Land degradation is a global problem that particularly impacts the poor rural inhabitants of low and middle-income countries. We improve upon existing literature by estimating the extent of rural populations in 2000 and 2010 globally on degrading and improving agricultural land, taking into account the role of market access, and analyzing the resulting impacts on poverty. Using a variety of spa...

OBJECTIVE To investigate the feasibility, costs and sample representativeness of a recruitment method that used workers with back injuries as the point of entry into diverse working environments. METHODS Workers' compensation claims were used to randomly sample workers from five heavy industries and to recruit their employers for ergonomic assessments of the injured worker and up to 2 co-work...

Psychologists have consistently documented people’s tendency to be overconfident about their own ability. We interpret workers’ confidence in their own skills as their morale, and investigate the implication of worker overconfidence on the firm’s optimal wage-setting policies. In our model, a wage contract both provides incentives and conveys to the worker the firm’s opinion about her ability, ...

Land surface radiation and energy budgets are critical to address a variety of scientific and application issues related to climate trends, weather predictions, hydrologic and biogeophysical modeling, and the monitoring of ecosystem health and agricultural crops. This is an introductory paper to the special issue of land surface radiation and energy budgets from an international conference on t...

Prior Converted Croplands (PCCs) are historic wetlands that were transformed (drained, dredged, filled or leveled) to support production of agricultural crops prior to “Swampbuster” provisions of the 1985 Food Security Act. Our research suggests that PCCs can substantially reduce nitrate export from agricultural watersheds in the region, an ecosystem function shared with natural and restored we...

With this presentation, my role is to help to stir the discussion. Perhaps it will open the dialogue so that we have a sense of where we have been, where we are, and then what’s ahead. Figure shows a photograph from 986, and in Figure is a photograph taken two years later. We developed a tomato phenotype—viral coat-protein-mediated resistance to a common disease of tomato—with a technology that...

The geographical variation in Helicobacter pylori genotypes is an observed phenomenon. Cytotoxin associated genes A (cagA) and E (cagE), and vacuolating cytotoxin (vacA) genotypes of H. pylori are associated with peptic ulcer disease (PUD). This study compared the distribution of these genotypes in Iranian and Afghani isolates and their association with clinical outcomes. H. pylori infected pat...

OBJECTIVE The aim of the present study was to develop reference data for the Iranian population for anthropometric values and cardiometabolic data in comparison with those in Americans, as representative of a Western population. DESIGN The present cross-sectional survey, conducted as part of the baseline survey of a community-based interventional study (the Isfahan Healthy Heart Programme), u...
