We investigated the influence of non-cued working memory representations on further information processing. A retro-cue indicated if items on the left or right side of a previous memory array remained relevant. Subsequently, a central probe item was presented with a varying stimulus onset asynchrony (SOA: 300, 400, 600, 1,000, 1,800 ms). Participants had to state whether this stimulus was shown...

Even though information is spatially and temporally irrelevant, it can influence the processing of subsequent information. The present study used a spatial cuing paradigm to investigate the origins of this persisting influence by means of event-related potentials (ERPs) of the EEG. An irrelevant color cue that was either contingent (color search) or non-contingent (shape search) on attentional ...

Die „Komponente“ Mensch stellt einen wesentlichen und erfolgskritischen Faktor bei der Realisierung von Service-orientierten Architekturen (SOA) dar. SOA erfordert neue Rollen und bringt neue Aufgaben mit sich. Auf operativer Ebene agiert das Skills-Management, welches durch geeignete Methoden sicherstellt, dass Personal korrekt ausgewählt bzw. passend weitergebildet wird. Skills-Management ist...

This research provides a theoretical conceptualization of SOA governance aspects that can be used to assess SOA governance practices and provide guidance to improve them. The review of IT and SOA governance shows that there are conflicting claims and inconsistency in the literature concerning the role of SOA governance. Moreover, there is no empirical evidence on the implications of the governa...

in this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. the engines are assumed to be implemented as composite web services. current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. the difficulty is to rollback the execution state of the workflo...

Service Oriented Architecture (SOA) is emerging to be the predominant architectural style of choice for many organizations due to the promised agility, flexibility and resilience benefits. However, there are currently few SOA metrics designed to evaluate complexity, effort estimates and health status of SOA solutions. This paper therefore proposes a SOA metrics framework which includes both ser...

Despite the wide range of advantages which many authors associate with the introduction of a service-oriented architecture (SOA), comprehensive SOA implementations continue to be scarce in practice. Consequently, questions arise as to how the concept is adapted in practice. This paper compares the scientific view of SOA concepts with initial practical experience from first SOA implementations. ...
