Parallel programming on loosely coupled distributed systems involves many system dependent tasks such as sensing node availability, creating remote processes, programming inter-process communication and synchronization, etc. Very often these system-dependent tasks are handled at the programmer level. This has complicated the process of parallel programming on distributed systems. The portabilit...

Understanding the collaborations that arise between the instances of classes in object-oriented programs is important for the analysis, optimization, or modification of the program. Relationships have been proposed as a programming language construct to enable an explicit representation of these collaborations. This paper introduces a relational model that allows the specification of systems co...

There is an emerging amount of software for generating and manipulating XML documents. This paper addresses the problem of guaranteeing the validity of dynamically generated XML structures statically at compile time of an XML-based application. In the XOBE (XML OBJECTS) project we extend the object-oriented programming language Java by new language constructs. XML Schema is used for describing ...

Business model management is critical in the development of business models aimed to launch innovations and generate high venture performance. This study presents the use of personal construct theory and the repertory grid methodology, a new technique to explore central factors in entrepreneurs’ business model management. We identify typologies for business model management and underlying logic...

George Kelly claimed that there were no emotions in Personal Construct Theory (PCT). The present paper notes that Kelly did define four important emotions and reviews the work by McCoy in extending the range of emotions that can be explained by PCT. In addition, the theories of personality formulated by non-PCT psychologists (Paul McReynolds and Prescott Lecky), which are consistent with PCT an...
