Reasoning, Science, and the Ghost Hunt

This paper details how ghost hunting, as a set of learning activities, can be used to enhance critical thinking and philosophy of science classes. We describe in some detail our own work with ghost hunting, and reflect on both intended and unintended consequences of this pedagogical choice. This choice was partly motivated by students’ lack of familiarity with science and philosophic questions about it. We offer reflections on our three different implementations of the ghost hunting activities. In addition, we discuss the practical nuances of implementing these activities, as well the relation of ghost hunting to our course content, including informal fallacies and some models for scientific inference. We conclude that employing ghost hunting along-side traditional activities and content of critical thinking and philosophy of science offers a number of benefits, including being fun, increasing student attendance, enhancing student learning, and providing a platform for campus wide dialogues about philosophy

Buckling Analysis of Non-orthotropic Laminates by Means of B-Spline Functions

Whereas the buckling of rectangular laminate plates with symmetrical layup and an effectively orthotropic behaviour is well understood, the situation gets more complicated when an arbitrary symmetrical layup is admitted. Then twist coupling has to be taken into account. This can be accomplished in a consistent way by an energetic variational approach. In doing so, the use of B-spline functions turns out to be very appropriate for the deflection representation in connection with various kinds of boundary conditions. Validating finite element analyses show the good efiiciency of B-spline functions for the buckling analysis. The eflect of twist coupling on the resultant buckling loads turns out to be considerable. It can be both conservative and non-conservative and should always be taken into account carefully
