Health co-inquiry in migraine: Online participation and stakeholder experiences before and during the COVID-19 pandemic
Authors: Baucke Camden L. , Seifert Lauren S. , Kaelber Kara
Published: November 2021

A migraine is more than head pain, and chronic migraine can dramatically impact a person and those around her/him/them. To better understand those effects it is important to study the experiences of persons with migraine and their caregivers, family, friends, and health and mental health providers. When they collaborate, stakeholders may improve outcomes for persons with chronic migraine. One type of stakeholder cooperation is Health Co-Inquiry, involving a person-centered approach, activation of persons toward collaboration and improved health, evidence-based practice, and integrated care. The current study investigated Health Co-Inquiry at online forums, blogs, and bulletin boards where people came together to discuss migraine. A “Bifurcated Method” was used to conduct inductive, thematic analyses, quantitize themes, and cross-check themes using a robot program, which crawled the Internet to gather data about stakeholder sites and posts related to migraine. Key themes in the online narratives of migraine stakeholders included seeking and providing advice, help, and information. In addition, giving personal stories and testimonials, selling computer applications and products, and providing misinformation were frequent. Differences in the types of posts by various stakeholder groups were identified and may inform researchers about their varied perspectives and goals. Remarkably, migraine is still migraine–before a pandemic and during it. As such, migraineur concerns remained stable across thematic analyses of blog and forum posts before and during the worldwide COVID-19 pandemic.

Although sensorineural hearing loss (SHL) is relatively common, its cause has not been identified in most cases. Previous studies have suggested that viral infection is a major cause of SHL, especially sudden SHL, but the system that protects against pathogens in the inner ear, which is isolated by the blood-labyrinthine barrier, remains poorly understood. We recently showed that, as audiosensory receptor cells, cochlear hair cells (HCs) are protected by surrounding accessory supporting cells (SCs) and greater epithelial ridge (GER or Kölliker’s organ) cells (GERCs) against viral infections. Here, we found that virus-infected SCs and GERCs induce HC death via production of the tumour necrosis factor-related apoptosis-inducing ligand (TRAIL). Notably, the HCs expressed the TRAIL death receptors (DR) DR4 and DR5, and virus-induced HC death was suppressed by TRAIL-neutralizing antibodies. TRAIL-induced HC death was not caused by apoptosis, and was inhibited by necroptosis inhibitors. Moreover, corticosteroids, the only effective drug for SHL, inhibited the virus-induced transformation of SCs and GERCs into macrophage-like cells and HC death, while macrophage depletion also inhibited virus-induced HC death. These results reveal a novel mechanism underlying virus-induced HC death in the cochlear sensory epithelium and suggest a possible target for preventing virus-induced SHL.
Efficacy and safety of novel glycopeptides versus vancomycin for the treatment of gram-positive bacterial infections including methicillin resistant Staphylococcus aureus: A systematic review and meta-analysis
Authors: Jame Wissal , Basgut Bilgen , Abdi Abdikarim
Published: November 2021

Objective

To compare between current evidence of novel glycopeptides against vancomycin for the treatment of gram-positive bacterial infections.

Methodology

A systematic review and meta-analysis was done. Major databases were searched for eligible randomized control trials that assessed clinical success, microbiological success and safety profile of novel glycopeptides versus vancomycin for infections caused by gram-positive bacteria.

Results

This meta-analysis included eleven trials (7289 participants) comparing telavancin, dalbavancin and oritavancin with vancomycin. No differences were detected between novel glycopeptides and vancomycin for the treatment of skin and soft tissue infections (SSTIs) among modified intent-to-treat patients (OR: 1.04, CI: 0.92–1.17) as well as within the clinically evaluable patients (OR: 1.09, CI: 0.91–1.30). Data analysed from SSTIs, HAP and bacteremia studies on telavancin showed insignificant high clinical response in microbiologically evaluable patients infected with methicillin resistant Staphylococcus aureus (MRSA) (OR: 1.57, CI: 0.94–2.62, p: 0.08) and in the eradication of MRSA (OR: 1.39, CI: 0.99–1.96, P:0.06). Dalbavancin was non-inferior to vancomycin for the treatment of osteomyelitis in a phase II trial, while it was superior to vancomycin for the treatment of bacteremia in a phase II trial. Data analysed from all trials showed similar rates of all-cause mortality between compared antibiotics groups (OR: 0.67, CI: 0.11–4.03). Telavancin was significantly related with higher adverse events (OR: 1.24, CI: 1.07–1.44, P: <0.01) while dalbavancin and oritavancin were associated with significant fewer adverse events (OR: 0.73, CI: 0.57–0.94, p: 0.01; OR: 0.72, CI: 0.59–0.89, p: <0.01 respectively).

Conclusion

Efficacy and safety profiles of both dalbavancin and oritavancin were the same as vancomycin in the treatment of gram-positive bacterial infections in different clinical settings, while telavancin might be an effective alternative to vancomycin in MRSA infections, but caution is required during its clinical use due to the high risk of adverse events, especially nephrotoxicity.
The limited screening accuracy of the Patient Health Questionnaire-2 in detecting depression among perinatal women in Italy
Authors: Gigantesco Antonella , Palumbo Gabriella , Cena Loredana , Camoni Laura , Trainini Alice , Stefana Alberto , Mirabella Fiorino
Published: November 2021

Background

The PHQ-2 was recently recommended by the International Consortium for Health Outcomes Measurement as a form of initial perinatal screening, followed by the EPDS only for women with positive PHQ-2 score. However, the accuracy of the PHQ-2 in perinatal clinical practice has been barely researched, to date. In the present study, we aim to assess the accuracy of the PHQ-2 against the EPDS in a large sample of perinatal women.

Methods

A total of 1155 consecutive women attending eleven primary or secondary health care centres throughout Italy completed the EPDS and the PHQ-2 during pregnancy (27-40-weeks) or postpartum (1-13-weeks). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio, negative likelihood ratio, post-test probabilities and area under the curve (AUC) of the PHQ-2, using a cut-off of ≥ 3, were calculated.

Main findings

During pregnancy, PHQ-2 revealed low sensitivity (39.5%) and PPV (39.4%) but high specificity and NPV (97.5%). In postpartum, it revealed very low sensitivity (32.7%) and moderately high NPV (80.9%), but high specificity (99.3%) and PPV (94.4%). Given the low sensitivity despite the high specificity, the PHQ-2 demonstrated poor accuracy (AUC from 0.66 to 0.68).

Conclusion

Initial screening by means of PHQ-2 failed to identify an acceptable number of perinatal women at-risk of depression in Italian clinical practice. The PHQ-2 performance suggested that it has insufficient sensitivity and discriminatory power, and may be inadequate as a screening tool for maternal depression.
Provider views on rapid diagnostic tests and antibiotic prescribing for respiratory tract infections: A mixed methods study
Authors: Burrowes Shana A. B. , Barlam Tamar F. , Skinner Alexandra , Berger Rebecca , Ni Pengsheng , Drainoni Mari-Lynn
Published: November 2021

Background

Respiratory tract infections (RTIs) are often inappropriately treated with antibiotics. Rapid diagnostic tests (RDTs) have been developed with the aim of improving antibiotic prescribing but uptake remains low. The aim of this study was to examine provider knowledge, attitudes and behaviors regarding RDT use and their relationship to antibiotic prescribing decisions across multiple clinical departments in an urban safety-net hospital.

Methods

We conducted a mixed methods sequential explanatory study. Providers with prescribing authority (attending physicians, nurse practitioners and physician assistants) who had at least 20 RTI encounters from January 1, 2016 to December 31, 2018. Eighty-five providers completed surveys and 16 participated in interviews. We conducted electronic surveys via RedCap from April to July 2019, followed by semi-structured individual interviews from October to December 2019, to ascertain knowledge, attitudes and behaviors related to RDT use and antibiotic prescribing.

Results

Survey findings indicated that providers felt knowledgeable about antibiotic prescribing guidelines. They reported high familiarity with the rapid streptococcus and rapid influenza tests. Familiarity with comprehensive respiratory panel PCR (RPP-respiratory panel PCR) and procalcitonin differed by clinical department. Qualitative interviews identified four main themes: providers trust their clinical judgment more than rapid test results; patient-provider relationships play an important role in prescribing decisions; there is patient demand for antibiotics and providers employ different strategies to address the demand and providers do not believe RDTs are implemented with sufficient education or evidence for clinical practice.

Conclusion

Prescribers are knowledgeable about prescribing guidelines but often rely on clinical judgement to make final decisions. The utility of RDTs is specific to the type of RDT and the clinical department. Given the low familiarity and clinical utility of RPP and procalcitonin, providers may require additional education and these tests may need to be implemented differently based on clinical department.

Published: November 2021

Evaluation of the genetic diversity and an understanding of the genetic structure and relationships of chickpea genotypes are valuable to design efficient germplasm conservation strategies and crop breeding programs. Information is limited, in these regards, for Ethiopian chickpea germplasms. Therefore, the present study was carried out to estimate the genetic diversity, population structure, and relationships of 152 chickpea genotypes using simple sequence repeats (SSR) markers. Twenty three SSR markers exhibited polymorphism producing a total of 133 alleles, with a mean of 5.8 alleles per locus. Analyses utilizing various genetic-based statistics included pairwise population Nei’s genetic distance, heterozygosity, Shannon’s information index, polymorphic information content, and percent polymorphism. These analyses exemplified the existence of high genetic variation within and among chickpea genotypes. The 152 genotypes were divided into two major clusters based on Nei’s genetic distances. The exotic genotypes were grouped in one cluster exclusively showing that these genotypes are distinct to Ethiopian genotypes, while the patterns of clustering of Ethiopian chickpea genotypes based on their geographic region were not consistent because of the seed exchange across regions. Model-based population structure clustering identified two discrete populations. These finding provides useful insight for chickpea collections and ex-situ conservation and national breeding programs for widening the genetic base of chickpea.

Authors: Kadim Muzal , Tantri Aida Rosita , Ramadani Muhammad Indera
Published: November 2021

Background Irritable bowel syndrome (IBS) is a common gastrointestinal disorder in children and adults. The IBS is diagnosed by symptoms that fulfill the Rome IV criteria. This condition can impact quality of life, especially in adolescents.

Objectives To investigate the prevalence of IBS in high school students and analyze its risk factors.

Methods This cross-sectional study was done with e-questionnaires from Rome IV Diagnostic Questionnaire on Pediatric Functional Gastrointestinal Disorders (R4PDQ). Students from high school and occupational schools age 14 to 18-years-old in Jakarta were included in this study. Possible risk factors for IBS were analyzed using Fisher’s exact test for bivariate analysis and logistic regression for multivariate analysis.

Results Of 210 subjects, 10 (4.8%) had IBS. The IBS-M and IBS-C subtypes were more common than IBS-D. Gastrointestinal infection history was significantly associated with IBS (OR 7.1; 95%CI 1.7 to 29.3; P=0.013). Other factors such as gender, corporal punishment, asthma, spicy and fatty food consumption, as well as socioeconomic status were not significantly associated with IBS (P>0.05).  

Conclusion The prevalence of IBS in adolescents is 4.8%. History of gastrointestinal infection is a risk factor for IBS.

Published: November 2021

Background Hepatitis A is the most common cause of acute viral hepatitis, with a typical simple, self-limiting course. But it is not free from complications. Atypical presentations, such as in the form of prolonged cholestasis, ascites, pleural effusion, relapsing hepatitis, or fulminant hepatic failure, pose challenges to disease management. Knowledge about varying presentations and identification of factors associated with atypical presentations will help to early diagnosis of atypical courses of disease.

Objective To describe various atypical clinical presentations, biochemical findings of hepatitis A infection, and possible related factors.

Methods Ninety-five children aged 1 to 18 years, diagnosed with hepatitis A infection, and admitted to the Department of Pediatric Gastroenterology & Nutrition, BSMMU, Dhaka, Bangladesh from January 2015 to May 2018 were studied retrospectively.

Results Atypical presentations were manifested in 19 (20%) out of 95 children with hepatitis A virus (HAV) infection. The mean age of atypical patients [6.32 (SD 3.45) years] was significantly lower than that of typical patients [8.22 (SD 3.58) years] (P=0.0041). The most common atypical manifestation was ascites (11/19), followed by hepatic encephalopathy (9/19), acute liver failure (719), thrombocytopenia (2/19), pleural effusion (2/19), and cholestasis (1; 1.1%). Children with atypical features had significantly higher international normalized ratio (INR) and serum bilirubin, as well as lower hemoglobin level than the typical group. Children of atypical group had significantly higher number of organomegaly and coagulopathy.

Conclusion Ascites, hepatic encephalopathy, acute liver failure, thrombocytopenia, pleural effusion, and prolonged cholestasis were common forms of atypical presentation. Younger age, organomegaly, higher bilirubin level, prolonged PT, and decreased hemoglobin level could be predictive of an atypical presentation of HAV in children.
Neonatal hemochromatosis attributed to gestational alloimmune liver disease treated with intravenous immunoglobulin and exchange transfusion therapy: an evidence-based case report
Authors: Perma Iskandar Adhi Teguh , Jamarin Vini , Mulyana Kamajaya
Published: November 2021

Neonatal hemochromatosis (NH) is a rare fatal liver disease accompanied by hepatic and extrahepatic iron overload.1-3 Gestational alloimmune liver disease (GALD) is a materno-fetal alloimmune disorder and leading cause of NH.2,4,5 This condition allows an interplay between the maternal adaptive immune system and the fetus, resulting in an allograft to the mother. The mother becomes sensitized to an alloantigen expressed by the fetus and forms specific reactive antibodies. Immunoglobulin G (IgG) is transported through the placenta and attacks the fetal hepatocytes, resulting in severe loss of hepatocytes and fetal iron overload.3,6

Liver transplantation has been the only definitive treatment for NH for many years, with a survival rate of ±35%. Conventional therapy containing antioxidants and chelation agents reportedly have very poor success, with survival rate of only 10-20%. A new treatment paradigm involving intravenous immunoglobulin (IVIG) and exchange transfusion (ET) therapy has shown significant success in survival rate in NH, decreasing the need for liver transplantation.3,7,8

Here we present a case of NH caused by GALD and treated successfully with a combination of IVIG therapy and ET. We also aimed to evaluate the efficacy of IVIG and ET therapy for NH.

Authors: Alyabyeva M. V. , Alyabyeva T. M.
Published: November 2021

Any socio-economic systems, as they function, are subject to various changes and self-organization processes occur in them at a certain stage of development. In the methodology of the evolutionary-synergetic direction of the system analysis of economic systems, the problems of self-organization occupy a central place. The emergence of new needs or the creative creativity of society is of particular importance for launching the processes of selforganization. The article deals with the theoretical foundations of the processes of self-organization in socioeconomic systems, it is proved that such systems are under the influence of fundamental factors and energy interactions. The authors construct a scheme of the movement of the socio-economic system to self-organization, consider the options for the development of socio-economic systems at the enterprise level in states close to the bifurcation points, and identify the main attractors of their self-organization. The author also substantiates the emergence of a synergistic effect in the joint influence of attractors on the development of socio-economic systems and defines the main provisions of socio-economic synergetics.
SIBERIAN CLUSTERS: IMPACT ON THE REGIONAL ECONOMY
Authors: Bazhanov V. A.
Published: November 2021

An attempt is made to answer the question: have there been any positive shifts in the economy of the regions in the territory of which economic clusters have formed and are forming by 2020. Data from various sources on the number of clusters in the country and in the Siberian Federal District are presented. Shifts are estimated using generalized indicators calculated by the principal component method. As the initial data for the calculations, the indicators presented in the statistical collections “Regions of Russia. Socio-economic indicators” for the period from 2005 to 2018. The results obtained for the Siberian regions were compared for two years of the period under review: 2014 and 2018. Conclusions about the level of influence of cluster activities on the economy of the regions were carried out by changing the positions of the regions in their general list. As the analysis of the results of the component analysis showed for the Siberian regions under consideration, either maintaining positions or losing them in the direction of lowering the rating of the regions was characteristic. The exception was Krasnoyarsk Territory, which showed positive shifts in three of the four components. For some components, positive shifts could be seen in the Altai Territory and the Novosibirsk Region. An attempt to determine the full impact of the activity of clusters on the economy of the regions only according to available state statistics did not lead to the desired results.
QUESTIONS OF BUILDING A MODEL OF COOPERATIVE FEDERALISM IN THE CONTEXT OF LOCAL SELF-GOVERNMENT DEVELOPMENT
Authors: Belousova S. V.
Published: November 2021

The current problems of the lack of clear interaction between the levels of government, which have significantly manifested themselves during the implementation of national projects, have predetermined the need for a new stage of local self-government reform aimed at building a model of a single executive vertical based on cooperative federalism. In the article, the author analyzes two main trends in the development of this model: managerial centralization and cooperation. It is established that centralization has affected many aspects and directions of the implementation of power, but at the same time the problem of cooperation and coordination of actions of individual branches, spheres and levels of management remains. The author considers managerial cooperation from the point of view of the system approach on the basis of the types of system elements and ways of their interaction, which in general forms various directions and forms of cooperative interaction. The article establishes the structure of cooperation by types of system elements according to the law of system development and the corresponding forms of cooperative interactions. The analysis of the current implementation of financial, administrative, political, control and analytical cooperation allows us to identify existing problems and the required measures for the development of cooperative federalism in the aspect of implementing a complementary combination of centralization and cooperation.

Published: November 2021

The sustainable development of the region depends on many factors that affect the economic situation, investment attractiveness and prospects for the development of the social sphere. It is impossible to achieve positive changes in this direction without the widespread use of digital infrastructure, which is a powerful driver for the dynamic growth of the economy. Information and communication technologies can significantly speed up business processes involving interdepartmental interaction within the framework of state information systems. The creation of new information services allows the population to solve many problems remotely, without personal contact with the relevant organizations. The year 2020 has shown the need and the possibility of introducing elements of digitalization in various spheres of life in the shortest possible time, which did not seem to be a priority and important before. The effectiveness and quality of such solutions turned out to be so high that it allowed us to solve the tasks with the highest efficiency, in the shortest possible time and with a significant reduction in the use of human resources. The development of digital technologies creates a comfortable environment for large, medium and small businesses, as well as for solving urgent problems of the region’s population.

CHANGE MANAGEMENT: METHODOLOGY OF INSTITUTIONAL TRANSFORMATION OF SOCIAL AND LABOR RELATIONS
Authors: Pyatkova O. N.
Published: November 2021

Economic growth unambiguously presupposes the development of enterprises based on the introduction of new technologies that require changes in the forms of organization of labor, its content. This inevitably entails staff resistance to the implementation of changes. Known techniques solve this problem, but they cannot be called effective and efficient. The reason is that when influencing personnel, they are guided mainly by the labor behavior of employees. Resistance of personnel, expressed in the opportunistic behavior of employees in the performance of new job duties, new labor procedures, solving old tasks with new methods and means. But the reason for the resistance goes deeper. It lies in the content and structure of social and labor relations. In the article, this the problem is considered through the prism of the institutional structure of social and labor relations, which are the essential basis of labor. A method of transforming them before introducing changes in order to reduce the potential of workers’ resistance is also proposed.

Authors: Zimmer Geórgia Cristiane , Folmer Vanderlei , Regina Bonini Marzari Mara , Colman Espíndola Lima Quelen
Published: November 2021

Este trabalho teve como objetivo investigar percepções e concepções de professores e alunos na realização da experimentação de Química no Ensino Médio, em um colégio técnico integrado. Para alcançar o objetivo proposto, realizou-se uma entrevista com as duas professoras de Química, e um questionário foi aplicado com os alunos do terceiro ano do Ensino Médio. Na entrevista com as professoras, foi observado que a falta de um laboratorista e a baixa carga horária da disciplina de Química dificulta a realização das aulas experimentais. Referente às respostas dos alunos, constatou-se que eles gostam das aulas de Química teóricas e experimentais, sendo que por meio da experimentação conseguem correlacionar a teoria com a prática. Isso pode estar relacionado ao método de ensino que as professoras utilizam e também pelo colégio apresentar um laboratório de Química equipado, e que quando possível, são realizadas aulas experimentais de Química. Este trabalho mostra que mesmo em uma escola técnica equipada, ainda se tem outros fatores que dificulta a frequência das aulas práticas no laboratório de Química. Para aprofundar os estudos realizados é necessária uma maior investigação a respeito de como esses fatores elencados afetam diretamente o ensino, envolvendo um maior número de escolas.  Além disso, torna-se importante avaliar de que forma, mudanças no método de ensino influenciam diretamente no aprendizado de Química.

Este trabalho teve como objetivo analisar os discursos apresentados pelos acadêmicos de Ciências Biológicas de duas universidades brasileiras quanto a seus conhecimentos em relação ao tema evolução biológica, buscando identificar indícios de que conhecimentos provenientes da teoria da síntese estendida estão (ou não) sendo abordados durante a graduação. Para a constituição dos dados, foi solicitado que os sujeitos apresentassem justificativa para seu posicionamento de concordar ou discordar das afirmativas propostas sobre o tema. As explicações dos estudantes foram interpretadas por meio da análise de discurso, que permitiu a identificação da presença de termos como epigenética, plasticidade fenotípica, desenvolvimento biológico, entre outros. Concluiu-se que a citação desses conceitos configura-se em indício discursivo de que esses conhecimentos estão ampliando a forma como a evolução está sendo compreendida também pelos estudantes de graduação dos cursos de Ciências Biológicas investigados.
Emergencia y evolución de formas de pensamiento aditivo asociadas al vector conteo simple
Authors: Pantano-Mogollón Leonardo
Published: November 2021

En este artículo se presentan algunas consideraciones teóricas y empíricas en relación con la emergencia y evolución de formas de pensamiento aditivo asociadas al vector conteo simple en la actividad realizada por un estudiante al abordar una tarea asociada al conteo de cantidades. La emergencia y evolución de formas de pensamiento aditivo asociadas al vector conteo simple está caracterizada por los medios semióticos de objetivación que son movilizados por el estudiante en la actividad que emerge al abordar la tarea. El análisis del episodio de actividad, a través de la metodología multi-semiótica, sugiere, primero, que las formas de pensamiento aditivo se actualizan en la actividad desarrollada por él, a través de las acciones corpóreas, la actividad perceptual, las expresiones lingüísticas enunciadas y los signos numéricos utilizados. Segundo, que estas formas evolucionan en paralelo a la manera como se desarrolla y evoluciona la actividad, puesto que en la actividad se evidencian momentos distintos pero complementarios, los cuales están determinados por el refinamiento de los medios semióticos de objetivación que son movilizados. Este refinamiento da lugar a la actualización de formas cada vez más elaboradas de percepción, gestualidad, simbolización y discursividad.

Published: November 2021

O presente artigo busca compreender, a partir da proposição de uma sequência de ensino, o processo de aprendizagem do conceito função, com um grupo de estudantes de alguns cursos da educação superior. Tal abordagem faz-se necessária tendo em vista as dificuldades apresentadas pelos estudantes em relação a tal conceito. Aprofundou-se uma atividade que teve como objetivo explorar o nuclear do conceito função – correspondência, relação, dependência e variação – a partir de uma investigação que questiona: quais são as principais fragilidades e dificuldades apresentadas pelos estudantes em uma atividade envolvendo a essência do conceito função? Buscaram-se, na Teoria dos Registros de Representação Semiótica e na Teoria dos Campos Conceituais, aportes teóricos para sustentar este estudo. Os dados foram construídos e tratados a partir da Análise Textual Discursiva, tendo como categoria de análise: sentidos atribuídos pelos estudantes na significação do conceito função: correspondência, relação, dependência e variação. Identificou-se que a atividade planejada possibilitou argumentações e discussões entre os estudantes e destes com as pesquisadoras. Por meio dessa interação, os estudantes demonstraram domínio de conversão entre as representações semióticas identificadas na situação apresentada, conseguindo converter as informações em estruturas organizadas e criando esquemas matemáticos para resolução da atividade proposta.

Os ecossistemas brasileiros são uma importante temática que deve estar presente nos currículos escolares. O currículo é uma das partes integrantes da educação formal, constituindo sua função fundamental na sistematização dos conhecimentos, devendo estar presentes no ensino básico e superior. Entendendo a necessidade de analisar a dinâmica dos currículos que constituem os cursos superiores formadores de professores, o presente estudo dedicou-se a investigar a abordagem do Bioma Pampa, um ecossistema considerado negligenciado, como uma possível estratégia de contextualização e interdisciplinaridade para o Ensino de Ciências no curso de Licenciatura em Ciências da Natureza da Universidade Federal do Pampa, Campus Uruguaiana. A pesquisa se caracteriza como um estudo de caso, de cunho qualitativo, estando o processo metodológico baseado na análise documental do Projeto Pedagógico do respectivo curso, através de uma matriz analítica composta por perguntas às quais o documento deve ser capaz de responder. Como principais resultados constatou-se que, apesar de mencionar o Bioma Pampa nos ementários, o documento não fornece referencial teórico e aporte que fundamente as suas menções como temática no contexto em que estão aplicadas. Desta forma, faz-se necessária a atualização do Projeto Pedagógico do Curso e a inclusão do Bioma Pampa como temática de contextualização para o ensino.
Męskości hybrydowe, czyli wilk w owczej skórze. Definiowanie konceptu
Authors: Kluczyńska Urszula
Published: November 2021

Krytyczne studia nad mężczyznami i męskościami oferują coraz większą pulę terminów i kategorii opisujących męskości oraz zależności genderowe. Najbardziej zananą teorią, która zmonopolizowała badania w obrębie studiów, jest teoria męskości hegemonicznej R.W. Connell. Teoria ta została poddana krytyce, która przyczyniła się do wyłonienia kolejnych propozycji opisu męskości. Jedną z takich propozycji są męskości hybrydowe. Celem tekstu jest poszerzenie dostępnych w języku polskim opisów i krytyki koncepcji teoretycznych w obrębie krytycznych studiów nad mężczyznami i męskościami. Autorka skupiła się na przybliżeniu koncepcji męskości hybrydowych. W ramach opisu kategorii męskości hybrydowych autorka wskazała na sposoby definiowania konceptu, opisała konsekwencje hybrydyzacji oraz odniosła się do badań, które wykorzystały tę kategorię analityczną lub których wnioski odnosiły się do męskości hybrydowych. Koncept męskości hybrydowych został również ukazany  na tle wybranych kategorii męskości i poddany dyskusji.

Wywiad z egipskim historykiem Ahmadem Zakarijją asz-Szalakiem na temat sytuacji Egiptu pod okupacją Turcji Osmańskiej, jej negatywnego wpływu na rozwój cywilizacyjny kraju i modernizacji, którą zapoczątkowały rządy dynastii Muhammada Alego. Uczony podkreśla znaczenie kultury tworzonej w okresie rządów monarchii do wybuchu rewolucji 1952 roku dla odrodzenia Egiptu. Argumentuje, że jego tożsamość jest produktem różnych wpływów kulturowych i nie powinna być przez nikogo zawłaszczana.
Paralela Emmanuel–lew i jej znaczenie w programie malarskim serbskich ikonostasów
Authors: Gronek Agnieszka
Published: November 2021

Jedną z wyjątkowych cech programów malarskich nowożytnych serbskich ikonostasów jest obecność w nich tematu Czuwającego Emmanuela, ilustrującego intelektualną paralelę Emanuel - lew. Ideowym źródłem tego obrazu są teksty biblijne i ich interpretacje Orygenesa, Cyryla Aleksandryjskiego, Teodora z Cirrhus, Epifaniusza z Salaminy oraz anonimowego autora Fizjologusa, greckiego bestiariusza z II-IV wieku.

Ikona ta znajduje się w samym środku ikonostasu, najczęściej bezpośrednio nad wrotami królewskimi. W niniejszym artykule podjęto próbę odczytania treści tego przedstawienia. Studia ikonograficzne, ikonologiczne, porównawcze oraz analiza treści tekstów biblijnych i inskrypcji na ikonach doprowadziły do przekonania, że obraz Czuwającego Emmanuela w tym miejscu ikonostasu pełni przede wszystkim funkcje apotropaiczne, tj. opiekuńcze i ochronne. Przestrzeń świątynna podzielona jest na dwie części: sanktuarium i nawę, co oznacza symboliczny podział na świat widzialny i niewidzialny, ziemski i niebiański, cielesny i duchowy. Ikonostas stanowi granicę między tymi dwiema sferami, a królewskie wrota je łączą. Przejścia strzeże obraz "Czuwającego Emmanuela”. Choć w wieku XVIII w serbskim malarstwie cerkiewnym nastąpiły radykalne zmiany formalne, a tradycyjne wzorce zostały zastąpione przez nowe, zachodniego pochodzenia, to oryginalne treści apotropaiczne pozostały.
Репрезентація родинних цінностей у польських паремійних одиницях із семантично протилежними компонентами
Authors: Мороз Тетяна
Published: November 2021

У статті представлено результати дослідження поняття сім’я та основних родинних цінностей у складі польських прислівʼїв та приказок із семантично протилежними компонентами. З огляду на семантику паремій виокремлено групи, які репрезентують образ польської родини – “Чоловік і дружина (стосунки між ними)”, „Батьки і діти (значення батьків для дітей)”, „Батьки і діти (значення дітей для батьків)ˮ, ”Родинні стосункиˮ. Аналіз цих груп показав широту семантичної структури прислівʼїв та приказок з антонімічними компонентами, за допомогою яких відображено стосунки між чоловіком і дружиною, особливості сімейної ієрархії (соціальна роль чоловіка та дружини); суттєву різницю між значенням батька і матері для дитини, зокрема статус та функції батька й матері; особливе значення дітей у житті батьків; стосунки між братом і сестрою та між двома братами, а також образи кровних родичів та свояцтва.
