Arts participation and the three faces of time: A reflection on disentangling the impact of life stage,period and socialization on arts participation,exemplified by an analysis of the US arts audience

Arts participation bears the threefold imprint of time: people's life stage (age), their earlier socializing imprint (cohort) and the historical circumstances of the moment (period). A proper understanding of these three effects is of great importance in understanding the present and future sizes and preferences of arts audiences. Such understanding implies disentangling those three effects properly, rather than overlooking or confusing them. An example of how that might be done is presented here with regard to arts participation in the US.     

The impact of child maltreatment on the risk of deliberate self-harm among adolescents: A population-wide cohort study using linked administrative records

Adolescents exposed to maltreatment have an elevated risk of deliberate self-harm (DSH). The aim of this study was to investigate longitudinally the effects of the number, timing, and type of maltreatment allegations on adolescent risk of having a DSH-related hospital admission, using linked data in Western Australia. A total of 351,372 children born between 1986 and 2000 were followed from birth up to the year 2010. Cox regression models were utilized, while controlling for a range of psychosocial covariates. Compared to children without allegations of maltreatment, children with unsubstantiated allegations only (aHR = 1.04, 95%CI: 1.00–1.08, p < .01) and children with a substantiated allegation (aHR = 1.10, 95%CI: 1.06–1.15, p < .001) all had significantly increased risk of DSH in adolescence. Among children with a substantiated allegation of maltreatment, the greater the number of allegations, the longer the exposure to maltreatment, and the more types of maltreatment experienced by a child, the higher the child's risk of DSH. However, this dose–response pattern was not found among children with unsubstantiated allegations only. This study calls for the early identification of children who are vulnerable to maltreatment, the better identification of the duration and severity of maltreatment experiences, and the provision of continued care and support, to reduce the child's DSH risk in adolescence.     

Childhood maltreatment and high dietary fat intake behaviors in adulthood: A birth cohort study

Childhood maltreatment has been associated with a wide range of chronic medical conditions including obesity, other metabolic events and eating disorders. However, little is known about the association between childhood maltreatment and high dietary fat intake. This study addresses the extent to which co-occurring and specific forms of substantiated childhood maltreatment are associated with self-reported high dietary fat intake in adulthood and whether there is a gender–childhood maltreatment interaction in predicting this association. The study also examines the association between age at substantiation of maltreatment, number of childhood maltreatment substantiations and high dietary fat intake-related behaviors. The data were from a prospective Australian pre-birth mother-child dyads study, the Mater-University of Queensland Study of Pregnancy. The study followed 7223 mother-child dyads following the birth of a live, singleton baby at the Mater hospital. Recruitment was early in pregnancy, and then follow-ups at 3–5 days postpartum and again when the child was 6 months, 5, 14 and 21 years of age. The data were linked to agency-substantiated cases of childhood maltreatment 0–14 years. This study extended the data linkage to 3766 (47.4% female) participants who had complete data on dietary fat intake behaviors at the 21-year follow-up. Consecutive logistic regressions were used to estimate odds ratios with respective 95% confidence intervals for high dietary fat intake for multiple and specific forms of childhood maltreatment, as well as age at and number of childhood maltreatment substantiations. Finally, a gender–childhood maltreatment interaction term was used to predict the outcome. In both unadjusted and adjusted analyses, substantiated childhood maltreatment including physical abuse were associated with high dietary fat intake-related behaviors. Similarly, substantiation of childhood maltreatment between the ages of 5 and 14 years was significantly associated with high dietary fat intake-related behaviors as were two or more substantiations of maltreatment. Inclusion of gender–childhood maltreatment interaction only had a minor impact on the size and direction of the association. Chronic and severe forms of childhood maltreatment including physical abuse are associated with a higher rate of dietary fat intake in young adulthood. Further research to replicate this association might focus on possible neuro-hormonal mechanisms that might explain this behavior.     

Comparing three South African student cohorts on their attitudes to the rights of working women

This study compares three cohorts (1998–1999, 2005–2006 and 2010) of undergraduate psychology students at a South African university on the level of support for working women (women in paid employment) on various issues considered to be feminist. Cohort 1 (n?=?244), cohort 2 (n?=?311) and cohort 3 (n?=?266) completed an adapted version of a questionnaire used by the Research Group on Women and Work (Kitch, S. L. 1994. “‘We're All in this Alone’: Career Women's Attitudes Toward Feminism.” In Women and Careers: Issues and Challenges, edited by C. W. Konek and S. L. Kitch. London: Sage). The expected liberalisation of attitudes over the cohorts was evident for the females but not for the males: the second male cohort had more conservative attitudes than the first and third male cohorts. While there appeared to be strong overall support for gender equality in work and educational fields, there were equally solid endorsements of the importance of marriage and motherhood for working women. Across the cohorts there were somewhat moderate attitudes on the need for structural change in the family and at work. The implications of the findings are considered.     

The Philosophical Aspects of IRT Equating: Modeling Drift to Evaluate Cohort Growth in Large‐Scale Assessments

Calibration and equating is the quintessential necessity for most large‐scale educational assessments. However, there are instances when no consideration is given to the equating process in terms of context and substantive realization, and the methods used in its execution. In the view of the authors, equating is not merely an exhibit of the statistical methodology, but it is also a reflection of the thought process undertaken in its execution. For example, there is hardly any discussion in literature of the ideological differences in the selection of an equating method. Furthermore, there is little evidence of modeling cohort growth through an identification and use of construct‐relevant linking items’ drift, using the common item nonequivalent group equating design. In this article, the authors philosophically justify the use of Huynh's statistical method for the identification of construct‐relevant outliers in the linking pool. The article also dispels the perception of scale instability associated with the inclusion of construct‐relevant outliers in the linking item pool and concludes that an appreciation of the rationale used in the selection of the equating method, together with the use of linking items in modeling cohort growth, can be beneficial to the practitioners.     

A re‐consideration of rates of ‘social mobility’ in Britain: or why research impact is not always a good thing

This paper re‐considers some of the evidence for low and declining social mobility in Britain, showing that one study based on a re‐analysis of cohort figures appears to have had an impact on policy‐makers out of all proportion to its scale and rigour. The study claimed to show that the income of parents and children were more closely related for sons born in 1970 than in 1958, and that therefore social mobility was declining. It also claimed to show that the incomes of fathers and sons were more closely related in Britain than in countries such as Norway. However, a reconsideration of the same results in this paper leads to very different conclusions. This example is considered in detail here to illustrate the point that it is not always a good thing for research to have influence. The most important and ethical challenge facing social research in education is to improve its quality rather than its impact.     

Child maltreatment and attentional problems: A longitudinal birth cohort study

ObjectiveTo examine whether child maltreatment is associated with attentional problems in adolescence (14 years) and young adulthood (21 years), and whether outcomes depend on the type of maltreatment (sexual vs non-sexual).MethodsData from a population based cohort study involving 3778 mother-child pairs were linked with data from the state child protection agency to examine associations between child abuse and neglect and attention problems, measured using the Achenbach Child Behaviour Checklist (CBCL) and the Achenbach Young Adult Self Report (YASR).Results245 (6.5%) participants had been the subject of notification for non-sexual maltreatment (one or more of neglect, emotional or physical abuse) compared with only 54 (1.4%) who had been subject of notification for suspected sexual abuse. After adjusting for potential confounding variables including maternal, participant and sociodemographic factors, we found those exposed to non sexual maltreatment were likely to experience attentional problems at 14 years (p < .001) and 21 years of age (p = .044), compared with those participants who had not experienced non sexual maltreatment. By contrast, at age 14 years, sexual abuse was associated with attentional problems only as reported by the participant, not their carer. Results at 21 years of age for those exposed to sexual child maltreatment (p=.655) were again in contrast to the observed association between attentional problems and non sexual child maltreatment (p = .035).ConclusionIn this study, non-sexual maltreatment in childhood is associated with attentional problems at both 14 years and 21 years of age. These findings highlight the need for targeted research to better understand the longer term mental health outcomes for children exposed to non-sexual maltreatment. Potential implications for mental health services include the need for broader screening at presentation and importantly, greater collaboration with schools, general practitioners and paediatricians, given the greatest impact would arguably be within these settings.
