The natural direct and indirect effects in causal mediation analysis with survival data having one mediator is addressed by VanderWeele. He derived an approach for (1) accelerated failure time regression model general cases (2) a proportional hazards when the time-to-event outcome rare. If not rare, then VanderWeele did derive simple closed-form expression log-natural because baseline cumulativ...
Background: Metal pollution is a problem in many parts of the world. These metals can be harmful when they exceed the recommended limits. By analyzing metal concentrations in living organisms, it is possible to deduce the bioavailability and the level of environmental contamination for specific metals in an ecosystem. The aim of this study was to determine the heavy metals copper, cadmium, lead...
it is very important to recognize the areas with high potential risk of landslide in order to resist that. in a case study, thirty three landslides have been observed in safarood watershed. the purpose of this study is to recognize factors and zonation of potential areas for landslide. this paper covers specific factors including lithology, fault, height, slope, direction, rainfall, soil, veget...
Abstract Small island developing States, such as those in the Pacific, are often prone to multiple hazards that have potential result disaster and / or restrict development. Hazard data can be limited resolution omitted near SIDS’ coasts, but a growing improved range of datasets becoming available. Through an analysis approximately 100 policy documents on risk management Pacific nations, we fou...
Foreword The purpose of the Delta Risk Management Strategy (DRMS) Initial Technical Framework (ITF) is to guide the analysis of specific technical topics as they relate to assessing potential risks to Delta levees and assets resulting from various potential impacts (e.g., floods, earthquakes, subsidence, and climate change). These ITFs are considered " starting points " for the work that is to ...
