We present a systematic means of designing serviceoriented systems. Because services are developed independently, with no prior knowledge about each other, there is only a limited possibility that such services use similar message templates, initiate calls to any other service, or generate messages to support desired architecture configurations. As a result, construction of service-oriented sys...

In activity-centric environments where people from different companies and disciplines work remotely together and where new virtual teams are formed and dissolved continuously, how to find the most suitable collaboration partner for a given task and how well one partner is able to collaborate with another one are challenging research questions. Determining and considering people’s professional ...

A shift occurred in research about adolescents in the general population. Research is moving away from deficits toward a resilience paradigm and understanding trajectories of positive youth development. This shift has been less consistent in research and practice with African American youth. A gap also exists in understanding whether individual youth development dimensions generate potential in...

Companies increasingly face turbulent and dynamic environments characterized by mostly unforeseeable changes. A viable strategy to survive in such environments is to strengthen organizational agility, which denotes the ability to quickly cope with continuous unanticipated change and to take advantage of opportunities in the environment. Serviceoriented architecture (SOA) accompanied by related ...

This article introduces a formal evaluation methodology for IT investments specifically designed to cope with the needs of port industry. Port industry is a service-oriented industry and, as such, is characterised by the intangible nature of benefits. The goal of this paper is to develop a methodology for the evaluation of container terminal related electronic services that incorporates both st...

Von einem Überwachungssystem zur Begleitung von Personen innerhalb von Gebäuden wird häufig gefordert, sich in die bestehende Anwendungslandschaft eines Unternehmens integrieren zu lassen und vorhandene Anwendungsfunktionalität möglichst wiederzuverwenden. Anwendungslandschaften werden verstärkt in Form dienstorientierter Architekturen strukturiert, weshalb ein integrierbares Überwachungssystem...

As aspect-oriented programming techniques move into mainstream use, it is likely that more software developers will be modeling systems with aspect-oriented features using the Unified Modeling Language. And with the Object Management Group considering revised standards for UML 2.0, it is an appropriate time to consider UML standards for aspect-oriented elements. This paper considers how aspect-...

Service-oriented architectures focus on the alignment of business processes and the supporting information technology. To facilitate the alignment and to decrease administration costs we propose linking of SOA services to enterprise models respectively target state organisational models by using semantically enriched conceptual modelling languages. Acting on language meta-level means in this co...

The Service oriented architecture Modeling Language (SoaML) is a new specification from the Object Management Group (OMG) that provides support for modelling services. The SoaML specification defines three different approaches to specifying services; simple interfaces, service interfaces and service contracts. In this paper we provide an overview of the SoaML language constructs and discuss the...
