In this paper, we present formulas for the number of decompositions of elements of the Weyl groups of type A., D. and B, as products of a number of reflections that is not necessarily minimal. For this purpose, we consider the poset of conjugacy classes of W introduced in B6dard and Goupil (1992) for the symmetric group. This poset describes the action of the set of reflections of a reflection ...

In the present paper, the problem of light reflection from a birefringent medium and thin film is considered. First, the analytical equations governing the propagation of a plane and harmonic electromagnetic wave in an infinite, birefringent, linear, non-dispersive, non-absorbing, and non-magnetic medium is derived from Maxwell equations. Then, using phase matching condition and boundary condit...

Do we really know what critical reflection means in the context of work-integrated learning, more specifically cooperative education? Critical reflection, in some form, is located within many higher education programmes, including cooperative education and many educators would say this is important for in-depth student learning. It is a form of reflection that is complicated as well as challeng...

This paper portrays the ways Indonesian English Language Teaching (ELT) practitioners review and reflect on their practice, seek to expand new ideas techniques they can apply in classrooms. study aims enhance our understanding of what it is actually that ELT are doing, understanding, trying achieve classroom activities. investigates explanative answers a single research question: In reflective ...

This paper presents our approach of using hypertext representations to support a scholar in the early stages of a scholarly writing process. We take D. A. Schoen’s model of design as a theoretical framework. Schoen views design as a reflective conversation with the materials of a situation, where the designer interacts with the materials, such as pen and sketch on a sheet of paper, in the refle...

Utilising Rolfe's [Rolfe, G., 1998. Expanding Nursing Knowledge: Understanding and Researching Your Own Practice. Butterworth-Heinemann, Oxford] reflexive action research, one novice nurse educator explored current teaching practice. The data were collected from a reflective journal and colleague feedback. Through this data collection and applying Rolfe's (1998) understanding-action-evaluation ...
