ABSTRACTThis article reviews Alan Wilson's research on population and migration in the 1970s and the 2010s, which supplements his principal contribution - mathematical modelling of urban and regional systems. In the 1970s, drawing on input-output models of economies and working with Philip Rees, Wilson established the accounting basis for Andrei Rogers' multi-regional projection model, adding international migration. Innovative methods were developed to complete demographic accounts, where there were data gaps. In the 2010s, working with Adam Dennett, Wilson systematized methods for estimating migration flows between regions in Europe, employing his family of spatial interaction models. The key aim of both research strands was to ensure that no information was ignored to ensure consistency in population and migration models. The influence of Wilson's contributions to research on population and migration is traced through a survey of subsequent research. 相似文献

As the Covid-19 pandemic continues to unfold around the world, governments engage in diverse decision-making processes that shape everyday living patterns, rituals and livelihoods. This article compares and examines state-level governmental influences on the social construction of the Covid-19 disaster in the United States, specifically analyzing the states of Ohio and Georgia. The authors interrogate how governing bodies and officials in these states differentially construct the crisis and reshape social norms during periods of liminality. 相似文献
