In this paper we propose an accountability management framework for resource sharing in peer-to-peer (P2P) distributed computing systems. On the basis of a generalized e-coin paradigm, we developed the management framework based on the distribution of resource credit/policy, exchange of service and service evidences, and accountability management. A tree topology is assumed for the distribution...

The spatial distribution pattern of cultural resource generally manifests clustered qualification to some extent, and we can infer the vicissitudes of the correlative culture by analyzing the changing rule of the spatial distribution pattern of cultural resource. However, the majority of the concerned researches are still at the level of qualitative statistics and thematic map visualization of ...

In order to coexist in sympatry, subordinate species must somehow obtain resources that dominant taxa may generally control. We examined the response of an ant community to fine-scale variation in resource distribution, as a mechanism enabling resource acquisition by subordinates in the presence of dominant taxa. Food (6g) was partitioned as 1, 8, or 64 items in a 0.4m 2 area, near nests of the...

The aim of a multi-mode resource-constrained project scheduling problem (MRCPSP) is to assign resource(s) with the restricted capacity to an execution mode of activities by considering relationship constraints, to achieve pre-determined objective(s). These goals vary with managers or decision makers of any organization who should determine suitable objective(s) considering organization strategi...

Resource distribution networks play a crucial role at all scales of biological and artificial systems. Within an individual organism, cells receive nutrients and expel waste. Nutrients must be transported from a source to all cells efficiently. Similarly, waste must be collected from every cell and transported out of the organism. Communities of organisms and entire ecosystems have the same req...

According to conceptual models, the distribution of resources plays a critical role in determining how organisms distribute themselves near habitat edges. These models are frequently used to achieve a mechanistic understanding of edge effects, but because they are based predominantly on correlative studies, there is need for a demonstration of causality, which is best done through experimentati...

A key feature of the NSW health system is its 17 geographically-based area health services (AHSs). Funding to the AHSs by the NSW Department of Health has been guided by the objective of providing the AHSs with a share of resources that allows the achievement of comparable access to health services, assuming the achievement of reasonable levels of efficiency. The mechanism for achieving this ob...

Following severe flooding in 2008, three Iowa communities acquired over 1000 damaged properties to support disaster recovery and mitigation. This research applies a distributive justice framework to analyze the distribution of disaster recovery funds for property acquisition. Two research questions drive the analysis: (1) how does recovery vary by acquisition funding source; and (2) what is the...
