The salience of market, bureaucratic, and clan controls in the management of family firm transitions: some tentative Australian evidence

Despite the numerical and economic significance of family businesses to Australia, they are not extensively researched. This paper reports some of the results from a nationwide study of Australian family-owned businesses that sought to ascertain and understand their management and control practices. In particular, the paper assesses the organizational transitions of Australian family firms in terms of their dominant control practices. These control measures are evaluated according to Ouchi's classification of market, bureaucratic, and clan controls. The salience of these different forms of control serves to identify distinctive patterns that define periods of organizational passage (life cycles)

Epidermal growth factor receptors in the oesophagus.

The quantity and distribution of epidermal growth factor receptors (EGF-R) in oesophageal mucosa was studied in the oesophagus in order to determine its role in oesophageal disease. Fifty five biopsies were taken from different levels of the oesophagus in 25 consecutive patients undergoing endoscopy. Another group of eight patients with histologically proven Barrett's oesophagitis had a biopsy taken from the area of columnar lined oesophagus. A peripheral, membranous pattern was seen predominantly confined to the basal and immediately suprabasal cells in all of the first group of patients. In the superficial cells a few granular cytoplasmic structures were positive. All patients with Barrett's oesophagitis showed EGF-R staining of the surface epithelium. A computerised planimeter was used to determine the proportion of stained areas of squamous cells which were expressed as a percentage of the total area of squamous cells. The difference in the area of cells stained for EGF-R between normal and inflamed oesophageal mucosa (29.5% and 43.1% respectively) was significant (p less than 0.001)
