Compartimentation et plasticité du réseau microtubulaire

La structuration du cytoplasme repose en grande partie sur le cytosquelette au sein duquel le réseau de microtubules joue de multiples rôles, notamment dans le trafic intracellulaire et la signalisation. Certaines fonctions cellulaires nécessitent des microtubules hautement dynamiques, alors que d’autres utilisent des microtubules stables où la tubuline peut être fortement modifiée. Des données récentes sur les mécanismes de contrôle de la dynamique des microtubules et de leurs modifications post-traductionnelles, notamment de l’acétylation de la tubuline, révèlent la grande plasticité des microtubules et mettent en lumière l’importance de leur compartimentation structurale et fonctionnelle

The power of the interviewer: a qualitative perspective on African survey data collection

BACKGROUND African censuses and surveys remain dependent on interviewers for data collection. Data quality is assured through training and supervision. Many survey concepts are difficult to translate into African languages and some, such as “household”, may have multiple criteria which are not fulfilled by everyone, leading interviewers to prioritise different criteria. Some questions introduce unfamiliar ideas which require considerable negotiation by interviewers to obtain acceptable answers. OBJECTIVE To identify key stages in the data collection process and domains where interviewer judgement and interviewer-respondent social dynamics play a substantial role in determining who is included in household surveys, and in shaping responses to questions. METHODS We analyse published definitions, enumerator manuals and qualitative interview data with households, interviewers, supervisors, trainers, survey organisers and analysts along the chain of data production and use in Tanzania, Uganda, Senegal and Burkina Faso. RESULTS Despite comprehensive training manuals and definitions, interviewers influence who is included and excluded from surveys. Interviewer versatility needs to include both persuasive social skills and an ability to follow precise wording. In Africa, where survey concepts are often different from local concepts and where interviewers are socio-economically distant from respondents, these persuasive social skills are required throughout the interview process with unknown impact on the data produced. Language diversity is a major barrier to harmonisation. CONCLUSIONS To improve survey data validity more effort should be made to understand the influence of interviewers on data in low income settings
