- Ambiguity and the dialogical self: In search for a dialogical psychology.Publication . Ferreira, Tiago; Salgado, João; Cunha, CarlaIt is intuitively felt that ambiguity plays a crucial role in human beings’ everyday life and in psychologists’ theoretical and applied work. However, ambiguity remains essentially non-problematised in psychological science since its foundation. This article analyses positivist and social constructionist perspectives on ambiguity in the context of their epistemological and ontological fundamental assumptions. The relational thesis of social constructionism is further analysed and it is argued that it constitutes a “weak thesis” concerning the relational constitution of human beings. In the second part, a dialogical alternative is elaborated. In this perspective, ambiguity is placed in the context of relationship and both are brought to an ontological ground. Therefore, it is argued, ambiguity is a fundamental property of human experience and plays a fundamental role in the consti tution of (inter)subjective processes. The impact of this thesis on dialogical perspective on self is elaborated.
- Re-autoria, imaginação e mudança.Publication . Gonçalves, M. M.; Cunha, C.Neste texto pretende-se enfatizar o papel determinante que a imaginação ocupa no uso da metáfora narrativa em psicoterapia, na medida em que permite a emergência da diferença necessária para a mudança discursiva. Assim, propõe-se que a terapia narrativa de re-autoria, na versão desenvolvida por White e Epston (1990), intencionaliza o uso da imaginação como ferramenta terapêutica essencial para atingir os seus objectivos. A nossa centração na imaginação prende-se com a convicção de que a capacidade do terapeuta e dos clientes imaginarem possibilidades alternativas na vida das pessoas é mais distintiva da terapia narrativa, do que o uso de qualquer estratégia terapêutica ou prática discursiva específicas (como a externalização). Desta forma, o objectivo do presente artigo é convidar e encorajar os terapeutas desta abordagem a libertarem-se das narrativas dominantes quanto à forma “correcta” de fazer terapia narrativa.

- Saturation in Autoregressive ModelsPublication . Santos, Carlos; Hendry, DavidIn this paper, we extend the impulse saturation algorithm to a class of dynamic models. We show that the procedure is still correctly sized for stationary AR(1) processes, independently of the number of splits used for sample partitions. We derive theoretical power when there is an additive outlier in the data, and present simulation evidence showing good empirical rejection frequencies against such an alternative. Extensive Monte Carlo evidence is presented to document that the procedure has good power against a level shift in the last rT% of the sample observations. This result does not depend on the level of serial correlation of the data and does not require the use of a (mis-specified) location-scale model, thus opening the door to an automatic class of break tests that could outperform those of the Bai-Perron type
