This qualitative study examined preadolescent boys’ and girls’ body ideals, and peer and media factors that shape these ideals. Sixty-eight children aged 8–10 participated in semi-structured interviews: 19 boys and 17 girls in individual interviews and 16 boys and 16 girls in eight group interviews. Techniques from grounded theory were used to analyze the data. Findings demonstrated that fitness was an important element of boys’ and girls’ body ideals. For boys the emphasis was on sport, and this was promoted by their peer interactions and the sportsmen they admired. For girls the focus was on looking good, and this was reinforced by their peer conversations, and the actresses and singers they admired. Focus groups further highlighted how peers both reinforced media messages, yet also helped children critique media messages. Implications are discussed for prevention programs that need to be specifically tailored for boys and girls.

This paper describes the use of general practitioner (GP) services and achievement of guideline targets by 285 adults with type 2 diabetes in urban and regional areas of Victoria, Australia. Anthropometric and biomedical measures and responses to a self-administered questionnaire were collected. Findings indicate that almost all participants had visited a GP and had had their hypoglycated haemoglobin (HbA1c) measured in the past 6 months; less than one-third had visited a practice nurse. Fifty per cent achieved a HbA1c target of ≤7.0%; 40%, a total cholesterol ≤4.00 mmol/L; 39%, BP Systolic ≤130 mmHg; 51%, BP Diastolic ≤80 mmHg; 15%, body mass index ≤25 kg/m2; and 34% reported a moderately intense level of physical activity, that is, ≥30 min, 5 days a week. However, 39% of individuals achieved at least two targets and 18% achieved at least three of these guideline targets. Regional participants were more likely to report having a management plan and having visited a practice nurse, but they were less likely to have visited other health professionals. Therefore, a more sustained effort that also includes collaborative care approaches is required to improve the management of diabetes in Australia.

Purpose
The present study tests several competing, explanatory models—dual pathways, escape from awareness, and objectification theory—for the established link between body dissatisfaction and binge eating.
Methods
408 women aged between 18 and 40 years completed a survey designed to assess contributions of proposed mediators (dietary restraint and negative affect from the dual pathway model, self-distraction from the escape from awareness model, and interoceptive deficits from objectification theory) for the body dissatisfaction–binge eating relationship.
Results
Although mediation analyses supported the dual pathway model and objectification theory when tested separately, the dual pathway model most strongly predicted the body dissatisfaction–binge eating relationship. Both model-implied mediators (dietary restraint and negative affect) made significant unique contributions, accounting for roughly one-quarter of the shared variance between body dissatisfaction and binge eating when tested separately from other mediators. Improvements in variance explained were negligible once other proposed mediators were included in a test of models combined.
Conclusions
Collectively, these findings suggest the superiority of the dual pathway model over objectification theory and the escape model, but the remaining unaccounted for covariance suggests need to consider alternative mechanisms that may also account for the relationship between body dissatisfaction and binge eating.

Following acts of violence in major cities, the future of multiculturalism as a philosophy and a state-sponsored policy to promote peace and interdependence in white majority societies seem uncertain. Ethnographic research that explores the lived experience of multiculturalism in shared public spaces, however, offers the possibility to explore emotional stress as well as possibilities for change in culturally diverse cities. Within this literature, however, there is little grounded research that explores Indigenous-ethnic minority relationships. This paper foregrounds and describes a seemingly mundane event such as catching a bus that entangles my body with an Aboriginal woman and a migrant woman from Fiji in Darwin, Australia. The paper demonstrates how injury, anger, shame and discomfort unfolds when bodies of colour are sites of stress. I explore the emergence of this bodily stress that has outcomes for the capacity of racially differentiated bodies of colour to respond ethically in encounters with strangers. I argue that thick descriptions of events, conceptualisations of agency as distributed and broader understandings of the social have the potential to contribute to anti-racist agendas in Euro-colonial societies with separate Indigenous and multicultural policy frameworks in ways that do not require bodies to 'accumulate' or 'inhabit' whiteness. © 2014 © 2014 Taylor & Francis.

This article examines the effect of early adolescent alcohol use on mid-adolescent school suspension, truancy, commitment, and academic failure in Washington State, United States, and Victoria, Australia. Also of interest was whether associations remain after statistically controlling for other factors known to predict school outcomes.

This study was designed to increase parents' awareness of their role in their preschool child's body image and increase positive body image attitudes. In total, 118 parents (54 intervention, 64 control) of boys aged -3-6 years completed a two-session educational workshop. At post-test and the 3 months' follow-up, parents in the intervention group compared to the control group reported a greater level of perceived knowledge on how they may influence their son's body image and a greater level of body appreciation. These results indicate that educational workshops are effective in improving parents' knowledge to improve their son's body image.

Gastrointestinal nematodes limit the growth, production and welfare of goats but there are few reliable sources of information for recommending management practices across flocks. The effects of animal species (Angora goat, Merino sheep, mixed-grazed goats and mixed-grazed sheep at the ratio of 1:1) and stocking rate (SR: 7.5, 10, 12.5 animals/ha) on gastrointestinal parasitism were determined in a replicated experiment on improved annual temperate pastures in southern Australia, from 1981 to 1984. Detailed monitoring of gastrointestinal nematodes was undertaken on animals before, during (five times per year) and at the conclusion of studies using faecal strongyle egg counts (WEC) and total worm counts. Sheep had a greater proportion of nematodes as Teladorsagia spp. and goats a greater incidence of Trichostrongylus spp. Both goats and sheep developed resistance to Nematodirus spp. during the experiment. WEC was similar in goats and sheep at the start of the experimental period but, thereafter, was consistently greater in goats than in sheep. While WEC was highly related to total worm count, the regressions for sheep and goats were different. Increasing the SR increased the WEC of goats and mixed-grazed goats but not of sheep. During the experiment, WEC declined at 7 and 10 animals/ha but increased at 12.5/ha. Mixed grazing with goats provided beneficial effects for sheep at all stocking rates, but the effects for goats were dependent on the stocking rate, being beneficial at 7.5 and 10/ha but harmful at 12.5/ha. The WEC of separately grazed goats were generally higher than the WEC of mixed grazed goats. The WEC of mixed sheep were lower than those of separately grazed sheep. During the experiment, the WEC of mixed grazed sheep declined faster than the WEC of separately grazed sheep but the WEC of separately grazed goats at 12.5/ha and of mixed grazed goats at 10 and 12.5/ha increased. Under the environmental and pastoral conditions examined, Angora wether goats should not be grazed at SR above those recommended for wether sheep. In the present study, the impact of gastrointestinal-nematode infections in goats was reduced at lower SR. Further, mixed grazing of Angora wether goats with wether sheep at or below the recommended SR resulted in reduced gastrointestinal parasitism for both sheep and goats, compared with monospecific grazing conditions. Goats did not represent a gastrointestinal-nematode hazard to sheep. © 2014 CSIRO.

Aim: The aim of the present study was to examine migration- and socioeconomic-related influences on obesity among African migrant adolescents in Melbourne, Australia. Methods: Anthropometric data were collected from 99 parents and 100 adolescent offspring who also completed questionnaires eliciting demographic, socioeconomic and migration data. Multiple linear regressions were used to assess the relationship between migration- and socioeconomic-related factors and adolescent body mass index (BMI). Results: Only gender and parental BMI were associated with adolescent BMI after adjusting for adolescent age, adolescent gender, religion, parental BMI, parental education level and annual income. Boys (β=-1.45; P < 0.05) had lower BMI than girls. Parental and adolescent BMI were positively associated (β = 0.11; P < 0.05). In examining migration-related factors and adolescent BMI, after adjusting for gender and parental BMI, parental acculturation patterns and pre-migration life environment were associated with adolescent BMI, explaining, respectively, 6.5 and 4.0% of the variance in BMI. An integrated parental acculturation pattern was negatively associated with adolescent BMI (β=-0.17; P < 0.05) while adolescents whose parents came from rural areas had a higher BMI (β = 1.48; P < 0.05) than those whose parents came from urban areas. Adolescent acculturation patterns and length of stay in Australia were non-significantly associated with their BMI. Conclusions: Gender, pre-migration life environment and parental acculturation patterns seem to influence the prevalence of overweight and obesity among African migrant adolescents. Culturally competent obesity prevention programmes targeted towards African adolescents should consider these aspects in their design and delivery; however, further research is required to determine their relative contributions to African adolescent obesity in Australia.

The effect of early adolescent alcohol use on antisocial behavior was examined at one- and two-year follow-up in Washington, United States and Victoria, Australia. Each state used the same methods to survey statewide representative samples of students (N = 1,858, 52% female) in 2002 (Grade 7 [G7]), 2003 (Grade 8 [G8]), and 2004 (Grade 9 [G9]). Rates of lifetime, current, frequent, and heavy episodic alcohol use were higher in Victoria than Washington State, whereas rates of five antisocial behaviors were generally comparable across states. After controlling for established risk factors, few associations between alcohol use and antisocial behavior remained, except that G7 current use predicted G8 police arrests and stealing and G9 carrying a weapon and stealing; G7 heavy episodic use predicted G8 and G9 police arrests; and G7 lifetime use predicted G9 carrying a weapon. Hence, risk factors other than alcohol were stronger predictors of antisocial behaviors.

Predators exert strong selection pressures on their prey. Prey would therefore benefit by adjusting their behaviour to the risk of predation, while predators conversely would benefit from adjusting their behaviour to that of their prey. Extravagant ornamentation has evolved to attract mates and/or successfully compete with conspecifics of the same sex to secure high mating success, even if that occurs at a cost of increased risk of predation. Thus, sexually dichromatic species may be more susceptible to predation than sexually monochromatic species, and the presence of compensation is indicative of such species being more vulnerable. If extravagant ornamentation is costly in terms of predation risk, then we should expect sexually dichromatic species to have longer flight initiation distances (FID) than sexually monochromatic species. If ornamentation is acquired as a handicap with only individuals in prime condition being able to display with the smallest viability cost, we should expect sexually dichromatic individuals to have shorter FID than sexually monochromatic individuals. Such differences among individuals should, on an evolutionary time scale, translate into differences in FID being related to differences in sexual dichromatism among species. We investigated the relationship between FID and sexual dichromatism in phylogenetic analyses, while accounting for effects of continent (Australia, North America, and Europe), body mass, the interaction between sexual dichromatism and body mass and the interaction between sexual dichromatism and continent. In an analysis of 447 species we found shorter FID in sexually dichromatic than in sexually monochromatic species (consistent with the handicap hypothesis because sexually dichromatic species took greater risks), especially so at large body size. FID differed among continents and the relative difference in FID between sexually monochromatic and sexually dichromatic species was larger in Europe than in Australia and North America. These differences among continents may be attributed to latitudinal effects of predation. These findings are important for current ideas about the evolution of secondary sexual characters because they imply covarying continental differences in predation, especially for large bodied sexually dichromatic species.

Sexual size dimorphism is widespread throughout seabird taxa and several drivers leading to its evolution have been hypothesised. While the Australasian Gannet (Morus serrator) has previously been considered nominally monomorphic, recent studies have documented sexual segregation in diet and foraging areas, traits often associated with size dimorphism. The present study investigated the sex differences in body mass and structural size of this species at two colonies (Pope's Eye, PE; Point Danger, PD) in northern Bass Strait, south-eastern Australia. Females were found to be 3.1% and 7.3% heavier (2.74 ± 0.03, n = 92; 2.67 ± 0.03 kg, n = 43) than males (2.66 ± 0.03, n = 92; 2.48 ± 0.03 kg, n = 43) at PE and PD, respectively. Females were also larger in wing ulna length (0.8% both colonies) but smaller in bill depth (PE: 2.2%; PD: 1.7%) than males. Despite this dimorphism, a discriminant function provided only mild accuracy in determining sex. A similar degree of dimorphism was also found within breeding pairs, however assortative mating was not apparent at either colony (R2 < 0.04). Using hydrogen isotope dilution, a body condition index was developed from morphometrics to estimate total body fat (TBF) stores, where TBF(%) = 24.43+1.94*(body mass/wing ulna length) - 0.58*tarsus length (r2 = 0.84, n = 15). This index was used to estimate body composition in all sampled individuals. There was no significant difference in TBF(%) between the sexes for any stage of breeding or in any year of the study at either colony suggesting that, despite a greater body mass, females were not in a better condition than males. While the driving mechanism for sexual dimorphism in this species is currently unknown, studies of other Sulids indicate segregation in foraging behaviour, habitat and diet may be a contributing factor.

PURPOSE: There have been few longitudinal studies of deliberate self-harm (DSH) in adolescents. This cross-national longitudinal study outlines risk and protective factors for DSH incidence and persistence. METHODS: Seventh and ninth grade students (average ages 13 and 15 years) were recruited as state-representative cohorts, surveyed, and then followed up 12 months later (N = 3,876), using the same methods in Washington State and Victoria, Australia. The retention rate was 99% in both states at follow-up. A range of risk and protective factors for DSH were examined using multivariate analyses. RESULTS: The prevalence of DSH in the past year was 1.53% in Grade 7 and .91% in Grade 9 for males and 4.12% and 1.34% for Grade 7 and Grade 9 females, respectively, with similar rates across states. In multivariate analyses, incident DSH was lower in Washington State (odds ratio [OR] = .67; 95% confidence interval [CI] = .45-1.00) relative to Victoria 12 months later. Risk factors for incident DSH included being female (OR = 1.93; CI = 1.35-2.76), high depressive symptoms (OR = 3.52; CI = 2.37-5.21), antisocial behavior (OR = 2.42; CI = 1.46-4.00), and lifetime (OR = 1.85; CI = 1.11-3.08) and past month (OR = 2.70; CI = 1.57-4.64) alcohol use relative to never using alcohol. CONCLUSIONS: Much self-harm in adolescents resolves over the course of 12 months. Young people who self-harm have high rates of other health risk behaviors associated with family and peer risks that may all be targets for preventive intervention.

In recent years, academic and public attention has increasingly focused on the issue of men’s preoccupation with body image and the increasing incidence of eating disorders among men. Although most of this focus has been on young and adult males, media discourse has tended to extend explanations for men’s aspirations for social body ideals to explanations for eating disorders in young boys. In this article, we take a critical look at the way the boys/body image/eating disorder nexus has been represented in some of the mainstream media. In particular, we propose that the boys/body image/eating disorder nexus has been constituted as a truth that tends to underplay the complexity of the relationship between eating disorders and boys’ dissatisfaction with their bodies, as recognized by researchers and health practitioners, and as evident from our own study of preteen boys diagnosed with an eating disorder. In this article, we use interviews with the six boys and their mothers collected for our study to construct short family biographies. These

In this paper, I will analyze the history of the image in Murujuga, located in Western Australia, through three stages: creation, preservation and destruction. I will argue that each stage is linked to a turning point in the history of Australia. The first stage is linked to the Dreamtime, a time where Aboriginal cosmology sets the origin of the world. The second stage is linked to the arrival of the white settlers and colonialist practices, where surprisingly the images were neither appropriated nor destroyed, but neglected. The third stage is linked to destruction, where the Aboriginal images from Murujuga does not find a place, and instead are excluded from the multicultural frame of heritage, that Australia boasts. The conclusion will give me the opportunity to discuss how these changes have affected the meaning and perception of these specific images (Aboriginal rock art), by contesting the concept of heritage.
