Memories of Boris Pavlovich Orlov
Authors:   Siberian Institute of Management – the branch of the Russian Presidential Academy of National Economy and Public Administration, Novosibirsk, Khanin Grigory
Published: October 2022

Memories of Novosibirsk economist Boris Pavlovich Orlov consist of three episodes. The first analyzes his work “Development of Transport in the USSR”. The author analyzes the fundamental nature of the work, the use of archival data and the truthfulness of the analysis. An objective coverage of the history of Soviet transport is noted, especially during the periods of the first five-year plan and the Soviet-Finnish war. The author gives a qualified analysis of the reasons for the orientation in railway transport towards the development of track facilities and the expansion and renewal of rolling stock instead of new railway construction. The second episode is connected with the defense of Ph.D. thesis of the author, in which Boris Pavlovich was the first opponent. Despite the seditiousness of many of its provisions for that time, Orlov supported it and highly appreciated it. The third episode is connected with the author’s leadership of the student scientific society at the Faculty of Economics of the Novosibirsk State University, of which Orlov was then the dean. The scientific work of this society, which boldly explored the acute problems of the socialist economy, was subjected to political persecution. Boris Pavlovich did not take any part in this company, at the risk of his administrative position. In conclusion, the high level of Boris Pavlovich Orlov’s qualifications, his honesty, civic courage and decency are discussed in the article.
Method of estimating the market cost of art objects based on the interpolation model
Authors: Maltsev Mikhail , Baglyuk Sergey , Solntseva Irina
Published: October 2022

The task of assessing the market cost of an art object (AO) is relevant for artists, art dealers, collectors and museum workers, among others. Experts and appraisers who need appropriate automation tools are involved in its solution. The task is complicated by the inconsistency of the conceptual apparatus of the specialists’ various fields of knowledge, the specifics of AO and the art market. Known methods for solving it, especially automated methods, are not numerous and not universal. The purpose of this study was to develop a method for automated valuation of the market value of AO, which defines it as the sum of two components: the prime cost of the AO and added cost – the cost of the asset “value of the AO.” To calculate the first component, a cost–based approach and an additive model were used; the second was a comparative approach and an interpolation model. The added value of modern AO is represented by a function of the parameters of each of the four price-forming factors of AO: “the value of the artist,” “the artistic value of AO,” “the cultural value of AO,” “the quality of the state of AO.” It is proposed to implement models in the form of a software package integrated into the information systems of modern art institutions, having coordinated the data formats used.
Quality of strategic management under ambiguity: Assessment within the framework of sustainable development
Authors: Myznikova Mariya
Published: October 2022

Amidst a high and increasing level of ambiguity, the quality of strategic management when ensuring the achievement by an enterprise of a sustainable development trajectory becomes particularly important. The issues of formation and efficient implementation of the strategic management mechanism bring into focus the task of finding tools for assessing the quality of strategic management. Meanwhile, the agenda of developing the tools to assess the quality of strategic management of an enterprise from the standpoint of achieving a sustainable development trajectory under ambiguity remains poorly understood. In this regard, the purpose of this study is to improve the quality of strategic management of industrial enterprises operating under uncertainty by developing and testing on the example of individual enterprises of the Donetsk region a toolkit for assessing the quality of strategic management in the context of an enterprise achieving a sustainable development trajectory. To reach this goal, this study uses a synthesis of systemic, cybernetic and synergetic approaches. For this purpose, within the framework of the study, a conceptualization of the main notions was carried out and theoretical and methodological approaches to the interpretation of the notions of “strategic management,” “sustainable development” and “strategic uncertainty” were proposed. Based on the author’s approaches to the interpretation of the main notions, it was suggested to assess the quality of strategic management in terms of the goal of such management, which is to achieve a sustainable development trajectory. Using the author’s approach, an assessment was made of the quality of strategic management of industrial enterprises in the Donetsk region in the context of their achievement of sustainable development. Approbation of the proposed tools led to the conclusion that the integral assessment indicator for all analyzed enterprises did not have an unambiguous and unidirectional downward trend. The foregoing indicates the absence of a stable trend towards the attractor for the analyzed period for all the enterprises in question, which makes highly topical the search for reserves to increase the efficiency of strategic management of industrial enterprises in the Donetsk region, which constitute the prospect for further research.

Authors: Wijaya Tony
Published: October 2022

Game-oriented business development is growing quickly and this encourages the digital economy in Indonesia. This research aims to examine the role of perceived value on the purchase behavior of online game attributes in Indonesia based on gender groups. Samples were taken from several online gaming communities in Indonesia. The variables in this study consist of perceived value variables, namely emotional, quality, social and economic value, which are antecedents for the online game attribute purchase intention and purchase behavior variables. Data were analyzed using Structural Equation Modeling. The research results show an influence on purchase intentions of perceived value which consists of emotional, quality, social and economic value and ultimately shapes the buying behavior of online game product attributes. There is a difference in each component of perceived value on purchase intention between male and female groups. Emotional and quality values do not affect the female group’s pursuit intent, while social values do not significantly affect the male group.
The Relationship between Native and Foreign Language Speaking Proficiency in University Students
Authors: Stankova Eva , Chlumska Renata , Zerzanova Dana
Published: October 2022

Background. There are many factors that affect the development of speaking in a foreign language. Drawing on the theories that state that competencies established in a native language will transfer across foreign languages, this study examines whether there is a relationship between native and foreign language speaking proficiency.

Purpose. Although literature research indicates that native and foreign language acquisition processes are interrelated, there is a lack of studies comparing proficiency levels of native and foreign language speaking skills in adult learners. The purpose of this study was to examine the relationship between speaking competences in English as a Foreign Language and Czech as a Native Language in university students. 

Methods. A between-group design was used to compare two groups of fifty university students at two different levels of their speaking proficiency in English. Both groups were tested in speaking in Czech. Each test was assessed by an analytical rating scale examining four speaking sub-skills: accuracy, discourse, content and paralinguistics. The scores were analyzed using the F-Test for Equality of Variances and T-Test for the Differences between the Means.

Results. The results showed that the group with the lower level of speaking proficiency in English achieved significantly worse scores for their speaking sub-skills in Czech than the group with the higher level of speaking proficiency in English.

Implications. The study offers another piece of empirical evidence in support of the theories that state that competencies established in a native language will transfer across foreign languages and suggests the importance of the development of native language competence with regard to later proficiency in a foreign language.
Relationships Between Language-Related Variations in Text Tasks, Reading Comprehension, and Students’ Motivation and Emotions: A Systematic Review
Authors: Wirth Lina , Kuhl Poldi , Ehmke Timo
Published: October 2022

Background. There is consensus in research that students' motivation and emotions are important for learning and achievement processes in the educational context, as are language competencies that, related to the demands of academic language, enable participation in education. However, the interrelationships between these aspects have hardly been empirically investigated in depth.

Purpose and Methods. This systematic review addresses this research need, and aims to synthesise the existing evidence on the interrelationship between motivational/emotional and language-related variables. First, the relationship between learners’ motivation and emotions, and their language competencies is considered. Second, findings on how motivation and emotion depend on language-related factors are compiled.

Results. A systematic data search conducted for this purpose yields seven studies. Five studies relate to the first concern, and confirm the effects of motivational and emotional variables on reading comprehension. Emotions, in particular, emerge as strong predictors. Two studies relate to the second concern, and report significant effects of language-related variations in text tasks on students’ motivation; however, neither study considers emotions.

Implications. The findings are used to derive implications for language design in the educational context and identify important research gaps.
Radyal akışlı francis su türbinlerinin kanatçık profilinin belirlenmesi ve performans analizi için bir matematik modelin geliştirilmesi
Authors: ÖZDEMİR Abdullah Onur , KARABULUT Halit
Published: October 2022

Turbo makinelerin rotor kanatçıklarının tasarımında Euler’in turbo makinelerin moment ve güç hesabı için türettiği eşitlik kullanılmaktadır. Bu eşitlik ile sadece rotor kanatçıklarının giriş ve çıkış açıları belirlenebilmekte, kanatçıkların tam profili belirlenememektedir. Kanatçıkların arasındaki rölatif akışın yerel hız ve yerel ivmesinin belirlenmesi için kanatçıkların tam profilinin bilinmesi gerekmektedir. Bu çalışmada, içten dışa radyal akışlı su türbini çarkının momentini belirlemede kullanılmak üzere bir matematik model geliştirilmiştir. Geliştirilen modelde türbin kanatçıklarının profili silindirik koordinat sistemine göre matematiksel olarak tanımlanmakta ve kanatçıklar arasından geçmekte olan akışkan zerrelerinin yerel hız ve ivme dağılımları hesaplanmaktadır. Hesaplanan hız dağılımı kanatçıkların giriş ve çıkışındaki hız üçgenlerinin oluşturulmasına ve Euler türbin teorisi yardımı ile çarka etkiyen harici moment ve gücün hesaplanmasına imkân vermektedir. Ayrıca, geliştirilen model kullanılarak, çark üzerinde oluşturulan hacim elemanlarına etkiyen atalet kuvvetleri ve bu kuvvetlerin çark eksenine göre oluşturduğu momentler tanımlanmakta, sonra integral hesap ile çarka etkiyen toplam moment ve güç hesaplanmaktadır. İntegral hesaptan elde edilen moment bağıntısı sürekli çalışma şartlarında Euler türbin teorisinden elde edilen moment bağıntısına dönüşmektedir. Geliştirilen moment denklemi kullanılarak 10 m3/s civarında debiye ve 100-200 m aralığında düşüye sahip olan bir su kaynağı için türbin çarkının analizleri yapılmıştır. Kanatçık profilinin ivme ve dolayısıyla çarkın performansı üzerinde etkili olduğu tesit edilmiştir.

Prospects for the use of statins in the treatment of neurofibromatosis type 1
Authors: Mustafin R. N.
Published: October 2022

Neurofibromatosis type 1 is caused by a germline mutation in the NF1 gene encoding the tumor suppressor neurofibromin. Deficiency of this protein causes hyperactivation of Ras proto-oncogenes. This leads to the development of tumors. Ras proteins undergo prenylation, which is inhibited by inhibitors of 3-hydroxy-3-methylglutaryl-coenzyme-A reductase. Therefore, statins can be proposed as anticancer drugs in the complex treatment of neurofibromatosis type 1. Clinical studies have proven the effectiveness of statins in the treatment of sporadic malignant neoplasms, in the pathogenesis of which mutations in the NF1 gene play an important role. Various pathways of the influence of these drugs on the development of tumors are described, including the activation of autophagy, ferroptosis, suppression of proliferation, stimulation of antitumor immunity, and effects on the microenvironment of neoplasms. Data on the effect of statins on the development and progression of neurofibromas in patients with neurofibromatosis type 1 are not presented in the scientific literature. However, it was found that statins enhance the effect of anticancer drugs, the use of which in monotherapy against malignant neoplasms associated with neurofibromatosis is ineffective. In this regard, despite the inefficiency of statins in cognitive disorders in patients with neurofibromatosis type 1, the introduction of these drugs into clinical practice in combination with other drugs could provide a pleiotropic effect, affect various links in the pathogenesis of the disease.

Introduction. The recurrence of diffuse large B-cell cell lymphoma in the central nervous system in the vast majority of cases is a fatal manifestation of the disease. The study of the lymphoma mutational profile can improve the accuracy of the prognosis of relapse in the central nervous system and justify the selection of patients for preventive treatment. Aim. To evaluate the mutational profile of cases of diffuse large B-cell cell lymphoma with central nervous system damage in relapse based on the results of our own experiment on high-performance sequencing.

Materials and methods. On the Illumina platform, full-exome sequencing of diagnostic samples of diffuse large B-cell cell lymphoma with relapses in the central nervous system was performed. A panel including more than 70 genes was analyzed.

Results. Four main groups of genetic events can be distinguished in the group of studied samples, namely: combined mutations in the NF-kB (MYD88, NOTCH1, CD79B, CARD11) and JAK-STAT (PIM1, STAT6) signaling pathways, as well as aberrations in the main oncosuppressor TP53 and chromatin remodeling system genes (ARID1A, KMT2D, EP300, SMARCA4). A recurrent mutation c. 794T>C, p.L265P MYD88 was detected in the study group. Among other findings, mutations in the CIITA and CD58 genes should be noted, which are important in avoiding tumor cells from immune surveillance.

Conclusion. Despite the apparent heterogeneity of the mutational profile of diffuse large B-cell cell lymphoma with relapses in the central nervous system, in most cases, tumor cells were characterized by genetic disorders leading to the production of a large number of pro-inflammatory cytokines by malignant lymphocytes, as well as aberrations that reduce immunogenicity and contribute to the avoidance of immune surveillance by the tumor.
Classic Samarra Painted Pottery from Yarim Tepe I, the Neolithic of Northern Iraq
Authors: Petrova N. Y.
Published: October 2022

This study focuses on the Classic Samarra painted ware from the Standard Hassuna layer at Yarim Tepe I, in Northern Iraq. Two groups of imports are described. The first consists of Classic Samarra, apparently related to Central Mesopotamia; the second, of Samarra Ware imported from the west. It is hypothesized that the Samarra pottery was imported not only from the center to various parts of the periphery, but also from one part of the periphery to another. As a result of comparison of the ceramics, a hypothesis is proposed that Classic Samarra was formed based on a symbiosis of two earlier cultural groups: the Proto-Hassuna period in Northern Mesopotamia, and Neolithic traditions originating from Central Zagros.

Published: October 2022

We review the scholarship relating to the megalithic tradition of East and Southeast Asia and the results of its archaeological study. The major center of this tradition in East Asia is Korea, where it reveals considerable heterogeneity. In the Bronze Age, it is represented by dolmens and menhirs, and in the later periods by stone tombs, chambers, and pyramidal mounds. The latest megaliths are anthropomorphic statues of the Dolhareubang type, on Jeju Island off the southern tip of the Korean peninsula. Southeast Asian megaliths, which are described in detail, originate from similar structures in East and South Asia while being less known and less accurately dated, and revealing specific features of construction. Owing to the ethnographic sources on local peoples, Southeast Asian megaliths provide valuable data on their layout, function, and associated mythology. We demonstrate common features in megalithic traditions of East and Southeast Asia and their specificity in each region. Principal sources are described, and major trends in the study of megaliths in those territories are outlined. In sum, megaliths of East and Southeast Asia are an independent archaeological phenomenon requiring future studies.
Grave Goods of an Elite Saka Burial at Kyrykoba in the Context of Cultural Ties Between the Nomads of Kazakhstan and Siberia
Authors: Iskakov K. A. , Umitkaliev U. U. , Mitko O. A.
Published: October 2022

This article describes the findings of excavations of an Early Saka kurgan at Kyrykoba, Eastern Kazakhstan. The kurgan had been looted; human remains, according to physical anthropologists, belonged to a mature woman. Her cranium exhibited trepanation. Some 200 artifacts were found, mostly gold and stone ornaments (belt clips, gold seed beads, and simple beads). The most interesting find is a bimetallic pin made of iron. Its rod is missing; the tiny head, less the 1 cm in diameter, is covered with gold foil. On its surface, there is a figure of an ungulate with a curved antler, its body twisted 180°. This stylistic device in the depiction of ungulates and predators is typical of the Scythian-Siberian art of Kazakhstan and Western Siberia in 700–300 BC. Other rare finds include ornaments made from a cretaceous layer of oyster shells, such as pendants shaped as oval plates imitating tusks, or figurines of predatory animals— 20 pieces, ranging in size from 0.4 × 0.4 to 2.5 × 2.5 cm. Oyster shells with thick cretaceous layers had been procured from the coasts of the Indian Ocean and the Persian Gulf. The beads and the animal figurine made from cretaceous layers of oyster shells are paralleled by those from an Early Scythian era burial at Gilevo-10, Altai. These artifacts indicate regional and intracontinental trade and cultural ties in Eastern Kazakhstan and Western Siberia, evidenced by similar technological traditions, images, compositions, and decorative motifs.

AIM: To identify psychological factors of the risk of tobacco addiction among students of the European North of Russia.
MATERIAL AND METHODS: The study involved 137 students of Arkhangelsk state universities, comprising 37 men and 100 women aged from 17 to 25 years, preselected for a number of characteristics (born in Arkhangelsk or the Arkhangelsk region; raised in a full, socially prosperous family; without financial and household problems; without chronic somatic and neurological diseases). Identification and analysis of tobacco smoking experience were carried out by retrospective self-assessment of the subjects. The psychological status of the respondents was determined by assessing the indicators of the Freiburg multifactorial personality questionnaire (FPI); accentuations of temperament and character, suggestibility, frustration, irritability and resentment; adventurousness, behavioral, social, professional, economic, political activity, and social destructiveness. The WilcoxonMannWhitney method and Fishers F-criterion were used for statistical analyzes.
RESULTS: In the group of smoking men, high values of hyperthymia (Me=18 units), masculinity (Me=8 units), sociability (Me=9 units), behavioral activity (Me=7 units), and social activity (Me=7 units) were recorded. In the group of smoking women, high values of exaltation (Me=24 units), masculinity (Me=8 units), sociability (Me=9 units), and social activity (Me=7 units) were recorded.
CONCLUSION: This study reports, for the first time, the features of personality traits in smoking boys and girls permanently residing in the Northern territories of the Russian Federation. Psychological factors of the risk of tobacco addiction formation in boys and girls permanently residing in the Northern territories of the Russian Federation have been determined.

Published: October 2022

INTRODUCTION: The factors and mechanisms of progression and recurrence of the palmar fascial fibromatosis with formation of severe Dupuytrens contracture, remain insufficiently studied.
AIM: To identify probable mechanisms of progression of the palmar fascial fibromatosis based on the comparative analysis of clinical and morphological characteristics of patients with Dupuytrens contracture of different extent of severity.
MATERIALS AND METHODS: Objects: medical histories and histological preparations of surgical material of patients with III (group 1, n = 121) and IIIIV (group 2, n = 135) degree Dupuytrens contracture. Methods: clinical, histological, statistical.
RESULTS: Clinical markers of hereditary predisposition to Dupuytrens disease (the percentage of patients under 50 at the time of onset of the disease and the frequency of involvement of both hands) were comparable in the study groups. The incidence of diseases of the circulatory system was reliably higher in group 2: 57.0% against 41.3% (p 0.01). A prolonged course of the disease ( 8 years) was identified only in half of the patients of group 2. The median of the content of hyperplastic connective tissue in the palmar aponeurosis in patients of groups 1 and 2 was 22.9% and 11.3%, respectively (p 0.001), interquartile range 0%67.8% and 0%56.7%, respectively. In the capillary network and in the intima of larger vessels, CD34-positive endothelium was identified in patients of both groups. Around the blood vessels supplying fibromatous nodules and cords, cells expressing CD34 were found. Thickness of adventitia and Kernogan index in the arteries perforating the palmar aponeurosis, were higher in group 2.
CONCLUSION: A higher frequency of comorbid diseases of the circulatory system, more evident thickening of adventitia of arteries perforating the palmar aponeurosis, and reduction of their throughput capacity in patients with severe Dupuytrens contractures indicate the significance of systemic and regional vasogenic mechanisms of progression of the palmar fascial fibromatosis. The content of hyperplastic connective tissue (histological predictor of recurrence) varies individually with each degree of contracture.

Published: October 2022

INTRODUCTION: PNonspecific aortoarteritis is a rare autoimmune disease with the involvement and narrowing of the aorta and its branches leading to ischemia of the respective arterial region. In the territory of the Russian Federation, the most common manifestation of Takayasu nonspecific aortoarteritis is lesion of the branches of the aortic arch, which in rare cases leads to development of the so called bald arch syndrome. In response to hypoxia, intersystemic collaterals are formed through the neoangiogenesis or redirection of the blood flow from the occluded vessels to small-diameter vessels. In patients with bald arch syndrome, the key role in blood supply to the brain is played by the vertebral arteries. Here, collateral blood supply is realized through the intersystemic anastomoses, most often through the anastomotic leaks between the intercostal and internal thoracic arteries. In the literature, single cases of formation of collaterals between coronary and bronchial arteries are reported. The article presents a clinical case of coronary-vertebral anastomoses in a patient with extremely severe course of Takayasu arteritis with occlusion of the brachiocephalic trunk, right common carotid artery (CA), left common CA, right internal CA, left internal CA (bald arch syndrome). The probable cause of such course of the disease was late referral for medical help by the patient and lack of adequate basic therapy.
CONCLUSION: The demonstrated case is the fourth case in the world literature describing the existence of collaterals between the coronary arteries and cerebral arteries, and the first case in the world describing the existence of collaterals from the right and left coronary arteries to the vertebral artery. Such unusual pathway of collateral blood supply in the patient is explained by the absence of the possibility for collateral compensation from the systems of subclavian and intercostal arteries, severe chronic cerebral ischemia. Usually, the causes of angina pectoris in patients with nonspecific aortoarteritis are spread of arteritis to the coronary arteries, insufficiency of the aortic valve, hypertrophy of the left ventricle. In the described case, none of these conditions was present, and angina can only be attributed to the existence of unusual collaterals and the development of a transient steal syndrome.

Apical microleakage comparison using various sealers and different obturation techniques- An in-vitro study
Authors: Kour Sukhbir , Kumar Ajay , Malik Azhar
Published: October 2022

The aim of the study is to compare the apical microleakage of two Bioceramic sealers Ceraseal, MTA Fillapex and an Epoxy resin sealer (AH Plus) with two different obturation techniques single cone and thermoplastic obturation techniques using dye extraction method.

80 mandibular single rooted premolars were decoronated, & biomechanically prepared. The samples were randomly divided into eight groups with ten samples (n=10). Group (A1) contained roots samples obturated with Ceraseal sealer and a single cone Gutta percha. Group (A2) constituted samples obturated using Ceraseal sealer and thermoplastic obturation. Group (B1) samples were obturated with MTA Fillapex sealer with a single cone. Group (B2) contained roots which were obturated using MTA Fillapex sealer with a thermoplastic obturation. Group (C1) contained roots samples obturated using AH Plus sealer with a single cone. Group (C2) samples were obturated using AH Plus sealer with thermoplastic obturation. Group D and Group E served as positive and negative control. Apical leakage was assessed using dye extraction method.

Warm or cold obtuartion technique using sealers with different composition does not totally eliminate apical microleakage.
Comparison of fracture resistance of mandibular central incisors following the use of two different spreaders during lateral condensation obturation technique- An in vitro study
Authors: Gupta Khushboo
Published: October 2022

The lateral condensation is the most commonly practiced obturation technique during root canal treatment. In this method, the use of spreaders is instrumental in acheiving 3-D obturation. These spreaders can create an unnecessary stress during use, by means of wedging force that might lead to vertical root fracture, resulting in failure of root canal treatment.

Sixty extracted mandibular central incisors were taken. All teeth were sectioned 2 mm coronal to CEJ and were wrapped in aluminium foil. The specimens were embedded in acrylic mould. Aluminium foil was scratched and the created space was filled with light body silicone impression material. Then, after working length determination, apical preparation was done with 40 no. K- file. Rest of the canal was prepared using step back technique. The samples were then randomly divided into 3 groups of 20 samples each. Group 1 No obturation (control group). Group 2 Obturation done using stainless steel finger spreaders. Group 3 Obturation done using nickel titanium finger spreaders. After the obturation, all samples were subjected to fracture using metal indenter on the universal testing machine. The load at which fracture occur was recorded. Data thus obtained was subjected to statistical analysis using ANOVA and TUKEY test.

The mean fracture resistance of group 1 was highest followed by group 3 (NiTi spreader) and least in group 2 (SS spreader).

NITI or SS spreaders can affect the fracture resistance of teeth during lateral condensation obturation technique.
A novel approach for retrieval of separated endodontic instrument: Two case reports
Authors: Kohli Tanvi , Hilal Syed Shahid
Published: October 2022

The most common endodontic mishap that eventually occurs during any root canal therapy is the separation of instrument inside the canal. The separated instrument influences the final outcome and prognosis of the root canal therapy. The clinician is confronted with a few options when considering this situation. These options can include leaving the fragment or incorporating the fragment to form part of the final obturation or removal from the root canal. Once the decision is made to remove the separated instrument, the clinician must realize that the procedure can be one of the most difficult treatments to attempt. This case report describes retrieval of separated instrument in the middle to apical third area using ultrasonic tips and braiding technique.

Purpose of this paper is to give an overview of various experimental methods for investigation of spin waves characteristics. Methods. The paper presents a description of a number of experimental techniques, such as the probing method, the phase shift method, the method of measure of equiphase dependences, the method of intersecting wave beams, and the use of Fourier analysis of the complex transfer coefficient of spin waves to determine their spatial spectrum. The conditions for using the listed methods and the characteristics of spin waves that one can measure by means of these methods are discussed in detail. Results. The paper presents a number of fundamental results that have been obtained on the basis of described methods. For example, the probing method was successfully used to visualize the amplitude and phase distribution of spin waves in the ferrite film plane and, in particular, it was used to experimentally confirm the previously predicted appearance of super-directed propagation of surface and backward volume spin wave beams. The phase-shift measurement method made it possible to measure the dispersion dependence of spin waves in ferrite structures such as ferrite – metal and ferrite – dielectric – metal, where measurements cannot be made by the probing method. The method of measuring equiphase dependences of spin waves made it possible, in particular, to measure for the first time with great accuracy the value of an external magnetic field magnetizing an yttrium iron garnet film to saturation in various crystallographic directions. The method of intersecting wave beams has made it possible to clarify the mechanism of parametric instability of surface spin waves. Fourier analysis of the complex transfer coefficient of spin waves allowed to determine the spatial spectrum of these waves; in particular, dispersion dependences of higher modes of the backward volume spin wave were first measured using this method. Conclusion. The methods described in this paper may continue to be successfully used for investigations of spin waves characteristics in various magnon crystals, ferrite structures and meta-structures.
Apophatic and Institutionalization: Pragma-Semantic Analysis
Authors: Tulchinskii G.L.
Published: October 2022

The article contains an attempt to generalize and systematize the content and role of the apophatic worldview attitude, which is characteristic of Russian culture. This attitude sources are determined by the specificity of the semantic picture of Eastern Christianity, by the political and economic history of Russia. From this point of view, culture acts as a pragmatic-semantic interface for the generation, selection, storage, reproduction, and transmission of social experience. The conducted consideration reveals the nature of the “rut” effect, the inverse nature of the development of Russian society in a new way. An analysis of the manifestations of this attitude in political life, economics, and artistic culture shows that apophaticism can act not only as a barrier, but also as a resource for the country development which implies a distinct socio-cultural engineering aimed at preserving and developing human and social capital.
The Philosophy of Generation of 1960s as a Social Phenomenon
Authors: Guseinov A.A.
Published: October 2022

In its main part, the article is devoted to the Soviet philosophy of generation of the 1960s. It begins with a preface, which regards belonging to a generation as a sign of fate, and ends with an afterword, according to which the past is not judged. Belonging to a generation is the seal of time on individual destinies. The author belongs to the generation of Soviet philosophers who directly followed the sixties and got lost in their shadow. It shows how they are seen from this close distance. They personified the renewal of philosophy in the Soviet Union in the second half of the 20th century. It is shown that it began at the Faculty of Philosophy of Moscow University in the form of opposition of young researchers to the dogmatically minded professors, that its origins were two outstanding thinkers – Evald Ilyenkov and Alexander Zinoviev, who set the speculative-dialectical and scientific-analytical lines of development of philosophical research with their work. The philosophy of the sixties was humanistically oriented and emerged as a decisive break with the philosophical dogmatism of the 1930s and 1940s; it was the theoretical justification for the process of de-Stalinization that had begun in the country. It was represented by many original theories of thought and action, inspired by the ideas of the sovereignty of the human mind and the individually responsible existence of the individual. The philosophy of the generation of the 1960s remained loyal to the teachings of Marx and the socialist ideal, existed, as it were, in parallel with official orthodoxy, with its internal rejection.
The Philosophers of the 1960s: Post-War Brotherhood of Fathers and Sons
Authors: Solov'jov E.J.
Published: October 2022

The article attempts a socio-genealogical analysis of the “philosophers of the 1960s”. This is how the literature of recent years refers to the generation of young philosophers who in the 1950s and 1960s opposed themselves to the dominant dogma and prepared the de-Stalinization of public consciousness. In the foreground are young front-line intellectuals enlightened by the war. The author talks about their hopes, which already foreshadowed the “thaw”; about stoic morality and courageous protest behavior in scientific and ideological discussions of the post-war period. Further, the life of the “younger growth” of the future “philosophers of the sixties” - schoolchildren of the late 40s – early 50s is covered in detail. Particular attention is paid to the understanding of education as a sacred duty to warrior fathers and a kind of youth cult of knowledge and science. The beginning of a long-term informal community of Soviet “philosophers of the sixties” was laid by a discussion about philosophy, which took place at the Faculty of Philosophy of Moscow State University in 1954. The author sees in it a bold and quite successful attempt at the philosophical reformation of Marxism. Two years before the 20th Congress of the CPSU, which called for the restoration of Lenin's norms of life, the “philosophers of the sixties” called for a return to Marx's norms of thinking. The last section of the article talks about the original concepts of thinking and consciousness that appeared in Soviet philosophy in the 60s and early 70s and sometimes had a neo-Marxist vision.
Labor and Labor Relations in the Horizon of Interdisciplinary Research
Authors: Przhilenskaya Julia G.
Published: October 2022

One of the most important factors directing philosophical thought to the phenomenon of labor is the development of such social sciences as economics, political economy, sociology, psychology, statistics, ergonomics, cultural studies, etc. The data obtained in the course of specific scientific research changed the angle of view of philosophers, and also influenced the quality of their analysis. In the article, the author analyzes from the standpoint of social philosophy, sociology, economics such phenomena in the labor market as the concept of labor standards, typical and atypical forms of employment, in particular, precarization of employment as one of the main trends in social life that changes the nature and essence of labor.
Chinese-Russian Energy Governance in the Context of Carbon Neutrality: Current Situation, Problems and Promotion Paths
Authors: Xiaohan Wang
Published: October 2022

2021 is a critical year for the transformation of China's energy industry. The path of clean and low-carbon energy has been determined, and the transformation of the energy industry is accelerated. China and Russia are both major energy countries and seek common interests in addressing climate change and energy cooperation. The relevance of this article is to analyze the current situation of energy cooperation between the two countries in terms of cooperation areas and other aspects by analyzing the research result from domestic and foreign researchers, and to identify the advantages and problems of energy cooperation by using SWOT analysis. The author proposes to explore and develop sustainable energy projects in Sino-Russian cooperation with the goal of “double carbon”, which is the countermeasure and promotion path of future long-term sustainable energy cooperation between China and Russia.
The US Congress and the Issue of Beginning the Iraq War: the Kurdish Factor in 2002-2003
Authors: Ayriyan Radmila S. , Lepkov Arseniy V.
Published: October 2022

The political discussions in the US Congress on the start of the war in Iraq and the fate of the Kurdish minority in this country are being explored. The arguments of supporters and opponents of the war in Iraq are analyzed through the prism of the Kurdish factor based on the transcripts of the US Congress, as well as materials from hearings in the Senate Foreign Relations Committee. It emphasizes the insignificance of the Kurdish issue in the initial period of discussion (the discussion on giving the US President the right to start military operations in Iraq), and the growing interest of legislators in the fate of the Kurdish population in January-March 2003. It is concluded that for the supporters of the invasion the Kurdish factor became the main one and the stake was placed on the need to overthrow Saddam Hussein because of his cruel attitude towards his own people, and in the camp of the opponents of the war the stake is placed on the thesis that the fate of the Kurds was known in 1980s but no one then decided to provide them with military support. The problem of double standards in American foreign policy towards both the Kurds, US allies in the region, and Saddam Hussein was first identified by the US Congress in 2003.
