The Analysis of the COVID-19 Image Evolution in English Mass Media Discourse

Starting from January 2020, the whole world and all the people’s professional activities are affected by the COVID-19 pandemic. Since the beginning of the pandemic, the phenomenon of COVID has been analyzed from different perspectives. The present study aims to study the evolution of the COVID-19 image in the online mass media discourse on the example of the British Broadcasting Corporation (BBC) news portal. The research employs semantic network analysis to trace the changes in the description of the coronavirus-related articles presented online. Three samples of articles from the period from 2020 to 2022 are randomly collected and subjected to further analysis. As a result, the author concludes, that the image of the COVID pandemic has undergone a significant change from the distant public health-related phenomenon to one of the legal actors and social activities. The present study contributes to the analysis of the coronavirus pandemic domain in the online mass media discourse and diversifies the studies, employing the semantic network analysis approach

Polynomial reconstruction of electric charge distribution on the conductive plate caused by external electric field

The paper proposes an original method of calculating the charge distribution on the surface of the conductive plate introduced into the external electrostatic field. The authors managed to obtain the polynomials which allow to solve the integral equation that establishes the relationship between charge distribution of the conductive plate and the potential distribution of the external field and the potential on the surface of the plate. The proposed algorithms solutions are valid in the presence of axial symmetry of the field and the plate. Examples of calculation of conductor charge distribution in the presence of external field by using a polynomial expansion have been presented. The comparisons of results calculated by the polynomial method and by known analytical solutions have been given

Fluid Intelligence Test Scores Across the Schooling: Evidence of Nonlinear Changes in Girls and Boys

We are incredibly grateful for all participants for their contribution to the study. We thank Tatiana Bykovskaya and Olga Kashubina for their technical support.Received 26 April 2022. Accepted 17 August 2022. Published online 10 October 2022.The results of the analyses of the changes of fluid intelligence scores measured by the Standard Progressive Matrices test across all school years were presented. Sex differences in fluid intelligence scores for each year of schooling as well as in fluid intelligence changes across schooling were analyzed. A total of 1581 participants (51.1% boys) aged 6.8 to 19.1 years from one public school were involved in this cross-sectional study, of whom 871 were primary schoolchildren (mean age = 9.23; range 6.8–11.6), 507 were secondary schoolchildren (mean age = 14.06; range 10.8–18.0), and 203 were high schoolchildren (mean age = 17.25; range 15.3–19.1). To examine the changes in fluid intelligence both correlation analysis and polynomial regression of the total, boys’ and girls’ samples were performed. Linear, quadratic, and cubic regression models were fitted to the data. To explore sex differences in fluid intelligence in each year of schooling, the series of ANOVA were carried out. The results revealed that the school-age change in fluid intelligence is nonlinear for both girls and boys. The changes for girls during the schooling are best described by a quadratic relationship while those for boys are best reflected by a cubic relationship.This work was supported by the Russian Science Foundation under Grant number 17-78-30028

Blended Educational Technologies in Higher Education: Systematic Review of Domestic Publications

The article presents the results of generalization and systematization of scientific and practical information on the variety of types of blended educational technologies used in Russian higher education institutions. This specific product of digitalization causes the greatest interest of researchers and practitioners in the field of education. This systematic review is based on national scientific publications related to the development and practical implementation of educational technologies in higher education. The authors have analyzed 180 papers published between 2016 and 2021 in peer-reviewed scientific journals approved by the Higher Attestation Commission. Methods of qualitative and quantitative content analysis, systems analysis and contextological analysis, as well as analytical grouping, have been used.Content analysis of publications showed that the main property of blended educational technologies is their variability, which manifests itself through the described system of indicators. However, the structural organization of blended educational technologies models remains the most debatable issue among researches.The authors have identified and described the main directions in the development of the theory and practical application of blended educational technologies, namely: the formation of the structure and boundaries of the conceptual and terminological field; elaboration of the methodological basis of blended education development and definition of theoretical basis for changing traditional learning systems by designing a learning process based on the mechanisms of pedagogical and digital technologies integration.It has been established that the empirical studies with the elements of experimental work focused on defining the most effective combinations of traditional and digital educational technologies dominate in the national scientific community. The most popular methods of such integration include rotation of forms and types of learning activity in traditional and digital learning environments, integration of digital and traditional educational technologies based on the Moodle learning management system, as well as inclusion of separate forms and means of e-learning in the educational process

COLON CAPSULE ENDOSCOPY: POSSIBILITIES OF NON-INVASIVE DIAGNOSTICS OF COLON DISEASES

Purpose. Evaluation of feasibility of colon capsule endoscopy (CCE), as non-invasive method of diagnostics of colon abnormalities.Patients and methods. From 31.01.2014 to 10.01.2017 we successfully performed 100 CCE in 101 (99,0%) patients (m-50, f-48, mean age 44,7 ± 14,8 years, range 22–81), including 2 twins aged 8 years (CCE was performed with pediatrician). The main indication for colonoscopy was colorectal cancer screening (73 (73,0%) pts). The indication for colonoscopy to 2 twins was complicated Peutz Jeghers syndrome in one of them. CCE was performed using the system PillCam (Given Imaging) and capsule PillCam Colon 2. For the bowel preparation we used two-stage regimen; for the evaluation of preparation — J.A. Leighton scale.Results. Preparation was adequate in 88 (88,0%) pts, non-adequate — in 12 (12,0%) pts. Total CCE was performed in 82 (82,0%) patients. The mean colon transit time was 4 hours 43 min ± 3 hours15 min. Total evaluation of the colon was performed in 82 (82,0%) pts. Mucosal lesions were revealed in 75 (75,0%) pts, including epithelial polyps in 52 (69,3%) pts. We also revealed comorbid lesions in 41 (54,6%) pts. Colonoscopy after CCE was recommended to 28 (37,3%) pts because of polyp detection, sized ≥6 mm, and because of inflammatory changes of colon mucosa, but only 11 (39,3%) pts were performed colonoscopy.Conclusion. In this article the experience of colon capsule endoscopy demonstrates the principal possibility of noninvasive evaluation of the colon and detection of colon abnormalities

Supernovae - Optical Precursors of Short Gamma-Ray Bursts

The probability of observing "supernova - gamma-ray burst" (GRB) pair events and recurrent GRBs from one galaxy in a time interval of several years has been estimated. Supernova explosions in binary systems accompanied by the formation of a short-lived pair of compact objects can be the sources of such events. If a short GRB is generated during the collision of a pair, then approximately each of ~300 short GRBs with redshift z must have an optical precursor - a supernova in the observer's time interval <2(1+z)yr. If the supernova explosion has the pattern of a hypernova, then a successive observation of long and short GRBs is possible. The scenario for the generation of multiple GRBs in collapsing galactic nuclei is also discussed.Comment: 12 pages, 1 figure; this paper has the e-precursor arXiv:1101.3298 [astro-ph.HE

Swift J164449.3+573451 event: generation in the collapsing star cluster?

We discuss the multiband energy release in a model of a collapsing galactic nucleus, and we try to interpret the unique super-long cosmic gamma-ray event Swift J164449.3+573451 (GRB 110328A by early classification) in this scenario. Neutron stars and stellar-mass black holes can form evolutionary a compact self-gravitating subsystem in the galactic center. Collisions and merges of these stellar remnants during an avalanche contraction and collapse of the cluster core can produce powerful events in different bands due to several mechanisms. Collisions of neutron stars and stellar-mass black holes can generate gamma-ray bursts (GRBs) similar to the ordinary models of short GRB origin. The bright peaks during the first two days may also be a consequence of multiple matter supply (due to matter release in the collisions) and accretion onto the forming supermassive black hole. Numerous smaller peaks and later quasi-steady radiation can arise from gravitational lensing, late accretion of gas onto the supermassive black hole, and from particle acceleration by shock waves. Even if this model will not reproduce exactly all the Swift J164449.3+573451 properties in future observations, such collapses of galactic nuclei can be available for detection in other events.Comment: 7 pages, replaced by the final versio
