ABSTRACT Top management's involvement in IT governance appears to positively influence the establishment and implementation of effective IT governance within organizations. Considering the lack of advancement in the area in practice, this study offers a deeper understanding of dimensions that help to explain top management's knowledge of IT governance. Using absorptive capacity as its theoretical underpinning, and based on Australian empirical data, this study shows that for top management to achieve higher levels of absorptive capacity of IT governance knowledge (ACAP-ITG), they need to focus on four dimensions: prior relevant knowledge, effective communication network, appropriate communication climate, and effective knowledge scanning. To further support the usefulness of the ACAP-ITG construct, this study empirically tested the relationship between the construct and corporate performance. This study presents top management in organizations with useful measures that can help them assess their organization's strengths and weaknesses related to ACAP-ITG.

For the reliable communication network design (RCND) problem unreliable links are available, each bearing several options which have different levels of reliability and varying costs. The goal is to find the most cost-effective communication network design that satisfies a predefined overall reliability constraint. This paper presents two new evolutionary algorithm (EA) approaches to solving the RCND problem: LaBORNet and BaBORNet. LaBORNet uses an encoding that represents the network topology as well as the used link options while repairing infeasible solutions using an additional repair heuristic (CURE). BaBORNet encodes only the network topology and determines the link options by using the repair heuristic CURE as a local search method. The experimental results show that the new EA approaches using repair heuristics outperform existing EA approaches from the literature using penalties for infeasible solutions. They also find better solutions for existing problems from the literature, as well as for new and larger test problems.
