Contributions of External Forcings to Southern Annular Mode Trends

An observed trend in the Southern Hemisphere annular mode (SAM) during recent decades has involved an intensification of the polar vortex. The source of this trend is a matter of scientific debate with stratospheric ozone losses, greenhouse gas increases, and natural variability all being possible contenders. Because it is difficult to separate the contribution of various external forcings to t...

[Editorial] Business Process Re-Engineering: A Modeling Perspective

The increasing speed of technological progress has resulted in complex and dynamic business environments. As organisations need to adapt to new trading conditions and respond to competitive pressures, various change management approaches such as business process reengineering (BPR) are being adopted. This management concept relates to the fundamental rethinking and radical redesign of an entire...

[Editorial] Business Process Re-Engineering: A Design Perspective

Business Process Re-engineering (BPR) is considered by many to have ‘had its day’ with scholars such as Hansen (Foster, 1994) stating that BPR is a misnomenor, and goes onto conclude that re-engineering does not exist because business systems were never engineered in the first place, they simply developed. Yet, others such as Hales and Savoie, (1994) and Irani et al., (1997) argue that BPR is a...
