For comparative purposes, and given the usual structure that CSR Codes tend to follow, the analysis has been developed around the three most emphasized issues -namely, labor and human rights, environment and socio-economic issues -which in turn have been divided into common subcategories of CSR Codes. One can argue that if CSR Codes are actually based on the new international sustainable development law, which may be used to verify CSR Codes' compliance and enforcement, CSR Codes can be seen as a «global commons» understanding framework to improve sustainable development operations in emerging markets such as Brazil.

Specifically, an 8 % (w/v) NR/toluene solution was mixed with an 8 % (w/v) PCL/chloroform solution at proportions of 2, 15, 30, and 50 % (v/v). The morphological, thermal, and mechanical properties of the electrospun mats were investigated by scanning electron microscopy (SEM), differential scanning calorimetry, and uniaxial tensile tests. The SEM images demonstrated the production of micrometer-and sub-micrometer-sized fibers with no bead formation. Fibers with diameters ranging from 1.3 lm for samples with 0 % NR to 210 nm for samples containing 50 % NR were observed. Fibers with rough and smooth morphologies were observed, showing that the PCL/NR mats had phase-separated. The blend miscibility was evaluated by thermal analysis, which showed that blending did not improve the thermal stability of the systems. An investigation of the mechanical properties of the electrospun mats showed that adding NRL to the blend increased the tensile modulus, the ultimate elasticity, and the strain. Thus, non-vulcanized NR was successfully incorporated into electrospun mats, which exhibited useful mechanical properties that could be harnessed in biomaterials applications.

This study intends to corroborate this assertion by means of a comparative analysis of CSR codes of conduct of major oil and gas companies operating in emerging markets. In this paper, we examine how oil and gas companies respond to corruption in their CSR codes of conduct. Further, we examine the provisions related to corruption issues embodied in international conventions and guidelines and the norms or standards of oil and gas associations, NGOs and international and multilateral organizations. In the final analysis, we access the extent to which provisions included in oil and gas companies' CSR codes of conduct are consistent with the current international context.
