Many concepts require generalizing number. For example, concepts such as momentum and energy conservation apply to arbitrary numbers of physical objects, clearing the top of a desk can require an arbitrary number of object relocations, and setting a table involves an arbitrary number of guests. In addition. there is recent psychological evidence [Ahn87] that people can generalize number on the ...

In this paper I tested whether Contradictory Matrix with 40 Inventive Principles, the simplest instrument from the Theory of Inventive Problem Solving (TRIZ), is a useful approach to a real-life PCR scenario. The PCR challenge consisted of standardization of fluorescence melting curve measurements in Competitive Amplification of Differentially Melting Amplicons (CADMA) PCR for multiple targets....

During the course of study for the Graduate Certificate of Education (Tertiary Teaching) we participated in a seminar about Problem Based Learning (PBL) and were asked to write a piece of assessment about this topic. I struggled long and hard with PBL and came up with a fairly mediocre piece of work to be assessed. This led me to an interest in PBL itself and, to the writing of this general ove...

In instance-based learning the classification of a novel instance relies upon experience given in the form of similar instances whose labels are already known. Each of these instances can hence be seen as an individual piece of evidence. In this paper, we elaborate on issues concerning the representation and combination of such pieces of evidence. Particularly, we argue that the information pro...

When a case-based planner is retrieving a previous case in preparation for solving a new similar problem, it is often not aware of all of the implicit features of the new problem situation which determine if a particular case may be successfully applied. This means that some cases may fail to improve the planner’s performance. By detecting and explaining these case failures as they occur, retri...

In the majority of cases, the pronoun it illustrates nominal anaphora, tending to refer back to another noun phrase in the text. However, in a significant minority of cases, the pronoun is used in exceptional ways that fail to demonstrate strict nominal anaphora. The identification of these uses of it is important in all fields where pronoun resolution has an impact. Following a survey of previ...
