Abstract With few exceptions, spatial estimation of rainfall typically relies on information in the spatial domain only. In this paper, a method that utilizes information in time and space and provides an assessment of estimate uncertainty is used to create a gridded monthly rainfall dataset for the United Kingdom over the period 1980–87. Observed rainfall profiles within the region were regarded as the sum of a deterministic temporal trend and a stochastic residual component. The parameters of the temporal trend components established at the rain gauges were interpolated in space, accounting for their auto- and cross correlation, and for relationships with ancillary spatial variables. Stochastic Gaussian simulation was then employed to generate alternative realizations of the spatiotemporal residual component, which were added to the estimated trend component to yield realizations of rainfall (after distributional corrections). In total, 40 realizations of rainfall were generated for each month of the 8-yr period. The methodology resulted in reasonably accurate estimates of rainfall but underestimated in northwest and north Scotland and northwest England. The cause for the underestimation was identified as a weak relationship between local rainfall and the spatial area average rainfall, used to estimate the temporal trend model in these regions, and suggestions were made for improvement. The strengths of this method are the utilization of information from the time and space domain, and the assessment of spatial uncertainty in the estimated rainfall values.

This paper begins with two observations: that UK homes appear to have accumulated increasing numbers of domestic technologies, yet new houses are smaller, on average, than those built before 1980. The spatial pressures placed on homes that result from the accumulation of technologies are explored by drawing upon forty household interviews which enquired into the domestic organisation of kitchen and bathroom technologies and practices. Many households have responded to such spatial pressures by extending or reformulating their domestic spaces: such that kitchens are becoming increasingly multifunctional spaces and bathrooms are multiplying. It is argued that these trends are not simply driven by an unstoppable tide of material possession but reflect context-specific arrangements related to the temporal and ideological structuring of domestic practices. Technologies and practices coevolve with the result that new demands are made on homes—the commodities and objects with which we live our lives influence our experience of space and the value placed on different physical configurations. Domestic technologies are therefore implicated in the structure and reproduction of practice and hence in the choreography of things and people in time and space.

The collection of data about the identity characteristics of library users is the latest development in a long history of contested categorisation practices. In this article, I highlight how the collection of data about lesbian, gay, bisexual, trans and queer (LGBTQ) people has implications for the undertaking of diversity monitoring exercises in academic and public libraries. Based on experiences in the United Kingdom, I argue that recuperative efforts to ‘fix’ categorisation practices are not enough and overlook how categories of gender, sex and sexuality are constructed through the practice of diversity monitoring, how categories are positioned in time and space, and who is involved in decision-making about who to include and exclude from the category of ‘LGBTQ’.

Legal geographers have recently highlighted the importance of attending to the interaction of time and space to understand law and its enactment. We build on these efforts to examine the spatiotemporal influences over the processes by which asylum claim determination procedures in Western industrialised countries seek to reconstruct past events for the purposes of deciding refugee claims. Two ‘common-sense’ beliefs underpin this reconstruction: that the occurrences leading to a fear of persecution can be isolated and that the veracity of an asylum claim is objectively independent from the process of uncovering it. We critically interrogate these assumptions by conceptualising the fears of people seeking asylum as Deleuzian ‘events’. Basing our argument on 41 interviews with people who have previously claimed asylum in the United Kingdom and firsthand accounts of asylum appeals, we explore the folding together of asylum ‘truths’ and the spatiotemporal processes by which they are arrived at, arguing that refused asylum claims are not simply detected by the process – they are produced by it.
