Introducing new methods of teaching and learning requires an institutional approach to professional development in order to cater for the different levels and requirements of staff. The increase in e-learning use has prompted many institutions to adopt a whole organisation approach to professional development for lecturers. This paper proposes to answer three related questions. How do instituti...

In this paper we study the qualification problem in theories of reasoning about actions and change and the link of this problem to properties of representation for expressing such theories. We examine the interaction of the qualification problem with the frame and ramification problems and show how an integrated solution to these problems can be developed where the frame persistence and constra...

In the past, students in England and Wales born within the first five months of the academic year could leave school one term earlier than those born later in the year. Focusing on women, those who were required to stay on an extra term more frequently hold some academic qualification. Using having been required to stay on as an exogenous factor affecting academic attainment, we find that holdi...

In this paper, we introduce a constant positive linear dependence condition (CPLD), which is weaker than the Mangasarian–Fromovitz constraint qualification (MFCQ) and the constant rank constraint qualification (CRCQ). We show that a limit point of a sequence of approximating Karush–Kuhn–Tucker (KKT) points is a KKT point if the CPLD holds there. We show that a KKT point satisfying the CPLD and ...

In this work we introduce a relaxed version of the constant positive linear dependence constraint qualification (CPLD) that we call RCPLD. This development is inspired by a recent generalization of the constant rank constraint qualification from Minchenko and Stakhovski that was called RCR. We show that RCPLD is enough to ensure the convergence of an augmented Lagrangian algorithm and asserts t...

P reparative chromatography is the dominant purification technique in the production of biological compounds, especially for bioseparations. The column used is central to the performance of the chromatographic step. To ensure robust and reproducible column performance, columns need to be qualified in an acceptable fashion before each use. Some of the critical elements of column qualification in...
