although investigating the factors that influence test scores is important, a majority of stakeholders show a paucity of attention towards individual learner differences due to having large classes of l2 learners. this study sought to explore the possible effect of working memory and cognitive style on l2 learners’ metaphorical test performance. the study was conducted in 2 phases. the first ph...

This paper introduces a “qualitative” problem solving task that humans arc adept at, but one which has not received much attention within the qualitative physics community. This is the task of predicting the operation of a simple mechanical device, itt tertits of spatial behaviors of its components, front a labeled schematic ciiagranm of the device showing the spatial cotmfigttration of its com...

In the treatment of superficial lesions with 8-13 MeV electrons, lead shields are often used to protect the underlying tissue. Measurements were made with film and ion chamber to analyse various aspects of external and internal shielding in electron beam therapy. Data were obtained on the thickness of lead required for shielding, the effect of blocking on dose-rate, electron-backscattering from...

Creating systems that can work with people as apprentices, learning from them in natural ways, is a long-standing goal of AI. Being able to teach systems new concepts via sketching is an important step towards this goal. This paper explores the role of qualitative representations in learning geographic concepts indicated on 2D maps. We propose three principles for representation bias when learn...

In this paper we present a strategy and a set of algorithms for developing qualitative positioning services that provide a qualitative location optimised for the environment where they are to be deployed. We argue that for many contextaware applications this may be more appropriate than more common quantitative location systems, where the positioning API may make unrealistic demands on the unde...

Fault diagnosis can be facilitated by using either quantitative and qualitative information of the system monitored. This paper presents a novel approach to integrate quantitative and qualitative information in fault-diagnosis, based on the use of neuro-fuzzy systems. In this approach the diagnostic signals residuals are generated and evaluated via a B-Spline functions network. The configuratio...

BACKGROUND Dealing with dependency in the elderly and their families leads us to explore the life experience of those involved together with the processes of adaptation to this condition. A number of original studies have been published which, following a qualitative methodology, have dealt with both dimensions. METHODS/DESIGN OBJECTIVES 1) To present a synthesis of the qualitative evidenc...
