The present study investigated factors affecting risk management by women rice farmers in the township of Sari in Iran. The statistical population comprised 1677 women who cultivate rice in Sari; 248 women were selected for the study using stratified random sampling. The data was analyzed using descriptive and inferential statistics with SPSSWin16 software. The Chronbach’s alpha was 0.84 and th...

This site report describes the HIRLAM project, which deals with the development and maintenance of a state-of-the-art operational numerical short-range weather forecasting system. The report provides an insight into the diierent components of these systems, presents examples what can be achieved, and describes brieey what kind of CSE research is carried out. The international project: Its aim a...

Air traffic delays in the U.S. are problematic and often attributable to convective (thunderstorms) weather. Air traffic management is complex, dynamic, and influenced by many factors such as projected high volume of departures and uncertain forecast convective weather at airports and in the airspace. To support the complexities of making a re-route decision, which is one solution to mitigate a...

The two objectives of this project were to develop an understanding of the challenges and opportunities of the supply chain of a family of currently marketed products manufactured overseas and distributed/sold worldwide and to increase the agility of the supply chain while achieving a target service level of 99% and maintaining or decreasing costs. A model was created to explore the current sup...

We explain that revisions to successive density forecasts of the same outcome, as measured by the Kullback-Leibler Information Criterion, need not be unpredictable, unlike those to conditional mean forecasts, even when the forecaster uses information efficiently. However one can still test the efficiency of fixed-event conditional density forecasts, similarly to conditional mean forecasts, by t...

In the paper a model to predict the concentrations of particulate matter PM10, PM2.5, SO2, NO, CO and O3 for a chosen number of hours forward is proposed. The method requires historical data for a large number of points in time, particularly weather forecast data, actual weather data and pollution data. The idea is that by matching forecast data with similar forecast data in the historical data...

We study the effect of downstream competition on incentives for demand forecast investments in supply chains. We show that with common pricing schemes, such as wholesale price or two-part tariffs, downstream firms under Cournot competition overinvest in demand forecasting. Analyzing the determinants of overinvestment, we demonstrate that under wholesale price contracts and two-part tariffs, tot...
