title: Utility in WTP space: a tool to address confounding random scale effects in destination choice to the Alps

authors: Scarpa, Riccardo

subjects: mixed logit

abstract: Destination choice models with individual-specific taste variation have become the presumptive analytical approach in applied nonmarket valuation. Under the usual specification, tastes are represented by coefficients of site attributes that enter utility, and the distribution of these coefficients is estimated. The distribution of willingness-to-pay (WTP) for site attributes is then derived from the estimated distribution of coefficients. Though conceptually appealing this procedure often results in untenable distributions of willingness to pay. An alternative procedure is to estimate the distribution of willingness to pay directly, through a re-parameterization of the model. We compare hierarchical Bayes and maximum simulated likelihood estimates under both approaches, using data on site choice in the Alps. We find that models parameterized in terms of WTP provide more reasonable estimates for the distribution of WTP, and also fit the data better than models parameterized in terms of attribute coefficients. This approach to parameterizing utility is hence deemed promising for applied nonmarket valuation.

title: Supporting mobile application development with model-driven emulation

authors: Bowen, Judy

subjects: design

abstract: In this paper we outline our proposed approach for supporting mobile application development by using models as inputs to an emulator. We describe a new user interface to a parser tool previously developed, which enables developers to make design decisions about the user interface of the mobile application whilst ensuring that the resulting application adheres to the models. This paper describes work currently in progress.

title: Bilingual behaviour checklists: initiating a student, teacher and parent partnership in behaviour management.

authors: Glynn, Ted

subjects: bilingual education

abstract: Three bilingual (Maori and English) behavioural checklists formed part of a project designed to facilitate student, teacher and whanau collaboration in overcoming behavioural difficulties experienced by Maori students, (Hei Awhina Matua). The checklists assessed rankings by 163 students, 21 teachers and 96 whanau members of (1) contexts in which problem behaviours occur, (2) specific problem behaviours and (3) specific most valued behaviours. Data were gathered in three schools: a mainstream intermediate school with a Māori medium syndicate of three classes, a rural Kura Kaupapa Maori (Maori-controlled total immersion school) and a bilingual contributing primary school. While the three schools differed markedly in location, size, and in the proportion of Maori students enrolled, the rankings of settings and behaviours by students, teachers and whanau in each school were highly similar. The paper discusses how these data contributed to the design and development of the Hei Awhina Matua video and training manual, and provided a first step towards a collaborative student teacher and parent partnership in the management of student behaviour.
