title: Using flexible taste distributions to value collective reputation for environmentally friendly production methods

authors: Scarpa, Riccardo

subjects: environmentally friendly production

abstract: In this paper, we investigate consumer preferences for various environmentally friendly production systems for carrots. We use discrete choice multi-attribute stated preference data to explore the effect of the collective reputation of growers from an Alpine valley with an established reputation for its environmentally friendly production: Val di Gresta 'the valley of organic orchards.' Data analysis of the panel of discrete responses identifies unobserved taste heterogeneity for organic, biodynamic, and place of origin along with extra variance associated with experimentally designed alternatives. The assumed parametric taste distributions are each tested using the semi-nonparametric specification proposed by Fosgerau and Bierlaire, while the null of normality cannot be rejected for organic and biodynamic production methods, though it is for the place of origin. The latter is found to be bi-modal, with modes at each side of zero. The use of a flexible taste distribution increases the plausibility of this form of heterogeneity and it appears promising for future applied studies. 
Dans le présent article, nous avons examiné les préférences des consommateurs quant à divers systèmes de production écologiques de carottes. Nous avons utilisé des données sur les préférences déclarées, la valeur attendue et les choix discrets pour examiner l'effet de la réputation collective de producteurs dans une vallée alpine réputée pour sa production écologique: Val di Gresta, dite la ≪vallée des vergers biologiques≫. L'analyse des données de panel discrètes a fait ressortir une hétérogénéité inobservable des goûts quant à la culture biologique, la culture biodynamique et le lieu d'origine ainsi qu'une variance supplémentaire liée à des options expérimentalement conçues. Les distributions paramétriques hypothétiques des goûts sont testées à l'aide de la spécification semi-non-paramétique proposée par Fosgerau and Bierlaire (2007), tandis que l'hypothèse nulle de normalité(null of normality) ne peut être rejetée pour les méthodes de production biologique et biodynamique, bien qu'elle le soit pour le lieu d'origine. Cette dernière serait bimodale, avec des modes de chaque côté de zéro. L'utilisation d'une distribution des goûts souple augmente la plausibilité de cette forme d'hétérogénéité et semble prometteuse pour les études appliquées futures.

title: Deictic Framing Performance Fails to Generalize to Other Perspective-Taking Tasks

authors: Taylor, Tokiko

abstract: The behavioral processes underlying perspective taking have not been studied extensively. One approach to understanding and enhancing perspective taking, deictic framing, has been proposed. Proponents of this approach have suggested that deictic framing is a core property of perspective taking. A training protocol based on deictic framing has been developed and tested, but researchers generally evaluate the effectiveness of the protocol using tasks that have a similar format to the training protocol. Little research has examined the protocol’s effectiveness for improving performance in different perspective-taking tasks. We investigated generalization of the performance of three groups of university students trained with a deictic-framing protocol (or not) and tested with two other perspective-taking tasks: a visuospatial perspective taking using a cupboard containing a range of objects and a version of the implicit relational assessment procedure specifically designed to measure perspective taking. The first group was trained with the original verbal protocol with deictic expressions; the second group with the same protocol involving nondeictic words; and the third group was merely exposed to deictic expressions as a control condition. The results suggested that deictic framing is not fundamental to perspective taking, as the performance of the two experimental groups was not significantly different from the control group’s performance. Identification of specific stimulus functions involved in successful perspective taking and how those functions can be established should be addressed in future research.

title: Beyond Pākehā paralysis: Exploring the journeys & experiences of Pākehā allyship in psychology

authors: Stolte, Ottilie Emma Elisabeth

abstract: The monocultural foundation of psychology is interwoven with the colonial history of Aotearoa New Zealand. Not all of the mahi of decolonising psychology is the responsibility of Māori. In Aotearoa, there is currently less literature around the development of racial justice allyship and how Pākehā (as the dominant majority) can work towards honouring Te Tiriti o Waitangi. This paper draws on interviews with three Pākehā allies who have taken actions towards greater inclusion of Māori and raising awareness of systemic injustices and racial disparities. The objective of this paper is to document the understandings shared by these ‘reluctant allies’, focusing on the challenges, possibilities, and suggestions for a more culturally relevant psychological education and practice for Aotearoa New Zealand.
