Risk identification, impact assessment, and response planning constitute three building blocks of project risk management. Correspondingly, three types of interactions could be envisioned between risks, between impacts of several risks on a portfolio component, and between several responses. While the interdependency of risks is a well-recognized issue, the other two types of interactions remai...

The importance of ‘‘broader” economic effects of transportation infrastructure has recently become apparent. ‘‘Broader” refers to impacts beyond the geographic boundaries within which the infrastructure investments are undertaken. Approaches to estimate ‘‘broader” impacts in production and cost function models are evaluated. A contribution of this paper is the empirical demonstration with a cro...

this study evaluates changes in species composition, catch, and cpue of three species of kilkas in the caspian sea from 1961 to 2009. the effects of fluctuations in sea level rise and fall on the catch of kilka as well as the impacts of a recent invasion by mnemiopsis leidyi (ctenophora) were assessed in terms of species composition and cpue of kilkas in the iranian coastal region of the caspia...

We use a spatially explicit biogeochemical end-to-end ecosystem model, Atlantis, to simulate impacts from the Deepwater Horizon oil spill and subsequent recovery of fish guilds. Dose-response relationships with expected oil concentrations were utilized to estimate the impact on fish growth and mortality rates. We also examine the effects of fisheries closures and impacts on recruitment. We vali...

Cumulative effects are the combined effects of multiple activities, and watershed effects are those which involve processes of water transport. Almost all impacts are influenced by multiple activities, so almost all impacts must be evaluated as cumulative impacts rather than as individual impacts. Existing definitions suggest that to be significant, an impact must be reasonably expected to have...

Workers who experience involuntary job loss suffer from deep and persistent negative consequences. In this paper, we first summarise the evidence on effects of displaced workers’ wellbeing. We conclude that displacement harms mental health economic security in short term negatively affects their earnings mortality risk long term. then extrapolate estimates Hyslop Townsend (2017) to estimate eco...

A comprehensive assessment of drought environmental and socio-economic impacts provides critical information to rational decisions supporting drought mitigation policies and programs. The objectives of this study were to survey environmental and socio-economic impacts of drought in Guilan Province, and prioritize them from the viewpoint of paddy farmers. This study was a descriptive-correlation...

This study examines the role of foreign direct investment (FDI) on growth, making a comparison between selected countries of Africa and Asia. We utilized data for 30 countries 2009. The Hausman among OLS, fixed effect and random effect models. First, aggregate data and later disaggregated the data in assess the regional impact of FDI on ec that FDI has positive relationship with GDP growth also...
