Медиааналитика в библиотечных исследованиях

The paper goal is to define the role of media analytics in library research. The author characterizes the main types and methods of applied library research (sociological, library statistics, bibliometrics). As the media tools used in applied library studies are limited, the author discusses the potentialities of media analytics as a new and promising research vector. Monitoring of library media presence enables to assess the library’s communication PR policy, its ability to attract audience attention, and to demonstrate its potential and social role. The functionality of Medialogia computerized mass and social media monitoring system is discussed; the data formats, tools and library opportunities are examined. The media analytics methods, i. e. monitoring, statistical and infographical methods, as well as content analysis, are described. The author analyzes the results of search of RNPLS&T media hits in the period from May 30, 2021, to May 30, 2022. She concludes that the Library has been intensifying its media activity, and its PRperformance has been increasing. The author also offers the recommendations on upgrading this vector of activities and on how to enhance the role of media analytics in the applied library research.Цель статьи – определение места медиааналитики в библиотечных исследованиях.

Dopamine Sensor Based on a Composite of Silver Nanoparticles Implemented in the Electroactive Matrix of Calixarenes

A sensitive electrochemical sensor based on a composite containing silver nanoparticles and a redox active thiacalixarene with catechol fragments in the substituents at the lower rim has been developed and used for dopamine detection. The electrochemical investigation of thiacalixarene in homogeneous solution and on the electrode interface showed the reversible character of the redox conversion of catechol fragments and its involvement in the chemical reduction of silver which resulted in formation of uniform nanoparticles of 4-6nm in diameter. The use of such a material for electrode modification made it possible to record a high amplitude cathodic signal at -700mV that was proportional to the dopamine concentration within 1nM-1μM. (limit of detection 0.5nM). © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

A Review of the Properties of Nb3Sn and Their Variation with A15 Composition, Morphology and Strain State

This article gives an overview of the available literature on simplified, well defined (quasi-)homogeneous laboratory samples. After more than 50 years of research on superconductivity in Nb3Sn, a significant amount of results are available, but these are scattered over a multitude of publications. Two reviews exist on the basic properties of A15 materials in general, but no specific review for Nb3Sn is available. This article is intended to provide such an overview. It starts with a basic description of the Niobium-Tin intermetallic. After this it maps the influence of Sn content on the the electron-phonon interaction strength and on the field-temperature phase boundary. The literature on the influence of Cu, Ti and Ta additions will then be briefly summarized. This is followed by a review on the effects of grain size and strain. The article is concluded with a summary of the main results.Comment: Invited Topical Review for Superconductor, Science and Technology. Provisionally scheduled for July 200

Students’ Subjectness, Self-Efficacy and Psychological Well-Being: Comparative Research of Russian and Kazakhstan Students

The relevance of the study is due to the need to resolve the contradictions between the requirements of higher education for the personality of a young person and his real capabilities, manifested in the ability or inability to be the subject of his activity and his development. The need to resolve this contradiction has determined the purpose of this study – to identify the level of expression and structure of the subjective properties of students’ personality, their relationship with self-efficacy and psychological well-being. The work used a set of theoretical and empirical research methods, in particular, questionnaires to identify the level of an individual subjectivity development (M.A. Shchukina), general and social self-efficacy (M. Sherer and J. Maddux, adaptation by A.V. Boyarintseva), psychological well-being (K. Riff, adaptation by T.D. Shevelenkova and P.P. Fesenko). Mathematical processing was carried out using the criterion ϕ* – Fisher’s angular transformation, as well as methods of correlation analysis using the linear Pearson correlation coefficient. The subjects were students of a number of universities of the Russian Federation and the Republic of Kazakhstan. A total of 277 students majoring pedagogy and psychology took part in the study, among them 266 (96%) women, 11 (4%) men, average age 19.5 years (SD=1.5). As a result, no fundamental differences were revealed in the structure and manifestations of subjectivity depending on the place of residence, national and cultural traditions, which indicates the existence of some general patterns in the formation of the subjectivity of a future teacher or psychologist. A high level of subjectivity was identified in 57.04% respondents, medium – in 38.98%, low – in 3.98%. It has been established that the level of subjectivity positively correlates with self-efficacy in objective activity, with social self-efficacy and with the psychological well-being of an individual. It was revealed that students with low subjectivity can also have a high level of psychological well-being, while performing a compensatory function. The results obtained can be used in the course of student training, as well as in the work of curators of student groups and in the activities of the psychological service of universities

Pectobacterium atrosepticum exopolysaccharides: Identification, molecular structure, formation under stress and in planta conditions

© The Author 2017. Published by Oxford University Press. All rights reserved. In the present study, we identified exopolysaccharides of the harmful phytopathogenic bacterium Pectobacterium atrosepticum SCRI1043 and characterized the molecular structure of these polymers. The synthesis of the target polysaccharides was shown to be induced under starvation conditions. Moreover, intensive accumulation of exopolysaccharides occurred during the colonization by bacteria of the xylem vessels of infected plants, where microorganisms formed specific 3D "multicellular" structures-bacterial emboli. Thus, the identified polymers are likely to be involved in the adaptation and virulence of bacteria of Pectobacterium genus

Coping Responses During the COVID-19 Pandemic: A Cross-Cultural Comparison of Russia, Kyrgyzstan, and Peru

Background. The COVID-19 pandemic has subjected people around the world to severe stress, evoking a variety of coping responses. Coping responses can be broadly classified into four strategies: 1) problem-focused coping; 2) emotion-focused coping; 3) socially supported coping; and 4) avoidance. While there is a wide variability of individual coping responses, to some extent they are also culturally specific. Objective. This study aimed to compare the differences in the prevalence and factor structure of coping responses during COVID-19 pandemic in three countries: Russia, Kyrgyzstan, and Peru. Design. The sample included 501 participants from Russia, 456 participants from Kyrgyzstan, and 354 participants from Peru. The mean age of participants was 28 years in Russia (SD = 13.5); 24 years in Kyrgyzstan (SD = 10.0); and 30 years in Peru (SD = 12.3). In Russia and Kyrgyzstan, coping strategies were assessed with an abbreviated Russian adaptation of the COPE (Coping Orientations to Problems Experienced) questionnaire. In Peru, coping responses were assessed using the Spanish version of the Brief COPE questionnaire. The average scores from fifteen COPE scales were used as the input data for linear modelling and factor analysis. Results. The coping scores varied substantially within each country. Differences between countries accounted for 17.7% of the total variability in religious coping; 15.8% in acceptance; 13.9% in mental disengagement; and less than 7% in the other coping strategies. No difference in the prevalence of coping responses was found between Russian and Kyrgyz participants after accounting for age and gender. In all three countries the coping responses were associated with the same four coping domains: problem-focused coping, socially supported coping, avoidance, and emotion-focused coping. Four factors explained up to 44% of the total variation in the COPE scores. Religious coping and mental disengagement were classified into different coping domains in the three countries. Conclusion. The results suggest that during the COVID-19 pandemic, people from different countries apply the full range of coping responses within the four universal coping strategies. Religious coping and mental disengagement differed the most across the countries, suggesting that some coping behaviors can take on different roles within the system of coping responses to stressful events. We attribute these differences to differing cultural and socioeconomic characteristics, and the different measures taken by governments in response to COVID-19. © 2020.

Decrypting magnetic fabrics (AMS, AARM, AIRM) through the analysis of mineral shape fabrics and distribution anisotropy

The fieldwork was supported by the DIPS project (grant no. 240467) and the MIMES project (grant no. 244155) funded by the Norwegian Research Council awarded to O.G. O.P.'s position was funded from Y-TEC.Anisotropy of magnetic susceptibility (AMS) and anisotropy of magnetic remanence (AARM and AIRM) are efficient and versatile techniques to indirectly determine rock fabrics. Yet, deciphering the source of a magnetic fabric remains a crucial and challenging step, notably in the presence of ferrimagnetic phases. Here we use X-ray micro-computed tomography to directly compare mineral shape-preferred orientation and spatial distribution fabrics to AMS, AARM and AIRM fabrics from five hypabyssal trachyandesite samples. Magnetite grains in the trachyandesite are euhedral with a mean aspect ratio of 1.44 (0.24 s.d., long/short axis), and > 50% of the magnetite grains occur in clusters, and they are therefore prone to interact magnetically. Amphibole grains are prolate with magnetite in breakdown rims. We identified three components of the petrofabric that influence the AMS of the analyzed samples: the magnetite and the amphibole shape fabrics and the magnetite spatial distribution. Depending on their relative strength, orientation and shape, these three components interfere either constructively or destructively to produce the AMS fabric. If the three components are coaxial, the result is a relatively strongly anisotropic AMS fabric (P’ = 1.079). If shape fabrics and/or magnetite distribution are non-coaxial, the resulting AMS is weakly anisotropic (P’ = 1.012). This study thus reports quantitative petrofabric data that show the effect of magnetite distribution anisotropy on magnetic fabrics in igneous rocks, which has so far only been predicted by experimental and theoretical models. Our results have first-order implications for the interpretation of petrofabrics using magnetic methods.Publisher PDFPeer reviewe

Легочная гипертензия, ассоциированная с портальной гипертензией, и легочная гипертензия при саркоидозе органов дыхания: сложные патогенетические взаимоотношения

 In the literature review, modern views on the features of pathogenesis and diagnosis of pulmonary hypertension associated with portal hypertension and sarcoidosis of respiratory organs are presented. A variety of views is due to the lack of a convincing evidence base underlying the algorithm for diagnosis and treatment of this pathology. Pulmonary hypertension is one of the most complex cardiological problems and represents a pathological condition that is based on increasing resistance to blood flow in a small circle of blood circulation at any of site. Unlike the systemic arteries, there is no direct access to the pulmonary artery for measuring blood pressure by non-invasive methods, so the diagnosis of pulmonary hypertension in the early stages, before the formation of a lesion in the target organ, which is the right ventricle of the heart, is practically impossible. In actual clinical practice, pulmonary hypertension is at best diagnosed at the stage of latent right ventricular dysfunction, which is manifested by dilatation of its cavity and / or hypertrophy of its walls, at worst at the stage of right ventricular heart failure. At present, there has been a trend towards an improvement in the diagnosis of pulmonary hypertension (LH) in various diseases. This is the reason for the special interest in this interdisciplinary problem.В обзоре литературе представлены современные взгляды на особенности патогенеза и диагностику легочной гипертензии (ЛГ), ассоциированной с портальной гипертензией и саркоидозом органов дыхания, что обусловлено отсутствием убедительной доказательной базы, лежащей в основе четкого алгоритма диагностики и лечения данной патологии. Легочная гипертензия является одной из самых сложных кардиологических проблем и представляет собой патологическое состояние, в основе которого лежит повышение сопротивления току крови в малом круге кровообращения на любом из его участков. В отличие от системных артерий к легочной артерии нет прямого доступа для измерения артериального давления неинвазивными методами, поэтому диагностика ЛГ на ранних стадиях, до поражения органа-мишени, которым является правый желудочек сердца, практически невозможна. В реальной клинической практике ЛГ в лучшем случае диагностируется на стадии скрытой дисфункции правого желудочка, которая проявляется дилатацией его полости и (или) гипертрофией его стенок, в худшем – на стадии правожелудочковой сердечной недостаточности. В настоящее время отмечена тенденция к улучшению диагностики ЛГ при различных заболеваниях. Именно этим обусловлен особый интерес к данной междисциплинарной проблеме
