In this article, we present a systematic mapping study of replications in software engineering. The goal is to plot the landscape of current published replications of empirical studies in software engineering research. We applied the systematic review method to search and select published articles, and to extract and synthesize data from the selected… (More)
This study set out to explore the views and motivations of those involved in a number of recent and current advocacy efforts (such as open science, computational provenance, and reproducible research) aimed at making science and scientific artifacts accessible to a wider audience. Using a exploratory approach, the study tested whether a consensus exists… (More)
Software teams often have trouble coordinating shared work due to poor communication practices. We surveyed software engineers (N=989) at Microsoft to investigate three rarely explored aspects of coordination: (1) how an engineer's perception of dependence is predicted by his organizational characteristics, (2) how this perception differs when the… (More)
Goal modeling and analysis techniques help stakeholders consider possible tradeoff alternatives in their requirements and answer " what if " questions about those alternatives. Software projects today exist in an ephemeral state, and current goal modeling approaches do not answer questions about model evolution and changes in actors' intentionality. We have… (More)
Many iStar-based modeling and analysis tools have been developed for specific iStar-related purposes (e.g., tools enumerated in iStar wiki). Despite the proliferation of tools, new tools keep being built, taking resources and time and possibly " reinventing the wheel " in terms of tool functionality. To gain an in-depth understanding of this situation , we… (More)
Goal models for early phase requirements enable modelers to elicit stakeholders' intentions, analyze dependencies and select preferred alternatives. Standard analysis techniques provide options for analysis of static goal models but do not consider the dynamic environment that the model represents and do not evaluate the intentions over time. In this… (More)
We report on the first direct nanoscale imaging of elementary edge dislocations in a thermotropic smectic-C* liquid crystal with the Burgers vector equal to one smectic layer spacing d. We find two different types of dislocation profiles. In the dislocation of type A, the layers deformations lack mirror symmetry with respect to the plane perpendicular to… (More)
We have looked at ways in which family farmers have become marginalized within the software ecosystem.
