In this paper, we investigate the informational content of citation-based research evaluations. To illustrate our analysis we refer to the 2005 Handelsblatt ranking of German academic economists. We make extensive use of the recently developed Hirsch-index and relate citation incidence to...

South Africa is regarded as a leading developing country in terms of SEA practice. However, the lack of empirical research to evaluate and learn from this wealth of practical experience can be considered a major lost opportunity not only for South Africa but also for the development of our...

Plant managers generally have no direct marketing responsibilities but they have control over product quality and customer service. This paper hypothesises that many firms evaluate these managers on profit because sales, a component of profit, convey information on a plant manager's performance...

This study proposes a Continuous Auditing Assistance System (CAAS), which can assist auditors to assess potential weaknesses in the information systems. Auditors can perform auditing tasks independently, give feedback immediately on the extraordinariness and reach the objectives of continuous...

In this paper, a polling model with finite queues to analyse a production system that is operating under a pull-type control mechanism is studied. The polling model is analysed under three well-known service policies namely, exhaustive, gated and g-limited. These policies determine when and how...

Purpose – Interactive information retrieval (IR) involves many human cognitive shifts at different information behaviour levels. Cognitive science defines a cognitive shift or shift in cognitive focus as triggered by the brain's response and change due to some external force. This paper aims...

We develop a model of a failure-prone, bufferless, paced, automatic transfer line in which material flows through a number of workstations in series, receiving continuous processing along each workstation. When a workstation fails, it stops operating, and so do all the other workstations...

In this paper we show that hedge fund returns may suffer from excess smoothness, positive kurtosis and negative skewness. We argue that these distribution properties cause standard mean-variance statistics to underestimate the true variability and beta, and overrate the true performance. We...
