Optimal policy for uncertainty estimation concurrent with decision making.

Decision making often depends on vague information that leads to uncertainty, which is a quantity contingent not on choice but on probability distributions of sensory evidence and other cognitive variables. Uncertainty may be computed in parallel and interact with decision making. Here, we adapt the classic random-dot motion direction discrimination task to allow subjects to indicate their uncertainty without having to form a decision first. The subjects' choices and reaction times for perceptual decisions and uncertainty responses are measured, respectively. We then build a value-based model in which decisions are based on optimizing value computed from a drift-diffusion process. The model accounts for key features of subjects' behavior and the variation across the individuals. It explains how the addition of the uncertainty option affects perceptual decision making. Our work establishes a value-based theoretical framework for studying uncertainty and perceptual decisions that can be readily applied in future investigations of the underlying neural mechanism.

COVID-19 Pandemic Implications for Corporate Sustainability and Society: A Literature Review.

The paper revises the ample empirical and theoretical literature on sustainable organizational growth and strategic leadership relating to the critical aspects of the ongoing pandemic, including poverty, social responsibility, public health, and organizational and managerial innovation. Drawing from available COVID-19, management, and sustainable leadership publications released from 2020 to 2021, this paper considers influential studies exploring core business concepts, principles, philosophies, and activities for accelerating, stimulating, and nurturing social and corporate sustainability. The study analyzed the characteristics and interrelation of 133 articles through bibliometric and literature systemization techniques. We shed light on the significant influence COVID-19 has had on financial, operational, and psychological solvency and organizational health to elucidate expectations and implications for businesses worldwide concerning the long-term financial and functional impact of COVID-19. An overview of the relevant studies on the individual, organizational, and external factors relating to novel disease's relation to sustainability are provided. We emphasize the need for digital transformation following the COVID-19 upheaval and throughout the upcoming years. Some of the generally employed techniques in response to adversity entail portfolio diversification, service delivery innovation, product redesigning, new market development, partnering with competitors and/or complementary service providers, synergizing with other stakeholders, and open innovation.
