This study describes development of a new global reference evapotranspiration (ET0) seasonal reforecast and skill evaluation with a particular emphasis on the potential use of this dataset by FEWS NET to support food insecurity early warning. The ET0 reforecasts span the 1982–2009 period and are calculated following the American Society for Civil Engineers formulation of the Penman–Monteith method driven by seasonal climate forecasts of monthly mean temperature, humidity, wind speed, and solar radiation from the National Centers for Environmental Prediction CFSv2 model and the National Aeronautics and Space Administration GEOS-5 model. The skill evaluation, using deterministic and probabilistic scores, focuses on the December–February (DJF), March–May (MAM), June–August (JJA), and September–November seasons. The res...

Many laboratories were not able to detect the presence of CB2 cannabinoid receptors (CB2‐Rs) in healthy brains, but CB2‐R expression has been demonstrated in rat microglial cells and other brain‐associated cells during inflammation. Thus, neuronal expression of CB2‐Rs has been ambiguous and controversial, and its role in depression and substance abuse is unknown. In this study we tested the hypothesis that genetic variants of the CB2 gene might be associated with depression in a human population and that alteration in CB2 gene expression may be involved in the effects of abused substances, including opiates, cocaine, and ethanol, in rodents. Here we demonstrate that a high incidence of Q63R but not H316Y polymorphism in the CB2 gene was found in Japanese depressed subjects. CB2‐Rs and their gene transcripts are expressed in the bra...

The Refugee Adult Education Unit has a preliteracy phase, offering health and agricultural instruction; a basic literacy phase, teaching reading and writing; and a postliteracy/continuing education phase, enabling skill retention and reinforcement.
