Effects of Virus Risk on Corporate Sustainability: Literature Review

COVID-19 prompted scientists, experts, and health professionals to join efforts in an attempt to find effective ways to mitigate risks, curb the consequences, and balance the trade-offs in a dynamic business environment characterized by sudden changes in market demand unpredictability, financial crashes, and profound adversities (van Barneveld et al. in Econ Labour Relat Rev 31:133–157, 2020). Inflation rates and energy costs have increased all over the world. While education has evolved into distance education with the COVÍD announcement, unfortunately, two years have gone down in history as a loss for students who do not have computers, smart phones and internet facilities. In this study, recent published articles about the effects of COVID-19 on different sectors and economy were examined. It seems that while health and information technologies have profited from the COVID period, the tourism sector has taken a big hit. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Knowledge, attitudes, practice of people toward the COVID-19 pandemics, and its impact in Afghanistan.

COVID-19 pandemic disrupted the social and economic norms. Knowledge, Attitude and Practices studies are used to address the information gap for further strategic decision making to control the pandemic. This study aimed to find the level of Knowledge, Awareness, Attitudes, and behavioral practices of the people of Afghanistan about the COVID-19 and its impact on health and socio-economic dimension of their routine lives. We used a cross-sectional method with two stage sampling design. Data analysis was performed using SPSS v.20. The survey focused on adults including men and women all over the country to represent the country, including the urban and rural areas. Most of the respondents are in the age group of 21-30 years (46.5%); 60.15% of the participants are married. Almost 75% of females and 84% of males were literate and most participants have a bachelor's degree (34%). More than 80% of participants knew they can prevent themselves from contacting COVID-19 through hand washing frequently with soap and water and wearing a mask. More than 80% of participants responded that they would go for a lab test for detection of the virus as well as COVID-19 vaccination if it is available. Almost 35% reported always wearing a mask to prevent COVID-19 transmission; more than half of participants always wash their hands, more than 60% of them do not touch their eyes, nose, and mouth frequently. Nearly 60% of participants indicated that their household had problems satisfying food needs partly during the COVID-19 pandemic. Nearly half of participants believed that the government was successful in applying lockdown measures and in awareness rising (56.8 and 69.8%). The study findings provide some useful insight about the KAP of communities in Afghanistan, which could assist policy makers in public health to design and implement interventions based on the information gaps reported.

An uncertainty measure based on Pearson correlation as well as a multiscale generalized Shannon-based entropy with financial market applications

In this research, we intended to employ the Pearson correlation and a multiscale generalized Shannon-based entropy to trace the transition and type of inherent mutual information as well as correlation structures simultaneously. An optimal value for scale is found to prevent over smoothing, which leads to the removal of useful information. The lowest Singular Value Decomposition Multiscale Generalized Cumulative Residual Entropy (SVDMWGCRE), or SVD Entropy (SVDE), is obtained for periodic–chaotic series, generated by logistic map;hence, the different dynamic, correlation structures, and intrinsic mutual information have been characterized correctly. It is found out that the mutual information between emerging markets entails higher sensitivity, and moreover emerging markets have demonstrated the highest uncertainty among investigated markets. Additionally, the fractional order has synergistic effects on the enhancement of sensitivity with the multiscale feature. According to the logistic map and financial time series results, it can be inferred that the logistic map can be utilized as a financial time series. Further investigations can be performed in other fields through this financial simulation. The temporal evolutions of financial markets are also investigated. Although the results demonstrated higher noisy information for emerging markets, it was illustrated that emerging markets are getting more efficient over time. Additionally, the temporal investigations have demonstrated long-term lag and synchronous phases between developed and emerging markets. We also focused on the COVID-19 pandemic and compared the reactions of developing and emerging markets. It is ascertained that emerging markets have demonstrated higher uncertainty and overreaction to this pandemic.

The Economic Effects of China’s Distribution Industry: An Input-Output Analysis

This study contributes by analyzing the economic effects of China’s distribution industry based on China’s 2012 and 2017 input-output data. It analyzes changes in the forward and backward linkage effect over a five-year period in accordance with the Chinese government’s distribution industry policy. The coefficients of the effects of the Chinese distribution industry, using Input-Output Tables and a comparative analysis of the sensitivity of dispersion, were determined. In terms of the coefficient of influence, most of the sectors that ranked high in 2012 are related to manufacturing, except for lodging and catering. The sensitivity and influence coefficients indicate that the top-ranked sectors in 2012 were more affected by the raw materials and energy essential for manufacturing development than by the services sector.

The Economic Effect of the Steel Industry on Sustainable Growth in China—A Focus on Input–Output Analysis

The purpose of this study is to analyze the economic ripple effects caused by the supply-side reforms on China’s steel industry. To this end, using the 2012 and the 2017 China Input–Output Tables, this study analyzes the economic ripple effect of the Chinese steel industry caused by its supply-side reform. In this study, the influence coefficients (rear-linked effect) and the sensitivity coefficients (forward-linked effect), conceptualized by Leontief, are used as research tools to analyze the ripple effects of the Chinese steel industry. The analysis results are as follows. First, the fact that 2012 ranked high in professional equipment and meter manufacturing shows that the Chinese government’s supply-side reforms are effective and creating the required shift from traditional manufacturing to qualitative growth. Second, in terms of the sensitivity coefficient, in 2012, most of the top industries contributed significantly to the development of the Chinese economy. The originality of this study is as follows. The input production analysis used in this paper is a methodology mainly used in the steel, coal, automobile, and petrochemical industries, which clearly distinguishes the front and rear industries. Additionally, this study is a novel attempt at comparative research on the Chinese steel industry between 2012 and 2017.

Closer to or further from the new normal? business approach through social media analysis.

The outbreak of COVID-19 has led to radical change in all social and economic spheres and, even today, the scope of the pandemic cannot be detailed. This unprecedent situation is challenging the global world but particularly for business. The packages of measures internationally imposed as restrictions on commercial activity, isolation and social distancing mean that business should face a transformation in order to survive in each stage of the crisis. For this purpose, a content analysis with an initial dataset with 2,610 tweets of the most representative Spanish entrepreneurial organizations was carried out in key periods of the pandemic. The findings highlight that there are collective concerns with emotional burden in the business sector that encourage action despite confusion and uncertainty. Generalized distrust of policies led business organizations to insist on innovation and adaptation as the best tools to overcome the economic effect of the crisis.

COVID-19 in Switzerland and Liechtenstein: A Cross-Sectional Survey among Dentists' Awareness, Protective Measures and Economic Effects.

The aim of this observational cross-sectional study was to gain information on the awareness; protective measures and economic effects of dentists in Switzerland during the global COVID-19 pandemic. All dentist were members of the Swiss Dental Association SSO from all over Switzerland-including all Swiss cantons and Liechtenstein-and received a previously calibrated questionnaire as an ad hoc online version. The questionnaire was divided into four parts: personal data; precautionary measures; awareness; perception. In total, 1324 questionnaires were analyzed; the response rate was 30.59% (ntotal = 4328). Participants stated in less than 2% common symptoms/signs of COVID-19; of which only fatigue was statistically significant (p < 0.01). A small number of dentists reported a positive test (0.91%; n = 12) or having one or more symptoms (2.65%; n = 35) of COVID-19 during the pandemic; whereas only 6.71% (n = 87) of the participants reported having treated SARS-CoV-2 infected patients. High prevalence areas were only medium-large and large Swiss cantons (p < 0.01). Face filter (FFP2/FFP3) masks were used by about half of the dentists, while disposable visor was rarely used. The majority of dentists had to reduce the dental practice activity to a minimum of 0-10% (n = 923; 69.98%) due to the lockdown. This economic impact forced 1.4% (n = 18) to close their practice permanently or by the end of 2020 due to the economic situation. These results can be helpful to better prepare dental practices for future outbreaks of infection (e.g., prophylactic storage of additional protective measures), define the best strategy and organize the dental workforce. Political decision-makers should consider drastic economic effects when deciding on drastic measures such as "lockdown", which can lead to practice closures and unemployment of dental staff after only a few weeks. This should be taken into account, especially with regard to possible financial assistance to severely impaired dental practices to maintain a high level of dental care.

A review: Epidemiology, pathogenesis and prospect in developing vaccines for novel Coronavirus (COVID-19).

In December 2019, a large number of coronavirus cases were emerged in Wuhan, Hubei Province, China and rapidly spread to different countries and territories around the world within four months. The World Health Organization (WHO) declared this outbreak as a global health emergency. The spread of COVID-19 over globe is highly contagious; they transmitted from person-to-person through small droplets of infected person. Many diagnosis and treatment methods have been implemented to reduce and control the outbreak. Efforts have been made to develop coronavirus vaccine against S protein or spike glycoprotein of coronavirus. COVID-19 outbreak will affect the Gross Domestic Product (GDP) of the world. At the time of preparing manuscript, total number of active cases reaches to more than 8.9 million and confirmed death reaches to approx. 4.6 lakh. This article highlights the ongoing research and advances in designing vaccine and therapeutics against COVID-19 and also focusing on the epidemiology, transmission, future direction and control the spread of infectious diseases.
