drought is a climatological hazard and is a part of the climate of a region. this climatological phenomenon has some properties that distinguish it from other natural disasters. drought is a gradual phenomenon and when the amount of moisture and precipitation become less than normal value in a certain period, its damages are non- structural in this condition and it is said that drought has occu...

The efficiency of three statistical models, AHP surface-weighted density bivariate (semi-quantitative models), stepwise multivariate regression and logistic multivariate regression models were compared in Chehel-Chai watershed in Golestan province, Iran. In current study the hazard map was prepared according to the top model of landslide hazard map. Chehel-Chai watershed is located as one of Go...

background: although the cox proportional hazard regression is the most popular model for analyzing the prognostic factors on survival of cancer patients, under certain circumstances, parametric models estimate the parameter more efficiently than the cox model.  the aim of this study was to compare the cox regression model  with parametric models in patients with gastric cancer who registered a...

This paper considers a simple model of credit cycles driven by moral hazard in financial intermediation. Financial agents or bankers must earn moral-hazard rents, but the cost of these rents can be efficiently spread over an agent's entire career, by promising large late-career rewards if the agent has a consistently successful record. Dynamic interactions among different generations of financi...

A physics-based statistical stochastic system is developed for estimating the long-term hazard of rare, high impact landfall events globally from ensembles of synthetic tropical cyclones. There are three components representing the complete storm lifetime: an index-based genesis model, a beta-advection track model and an autoregressive intensity model. All three components depend upon the local...

urbanization is a pervasive global trend. the development of residential areas and road network in hajighoshan watershed (northern iran) has been observed in the recent several decades. the objective of this study is the quantitative investigation of the effects of impervious surfaces development and urban development on runoff generation and flood hazard. the study of urban area development wa...

We performed a follow-up study to address whether high sensitivity C-reactive protein (hs-CRP) levels within the normal range can predict the development of non-alcoholic fatty liver disease (NAFLD) in healthy male subjects. Among15347 male workers between 30 and 59 years old who received annual health check-ups in 2002, a NAFLD-free cohort of 4,138 was followed through December 2009. Alcohol c...

The Controllability Principle in Responsibility Accounting: Another Look In this paper, we illustrate some subtleties in responsibility accounting by studying settings in which there is an interplay between different control problems. In a setting in which agents are involved in both team and individual production, we provide conditions under which the agents are not held responsible for the te...
