Using a Pathways approach, controversies over environmental and natural resource management are viewed as expressions of alternative, or competing, pathways to sustainability. This supports deeper understanding of the underlying causes of natural resource management controversies. The framework is composed of two elements: the STEPS (Social, Technological, and Environmental Pathways to Sustaina...

Variation in environmental or genetic quality leads to phenotypic variation in condition, but how much variation in fitness is created by this variation in condition? Using Drosophila melanogaster, we manipulated condition via alternative larval diets and then tested several key factors predicted to influence how much variation in fitness results from differences in condition. Specifically, we ...

Abstract Background Advances in fire modeling help quantify and map various components characterizations of wildfire risk furthermore evaluate the ability fuel treatments to mitigate risk. However, a need remains for guidance designing landscape-scale with protection objectives, resource management response mind. It is also important consider how human factors related tolerance may affect oppor...

due to consuming about 50%-80% of health resources, hospitals are the greatest and costly operational units in iranian health system. so allocation of resources specially human and space resources as the most expensive ones is really important for further controlling of costs, analysis of costs and making suitable policies for increasing the profitability and allocation of resources and improve...

We present an alternative algorithm of fully decentralized resource discovery in Grid computing, which enables the sharing, selection, and aggregation of a wide variety of geographically distributed computational resources. Our algorithm is based on a simply unicast request transmission that can be easily implemented. The addition of a reservation algorithm can find more available matching reso...

This paper contributes to the historical political economy literature, which considers the fiscal imperatives of the state to be amongst the driving forces behind the emergence of representative systems of government, by examining the impact on democracy of a government’s reliance on alternative sources of revenue. ‘Taxation’ and ‘natural resource rent extraction’ are considered as alternative ...

Wastewater treatment is essential to protecting the environment and human welfare. Water is a resource that is fundamental to human life, which makes taking action to protect the resource on the forefront of research. Treated wastewater effluent is a possible source that can pollute receiving water bodies and cause contamination. It is often discharged into larger bodies of water that are used ...

Many complex distributed applications require quality of service (QoS) guarantees on the end-to-end transfer of information across a distributed system. A major problem faced by any system, or infrastructure, providing QoS guarantees to such applications is that resource requirements and availability may change at run-time. Consequently, adaptive resource (and, hence, service) management mechan...
