The matrix algorithm for calculation of single-dimension wave through multi-layer structure is proposed. The case of simultaneous incidence on structure two waves in opposite directions is investigated. The structure is presented as successive uniform layers having different parameters. In the basis of method is established the analogy between propagation of wave in multi-layer wave-conducting structure and chain which consist of successive connected four-pole blocks of propagation and connection. The results received on the model of four-pole blocks are generalized to the case of propagation of one-dimension waves in multi-layer structure. It is found the resulting matrix which is formatted by successive product of propagation and connection matrix for structure in a whole. On the basis of calculation scheme receiving elements of last matrix from the elements of previous matrix is proposed the algorithm which allows by recurrent way to find the resulting matrix for arbitrary number of medium. On the basis of proposed algorithm, the amplitudes of leaving out structure waves through the amplitude of coming waves may be calculated. Also, the coefficients of reflection and passing by energy for the structure as a whole may be calculated. For the convenience of machine programming, it is proposed the block-scheme of program which realizes the algorithm. This program includes the under-program which calculates the elements of last matrix from the elements of previous matrix. The proposed the recurrent formulas which allows to generalize proposed algorithm to the propagation of electromagnetic waves. It is proposed the recommendations which allow to generalize proposed algorithm to the waves which do not have the harmonic character.

Authors:   Necmettin Erbakan University, Turkey, Ekizer Feyza Nur
Published: August 2022

It is a fact that personal features and qualities play a crucial role in determining learners' success or failure in their attempt to learn foreign languages. It was these factors that lit a bulb in the mind and opened a path to set off to find out how these features affected the learners’ communication eagerness in L2. The main aim of the current study is to explore the relevance between the learners’ horoscopes and their willingness to communicate utilizing a mixed-method research design. Willingness to communicate (WTC) and Self-perceived communicative competence (SPCC) surveys have been conducted for the quantitative section and a semi-structured interview with an in-depth content analysis for the qualitative part. Interestingly, no significant affect of horoscopes on students’ willingness to communicate was found out, however, the interviews elaborated to some extent that among the 5 other stated horoscopes, Leos were more willing to communicate with their friends, with their classmates and with strangers.

Published: August 2022

An emerging trend in modern medical laboratories is automation, and it is having a positive impact on the quality of service to patients and on the safety of medical laboratory staff. The use of automation in medical laboratories enable many tests by analytical instruments with minimal use of an analyst. These automated instruments result in increasing the capabilities of a laboratory to process more workload with minimum involvement of manpower. Total Laboratory Automation (TLA) has many advantages including workload reduction, less time spent per sample, increased number of tests done in less time, use of a smaller sample amount, decreased risks for human errors, and higher reproducibility and accuracy. With the future practice of medical technologists in a technologically advanced future in peril. What edge do medical technologists have over Artificial Intelligence and Robotics that would still make them essential in medical laboratories in a future that is technologically advanced?

Published: August 2022

As a result of mixed marriages, children born based on their parents' descendants (the principle of ius sanguinis), or the nationality obtained based on where a child is born (the principle of ius soli) depends on the principle adopted by each country, giving implications for the existence of children who have dual nationality. This also creates the problem of a limited citizenship age limit for choosing citizenship, causing problems with a child's citizenship status, because the regulations regarding the age limit for children to choose citizenship also differ from one country to another. The research method used is normative juridical. The results showed that to answer to the needs of society, especially for children who have dual citizenship, the ideal age to choose citizenship should be limit to 25 years so that the person concerned has completed his education in higher education so that changes need to be made to the Citizenship Law, especially the article regarding the age limit for dual citizenship.

Authors: Sharaskina O.
Published: August 2022

Purpose:to study the influence of the Bezernary diet on the parameters of growth and development of foalsfrom leaving to 1.5 years.

Materials and methods.The object of the study was the young of the Oryol trotter. After leaning, two groups of 5 goals were formed in each. The concentrate part of the diet of the foals from the control group consisted of compound feeds based on micronized grain and balancing feed additive. The experimental group as concentrated food received granular beze -free compound feed and balancing feed additive. The beginning of the experience corresponded to the time of leaving the foals, when they reached the age of 6 months. Control points of accounting of growth and development indicators, as well as biochemical blood test - after 3 (I), 6 (II) and 9 (III) months after the start of the accounting period. Blood was taken from the jugular vein in front of the morning feeding. The concentration was determined: common protein, albumin, globulin, urea, alkaline phosphatase, amylase, glucose, cholesterol, calcium, phosphorus, magnesium, potassium, sodium, chlorides, iron, triglycerides, lipases. To control the growth parameters, they measured: the height at the withers, the slanting of the body, the gaping of the chest behind the shoulder blades, the girth of the heel, the width of the chest in the shoulder-lobe joints, the width in macloki. The indicators of absolute and relative growth in terms of measures for each accounting period were calculated.

Results.According to the results of the 1st period, in the animals of the experimental group in comparison with the control, a reliable increase in the concentration of magnesium was revealed. At the end of the II period in the experimental group, the indicators of magnesium and albumins were significantly higher, and cholesterol and gamma-globulin are lower than in the control group at the end of the 3rd period in the control group the levels of cholesterol, iron and thyroxine were significantly higher. At the same time, in the experimental group, the concentration of cholesterol was lower than the boundary of the reference value for adult animals. In the same period, reliable differences were recorded by indicators of absolute and relative growth, which in animals of the control group turned out to be significantly higher. In the same group, the indicators of the measure of the oblique length of the body and the width of the chest in the shoulder-lobe joints were reliably lower.
Intrapartum Ultrasound in Maternal Lateral Position. A Prospective Observational Study
Authors: Cuerva Marcos Javier , Rodriguez Elena , Lopez Francisco , Bartha José Luis
Published: August 2022

Background: Intrapartum ultrasound (ITU) techniques have been described only in maternal semi-recumbent position. However, other birthing positions, such as side-lying, are more comfortable for many mothers. The present study aimed to test the hypothesis that ITU measurements can be obtained in maternal lateral positions during the second stage of labor. Methods: A single-center, prospective observational study was conducted. Women who preferred a side-lying position during the second stage of labor participated in the study. The women were asked to grasp their upper knee and flex it to perform the ultrasound scan. The transducer was first placed in the frontal plane and then rotated to the midsagittal plane (the probe was placed at the level of the fourchette). Results: 34 women participated in the study. Position of the fetal head, angle of progression, and head-perineum distance with and without contraction were obtained in all women. There was a moderate correlation between the head-perineum distance with contraction and the ITU to birth time (r = 0.466; p = 0.009). Conclusions: ITU in maternal lateral position (side-lying) is a simple technique that avoids unnecessary changing of position during the second stage of labor.
LATE PALEOZOIC REMAGNETISATION AS AN INDEPENDENT INDICATOR OF TECTONIC PROCESSES IN THE SOUTHERN URALS
Authors: Golovanova Inessa Vladimirovna , Danukalov Konstantin Nikolaevich , Sal’manova Raushaniya Yurisovna
Published: August 2022

Analysis of secondary magnetization components (Late Paleozoic remagnetization) makes it possible to trace the formation of the Southern Urals folded system. The paper presents new data on the Late Paleozoic remagnetization of rocks in the Southern Urals. The results of the paleomagnetic study of rocks in various structural zones of the Southern Urals, obtained since 2009, were revised and supplemented again to identify the remagnetization component. Combined analysis of the newly obtained results and previously published data on Late Paleozoic remagnetization shows that in the western segment of the western slope of the South Urals the intermediate-temperature magnetization component (ITC) was acquired prior to or at the initial stages of deformation. In contrast, the ITC observed in the eastern segment arose after folding. In the western part of the Magnitogorsk zone in Devonian-age rocks, the average for all sites is post-folding. Deformations here occurred long before the final stage of the development of the Urals, most likely in late Devonian — early Carboniferous. In the Magnitogorsk-Bogdanovsky graben, in the early Carboniferous rocks, ITC has arisen during the process of deformation or shortly before it and at its initial stages. The Late Paleozoic remagnetisation identified in the paleomagnetic records is regional in nature and probably reflects a collisional event of the final stage of the evolution of the Ural Paleocean. Collision processes which occurred in the Southern Urals from the Late Devonian until the Late Permian time had undoubtedly left their trace in the western structures (in present-day coordinates). Within the passive margin of Baltica the collision resulted in the formation of a lateral series of fold-and-thrust structures. They started from the Main Uralian Fault westward, with possible gradual termination of this process towards the Pre-Uralian Foredeep. Paleomagnetic results of this research work support these assumptions.

The up-to-date assessment of the open data of participants in the turnover of precious metals, preciousstones and products made of them, given in this article, allowed to justify the need for integration of info rmation systems. The state is called upon, in order to ensure the interests of its citizens, to support the established trend, the current direction of development. A sufficiently large number of risks that hinder the implementation of the state integrated information system in the sphere of control over the turnover of precious metals, precious stones and products made of them at all stages of this turnover (hereinafter referred to as the DMDK GIS) are balanced by theoretical justification and practical application. The scientific and methodological provisions of economic theory are presented, revealing the necessity, tasks and directions of accounting for strategic state resources. The conclusion is made about the need for prompt response to the problems and failures of the already built accounting model on the DMDK GIS platform. Using the example of the selected area, the concept of digitalization of accounting on a single platform for various participants is formulated, demonstrating the importance of regulating the parameters of innovative systems, including for the development of the economy as a whole.
Bounded Rationality of Decision-Making by Online Microfinance Organizations’ Consumers
Authors:   St. Petersburg University, St. Petersburg 199034, Russian Federation, Upravitelev Alexey A.
Published: August 2022

Microfinance is very popular in Russia, but this sphere is often associated with a number of socioeconomic problems, one of which is the population’s debt load. Often the clients of microfinance organizations (MFOs) are citizens from the poorest segments of the population who do not have a high level of financial literacy. The trend towards digitalization of the financial sector has a significant impact on the decision-making process of MFO services consumers. The subject of this paper is the problem of bounded rationality of decision-making, typical for users of online services of microfinance organizations. To reduce the negative effects on users of MFO services, the Central Bank reduces the maximum permissible interest rate for this type of organizations, and the Ministry of Finance organizes programs to improve financial literacy. The aim of the study is to estimate the efficiency of existing methods for solving this problem and to propose our own solution based on the concepts of behavioral imperialism. The relevance is that the digitalization of the financial sector is rapidly increasing, since both classic services are moving online and completely new technological financial services (fintech) appear, which requires the user to master new skills of working in the online environment. In conclusion, the author gives his recommendations for financial literacy programs that can reduce the bounded rationality of financial decision-making.

The article presents an overview of theoretical approaches to the study of the content and channels of financial contagion, the main methods and models of its quantitative analysis. The results of contemporary domestic and foreign studies devoted to the assessment of the intensity, direction and scale of contagion across countries and industries are discussed. We conclude that Russian researchers pay insufficient attention to this problem. In the practical part of the article, we test hypotheses about the transmission of contagion from the oil market to a number of Russian large companies belonging to different sectors of the economy. Sanctions and pandemic shocks are seen as external triggers for contagion. We use a large amount of oil and stock price data for a period that includes the 2014–2016 monetary and financial crisis and the 2020 pandemic crisis. To distinguish between periods of high and low market volatility, which is necessary to detect contagion, we calculate moving coefficients of variation for oil and stock prices. To identify cases of contagion, we employ the Forbes-Rigobon test, tests for coasymmetry and cocurtosis of distribution. The resulting estimates confirm numerous cases of contagion, with their number increasing as higher distribution moments are analysed. In addition, we conclude that during the 2014–2016 crisis, the Russian oil and gas industry showed the greatest vulnerability to contagion from the oil market. However, the pandemic shock changed the telecommunications sector turned out to be the most susceptible to contagion from the oil market in Russia. The banking sector in both crises showed a high degree of contagion from the oil market. At the same time, companies associated with ferrous and non-ferrous metallurgy, mining and processing of precious metals, as well as the chemical industry demonstrated the greatest resistance to financial contagion.
COVID-19 Pandemic as a Factor of Public Debt Increase. The Case of Kazakhstan in the Global Context
Authors:   Kazakhstan Institute of Strategic Studies under the President of the Republic of Kazakhstan, Nur-Sultan 010000, Republic of Kazakhstan, Dodonov Vyacheslav Yu.
Published: August 2022

One of the main effects of the COVID-19 pandemic is a significant aggravation of the debt burden in most countries of the world, due to increased costs to support the economies. In Kazakhstan, similar problems also caused a significant increase in the volume of public debt and expenses for its servicing, while due to the specifics of the country’s economic model, the channels of influence of the pandemic on the debt sector were more numerous because of the impact of external shocks. The growth of government debt and the debt servicing cost during the pandemic years was affected by such factors as the growth of budget’s expenditures to support the economy; a drop in revenues due to lower oil prices; the devaluation of the tenge and growth of the cost of servicing external debt; increase of interest rates in the domestic debt market. A comparison of the parameters of public debt increase and loss of economic growth based on the ratio of these two indicators is proposed as a generalized indicator of the effectiveness of debt buildup during the pandemic. This approach showed that the debt increase in Kazakhstan was quite effective. Nevertheless, the effects of the fight against the pandemic had a serious negative impact on Kazakhstan’s public finance system, and in the debt sphere the main problem now is the escalation of debt servicing costs, which will be a significant burden on the budget process, at least for the next few years.

Correlation between Degree Modifiers and their Effect on Meaning: Iraqi EFL learners' Perception
Authors: Wafa'a Hussain Jabur Al-Temeemey
Published: August 2022

Abstract

                                                                                      

       The semantics of degree modification and its effect on mutating the meaning of structures they appear in have held considerable appeal for specialists in areas ranging from lexical semantics to language pedagogy. Although the general concept of degree modifiers received a lot of attention in the twentieth century studies in linguistics, it has been treated only theoretically. The pedagogical  side  of degree modifiers seems to be a neglected topic. This paper is an attempt at addressing this gap in the literature. The  main  aim of this research is to examine students' knowledge in  the functions of the degree modifiers and their semantic effect. The paper investigates whether the effect of degree modifiers on meaning is distinguished  to the same extent by fourth year students majoring in English. To this end, the researcher designed a multiple choice question test to determine whether students are able to find the correlation between the type of degree modifier used and the meaning of the given sentences. Data analysis was performed using a number of descriptive measures in addition to  a T-test and   a Chi-square test. The results show that the Iraqi English major students face severe difficulty in distinguishing differences in meaning resulting from using degree modifiers in different contexts. The results also show a gradation in difficulty across the different types of modifiers.

Do anticipated consequences of climate change affect risk preferences and cooperation? – An experimental study with farmers, students, and representatives of the general population of Germany
Authors: Gruener Sven , Mußhoff Oliver
Published: August 2022

Human-made climate change is one of the most pressing challenges of the 21st century. This paper examines how thinking about future consequences of climate change influences decision-making. Using controlled information intervention experiments, we address ambiguity preferences, risk preferences, and willingness to cooperate among farmers, students, and representatives of the general population of Germany. The results show that after being reminded of climate change, farmers increase their investments in uncertain assets. There are also common patterns across the subject pools: willingness to cooperate seems to be nearly unaffected by reminding subjects of future consequences of climate change.

Continuous action with a neurobiologically inspired computational approach reveals the dynamics of selection history
Authors: Makwana Mukesh , Zhang Fan , Heinke Dietmar , Song Joo-Hyun
Published: August 2022

Everyday perception-action interaction often requires selection of a single goal from multiple possibilities. According to a recent framework of attentional control, object selection is guided not only by the well-established factors of perceptual salience and current goals but also by selection history. Yet, underlying mechanisms linking selection history and visually-guided actions are poorly understood. To examine such interplay and disentangle the impact of target and distractor history on action selection, we employed a priming-of-popout (PoP) paradigm combined with continuous tracking of reaching movements and computational modeling. Participants reached an odd-colored target among homogeneous distractors while we systematically manipulated the sequence of target and distractor colors from one trial to the next. We observed that current reach movements were significantly influenced by the interaction between attraction by the prior target feature and repulsion by the prior distractor feature. With principal component regression, we found that inhibition led by prior distractors influenced reach target selection earlier than facilitation led by the prior target. In parallel, our newly developed computational model validated that current reach target selection can be explained best by the mechanism postulating the preceded impact of previous distractors followed by a previous target. Such converging empirical and computational evidence suggests that the prior selection history triggers a dynamic interplay between target facilitation and distractor inhibition to guide goal-directed action successfully. This, in turn, highlights the necessity of an explicitly integrated approach to determine how visual attentional selection links with adaptive actions in a complex environment.

Models of consciousness need to explain both objective correlates of conscious experience as well as its subjective structure. However, such an explanation would not need to entail a reduction exclusively in terms of physical or neural systems. We briefly sketch a few points of contention with recent work on integrated information theory and some common assumptions made in the neuroscience of consciousness more generally.

Stereotyping others may be negatively related to one’s creativity, yet there is currently scant empirical evidence of a link between stereotyping and creativity; here, we explore this link in the marketing domain. In a field study, we introduced a novel intervention to disrupt marketeers’ dependency on stereotypes and boost creativity. The intervention decreased marketeers’ use of stereotypes when labeling consumer segmentation while enhancing the creativity of ideas. In a pair of online experiments, we asked participants to rate the stereotypicality and creativity of British advertisements and their purchase intention for the advertised product or service. We found a linear relationship between perceived stereotypicality and creativity. We also found a quadratic relationship between perceived stereotypicality and purchase intention, such that advertisements perceived as low and high stereotypicality induced higher purchase intention than the mediums. Finally, we discuss the psychological mechanisms that potentially link stereotyping and creativity and the implications for marketing.

Attention-Deficit / Hyperactivity Disorder (ADHD) is a debilitating condition affecting children and their families worldwide. Behavioral parent training is the only empirically supported non-pharmacological intervention for young children with mild to moderate ADHD. However, access to such treatment is limited in many countries. Here we identify the treatment needs of Brazilian families with children demonstrating symptoms of ADHD, and the barriers families face in accessing behavioral treatment. A qualitative needs assessment was undertaken with parents (n = 23), educators (n = 15), and healthcare providers (n = 16). Semi-structured telephone interviews were conducted, and common themes were identified through inductive coding of participants’ responses. Participants reported a lack of accessible behavioral treatment, together with delays in accessing treatment when available. The majority of parents had not received behavioral parent training, despite it being a recommended form of treatment. Parents, educators and healthcare strongly endorsed a need for practical tools to manage the behavior of children with ADHD. Existing services are not meeting the needs of children with ADHD and their families in Brazil. Easily accessed behavioral parent training programs are recommended to address the identified treatment gap for Brazilian children with ADHD and their families.
What makes background music distracting? Investigating the role of song lyrics using self-paced reading

Published: August 2022

It has been suggested that listening to music during reading may be distracting, but the empirical results have remained inconclusive. One limitation of previous studies is that they have often had limited control over the number of lyrics present in the songs. We report 4 experiments that investigated whether song lyrics make music distracting. Participants read short paragraphs in a self-paced reading paradigm in three sound conditions: 1) silence; 2) lyrical songs at ~150 words per minute; and 3) the instrumental version of the same songs. The results showed that listening to instrumental music either did not affect reading times or led to slightly faster reading times compared to silence. However, lyrical music led to an increase in reading times in three experiments. We conclude that instrumental music does not lead to distraction during reading. Song lyrics appear to be distracting, even if the observed distraction is quite mild.

Previous research has demonstrated that individuals with high levels of Intolerance of Uncertainty (IU) have difficulty updating threat associations to safety associations. Notably, prior research has focused on measuring IU-related differences in threat and safety learning using arousal-based measures such as skin conductance response. Here we assessed whether IU-related differences in threat and safety learning could be captured using eye-tracking metrics linked with gaze behaviours such as dwelling and scanning. Participants (N = 144) completed self-report questionnaires assessing levels of IU and trait anxiety. Eye movements were then recorded during each conditioning phase: acquisition, extinction learning, and extinction retention. Fixation count and fixation duration served as indices of conditioned responding. Patterns of threat and safety learning typically reported for physiology and self-report were observed for the fixation count and fixation duration metrics during acquisition and to some extent in extinction learning, but not for extinction retention. There was little evidence for specific associations between IU and disrupted safety learning (e.g., greater differential responses to the threat vs. safe cues during extinction learning and retention). While there was tentative evidence that IU was associated with shorter fixation durations (e.g., scanning) to threat vs. safe cues during extinction retention, this effect did not remain after controlling for trait anxiety. IU and trait anxiety similarly predicted greater fixation count and shorter fixation durations overall during extinction learning, and greater fixation count overall during extinction retention. IU further predicted shorter fixation durations overall during extinction retention. However, the only IU-based effect that remained significant after controlling for trait anxiety was that of fixation duration overall during threat extinction learning. Our results inform models of anxiety, particularly in relation to how individual differences modulate gaze behaviour during threat conditioning.

The objective of this study was to investigate the nutritional composition and the optimal conditions of ultrasonic extraction of total saponin triterpenoid (TST) and total phenolic content (TPC) from Ganoderma atrum using response surface methodology (RSM). An optimal model according to the Box - Behnken design has been formulated to extract TST Y1 and TPC Y2 with three factors: extraction temperature (X1), ultrasonic time (X2), and ultrasonic power (X3). Following this model, the optimal parameters for the extraction process to obtain the highest content of TST and TPC were extraction temperature of 65oC, time of 83 mins and ultrasonic power of 310 W. The experimental values of TST and TPC were 1.08±0.04% and 122.52±0.15 mg GAE/g, respectively.

The M4.7 earthquake that occurred at the end of 2012 confirmed the danger of triggered earthquakes in the Song Tranh 2 hydropower region, where earthquakes have not ever been recorded before the impoundment in 2010. The task of assessing the triggered earthquake hazard and forecasting its impact on the hydroelectric dam is extremely urgent. To improve the accuracy of this impact assessment, it is necessary to access the active faults for triggered earthquakes to be more effective in earthquake seismic hazard assessment. In this paper, the authors presented a combination of analytical methods combining geological - geophysical data in identifying active sources of triggered earthquakes that stimulate Song Tranh 2 hydropower reservoir with a 3-step analysis process. Research results have identified 5 sources of earthquakes related to 4 active faults connected with the Song Tranh 2 hydropower reservoir.

Four plant species in Con Dao shared together a Vietnamese name as “cay Nua”. They have habits, tubers and leaves quite similar each other. However, they belong to 2 families, which have caused a lot of confusions in exploitation, cultivation and use in the life. Among of them, 2 species belong to the genus Tacca (Taccaceae) as T. leontopetaloides and T. palmate, 2 remained species belong to the genus Amorphophallus as A. macrophyllus and A. coudercii. The species T. leontopetaloides is cultivated for tubers making starch and T. palmate is collected in the wild for medicine. While the tubers of A. macrophyllus and A. coudercii are not as edible tubers. For avoiding confusion in exploitation and using, the article described 4 above species and supported new morphological characters and new distribution of 2 Amorphophallus in Con Dao island.

This research presents the synthesis process of Wollastonite mineral by two stage reaction, hydrothermal and calcination, using Vietnam rice husk and portlandite. The rice husk ash after burning was batch mixed with Ca(OH)2 with the Ca/Si molar ratio of 1.0, followed by hydrothermal treatment at 180oC to obtain Xonotlite mineral. The obtained Xonotlite mineral was calcined at 900oC for 5 hours to form a Wollastonite owning fibre shape interlocked together to form an interconnected porous structure with a pore size of 1~2 μm, which could be suitable for industrial application.

Published: August 2022

The technique for quantification of γH2AX foci was used for studying the DNA double-strand break (DSB) of the cells exposed to ionising radiation. Peripheral blood lymphocyte and human fibroblast cells were exposed to X-ray irradiation at a dose of 2 Gy. The number of H2AX foci in cells was scored by immunofluorescence quantification using specific antibodies. An evaluation was conducted at time points after irradiation between 0 and 5 hours to determine the kinetics of H2AX foci in cells. The results showed that lymphocytes reached the highest number of γH2AX foci at 1 hour and fibroblasts at 45 minutes after irradiation. This indicated that radiation damages DNA and the repair ability of these two cell types were different. The in vitro studies of DSB of these cell types using the γH2AX assay should be performed at the above time points to ensure the stability of the γH2AX foci generated at the DSB sites.
