The possibility of using carbon nanofibers (CNF) in the production of aluminum matrix composite materials (AMC) by selective laser melting (SLM) has been experimentally shown. The powder composition based on the AlSi10Mg alloy with the addition of 0.5% (wt.) CNF was prepared by mechanical activation. The optimal parameters of the SLM process were determined to ensure the density of the synthesized AMC samples over 99%. The retention of CNFs in the AMC structure and the formation of Al4C3 inclusions, which have a higher strength and hardness as compared with the initial aluminum alloy AlSi10Mg, lead to strengthening of the synthesized material, the microhardness of which is 149 ± 8 HV, that is 20% higher than the hardness of the AlSi10Mg alloy.
Graça Machel: the First Lady – and Much More
Authors:   Institute for African Studies RAS, Prokopenko Liubov
Published: April 2023

The vast and diverse gallery of portraits of the First Ladies of African countries contains many bright personalities. Many of them remained socially active even after their spouses’ death or retirement. One of such positive examples is Mrs. Graça Machel, a well-known politician and stateswoman of Mozambique, the only woman in modern history who was the First Lady of two countries – Mozambique (1975–1986) and South Africa (1998–1999). A participant in the struggle for the independence of Mozambique and the first woman-minister after the proclamation of its independence, she became its First Lady but continued to work in the government, contributing to the development of the education system. After her husband’s tragic death Mrs. G. Machel continued her social activities and became a recognized activist in the struggle for the rights of women and children. She did not remain in the shadow of her second husband Mr. Nelson Mandela, President of South Africa. This African lady is an active advocate for gender equality. Her many years of active social work acknowledged with many international awards have given an additional impetus to the development of the activity of African women in their struggle for gender equality in all spheres of public and political life.

This paper applies the hidden Markov switching dynamic regression (MSDR) model to estimate transition probabilities of the Hungarian GDP between recessionary and expansionary periods. The transition probabilities are then compared to the OECD Hungarian binary business cycle indicator to assess the predictive power of the model. The paper proposes a linear model with a mean and a homoscedastic component. The level of symmetricity between the GDP and business cycles is explained by the panel data variables (Unemployment rate, IPI index, Inflation, BUX year-on-year change, and 10-3 Year sovereign bond yield spreads). It is assumed in this paper that by extending the model to encompass an exogenous variable listed in the panel data, essentially making the model bivariate, the maximum likelihood function would capture the business cycle more accurately. The results show that by plugging the unemployment rate as the exogenous variable in the regression, our model’s accuracy is 70%.
Infant-directed speech facilitates word learning through attentional mechanisms: an fNIRS study of toddlers
Authors: Zhou Xin , Wang Luchang , Hong Xuancu , Wong Patrick
Published: April 2023

The speech register that adults especially caregivers use when interacting with infants and toddlers, i.e., infant-directed speech (IDS) or baby talk, has been reported to facilitate language development throughout the early years. However, the neural mechanisms as well as why IDS results in such a developmental faciliatory effect remain to be investigated. The current study uses functional near-infrared spectroscopy (fNIRS) to evaluate two alternative hypotheses of such a facilitative effect, that IDS serves to enhance linguistic contrastiveness or to attract the child’s attention. Behavioral and fNIRS data were acquired from twenty-seven Cantonese-learning toddlers 15-20 months of age when their parents spoke to them in either an IDS or adult-directed speech (ADS) register in a naturalistic task in which the child learned four disyllabic pseudowords. fNIRS results showed significantly greater neural responses to IDS than ADS register in the left dorsolateral prefrontal cortex (L-dlPFC), but opposite response patterns in the bilateral inferior frontal gyrus (IFG). The differences in fNIRS responses to IDS and to ADS in the L-dlPFC and the left parietal cortex (L-PC) showed significantly positive correlations with the differences in the behavioral word-learning performance of toddlers. The same fNIRS measures in the L-dlPFC and right PC (R-PC) of toddlers were significantly correlated with pitch range differences of parents between the two speech conditions. Together, our results suggest that the dynamic prosody in IDS increased toddlers’ attention through greater involvement of the left frontoparietal network that facilitated word learning, compared to ADS.

Published: April 2023

Dakwah adalah upaya menyebarkan ajaran agama Islam dengan tujuan membawa manusia menuju kebahagiaan dunia dan akhirat. Dakwah tidak hanya dilakukan oleh para dai atau ulama, namun setiap muslim juga bisa ikut serta dalam melakukan dakwah. Ada beberapa jenis dakwah yang dapat dilakukan, seperti dakwah bil lisan (dakwah dengan ucapan), dakwah bil hal (dakwah dengan perbuatan), dan dakwah bil kitabah (dakwah dengan tulisan).Dalam melakukan dakwah, seorang dai harus memahami kondisi dan situasi yang ada di masyarakat, serta menyesuaikan cara dan metode dakwah yang digunakan. Beberapa strategi dakwah yang dapat dilakukan antara lain, memberikan pemahaman konseptual tentang Islam, membangun kesadaran spiritual, meningkatkan kecerdasan dan keterampilan, menggunakan bahasa yang mudah dipahami, dan menciptakan suasana yang kondusif.Selain itu, dalam melakukan dakwah, seorang dai juga harus memperhatikan adab-adab yang baik dan benar, seperti berbicara dengan sopan dan santun, menghormati pendapat orang lain, tidak menghina atau menghina, serta selalu berprasangka baik terhadap orang lain. Dengan memperhatikan adab-adab yang baik dan benar, diharapkan dakwah yang dilakukan dapat diterima dan dipahami dengan baik oleh masyarakat, serta memberikan dampak positif bagi kehidupan manusia dalam mencari kebahagiaan dunia dan akhirat.

Published: April 2023

The genus Vigna comprises very ancient pulse crops originating from Africa and Asia. The complex history and domestication of this genus are just being unraveled by help of genome sequence information. Here, we review the utilization and promising improvement strategies for mung bean (Vigna radiata), which is among the major crops in this group. It is an important legume species that is widely cultivated and consumed in many parts of the world, particularly in Asia. This crop is known for its high nutritional value, drought tolerance, and short growth cycle, which makes it suitable for cultivation in various agro-ecological zones. Despite its importance, mung bean production is often curtailed by various biotic and abiotic factors which significantly limit its yield and quality. In recent years, there has been an increased research interest in mung bean, particularly in the areas of genetic improvement, agronomy, and post-harvest management. Advances in genomic tools, molecular breeding, and biotechnology have provided new opportunities for developing improved mung bean varieties with desirable traits such as high yield, disease resistance and enhanced nutritional quality. In this review, we discuss recent developments and findings on mung bean, with a focus on genetic improvement and agronomy. We highlight the importance of developing improved varieties that are adapted to specific agro-ecological zones and resistant to biotic and abiotic stresses. Overall, mung bean research is relevant for addressing the challenges in agricultural production and food security, particularly in the context of sustainable food production in changing climate.
On Constructing Limits-of-Acceptability in Watershed Hydrology using Decision Trees
Authors: Gupta Abhinav , Govindaraju Rao , Li Pin-Ching , Merwade Venkatesh
Published: April 2023

A hydrological model incurs three types of uncertainties: measurement, structural and parametric uncertainty. For instance, in rainfall-runoff models, measurement uncertainty exists due to errors in measurements of rainfall and streamflow data. Structural uncertainty exists due to errors in mathematical representation of hydrological processes. Parametric uncertainty is a consequence of our inability to measure effective model parameters, limited data available to calibrate model parameters, and measurement and structural uncertainties. Measurement and structural uncertainties are inseparable without additional information about measurement uncertainties. The existence of these predominantly epistemic uncertainties makes the model inference difficult. Limits-of-acceptability (LOA) framework has been proposed in the literature for model inference under a rejectionist framework. LOAs can be useful in model inference if they reflect the effect of errors in rainfall and streamflow measurements. In this study, the usefulness of quantile random forest (QRF) algorithm has been explored for constructing LOAs. LOAs obtained by QRF were compared to the uncertainty bounds obtained by rating-curve analysis and the LOAs obtained by runoff ratio method. Rating curve analysis yields uncertainty in streamflow measurements only and the runoff ratio method is expected to reflect uncertainty in rainfall and streamflow volume measurements. LOAs obtained by using QRF were found to envelop the uncertainty bounds due to streamflow measurement errors. The variation of width of LOAs was similar for QRF and runoff ratio methods. Further, QRF LOAs were scrutinized in terms of their ability to reflect the effect of rainfall uncertainty, both qualitatively and quantitatively. Results indicate that QRF LOAs reflect the effect of rainfall uncertainty: increase in standard deviation with increase in mean streamflow values and decrease in coefficient of variation with increase in mean streamflow values. A mathematical analysis of the LOAs obtained by the QRF method is presented to provide a theoretical foundation.
The effect of different construct operationalizations, study duration, and preprocessing choices on power-based sample size recommendations in intensive longitudinal research
Authors: Lafit Ginette , Revol Jordan , Cloos Leonie , Kuppens Peter , Ceulemans Eva
Published: April 2023

To shed light on the dynamics of psychological processes, researchers often collect intensive longitudinal (IL) data by asking people to repeatedly report on their momentary experiences in daily life. Two important decisions when designing an IL study concern the number of persons and the number of measurement occasions to be included. These sample size decisions are ideally based on statistical power considerations. When conducting statistical power analysis, it is necessary to provide the value of the effect size of interest as well as of all other model parameters. In IL research these values have to be based on previous studies. This implies that these values are subject to large heterogeneity due to differences in study design and preprocessing choices. This between-study heterogeneity can severely impact power-based sample size recommendations. In this paper, we introduce an approach to investigate the impact of study design and pre-processing of previous studies and to determine a recommended sample size to account for this impact. We demonstrate how to use this approach to investigate the effect of different construct operationalizations, study duration, and preprocessing choices. This approach paves the way for more thoughtful and robust sample size decisions.
Normative Conflict and Normative Change
Authors: Noblit Graham Alexander
Published: April 2023

Human life is riddled with norms, many though not all of which are costly for individuals to adopt. Similarly, human ecological adaptation relies on costly-behaviors that often generate non-rivalrous and non-exclusionary benefits for group-members. Yet, in a dynamic world, innovations, environmental change, and information-revelation mean that what norms are beneficial for a group to adopt will inevitably change over time. However, multiple game-theoretic models studying the various mechanisms stabilizing normative behaviors have demonstrated that the stability of a norm does not depend on the benefits it confers. In turn, explanations of normative change have either relied on group-selective mechanisms to explain the presence of adaptive norms or have failed to identify conditions under which normative change occurs. We study normative change by means of costly-punishment and conflict resolution. We identify social differentiation in goals and punishment capacity as a key condition permitting normative change. While normative change that results from such social differentiation need not be group beneficial it will be beneficial to some subset of agents in the population. We additionally discuss how the intra-societal forces of normative conflict that we study might interact with group-selective forces and in turn determine the dynamics and outcomes of group-selection.
A History of Untouchability in Nepal
Authors: Kafle Dol Raj
Published: April 2023

This study tries to explore how the practice of untouchability developed in the ancient Indian Aryan society and over time entered Nepal and gradually took root in Nepali society. This study presents an argument based on historical facts that the practice of untouchability originated in the Indian Aryan society under the practice of some of the elites who had been in powerful positions. The practice was mainly instituted by the elites to continue exercising their power to subjugate the powerless. As the same, elite Aryans started migrating to Nepal during the ancient period, they brought with them the same practice to continue exercising self-acquired power within the Nepali society. But there was no strongly practiced untouchability in ancient Nepali society. The practice was slowly instituted with the adoption of associated rituals and traditions. The main objective of this study is to explore and analyze untouchability from a historical perspective. The custom of untouchability has existed in Nepal for centuries, there is limited historical evidence of any efforts to abolish it during the ancient and medieval periods. This study combines a qualitative research approach and a historical framework to explore the connection between a social norm and its history.
Toward Understanding Impacts of Virtual Visits on Accreditation Review Effectiveness, Quality, and Best Practices
Authors: Haughery John R. , Doggett A. Mark , Mosher Gretchen A , Hildebrant Jake
Published: April 2023

Accreditation standards and criteria motivate much of the efforts to continuously improve public higher education institutions in the United States. A key mechanism in this accreditation process for many agencies is an onsite physical visitation of the institution and/or program by an accreditation visiting team. This visit can provide tangible information, observation, and characterization of the institution or program under review, which informs a final accreditation decision. Due to the 2019 coronavirus disease (COVID-19) pandemic and the ensuing travel and physical distancing protocols, many accrediting agencies were required to hold traditional onsite visits virtually during the spring of 2020.Not only was this an ad hoc transition, but it was also made without full knowledge of the impact that the shift in evaluation mode would have on the effectiveness and quality of accreditation reviews against accreditation standards and criteria. Therefore, a critical need exists to evaluate the efficacy of the virtual mode of accreditation review. This study analyzed the impacts of virtual site visits on accreditation review effectiveness and quality. Using survey data collected from the Association of Technology, Management, and Applied Engineering (ATMAE)’s Board of Accreditation, from visiting team members, and from institutional contacts involved in the 2020 accreditation visits, an assessment of the effectiveness and quality of accreditation reviews was performed. Qualitatively, strong themes were found in the data set revealing the impacts of the virtual modality on accreditation review effectiveness and quality; advantages, disadvantages, and opportunities to leverage the remote modality were also discovered and are highlighted. Quantitatively, the virtual modality was overwhelmingly reported to be effective for most accreditation standards, whereas impacts on quality were more negligible. The results of this study help characterize the impacts on accreditation amid the COVID-19 pandemic, provide a picture of lessons learned from the use of this modality, and begin to lay a preliminary foundation for best practices for future virtual accreditation site visits.

This research focuses on analysing the impact of competitiveness as measured through the Lerner competitiveness coefficient, operational efficiency, and risks to financial stability through the Z-score bankruptcy risk ratio of Vietnam’s leading prestige construction groups in the context of economic integration. From there, the extent of the influence of factors on the long-term stability and development of corporations operating in the construction sector is inferred. The research data was collected from audited annual financial statements of 17 construction companies operating between 2013 and 2020, with a total of 136 observations. The main research method of this work is the application of SEM linear structure modelling for panel data in multivariable regression analysis. The final results of the study show that most impact variable groups have an influence on the stability of the business. In addition, the results of the study provide an answer on the competitiveness index as having a positive effect in promoting the financial stability of enterprises in the short term. Conversely, if a business abuses this index in the long term, a reaction against the expectations of managers will occur.

Published: April 2023

Abstract.The purpose of the article is to conduct an assessment of investment activity in Zakarpattia region on the basis of statistical information - an indicator of the policy of the regional authorities in the field of investment climate formation as a condition of high competitiveness.The study showed that recently there has been a sharp drop in investment activity in Zakarpattia. In 2020, the trend, which was aimed at growth, sharply went down. This indicates the deterioration of the investment climate in the region and, accordingly, the drop in the level of competitiveness of the region.The conducted analysis proves that insufficiently active investment policy in the region is due to the following reasons.First of all, in Zakarpattia, any investment, especially in the innovation field, should have a high financial return. Due to the lack of data on investments in the innovation sphere, the amount of investments in the region as a whole was chosen for analysis. As a result, an examination of the level of profitability of regional business was carried out using the indicator of the share of enterprises that received losses for the year. The share of enterprises in the region that ended the year unprofitable in 2020 is more than 25%, that is, every fourth enterprise operates without a profit. Due to the fact that the product of innovative activity, as a rule, has a high profitability, it is possible to conclude that investments in innovative activity are not decisive in the total amount of investments.Secondly, investments in innovative activity are highly risky, so the appropriate financial results should cover the degree of uncertainty and the possibility of financial fiasco.In addition, the reason for the investment climate that does not meet modern requirements is the inadequate financial condition of regional enterprises. The study showed that the region has low liquidity and solvency of enterprises. The amount of liabilities is much higher than equity, which indicates the extremely poor solvency of Transcarpathian enterprises.Low financial stability of a business is a marker of a possible pre-bankruptcy state. If the financial stability of the business is in question, the infusion of any investment is also a high-risk action, the implementation of which requires a change in management, policy, strategy, etc., which, in turn, determines the need for time and additional financial investments.Keywords:region, competitiveness, investment climate, solvency, profitability.

Distance learning during the pandemic era: Russian instructors’ experience
Authors: Sadykova G. V. , Severyanov O. I.
Published: April 2023

The article focuses on studying Russian university instructors’ experience acquired during the emergency remote learning period in 2020–2021. The need to adjust the development route of the distance learning system determines the topicality of the research. The novelty of the article is determined by significant gaps in scientific literature concerning studying, generalizing, and comprehending such experience.

The study employed quantitative and qualitative methods of data collection and processing. Russian university instructors (N = 57) filled in an online questionnaire which aimed to identify the advantages and disadvantages of distance learning. Corpus linguistics methods were used to outline the most common key themes, which made it possible to identify the frequent words employed to describe positive and negative experiences. Responses to open-ended questions were examined using contextual and content analysis.

The most significant positive aspects of the online format identified by the respondents included travel time saving, extending the repertoire of teaching strategies and access to visual methods of presenting information thanks to the online platform technological capabilities. This enabled instructors to involve usually silent students in active communication. Moreover, the respondents cited safe communication during the spread of a viral disease as well as students’ constant access to information resources. As for disadvantages, respondents mentioned a marked deterioration in interaction with students due to the lack of personal and/or visual contact, technical communication problems, and labor intensity. Other often cited drawbacks were difficulties in developing practical skills and effectively monitoring students’ knowledge and psychological state, learners’ decreased motivation as well as health problems.

Based on the results of the study, the article concludes that it is necessary to improve instructors’ professional competencies and improve technical facilities of educational institutions. This would provide access to and usage of multifunctional distance learning management systems and programs that permit videoconferencing, file sharing and demonstrating multimedia presentations and online materials.

The research is relevant as it is important to study and summarize instructors’ positive and negative experience to improve professional development programs, make decisions on purchasing and using equipment and software, and change university development agendas.
Students’ resolutions of some paradoxes of infinity in the lens of the grossone methodology
Authors: Nasr L.
Published: April 2023

In the article, students’ responses to some classical paradoxes related to infinity were investigated by considering the traditional methods and later by considering a new methodology for dealing with infinity (grossone methodology) which was introduced to them briefly. Eleven students of grade 12 participated in this study.

In phase 1, the students (who study in the traditional methods) provided their intuitive resolutions to three paradoxes of infinity. In phase 2, the students were introduced to the grossone methodology after which they were asked to resolve the same paradoxes using this methodology in phase 3. After being presented by the normative and the grossone-based resolutions, the students reflected on them inwriting.

Results of this study showed that students’ intuitive solutions were similar to grossone-based solutions of the three considered paradoxes. Therefore, the students accepted those solutions.

This study shows the relevance of using an alternative method, which is the grossone methodology, in order to simplify resolutions of some paradoxical situations with infinity for undergraduate students.
Elements of a polyprogram methodology of teaching the theme "Creation and processing of text information" using the free office package LibreOffice at the level of basic general education
Authors: Markushevich M. V.
Published: April 2023

The article presents the author's polyprogram methodology of teaching the theme "Creation and processing of text information" for teaching informatics at the level of basic general education. The methodology is based on the use of four main components of the free cross-platform LibreOffice office suite: LibreOffice Writer text editor, LibreOffice Math mathematical formula editor, LibreOffice Calc spreadsheets (for creating diagrams), LibreOffice Draw vector graphics editor (for creating drawings and diagrams).

The relevance of the work is determined, first of all, by the tightening of economic sanctions against Russian engineering universities by the governments of a number of Western countries in 2021, which consists, in particular, in the refusal of proprietary software developers to provide a license to use their software, as well as the need of domestic education in informatics teaching methods that are insensitive to the form of education (full-time, distance), suitable for use in the conditions of a sudden transfer of the educational process to a distance form due to a pandemic or other critical factors.

The developed elements of the methodology mean a stack of practical tasks, during which students develop the set of digital skills necessary to create complex combined multi-page text documents. Moreover, the development of these skills takes place both in the classroom and when performing practical homework tasks. The article describes this set of practical tasks simultaneously with the tools used for these purposes and the functionality of LibreOffice Writer.
Using plot tasks when teaching Python programming
Authors: Koltsova K. I.
Published: April 2023

The article deals with the problem of increasing the internal motivation of schoolchildren when studying programming. The traditional techniques that increase motivation include appealing to the life experience of students, creating a problem situation, solving plot tasks, modeling real events in the educational process (role-playing games). One of the requirements for tasks with applied content is the correspondence of the plot to the age characteristics of students. The fulfillment of this requirement will be possible if the situation described in the plot of the task is socially significant for adolescents, takes into account their interests and current trends in adolescent communication. The article provides examples of plot tasks, the use of which is expedient when teaching programming to basic school students. These tasks allow students to get acquainted with the "list" and "dictionary" data structures, with a pseudo-random number generator, and with creating their own modules in Python.

Research works devoted to the identification of species composition of the mycobiota of the Ural River valley within the West Kazakhstan region (WKR) were carried out in the forest communities of the region from 2019 to 2021. On the basis of field studies, a mycological description of black poplar (Populus nigra) forests, which are the main forest-forming species of the studied territory, was carried out for the first time. Also, there was carried out a geobotanical description of the main black poplar communities. The study area is located within two botanical and geographical regions such as in the Eurasian steppe and Saharo - Gobi desert zones, the Holarctic kingdom, on the border of the Boreal and Ancient Mediterranean subkingdoms. Throughout the floodplain along the Ural River poplar forests are the dominant species. When studying the diversity of macromycetes in the biota of cap fungi of black poplar forests, there were registered 42 species of macromycetes belonging to 32 genera and 19 families, 7 orders of the class Agaricomycetes. Ecological-trophic analysis showed a predominance of xylotrophs (18 species, 42,9 %) and humus saprotrophs (13 species, 31 %) over mycorrhizal (11 species, 26,1 %).) According to the results of the study, it can be assumed that the species composition of macromycetes is significantly influenced by the geographical position of the region, the geomorphological structure of the Ural River, as well as the soil-climatic and hydrological conditions of the region. The taxonomic composition of macromycetes collected and identified in the study area is presented for the first time for this area.

It is well known that as a result of the activities of the mining industry, radionuclides and chemicals with active mutagenic and carcinogenic effects can be extracted to the surface. Disposal products, such as radioactive waste and others, may cause particular danger. In this regard, this requires regular monitoring of radioactive waste storage sites and the degree of migration of radionuclides and heavy metals in environmental objects. This review article considers the uranium ore region’s current data for the content of radionuclides in soil, vegetation, and their migration in the “soil-plant” chain.

Environmental stress is a major area of scientific interest because it limits the productivity of both plants and crops. Anthropogenic activities have exacerbated the issue even more. As a result, salt stress appears to be a significant barrier to plant and crop productivity. Salinity has a variety of effects on plants, including osmotic effects and ion-specific toxicity, as well as proline accumulation and sulphur assimilation. Plants known as halophytes have a high salt tolerance, allowing them to survive and thrive in extremely saline conditions. The study of halophytes aids our comprehension of important adaptations required for survival in high salinity environments. Therefore, enhancing plant salt tolerance as well as increasing agricultural yield and quality of crops in saline lands is of vital importance. Here, we look at what we know about how salinity affects plant metabolism and how plants deal with it.
