Published: October 2022

Monoclonal antibodies are monospecific in nature and are produced by B-lymphocytes that are cloning of the same cell with exclusive affinity and specificity for a single antigen epitope. Medicines based on monoclonal antibodies are the most common, high-tech, sold and promising segment of the domestic pharmaceutical market. The article considers the possibilities and possibilities of the market for new biosimilar drugs in the dosage form of lyophilisate. The purpose of the work is to study the potential opportunities for localizing the production in the Russian Federation of drugs based on monoclonal antibodies in the dosage form of lyophilisate. The search was carried out by international non-proprietary names (INN) and anatomical-therapeutic-chemical classification (ATC) codes. In the study, methods of marketing analysis and the method of statistical data processing were applied. A study of the market for medicinal products based on monoclonal antibodies in lyophilic form produced in the territory of the Russian Federation showed its significant growth over the period from 2016 to 2020. In monetary terms, production increased from 1.997 to 7589 billion rubles, which amounted to 20% and 45%, respectively. As a result of the analysis, it was found that as of March 2022, the patent protection period for the following INNs has expired: basiliximab, infliximab, omalizumab, trastuzumab. An analysis of the structure of the LP wound based on monoclonal antibodies was carried out. All drugs based on monoclonal antibodies are included in the list of vital and essential drugs, the pricing of which is regulated by the state. The absolute volume of state financing of drugs based on monoclonal antibodies increased from 9,928 to 16,801 million rubles from 2016 to 2020. The dynamics of sales of medicines based on monoclonal antibodies has been studied. There is an increase in sales in physical and monetary terms of localized drugs based on monoclonal antibodies in lyophilic form, however, the potential for localization remains significant. A portfolio of drugs based on monoclonal antibodies in the dosage form «lyophilisate» has been formed, promising for localization of production in the Russian Federation in terms of the criteria for the expiration of patent protection and the level of sales in the Russian Federation.

Published: October 2022

Pandemi COVID-19 yang berkepanjangan secara global khususnya di Indonesia memberikan dampak yang besar bagi sektor pariwisata, khususnya bagi destinasi-destinasi pada 10 Bali Baru. Kampanye 10 Bali Baru ini merupakan program baru yang mau tidak mau terkena dampak besar akibat COVID-19. Dampak lainnya juag terlihat pada tindakan pengambilan keputusan dalam melakukan wisata pasca pandemic COVID-19. Pemerintah sampai saat ini masih berupaya untuk melakukan serangkaian kebijakan mitigasi bencana untuk menekan angka kasus COVID-19 dan bersiap untuk fokus pada strategi pemulihan pasca COVID-19. Seiring dengan hal ini, pelaku industri pariwisata di tengah keterbatasan yang ada juga dapat melakukan serangkaian strategi untuk mendukung pemerintah. Sebagai upaya membantu pemerintah dalam upaya mitigasi bencana pasca COVID-19, penelitian ini bertujuan untuk menjelaskan determinan keinginan wisatawan untuk melakukan kunjungan wisata pada salah satu destinasi 10 Bali Baru pasca pandemi. Penelitian ini merupakan penelitian kuantitatif dengan menggunakan pemodelan struktural Partial Least Square (PLS-SEM). Sampel acak pada penelitian ini sebanyak 235 wisatwan domestik yang pernah melakukan kunjungan ke salah satu destinasi 10 Bali Baru sebelum pandemi. Hasil penelitian ini menjelaskan bahwa consumer engagement dan destination image saat ini sangat mempengaruhi keinginan wisatawan untuk melakukan kunjungan setelah pandemi berakhir. Rasa cemas untuk melakukan kunjungan perlahan mulai bisa diterima dan dipahami sehingga tidak menjadi faktor pendorong yang mempengaruhi keinginan wisatawan untuk melakukan kunjungan.

Authors: Mukhametshina Dinara Rinatovna
Published: October 2022

The paper is devoted to identifying the features of the interaction between signs belonging to different semiotic systems in the context of Soviet political posters of the perestroika period. The study aims to identify the specific (universal and individual) characteristics of posters of the perestroika period as polycode texts. These texts are considered as special formations that are perceived through the visual communication channel, they combine verbal, graphic and iconic codes. Scientific novelty is accounted for by the fact that Soviet political posters of the perestroika period are little-studied in terms of the structure, extralinguistic basis and the functioning of elements of a heterogeneous (nonlinear) text. The study is novel in that it is the first to choose Soviet political posters of the perestroika period for analysis, as their content provides information about a person’s value attitudes, political preferences and worldview, as a rule, they carry a pragmatic attitude, i.e. they act as an instrument of influence on an individual and entire social groups. As a result, it has been proved that the specificity of these texts is determined by the author’s linguopragmatics and extralinguistic factors.
Tukay Studies in Germany: The View of the German Scholar Michael Friederich
Authors: Gimatdinova Guzel Ilsurovna
Published: October 2022

The research aims to trace changes in the attitude to the creative work of the Tatar poet Gabdulla Tukay in a historical retrospective based on the monograph “Gabdulla Tukay as an Object of Ideological Struggle” by the German Turkologist Michael Friederich. Using a number of examples, the paper shows that this work not only reflects the latest trends in foreign literary studies, but also is a kind of marker in foreign Tukay studies. M. Friederich explores scientific research of the Soviet period devoted to G. Tukay’s life and work both in the historical and political context, noting various objective and subjective factors that influenced the assessment and interpretation, gives original interpretations that differ from the prevailing Soviet ideologemes. Scientific novelty of the paper lies in determining the development of current trends in literary criticism in relation to G. Tukay in 1913-1980, in describing its evolution. The research findings amount to the substantiation of the influence that ideologies of various historical periods had on the literary criticism of G. Tukay’s creative work and to the identification of the attitude to this criticism and G. Tukay’s creative work of a scholar from a different culture.
Neologisms of Psychological Semantics of the Russian and English Languages as a Component of the Linguistic Worldview and an Object of Language Policy and Planning
Authors: Yudina Nataliya Vladimirovna , Seliverstova Oksana Aleksandrovna
Published: October 2022

Neologisms represent a layer of the latest vocabulary of any language. At the same time, the areas with the most intensive coinage of new words traditionally include technology, politics, ecology and economics. A significant number of new vocabulary of psychological semantics has been observed among commonly used vocabulary in the last decade. The study of such neologisms is particularly interesting through a comparative-contrastive lens. The aim of the paper is to assess the potential of neologisms of psychological semantics as a source of information about the linguistic worldview and the most productive ways of adding new words to the vocabulary of the language from the standpoint of cognitive linguistics and sociolinguistics. The neologisms selected for the purposes of the study were divided into semantic groups based on a semantic analysis. A structural analysis made it possible to identify ways of adding new words to the vocabulary of the English and Russian languages. The results of a comparative-contrastive analysis allowed the researchers to describe the differences in the linguistic worldview of the Russian and English languages based on vocabulary of psychological semantics for the first time, as well as the cognitive mechanisms underlying the most productive ways of creating neologisms, which constituted the scientific novelty of the study. As a result, the data on the ways of adding new words to the vocabulary of the English and Russian languages have been actualised, the productive word-formation models and methods of word formation have been identified. The expediency of purifying the Russian language from English-language borrowings has been considered.

Authors: Chaunina Natalya Vladimirovna , Kravtsova Polina Valeryevna
Published: October 2022

The paper is devoted to the study of the early creative work of the modern Russian-speaking Evenk poetess Varvara Danilova. The research aims to describe the characteristic features of the female persona in the poems from the collection “Only You...”. The paper analyses the image realisations of the female persona underpinned by both the thematic diversity of the works and the author’s worldview demonstrating the mixing of Russian and Evenk cultures. The paper is novel in that it is the first to identify and characterise the image realisations of the female persona in V. Danilova’s first collection of poems. It is shown how the nature and specificity of the persona’s image are revealed through landscape, detail and speech from the perspective of the author’s worldview, which fits in the context of the Russian and global literary tradition alike. As a result, the researchers have identified the “many faces” of the female persona: she is a woman who is in love and disappointed in love; a city dweller; a poetess; a Russian national; an Evenk woman who reveres national traditions; a Christian. It has been found that the image of the female persona combines features of the national Evenk mentality, all-Russian culture and personal, individual author’s, women’s history.
Symbols as a Reflection of A. Rand’s Philosophical Views in the Novel “Atlas Shrugged”
Authors: Mirasova Kamila Naeelovna
Published: October 2022

Ayn Rand (Alisa Zinovyevna Rosenbaum), a famous American writer of the XX century, who emigrated to the United States from post-revolutionary Russia at the age of 21, captured the readers’ attention in her historical homeland with great delay, only at the turn of the XXI century. In the short time since then, she has gained wide and, as well as in the rest of the world, ambiguous fame in Russia; she has become an object of criticism, but more from the perspective of her economic views than the literary merits of her works. The purpose of the paper is to demonstrate the literary features of “Atlas Shrugged”, the main novel in A. Rand’s creative work, in the light of the author’s philosophical ideas. The scientific novelty lies in the fact that Rand’s style has not yet been seriously analysed, despite the fact that Rand herself attached great importance to this aspect of literary creativity. The research findings have shown that the literary form of “Atlas Shrugged” has no less philosophical meaningfulness than its philosophical content.

Authors: Setiawan Yahya , Jondri Jondri , Astuti Widi
Published: October 2022

Online transportation is a transportation innovation that has emerged along with the development of online-based applications that provide many features and conveniences. In its development, many users wrote their responses to the application on social media such as twitter. Many opinions and responses are directly conveyed by users of online transportation modes to their official accounts. The responses given by these users are very large and can be used as sentiment analysis on online transportation. However, the analysis process cannot be done manually. Therefore, we need a system that can help analyze user responses on Twitter automatically. In this study, a sentiment analysis system was built for online transportation in Indonesia using the ensemble stacking algorithm, which will simplify and increase the accuracy of the sentiment analysis. Ensemble stacking is a solution for advanced machine learning methods that can improve the performance of the base classifier. The system built on ensemble stacking uses three base classifiers, namely SVM kernel RBF, SVM linear kernel, and logistic regression. The best accuracy result on the gojek dataset is 88%, and the best F1 score is 87%. Ensemble Stacking which is applied to the research that the author conducted on online transportation sentiment analysis on twitter, obtained better accuracy than the base classifier used.

In this paper we present new data on geology of the Kun-Manie copper-nickel-PGE sulfide deposit of the Kun-Manie ore field located on the eastern periphery of the Pristanovoy orogen in the southeast of the Siberian Platform, as well as a detailed description of ores and basic minerals and the distribution of PGE mineralization in ores of the deposit. The ore bodies are spatially associated with sills of the Late Paleoproterozoic Kun-Manie gabbronorite-websterite-lherzolite complex of 1.76–1.69 Ga. It has been established that the outlines of disseminated Cu-Ni ores and ore-bearing sills of mafic-ultramafic rocks match almost exactly. Breccia and massive ores are confined to schists of the upper and lower parts of the ore shoots. Patchy disseminated and vein-disseminated mineralization is concentrated in zones of ductile deformation and along contacts between rock layers of different competence. The main ore minerals are pyrrhotite, pentlandite and chalcopyrite; less common are pyrite, marcasite, cubanite, bornite, chalcocite, sulfoarsenides (gersdorfite, glaucodot), arsenides (nicolite) and tellurides (melonite) of nickel. Magnetite and ilmenite occur in small amount. PGE mineralization is represented by arsenides (sperrylite), sulfoarsenides (irarsite, holingworthite), tellurides (Pd-melonite, merenskite, kotulskite), and tellurobismuthides (moncheite, michenerite). Arsenides, sulfoarsenides and tellurides of PGE, Ni, Ag and Bi, native gold and silver were found in vein-disseminated, patchy disseminated and breccia Cu-Ni ores. The concentration of a considerable part of the main sulfide minerals and the productivity of PGE mineralization are assumed to be due not only to complex processes of magmatic differentiation, but also to sulfurization of magma differentiates in zones of ductile (tectonic) deformation under the influence of recrystallized fluids. The productivity of PGE mineralization characteristically increases with increasing fluid concentrations of S, As, Te, Bi, and Sb.

Published: October 2022

A number of university educators decided to implement an experience “pilot”: the co-creation of a blog with students in which they disseminated some topics of the subject “Spanish political system”, taken as part of a joint honors degree in law and political science from the Faculty of Political Sciences and Sociology of the Complutense University of Madrid. Four professors and 42 students participated in this experience. In the first phase, the students, under the supervision of the professors, collaboratively developed each of the assigned topics. To do so, the professors explained the dynamics, provided them with a series of resources, trained them in collaborative work techniques, supervised the whole process, and resolved all their doubts. In a second phase, they jointly evaluated one subject to see the possible deviations that had occurred with respect to the initial model, in order to be able to correct them in the rest. In addition, the professors conducted a student survey to measure teamwork and the impact of the blog, the results of which were shared with the participants and at specialized conferences. Thanks, this pilot program has shown that blogging is an important technological tool for the transformation and improvement of teaching and learning processes, and that it encourages the active role of students and promotes their collaborative learning, generating knowledge with and for students.
Indirect assessment of the rolling resistance of a car tire in the starting mode of motion
Authors: Karpenko Volodymyr , Voropay Oleksiy , Neskreba Eduard
Published: October 2022

Problem. From the condition of the tires and their correct choice depending on the weather conditions, first of all, the indicators of many operational properties of the car depend. The internal pressure and temperature of the tire increases during driving, as a result, there is a significant effect on the rolling resistance of the tire. At high values of the rolling resistance coefficient, first of all, fuel consumption increases, tire wear increases, etc. It is important to know how the rolling resistance coefficient changes during the starting period of motion. Goal. The purpose of this work is to determine the starting mode of motion time for specific vehicles. Based on the obtained dependences of the internal pressure and temperature of the tire on time, it is necessary to evaluate how the rolling resistance coefficient changes. Methodology. As a result of experimental studies, on vehicles equipped with tires of various sizes and seasonality, the dependences of the pressure and temperature of the tire material at three points (tread zone, shoulder part and sidewall) were obtained. Using the results of the experiment, as well as based on the dependencies presented in scientific papers devoted to the study of the performance characteristics of car tires, an indirect assessment of the rolling resistance coefficient when driving in the starting mode is made. Results. The value of the increase in the internal pressure of the gas filler in the tire has been established and the driving time for the studied vehicles in the starting mode has been determined. The most intense temperature rise is observed in the shoulder area of the tires. The temperature of the surface layer of winter tires increases less than summer tires, and, accordingly, driving on winter tires is safer at temperatures close to 0°C and below. Originality. A technique for indirectly assessing the rolling resistance of a car tire when driving in the starting mode (on "cold" tires) is presented, that is, knowing how the internal air pressure and tire temperature change, it is possible to predict a change in the rolling resistance coefficient. Practical value. Using the dependences obtained as a result of an indirect assessment of the rolling resistance of car tires, one can judge the value of the rolling resistance coefficient without resorting to experiments. The well-known assertion that it is necessary to timely replace summer tires with winter ones (when the ambient temperature can reach +5 ° C and lower) is confirmed, thereby significantly improving road safety.

Introduction. Restoration of blood supply to tissues is crucial for the regeneration of wound defects. The purpose of this research was to study the effect of piezoelectric polymers on the restoration of microcirculation and hemodynamics in the area of oral mucosa wound defects. Materials and methods. The study was carried out on 60 Wistar rats divided into four groups (15 rats each): control (intact) and 3 experimental groups. In group 1, the animals had an open wound defect. In groups 3 and 2, the rats had a wound defect covered with a membrane with and without copper modification, respectively. The specimens for subsequent light and electron microscopy were collected on days 3, 7, and 12. We studied qualitative and quantitative indicators of microcirculation and hemodynamics restoration. Results. Day 3: in all experimental groups, the arteriolo-venular relationship and the pericapillary diffusion index significantly decreased, while the Kernogan index increased. We also observed a significant increase in VEGF expression. Day 7: in experimental group 3, the values of the Kernogan index and the arteriolo-venular relationship were restored, and the pericapillary diffusion index remained significantly higher than in the control group. In the groups 1 and 2, none of the indicators reached the control values. VEGF expression decreased in all groups. On day 12 in group 1, the arteriolo-venular relationship, the Kernogan index and the index of pericapillary diffusion differed from the control group, in contrast to groups 2 and 3, where all the studied parameters were restored. Expression of VEGF in group 1 was significantly less than the control values, and in groups 2 and 3 it was significantly higher. Conclusion. We revealed that closing of oral mucosa wound defects by a piezoelectric polymer membrane led to the restoration of hemodynamic parameters and promoted active vascular formation.

Objective: The terms dissociative absorption and flow describe tendencies to experience immersive consciousness states, yet dissociation is sometimes considered maladaptive whereas flow is typically considered to be adaptive. We explored their trait and state associations with psychopathology, game task performance, and mood, and examined the hypothesized moderation effect of self-efficacy. Method: In the present study, 303 undergraduates completed trait questionnaires and 63 high/low absorbers reported their state before and after an immersive task (“Tetris”). Task performance was also assessed. Results: We found that flow was distinguishable from dissociation but was inconsistent; two of its components (“transformation of time” (ToT) and “merging of action and awareness” (MoAA)) were positively associated with dissociation and psychopathology, and, unlike other flow components, were unrelated to enhanced task performance. Although the trait associations of ToT and MoAA with psychopathology were not dependent on self-efficacy levels, trait dissociation was more strongly related to psychopathology under low self-efficacy. In the state phase, state immersion (both ToT and dissociative absorption) was associated with mood improvement, especially under low self-efficacy. Conclusion: Our results prompt us to question the validity of flow as a cohesive construct, as measured by the Dispositional Flow Scale-2. Immersive experiences, including ToT and dissociative absorption, led to short-term mood improvement in the state phase but, considering their trait associations with psychopathology, engaging in them excessively may be maladaptive in the long term.
STRATEGI PENGHIDUPAN BERKELANJUTAN MASYARAKAT PADA KAWASAN HUTAN MANGROVE DI MANDAH INDRAGIRI HILIR

Penelitian ini dilakukan di Kecamatan Mandah, Kabupaten Indragiri Hilir Provinsi Riau, pada dua cluster kondisi hutan mangrove di desa Pulau Cawan dan desa Bekawan. Pengambilan sampel dilakukan secara sensus. Rumah tangga nelayan di kedua desa menerapkan tiga jenis strategi mata pencaharian, yaitu strategi intensifikasi / ekstensifikasi, diversifikasi dan migrasi. Secara umum, strategi yang paling banyak digunakan di kedua desa adalah intensifikasi /ekstensifikasi diikuti oleh diversifikasi dan strategi migrasi. Berdasarkan hal ini, perlu untuk melestarikan hutan mangrove, karena strategi intensifikasi /ekstensifikasi memberikan tekanan tinggi pada hutan mangrove. Strategi penghidupan berkelanjutan yang dianut oleh rumah tangga nelayan adalah strategi diversifikasi dan migrasi, hal ini dikarenakan strategi ini tidak memberikan tekanan pada hutan mangrove dan berada di luar hutan mangrove karena masyarakat mencari alternatif pekerjaan lain atau keluar dari tempat tinggalnya. Di sisi lain, perlu juga mengadopsi strategi Silvofishery untuk melestarikan hutan mangrove dan meningkatkan produksi perikanan tanpa merusak hutan mangrove. Dengan kondisi hutan mangrove yang baik, pendapatan masyarakat akan semakin baik

Sometimes weak ties are just weak
Authors: Neal Zachary P.
Published: October 2022

Rajkumar et al. claim to provide causal support for the strength of weak ties. However, they do not show that weak ties are valuable, but instead that bridging ties are valuable. The confusion derives from an overlooked assumption in Granovetter's theory. When they exist, the most valuable ties for gaining access to unique information are strong bridges.

This study assesses the extent of selective hypothesis reporting in psychological research by comparing the hypotheses found in a set of 459 preregistrations to the hypotheses found in the corresponding papers. We found that more than half of the preregistered studies we assessed contain omitted hypotheses (N = 224; 52.2%) or added hypotheses (N = 227; 56.8%), and about one-fifth of studies contain changed hypotheses (N = 82; 19%). We found only a small number of studies with demoted hypotheses (N = 2; 1%) and no studies with promoted hypotheses. In all, 59% of studies include at least one hypothesis in one or more of these categories, indicating a substantial bias in presenting and selecting hypotheses by researchers and/or reviewers/editors. Contrary to our expectations, we found that added hypotheses and changed hypotheses were not more likely to be statistically significant than non-selectively reported hypotheses. For the other types of selective hypothesis reporting, no powerful test of the relationship with statistical significance could be carried out. Finally, we found that replication studies were less likely to include selectively reported hypotheses than original studies. Thus, selective hypothesis reporting is problematically common in psychological research and may partly be explained by the fact that authors do not specifically and clearly enough formulate hypotheses in preregistrations and papers. We urge researchers, reviewers, and editors to ensure that hypotheses outlined in preregistrations are clearly formulated and accurately presented in the corresponding papers.
The APC-Effect: Stratification in Open Access Publishing
Authors: Klebel Thomas , Ross-Hellauer Tony
Published: October 2022

Current implementations of Open Access (OA) publishing frequently involve Article Publishing Charges (APCs). Increasing evidence emerges that APCs impede researchers with fewer resources in publishing their research OA. We analysed 1.5 million scientific articles from journals listed in the Directory of Open Access Journals to assess average APCs and their determinants for a comprehensive set of journal publications, across scientific disciplines, world regions and through time. Levels of APCs were strongly stratified by scientific fields and the institutions’ countries, corroborating previous findings on publishing cultures and the impact of mandates of research funders. After controlling for country and scientific field with a multilevel mixture model, however, we found small to moderate effects of levels of institutional resourcing on the level of APCs. This is what we call the APC-Effect. Effects were largest in countries with low GDP, suggesting decreasing marginal effects of institutional resources when general levels of funding are high. Our findings provide further evidence on how APCs stratify OA publishing and highlight the need for alternative publishing models.
Altered hemispheric asymmetries as an endophenotype in psychological and developmental disorders: a theory on the influence of stress on brain lateralization
Authors: Berretz Gesa , Packheiser Julian
Published: October 2022

Hemispheric asymmetries are a basic organizational principle of the human brain and are ubiquitous in the healthy population. Several psychological and developmental disorders have been associated with atypical lateralization patterns, especially with a reduction of asymmetry. Among these disorders are major depressive disorder (MDD), schizophrenia, and autism spectrum disorders, which also show altered stress reactivity and elevated basal levels of the stress hormone cortisol. Recent research, however, has called the importance of altered asymmetries in these disorders into question. Especially for MDD, recent large-scale studies investigating altered asymmetries have not found any association. In this article, we propose that there is an association between altered asymmetry and depression but only for a subset of MDD patients. We present a theoretical framework in which we suggest that different symptom clusters expressed in mental and neurodevelopmental disorders could be associated with different neurostructural and –functional alterations, of which only few display altered asymmetry. Further, we propose that the development of a certain symptom cluster depends on the patient-specific etiology of the disorder and that a strong common factor in the development of the subtype with altered asymmetry across disorders is a chronically altered stress level as well as early life stress. To gather empirical evidence for this speculative theory, future research should focus on assessing and categorizing the etiology of disorders and different types of laterality changes on an individual patient level. Identifying different clinical subtypes and their different treatment prognosis would give rise to the possibility of sub-type-specific treatment plans and ultimately benefit patients.
