Diagnostic negative information presents people with a motivational dilemma. Although negative feedback can provide useful information with which to guide future self-improvement efforts, it also presents short-term affective costs. We propose that construal level, jointly with the perceived changeability of the feedback domain, determines whether people choose to accept or dismiss such informa...

One of the most fundamental aspects of software engineering is the ability of software artifacts, namely programs, to interact and to produce applications that are more complex. This is known as interoperability, but, in most cases, it is dealt with at the syntactic level only. This chapter analyzes the interoperability problem from the point of view of abstract software artifacts and proposes ...

A re ective language allows us to access its interpreter to dynamically modify or extend the language semantics from within the same language. In the previous paper, we implemented a re ective language called Black, and showed that a directly executable interpreter can be implemented by duplicating and partially evaluating the metalevel interpreters without losing changeability. In this paper, ...

Existing researches suggest that the code clone (duplicated code) is one of the factors that degrades the design and the structure of software and lowers the software quality such as readability and changeability. However, the influence of code clones on software quality has not been quantitatively clarified yet. In this paper, we have tried to quantitatively clarify the relation between code c...

We use the marker-based stigmergy, a mechanism that mediates animal-animal interactions, to perform context-aware information aggregation. In contrast with conventional knowledge-based models of aggregation, our model is data-driven and based on self-organization of information. This means that a functional structure called track appears and stays spontaneous at runtime when local dynamism in d...

This paper describes an approach towards an adaptive software and system architecture for driver assistance systems (DAS). Rather than assuming a static configuration of electronic control units and software components used in current automotive systems, we propose an architecture approach to handle the diversity arising from dynamically changing software configurations as they will emerge in f...

VapCyc is a vapor compression refrigeration simulation tool which features charge management and component inter-changeability. In addition to the four basic cycle components, additional components, such as pipes, bypass valves and various auxiliary heat exchangers can be added to the system at run-time, rather than design time, making the simulation very user-friendly. The simulation is achiev...

This article describes the process of designing a point-andclick adventure game that aimed at using dream logic as the basis to create its narrative puzzles. The technical solution to tackle this challenge was using Procedural Content Generation (PCG) as the design approach, which was used expressively to recreate the instability and changeability of dreams. Although PCG brought about replayabi...
