MATHEMATICAL MODELING OF THE RATIONAL CHOICE OF THE SIMPLEST MECHANISMS OF ECONOMIC INTEGRATION
Authors: Dilenko Viktor , Koeva Kateryna
Published: February 2021

The article concerns a certain economic and mathematical approach to the rational choice problem analysis of economic systems integration mechanisms. It is believed that the essence of integration lies in rearrangement of derived net product between the systems for their development, and the means of mentioned rearrangement determine the possible integration mechanisms of relevant economic systems. The mathematical model of two economic systems integration is built to analyse the processes of economies confunction in view of different mechanisms of their integration. At the model’s core are the elements of the well-known model of Solow economic dynamics, describing its production constituent. The model made of two differential equations systems reflecting the evolution of fixed production assets of consolidated economic systems with various mechanisms of their integration. Within the framework of the developed model is proposed an approach for rational choice of economic integration mechanisms, which relies on constructing and analyzing charts of the optimal ways of the examined economic systems confunction. There the domains of selected options of economic systems development model are represented, for which the best is an appropriate mechanism of their integration. This article presents the examples of constructing and analyzing both separate charts of the optimal integration mechanisms of economic systems and their certain sequence. It reflects the transformation processes of the corresponding areas of charts under the influence of some internal and external factors. As such factors were considered the criterion of the integration mechanism choice and the intensity of the scientific and technological progress impact. The latter comprises a kinetic component which was introduced into the constructed model and is responsible for the influence of autonomous scientific and technological progress on the development of investigated economic systems.
THE IMPACT OF CORONAVIRUS ON SMALL BUSINESS IN POLAND
Authors: Bercha Oksana
Published: February 2021

Poland has suffered less economic damage from COVID-19 than many other countries, primarily due to the rapid response aimed at supporting enterprises and population. The Polish government has adopted a set of laws – the Anti-Crisis Shield, which, in particular, provides a number of specific tools to support entrepreneurs due to the spread of coronavirus. About 90% of Polish enterprises are micro and small enterprises, of which more than half are service sector enterprises. The article analyzes selected results of a survey of Polish enterprises on the impact of coronavirus on their activities. Particular attention is paid to assessing the impact of coronavirus on micro and small enterprises (depending on the number of employees), their ability to survive in the existing restrictions applied to control coronavirus by the Polish government, currently in effect. According to the study, the thesis that small business is characterized by technological, production, management flexibility, which allows to respond quickly and in a timely manner to external influences, is not entirely true. The tendencies of stronger negative influence of the specified restrictions on small business, especially in the field of construction and retail trade, are revealed. In particular, micro and small enterprises are less likely to work remotely than medium and large enterprises; if the current restrictions imposed by public authorities to control the coronavirus continue, there is a threat to small enterprises’ survival; the largest decline in product orders is forecasted for the current month (compared to the situation if there was no pandemic).

Published: February 2021

The article analyzes the methodological approaches to making adaptive management decisions in construction, taking into account European quality standards for construction products. It was found that the civilizational choice of Ukraine, its main priority of domestic and foreign policy is full-scale integration with the European Union. The «4M» methodology is presented, which directly connects quality management with the use of the whole arsenal of management methods and management decision-making options. It is noted that one of the most important factors in the quality of construction products is effective inventory management, which reduces the duration of the production and the entire operating cycle reducing current costs for their preservation and freeing from current economic turnover of funds by reinvesting them in other assets. Ensuring this efficiency is achieved through the development and implementation of financial policies for inventory management. Emphasis is placed on the fact that one of the modern methods of making adaptive management decisions on the quality of construction products is benchmarking. Its’ application is based on the characteristics of quality management systems, guided by international and national quality management standards. Benchmarking tools have been found in order to make effective management decisions and gain a lasting competitive advantage. It is concluded that taking into account European standards the solution of effective management decisions by the construction companies’ product quality management, is based on the use of operational, marketing and economic tools that address the strategic development of construction companies in Ukraine. In turn, the path chosen by the economy of Ukraine indicates the need to comply with European standards of construction work quality, which is significantly complicated by the current state of domestic production systems.

The efficiency of the synthesis of renewable fuels and feedstocks from electrical sources is limited at present by the sluggish water oxidation reaction. Single atom catalysts (SACs) with a controllable coordination environment and exceptional atom utilization efficiency open new paradigms towards designing high performance water oxidation catalysts. Here, using operando X-ray absorption spectroscopy measurements with calculations of spectra and electrochemical activity, we demonstrate that the origin of water oxidation activity of IrNiFe SACs is the presence of highly oxidized Ir single atom (Ir5.3+) in the NiFe oxyhydroxide under operating conditions. We show that the optimal water oxidation catalyst could be achieved by systematically increasing the oxidation state and modulating the coordination environments of the Ir active sites anchored atop the NiFe oxyhydroxide layers. Based on the proposed mechanism, we have successfully anchored Ir single-atom sites on NiFe oxyhydroxides (Ir0.1/Ni9Fe SAC) via a unique in situ cryogenic photochemical reduction (in situ Cryo-PCR) method which delivers an overpotential of 183 millivolts at 10 milliamperes per square centimeter and retains its performance following 20 hours of operation in 1 M KOH electrolyte, outperforming the reported catalysts and the commercial IrO2 catalysts. These findings open the avenue towards atomic-level understanding of oxygen evolution of catalytic centers under in operando condition.

Published: February 2021

The functionalization of nanomaterials surface is key to improve their stability, reactivity and confer specific properties. However, mapping functional groups at the nanoscale remains difficult, i.e. identifying chemical nature but also spatial distribution. It is particularly challenging for organic groups and non-planar objects such as nanoparticles. Here we report a strategy for mapping amine groups on the surface of silica particles using chemically-modified gold colloids, which are used as tags to specifically and spatially identify these organic groups under electron microscopy. A complete understanding of the correlation between spatial distribution of gold colloids and chemical state of the silica particle surface (by XPS) is presented. The range of reliability of this strategy for mapping organic groups at nanointerfaces is assessed and its implications for biofunctional nanoobjects where interdistance of biomolecules are of paramount importance are discussed.

Authors: Sun Xu
Published: February 2021

The era of big data is coming, the combination of big data and traditional teaching can provide more and more accurate services for students' self-learning, and it is a good way to teach students according to their aptitude. In this background, a learning society is coming, which aiming at learning, autonomous learning and lifelong learning. Learning society emphasize the ability of learning autonomy for students unprecedentedly. Learning is no longer limited to the campus. Learning ability will accompany learners' social life and become an active and healthy lifelong activity. Autonomous learning is a learning theory that goes with the requirements of The Times and has a broad development prospect. The study of Autonomous learning not only has a very important guiding significance for the educational and teaching practice in China, but also plays an important role in the life development of every student. The subject of learning is gradually transferred from the classroom, teachers and textbooks to the students themselves. Teachers should not only impart knowledge and answer questions, but also, most importantly, teach students how to exert their autonomy in autonomous learning. After investigating and researching the existing monitoring model of autonomous English learning in colleges and universities, our group found that in practice, there is a lack of corresponding monitoring mechanisms and means, and autonomous learning has gradually become formalized. Therefore, according to the actual situation of autonomous English learning in our country's universities, the monitoring model of autonomous English learning has been reconstructed, and an effective comprehensive evaluation system has been established to effectively improve students' English learning ability.

Published: February 2021

This study aims to examine the role of managerial in firm decisions. This study recognizes that managerial plays an important role in corporate decision making. Decisions carried out by the company are not only influenced by the manager's explicit mandate to maximize firm value, but also by the manager's ability to manage the company. In previous research it was found that high-ability and low-ability managers have opposite effects on firm behavior and firm value. High-ability managers accept risk-taking whereas low-ability managers refrain from taking risks. Managerial Ability in this study was measured using DEA (Data Envelopment Analysis) while for firm risk-taking behavior using the return on assets (ROA), return on equity (ROE), and research and development costs to total assets (R&D). The model used in this study is a causality model or the relationship of influence between research variables. The proposed model is analyzed using the Structural Equation Model (SEM) causality technique. This research was conducted on manufacturing companies listed on IDX (Indonesian Stock Exchange) in 2013-2017. However, unlike previous studies, the results of this study indicate that highly capable managers play a role in minimizing corporate risk taking. This research contributes as a reference for Indonesian corporate investors and also regulators as a reflection of the effectiveness of regulations made in Indonesia.

SPECULATIVE MODELING AS A METHODOLOGICAL TECHNIQUE FOR IDENTIFYING THE REPRESENTATION PRINCIPLES OF WORLDVIEW IDEAS IN THE MEDIEVAL CARTOGRAPHY ILLUMINATION
Authors:   Russian State University for the Humanities, Krevchenko Elena V
Published: February 2021

Medieval cartography had a wide functionality. The world map served as a historiographical and didactic tool, a spiritual guide, a mnemonic matrix, a visual encyclopedia, a philosophical model, a means of meditative practices, a manuscript illustration, an exegetical and moralizing text, a method for transmitting of narrative information, ideological and pedagogical concepts. To process a vast layer of data contained in authoritative verbal sources, the rumination method was used by a medieval cartographer. And to create the map itself, it was necessary to carry out preliminary speculative modeling and solve the tasks of the artistic reproduction of the world model on a two-dimensional picture plane. An experiment in the humanities, including art history, is not a widespread method, but its application, in that case, can be effective. Taking into account the information contained in main verbal sources and following the path of the medieval cartographer, a speculative world model meeting the basic medieval worldview requirements was created in the article. Following the experiment, the basic representational principles of the image of the world were successfully identified, as well as the artistic techniques with which those principles could be applied on the visual plane were determined.

Published: February 2021

Las poéticas de la mirada han derivado en lo que podemos identificar hoy como poéticas del ojo. En el seno de las narrativas del cuerpo y en paralelo a las poéticas de la enfermedad, las autoras latinoamericanas han desarrollado en la última década una narrativa que atiende a las patologías del órgano de la vista para abordar, desde ahí, la discapacidad del cuerpo femenino junto con sus posibilidades reivindicativas. Este trabajo plantea un análisis de El cuerpo en que nací (Nettel, 2011), Sangre en el ojo (Meruane, 2012) y El trabajo de los ojos (Halfon, 2017) desde un enfoque comparatista, con el objetivo de observar el diálogo que establecen entre enfermedad, biopolítica y escritura. A partir de una reflexión sustentada en los estudios de la discapacidad y en los estudios de género, se concluye que las tres obras desafían tanto el sistema normativo de la salud como la mirada hegemónica patriarcal.

The aim of this study was to examine the effect of middle school mathematics teachers' self-efficacy and leadership styles on middle school students’ mathematical achievements and attitude towards mathematics. In this study, the general survey method was employed and the research population was consisted of a total of 917, 5th grade students, 472 girls and 455 boys, picked across 10 middle schools in a central district of a province located in North-West Anatolia. In order to gather scientific data, scales such as Mathematics Attitude Scale, Teacher’s Self-Efficacy Scale, and Mathematics Achievement Test were used. Teacher characteristics were divided into two categories which consist of two and three sub-categories respectively; autocratic and semi-democratic based on the Leadership Style Scale. And low, moderate, high level according to teachers’ scores in the Self-Efficacy Scale. The data obtained were analysed in accordance with the objectives by means of frequency, percentage, arithmetic mean, standard deviation, t test, one-way variance analysis (Ancova). The significance level in statistical analyses was set at p<0.05. Consequently, whether the teachers displayed low or high leadership styles had no significant effect on the students’ mathematical achievement and their attitude towards the subject. Teachers’ self-efficacy for classroom management sub-scale was found to have an effect on the mathematical achievement of students. The self-efficacy level of teachers for student engagement does not have a significant effect on students’ mathematical achievement. However, it was found that teachers’ self-efficacy for instructional behaviour, classroom management and student management affected students’ attitude towards mathematics. Keywords: Mathematical achievement, attitude towards mathematics, Teachers’ Self-Efficacy, Leadership Styles of Teachers.
Examining How Biology Teachers’ Pedagogical Beliefs Shape the Implementation of the Omani Reform-Oriented Curriculum

Published: February 2021

Research on science-education reform affirms the importance of taking into consideration teachers’ pedagogical beliefs in relation of the constructivist perspective to ensure successful implementation of a reform-oriented curriculum. In addition, prominent studies pinpoint the need for teachers to have sufficient pedagogical content knowledge (PCK) to adapt a reform-oriented science curriculum to meet students’ abilities and interests. This study focused on the reform-oriented science curriculum in Oman, and in particular, the grade 12 biology curriculum. The new biology curriculum emphasizes constructivism and encourages student-centered instruction, inquiry-based learning, cooperative learning, problem-solving, and critical thinking. However, since its implementation in 2008, various obstacles and challenges have been reported by teachers. These include a mismatch between the planned curriculum and the implemented curriculum. This mismatch has been attributed to a lack of motivation and PCK among teachers that would allow them to shift their teaching practices. Consequently, the purpose of this study was to understand how teachers’ pedagogical beliefs about student-centered learning have shaped their implementation of the curriculum. The study also sought to identify how biology teachers perceive the relationship between their PCK and their pedagogical decisions. An ethnographic approach to data analysis was employed, with multiple data sources including classroom observations, learning artifacts, reflections, and semi-structured interviews used. The findings of this ethnographic study indicate that Omani teachers’ beliefs and PCK shape the implementation of the reform-oriented curriculum by influencing their conceptualization of the curriculum, their identification of students’ misconceptions, their decisions about classroom teaching practices, and the level of their students’ engagement. The results of this study corroborate and expand upon previous research that suggests that teachers’ beliefs and PCK should be taken into consideration when designing and planning for new curriculum materials, teacher-education programs, and professional development opportunities. Keywords: pedagogical beliefs, reform-oriented curriculum, pedagogical content knowledge (PCK), constructivism, curriculum implementation.
