Online learning, also known as e-learning, is the result of the evolution of distance learning that has developed following technological developments, especially information technology. Before the pandemic, online learning was only one alternative that enriched the learning process. Various courses are implemented by combining offline and online learning processes called blended learning. Through the Learning Management System (LMS), the Department of Architecture Unhas combines offline and online learning in studio-based design courses. Lecturers and students are trained to carry out the stages of the learning process guided by online procedures. The ongoing Covid-19 pandemic has made online learning the only way to keep the learning process going as planned. The sudden shift of studio-based courses from offline to totally online resulted in a change in the learning environment and experience. This study found that the online learning process is largely determined by the availability of learning materials and instruction in the LMS, the distance between learning space and time, the learning experience and the meaning of independent learning perceived by students. The study involved student participants at all semester levels, academic administration staff, lecturers, and student parents.

The impact of the COVID-19 pandemic has prompted the government to carry out social assistance programs. The purpose of this study is to analyze Universal Basic Income as a response to the COVID-19 pandemic which can simultaneously strengthen economic defenses in Indonesia as a form of peace dividends. This research uses the literature study method to previous relevant research strategy theory by identifying ends, ways, and means. The results of this study support universal basic income as a policy (ways) to deal with the crisis due to COVID-19 pandemic. UBI can provide an increase in Indonesia’s economic growth and empower Indonesian people to be better prepared to face risks, which will lead people to innovate more. UBI can also strengthen the defense economy in Indonesia because by reducing poverty, unemployment and social inequality, the crime rate caused by the economy will decrease, human resources will increase, and community relations will be stronger (ends). The resources (Means) needed to implement UBI in Indonesia are the budget, existing regulations, human resources (HR), and the latest Indonesia’s population data.

We estimate the willingness to taking the booster dose in a representative sample of Danes. We estimate an overall willingness in the adult Danish population of 85.5 percent and a willingness of 94.7 percent among primary vaccine takers. We, moreover, show that these percentages will be significantly lower among younger populations as well as among groups who do not see COVID-19 as a threat towards society and who do not perceive the advice of the health authorities as effective against disease spread.

Faced with the SARS-CoV-2pandemic, we decided to investigate if recovery from this large exogenous global shock depended on both emotional and economic recovery. We piloted a survey from May 2020 – August 2020 to examine how exposure to this global pandemic shaped economic outlook, and we documented the innate emotional styles of respondents. We then sought to answer two questions. Do the emotional style dimensions have anything to do with economic recovery? And are wages and emotional dimensions associated with economic outlook? With these questions in mind, we estimated two structural equation models. We jointly estimated all six emotional dimensions for the first question and assessed their impact on economic outlook. We estimated a structural model with a Mincer-wage equation and emotional outlook, resilience, and attention equations for the second question. We found that emotional outlook was positively and significantly correlated with economic outlook. We also found that wages, emotional- outlook, resilience, and attention were correlated with returning to behavior-normal, meaning once the public health crisis abates, fear will cease to restrict mobility in all sectors. We found pessimism over returning to business-normal, patronizing businesses that are significantly affected by the pandemic could have a dampening effect on economic recovery. However, this could be offset by the positive correlations between emotional outlook on economic outlook and returning to behavior-normal, both of which could boost economic recovery. From a public policy standpoint fostering a positive emotional outlook and encouraging emotional resilience could be the mojo needed for faster economic recovery.

<li><strong>‘Variant fatigue’? Public attitudes to COVID-19 18 months into the pandemic: A qualitative study</strong> -

<div>

Objectives: Qualitative study exploring public attitudes to COVID-19 18 months into the pandemic, specifically focused on adherence to infection-reducing behaviours and policy measures during a period of the emergence of a new variant (Omicron) Study design: Qualitative online focus group study Methods: Focus groups were conducted with a diverse sample of 22 adults in the United Kingdom to explore their views. Data were analysed using a framework approach. Findings: Analysis revealed two main groups based on participants’ perceived concern over Omicron: variant fatigue (n=16 (73%)) and deja vu (n=6 (27%)). Those exhibiting variant fatigue reported not adopting any additional caution or infection-reducing behaviours as a result of the new variant. They tended to describe Omicron as ‘just another variant’ and expressed a need to ‘get on’ and ‘live with’ the virus. Those exhibiting deja vu suggested that Omicron was of additional concern to them and for some posed a threat not seen since ‘last year’ (second wave). No demographic patterns emerged, although there was a high amount of variant fatigue (absence of additional caution) (n=5 (83%)) amongst the unvaccinated participants. Those who were concerned about Omicron tended to report reducing social contacts. Few participants reported taking lateral flow tests regularly, except for those required to by their employers. Stated compliance with facemask rules was high. Nearly all participants stated an intention to comply with any future potential policy measures to reduce transmission of COVID-19, including more stringent measures such as lockdowns. Implications: 18 months into the pandemic, there may be habituation to the risk posed by COVID-19, despite the increased risk posed by the new variant Omicron. Due to this risk habituation (‘variant fatigue’) and due to a general decline in engagement with news related to COVID-19, many people may not be, or might be reluctant to, voluntarily adopt additional caution and infection-reducing behaviours. This poses a challenge for public health communication, since a sense of being ‘relaxed’ about, or ‘living with’ COVID-19 may undermine efforts to encourage voluntary adherence to infection-reducing behaviours. However, findings suggest that most people intend to comply (albeit reluctantly) with policy measures (as opposed to ‘advice’)- including stringent measures such as lockdown - if they were required in future.

<li><strong>Agreeableness and neuroticism predict being more concerned about COVID-19 and bothered by friends’ risky behavior</strong> -

Given the importance of friendships during challenging times and the mixed associations reported between personality traits and disease-related behaviors, we investigated the influence of personality traits on friendships during the COVID-19 pandemic and how both influenced risky behaviors. In November 2020, we asked participants about their reactions to friends’ behavior as part of a larger study. We found that agreeableness and neuroticism predicted participants being more concerned about COVID-19 and bothered by friends’ risky behavior, and extraversion predicted enjoying helping friends during the pandemic. Our results suggest that personality influences how individuals cope with their friends’ risky behaviors. This work could be relevant for developing interventions to reduce risk taking during the pandemic, such as using friendships to reinforce adherence to public health guidelines.

To address the global Covid-19 pandemic, governments around the world require on the collective cooperation of their citizens to comply with public health regulation. Earlier studies examined the extent to which self-construal has an impact on individual compliance to law. However, existing literature has paid little significant attention to behavioural outcome of self-construal in the pandemic context across countries and cultures.

<li>to determine whether interdependent self-construal predicts compliance of Covid-19 public health regulation, 2) to examine if the association was mediated by individual social trust, and 3) to test whether these associations were moderated by respondent’s country of residence (US x Indonesia). General adult respondents from US (N=231) and Indonesia (N=440) were voluntary participated in a survey measuring their trust to the government, interdependent self-construal orientation and compliance toward Covid-19 public health regulation. While our moderated mediation model involving respondent’s country residence did not support the hypothesis, the mediation analysis demonstrated significant association between interdependent self-construal and compliance via social trust. Our additional simple moderation analysis on direct effect of interdependent self-construal and compliance showed significant findings. Further, theoretical and practical implications of these findings were discussed in the following paper.

The COVID-19 Pandemic has had a significant impact on society. Due to the large lose of life, scientists have attempted to develop various rapid testing methods. Several methods have been developed among them, an inexpensive paper test. The researcher has endeavored to determine what factors will influence a person’s willing to take a daily covid-19 test. Via a survey instrument that was disseminated we received a response of N=546 participants. We performed many standard statistical tests, t-tests, and one way ANOVA’s as well as Chi Squared tests and Linear by linear associations. Via this analysis were able to determine that there is a statistical significance between willingness to take daily rapid covid-19 test (p <0.05 and, washing your hand (p <0.001), being cautious of your actions (p <0.001), being concerned about covid-19 (p <0.001) and preventing things before they happen (p <0.001). Risk averse people more likely to take preventative measures to take actions to protect themselves and others around them. The lack of basic knowledge regarding the replication of SAR-CoV-2, has led people to underestimate the rapid spread of the virus. Thus, people are coming in contact with others during the most virulent state of the virus.

Abstract Backgroud: Since 2021, all outbreaks of COVID-19 within mainland China have been associated with imported cases from abroad. The outbreak in Putian, Fujian province, occurred without obvious loopholes in the implementation of epidemic prevention, indicating loopholes in the current epidemic prevention strategies in mainland China. The loopholes should be identified and the epidemic prevention strategies should be improved as soon as possible. Methods: Is there a need to further extend the medical observation period and community health surveillance period for key populations? Is there a need to increase the number of nucleic acid screenings? Is there a need to change the methods of extraction of nucleic acid screening samples? Is there a need to expand the scope of the population for routine epidemic prevention surveillance? The analysis of these questions would contribute to the improvement of the COVID-19 epidemic prevention strategies. Results: There are larger outbreaks following the current intensive isolation medical observation period and community health surveillance period, the phenomenon shows that the loopholes in the assessment of cross-infection risk and health surveillance in China’s current COVID-19 prevention and control strategies, especially during health surveillance after the entry of undetected infected individuals into the community when they emerge during isolation medical observation, and during health surveillance in the community for those who regain positive status after case cure. Conclusions: The key points to improve epidemic prevention strategies includ that a scientific and rational assessment around the mean incubation period, cross-infection risk, and surveillance efficiency of COVID-19, and updating routine epidemic prevention surveillance measures for key populations, recently cured patients of COVID-19, and immersion populations. Keywords: COVID-19, epidemic prevention strategy, incubation period, cross-infection

Background: The COVID-19 pandemic might affect mental health. Data from population-representative panel surveys with multiple waves including pre-COVID data investigating risk and protective factors are still rare. Methods: In a stratified random sample of the German household population (n=6,684), we conducted survey-weighted multiple linear regressions to determine the association of various psychological risk and protective factors with changes in psychological distress (PD; measured via PHQ-4) from pre-pandemic (average of 2016 and 2019) to peri-pandemic (both 2020 and 2021) time points. Control analyses on PD change between two pre-pandemic time points (2016 and 2019) were conducted. Regularized regressions were computed to inform on which factors were statistically most influential in the multicollinear setting. Results: PHQ-4 in 2020 (M=2.45) and 2021 (M=2.21) was elevated compared to 2019 (M=1.79). Several risk factors (catastrophizing, neuroticism, asking for instrumental support) and protective factors (perceived stress recovery, positive reappraisal, optimism) were identified for the peri-pandemic outcomes. Control analyses revealed that in pre-pandemic times, neuroticism and optimism were predominantly related to PD changes. Regularized regression mostly confirmed the results and highlighted perceived stress recovery as most consistent influential protective factor across peri-pandemic outcomes. Conclusions: We identified several psychological risk and protective factors related to PD outcomes during the COVID-19 pandemic. Comparison to pre-pandemic data stress the relevance of longitudinal assessments to potentially reconcile contradictory findings. Implications and suggestions for targeted prevention and intervention programs during highly stressful times such as pandemics are discussed.

<div>
|

|
|
The COVID-19 pandemic is an exemplar of how scholarly communication can change in response to external shocks, even as the scholarly knowledge ecosystem is evolving rapidly, and many argue that swift and fundamental interventions are needed. However, it is much easier to identify ongoing changes and emerging interventions than to understand their immediate and long term impacts. This is illustrated by comparing the approaches applied by the scientific community to understand public health risks and interventions with those applied by the scholarly communications community to the science of COVID-19. There are substantial disagreements over the short- and long- term benefits of most proposed approaches to changing the practice of science communication, and the lack of systematic, empirically-based research in this area makes these controversies difficult to resolve. We argue that the methodology of analysis and intervention developed within public health can be usefully applied to the science-of-science. Starting with the history of DDT application, we illustrate four ways complex human systems threaten reliable predictions and blunt ad-hoc interventions. We then show how these four threats apply lead to the last major intervention in scholarly publication – the article publishing charge based open access model – to yield surprising results. Finally, we outline how these four threats may affect the impact of preprint initiatives, and we identify approaches drawn from public health to mitigate these threats.

A damaging inflammatory response is strongly implicated in the pathogenesis of severe COVID-19 but mechanisms contributing to this response are unclear. In two prospective cohorts, early non-neutralizing, afucosylated, anti-SARS- CoV-2 IgG predicted progression from mild, to more severe COVID-19. In contrast to the antibody structures that predicted disease progression, antibodies that were elicited by mRNA SARS-CoV-2 vaccines were low in Fc afucosylation and enriched in sialylation, both modifications that reduce the inflammatory potential of IgG. To study the biology afucosylated IgG immune complexes, we developed an in vivo model which revealed that human IgG-Fc{gamma}R interactions can regulate inflammation in the lung. Afucosylated IgG immune complexes induced inflammatory cytokine production and robust infiltration of the lung by immune cells. By contrast, vaccine elicited IgG did not promote an inflammatory lung response. Here, we show that IgG-Fc{gamma}R interactions can regulate inflammation in the lung and define distinct lung activities associated with the IgG that predict severe COVID-19 and protection against SARS-CoV-2.

<div>

The mutational landscape of SARS-CoV-2 varies at both the dominant viral genome sequence and minor genomic variant population. An early change associated with transmissibility was the D614G substitution in the spike protein. This appeared to be accompanied by a P323L substitution in the viral polymerase (NSP12), but this latter change was not under strong selective pressure. Investigation of P323L/D614G changes in the human population showed rapid emergence during the containment phase and early surge phase of wave 1 in the UK. This rapid substitution was from minor genomic variants to become part of the dominant viral genome sequence. A rapid emergence of 323L but not 614G was observed in a non- human primate model of COVID-19 using a starting virus with P323 and D614 in the dominant genome sequence and 323L and 614G in the minor variant population. In cell culture, a recombinant virus with 323L in NSP12 had a larger plaque size than the same recombinant virus with P323. These data suggest that it may be possible to predict the emergence of a new variant based on tracking the distribution and frequency of minor variant genomes at a population level, rather than just focusing on providing information on the dominant viral genome sequence e.g., consensus level reporting. The ability to predict an emerging variant of SARS-CoV-2 in the global landscape may aid in the evaluation of medical countermeasures and non-pharmaceutical interventions.

Designated a pandemic in March 2020, the spread of severe acute respiratory syndrome virus 2 (SARS-CoV2), the virus responsible for coronavirus disease 2019 (COVID-19), led to new guidelines and restrictions being implemented for individuals, businesses, and societies in efforts to limit the impacts of COVID-19 on personal health and healthcare systems. Here we report the impacts of the COVID-19 pandemic on pancreas processing and islet isolation/distribution outcomes at the Alberta Diabetes Institute IsletCore, a facility specialising in the processing and distribution of human pancreatic islets for research. While the number of organs processed was significantly reduced, organ quality and the function of cellular outputs were minimally impacted during the pandemic when compared to an equivalent period immediately prior. Despite the maintained quality of isolated islets, recipient groups reported poorer feedback regarding the samples. Our findings suggest this is likely due to disrupted distribution which led to increased transit times to recipient labs, particularly those overseas. Thus, to improve overall outcomes in a climate of limited research islet supply, prioritization of tissue recipients based on likely tissue transit times may be needed.

Household savings account for more than half of a country’s capital formation, which fluctuates due to a variety of economic factors such as inflation and interest rates. Households should gradually shift their savings and investments from physical assets to financial assets to avoid a sudden change in wealth. They should also save and invest using a variety of platforms. Trends in investing and saving will be easier to track and measure this way. This year’s domestic saving rate in India is 2.3 percent lower than last year’s and 1.2 percent lower than the year before. Since 2011, general domestic savings have been steadily declining, with the trend continuing into the following year. According to official data, the GDP in 2020 shrank by 23.9%, the least in previous years and the least since the Covid-19 pandemic in previous years. As a result, the information presented in this paper is drawn from and evaluated from other sources - <a href="https://patentscope.wipo.int/search/en/detail.jsf?docId=IN340502149">link</a></p></li>
