Features of the Flow of Matter in the X-Ray Binary Her X-1
Authors: Karitskaya E. , Bochkarev N.
Published: February 2022

We consider a model of discrete ﬂow of matter in the X-ray binary Her X-1/HZHer developed by us in the late 80s of thelast century. It well explains many phenomena in this X-ray system, including peaks on optical light curves formed by theinteraction of discretely incident matter with the outer parts of the accretion disk, as a result of which blobs are formed.Based on the published light curves constructed on the basis of the richest photometric data, a phase diagram (Φ, Ψ) of theidentiﬁed possible peaks is constructed. It is concluded that the appearance of peaks on the orbital light curves in certainorbital phases, depending on the phase of the 35-day cycle, continues, and the mechanism of blob formation continuesto work at the present time. Observations on eROSITA conﬁrmed the existence of a corona around the accretion disk,predicted by us in the frame of this model.
Dynamics of magnetic flux tubes in accretion disks of Herbig Ae/Be stars
Authors: Khaibrakhmanov S. , Dudorov A.
Published: February 2022

The dynamics of magnetic ﬂux tubes (MFTs) in accretion disks of Herbig Ae/Be stars with fossil large-scale magnetic ﬁeldis modeled. The model takes into account the buoyant force, turbulent and aerodynamic drag, radiative heat exchange withthe surrounding gas, and the magnetic ﬁeld of the disk. The structure of the disk is calculated using our MHD model,taking into account the heating of the surface layers of the disk with the intense stellar radiation. The simulations showthat MFTs periodically rise from the disk with speeds of 10 − 12 km s −1 and form an outﬂowing magnetized corona of thedisk. MFTs can experience magnetic oscillations under the action of the external magnetic ﬁeld near the disk’s surface. Weargue that the oscillations can produce observed IR-variability of Herbig Ae/Be stars, which would be more intense thanin the case of T Tauri stars, since the disks of Herbig Ae/Be stars are hotter, denser and have stronger magnetic ﬁeld.

Published: February 2022

We report the discovery of 4 new H 2 jets in Mon R1 star-forming region on the images obtained with the 2.5-m telescopeof the Caucasian Mountain Observatory of SAI MSU through the ﬁlter, centered on the H 2 1–0 S(1) emission line. Thisdiscovery conﬁrms the nature of these ﬂows, which existence was previously suspected using archival Spitzer GLIMPSE360and WISE survey images. Also two infrared reﬂection nebulae were revealed. On the Herschel PACS survey images we founda small group of far-infrared sources, mostly new ones. Among them are the possible exciting objects of these outﬂows.Spectral energy distributions of new sources show their extremely red colour and the bolometric luminosities reaching 3L ⊙and even 10L ⊙ . Several of them should belong to Class I and even to Class 0 objects.

Authors: Malofeev V.M. , Malov I.F. , Malov O.I. , Teplykh D.A.
Published: February 2022

Results of long time observations of the pulsar B0950+08 are given. These observations were carried out at the LPA radiotelescope at the frequency of 111 MHz from January of 2016 to May of 2019 (450 days). A strong variability in emission ofthis pulsar has been detected with changes of signal to noise ratios hundreds of times. In addition to the main pulse (MP)and interpulse (IP), this pulsar has “the bridge” and “the precursor” (Pr) located between MP and IP [1]. We detected theunusual IP and Pr radiation on August 1, 2017. On the base of strong 65 interpulses we found the correlations betweenenergies of IP and Pr and between the phase of IP and the distance Pr-IP. It is shown that the observed peculiarities ofthis pulsar can be explained in the frame of the aligned rotator model.

Authors: Sosnovskij A.A. , Pavlenko E.P.
Published: February 2022

The analysis of the white dwarf pulsations of the dwarf nova EZ Lyn (which outbursted in 2010) in 2015–2020 years basedon photometry at 2.6-m Shajn telescope of the Crimean Astrophysical Observatory is presented. It revealed an increasein the period of pulsations from 234 to 756 sec. In accordance with the empirical relationship between the period of thepulsations and the temperature of the white dwarf, this means a fast cooling of the white dwarf after the 2010 outburst.

Authors: Atapin K. , Vinokurov A. , Solovyeva Yu. , Fabrika S.
Published: February 2022

We report the discovery of a cyclotron resonant scattering feature (CRSF) in the ultraluminous X-ray source (ULX)NGC5474 X-1 that makes it the third ULX with a CRSF. Cyclotron lines arise in strong magnetic ﬁelds, which requiresthe object to be a neutron star. The line energy of 7.5 keV corresponds to the magnetic ﬁeld strength ∼ 10 12 G. The sourceshows a hard X-ray spectrum with Γ ∼ 1 and strong X-ray variability which is also typical for neutron star ULXs. In theoptical range, the object is interesting by the fact that it is projected onto an old stellar cluster (or located inside) with anage of about 1 Gyr.

Authors: Kaminker A.D. , Yakovlev D.G. , Potekhin A.Y. , Haensel P.
Published: February 2022

A simple model is presented of heat diﬀusion after a superburst in deep layers of the outer crust of an accreting neutronstar (10 7 . ρ . 4 × 10 11 g cm −3 ). Since the warm outer crust (T ∼ 10 8 − 10 9 K) has large heat capacity and acts as a heatreservoir, it is able to keep the outburst energy for months. The basic features of thermal afterburst evolution are outlined.They can be useful for interpreting observations of superbursts in low-mass X-ray binaries.

Solar-terrestrial relations: solar activity and the COVID-19 pandemic
Authors: Ragulskaya M. , Tekutskaya E.
Published: February 2022

COVID-19 pandemic took the start at the lows of the 11-year and quasi-century solar cycle. The genogeographic character-istics of the population have become one of the signiﬁcant factors determining the development of the local epidemics. Thelargest number of victims per 1 million inhabitants is recorded in the territories with a dominant haplogroup R1b: Italy,Spain, France, Belgium, Great Britain, and the United States. The R1a haplogroup is characterized by the rapid develop-ment of the COVID-19 pandemic with low mortality and a large number of asymptomatic patients (Russia, Germany, andIran). The level of herd immunity achieved through vaccination also depends on the genetic makeup of the population andsolar activity. Its value is highest for countries with a dominant haplogroup R1b (about 80% for haplogroup R1b versus40% for haplogroup N). The resulting eﬀect can be associated with the generation of reactive oxygen species and aﬀectedhuman adaptive capabilities.
Peculiar velocities of SNe Ia in clusters of galaxies
Authors: Balakina E. , Pruzhinskaya M.
Published: February 2022

The study of the accelerating expansion of the Universe is possible because of the standardization procedure of Type IaSupernovae (SNe). However, we still observe the residual dispersion on the Hubble diagram that could be related toenvironmental eﬀects and unknown peculiar velocities of SNe Ia. In this analysis, we continue to study the peculiar velocitiesof SNe inside galaxy clusters and their inﬂuence on distance modulus measurements. We perform the ﬁt for a low redshiftz ≤ 0.15 sample with a ﬁxed value of Ω m for C11 and G10 models and calculate wRM S value to estimate the impactof peculiar velocity eﬀect. We get the wRM S = 0.1643 for the C11 sample with SNe Ia in clusters if we use the galaxycluster z cl instead of the host galaxy z host , wRM S = 0.1696 in the original data (for G10 wRM S = 0.1617 and wRM S =0.1643, respectively). The results show the decreasing of residual dispersion on the Hubble diagram. Therefore, this eﬀectis considerable for supernovae in clusters and should be taken into account in future cosmological analyses.

Published: February 2022

For a large sample of groups/clusters of galaxies (N =185), we obtained the scaling relations among of their photometricaland dynamical parameters. We ﬁnd:0.77±0.011. that in the virialized regions of the galaxy systems the total luminosity increase with mass L K ∝ M 200(M K <−21. m 0);2. that the new halo boundary of the galaxy systems corresponds to the splashback radius R sp . These radius is deﬁnedby the observed intergrated distribution of the number of galaxies as a function of the angular distance from thegroup/cluster center squared;3. that the fraction of galaxies with quenched star formation is maximal in the central regions of the galaxy systems,and it decreases to the radius R sp , but remains higher than in the ﬁeld on ∼ 27%.

Published: February 2022

We present the results of pilot observations of the OH megamaser (OHM) sample carried out with the radio telescopeRATAN-600 at 1.2, 2.3, 4.7, 8.2, 11.2, and 22.3 GHz in 2019–2021. When comparing the radio continuum properties ofthe OHM sample and the control sample of galaxies without detected maser emission, we determine the median spectralindex at 4.7 GHz α 4.7 = −0.59 for the OHM sample, and α 4.7 = −0.71 for the non-OHM galaxies, and steep radiospectra prevail in both samples. Subsamples of OHMs powered by active galactic nuclei (AGN) and star formation have nosigniﬁcant diﬀerences in their radio properties. AGN-powered galaxies exhibit larger scatter in a range of parameters andtheir standard deviations.
Superluminous quasars and mesolensing
Authors: Raikov A. , Lovyagin N. , Yershov V.
Published: February 2022

Observed magnitudes of many quasars with redshifts exceeding z = 5 correspond to luminosities L bol > 10 14 L ⊙ . Thestandard mechanism of quasar energy release by accretion suggests that masses of superluminous quasars should exceed10 10 M ⊙ . On the other hand, the age of these objects in the standard cosmological model is below one billion years, whichis too short to explain their formation in the early Universe. Many quasars are known to be gravitationally lensed; showingmultiple images of the same object. In the case of remote quasars with no multiple images, it is still possible that they arealso gravitationally lensed by foreground objects of intermediate masses, such as globular clusters or dwarf galaxies. Suchmesolensing would result in essential ampliﬁcation of quasar brightnesses, subject to geometrical conﬁguration betweenthe lens and the lensed object. Here we estimate the fraction of quasars whose brightness might have been ampliﬁed bygravitational lensing.
Grey intergalactic dust could explain the Hubble constant tension
Authors: Yershov V. , Raikov A. , Lovyagin N. , Kuin P. , Popova E.
Published: February 2022

It is possible to explain the discrepancy (tension) between the local measurement of the cosmological parameter H 0 (theHubble constant) and its value derived from the Planck-mission measurements of the Cosmic Microwave Background (CMB)by considering contamination of the CMB by emission from some medium surrounding distant extragalactic sources, such asextremely cold coarse-grain (grey) dust. Though being distant, such a medium would still be in the foreground with respectto the CMB, and, as any other foreground, it would alter the CMB power spectrum. This could contribute to the dispersionof CMB temperature ﬂuctuations. By generating random samples of CMB with diﬀerent dispersions, we have checked thatthe increased dispersion leads to a smaller estimated value of H 0 , the rest of the cosmological model parameters remainingﬁxed. This might explain the reduced value of the Planck-derived parameter H 0 with respect to the local measurements.

The eﬀect of processes p + e − → n + ν e and µ + → e + + ν̃ µ + ν e on relic neutrino distribution function in the region ofsmall coordinate momentums is studied. The Boltzmann kinetic equation on the electron neutrino distribution function issolved in this region at temperatures above 10 MeV taking into account generation of electron neutrinos due to the aboveprocesses in the assumption that at these temperatures neutrinos of larger momentums are thermalized instantaneously.The eﬀect of thermalization of neutrinos due to their scattering on electrons and positrons on the distribution function inthis region at temperatures lesser than 10 MeV is examined.

Published: February 2022

The results of new spectral and photometric observations of the poorly studied S-star CSS 1102 are presented. Accordingto the analysis of spectra, CSS 1102 was classiﬁed as a symbiotic star. We observed HI, HeI and [NeIII] emission linesin both spectra of the star. The absorption spectrum demonstrates the prominent molecular bands of TiO, ZrO andYO. The system consists of a cold component that is a zirconium star of spectral type S4.5/2, a hot component with40000 K < T hot < 55000 K, and a nebula. Photometric monitorings in the B band showed the existence of a ﬂickeringeﬀect with diﬀerent periods in CSS 1102. This variability may be associated with emission of an accretion disk in CSS 1102system.

Authors:   , Sentsomedi Keamogetse Refilwe
Published: February 2022

Introduction: Participation of young females in soccer has started to increase in the past few years. Females participating in soccer are more vulnerable to injuries than males due to the nature of the sport especially because the sport is characterised as a vigorous, high intensity, intermittent ball and contact activity. Objective: This study sought to determine the epidemiology of injuries in high school female soccer players in the eThekwini district. Method: A quantitative approach using a cross sectional survey was used to determine the epidemiology of injuries in female high school soccer players in the eThekwini district. One-hundred-and-ninety-seven female high school soccer players, between the ages of 14 to 19 years who have played soccer for at least one season, from 27 female high schools in the eThekwini district were invited to participate. A self-administered questionnaire was used to determine the demographic profile of the players and the reported prevalence of injuries in the soccer players. The study also determined the profile of soccer related injuries, management of injuries, identified risk factors for injury, and compared injuries occurring during training and during matches. Results: Out of a total of 85 respondents only 31 sustained injuries. The injury prevalence for the season was 36.5%. Only 61 injuries (71.8%) were reported by the injured players. The rate of injury was 90 per 1000 athlete exposure hours during the season. Only two female players reported the five injuries while all 29 female players sustained at least one injury. The defenders (31.7%) and midfielders (28.6%) sustained the most injuries. Most injuries reported were contact in nature (12.9%). More injuries occurred during training (12.9%) rather than during matches (8.2%). The lower extremity (77.8%) was injured more than the upper extremity (22.2%). The knee (22.2%) and ankle (15.9%) were the most frequently injured body parts. Muscle injury (23.5%) was the most commonly reported followed by bruising (10.6%). Conclusion: Prevalence of injuries was high in the cohort studied. The lower limb, specifically the knee and ankle were most commonly injured. Muscle injury and bruising were the most common injury affecting the lower extremity. It is recommended that the study be extended to a larger cohort of school children.
The effectiveness of lower thoracic spinal manipulation on lumbar extensor muscle endurance and range of motion in asymptomatic males : a placebo controlled study
Authors:   , Matsebula Lindelwe
Published: February 2022

Background: Spinal manipulative therapy (SMT) is a commonly used treatment for many musculoskeletal conditions although the exact mechanism explaining its effectiveness is not well understood. Several studies have investigated the effect of SMT on the paraspinal muscles where neuromuscular effects have been observed, however few studies have assessed whether these changes result in a change in the functioning of the paraspinal muscles. This study aimed to determine the effect of lower thoracic spinal manipulation compared to a placebo intervention on lumbar extensor muscle endurance in asymptomatic participants. Methodology: This was a quantitative, pre-test post-test, placebo controlled trial involving 40 male participants between the ages of 20 and 40 years. The participants were randomly allocated to either the lower thoracic spinal manipulation group or a placebo group. Manipulation was delivered using the Impulse Adjusting Instrument®. Objective measures included lumbar spinal range of motion, a paraspinal muscle endurance test, and surface electromyography readings. Subjective measures were the verbalisation of pain and/or discomfort during the paraspinal muscle endurance test. IBM® SPSS® statistics version 21 and STATA 11 were used to analyse the data. A p-value of <0.05 was considered statistically significant. Results: There were no statistically significant differences between the groups in terms of subjective and objective measurements. A trend of treatment effect was observed for paraspinal muscle endurance where the intervention group showed noticeable improvements in endurance scores. Conclusion: Further studies need to be conducted to determine if the trends observed would occur in a larger study population.
Causes and effect of student nurses absenteeism at the KwaZulu-Natal College of Nursing
Authors:   , Singh Pratima
Published: February 2022

INTRODUCTION A four-year diploma nursing programme undertaken by the KwaZulu-Natal College of Nursing provides training to students to become professional nurses. However, it has been noted that absenteeism of student nurses enrolled in this programme has increased. Absenteeism could result in demotion, extension of training or termination of students from the programme. This would result in fewer student nurses completing training and therefore a shortage of professional nurses. AIM OF THE STUDY The aim of the study was to determine the causes and effects of absenteeism amongst student nurses that are currently registered for a four-year diploma programme (R425) in the KwaZulu-Natal College of Nursing (KZNCN). METHODOLOGY A quantitative method was used, which comprised two phases, namely, data collection through the use of a self-administered questionnaire and a retrospective record review. Simple random sampling was used to select students from the peri-urban Midlands and rural uGu districts. Stratified random sampling of 301 student nurses at different levels of training from the three campuses was done. A total of 301 questionnaires were distributed to participants; all were returned, resulting in a 100% response rate. During a retrospective record review student records were examined to assess clinical and theoretical performance of students. Statistical analysis was done using the SPSS version 22.0. RESULTS The results of the study revealed that students experienced problems in the clinical/practical areas that resulted in them absenting themselves. There were 14 terminations of training due to absenteeism. Student nurses who did not absent themselves obtained entry to the examination, whilst students with excessive absenteeism did not obtain entry to the examination.
Occupational stressors in diagnostic radiographers working in public health facilities in the eThekwini district of KwaZulu-Natal
Authors:   , Gam Nkululeko Phalson
Published: February 2022

Introduction Occupational stress has negative effects on both the organisation and individuals employed by the organisation. In the organisation it can result in high levels of absenteeism, reduced productivity and compromised levels of patient care. Furthermore individuals affected by stress may suffer from raised levels of tension, mental fatigue, insufficient sleep, anxiety, and anger. Interventions to prevent both organisational and individual effects of occupational stress may only be implemented once stressors in an occupa-tional group have been identified hence the need for the current study. Purpose The purpose of the study was to investigate occupational stress in diagnostic radiographers working in public healthcare institutions in the eThekwini District of KwaZulu-Natal using a quantitative research approach. Method A cross sectional survey using a validated questionnaire with some open and closed-ended questions was utilised. Radiographers working in public hospitals in the eThekwini District of KwaZulu-Natal were invited to parti-cipate in the study. Respondents were asked to answer 60 closed ended and four open ended questions. Open ended questions afforded the respondents an opportunity to express their opinions. Quantitative data was analysed using the Statistical Package for Social Sciences (SPSS) version 21.0. Inferential statistics included the use of reliability coefficients, correlations and chi square test at a 95% confidence level. Open ended questions were analysed using thematic analysis. Results One hundred and one questionnaires were administered and forty three were returned which resulted in a 43% response rate. The mean age of respondents was 31.7 years and 88.4% were females. The majority (67.4%) were in possession of a National Diploma in Radiography. Seventy two percent worked in regional hospitals. The majority (41.8%) were employed as chief radiographers. Most radiographers affected by stressors were those working in regional hospitals. The three main sources of stress in order of response were workload, faulty equipment and staff shortages. In addition, bullying, long and strenuous shifts as well as training of students were also found to be stressors. Physical exercises, counselling and wellness days were used to reduce stress whilst employment of more staff, attending to faulty equipment, team building, reducing workload, and improved working conditions were suggested as methods of reducing stress amongst radiographers. Conclusion Radiographers working in the eThekwini District were stressed by a number of factors in their work places. Radiographers suggested ways that can be employed to reduce stress in their departments. A close cooperation between radiographers; radiography supervisors; institutional, district and provincial managers is recommended in order to address the challenges faced by radiographers.
The association between acute childhood diarrhoea and diarrhoeagenic E.coli present in contaminated soil in informal settlements in Durban
Authors:   , Ramlal Preshod Sewnand
Published: February 2022

In South Africa, under-five childhood morbidity and mortality rates have increased due to diarrhoea with acute diarrhoea posing a major public health threat especially, in informal settlements. Therefore this study sought to, a) investigate community knowledge, attitudes, behaviour and practices (KABP) regarding domestic waste and childhood diarrhoeal management, b) to enumerate and identify diarrhoeagenic E.coli species from soil samples extracted from open waste dump sites and c) to investigate any association(s) with diarrhoeagenic E.coli and potential risk of contracting diarrhoea. This two-phased cross-sectional study in six informal settlements in the greater Durban area constituted, respectively, of the administering of questionnaires to 360 primary caregivers and; sampling the prevalence of diarrhoeagenic E.coli (DEC) in waste dumps using quantitative polymerase chain reaction methodologies. Relationships between socio-demographic and educational status to determine potential household risk factors towards under-five diarrhoea prevalence were assessed. The KABP results identified domestic waste and greywater disposal, mother and child method of sanitation, personal and domestic hygiene practices and mechanical vectors as significant contributory risk factors. Of concern is that more than 80% of under-five children played in or near faecally-contaminated waste dump sites. The recovery of four DEC pathotypes including enterohaemorrhagic E.coli, enteropathogenic E.coli, enterotoxigenic E.coli and enteroaggregative E.coli suggest that its persistence in waste-dump soil has the ability to cause under-five diarrhoea in both sporadic and endemic settings. This commonly transmitted hand-to-mouth illness will necessitate and place huge demands on the primary catalysts of change i.e. local governmental role players and caregivers. These change agents have to ensure highly consistent levels of domestic and personal hygiene and implement feasible reduction strategies to waste-dump exposure of diarrhoeal-causing pathogens, particularly among under-five children living in Durban’s informal settlements.
The effect of sacroiliac joint manipulation on gluteus maximus muscle activity in asymptomatic participants
Authors:   , Worth Kevin
Published: February 2022

The effects of spinal manipulation are well documented; however there is a gap in the current literature regarding the exact mechanisms underlying the effectiveness of spinal manipulation. Further evidence is required to improve the understanding of the neurophysiological effects of spinal manipulative therapy and its effect on muscle activity. The objectives of this study were to investigate the effects of sacroiliac joint manipulation on gluteus maximus muscle activity in an asymptomatic sample group when compared to a placebo group Methods: A randomized, controlled, pre-test, post-test repeated measures design allowed for 28 participants, aged 18-40 years old, with sacroiliac joint dysfunction to be allocated into either a sacroiliac joint manipulation or a placebo group. Muscle activity of the gluteus maximus was measured before intervention and again 10 minutes post intervention. IBM SPSS was used to analyse the data with significance set at (p=0.05). Repeated measures ANOVA testing was used to determine the significance within and between groups. Results: There was evidence of an improvement in the intervention compared with the placebo group from pre to post for outcomes of Channel A mean and maximum values, and for Channel B maximum values. In the other measures there was a trend observed but insufficient evidence to conclude that it was a real effect. The partial eta squared values were relatively small for these non-significant effects and medium to large for the significant effects. Conclusion: Analysis of the results revealed that there was evidence of an improvement in the intervention group when compared with the placebo group in some of the outcomes measured while other outcomes measured trended towards an improvement but lacked a sufficiently large sample size to conclude that it was a statistically significant effect.

У цій роботі узагальнено аргументи та контраргументи в рамках наукової дискусії щодо тлумачення поняття «сталий розвиток» в українських політичних документах, що ґрунтується на розумінні цього поняття в політичних колах, його перекладі з англійської мови українською, наданні йому власного значення, яке не завжди відображає результати наукових досліджень. Основною метою дослідження є розгляд поняття «сталий розвиток», розуміння його значення в діяльності урядів, досвід яких запроваджується в Україні, та порівняння з українською науковою думкою та практикою. Різниця в трактуванні цього поняття призводить до розбіжностей у практичній реалізації сталого розвитку, зокрема в залученні населення, побудові партнерських стосунків та комунікацій та використанні сучасних можливостей електронного урядування. Актуальність вирішення наукової проблеми полягає в тому, що вузьке розуміння сталого розвитку в українській науці та практиці призводить до неможливості повного впровадження досвіду зарубіжних країн, відсутності державних стратегічних документів зі сталого розвитку та інформаційного розриву між Україною та іншими країнами. Період дослідження – 2017–2020 роки. Об’єктом дослідження є добровільні національні огляди країн, досвід яких впроваджується в Україні. Дослідження емпірично підтверджує та теоретично доводить, що в українській науці, зокрема в державному управлінні та політиці, необхідно переоцінити науково-прикладні підходи до сталого розвитку та розробити нові напрями досліджень, які можна застосувати в практиці державного управління. Наявна багатозначність поняття «сталий розвиток» викликає когнітивний дисонанс, що веде до відсутності чіткої стратегії та цілей сталого розвитку, постійної зміни його векторів сталого розвитку.

Статтю присвячено актуальній науковій проблемі впровадження політики ревіталізації міст в Україні. Особливу увагу приділено належному правовому регулюванню окресленої проблеми та ролі органів публічної влади в імплементації політики ревіталізації. Визначено, що поняття «ревіталізація» розуміють як комплексний процес подолання просторових, економічних, соціальних, культурних, екологічних кризових явищ функціонування деградованих міських територій і створення передумов для їхнього сталого розвитку. Проаналізовано зарубіжний досвід упровадження політики відновлення деградованих територій міст таких країн, як Велика Британія, Франція, Німеччина, Сполучені Штати Америки та інших. На основі проведеного аналізу виокремлено певні особливості. Зокрема підкреслено, що Сполучені Штати Америки використовують фінансові інструменти і субсидіюють території задля покращення життя. Водночас інколи ревіталізація може стосуватися лише окремих районів, а не міста загалом. Визначено, що внаслідок політики ревіталізації у Великій Британії і Франції вдалося подолати низку кризових явищ, а досвід Німеччини дозволяє стверджувати, що інструменти громадської партисипації є ефективними. Проаналізовано прогалини на шляху до ревіталізації українських міст, серед яких є недофінансування, слабка інформаційна політика та низький рівень обізнаності на місцях, а також відсутність комплексної програми розвитку міст. У висновках розроблено рекомендації щодо впровадження політики ревіталізації міст в Україні. Запропоновано створення відповідних інституцій, залучення партнерської підтримки бізнесу, громадськості та органів місцевого самоврядування до розроблення нормативно-правової бази і програми ревіталізацї.

У статті висвітлено особливості державного управління у сфері кібербезпеки Іспанії. Із початком пандемії у світі значно збільшилася кількість кібератак як на державні, так і на приватні структури. Тому гарантування і забезпечення безпеки у кіберпросторі стало одним із стратегічних пріоритетів розвинених країн через його безпосередній вплив на національну безпеку, на конкурентоспроможність компаній і на процвітання суспільства загалом. Значних успіхів у розробленні власної системи Національної кібербезпеки досягла Іспанія. Ця система, очолювана головою уряду, сформована із трьох органів: Ради національної безпеки (Consejo de Seguridad Nacional) як делегованої комісії уряду з національної безпеки; Національної ради із кібербезпеки (Consejo Nacional de Ciberseguridad), що є складовою частиною Ради національної безпеки, допомагаючи голові уряду спрямовувати і координувати політику національної безпеки у сфері інформаційної безпеки, а також сприяючи координації, співпраці між державними адміністраціями, між ними та приватним сектором; Ситуаційного комітету (El Comité de Situación), який за підтримки Департаменту внутрішньої безпеки підтримує управління кризовими ситуаціями у будь-якій сфері, які через свою масштабність перевищують можливості застосування звичайних механізмів. Окреме місце у забезпеченні безпеки у кіберпросторі Іспанії посідає Національний криптологічний центр, що підпорядковується Національному розвідувальному центру при Міністерстві оборони. Починаючи із 2013 року, в Іспанії один раз у декілька років ухвалюється Національна стратегія із кібербезпеки. Досвід цієї держави засвідчив успішність заходів, що впроваджуються. Підтвердженням цього є те, що глобальний індекс кібербезпеки, підготовлений Міжнародним союзом телекомунікацій Організації Об’єднаних Націй, ставить Іспанію на 7-ме місце у світі.

The Stoicism of the Lone Wolf. The Romantic Aesthetics of Alfred de Vigny and Its Literary Outlines. Part One
Authors:   Russian Academy of Sciences, Mankovskaya N.B.
Published: February 2022

The article reveals the specific nature of Alfred de Vigny’s aesthetic views and literary work which illustrates his original position in the context of the aesthetics of French romanticism. Alfred de Vigny shared its basic principles related to the conviction in the inherent value of art, the priority of artistic perfection, idealization and symbolization, and an increased interest in the national origins of artistic creativity and the character of a romantic hero — sensitive, passionate, melancholic, and at the same time egocentric. However, he gave them the romantic-heroic connotation of the philosophy of stoicism, which defined the semantic dominant of his creative work and the aura of masculine restraint inherent in it. His reflections on the truth and fiction in art, artistic images and symbols, the features of a historical novel, the character of a romantic drama, and the figure of a banished poet largely paved the way for the further development of these subjects both in theory and artistic practice. Most of the characters of his symbolic plays, novels, and poems are self-absorbed, proud loners, marked by a tragic worldview, who stoically endure the adversities that fall to their lot but are unable to avoid fatal outcomes. Alfred de Vigny considered himself an “epic moralist” focused on issues of honor, duty, and conscience. Another distinctive feature of his position is not only the interest in national history but also a direct appeal to its vicissitudes in his artistic creativity, as well as conceptualization of ways to understand history in art. The rich symbolism of de Vigny’s works, their high artistry, a deep understanding of the tragic fate of the artist, a cursed poet, had a significant impact on the aesthetics and poetics of symbolism. Additionally, Alfred de Vigny’s philosophical and aesthetic ideas of abandonment of man into existence, the tragic nature of his lot, hopeless loneliness, inescapable longing, and despair, which were reflected in the pessimistic tone of many of his works, had a considerable influence on the creative activity of French existentialists and their followers in the 20th–21st centuries.
Semantic Metamorphoses of The Scarlet Sails Festival
Authors:   Saint Petersburg State Institute of Culture, Slesar E.A.
Published: February 2022

The USSR staging practices, which passed into and later took roots in the post-Soviet Russian performance culture, accelerated the processes of mass culture sovietization and paved the way for the development of the utopian motives inherent in the official performative practices. This research is relevant, since the study of the properties of semantic lability of the Soviet performance forms makes it possible to clarify the functionality and cultural significance of contemporary mass performances. The Scarlet Sails Festival was chosen as a study material, since it is a sample of the Soviet performance that has been successfully integrated into the post-Soviet calendar of festivals. This paper is focused on the issue of semantic distortion of the plot and character schemes of A. Grin’s (1880–1932) fairy tale The Scarlet Sails (1922) in the context of the Soviet mass theatrical performance of the same name: The Scarlet Sails Festival (1970, directed by A. Orleansky; 1972, directed by I. Rakhlin). This research aims to analyze the semantic shifts in The Scarlet Sails theatrical performances (1970, 1972) in its dialogic connection with the literary original. The scientific problem of the paper is to reveal the mechanisms and forms of integrating the Soviet indoctrinal discourse into the texture of the theatrical performance. The reconstruction based on the archive materials shows a steady deviation from A. Grin’s original narrative towards the dominating Soviet myth. The author concludes that the principles of duplication and montage underlying the performance resulted in semantic distortion of the priority character, events, and motives. The analysis of the artistic structures of the performance reveals that the original was converted by means of generating analogous artistic forms and artificial semantic convergence that is characterized by forced superimposition of acoustic and visual quotations and ideologemes of the Soviet mass culture on A. Grin’s story. This research reveals heterogeneous elements of the performance (e.g. vows, ancestor worship, narrative of threats), which articulated the relevant axiological agenda. This research is based on the methods of reconstruction and description of the phenomena of the Soviet official performance culture within Herrmann and Gvozdev’s (Leningrad, St. Petersburg) school of theatre studies.
The Dialogue of Art and Philosophy in Masaccio’s Holy Trinity and G. Palestrina’s Agnus Dei
Authors:   Glinka Nizhny Novgorod State Conservatoire, Bragina N.N.
Published: February 2022

The article is based on the analysis of two Renaissance works of art: Masaccio’s Holy Trinity and G. Palestrina’s Agnus Dei, which illustrate how works of art reflect the philosophy of the epoch. The author of the article draws a parallel between the nature of secular and religious Renaissance art and reveals their traditional and innovative features. The relevance of the research is due to the increased interest in the interdisciplinary scientific approach and a low number of hermeneutical studies available that reveal the common semantics of works of different art forms. Masaccio’s Holy Trinity accentuates symbolic elements characteristic of medieval art and the realistic features reflecting the trends of the Modern Era. The semantics of the painting is studied through the analysis of its structure, which presents the geometry of a triangle and a circle in their traditional philosophical interpretation. Similar methods of composition are revealed in the motet Agnus Dei by G. Palestrina. Since the motet is part of a mass dedicated to the Virgin Mary, the image of the Trinity is conveyed as if through contemplation of the Mother of God. Although there is no mention of Madonna in the traditional Latin text of Agnus Dei, her presence is indicated in the main motif of the motet. Its three-part form is associated with the symbolism of the Trinity, and each part of the work corresponds to one of Its hypostases. The findings suggest that in the works of painting and music one can trace the artistic representation of the basic philosophical ideas of the Italian Renaissance (e.g. anthropocentrism, the Trinity concept, and general ideas about the structure of the universe). In addition, conclusions are made about the further evolution and transformation of these ideas in the Baroque era.
Theology In The Classroom
Authors: De Muynck Bram
Published: February 2022

Christian teachers do not naturally connect theology with their professional practice. This article explores the reasons for this, which all have to do with how theory functions in teaching. Theory will mainly come into focus when practical problems arise, but theological concepts are not the first to come into view. The article states that tensions that teachers experience in practice are triggers for theological reflection. This is in coherence with the call for Christians to test and discern what is the will of God (Rom. 12:2). Teachers are supposed to be able to reflect on three dimensions where tensions can be recognized. The first is the response to general cultural ideas. The second is the call for a collective theological vision in school teams. Finally, existential tensions find solutions in theological language. Prospective Christian teachers should have training in to reflect on those three levels.
