Migration and development in western Kenya, 1971-82: a retrospective study of primary school leavers

The relationship between socioeconomic development and migration in Kenya during the period 1971-1982 is explored using data from a retrospective survey of school leavers from a small area in Kakamega, Western Province, Kenya. The continuity of migration patterns over time is noted, with a predominance of circular migration and migration to the capital, Nairobi. The data indicate a steady decline in the prosperity of the region. (summary in FRE)     

Multiple Contexts as Cross-classified Models: The Labor Vote in the British General Election of 1992

Voters make their decisions in social and geographical contexts that can be seen as different levels in an overall data structure. Increasingly these structures are being analyzed by multilevel models, but this approach has so far been limited to structures that are strictly hierarchical. This paper outlines the approach of cross-classified multilevel models in which units at lower levels in the structure can be nested in more than one higher-level unit simultaneously. An appropriate modeling framework is outlined, models are specified, and particular attention is paid to efficient computation. The approach is illustrated through a cross-classified logit analysis of Labor versus Conservative support for a nationally representative sample of voting behavior for the 1992 British General Election. The data is structured so that individual voters at level 1 are nested within constituencies at level 2 which are cross-classified by geographical and functional regionalizations at level 3. A conclusion discusses the general utility of a cross-classified approach to geographically based contextual research, while two technical appendices provide details on model estimation.     

Editorial

Similarities in late Middle Cambrian trilobite, inarticulate brachiopod and molluscan faunas are apparent between Bornholm (Denmark) and New Zealand. Tuarangia gravgaerdensis sp. nov. is described from the late Middle Cambrian Andrarum Limestone of Bornholm, Denmark. The Andrarum Limestone is stratigraphically correlated with the Tasman Formation, New Zealand, from where the genus Tuarangia was first described. A single specimen, referred to Tuarangia, has been found in an erratic boulder from NW Poland. The boulder is estimated to be of early Late Cambrian age. The initial taxonomic assignment of Tuarangia to the Bivalvia, Subclass Pteriomorphia, is upheld. The distance between Bornholm and New Zealand, the position at opposite hemispheres, and the palaeogeography in general clearly indicate isocommunities with restricted possibility of exchange of the gene pool at species level.
