This paper describes a numerical approximation scheme for the one‐dimensional Streeter‐Phelps equations of river self‐purification. Our formulation of the problem includes second order kinetics in a coordinate system moving with the river thus analytically accounting for convection. These equations are linearized by using fractional time steps. The effects of reaeration and deoxygenation are accommodated by exponential fitting. The discrete equations are then marched forward in time using the hopscotch scheme which is explicit yet unconditionally stable (albeit conditionally consistent). Numerical examples both with and without dispersion are presented which indicate that the proposed method is much more efficient than a brute force numerical approach. Specifically, the proposed explicit scheme is amenable to parallel implementation.

The purpose of this paper is to demonstrate that there is not just a single project portfolio operating within an organisation, but instead there are multiple portfolios.

This paper follows a case study methodology, utilising secondary sources in the form of publically available reports.

The authors offer a definition of whole of enterprise portfolio management and suggest that this conceptual tool will allow an organisation to control programs and portfolios, particularly, where organizations adapt to emergent situations.

This paper is supported through a single case study using secondary data only. Whilst this provides an illustrated example to support a theoretical model, further empirical research is required to determine its applicability in other sectors and organisational contexts.

This paper provides a whole of enterprise portfolio model in the utilities sector and can be applied to many organisations. It also provides a basis for further research.

This paper provides a new perspective on portfolio management, suggesting that the organisation consists of many portfolios that need to be managed in an integrative manner, rather than just the project portfolio be examined and managed in isolation.

Looks at the 2000 Employment Research Unit Annual Conference held at the University of Cardiff in Wales on 6/7 September 2000. Spotlights the 76 or so presentations within and shows that these are in many, differing, areas across management research from: retail finance; precarious jobs and decisions; methodological lessons from feminism; call centre experience and disability discrimination. These and all points east and west are covered and laid out in a simple, abstract style, including, where applicable, references, endnotes and bibliography in an easy‐to‐follow manner. Summarizes each paper and also gives conclusions where needed, in a comfortable modern format.

The concept of a knowledge interface for library users is developed as an extension of intelligent knowledge‐base system (IKBS) concepts. Contemporary directions in intelligent decision support, particularly in the role of search intermediaries, are then examined to identify the significance of intelligent intermediaries as a solution to unstructured decision support requirements of library users. A DISCOURSE SCRIPT is given to illustrate one form of intelligent intermediary.

The purpose of this paper is to examine the challenges faced by an Australian accounting academic, R. J. Chambers, in the 1950s, in breaking into the accounting research community, at that time, almost entirely located in the USA and the UK. For academics outside the networks of accounting research publication in these countries, there were significant, but not insurmountable obstacles to conducting and publishing accounting research. We examine how these obstacles could be overcome, using the notion of “trials of strength” to trace the efforts of Chambers in wrestling with intellectual issues arising from post-war inflation, acquiring accounting literature from abroad and publishing his endeavours.

The article uses actor-network theory to provide an analytical structure for a “counter-narrative” history firmly grounded in the archives.

Documents from the R. J. Chambers Archive at the University of Sydney form the empirical basis for a narrative that portrays accounting research as a diverse process driven as much by circumstances – such as geographical location, access to accounting literature and personal connections – as the merits of the intellectual arguments.

Although the historical details are specific to the case being studied, the article provides insights into the challenges faced by researchers on the outside of international research networks in achieving recognition and in participating in academic debates.

The findings of this article can provide guidance and inspiration to accounting researchers attempting to participate in wider academic communities.

The article uses documents from perhaps the most extensive archive relating to an individual accounting academic. It examines the process of academic research in accounting in terms of the material context in which such research takes place, whereas most discussions have focussed on the underlying ideas and concepts, abstracted from the context in which they emerge.
