This study investigates the preferences of instructors and students for design and pedagogy features of online instruction at the post-secondary level. Participants included 60 instructors and 200 students at a comprehensive research university. Correlation coefficients of .95 on the design item rankings and .87 on the pedagogy item rankings were found between instructors and students. An indep...

We introduce a novel definition of a parabola into the framework of universal hyperbolic geometry, show many analogs with the Euclidean theory, and also some remarkable new features. The main technique is to establish parabolic standard coordinates in which the parabola has the form xz = y2. Highlights include the discovery of the twin parabola and the connection with sydpoints, many unexpected...

We discuss the canonical form for a pure state of three identical bosons in two modes, and classify its entanglement correlation into two types, the analogous GHZ and the W types as well known in a system of three distinguishable qubits. We have performed a detailed study of two important entanglement measures for such a system, the concurrence C and the triple entanglement measure τ . We have ...

Computing the entanglement of formation of a bipartite state is generally difficult, but special symmetries of a state can simplify the problem. For instance, this allows one to determine the entanglement of formation of Werner states and isotropic states. We consider a slightly more general class of states, rotationally symmetric states, also known as SU(2)-invariant states. These states are i...

Multi-Agent Systems should not be conceived as only cooperative. As open systems situations of concurrence, competition and conflict often arise. Starting from this perspective it is relevant not only pro-social interaction modeling, but also a theory of trust and monitoring, giving special relevance to issues of security and defense: how can an agent prevent that dangerous actions of other age...

The dynamics of two interacting spins coupled to separate bosonic baths is studied. An analytical solution in Born approximation for arbitrary spectral density functions of the bosonic environments is found. It is shown that in the non-Markovian cases concurrence " lives " longer or reaches greater values.
