Authors: KOYUNCU İlhan , BULUS Metin , FIRAT Tahsin
Published: December 2021

The aim of this study was to examine the moderator role of gender and socioeconomic status (SES) factors in the relationship between students' metacognitive skills and reading performance. The sample of the study was 6890 students in the age group of 15 years-old who participated in the Programme for International Student Assessment (PISA) in 2018 from Turkey. 3396 of the participants (49.30%) were female and 3494 (50.70%) of them were male. Of the participants, 2273 (32.99%) were classified as low, 2273 (32.99%) as medium and 2344 (34.02%) as high socioeconomic level. Moderator effects were tested with the multi-group structural equation modelling approach. Results revealed that SES and gender moderated the relationship between metacognitive skills and reading when controlling for other variables. Female students scored lower than male students in low and medium SES group, however they scored higher in the high SES group even after controlling for metacognitive skills, liking reading, and self-concept of perception of competence and difficulty. This means gender differences in reading scores were largely driven by SES. Therefore, the effect of these two factors should be taken into consideration while working on metacognition and reading. Moreover, it was advised to integrate training of metacognitive strategies in school curriculum and encourage reading engagement in order to reduce the effect of those factors.

Published: December 2021

The research is aimed at developing ideas and approaches to the implementation of the city manager model in modern Russian conditions. The research focuses on professionalization of municipal management, the practice of contractual hiring of city managers. There has recently been the acute controversy whether it is appropriate to implement the "city manager" model in modern Russian conditions, as there are cases of conflict interactions in political practice with the participation of a city manager. to the current study aimed to determine whether it is possible to balance interests and level conflict risks while optimizing the system for selecting and retaining professional personnel in municipalities. In order to answer this question we carried out a qualitative analysis of modern domestic and foreign studies, selected with the principle of scientific sources differentiation, as well as an expert survey of the heads of local authorities (582 experts from 76 regions of the Russian Federation), which made it possible to eliminate the "gap" between the theoretical substantiation models of a city manager in scientific literature and its real application in modern conditions. As a result of the study, the advantages and disadvantages of the "city manager" model were found, and the key mechanisms for reducing conflict risks during its implementation were identified. Based on the results obtained, we developed recommendations for changing the practice of hiring a city manager, which will eliminate the element of competition and confrontation in his interactions with the Head of the municipality, defining the hierarchical statuses of the two key figures of the municipality.

The imbalance between the demand for health services and their supply leads to a decrease in the availability of health care. The aim of the study is to analyze the key mechanisms of the policy on reducing the waiting time for planned medical care. The issues of ensuring the guarantee for maximum time limits are studied; the foreign experience of managing waiting times for medical care is reviewed, the possibility of applying it in Russian practice is analyzed; the possibilities of reducing waiting times at the level of medical organizations are considered. The review of foreign experience shows a purposeful state policy to reduce waiting times, and allows us to determine the most effective measures. In Russia, the guaranteed maximum patient waiting times are shorter than in most of the countries reviewed, however, state resources do not support these guarantees; there is no unified state approach for monitoring, and no well-thought-out mechanism for their regulation, based on both system capabilities and social needs. Taking into account the studied international and Russian experience, the recommendations for creating a system for managing the waiting time for planned medical care in Russia are proposed.

Authors:   Federal Customs Service of the Russian Federation, Davydov Ruslan
Published: December 2021

The article deals with the topical issue of assessing the efficiency of customs administration as one of the tools for the development of the Eurasian Economic Union (hereinafter - the EAEU). It is noted that there are significant differences in approaches to assessing customs administration in the EAEU member states, which creates obstacles to further integration of the EAEU. A comparative analysis of the existing systems for assessing the activities of the customs authorities of the EAEU countries is carried out, which implies the need for unification and standardization of customs operations and procedures, customs administration in general. Based on a comparative analysis of the customs practice of the EAEU countries, as well as existing international experience in unifying the work of customs administrations for the development of economic integration, a proposal was put forward based on the case study of the EU to harmonize the systems for assessing the efficiency of customs administration in the Eurasian Economic Union as a tool for its economic development.
FUNCTIONS OF STATE REGISTRIES OF NPOS IN THE DEVELOPMENT OF THE THIRD SECTOR: RUSSIAN EXPERIENCE
Authors:   National Research University Higher School of Economics, Laronov Andrei
Published: December 2021

Development of the third sector in Russia is accompanied with its maintenance of open-access state registries of non-profit organizations. Compared to the NPO registries in other countries, those in Russia appeared 10-15 years later and became new tools for the development of the non-profit sector. The purpose of this article is to categorize the functions of NPO registries in other countries, as well as suggest those attributed to Russian NPO registries. The following hypothesis is put forward in the article: Russian NPO registries have similar functions as registries in other countries, but they are currently not being fully implemented. There are four registries in the focus of the research: the registry of NPOs by the Ministry of Justice of Russia and three types of registries of socially oriented NPOs – recipients of state support, providers of social services, and providers of social care services. The research was carried out by analyzing legal acts which set up the registries, as well as analyzing the registries located on the Internet. The following functions have been suggested: collecting, systematizing and disclosing the information on the third sector; aggregating the data on supply and demand for NPO services; promoting cooperation of NPOs with the state and intersectoral partnerships; promoting government support to NPOs; as well as ensuring accountability of NPOs to the state and society. The hypothesis was confirmed: the functions are not fully implemented due to the lack of clearly defined goals when setting up registries, weaknesses of their structure and formats. Several recommendations were formulated to enhance the system of existing registries and their structure.
LAW ART
Authors: Chiodi Giovanni
Published: December 2021

Il secondo volume di LawArt ospita nella sezione Aperture due articoli che propongono, da diverse prospettive, un’affascinante analisi della rappresentazione artistica della forma scritta del diritto. Stefano Solimano traccia le origini e il destino del Code Civil del 1804 nella storia della sua illustrazione; prima come eredità e simbolo della persona di Napoleone, poi come strumento versatile separato dal suo ‘creatore’. Gianluca Russo conduce il lettore in una nuova e più complessa interpretazione della Allegoria della Giustizia, realizzata da Vasari nel 1543. Sebbene tradizionalmente considerata una trionfante raffigurazione della giustizia, l’auto­re mostra come la posizione e la specifica rappresentazione delle Pandette veicoli, invece, un messaggio storicamente contestualizzato di una molto più problematica e arbitraria (mal)amministrazione della giustizia.

Dostoevsky’s Three Hypostases [Review of:] Ivanov V.I. Dostoevsky. Tragedy-Myth-Mysticism. Ed. by A. B. Shishkin and O.L. Fetisenko. Saint Petersburg: Pushkin House Publisher, 2020. 476 p.
Authors: Kayanidi L.G.
Published: December 2021

This review presents an analysis of the new edition of the classic book on Dostoevsky written by the Russian modernist poet and thinker Vyacheslav Ivanov, who was the last representative of an entire era of Dostoevsky’s interpreters. At first, a brief description of each of the three sections of Ivanov’s book is offered. In these sections, Dostoevsky is interpreted as a tragic poet, a myth-maker, and a religious thinker. Along with it, some features concerning M.Yu. Koreneva’s new translation from German are also analyzed. Special attention is then paid to a number of extensive comments on Ivanov’s book, which often become separate studies concerning Ivanov’s most significant ideas, symbols and mythologies (for example, Ahriman, Lucifer, Psyche, transcensus, “You are”). Furthermore, an overview of the appendices included in the publication is given. Among these, the most significant are: the transcript of a text that S.N. Bulgakov discussed in the Moscow Religious and Philosophical Society “Russian tragedy”; some notes concerning the lectures on Dostoevsky Ivanov gave at the Baku University in 1921–1923; the text on Dostoevsky and Nietzsche which A. Kruchenykh discussed at the Baku University in 1921; some reviews in German on Ivanov’s book; the chronicle “Dostoevsky in the Life and Thoughts of V.I. Ivanov (1883–1949)” compiled by A.B. Shishkin and A.L. Sobolev. In conclusion, a review of a number of articles written by modern Ivanov scholars (A. B. Shishkin, M.B. Plyukhanova), which are also included in the appendices to the book, is presented.

Authors: Kovarsky S. L. , Petrukhina Yu. V. , Blokh S. P. , Zakharov A. I. , Bebenina A. A.
Published: December 2021

Disorder of sex determination is a condition associated with clinical and biochemical discrepancy between genetic, gonadal, and phenotypic sex of a child requiring detailed examination for final selection of sex. Indications for sex determination can arise both in infancy and during puberty. Several conditions pertaining to abnormal sex differentiation are manifested as normal male genitalia with Mullerian ducts derivatives.

The study objective is to present clinical observations of children with persistent Mullerian duct syndrome.

The study presents 2 clinical cases of children with disorders of sex determination. Both children were initially hospitalized at the surgical facility with cryptorchism diagnosis, Mullerian duct derivatives were found intraoperatively. During examination of the children (karyotyping, histological and immunohistochemical examination) in one case persistent Mullerian duct syndrome was diagnosed, in the other - chromosomal abnormality of sex formation (45,X/46,XY), mixed dysgenesis of the gonads.

If Mullerian duct derivatives are found during diagnostic laparoscopy, resection biopsy of the ambiguous gonad and intraoperative single-step urethrocystoscopy for visualization of the seminal colliculus and catherization of the uterus for its identification from the abdominal side should be performed. Further examination includes karyotyping, hormonal examination, consultations with an endocrinologist and a geneticist, and genetic examination if necessary.

The Relationship Between Social Capital and Acculturation Expectations of Estonians in Estonia: Perceived Threat as a Mediator
Authors: Rodionov G.Y.
Published: December 2021

This study examines the mediating role of perceived threat from other ethnic groups in the relationship between social capital and acculturation expectations of the host population. Consistent with Stephans’ theory, the article examined the impact of three types of perceived threat: economic, cultural, and physical. The sample consists of ethnic Estonians born and living in Estonia (N = 309). The study examined how the perceived threat affects the relationship between social capital indicators (general trust, ethnic tolerance, binding and uniting social capital) and acculturation expectations (“multiculturalism”, “melting pot”, “seg regation”). The results showed that physical perceived threat was a mediator of the relationship between ethnic tolerance and “multiculturalism”. With the increase in physical threat, the preference for “multiculturalism” decreased. Economic threat has been shown to mediate the relationship between general trust and “segregation”, as well as connecting social capital and “segregation”. In these two cases, the economic threat increased the likelihood of a preference for “segregation” by the host population. The mediative role of cultural threat was not confirmed in the present study.
Profiles of Multiple Social Identification and Attitude to Representatives of Other Nations in Russians and Bulgarians: A Cross-Cultural Analysis
Authors: Nosova K.
Published: December 2021

The paper explores latent profiles of social identification and attitudes to representatives of other nations in the cultural contexts of Russia and Bulgaria through the lens of personality-oriented approach. The research methodology included modified versions of social identity scales from the MIRIPS questionnaire and Verkuyten’s scale of religious identity. The online social psychological survey involved 234 Russians (66% females, 60% aged 30—49 years) and 278 Bulgarians (76% females, 45% aged 18-29). As a result, four latent profiles were identified in Russia (Internationalists, Individualists, Europeans, Nationalists) and three — in Bulgaria (Individualists, Europeans, Nationalists). Nevertheless, the content of the profiles as well as the features of the respondents constituting the profiles were similar. Nationalists displayed strong multiple identification and negative attitudes towards representatives of other nations; Individualists expressed weak multiple identification and negative attitudes towards representatives of other nations; Europeans demonstrated very strong European identification and positive attitudes towards representatives of other nations. The Internationalist profile was found only among the Russians and featured weak multiple identification and positive attitudes towards representatives of other nations. The paper concludes that there are both intercultural similarities and differences in the characteristics of the respondents that constitute each latent profile of multiple social identification and attitude to representatives of other nations.
On the Problem of Social Determination of Tool Behavior of Higher Animals: Structure and Features of "Social Contexts”
Authors: Fedorovich E.Y. , Sokolova E.E.
Published: December 2021

The article provides a review and critical analysis of recent primate wild population research revealing the significance of social interactions ("social contexts") for the development and maintenance of tool behavior in animals from the perspective of the Vygotsky — Leontiev school. As social contexts, we consider the role of "skilled" group members, primarily maternal individuals, as well as artifacts of animal tool activity. We argue that these new data don’t contradict the main statements of cultural and activity psychology regarding the fundamental differences between the psychological mechanisms underlying the process of social determination of animal and humans tool activity: namely, "skilled" animals, unlike humans, do not teach or encourage intentionally the attempts of naive individuals to develop tool actions, nor form their specific ways of handling tools; young primates do not seek help and support in acquiring and performing these actions. In addition, artifacts are perceived by animals primarily as preferred objects that have certain physical characteristics, for example, for extracting food, in contrast to human children, who adopt socially accepted techniques for handling them.

Authors: Su Xiaoguang , Han Bing , Jia Xingdong , Gao Yanjun
Published: December 2021

Objective to investigate the effect of 5-fluorouracil (5-FU) loaded carboxymethyl chitosan (CMC) nanoparticles on the apoptosis level of keloid fibroblasts. Methods keloid tissue (n = 80) was taken from inpatient and outpatient patients who were treated in our hospital from January
2020 to December 2020. The fresh keloid specimen tissues were washed with saline three times. After removing the epithelium, they were cut into 2mmx2mm tissue blocks for subculture. CMC nanoparticles loaded with 5-FU were prepared by ionically crosslinking CMC solution with calcium chloride.
The viability of fibroblasts was determined by MTT assay. Transwell was used to assess fibroblast invasion. The wound healing test was used to evaluate the migration of fibroblasts. The apoptotic cells were analyzed by Annexin V-FITC and flow cytometry. The expression of apoptotic protein
in fibroblasts was determined by Western blot analysis. The expression of transforming growth factor-β (TGF-β) and Smad2/3 were analyzed by immunohistochemistry. The mRNA expression of ERK1/2, protein kinase B (AKT) and nuclear transcription factor-κB (NF-κB) was analyzed
by RT-qPCR. Results compared with the control group, there was no difference in the viability of fibroblasts in the nanoparticle group at 0h (P>0.05), and the viability of fibroblasts at 24h, 48h and 72h decreased by 37.29%, 29.58% and 28.38, respectively (P<0.05). Compared with the
control group, the fiber cells composed of nanoparticles were less likely to pass through the pores of the basement membrane and their invasiveness decreased (P<0.05). Compared with the control group, the migration ability of fibroblasts in the nanoparticle group decreased (P<0.05).
Compared with the control group, the apoptotic rate of fibers composed of nanoparticles increased (P<0.05). Compared with the control group, the expression levels of Bax, Caspase-3 and Caspase-9 apoptotic proteins in the nanoparticle group increased (P<0.05). Compared with the control
group, the expression levels of TGF-β and Smad2/3 in the nanoparticle group decreased (P<0.05). Compared with the control group, the expression levels of ERK1/2, Akt and NF-κB mRNA in the nanoparticle group decreased (P<0.05). Conclusion 5-FU loaded CMC nanoparticles could
reduce fibrosis in keloids, lower cell proliferation, migration and invasion, and increase cell apoptosis by inhibiting TGF-β related pathways.

Authors: Zhang Yiping , Kurzinger Jan , Wilker Kolja
Published: December 2021

In order to improve the interaction performance between users and 3D interface in digital media, the optimization of 3D interface interaction in digital media is studied. Based on the results of ray tracing rendering of 3D visual interface, the optimization model of 3D interface
interaction in digital media is constructed by taking the visual attention allocation of the final layout of man-machine interface in digital media as the objective function, and man-machine constraints are added into genetic algorithm. In the process of solving the model optimization problem,
the genetic algorithm negates the gene that does not carry the man-machine constraint characteristics, and uses the particle swarm optimization algorithm to optimize the genetic algorithm, so that the genetic algorithm can quickly obtain the optimal solution of the optimization model. The
experimental results show that this method can improve the user’s gaze time for digital media software, and the user’s satisfaction with the use of the software is high.

Published: December 2021

Detection of stresses in structures is widely required. Acoustic stress measurement is a NonDestructive Evaluation (NDE) method. In this paper wave propagation in a stressed plate is studied, using numerical simulations. We used ABAQUS, a commercial finite element software, to model
the plate. Many parameters affect the wave propagation as plate thickness, plate length, and frequency of the wave signal are studied. When compressive and tensile loads are applied to a plate, the wave propagation is investigated. It was concluded that the effect of stress on the wave propagation
decreases with increasing plate length and also with increasing plate thickness, wherewith increasing frequency the effect of stress in wave propagation is clearer.

With the rapid development of technologies, such as big data, artificial intelligence, and cloud computing, the work cooperation among cities and the resources involved in business exchanges are deeply complementary. At the same time, information security has become one of the challenges
for smart cities, which is ubiquitous and easy to cause public security issues. For this reason, this research modeled the actual problems and then made decisions on resource allocation by considering full cooperation and non-cooperation situations. Their influence with respect to city size,
probability of intrusion by illegal users, and propagation probability of one-time intrusion were analyzed. Based on these foundation works, this research proposed incentive mechanisms to ensure the optimized information security for smart cities. These mechanisms ensure that cities not only
voluntarily increase the intensity of resource allocation to information security, but also make the co-operation in line with the reality. Therefore, this balances the advantages and disadvantages of non-cooperation and full cooperation, so as to ensure that the information security level
of urban agglomerations reaches the optimal state.

Smoking detection is an essential part of safety production management. With the wide application of artificial intelligence technology in all kinds of behavior monitoring applications, the technology of real-time monitoring smoking behavior in production areas based on video is
essential. In order to carry out smoking detection, it is necessary to analyze the position of key points and posture of the human body in the input image. Due to the diversity of human pose and the complex background in general scene, the accuracy of human pose estimation is not high. To
predict accurate human posture information in complex backgrounds, a deep learning network is needed to obtain the feature information of different scales in the input image. The human pose estimation method based on multi-resolution feature parallel network has two parts. The first is to
reduce the loss of semantic information by hole convolution and deconvolution in the part of multi-scale feature fusion. The second is to connect different resolution feature maps in the output part to generate the high-quality heat map. To solve the problem of feature loss of previous serial
models, more accurate human pose estimation data can be obtained. Experiments show that the accuracy of the proposed method on the coco test set is significantly higher than that of other advanced methods. Accurate human posture estimation results can be better applied to the field of smoking
detection, and the smoking behavior can be detected by artificial intelligence, and the alarm will be automatically triggered when the smoking behavior is found.

Periodontitis is a chronic oral inflammatory disease that is difficult to treat and is therefore the subject of clinical research seeking new and effective treatment. Nano-silver has antibacterial and anti-inflammatory effects; however, its application in periodontitis is not well
studied. In this study, we show decreases in periodontitis-associated inflammatory cytokines interleukin IL-4, IL-6, IL-8, IL-10, and tumor necrosis factor alpha (TNF-a) (P < 0.05) and in oxidative stress (P < 0.05) under intervention with nano-silver solution. The protein expression
of CCL21, heat-shock protein 90 (HSP90), andE-selectin in periodontal tissues decreased (P < 0.05), while bone structure improved (P < 0.05). This work suggests that nano-silver solution can effectively inhibit the inflammatory response and oxidative stress response of periodontitis
and improve the periodontal tissue and tooth structure to some extent; it may provide a new periodontitis treatment in the future.

To investigate intervention effect of music therapy combined with emotional valence on relieving depression in college students. The clinical data of 102 college students with depression who were admitted to our hospital (October 2017-0ctober 2018) were retrospectively analyzed,
and the students were randomly split into research group (n=51) and reference group (n=51). The reference group was intervened by music therapy, while the research group was intervened by emotional valence combined with music therapy. The intervention effect was compared between two groups.After
intervention, SAS scores in both groups were obviously lower (P < 0.001), and SAS scores in research group were obviously lower compared with reference group (P < 0.001). After intervention, GQOLI-74 scores in both groups were obviously higher (P < 0.001), and GQOLI-74 scores in research
group were obviously higher compared with reference group (P < 0.001). After intervention, SDSS scores in both groups were obviously lower (P < 0.001), and SDSS scores in research group were obviously lower compared with reference group (P < 0.001). After intervention, SES scores
in both groups were obviously higher (P < 0.001), and SES scores in research group were obviously higher compared with reference group (P < 0.001). After intervention, PSQI scores in both groups were obviously lower (P < 0.0), and PSQI scores in research group were obviously lower
compared with reference group (P < 0.001). After intervention, QSA scores in both groups were obviously higher (P < 0.001), and QSA scores in research group were obviously higher compared with reference group (P < 0.001). The introduction of music therapy combined with emotional valence
