Title A name given to the resource Analyses of Commercially Available Alcohol-Based Hand Rubs Formulated with Compliant and Non-Compliant Ethanol Creator An entity primarily responsible for making the resource Fina B. Nelson, Timothy J. Tse, Martin J. T. Reaney Description An account of the resource The COVID-19 pandemic led to panic-buying of alcohol-based hand rubs (ABHRs). In response, governmental agencies (e.g., Health Canada) permitted the sale of ABHRs formulated with “technical-grade” ethanol to alleviate the growing demand. Technical-grade ethanol contains elevated concentrations of impurities (e.g., acetaldehyde, etc.), which may exhibit dose-dependent toxicity. In this study, a rapid solvent extraction was employed to analyze gelled ABHRs via gas chromatography with flame ionization detection. In total, 26 liquid and 16 gelled ABHRs were analyzed for nine common impurities to determine compliance with Health Canada interim guidelines. Of 42 samples analyzed, 11 ABHRs appear to be non-compliant with interim Health Canada guidelines. Non-compliant ABHRs exhibited elevated concentrations of acetaldehyde, with a maximal concentration observed of 251 ± 10 µL L−1; 3.3× higher than currently permitted. Nonetheless, frequent testing of ABHRs should be routinely conducted to reduce the risk of consumer exposure to non-compliant ABHRs.

Title A name given to the resource Analyses of spike protein from first deposited sequences of SARS-CoV2 from West Bengal, India [version 1; peer review: 2 approved, 1 approved with reservations] Creator An entity primarily responsible for making the resource Prem Prakash Tripathi, Upasana Ray, Feroza Begum, Debica Mukherjee, Sandeepan Das, Arup Kumar Banerjee, Dluya Thagriki Description An account of the resource India has recently started sequencing SARS-CoV2 genome from clinical isolates. Currently only few sequences are available from three states in India. Kerala was the first state to deposit complete sequence from two isolates followed by one from Gujarat. On April 27, 2020, the first five sequences from the state of West Bengal (Eastern India) were deposited on GISAID, a global initiative for sharing avian flu data. In this study, we have analysed the spike protein sequences from all five isolates and also compared their similarities or differences with other sequences reported in India and with isolates of Wuhan origin. We report one unique mutation at position 723 and another at 1124 in the S2 domain of spike protein of the isolates from West Bengal only.  There was one mutation downstream of the receptor binding domain at position 614 in S1 domain which was common with the sequence from Gujarat (a state of western India).  Mutation in the S2 domain showed changes in the secondary structure of the spike protein at region of the mutation. We also studied molecular dynamics using normal mode analyses and found that this mutation decreases the flexibility of S2 domain.  Since both S1 and S2 are important in receptor binding followed by entry in the host cells, such mutations may define the affinity or avidity of receptor binding.

Title A name given to the resource Analysing and Comparing Warrantless Tax Inspections and Searches Creator An entity primarily responsible for making the resource Fareed Moosa Description An account of the resource Sections 45 and 63 of the Tax Administration Act 28 of 2011 (TAA) confer drastic information gathering powers on officials of the South African Revenue Service (SARS). On the one hand, section 45 permits warrantless routine (non-targeted) and non-routine (targeted) inspections by a SARS official in respect of records, books of accounts and documents found at premises where a taxpayer is reasonably believed to be conducting a trade or enterprise. The purpose of such inspection is to determine whether there has been compliance with specific obligations by the taxpayer. Section 63, on the other hand, permits, on the grounds of urgency and expediency in exceptional circumstances only, warrantless non-routine (targeted) searches by a senior SARS official of a taxpayer and of third parties associated with a taxpayer, as well as searches of a taxpayer's premises and those of third parties. In addition, section 63 permits the seizure of relevant material found at premises searched. All searches and seizures must occur for the purposes of the efficient and effective administration of tax Acts generally. A comparative analysis of sections 45 and 63 of the TAA reveals the existence of key differences in the substance and practical operation of their provisions. This article distils these differences through an in-depth discussion of the nature and extent of the powers of inspection and search conferred by these provisions, as well as by conceptualising the terms “inspection” and “search” for the purposes of sections 45 and 63 respectively.

Title A name given to the resource Analysing Students’ Reasons for Keeping Their Webcams on or off during Online Classes Creator An entity primarily responsible for making the resource Vasile Gherheș, Simona Șimon, Iulia Para Description An account of the resource Since, in some higher education institutions, it is not mandatory for students to turn their webcams on during online classes, teachers have complained that their students have adopted this behaviour once the educational activities moved online due to the COVID-19 pandemic. Considering this, the present research aimed to identify the reasons behind students’ choice to hide their faces during online classes and find possible solutions to remedy the situation to enhance the educational process’s sustainability. Thus, this article presents the results obtained by applying an online questionnaire between December 2020 and January 2021 among the students pursuing an academic degree, recording 407 responses. The results highlighted the fact that more than half of the students participating in the study reported that they do not agree to keep their webcams on during online classes, the main reasons being anxiety/fear of being exposed/shame/shyness, desire to ensure privacy of the home/personal space, and chances that other people might walk into the background. The relevance of the research, besides the scarcity of studies on the topic, is also given by the fact that finding and understanding the reasons for this behaviour are, in fact, the first steps in undertaking regulatory interventions on it.

The adoption of strong and severe measures to contain the spreading of Coronavirus during March-April 2020 generated a significant reduction in private vehicle trips in the city of Rome (-64.6% during the lockdown). Traffic volumes, obtained through a simulation approach, were used as input parameters for a noise emission assessment conducted using the CNOSSOS-EU method, and an overall noise emissions reduction on the entire road network was found, even if its extent varied between road types.

Title A name given to the resource Analysis of Adaptation of Students Studying under the Flipped Classroom Model to the Conditions of Distance Learning Creator An entity primarily responsible for making the resource G. R. Chaynikova Description An account of the resource Purpose of study. In the situation of the coronavirus pandemic, distance learning technologies have become the only way to organize the educational process. The transition to distance learning required both adaptation of the content, tools and methods of teaching to the new conditions, and adaptation on the part of students, in particular, it demanded from them to be much more independent and responsible, as well as the ability to effectively use their time. In this connection, the aim of the study was to analyze how the technology of blended learning allows students to better adapt to the conditions of distance learning.Materials and methods. The author considered the following as the main indicators of students’ adaptation to distance learning: 1) actual results of learning activities; 2) the degree of students’ satisfaction with the results of their learning activity; 3) self-assessment of readiness to use ICT tools in learning process, development of independent work and self-organization skills, self-report on the psychological state. The analysis of pedagogical literature on blended learning made it possible to identify a number of important principles which the learning process should be based on in the flipped classroom model, the analysis of which, in turn, showed that they fully correspond with the principles of distance learning. All this suggests that blended learning as a component of full-time instruction, implemented from the first term when teaching English as an academic discipline, should help students better adapt to the conditions of distance learning. To confirm this hypothesis, an analysis and comparison of the results of learning activities in the conditions of blended and distance learning, as well as a questionnaire of students were conducted.Results. Comparison of the current and final performance in English as an academic subject in the conditions of blended and distance learning did not reveal any significant changes. Survey analysis showed that the transition to distance learning was a challenge for most students and demanded from them to make significant efforts  to adapt, which was manifested in a decreased level of satisfaction with the results of their learning activities in general, an increased level of anxiety, as well as highlighting a number of difficulties that they had to face. However, a comparison of data obtained on the discipline “English language”, where training was initially built on the flipped classroom model, and data on distance learning in general allows the author to conclude that the technology of blended learning makes it possible to reduce a number of difficulties, in particular, technical difficulties when switching to distance learning, and the indicator of satisfaction with the results of their learning activities shows that the flipped classroom model allows students to more fully realize their abilities and achieve the desired results not only in the conditions of blended learning, but also when switching to distance one.Conclusion. The analysis made it possible to show a significant potential of blended learning in the conditions of introducing information technologies in education. At the same time, it is necessary to keep in mind the importance of pedagogical support in the context of e-learning.
