Using the Omnibus Survey to test questions on emigration

It is important that migration is measured accurately, for example to inform population estimates and projections. However, current sources of information make it difficult to produce robust estimates of emigration from Great Britain. Several other countries, including Ireland, make use of household surveys in their estimates of migration. To investigate the feasibility of obtaining information on emigration from those resident in Great Britain, three questions were included in the Omnibus Survey for two months. Respondents were asked whether they had plans to emigrate or whether anyone in their family had recently emigrated or intended to shortly. This article reports on the results of this pilot, providing evidence on response levels, comparison with the International Passenger Survey and feedback from interviewers on the questions asked.     

The use of a Quantimet image analysis system to analyse trypsin banding patterns of V79/4 (AH1) Chinese hamster chromosomes

Summary A Quantimet image-analysis system was programmed to identify and print out banding patterns from G-banded chromosome spreads of a clone derived from the established cell line V79/4 (Chinese hamster fibroblasts), designated V79/4(AH1).Acknowledgments.
