models to the expression data for each gene but with a common value for the between-replicate correlation. The method greatly improves the precision with which the genewise variances are estimated and thereby improves inference methods designed to identify differentially expressed genes. The method may

intentions to drop out of high school, which are later implemented, leading to actual dropout behavior. This model was tested with high school students (N = 4,537) by means of a prospective design. Results from analyses of variance and a structural equation modeling analysis (with L1SREL) were found

” information models to facilitate an integrated manufacturing environment. How information models are used to define data requirements and how, in a practical application, information models enable information sharing and exchange are described. Several information modeling methodologies, modeling languages

Summary: This paper presents the model of Intelligence Information System (IIS) based on a Service-Oriented Architecture. In this paper we propose the new service’s model, based on the Intelligence cycle and other systems which are necessary for gathering intelligence information and data

Data warehousing systems enable enterprise managers to acquire and integrate information from heterogeneous sources and to query very large databases efficiently. Building a data warehouse requires adopting design and implementation techniques completely different from those underlying information

at complex multiapplication information systems using a repository to share data among applications. The framework proposes to keep a strict separation between Man-Machine-Interface and Model data, and provides design and implementation support to do this effectively. The framework and methodological

and for different kinds of situations, including the use of new information technologies as tools. This leads us to the important question, “What research methods are most helpful for creating and improving instructional design theories? ” In this chapter, we offer a detailed description of one research

domain of our eco-social system is thereby transformed. We live in a new economy, characterized by three fundamental features. First, it is informational , that is, the capacity of generating knowledge and processing/managing information determine the productivity and competitiveness of all kinds

under control the cost and the complexity of the project. Although the design phase is only a step within the overall life-cycle, the identification of a proper life-cycle model and the adoption of a correct design methodology are strictly related since each one influences the other. HISTORICAL

the design and implementation of an agile manufacturing information system integrating manufacturing databases dispersed at various partner sites. We propose a framework in which: (1) Information is modeled in a hierarchical fashion using Object Oriented Methodology (OOM). (2) Information transactions
