In the light of the work of Pierre Bourdieu, this paper begins by reviewing an argument that Western populations no longer recognise any fixed cultural hierarchy and that, instead, individuals seek knowledge of an increasingly wide variety of aesthetically equivalent cultural genres. Contrasting versions of this argument are isolated. Data concerning the frequency of use of different commercial sources of meals and the social characteristics of customers using different types of restaurant in England are examined. An attempt is made to infer the social and symbolic significance of variety of experience and, in particular, of familiarity with diverse ethnic cuisines. The findings are interpreted in terms of the complex role of consumption in personal assurance, communicative competence and social distinction. It is maintained that the pursuit of variety of consumer experience is a feature of particular social groups and that some specific component practices express social distinction.

This paper examines some central themes about change in consumption behaviour through an empirical investigation of the practice of eating. It analyses patterns of food consumption in the UK using time diary data from 1975 and 2000. The practice of eating is decomposed into four component activities which are used to explore systematically the inter-relationships between social processes - such as commodification and temporal fragmentation - and ways of providing and consuming food. It charts the expansion of eating out, the degree to which it substitutes for other eating activities, and the implications of its development for social relations and the temporal organization of daily life. Analysis reveals that food consumption continues to be differentiated along established lines of social division, although the content of those divisions has changed and varies across components of the practice. Increasing commodification of the food chain is documented, but without appearing to have a corrosive impact on household organization or social relationships. While tendencies indicative of temporal fragmentation are revealed, counter-tendencies exist which suggest that the practice of eating is resilient to many forms of external pressure. Finally, the application of a practice-based analytical approach permits critical evaluation of theories of social transformation.

Background Predicting hospital length of stay (LoS) for patients with COVID-19 infection is essential to ensure that adequate bed capacity can be provided without unnecessarily restricting care for patients with other conditions. Here, we demonstrate the utility of three complementary methods for predicting LoS using UK national- and hospital-level data. Method On a national scale, relevant patients were identified from the COVID-19 Hospitalisation in England Surveillance System (CHESS) reports. An Accelerated Failure Time (AFT) survival model and a truncation corrected method (TC), both with underlying Weibull distributions, were fitted to the data to estimate LoS from hospital admission date to an outcome (death or discharge) and from hospital admission date to Intensive Care Unit (ICU) admission date. In a second approach we fit a multi-state (MS) survival model to data directly from the Manchester University NHS Foundation Trust (MFT). We develop a planning tool that uses LoS estimates from these models to predict bed occupancy. Results All methods produced similar overall estimates of LoS for overall hospital stay, given a patient is not admitted to ICU (8.4, 9.1 and 8.0 days for AFT, TC and MS, respectively). Estimates differ more significantly between the local and national level when considering ICU. National estimates for ICU LoS from AFT and TC were 12.4 and 13.4 days, whereas in local data the MS method produced estimates of 18.9 days. Conclusions Given the complexity and partiality of different data sources and the rapidly evolving nature of the COVID-19 pandemic, it is most appropriate to use multiple analysis methods on multiple datasets. The AFT method accounts for censored cases, but does not allow for simultaneous consideration of different outcomes. The TC method does not include censored cases, instead correcting for truncation in the data, but does consider these different outcomes. The MS method can model complex pathways to different outcomes whilst accounting for censoring, but cannot handle non-random case missingness. Overall, we conclude that data-driven modelling approaches of LoS using these methods is useful in epidemic planning and management, and should be considered for widespread adoption throughout healthcare systems internationally where similar data resources exist.

This article examines changes in aspects of the eating habits of the populations of five countries between the early 1970s and the end of the 1990s. Time-use diary data provide the main evidence, which is subjected to techniques of statistical description and regression analysis. The study of France, UK, USA, Norway and the Netherlands shows considerable national variation in patterns of food preparation, eating at home and eating out. Each of these components of the practice of eating is examined for indications of whether there are any tendencies towards dedifferentiation within countries or convergence across countries. There are some common patterns across countries, notably a decline in the amount of time devoted to food preparation. Time spent on eating at home reduces in all countries except France. In the USA, time devoted to domestic food preparation and consumption is minimal. Internal differentiation shows continuities — of gender divisions and age-related behaviour — but also new emergent tendencies — with the presence of children and levels of cultural capital becoming significant predictors of behaviour. It is maintained that the analysis of time-use provides a useful framework for comparing practices in different countries and that the variation revealed might best be understood in terms of different modes of institutionalization of consumption.

Using time diary data to examine practices of reading, this article examines trajectories of change within five countries in the last quarter of the 20th century. It employs a conceptual framework derived from theories of practice to illustrate their application in a quantitative and comparative analysis of change in patterns of consumption. Analysing recruitment and defection, the multiplication and diversification of reading-related practices, and the presence of distinct enthusiast groups leads to the rejection of popular claims that the practice of reading is in decline and that this might be a universal process across societies characterized as having ‘advanced reading cultures’. Critiques of cultural homogenization in the context of global consumer cultures are also corroborated. Also, a conceptual and methodological framework for the application of practice theories to the analysis of consumption and social change is advocated.
