Desert pavement is a distinctive feature widespread across arid lands of the world. It plays a dynamic role in geomorphic, hydrologic, and ecologic processes. Where desert pavement predominates, infiltration is limited and rainfall is delivered as runoff to nearby bare ground areas where shrubs cluster. Desert pavement surfaces may appear monotonously flat and barren, but we have found, instead...

Soil erosion is a growing challenge for agricultural production in Northern China. To explore the effect of variation in stubble height and mulching biomass on soil erosion caused by wind, we conducted a field experiment using a quadratic rotation combination design. Results showed that the quantity of straw mulch was the dominant factor affecting soil erosion, and stubble height was of seconda...

The natural environment affects the construction of desert highways. Conversely, highway construction affects the natural environment and puts the ecological environment at a disadvantage. To satisfy the variety and hierarchy of desert highway construction and discover the spatio-temporal distribution of the natural environment and its effect on highway construction engineering, an assessment o...

Catchment area and watershed delineation is a common task in hydrology. The determination of the catchment is still as a challenge considered being crucial key issues particular in flat terrains. Three concepts could be briefly identified through: the manual delineation of a catchment based on a topographic map with contour lines which is a difficult task for flat terrains, by combination of fi...

In the week before the 2003 American attack on Iraq, the effects of authoritarianism and the social dominance orientation on support for the attack were examined. Based on prior research on the nature of these constructs, a structural model was developed and tested. As predicted, authoritarianism strengthened support for the attack by intensifying the perception that Iraq threatened America. So...

We describe the Iraq Body Count Corpus (IBC-C) dataset, the first substantial armed conflict-related dataset which can be used for conflict analysis. IBCC provides a ground-truth dataset for conflict specific named entity recognition, slot filling, and event de-duplication. IBCC is constructed using data collected by the Iraq Body Count project which has been recording incidents from the ongoin...

Recently Cabrol et al. (2014), hereafter C14, reported measurements of the UV Index (UVI) reaching 43.3 at a high altitude location in the Andes (Licancabur; 22.5◦ S, 67.5◦ W, 5917m a.s.l.). This value is much larger than those previously reported from other high altitude tropical locations. For example, UVI maxima reported for Mauna Loa (19.5◦ N, 155.6◦ W, 3397m a.s.l.) (Bodhaine et al., 1997;...
