In 2020 when schooling was abruptly reconfigured by the pandemic, young people were required to demonstrate new capabilities to manage their learning and their wellbeing. This paper reports on the feelings, thoughts and experiences of eight Year 9 and 10 students in NSW and Victoria about the initial period of online learning in Australian schools that resulted from the Covid-19 pandemic. Beyond dominant narratives of vulnerability and losses in learning, our participants offered counternarratives that stressed their capacities to rise and meet the times. We trace three central themes on how they found moments of agency that increased their confidence, reconfigured resilience as a socially responsible set of practices, deployed sociality as a resource for the benefit of themselves and others. The pandemic opened up conversations with young people about where and how learning takes place and how schools might adapt and respond to young people's growing sense of urgency about the future of schooling.International students in the secondary school sector are a particularly vulnerable group due to their age and status as unaccompanied minors. The establishment of friendships is an important component of the adjustment for these students as they transition into their new school environments. This paper presents issues related to friendships, investigated as part of a larger study examining the motivations, expectations and experiences of international students from the People's Republic of China studying in Australian secondary schools. Data were collected in two phases from 116 international students and 10 teachers using questionnaires and semi-structured interviews, and descriptive analyses employed. Because there is a paucity of information about the experiences of international secondary school students, this was an exploratory study that has contributed understanding of the lived experiences of a small group of international students from mainland China. The study identified that expectations regarding the establishment of friendships are not being met, and that international students from China are seeking more opportunities to form relationships with Australian peers. To reduce dissonance between expectations and experiences of studying in Australia, it is recommended that Australian schools work with both international and domestic students to provide authentic opportunities to build peer relationships.Driven by an unexpected transition into virtual working worldwide as a result of the Coronavirus disease 2019 (Covid-19) pandemic, in this paper, we examine the extent to which existing knowledge from the literature on virtual teams (VTs) spanning two decades can be used to inform how leadership can be exercised in the Covid-19 'new normal', involving 'reconfigured' VTs which have both similarities with, and differences from, earlier VTs. Drawing on existing literature on VTs pre-Covid-19, we explore what current (and future) VTs might look like and what this means for leadership in this new context with an emphasis on how leadership, or e-leadership, can be exercised to help the leaders of traditional, physically collocated teams that had to transition into VTs. These new e-leaders need to come to grips with a variety of new challenges in order to create high-performing and sustainable VTs. Following a semi-systematic, state-of-the-art literature review, we (a) identify key themes and explain with a theoretical model how existing knowledge can lead to new insights for newly transitioned e-leaders; (b) discuss what future information systems (IS) researchers should focus on given the reconfiguration and new characteristics of VTs in the Covid-19 context; and (c) 'translate' the findings of our synthesis of the existing literature into prescriptive advice that can be used to inform practitioners.In recent years we have witnessed a growing interest in the analysis of social media data under different perspectives, since these online platforms have become the preferred tool for generating and sharing content across different users organized into virtual communities, based on their common interests, needs, and perceptions. In the current study, by considering a collection of social textual contents related to COVID-19 gathered on the Twitter microblogging platform in the period between August and December 2020, we aimed at evaluating the possible effects of some critical factors related to the pandemic on the mental well-being of the population. In particular, we aimed at investigating potential lexicon identifiers of vulnerability to psychological distress in digital social interactions with respect to distinct COVID-related scenarios, which could be "at risk" from a psychological discomfort point of view. Such scenarios have been associated with peculiar topics discussed on Twitter. https://www.selleckchem.com/products/mcc950-sodium-salt.html For this purpose, two approaches based on a "top-down" and a "bottom-up" strategy were adopted. In the top-down approach, three potential scenarios were initially selected by medical experts, and associated with topics extracted from the Twitter dataset in a hybrid unsupervised-supervised way. On the other hand, in the bottom-up approach, three topics were extracted in a totally unsupervised way capitalizing on a Twitter dataset filtered according to the presence of keywords related to vulnerability to psychological distress, and associated with at-risk scenarios. The identification of such scenarios with both approaches made it possible to capture and analyze the potential psychological vulnerability in critical situations.Twitter, prompted by the rapid spread of alternative narratives, started actively warning users about the spread of COVID-19 misinformation. This form of soft moderation comes in two forms as an interstitial cover before the Tweet is displayed to the user or as a contextual tag displayed below the Tweet. We conducted a 319-participants study with both verified and misleading Tweets covered or tagged with the COVID-19 misinformation warnings to investigate how Twitter users perceive the accuracy of COVID-19 vaccine content on Twitter. The results suggest that the interstitial covers work, but not the contextual tags, in reducing the perceived accuracy of COVID-19 misinformation. Soft moderation is known to create so-called "belief echoes" where the warnings echo back, instead of dispelling, preexisting beliefs about morally-charged topics. We found that such "belief echoes" do exist among Twitter users in relationship to the perceived safety and efficacy of the COVID-19 vaccine as well as the vaccination hesitancy for themselves and their children. These "belief echoes" manifested as skepticism of adequate COVID-19 immunization particularly among Republicans and Independents as well as female Twitter users. Surprisingly, we found that the belief echoes are strong enough to preclude adult Twitter users to receive the COVID-19 vaccine regardless of their education level.We investigate the optimal response of unemployment insurance to economic shocks, both with and without commitment. The optimal policy with commitment follows a modified Baily-Chetty formula that accounts for job search responses to future UI benefit changes. As a result, the optimal policy with commitment tends to front-load UI, unlike the optimal discretionary policy. In response to shocks intended to mimic those that induced the COVID-19 recession, we find that a large and transitory increase in UI is optimal; and that a policy rule contingent on the change in unemployment, rather than its level, is a good approximation to the optimal policy.COVID-19 pandemic and the associated lockdown have globally impacted the food-insecure low-income population. link2 A community-based initiative of an NPO - working on malnutrition issues among the below poverty line children in an urban Indian setting - towards adoption of the slum- and shelter-dwelling children, faced challenges during the pandemic in tackling the twofold uncertainties regarding supply capacity reduction and demand surge. This paper extends earlier research on this NPO's pre-COVID-time food assistance program by introducing a robust optimization-based mathematical programming model to determine the donors to engage, donor-to-beneficiary allocations, and the associated optimal donation flows while addressing these uncertainties. The issue of over-conservatism in robust optimization is addressed by parameterizing the decision-maker's uncertainty budget. We present a detailed numerical study on a test problem along with interesting observations elicited by our sensitivity analyses.This article discusses attempts to legitimise real political goals through historical reinterpretations or to divert attention from political crises, using the example of Russian President Putin's historical policy. After briefly outlining the origins of civil society as well as the commercialisation and institutionalisation of historical interest in the post-Soviet countries, the article analyses the examples of the Russian-Estonian monument dispute as well as a dispute over the interpretation of the Second World War between Russia, Ukraine and Lithuania. The historical-political situation in Eastern Europe is characterised as a "battlefield of memories".The article introduces a mathematics education measure in response to the COVID-19 epidemic in China and explores students' degree of approval and perception of digital equity towards the response. After the outbreak of the COVID-19, the Chinese New Century Primary School Mathematics Textbook (NCPM) committee had developed a series of micro classes (abbreviated as NCPM micro classes), and more than 25 million teachers and students in China watched the NCPM micro classes during the 3 months social isolation. Then, students' degree of approval towards the NCPM micro classes and perception of digital equity were examined after social isolation. A total of 132,740 pieces of data were collected from Chinese primary school students. link3 Quantitative analysis of student's degree of approval towards different parts of NCPM micro classes indicated that the introduction, interaction, summary and consolidation, curriculum characteristics, and goal achievement parts of the NCPM micro classes have received high approval from students, and students with higher former achievement perceived a higher degree of approval towards the NCPM micro classes. Furthermore, we found that gender, socioeconomic status, school location, and learning location had no significant impact on students' degree of approval, indicating a digital equity exists. This study helps researchers or educators understand the mathematics education response to the COVID-19 outbreak in China and extends our understanding of primary students' degree of approval and perception of digital equity with these online classes.In the spring of 2020, schools and universities around the world were closed because of the COVID-19 pandemic. The relative lockdown affected more than 1.5 billion learners as teachers and students sheltered at home for several weeks. As schooling moved online, teachers were forced to change how they taught. In the research presented here, we focus on university mathematics professors, and we analyze how their practice, knowledge, and beliefs intertwine and change under these circumstances. More specifically, the context of the pandemic and the relative lockdown provides us with the experimental basis to argue that the new practice affected both knowledge and beliefs of mathematics teachers and that practice, knowledge, and beliefs form a system. Being part of a system, the reactions to change in practice can be of two types, namely, the system as a whole tries to resist change, or the system as a whole changes - and it changes significantly. The research presented here proposes a model for describing and analyzing what we called a teaching system and examines three cases that help to better depict the systemic nature of teaching.
