In Introductory Computer Science courses, especially Computer Science 1 (CS1), dropout rates are generally high and results are often disappointing. In order to motivate and engage students to achieve better results in CS1, our teaching strategy is based on designing several activities using a competences oriented approach. This paper describes the use of a framework proposed by Crismond and Ad...

A shift is occurring in the Information Systems (IS) paradigm towards integrating IS activities with business activities. To investigate this development further, the study examined business performance measurement frameworks, and adopted these in compiling IS effectiveness measures relevant to the business environment. The IS executives of Australia's 200 largest companies were surveyed to est...

An Automated Video Surveillance system is presented in this paper. The system aims at tracking an object in motion and classifying it as a Human or Non-Human entity, which would help in subsequent human activity analysis. The system employs a novel combination of an Adaptive Background Modeling Algorithm (based on the Gaussian Mixture Model) and a Human Detection for Surveillance (HDS) System. ...

Nowadays, utilizing EA by enterprises with medium and long term goals causes improvement in their productivity and competitiveness. With respect to varied changes in enterprise's business activities and attitudes, flexibility in information systems of EA is a crucial factor. Agent's capacities in implementation of complex systems goal convince huge enterprises to use agent oriented architecture...

Service selection and composition are central activities in service-oriented computing, and the prediction of the QoS attributes of a Service-Oriented Architecture (SOAs) plays a key role to appropriately drive these activities. Software composition driven by QoS criteria (e.g., optimization of performance, maximization of reliability) has been mostly studied in the Component-Based Software Eng...

Purpose – The purpose of this paper is to address two questions: what is the difference between relationship processes and purely product-oriented processes? And to answer this question we should bear in mind what we mean by relationship, and why a customer is willing to establish and maintain a relationship at all. Design/methodology/approach – An empirical analysis subjected the motives of cu...

A basic stance for almost all learning theories is that a person learns by (inter-)acting with his/her environment. So, in order to formalize a learning process it is necessary to categorize its activities and environment. Recent developments in the learning domain support both formalizations broadly: Activity Theory (AT) provides a unified view of how to specify generic learning elements at a ...

In OMRON Corporation, we executed quality assurance activities in object-oriented software development and verified its effectiveness. We applied the formal description of use-cases and a design review process to the upper stream of our object-oriented software development process in a closely related manner. The project team consisted of both, software developers and corporate Software Enginee...
