Variability is true heterogeneity existing within a population that cannot be reduced or eliminated by more or better determinations. Uncertainty represents ignorance about poorly characterized phenomena, but it can be reduced by collecting more data. The aim of this paper was to study the impact of the variability and uncertainty of the main variables, i.e., emissions and meteorology, of the P...

Environmental risk assessment is typically uncertain due to different perceptions of the risk problem and limited knowledge about the physical, chemical, and biological processes underlying the risk. The present paper provides a systematic overview of the implications of different types of uncertainty for risk management, with a focus on risk-based management of river basins. Three different ty...

The organizational structure literature has long posited that increases in uncertainty should lead to organic (adaptable) structures (e.g., Burnes and Stalker, 1961). Similarly, the operations management literature has focused on the importance of flexibility as a competitive weapon (e.g., De Meyer, Nakane, Miller and Ferdows, 1989), and as a response to environmental uncertainty (Swamidass and...

In this paper the appropriate background in Mathematics and Statistics is considered in developing methods to investigate Risk Analysis problems associated with Environmental Economics uncertainty. New senses of uncertainty are introduced and a number of sources of uncertainty are discussed and presented. The causes of uncertainty are recognized helping to understand how they affect the adopted...

Dynamically adaptive systems (DASs) are intended to monitor the execution environment and then dynamically adapt their behavior in response to changing environmental conditions. The uncertainty of the execution environment is a major motivation for dynamic adaptation; it is impossible to know at development time all of the possible combinations of environmental conditions that will be encounter...

Over the centuries, local communities have shaped atypical rules to deal with the uncertainty of their environment. They have developed complex prototypes for flexible overlapping institutions and arrangements to adapt their rules and uses to their uncertain environment. Today, this indigenous way of flexibly institutionalizing access rules could provide blueprints for dealing with uncertainty ...

From a Life Cycle Assessment study of hydraulic lubricants from vegetable and mineral oil, it has been found that the agricultural step in the biodegradable hydraulic lubricant production has the main environmental impact. The aim of this study is to develop an uncertainty analysis of agricultural data used in the biodegradable hydraulic lubricant inventory from this LCA to determine the influe...

Uncertainty in the environment has implications for an organisation’s structures, strategies and processes. By extending an existing uncertainty framework and measuring how it is influenced by strategic decision-making, entrepreneurial orientation and organisation structure, this paper explores the process of environmental interpretation. Hypotheses are formulated for testing on the European ai...
