Authors: Rahimi-Ajdadi Fatemeh , Khani Mahdi 
Published: June 2022

Abstract
Over the last decades, north of Iran underwent remarkable land use/cover changes due to socio-economic and environmental factors. This study, focused on agricultural land changes for the period of 1990–2020 at Shanderman, Iran, employed Landsat 5 TM, and Landsat 8 OLI/TIRS images. A supervised maximum likelihood classification technique was utilized for the purposes of satellite data classification to four classes: agricultural land, forest, grassland, and built-up area. Results of land change modeller showed that, during the last three decades, agricultural land, grassland and forest decreased by 42.81%, 35.50%, and 4.05%, respectively, while built-up area increased by 361.23%. Most of the losses in agriculture areas occurred in 1990–2011 (44.64%). The predominant losses in 2011–2020 belonged to the forestland (12.47%), making them approx. 3.44 times higher than in 1990–2011. The results highlight the need for serious attention to the deforestation phenomenon, which leads to the conversion of forest into agricultural and built-up areas.

Authors: Meddour Ahmed Salah Eddine , Souas Farid 
Published: June 2022

Abstract
A study of the flow behavior of Algerian crude oils obtained from different fields in the TFT region (Tin Fouye Tabankort/South Algeria) was conducted using the AR2000 rheometer equipped with a Couette geometry. Rheology experiments were carried out at different shear rates and temperatures to predict the transport characteristics of crude oils. The results obtained show that all crude oils studied exhibit non-Newtonian behavior at low shear rates and quasi-Newtonian behavior at high values of the shear rate gradient. The analysis of the obtained rheological data revealed that the increase in temperature had a positive effect on the flow behavior of crude oils in pipelines.

Published: June 2022

Abstract
Among the different nanostructures that have been demonstrated as promising materials for various applications, three–dimensional (3D) nanostructures have attracted significant attention as building blocks for constructing high-performance nanodevices because of their unusual mechanical, electrical, thermal, optical, and magnetic properties arising from their novel size effects and abundant active catalytic/reactive sites due to the high specific surface area. Considerable research efforts have been devoted to designing, fabricating, and evaluating 3D nanostructures for applications, including structural composites, electronics, photonics, biomedical engineering, and energy. This review provides an overview of the nanofabrication strategies that have been developed to fabricate 3D functional architectures with exquisite control over their morphology at the nanoscale. The pros and cons of the typical synthetic methods and experimental protocols are reviewed and outlined. Future challenges of fabrication of 3D nanostructured materials are also discussed to further advance current nanoscience and nanotechnology.

Then, we give an example to illustrate the main results.
International Differences in the Perceptions of Export Obstacles By SMEs in the Same Firm-Level Characteristics: Evidence from European Countries
Authors: Civelek Mehmet , Polách Jiří , Švihlíková Ilona , Paták Milan 
Published: June 2022

Abstract

Research background: Most of SMEs encounter many impediments when performing direct exporting activities. This is because various countries have different legislative and tax burdens and cultural-linguistic diversities that create export barriers for SMEs from other countries. Even SMEs that are the same size, age, from the same sector or legal form, their perceptions of export obstacles might differ depending on countries where they are located.

Purpose: This research investigates the differences between the export obstacle perceptions of SMEs from different countries but with the same firm-level characteristics

Research methodology: To achieve this aim, the researchers apply a random sampling method to determine the research sample. Moreover, the researchers created an online questionnaire to gather the research data. Finally, 408 SMEs from the Czech Republic, Slovakia and Hungary have been analyzed by performing a Kruskal-Wallis analyses with the Dunnett T3 Post Hoc Test to achieve the aims of the research.

Results: The empirical results express the differences and the similarities between the perceptions of export obstacles by SMEs. While the perceptions of Czech-Hungarian and Slovak-Hungarian SMEs do not differ in any same firm-level characteristics, the differences exist between Czech and Slovak SMEs that are smaller in size, older and, that have limited liability and sector categories. Compare with their Czech counterparts in these categories, Slovak SMEs perceive export obstacles less intensively. The approaches of a government on SMEs and investment freedom in a nation and the exporting patterns of SMEs might be the reasons for these similarities and differences among SMEs in various countries which are in the same age, size, sector and legal form categories.

Novelty: The significant results that this research proves in same firm-level characteristics and an international context makes this paper unique research in the literature. Therefore, policy makers, academicians, SMEs, and financing institutions might gain many benefits from the findings of this study.
The Impact of Firm Size on Corporate Indebtedness: A Case Study of Slovak Enterprises
Authors: Gajdosikova Dominika , Valaskova Katarina 
Published: June 2022

Abstract

Research background: Debt is considered a normal part of enterprises these days. If enterprises do not have enough equity, they will start to use a large amount of debt which is mainly associated with indebtedness. Rising indebtedness can be a difficult financial situation for business entities in the form of default and inability to meet their liabilities.

Purpose: The main aim of this paper is to perform a debt analysis of enterprises operating in sectors that are considered leading in the conditions of Slovakia, such as the manufacturing and construction sector, and subsequently, to examine whether the size of the enterprise has a significant impact on selected indebtedness ratios.

Research methodology: Firstly, the debt analysis was performed using the six selected indebtedness indicators on a sample of 846 enterprises. Secondly, a more detailed analysis, focused on examining the existence of statistically significant differences between individual indebtedness ratios concerning the size of the enterprise, was realized using the non-parametric Kruskal-Wallis test. At the end of the research, the Bonferroni corrections were used to identify where the stochastic dominance occurred.

Results: The impact of the enterprise’s size on the calculated indebtedness indicators is confirmed by the results of ANOVA, based on which it can be argued that statistically significant differences between the calculated indebtedness indicators exist between large and small enterprises, as well as an inequality of medians between large and medium-sized enterprises. As a result, the median values of the debt ratios of small and medium-sized enterprises are the same.

Novelty: The contribution of this paper is a new feature of the application of debt analysis for the evaluation of corporate performance. There are only a few papers in Slovakia that focus in detail on an analysis of the indebtedness of individual enterprises and with an examination of the determinants that affect this indebtedness, which is, however, an added value of our contribution.

The Nexus Between Bank Credit Risk and Liquidity: Does the Covid-19 Pandemic Matter? A Case of the Oligopolistic Banking Sector
Authors: Magwedere Margaret Rutendo , Marozva Godfrey 
Published: June 2022

Abstract

Background: There is a raging debate on how the COVID-19 pandemic disrupted the financial market environments, affected the banks’ strength as the credit channel, and the nexus between market liquidity and credit risk. During the COVID-19 crisis in the banking sector, credit risk and liquidity risk cannot be ignored as they have a considerable bearing on the performance and survival of banks.

Purpose: Within the context of COVID-19, bank-specific and external factors were examined to determine the relationship between liquidity and the credit risk of South African domiciled banks.

Research methodology: Quarterly panel data from 13 South African domiciled banks from 2018 to 2021 were examined using panel data methodologies: fixed effects and the system GMM.

Results: In an analysis of the period between 2019Q1 to 2021Q1 the results suggest a positive relationship between liquidity and credit risk, the COVID-19 pandemic was found to have an implication on the nexus as the COVID-19 dummy variable was significant. Also, the results show that liquidity deteriorated with an increase in COVID-19 cases during the pandemic period. During the Pre-COVID-19 liquidity improved with a decrease in credit risk. Nevertheless, during COVID-19 liquidity was not influenced by credit risk. The results are contrary to the pre-COVID-19 period as the government interventions to support households and non-financial firms could have changed the dynamics of liquidity and loan losses.

Novelty: The pandemic has ushered in a novel set of responses whose lasting impacts are not yet certain. The originality of the article lies in the nature of the investigation, where the nexus between liquidity and credit risk under the COVID-19 shocks/pandemic set-up. This is a unique study as the study revealed that policymakers and researchers alike should pay particular attention to the vulnerabilities to shocks from within and outside of the financial system as COVID-19 was found to significantly affect liquidity and credit risk. Since the pandemic is still active, further research is necessary to examine the cointegrating and causal relationship in the long run.
An Analysis of Household Income in Poland and Slovakia Based on Selected Income Models
Authors: Trzcińska Kamila 
Published: June 2022

Abstract

Research background: Studies of income distributions may focus on describing empirical distributions by theoretical models. This approach can be useful for many reasons. When choosing a statistical model, it is important both to find out a theoretical distribution function that would characterize empirical frequency distribution and to choose suitable methods to calculate the parameters of the model. In the literature, there are proposals for various types of mathematical functions. Very high accuracy with empirical distribution is characteristic for Dagum and log-normal models. In 2010 Zenga proposed a new three-parameter model for economic size distribution which possesses interesting statistical properties.

Purpose: The aim of this paper is to apply and compare Dagum, log-normal and Zenga models to income distributions in Poland and Slovakia.

Research methodology: The studies are based on research data from the European Quality of Life Surveys (EQLS), whose purpose is to measure both objective and subjective indicators of the standard of living of citizens and their households. The estimation parameters were obtained by means of the maximum likelihood method and D’Addario’s invariants method.

Results: The results of the conducted approximations, presented in the paper confirmed the good consistency of the Dagum and Zenga distributions with the empirical income distribution of households in Poland and Slovakia.

Novelty: The Zenga distribution was used for the first time to describe the income distribution of the Slovak population and it allows the best fit to the empirical data of this country.

Authors: Muwakhid B. , Kalsum U. , Wati A. M. 
Published: June 2022

The problem that often comes by farmers is a shortage of feed in the dry season; one of the technologies that can be used is silage. Carrot straw (CRS) can be used as a silage material because of its abundance and nutritional value, which is good for the livestock. The purpose of this study is to know about the differences in the provision of feed additives, i.e., Lactobacillus casei-A, Lactobacillus plantarum, and Lactobacillus casei-B of the composition of CRS silage. Making silage by means of CRS was weighed, CRS was placed on a tray and added with feed additives based on experimental treatment, CRS was mixed thoroughly, stored, and closed in a laboratory-scale silo then placed at 26-28oC. CRS was given with three different feed additive treatments: CRS + 0.01% Lactobacillus casei-A, CRS + 0.01% Lactobacillus plantarum, CRS + 0.01% Lactobacillus casei-B. Ensiling was carried out for 21 days in four replications for each treatment, and each replication was made in duplicate. Statistical analysis after the data was obtained was using the SAS University application specification 4.0 red hat (64-bit) with code, and the difference between the treatment means (P<0.01) was determined using Duncan’s Multiple Range Test (DMRT). This study resulted that the different types of use of lactic acid bacteria had a significant effect (P<0.01) on organic matter content (OM), crude fiber content (CF), extract ether content (EE), nitrogen-free extract (NFE), neutral detergent fiber (NDF) and acid detergent fiber (ADF). This study concludes that the difference in the provision of feed additives affects the chemical composition of carrot straw silage. To sum up, Lactobacillus casei-A has a good value on NFE while Lactobacillus casei-B has a good value on OM, CF, EE, NDF, and ADF.
SOCIAL EXPECTATIONS OF YOUNG PEOPLE: FROM THEORETICAL CONSIDERATION TO PRACTICAL APPLICATION IN WAR AND POST-WAR PERIOD
Authors: Savelchuk Iryna 
Published: June 2022

The current state of research of the phenomenon of social expectations is analyzed, which made it possible to highlight the essence and features of social expectations of adolescents and young people. It is established that the existence of different approaches to understanding the concept of «social expectations of young people» is a reflection of the evolution of the phenomenon itself. The concept of «social expectations» does not have a clear theoretical and methodological definition, which complicates the implementation of the procedure of monitoring and evaluation of its results, in particular in martial law and postwar. It was found that the determinants of their implementation may be the characteristics of the young person (age, gender, region and place of residence).
It is shown that the focus on the future reflects promising areas of realization of social expectations. Taking into account the threats and challenges of martial law and post-war future orientation of young people leads to changes in values (education, work and career, cooperation, service), social (equality, social justice, national identity, patriotism, helping others), life (sustainability, strategic, self-efficacy, locus of control) and family (marriage, family and parenthood) perspectives.
The purpose of the study: to analyze modern theoretical approaches to understanding the phenomenon of «social expectations of young people» and identify promising areas of social expectations related to the measurement of threats and challenges of the war and postwar period.
The results of the study provide a theoretical expansion of the construct of «social expectations» by finding indicators of specific characteristics and factors of their formation, taking into account age, gender, environmental and regional aspects.
"Indigenous peoples" as a constructive concept: discourses and practices
Authors: Mosolova Lyubov' Mikhailovna , Bondarev Aleksei Vladimirovich , Zykin Alexey 
Published: June 2022

The authors of the article, having considered a series of migrations of large and small peoples to different regions of the world, found out that the change of territories of their habitat during periods of long duration was a permanent historical process. Throughout the history of mankind, individual ethnic groups and sometimes even entire peoples have changed their places of residence for one reason or another, moving in many historically recorded cases to the territory already inhabited by other peoples, coming into contact with these peoples and developing in each case various (constructive or destructive) forms of interaction. This was the case in the past, these processes continue in the present and there is every reason to assume that this will happen in the future. The term "indigenous peoples" has a certain meaning only within the framework of colonial and postcolonial discourse, outside of these limits, this term is either heuristically meaningless, or acquires an instrumental-biased and even speculative character. Nevertheless, the vagueness and dubiousness of the term "indigenous peoples", oddly enough, does not prevent its use in scientific discourses, in solving identity problems, in ethnopolitical, socio-economic and international legal spheres. The authors have revealed that this is due to the processes of mythoconstruction of national histories by small and large peoples and, to a certain extent, geopolitical interests.The more you delve into the analysis, the more you become convinced that the concept in question is not only not heuristically significant in scientific terms, but is also often used in large-scale socio-cultural myth-making, for political and geopolitical purposes, in fueling interethnic conflicts, in inciting national enmity and other similar situations. This dubious concept is anti-historical and dangerous for the process of preserving the peaceful and sustainable existence of peoples within and between States.

Published: June 2022

Для создания условий для адаптации младших школьников педагогу важно помочь ребенку приспособиться к новым условиям в рамках учебного учреждения. Успех коррекционной работы в этом направлении во многом зависит от уровня развития познавательных процессов ребенка, от его интереса к тому или иному виду работы, в том числе и учебной деятельности. Для выявления адаптированности первоклассников к школе проведено исследование по изучению деятельности педагога в направлении адаптации детей младшего школьного возраста к условиям школы. В исследовании была применена коррекционная программа для повышения уровня адаптации.
To create conditions for the adaptation of younger schoolchildren, it is important for the teacher to help the child adapt to the new conditions within the educational institution. The success of correctional work in this direction largely depends on the level of development of the child's cognitive processes, on his interest in a particular type of work, including educational activities. To identify the adaptability of first-graders to school, a study was conducted to study the activities of a teacher in the direction of adapting primary school children to school conditions. In the study, a correction program was applied to increase the level of adaptation.

Authors: Backhaus Simon Karl Hubert , Nadarajah Devika 
Published: June 2022

The purpose of this paper is to compare small- and medium-sized enterprises (SMEs) against largeenterprises (LEs) in terms of their productivity enhancements through Fourth Industrial Revolution(IR4) technologies, specifically in the context of developing countries.This study adopted a quantitative approach. Questionnaires were distributed to Malaysian manufacturers registered under Malaysia External Trade Development Corporation MATRADE via email and in-person at the Smart Manufacturing Uprising conference in Kuala Lumpur. A total of 76valid responses were obtained and analyzed using multiple regression.SMEs’ productivity was found to have significantly increased due to the Internet of Things and digital automation without sensors, while LEs’ productivity revealed a significant improvement fromintegrated engineering systems.The small sample size of 76 raises generalizability issues. Thus, large-scale quantitative research isrecommended to validate the relationships identified in this study.The study is among the first to identify and compare the significant relationships between IR4technologies and productivity enhancements among SMEs and LEs. The findings are of interest to academics as well as to public and private sector practitioners in directing resources to technologiesthat enhance productivity.
