Use of the MAIEA assay to demonstrate that Fy3 is on the same glycoprotein as Fy6, Fya, and Fyb
Authors: Tzeng J. , Dodd R. , Mallory D. 
Published: May 2021

Abstract
The monoclonal-antibody immobilization of erythrocyte antigens (MAIEA) assay is a technique that detects trimolecular complexes formed by a human antibody and a mouse monoclonal antibody with specific red cell epitopes. This enzyme-linked immunoadsorbent assay test gives a positive reaction when two different epitopes on the same membrane protein are separately recognized by human and mouse antibodies. In this study, the MAIEA test was used to determine if the Duffy system antigen Fy3 is on the same membrane protein as Fy6. The well-established location and relationship of Duffy blood group antigens Fya, Fyb, and Fy6 were again confirmed by the MAIEA assay, and those facts were used to standardize a variation of the assay to establish the relationship between Fy3 and Fy6 using red cells with various Fy phenotypes. The MAIEA assay generated high absorbance values when Fy6 and Fya (or Fyb) antigens were evaluated. Similarly, high absorbance values were seen when Fy3 and Fy6 antigens were tested using Fy(a+b+), Fy(a+b–), and Fy(a–b+) red cells. The MAIEA assay is a valid technique for detecting Duffy system antigens. By this technique, it was shown that Fy3 and Fy6 antigens are carried on the Duffy glycoprotein D and by extension that Fy3 is also located on the Duffy glycoprotein D.
Detection of anti-D following antepartum injections of Rh immune globulin
Authors: Kennedy M.S. , McNanie J. , Waheed A. 
Published: May 2021

Abstract
Antepartum prophylaxis using Rh immune globulin (RhIG) at 28 weeks of gestation is routine in unsensitized Rh-negative women. As various sources state that anti-D may be detected up to 6 months after administration, we reviewed the medical and laboratory records of all Rh-negative women who delivered at our institution during 1995. For 385 evaluable women, only 137 (35.6%) had anti-D demonstrable in their sera at delivery; 97.8 percent of these delivered within 75 days after administration of RhIG. Of 248 women (64.4%) who delivered in < 76 days after administration of RhIG, 134 (54%) had demonstrable anti-D. For 123 women who delivered between 76 to 95 days after RhIG, only 3 (2.4%) had demonstrable anti-D. Of 14 women who delivered more than 96 days after RhIG, none had anti- D at delivery. These data show that the 300-μg dose used in the United States may not be adequate for antepartum protection and that the detection of anti-D more than 100 days after the administration of RhIG should be viewed with suspicion.
Evaluation of column technology for direct antiglobulin testing
Authors: Moulds J.M. , Diekman L. , Wells T. D. 
Published: May 2021

Abstract
Preliminary reports have suggested that microcolumn technology might be too sensitive for direct antiglobulin testing (DAT). We studied 228 samples from patients with autoimmune diseases and 30 samples from healthy controls to determine the sensitivity of column techniques. Both Sephadex® gel and protein A/G columns were compared with manual methods using rabbit or murine polyspecific reagents. Of the 187 samples that were negative by both manual methods, an additional 29 (15%) and 42 (22%) samples gave weakly positive reactions with the Sephadex® and protein A/G bead columns, respectively. Subsequently, there was poor correlation between manual and column techniques (r = 0.40–0.61). Acid eluates from these samples were negative. We concluded that the column technology may detect too many weakly positive DATs that are clinically insignificant.
A Virtual Reality Resident Training Curriculum on Behavioral Health Anticipatory Guidance: Development and Usability Study
Authors: Herbst Rachel , Rybak Tiffany , Meisman Andrea , Whitehead Monica , Rosen Brittany , Crosby Lori E , Klein Melissa D , Real Francis J 
Published: May 2021

Background
Behavioral health disorders have steadily increased and been exacerbated by the COVID-19 pandemic. Though behavioral health disorders can be successfully mitigated with early implementation of evidence-based parent management strategies, education for pediatric residents on behavioral health anticipatory guidance has been limited to date, with training challenges compounded by the physical distancing requirements of the COVID-19 pandemic. Virtual reality (VR) simulations provide an opportunity to train residents on this complex competency by allowing deliberate practice of necessary skills while adhering to current social distancing guidelines.

Objective
This study explored the usability of a VR-based behavioral health anticipatory guidance curriculum for pediatric residents.

Methods
This mixed methods study included 14 postgraduate third-year pediatric residents who completed the behavioral health anticipatory guidance VR curriculum. Residents completed the MEC Spatial Presence Questionnaire to assess immersion in the virtual environment. Semistructured interviews were used to elucidate residents’ perspectives on the curriculum’s content and format. The interviews were analyzed using conventional content analysis.

Results
Quantitatively, residents reported a high degree of immersion, spatial presence, and cognitive involvement. Most residents (11/14, 79%) agreed or strongly agreed that it seemed as though they took part in the action of the simulation. Qualitatively, two themes emerged from the data: (1) the curriculum expands behavioral health anticipatory guidance and motivational interviewing knowledge and skills and (2) VR technology is uniquely positioned to develop competence. These themes revealed that the curriculum expanded their current level of knowledge and skill, addressed training gaps, and was applicable to all residents. Additionally, residents experienced VR as immersive, feasible, realistic to the clinic setting, and a safe space to practice and learn new skills.

Conclusions
Pilot data indicates that VR may be an effective tool to teach pediatric residents behavioral health anticipatory guidance, meeting a current gap in medical education training. This VR curriculum is particularly relevant in the context of the COVID-19 pandemic given the increased behavioral health concerns of families.

Published: May 2021

The specificity of the development of the geographical and cultural space of Egypt in the poetry of the Silver Age at the time when the “Russian” poetic Egypt was born as a system of leitmotifs, imagestopos and a specific lexicon is described. It is noted that in modern literary criticism, in comprehending the geopoetics of a regional text, works devoted to the European continent, in particular, geopoetic regional models of Russian literature, have been most fully investigated. The relevance of the study is seen in the need to comprehend and analyze the geopoetics of Egypt and, more broadly, Africa as a sacred geocultural space. The textual fragments of poetic works by K. Balmont, V. Bryusov, I. Bunin, N. Gumilyov, V. Khlebnikov, representing stable geospatial images and symbols of Egypt, are analyzed. The authors come to the conclusion that the poetry of the Silver Age combines geocultural images and symbols with mythological motives, which gives the topos of Egypt a geosophical meaning. The analyzed material made it possible to show the generalized artistic structure of the geopoetic representation of Egypt in the poetics of the Silver Age and to highlight the spatial geocultural dominants: the Nile, Africa, the desert, the Sphinx, Egyptian heroes as images-topos, the Arab East.

Authors: Bacoş Ioan-Bogdan , Gabor Manuela Rozalia 
Published: May 2021

Abstract
Daily exposure to ambient air pollutants harms human health and the environment. Even though in recent years air quality is a taboo subject discussed and researched by many interested areas, pollution indices often exceed the pollution norms imposed by the authorities in major European cities. In response to these environmental problems, the European Union has created a body of legislation on pollution indicators. On the other hand, World Economic Forum promote the travel tourism competitiveness index (including the pillar of environmental sustainability). The purpose of this paper is to present and analyse the indicators from the environmental sustainability pillar within TTCI (Travel and tourism competitiveness index) and the air pollution indicators, respectively the air quality standards and the pollution norms. As a short result, România exceeds at some indicators and has a lot to improve at the others (Enforcement of environmental regulations).

Published: May 2021

AbstractAny initial product started from a more or less flexible idea, or a patented idea transposed into a manufactured product. This idea takes a new development following the study of the marketing market, analysis studies and all we need for technological opportunity, outlining at the same time stage by stage the prototype concept. The prototype variant is again subjected to a systemic analysis that defines and optimizes the final product, as well as the technological flow associated with the entire manufacturing process applied on the concept. The paper proposes a synthesis analysis on innovative conceptual design. The case study presented in this paper shows a reserch study applied on the industrial product for which the patent was obtained, respectively a double compartmented thermos container [17].

Discursive Representations of Education for Sustainable Development in Policy Documents by English Medium Instruction Schools in Estonia and Norway
Authors: Kapranov Oleksandr 
Published: May 2021

AbstractThis article introduces and discusses a study that aims at illuminating discursive representations of education for sustainable development (henceforth – ESD) by means of compiling and analysing a corpus of policy documents written by English medium instruction (EMI) secondary schools in Estonia and Norway, respectively. Informed by the constructivist approach (Foucault, 1981), discursive representations of ESD in the study were operationalised as discursive strategies that were employed in naming, referring to, and providing an evaluative perspective to ESD-related topics. In this study, the corpus of policy documents published by EMI secondary schools in Estonia and Norway was collected in order to analyse discursive representations of ESD by means of applying a qualitative content analysis. The results of the analysis indicated that the discursive representations of ESD were similarly construed in policy documents written and communicated by EMI secondary schools in Estonia and Norway. Those findings were further discussed in the article in conjunction with their didactic implications.

Published: May 2021

Abstract
Lifelong learning emerges as an important dimension in the implementation of sustainable education policies of countries. The conception of developing citizenship competencies, which is at the centre of social studies, plays an important role in shaping the lifelong learning process. The purpose of this study is to analyse the lifelong learning tendencies and teacher self-efficacy levels of social studies teacher candidates in terms of different variables and to determine the relationship between social studies teacher candidates’ lifelong learning tendencies and teacher self-efficacy levels. The study group of the research consists of 307 social studies teacher candidates studying at the education faculty of a public university in the 2016–2017 academic years. The data collection tools used in the research, which was designed in relational survey model, are “Lifelong Learning Tendency Scale” developed by Diker Coşkun (2009), “Teachers’ Sense of Efficacy Scale” adapted into Turkish by Çapa, Çakıroğlu and Sarıkaya (2005) and a Personal Information Form prepared by the researchers. The data of the study are analysed using SPSS 24 statistical software. As a result of the research, it is found that the lifelong learning tendency levels of the social studies teacher candidates are high and their teacher self-efficacy levels are very high. Lifelong learning tendencies and teacher self-efficacy levels of teacher candidates show statistically significant differences in terms of grade level, and taking education for personal and professional development. It is concluded that teacher self-efficacy levels of teacher candidates are a significant predictor of their lifelong learning tendencies.
The Effect of Sustainable Leadership Behaviors of School Principals on Teachers’ Organizational Commitment and Job Satisfaction
Authors: Çayak Semih 
Published: May 2021

Abstract
Sustainable leadership is a field of research in which a lot of research has been done recently. In this study, the effects of sustainable leadership behaviors of school principals on teachers’ organizational commitment and job satisfaction were examined based on teachers’ opinions. The sample of the study consists of 338 teachers working in three districts of Istanbul. Sustainable Leadership Scale, Organizational Commitment Scale and Job Satisfaction Scale were used in the research. Research data were analysed by arithmetic mean, standard deviation, correlation analysis and stepwise regression analysis. According to the findings, teachers’ organizational commitment, job satisfaction, and their perceptions regarding sustainable leadership behaviors of school principals were found to be at a high level. As a result of the stepwise regression analyses, the economic sustainability sub-dimension of the sustainable leadership scale was found to predict teachers’ job satisfaction. On the other hand, it was determined that the managerial and social sustainability sub-dimensions significantly predicted teachers’ organizational commitment. The findings obtained were discussed in the light of the related literature and suggestions were presented.
From the “Greta Thunberg Effect” to Green Conversion of Universities: The Reconstructive Praxis of Discursive Mobilizations
Authors: Feldman Jonathan Michael 
Published: May 2021

Abstract
This paper investigates how one could envision a discursive mobilization process to transform protest movements into agents that help reconstruct the universities as agents supporting material mobilizations leading to ecological reconstruction. After reviewing universities’ ecological footprints, the author shows how theories of mobilization and conjunctures could contribute to understanding how this transformation could occur. Discursive mobilizations advance values or ideas but stop short of innovation and production system changes. Material mobilizations affect deployment of human, technological, industrial and financial resources. Conjunctures involve linkages of political activity to spaces implicated in both kinds of mobilizations in a given historical time frame. The study shows many nations having both extensive climate activism and concentrations of university students creating a possibility for greening education centers based on various models for doing so. Yet, two key problems emerge. First, some nations lag in climate activism. Second, interest in a Green Deal or Green New Deal does not always match the level of attention to leading activist Greta Thunberg. The paper illustrates how such problems can be addressed by university-based campaigns linking activist cohorts, mobilization supporting green conversion of higher education and solidaristic, mutual aid exchanges among regions.

Authors: Kotnik Tina , Moreno Javier , Šoba Barbara , Krt Brane , Skvarč Miha , Vergles Rataj Aleksandra , Gorišek Bajc Maja , Ravnik Verbič Urša 
Published: May 2021

Abstract

Introduction
Leishmaniasis is a life-threatening zoonosis of which dogs are the major reservoir and sandflies are the vectors. Until now, the prevalence of canine leishmaniasis (CanL) in the Slovenian dog population was unknown.

Material and Methods
Epidemiological data, eye swabs and blood samples were taken from 465 dogs born in Slovenia and older than one year. Commercial ELISA kits and real-time PCR were used. For ELISA-positive samples, an immunofluorescence antibody test (IFAT) was performed. Descriptive statistics were used to characterise the samples. The one-sample nonparametric chi-square test was used to test whether the categories of a variable were equally distributed.

Results
A 59.9% proportion of the recruited dogs had travelled to endemic regions and 62.1% of them had not been protected by insect repellents. Skin symptoms that might be CanL-related were described in 109 of the dogs’ histories (23.4%), inappetence and/or weight loss in 25 (5.4%), and anaemia, intermittent fever, and/or lymphadenopathy in 19 (4.1%). At the time of recruitment, all dogs were asymptomatic. All samples were PCR negative, nine (1.9%) were ELISA positive, but none were IFAT positive. Five of the nine ELISA-positive dogs were non-travellers.

Conclusion
We conclude that the seroprevalence of canine leishmaniasis of 1.9 % in the autochthonous Slovenian dog population may pose a risk of endemic spread of the disease.
Perspetivar a Integridade Depois do Fim da Natureza
Authors: Carvalho Magda Costa 
Published: May 2021

Abstract
The expression “end of nature” has been coined by American environ-mentalist Bill McKibben is his 1989 famous book, The End of Nature. Since then, the philosophical implications of such an obituary have been explored, mainly on an ethical perspective over the environment. The conceptual end of nature is one of those implications, in the context of a post-naturalistic environmental philosophy. Our purpose is to build upon the ambiguities of “nature” and reframe some readings of the concept of “integrity” as a guiding principle in the relation between human beings and the environment.

Authors: Dudziak Agnieszka , Caban Jacek 
Published: May 2021

Abstract
The introduction of a city bike system, which has become a complement to the public transport system in large cities and mainly in the most crowded city centers, seems to be a very good solution, which may contribute to reducing urban congestion, air pollution, and noise level. In many situations, bicycle transport can solve the deficiencies in public transport, e.g. at nights, during holidays and on days when bus services are operated to a limited extent. The article presents the functioning of the city bike system in Lublin implemented at the end of 2014, including basic information on the system, its advantages and disadvantages, as well as the existing infrastructure and development prospects.
Effect of Cooperation with Universities on the Innovativeness of Tourism Enterprises
Authors: Olszewski Marcin 
Published: May 2021

Abstract

Introduction. Tourism enterprises operating in a dynamic environment mitigate the erosion of competitive advantages by introducing new products, processes or marketing activities. Universities may serve as one of the essential sources of knowledge, enabling tourism enterprises to implement innovations. The article aims to identify the importance of cooperation with universities in driving innovation in tourism enterprises.

Material and methods. To achieve the aim of the paper, an empirical study was carried out on a sample of 383 hotels and tour operators.

Results. As a result, it was found that universities play a relatively minor role in innovation implementation and for inspiring innovative activity. However, the role of universities is highly diversified. For almost one-third of the entities, universities are important for innovative activities – they play a greater role in large entities, belonging to chains and operating longer on the market. It has also been identified that incremental and marketing innovations are most frequently created due to cooperation.

Conclusions. Results indicate that for increased universities’ role in innovation, companies’ resources and absorption capacity are required. The article also suggests further directions of research on relations between universities and tourism enterprises.
