Introduction Once a facility meets data quality standards and is approved for production, an assumption is made that the quality of data received remains at the same level. When looking at production data quality reports from various states generated using a SAS data quality program, a need for production data quality assessment was identified. By implementing a periodic data quality update on ...

A worldwide computing model, embracing a global data and computation infrastructure, is emerging to answer the LHC computing challenges. A significant fraction of the ATLAS Data Challenge 1 (DC1) was performed in a Grid environment. For efficiency of the large production tasks distributed worldwide, it is essential to provide shared production management tools comprised of integratable and inte...

The ratio estimator of the markup is output elasticity for a flexible input to that input’s cost share in total revenue. We highlight identification and estimation issues pertaining this estimator, when firm-level prices are not observed. If revenue used place elasticity, then profit maximization implies identically equal one, thus uninformative about markups. Concerning elasticities: with only...

Recent research in information quality management concluded that firms must manage information as a product, and that the entire information manufacturing system must be managed in order to enable firms to assure delivery of information products with high quality. In this paper, we report a longitudinal case study in a major hospital on how data production maps are developed and used to improve...
