Object-oriented (OO) technology was expected to rapidly replace traditional functional software technology due to its productivity and quality improvement potential in software development. Still, OO technology is not yet fully understood and utilized by information systems (IS) organizations. Despite the growing interest and attention of the IS researchers and practitioners, empirical research...

In the pair of papers of which this is Part I, the agent-oriented modeling perspective to cope with biological complexity is discussed. Three levels of dynamics are distinguished and related to each other: dynamics of externally observable agent behavior, dynamics of internal agent processes, and dynamics of multi-agent organisations. Basic agent concepts to describe externally observable agent...

The timely fixing of bugs is important to ensure software quality. In Open Source Software (OSS) development, behaviors of stakeholders impact the bug fixing process, especially the different stages respectively. However, most of the existing studies on impact factors of bug fixing time usually treat bug fixing process as a whole, while neglecting the particularity at its different stages. Igno...

This paper presents an approach to integrate the concepts of indefinite information with certainty factor in an object-oriented framework. In this work, the concept of traditional indefinite information is extended to include certainty factors so that indefiniteness can be measured. Indefinite information with certainty factors is classified into two categories: certainty factors of association...

An oriented graph is a directed graph which can be obtained from a simple undirected graph by orienting its edges. In this paper we show that any oriented graph G on n vertices with minimum indegree and outdegree at least (1/2 − o(1))n contains a packing of cyclic triangles covering all but at most 3 vertices. This almost answers a question of Cuckler and Yuster and is best possible, since for ...

Estimation of human orientation is considered a key configuration to study and understand human behaviours. There have been many works focusing on this. However, most of previous works are sensor-based technologies but visual-based technologies. In this paper, we proposed a method to estimate the orientation of human in a given image patch. We have observed the performance of a feature called H...

Service-orientated architecture is a very popular approach for building large scale, modular and distributed systems as well as achieving integration in heterogeneous environments. Its acceptance in the world of business is growing over time, mainly in technologically advanced countries, but there are still research gaps regarding SOA adoption and diffusion process. Interesting research questio...

Service-oriented computing is an emerging IT innovation. Among its manifestations is service-oriented architecture (SOA), an architectural approach to designing and implementing IT solutions. Academic empirical research on SOA adoption is scarce, with many studies focussing on qualitative analysis. The purpose of this study is to explore SOA adoption using a quantitative approach. This study in...
