    Past as global trade governance prelude: reconfiguring debate about reform of the multilateral trading system

    This paper peers backwards into the history of the multilateral trading system and its development over the past half century as a means of considering what may lie beyond the horizon for the future of global trade governance. Its purpose is to underscore the necessity and urgency for root-and-branch reform of the multilateral trading system. It achieves this by comparing and contrasting the global trading system of 50 years ago with its modern-day equivalent and its likely future counterpart half-a-century hence. In so doing, the paper throws into sharp relief not only the inadequacies of global trade governance today but also the damaging consequences of not fundamentally reforming the system in the near future, with a particular emphasis on the past, present and future development of the world’s poorest and most marginalised countries

    A Multilaboratory Comparison of Calibration Accuracy and the Performance of External References in Analytical Ultracentrifugation

    Analytical ultracentrifugation (AUC) is a first principles based method to determine absolute sedimentation coefficients and buoyant molar masses of macromolecules and their complexes, reporting on their size and shape in free solution. The purpose of this multi-laboratory study was to establish the precision and accuracy of basic data dimensions in AUC and validate previously proposed calibration techniques. Three kits of AUC cell assemblies containing radial and temperature calibration tools and a bovine serum albumin (BSA) reference sample were shared among 67 laboratories, generating 129 comprehensive data sets. These allowed for an assessment of many parameters of instrument performance, including accuracy of the reported scan time after the start of centrifugation, the accuracy of the temperature calibration, and the accuracy of the radial magnification. The range of sedimentation coefficients obtained for BSA monomer in different instruments and using different optical systems was from 3.655 S to 4.949 S, with a mean and standard deviation of (4.304 ± 0.188) S (4.4%). After the combined application of correction factors derived from the external calibration references for elapsed time, scan velocity, temperature, and radial magnification, the range of s-values was reduced 7-fold with a mean of 4.325 S and a 6-fold reduced standard deviation of ± 0.030 S (0.7%). In addition, the large data set provided an opportunity to determine the instrument-to-instrument variation of the absolute radial positions reported in the scan files, the precision of photometric or refractometric signal magnitudes, and the precision of the calculated apparent molar mass of BSA monomer and the fraction of BSA dimers. These results highlight the necessity and effectiveness of independent calibration of basic AUC data dimensions for reliable quantitative studies

    The Culture of the WTO: Why it Needs to Change

    No full text
    The WTO is an international organization with its own distinctive culture, which is derived from the practice and experience of the GATT. The WTO, however, is not the old GATT. The multilateral trading system was transformed into an international organization in 1995, and today, the WTO also administers a host of agreements that contain detailed rules regulating international economic activity. The membership of the WTO has grown to 150, the vast majority of which are developing countries. Most importantly, the trading system, which was once bi-polar, driven by the United States and the European Union, has changed dramatically to become multi-polar, with the large emerging economies, such as China, India and Brazil, becoming major economic powers in their own right. The WTO needs major surgery in order to respond effectively to the new political realities in the international economic system. The current impasse in the Doha Round is in large part due to the great transformation in geopolitical power relationships taking place in the world today. If the Round fails, it will not be the end of the WTO. On the contrary, it might provide a useful 'time out' for the multilateral system to find its new stride. A related problem is that the mandate of the WTO is no longer clear. This article suggests that WTO Members work together to define the new purpose and mandate of the WTO to make it relevant to governments, companies and people in the 21st century. Institutional reform of the WTO is needed to provide it with the architecture and decision making machinery that will allow it to become a vibrant, responsive and accountable organization. , Oxford University Press.
