    Transparency and sustainability in global commodity supply chains

    Over the last few decades rapid advances in processes to collect, monitor, disclose, and disseminate information have contributed towards the development of entirely new modes of sustainability governance for global commodity supply chains. However, there has been very little critical appraisal of the contribution made by different transparency initiatives to sustainability and the ways in which they can (and cannot) influence new governance arrangements. Here we seek to strengthen the theoretical underpinning of research and action on supply chain transparency by addressing four questions: (1) What is meant by supply chain transparency? (2) What is the relevance of supply chain transparency to supply chain sustainability governance? (3) What is the current status of supply chain transparency, and what are the strengths and weaknesses of existing initiatives? and (4) What propositions can be advanced for how transparency can have a positive transformative effect on the governance interventions that seek to strengthen sustainability outcomes? We use examples from agricultural supply chains and the zero-deforestation agenda as a focus of our analysis but draw insights that are relevant to the transparency and sustainability of supply chains in general. We propose a typology to distinguish among types of supply chain information that are needed to support improvements in sustainability governance, and illustrate a number of major shortfalls and systematic biases in existing information systems. We also propose a set of ten propositions that, taken together, serve to expose some of the potential pitfalls and undesirable outcomes that may result from (inevitably) limited or poorly designed transparency systems, whilst offering guidance on some of the ways in which greater transparency can make a more effective, lasting and positive contribution to sustainability

    How to optimize communication about animal and animal-free research methods

    Get PDF
    There is a long-standing debate about experimental non-human animals and animal-free methods in scientific research. Among the various stakeholders involved in the debate are the scientists. During media broadcasts we, animal researchers and animal-free methods researchers, were positioned as ‘opponents’. In this essay we describe our initial rational thoughts and emotions after these events, and how we came together to explore our common ground on animal(−free) experimentation. Realizing that all models have advantages and limitations, our common ground lies in the principles of good scientific research and responsible experimentation. Our communication emanating from the broadcasts has been instrumental in improving communication on animal(−free) experimentation issues by teaming up. We strongly believe that this is essential for making well-informed decisions for the methods we are using now and will be using in the future

    The Roots of Virtue: A Cross-Cultural Lexical Analysis

    Although the notion of virtue is increasingly prominent in psychology, the way it has been studied and conceptualised has been relatively Western-centric, and does not fully account for variations in how it has been understood cross-culturally. As such, an enquiry was conducted into ideas relating to virtue found across the world’s cultures, focusing specifically on so-called untranslatable words. Through a quasi-systematic search of academic and grey literature, together with conceptual snowballing and crowd-sourced suggestions, over 200 relevant terms were located. An adapted grounded theory analysis identified five themes which together provide an insight into the “roots” of virtue (i.e., the main sources from which it appears to spring): virtue itself (the concept of it); considerateness (caring about it); wisdom (knowing what it consists of); agency (managing to be/do it); and skill (mastery of the preceding elements). The results help shed further light on the potential dynamics of this important phenomenon

    Diamine oxidase:An overview of historical, biochemical and functional aspects

    No full text
    This article is a review of the historical, biochemical, and functional aspects of the enzyme diamine oxidase (DAO). The amine oxidase DAO, formerly called histaminase, is found in various tissues, but is especially active in the intestinal mucosa. Its function is the oxidative deaminating of several polyamines, essential substances for cell proliferation. DAO is thus a regulating enzyme in rapidly proliferating tissues such a bone marrow and intestinal mucosa. Results from several studies have demonstrated that both ornithine decarboxylase (ODC) and DAO activity rise during adaptive hyperplasia seen after small bowel resection. The ODC-dependent increase in polyamine content and subsequent increase in cell proliferative activity is probably downregulated locally in the villus tip by the increased DAO activity. DAO is normally present in very small amounts in the circulation and its basal plasma levels are positively correlated with the maturity and integrity of the intestinal mucosa. After intravenous administration of heparin, DAO is released from its capillary binding sites in the lamina propria into the peripheral circulation. Measurement of postheparin DAO release enhances its sensitivity and is now extensively studied to assess its value as follow-up or screening test for several enteropathies. Measuring basal as well as postheparin DAO levels has potential relevance following small bowel transplantation. Rejection of the small bowel graft leads to mucosal damage, which could conceivably lead to changes in DAO activity.</p
