This paper deals with the problem of optimizing two-stage structure decision making units (DMUs) where the activity and the performance of two-stage DMU in one period effect on its efficiency in the next period. To evaluate such systems the effect of activities in one period on ones in the next term must be considered. To do so, we propose a dynamic DEA approach to measure the performance of su...

The height of the annual flood crest of the Amazon at Iquitos has increased markedly in the last decade. During this same period, there has been greatly increased deforestation in the upper parts of the Amazon watershed in Peru and Ecuador, but no significant changes in regional patterns of precipitation. The change in Amazonian water balance during the last decade appears to be the result of i...

We simulate the effect of climate change on water requirements of cold seasonwheat in various climatic zones of Iran. The research considers both observedclimate (temperature and precipitation) changes during recent decades (1960-2009)based on instrumental records and projected future changes to 2100 based on theMAGICC/SCENGEN 5.3 compound model. 20 General Circulation models are usedbased on a...

Stream ecosystems are especially vulnerable to climate warming because most aquatic organisms are ectothermic and live in dendritic networks that are easily fragmented. Many bioclimatic models predict significant range contractions in stream biotas, but subsequent biological assessments have rarely been done to determine the accuracy of these predictions. Assessments are difficult because model...

A necessary first step in the preservation of digital scientific data is gathering enough information “about” a scientific outcome or data collection, that it can be discovered and used a decade from now as easily as it is reused next week. Data provenance, or lineage of a collection, can capture how a particular scientific collection was created, when and by whom. Our goal is to devise tools a...

Prior to the 1980s, numerous charges of discrimination were noteworthy among women in Hollywood. In those years, women were in uncertain situations, so they seemed aimless and vulnerable. In the period that this article focuses on, the female characters are or have become intelligent and therefore open-minded and potentially independent. Although, they are still vulnerable and unsure of themsel...
