Farming for Walmart: the politics of corporate control and responsibility in the global South

To analyse corporate social responsibility (CSR) as a business tool and as a way to promote food security in the global South, this article draws on 65 interviews with supply chain personnel and a 2013 survey of 250 smallholder farmers in Nicaragua. Contrary to private governance literature, Walmart's efforts to control supply chains in Nicaragua are not advancing rural sustainability; feelings of mistrust and unfairness persist among farmers, and many are returning to local markets to regain independence. This analysis extends our understanding of why CSR is failing to help agrarian societies and confirms CSR as principally a business strategy.     

Proteinase K challenged by a novel protease

Proteinase K is used in forensic DNA extraction methods for cell lysis and degradation of proteins. Here we compare Proteinase K with a novel protease. We conclude that there is no need to exchange Proteinase K in our methods.
