A reflection in a real vector space equipped with a positive definite symmetric bilinear form is any automorphism that sends some nonzero vector v to its negative and pointwise fixes its orthogonal complement, and a finite reflection group is a discrete group generated by such transformations. We note two important classes of groups which occur as finite reflection groups: for a 2-dimensional v...

Virtual Exchange projects in initial teacher education provide various professional development opportunities for the pre-service teachers. This study explores reflection-in-action practices of teachers transnational teams while creating collaborative lesson plans a trilateral project. By exclusively focusing on screen-recordings video-mediated interactions using multimodal Conversation Analysi...

In leech mechanosensory neurons, action potentials reverse direction, or reflect, at central branch points. This process enhances synaptic transmission from individual axon branches by rapidly activating synapses twice, thereby producing facilitation. At the same branch points action potentials may fail to propagate, which can reduce transmission. It is now shown that presynaptic action potenti...

Community-based and participatory research methods challenge many commonly held beliefs regarding the basic nature of research and the ethics that inform our research practices. Action research, the term commonly used to refer to a broad range of these more collaborative research approaches, “seeks to bring together action and reflection, theory and practice, in participation with others, in th...
