Time and emotion in studies of household technologies

In this article I situate studies of household technologies within the overall context of technological studies, in particular in relation to time and the significance of the labour of women in the home. I then discuss the classic studies of household technologies. This perspective was developed mainly in the USA in the 1970s and 1980s. It emphasizes the conservative power of technologies, asserting that they have had no positive impact on housework and home life. I then look at a second emerging perspective of studies of household technologies which shows a model in transition, indicating new patterns of living in families are emerging and that the work of women and men is shifting households and their technologies towards new ways of organizing domestic everyday life. Finally, I explore the connections between these new ways of living and the need for further research in understanding contemporary domestic living with technologies

Adjustment to the Aggregate Association Index to Minimise the Impact of Large Samples

The past few decades have seen a great deal of attention given to the development of techniques to analysis the association between aggregated categorical data. One of the most recent additions to this analysis has been the development of the aggregate association index (AAI). One feature of the AAI is that its magnitude is affected by the sample size; as the sample size increases so too does the AAI, even when the marginal proportions remain unchanged. In this article, we propose adjustments to the AAI to overcome the effect of increasing sample size. The Adjusted AAI is shown to be more stable than the original AAI in response to any increase in the sample size. Fisher's criminal twin data (Fisher, J. R. Stat. Assoc. Ser. A 98, 39-82, 1935) is used to demonstrate the adjustments
