development projects in natural water resources like rivers and lakes, specially transferring water to use in agriculture, domestic and industrial sector without considering environmental values, causes irrecoverable and irreversible damage to ecosystem and future options. if we consider the future generation and species rights, those damages and costs can be very much than we take in. the abov...

this study aimed at identifying components of the household health costs.this study was a qualitative research conducted in two main phases. the first phase consisted of interviews with sample households selected in eight provinces of iran. they were to identify components of the household health costs. in the second phase, components were determined as direct, indirect and intangible based on ...

From a societal perspective, it is desirable for all transportation users to pay their full social (private and external) costs. We estimate four general types of external costs for intercity freight trucking and compare them with the private costs incurred by carriers. Estimated external costs include: accidents (fatalities, injuries, and property damage); emissions (air pollution and greenhou...

Fruit loss to birds is a long-standing and costly problem for many producers. We conducted a survey of Honeycrisp apple, blueberry, cherry, and wine grape growers in California, Michigan, New York, Oregon, and Washington to estimate costs of bird damage and benefits of bird damage management. We also assessed grower perceptions of impacts on profits and effectiveness of bird management techniqu...

Increased incidence of food-borne illnesses is a matter of significant concern for the community and the government alike. An outbreak of E. coli O111 that occurred in Australia in 1995 affected 200 people of whom 22 developed HUS while one person died. This study analyses the economic costs of the outbreak. The total cost of the outbreak is estimated to be A$5. 61 million. Productivity loss re...

Introduction: Due to occupational accidents, many costs are annually lost from the countries’ Gross Domestic Product (GDP). Estimating these costs can be essential for optimal investments and establishing appropriate policies in many countries, such as Iran. The present study aimed to review the studies conducted on the safety economics and the costs of accidents in Iran from 2000 to 2021. Mat...

Earthquakes are among those natural hazards which may lead to disruption in the function of arterial traffic routes. Road networks are particularly vulnerable, due to their geographical dispersion, extensive functions and structural reliance on favourable geophysical conditions. Traffic functionality after a natural disaster and the repair/rehabilitation cost of roads are crucial considerations...

This paper presents a new method for detecting beam and frame damage caused by an earthquake. Despite comprehensive investigations on structural damage detection, which mostly have focused on damage detection of elastic structures, the present study deals with nonlinear damage detection in structures. Furthermore, in the proposed method, only measurements of the damaged structures during an ear...

road traffic accidents and the effects they subsequently incur are increasing dramatically, and estimating the cost of road traffic crashes could be a vital step in improving the recognition of this widespread problem. the main objective of this paper is to estimate the cost of road traffic crashes in iran using the human capital (hc) method. results of this study indicate that the cost of road...
