In this paper, necessary and sufficient conditions are stated for the Craig-Sakamoto equation det(I − sA − tB) = det(I − sA)det(I − tB) to hold for all scalars s, t ∈ C. Moreover, spectral properties for matrices A and B that satisfy this equation are investigated.

In this paper we sketch a multi-step scenario of a teacher and her classroom, who uses a few computer-based learning tools and their attached teaching analytics views. The tools that are described are extensions of the toolset of the authors (ComIn-M and SMALA) and others; the scenarios should thus serve as user-story in the design of future analytical softwares that support the teacher’s manag...

Shakespeare's Romeo and Juliet starts out as a classic love story: boy meets girl, boy falls in love with girl, boy and girl get married. Of course, it turns into a tragedy when they realize that their relationship is destined to fail. Surprisingly, many offices in corporate America follow a similar-though less morbid--trend.
