Published: February 2024

Background
To examine whether weekday-to-weekend sleep duration difference (WWD) and specific WWD patterns are associated with mental and somatic health and academic performance in a large student population.
Methods
This study utilized cross-sectional data from the SHoT-2018 survey which includes responses from 50,054 full-time university/college students in Norway. Participants completed online questionnaires and reported sleep duration separately for weekdays and weekends. Medium sleep duration was defined as 7 to 9 hours, short sleep duration as < 7 hours and long sleep duration as > 9 hours. Regression analyses were used to examine whether the degree and patterns of WWD was associated with health-related outcomes and academic performance.
Results
The mean WWD was 1 hour and 19 minutes. WWD was positively associated with higher odds of overweight/obesity, dissatisfaction with life, psychological distress, somatic burden and failed study exam. Further, short sleepers (on weekdays or weekends, or both) generally had higher odds of overweight/obesity, dissatisfaction with life, psychological distress, somatic burden and failed study exam, compared to medium sleepers. The odds of students reporting unfavorably on the outcomes were particularly high for those who slept short on both weekdays and weekends, while those who slept short on weekdays seemed to benefit from sleeping longer ("catching up") on weekends.
Conclusions
Overall, WWD was associated with adverse health outcomes for students. Short sleep duration both on weekday and weekend was associated with the most detrimental outcomes in terms of health and academic performance, while sleeping in on weekends may alleviate some of the detriments.
On the relationship between various anticoagulants and robot-assisted radical prostatectomy: a single-surgeon serial analysis
Authors: Farzat Mahmoud , wagenlehner florian m
Published: February 2024

Background and Objectives: Prostate cancer patients often have other health conditions and take anticoagulants. It was believed that surgery under anticoagulants could worsen surgical results. This study aims to explore the safety of robot-assisted prostatectomy in anticoagulated patients, without any exclusion criteria.
Methods: The study included 500 patients who underwent RARP by a single surgeon between April 2019 and August 2022. Patients were divided into two groups: Group 1, consisting of 376 men (75.2%), did not receive any anticoagulation, while Group 2, with 124 patients (24.8%), received different forms of anti-coagulation. Then the anti-coagulation group was divided into 4 subgroups according to their definite anti-coagulation. The aspirin 15,6%, new oral anticoagulants (NOAC) 5,4%, Vitamin K antagonist (VKA) 2%, and dual antiplatelet therapy (DAPT) 1,8% subgroup. postoperative complications and readmission rates were compared between the two study groups and subgroups.
Key findings : Patients in the combined group 2 were older and they also carried more comorbidities compared to men in group 1 (p=0.03, p=0.001).The study groups had similar oncological results, with 40.4% of patients having locally advanced cancers. Catheter days were longer in the anticoagulation group (4,5 vs 4 days, p=0.001). No significant differences were observed between study groups for overall, minor, and major complications (p= 0.160, 0.100, and 0.915 respectively). Additionally, readmissions were low (5.6%) and similar between study groups (p=0.635).
Conclusion: under cautious management, RARP under diverse anti-coagulation regimes is safe and has comparable results to men with no medications. Further prospective studies must be conducted to confirm our findings.

Authors: Yuan Lin , Chen Biyu
Published: February 2024

The conventional analysis method of influencing factors on the repurchase rate of cross-border e-commerce platforms mainly uses SPSS17.0 to obtain the influencing factors, which is vulnerable to the impact of customer experience competition, leading to the high variance between the influencing factor analysis groups. Therefore, an effective analysis method of influencing factors on the repurchase rate of cross-border e-commerce platforms in Hainan needs to be designed based on user experience. That is to say, the preference index of Hainan cross-border e-commerce platform repurchase is selected based on the repurchase impact variables of Hainan cross-border e-commerce platform, and then the contribution value of the variables is calculated using the stepwise regression analysis method, and the regression model of factors affecting the repurchase rate of Hainan cross-border e-commerce platform is constructed, thus realizing the analysis of factors affecting the repurchase rate of Hainan cross-border e-commerce platform. The case analysis results show that the inter group variance of the designed analysis method of factors affecting the repurchase rate of Hainan cross-border e-commerce platform based on user experience is small, which proves that the designed analysis method of factors affecting the repurchase rate is effective, accurate, and has certain application value, and has made certain contributions to improving the comprehensive sales profit of Hainan cross-border e-commerce platform.

Authors: Ghaedrahmati Mohsen , KavoshTehrani Masoud , Ebadian Hasan , Moosavi Seyed Ayoob , Maleki Abbas
Published: February 2024

High-power solid-state slab lasers face limitations in their performance due to thermal effects such as end effects, thermal gradients, and stress gradients, which cause optical path difference (OPD). To simulate thermal distribution and OPD in a diode-pumped high-power Nd:YAG slab laser, a combination of ray tracing and finite element method (FEM)was used. Furthermore, to calculate the OPD induced by the stress gradients, a formula was developed. In this geometry (inlet coolant velocity \({u}_{in}=0.3\frac{m}{s}\)), the peak to valley (P-V) value of overall OPD is \(10.2 \mu m\), and the thermal gradient in the coolant has the most impact on it. The simulation results indicated that changing the inlet coolant velocity from \(0.2\) to \(0.6\frac{m}{s}\) resulted in a decrease of OPD's P-V from \(13.1 \mu m\) to \(6.71 \mu m\).

Published: February 2024

Optical properties of InAs/GaAs (113)A quantum dots grown by molecular beam epitaxy (MBE) capped by (In,Ga)As. Have been investigated. The photoluminescence spectroscopy have been used to explain the optical properties of InAs QD. The reflection high-energy electron diffraction (RHEED) is used to develop the formation process of InAs quantum dots (QDs). A broadening of the PL emission due to size distribution of the dots when InAs dots are capped by GaAs and separation between large and small quantum dots, when they are encapsulated by InGaAs has been showed. The PL polarization measurements, have shown that the small dots, require an elongated form, but the large dots present a quasi-isotropic behavior. These results are due to hydrostatic and biaxial strain action on large and small dots grown under specifically growth conditions.

Role of GRA41 in Neospora caninum pathogenicity: insights into tachyzoite egress and microneme secretion
Authors: Yang Jing , Pei Yanqun , Wang Xianmei , Ying Zhu , Zhu Zifu , Liu Qun , Liu Jing
Published: February 2024

Background
Egress represents a crucial process employed by Neospora caninum in the establishment of infection. Dense granule proteins (GRAs), discharged by the dense granule, an essential secretory organelle of Neospora caninum, significantly contribute to the modification of parasitophorous vacuole, maintenance of morphology, and regulation of host cells. However, the precise involvement of these proteins in the egress process of tachyzoites remains inadequately characterized.
Methods
Comprehensive searches and comparative analyses were conducted of the homologous gene with dense granule protein 41 of Toxoplasma gondii, utilizing the NCBI and ToxoDB databases. Subsequently, we performed online bioinformatics analysis. Additionally, for ascertaining subcellular localization, we created an endogenously labeled strain expressing NcGRA41-3xHA. Employing CRISPR/Cas9 gene editing technology, we constructed the NcGRA41 knockout strain (Δncgra41) and NcGRA41 complementary strain (comΔncgra41) to analyze its phenotypes. To further elucidate the function role of NcGRA41, we performed a micronemes secretion assay and assessed the transcription levels of relevant factors during tachyzoites egress through RT-qPCR.
Results
NcGRA41 exhibited extracellular localization within dense granules and intracellular distribution in parasitic vacuoles. Deletion of NcGRA41 had no discernible impact on the invasion and proliferation of tachyzoites, but, markedly reducing the capacity for egress and pathogenicity in mice. The complementary strain recovered the phenotypic characteristic of Nc1 parasites. Further investigation revealed that the absence of NcGRA41 led to a reduction in gliding motility and the transcription level of subtilisin-like protein (SUB1). The microneme secretion assay demonstrated a significant decrease in the secretion level of NcMIC1, accompanied by reduced expression levels of NcMIC1, NcMIC4, and NcMIC8. These findings collectively contributed to the ultimate decrease in egress.
Conclusions
The identification of a novel Neospora caninum dense granule protein, designated NcGRA41, has been achieved. NcGRA41 is implicated in influencing the pathogenicity of N. caninum by modulating tachyzoites egress through the secretion of micronemes.
UAV Target Location Method Based on Image Matching
Authors: Fang Qunzhong , Xu Baoshu , Zhang Chengshuo
Published: February 2024

In the process of target matching and localization using unmanned aerial vehicles (UAVs), challenges arise due to rotation variations, illumination changes and the limited size of images captured from the UAV perspective, leading to ineffective feature extraction. This paper presents a target image matching algorithm based on the HardNet network, which decomposes the matching problem into two stages. In the object block detection phase, the selective search algorithm is used to detect objects in the image effectively using color and contour information, especially for the extraction of small targets. In the matching phase, the HardNet network is used to extract features from the detected object blocks, effectively overcoming nonlinear variations in angle and size to improve object feature extraction. Finally, the algorithm uses similarity metrics for image matching. The experimental results show that the proposed algorithm achieves higher near-field matching accuracy when tested on image datasets, outperforming the traditional SURF and SIFT algorithms by 8–11.0%. In addition, the algorithm demonstrates increased match detection rates and robustness in scenarios involving changes in image angle, illumination and size. This research provides a viable and effective approach to UAV target localization, particularly in scenarios involving close proximity and varying environmental conditions.
Design and Analysis of Gearboxes for Wind Power Systems
Authors: Bi Yadong
Published: February 2024

The effective and dependable functioning of wind turbines depends on the construction and assessment of gearboxes in wind power installations. In transferring rotational energy through the wind turbine rotors to the electric power source, gearboxes are essential, and their performance has a direct bearing on the total efficiency of energy conversion. Yet, gearbox malfunctions can result in a lot of lost productivity and expensive repairs. To achieve the best overall efficiency and dependability of wind power networks, early identification and prediction of gearbox defects is essential. In order to address this problem, we introduce in this paper a new enhanced harmony search optimization-based feed-forward neural network (EHSO-FNN) technique. First, 20800 cases total, with 2600 examples for each of the 8 health categories. These instances included typical and unusual fault circumstances with variable speeds and workloads. In this investigation, 2000 records from each sample were provided, recording important operational factors, including temperature, motion, and oil quality. By using min-max normalization to record the basic gearbox health details, this data is cleaned up and turned into useful features. By using MFCC to analyze the motion and Acoustic information collected by wind turbines, we are able to identify a group of specific characteristics that are highly effective in describing the state of the system. The most insightful and pertinent features from the retrieved MFCC feature set are then chosen using EHSO. At last, a FNN model based on the selected elements is created to carry out the fault prediction. The suggested method's performance is assessed using the metrics of accuracy (98.98%), precision (98.92%), recall (99%), f1-score (98.96%), RMSE (0.021), MAE (0.028), and MAPE (0.032). The experimental findings show that, when compared to other methods(1DCNN-PSO-SVM, LSTM,TSVR, WF-MMD-JDA,SVM, and SCADA-DBN), the suggested method obtains the best prediction performance.Early fault detection is made possible by the recommended way, which also enables preventive repairs and reduces downtime for wind turbine installations.

Published: February 2024

Coloured waste water possessing toxicity in the form of various dyes were used in several industries including paper pulp, textile, food, paint etc. Bio sorption is one of the best alternative for dye removal from wastewater. Coconut coir dust (CCD) is a light weight material with great porosity and high air content, hence is chosen for the present study specimen. The current work addresses the removal of hazardous sunset yellow (SY) FCF, a coloring ingredient frequently used in the food industry, from wastewater.The uptake capacity in batch and column mode is 82 mg/g and 160 mg/g respectively. The SEM images before and after biosorption of SY onto CCD also supported the binding between the adsorbent-adorbate interface. The comparative uptake capacity of SY with other follows the order as sal flower, Eucalyptus leaf, mahua seed and coco dust with values of 26, 31, 43 and 82 mg/g respectively which is maximum in case of CCD. Adsorption parameters like effluent pH, effluent dye concentration, dose, and contact time were optimized for estimation of adsorption capacity and rate constants. The output was better at high pH and lower concentration of dye. The kinetic study suggested pseudo second order rate revealing both adsorbate-adsorbent interdependency. The isotherm supported Langmuir model with monolayer and uniform adsorption at the interfaces. The spiked effluent testing showed that tap water had the lowest adsorption percentage (91.82%) and tube well water had the greatest percentage (98.37%). The real sample analysis with lab to land approach justified sustainability and commercial viability of the present work.

Published: February 2024

With the popularity of cloud computing, effective task scheduling has become the key to optimizing resource allocation, reducing operation costs, and enhancing the user experience. The complexity and dynamics of cloud computing environments require task scheduling algorithms that can flexibly respond to multiple computing demands and changing resource states. To this end, this study proposes an improved RTH algorithm, the ERTH algorithm, which aims to improve the efficiency and effectiveness of task scheduling in cloud computing environments. Evaluations in the CEC benchmark test sets show that the ERTH algorithm outperforms the traditional PSO and GWO in several performance metrics and outperforms the emerging GWCA and CSA. This result signifies a significant advancement of the ERTH algorithm in intelligent optimization. Further, we apply the ERTH algorithm to a real cloud computing environment and conduct a comparison with the original algorithm RTH, PSO, ACO, WOA, and HLBO. When dealing with cloud computing task scheduling problems, the ERTH algorithm demonstrates better task completion time, resource utilization, and system load balancing performance. Especially in high-load and complex task scenarios, the stability and scalability of the ERTH algorithm perform exceptionally well. This study not only reveals the powerful potential of the ERTH algorithm in cloud computing task scheduling but also brings new perspectives and solutions for cloud service providers in resource allocation and task scheduling strategies. The proposal and validation of the ERTH algorithm are of great significance in promoting the application of intelligent optimization algorithms in cloud computing.

Published: February 2024

Nearly seventy percent of diagnostic lab test errors occur due to variability in preanalytical factors.1–4 These are the parameters involved with all aspects of tissue processing, starting from the time tissue is collected from the patient in the operating room, until it is received and tested in the laboratory. While there are several protocols for transporting fixed tissue, organs, and liquid biopsies, such protocols are lacking for transport and handling of live solid tumor tissue specimens. There is a critical need to establish preanalytical protocols to reduce variability in biospecimen integrity and improve diagnostics for personalized medicine.2,5 Here, we provide a comprehensive protocol for the standard collection, handling, packaging, cold-chain logistics, and receipt of solid tumor tissue biospecimens to preserve tissue viability.

Published: February 2024

Background
Sepsis and acute respiratory distress syndrome (ARDS) are both associated with high morbidity and mortality, primarily due to systemic inflammation-induced tissue damage, resulting organ failure, and impaired recovery. Regulated extracellular matrix (ECM) turnover is crucial for maintaining tissue homeostasis in health and in response to disease-related changes in the tissue microenvironment. Conversely, uncontrolled turnover can contribute to tissue damage. Systemic Inflammation is implicated to play a role in the regulation of ECM turnover, but the relationship between the two is largely unclear.
Methods
Ten healthy male volunteers were intravenously challenged with 2 ng/kg lipopolysaccharide (LPS, derived from Escherichia coli) to induce systemic inflammation. Plasma samples were collected before (T0) and after (T 1h, 3h, 6h and 24h) the LPS challenge. Furthermore, plasma was collected from 43 patients with septic shock on day 1 of ICU admission. Systemic neo-epitopes of extracellular matrix turnover, including ECM degradation neo-epitopes of collagen type I (C1M), type III (C3M), type IV (C4Ma3), and type VI (C6M), elastin (ELP-3) and fibrin (X-FIB), as well as the ECM synthesis neo-epitopes of collagen type III (PRO-C3), collagen type IV (PRO-C4) and collagen type VI (PRO-C6) were measured by ELISA. Patient outcome data were obtained from electronic patient records.
Results
Twenty-four hours after LPS administration, all measured ECM turnover neo-epitopes, except ELP-3, increased compared to baseline levels. In septic shock patients, concentrations of all measured ECM neo-epitopes were higher compared to healthy controls. In addition, concentrations of C6M, ELP-3 and X-FIB were higher in patients with septic shock who ultimately did not survive (N = 7) compared to those who recovered (N = 36).
Conclusion
ECM turnover is induced in a model of systemic inflammation in healthy volunteers and was observed in patients with septic shock. Understanding interactions between systemic inflammation and ECM turnover may provide further insight into mechanisms underlying acute and persistent organ failure in sepsis.
Analysis and Mitigation of the Imbalance Impact on an Industrial Image Classification Dataset
Authors: Andrade Willian , Lazzaretti André Eugenio , Kondo Ricardo , Lopes Heitor , Oliveira Valmir
Published: February 2024

One of the most impacting problems in building machine and deep learning models for automated vision systems in industrial environments is the large variety of products in a real production line, which means that the dataset generated from the systems will be, most probably, imbalanced. Different approaches have been studied in the recent literature to reduce the effects of imbalanced data, still without a recommendation of a more adequate methodology for industrial scenarios. Hence, this paper compares three approaches for reducing the effects of imbalanced classes using a dataset of real images collected in an industrial production line: class removal, weight compensation, and data augmentation. We use a convolutional neural network as the backbone for the classifier of proposed method. Several comparisons are presented, emphasizing the advantages and limitations of each approach. Results show that data augmentation is the most promising approach for the evaluated dataset, improving the results and allowing the real-world application of the proposed method.

Published: February 2024

This work aimed to investigate Natural Language Processing (NLP) algorithms to automate the Fale Conosco (Contact Us) channel of SEFAZ-RJ, used to clarify taxpayers’ doubts sent via email. Due to the social distancing situation caused by the COVID-19 pandemic, the channel has become a consolidated means to address tax-related inquiries. Thus, employing Machine Learning/Deep Learning techniques, taxpayers’ doubts were classified with the objective of automating the response process. The results with the BERT-based model achieved an accuracy of 96.6%, contributing to a proposal for reformulating the taxpayers’ inquiry form, as well as indicating more promising techniques to initiate the automation process of the Fale Conosco channel at SEFAZ-RJ.

Authors: Costa José Alfredo , Dantas Nielsen
Published: February 2024

Text clustering analysis plays an important role in the organization and comprehension of extensive amounts of textual data. By grouping semantically similar documents into coherent categories, or clusters, it is possible to extract pertinent information and the unearthing of latent patterns embedded within the text. Text clustering enables a deeper understanding of the underlying structure and relationships within textual data, therefore, unveiling patterns and thematic trends. This paper aims to evaluate the impact of different text embeddings in the task of clustering Brazilian legal documents. The embeddings were obtained from BERT (Bidirectional Encoder Representations from transformers) models: Jurisbert, Bert Law and Irisbert. Term Frequency-Inverse Document Frequency (TF-IFD) was also used as a base representation model for comparisons. Nine different clustering algorithms were tested, including methods such as MB Kmeans, DBSCAN, BIRCH. Experiments were conducted in a database of 30,000 documents in Brazilian Portuguese of judicial moves of the Tribunal de Justiça do Rio Grande do Norte. To evaluate the performance of the clustering algorithms, the Normalized Mutual Info and Jaccard coefficients were used. Processing time are also described for the different algorithms. Results suggest better results with embedding “Irisbert” and TF-IDF when considering NMI and Bert Law and TF-IDF when considering Jaccard coefficient, although “Irisbert” also produced good scores.

Published: February 2024

On the basis of the materials of stateinyi spisok/list of files written by ambassadors Prince S. I. Kozlovsky and by clerk (diak) I. Zinoviev, the article details the history of their diplomatic trip to the Safavid state, in the context of both the realities of Russian-Iranian relations of the time and contemporary internal and foreign political processes in Iran. The source contains unique information: about the cities and towns of Iran, about the capital of the state — Isfahan, about the court of Shah ‘Abbas II, about his nearest circle, about the peculiarities of his life and his dignitaries, about the difficulties of controlling the frontier (the North Caucasus). Since the list of files itself is a kind of report, it duplicates the provisions of the tsar’s order issued to the ambassadors for their mission. A comparison of the data enables to determine the relative success of the embassy. Most of the points of the order were hypothetical in nature. Their implementation was supposed to be due to the initiative of the Iranian side, which did not happen in reality. Among the significant aspects addressed during the negotiations, which involved several rounds, were: the purchase of saltpeter for the sovereign’s treasury, the fate of Russian prisoners, and so on. The materials of the list also reveal secret agents’ activities of the ambassadors, who managed to acquire copies of the actual foreign diplomatic correspondence of Shah ‘Abbas II, previously not known in the Russian historiography.
The Mesolithic Epoch at the Kolyma River Basin
Authors:   North-Eastern Integrated Research Institute, Slobodin Sergei B. , Zelenskaya Alisa Yu. ,   North-Eastern Integrated Research Institute
Published: February 2024

The article is devoted to the history of the study of the Early Holocene antiquities of the Kolyma River basin, the archaeological research of which was started in 1946 by A. P. Okladnikov. During the first stage of work only Neolithic sites were identified. Studies in the 1970s–1980s led researchers to various opinions about the course of the historical development of this region at the turn of the Neo-Pleistocene and Early Holocene. A. Yu. Mochanov, based on the materials he studied on the Lower Kolyma, believed that in the Early Holocene there existed the Sumnagin culture, which he identified in Yakutia. N. N. Dikov singled out the Siberdik and Maltan Kolyma cultures, different from the Sumnagin culture, which, according to his scheme of the historical development of Kolyma, “prevented” Sumnagin culture from the spread both to the Kolyma and to the east of it. This dilemma of the Kolyma materials remained unresolved until recently. In the 1980s–1990s S. B. Slobodin discovered the Early Holocene Uolba culture on the Upper Kolyma with blade stemmed points, which was recorded from Yakutia to Chukotka and Kamchatka. The revision of the materials of the Multan site showed that it was not mistakenly attributed to the early Holocene. In 2017–2020, A. Yu. Zelenskaya explored the Burkhala site on the Upper Kolyma, 9,300 14С years old (10,510 cal. BP) with in situ materials associated with the Sumnagin culture. The outlined contours of the development of cultures in the early Holocene of the Kolyma basin will serve as guidelines both for practical work of identification and field studies of the sites, and for further expansion of the theoretical knowledge about the ancient cultures of the North-East of Russia.

Published: February 2024

In the context of urbanization processes and the territorial expansion of urban areas, the term "urban sprawl" or "urban sprawl" is used to describe the "phenomenon of urban sprawl. This is a complex geographical process, which can be investigated on the basis of modern remote sensing data, including the use of multispectral satellite images of the Landsat project. The study actualized the process of processing and analysis of images using modern GIS complexes. As a result, the methodology of interpretation, mapping and calculation of changes in the dynamics of urbanized area growth for St. Petersburg was presented and tested. Each image was classified using machine learning by height standards. A class of urbanized areas was separately identified for each year of analysis. As part of this work, a map of the dynamics of urbanized territories over the study period was constructed, and the growth of the area of territories over the analysis period was quantitatively calculated. As a result, Landsat project space images, obtained due to the capabilities of the USGS database, turned out to be quite effective for detecting urban areas, water bodies, unused land and vegetation cover. Testing of the method on the example of St-Petersburg allowed seeing the results of expanding the built-up territory at the expense of peripheral (suburban) zones, including the effect of suburbanization. Over 25 years, urbanized areas have expanded due to the construction of infrastructure road facilities and housing construction of both low-rise projects and residential buildings, as well as large residential complexes. Further development of this study will include the Leningrad Oblast contact area as part of the St. Petersburg urban agglomeration.
Placer-forming properties of gold mineralization of the «Verny» site of the Degdekan deposits in the black-shale strata (Magadan Oblast)
Authors:   North-East Interdisciplinary Scientific Research Institute named after N. A. Shilo of Far East Branch of the Russian Academy of Sciences, Litvinenko Ivan S.
Published: February 2024

The placer-forming properties of vein-disseminated gold-sulfide-quartz mineralization in carbonaceous-terrigenous rocks of the North-East of Russia are considered on the example of the «Verny» site of the Degdekanskoe deposit, localized in the Permian black shale strata of the Ayan-Yuryakh antiktinorium of the Verkhoyansk-Chukotka folded region. According to the results of studies of the conditions for the presence of native gold in sample material crushed to 1 mm, it was established that the degree of release grains of gold in fractions of 0.1–0.25 and more than 0.25 mm from this type of ores with the given parameters of their physical destruction averages 33 and 75 %, respectively.This determines the relatively high placer-forming capacity of this type of primary sources. Calculation of the balance of native gold during the formation of a segment of placer Degdekan Creek, closely associated with the ore zones of the Verny site, showed its enormous placer-forming capabilities even under conditions of periglacial lithogenesis.
Relational sociology of Harrison White and his followers: Towards a theory of sociocultural duality
Authors:   HSE University, Kovalev Daniil I.
Published: February 2024

The paper presents an overview of the history of the cultural turn in social network analysis. The cultural turn has proclaimed the crucial role of not only social but also cultural structures. On the one hand, cultural structures construct a context for social interactions. On the other hand, social network mechanisms determine the features of the use of symbolic forms by actors. According to Harrison White and John Mohr, sociocultural duality can be defined as a process of mutual construction of social and cultural orders. It should be noted that the idea of White about the mutual construction of culture and structure (the concept of netdom) has become a starting point for theoretical and empirical debates on the duality of social and cultural networks. The concept of network domain (netdom) includes both social networks (net) and spaces of symbolic forms (dom). Hence, the task of this paper is to identify the theoretical and methodological arguments of researchers emphasising the importance of sociocultural duality. The paper discusses in detail the concepts of duality and relational sociology. But the main part of the article is focused on the analysis of the relational sociology of Harrison White and his followers (A.Mische, J.Fuhse, N.Crossley). Relational sociology rejects substantialist ideas and, therefore, it is directed to the research of processual social and cultural structures. The final arguments summarise cutting-edge topics for future research on sociocultural duality.
Values in the moral dimension of law: the dispute with A.V. Polyakov in the works of P.P. Serkov. View of the Petersburg school

Published: February 2024

The article presents a general characterization of three monographs by professor Peter Pavlovich Serkov — “Legal relationship (Morality of modern legal regulation)”, “Legal relationship (Theory and practice of modern legal policy). Part one: legal doctrine and measures of legal policy” and “Legal relationship (Theory and practice of modern legal policy). Part Two: Generalization of legal experiences of ascent to human, society and state” — and the analysis of some key provisions of the first of these monographs is presented, taking into account the polemics with the Petersburg school of philosophy of law, represented by A. V. Polyakov’s communicative approach to law, which is expressed on the pages of these monographs. The authors emphasize that the problem of the correlation between law and morality is a key problem of both legal theory and legal practice. This issue is particularly relevant in light of the goals and objectives defined by the Fundamentals of State Policy on Preservation and Strengthening of Traditional Russian Spiritual and Moral Values, approved by Presidential Decree No. 809 of 09.11.2022. Moral and ethical values should be taken into account in the processes of creating legal rules, applying legal rules, interpreting the law precisely because the value aspect in the law, expressed in its moral dimension, is an integral part of the law itself or a necessary condition for its existence and functioning — this idea unites the works of both professor P. P. Serkov and professor A. V. Polyakov. And, moreover, despite the criticism targeted at A. V. Polyakov as presented in the monograph of P. P.

The article is devoted to the study of the legal nature of judicial conciliation procedures int he civil process. On the basis of a theoretical analysis of the approaches to the concept of “procedural form of protection” existing in the procedural doctrine, the essence of judicial conciliation procedure as a part of civil and arbitration proceedings is revealed. The difference between judicial conciliation and extrajudicial conciliation procedures is shown. The onto-logical connection of the fundamental principles of civil procedural form and judicial conciliation procedures is proved. Guided by the achievements of the science of civil and arbitration procedural law and the materials of the practice of arbitration courts, the authors establish the degree and limits of the impact of the imperative and dispositive principles of state proceedings on the order of organization, conduct and results of judicial conciliation procedures. It is concluded that the excessive penetration of freedom into the sphere of judicial reconciliation contradicts the essence of the civil process as a form of administration of justice and can lead to abuse both by the participants in the trial and by the court. It is proposed to consolidate at the legislative level the imperative procedure for organizing and conducting judicial conciliation, its stages and stages, requirements for the candidacy of a judge-conciliator, his rights and obligations, as well as responsibility for the results of judicial reconciliation. The results of judicial reconciliation, their legal consequences are analyzed. The features of judicial conciliation in proceedings on cases arising from administrative and other public legal relations, which are also proposed to be regulated, are revealed. It is proposed to comprehensively fix the grounds, conditions and legal consequences of the judicial conciliation procedure in the field of resolving public legal conflicts.

The article is devoted to the analysis of legal norms, both directly and indirectly protecting the work capacity of employed citizens through ensuring the safety of their work. The labor legislation calls the principles of such provision the warning and prevention of hazards; minimization of damage to the health of workers. In this regard, labor law, not being an independent tool that ensures the prevention of diseases of citizens, acts as an element of the general legal mechanism of preventive medicine. The employer is obliged to implement such a mechanism through various control measures, including medical examinations of employees. At the same time, the authors emphasize that the goals of carrying out any preventive medicine measures lie in the private-public sphere, which makes it possible to maintain both the health of a particular citizen (individual health) and to identify patterns of development of public health, ways to maintain, protect and improve it. The analysis of labor-legal aspects of the correlation of private and public interests in the field of preventive medicine gives the authors the opportunity to identify two big issues. The first problem is related to the definition of the boundaries of responsibility of employers and the state (society) on issues of health protection of employees who are members of society as a whole. The second problem lies in the plane of the correlation of labor rights and obligations of employees in the field of preventive medicine with their personal rights. It is concluded that for an employer in the field of labor protection, the risk factors for the health/ill health of an employee are not general, but professional. Accordingly, the list of medical interventions (studies) carried out at the expense of the employer within the framework of mandatory medical examinations should correlate with such risks.

The article is devoted to the study of linguopragmatic characteristics of media text in the context of information and psychological impact on individual and collective addressee in the context of mass information broadcasting. As is known, as a special form of text existence in the modern information space, media text contains not only verbal elements realizing direct speech impact, but also non-verbal ones. This symbiosis of verbal and non-verbal means, as well as a number of pragmatic factors and attitudes, multiply the persuasive potential of a modern media text. In this connection, following other scientific fields, linguistics enters into interaction with the phenomenon of informational and psychological impact, which combines linguistic and extra-linguistic aspects of communication. From a structural point of view, media text is a complex communicative organization that combines text, hypertext, dynamic and static images, sound and provides non-linear, multi-channel, multi-layered and multi-dimensional perception of the embedded conceptual meanings, creates opportunities for feedback. What makes a modern media text polycode-multimodal. The purpose of this article is to analyze the linguopragmatic characteristics of the media text as the main form of realization of information influence. We use descriptive, synchronic-diachronic and functional research methods, as well as methods of contextual and communicative-pragmatic analysis. Based on the results of the study, we analyzed and described in detail the linguopragmatic characteristics of the media text as the main form of realization of information and psychological impact on the addressee in the modern information and communication space.
In the face of a threat: A study of political discourse based on the speeches of American presidents

Analysis of the structural elements of the media space and communication mechanisms that shape the information picture of the world and construct the image of socially significant facts remains relevant in the eventful context of modern life; each time it requires fresh empirical material for research. The article analyzes State of the Union addresses of US Presidents in 2003 and 2022 — by George W. Bush and J. Biden — to identify the crypto components, or hidden aspects of leadership that are manifested in both speeches. The choice of sources is related to the current situation in the world, in which one can see some similarities with the context of the presidential speech twenty years ago. The study of texts included two stages: quantitative content analysis and qualitative discourse analysis. To highlight the semantic priorities of the texts, the methods of quantitative linguistics were used; calculating the frequency of linguistic units made it possible to determine the key words of the discourse and its main conceptual vectors. The qualitative analysis of the semantic and pragmatic aspects of information showed that both speeches were characterized by the use of such strategies as generalization, example, amplification, concession, repetition, and contrast. The study revealed that many common features in the speeches were due to the specifics of the genre — both in the lexical content and in the choice of strategies for influencing the audience. Both speeches contain a large number of units referring to the socio-political realities of the era; in their structure, the role of personal pronouns is extremely high, which helps create images of politicians with outstanding leadership qualities that are necessary to unite their people. The analysis also made it possible to highlight a number of peculiarities, both in the agenda and in the choice of means of expression.
The internet-meme and the ethics: A review of scientific research for 2018–2022
Authors:   St. Petersburg State University, Glikina Anna V.
Published: February 2024

The article accumulates, systematizes and qualifies the most significant modern and relevant scientific works in the field of digital ethics and memetics over the past five years by means of a semisystematic analysis. This method allows us to consider various areas of research for a specified period and provide an overview of scientific sources on issues of digital ethics and memetics. The studies reviewed by the author were selected on scientific and technical bases as eLibrary, CyberLeninka and CORE according to the following keywords: Internet meme, memetics, digital ethics, ethics of a journalist, social networks. The author’s focus is on identifying gaps in research on both internet memes and digital ethics. The author aims to identify different aspects of the relationship between the Internet meme and the ethics of its creation and distribution, as well as to outline the prospects for further research of the problems raised. The presented article specifies the range of existing semantic gaps in scientific concepts and identifies the main lines of development of the problem. As a result of the study the author notes that the study of creolized texts comes down to three problematic issues: how they influence the user’s picture of the world, how they become popular and who creates them. At the same time, the ethical side of the issue is not touched upon by the authors in their works. Most scholarly articles on digital ethics and journalism ethics boil down to three areas: analysis of codes of ethics, analysis of user behavior on social networks and analysis of the spread of fake information online. Thus, the author concludes that digital ethics scholars almost never consider Internet memes as a subject of study, and vice versa, researchers of Internet memes rarely address ethical issues in their works.
