Many studies investigate the upstream issues of BOT projects such as concessionaire selection criteria and risk factors. But the project execution becomes complicated such as the escalated quality supervision organization and procedure at the construction stage. This extra supervision may have constituted hidden redundancies as waste to economic sustainability. This paper investigated construction quality supervision of BOT projects to pinpoint adequate degree of supervision and detect redundant organization and procedures. The study adopted ten subway construction projects as cases in which five were from the traditional design-bid-build （DBB） and five from the BOT methods. Thirty six project participants including owners, contractors, designers, and concessionaire managers of the ten projects were interviewed to tell their views on these issues. The quality supervision measures of the DBB projects were used as the baseline and compared with those of the BOT projects. The research results show that the construction quality seems no difference for the DBB and BOT projects. Construction quality comes out of supervision but excessive supervision organization and procedures do not necessarily improve quality. This finding indicates that adequate degree of supervision is enough to achieve required quality to save immense paperwork for large construction projects.展开更多

But the plethora of recent corporate failures profession and has some ethical rules of thumb to and scandals where auditors＇ instrumental role is evident in many instances raise question about the validity and suitability of ＂self-regulation＂ in auditing, especially in the 21st century where auditors need to perform auditing in ever complex risk management process. Moreover, to restore the market confidences within the auditing profession and to raise the overall audit quality, many countries are establishing some super regulatory bodies to oversee the functions of auditing and auditors. Based on the ＂documentary research methodology＂, the author examines whether ＂self-regulation＂ in auditing has completely failed in the 21 st century. The author reveals that ＂self-regulation＂ in auditing has not completely failed; rather, a joint approach is needed to raise the overall quality of auditing where there will be equilibrium between ＂self-regulation＂ and statutory directive.展开更多
