Blur-generated non-separable space–time models

Statistical space–time modelling has traditionally been concerned with separable covariance functions, meaning that the covariance function is a product of a purely temporal function and a purely spatial function. We draw attention to a physical dispersion model which could model phenomena such as the spread of an air pollutant. We show that this model has a non-separable covariance function. The model is well suited to a wide range of realistic problems which will be poorly fitted by separable models. The model operates successively in time: the spatial field at time t +1 is obtained by 'blurring' the field at time t and adding a spatial random field. The model is first introduced at discrete time steps, and the limit is taken as the length of the time steps goes to 0. This gives a consistent continuous model with parameters that are interpretable in continuous space and independent of sampling intervals. Under certain conditions the blurring must be a Gaussian smoothing kernel. We also show that the model is generated by a stochastic differential equation which has been studied by several researchers previously.     

Household Income,Women's Earnings,and Spending on Household Services, 1980–2010

The authors investigated changes in household outsourcing, the practice of spending on services that replace household labor, from 1980 to 2010. During this time, women's labor force participation, increased and economic, household bargaining, and time availability theories predict increased spending during this period. To test these predictions, the authors used data on spending on housekeeping, day care, babysitting and nannies, gardening and lawn services, eating out and pre‐prepared foods from the 1980–2010 Consumer Expenditure Surveys using 327,903 household‐quarters from the interview survey and 86,877 household‐weeks from the diary survey. The results indicate that changes in income predicted increases in housekeeping, child care, and gardening services. Changes in household characteristics predicted little change in food outsourcing, although food outsourcing did increase. Changes in women's earnings predicted little change in most outsourcing. The authors conclude the article with a discussion of the changing context for outsourcing.     

A fractured journey of growth: making meaning of a ‘Broken’ childhood and parental mental ill-health

The psychopathological impact of parental mental ill-health on children is well known. However, little research explores positive and negative interpretations of such exposure in childhood, from the adult child's perspective. Using interpretative phenomenological Analysis this study sought subjective interpretations of the ‘lived’ experiences of growing up in a family with parental mental ill-health. A purposive sample of seven adult children provided data for analysis through semi-structured interviews. One superordinate theme: A fractured journey of growth to adulthood, overarched six subordinate themes. Four themes captured stigma, shame, social isolation and betrayal. Juxtaposed with this, two themes captured purposeful redefinition of self and psychological growth. This study captures the chronicity of traumatic distress and sense of betrayal experienced by these participants in childhood through unrelenting exposure to parental mental ill-health. However, despite unpredictability, fear, and neglect in childhood, they identified the emergence of inner strengths in adult life: unexpected growth in empathy and compassion, high resourcefulness, and personal authenticity through higher education. Findings highlight that positively redefining ‘self’ in adult life is possible in the aftermath of childhood trauma associated with parental mental ill-health. Implications for therapy include: (a) moving forward from childhood trauma and (b) managing ongoing family dynamics in adult-life.     

If You Go Down to the Woods Today: Infants’ Distress During a Teddy Bear's Picnic in Relation to Peer Relations and Later Emotional Problems

Infants’ emotional reactions to an unusual event were assessed at a simulated birthday party during which two costumed characters enacted a Teddy Bear's Picnic. Two hundred and fifty‐eight firstborn infants in a representative British community sample were observed at a mean age of 12.8 months in the presence of their parents and other participating families, in a laboratory sitting room decorated with balloons and banners. The picnic scenario was followed by free play with the other participating infants. At a mean of 36 months of age, mothers, fathers, and another informant who knew the child well completed the Child Behaviour Check List (CBCL). The majority of infants showed no vocal distress during the picnic scenario. A minority of infants expressed strong distress, which was correlated with elevated heart rate and production of cortisol. Infants who were not distressed were more likely to direct social behavior to their peers and especially likely to use physical force against peers. In comparison with strongly distressed and nondistressed infants, those who had shown mild distress during the picnic scenario were least likely to manifest later emotional problems. This pattern was particularly marked for boys. Taken together, the findings indicate that infants’ strong distress during naturalistic encounters that are meant to be entertaining can suppress sociability and might indicate risk for subsequent emotional problems.     

Using Dramaturgy to Better Understand Contemporary Western Tattoos

Spurred on by increasing participation rates, scholarship on tattoos in Western societies has increased noticeably in recent decades. Often focusing on members of the middle class, scholars have assumed that the increasing number of people with tattoos is evidence of mainstream acceptance. In the following article, I critically evaluate claims of tattoo's new mainstream status. Rather than being embraced by the mainstream and power elite, studies and legal proceedings show that tattoos and piercings are only tolerated to a certain degree. I suggest that applying Erving Goffman's dramaturgical approach to contemporary tattoos provides a more complete understanding of tattoo's cultural location. It also allows the focus of the discussion to move beyond the individual attributes and motivations of tattoo wearers and onto the social interactions surrounding them. Moreover, a dramaturgical analysis of tattoos shows the need to properly differentiate between tattoos that are always visible and those that can be concealed. I end by offering a conceptualization of visible tattoos for future sociological research.
