Corporate Social Responsibility at African mines: Linking the past to the present.

This paper traces the origins of the 'brand' of Corporate Social Responsibility (CSR) employed at large-scale mines across sub-Saharan Africa. Conceived within fortified resource enclaves, the policies adopted and actions taken in the area of CSR at many of the region's large-scale mines today have had had minimal effect on community wellbeing. Further examination reveals that contemporary CSR strategy in the region's mining sector is often a 'repackaging' and 'rebranding' of moves made by major operators during the colonial period and early years of country independence to pacify and engage local communities.

Validation and impact of a new technique for assessment of glomerular filtration rate in patients with liver disease.

Objectives: Previously we have proposed a technique for the measurement of plasma clearance in patients with ascites. The impact of using the technique was assessed and the results compared with those from a reference technique in 111 patients having glomerular filtration rate measurements as part of their workup for liver transplantation.

Methods: Results of calculations using the new technique were compared with plasma clearance measurements obtained using a conventional slope-intercept technique and with clearance measurements based on urine collection.
