Proposed Framework which Uses Object Oriented Principles in Relational Systems: Structure and Formating (Part 2)

STRIMBEI, CÄƒtÄƒlin - In: Informatica Economica X (2006) 2, pp. 11-16

Our approach tries to overcome the limitations of so called â€œflat natureâ€ of relational systems, in the actual context of actual relational database theories, database systems technologies and object oriented methodologies by proposing an MDA framework to map an object oriented (UML...

Detecting Clusters in the Data from Variance Decompositions of Its Projections

Yatracos, Yannis - In: Journal of Classification 30 (2013) 1, pp. 30-55

A new projection-pursuit index is used to identify clusters and other structures in multivariate data. It is obtained from the variance decompositions of the data’s one-dimensional projections, without assuming a model for the data or that the number of clusters is known. The index is affine...

Constituents and their expectation : towards a critical-pragmatic theory of information systems project management

Brook, Phillip W. J. - University of Western Sydney; College of Law and Business; … - 2004

This dissertation presents a theoretical model of information systems (IS) project management that aims to improve the rate of project success, estimated at time of writing to be less than 50% despite over thirty years of experience. The inquiry into IS managementand the development of the CED...

A new constrained stochastic multidimensional scaling vector model : An application to the perceived importance of leadership attributes

Scott, Crystal J.; DeSarbo, Wayne S. - In: Journal of Modelling in Management 6 (2011) 1, pp. 7-32

Purpose – Multidimensional scaling (MDS) represents a family of various geometric models for the multidimensional representation of the structure in data as well as the corresponding set of methods for fitting such spatial models. Its major uses in business include positioning, market...

Protocols for automated negotiations with buyer anonymity and seller reputations

Cranor, Lorrie Faith; Resnick, Paul - 2000

In many Internet commerce applications buyers can easily achieve anonymity, limiting what a seller can learn about any buyer individually. However, because sellers need to keep a fixed web address, buyers can probe them repeatedly or pool their information about sellers with the information...
