ABSTRACT
New approaches and methods would redefine the global corporate and economies as the pandemic has struck the world. India has been under lock down for the last four months is still pondering its ways and means to handle this challenge effectively. With profits plummeting and businesses in chaos, the entire business community has to rise to the occasion to face this mammoth problem. This research attempts to study the challenges and issues that are hampering effective talent management for talent retention during this pandemic. The solution lies in effective coordination with employer and employee with talent management and retention practices. This study is quantitative and empirical while being exploratory and conclusive. The study intends to explore the dimensions of talent management and talent retention practices for Indian Inc. In this study, stratified random sampling was done, and 100 employees, who work in Indian corporate from various states was, administered a questionnaire. The collected data were analyzed using SPSS, correlation, regression, and confirmatory factor analysis. It was found that family and family priorities occupy the employee's mind during these COVID-19 times. The organizational policies and frameworks must orient so that the employee's health and safety are the top priorities. The modified work environment, work culture, and priorities would help in employee retention. An empirical framework is also provided for Indian enterprises on talent management and retention after the COVID-19 pandemic.
ABSTRACT
Since the outbreak of the COVID-19 epidemic, several control strategies have been proposed. The rapid spread of COVID-19 globally, allied with the fact that COVID-19 is a serious threat to people's health and life, motivated many researchers around the world to investigate new methods and techniques to control its spread and offer treatment. Currently, the most effective approach to containing SARS-CoV-2 (COVID-19) and minimizing its impact on education and the economy remains a vaccination control strategy, however. In this paper, a modified version of the susceptible, exposed, infectious, and recovered (SEIR) model using vaccination control with a novel construct of active disturbance rejection control (ADRC) is thus used to generate a proper vaccination control scheme by rejecting those disturbances that might possibly affect the system. For the COVID-19 system, which has a unit relative degree, a new structure for the ADRC has been introduced by embedding the tracking differentiator (TD) in the control unit to obtain an error signal and its derivative. Two further novel nonlinear controllers, the nonlinear PID and a super twisting sliding mode (STC-SM) were also used with the TD to develop a new version of the nonlinear state error feedback (NLSEF), while a new nonlinear extended state observer (NLESO) was introduced to estimate the system state and total disturbance. The final simulation results show that the proposed methods achieve excellent performance compared to conventional active disturbance rejection controls.

The COVID-19 outbreak has destructively affected the education system over the world and brought about prominent alterations in the traditional systems of teaching and learning. In order to flatten the curve of disease transmission, several countries have resorted to online classes for students. Apart from the benefits of this strategy, there exists a chance of developing ocular complications in students those are continuously viewed the digital screen without any break. T-test and frequency analysis was used to find out the link between the digital electronic gadgets and eye strains. SPSS version 24.0.0 was used for all the statistical analyses. Here we assessed the various prominent factors behind the development of complications in eyes instigated by the electronic gadgets with special inference on the type of electronic gadgets, time spend, distance, type of usage, kind of posture, light condition, stress, and kind of symptoms towards digital eye strains. One of the major fact that has been emerged in this investigation is that the usage of electronic gadgets for online classes purposes have greatly increased than the other usage. The use of electronic gadgets for work and educational purposes has been recognized as a normal activity among individuals. With the extensive prevalence of developing digital eye strain in the students, it is paramount that the results of this investigation can be used for research purposes as strong research evidence to prevent the complications allied with eyes.
