title: Active learning of soft rules for system modelling

authors: Frank, Eibe

subjects: computer science

abstract: Using rule learning algorithms to model systems has gained considerable interest in the past. The underlying idea of active learning is to learning algorithm influence the selection of training examples. The presented method estimates the utility of new experiments based on the knowledge represented by the existing rulebase. An extended rule format allows to deal with uncertainty. Experiments with different artificial system functions show that the presented method improves the model quality respectively decreases the number of experiments needed to reach a specific level of performance.

title: Partial least squares structural equation modeling-based discrete choice modeling: An illustration in modeling retailer choice

authors: Hair, Joseph

subjects: Discrete choice modeling

abstract: Commonly used discrete choice model analyses (e.g., probit, logit and multinomial logit models) draw on the estimation of importance weights that apply to different attribute levels. But directly estimating the importance weights of the attribute as a whole, rather than of distinct attribute levels, is challenging. This article substantiates the usefulness of partial least squares structural equation modeling (PLS-SEM) for the analysis of stated preference data generated through choice experiments in discrete choice modeling. This ability of PLS-SEM to directly estimate the importance weights for attributes as a whole, rather than for the attribute’s levels, and to compute determinant respondent-specific latent variable scores applicable to attributes, can more effectively model and distinguish between rational (i.e., optimizing) decisions and pragmatic (i.e., heuristic) ones, when parameter estimations for attributes as a whole are crucial to understanding choice decisions.

title: Māori and English textbooks designed for language learners at intermediate level: A comparison in terms of the occurrence and use of insights from research on discourse analysis

authors: Fester, Anthea

subjects: New Zealand

abstract: Over the past two decades, research in the area of discourse analysis has expanded rapidly and has yielded insights that could usefully inform the teaching and learning of languages. In this paper, we report on the results of a comparative study of a number of commercially available textbooks designed for learners of English and learners of te reo Māori at intermediate level in terms of the extent to which they can be shown to have been influenced by specific aspects of discourse analysis research. In the textbooks designed for learners of English, there is some evidence that the writers are aware of, and have been influenced by some aspects of discourse analysis research, particularly in the teaching of writing skills. In the textbooks designed for learners of te reo Māori, however, there is almost no sign of influence of research of this type. In view of the importance of the teaching and learning of te reo Māori in relation to the maintenance of the language, and in view of the fact that many young people in New Zealand now learn a range of academic subjects through the medium of te reo Māori, this raises issues that we believe need to be addressed.
