Multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. One of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...

background: dental fear leads to lack of child cooperation. in general, without the patient's cooperation, success in remedy is impossible. this study aimed to evaluate parental view about the origins of the dental fear in children as well as their view about factors contributing to the prevention of child dental fear. methods: this was a cross sectional descriptive and analytical study which w...

T he units that are subject to selection pressure in evolutionary biology are ‘‘strategies,’’ which are conditional actions (for example, do P if X occurs; otherwise do Q). In contrast, the units in economics (they are called ‘‘people’’) select strategies from available menus so as to further their projects and purposes. If evolutionary dynamics involves mindless competition among strategies, e...

J. Doyne Farmer & John Geanakoplos Assessing the relative value of a benefit (or harm) in the future vs. the present is a fundamental problem in economics1. The conventional approach is to discount the future exponentially. This can be motivated by the opportunity cost relative to an investment paying fixed interest2. In contrast, real interest rates vary randomly, so the resulting effective di...

Implementation of adaptation actions to protect biodiversity is limited by uncertainty about the future. One reason for this is the fear of making the wrong decisions caused by the myriad future scenarios presented to decision-makers. We propose an adaptive management (AM) method for optimally managing a population under uncertain and changing habitat conditions. Our approach incorporates multi...

Parliamentary libraries serve parliamentary institutions on a national or local level. Usually they are founded at the same time as the parliament itself and organized according to the parliamentary model of the country in which they are located. The parliamentary library’s mission is to support and facilitate parliamentary activities and make available all useful sources of information to the ...
