Precursors and correlates of anxiety trajectories from late childhood to late adolescence

The present research employed a prospective, multi-informant design to examine precursors and correlates of differing anxiety profiles from late childhood to late adolescence. The sample consisted of 626 boys and 667 girls who are participants in the Australian Temperament Project, a large, longitudinal, community-based study that has followed young people's psychosocial adjustment from infancy to adulthood. The present research analyzes data collected from the first 12 waves of data, from 4–8 months to 17 years. Parents, primary school teachers, maternal and child health nurses, and from the age of 11 onward, the young people themselves have provided survey data. Trajectory analyses revealed three distinct patterns of self-reported anxiety from late childhood to late adolescence, comprising low, moderate, and high (increasing) trajectories, which differed somewhat between boys and girls. A range of parent- and teacher-reported factors was found to be associated with these trajectories, including temperament style, behavior problems, social skills, parenting, negative family events, and peer relationships. Compared with male trajectories, female trajectories were associated with a greater variety of psychosocial variables (including parenting and externalizing problems), which may partially account for the higher prevalence of anxiety in adolescent girls compared with boys. Findings shed light on gender-specific pathways to anxiety and the need for comprehensive, integrative approaches to intervention and prevention programs.

Late

Late (2012) is one of a series of works investigating the relationship between artist and ideas of liminality and location. This work was produced in inland Queensland, and invited to be exhibited as a shortlisted group of artists in the Bayton Awards, for the Rockhampton City Gallery.

Consumption of a low glycaemic index diet in late life extends lifespan of Balb/c mice with differential effects on DNA damage

Background : Caloric restriction is known to extend the lifespan of all organisms in which it has been tested. Consequently, current research is investigating the role of various foods to improve health and lifespan. The role of various diets has received less attention however, and in some cases may have more capacity to improve health and longevity than specific foods alone. We examined the benefits to longevity of a low glycaemic index (GI) diet in aged Balb/c mice and examined markers of oxidative stress and subsequent effects on telomere dynamics.

Results : In an aged population of mice, a low GI diet extended average lifespan by 12%, improved glucose tolerance and had impressive effects on amelioration of oxidative damage to DNA in white blood cells. Telomere length in quadriceps muscle showed no improvement in the dieted group, nor was telomerase reactivated.

Conclusion : The beneficial effects of a low GI diet are evident from the current study and although the impact to telomere dynamics late in life is minimal, we expect that earlier intervention with a low GI diet would provide significant improvement in health and longevity with associated effects to telomere homeostasis.

The effects of the late 2000s global financial crisis on Australia's construction demand

An accurate measurement of the impacts of external shocks on construction demand will enable construction industry policymakers and developers to make allowances for future occurrences and advance the construction industry in a sustainable manner. This paper aims to measurethe dynamic effects of the late 2000s global financial crisis on the level of demand in the Australian construction industry. The vector error correction (VEC) model with intervention indicators is employed to estimate the external impact from the crisis on a macro-level construction economic indicator, namely construction demand. The methodology comprises six main stages to produce appropriate VEC models that describe the characteristics of the underlying process. Research findings suggestthat overall residential and non-residential construction demand were affected significantly by the recent crisis and seasonality. Non-residentialconstruction demand was disrupted more than residential construction demand at the crisis onset. The residential constructionindustry is more reactive and is able to recover faster following the crisis in comparison with the non-residential industry. The VEC model with intervention indicators developed in this study can be used as an experiment for an advanced econometric method. This can be used to analyse the effects of special eventsand factors not only on construction but also on other industries.
