Research studies frequently yield conflicting results. Resolving these conflicts is a grand challenge to effective application of research results. This paper presents a new framework for encapsulating the context and findings of research studies into a dimensional knowledge base which makes it easy to identify the conflicting results, and to explore the differences in context that might explai...

Information systems (IS) strategic planners debate what is the most appropriate data warehouse (DW) topology for an organization. The primary question is whether to start DW projects with enterprise-wide data warehouses (EDWs) or with smaller-scale data marts (DMs). This article examines the relationship between modes of IT governance and DW topology to determine whether or not the implementati...

The term refers to the ability of combining the content of two or more heterogeneous data warehouses, for the purpose of cross-analysis. This need emerges in a variety of practical situations. For instance, when different designers of a large company develop their data marts independently, or when different organizations involved in the same project need to integrate their data warehouses. Data...

The last decade has seen a deluge in data collection and dissemination across a broad range of areas. This phenomena has led to creation of online data markets where entities engage in sale and purchase of data. In this scenario, the key challenge for the data market platform is to ensure that it allows real time, scalable, arbitrage-free pricing of user queries. At the same time, the platform ...

Uveal melanoma (UM) is the most common primary intraocular malignancy and the leading potentially fatal primary intraocular disease in adults. Melanoma antigen recognized by T-cells (MART-1) has been studied extensively as a clinically important diagnostic marker for melanoma, however, its biological function remains unclear. In the present study, the UM cell line SP6.5, which showed a high lev...

Despite considerable debate as to Wal-Mart’s impact on retail workers, to date there has been little structural analysis on the topic. This paper measures and tests for Wal-Mart’s monopsony power in local labor markets using a dominant-firm model and data on contiguous U.S. counties where the company operates. Empirical results show that Wal-Mart’s monopsony power over workers varies significan...

Abc-boost is a new line of boosting algorithms for multi-class classification, by utilizing the commonly used sum-to-zero constraint. To implement abc-boost, a base class must be identified at each boosting step. Prior studies used a very expensive procedure based on exhaustive search for determining the base class at each boosting step. Good testing performance of abc-boost (implemented as abc...
