Revisiting Kenny G (Colloquy)
Authors: Carson Charles D.
Published: May 2023

From fusion jazz, to quiet storm, to neo-soul and lo-fi hip hop, jazz has often been used as a marker of authenticity in contemporary Black popular genres. Given his disproportionate popularity, the class-ing, racialization, and gendering of Kenny G in popular culture has become, in effect, the lens through which we evaluate all forms of crossover jazz. Ultimately, critiques that focus on Kenny G as a means to dismiss such musics are rooted in racialized discourses of authenticity that ignore the long tradition of crossover projects that characterize Black popular musics broadly.

Published: May 2023

Geological mapping undoubtedly plays an important role in several studies and remote sensing data are of great significance in geological mapping, particularly in poorly mapped areas situated in inaccessible regions. In the present study, Principal Component Analysis (PCA), Band Rationing (BR) and Minimum Noise Fraction (MNF) algorithms are applied to map lithological units and extract lineaments in the Amezri-Amassine area, by using multispectral ASTER image and global digital elevation model (GDEM) data for the first time. Following preprocessing of ASTER images, advanced image algorithms such as PCA, BR and MNF analyses are applied to the 9ASTER bands. Validation of the resultant maps has relied on matching lithological boundaries and faults in the study area and on the basis of pre-existing geological maps. In addition to the PCA image, a new band-ratio image, 4/6–5/8–4/5, as adopted in the present work, provides high accuracy in discriminating lithological units. The MNF transformation reveals improvement over previous enhancement techniques, in detailing most rock units in the area. Hence, results derived from the enhancement techniques show a good correlation with the existing litho-structural map of the study area. In addition, the present results have allowed to update this map by identifying new lithological units and structural lineaments. Consequently, the methodology followed here has provided satisfactory results and has demonstrated the high potential of multispectral ASTER data for improving lithological discrimination and lineament extraction.
Morphometric analysis of pebbles in verification of transport processes and interpretation of palaeoenvironment: A case study from the Ogwashi Formation (Oligocene), Niger Delta Basin, Nigeria

Published: May 2023

The present paper discusses a palaeoenvironmental interpretation of the Oligocene Ogwashi Formation (Niger Delta Basin, Nigeria) through morphometric analysis of pebbles, a research method essentially depending on the quantitative evaluation of pebble size and shape which change during transport processes in a range of depositional environments. The relationship of bivariate and ternary-diagram plots of independent functions was determined from freshly exposed sandstone sections in quarries at Ibusa, near Asaba, Nigeria. The grain size of pebbles ranges from fine (11.00 mm) to very coarse (41.33 mm), with a mean size of 21.05 mm (coarse pebbles). A bivariate plot of the flatness index vs maximum projection sphericity index shows 37% of the pebbles to fall within a beach (marine) environment, and 33% within a fluvial environment; the remaining 30% are uncertain. The maximum projection sphericity index vs oblate-prolate index bivariate plot indicates that 47% of pebbles fall within a marine environment and 22% within a fluvial environment, while the remaining 31% are uncertain. The sphericity-form ternary diagram plot shows that the pebbles primarily comprise bladed, platy, very bladed and very platy of near-equal proportions with minor elongate and very elongate stones, which suggests that the pebbles are diverse in origin. The sphericity-form bivariate plot indicates that the pebbles are largely of disc and blade shapes with a minor number of spherical and rod shapes. The near-equal proportion of pebbles in different segments of the bivariate and ternary diagram plots, and the wide distribution of the pebble grain sizes and shapes suggest the Ogwashi Formation is composed of redeposited sediments that likely were transported and deposited in a mix of marine and fluvial settings with possible transitional environments. In other words, the pebbles can be interpreted as marine-influenced fluvial sediments in marginal-marine settings.
Palaeoenvironmental and palaeoclimatic inferences based on X-ray computer tomography: a case study of alkaline lake deposits in Hungary
Authors: Alzoubi Nour N. , Gulyas Sandor , Geiger Janos
Published: May 2023

Widely distributed freshwater carbonate sediments, i.e., limestone, dolomitic limestone and dolomite, developed in inter-dune alkaline ponds of the Danube-Tisza Interfluve in the centre of the Carpathian Basin during the Holocene. The key parameters that determine the formation of any given type of carbonate mineral (calcite, dolomite) are temperature, evaporation rate, pH and ion concentrations, in addition to CO2 absorption by aquatic plants. CT analysis is capable of recording small-scale density variations attributable to compositional differences of sedimentary rocks. As the type and proportion of rock-forming minerals and other components is an artifact of past environmental and climatic conditions, CT values may act as potential palaeoenvironmental proxies. The present study compares variations in rock-forming components obtained for freshwater carbonates utilizing the CT method with already available geochemical and palaeoecological proxy data. Variations in molluscan ecology and isotope geochemistry, sedimentation times and CTbased rock density values all indicate the relevance of millennial-scale, climate-driven changes in carbonate formation. As previously observed, the emergence of colder conditions in the North Atlantic, which resulted in increased cyclonic activity and heavier rainfall in western Europe and the Danube watershed area between 10.3 and 9.3 kyr cal BP, resulted in the emergence of humid conditions favouring a rise in the groundwater table at our site and precipitation of calcite from pore waters as opposed to high-magnesium calcite. This is clearly reflected in a negative shift in CT density values in our dated rock samples.

Explicit solutions of the Dirichlet–Schrödinger problem via the new cylindrical Poisson–Schrödinger kernel method
Authors: Qiao Lei
Published: May 2023

In this paper, we study the cylindrical Schrödinger operator and construct a modified cylindrical Poisson–Schrödinger kernel, in analogy to
the classical theory of the Laplacian in a strip.
A new method expressing explicitly the modified cylindrical Poisson–Schrödinger kernels of any degree is obtained, and a formula expressing the modified cylindrical Poisson–Schrödinger integrals in terms of Nevanlinna–Schrödinger norms is deduced.
Applications in the solutions of Dirichlet–Schrödinger problem are described. More specifically, the existence and uniqueness of explicit solutions to the problem mentioned above for the cylindrical Schrödinger equation are obtained.
It is shown that our method yields more explicit results than do other methods. Much more challenging geometric configurations, such as a cylinder with a rough base bear new and interesting challenges arising from the lateral boundary conditions. These have-at least to our knowledge-not been addressed before.

Kompromiss und Demokratie. Eine begriffsgeschichtliche Annäherung
Authors: Rojek Sebastian
Published: May 2023

In unserer Gegenwart gilt Kompromissfähigkeit als zentrale demokratische Tugend und Politiker, Journalisten und die Wissenschaften sprechen gerne und viel über Demokratie und Kompromiss. Ausgehend von dieser Beobachtung widmet sich der Aufsatz einer historisch-semantischen Rekonstruktion des Kompromissbegriffs und fragt danach, wann und unter welchen Umständen sein Aufstieg in der politisch-sozialen Sprache Deutschlands begann. Die Untersuchung macht deutlich, dass der Kompromiss – verstanden als Schiedsgerichtsverfahren – eine lange Tradition alteuropäischer Begrifflichkeit aufweist und in Deutschland erst im Kontext der Sattelzeit eine neue Bedeutung annahm, die sich bis in die Gegenwart fortsetzt. Die Studie verfolgt die Konjunkturen und argumentativen Muster, die mit diesem Begriff von der 1848er Revolution bis zum Ende des Ersten Weltkriegs verknüpft wurden. Dabei zeigt sich, dass der Begriff vom monarchischen Konstitutionalismus auf die Demokratie übertragen worden ist.
Exploring aural vocabulary knowledge for TOEIC as a language exit requirement in higher education in Taiwan
Authors: Li Chen-Hong
Published: May 2023

The Test of English for International Communication (TOEIC) is a high-stakes test for students in higher education in Taiwan to fulfill the English-language graduation requirement. However, little is known regarding the vocabulary threshold for the test or the effects of the lexical coverage and profiles of test items on the adequate comprehension of the test. This study used a validated Listening Vocabulary Levels Test (LVLT) and the TOEIC listening subtest to estimate learners’ aural vocabulary knowledge required for an exit TOEIC listening score. The findings showed: (1) aural lexical knowledge accounted for more than half of the variance in comprehension performance; (2) a minimum level of 3,000 word families for a lexical coverage of 98 % considerably affected the comprehension of spoken texts; and (3) lexical profiles varied in the individual parts of the listening subtest, with a range of 3,000–5,000 word families required for achieving a lexical coverage of 98 %. The crucial role of lexical knowledge/coverage in comprehension performance on the exit test was discussed.
On the recovery of internal source for an elliptic system by neural network approximation
Authors: Zhang Hui , Liu Jijun
Published: May 2023

Consider a source detection problem for a diffusion system at its stationary status, which is stated as the inverse source problem for an elliptic equation from the measurement of the solution specified only in part of the domain. For this linear ill-posed problem, we propose to reconstruct the interior source applying neural network algorithm, which projects the problem into a finite-dimensional space by approximating both the unknown source and the corresponding solution in terms of two neural networks. By minimizing a novel loss function consisting of PDE-fit and data-fit terms but without the boundary condition fit, the modified deep Galerkin method (MDGM) is applied to solve this problem numerically. Based on the stability result for the analytic extension of the solution, we strictly estimate the generalization error caused by the MDGM algorithm employing the property of conditional stability and the regularity of the solution.
Numerical experiments show that we can obtain satisfactory reconstructions even in higher-dimensional cases, and validate the effectiveness of the proposed algorithm for different model configurations. Moreover, our algorithm is stable with respect to noisy inversion input data for the noise in various structures.
Effect of case-based learning, team-based learning and regular teaching methods on secondary school students’ self-concept in chemistry in Maara sub-county, Tharaka Nithi county, Kenya
Authors: Arimba Antony Mugiira , Wamukuru David Kuria , Anditi Zachary Orato
Published: May 2023

The use of case-based learning and team-based learning may help increase students’ self-concept in chemistry. The purpose of this study was to fill this gap by finding out the effects of case-based learning, team-based learning and regular teaching methods on secondary school students’ self-concept in chemistry in Maara Sub-County, Kenya. The study employed a 3 × 2 × 2 pre-test, post-test quasi-experimental factorial design. The study targeted 18,611 students in 52 secondary schools. Purposive sampling was used to choose three co-educational secondary schools with similar characteristics in Maara Sub-County. A total of 106 form two chemistry students were selected for the study using simple random sampling method. The experimental groups were taught using case-based learning and team-based learning while the control group was taught by regular teaching methods. The three groups were compared two-by-two to find out groups in which the differences in self-concept in chemistry would occur. Student’s self-concept questionnaire was administered to the students in the three groups. The validity of the instrument was ascertained by experts from Egerton University. Pilot testing was done in Meru South Sub-County in schools with similar characteristics. Reliability of the instruments estimated using Cronbach’s alpha coefficient was 0.81. Descriptive and inferential statistics were used for data analysis at α = 0.05. The mean differences in self-concept in the post-test were statistically significant among the three groups. The results of this study may offer valuable knowledge to policy makers as well as chemistry teachers so as to give greater attention to chemistry self-concept among students. The study findings fill a knowledge gap of effectiveness of methods of teaching chemistry.

Cell protein biosynthesis is regulated by different factors, but implication of intercellular contacts on alpha and beta cell protein biosyntheses activity has not been yet investigated. Islet cell biosynthetic activity is essential in regulating not only the hormonal reserve within cells but also in renewing all the proteins involved in the control of secretion. Here we aimed to assess whether intercellular interactions affected similarly secretion and protein biosynthesis of rat alpha and beta cells. Insulin and glucagon secretion were analyzed by ELISA or reverse hemolytic plaque assay, and protein biosynthesis evaluated at single cell level using bioorthogonal noncanonical amino acid tagging. Regarding beta cells, we showed a positive correlation between insulin secretion and protein biosynthesis. We also observed that homologous contacts increased both activities at low or moderate glucose concentrations. By contrast, at high glucose concentration, homologous contacts increased insulin secretion and not protein biosynthesis. In addition, heterogeneous contacts between beta and alpha cells had no impact on insulin secretion and protein biosynthesis. Regarding alpha cells, we showed that when they were in contact with beta cells, they increased their glucagon secretion in response to a drop of glucose concentration, but, on the other hand, they decreased their protein biosynthesis under any glucose concentrations. Altogether, these results emphasize the role of intercellular contacts on the function of islet cells, showing that intercellular contacts increased protein biosynthesis in beta cells, except at high glucose, and decreased protein biosynthesis in alpha cells even when glucagon secretion is stimulated.

La evolución y el desarrollo de la metodología de la Educación Física ha estado orientada por distintos condicionantes y factores. La aportación de conocimientos y de fundamento conceptual de distintas ciencias (Anatomía, Pedagogía, Fisiología, Psicología etc.) determinaron las distintas orientaciones que en cada época la caracterizó. El primer referente que fue utilizado durante el s. XIX fue el uso de los materiales y aparatos gimnásticos. Los objetivos que sugirió esta orientación estuvieron casi absolutamente identificados con las destrezas motrices derivadas del uso de estos materiales. Para concretar el papel de estos aparatos y reconstruir la metodología imperante en esta época, en este trabajo, se elabora un inventario de materiales y aparatos usados en gimnasios y centros de enseñanza durante el s.

The contribution of knowledge and conceptual basis of several sciences (Anatomy, Education, Physiology, Psychology etc.) determined different approaches along history. The first reference used during the XIXth century was the use of materials and gymnastic implements. The objectives of this approach were almost entirely identified with motor skills derived from the use of these materials. To realize the role of these devices and rebuild the prevailing methodology at this time, an inventory of materials and equipment used in gyms and schools during the XIXth century is proposed in this paper.Key Words: Methodology.

Published: May 2023

The article deals with the Easter short stories by I. N. Potapenko, which play an important role in the writer’s work. His stories, written in the best traditions of Easter literature, develop the motifs of spiritual resurrection and renewal, forgiveness, sobornost’, universal brotherhood, participation in the Easter joy of the risen Christ, love for people (“Poetry,” “To embrace the whole world,” “Tar Barrels,” “Aunt Sasha,” “Truly Risen,” “Old Wives’ Tales”). The motif of empathy with the passion of the Lord resounds in “Three Easter holidays.” The phenomenon of false shame associated with an open confession of faith in Christ is explored in “False Shame.” The theme of “the inscrutability of the ways of the Lord” is revealed in “Cheap Purchase.” Memories of childhood or youth form the basis of the majority of the author’s Easter short story plots. Childhood memories associated with the celebration of Easter contribute to the spiritual healing and transformation of the heroes. Some of the Easter short stories are humorous in nature (“Aunt Olya,” “The Castle of Chukcha,” “Arbitration Court”). There is a parody of the Easter genre in “What you can see in a dream.” Most Easter short stories by I. N. Potapenko reflect the Orthodox concept of man with its ideas of salvation of the soul, repentance, redemptive suffering and spiritual transformation. The edifying and heartfelt Easter short stories by I. N. Potapenko remind us of the gospel values, make us reflect on the meaning of life, and urge us not to neglect the salvation of the soul for the sake of earthly well-being.
“ORNATUS DIFFICILIS” STYLE IN “THE TALE OF IGOR’S CAMPAIGN”
Authors: Sokolova Lidia
Published: May 2023

The opinions of scientists about the extent to which the text of “The Tale of Igor’s Campaign” was comprehensible to its contemporaries are divided. Some believed that “The Tale of Igor’s Campaign” was a folk work in the deepest sense of the word; its artistic essence was widely accessible to everyone. Others insisted that the refined and figurative style of the work required cultured readers, which made it a work for a select few. D. I. Chizhevsky, R. O. Yakobson and other scientists compared the style of “The Tale of Igor’s Campaign” with the “ornatus difficilis” style of Western European poetry of the 12th–13th centuries. According to R. O. Jacobson, it was characterized by riddle techniques, a concise hint instead of a detailed narrative, a deliberate heterogeneity of linguistic means, the use of neologisms, a complex game of tropes and figures, a deliberate combination of unrelated genres and sources, and a combination of pagan and Christian elements. According to the V. V. Kolesov’s reasonable remark, this overly broad characteristic of the style of “The Tale of Igor’s Campaign” still requires argumentation. In order to confirm the hypothesis that “The Tale of Igor’s Campaign” is a work in the “ornatus difficilis” style, this article examines some still partially unresolved readings of the monument, the understanding of which is complicated by stylistic techniques associated with the use of vocabulary and phraseology: individually authored or rare words, dialectisms, polysemous words and phrases that generate ambiguity (amphibolism) in the text, as well as phraseological occasionalisms.
THE PRINCIPLE OF DOMINANCE IN THE CHARACTERS OF THE NOVEL “DEMONS” BY F. M. DOSTOEVSKY (IN LIGHT OF THE ETHICAL TEACHINGS OF A. A. UKHTOMSKY)
Authors: Fedorova Elena
Published: May 2023

The article reveals the author’s model of the world in F. M. Dostoevsky’s novel “Demons” based on the analysis of the genre content of the work. Appeal to the allusive plan of the novel (allusions to the motifs, images, landscapes in Goethe’s drama “Faust” and I. S. Turgenev’s story “Faust”) allows the reader to engage in a kind of dialogue between Dostoevsky and his predecessors. However, the traditions of ancient Russian literature (traditions of the vision genre, orientation to the church calendar, reliance on the biblical word and Holy Tradition) allow us to draw a conclusion about the national originality of the work. In the hierarchical structure of the novel, the highest place is occupied by the Gospel Word and the patristic heritage, Sacred Tradition. The concept of personality in the novel allows us to reveal the ethical teaching of A. A. Ukhtomsky about the dominant and the chronotope. The article for the first time considers the Ukhtomsky’s concept of the dominant using the material of Stavrogin’s “confession” and the fate of Stepan Trofimovich, and concludes that a new dominant of heroes has been formed. The significance of the novel “Demons” lies not only in the warning about the destructive processes that can occur in society and in man, but also in the depiction of ways out of the crisis and restoring the personality, in particular, Shatov, Stepan Trofimovich and other heroes are helped by conciliar consciousness, faith in the Providence of God, love, and readiness for repentance. The study was carried out on the material of the reconstructed journal edition of the novel, carried out in the Complete Works (canonical texts).
MANIPULATIVE STRATEGIES USED BY PYOTR VERKHOVENSKY IN F. M. DOSTOEVSKY’S NOVEL “DEMONS”
Authors: Stepchenkova Valentina
Published: May 2023

The novel “Demons” presents a polyphony of the characters’ opinions, however, the revolutionary idea of Peter Verkhovensky, whose anti-Christian essence is revealed by Dostoevsky, is aggressively dominant. Revolutionary Machiavellianism finds its expression in the plot of the novel, which moves due to the active efforts of Pyotr Stepanovich, and the exposure of the hero’s demonic idea sets its anti-nihilistic genre vector. The narrative strategies of the novel are defined both through Verkhovensky’s ultimate goal — the “shock” and “decomposition” of the society’s spiritual and moral foundations to lead it to a revolution — and through the presentation of the hero’s communicative tactics on the way to this goal. Pyotr Verkhovensky uses the well-known “recipes” of the political “kitchen:” he agitates, propagandizes, intrigues, incites, tempts with future blessings, etc. The main mechanism of these acts is the psychological impact phenomenon. Precisely in view of this phenomenon it is explained how “the purest heart and the simplest people” can be turned into “demons.” Verkhovensky skillfully guesses the others’ mental structure and moral demands, studies the “living science of people,” as a result of which he develops a whole system of verbal and non-verbal methods of psychological influence, which allows him to influence people of different social status, characters and aspirations. The use of psychological influence methods can be observed in his dialogues and targeted monologues, non-verbal methods of psychological influence are expressed through gestures, looks, tone of voice, body position, gait, etc. Various methods of psychological influence of Pyotr Verkhovensky are correlated with a number of motifs with a negative connotation: flattery, hypocrisy, fear, threat, denunciation. There is a connection between the artistic embodiment of the principles of Pyotr Verkhovensky’s revolutionary tactics and the provisions of the revolutionary S. G. Nechaev, which were set forth in the Catechism of a Revolutionary (1869) that lent Dostoevsky his character’s ethical attitudes, the intention to commit a crime and the generally demonic spirit of the theses he presents. Consideration of the means of psychological influence through the analysis of the speech and behavior of Pyotr Verkhovensky not only allows to correlate his thoughts with the ideological basis of this historical document, but also helps in a holistic understanding of Dostoevsky’s novel.

Published: May 2023

A discussão de questões de fundo da estrutura da sociedade capitalista se revela obrigatória para a pesquisa empírica em andamento sobre as relações entre práticas de comunicação e a nova identidade da classe média neorrural das ecovilas. Se a busca por uma relação sustentável com a natureza é o fato mais visível na formação das ecovilas, as razões do protagonismo da classe média e o papel das mídia digitais na constituição de modos sustentáveis são pouco estudados. O objetivo deste artigo é apresentar alguns resultados a respeito do contexto e das mediações estruturais que motivaram a mudança de estilo de vida, retomando a noção de alienação do trabalho, do consumo e dos seres humanos em relação à natureza. Pretendemos, então, no decurso da próxima etapa da investigação, compreender o papel das práticas de comunicação interpessoais e das mediadas pelos dispositivos técnicos na reconfiguração das identidades de frações da classe média.

Tumefactive multiple sclerosis with the presence of tumefactive demyelinating lesions (TDL) is an infrequent manifestation of multiple sclerosis. It poses a diagnostic challenge, especially in attempts to differentiate it from a central nervous system neoplasm or other demyelinating disorders, such as neuromyelitis optica spectrum disorder (NMOSD). The article reports a case of a 40-year-old female during chronic steroid therapy administered due to an episode of idiopathic transverse myelitis. The patient developed tumour-like brain lesions in the left hemispheric parietal-occipital region. The diagnostic process was hindered by extended steroid treatment and a lack of patient compliance. This case is an example of insufficient knowledge about rare forms of multiple sclerosis and the need for a holistic approach involving a through analysis of medical history and previous medical records.

Extrapyramidal disorders are a rare presentation of multiple sclerosis. One such presentation is paroxysmal hemidystonia. Dystonia is, in the strict sense, the result of damage to various sites in the central nervous system. In one published cases series, lesions causing dystonia occurred in heterogeneous locations, most commonly in the basal ganglia, followed by the thalamus, brainstem, and white matter. In a series of 62 patients with thalamic or peritalamic lesions, only about 5% patients had paroxysmal dystonia. So far, there have been few reported cases of patients with paroxysmal hemidystonic symptoms associated with a specific damage to the central nervous system in the course of multiple sclerosis, especially as a relapse. For these reasons, we present a case of a 57-year-old female patient with a medical history of about 30 years of multiple sclerosis, who developed symptoms of paroxysmal left-sided hemidystonia as a relapse of multiple sclerosis.

Most CsCl-type intermetallics composed of group IV and VIII–XI transition metals have shape memory effect (SME), a phenomenon that occurs on a certain class of materials with an ability to undergo martensitic transformation (MT) during cooling. This advanced functional materials’ property is enabled by MT from high-temperature B2 phase of high symmetry to lower symmetry phases such as L10, B19 or B19’ upon cooling. Peculiarly, Ti50Ru50 with similar ordered B2 at high temperature remains ordered and stable with no phase transition down to room temperature. In this study, first-principles calculations based on density functional theory (DFT) are used to investigate the structural, thermodynamic and electronic properties of the stable Ti50Ru50 compound by systematically substituting part of the Ru atoms with ductile group 10 metal (Ni, Pd and Pt). This is an attempt to destabilizing B2 phase at 0 K through Ti50Ru50-xYx ternary alloying to promote MT that could yield SME.

Intestinal invagination is a mixed form of intestinal obstruction that occurs when one section of the intestine is telescopically immersed in the lumen of another and occurs mainly at the age of 3 months to 1 year, which is 90%, and mortality, according to the literature, ranges from 6 to 14.5%. Despite a sufficient number of scientific and clinical publications on the pages of medical journals regarding the diagnosis and treatment of intestinal intussusception, there are no fake simulators in the training of students and interns, which determines the relevance of this publication. Purpose - to improve the results of diagnosis and treatment of children with intestinal intussusception by analyzing domestic developments and visually studying the mechanism of its development with the help of a simulator both for the purpose of diagnosis and treatment - conservative disinvagination. Results. In today’s conditions, general practitioners and pediatricians are not trained to diagnose intussusception in children, that is, they do not have simple methods of examination. Hospitals usually do not have the equipment to examine and diagnose acute intussusception. In order to eliminate the gaps at the Department of Pediatric Surgery of the Bukovinian State Medical University, a dummy-simulator of intestinal intussusception «Garant» was developed and introduced into the educational process. Training on a simulator allows you to master the practical skills of diagnostics in the conditions of an X-ray room and conservative disinvagination followed by X-ray control. In turn, the development of skills by primary care physicians and pediatric surgeons in diagnosis and treatment will primarily improve the understanding of the onset of the disease and treatment methods. Conclusions. With certain and significant developments regarding the diagnosis and treatment of intestinal intussusception in children, the problem has not been solved, since some children seek help at the wrong time, and as a result of complications - necrosis, peritonitis with organ and multiple organ failure. The use of a scoring system for assessing the stage of invagination makes it possible to systematize the main prognostic indicators of sonographic and dopplerographic studies in order to determine an adequate method of treatment. Practicing the skills of diagnosis and treatment on the self-developed dummy «Garant» allows you to clearly understand the essence and purpose of the measures taken to establish and confirm the diagnosis of intestinal intussusception, evaluate the possibilities of various methods of conservative and surgical treatment and indications for them. No conflict of interests was declared by the authors.
Religious Experiences Are Interpreted through Priors from Cultural Frameworks Supported by Imaginative Capacity Rather Than Special Cognition
Authors: Van Mulukom Valerie , Lang Martin
Published: May 2023

In this commentary of McCauley and Graham’s book on mental abnormalities and religions, we identify a number of challenges, and present possible extensions of their proposed research. Specifically, we argue that no specialized religious cognition should be assumed, and instead suggest that the cases of mental abnormalities discussed in the book specify particular instances of religious content, and that other disorders may show a more causal relationship to religiosity. We argue that the discussed religious content may be best explained in the context of cultural frameworks and their contribution to experiencing the world through priors and predictive processing. Moreover, cognition required to understand and engage with religion, but not special to it, might crucially involve our capacity for imagination, supported by memory. Disorders in imagination are therefore expected to show likewise dysfunctions in religious phenomena.
