In this paper we propose a novel approach for the systematic assessment and analysis of IT related risks in organisations and projects. The approach is model-driven using an enterprise architecture as the basis for the security management process. Using an enterprise architecture it is possible to provide an integrated description of an organisation’s structure, processes and its underlying IT ...

IT risk management is an important challenge for businesses and software vulnerabilities are a major source of IT risks, as the 2006 CSI/FBI Computer Crime and Security Survey [GLLR06] demonstrates. According to the survey, many companies consider it important to quantify the losses attacks against their IT systems cause but are unable to do so. In service-oriented architectures, we see a promi...

The use of Information Technology (IT) in organizations is subject to various kinds of potential risks. Risk management is a key component of project management enables an organization to accomplish its mission(s). However, IT projects have often been found to be complex and risky to implement in organizations. The organizational relevance and risk of IT projects make it important for organizat...

Technical agility refers to the ability to quickly change the type and flow of information within an enterprise. Technical agility parameters are affected by enterprise architecture. IT advance has not yet satisfied business requirements due to improper software architectures. SOA addresses technical agility requirements by presenting composability, modularity, and loose coupling concepts as se...

Our review of the evidence found that the notion that higher pay leads to the selection of better executives is undermined by the prevalence of poor recruiting methods. Moreover, higher pay fails to promote better performance. Instead, it undermines the intrinsic motivation of executives, inhibits their learning, leads them to ignore other stakeholders, and discourages them from considering the...

This research analyzes manufacturing growth and decline across metropolitan and nonmetropolitan regions during the 1972–2002 period. We decompose real value added growth across local labor market areas in the lower 48 U.S. states into contributions from labor, capital, and total factor productivity. We then estimate a model describing the long-run growth of labor, capital, and productivity and ...

In 2011, Kumar et al. proposed an efficient password authentication scheme using smart cards to overcome the security flaws in Liao et al. scheme. However, in this paper, we point out that Kumar et al.’s scheme actually has various defects been overlooked, such as no provision of forward secrecy, poor repairability and practicality. More recently, Ramasamy and Muniyandi presented an efficient t...

Annotating photos is such a time-consuming, tedious and error-prone data entry task that it discourages most owners of personal photo libraries. B y allowing users to drag labels such as personal names from a scrolling list and drop them on a photo, we believe we can make the task faster, easier and more appealing. Since the names are entered in a database, searching for al l photos of a fiiend...

Africa's trade is impeded by poor infrastructure. Inadequate transport infrastructure raises costs analogous to trade barriers, while inadequate power discourages investment. Yet Africa's infrastructure needs greatly exceed its capacity to finance them. There is therefore a need, and an opportunity, for substantial foreign private finance. However, to date, while private finance routinely finan...

This paper considers migration as an investment decision. It develops a continuoustime stochastic model to explain the optimal timing of migration, in the presence of ongoing uncertainty over wage differentials. The results show that individuals prefer to wait before migrating, even if the present value of the wage differential is positive, because of the uncertainty and the sunk costs associat...
