Science and religion in the writings of Roger Bacon
Authors: Ivanov A. V.
Published: October 2024

The article analyzes the views of the outstanding medieval thinker R. Bacon on the relationship between science and religion. The originality of his solution to the problem of authorities in these most important spheres of spiritual culture is shown, as well as the importance of the separation of external and internal experience introduced by him. The thoughts of the English philosopher about the irreducible connection between science and religion and the need to consider them as developing types of knowledge also sound very modern. All this forces us to recognize the ideological legacy of the "amazing doctor" as an actual subject not only of historical-philosophical and historical-scientific, but also of theoretical research.

The article considers the phenomenon of determining religious conversion on the basis of sociological studies of social processes and religiosity in modern Kazakh society. Its cause-and-effect relationships, evolution and dynamics of popularization are investigated. It is revealed that although there are other important non-causal types of connections, the principle of causality of religious transitions is its basis. The classification of the chains of causing religious conversion is presented and attempts to study it on the basis of some integral calculations are demonstrated. The analysis of the concept is carried out in order to apply it in practice to compile a mechanism for political decisions in the field of spiritual tolerance of society in the conditions of its economic development. The political science of the obtained data of the study of religious conversion allows us to identify positive and negative determinations of the spirituality of Kazakhstanis. The demonstrated study of the urgent social problem for Kazakhstan is relevant for all countries of the post-Soviet space.

The article discusses the courses on the “History of Christian art” taught by Dmitry V. Aynalov and Alexey M. Mironov from 1893 to 1917 at the Kazan Imperial University. Practical interest for the modern educational process is the concept of course programs, the actual material and methodology of its presentation, methods of interpretation of sources. The article claims that Mironov and Aynalov independently developed training courses on the “History of Christian art”. Originality of the concept of am Mironov's idea is that during the course he addressed new topics for that time: the history of Western European miniatures and Christian mosaics, decorative and applied art, and Gothic. The article proposes to implement a project to reissue the course of Mironov. The project will help introduce a little-known part of the scientist's didactic heritage into scientific circulation, which is of interest not only for historians of science and education, but also for cultural, religious and art historians. The publication of the courses will help to correct the existing stereotypes in historiography in relation to different scales and the degree of recognition in the academic community of Russian art historians - Dmitry V.

Authors: Lekarenko O. G.
Published: October 2024

Donald Trump's policy, which considered American national interests more significant than global governance, caused a deep crisis in relations between the European Union (EU) and the United States. After Joe Biden's victory in the US presidential elections, a united Europe received a good chance to "reset" transatlantic relations. Based on the official documents of the EU and the US, the article analyzes the efforts of both sides to restore the American-European partnership from the election of Joe Biden as the US President (November 2020) to the EU-US summit in Brussels (June 2021). The author briefly outlines the problems that have arisen in the EU-US relations during the presidency of Donald Trump. Then the proposals of the EU to renew the EU-US agenda for global change are analyzed. At the same time, the Biden government has set a goal to revise Trump's foreign policy legacy, restore American leadership in transatlantic relations, and strengthen relations with the closest allies and partners. The United States has returned to some international agreements that are meaningful for the EU. The United States and the European Union took a number of measures to mitigate trade conflicts between them. In June 2021, the EU-US summit adopted a joint statement “Towards a Renewed Transatlantic Partnership”, the EU-US Council on Trade and Technology was established. The EU and the US agreed to cooperate in order to end the coronavirus pandemic and ensure a sustainable global economic recovery; to protect the planet from environmental disaster; to contribute to the strengthening of trade, investment and technological cooperation; to build a more democratic and secure world. In the conclusion, the author highlights that warming in the EU-US relations could facilitate further interaction between transatlantic partners.

Authors: Tataurov S.F.
Published: October 2024

Providing the population of the Russian Siberian town in the 17th-18th centuries with wooden tableware and its assortment is still an unexplored area of everyday culture of Siberians. The preservation of wood in the cultural layers of archaeological monuments of this time does not allow recreating completely the set of wooden dishes and utensils used by the local population. In addition to finds from Mangazeya, Nadym and Yakut ostrogs, where the harsh climate turned out to be a good preservative for wood. The nature of the functioning of northern towns does not allow us to directly extrapolate these materials for the population of the more southern latitudes of Western Siberia, but provides an opportunity for comparative analysis with our materials. The peculiarities of the cultural layer of Tara which preserves organic materials well have allowed us to collect a representative collection of objects over the years of excavations. This made it possible to recreate the entire set of kitchen utensils for cooking and table setting for the residents of this town. The purpose of our research is to introduce into scientific circulation a collection of wooden dishes and utensils from the excavations of Tara and analyze its place in the everyday culture of the inhabitants of Tara
Prisoners of War in Olonets Province at the End of World War I: the Problem of Naturalization and Repatriation
Authors: Krivonozhenko A.F.
Published: October 2024

There were many German and Austro-Hungarian prisoners of war in the Olonets province during the World War I. Their appearance here related to the construction of the Murmansk railway. In addition, local factories needed labor. The conditions of the prisoners' existence in the northern province were extremely difficult. The transition to Russian citizenship was regarded as one of the ways to improve their situation. However, the tsarist government systematically refused the prisoners their petitions. The policy of the Russian Provisional Government in this matter has not changed either. The Bolsheviks allowed the free transfer of prisoners to Russian citizenship but the war on the Eastern Front had already ended by that time. It was established a connection between the problem of transition to Russian citizenship and the problem of repatriation. Archival materials allow us to study this connection. A lot of prisoners sought to become Russian citizens in the summer of 1918 to avoid being sent to Germany and Austria-Hungary. There they were threatened with being re-sent to the front. As the result of the study, it was found that the process of repatriation of prisoners of war from the Olonets province had its own characteristics. They were caused by internal and external factors. The internal factor was a serious food crisis in the province. The external factor related to the intervention of the Entente troops from the Kola Peninsula. It could lead to the capture of German and Austro-Hungarian prisoners of war in the Olonets province. These factors led to the organization of the rapid repatriation of prisoners of war from the region.

Study on the relationship between corporate overinvestment and management incentives—An analysis from the perspective of different ownership structures
Authors: Yu Zixuan
Published: October 2024

This paper aims to explore the relationship between corporate overinvestment and management incentives, focusing particularly on the influence of different ownership structures. Utilizing agency theory and ownership structure theory, this study constructs a theoretical framework and posits hypotheses on how management incentives might influence corporate overinvestment behaviors under different ownership structures. Listed companies from 2010 to 2020 were selected as the research sample, and the hypotheses were empirically tested using descriptive statistics, correlation analysis, and regression analysis. The findings suggest that a relatively concentrated ownership structure may encourage management to adopt more cautious investment strategies, thus reducing overinvestment behaviors; while under a dispersed ownership structure, the relationship between management incentives and overinvestment is more complex. This study provides new evidence on how management incentive mechanisms influence corporate decision-making in different ownership environments, offering significant theoretical and practical implications for improving internal control and incentive mechanisms.

Authors: Kamiński Kamil , Grudzień Joanna , Kaczor-Kamińska Marta
Published: October 2024

Gel electrophoresis is one of the most important and most widely used tools in biomedical sciences. However, when students are acquainted with these techniques, information related to practical applications often neglects the physicochemical foundations of the occurring phenomena. The following article proposes a laboratory exercises scenario conducted in the problem-solving and decision-making strategies, which aims to familiarize beginner students with the physicochemical basis of electrophoresis in a simple and accessible way. By analyzing the scheme presented, students will gain knowledge of the basic sciences, as they will learn about the advantages and limitations of the method in addition to its applications. The experiments are designed in a way that allows students to draw conclusions about the parameters affecting the electrophoresis process and the sources of obvious errors. Moreover, the use of simple ionic dyes eliminates the need for complex apparatus and toxic reagents, which may be harmful. The main outcome of the class is to develop students’ skill to design their own simple experiments using this commonly used technique.

Published: October 2024

This article presents an innovative method for predicting transformer temperature and faults in distribution substations using a digital twin model combined with deep learning techniques. By constructing a digital model of the transformer, real-time monitoring and precise simulation of its operating status are achieved. In the prediction process, convolutional neural networks (CNN) and long short-term memory networks (LSTM) are fused to mine data features deeply and predict the future state of the transformer. The results show that this method demonstrates significant advantages in transformer temperature and fault prediction, with an accuracy rate as high as 96.55%. Moreover, the error rate of this method has been significantly reduced through comparative experimental verification. In addition to ensuring high accuracy, this method achieves a false alarm rate of less than 0.12% and an average detection time of only 1.35 seconds, further highlighting its effectiveness in practical applications. Therefore, the transformer temperature and fault prediction system developed in this article for distribution substations can effectively improve the stability and safety of the electrical power system (EPS) and provide new and powerful support for the intelligent management and maintenance of transformers.
Testing the diagnostic accuracy of a 68Ga-PSMA PET Scan in Early Biochemical Recurrence of Prostate Cancer
Authors: Vigna-Taglianti Riccardo , Boriano Alberto , Martini Stefania , Olivero Francesco , Solla Salvatore , Spinelli Lavinia , Gianello Luca , Peano Simona , Merlotti Anna Maria
Published: October 2024

Background

PET-PSMA is currently used for restaging prostate cancer (pCa) after primary surgery or radiotherapy. The PSA levels beyond which it is useful to perform it, in terms of cost-benefit ratio, are not to date clearly defined.

Patients and Methods

70 patients with biochemical recurrence of pCa after surgery or radiotherapy were evaluated with PET before starting salvage radiotherapy (SRT); the correlation between biochemical response and the findings of the pre-treatment PET was evaluated. The ability of SRT to kill cancer cells and lower PSA levels was used to assess the real presence or absence of disease in the irradiated sites.

Results

The mean pre-RT PSA value differs significantly between PET+e and PET-patients (1.04 ng/mL vs 0.47 ng/mL, p<0.001). After radiotherapy, the mean PSA value decreased significantly in the whole group (mean 0.8 ng/mL pre-SRT vs 0.1 ng/mL post-SRT, p < 0.001). Sensitivity and accuracy were 78% and 76% respectively. For the patients irradiated on the prostatic fossa sensitivity and accuracy of PET scan were both 72% and in the subgroup of irradiated on the prostatic fossa with a PSA value ≤ 1 ng/mL sensitivity and accuracy were both 62%. For PSA values between 0.2 to 1 ng/mL the PET sensitivity decreases from 72 % to 62%, with a probability of a false negative test of 40%.

Conclusions

To optimize the cost-benefit ratio, these results suggest caution in the evaluation of negative PSMA PET results in biochemical relapsed patients with a PSA value less than 0.5 ng/mL.

Authors: AKSENT'EV Andrei A.
Published: October 2024

Subject. This article discusses the theoretical, historical and methodological particularities of State assistance accounting, including the socio-economic relations that have developed between companies, developers of accounting standards and the academic community.
Objectives. The article aims to critically characterize approaches to State assistance accounting, show the theoretical inconsistency of the International Financial Reporting Standard (IAS) 20 – Accounting for Government Grants and Disclosure of Government Assistance, and choose the most appropriate method that corresponds to the guideline scientific concepts.
Methods. The research is speculative. For the study, I used the dialectical method of scientific knowledge, the method of collecting theoretical and regulatory information, the method of formalization, as well as analysis, synthesis, observation, and comparison.
Results. The scientific novelty lies in the generalization and characterization of five approaches to the accounting for State assistance. The article substantiates that State assistance should be recognized as part of liabilities if and only if there are current and/or future conditions that impose obligations on the organization to receive State assistance, otherwise it should be recognized exclusively as part of equity. It is found that the background of these standards in the area of accounting for State assistance is the result of lobbying companies to increase net income.
Conclusions and Relevance. The results of the study call into question the acceptability of the theoretical foundation of IAS 20. The results of the study are primarily intended for the accounting scientific community and developers of accounting standards.
