The dynamic behaviour of a software system changes as a consequence of developer’s static source code modifications. In this thesis, we improve upon a previous approach that combines static and dynamic analyses to categorize behavioural changes by greatly improving its accuracy through polymorphic mapping. We further refine the previous model by introducing a change-centric state transition model that captures the flow of call pairs among different partitions based on static and dynamic call graphs. We also extend the approach by incorporating complete dynamic call stacks into the analysis. Finally, we perform a longitudinal analysis of three software systems to categorize how they have dynamically evolved across 100 program versions. In our evaluation, the polymorphic mapping algorithm decreased mismatches between the static and dynamic analyses by 53%. In particular, we decreased the mismatch by 71% in the most important category of changes from the developer’s point of view. We found that developers introduce new behaviour more often than eliminating old behaviour. Our results show that developers are more likely to remove unexecuted/dead code than code that is executed dynamically. In terms of change types, we found that changes made to fix defects encountered the least inconsistent and unexpected behaviour, while changes made to add new functionality experienced the highest unexecuted behaviour. Finally, we argue that augmenting the dynamic analyses with call stacks provides useful information that helps developers analyze the implications of the call pairs highlighted by our analyses.

This study identifies four major areas for analysis and evaluation of current procedures and practices of EIA monitoring and auditing in three Australian jurisdictions: institutional arrangements; public accountablity, transparency and community involvement; approaches and techniques; and resources and capacity. Case studies involving EIA projects and surveys and interviews with EIA practitioners were conducted in South Australia, Western Australia and New South Wales. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1283764 / Thesis (Ph.D.) -- University of Adelaide, School of Social Sciences, 2007

It concludes that the Philippine EIS system, in spite of some shortcomings, performed satisfactorily though implementation and enforcement ha/ a lot of room for improvement.--The Philippines has one of the most comprehensive EIA laws and policies in Southeast Asia. The Philippine Environmental Impact Statement (EIS) System has undergone four phases of implementation as evidence that there is a continuous effort in improving its application. Originally conceived as a regulatory tool, the EIS system has slowly moved to being a management tool to aid decision makers in selecting the best alternative after examining the trade offs between social needs, environmental concerns and economic and financial viability of a project or activity. Recent reforms in the EIA implementing rules and regulations are expected to further enhance the administration and overall utility of EIA in the Philippines.--The Philippine EIS System is well advanced in comparison with Southeast Asia and some Western EIA systems. It has strong legal and regulatory frameworks and guidelines and procedures for its implementation are well set up. Through time, there have been amendments such as the social acceptability concept to enhance public participation, specific guidelines for scoping and the requirement of Environmental Guarantee and Monitoring Funds for compliance monitoring, which aimed at improving EIA implementation. However, compliance and enforcement are still insufficient due to the inherent problem of lack of financial and human resources and political support.--Donor agencies have been influential in the formulation and improvement in EIA implementation in the Philippines. The initial environmental policy in the Philippines that was formulated with the assistance from the US government became the foundation of the preceding environmental laws and policies. The Philippines has obtained a fair amount of EIA technical assistance from bilateral and multilateral donors to support institutional capacity building and to train EIA implementors, project proponents and non-government organisations and to build and upgrade environmental management facilities and equipment. Donors have little influence in the actual conduct of EIA in the Philippines. The Philippine EIS system has the same requirements and procedures from local and foreign-funded projects and all project proponents are required to comply. / Mode of access: World Wide Web. / xiii, 143 p. ill
