In early 2020, the novel coronavirus (COVID-19) spread to the United States and upended normal life. Using trip-level data on over 17 million taxi rides taken in Chicago from 2018-2021, I document how tipping behavior changed during the COVID-19 pandemic. I find that the average non-zero tip increased by almost 2 percentage points, from roughly 26% to 28% of the taxi fare. Meanwhile, the likelihood that a passenger left a tip at all declined by roughly 5 percentage points, down from a pre-pandemic likelihood of 95%. My preferred specification suggests that the effect on the intensive margin dominates that in the extensive margin, leading to an aggregate increase in tipping generosity during the pandemic. I leverage granularity in the data to explore the mechanisms behind these trends and offer two explanations consistent with thedata. First, passengers responded to the two economic shocks of the pandemic – unemployment and savingsoverhangs – by varying their tipping rates accordingly. Second, passengers internalized the increased risk of COVID-19 infection as an additional cost for taxi drivers and increased their tips as compensation. My analysis testifies to the sustainability of tipping in times of crises and offers theoretical insight into what drives tipping behavior.

Abstract Background. A novel, human-infecting coronavirus causing CoVID-19 was first identified in Wuhan, China in late December, 2019. Within a short span of time more the virus has recorded more than 1 million deaths world-wide. This study is designed to address the overall evolutionary process of the novel Coronavirus complete genomes. Addressing the complexity and huge population size, network-based approaches are used in mapping samples to their reported locations. Results. Total of 473 complete human-coronavirus genomes representing 20 different countries are studied including 17 states from the United States and samples collected from the Cruise-diamond princess. The phylodynamic network of global-scale is classified into five clusters contained two clusters U1 and U2 of the USA samples. Cluster B is a shared cluster of China and the USA while A and C are of diverse nature. We found that Chinese samples aggregated in cluster A and B which aided in retaining the homogeneous viral genomic pool. In contrast, samples from the USA and Spain were split into distinct clusters indicating multiple port entries and a possibility in implying a delay in quarantine measures. Among the samples from the USA, we found that sequences reported from Washington and Virginia are scattered indicating evolutionary diversity.Conclusion. This report provides insight into the transmission pattern of CoV2 which is complicated to evaluate exclusively through conventional surveillance means. Our data not only identify the transmission network but also suggest that the severity of the disease is linked to the spatial diversity of infection.

The novel coronavirus communicative modalities are ever-emergent and infinitely adaptable systems of the new normal state of mind and play. By focusing on specificities found in the corpus extracted from three leading Bosnian and Herzegovinian (B&H) newspapers, the paper attempts to merge the predominant theoretical insight into a mixture of conceptual and critical theories of language. The focus of the paper is two-fold. The first one is targeted at testing the extracted theoretical posits on the linguistic corpora. The second aims at challenging the notions of togetherness and separateness in the B&H society by mirroring them through the prism of Covid-19 newspaper reports. The results of the corpus analysis suggest that it is still possible to draw a line between the notions in accordance with the specific geographical regions from which the data are drawn.

Abstract Since the spring of 2020 SARS-CoV-2, the novel coronavirus, has upended lives and caused a rethinking of nearly all social behaviors in the United States. This paper examines the ways in which the pandemic, shutdown, and gradual move towards “normal” have laid bare and obfuscated societal pressures regarding running out of time as it pertains to the residential university experience. Promised by movies, television, and older siblings and friends as a limited-time offer, the “typical” college experience is baked into the U.S. imaginary, reinforcing a host of notions of who “belongs” on campus along lines of race, class, and age. Fed a vision of what their whole lives “should be”, students who enter a residential four-year college are already imbued with a nostalgia for what is yet to come, hailed, in Althusser’s (2006[1977]) sense, as university subjects even before their first class. The upheaval of that subjecthood during the pandemic has raised important questions about the purpose of the college experience as well as how to belong to a place that is no longer there.

COVID-19, also known as the ‘novel coronavirus disease 2019’, is a respiratory illness and the causative pathogen is officially named as ‘SARS-CoV-2’. Infections with SARS-CoV-2 have now been amplified to a global pandemic – as of April 3, 2020, nearly 1,018,000 cases have been confirmed in more than 195 countries, including more than 300,000 cases within the United States. Public safety guidelines are followed worldwide to stop the spread of COVID-19 and stay healthy. Despite COVID-19 is a respiratory illness with mode of invasion through the respiratory tract, not the gastrointestinal tract, an average food consumer is anxious and concerned about the food safety. Could an individual catch the deadly contagious COVID-19 from groceries brought home from the supermarket – or from the next restaurant takeout order? This brief review elucidates the epidemiology and pathobiological mechanism(s) of SARS-CoV-2 and its implications in food-borne infections, transmission via food surfaces, food processing and food handling.

Abstract Background: The outbreak of coronavirus disease (COVID-19) was caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), through its surface spike glycoprotein (S-protein) recognition on the receptor Angiotensin-converting enzyme 2 (ACE2) in humans. However, it remains unclear how genetic variations in ACE2 may affect its function and structure, and consequently alter the recognition by SARS-CoV-2. Methods: We have systemically characterized missense variants in the gene ACE2 using data from the Genome Aggregation Database (gnomAD; N = 141,456). To investigate the putative deleterious role of missense variants, six existing functional prediction tools were applied to evaluate their impact. We further analyzed the structural flexibility of ACE2 and its protein-protein interface with the S-protein of SARS-CoV-2 using our developed Legion Interfaces Analysis (LiAn) program.Results: Here, we characterized a total of 12 ACE2 putative deleterious missense variants. Of those 12 variants, we further showed that p.His378Arg could directly weaken the binding of catalytic metal atom to decrease ACE2 activity and p.Ser19Pro could distort the most important helix to the S-protein. Another seven missense variants may affect secondary structures (i.e. p.Gly211Arg; p.Asp206Gly; p.Arg219Cys; p.Arg219His, p.Lys341Arg, p.Ile468Val, and p.Ser547Cys), whereas p.Ile468Val with AF = 0.01 is only present in Asian.Conclusions: We provide strong evidence of putative deleterious missense variants in ACE2 that are present in specific populations, which could disrupt the function and structure of ACE2. These findings provide novel insight into the genetic variation in ACE2 which may affect the SARS-CoV-2 recognition and infection, and COVID-19 susceptibility and treatment.

The public health crisis created by the COVID-19 pandemic has spurred a deluge of scientific research aimed at informing the public health and medical response to the pandemic. However, early in the pandemic, those working in frontline public health and clinical care had insufficient time to parse the rapidly evolving evidence and use it for decision-making. Academics in public health and medicine were well-placed to translate the evidence for use by frontline clinicians and public health practitioners. The Novel Coronavirus Research Compendium (NCRC), a group of >60 faculty and trainees across the United States, formed in March 2020 with the goal to quickly triage and review the large volume of preprints and peer-reviewed publications on SARS-CoV-2 and COVID-19 and summarize the most important, novel evidence to inform pandemic response. From April 6 through December 31, 2020, NCRC teams screened 54 192 peer-reviewed articles and preprints, of which 527 were selected for review and uploaded to the NCRC website for public consumption. Most articles were peer-reviewed publications (n = 395, 75.0%), published in 102 journals; 25.1% (n = 132) of articles reviewed were preprints. The NCRC is a successful model of how academics translate scientific knowledge for practitioners and help build capacity for this work among students. This approach could be used for health problems beyond COVID-19, but the effort is resource intensive and may not be sustainable in the long term.

Occupying administrative positions in any organization is an enormous and difficult task, especially in universities and other higher institutions of learning where the culture and conventional practices demand shared governance and collective decision making. Even more complex is when such positions are occupied by minorities who need to weigh a lot of factors in their decision making in order to effectively navigate and accomplish their duties and objectives. This chapter offers a brief theoretical insight into administrative leadership in the academy. More importantly, it provides the narratives of the personal experiences of administrators in the United States and Guyana; people whose gender and racial backgrounds categorize them as minorities. Sharing such experiences aligns with the purpose of this book and also provides some learning opportunities for people in the diaspora who aspire to become administrators in the academy and minorities who are currently doing the job.

Novel Coronavirus

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a betacoronavirus that causes the novel coronavirus disease 2019 (COVID-19), is highly transmissible and pathogenic for humans and may cause life-threatening disease and mortality, especially in individuals with underlying comorbidities. First identified in an outbreak in Wuhan, China, COVID-19 is affecting more than 185 countries and territories around the world, with more than 15,754,651 confirmed cases and more than 640,029 deaths. Since December 2019, SARS-CoV-2 transmission has become a global threat, which includes confirmed cases in all 50 states within the United States (US). As of 25 July 2020, the Johns Hopkins Whiting School of Engineering Center for Systems Science and Engineering reports more than 4,112,651 cases and 145,546 deaths. To date, health disparities are associated with COVID-19 mortality among underserved populations. Here, the author explores potential underlying reasons for reported disproportionate, increased risks of mortality among African Americans and Hispanics/Latinos with COVID-19 compared with non-Hispanic Whites. The author examines the underlying clinical implications that may predispose minority populations and the adverse clinical outcomes that may contribute to increased risk of mortality. Government and community-based strategies to safeguard minority populations at risk for increased morbidity and mortality are essential. Underserved populations living in poverty with limited access to social services across the US are more likely to have underlying medical conditions and are among the most vulnerable. Societal and cultural barriers for ethnic minorities to achieve health equity are systemic issues that may be addressed only through shifts in governmental policies, producing long-overdue, substantive changes to end health care inequities.

Novel Coronavirus

The novel coronavirus reached the United States and Canada almost at the same time. The first reported American case was January 20, 2020, and in Canada it was January 15, 2020 (Canada, 2020; Holshue et al., 2020). Yet, the response to this crisis has been different in the two countries. In the US, President Donald Trump, prominent Republicans, and conservative media initially dismissed the dangers of COVID-19 (Stecula, 2020). The pandemic became politicized from the early days, and even though Trump and Republicans have walked back many of their initial claims, there continue to be media reports of partisan differences in public opinion shaped by that early response. At the same time, the response in Canada has been mostly characterized by across-the-board partisan consensus among political elites (Merkley et al., 2020).

The Relationship

Background: The first outbreaks of the new coronavirus disease, named COVID-19, occurred at the end of December 2019. This disease spread quickly around the world, with the United States, Brazil and Mexico being the countries the most severely affected. This study aims to analyze the relationship between different publications and their authors through citation networks, as well as to identify the research areas and determine which publication has been the most cited. Methods: The search for publications was carried out through the Web of Science database using terms such as “COVID-19” and “SARS-CoV-2” for the period between January and July 2020. The Citation Network Explorer software was used for publication analysis. Results: A total of 14,335 publications were found with 42,374 citations generated in the network, with June being the month with the largest number of publications. The most cited publication was “Clinical Characteristics of Coronavirus Disease 2019 in China” by Guan et al., published in April 2020. Nine groups comprising different research areas in this field, including clinical course, psychology, treatment and epidemiology, were found using the clustering functionality. Conclusions: The citation network offers an objective and comprehensive analysis of the main papers on COVID-19 and SARS-CoV-2.
