    ABSTRACT: Probabilistic record linkage techniques assign match weights to one or more potential matches for those individual records that cannot be assigned 'unequivocal matches' across data files. Existing methods select the single record having the maximum weight provided that this weight is higher than an assigned threshold. We argue that this procedure, which ignores all information from matches with lower weights and for some individuals assigns no match, is inefficient and may also lead to biases in subsequent analysis of the linked data. We propose that a multiple imputation framework be utilised for data that belong to records that cannot be matched unequivocally. In this way, the information from all potential matches is transferred through to the analysis stage. This procedure allows for the propagation of matching uncertainty through a full modelling process that preserves the data structure. For purposes of statistical modelling, results from a simulation example suggest that a full probabilistic record linkage is unnecessary and that standard multiple imputation will provide unbiased and efficient parameter estimates.

    ABSTRACT: In the spring of 2010, at the University of Bristol, in the Graduate School of Education, we revisited the case of Pierre Rivière's parricide. More than thirty years after Foucault's (1975) publication devoted to this case, and almost two hundred years after the parricide, we took part in various research events that enabled us to re-connect with Pierre Rivière's memoir. One of these events was a fictional ‘definitional ceremony’. Definitional ceremony is a technique normally used in narrative therapy, and was used by Michael White who developed a Foucauldian analysis of the socio-cultural constitution of mental health. For the purposes of our fictional ceremony two doctoral research students (the authors of this paper) ‘borrowed’ the identities of two of the main protagonists in the Pierre Rivière story. They dressed in period costumes, and embarked on a staging that instigated a renegotiation/resignification of their relationship with each other in the present, and in conversation with a narrative therapist. Our purpose was to re-engage with a troubled family of the nineteenth century as an experiment in seeing how research modalities affect not only our research, but ourselves as researchers.

    ABSTRACT: This study drew on data from two different initiatives in which groups of participants were asked to work together to build knowledge. In the first initiative school students were asked to discuss ethical issues in science, using a moderated online discussion board and in the second, researchers in the field of Technology Enhanced Learning (TEL) used a wiki to develop a vision statement. Despite the different contexts and purposes of the initiatives, the outcomes were remarkably similar in terms of a) the extent and patterns of contributions and b) the quality of the contributions. In both, there was some level of success in that the intended outcome was reached. However, in both, there were fewer contributions than anticipated and the quality of a large proportion of the contributions was disappointing. It is suggested that the reasons for this are related to four factors; the socio-cultural setting, the nature of the knowledge that was being built, the tools used and the way the activity was set up (including setting shared goals).
