Data warehouses are information repositories specialized in supporting decision making. Since the decisional process typically requires an analysis of historical trends, time and its management acquire a huge importance. In this paper we consider the variety of issues, often grouped under term temporal data warehousing, implied by the need for accurately describing how information changes over ...

Antitrust has much more typically focused on the market power of sellers rather than buyers. Recent decades, however, have witnessed the rise of very large buyers in previously more fragmented industries, such as retailing, farming, ranching, natural resource extraction, and health care. The purchasing clout demonstrated by these large buyers, in turn, may enhance the advantage they have vis-à-...

Wal-Mart is a giant in the grocery industry and its influence is growing at a rapid pace. Despite Wal-Mart’s success with Everyday Low Pricing (EDLP), there is little to no evidence to suggest that other supermarket chains wish to follow a similar path. Why? This research addresses this question.

Ten years have passed since Wal-Mart’s public announcement about its RFID technology adoption plan in 2003. There has been a slowdown of RFID technology adoption since 2008. Many U.S. retailers do not consider adopting the RFID technology because of the uncertainty of return on investment and the lack of business cases. This paper evaluates labor productivity of RFID adopted retailers. This pap...

The design of cyber-physical systems (CPS) is a promising domain, where the data market is expected to soon penetrate. When engineers focus on only a particular part of data (whether intentionally or not) for establishing a design hypothesis, the design hypothesis may also be supported by data sets in the market. Therefore, the validity of such a design hypothesis cannot be evaluated by the dat...

The data, which is widely used for ecommerce applications, in decision-making processes is stored in the XML format. Thus, as more organizations view the web as an integral part of their communication and business, the importance of integrating XML data in data warehousing environments is becoming increasingly high. In this paper we show how the design of a data mart can be carried out starting...

The tumor-associated-Ag MART-1 is expressed by most human melanomas. The genes encoding an alphabeta TCR from a MART-1-specific, HLA-A2-restricted, human T cell clone have been efficiently transferred and expressed in human PBL. These retrovirally transduced PBL cultures were MART-1 peptide reactive, and most cultures recognized HLA-A2+ melanoma lines. Limiting dilution clones were generated fr...
