ABSTRACT
This paper examines whether the Covid-19 pandemic has had a homogeneous or heterogeneous effect on stock returns in India. We consider panel data by using 1,318 companies that are listed on the National Stock Exchange of India. We find that the daily growth rate in Covid-19 cases and Covid-19 deaths are negatively associated with stock returns. Further, we observe that the average stock returns during Lockdown 2 are positive and highly significant, while the returns during Lockdowns 3 and 4 are negative. Moreover, our results show that the chemical, technology, and food and beverage industries earn higher returns. In contrast, the banking and finance, automotive, services, and cement and construction industries yield lower returns for the overall period. Interestingly, all industry groupings in this study earn a positive return during the lockdown period. In particular, the chemical, technology, automotive, metals and mining, and food and beverage industries provide higher returns during the lockdown period. Finally, this study supports the claim that the Covid-19 pandemic has had a heterogeneous effect in the Indian stock markets. © 2022, Academy of Economics and Finance.
ABSTRACT
With its enormous spread, the continuing COVID-19 corona virus pandemic has become a worldwide tragedy. Population vulnerability rises as a result of fewer antiviral medicines and a scarcity of virus fighters. By minimizing physical contact between people, the danger of viral propagation can be reduced. Previously, the distance between two individuals, as well as the number of people breaching the distance, could be computed with alarm. In the proposed methodology, including the existing features in the previous methodology and additionally, the total number of people present in a given frame, as well as the number of people who were violated,non-violated are tallied. The most crucial step in improving social separation detection is to use proper camera calibration. It will produce better results and allow you to compute actual measurable units instead of pixels It can also figure out how many people are in a certain location. As a result, the suggested system will be useful in identifying, counting, and alerting persons who are breaching the specified distance, as well as estimating the number of people in the frame to manage corona spread. © 2022, IFIP International Federation for Information Processing.
ABSTRACT
Environmental monitoring and impact assessment reports are created by compiling and analyzing data. Ensuring that an organization's operations do not harm human health or the natural environment is the primary goal of environmental monitoring. To conserve the earth, safeguard public health, and minimize expenses, environmental monitoring systems are becoming increasingly important. When discussing IoT-enabled environmental monitoring, waste management, air pollution, and extreme weather typically come up. Infectious illness is induced by a newly discovered coronavirus (COVID-19). A mild to severe respiratory sickness is the most common symptom of infection with COVID-19 and does not necessitate any special treatment for most patients. An increased risk of serious sickness is seen in the elderly, as well as individuals who have pre-existing medical conditions. COVID-19, the virus that causes and transmits the disease, can be prevented and slowed down by being educated about it. Using an alcohol-based hand sanitizer or washing your hands often is a good way to keep yourself and others safe from infection. Different people are affected by COVID-19 in various ways. A viral infection usually results in mild to moderate symptoms, and the majority of individuals will be able to heal at home without the need for medical attention. Sensors are used to monitor and record every aspect of the environment in their respective settings. The most commonly utilized sensors include proximity sensors, temperature sensors, smoke sensors, etc. With an ever-increasing population, increasing industrial activity, and rising energy consumption, it is imperative that the environmental monitoring process be made more accurate and efficient by using cuttingedge, automated monitoring applications and devices. It will be a useful tool for monitoring climate change. People, energy, goods, and information will move more efficiently as a result. In addition, it will continue to adapt as scientists and leaders come to new agreements on the actions, we must take to safeguard ourselves from rising temperatures and hazardous climate circumstances. © 2022 Nova Science Publishers, Inc..
