abstract present study aims to identify influential dimensions affecting level of entrepreneurs' decision maker cognitive complexity with regard to the importance of cognition and its complex pattern on the process of entrepreneurial decision making. qualitative stage of this mix method research was conducted at early stage by formation of a focus group consisted of superior entrepreneurs in 20...

This paper investigates the link between the optimal level of non–financial firms’ liquid assets and uncertainty. We develop a partial equilibrium model of precautionary demand for cash that shows that firms are likely to change their liquidity ratio in response to changes in uncertainty. We test this proposition using a panel of non–financial US firms drawn from COMPUSTAT quarterly database co...

In this article, we analyze the impact of uncertainty on the hiring process. We show the connection between models of statistical discrimination where uncertainty can work against groups that have less reliable indicators of future productivity and models of option value where uncertainty about future productivity can be beneficial for these groups. These models generate hypotheses about the re...

OBJECTIVES Racial differences in self-rated health at older ages are well documented. African Americans consistently report poorer health, even when education, income, and other health status indicators are controlled. The extent to which neighborhood-level characteristics mediate this association remains largely unexplored. We ask whether neighborhood social and economic resources help to expl...

Catastrophic regime shifts in complex natural systems may be averted through advanced detection. Recent work has provided a proof-of-principle that many systems approaching a catastrophic transition may be identified through the lens of early warning indicators such as rising variance or increased return times. Despite widespread appreciation of the difficulties and uncertainty involved in such...

The aim of this paper is the analysis of solute transport processes in Upper Narew River based on the results of tracer experiment. Data Based Mechanistic and transient storage models were applied to Rhodamine WT tracer observations. We focus on the analysis of uncertainty and the sensitivity of model predictions to varying physical parameters, such as dispersion and channel geometry. The study...

Achieving a high quality product corresponding consumer requirements involves organizing and supporting the production process with a suitable and flexible logistics process. As the process / production flow is better organized, divided into subdomains (production, maintenance, quality), each with clearly defined indicators and responsibilities, the more the process will be more stable, easier ...

The design and planning of resilient supply chains is a major challenge due to the increasing complexity of these systems that operate in a global market and therefore are more exposed to disruptions. In the present work a design and planning model that integrates demand uncertainty is applied to five supply chain structures that are submitted to different types of disruptions. Disruptions are ...
