The purpose of this paper is to use quantitative data to describe corruption in the SANPS, and use Luo's ([Luo, Y., 2005]) institutional theory to gain insights into how corruption develops and remains entrenched despite the introduction of anti‐corruption legislation. A total of 1,500 questionnaires were distributed to public servants in nine provinces, but predominantly in Kwa Zulu Natal and Gauteng. There were 702 returned giving a response rate of 47%. We conclude that the findings discussed in this paper lend support for Luo's theoretical model being able to provide insight into the development of corruption, its consequences and possible remedies.
A range of polyimides have been subjected to electron beam radiolysis at different temperatures. These polyimides were chemically designed to suit space applications, being either transparent or having groups which provide oxidation resistance. The structural changes that occur in the polyimides, when subjected to electron beam irradiation doses up to 18.5 MGy and up to temperatures close to their glass transition temperatures, were studied using FT-Raman spectroscopy. The range of polyimides studied included a series of perfluoropolyimides, a silicon-modified polyimide, and Ultem. The changes in the Raman peak intensities of the different groups indicated scission reactions involving the imide rings and ether linkages. (c) 2006 Wiley Periodicals, Inc.
