Harry Potter and the Terrors of the Toilet

The Harry Potter series focuses upon the toilet as a site for heroic action and a threshold between worlds as well as a more traditional place for boys to be bullied and girls to weep. This article offers a Kristevan reading of the toilets as abject in Harry Potter, and shows how this concept helps us make sense of wider issues within the series, especially Harry’s uneasy relation to the maternal.

Analysis and behaviour of FRP-confined short concrete columns subjected to eccentric loading

Fibre-reinforced polymer （FRP） composites were widely utilized in civil engineering structures as the retrofit of reinforced concrete （RC） columns. To design FRP jackets safely and economically, the behaviour of such columns should be predicted first. This paper is concerned with the analysis and behaviour of FRP-confined RC circular and rectangular short columns subjected to eccentric loading. A simple design-oriented stress-strain model for FRP-confined concrete in a section analysis was first proposed. The accuracy was then proved by two test data. Following that, a parametric study including amount of FRP confinement, FRP strain capacity, unconfined concrete strength and shape of column section is provided. Some conclusions were obtained at the end of the paper. The work here will provide a comprehensive understanding of the behaviour of FRP-confined concrete columns. The simplicity of the model also enables a simple equivalent stress block to be developed for direct use in practical design.     

Scaling up of Continual Professional Development for Mathematics Problem Solving in Singapore Schools

The more ambitious an educational innovation, the greater the challenge in scaling up. In this paper, we focus on the scaling up of an ambitious pedagogical practice—mathematics problem solving as a regular feature in the classroom. We adopt a long-term approach to continual professional development (CPD) that began with intensive work with one school before we broadened the programme to four other schools which span the spectrum of schools in Singapore. To evaluate this overall design, we examine the current state of each school’s capacity in sustaining mathematics problem-solving instruction. In particular, we study and report findings on these areas: the readiness of teachers, the instructional materials and supporting structures. Based on the findings, we reflect on our CPD strategies and our theory of action which guided the CPD programme.

     

Delay-dependent stochastic stability and H∞ analysis for time-delay systems with Markovian jumping parameters

This paper studies the problem of the stochastic stability and H_∞ disturbance attenuation for linear continuous-time time-delay systems that possess randomly Markovian jumping parameters. A delay-dependent sufficient condition on the stochastic stability with given H_∞ performance is proposed using the stochastic Lyapunov–Krasovskii stability theory. The conditions are formulated as a set of coupled linear matrix inequalities.     

Trajectories of perinatal depressive symptoms in the context of the COVID-19 pandemic

This study sought to advance understanding of the potential long-term consequences of the COVID-19 pandemic for child development by characterizing trajectories of maternal perinatal depression, a common and significant risk factor for adverse child outcomes. Data came from 393 women (86% White, 8% Latina; mean age = 33.51 years) recruited during pregnancy (n = 247; mean gestational age = 22.94 weeks) or during the first year postpartum (n = 146; mean child age = 4.50 months; 55% female). Rates of depression appear elevated, relative to published reports and to a pre-pandemic comparison group (N = 155). This study also provides evidence for subgroups of individuals who differ in their depressive symptom trajectories over the perinatal period. Subgroup membership was related to differences in maternal social support, but not to child birth outcomes.     

Education and psychological distress in adolescence and mid-life: Do private schools make a difference?

This article extends the evidence base on childhood circumstances, education and psychological distress. We examine the link between childhood advantage and disadvantage, the type of school attended during adolescence and psychological distress at ages 16 and 42. The analysis uses a large, population-based birth cohort study, the 1970 British Cohort Study (BCS70) (n = 17,198) using a structural equation modelling (SEM) approach. More advantaged young people were more likely to attend private schools, but we find no evidence for an effect of private schooling on psychological distress for men, and for women there was an association between private schooling and raised psychological distress at age 16. Having a university degree was associated with a modest reduction in psychological distress in mid-life. We establish that maternal psychological distress at age 10 was a risk factor for the offspring’s psychological distress both in adolescence and in mid-life, and adolescent psychological distress predicts psychological distress in mid-life. We conclude that schools which are academically successful do not necessarily provide wider benefits in terms of mental health.     

Visual Chunking Skills of Hong Kong Children

This study investigated the development of visual chunking skills in the processing of Chinese characters among Hong Kong pupils. One-hundred-seventy-nine primary school students from first, second and fourth grades were administered a character copying task. Children as young as 6 years of age were aware of character units and were able to apply visual chunking strategies when processing characters. Children in higher grades performed better than those in lower grades on every character type, and the types of errors they made revealed that their chunking level was higher than that of younger children. Differences between ability groups emerged in second grade and vanished in fourth grade, suggesting that children with a lower reading ability are slower to develop advanced chunking skills.     

African-American women who use crack cocaine: a comparison of mothers who live with and have been separated from their children

OBJECTIVE: This study examined factors that influenced caregiver status for African-American mothers who use crack cocaine but are not receiving drug treatment and participated in an HIV prevention study in North Carolina. METHOD: Caregiver mothers who were living with at least one of their children at intake (n = 257) were compared with non-Caregivers who were separated from all of their children (n = 378). Bivariate analyses and logistic regression were used to compare these mothers at intake on current drug use, risky sex practices, psychological symptoms, victimization, and aggression. RESULTS: Compared with Caregiver mothers, non-Caregivers reported higher frequencies of drug use, risky sex practices, psychological distress, and victimization experiences. Caregiver mothers were more likely than non-Caregiver mothers to have health insurance, but were less likely to have received drug treatment. Logistic regression found that non-Caregiver mothers were significantly more likely than Caregiver mothers to be older, to have been physically abused as children, to trade sex more frequently, to be homeless, and to have no health insurance. Recent crack use, psychological symptoms, and victimization were not significantly related to caregiver status. CONCLUSIONS: Findings that socio-environmental factors were more strongly associated with caregiver status than crack use underscore the importance of contextual issues such as housing, victimization history, and resources in serving maternal crack users. Community outreach and interventions that engage mothers who use drugs and live with their children may be more effective strategies than formal office-based services to link mothers who use crack and their children to needed drug treatment and family and child services.     

Does what you study at age 14–16 matter for educational transitions post-16?

Abstract

This paper considers whether subject choice at 14–16 influences post-16 transitions, taking into account prior academic attainment and school characteristics, and if so, whether this accounts for socioeconomic, gender, and ethnic differences in access to post-16 education. We consider post-16 progression to full-time education, A-levels, and studying two or more facilitating subjects at A-level. We use ‘Next Steps’, a study of 16,000 people born in England in 1989–1990, linked to administrative education records (the National Pupil Database). We find that students pursuing an EBacc-eligible curriculum at 14–16 had a greater probability of progression to all post-16 educational outcomes, while the reverse was true for students taking an applied GCSE subject. Curriculum differences did not explain the social class differences in post-16 progression, but an academic curriculum was equally valuable for working-class as for middle-class pupils. Pursuing an EBacc-eligible curriculum particularly strongly increased the chances of girls and white young people staying in the educational pipeline, whereas applied subjects were particularly detrimental for girls. An EBacc-eligible curriculum at age 14–16 increased the chances of studying subjects preferred by Russell Group universities at A-level.
