Exploding the stability myth : structural change in the Australian trade union movement, 1969-85

Traditional studies of long-term change in trade union structure have predominantly relied upon the aggregate number of trade unions as the principal measure, or indicator of change over time. Using the Australian trade union movement as an example, this article argues that our understanding of the long-term change in the external structure of trade unions would be better served by using Waddington's structural events approach examining the incidence of four distinct 'structural events'--union formations, dissolutions, breakaways and mergers. In doing so, this article presents new data on structural change in the Australian trade union movement between 1969 and 1985. It casts doubt on the traditional argument, which relied on the apparent lack of change in the aggregate number of unions reported by the Australian Bureau of Statistics to argue that this period was one of structural rigidity. The structural events data reveals that far from being a period of structural stability, it was in fact one of significant change, albeit in the composition of the Australian trade union movement, rather than in the aggregate number of trade unions in operation.

The development of the institutional investor : the case of Australian life insurers 1945-85

This paper considers the post-war development of asset management practices among Australian life insurers, which have historically been among the largest institutional investors in Australia. A complex process of adaptation and organisational restructuring allowed life insurers to transform from basic investors of policy-holders’ funds to large multifaceted institutional investors in just three decades. Three stages in the development of investment practices are identified. These phases trace the process of expanding existing knowledge bases; diversification; and the acquisition of new skills; consolidation and the integration of these skills into institutional structures; thus completing one cycle of organisational learning and setting the stage for the next.

Improved 2D‐HPLC of red wine by incorporating pre‐process signal‐smoothing algorithms

Twomultidimensional HPLC separations of an Australian red wine are presented, >70% of the available separation space was used. A porous graphitic carbon (PGC) stationary phase was used as the first dimension in both separations with both RP core–shell and hydrophilic interaction chromatography fully porous columns used separately in the second dimension. To overcome peak analysis problems caused by signal noise and low detection limits, the data were pre-processed with penalised least-squares smoothing. The PGC × RP combination separated 85 peaks with a spreading angle of 71 and the PGC × hydrophilic interaction chromatography separated 207 peaks with a spreading angle of 80. Both 2D-HPLC steps were completed in 76 min using a comprehensive stop-and-go approach. A smoothing step was added to peak-picking processes and was able to greatly reduce the number of false peaks present due to noise in the chromatograms. The required thresholds were not able to ignore the noise because of the small magnitude of the peaks; 1874 peaks were located in the non-smoothed PGC × RP separation that reduced to 227 peaks after smoothing was included.
