At ABC College, excessive grade innation has hindered the administration's eeorts to identify the most talented students and to rank the students in a reasonable way. We construct a method for more accurately evaluating student ability that adjusts a student's grade based on whether the professor assigning the grade tends to be unusually harsh or lenient. Since we have no real data, we construc...

PURPOSE The median survival for patients diagnosed with glioblastoma multiforme, the most common type of brain tumor, is less than 1 year. Animal glioma models that are more predictive of therapeutic response in human patients than traditional models and that are genetically and histologically accurate are an unmet need. The nestin tv-a (Ntv-a) genetically engineered mouse spontaneously develop...
