In this paper we review the most common forms of reflection and introduce a new form which we call sharpgenerated reflection. We argue that sharp-generated reflection is the strongest form of reflection which can be regarded as a natural generalization of the Lévy reflection theorem. As an application we formulate the principle sharp-maximality with the corresponding hypothesis IMH#. IMH# is an...

We study the relationship between the semistationary reflection principle and stationary reflection principles. We show that for all regular cardinals λ ≥ ω2 the semistationary reflection principle in the space [λ] implies that every stationary subset of E ω := {α ∈ λ | cf(α) = ω} reflects. We also show that for all cardinals λ ≥ ω3 the semistationary reflection principle in [λ] does not imply ...

This paper explores the nature of reflection that qualified physiotherapists use in their day-to-day practice. is an area which there a dearth research. With grounded theory approach purposive sampling was used to recruit seven for photo-elicitation interviews exploring whether they did reflect and if so, what like. The findings were but it occurred outside working hours. Four conceptual catego...

The relevance of reflection for learning has long been recognised, and there is a substantial body of theoretical work on reflection. However, many questions regarding reflection at the workplace are still open, especially regarding the actual occurrence of reflection in different workplaces, and the efficient support for reflection. In our ongoing work to examine the relevance of reflective le...

Computational results have been obtained for the separate terms in the Fourier expansion of the reflection function of an optically thick, conservatively scattering, atmosphere composed of cloud particles. The computations were obtained by successive applications of the invariant imhedding. doubling and asymptotic fitting methods to cover the range from very thin to very thick atmospheres. Resu...

Reflection is widely accepted as a learning tool and is considered integral to professional practice. Journal writing is advocated in facilitating reflection, yet little is written about how to assess reflection in journals. The purpose of this study was to develop and test a method of assessing the elements of reflection in journals and to determine whether, and to what level, reflection occur...

This report presents an analytic framework for calculating BRDFs (bi-directional reflectance distribution function) of randomly rough surfaces. The fundamental assumptions are the tangent plane approximation and statistical approach sufficiency. By treating a local surface area as its tangent plane, the tangent plane approximation validates the description of waves using geometric rays, and the...

Computational reflection is a fundamental mechanism in object oriented languages. Reflection has proved useful in many contexts, such as in the design of development environments, language extension, and the dynamic, unanticipated adaptation of running systems. We identify three problems with the current approach to reflection in object oriented languages: partial behavioral reflection needs to...

This paper describes an analysis of reflection and transmission of acoustic waves from an imperfectly reflecting, rough fluid–fluid interface within the Kirchhoff approximation. It presents the results of calculations of the coherent and diffuse field. This work is motivated by the fact that few explicit results of the characteristics of the scattered and transmitted wave field exist in the lit...
