e-Learning in Higher Institutions and Secondary Schools during Covid-19: Crisis Solving and Future Perspectives
Authors: Brozović Mateja , Ercegović Marina , Meeh-Bunse Gunther
Published: November 2022

Background: The pandemic of Covid-19 brought significant changes to the education system and forcibly accelerated the process of digitizing teaching. Students and educators had to adapt to the new way of education, facing challenges such as technical problems and a lack of technical skills and social contact.

Objectives: The purpose of the paper was to explore the attitudes of the university and high school educators and students towards the pandemic’s impact on digitization in teaching.

Methods/Approach: Data were collected through a questionnaire distributed to university and high school educators and students in Croatia, Poland, Serbia and Germany in the field of accounting, finance, trade, tourism, and other areas of interest, resulting in 2,897 responses. The results were analyzed using descriptive statistics and non-parametric tests.

Results: The research showed that: 1) high school students were less optimistic about the positive impact of the pandemic on applying digital tools in teaching than university students, 2) educators generally prefer traditional exams, while students generally prefer e-exams, 3) a higher proportion of university respondents believe that e-learning should be used as an important addition to traditional teaching when compared to high school respondents.

Conclusions: The pandemic has changed how the teaching process will be performed, but we should learn from experience and address the issues with e-learning.
Franz Liszt and the Temple of Art
Authors: Veres Bálint
Published: November 2022

Is it possible or desirable at all to establish a museum for music? The question was first posed by Franz Liszt in the 19thcentury. This essay will not only present the background and context of the question, but also the contradictory conclusions that emerge from the idea of the musealisation of music, and which still linger in 20th-and 21st-century music culture.
What are we Speaking of? A New Perspective on the Post-verbal Field in Hungarian
Authors: Driussi Paolo
Published: November 2022

Hungarian displays a characteristic syntax, that within the generative approach was called non-configurational. For this reason its description is at least unusual, and it cannot be taught with the same formal concepts used for most of the other European languages.

Functional approaches, with Functional Discourse Grammar among them, seem to be especially useful in both describing and teaching Hungarian, because they allow the interplay between pragmatics, syntax and semantics. This article sets the most important traditional assumptions about Hungarian syntax within the functional approach, concentrating on issues with word order. It is suggested that the so-called post-verbal field is very important. The central claim is that in a Hungarian sentence not only is the context of the expression recognized, given by the Topic and a possible Focus of communication, but also a distinct target of our discourse: a constituent signalling what we are speaking of that facilitates the making of the sentence.
Comparative Analysis of Genitival Components in Time Metaphors
Authors: Máthé Zsuzsa
Published: November 2022

Such a universal yet abstract concept as time can show variation in metaphorical language. This research focuses on metaphorical language within the framework of the cognitive metaphor theory, investigating the image of time through a contrastive cross-linguistic approach. This study attempts to identify genitival components associated with time in a metaphorical context, with a focus on image-based metaphors e.g. the teeth of time or the river of time. The hypothesis is that certain patterns of lexicalization of cognitive processes related to time could differ in Hungarian, English and Finnish, and to support this claim cognitive underpinnings of metaphors are investigated using an empirical corpus-based method.

Lectures become the center of learning who dominate the activities in traditional classrooms. Most of the learning time in the classroom is spent on lecturing than students' activities which causes a lack of motivation in learning. The study aims to: 1) increase activities of both the lecture and students by implementing Flipped Classroom; 2) to increase students' motivation by implementing Flipped Classroom; 3) to increase students' learning achievement by implementing Flipped Classroom. The study used a classroom action research methodology which consisted of 3 cycles. There were four stages in the research: planning, implementation, observation, and reflection. Data of the study consisted of 1) activities data of both lecture and students through observation and documentation; 2) students' motivation data through online questionnaires on Google Form and observation; 3) learning achievement through an online quiz on Edmodo. At the end of Cycle III, it was found out that there was an increase in activities of both lecture and students, student motivation, and learning achievement by implementing Flipped Classroom.
Logics of Collaboration
Authors: Wixom Jacob Hartt , Dahlin Eric , Child Curtis , Mattson Christopher A.
Published: November 2022

Participatory design approaches such as co-design are promoted as ways to increase the likelihood that engineered products are economically, environmentally, and socially sustainable by incorporating stakeholders into decision-making processes. However, executing collaborative design practices that incorporate the variety of stakeholders represents an enormous challenge. In this paper we examine these realities as experienced by a co-design team comprised of design engineers from a foreign country who are engaged with local stakeholders to develop a product for a community in the Brazilian Amazon. Based on more than a year of ethnographic research, we identify three types of perspectives or institutional logics operating in this setting—engineering, modernization, and traditional—which interact to constrain and enable the co-design process. We find that these logics can undermine co-design because the design team is better equipped to respond to stakeholders who express modernization logics rather than traditional ones. We conclude that while co-design can be truly collaborative in development projects, other times it may lead to the appearance that the design process is collaborative when it may in fact mask the marginalization of certain stakeholder voices.
Beginning Early: Reflective Practice Development in a Pre-health Course on Health Literacy and Health Disparities
Authors: Lounsbery Jody L. , Milone Anna , Fenimore Claire , Pittenger Amy L.
Published: November 2022

Background: Learning reflective practices and understanding the complexity of health literacy and health disparities need to start early in health professions training. The primary objective of this inquiry was to evaluate the feasibility and effectiveness of using reflection categorization for assessing learner progression on reflective practice development. The secondary objective was to evaluate student reflection as a strategy for introducing and advancing pre-professional learners' understanding of health literacy and health disparities.
Case Description: Within an online undergraduate health literacy course, two written reflection assignments were coded using Kember’s four categories: habitual action, understanding, reflection, and critical reflection. Students received feedback based on this reflection categorization to promote development of reflective practices. However, reflections were not graded using the reflection categorization.
Case Themes: Most (78%) students were at the level of understanding for the first reflection. For the second reflection, 29% of students were at the reflection level, demonstrating health literacy application and describing the important contributing role of personal context to health outcomes. Sixteen (33%) students progressed in their level of reflection. Within the reflections, students discussed knowledge gained and plans for future application.
Conclusion: Using a structured reflection activity allowed pre-health students to begin developing reflection practices. Through reflection, students were able to describe and apply health literacy and health disparities knowledge.

Enhancement of shoot organogenesis in Polygonum tinctorium by sucrose and gelling agents
Authors: Park Sang Un , Kil Ki Jung
Published: November 2022

Indigo (Polygonum tinctorium), though it is a medicinal and dye crop, can also be grown in temperate areas, especially because it is commonly disseminated in Japan. To date, much research has been considered under investigation, especially for the regeneration of the indigo plant. Here in this study, we investigated the response of sucroses and gelling agents on the shoot organogenesis of the indigo plant. Micropropagation in terms of shoot regeneration and its growth was highly responded to sucrose and gelling agents. While culturing of internode explants on initial shoot regeneration media supplemented with sucrose and gelling agents of phytagar and gelrite significantly upgraded the regeneration efficiency as well as shoot growth. The regeneration capacity of the shoot was augmented with increased levels of sucrose up to 40 g L-1 and then started to decrease, whereas the increasing pattern continued even at the highest concentration (50 g L-1). The highest shoot regeneration (6.0 ± 0.5) was achieved by the treatment of 40 g L-1 giving 7.5 times higher shoot regeneration compared to the control. The increasing pattern for shoot length was more pronounced than that of shoot regeneration. The shoot length ranged from 10.2 mm to 23.5 mm within the sucrose treatments. In this study, the highest shoot length (23.5± 0.21) was observed by the treatment of 50 g L-1 exhibiting 2.3 times higher shoot length compared to the control. Gelling agent gelrite performed better than phytagar for both regeneration and shoot length growth. The shoot regeneration among the phytagar treatments ranged from 3.8 to 6.0 shoots/explant whereas the shoot regeneration ranged from 6.6 to 7.2 among the gelrite treatments. The highest shoots/explant (7.2) and the longest shoot length (22.4 mm) were observed due to the treatment of gelrite 3. The lowest shoot regeneration and shoot length were denoted when phytagar 9 was applied. It is proposed from our study that sucrose and gelling agent especially gelrite 3 could be applied in shoot organogenesis and plant transformation of any plant species, especially for P. tinctorium.
Determining Security Factors for Digital Infrastructure in the Financial and Banking Sector: Singapore's Approach
Authors: Gorian Ella
Published: November 2022

The object of the study is the relations in the field of ensuring the security of digital infrastructures in the financial and banking sector. The subject of the study is represented by regulatory legal acts and sources of "soft law" of Singapore, which establish requirements for information systems, personal and confidential data. The features of the Singapore approach to the regulation of relations in this area are determined. The requirements of the Monetary Authority of Singapore for the security of digital infrastructures in both the public and private sectors are considered. The features of ensuring the security of key components of digital infrastructures are characterized: digital identity; authorization and consent; functional compatibility of payment systems and data exchange. The role of the financial regulator in ensuring the security of digital infrastructures is investigated. Singapore has identified a holistic approach to the development of regulatory policy as the main security factors of the digital infrastructure of the financial and banking sector, as well as the determining role of the financial regulator in the creation of digital infrastructure. The technical side is just one of the elements of the digital infrastructure: it is necessary to balance regulatory, technical and business standards. The key components of the digital infrastructure allocated by the Monetary Authority of Singapore determine the level of security of the production processes of financial institutions. Attention should be focused on building the trust of the end user. The protection of the digital infrastructure of financial institutions from threats increases the degree of confidence in these institutions on the part of investors. Therefore, Singapore's financial institutions have a high investment attractiveness.
Features of the Psychographic Portrait of the Residents with Criminal Record living in Northern Territories and the Arctic Zone of the Khanty-Mansi Autonomous Okrug-Yugra and Yamalo-Nenets Autonomous Okrug

Published: November 2022

The psychographic features of the personality of residents of various regions of the Russian Federation are an interesting and insufficiently studied phenomenon from the standpoint of psychological knowledge. In our opinion, it is convenient to present such a phenomenon in the framework of personality research in the form of a psychological portrait - a kind of model structure reflecting the psychological characteristics of the object of research. The subject of the study is the elements of the psychological portrait of the personality of the studied contingent, the features of which constitute the content of the model of the psychographic portrait of the inhabitants of the northern territories. The parameters and model characteristics of the personality of the studied sample of residents of the region may be of interest to a wide range of very different practices – pedagogical, managerial, legal, professional and others. Separate, compositional parameters of model characteristics are presented in the study, which will form the basis of a general psychographic model of the personality of residents of the northern regions of Khma-Yugra and YANAO who have experience of illegal behavior. Such research is relevant and oriented in the practice of pedagogical, legal work with the population of the marked regions. If possible, a similar practice of scientific research on the presented topic can be transferred to other regions of the North and the Arctic zone of the Russian Federation. The solution of this task is a systematic part of the research project of the Russian Academy of Sciences under the general title "Experience in the application of customary law, history and humanization of penitentiary institutions of Ugra within the framework of European and Russian traditions (late XVI - early XXI centuries)". The research is of practical importance and its results, we hope, will be in demand by specialists from a wide range of various social practices. The main, generalized conclusion of the study is statistically confirmed personality traits of the studied contingent, reflecting the model characteristics of their originality regarding illegal behavior.
Los tratadistas del eros y la Academia. El caso de la Enciclopedia del erotismo de Camilo José Cela
Authors:   Constantine the Philosopher University in Nitra (Eslovaquia), Lampis Mirko
Published: November 2022

"This paper studies, both quantitatively and qualitatively, the treatment that Camilo José Cela provides, in his monumental Enciclopedia del erotismo, to the definitions of RAE’s Dictionary of Spanish (Diccionario de la lengua española), paying particular attention to the citation strategies of academic definitions and to those specific cases in which Cela explicitly corrects or criticizes them. Quantitatively, the importance of the definitions of the DLE in structuring the Enciclopedia entries is evident. Qualitatively, Cela’s reflections and amendments and his ideological criticism to the notions related to Catholic-bourgeois sexual morality show the controversy against the excessive «decency» of the Academy, which turns into defining inaccuracies and unnecessary moralizing evaluations."
El vosotrismo o vosotreo del habla canaria: causas y consecuencias
Authors:   Instituto Universitario de Lingüística Andrés Bello. Universidad de La Laguna (España), Morera Marcial
Published: November 2022

"There is not and there has never been, in the Spanish pronominal system, a more unstable field than that of second person plural forms. This grammatical subsystem has unceasingly evolved since the origins of the language. It has been conditioned by the need to renovate the forms of treatment of respect towards the listener. Social use inevitably degrades these formulas as the use of courtesy forms is generalized. This article aims to describe and explain, both semantically and socially, the heterogeneous situations that the use of this system (in particular, the form vosotros) presents in the current Canarian society. These situations point out to more or less ingenious solutions, like the conversion of the classic form of familiar treatment vosotros into a formula of respect whose future is quite uncertain, due to the pressure exerted by the most educated Canarian speakers and by the rules of the standard language."
La ausencia en Schiller: el deus absconditus y el ejecutor (Wallenstein y Wilhelm Tell)
Authors:   Universidad Autónoma de Madrid (España), Salmerón Infante Miguel
Published: November 2022

"The connection between Schiller’s dramas and the reflections developed in his philosophical and historical writings are a highly problematic question. Simplifying, it can be said that the philosophical texts project Schillerian ideals and the historical ones reflect his psychological knowledge of human beings. This tension between the ideal and reality is manifested, among other constellations, in that of absence. In Wallenstein and Wilhelm Tell, the leads are out of action for much of the plot. The character of Wallenstein is absent as a deus absconditus that will be revealed to have failed, whereas the character of Tell as an executor who leaves the collective of his people exempt from with guilt."

Published: November 2022

Communication is considered to be one of the central concepts in nursing and a prominent part of practising this profession. This study aimed to investigate the relationship between communication skills, mental health and self-esteem among nursing students at Hamadan University of Medical Sciences in Hamadan, Iran. A cross-sectional correlational study was conducted in 2018 on 320 undergraduate nursing students who were selected using a stratified random sampling method. The data was gathered using three self-administered questionnaires, namely, the Queendom Communication Skills Test, the Goldberg Mental Health Questionnaire-28 (GHQ-28), and the Coopersmith Self-Esteem Inventory. The data was analysed using R.V4.0.2. Using the elastic net method, mental health, self-esteem and age were shown to be associated with communication skills over 1 000 repetitions of the model. Communication skills were significantly associated with the three subscales of mental health (p < 0.001), self-esteem (p < 0.01), and age (p < 0.05). Regarding the significant relationship between communication skills, mental health and self-esteem of nursing students, it is recommended to organise self-esteem building and focus on mental health promotion to promote communication skills among nursing students.
Isaac Babel’s Short Story “Di Grasso”: Sources of the Plot and Problems of Commenting
Authors:   Gorky Institute of World Literature RAS, Moscow, Pogorelskaya E. I.
Published: November 2022

The article is devoted to the publishing problems of I. Babel’s short story “Di Grasso”, namely historical, literary and real commentary on this work. It turns out which events served as a source for both the entire story and its central episode — the performance of the Sicilian tragedian and his troupe on the stage of the City Theater in Odessa. Newspaper reports and testimonies of contemporaries are given, in which descriptions of the seemingly fantastic the-atrical technique used by Giovanni Grasso in this play. “Di Grasso” can be attributed to the writer’s conditionally autobiographical stories about childhood. Like the hero-narrator of the story, Babel was 14 years old during Giovanni Grasso’s tour in Odessa. Pages from his notebook of this period have been preserved, where he recorded, among other things, infor-mation about theatrical performances that he attended. On December 1, 1908, young Babel at-tended the play “The Curse” based on the play by Luigi Capuana, on December 5 - at the play “Civil Death” by Paolo Giacometti (“The Family of a Criminal” translated into Russian by A. N. Ostrovsky). The di Grasso jump depicted in the story is based on a scene from the play “Feudalism” based on the play “Valley” by Angel Guimera. However, in general, the plot of Babel’s play does not coincide with “Feudalism”. Having also partly used the plot of the “Curse” and, possibly, the “Rural Honor” of Giovanni Verga, everything else, except for jumping and “snacking” the opponent’s throat, the writer, most likely, just came up with. The story gives a review of the newspaper “Odessa News” about Grasso as the most amazing actor of the century. December 2, 1908 “Odessa News”, covering the tour of the Italian troupe, published a report on the first performance of “The Curse”, which really contained a very high assessment of Grasso’s performance. The touring repertoire of Italians in Odessa does not coincide with the one named in Babel’s story: “King Lear” and “Othello” by Shake¬speare, “Civil Death” by Giacometti and “Freeloader” by Turgenev. Of those listed in Grasso’s repertoire, there were only “Othello” and “Civil Death”, but “Othello” was not performed in Odessa. Thanks to the publications in the newspaper “Odessa Leaf”, the per¬formances performed in Odessa are known: “The Curse” (December 1), “Feudalism” (December 2), “An Eye for an Eye” (December 3), “Civil Death” (December 5).
The application of the Glasgow prognostic score to predict the survival in patients with metastatic pancreatic carcinoma
Authors: Mohammed Amrallah A. , Al-Zahrani Omar , Elsayed Fifi Mostafa
Published: November 2022

Objectives:

Thither is a more pressing effort to think about chemotherapy (CTx) in second-line and beyond in patients with metastatic pancreatic cancer (mPC). The current work aimed to evaluate the value of the Glasgow prognostic score (GPS) and modified Glasgow prognostic score (mGPS) to predict the survival in patients receiving second-line CTx protocol.

Material and Methods:

We retrospectively reviewed the patients’ medical files with mPC who received second-line CTx protocol between September 2013 and December 2017. The GPS/mGPS graded from 0 to 2 based on C-reactive protein and serum albumin.

Results:

One hundred and sixty-nine patients with mPC were eligible. Survival of patients with Score 0 (GPS/mGPS) was better than that of Score 1 (GPS/mGPS) or Score 2 (GPS/mGPS), which was statistically significant (P < 0.001). Of 78 patients who died, only 16 patients belonged to Score 0 (GPS/mGPS), compared to 30 patients belonged to Score 1 (GPS/mGPS) and 32 patients belonged to Score 2 (GPS/mGPS). Univariate analysis showed that high GPS/mGPS (P < 0.000) as well as poor Eastern Cooperative Oncology Group Performance Status (P < 0.000) and metastasis either to the liver (P < 0.01) or lung (P < 0.04) were linked with worse prognosis. A statistically significant association was detected between the two scores. Cohen’s Kappa coefficient (k) was 0.9, SD = 0.03; 95% CI (0.787–0.922; P < 0.001).

Conclusion:

Our data suggested that GPS/mGPS is an easy and applicable index that may be used in daily practice and may help in the prognostic stratification of mPC patients to avert overtreatment in frail patients and raise the best supportive treatment concept.

Time-reversal equivariant neural network potential and Hamiltonian for magnetic materials
Authors: Yu Hongyu , Zhong Yang , Ji Junyi , Gong Xingao , Xiang Hongjun
Published: November 2022

This work presents Time-reversal Equivariant Neural Network (TENN) framework. With TENN, the time-reversal symmetry is considered in the equivariant neural network (ENN), which generalizes the ENN to consider physical quantities related to time-reversal symmetry such as spin and velocity of atoms. TENN-e3, as the time-reversal-extension of E(3) equivariant neural network, is developed to keep the Time-reversal E(3) equivariant with consideration of whether to include the spin-orbit effect for both collinear and non-collinear magnetic moments situations for magnetic material. TENN-e3 can construct spin neural network potential and the Hamiltonian of magnetic material from ab-initio calculations. Time-reversal-E(3)-equivariant convolutions for interactions of spinor and geometric tensors are employed in TENN-e3. Compared to the popular ENN, TENN-e3 can describe the complex spin-lattice coupling with high accuracy and keep time-reversal symmetry which is not preserved in the existing E(3)-equivariant model. Also, the Hamiltonian of magnetic material with time-reversal symmetry can be built with TENN-e3. TENN paves a new way to spin-lattice dynamics simulations over long-time scales and electronic structure calculations of large-scale magnetic materials.
Mechanism of Nitrogen-Carbon Bond Formation From Iron(IV) Disilylhydrazido Intermediates During N2 Reduction
Authors: Bhutto Samuel , Hooper Reagan , Mercado Brandon , Holland Patrick
Published: November 2022

We recently reported a reaction sequence that activates C–H bonds in simple arenes as well as the N–N triple bond in N2, delivering the aryl group to N2 to form a new N–C bond. This enables the transformation of abundant feedstocks (arenes and N2) into N-containing organic compounds. The key N–C bond forming step occurs upon partial silylation of N2, which then can accept the aryl fragment. However, the pathway through which reduction, silylation, and migration occurred was unknown. Here we describe synthetic, structural, magnetic, spectroscopic, kinetic, and computational studies that elucidate the steps of this transformation. N2 must be silylated twice at the distal N atom before aryl migration can occur, and sequential silyl radical and silyl cation addition is a kinetically competent pathway to a formally iron(IV) intermediate with an NN(SiMe3)2 ligand. It can be isolated at low temperature. Kinetic studies show its first-order conversion to the migrated product, and DFT calculations indicate a concerted transition state for migration. The electronic structure of the formally iron(IV) intermediate is examined using DFT and CASSCF calculations, which reveal contributions from iron(II) and iron(III) resonance forms with oxidized NNSi2 ligands. The depletion of electron density from the Fe-coordinated N atom makes it electrophilic enough to accept the incoming aryl group.

Bioelectronics is a perspective future of electronics. The modelling of the protein is an important part that allows to search the appropriate folding structure with applicable conductivity properties. The classical computers struggle from modelling large structures because of number degrees of freedom. The mathematical modelling inside the quantum programming paradigm is a possible way to overcome this factor. This work describes a simplification algorithm of bio material (protein) model used in bioelectronics
MONITORING SYSTEM DESIGN IN HIGH PERFOMANCE COMPUTING CENTER FOR SOLVING MATERIAL SCIENCE PROBLEMS
Authors: Maminov A.
Published: November 2022

The paper considers methods for monitoring the workload of resources of a high-performance complex when setting computational problems of materials science in a common execution queue. Since materials science algorithms can be effectively run in parallel and are demanding on computing resources, there is a need to use supercomputer systems. However, inefficient use of resources significantly increases the estimated time of tasks. We propose to implement a monitoring system for subsequent analysis of allocated computing resources.

Authors: Ivanchenko G. , Ten A. , Butenko M. , Kuzmin N.
Published: November 2022

In this paper, the vibrational spectrum of diamane [1] is calculated within the framework of Hamilton's formalism. The geometric model of the diamane is represented as a two-layer graphene, but each C-atom has an sp3 hybridization of external electronic orbitals. The carbon atoms of one of the graphene sublattices are covalently bound to the atoms of the second graphene layer, and the outer hydrogen atoms are covalently attached to the atoms of the second sublattice. A diamane unit cell contains two carbon atoms and one hydrogen atom. When constructing the model, the deformation of the graphene plane as a result of the hydrogen atoms addition to it and the change in the hybridization of the external electronic orbitals of carbon atoms from sp2 to sp3 were taken into account. The interaction between hydrogen atoms was not taken into account.

CONDUCTIVITY OF AQUEOUS SOLUTIONS OF ALANINE AND VALINE PREPARED BY THE ITERATIVE DILUTION METHOD FOLLOWED BY INTENSIVE MECHANICAL IMPACT
Authors: Semenova E. , Lobyshev V.
Published: November 2022

The method of preparation of highly diluted solutions, by iterative dilution accompanied by intense mechanical action is described. The results of high-frequency electrical conductivity and dielectric permittivity of L and D isomers of alanine and valine are presented. The absence of dielectric increment in all samples indicates the absence of mesoparticles with high dielectric permittivity in solutions. A non-monotonic, complex dependence of electrical conductivity on the number of N dilution iterations is recorded. This type of dependence persists at large N, when the concept of the solute concentration loses its meaning, which indicates changes in the composition of aqueous solutions under mechanical impact. Repeated measurements of samples stored in closed vials in closed cardboard boxes at room conditions revealed long-term evolutionary processes in aqueous solutions. The peculiarity of the evolution of the electrical conductivity of alanine and valine solutions, in comparison with the previously studied potentiated diclofenac solutions, consists in a decrease in electrical conductivity over time, which contradicts the additional dissolution of carbon dioxide from the atmosphere when opening vials and dissolving glass. There were no differences in the properties of L and D isomers of alanine and valine solutions.
