Increase In Caesarean Deliveries After The Australian Private Health Insurance Incentive Policy Reforms, Kristjana Einarsdottir, Anna Kemp, Fatima Haggar, Rachael Moorin, Anthony Gunnell, David Preen, Fiona Stanley, C. D'Arcy Holman

Background: The Australian Private Health Insurance Incentive (PHII) policy reforms implemented in 1997–2000 increased PHI membership in Australia by 50%. Given the higher rate of obstetric interventions in privately insured patients, the reforms may have led to an increase in surgical deliveries and deliveries with longer hospital stays. We aimed to investigate the effect of the PHII policy introduction on birth characteristics in Western Australia (WA). Methods and Findings: All 230,276 birth admissions from January 1995 to March 2004 were identified from administrative birth and hospital data-systems held by the WA Department of Health. Average quarterly birth rates after the …

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert Davis, C Gole, Jd Roberts

Research outputs 2012

Urban development either eliminates, or severely fragments, native vegetation, and therefore alters the distribution and abundance of species that depend on it for habitat. We assessed the impact of urban development on bird communities at 121 sites in and around Perth, Western Australia. Based on data from community surveys, at least 83 % of 65 landbirds were found to be dependent, in some way, on the presence of native vegetation. For three groups of species defined by specific patterns of habitat use (bushland birds), there were sufficient data to show that species occurrences declined as the landscape changed from variegated …


Problem Behaviours, Traditional Bullying And Cyberbullying Among Adolescents: Longitudinal Analyses, Leanne Lester, Donna Cross, Therese Shaw Jan 2012

Problem Behaviours, Traditional Bullying And Cyberbullying Among Adolescents: Longitudinal Analyses, Leanne Lester, Donna Cross, Therese Shaw

Research outputs 2012

Problem Behaviour Theory suggests that young people's problem behaviours tend to cluster. This study examined the relationship between traditional bullying, cyberbullying and engagement in problem behaviours using longitudinal data from approximately 1500 students. Levels of traditional victimisation and perpetration at the beginning of secondary school (grade 8, age 12) predicted levels of engagement in problem behaviours at the end of grade 9 (age 14). Levels of victimisation and perpetration were found to moderate each other's associations with engagement in problem behaviours. Cyberbullying did not represent an independent risk factor over and above levels of traditional victimisation and perpetration for higher …


Adolescent Bully-Victims: Social Health And The Transition To Secondary School, Leanne Lester, Donna Cross, Therese Shaw, Julian Dooley Jan 2012

Adolescent Bully-Victims: Social Health And The Transition To Secondary School, Leanne Lester, Donna Cross, Therese Shaw, Julian Dooley

Research outputs 2012

This study aimed to investigate the causal pathways and factors associated with being involved in bullying behaviour as a bully-victim using longitudinal data from students aged 11-14 years over the transition time from primary to secondary school. Examination of bully-victim pathways suggest a critical time to intervene is prior to transition from the end of primary school to the beginning of secondary school to prevent and reduce the harm from bullying. Negative outcome expectancies from bullying perpetration were a significant predictor of being a bully-victim at the end of the first year of secondary school. The findings show an association …


Developmental Trajectories Of Adolescent Victimization: Predictors And Outcomes, Leanne Lester, Donna Cross, Julian Dooley, Therese Shaw Jan 2012

Developmental Trajectories Of Adolescent Victimization: Predictors And Outcomes, Leanne Lester, Donna Cross, Julian Dooley, Therese Shaw

Research outputs 2012

Chronic victimization negatively affects mental health, making it crucial to understand the key predictive social health (e.g., loneliness, isolation) factors. Evidence suggests that the effects of victimization are worse over the transition from primary to secondary school. Longitudinal data from 1810 students transitioning were used to identify victimization trajectory groups, classified as low increasing, low stable, medium stable, and not bullied. Adolescents with poorer social health were more likely to be in the increasing and stable victimized group than in the not bullied group. Students in the low increasing victimized group had poorer mental health outcomes than those in the …
