Confronting Mathematical Pseudo-Community: A Domain-specific Analysis of a Middle School Mathematics Department [PDF]
EURASIA Journal of Mathematics, Science and Technology Education, 2019 Teacher professional community refers to the extent to which teachers collaborate to further their own and their students’ learning. Peck (1995) drew distinctions between pseudo-community and professional community, where pseudo-communities rely on suppression of conflict and the tacit understandings that it is “against the rules” to challenge others ...

Technical Analysis Techniques versus Mathematical Models: Boundaries of Their Validity Domains [PDF]
, 2006 We aim to compare financial technical analysis techniques to strategies which depend on a mathematical model. In this paper, we consider the moving average indicator and an investor using a risky asset whose instantaneous rate of return changes at an unknown random time. We construct mathematical strategies.
