Evaluating Area‐based Interventions: The Case of ‘Communities for Children’

Increasingly, governments in wealthy countries are designing early intervention initiatives around principles of ‘community regeneration’ or ‘place management’. Because these initiatives are multi‐site, aimed at long‐term systemic change, and implemented amidst a range of other initiatives, assessing their quality and outcomes demands departure from conventional programme evaluation approaches. This article analyses the challenges of evaluating area‐based interventions in the child welfare field, and shows how the National Evaluation of Australia's ‘Communities for Children’ initiative seeks to overcome these through its mixed method design and the longitudinal Stronger Families in Australia study.     

Life Cycle Risks for Human Health: A Comparison of Petroleum Versus Bio-Based Production of Five Bulk Organic Chemicals

This article describes the development and application of a generic approach to the comparative assessment of risks related to the production of organic chemicals by petrochemical processes versus white biotechnology. White biotechnology, also referred to as industrial biotechnology, typically uses bio-based feedstocks instead of the fossil raw materials used in the petrochemical sector. The purpose of this study was to investigate whether the production of chemicals by means of white biotechnology has lower conventional risks than their production by petrochemical processes. Conventional risks are the risks of well-established processes, and not those related to genetically modified microorganisms and plants. Our approach combines classical risk assessment methods (largely based on toxicology), as developed by the life cycle assessment (LCA) community, with statistics on technological disasters, accidents, and work-related illnesses. Moreover, it covers the total process chain for both petrochemical and bio-based products from cradle to grave. The approach was applied to five products: the plastics polytrimethylene terephthalate (PTT), polyhydroxyalkanoates (PHA), polyethylene terephthalate (PET), polyethylene (PE), and ethanol. Our results show that the conventional risks related to the white biotechnology products studied are lower than those of the petrochemical products. However, considering the uncertainties with respect to the ranges of input data, the (incomplete) coverage of emissions by the environmental priority strategies (EPS) 2000 method, and the uncertainties of the assumptions made in this study (i.e., large to very large), the differences in results between bio-based and petrochemical products fall into the uncertainty range. Because of this, future research is necessary to decrease the uncertainties before we can conclude that the conventional risks of biotechnologically produced chemicals are lower than those of fossil-fuel-derived chemicals.     

‘The past was never simply there to begin with and the future is not simply what will unfold’: a posthumanist performative approach to qualitative longitudinal research

In this article I argue that in their current genealogical and philosophical configuration, qualitative longitudinal research (QLR) practices – and a wider regime of knowledge, ethical, moral, legal, technological, political and economic practices with which they are entangled – embed and enact representational assumptions in which the realities being investigated – time, change and continuity; the past, present and future – are taken as ontologically given and independent of these QLR (and wider) practices. My approach is to conceptualize QLR practices along nonrepresentational lines, through a philosophical framework that is able to materialize the constitutive effects of QLR (and wider) practices on the objects of study and knowledges produced. For this, I turn to Karen Barad’s posthumanist performative metaphysics – ‘agential realism’ – a framework that embodies and enacts a non-classical ontology in which entities are seen as constituted through material-discursive practices. On this account, QLR (and wider) practices are understood as an ineliminable and constitutive part of the realities they help bring into being.     

Benefits to Children Who Participate in Family Therapy with their Substance‐Using Mother

It is rare that family members other than the identified patient are followed over time in studies of therapy effectiveness. Family therapy is believed to be effective because it targets processes within the system that maintain symptoms. If these processes are changed, then all family members can benefit. Using a sample of 183 mother–child dyads from a study comparing family therapy for adult substance use versus an attention control, change in child's substance use (tobacco, alcohol, and marijuana) was estimated. Children who participated in family therapy with their mothers showed greater decreases in alcohol and tobacco use and were less likely to begin using compared to children whose mothers participated in the attention control condition.     

Trajectories of low-income mothers’ and fathers’ engagement in learning activities and child socioemotional skills in middle childhood

Using Fragile Families and Child Wellbeing data (N = 3259), the current study examined Black and Latinx mothers’ and fathers’ trajectories of engagement in learning activities (e.g., storytelling) from infancy to age 5, and whether those trajectories predicted socioemotional skills at age 9, predictors of the trajectories (poverty, mother-father nonresidence, temperament, race/ethnicity), and moderators of the trajectories. Mothers’ and fathers’ learning activities decreased significantly over time as children got older. Higher rates of decline in fathers’ engagement in learning activities over time significantly predicted lower socioemotional skills. Mother-father nonresidence during infancy was associated significantly with higher rates of decline in mothers’ and fathers’ learning activities. Difficult temperament moderated the association between fathers’ trajectories and child outcomes.     

Adolescents’ perceptions of social risk and prosocial tendencies: Developmental change and individual differences

Many prosocial behaviors involve social risks such as speaking out against a popular opinion, bias, group norm, or authority. However, little is known about whether adolescents’ prosocial tendencies develop over time with their perceptions of social risks. This accelerated longitudinal study used within-subject growth-curve analyses to test the link between adolescents' prosocial tendencies and social risk perceptions. Adolescents completed self-reports annually for 3 years (N = 893; M_age = 12.30 years, 10–14 years at Wave 1, and 10–17 years across the full study period; 50% girls, 33% White non-Latinx, 27% Latinx, 20% African American, 20% mixed/other race). The association between social risk tolerance and prosocial tendencies changed significantly across adolescence. Specifically, for younger adolescents, more prosocial tendencies were associated significantly with less social risk tolerance, whereas for relatively older adolescents, more prosocial tendencies were associated marginally with more social risk tolerance. Additional individual differences by empathy (but not sensation seeking) emerged. These findings suggest that prosocial tendencies across adolescence may be associated with an underlying ability to tolerate social risks.     

Substance Abusing Mothers with a History of Childhood Abuse and Their Children's Depressive Symptoms: The Efficacy of Family Therapy

This study examined the associations among maternal history of childhood abuse, substance use, and depressive symptoms and the change in children's depressive symptoms in therapy. Mothers (N = 183) were randomly assigned into either a family or an individual treatment condition. Mothers were assessed for their childhood abuse retrospectively, baseline depressive symptoms, and substance use, whereas their children's depressive symptoms were measured five times during 1.5 years. Maternal childhood abuse was associated with a slower decline in child depressive symptoms through elevated maternal depressive symptoms, only in individual treatment. Maternal substance use further moderated this mediation pathway. This study supports the efficacy of family therapy in protecting children of mothers with a substance use disorder and a history of childhood abuse.
