this study investigates the effectiveness of the kriging interpolation model and the emission weighted proximity model (ewpm) in assessing relative exposure risk of air pollution using results from the american meteorological society/epa regulatory model (aermod) as benchmarks. we used simulated exposure risk to so2 in the dallas area in texas in this evaluation. results suggest that the relati...

This research aims to apply a model to the study and analysis of environmental and natural resource costs created in supply chains of goods and services produced in Thailand, and propose indicators for environmental problem management, caused by goods and services production, based on concepts of sustainable production and consumer behavior. The research showed that the highest environmental co...

data envelopment analysis (dea) has been long employed as a popular methodology to evaluate the performance of various production activities with multiple inputs and outputs. however, an important issue is that the production process in the real world inevitably generates undesirable outputs (like wastes and pollutants) along with desirable outputs. therefore, the undesirable outputs should be ...

This paper integrates a stakeholder perspective into the resource-based view of the firm, to analyze the mechanisms that link the adoption of the international Environmental Management Standard ISO 14001 to firms’ competitive advantage. This paper shows that the perceived competitiveness impact of the standard depends mostly on the involvement of firms’ external stakeholders (distributors, cust...

A fundamental problem that agro-environmental sciences have to face today is the lack of interdisciplinary linkages between the various disciplines dealing with agriculture and environment and the physics of the “soil medium” organization, which is the object of study of the pedology. Currently, the soil medium is far from being considered as the organized physical medium providing the physical...

We introduce an eecient and robust spatial index to support a set of diier-ent queries, which is developed from G unther's Celltree 6 and the Monotonous Bisector Tree 11;16. In practice, huge scenes are manageable by using the paging{concept. For convex polyhedrons in N{dimensional real space and any L p {metric (1 p 1) we are able to show that the C-tree can be constructed in time O(n log n), ...
