Online learning: new models for leadership and organization in higher education

Online learning is now reaching the core, helping to transform higher education and moving beyond isolated efforts to pervasive influence and change. The dichotomy of distance learning vs. campus-based education has broken down, and forward-looking senior administrators have embraced new approaches to education that contain the elements of successful online education while cultivating the community-building and branding of site-based education, particularly to promote enriched faculty and program development. Rather than being isolated in a distance learning task force or continuing education program, the conversations about online learning now occur – or need to occur – at the executive level and throughout other levels and structures.

Space-Optimal, Wait-Free Real-Time Synchronization

We consider wait-free synchronization for the single-writer/multiple-reader problem in small-memory embedded real-time systems. We present an analytical solution to the problem of determining the minimum, optimal space cost required for this problem, considering a priori knowledge of interferences—the first such result. We also show that the space costs required by previous algorithms can be obtained by our analytical solution, which subsumes them as special cases. We also present a wait-free protocol that utilizes the minimum space cost determined by our analytical solution. Our evaluation studies and implementation measurements using the SHaRK RTOS kernel validate our analytical results.
