This paper describes the design of Portfolio and its application at FH JOANNEUM in a range of contexts where it will be used to make learning outcomes visible and to facilitate personal development planning. The flexibility of the ePortfolio architecture is appraised and the integration with virtual learning environments is discussed. Preliminary findings from evaluation studies (feedback / dat...

The discovery of declarative process models by mining event logs aims to represent flexible or unstructured processes, making them visible to business and improving their manageability. Although promising, the declarative perspective may still produce models that are hard to understand, both due to their size and to the high number of restrictions of the process activities. This work presents a...

The success of multimedia enabled community engines depends on a careful design of the digital media and the related communication/collaboration tools. However, the semantics of the multimedia contents in community communication and collaboration is hard to capture and complex to compute. With the opportunities given by the combination of metadata descriptions standards like MPEG-7 and server-s...

The present investigation was concerned with the changeability of sense of coherence. We examined changes in sense of coherence (SOC) over a six-month period in a sample of Finnish unemployed individuals (n = 74) participating in an intervention program designed to boost re-employment. Over the study period, participants' sense of coherence improved significantly and re-employed individuals rep...

A key element to API technologies is the gateway. This is a Server architecture that provides the interface between client requests and the network services. Whilst it is in the interests of simplicity and ease of implementation for the client server interface to be as straightforward as possible, special consideration must be given to the interface to maintain security, integrity, scalability ...

a r t i c l e i n f o Pay-What-You-Want (PWYW) pricing is becoming increasingly popular in real-world applications, especially for cultural services and digital goods. Yet very little is known about the factors related to the customers' motivation of paying (e.g., fairness, getting a bargain). This research explores the relevance, the relative importance of these factors in PWYW contexts, and t...

Most information technology (IT) organizations are experimenting on adoption of the dual mode operation, involving traditional and agile methods work. These two incompatible development worlds need to be in sync for IT operate effectively. However, both types operation map onto generic project management principles allowing manageability projects. Management issues challenges presented as point...

Web service compositions (WSC), as part of a service-oriented architecture (SOA), have to be managed to ensure compliance with guaranteed service levels. In this context, a high degree of automation is desired, which can be achieved by applying autonomic computing concepts. This paper particularly focuses the autonomic management of semi-dynamic compositions. Here, for each included service sev...
