  • Shedding new light on the (in)compatibility of chronic disease management with everyday life – social practice theory, mobile technologies and the interwoven time‐spaces of teenage life

    by Tim Harries, Ruth Rettie, Jonathan Gabe

    This article uses a socio‐material approach, social practice theory, to provide new insights into the self‐management of chronic illness. It demonstrates how this theory can bridge arguments about the respective roles of social and individual influences, and how it can foreground an oft‐overlooked aspect of the issue – the demands of self‐care technologies and consequences for participation in social life. Drawing on interviews and focus groups with 25 young type‐1 diabetes outpatients in London, UK, the study points to the conflicts that occur when disease management technologies compete for time and space with the social practices of everyday life, and when self‐care tasks threaten to interrupt the flow of social life and make people feel ‘left behind’. The paper concludes that young people are disabled by the contingent position of self‐care activities in daily life, which oblige them to compromise either their physical health or their immersion in the social world. This disabling effect would be mitigated if social practices were reorganised to make them more amenable to the time‐space requirements of disease management. A social practice theory lens can help throw light onto this issue and make a valuable contribution to the study of the self‐management of chronic illness.

    Why it takes an ‘ontological shock’ to prompt increases in small firm resilience: Sensemaking, emotions and flood risk

    by Tim Harries, Lindsey McEwen, Amanda Wragg

    This article uses a sensemaking approach to understand small firms’ responses to the threat of external shocks. By analysing semi-structured interviews with owners of flooded small firms, we investigate how owners process flood experiences and explore why such experiences do not consistently lead to the resilient adaptation of premises. We, conclude that some of the explanation for low levels of adaptation relates to a desire to defend existing sensemaking structures and associated identities. Sensemaking structures are only revised if these structures are not critical to business identity, or if a flood constitutes an ‘ontological shock’ and renders untenable existing assumptions regarding long-term business continuity. This article has implications for adaptation to the growing risk of flooding, climate change and external shocks. Future research analysing external shocks would benefit from using a sensemaking approach and survey studies should include measurements of ‘ontological’ impact as well as material and financial damage. In addition, those designing information campaigns should take account of small firms’ resistance to information that threatens their existing sensemaking structures and social identities.


  • Ontological Security and Natural Hazards

    by Tim Harries

    People not only want to be safe from natural hazards; they also want to feel they are safe. Sometimes these two desires pull in different directions, and when they do, this slows the journey to greater physical adaptation and resilience. All people want to feel safe—especially in their own homes. In fact, although not always a place of actual safety, in many cultures “home” is nonetheless idealized as a place of security and repose. The feeling of having a safe home is one part of what is termed ontological security: freedom from existential doubts and the ability to believe that life will continue in much the same way as it always has, without threat to familiar assumptions about time, space, identity, and well-being. By threatening our homes, floods, earthquakes, and similar events disrupt ontological security: they destroy the possessions that support our sense of who we are; they fracture the social structures that provide us with everyday needs such as friendship, play, and affection; they disrupt the routines that give our lives a sense of predictability; and they challenge the myth of our immortality. Such events, therefore, not only cause physical injury and loss; by damaging ontological security, they also cause emotional distress and jeopardize long-term mental health. However, ontological security is undermined not only by the occurrence of hazard events but also by their anticipation. This affects people’s willingness to take steps that would reduce hazard vulnerability. Those who are confident that they can eliminate their exposure to a hazard will usually do so. More commonly, however, the available options come with uncertainty and social/psychological risks: often, the available options only reduce vulnerability, and sometimes people doubt the effectiveness of these options or their ability to choose and implement appropriate measures. In these circumstances, the risk to ontological security that is implied by action can have greater influence than the potential benefits. For example, although installing a floodgate might reduce a business’s flood vulnerability, the business owner might feel that its presence would act as an everyday reminder that the business, and the income derived from it, are not secure. Similarly, bolting furniture to the walls of a home might reduce injuries in the next earthquake, but householders might also anticipate that it would remind them that there is a continual threat to their home. Both of these circumstances describe situations in which the anticipation of future feelings can tap into less conscious anxieties about ontological security. The manner in which people anticipate impacts on ontological security has several implications for preparedness. For example, it suggests that hazard warnings will be counterproductive if they are not accompanied by suggestions of easy, reliable ways of eliminating risk. It also suggests that adaptation measures should be designed not to enhance awareness of the hazard.

    SESAME: Exploring small businesses’ behaviour to enhance resilience to flooding

    by Graham Coates, Nigel Wright, Martina McGuinness, Dabo Guan, Tim Harries, Lindsey McEwen

    In the United Kingdom, small and medium sized enterprises (SMEs) account for approximately 99.9% of businesses, 60% of the working population and 47% annual turnover. However, despite the important contribution that SMEs make to the economy, this size of business remains under-researched with a significant gap in understanding how the disruption caused by flooding impacts on SMEs from the time at which a flood event occurs through to the ‘return’ to normal operations. Business continuity management is a recognised approach for enhancing organisational resilience to major disruptions (ISO 22301, 2012). However, this strategic approach to building such resilience in SMEs is under-explored in the literature with a limited range of empirical data to draw on. This paper presents an overview of an inter-disciplinary research project funded by the UK’s Engineering and Physical Science Research Council, called SESAME, which examines SMEs’ operational response and preparedness to flooding. Furthermore, SESAME consists of four stands of research which bring together a number of disciplines including agent based modelling and simulation, flood modelling, business continuity management, economic modelling and behavioural science. This paper provides an overview of the different research stands within the SESAME project aimed at enhancing SMEs’ resilience to flooding.

    Effectiveness of a smartphone app in increasing physical activity amongst male adults: a randomised controlled trial

    by Tim Harries, Parisa Eslambolchilar, Ruth Rettie, Chris Stride, Simon Walton, Hugo C. van Woerden

    Smartphones are ideal for promoting physical activity in those with little intrinsic motivation for exercise. This study tested three hypotheses: H1 – receipt of social feedback generates higher step-counts than receipt of no feedback; H2 – receipt of social feedback generates higher step-counts than only receiving feedback on one’s own walking; H3 – receipt of feedback on one’s own walking generates higher step-counts than no feedback (H3). A parallel group randomised controlled trial measured the impact of feedback on steps-counts. Healthy male participants (n = 165) aged 18–40 were given phones pre-installed with an app that recorded steps continuously, without the need for user activation. Participants carried these with them as their main phones for a two-week run-in and six-week trial. Randomisation was to three groups: no feedback (control); personal feedback on step-counts; group feedback comparing step-counts against those taken by others in their group. The primary outcome measure, steps per day, was assessed using longitudinal multilevel regression analysis. Control variables included attitude to physical activity and perceived barriers to physical activity. Fifty-five participants were allocated to each group; 152 completed the study and were included in the analysis: n = 49, no feedback; n = 53, individual feedback; n = 50, individual and social feedback. The study provided support for H1 and H3 but not H2. Receipt of either form of feedback explained 7.7 % of between-subject variability in step-count (F = 6.626, p < 0.0005). Compared to the control, the expected step-count for the individual feedback group was 60 % higher (effect on log step-count = 0.474, 95 % CI = 0.166–0.782) and that for the social feedback group, 69 % higher (effect on log step-count = 0.526, 95 % CI = 0.212–0.840). The difference between the two feedback groups (individual vs social feedback) was not statistically significant. Always-on smartphone apps that provide step-counts can increase physical activity in young to early-middle-aged men but the provision of social feedback has no apparent incremental impact. This approach may be particularly suitable for inactive people with low levels of physical activity; it should now be tested with this population.

    Walking as a social practice: dispersed walking and the organisation of everyday practices

    by Tim Harries, Ruth Rettie

    This paper uses social practice theory to study the interweaving of walking into everyday practices and considers how greater awareness of everyday walking can influence its position within the organisation and scheduling of everyday life. Walking is of policy interest because of its perceived benefits for health. This paper asserts that increased awareness of everyday walking allows users to become more active without having to reschedule existing activities. Using Schatzki's distinction between dispersed and integrative practices, it argues that increasing awareness of dispersed walking can enlist walking into the teleoaffective organisation of some social practices and prompt the performance of new ‘health practices’ within everyday domains of life such as shopping and employment. While this analysis offers useful insights for the design of behaviour change strategies, it also points to some unintended consequences of using digital feedback to increase walking awareness. In directing the gaze of participants at one particular element of their daily practices, the paper suggests, digital walking feedback provides a ‘partial’ view of practices: by highlighting the exercise value of walking at the expense of other values it can prompt feedback recipients to pass moral judgements on themselves based on this partial view.A Virtual Abstract of this paper can be found at: https://youtu.be/WV7DUnKD5Mw


  • Energy Consumption Feedback: Engagement by Design

  • Is social norms marketing effective?

    by Tim Harries, Ruth Rettie, Matthew Studley, Kevin Burchell, Simon Chambers

    Purpose: – The purpose of this paper is to present details of a large-scale experiment that evaluated the impact of communicating two types of feedback to householders regarding their domestic electricity consumption: feedback on their own consumption and feedback of both their own consumption and that of others in their locality. Design/methodology/approach: – Digital technologies were used to automatically measure and communicate the electricity consumption of 316 UK residents for a period of 16 weeks. Participants were randomly assigned to one of three experimental conditions: one involving no feedback; one involving feedback about a household's own usage, and one involving a household's own usage plus social norms feedback (the average consumption of others in the locality). At the end of the study, a selection of participants took part in interviews or focus groups. Findings: – Both types of feedback (individual and individual-plus-social-norms) led to reductions in consumption of about 3 per cent. Those receiving social norms feedback were significantly more likely to engage with the information provided. However, the social norms information had no additional impact on consumption. Survey and interview data confirmed that participants from both conditions had been encouraged to adopt new energy-saving practices. The study concludes that near real-time individual feedback can be sufficient for usage reduction if it is provided in a historical format. It also suggests that the impact of social norms information may previously have been confounded with that of individual feedback. Originality/value: – This is the first time that a controlled experiment in the field of domestic electricity consumption has compared the impact of real-time social norm information with that of information that only contains individual household usage.
