this paper measures event risk which is introducing by the ball committee to measure the effect of sudden news. this study calculates event risk by using the data of registered firms in tehran stock market between 1993 and 1994. for computing event risk, we use daily market capitalization for 80 firms during 1993-2009, then dividing these firms to three baskets; big, medium and small. the model...

The East Greenland Rift Basin comprises a series of Jurassic subbasins with different crustal configurations, and somewhat tectonic histories styles. roughly N–S elongated basin is exposed in central northern over length more than 600 km width up to 250 km. southernmost exposures are found the largest subbasin Jameson Land, while northernmost on Store Koldewey Germania Land. focus present revis...

The Tommy Creek Domain is a complex, yet little studied, terrane in the Eastern Subprovince of Mount Isa Province, northwest Queensland Australia. In this study, we take advantage modern low-cost and rapid geochronology techniques to undertake an iterative dating approach integrated with detailed fieldwork define ages extents numerous lithologies units Domain. This includes some not previously ...
