This article aims to open up the biographical black box of three experts working in the boundary zone between science, policy and public debate. A biographical-narrative approach is used to analyse the roles played by the virologists Albert Osterhaus, Roel Coutinho and Jaap Goudsmit in policy and public debate. These figures were among the few leading virologists visibly active in the Netherlands during the revival of infectious diseases in the 1980s. Osterhaus and Coutinho in particular are still the key figures (...) today, as demonstrated during the outbreak of novel influenza A (H1N1). This article studies the various political and communicative challenges and dilemmas encountered by these three virologists, and discusses the way in which, strategically or not, they handled those challenges and dilemmas during the various stages of the field’s recent history. Important in this respect is their pursuit of a public role that is both effective and credible. We will conclude with a reflection on the H1N1 pandemic, and the historical and biographical ties between emerging governance arrangements and the experts involved in the development of such arrangements.

We show how an epistemology informed by cognitive science promises to shed light on an ancient problem in the philosophy of mathematics: the problem of exactness. The problem of exactness arises because geometrical knowledge is thought to concern perfect geometrical forms, whereas the embodiment of such forms in the natural world may be imperfect. There thus arises an apparent mismatch between mathematical concepts and physical reality. We propose that the problem can be solved by emphasizing the ways in which the (...) brain can transform and organize its perceptual intake. It is not necessary for a geometrical form to be perfectly instantiated in order for perception of such a form to be the basis of a geometrical concept. (shrink)

Being diagnosed with cancer can be one of those critical incidents that negatively affect the self. Identity is threatened when physical, psychological, and social consequences of chronic illness begin to erode one’s sense of self and challenge an individual’s ability to continue to present the self he or she prefers to present to others. Based on the notion of illness trajectory and adopting a Ricoeurian narrative perspective, this theoretical paper shall explore the impact of cancer disease on identity and establish (...) the crucial importance of metaphor in the narratives of life with cancer. Findings indicate that in cancer narratives the illness experience supplies the narrative structure with temporal and spatial meeting points that make the narrative comprehensible and meaningful. Cancer forces identity changes not only from having to endure the long-term physical and psychosocial effects of the disease, but also from inevitable existential questions about life’s meaning. Improved medical knowledge today means improved ethnomedical practices. Metaphor can bridge the gap between the cancer experience and the world of technology and treatment, helping patients to symbolically control their illness. (shrink)

Connectionist models aiming to reveal the mechanisms of atypical development must in their undamaged form constitute plausible models of normal development and follow a developmental trajectory that matches empirical data. Constructivist models that adapt their structure to the learning task satisfy this demand. They are therefore more informative in the study of atypical development than the static models employed by Thomas & Karmiloff-Smith (T&K-S).

This article suggests that there are systematic ways in which the identity of the ‘self’, as created and performed through first-person markers, can be made relevant and consequential in particular episodes of interaction. More specifically, the study looks at generalizations that people present about themselves in local interactional contexts: displays of the types of people they are and the ways in which they always or never behave. It will be shown that such self-generalizations are typically used to account for one’s (...) behavior, and that this tendency is tied to the epistemic and moral rights provided by the first-person perspective, having the primary rights to one’s own experience. The study suggests that speakers’ personal characteristics or habitual behavior can be offered as a locally produced micro-identity, which can come to have interactional significance. (shrink)

It is often assumed that similar domain-specific behavioural impairments found in cases of adult brain damage and developmental disorders correspond to similar underlying causes, and can serve as convergent evidence for the modular structure of the normal adult cognitive system. We argue that this correspondence is contingent on an unsupported assumption that atypical development can produce selective deficits while the rest of the system develops normally (Residual Normality), and that this assumption tends to bias data collection in the field. Based (...) on a review of connectionist models of acquired and developmental disorders in the domains of reading and past tense, as well as on new simulations, we explore the computational viability of Residual Normality and the potential role of development in producing behavioural deficits. Simulations demonstrate that damage to a developmental model can produce very different effects depending on whether it occurs prior to or following the training process. Because developmental disorders typically involve damage prior to learning, we conclude that the developmental process is a key component of the explanation of endstate impairments in such disorders. Further simulations demonstrate that in simple connectionist learning systems, the assumption of Residual Normality is undermined by processes of compensation or alteration elsewhere in the system. We outline the precise computational conditions required for Residual Normality to hold in development, and suggest that in many cases it is an unlikely hypothesis. We conclude that in developmental disorders, inferences from behavioural deficits to underlying structure crucially depend on developmental conditions, and that the process of ontogenetic development cannot be ignored in constructing models of developmental disorders. Key Words: Acquired and developmental disorders; connectionist models; modularity; past tense; reading. (shrink)

This study is concerned with the productive aspects of confabulation as it occurs spontaneously in dementia care, in its context, and in interaction with other care recipients. Confabulation is approached as a social and discursive event with distinct narrative features; plots and formerly established genres of plots, storylines, are used by confabulators in order to understand, manage and interact socially in the present situation. Three main functions of confabulation are discerned: 1) making sense of the current situation ; 2) maintaining (...) a personal identity in interaction with others ; and 3) organizing and legitimizing joint action in the world. The resources used by confabulating subjects are sparse and not well adjusted to changing conditions, as the number of accessible storylines is limited. This makes it difficult to apply storylines that explain the current situation satisfactorily, provide useful guidelines for how to act, as well as preserve a positive self-identity. Helping with this constitutes a major challenge in dementia care. (shrink)
