Authors: Vlasova O. V. , Denisova V. S. , Zakalashniy A. V. , Kulikova O. V.
Published: December 2023

The purpose of this work was developing of protective technological coating for protection of heat-resistant nickel alloy with single-crystal structure ZHS30 during high-temperature homogenization. Based on characteristics of the alloy the synthesis of coatings was carried out in following directions: modification of known coatings in the system CaO–BaO–SiO2 by introducting refractory filler and organosilicon materials, research of two-layer coatings and synthesis of refractory frits in various silicate systems.
The best properties of alloy ZHS30 are obtained using a coating based on a synthesized frit containing SiO2, B2O3, BaO, ZrO2. High efficiency of the protective action of the coating is ensured by the chemical composition of the frit which leads to the formation of structural groups [BO4] in the glass that participate in the formation of the glass lattice. Zirconium ions also participate in the construction of the structure and together with silicon and boron ions form a single boron-zirconium-silicon-oxygen framework of high degree of polymerization. The revealed liquation structure of the frit consists of two glass phases: the more easily low-melting matrix contains drop-like inhomogeneities distributed in it enriched of SiO2 which explains the steadiness and stability of the glass at operating temperatures.

Published: December 2023

The possibilities of obtaining metal-ceramic materials of the composition Al2O3–Al by liquid-phase oxidation of aluminum by purging the melt with oxygen are considered. The manufacturability of this process makes it possible to avoid the use of powder materials, which leads to a large variability in the formation of the phase components of the materials obtained and a reduction in the cost of their production in comparison with powder metallurgy methods. It is established that by regulating the oxidation process by changing the speed and supply of the gas mixture, it is possible to obtain metal-ceramic composites with different geometric configurations of the ceramic phase and its quantity. An algorithm is proposed for calculating the kinetics of aluminum oxidation during the production of the ceramic phase of a metal-ceramic composite, taking into account the peculiarities of the thermophysical process.

Published: December 2023

Based on glass in the SrO–Al2O3–P2O5–SiO2–F system, functional glass fillers for glass ionomer cements containing up to 13 wt. % fluorine were obtained. The high level of radiopacity of the filling material is due to the presence of the absorbing component of the glass filler - oxide and strontium fluoride, which are introduced into the glass together. The use of fusible fluorine-containing raw materials makes it possible to reduce the glass transition temperatures, which opens up prospects for the industrial development of the developed compositions at melting temperatures below 1500 °C. The value of the refractive index of glasses with a high fluorine content nD ~ 1.50 is more in line with the refractive index of the polymer matrix of glass ionomer cement, which ensures high aesthetic characteristics of the filling material. Samples of transparent filling glass ionomer cement with high compressive strength > 100 MPa and hardening time of 5 min were obtained.
SURFACE CHARGES AND ZERO CHARGE POINTS OF NATURAL CLAYS OF ORENBURG REGION
Authors: Kanygina O. N. , Kushnareva O. P. , Salnikova E. V. , Yudin A. A.
Published: December 2023

The values of surface charges and zero charge points in water-clay suspensions with pH equal to 5, 7 and 9 have been studied. Their changes under the influence of a microwave field and variations in particle dispersion have been determined.
Powders of two fractions of montmorillonite, polymineral and kaolin clays of the Orenburg region were selected as objects of research. The determination of the TNZ of natural clays was carried out by the method of weight titration, based on the measurement of the pH limit value with an increase in the weight fractions of clay. Processing of clay powders in a microwave field was carried out according to the following mode: output power of 750 watts, operating frequency of 2.45 GHz, exposure time 600 s. The magnitude and sign of the charges formed at the interface of the surface of the electrolyte solution particles depend on the mineralogical compositions of the particles.
The fine fractions of two clays – montmorillonite containing and polymineral – were sensitive to treatment in the microwave field; the pH values of TNZ shifted to the acidic region by 0.26 and 0.31 units, respectively (by 4 %). The pH values of the TNZ suspensions with kaolin clay after treatment in microwave radiation practically did not change. If the pH value of the solution surrounding the particle exceeds the pH of the TNZ, then the sorbent will be able to absorb cations if the pH value of the solution is lower than the pH of the TNZ – anions.
The results obtained will allow the use of microwave exposure as a tool that expands the pH range, contributing to the effective sorption of anions and cations.
Magie, věda a historiografie vědy
Authors: Joseph Jacques
Published: December 2023

Studie si klade za cíl zmapovat proměny v chápání vztahů mezi magií a vědou v průběhu 20. století. Východiskem je pozitivistická představa, která z magie činí iracionální protipól vědy. Na příkladu Lynna Thorndika a Frances Yatesové pak článek ukazuje, jak byla v historickém bádání tato představa postupně nabourávána. Navzdory tomuto vývoji i postupné rehabilitaci studia dějin západního esoterismu koncem 20. století však dějiny magie zůstávají v akademickém prostředí poněkud problematickým tématem. Jako zástupce současných snah tuto situaci napravit je v závěru článku představen John Henry. V jeho pojetí jsou pojmy „magie“ a „vědy“ zbaveny jakéhokoli esencialismu a středem pozornosti se naopak stává komplexní síť interakcí, v jejímž rámci jsou v průběhu 16.–18. století sjednávány a promýšleny jejich hranice. Takovýto pohled na vztah magie a vědy v raném novověku pak zároveň ukazuje i to, jakým způsobem byly během tohoto konstruování disciplinárních hranic položeny základy i pro pozitivistickou představu radikální protikladnosti magie a vědy.
Revisiting life with Martin Heidegger
Authors: Zgórecki Przemysław
Published: December 2023

The purpose of this article is to trace the essential foundations of the reduction carried out by young Heidegger, whereby the most primordial experience of life emerges from religious experience. The considerations presented below consistently follow the path described above leading back to the thing itself, that is, precisely back to life itself. Hence, we will not be interested here simply in the religious thinking of the young Heidegger, nor in his relation to the problem of God. Instead, we will try to reconstruct his path back towards life itself. This article admittedly focuses on Heidegger’s early philosophical explorations. It seems, however, that Heidegger remains faithful to the very end to the ambitious goals set by the inconspicuous schema for the Kriegsnotsemester lecture of 1919, outlined with youthful enthusiasm for the search for real life. It is hard to resist the impression that the whole long path of his thinking is just such a constant return to life.
Проклитизација глаголских енклитика у дијалектима српског језика
Authors: Огњановић Сања П.
Published: December 2023

Као и за остале енклитике, и за распоређивање глаголских енклитика у српском језику постоје посебна позициона правила. Као најважније ограничење истиче се немогућност употребе енклитика у иницијалном положају, или иза везника и, а и ни. Ипак, у појединим дијалектима српског језика јављају се енклитике у иницијалном положају, када постају проклитике. У делубанатских и призренско‑тимочких говора проклитизација енклитика је позната особина, настала као резултат интерференције са суседним словенским и несловенским језицима. Увидом у грађу потврђује се и шири домет ове појаве, нпр. у косовско‑ресавском дијалекту, како на југу ареала, у северној Метохији, тако и на северу, у Браничевском округу. Проклитички употребљене енклитике су забележене и у говору источне Шумадије, као и у неким исељеничким српским говорима.
Rekcja a polisemia czasowników w gwarach polskich
Authors: Ejsmunt-Wieczorek Izabela
Published: December 2023

Artykuł poświęcono dwóm ważnym zagadnieniom: semantyce i składni werbalnej w gwarach polskich. Na zależności między tymi płaszczyznami języka zwracano już uwagę w opracowaniach historycznych i współczesnych. Bardzo trudno rozstrzygnąć, które czasowniki mają charakter polisemiczny, a które są jedynie wariantami semantycznymi tego samego leksemu. Próbowano zatem zbadać, w jakim stopniu kryterium syntaktyczne może okazać się przydatne w rozwiązaniu problemu polisemii werbalnej w gwarach, w których mamy do czynienia ze słownictwem ludowym, często uwikłanym w indywidualny kontekst zdaniowy i sytuacyjny. Analizie semantycznej i składniowej poddano czasowniki wieloznaczne zaczerpnięte ze słownika gwarowego Mieczysława Szymczaka.

Damage accumulation and failure mechanism of glass/epoxy composite laminates subjected to repeated low velocity impacts
Authors: Li Hao , Yu Zhaogang , Liu Kun , Tao Zhen , Zhang Jiangtao
Published: December 2023

In this work, the damage accumulation and failure mechanism of glass fiber-reinforced epoxy composite laminates under repeated low velocity impacts were studied considering the influence of stacking sequence. The typical sandwich-like [0°2/90°2]s, angle-ply [±45°]2s and quasi-isotropic [0°/−45°/45°/90°]s laminates were tested at 20 J impact energy. The impact responses including contact force–time/central displacement and energy–time curves were recorded. The tendencies of the peak contact force, maximum displacement, bending stiffness, and energy dissipation with the increase in impact number were analyzed. Damage induced in the laminates was further evaluated. The results show that the impact resistance of the sandwich-like laminate is the weakest with the lowest peak load and the highest energy dissipation. The impact resistance of the quasi-isotropic laminate is better relative to the angle-ply laminate before the occurrence of fiber breakage, whereas the damage tolerance of the angle-ply laminate is higher with relatively slower damage accumulation at subsequent impacts.
Deglobalization: Reasons and Effects
Authors: Felbermayr Gabriel
Published: December 2023

Globalization, e.g. as measured by the ratio of global trade to global production (or GDP), has stopped advancing and may well recede in the years to come. Whether this is harmful for economic welfare depends on the precise reasons of this development. The effect of increasing border measures on GDP, however, is quite clearly negative. Because technological progress will continue to lower trade costs, globalization will bounce back forcefully when the geopolitical environment becomes more benign again.
Path to global knowledge: a review of Chinese scholars on international publishing
Authors: Guo Ke , Zhou Hui , Chen Peiqin
Published: December 2023

The article selects 634 papers authored by Chinese scholars on international publishing from CNKI, China’s foremost dataset for Chinese academic papers, in the past three decades. Employing the thematic analysis, the article explores the trends, developments and issues deliberated by Chinese scholars in the realm of international publishing. The article first scrutinizes the major themes discussed by Chinese scholars, revealing an evolution in their perceptions on international publishing. This evolution progresses from initial awareness in the first stage to adeptly handling challenges and enhancing the quality of international publishing in the second and third stages. In the fourth stage, scholars in China emphasize distinctive Chinese characteristics. The second part of the article outlines six issues deliberated by Chinese scholars in the field of international publishing, including international influence, contextual debates, English language, academic motivations, evaluation systems and publication charges. These six issues underscore the resilience and proactive efforts exhibited by Chinese scholars as they endeavor to adapt to and integrate into the international academic arena. In conclusion, the article summarizes the features of Chinese scholarship on international publishing and advocates that Chinese scholarship continues its engagement in global collaboration to make a more substantial contribution to global knowledge production.
“You are certainly my best friend” – Translating adverbs of evidential certainty in The Picture of Dorian Gray
Authors: Protopopescu Daria
Published: December 2023

The present article focuses on the analysis of how adverbs of evidential certainty are translated into Romanian in Oscar Wilde’s The Picture of Dorian Gray. Drawing on previous work, we argue that adverbs of certainty exhibit different interpretations function of their context of occurrence and their position in the clause. In this analysis, I am going to look at the different translation strategies employed in the ten Romanian translations of the book. We are interested in investigating the differences between the earliest translation and the most recent retranslations. We can safely assume that evidentiality is a universal semantic category that is coded differently in different languages. Therefore, it is going to be interesting to see how the rendering of evidential adverbs into Romanian differs from one translator to another across time. Adverbs of certainty express more often than not a degree of confidence on the part of the speaker alongside the speaker’s attitude toward the content of the sentence.
Thinking Gestures. On How the Philosophical Conceptualization of Ordinary Life Can Be Shaped by Art Practices
Authors: Formis Barbara
Published: December 2023

As a speculative and abstract discipline, philosophy is traditionally considered to be in dialectical tension with physical experience and daily practice. In contrast to this conventional and idealistic perspective, and in line with aesthetics as embodied knowledge, this article attempts to show that not only do we constantly think via gestures, movements, and physical experiences but also that there is no need to disconnect a concept from practice. Passing from Wittgenstein’s idea of “form of life” to the pragmatist aesthetics initiated by Dewey’s idea of “art as experience,” I propose an analysis of the philosophical framework of postmodern dance (Yvonne Rainer) and of Happenings (Allan Kaprow), in order to underline the theoretical and conceptual research that is already at work in the field of contemporary art practice, the latter being understood as a sensorial dimension intrinsically linked to ordinary life. My general argument is that gestures, which are an inescapable and vital part of everyday life, can be foregrounded by certain artistic practices without corrupting or theatricalizing their ordinariness.
Gender Differences in Business Record Keeping and Planning: Evidence from Informal Enterprises in Iraq
Authors: Gholipour Hassan F. , Goodell John W. , Cheratian Iman , Goltabar Saleh , Lahmar Oumaima
Published: December 2023

Business record keeping, along with business planning, are foundational steps in businesses moving from informal stature to contributing to the capitalization of assets. Thus, the transitioning of informal businesses to business record keeping and planning is significant for economic development. The purpose of this study is to investigate whether there is a relationship between the gender of informal business owners and their engagement in business record keeping and planning in an emerging economy. We take advantage of a unique data set on informal enterprises in Iraq to show that women, versus male, leaders of informal businesses are more likely to adopt business record keeping and formal business planning. Following the foundational theories of Max Weber (Gerth and Mills 2014), we attribute our results to groups that are excluded from dominant relationship networks relying more on rational bureaucracy. Results will be of great interest to scholars and policymakers interested in the impacts of gender differences on financial development.
The defender of orphans
Authors: István H. Németh
Published: December 2023

In the middle of the 17th century a transformation of states can be observed. The strives of early absolutist states were aimed at the increase of their economic and, in turn, their military potential. These goals were served by social policy measures aimed at increasing economic effi ciency and increasing state revenues. The development of central administration and regulations for orphan aff airs also served to maintain labour force and economic potential. The preservation of orphans’ property was intended to keep the economy going, and in the case of destitutes, orphanages intended to concentrate the workforce. The measures introduced in the German principalities soon appeared in the provinces of the Habsburg Monarchy. In the first quarter of the 17th century, the first theoretical work on orphan aff airs was written, and in the second half of the century it was followed by the first royal decree based on the principles set out in this volume. The aim of these provisions was to ensure the preservation and the control of the assets of the orphans by state means. Similar provisions to the Monarchy’s provinces were enacted in the Hungarian Kingdom in the last third of the 17th century. The offices introduced in the Austrian provinces, the separate Orphan’s Court (árvaszámvevőszék), the keeping of register on orphans (árvakönyv), and the continuous scrutiny of guardians were introduced in the free royal towns in the first third of the 18th century. All of this went parallel with the administrative reforms ordered in towns. The reform measures introduced regarding orphan affairs were realized at a varying pace one town to another, but by the end of the first third of the 18th century, the orphan regulations developed in the Austrian provinces had become established in all the free royal towns.
A katolikus papi hivatás és normatív elvárások a 18. század második és a 19. század első felében
Authors: Zoltán Gőzsy
Published: December 2023

In the 18th century, the academic quality of the education of priests steadily increased, and in the last decades of the century the practical application of the acquired knowledge became more and more important. The optimisation of theory and practice led to a strong professionalisation of the vocation of preists. Th e basic concept of this paper is that by the early 19th century, the Catholic clergy, through its internal development and the expectations of secular power, had a vocational identity, the formulation of which was shaped by everyday challenges and feedback.
Spatiotemporal Correlation between Amyloid and Tau Accumulations Underlies Cognitive Changes in Aging
Authors: Kim Chan-Mi , Diez Ibai , Bueichekú Elisenda , Ahn Sung , Montal Victor , Sepulcre Jorge
Published: December 2023

It is poorly known how Aβ and tau accumulations associate at the spatiotemporal level in the in vivo human brain to impact cognitive changes in older adults prior to AD symptoms onset. In this study, we used a graph theory-based spatiotemporal analysis to characterize the cortical patterns of Aβ and tau deposits and their relationship with cognitive changes in the Harvard Aging Brain Study (HABS) cohort. We found that the temporal accumulations of interlinked Aβ and tau pathology display distinctive spatiotemporal correlations associated with early cognitive decline. Notably, we observed that baseline Aβ deposits—Thal amyloid phase Ⅱ—related to future increase of tau deposits, Braak stages Ⅰ–Ⅳ, both displaying linkage to the decline in multi-domain cognitive scores. We also found unimodal tau-to-tau and cognitive impairment associations in broad areas of Braak stages Ⅰ–Ⅳ. The unimodal Aβ-to-Aβ progressions were not associated with cognitive changes. Our results revealed a multifaceted correlation of the spatiotemporal Aβ and tau associations with cognitive decline over time, in which tau-to-tau and tau–Aβ interactions, and not Aβ independently, might be critical contributors to clinical trajectories toward AD in older adults.

Censura manifiesta y actividad lingüística
Authors: García Murga Fernando
Published: December 2023

La censura controla por motivos ideológicos la comunicación. Este trabajo analiza la influencia de la censura en la formulación del mensaje. El estudio se centra en la censura manifiesta sobre el mensaje. El emisor, entonces, activa el parámetro censor (y el de receptor) en la representación de la situación comunicativa. Así, el emisor construye simultáneamente dos teorías de la mente, y en cada una de ellas incluye información sobre los sistemas ideológicos en juego, así como información que permita evaluar el grado de amenaza del mensaje (poder relativo entre censor y censurado, distancia social entre ambos, grado de imposición, grado de difusión y ocasión). La actividad lingüística, por tanto, no puede ser espontánea, ya que se desarrollan estrategias como el desdoble del emisor, el distanciamiento respecto al contenido de lo dicho o la formulación del mensaje mediante metáforas no fosilizadas, eufemismos o formas casi homófonas que apunten a situaciones no comprometedoras.
Variación dialectal, diafásica y concepcional: el «mejor dicho» colombiano
Authors: Sainz Eugenia
Published: December 2023

El artículo pretende contribuir a la investigación sobre marcadores discursivos y variación, focalizando la atención en la expansión funcional experimentada por el reformulador mejor dicho en la variedad colombiana del español. En su empleo normal en la interacción espontánea actual, la unidad ha desarrollado valores conclusivos, formulativos y modales que se alejan del propiamente rectificativo y del uso europeo. A la luz de los datos disponibles en los corpus y bases de datos, partimos de la hipótesis de un proceso de coloquialización y de subjetivización surgido en la interacción dialógica e impulsado por dos factores: la elevada frecuencia de la partícula en la conversación espontánea y su empleo igualmente frecuente en dinámicas discursivas de intensificación pragmática en combinación con los recursos intensificadores (Briz 1998; Albeda 2007) característicos de la oralidad coloquial como la serie enumerativa, la repetición, la metáfora hiperbólica, el realce prosódico, la exclamación, o las construcciones consecutivas.

Caracterización morfológica y proceso de fijación de algunos marcadores de reformulación en coreano
Authors: Kim Heejung
Published: December 2023

A diferencia de la reformulación y sus marcadores en español, que se han tenido en cuenta desde diferentes perspectivas lingüísticas, en los idiomas no indoeuropeos como el coreano, más concretamente en la lingüística coreana, se cuenta con escasos trabajos sobre la reformulación (Kim 2021) u operaciones semejantes a ella como la aposición o paráfrasis (Li 2013; Choi 2016). No obstante, esto no significa que no exista la reformulación en coreano, sino que se lleva a cabo de manera distinta y compleja por las características aglutinantes de dicha lengua. Por ello, en el presente trabajo, tras observar algunas consideraciones previas sobre la reformulación, se estudian las características gramaticales de cuatro marcadores de reformulación en coreano (jeuk, got, geureonikka y malhajamyeon), así como su proceso de fijación morfológica.
Los efectos de la pornografía en la salud de las mujeres: una revisión de la literatura científica
Authors: Cantabrana Marta , Poncela-Casasnovas Julia
Published: December 2023

Que la pornografía o violencia sexual filmada genera un impacto en la vida y salud mental de quien la visiona, es una realidad evidente cada vez más estudiada. Para mostrar las consecuencias directas e indirectas de la pornografía en las mujeres y niñas que visualizan, son filmadas o conviven con hombres que visionan y reproducen la violencia sexual, debemos identificar los sesgos de género de la investigación científica actual. Este artículo es el resultado de la revisión de literatura científica de todos los artículos de investigación, publicados desde 2021, con las palabras clave pornography & health. Los resultados responden a las siguientes preguntas de investigación: el sexo de la muestra; si hablan de salud; si especifican algún impacto en la salud física o mental segregados por sexo; si se establece una relación entre pornografía y violencia sexual; si se habla de la pornografía o de su consumo como algo inocuo, bueno o nocivo para la salud. Nuestro análisis evidencia que, en la investigación científica sobre pornografía y salud, no se diferencia por sexos en la mayoría de los artículos; no se asocia la violencia sexual a quienes la ejercen (los hombres); estudia principalmente las repercusiones de la pornografía en la salud de los hombres; se patologiza el hecho de que los hombres reproduzcan lo que ven en la pornografía y el consumo elevado que tienen. Los estudios sobre la repercusión en las mujeres que visionan pornografía son escasos y centrados en malestares psicológicos o físicos sin determinar; no existen estudios que muestren las implicaciones en la salud de las mujeres cuando sus parejas varones visionan pornografía; y, finalmente, no existe ningún estudio que investigue las consecuencias en la salud física y mental de las mujeres filmadas en la pornografía.

El estudio tuvo como finalidad evaluar las propiedades psicométricas de la Escala de Miedo a la Muerte de Collett-Lester (CL-FODS). Participaron 448 universitarios [H: 174, M: 274, DE: 3.0, ME: 23.27]. En el análisis factorial confirmatorio, se evidenció mejores valores en el modelo bifactor (χ²/gl = 2.54, CFI = .91, TLI = .90, SRMR = .051, RMSEA = .06, AIC = 33467.22, PUC =.78, ECV = .77, Omega H = .91). Asimismo, se halló que la escala presenta un efecto medio en la validez convergente con el miedo a la covid-19 (r=.49).  Además, se obtuvo una confiabilidad en la escala general (ω=.96) y por dimensiones (MPM ω=.87; MPPM ω=.91; MMO ω=.90; MPMO ω=.92). Posteriormente, se corroboró, a través de la invarianza de medición, que el constructo no guarda diferencias según sexo y edad. Finalmente, se llegó a la conclusión de que la CL-FODS tiene buenas propiedades psicométricas.

Distanciados, pero conectados: importancia del vínculo pedagógico en la enseñanza remota por emergencia
Authors: Fernández Godenzi Adriana Isabel
Published: December 2023

La presente investigación buscó analizar los cambios producidos en el vínculo pedagógico dentro de la educación remota por emergencia (ERT) implementada a raíz de la pandemia por la COVID-19. Específicamente, se planteó describir tanto las formas de interacción dentro del proceso de enseñanza-aprendizaje que han tenido los/las estudiantes con sus docentes, como con sus compañeros/as. Para ello, se realizaron entrevistas grupales virtuales a doce estudiantes universitarios peruanos. La selección de los/las participantes fue intencionada y por conveniencia. Como resultados, se logró verificar que el paso obligado a la virtualidad ha generado ausencias, distancias y desconfianzas que han afectado sus procesos de enseñanza-aprendizaje, así como también ha permitido que emerjan la empatía y la posibilidad de innovación metodológica en el aula virtual. Finalmente, se concluye que para los/las estudiantes el vínculo pedagógico intersubjetivo con sus docentes y entre ellos/as es crucial en la generación y el sostenimiento de procesos de aprendizajes significativos.
Práctica de la guardia psicológica desde la terapia Gestalt
Authors: Raymundo Villalva Ornella , Ramos Valdivia Luis Carlos , Bendezú Santisteban Judith , Lins Cardoso Claudia
Published: December 2023

La intervención psicológica tomó un rol importante durante la pandemia, debido al surgimiento de problemas emocionales como ansiedad, angustia y depresión. En el presente estudio, se analizó la práctica de la guardia psicológica (GP) virtual, desde la terapia Gestalt. Los psicólogos(as) de guardia atendieron durante los primeros meses del confinamiento (marzo - julio del 2020). Se usó el método fenomenológico para describir las experiencias de 10 de ellos, quienes ofrecieron asistencia, gratuita y virtual, a personas provenientes de diversos países de América Latina. Como resultado, se identifica la práctica de la GP como un aprendizaje bilateral, uso de la epoché, resonancias, recursos técnicos y encuentro yo-tú. Asimismo, se rescata la presencia de la actitud altruista y se valida la práctica de la GP como forma de intervención en la promoción, cuidado y prevención de la salud mental.

Authors: Markauskaitė Lina
Published: December 2023

The paper analyses conceptual relations between the aims of the introduction of Virtual Learning Environments (VLE) and the informatics curriculum in the lower secondary school of Lithuania. The article investigates this issue from two opposite perspectives. First, it looks, how the VLE could help to attain the objectives of informatics curriculum. Second, it discusses, what skills and knowledge of students should be developed during the lessons of informatics in order to use VLE efficiently for different other teaching and learning objectives.

The pupil's individual work skills' development teaching mathematics at Lithuanian schools (5–9 decades of the 20th century)
Authors: Ažubalis Algirdas
Published: December 2023

The article gives a profile on developing a system of individual tasks in mathematics by com­mon efforts of specialists in didactics and highly experienced teachers. Initially individual tasks are classified on the basis of task performance end. As a result they fall into two basic groups: a) tasks for developing practical skills of the knowledge gained; and b) tasks for developing new knowledge skills. Further assignments are classified by the degree of creativity they require and fall into the following four groups: 1) reproductive exercises; 2) reconstruction exercises; 3) variation exercises; and 4) creative exercises.

Stability analysis of parameters of the GDP components models
Authors: Kaminskienė Bronislava , Avdejenkova Vitalija
Published: December 2023

Flash estimation of GDP by production approach has been stated in Statistics Lithuania. Econometric methods are used for estimation of GDP components. The main problem is that time series are quite short and GDP is affected by results of work of single enterprises. That’s why it’s very important to know if the parameters of the models are stable or not.Main purpose of this paper is to evaluate stability of the GDP components models. This is done by generation of random series (with Gaussian and Student distributions) as a new residuals and recalculation of parameters with new dependent variables, which are equal to the already estimated model plus generated residuals.Main results of this work are quite satisfactory – new estimators are very close to first ones (most cases the error is less than 1 per cent). Exceptions are only the time series where residuals had outliers. Suggestion is to evaluate outliers prior to parameters estimation.

Object under analysis is general biological type. The parameters, that is limited by biological code and making dependant on multiplication and growth processes of biological type, are formalized with scalar matrixes. External influences are formalized with scalar functions' matrixes of vector arguments. Multipli­cation and growth process mathematical models of general biological type have been made. These models are oriented into their calculation within simulation modeling system SIMULINK.
Імперська візія Іосіфа Бродського у репрезентації венеції (на матеріалі есею “Watermark”)
Authors: Кравченко Аріна
Published: December 2023

Нині як ніколи необхідний неупереджений, уважний та критичний підхід до російської літератури, зокрема, до тієї її категорії, яку критики прочитують як аполітичну, оскільки наявні дослідження, на жаль, часто не відображують реального стану речей, приховують факти, які не вписуються до традиційної імперської культурної міфології, та загалом виконані в межах усталеної ідеології.

          У цій роботі розглядається конструювання імперської ідентичності Іосіфа Бродського – російського поета, есеїста, публічного інтелектуала та Нобелівського лауреата від 1986-го року. На прикладі есею “Watermark” аналізується один із проявів імперськості у творчості Бродського, а саме колоніальне ставлення до жінки, топос завоювання міста як завоювання жінки, ставлення до реперезентованих у тексті колоніальних суб’єктів. Фокусом дослідження є авторський міф Бродського та те, як він корелює з мотивом завоювання Венеції в есеї “Watermark”.
Decolonial Processes in Modern Ukrainian Literature through the Disclosure of the Soviet Man Image. City Space as One of the Identity-Forming Factors
Authors: Pidburtna Diana
Published: December 2023

A post-colonial approach to literary studies of modern literature, in particular Ukrainian, has gained considerable popularity over the last decade. Clearly, the collapse of the Soviet Union and the subsequent attainment of independence have laid the foundation for the development of post-colonial studies in our territory. Injuries inflicted during the long period of colonisation (although not all researchers agree to use this term, noting the absence of a key characteristic of the colony — “a large body of water” is missing) have been understood and reflected both in literature and its researchers. However, currently we are at a stage, when writers are moving beyond the refl ection typical for post-colonial viewpoints, delving into the exploration of logical connections between events and their consequences, examining ways to process these traumas. Therefore, in modern research, the decolonial approach, which emerges as a branch of postcolonial thought, is more relevant. In particular, this is discussed by Agnieszka Matusiak and Tamara Hundorova.Tamara Hundorova identifies a unique form of decolonial aesthetics in Ukrainian literature — aesthesis. This is the manifestation of the unknown, even the opposite of the generally accepted modern concept of “aesthetics” — corporeality, sensuality, and mystical practices. Agnieszka Matusiak observes that modern Ukrainian science and culture have undergone a ‘decolonial turn’ (decolonial-detotalitarian, as she calls this phenomenon, a complete shift in emphasis in discussions about Donbas). Decolonisation is intrinsically linked in Ukrainian realities with de-Sovietization. While at the governmental level, this occurs through changing street names and re-evaluating Soviet political figures, people raised under this system find it challenging to shed an identity formed under vastly different values and conditions. The article aims to showcase the depiction and transformation of the Soviet man in modern Ukrainian literature, illustrating changes that signify a shift towards a decolonial perspective. Also of interest are the aspects of traumatic memory and the identity crisis of characters, invariably linked with the disintegration of the Soviet Union.
