the concept of decision making, factors influencing it and the related outcomes have always attracted researchers. the purpose of this study is to investigate the effect of sacred values on decision making, decision difficulty and the resulting negative emotions. thus, a sample of 288 students from the university of guilan were chosen as subjects and were required to complete a standard questio...

Addressing environmental management problems at catchment scales requires an integrated modelling approach, in which key bio-physical and socio-economic drivers, processes and impacts are all considered. Development of Decision Support Systems (DSSs) for environmental management is rapidly progressing. This paper describes the integration of physical, ecological, and socio-economic components i...

Different structures may compete during development for a shared and limited pool of resources to sustain growth and differentiation. The resulting resource allocation trade-offs have the potential to alter both ontogenetic outcomes and evolutionary trajectories. However, little is known about the evolutionary causes and consequences of resource allocation trade-offs in natural populations. Her...

Most plant-feeding insects are ecological specialists restricted to one or a few closely related host-plant species. A long-standing hypothesis asserts that natural selection favors host specialization because of trade-offs between performance on alternative hosts, yet empirical evidence for such tradeoffs is scarce. Here we assess trade-offs between adaptations to alternative hosts over macroe...

Most of the search literature considers univariate alternatives even though real-world alternatives are typically characterized by multiple attributes. We address this gap by developing a model of search for multiattribute alternatives, focusing on the case of parallel search. The univariate model of parallel search has been applied to vendor selection, new product development, and innovation t...
