Self-signaling models predict less selfish behavior in a probabilistic giving setting as individuals are expected to invest pro-social identity. However, there is also substantial evidence that people tend exploit situational excuses for choices (for instance, uncertainty) and behave more selfishly. We contrast these two motivations (identity management self-deception) experimentally order test...

Multi-ring basins represent some of the largest, oldest, rarest and, therefore, least understood impact crater structures. Various theories have been put forward to explain their formation; there is currently, however, no consensus. Here, numerical modeling is used to investigate the onset of multi-ring basin formation on the Moon using two thermal profiles suitable for the lunar basin-forming ...

Benson, L.V. and Leach, D.L., 1979. Uranium transport in the Walker River Basin, California and Nevada. J. Geochem. Explor., 11: 227-248. During the summer of 1976 waters from tributaries, rivers, springs and wells were sampled in the Walker River Basin. Snow and sediments from selected sites were also sampled. All samples were analyzed for uranium and other elements. The resulting data provide...

Soil conservation and control of erosion is a basic problem in all countries. The goal of this research is to estimate erosion and sediment yield in Ekbatan Dam drainage basin by Erosion Potential Method (EPM), using Geographic Information System (GIS). The basin is located in Hamedan Province, west of Iran, in a cold and semi- arid region, with an average annual rainfall of 334mm. The study ar...
