Les projets de formation à distance : vecteurs de conflits en milieu de travail?
Authors: Bourcier Natalie , Basque Josianne
Published: April 2021

L’élaboration de formations à distance constitue une tâche complexe d’ingénierie pédagogique comportant de nouveaux défis pédagogiques, technologiques et organisationnels. Les pratiques de travail se développent graduellement en ce domaine, mais demeurent encore peu établies dans les divers milieux s’y adonnant. Ce contexte de travail est-il susceptible de favoriser l’émergence de conflits au sein des équipes de travail? Nous avons cherché à répondre à cette question en menant un sondage en ligne auquel ont répondu 80 professionnels ayant participé, à divers titres et dans divers milieux, à des projets de conception de formations à distance. Les résultats révèlent que des situations conflictuelles y sont effectivement observées. Ils fournissent un éclairage sur leur fréquence, sur les objets sur lesquels elles ont porté ainsi que sur leurs effets. Ces situations conflictuelles, si elles sont mal gérées, sont susceptibles de compromettre la qualité des formations à distance.
Synthesis, characterization and application of a bio-derived ZnO nano-powder from spinacia oleracea leaf extract for the removal of BOD and COD from tannery wastewater

Published: April 2021

Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) as biological and chemical pollutants of wastewater are renowned environmental problems.  A study of the performance of BOD and COD degradation via adsorption was undertaken using Bio-derived ZnO nanopowder (ZnO-NP), synthesized using leaf extract of Spinacia oleracea, and Zn (NO3)2 at 500 0C, following a simple and green approach. XRD, SEM, FTIR, EDS and BET analysis were used to characterize the nano-adsorbent. EDS spectrum recorded elemental weight compositions of 67.33% and 32.67% for Zn and O, while the FTIR absorption peaks revealed the presence of Zn-O–H and Zn-O. Surface area analysis revealed the mesoporous structure of the ZnO-NPs. The reduction efficiency of the ZnO-NPs was evaluated in the presence of raw tannery wastewater by application of treatment time and adsorbent dosage as parametric factors; results obtained were compared to environmental regulatory limits (WHO and NESREA). Contact times reported removal efficiencies of 81.5-90.8 % and 12.8-50 % for BOD and COD, while adsorbent dosage-influenced BOD and COD removal at an optimum contact time of 30 minutes was found to be 79.2 - 97.5 % and 27.8 to 55.6 % respectively. This study reveals that ZnO nanopowder is better applied as BOD reductants over COD for spent tan liquor.
The observation of Angegh–Vulture (Cygnus) constellation in Armenia 32 000 years ago
Authors: Malkhasyan H. A.
Published: April 2021

The "Karahunge Observatory" or "Zorats Karer" megalithic monument-complex has been little studied and till today the opinions of different scholars on the age of its construction and significance vary widely. In this article, using astronomical and geometric methods, we have tried to show that this ancient astronomical observational complex could have been built only 32300 years ago by the Angegh-Vulture (Cygnus) constellation model, when the declination of the Sadr star corresponded to the local latitude. It has also been attempted to substantiate the direct link between the constellation and the structure in several respects, in particular, it has been shown that 7800 years ago, some changes were made to the structure, the opening of some stone holes, and the observations of some of the stars of the Angegh-Vulture (Cygnus) constellation. At the same time, however, the original layout-composition of the complex and its contents have been preserved.
Concept of scanning imaging device for optical telescopes
Authors: Papoyan A. V.
Published: April 2021

We propose an approach of a focal plane imaging device for a telescope, which is based on spatially-scanned solitary photodetector, and can be used as an alternative to matrix detectors (CMOS or CCD). This approach allows to set efficient sensor size, pixel resolution, sensitivity and recording time on customer demand. Technical feasibility of up to 200 pixel/mm (5000 ppi) spatial resolution for focal field of up to astronomical photographic plate size, with the detection noise-equivalent power of 3 x 1015 W⁄√(Hz ) and the measurement time of ≈ 1 minute per megapixel is justified.
Studies of Seyfert galaxies in Fesenkov Astrophysical Institute
Authors: Denissyuk E. , Valiullin R. , Omarov CH. , Shomshekova S. , Krugov M. , Omar B.
Published: April 2021

This article provides an overview of the main research results of a large group of Seyfert galaxies, carried out at Fesenkov Astrophysical Institute (FAI) over the past 50 years. Spectral observations have been performed since 1970. At an early stage, a three cascade image-tube (UM-92) was used as a radiation receiver. In the 1990s, the equipment was modernized, and at present, the modern CCD cameras are used as radiation detectors at the output of spectrographs. The results of observations were used to determine the absolute fluxes of the emission lines and to study their profiles. Several additional emission features were detected on the wings of the broad emission lines Hα in the spectra of two galaxies NGC 4151 and Ark 120. These features are emitted by compact ionized objects, rotating in the field of Central Body (CB). Photometric observations of Seyfert galaxies have been carried out at FAI since 2010. Light curves of more than 20 Seyfert galaxies have been obtained. In particular, the light curves of the galaxy NGC 4151, obtained last years, shows that an active stage of its nucleus took place in 2015-2016, when the brightness increased by 0m.5 in the V filter, and by almost 2m in the R filter. Then, in 2018-2019 there was a rather sharp decline of brightness, and B V R magnitudes returned to their minimal values.

Published: April 2021

Merkuri yang dikenal dengan air raksa telah menyebabkan kematian lebih dari 1000 orang di Jepang pada tahun 1968 yang dikenal dengan Minamata disease. Masuknya merkuri ke dalam tubuh manusia melalui pencemaran merkuri pada kasus Minamata disease ini juga telah mengakibatkan belasan ribu orang Jepang menderita kerusakan fungsi saraf otak, kerusakan fungsi genetik yang akhirnya menyebabkan kelumpuhan dan cacat turunan. Kasus yang serupa terulang kembali di Iran pada tahun 1971 yang menyebabkan lebih dari 10.000 kehilangan nyawa dan kira-kira 100.000 orang menderita penyakit seperti yang terjadi di Jepang. Dua bencana tragis yang diakibatkan oleh pencemaran merkuri ini merupakan pelajaran berharga bagi kita untuk lebih mengenal merkuri dan mewaspadai akan keberadaan merkuri dalam kehidupan kita. Buku ini telah direvisi menjadi cetakan kedua dengan menambahkan materi tentang pencemaran perairan. Penambahan materi ini dibutuhkan karena pencemaran perairan oleh komponen pencemar termasuk merkuri merupakan mata rantai yang tidak dapat dipisahkan dari merkuri dan keberadaannya. Selain itu, penambahan materi tersebut juga diperuntukan untuk kebutuhan buku ajar yaitu materi pencemaran air seperti komponen-komponen pencemar air, indikator pencemaran air dan efek pencemaran perairan terhadap lingkungan dan manusia, termasuk di dalamnya tentang keberadaan merkuri sebagai pencemar perairan.

Turkish Ontological Security In The Early Republic Era: Identity, Regime, and State
Authors: BÖLÜKBAŞI Yusuf Ziya , YÜCEL Gökberk
Published: April 2021

This study examines under which factors of Turkey’s ontological security has been formed and how it has been occurred in the early period of the Republic of Turkey. The main claim of the study is that the national identity, the nation-state, and the Republican regime are inseparable and complementary parts of the Turkish ontological security. This study applies the historical analysis method. In the early period of the Turkish Republic which can be deemed as a process of structural and fundamental changes, Turkey's security concept consists of not only border security. The political regime as a continuation of the aim of protecting the Republic's revolutions, including national sovereignty and secularism, and westernization, constituted the prominent factor of Turkish ontological security. Having said that, considering the new geography vision, policies towards Islamic geographies and Central Asia were considered as revisionist and it was aimed that the protection of the status quo both in and outside the country. In accordance with the territorial state model, the Turkish biographical story was reconstructed with the nation-state models as the framework of the national society and the national society itself, and therefore it was accepted as the integral parts of the Turkish ontological security.
Fransa’nın 1860 Lübnan Krizine Müdahalesi
Authors: YAMAN Zeynep , TOPALOĞLU Bekir Sadık
Published: April 2021

XIX. yüzyılda Osmanlı Devleti uluslararası koşullar ve dış baskılar nedeniyle kendi coğrafyasında meydana gelen huzursuzluklarda ekseriyetle yabancı aktörlerin müdahalelerine maruz kalmıştır. Fransız hükümetinin çatışan taraflardan biri lehine müdahalede bulunmak istediği 1860 Cebel-i Lübnan Krizi, yerel bir huzursuzluğun uluslararası bir soruna dönüşmesi durumuna belirgin bir örnek oluşturmaktadır. Cebel-i Lübnan’da köylü ayaklanması olarak başlayan huzursuzluk 1860 yılı itibariyle Dürzîler ve Marunîler arasında bir etnik hesaplaşmaya dönüşmüştür. Dürzîlerin Hristiyan nüfusa karşı katliamlara girişmesi, huzursuzluğun Şam’a kadar yayılması ve Osmanlı güçlerinin olaylar karşısındaki yetersizliği Batı dünyasında infiale sebep olmuştur. Fransa bölgeye bir sefer düzenleme kararı almıştır. Osmanlı hükümeti de dönemin Dışişleri Bakanı (Hariciye Nazırı) Fuad Paşa’yı geniş yetkilerle donatarak bölgeye göndermiştir. Fuad Paşa’nın bölgeye intikaliyle olaylar hızlıca son bulmuş ve Fransız birlikleri Osmanlı güçlerine yardımcı olmakla yetinmiştir. Bu çalışmada 1860 Cebel-i Lübnan Krizine müdahale etmeye gelen Fransız seferinin rolü tartışılacaktır. Seferin Fuad Paşa’nın heyetiyle ilgisi ve olayların akışındaki etkisi gibi konular ele alınacaktır. Konuyla ilgili arşiv metinleri, olaylar üzerine yoğunlaşan o dönemde yaşamış araştırmacıların eserleri ve süreli gazeteler bu çalışmanın ana kaynakları arasındadır.
Yerel Yönetimlerde E-Belediye Uygulamaları: Büyükşehir Belediyeleri Üzerine Bir İçerik Analizi
Authors: KARATAŞ Eren , TARHAN Ahmet
Published: April 2021

Türk kamu yönetiminde belediyeler, toplumsal hayatın gelişmesine ve değişmesine paralel bir şekilde örgütsel yapılarında ve toplumsal hayat içerisindeki yerlerinde çeşitli değişimler yaşamıştır. Vatandaş ve belediyeler arasındaki mekânsal ve toplumsal yakınlık, belediyeleri merkezi yönetim içerisinde tamamlayıcı bir unsur olarak konumlandırmaktadır. Yaşanan bu gelişmeler bilgi ve iletişim teknolojilerinin de gelişmesiyle beraber yönetimsel anlamda çeşitli sorunları beraberinde getirmiştir. Türk kamu yönetiminde, yönetim ve ilgili kamuları arasındaki etkileşimi ve iletişimi olumsuz yönde etkileyen en önemli sebepler olarak geleneksel yönetim anlayışının doğasında var olan kağıt temelli, formalitelere dayanan ağır işleyen bürokratik yapı olarak ön plana çıkmaktadır. Özellikle 1980’li yıllardan itibaren bilgi ve iletişim teknolojilerinde yaşanan gelişmeler kamu yönetimindeki hizmet sunumunda radikal değişimlere yol açmıştır. Bu doğrultuda ulusal anlamda e-devlet; yerel anlamda ise e-belediye uygulaması etkin ve verimli hizmet amacıyla modern yönetim anlayışını gerçekleştirmede hayati bir rol üstlenmektedir.Araştırma kapsamında Türkiye sınırları içerisinde bulunan 30 büyükşehir belediyesinin sunduğu “e-hizmetler” 02 Aralık 2020- 08 Aralık 2020 tarihleri arasında hem kurumsal web sayfaları üzerinden hem e-devlet platformu üzerinden içerik analizi yöntemine tabi tutularak literatürde e-devlet olgunluk modeli/gelişim aşamaları olarak adlandırılan bilgilendirme, etkileşim, işlem ve bütünleşme aşamaları kapsamında incelenmiştir. Elde edilen sonuçlara göre belediyeler ilgili paydaşlarına yönelik çeşitli uygulamalar sunmakta ve bu uygulamalara kurumsal web sayfalarında birbirine benzer isimlerle yer vermektedir. Ek olarak belediyeler bilgilendirme, etkileşim ve işlem aşamalarına yönelik hizmetleri kurumsal web sayfalarında büyük oranda sunduğu görülürken; e-devlet platformu üzerinde etkileşim ve işleme yönelik hizmet sunan belediyelerin az sayıda olması dikkat çekmektedir.
Uma análise ético-jurídica do tratamento dispensado às diretivas antecipadas de vontade e à eutanásia no âmbito do PLS nº 149/2018
Authors: Lourenço Daniel Braga , Alves Alex Meira
Published: April 2021

Esta pesquisa objetiva analisar qual o tratamento dispensado à eutanásia no Projeto de Lei do Senado (PLS) nº 149/2018, que regulamenta as diretivas antecipadas de vontade. Entretanto, é dada especial atenção ao testamento vital, por ser um tema que está concatenado de forma intrínseca à eutanásia. Para tanto, são discutidos inicialmente alguns conceitos essenciais, tais como os de eutanásia ativa (direta e indireta) e passiva – aí incluída a ortotanásia, não como sinônimo, mas como um subtipo. Utiliza-se pesquisa bibliográfica e documental, pautando-se, principalmente, a partir do referencial teórico proposto por Peter Singer (2018) e confrontando-o com a perspectiva de outros autores. Foi possível observar que não há razões para se distinguir juridicamente as diversas modalidades de eutanásia ativa e a ortotanásia, como faz o projeto. O PLS nº 149/2018, na verdade, apenas replica o disposto nas Resoluções nº 1.805/2006 e nº 1.995/2012, do Conselho Federal de Medicina, é genérico e não aprofunda a regulamentação das diversas formas de eutanásia. Com isso, dá-se continuidade ao modelo paternalista na relação médico-paciente, com prejuízos evidentes à autonomia e aos direitos da personalidade do paciente.
In search of the Ethos of the Brazilian Constitution
Authors: Fachin Melina Girardi , Kanayama Rodrigo Luís
Published: April 2021

Este artigo procura identificar, se existente, o Ethos da Constituição Federal do Brasil. A busca será feita em diálogo direto com a obra de Alexander Tsesis, Constitucional Ethos (2017). Nessa perspectiva, o ethos representa a máxima central do constitucionalismo, a saber: a proteção dos direitos individuais para o bem comum. Apesar de a ideia de ethos ter sido firmemente construída sob a realidade da Constituição dos Estados Unidos, esta é muito diferente da brasileira e, portanto, sua existência é incerta na Constituição do Brasil. Nesse processo de identificação, é trazida uma perspectiva histórica a partir dos textos constitucionais brasileiros, traçando-se um paralelo entre as constituições brasileiras promulgadas, para então se tratar especificamente da Constituição de 1988. Nesse sentido, muitas comparações são feitas entre as constituições brasileira e americana, conduzindo-se um paralelo com a mencionada obra do professor Alexander Tsesis. Com base em pesquisa bibliográfica, com metodologia comparada, o objetivo é explorar se o constitucionalismo brasileiro, em função de seus contextos e complexidades históricas, possui um ethos e, em caso afirmativo, compreender o quão suscetível a mudanças e ameaças ele é.
Patient characterization and predictors of aspirin desensitization response
Authors: Cheong Zuhui , Tan Cheryl Ying Lin , Lim Chuan Poh , Soong Jie Lin , Chong Chiara Jia Min , Chan Adrian Kwok Wai
Published: April 2021

Background

Hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs) may limit the use of aspirin in patients with cardiovascular diseases. Aspirin desensitization, which is a resource-intensive process, can offer such patients access to aspirin through the induction of temporary tolerance to aspirin. However, there is limited information on aspirin desensitization response in patients undergoing aspirin desensitization for cardiac indications in Asia.

Objective

To characterize patients who have undergone aspirin desensitization, evaluate their responses to the procedure, and identify risk factor(s) associated with failure of aspirin desensitization.

Methods

We conducted a retrospective review of medical records of patients who underwent aspirin desensitization in Singapore General Hospital between 1 June 2014 and 31 October 2017. Chi-square or Fisher exact test were used to analyze categorical data while independent samples t test or Wilcoxon rank-sum test were used for continuous data where appropriate. Multivariate logistic regression was used to identify predictors of aspirin desensitization failure.

Results

All 214 patients in our study had cardiovascular indications for aspirin, with angioedema being the most common type of index reaction experienced with NSAIDs (n = 104, 48.6%). One hundred sixty-five patients (77.1%) achieved successful aspirin desensitization. In the selected sample analysis of patients with true NSAID hypersensitivity (n = 163), an index reaction of angioedema to NSAIDs was found to be significantly associated with a higher risk of failing aspirin desensitization (odds ratio, 7.21; 95% confidence interval, 1.94-26.71).

Conclusion

Majority of the patients who underwent aspirin desensitization in our institution were able to achieve tolerance to aspirin. An index reaction of angioedema to NSAIDs was identified as a risk factor for aspirin desensitization failure. This information can aid in the risk stratification of patients undergoing aspirin desensitization and ensure efficient resource allocation for this procedure.
Long-run Spatial and Temporal Yield Variability Analysis of Three Major Crops Affected by Fertilizer Use and Rainfall in Ethiopia over the Past 15 Years (2004/05–2018/19)
Authors: Demiss Mulugeta , Sanabira Joaquin , Singh Upendra
Published: April 2021

Ethiopia is one of the major producers of maize and wheat and the only producer of teff at a larger scale for grain in sub-Saharan Africa (SSA). Various efforts have been made by the government of Ethiopia to increase productivity over the past 15 years. Here we analyze a dataset with more than 1,260 yield observations from 2004/05 to 2018/19 for three crops (teff, maize, and wheat) in the 28 zones of the two major cereal-growing regions of the country. These two regions, Amhara, and Oromia represent around 81% of cropped area, 75% of fertilizer use, and 82% of cereal production of Ethiopia annually. Zonal level crop production data were used to analyze spatial and temporal patterns of teff, wheat, and maize yield. Zones were categorized as wet and dry based on annual rainfall. We dissect the evolution of yield trends over time and space, analyze yield variation, and evaluate whether growth of yields has increased, decreased, or stalled in recent years. We found that productivity of teff, wheat, and maize continued to increase from 0.95 to 1.76 metric tons per hectare (mt ha -1), 1.56 to 2.76 mt ha -1, and 1.72 to 4.0 mt ha -1 respectively, between 2004/05 and 2018/19. There was an average annual increase of 5%–8% during this time. The data also show a strong correlation of yield with rainfall and fertilizer use patterns; therefore, we recommend that the fertilizer advisory service should also make use of the rainfall conditions of the different locations to fine-tune fertilizer recommendations.
Transiciones y soportes. La familia y la comunidad en las trayectorias biográficas de adolescentes trans
Authors: Parra Noemi
Published: April 2021

Este artículo forma parte de una investigación en curso sobre la experiencia biográfica de la adolescencia trans. En él exploro el papel de la familia y la comunidad como soportes en las trayectorias de transición. Comprendo la adolescencia trans como un fenómeno sociocultural que regula las concepciones de edad y género, y en el que la experiencia de transición de los sujetos se da en el contexto sociohistórico sobre el que el sujeto decide y actúa. El Método Biográfico Narrativo Interpretativo me permite mostrar el papel de la familia y la comunidad como soportes en la trayectoria biográfica de transición de adolescentes trans, a partir de los siguientes temas: contarlo a la familia; la aceptación/rechazo familiar; y, cuando la familia rechaza, la comunidad sostiene. Para finalizar, en las conclusiones rastreo de qué manera actúan los soportes en el sentido y cuidado de sí de las personas adolescentes trans.
Resiliencia y cultura terapéutica en tiempos neoliberales: una exploración de discursos de autoayuda
Authors: Martínez Guzmán Antar , Medina Cárdenas Omar
Published: April 2021

Desde las ciencias sociales, y específicamente desde áreas como la Psicología Positiva, la resiliencia se entiende como una capacidad individual para resistir y re-construirse ante condiciones adversas. Situando dicho concepto en el fenómeno de la cultura terapéutica y en manifestaciones particulares de ésta, como la literatura de autoayuda, es posible interrogar los procesos de subjetivación que construyen discursivamente al sujeto en el marco de la gubernamentalidad neoliberal. En este tra-bajo se presenta un análisis del discurso de cuatro obras de autoayuda sobre resiliencia. Con la identificación de repertorios interpretativos, se encontró que la subjetividad resiliente está atravesa-da por determinismos cognitivistas, esencialismos psicológicos y biológicos, y por una lógica econo-micista vinculada con la racionalidad neoliberal. Se concluye que estos discursos incitan a una cons-tante exposición a los riesgos como parte de una gestión de la vida que aspira a un incesante poten-ciamiento de las capacidades individuales.

This study on the interactional experience of people who have visual impairments or disabilities in using Go-jek and GrabAndroid applications employs usability testing using mixed approach. It is an explanatory sequential design research;quantitative data were measured in time, number of errors, Single Ease Question (SEQ) questionnaire score and SystemUsability Scale (SUS) score. They were used to evaluate the usability level of the application, and finger mapping dataand participant comments were used to find more specific problems in the design or look for user patterns. Usabilityevaluation was carried out on 6 sub-applications from Go-jek and Grab companies. Good grouping of visual elementsand the completion of a small task makes usability perceptions increase. Yet, the design problems that make usabilityperception decrease are touch targets that are too small in size, bad visual element grouping, too many items in one page, and unfamiliar operational gestures. This research has also found that high usability score is not always determinedby visual elements. Navigation behavior has an important role in making good usability perception in users with visualimpairment. A problematic visual design could be considered a problem in one navigation method, but not in another.
Textile Antenna for First-Person View Goggles
Authors: Andre Luis , Pinho Pedro , Gouveia Carolina , Loss Caroline
Published: April 2021

Unmanned Aerial Vehicles, also known as drones, are vehicles controlled remotely. First-Person View (FPV) technology allows these vehicles to have greater versatility and be more easily piloted. The antennas currently used for video transmission are bulky and uncomfortable, so there is a need for this volume to be reduced to increase portability, being this the focus of the paper. The antenna was developed in textile materials to reduce its size and weight, as these materials allow for a better comfort and a reduced footprint. This paper presents a microstrip array adapted for the frequencies used in FPV video transmission. The designed textile antenna was compared with a commercially available rigid antenna used for this transmission. The comparison shows promising results for the antenna made of textile materials. The main goal of increasing the comfort and portability of the FPV goggles was achieved.
The concept of power in computer-mediated communication
Authors: Hastrdlová Šárka
Published: April 2021

There has been a recent increase of interest in the phenomenon of power amongst linguists and also philosophers. The presented article attempts to consider power and ways in which it is exercised through language of computer-mediated communication (further CMC). This unique environment is determined by the specific conditions of an Internet chat room, such as anonymity and no audio-visual cues. In the theoretical part, Watts’s and Diamond’s investigations of power in various open and closed groups in oral communication are discussed and the notion of status is presented. The author divides the chat group corpus into individual sub-groups and tries to draw a graphical presentation, a sociogram, to show their complexity and distribution of power. However, the question remains how tight the sub-groups in CMC are or how interrelated they are with one another. In this respect, it is noteworthy to observe how a selected chat participant develops her status in various sub-groups and to analyze the means by which this possible status is achieved. The corpus was collected by the author herself. The main hypothesis is that the status of power changes quickly throughout chatting and it depends to a great extent on other cues such as address, non-verbal action displays, punctuation marks and so on. In other words, there are very few means by which to exercise power and hold it in this continuously changing and anonymous environment.
The Ethics of COVID-19 Vaccine Passports
Authors: Meaney Joseph ,   The National Catholic Bioethics Center
Published: April 2021

COVID-19 vaccine passports run the risk of creating a divided society where social privileges or restrictions based on “fitness” lead to discrimination based on immunization status. Individuals have a strong right to be free of coercion to take a COVID-19 vaccine, and we should be very leery of further invasion of private medical decisions. These concerns are shared both internationally and in the United States, and the World Health Organization, the Biden administration, and many US governors oppose COVID-19 vaccine credentials. In addition, regulations for COVID-19 vaccine credentials face practical barriers, including lack of access globally, especially among the poor; and lack of scientific data on the efficacy of these vaccines.
Response to Austriaco on Vaccine Passports
Authors: Meaney Joseph ,   The National Catholic Bioethics Center
Published: April 2021

This essay clarifies the author’s objections to COVID-19 vaccine credentials voiced in “The Ethics of COVID-19 Vaccine Passports.” The author’s objections centered on discriminatory practices based on vaccine status for domestic social and work activities, but he agrees with the World Health Organization that these credentials should not be required for international travel. In addition, there is a significant ethical different between currently available COVID-19 vaccines and the yellow fever vaccine because the former are produced or tested using abortion-derived cell lines. The yellow fever vaccine is much less ethically problematic. This situation could change with the approval of new COVID-19 vaccines without links to abortion-derived cell lines.
The COVID-19 Pandemic qua Artefact

In this article I argue that the COVID-19 pandemic is an unintended artefact with emergent features. Not only is the pandemic an accidental consequence of human agency, it also a) emerges from but is not reducible to its basal features, and b) possesses the features of radical novelty, coherence, wholeness, dynamism, ostensiveness, and downwards causation.
The impact of the crisis caused by coronavirus on business decisions of the companies whose shares are listed on the Banja Luka stock exchange: Example of the dividend payment decision
Authors: Radivojac Goran , Mekinjić Boško , Krčmar Aleksandra
Published: April 2021

The subject of this paper is an analysis of the impact of the crisis caused by coronavirus on business decisions of issuers whose shares are listed on the Banja Luka Stock Exchange, through the example of dividend payment decisions. For the purpose of determining the factual situation, we observed publicly available financial reports of all companies that paid dividends from profits for 2018 and 2019 and made a comparison of profit retention rates in the two observed periods. We also analyzed other available information on the operations of these issuers. The research results show that in 10 out of 16 cases in which there was dividend payment from profits for 2019, the rate of profit retention increased compared to 2018. In addition to the mentioned 16 cases of dividend payment from the profit for the previous year, two cases were recorded in which dividend payment was made, but from the accumulated profit of previous years, so that the retention rate was not calculated for these issuers. If we take into account the fact that, in almost all cases, the decision on the (non-)payment of dividends was made at a time when uncertainties regarding coronavirus were already present in Republika Srpska, it can be concluded that the impending crisis had an impact on 2019 net results distribution decisions.

Published: April 2021

This paper investigates the joint impact of interest rate and exchange rate volatility on the performance of the informal sector in Nigeria, focusing on Small and Medium-sized Enterprises (SMEs). The annual time-series data on the exchange and interest rates for the period 1981-2018 were obtained from where exchange and interest rates volatility data were computed. The data analysis was carried out using descriptive statistics, correlation, a unit root test, an Autoregressive Distributed Lag (ARDL) bound test for cointegration and the ARCH regression model. The results obtained by the ARDL bound test confirmed the presence of the long-term relationship between interest and exchange rates volatility and SMEs' performance, which suggests that all the variables of interest move together in the long run. Moreover, the ARCH regression model showed a positive impact of exchange and interest rates volatility on SMEs' performance. However, only exchange rate volatility was significant. Thus, policy makers should pursue the interest rate and exchange rate regimes that will encourage massive investments in SMEs. This, in turn, would increase the performance of SMEs. Also, the monetary authorities should implement the policies aimed at curtailing incessant volatility in the exchange rate and the interest rate so as to protect SMEs from the external perturbations of the movements of the exchange rate and the interest rate.
The development of mechanics and engineering design and machine theory since the rennaissance
Authors: Chondros Thomas
Published: April 2021

The history of science and mechanics is confronted by two interconnected problems: a critical accumulation and systematization of historical information about the subject of study, and the relationship between events and the laws of their development.The influence of natural philosophy in classical times that led to the development of mechanics and engineering as a science from the 5th century B.C. to the Middle-Ages was investigated in a previous article by the author. The rapid development of mechanics as a science started in the 16th and the 17th century. Machine design as an applied science was heavily relying on mechanics. Since the beginning of the 19th century, mechanics became the theoretical basis of an increasing number of applied technical disciplines directly connected with the development of industry, the elaboration of new technological processes machines, and industrial plants. A brief history of the development of the theory of machines and mechanisms is attempted here, along with the personalities and Academic Institutions that influenced Mechanisms and Machine Theory from Medieval Times to the recent past.

The upper bound power method is used to simulate the process of combined radial-backward-forward extrusion of hollow parts of the "cup with flange and branch pieces" type from a continuous workpiece. The calculation scheme with autonomous deformation zones is used, which contains modules with an inclined boundary and the condition for the equality of powers acting on both sides of the intermediate hard zone is accepted. This made it possible to more accurately determine the power regime and the prevailing direction of the metal flow, which is necessary to assess the character of the forming of the part. The comparison of theoretical and experimental values of the deformation pressures and the flow velocities with each other, as well as with the results obtained by the finite element method shows the feasibility of using the obtained functions for technological calculations of power parameters and evaluating of part forming.

Published: April 2021

The results of microstructure effect on corrosion-mechanical endurance of 1.2 mm thick alloy of Al-Mg-Si-Cu alloying system and its welded joints, depending on their condition due to different types of HT are presented. Change of microstructure of the welded joints during performance of various HT operations practically does not affect its resistance against intergranular and exfoliating corrosion. Effect of HT on corrosion-mechanical endurance of welded joint under the conditions of simultaneous action of continuous loading and corrosive environment is ambiguous. Resistance against intergranular corrosion and corrosion cracking will determine the fracture resistance of welded products of V1341T alloy in service.

Soil preparation with single-operation serial machine-tractor units requires multiple passes over the field, which leads to excessive soil compaction and loss of fertile layer, increased consumption of fuel and lubricants. The use of machines with dynamic tillage tools to prepare the soil for sowing allows regulation of soil pulverization intensity and performing a technological operation in one pass. The aim of the research is to study the possibilities of a combined approach to graded tillage, combining static and dynamic tillage tools. The main disadvantages of tiller are poor penetration ability, high metal and energy consumption. The authors found that the rational joint use of static and dynamic tillage tool in the cultivator for graded soil treatment may reduce the energy consumption for the top layer cultivating by 1.5 times. Such aspects, as the degree of influence of the parameters and operating modes of the tiller on the specific energy consumption of processing, soil pulverization intensity and degree of the content of erosion-hazardous particles in the upper layer are revealed, design and operating parameters of the combined cultivator and its tillage tools are substantiated.
Shiʻa mystical theology: Notes on Sayyid Ḥaydar ĀmulĪ's 'Jāmiʻ al-Asrār wa Manbaʻ al-Anwār'
Authors: Amir Hossein
Published: April 2021

There is a certain tendency among the scholars of Shī'ī Islam to synthesize Shī'īsm and Sufism within the Islamic context. Chief among these scholars is Bahā' al-Dīn Ḥaydar b. 'Alī b. Ḥaydar al-'Ubaydī Āmulī (1319 or 1320 - after 1385) known as Ḥaydar-i Āmulī whose Jāmi' al-Asrār wa Manba' al-Anwār is one of his essential works in which the interrelation between Shī'īsm and Sufism developed. This paper tries to look closely at the Jāmi' al-Asrār to depict the ways and approach in which Āmulī necessitates the identicality of the Shī'ī-Sufi approach. In the same framework, his relation to Ibn Arabi is examined. Āmulī's approach is called a marginalized one by some in the Shī'ī seminary. This paper, on the other hand, indicates that Āmulī's approach is more a continues and existing movement rather than a marginalized historical approach.

The emergence of labor absenteeism is extremely complex, which is supported by the fact that from today's perspective, it has resulted in a large number of organizational phenomena that are studied in detail. The sociological aspect of absenteeism as a primarily social phenomenon needs to be analyzed from the social aspect so it is studied through sociological, psychological and socio-economic factors, demographic characteristics, work socialization and health status, interacting with the working environment and the environment, which are interconnected and mutually conditioned. Numerous factors influencing work absenteeism can be grouped and defined as characteristics of work and work situation, individual characteristics and characteristics of out of work situation. Knowledge, monitoring and understanding of these factors, i.e. those organizational moments that are recognized as social causes of the emergence and development of absenteeism in the organization is of immeasurable importance, which is the focus of this paper.

The trial in this study was carried out in field conditions throughout three years from plots where seed production of sunflower parental lines was established. Eight genotypes were examined; namely RHA-UK, RHA-ST-59, RHA-SES-IMI, RHA-SNRF, RHA-E-ANN-65, RHA-RU-3, RHA-CDN, and RHA-N-M-1. All the examined genotypes are parental components of the best sunflower hybrids developed by the Institute of Field and Vegetable Crops, Novi Sad, Serbia. Relationships between seed yield and eight different traits in sunflower were studied - oil and protein content, seed germination, 1000-seed weight, head diameter, number of branches and leaves and plant height. The same analyses were carried out for comparison of oil content. A highly significant positive correlation was determined between plant height and number of branches; plant height and the number of leaves; plant height and head diameter; plant height and seed yield; number of branches and yield; the number of leaves and yield; head diameter and seed yield; number of leaves and number of branches; number of leaves and head diameter and between seed germination and oil content. Path analysis indicated highest significant direct effect of plant height on yield (0.439**). The number of branches had a significant positive direct effect on yield (0.260*). In the study of indirect effects on yield, thirteen significant effects were determined. The study of direct effects on oil content showed that the plant height and number of leaves diameter had high significant effects (0.800** and -0.847**). The existence of indirect significant effects on oil content was determined in nine cases.

Published: April 2021

This study examined tourists' perception of ecotourism services in Lagos, Nigeria, with the specificity of the Lekki Conservation Centre. Specific objectives were to identify the elements of tourists' demand concerning destination loyalty in the study area. A total of 300 domestic and inbound tourists were sampled, over ten months, using a structured questionnaire. Descriptive statistics were used for data analysis. The findings revealed the availability of vital tourism-related products to meet tourist demand, a conducive tourism atmosphere, and a dispersed location of the species in the conservation center with the availability of quality tourism facilities. However, tourists' perception and experience were poor compared to available infrastructural components. The study concludes that managers of the centre have not employed quality destination management and marketing techniques to improve their image and enhance inbound tourism. Recommendations included the need for the provision of more facilities and species, and an improved means of transportation to enhance tourist accessibility to the centre.

Published: April 2021

Ensino remoto, aula assíncrona e plataforma de comunicação são termos, entre outros, que entram no vocabulário do cotidiano das pessoas desde que a pandemia de Covid-19 nos forçou ao isolamento social em março de 2020. Esse fato tornou relevante a discussão sobre os ecossistemas de comunicação possibilitados pela importância das mídias em nosso cotidiano, seja no trabalho, nas relações familiares e nas escolas. Com a pandemia de Covid-19, as mídias adquiriam um papel ainda mais relevante no nosso cotidiano e sua inserção na prática escolar deixa de ser a discussão da ordem do dia para ser o processo comunicacional que cada uma viabiliza. Neste artigo, identificamos como a comunicação é feita nos Modos Estrela, Círculo e Rede e qual ecossistema de comunicação corresponde a cada um e discutimos como o conceito de ecossistema torna-se interessante para compreender os processos comunicacionais e educacionais. Propomos, por fim, o esquema de um ecossistema educomunicativo como uma ferramenta para, a partir do aprendido durante a pandemia, elaborar propostas para a pós-pandemia.
