Open source software systems are critical infrastructure for many applications; however, little has been precisely measured about their quality. Forecasting the field defect-occurrence rate over the entire lifespan of a release before deployment for open source software systems may enable...

Experimental economics has emerged and matured as a formal method for questioning and stress testing economic theory and assumptions concerning individual behavior. More recently, experimental methods have been used successfully in an economic laboratory to test alternative environmental policy...

The emergence of online labor markets makes it far easier to use individual human raters to evaluate materials for data collection and analysis in the social sciences. In this paper, we report the results of an experiment - conducted in an online labor market - that measured the effectiveness of...

Software testing is an indispensable activity in quality assurance andan enduring topic of research. For decades, researchers have beeninventing new and better techniques to test software. However, notesting technique will ever be a panacea for all softwaredefects. Therefore, while researchers...

It has recently been aptly emphasized that how models are used is essential to what scientific models are. But the explanations of why and how a model is used or why a model is scientifically valuable are still merely in terms of the relation between the model and its target, just as they were...

In this paper, I would like to show that considering technological models as they arise in engineering disciplines can greatly enrich the philosophical perspective on models. In fluid mechanics, (at least) three types of models are distinguished: mathematical, computer and physical models. Very...
