This paper constructs a model economy to explain how uncertainty shocks can cause business cycle fluctuations. In the model, during times of high uncertainty, the representative agent, due to risk aversion motives, moves resources from a high risk/high return production process to a low risk/low return production process. High uncertainty thus causes the firm level technology frontier to endoge...

Considering the increased complexity of energy projects as companies are entering a new technological era marking the end of "easy oil", there is a growing concern about the real preparedness of companies to deal with the new risks they are facing. The potential severity of those risks due to the important damages caused to the environment and their possible impact on populations of India. Furt...

A comparative fact can be presented in two ways. ‘Among white evangelical Christians, Obama had 40% fewer votes than McCain.’ or ‘Among white evangelical Christians, McCain had 40% more votes than Obama.’ Focusing on why Obama had fewer votes than McCain may result in a different explanation from focusing on why McCain had more votes than Obama, although it is the same fact. Thus what determine...

To compute the stability of underground engineering, a constitutive model of surrounding rock must be identified. Many constitutive models for rock mass have been proposed. In this model identification study, a generalized constitutive law for an elastic-plastic constitutive model is applied. Using the generalized constitutive law, the problem of model identification is transformed to a problem...

The benefits of radio frequency identification (RFID) technology in the supply chain are fairly compelling. It has the potential to revolutionise the efficiency, accuracy and security of the supply chain with significant impact on overall profitability. A number of companies are actively involved in testing and adopting this technology. It is estimated that the market for RFID products and serv...

In agriculture, it is required to establish and integrate food traceability systems and risk management systems in order to improve food safety in the entire food chain. The integrated traceability system for agricultural products was developed, based on innovative technology of RFID and mobile computing. In order to identify individual products on the distribution process efficiently, small RF...

Numerous studies on the distribution of building dangers have been conducted during last few decades. Even though current study gives significant insights into matter, construction industry members are nonetheless concerned about risks contracting. A product was developed to help contracting parties identify, quantify, and assign each risk address this issue. To supplement model worksheets, flo...

Present study was undertaken to examine the extent of Polycyclic Aromatic Hydrocarbons (PAHs) contamination in neighbourhood lithospheric environment of landfill site situated in eastern outer edge of Kolkata metropolitan city in West Bengal, India, along with its sources identification, spatial distribution and probabilistic cancer risks to residents. The collection and analytical tests were p...

Identification and analysis of farmers’ vulnerability associated with their risk aversion degree is one of the necessary requirements for planning and reducing impacts of drought in Iran. So, this study was investigated three risk vulnerability parameters (economic, social and technical) among wheat farmers categorized in accordance with their risk aversion degree in the Mashhad County (Iran) b...
