The paper describes unexpected problems encountered in the automation of a scheduling process using an IT application already in use in other similar organisations. A grounded theory approach was used to collect and categorise data on the case. Activity Theory was then used to analyse the attempt by management to implement organisational change through the introduction of the system. The findings suggest that it is inadvisable to impose organisational change through the introduction of a complex IT system, particularly when this disrupts entrenched decision-making processes of the organisation.

Geomagnetic Activity Forcing Of The Northern Annular Mode Via The Stratosphere, Daniel Palamara, Edward Bryant
Faculty of Science, Medicine and Health - Papers: part A
We consider various aspects of the link between solar-modulated geomagnetic activity and the Northern Annular Mode (NAM). Our results indicate that the geomagnetic forcing of atmospheric circulation in the Northern Hemisphere is temporally and seasonally restricted, modulated by the Quasi-Biennial Oscillation (QBO), and reliant on stratosphere-troposphere coupling. When the data are restricted to January values after 1965, for years in which the January QBO is eastwards, the correlation coefficient between the geomagnetic AA index and the NAM is 0.85. These results can account for many of the enigmatic features of Northern Hemisphere circulation.
