Purpose – The purpose of this paper is to enable construction project team members to understand the factors that they must closely monitor to complete projects with a desired quality and also to predict quality performance during the course of a project. With quality being one of the prime...

Purpose – The aim of this paper is to explore the possibility of retrieving information with Kohonen self‐organising maps, which are known to be effective to group objects according to their similarity or dissimilarity. Design/methodology/approach – After conventional preprocessing, such...

Purpose – The purpose of this paper is to compare the performance of neural networks (NNs) and support vector machines (SVMs) as text classifiers. SVMs are considered one of the best classifiers. NNs could be adopted as text classifiers if their performance is comparable to that of SVMs....

Since 1975, an increase in the return to skill (measured by years of education), in the percentage of the labor force that is skilled, and in the variance of wage income within skill categories have characterized the U.S. labor market. While the first two facts point towards an increase in the...

Purpose – The purpose of this paper is to propose predictive models of speculative revaluation attacks, which would facilitate currency risk hedging in emerging and developed countries. Design/methodology/approach – The purpose of this paper is achieved using the methodology of multiple...

Purpose – The objective of this paper is to stress the importance of detecting financial frauds in predicting business failures disclosed by the unexpected financial crisis brought by Enron, Worldcom and other corporate distresses involving accounting irregularities....

Purpose – The purpose of this paper is to assess next hour load forecast in medium voltage electricity distribution. Design/methodology/approach – The methodological approach used in this paper, is based on a regressive method – artificial neural network. A real life case study is used for...

Purpose – The purpose of this paper is to critically analyze whether supply networks may be validly treated as complex adaptive systems (CAS). Finding this to be true, the paper turns into the latest concerns of complexity science like Pareto distributions to explain well‐known phenomena of...
