The Concept of Transparency in International Relations: towards a critical approach

Transparency is an important concept in International Relations. The possibility of realizing transparency in practice operates as a central analytical axis defining distinct positions on core theoretical problems within the field, from the security dilemma to the function of international institutions and beyond. As a political practice the pursuit of transparent governance is a dominant feature of global politics, promoted by a wide range of actors across a vast range of issue areas, from nuclear proliferation to Internet governance to the politics of foreign aid. Yet, despite its importance, precisely what transparency means or how the concept is understood is frequently ill-defined by academics and policy-makers alike. As a result, the epistemological and ontological underpinnings of approaches to transparency in IR often sit in tension with their wider theoretical commitments. This article will examine the three primary understandings of transparency used in IR in order to unpack these commitments. It finds that while transparency is often explicitly conceptualized as a property of information, particularly within rationalist scholarship, this understanding rests upon an unarticulated set of sociological assumptions. This analysis suggests that conceptualizing ‘transparency-as-information’ without a wider sociology of knowledge production is highly problematic, potentially obscuring our ability to recognize transparent practices in global governance. Understanding transparency as dialogue, as a social practice rooted in shared cognitive capacities and epistemic frameworks, provides a firmer analytical ground from which to examine transparency in International Relations.

Laccase-assisted bio-grafting of polyhydroxy-alkanoates (PHAs) onto the ethyl cellulose (EC) backbone

In the present study, a novel enzyme-based methodology for grafting Polyhydroxyalkanoates (PHAs) onto the ethyl cellulose (EC) as a backbone polymer was developed. Laccase assisted copolymerization was carried out under mild and eco-friendly reaction conditions. The resulting homogeneous composite membranes were characterized by Fourier-transformed infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and Atomic Force Microscopy (AFM). The FTIR spectra of pure PHAs and PHAs containing graft composites (PHAs-g-EC) showed their strong characteristic bands at 1721 cm1, 1651 cm-1 and 1603 cm-1 respectively. Other accompanying bands in the range of 900-1300 cm-1 correspond to C=O vibration and C-O-C bond stretching, which could be contributed from PHAs and EC, respectively. The high intensity of the 3358 cm-1 band in the graft composite may have corresponded to the degradation of the carboxylic group from PHAs and also showed an increase of hydrogen-bonded groups at that distinct band region. The morphology was examined by SEM, which showed the well dispersed PHAs crystals in the backbone polymer of EC. XRD pattern for PHAs showed distinct peaks at 2-Theta values of 28o, 32o, 34o, 39o, 46o, 57o, 64o, 78o and 84o that represent the crystalline nature of PHAs. In comparison with those of neat PHAs, the degree of crystallinity for PHAs-g-EC decreased and this reduction is mainly because of the new cross-linking of PHAs within the EC backbone that changes the morphology and destroys the crystallites. Improved mechanical properties were observed for the PHAs-g-EC as compared to the individual components due to the impregnation of EC as reinforcement into the PHAs matrix. Improved mechanical strength enhanced thermal properties, along with low crystallinity of the present PHAs-g-EC suggesting its potential for various industrial and bio-medical applications.
