In the age of screens, families are spending more time “alone-together”
Killian Mullan from Oxford University and Stella Chatzitheochari from the University of Warwick looked at time-use data from a nationally representative UK sample of around 5,000 children and their parents.
Use of Mobile Devices Doesn't Reduce Family Time At Home, Study Finds
The Independent online
Dr Stella Chatzitheochari, from the department of sociology at the University of Warwick, explains that the study indicates how use of digital devices has become "embedded into family life".
Disabled children 'more likely to be bullied'
BBC News online
Stella Chatzitheochari, one of the study's authors, said: "We know that being bullied contributes to social inequalities later in life - people who were victims in childhood often grow up to have low self-esteem, anxiety and depression, and perform less well in the labour market than their peers.
"These findings suggest that bullying reinforces the inequalities experienced by disabled people, putting them at a double disadvantage"...

The past decade has witnessed an unprecedented diffusion of mobile devices such as smartphones and tablets in advanced economies, alongside the arrival of powerful Internet connections. According to research by the Pew Research Center, approximately three quarters of American adults own a smartphone (Poushter, 2016), with one in four reporting going online “constantly,” and 43% several times a day (Perrin & Jiang, 2018).
Childhood disability has been largely overlooked in social stratification and life course research. As a result, we know remarkably little about mechanisms behind well‐documented disability differentials in educational outcomes. This study investigates educational transitions of disabled youth using data from the Longitudinal Study of Young People in England. We draw on social stratification literature on primary and secondary effects as well as that on stigma and labelling in order to explain disabled young people's educational outcomes. We find that disability differentials in transition rates to full‐time academic upper secondary education and to university are largely the result of primary effects, reflected in differences in school performance between disabled and non‐disabled young people. However, we also find evidence for secondary effects, with similarly achieving disabled young people less likely to pursue full‐time academic upper secondary education compared to their non‐disabled peers. We examine the extent to which these effects can be explained by disabled youth's suppressed educational expectations as well as their experiences of being bullied at school, which we link to the stigma experienced by disabled young people and their families. We find that educational expectations play an important role at crucial transitions in the English school system, while the effect of bullying is considerably smaller. By drawing attention to different social processes contributing to disability differentials in attainment, our study moves beyond medical models that implicitly assume a naturalized association of disability with poor educational outcomes, and demonstrates the parallels of disability with other ascriptive inequalities.
Recent years have witnessed a steady growth of time-use research, driven by the increased research and policy interest in population activity patterns and their associations with long-term outcomes. There is recent interest in moving beyond traditional paper-administered time diaries to use new technologies for data collection in order to reduce respondent burden and administration costs, and to improve data quality. This paper presents two novel diary instruments that were employed by a large-scale multi-disciplinary cohort study in order to obtain information on the time allocation of adolescents in the United Kingdom. A web-administered diary and a smartphone app were created, and a mixed-mode data collection approach was followed: cohort members were asked to choose between these two modes, and those who were unable or refused to use the web/app modes were offered a paper diary. Using data from a pilot survey of 86 participants, we examine diary data quality indicators across the three modes. Results suggest that the web and app modes yield an overall better time diary data quality than the paper mode, with a higher proportion of diaries with complete activity and contextual information. Results also show that the web and app modes yield a comparable number of activity episodes to the paper mode. These results suggest that the use of new technologies can improve diary data quality. Future research using larger samples should systematically investigate selection and measurement effects in mixed-mode time-use survey designs.
Bullying among school-aged children and adolescents is recognised as an important social problem, and the adverse consequences for victims are well established. However, despite growing interest in the socio-demographic profile of victims, there is limited evidence on the relationship between bullying victimisation and childhood disability. This article enhances our understanding of bullying experiences among disabled children in both early and later childhood, drawing on nationally representative longitudinal data from the Millennium Cohort Study and the Longitudinal Study of Young People in England. We model the association of disability measured in two different ways with the probability of being bullied at ages seven and 15, controlling for a wide range of known risk factors that vary with childhood disability. Results reveal an independent association of disability with bullying victimisation, suggesting a potential pathway to cumulative disability-related disadvantage, and drawing attention to the school as a site of reproduction of social inequalities.
Free time, that is, the time that remains at one's own discretion after conducting daily work and personal care activities, has been previously recognized as a ‘primary good’ and an important welfare resource that provides opportunities for participation in social life and leisure. However, recent years have witnessed an increasing preoccupation with the phenomenon of time poverty, drawing attention to the distribution of free time and its relationship to structural and family circumstances. In this article we propose a novel approach to the measurement of time poverty and document its occurrence amongst British workers. In line with previous literature, a conceptualization of time poverty as a relative lack of free time resources vis‐à‐vis other members of the community is adopted. However, unlike previous empirical studies, we investigate the differential configuration of time poverty on weekdays and weekend days, alongside indicators of the quality of free time, taking into account insights from theoretical and empirical work within the field of the sociology of time. Our analysis of the 2000 UK Time Use Survey highlights class and gender inequalities that have been missed by previous measurement approaches and demonstrates that, overall, working women experience multiple and more severe free time constraints, which may constitute an additional barrier for their leisure and social participation.
Despite the recent theoretical focus on the emergence of the Third Age as a period of fulfilment and an ongoing engagement with an active leisure lifestyle, there is a dearth of quantitative studies on how older people spend their time. Few studies of later life capitalise on time-use surveys, which constitute the most widely employed and accurate methodology for collecting data on everyday life. This article analyses data from the 2000 UK Time Use Survey in order to operationalise the concept of the Third Age and test theoretical propositions regarding the irrelevance of social divisions in the formation of an active leisure lifestyle after retirement. The analysis focuses on a subsample of 1615 people over the age of 64. An index of active leisure activities is constructed in order to estimate the proportion of third agers amongst British retirees. Logistic regression models are specified to examine the relative influence of socio-demographic characteristics on the probability of a person being a third ager. Strong effects of structural factors and health are found, which do not support arguments suggesting a minor influence of social context in lifestyle choices after retirement. ‘Active’ ageing appears to be the province of those who are culturally and materially advantaged, and it is the healthy, educated, upper-class and middle-class men that are more likely to engage in a Third Age leisure lifestyle.
Sleep is functional for individual and societal well-being, with partial sleep deprivation associated with adverse health and safety consequences. Surprisingly, sleep is absent from work—life balance debates and has remained largely under-researched by sociologists. This article examines the relationship of insufficient sleep duration with occupational circumstances and family responsibilities, providing a contribution to the examination of the health consequences of working patterns in the UK. We analyse time use data from 2000, focusing on a sub-sample of workers aged 20—60 years (n = 2882). Nested logistic regression modelling is used to identify the segments of the working population getting a short sleep duration that if sustained may have negative health outcomes. An inverse relationship between working hours and sleep duration is found, which is stronger for men than women. Shift work and social class are also significant predictors of short sleep for men.
