We study the ultraviolet asymptotics in An affine Toda theories with integrable boundary actions. The reflection amplitudes of non-affine Toda theories in the presence of conformal boundary actions have been obtained from the quantum mechanical reflections of the wave functional in the Weyl chamber and used for the quantization conditions and ground-state energies. We compare these results with...

Reflection amplitudes are defined as two-point functions of certain class of conformal field theories where primary fields are given by vertex operators with real couplings. Among these, we consider (Super-)Liouville theory and simply and non-simply laced Toda theories. In this paper we show how to compute the scaling functions of effective central charge for the models perturbed by some primar...

BACKGROUND Reflection on experience is an increasingly critical part of professional development and lifelong learning. There is, however, continuing uncertainty about how best to put principle into practice, particularly as regards assessment. This article explores those uncertainties in order to find practical ways of assessing reflection. DISCUSSION We critically review four problems: 1. I...

Adrian Y.L. Chan, Ph.D University of Nebraska, 2010 Advisor: Fred Luthans This study proposes that being reflective or ruminative about one's leadership experience can have differential effects on one's leadership efficacy, implicit leadership theories and psychological capital. Specifically, through the aid of an event history calendar, conscript military trainees of high and low military expe...

This paper analyzes the edge-reflection problem of obliquely incident guided waves in a plate. The generalized guided-wave theories in a plate, including the orthogonality of modes and the mode-decomposition method are summarized. The edge-reflection problem is solved on the basis of the mode-decomposition method. Some numerical results are presented and compared to experimental results. [doi:1...

Professional organisations and regulatory bodies are making critical reflection a mandatory component of professional practice. Reflection is a vital part of learning from experience and is central to developing and maintaining competency across a practitioner's lifetime. This paper will discuss key educational theories to illustrate why reflection is important. Kolb's and Gibbs' reflective cyc...

This study investigated the role of knowledge building in fostering conceptual and epistemological changes in the context of Grade 10 chemistry students collaborating on Knowledge Forum in a Hong Kong classroom. Participants were 40 experimental and 39 comparison students experiencing knowledge building and traditional instruction respectively. Students engaging in knowledge building posed ques...

Coaching is inherently a reflective process. Constructivist theories of learning are well established and greatly inform thinking on coaching. The coaching practitioner literature promotes activities and offers many tools to aid reflection. While psychology provides some very pertinent theory, a review of practitioner literature finds little to help coaches understand how reflection actually wo...
