on both expert and politically-balanced layperson ratings) in seven other datasets of sharing from Twitter, Facebook, and survey experiments, spanning 2016 to 2023. These results demonstrate that political imbalance in enforcement need not imply bias, and should not dissuade technology companies from taking action against the spread of misinformation.
Neural correlates of verbal fluency revealed by longitudinal T1, T2 and FLAIR imaging in stroke
Authors: Xiong Yanyu , Khlif Mohamed Salah , Egorova-Brumley Natalia , Brodtmann Amy , Stark Brielle C
Published: April 2022

Diffusion-weighted imaging has produced useful biomarkers of verbal fluency post-stroke but acquiring diffusion data is not always clinically feasible. Further, it has been demonstrated that subcortical regions may contribute to verbal fluency, though the predominant focus in the literature has been on cortical contributions to verbal fluency. Finally, the majority of recovery-oriented research on language in stroke has been cross-sectional, which does not allow for actual modelling of language change over time. Focusing on the contribution of subcortical and white matter structures to language recovery of individuals with ischaemic stroke, our present study, therefore, used the information of white matter disconnection and volumetric measurements obtained directly from non-diffusion-weighted anatomical images (T1, T2 and FLAIR), which are routinely acquired in clinical settings, to understand verbal fluency performance over time. We derived neuropsychological and anatomical neuroimaging data of individuals at 3- and 12-months post-stroke from the Cognition And Neocortical Volume After Stroke study, a longitudinal study of ischaemic stroke survivors and healthy stroke-free individuals. Cortical volumetric and thickness measurements were derived from FreeSurfer. White matter disconnection was quantified by two metrics based on BCBToolkit: Disconnection severity – the proportion of lesioned voxel volume to the total volume of a tract, and disconnection probability – the probability of the overlap between a subject’s lesion and a tract. Using the linear mixed multiple regression method based on 5-fold cross-validation, we correlated the semantic and phonemic fluency scores of participants with longitudinal measurements of subcortical grey matter volume and 22 literature-driven bilateral white matter tracts of interests, while controlling for demographic variables (age, sex, handedness and education), total brain volume, lesion volume, and cortical thickness at both time points.Our results showed that the right subcortical grey matter volume was positively associated with phonemic fluency (p < 0.05) from 3 months to 12 months post-stroke and the model predictions improved with cross-validation. The disconnection probability of the left superior longitudinal fasciculus II and the left posterior arcuate fasciculus was negatively correlated to semantic fluency (p < 0.05) from 3 months to 12 months post-stroke, but this model did not generalize well following cross-validation.We conclude that subcortical grey matter volume is strongly related to phonemic fluency recovery after stroke, and that the association of white matter disruptions with semantic fluency recovery are strongly influenced by the specific lesion features of the stroke patients within the present study.
Phonological Networks and Systematicity in Early Lexical Acquisition
Authors: Laing Catherine
Published: April 2022

Infants' early words tend to be phonologically similar. This may reflect a systematic approach to early production, as they adapt newly-acquired forms to fit familiar structures in the output. This 'rich-get-richer' approach to phonological acquisition, known as preferential attachment in network science, assume that new words cluster together with existing phonologically-similar words in the lexicon (or network). This contrasts with recent work (e.g. Fourtassi et al., 2020) showing that the learning environment is the key predictor in learning (i.e. preferential acquisition). However, previous network analyses draw on vocabulary norms, which do not capture individual variability in word learning; here, phonetic transcriptions of nine infants' word productions were analysed from word onset to age 2;6. Network growth models were generated to test whether acquisition was best modelled through preferential attachment or preferential acquisition. Results show that preferential attachment is more convincing, suggesting that infants' early words are systematically acquired according to their phonological properties, such that newly-acquired words are phonologically similar to existing words in the network. Furthermore, infants produce their early words more systematically than we would expect from looking at target forms alone.
Success in life after service: A perspective on conceptualizing the well-being of military Veterans

LAY SUMMARY

Military members want to do well when they leave service. Good well-being is one way of thinking about success in the transition to life after service. The word well-being has different meanings to different people, which can be confusing. To help Veterans, it must be clearly defined. Some see well-being as something inside a person; others see it as how people are doing in the outside world. People can have poorer or better well-being in many areas of life, not just in how they feel. This article describes a way of thinking about well-being that can work for different purposes.

Published: April 2022

The drying characteristics of the pine woods were examined in the vacuum drying system under different operating conditions. Three drying temperatures (40, 50 and 60 ◦C), three operating pressures (0.6, 0.7 and 0.8 bar) and three times of exposure to vacuum (5, 10 and 15 minutes) were investigated. Experiments were carried out to obtain data from the sample moisture content. In this study, the application of Artificial Neural Network (ANN) to estimate pine woods' moisture content (output parameters for ANN modeling) was examined. Drying time, drying temperature, relative humidity, pressure and air temperature were accepted as the input parameters of the model. Training and validation were performed with great accuracy. The moisture content of woods is formulated by the ANN method. The proposed method offers more flexibility; therefore, the determination of the moisture content in pine woods is quite simpler.
Molluscs of the genus Onoba H. Adams, 1852 from the Barents Sea and adjacent waters (Gastropoda: Rissoidae)
Authors: Nekhaev I.O. , Deart Yu.V. , Lubin P.A.
Published: April 2022

Four species of Onoba H. Adams et A. Adams, 1852 are reported from the Barents Sea and adjacent waters of Arctic Basin and White Sea: O. aculeus (Gould, 1841), O. semicostata (Montagu, 1803), O. leptalea (Verrill, 1884) and O. improcera Waren, 1996. Onoba karica Golikov, 1986 is considered as a synonym of O. leptalea. Both O. mighelsi (Stimpson, 1851) and Alvania jeffreysi (Waller, 1864) were erroneously recorded from the Russian waters by previous authors.
Concept of hybridogeneous speciation of vertebrate animals: complex studies of unisexual species of Reptilia
Authors: Kupriyanova L.A.
Published: April 2022

Results of study of unisexual-bisexual complexes from different lizard families have been generalized, using cytogenetic, molecular-cytogenetic data in combination with allozyme, mt-DNA and microsatellite-DNA analysis. These extensive studies of parthenogenetic species of reptiles confirm the concept hypothesis of hybridogeneous speciation of vertebrate animals based on an inter-specific hybridization with forming of a new hybrid unisexual species, clones and forms. Modern researches are considerably extended understanding of evolutionary interrelated phenomena such as hybridization-unisexuality-polyploidy-and ‘balance’ genome. The hybridization may be phylogenetically constrained. An implication of hybridization might be in genome destabilization, and therefore in its rapid diversity, arising of new gene’s variants, of new specific allozyme alleles and microsatellite loci, lacking in parent’s genomes. The implication of unisexuality (in case of its rises) is the maintainance of parental gene block along fixation of new variant of the latter resulting from hybridization.
Karyotype of the Eichwald’s Toad, Bufo eichwaldi (Amphibia: Bufonidae)
Authors: Skorinov D.V. , Berezina Y.A. , Kidov A.A. , Matushkina K.A. , Pasynkova R.A. , Litvinchuk S.N.
Published: April 2022

For the first time the karyotype of Bufo eichwaldi was described (2n = 22). It consists of 12 large metacentric (V), 8 small metacentric (v), and 2 small submetacentric chromosomes (sv): 12 V + 8 v + 2 sv, NF = 44. According to the number of chromosomes and arrangement of NORs (in the end of long arms of pairs 6), the karyotype of B. eichwaldi has no differences from karyotypes of close related B. bufo and B. verrucosissimus. The main difference is wide heterochromatin C-blocks in long arms of pair 10, which is present in B. eichwaldi and lacking in B. bufo and B. verrucosissimus. Moreover, in the Eichwald’s toad the pair 1 has, as a rule, larger size if compare with other two species. Additionally, these two species had two submetacentric chromosomes (pairs 4 and 7), but B. eichwaldi had only one (pair 7).

The paper analyzes current problems and potential opportunities for the formation and implementation of communication strategies by Ukrainian enterprises in European economic integration. It is customary to develop a communication strategy following the critical objectives of the company to promote close and effective communication between the company and stakeholders. The key stages of the development of communication strategies of enterprises are analyzed. The critical socio-economic elements of communication systems of enterprises are characterized. The comparative characteristic of electronic and traditional (verbal/printed) communication types of enterprises under European integration conditions is formed. The interpretation and understanding of the management of the majority of Ukrainian enterprises of the concept of integrated communications is studied. Several factors (factors) that are significant obstacles to applying the concept of integrated communications have been identified. The importance of traditional communication tools of the enterprise is analyzed. It is established that they are not able to cover absolutely all contact audiences fully, stakeholders to ensure a high level of efficiency in the implementation of communication strategies of the enterprise. It is substantiated that the constant scientific and technical development of technologies encourages the use of the latest communication tools, creative approaches, and creativity. Innovative communication tools are systematized. It is established that analysis, monitoring, research of application of information, communication technologies in the management system of Ukrainian enterprises will increase the level of objectivity of assessment, establish a measure of realizing the potential of info-communication management of enterprise personnel to achieve the main goals of the enterprise.

Authors: Nikiforovа Liliia
Published: April 2022

The article considers the use of modern innovative information technology (IT) in general in the digital economy and in e-commerce, as its most sensitive part. First of all, the paper shows that since the beginning of the XXI century one of the main trends in the economy and society in general is the penetration of innovative information technologies in various fields of human activity, which entails global digitalization of both economy and society as a whole. E-commerce, as part of the digital economy, has been shown to be a driving force in accelerating global economic development and creating new markets. E-commerce also opens up new opportunities for inclusive and sustainable innovation growth. It is argued that the rapid development of e-commerce became possible only after the percentage of global Internet penetration exceeded some critical level, which led to its availability to the general public. In turn, the emergence of more and more new users on the Internet, the widespread use of various social networks and the rapid growth of internet of things (IoT) has led to the data explosion and the emergence and spread of technology such as Big Data. The main advantages of using Big Data in modern analytics in comparison with traditional methods are considered in the work. The place and role of Big Data technologies and tools in the digitalization of the Ukrainian economy are analyzed. It is proved that the intensive development and spread of the use of Big Data in all spheres of modern society leads to the active use of innovative IT. Based on the analysis, the main areas of use of Big Data are identified, namely: credit scoring, segmented or personalized services, risk management, anti-fraud system and using blockchain technology. The use of these technologies, in turn, will minimize customer effort and increase the efficiency of B2B and B2C models in both the digital economy and e-commerce.
