renegotiation of access, with a particular emphasis on the ways in which past interactions in the research have been valued and used towards developing sociological accounts for policy and academic audiences. Secondly, the ways in which relationships are maintained between funded research activity. Thirdly, the on-going dialogue and development of informed consent as this longitudinal research maintains a broad research area, but considers different research questions and outcomes, in each stage of the research. Particular attention will be given to how this dialogue is managed to avoid attrition of individuals and groups to the research. Fourthly, consideration will be given to the ways in which data may be lost to the research as events in participants lives recast the ways in which they want to present themselves in the present to the researchers and the research. Finally, this paper will consider the cumulative effect of sampling in qualitative longitudinal research. The opportunities afforded to research through sampling additional participants (sometimes referred to as boosting the sample), and the potential value afforded through sampling dynamic social phenomena through extended periods of time.
