Corona Virus Disease 2019 (COVID-19) is a deadly virus named after severe acute respiratory syndrome coronavirus 2; it affects the respiratory system of the human and sometimes leads to death. The COVID-19 mainly attacks the person with previous lung diseases; the major cause of lung diseases is the exposure to nitrogen dioxide (NO2) for a longer duration. NO2 is a gaseous air pollutant caused as an outcome of the vehicles, industrial smoke and other combustion processes. Exposure of NO2 for long-term leads to the risk of respiratory and cardiovascular diseases and sometimes leads to fatality. This paper aims to analyze the NO2 level impact in India during pre- and post-COVID-19 lockdown. The study also examines the relationship between the fatality rate of humans because of exposure to NO2 and COVID-19.

Spatial analysis has been conducted in India based on the mortality rate caused by the COVID-19 using the data obtained through Internet of Medical things. Meanwhile, the mortality rate because of the exposure of NO2 has been conducted in India to analyze the relationship. Further, NO2 level assessment is carried out using Copernicus Sentinel-5P satellite data. Moreover, aerosol optical depth analysis has been carried out based on NASA’s Earth Observing System data.

The results indicate that NO2 level has dropped 20-year low because of the COVID-19 lockdown. The results also determine that the mortality rate because of long-time exposure to NO2 is higher than COVID-19 and the mortality rate because of COVID-19 may be a circumlocutory effect owing to the inhalation of NO2.

Using the proposed approach, the COVID-19 spread can be identified by knowing the air pollution in major cities. The research also identifies that COVID-19 may have an effect because of the inhalation of NO2, which can severe the COVID-19 in the human body.

The purpose of the study is to highlight the potential of the sensor based smartphone in assessing the covid-19 cases. Coronavirus disease 2019 (COVID-19) is a noxious pandemic affecting the respiratory system of the human and leading to the severe acute respiratory syndrome, sometimes causing death. COVID-19 is a highly transmittable disease that spreads from an infected person to others. In this regard, a smart device is required to monitor the COVID-19 infected patients by which widespread pandemic can be reduced.

In this paper, an electrochemical sensor-enabled smartphone has been developed to assess the COVID-19 infected patients. The data-enabled smartphone uses the Internet of Things (IoT) to share the details with the other devices. The electrochemical sensor enables the smartphone to evaluate the ribonucleic acid (RNA) of COVID-19 without the nucleic acid and feeds the data into the data server by using a smartphone.

The obtained result identifies the infected person by using the portable electrochemical sensor-enabled smartphone, and the data is feed into the data server using the IoT. Whenever an infected person moves outside the restricted zone, the data server gives information to the concerned department.

The developed electrochemical sensor-enabled smartphone gives an accuracy of 81% in assessing the COVID-19 cases. Thus, through the developed approach, a COVID-19 infected person can be identified and the spread can be minimized.

The purpose of this study is to determine whether COVID-19 had an impact on the brand equity of the Top 100 global brands in the Americas, European and Asian regions over the three years of assessment (2020–2022).

A secondary data method (document scanning) was used to gather the study’s data from Brand Finance’s Global 500 annual reports from 2019 to 2022. The data for this study was analysed using the IBM Statistical Package for Social Science (SPSS) Statistics for Windows, Version 26.0. The data were subjected to a descriptive test and one-way analysis of variance.

The findings showed that most of the Top 100 global brands from the Americas, Europe and Asia experienced little or no impact due to COVID-19. Thus, no significant differences were found to exist among the Top 100 global regional brands due to COVID-19 in the years 2020 and 2021. However, there is a significant difference in 2022 due to its small effect size.

The findings of this paper contribute to brand equity literature and global branding literature in the context of COVID-19. This paper innovatively frames brand equity and provides guidelines to help brands sustain their financial-based brand equity during a worldwide crisis.

The COVID-19 pandemic necessitated teleworking, which inadvertently led to an impaired communication between supervisors and employees, resulting in abusive supervision. Drawing on the conservation of resources (COR) theory and the social identity theory, this study aims to address this negative association by examining the mediating role of state mindfulness and the moderating role of COVID-19 corporate social responsibility (CSR) in the relationship between abusive supervision and counterproductive work behaviors.

This research employs both qualitative and quantitative research designs. Data collection involved an experimental design with 117 participants (Study 1), a cross-sectional survey with 243 participants (Study 2) and semi-structured interviews with 24 full-time employees (Study 3).

The results reveal that state mindfulness acts as a mediator in the positive relationship between abusive supervision and counterproductive work behaviors (CWB). Furthermore, COVID-19 CSR mitigates the relationship between abusive supervision and CWB within the organization, but not with the supervisor. Additionally, COVID-19 CSR moderates the impact of abusive supervision on state mindfulness.

The results emphasize the crucial role of CSR when employees encounter abusive supervision during the COVID-19 pandemic. Organizations and managers should adopt appropriate strategies to enhance employees' perception of CSR. Prioritizing the cultivation of state mindfulness is also recommended, and organizations can provide short-term mindfulness training to improve employees' state mindfulness.

This research contributes to the understanding of abusive supervision and CWB in the context of forced teleworking.

The purpose of this paper is to compare the performance of Iran and G7 countries in the management of the COVID-19 crisis.

The indicators and statistics provided by the Oxford Government Response Tracker are used in this research. Sixteen indicators and their related items have been analyzed for eight countries including Iran, Canada, Germany, France, Great Britain, Italy, Japan, and the United States. For data analysis, Multivariate analysis of variance (MANOVA) and Tukey’s post hoc test were applied, and structural equation modeling performed with the help of SPSS and Smart-PLS software.

The results show that 8 indicators of closing schools, cancellation of public events, restriction of gatherings, restriction of domestic travel, restriction of international travel, reduction of household debt, testing policy, and contact tracing, have an effect on the number of deaths in the countries under review. The results also showed that the countries exhibit behaviors outside their normal culture during the crisis.

This paper will be helpful for scholars, as well as policymakers when making policies on the appropriate responses to COVID-19 and similar pandemics.

This study aims to investigate the impact of coronavirus disease 2019 (COVID-19) on the relationship between buyer firms' corporate social responsibility (CSR) activities toward business partners, such as suppliers, and firm value. The study further explores the role of ownership structure in shaping this relationship.

The authors employ a difference-in-differences (DID) regression method to distinguish between the periods before and during the COVID-19 crisis. The authors utilize data from firms listed on the Korean stock market between 2013 and 2020.

The results show that CSR activities for suppliers have a positive impact on the value of buyer firms. Furthermore, this positive relationship is amplified during the COVID-19 period. In addition, the study finds that the positive relationship is more prominent in samples with higher ownership by controlling shareholders or foreign investors.

Overall, this study makes a valuable contribution to the existing literature by examining the positive effects of CSR activities on firm value and by shedding light on the role of ownership structure in influencing these effects. Additionally, the study emphasizes the significance of CSR activities for business partners in mitigating supply chain disruptions during the COVID-19 pandemic.

COVID-19 disrupted the lives of consumers across the globe, and the retail sector has been one of the hardest hits. The impact of COVID-19 on consumers' retail choice behaviour and retailers' responses has been studied in detail through multiple lenses. Now that the effect of COVID-19 is abating, there is a need to consolidate the learnings during the lifecycle of COVID-19 and set the agenda for research post-COVID-19.

Scopus database was searched to cull out academic papers published between March 2020 and June 6, 2022, using keywords; shopping behaviour, retailing, consumer behaviour, and retail channel choice along with COVID-19 (171 journals, 357 articles). Bibliometric analysis followed by selective content analysis was conducted.

COVID-19 was a black swan event that impacted consumers' psychology, leading to reversible and irreversible changes in retail consumer behaviour worldwide. Research on changes in consumer behaviour and consumption patterns has been mapped to the different stages of the COVID-19 lifecycle. Relevant research questions and potential theoretical lenses have been proposed for further studies.

This paper collates, classifies and organizes the extant research in retail from the onset of the COVID-19 pandemic. It identifies three retail consumption themes: short-term, long-term reversible and long-term irreversible changes. Research agenda related to the retailer and consumer behaviour is identified; for each of the three categories, facilitating the extraction of pertinent research questions for post-COVID-19 studies.

This paper investigates the probable differential impact of the confirmed cases of COVID-19 on the equities markets of G7 and Nordic countries to ascertain possible interdependencies, diversification and safe haven prospects in the era of the COVID-19 pandemic over the short-, intermediate- and long-term horizons.

The authors apply a unique methodology in a denoised frequency-domain entropy paradigm to the selected equities markets (Li et al. 2020).

The authors’ findings reinforce the operability of the entrenched market dynamics in the COVID-19 pandemic era. The authors divulge that different approaches to fighting the pandemic do not necessarily drive a change in the deep-rooted fundamentals of the equities market, specifically for the studied markets. Except for an extreme case nearing the end (start) of the short-term (intermediate-term) between Iceland and either Denmark or the US equities, there exists no potential for diversification across the studied markets, which could be ascribed to the degree of integration between these markets.

The authors’ findings suggest that politicians should pay closer attention to stock market fluctuations as well as the count of confirmed COVID-19 cases in their respective countries since these could cause changes to market dynamics in the short-term through investor sentiments.

The authors measure the flow of information from COVID-19 to G7 and Nordic equities using the entropy methodology induced by the Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (ICEEMDAN), which is a data-driven technique. The authors employ a larger sample period as a result of this, which is required to better comprehend the subtleties of investor behaviour within and among economies – G7 and Nordic geographical blocs – which largely employed different approaches to fighting the COVID-19 pandemic. The authors’ focus is on diverging time horizons, and the ICEEMDAN-based entropy would enable us to measure the amount of information conveyed to account for large tails in these nations' equity returns. Furthermore, the authors use a unique type of entropy known as Rényi entropy, which uses suitable weights to discern tailed distributions. The Shannon entropy does not account for the fact that financial assets have fat tails. In a pandemic like COVID-19, these fat tails are very strong, and they must be accounted for.

The present conceptual paper evinces a new understanding of the present and future of the tourist city in a post-COVID-19 world. The pandemic has wreaked havoc in the tourism industry as well as global trade. The world, at least as we know, is debating the next recovery steps for 2023.

In this conceptual paper, the authors explore the substantial shifts faced by the urban areas during and post-COVID-19 pandemic. The disposed [and imposed] restrictive measures have affected negatively not only mobilities but also the urban landscape. The tourist-city, at least as it was imagined by J. Urry, has invariably set the pace to a ghost-city. In this new landscape, citizens are confined to be at home.

The tourist city has faced substantial changes. The authors dubbed the term ghost city to give some reflections on the radical changes urban zones are experiencing during 2020 and 2021. Classic notions as “the Other,” “globalization” and the “city” are in motion. The borders of some nations are being re-drawn while some radicalized voices and movements flourish.

The authors introduce readers to the literature about the tourist city, which offers a perfect landscape for attraction, consumption and protest. The tourist city has been developed by scholars as a sign of a globalizing process that laid the foundations toward a new understanding of urban zones.

The present paper discusses critically the problem of COVID-19 and its severe restriction of free circulation and the forms in which the city is lived and dwelled. We were pressed to live our proximity through the lens of a screen or using digital media. The basic rights that are historically characterized by the legal architecture of the nation-state – which is based on high mobilities and the right of traveling – were suddenly suspended.

The authors deal with the problems of sociology to study the ghost city, which include not only the dilemmas revolving around the health passport but also the introduction of technology in formalizing the creation of a surveillance society that scrutinizes and, at the same time, entertains modern citizens, in a new culture where the “Other” becomes an undesired guest.

la presente nota intenta explicar el futuro de la ciudad turística en un contexto posterior al COVID-19. Habiendo dicho eso debe destacarse que la pandemia ha hecho estragos en la industria turística como así también en el comercio global. Los especialistas sugieren que el mundo global a los niveles iniciales anteriores a la pandemia se recuperará a mediados de 2023.

el presente trabajo es una discusión conceptual que focaliza en los efectos del COVID-19 en la imagen de la ciudad turística.

la ciudad turística atraviesa por estos días cambios radicales que afectan su naturaleza. Usamos el término ciudad fantasma [ghost city] para referirnos a los efectos socio-culturales a largo alcance de las medidas restrictivas para frenar el avance de la enfermedad. Nociones clásicas como “el Otro,” y la globalización deben ser re-conceptualizadas a raíz de la reconfiguración de las nuevas fronteras y de discursos racistas y radicalizados tendientes a negar a ese “Otro” diferente.

el trabajo introduce a los lectores en la literatura especializada destacando las tensiones entre la ciudad turística y la ciudad como lugar de protesta y negociación. La ciudad turística es una creación directa del proceso globalizador que ha configurado las zonas urbanas.

el presente trabajo discute críticamente como la crisis del COVID-19 ha marcado la forma de relacionarnos en la circulación. Estamos forzados a vivir nuestra proximidad por intermedio de las redes digitales, y un televisor, alterando las bases mismas del estado de libre tránsito y los derechos fundamentales a la circulación.

entre unos de los temas más originales que aborda el trabajo se encuentra el pasaporte sanitario, documento emitido por el estado para dar movilidad al sujeto. El pasaporte sanitario transforma no sólo la forma de validad la identidad, sino que introduce la tecnología al servicio de vigilancia del estado sobre el sujeto. En el mundo post COVID-19 el turista se transformado en un huésped indeseado.

The purpose of this research work is to examine the financial effect of supply chain disruptions (SCDs) caused by coronavirus disease 2019 (COVID-19) and how the magnitude of such effects depends on event time and space that may moderate the signaling environment for shareholder behaviors during the pandemic.

This study analyses a sample of 206 SCD events attributed to COVID-19 made by 145 publicly traded firms headquartered in 21 countries for a period between 2020 and 2021. Change in shareholder value is estimated by employing a multi-country event study, followed by estimating the differential effect of SCDs due to the pandemic by event time and space.

On average, SCDs due to pandemic decrease shareholder value by −2.16%, which is similar to that of pre-pandemic SCDs (88 events for 2018–2019). This negative market reaction remains unchanged regardless of whether stringency measures of the firm's country become more severe. Supply-side disruptions like shutdowns result in a more negative stock market reaction than demand-side disruptions like price hikes. To shareholder value, firm's upstream or downstream position does not matter, but supply chain complexity serves as a positive signal.

This study provides the first empirical evidence on the financial impact of SCDs induced by COVID-19. Combining with signaling theory and event system theory, this study provides a new boundary condition that explains the impact mechanism of SCDs caused by the pandemic.
