Self-Reported Perceptions of Online Learning and Observed Online Learning Behaviors: To What Extent Are They Consistent?
Authors: Han Feifei
Published: December 2021

This study investigates to what extent there is an association between students’ self-reported perceptions of online learning and observed online learning behaviors recorded by the learning analytic data. The participants were 319 undergraduates studying an engineering course in an Australian university. Data analyses were conducted using cluster analyses, Hidden Markov Model, one-way ANOVAs, and a cross-tabulation. The relations between students’ self-reported perceptions and their academic learning outcome show that those with positive perceptions tended to have higher scores. The relations between observational online learning behaviors and their academic learning outcome demonstrate that students with most learning sessions achieved more highly. The cross-tabulation finds a significant association between the cluster membership generated by by the self-reported perceptions and observational online learning behaviors. Amongst students who had most study sessions characterized by high percentages of reading and formative states and low percentage of summative states, the proportion of those with positive perceptions (40.2%) was significantly higher than those with negative perceptions (20.0%). Of students who had the least study sessions represented by moderate reading and summative states, and low formative states, the proportion of students with positive perceptions (3.0%) was significantly lower than the proportion of students having negative perceptions (8.7%).
External Factors Explaining Students’ Persistence in Online Courses in Higher Education: A Study Among Two French-Speaking Universities in Canada
Authors: Lakhal Sawsen , Heilporn Géraldine , Khechine Hager
Published: December 2021

The aim of this study was to verify if external factors influence persistence in online courses in higher education. These external factors, borrowed from Kember’s (1995) model, included some students’ characteristics; cost benefits; social integration of adult students (enrolment encouragement, study encouragement, and family support); and external attribution (insufficient time, events hindering study, and distractions). Data were collected among a sample of 835 students from two Canadian French-Speaking Universities (n1 = 468 from University One and n2 = 367 from University Two) using an online questionnaire. The questionnaire included items borrowed from The Distance Education Student Progress (DESP) inventory (Kember et al., 1992). The multiple linear hierarchical regression analysis revealed that students’ characteristics and some of the external factors had an effect on students’ persistence in online courses and that the most important factor in predicting students’ persistence is cost benefits. These analyses were also conducted by university, gender, and age groups. Except for cost benefits, the results indicated different patterns of strength and significant relationships between groups.
Ending Enclosure by Copying the Commons
Authors: Williams Mita
Published: December 2021

In the beginning (of bibliometrics), citation counts of academic research were generated to be used in annual calculations to express a research journal’s impact. Now those same citation counts make up a social graph of scholarly communication that is used to measure the research strengths of authors, the hotness of their papers, the topic prominence of their disciplines, and assess the strength of the institutions where they are employed. More troubling, the publishers of this emerging social graph are in the process of enclosing scholarship by trying to exclude the infrastructure of libraries and other independent, non-profit organizations invested in research.

This paper will outline efforts currently being employed by scholarly communication librarians using platforms built by organizations such as Our Research’s UnPaywall and Wikimedia’s Wikidata Project so that the commons of scholarship can remain open. Strategies will be shared so that researchers can adapt their workflows so that they might allow their work to be copied, shared, and be found by readers widely across the commons. Scholars will be asked to make good choices.
Reframing Web Accessibility in Post-Secondary Education: Examining the Role of the Educator in the Curation and Creation of Accessible Digital Course Content
Authors: Ashbourne Kim
Published: December 2021

Web accessibility is emerging as a key issue and opportunity for educators in post-secondary institutions (Brown, 2018; Gronseth, 2018). Many factors affect web accessibility, yet little literature examines web accessibility factors relative to literacy, pedagogy, course culture, course content curation and information design for learning— areas that rest firmly within an educator’s domain. What facets are specifically relevant to post-secondary educators? The conference presentation, this proceeding, and a subsequent article for the OTESSA journal that addresses the broader construct of digital accessibility, invite critical engagement with web accessibility practices, accessible course content, and the digital accessibility of technology-mediated learning environments. Together and individually, they offer educators various points of entry that are relevant to praxis and seek to ignite discussions and interventions that build educators’ agency and self-efficacy to co-create accessible courses with students with (and without) disabilities.

Published: December 2021

Research objective: in a prospective controlled study to investigate the role of HSP60, GroEl and other infertility factors as predictors of successful IVF outcome. Materials and methods. 106 female patients were divided into two groups: 54 individuals who received conventional treatment for infertility (using ICSI techniques for IVF) and 52 individuals who received conventional therapy with intravenous IgG, enoxaparin and aspirin. All collected blood samples were tested for HSP60 and GroEl antibodies using immunofluorescence and ELISA techniques at the time of admission, after treatment (and before embryo transfer), and after embryo transfer. We analyzed the factors that can be helpful as prognostic parameters to estimate the risk of implantation failure.Results. The risk of implantation failure is predicted when HSP60 level decreases from the first to the second measurement by less than 0.02 optical density units, with a sensitivity of 62% (95% confidence interval (CI) 47.2–75.3), and a specificity of 87.5% (95% CI 75.9–94.8), the positive predictive value was 81.6% (95% CI 68.2–90.2), the negative predictive value was 72.1% (95% CI 64.1–78.8). The GroEl value for the second dimension was more than 0.411 optical density units, which suggests a risk of treatment failure with a sensitivity of 64% (95% CI 49.2–77.1) and a specificity of 85.6% (95% CI 73.8–93.6), the positive predictive value was 80.0% (95% CI 67.1–88.7), the negative predictive value was 72.7% (95% CI 64.5–79.7). The highest (p < 0.05) value was observed at the beginning of treatment, and the lowest (p < 0.05) – during the third measurement.Treatment of the underlying cause of infertility led to a decrease in HSP60 and GroEl levels, which ensured a positive in vitro fertilization result. It was found that HSP60 and GroEl have a strong association with embryo implantation. The risk of implantation failure was strongly associated with twelve factors, the area under the curve (AUC) was 0.85 (95% CI 0.76–0.91).Conclusions. HSP60 and GroEl are good prognostic factors for predicting a successful IVF outcome in patients undergoing infertility treatment. The measurement of these parameters during the initial infertility examination may help in the immediate diagnosis of autoimmune infertility. Embryo implantation is a multifactorial process. The risk of implantation failure should be evaluated with multiple factors (twelve factors).

Published: December 2021

Research objective: to determine the frequency of vitamin D deficiency and insufficiency to identify its association with reproductive hormones in adolescent girls with oligomenorrhea.Materials and methods. The work was carried out according to the results of clinical and instrumental examination of 68 adolescent girls 12–18 years old with oligomenorrhea, who were treated at the Department of Pediatric Gynecology of the State Institution “Institute for Children and Adolescents Health Care of the NAMS of Ukraine”. Patients were divided into two groups depending on the body mass index (BMI): group I – with a body weight deficit (BMI 16.31 ± 0.18 kg/m2), group II – with a BMI within physiological norm (20.0 ± 0.25 kg/m2). All patients underwent a comprehensive clinical and laboratory examination: luteinizing, follicle-stimulating hormones, prolactin, estradiol, testosterone, cortisol, 25(OH)D were determined in blood serum. Multivariate regression analysis was using for analyze the association of gonаdotropic, steroid hormones with vitamin D. The main characteristics of the object discrimination model are presented in the form of tables.Results. The article provides a comparative analysis of the hormonal profile and vitamin D level depending on BMI. It was revealed that a reduced 25(OH)D value was characteristic not only in patients with menstrual dysfunction, but also in peers with normal menstrual function. Schemes that characterize the pituitary-gonadal association with vitamin D were constructed based on the results of multiple regression analysis. Their features were determined in girls with different body weights. In patients with low energy resources there were direct associations between individual indicators of gonadotropins (follicle-stimulating hormone), steroid hormones (estradiol, cortisol) and vitamin D. An inverse association was observed between vitamin D and cortisol and prolactin in girls with balanced energy status.Conclusions. The reduced content of vitamin D is characteristically for patients with menstrual dysfunctions by the type of oligomenorrhea. Associations of gonadotropic, steroid hormones and vitamin D, depending on the energy status (nutrition) of patients with oligomenorrhea were revealed.
Resolution of the 1st Ukrainian expert forum on abnormal uterine bleeding
Authors: - -
Published: December 2021

The menstrual cycle is an important indicator not only of the female reproductive system health but also an integral part of women's health. The issues of therapeutic approaches for menstrual disorders, considering the general trend towards an increase in the proportion of this pathology among the total gynecological disorders in Ukraine, are susceptible and require close attention. The problem of abnormal uterine bleeding (AUB) has a significant impact on women and health care worldwide. Algorithms for the diagnosis and therapy of AUB need to be regularly revised as international recommendations are updated, clinical trials are published, and a new look at pathogenetic mechanisms is made.The prerequisites for holding of this Expert Forum were the updating of the FIGO classification of uterine bleeding in 2018, the NICE guidelines “Heavy menstrual bleeding: assessment and management” in 2018 and 2021, as well as the new conditions of the pandemic era, which has taken its toll on the care of patients with AUB.The Resolution summarized all data unaccounted for in the current clinical protocol for AUB issued in 2016 and updated data from international guidelines and key studies in patients with AUB; highlighted in detail current thinking on the pathogenetic therapy of functional AUB, with an emphasis on chronic AUB associated with ovulatory dysfunction (AUB-O) and endometrial disorders (AUB-E), as the most common; provided modern approaches to the management of chronic AUB associated with non-structural causes (ovulatory dysfunction and endometrial factors), and prevention of acute AUB for implementation in clinical practice and improving the provision of evidence-based medical care and individualized patient care.The Resolution aims to optimize clinical approaches to patient management and ensure therapy personalization, which together will improve the reproductive health and general well-being of Ukrainian women.

Published: December 2021

In a broad sense, insulin resistance (IR) is the impairment of the biological response of target tissues to insulin stimulation. IR plays a leading role in the development of metabolic syndrome, the global prevalence of which continues to grow, despite the significant efforts of medical systems. The multicomponent nature of metabolic syndrome implies its complex and heterogeneous pathogenesis, knowledge about which is annually updated with new details as a result of scientific research.This review systematizes the results of recent studies on risk factors and pathogenetic links in the development of IR, prospects and existing experience of using these data in clinical practice with an emphasis on assessing the level of melatonin and vitamin D. The issue of timely and reliable laboratory confirmation of IR is relevant not only for endocrinologists, but also for specialists in almost all areas. In clinical use apart from indirect methods of IR-assessment like HOMA-IR, there is an informative test intact proinsulin.Recently, the increasing attention of researchers is attracted by such factors of the development of IR as vitamin D deficiency and disturbances in chrono- and biorhythms. Today, their role in the pathogenesis of IR can be considered proven, which makes it possible to consider vitamin D and melatonin as therapeutic agents in an integrated approach to the prevention and correction of IR. Statistical analysis of the research results of the “DILA” Medical Laboratory and clinical data provided by the Department of Endocrinology of the O.O. Bogomolets National Medical University also showed an association of vitamin D and melatonin levels with IR.Thus, a review of scientific sources over the last 5 years clearly demonstrates the growing urgency of the problem of IR and metabolic syndrome, the need to reconsider their management from assessing traditional etiopathogenetic factors (alimentary) to taking into account the maximum spectrum of genetic aspects and exogenous impacts. An important place among the latter belongs to an objective assessment of the vitamin D and melatonin levels for adequate pharmacological correction.
Non-linear Blocking Effects on Suppletive Allomorphy
Authors: DEMİROK Ömer
Published: December 2021

It has been widely observed that suppletive allomorphy (e.g., better blocking *good+er in English) respects some form of locality; however, it is still debated if the relevant metric of locality needs to be stated in linear terms or structural terms (Embick, 2010; Bobaljik, 2012; cf. Moskal and Smith, 2015). This study contributes to this debate by investigating the root allomorphy patterns in Laz, an endangered South Caucasian language spoken primarily in Turkey. In each case of root allomorphy in Laz, the root is required to be linearly adjacent to the morpheme that conditions the allomorphy. Moreover, Laz exhibits (what will be called) non-linear blocking effects on allomorphy: Some prefixes can prevent a suffix from conditioning allomorphy on the root. Importantly, this case constitutes evidence that linear adjacency is not a sufficient condition on suppletive allomorphy and is at odds with the view that the domain of grammar responsible for selecting exponents operates on linearized structures (cf. Embick, 2010).
Resilience in the Context of the Implementation of the EU-Ukraine Association Agreement
Authors: Petrov Roman , Holovko-Havrysheva Oksana
Published: December 2021

This article examines the extent of the practice of resilience in the process of the implementation of the EU-Ukraine Association Agreement (AA). Also, it analyses the main legislative and institutional tools promoting resilience of Ukraine’s market integration with the EU. Two cases are considered in this study. The first case is the launch of negotiations on the EU-Ukraine Agreement on Conformity and Acceptance of Industrial Products (ACAA). The second case is an EU-Ukraine Trade Dispute on Export Woods Ban. In both cases the EU institutions and Ukraine display a high degree of flexibility to pursue a policy of resilience to achieve a high degree of EU Internal Market rapprochement. In the case of Ukraine, the institutional mechanism of the EU-Ukraine AA remains unused as a forum to discuss effectively and to find solutions for impeding problems in the bilateral cooperation agenda. Therefore, a coherent, transparent, and effective institutional cooperation framework in the bilateral EU-Ukraine relations is still needed.
“Publicity” and “Confidentiality in Arbitral Judiciary: Approaches to Understanding and Application
Authors: Yanovytska Anna
Published: December 2021

The growing interest in alternative forms of dispute resolution has prompted attention to the peculiarities of the application of the principles of publicity and confidentiality in the arbitration. It is determined that the observance of the principle of publicityof the legal proceeding is the basis for ensuring justice. However, approaches to the application of this principle in arbitration differ both from the point of view of researchers and within the framework of legal regulation at the national and international levels. Some believe that the application of the principle of publicity will destroy the features of arbitration as such. However, the presented article demonstrates other approaches. The position was supported that the principle of confidentiality should be distinguished from the concepts of “privacy” or “closed trial”. In this context, publicity is often compared to concepts such as “openness”, “clarity” and “transparency” of the proceedings. Of concern is some regulatory restriction on the application of the principle of publicity, which affects the level of awareness of the activities of arbitration courts among the public and lawyers who intend to use alternative forms of dispute resolution. It is hoped that such further research will help solve similar problems.
INTENSITY OF FREE RADICAL PROCESSES IN THE POSTNUCLEAR FRACTION OF RAT KIDNEYS UNDER INFLUENCE OF LASER IRRADIATION AND ω-3 POLYUNSATURATED FATTY ACIDS
Authors: Ketsa O. V. , Marchenko M. M. , Samuliak О. А.
Published: December 2021

Introduction. The effect of laser irradiation on the body can lead to local tissue damage, which will be accompanied by changes in biochemical processes that occur in the kidneys. The direction of these changes is completely unclear, so the study of free radical oxidation of lipids and proteins as the main markers of oxidative stress in the body and their correction by ω-3 polyunsaturated fatty acids (PUFA) remains relevant.
Aim.  To evaluate the intensity of lipid peroxidation and oxidative modification of proteins in the postnuclear fraction of rat kidneys under the action of laser irradiation and additional administration of ω-3 PUFA.
Methods. The studies used white outbred rats, which were irradiated daily for 4 minutes with a laser diode with a wavelength of 650 nm, power of 50 mW in the abdominal cavity at a distance of 10 cm from the skin surface. The state of lipid peroxidation (LPO) was determined by the level of primary, secondary and final products. The intensity of oxidative modification of proteins (OMP) was evaluated by the level of carbonyl derivatives and protein SH-groups. To correct the prooxidant state, the animals were additionally injected with ω-3 PUFA.
Results. Low-intensity laser irradiation has a destructive effect on the cell membranes of the kidneys, which is expressed by an increase in primary, secondary and final products of LPO in phospholipid extracts and an increase in the intensity of OMP. The introduction of ω-3 PUFAs reduces free radical processes in the kidneys of irradiated rats, but this effect depends on the scheme of their introduction. ω-3 PUFAs do not show antioxidant effect under the conditions of their introduction after laser irradiation. Daily administration of ω-3 PUFA two hours before irradiation shows a slight antioxidant effect only in the initial stages of irradiation. Preliminary seven-day administration of ω-3 PUFA before laser irradiation is the most effective, as it helps to reduce free radical processes.
Conclusion. It is established that ω-3 PUFAs are able to have a corrective effect on the action of low-intensity laser irradiation, which depends on the scheme of their introduction. The highest antioxidant effect is observed in groups of animals to which ω-3 PUFA was previously administered before the action of laser irradiation.
THE PUBLICATIONS OF THE MEMBERS OF THE IMPERIAL SOCIETY OF AGRICULTURE OF SOUTHERN RUSSIA IN DEFENCE OF THE ECONOMIC INTERESTS OF THE DNIEPER UKRAINE IN THE 1830'S – 1840'S
Authors: Honcharuk Taras
Published: December 2021

The article focuses on the analysis of the publications of members of the Imperial Society of Agriculture of Southern Russia (with the center in Odesa) and related figures, published on the pages of the “Listki” and later of the “Notes” of the Society and the newspaper “Odesskiy vestnik” in 1830`s – 1840's. It was noted that the authors of these publications belonged to various economic courses from conservative to moderately liberal. It was also pointed out the circulations among the members of the Society the ideas of “physiocrats”, which they themselves understood as a recognition of the priority of agriculture, over all other human activities. The publications whose authors insisted on the necessity for immediate government measures to improve transport connections, especially the deployment of railways and improved the river transport vital to the development of agricultural exports were examined by author. The arguments of the members of the Society in their polemics with the authors of the St. Petersburg “Zemledelcheskaya gazeta”, who unjustifiably criticized the traditional forms of Ukrainian economy and accused the Ukrainian peasants of natural “laziness”, were interpreted too. In addition the author of the research analyzed the publications of the members of the Society, who supported the free trade course. It was concluded that, regardless of the general economic views, the members of the Society mostly grouped around the protection of economic interests of Ukrainian lands.

The article presents publications of the late 19th – early20th centuries, in which museum materials of Ukrainian originare studied and published. This refers to museum catalogs,albums and reports. The purpose of this article is to trace thedynamics of the use of these publications in scientific researchof colleagues during the late 19th – early 21th centuries. Theproposed analysis proved the fact that museographicpublications have acted an important role in scientificresearch for a long time, starting from the moment they werepublished until the present time. It was also found that as ahistorical source, museography was emphasized in threedirections: the basis for conclusions about historical facts; thefoundation for the protection of objects of history and museumresearch; and for museum attribution work. The context of theuse of museum publications has changed. In the 19th century,they were used to show the development of museums in thesouth of the Russian Empire. In the Soviet period, "prerevolutionary" museum publications were perceived as tracesof "bourgeois science." Modern researchers consider museumcatalogs, albums, reports of the late 19th – early 20th centuries as one of the aspects of themanifestation of the process of national revival in Ukraine at the frontier of the century. It was alsonoted that at the end of the 19th and throughout the 20th century, publications of archaeologicalcollections were more popular, especially materials found in the south of Ukraine. In the 21st century,the attention of researchers was attracted by materials from the period of the Cossacks. In general,there was a stable interest in Ukrainian museum publications of the late 19th – early 20th centuries.

La revisión se realizó sobre bases de datos de revistas científicas adscritas a Science Direct, Scopus, Scielo y Redalyc, durante un periodo comprendido entre 2013 y 2020. Dado que el huevo se considera un alimento de alto riesgo para la salud y un producto con una variedad de propiedades funcionales, en los últimos años, se ha identificado una tendencia en aplicar tratamientos térmicos que permitan obtener un producto seguro microbiológicamente para los consumidores y con el menor efecto en dichas propiedades para ser utilizado por la industria. En general, el huevo es una materia prima fácilmente procesable a través de diferentes tecnologías, que permiten obtener productos líquidos o sólidos para ser utilizados en nuevos productos procesados. El uso de estas tecnologías permite reducir los costos operativos y mejorar la calidad del producto.

Authors: Mosquera Sanchez Silvio Andres , Santiago Campo Carlos Holmes , Paz Peña Sandra Patricia , Ruco Sánchez Cristina
Published: December 2021

La  ahuyama  (Cucurbita  moschata)  se  caracteriza  por  su  valor  nutritivo,  especialmente  por  su contenido de vitamina A, carbohidratos, fósforo y minerales. También, por poseer 45 % de carotenoides totales, 66 % de β-caroteno, 33 % de α- caroteno y 44 % de luteína. Su elevado porcentaje de agua cercano al 90 % es propicio para el crecimiento bacteriano y/o fúngico disminuyendo su vida útil. Este estudio evaluó, cada tres días  durante un total de 12, con tres  repeticiones  y  tres  réplicas, las características fisicoquímicas (peso, color, firmeza, tasa de respiración); microscópicas (MOAR y MET), bromatológicas y microbiológicas, de ahuyama variedad bolo verde troceada en fresco.  4 tratamientos: SN (muestra testigo); CV con vinipel; CR con recubrimiento de almidón de yuca y aceite  esencial  de  tomillo al 1 %; y CB con sistema binario  (recubrimiento de fuente natural y vinipel) a una temperatura de 19 °C  y humedad media de 77,75 %. Los tratamientos con película de vinilo arrojaron menor pérdida de peso y  firmeza, menor  tasa  de  respiración y mayor estabilidad en el color, en  tanto  que  las muestras  testigo y recubiertas, arrojaron mayor contenido de azúcares y humedad,  pero menor cantidad de  proteína  y  cenizas.  Adicionalmente,  las  muestras  con  vinipel,  con y sin recubrimiento, registraron un menor crecimiento fúngico.  La ahuyama  troceada  en  fresco  puede conservarse  de  forma  adecuada  mediante  el  uso  de películas de polietileno de baja densidad (vinipel), que permiten retrasar de manera efectiva los procesos de pérdida de calidad inducidos por las operaciones de corte y manipulación.

Authors: Maciel Suely , Ferreira Matheus , Oliveira Guilherme Ferreira de
Published: December 2021

A produção e disponibilização de recursos de acessibilidade, como textos alternativos (Alt), são aspectos necessários para tornar o jornalismo mais acessível. O objetivo deste artigo é comparar a composição de fotografias jornalísticas de viagem com seus respectivos Alt para verificar se a função e/ou conteúdo fotográficos podem ser transmitidos às pessoas com deficiência visual. Para isso, fez-se uma pesquisa exploratória em cadernos de viagem de sites de jornais brasileiros, na qual apenas o conteúdo da Folha de S. Paulo apresentou o recurso em todas as fotos. Fez-se um levantamento das características de composição de três fotos e, com base no Paradoxo Fotográfico de Barthes, comparouse a mensagem imagética com o Alt. Observa-se que os Alt usados não substituem adequadamente as fotos, comprometendo a compreensão total por parte das pessoas com deficiência visual.The photographic Message of Travel Journalism: qualitative methodology for Alternative Texts evaluationAbstractThe production and availability of accessibility resources, such as alternative texts (Alt), are necessary aspects to make journalism more accessible. This article compares the composition of travel news photographs with their respective Alt to verify whether the photographic function or content is accessible to visually impaired people. Exploratory research was carried out in travel sections of Brazilian news websites, in which only the Folha de S. Paulo presented the resource. Hence, the composition characteristics of three photographs have been assessed and based on the Barthes Photographic Paradox, there was an examination between the photos message and their Alt. As a result, the Alt used does not adequately replace the images. Such inadequacy compromises the understanding on the part of visually impaired people.Keywords: Travel Journalism; accessibility; alternative text; visual impairment.

“Queda Livre”: Conceitos de Cidadania em Episódio da Série Black Mirror
Authors: Rodrigues Sandro Lima , Araujo Denize Correa
Published: December 2021

As inovações tecnológicas otimizaram novas possibilidades de interações pessoais no ambiente virtual, causando, no entanto, significativas mudanças comportamentais em certas ocasiões. O objetivo deste artigo é identificar as correlações das novas tecnologias com a realidade contemporânea, tendo o episódio intitulado “Nosedive” (em portuguêsbrasileiro,“Queda Livre”) da terceira temporada da série “Black Mirror” (Brooker, 2016) como contexto representativo de uma sociedade cada vez mais conectada em ambientes virtuais, exibindo comportamentos que por vezes geram dissonâncias cognitivas nos conceitos de cidadania. Após a análise com metodologia dialética, aproximando o episódio em análise com o que a sociedade tecnológica está exibindo, a conclusão é que o episódio “Queda Livre” está potencializando a cultura do impressionar, que retrata o desespero de indivíduos por serem notados e aceitos em uma sociedade, incluindo a síndrome de FOMO (Fear of Missing Out/medo de ficar de fora), patologia cada vez mais presente, que questiona conceitos de cidadania em redes sociais e ambientes virtuais. O referencial teórico para a análise inclui conceitos de Zygmunt Bauman, Massimo Di Felice, Pierre Lévy, Andrew Keen e SherryTurkle.“Nosedive”: Citizenship Concepts in Episode of the Series Black MirrorAbstractThe technological innovations have optimized new possibilities for personal interactions in the virtual environment, causing, however, significant behavioral changes on occasion. The aim of this article is to identify the correlations of new technologies with contemporary reality, with the episode entitled “Nosedive” (in Brazilian-Portuguese, “Free Fall”) from the third season of the series “Black Mirror” (Brooker, 2016) as context representative of a society increasingly connected in virtual environments, exhibiting behaviors that sometimes generate cognitive dissonance in the concepts of citizenship. After analyzing with dialectical methodology, bringing the episode under analysis closer to what the technological society is exhibiting, the conclusion is that the episode "Free Fall" is enhancing the culture of impressing, which portrays the despair of individuals for being noticed and accepted in a society, including the syndrome of FOMO (Fear of Missing Out/fear of being left out), an increasingly present pathology that questions concepts of citizenship in social networks and virtual environments. The theoretical framework for the analysis includes concepts by Zygmunt Bauman, Massimo Di Felice, Pierre Lévy, Andrew Keen and SherryTurkle.Keywords: Behavior; communication; social nets; virtual scenery; citizenship.

Niniejszy artykuł przedstawia projekt pilotażowy, jaki został przeprowadzony podczas lektoratów języka polskiego akademickiego dla cudzoziemców na Uniwersytecie Kardynała Stefana Wyszyńskiego w Warszawie, dla którego inspiracją była metoda PhotoVoice.
Język medycyny (medyczny) – dyskusja nad definicją
Authors: Oczko Paulina
Published: December 2021

W niniejszym tekście podjęta została dyskusja nad zdefiniowaniem pojęcia polski język medycyny (medyczny) dla celów glottodydaktyki. Artykuł składa się z sześciu części. W pierwszej kolejności omówiono dotychczasowe założenia teoretyczne nauczania polskiego języka medycyny (medycznego). Następnie zaprezentowano sposoby opisu języka medycznego na gruncie glottodydaktyki angielskiej, francuskiej i niemieckiej. W kolejnej części znalazły się metodologiczne i lingwistyczne założenia materiałów glottodydaktycznych przeznaczonych do kształcenia specjalistycznego. W czwartej części zarysowano definicję pojęcia medycyny w kategoriach semantycznych oraz syntaktycznych. Piąta część poświęcona została legislacyjnemu rozumieniu polskiego języka medycyny (medycznego). Rozważania te prowadzą do prezentacji konkluzji i wskazań dla glottodydaktyki polonistycznej w części szóstej. Wyniki analiz wykazały, iż zagadnienie opisu języka polskiego do celów specjalistycznych jest bardzo złożonym procesem. Niezbędne są dalsze badania, dotyczące m.in. warstwy stylistycznej polskiego języka medycyny (medycznego), kompetencji socjolingwistycznej, socjokulturowej i realioznawczej.
Eduroom na lekcji języka polskiego jako obcego – wirtualny pokój zagadek
Authors: Kaźmierczak Paulina
Published: December 2021

Celem artykułu jest przedstawienie możliwości wykorzystania techniki pokoju zagadek w glottodydaktyce polonistycznej. Prześledzony zostanie proces adaptowania na potrzeby edukacyjne tej popularnej formy rozrywki, znanej powszechnie w anglojęzycznym wariancie jako escape room. Konieczność zmiany formy zajęć językowych z pracy stacjonarnej na zdalną skutkuje wprowadzaniem wciąż nowych pomysłów na przyciąganie uwagi słuchaczy w trakcie lekcji. Doskonałym sposobem jest korzystanie z możliwości, jakie oferuje dostęp do nowych technologii. Potencjał różnorodnych platform, aplikacji, narzędzi online jest szeroko opisywany na grupach, które zrzeszają nauczycieli korzystających z portalu Facebook. Nie sposób pominąć fakt, że skarbnicą wiedzy w tym zakresie są rady anglistów i polonistów, którzy pracują głównie z polskimi dziećmi. Jednak wskazane przez nich narzędzia można z powodzeniem adaptować również na potrzeby zajęć z cudzoziemcami – praktycznie na każdym poziomie językowym i niezależnie od wieku lub narodowości. W niniejszym artykule poświęcono szczególną uwagę aplikacjom: Genial.ly, Microsoft Teams oraz Sutori.
