Knowledge sharing and reuse in global software engineering (GSE) are challenging issues. Knowledge management (KM) is specifically impacted be-cause on top of distance, culture and language mismatches, there is also the per-ceived risk of sharing something which could mean that others could take over some work. Mistrust and protectionism are often...

Context There is a significant number of requirements engineering (RE) tools with different features and prices. However, existing RE tool lists do not provide detailed information about the features of the tools that they catalogue. It would therefore be interesting for both practitioners and tool developers to be aware of the state-of-the-art as...

In an increasingly globalized world, the diversity of languages and cultures of the students requires the adaptability of the learning environment to satisfy their needs and preferences.
