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...

In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...

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...

The project management discipline is expanding within many engineering activities. This discipline can facilitate strivings toward successful accomplishment of an engineering project. Therefore, many academic institutes teach the “project management” program. This study presents a novel approach that educates engineering students to become successful project managers based on contextual learnin...

Ambivalence, the presence of positive and negative reactions toward an object, typically involves the subjective experience of conflict. We investigate the role that the perceived validity of each side of an ambivalent attitude plays in producing subjective ambivalence (SA). Consistent with the metacognitive model of attitudes, we demonstrated that SA is reduced when people doubt either the pos...

The functional perspective on attitudes suggests that individuals will be more persuaded by advertisements that match their individual needs or attitude functions. Although previous research provided correlational support for this functional approach, the current study aimed to provide a stronger, experimental test. A pilot study validated situational manipulations of the value-expressive and k...

We view match as an operator that takes two graph-like structures (e.g., XML schemas) and produces a mapping between the nodes of these graphs that correspond semantically to each other. Semantic schema matching is based on the two ideas: (i) we discover mappings by computing semantic relations (e.g., equivalence, more general); (ii) we determine semantic relations by analyzing the meaning (con...
