‘Subtypes’ in the presentation of autistic traits in the general adult population

The present study examined the presentation of autistic traits in a large adult population sample (n = 2,343). Cluster analysis indicated two subgroups with clearly distinguishable trait profiles. One group (n = 1,059) reported greater social difficulties and lower detail orientation, while the second group (n = 1,284) reported lesser social difficulties and greater detail orientation. We also report a three-factor solution for the autism-spectrum quotient, with two, related, social-themed factors (Sociability and Mentalising) and a third non-social factor that varied independently (Detail Orientation). These results indicate that different profiles of autistic characteristics tend to occur in the adult nonclinical population. Research into nonclinical variance in autistic features may benefit by considering social- and detail-related trait domains independently.

A chance to bloom: female migration and salvationists in Australia and Canada, 1890s to 1939

Migration is usually analysed as a function of state policy of sending and receiving countries in the context of global movements of people. Thus, despite their sponsorship and support of thousands of migrants, independent, voluntary, religious and ethnic organisations have often been marginalised in international migration studies. This article arises from a broader investigation into the role of such organisations in the peopling of Australia and Canada from the 1890s to 1939: their visions, relationships with governments, significance and legacies. The aim is to bring a new perspective to comparative migration and population research and to assess how far such organisations paralleled, or stepped outside of, the racialised, gendered and class structures of ofŽficial immigration policies and  practices of the time. Here the focus is particularly on the place of women and girls in the migration schemes of some of the organisations operating in both Australia and Canada. The use of case studies such as the British Women’s Emigration Association, the Salvation Army and Dr Barnardo’s Homes provides an opportunity to examine the sexual distinctions implicit in these schemes and the direction of both women and men into what were seen at the time as gender-appropriate societal roles and occupations.

Cancer risk among people with type 1 and type 2 diabetes: disentangling true associations, detection bias, and reverse causation

 OBJECTIVE: Evidence indicates an increased risk of certain cancers among people with type 2 diabetes. Evidence for rarer cancers and for type 1 diabetes is limited. We explored the excess risk of site-specific cancer incidence and mortality among people with type 1 and type 2 diabetes, compared with the general Australian population. RESEARCH DESIGN AND METHODS: Registrants of a national diabetes registry (953,382) between 1997 and 2008 were linked to national death and cancer registries. Standardized incidence and mortality ratios (SIRs/SMRs) are reported. RESULTS: For type 1 diabetes, significant elevated SIRs were observed for pancreas, liver, esophagus, colon and rectum (females only [F]), stomach (F), thyroid (F), brain (F), lung (F), endometrium, and ovary, and decreased SIRs were observed for prostate in males. Significantly increased SMRs were observed for pancreas, liver, and kidney (males only), non-Hodgkin's lymphoma, brain (F), and endometrium. For type 2 diabetes, significant SIRs were observed for almost all site-specific cancers, with highest SIRs observed for liver and pancreas, and decreased risks for prostate and melanoma. Significant SMRs were observed for liver, pancreas, kidney, Hodgkin's lymphoma, gallbladder (F), stomach (F), and non-Hodgkin's lymphoma (F). Cancer risk was significantly elevated throughout follow-up time but was higher in the first 3 months postregistration, suggesting the presence of detection bias and/or reverse causation. CONCLUSIONS: Type 1 and type 2 diabetes are associated with an excess risk of incidence and mortality for overall and a number of site-specific cancers, and this is only partially explained by bias. We suggest that screening for cancers in diabetic patients is important.

The limitations of using statutory child protection data for research into child maltreatment

Child protection legislation has undergone a number of changes since its inception, changes that have redefined the population of children in need of protection. However, child protection data on notifications and substantiations remain the most common source of data for statistics on the rate of maltreatment and the breakdown of specific maltreatment types. In the present study, three factors are identified that have compromised the accuracy of child protection data reporting the incidence of child abuse and neglect: (i) the legislative changes that mandate child protection services to protect children from harm rather than from identifiable adult actions; (ii) the shift from the Harm Standard to the Endangerment Standard; and (iii) the assignment of responsibility solely to parents.

Population health and wellbeing: identifying priority areas for Victorian children

Background
Population health information, collected using soundly-designed methodologies, is essential to inform policy, research, and intervention programs. This study aimed to derive policy-oriented recommendations for the content of a health and wellbeing population survey of children 0–12 years living in Victoria, Australia.

Results
Qualitative interviews were conducted with 54 academic and policy stakeholders, selected to encompass a wide breadth of expertise in areas of public health and inter-sectoral organisations relevant to child health outcomes, including universities, government and non-government agencies across Victoria. These stakeholders were asked to provide advice on strategic priorities for child health information (data) using a structured interview technique. Their comments were summarised and the major themes were extracted. The priority areas of health and wellbeing recommended for regular collection include obesity and its determinants, pregnancy and breastfeeding, oral health, injury, social and emotional health and wellbeing, family environment, community, health service utilisation, illness, and socioeconomic position. Population policy questions for each area were identified.

Conclusion
In contrast to previous population survey programs nationally and internationally, this study sought to extract contemporary policy-oriented domains for inclusion in a strategic program of child health data collection, using a stakeholder consultation process to identify key domains and policy information needs. The outcomes are a rich and relevant set of recommendations which will now be taken forward into a regular statewide child health survey program.

Complaint behaviour: a study of the differences between complainants about advertising in Australia and the population at large

Advertising expenditure has risen globally and in Australia there has been a 2.7-fold increase in the last ten years. It is suggested that some advertisements may be “unacceptable”, that is, unfair, misleading, deceptive, offensive, false or socially irresponsible. This research is concerned with consumer behaviour and consumer complaint behaviour specifically in the area of advertising in Australia. The findings indicate that complainants are significantly different from the population at large. This research will afford the regulatory bodies a better understanding of the complaining public as well as educating marketing communications strategists in effectively reaching their target markets.

The health and well-being of adolescents: a school-based population study of the self-report child health questionnaire

Purpose: To evaluate a new generic measure of adolescent health status, the self-report version of the Child Health Questionnaire (CHQ), and provide population-based data. Furthermore, we aimed to examine the impact of common adolescent illness and health concerns on their health and well-being.

Methods: A stratified, two-stage, random cluster sampling design was used to obtain a cross-sectional sample of subjects through schools. A written questionnaire included the 80-item 12-scale self-report CHQ and items measuring health concerns, illnesses/health conditions, and sociodemographics.

Results: A total of 2361 adolescents participated (response rate of 70%). Reliability was high: Tests of internal consistency and discriminant validity reported 90% of item-scale correlations >.4; all scales had Cronbach alpha coefficients >.7. Adolescents with illnesses/conditions or health concerns reported lower scores and larger differences for content-related scales, supporting content and construct validity. Statistically significant age and gender trends were observed for Mental Health, Self-Esteem, General Health, and Family Cohesion scales. Health status worsened as health concerns increased (X2 linear trend, p = .00) with deterioration in health of 5–20% on all scales for emotional health concerns (40% of sample).

Conclusions: The self-report CHQ is a reliable and seemingly valid measure of health and well-being for adolescent health research, although additional measures may be required where scales have high ceiling values. The significantly lower scores reported by adolescents with illness and/or health concerns lend support to the use of standardized health measures and longitudinal research to further examine the impact of adolescent comorbidities and their causal determinants.

Working with local government to research strategic development within regional Victoria

Changes in population size and composition, forecasted for regional Victorian cities, have the potential to significantly impact upon their urban environments. The Built Environment Research Group (BERG) at Deakin
University, in collaboration with The Centre for Sustainable Regional Communities at La Trobe University, is currently working with the City of Greater Bendigo and the City of Warrnambool to research this situation. The following paper introduces the work being undertaken to develop strategies for promoting an integrated approach to regional development, and  addresses the administrative context supporting current decision-making processes within local government.

Marketing of place to attract and retain population in regional Australia

In Australia, as in many other developed countries, regional and rural areas are suffering from an overall decline in population with a specific loss of young adults (16-30 year olds). A decline in population, linked with the Australia-wide problems of ageing populations and diminishing birth rates, is leading to a social and economic decline in many regional cities and towns that threatens their long-term sustainability due to the lack of skilled workers and professionals. Although the loss of population from regional and rural areas has the potential to affect the national economy, it has mainly fallen to local government to combat the problem. Local government is beginning to use place marketing to attract and retain residents in addition to its traditional use of place marketing to attract industry and investment.

This exploratory paper examines regional decline in Australia and the concept of "place" marketing as means of arresting or reversing the decline, A conceptual model of place marketing by local government in Australia has been developed and a number of hypothesis are proposed for testing in future research.

Video games research: gender inequities

In this paper we explore current research on violence in video games, with a focus on gender inequalities and imbalance, and introduce a project being undertaken as part of an honours programme in Information Technology. The research focuses on the portrayal of violence in games as perceived by future game developers and the parallel issue of lack of female participation as players and developers. Although the project is in its infancy it has already highlighted a major shortcoming in video games research which will have a major impact on the results. Lack of gender representation in the population being surveyed limits the generality of any results obtained, which has a domino effect on the ability of the games industry to address gender issues.

What have sampling and data collection got to do with good qualitative research?

Objective: To highlight the importance of sampling and data collection  processes in qualitative interview studies, and to discuss the contribution of  these processes to determining the strength of the evidence generated and  thereby to decisions for public health practice and policy.

Approach: This discussion is informed by a hierarchy-of-evidence-for-practice  model. The paper provides succinct guidelines for key sampling and data  collection considerations in qualitative research involving interview studies. The  importance of allowing time for immersion in a given community to become  familiar with the context and population is discussed, as well as the practical  constraints that sometimes operate against this stage. The role of theory in  guiding sample selection is discussed both in terms of identifying likely sources  of rich data and in understanding the issues emerging from the data. It is noted  that sampling further assists in confirming the developing evidence and also  illuminates data that does not seem to fit. The importance of reporting sampling  and data collection processes is highlighted clearly to enable others to assess  both the strength of the evidence and the broader applications of the findings.

Conclusion: Sampling and data collection processes are critical to determining  the quality of a study and the generalisability of the findings. We argue that  these processes should operate within the parameters of the research goal, be  guided by emerging theoretical considerations, cover a range of relevant   participant perspectives, and be clearly outlined in research reports with an  explanation of any research limitations.

High childhood obesity in an Australian population

Objective: The objective was to determine the prevalences of overweight and obesity in regional Australian children and to examine the association between BMI and indicators of socioeconomic status (SES).

Research Methods and Procedures: Regionally representative cross-sectional survey of 2184 children, 4 to 12 years of age, was conducted, and the socio-demographic characteristics of their parents from regional Victoria, Australia, 2003 to 2004, were obtained.

Results: The prevalences of overweight and obesity were 19.3 plusminus 0.8% (proportion plusminus standard error) and 7.6 plusminus 0.6% , respectively, using international criteria, and the proportion of overweight/obese girls was significantly higher than that of boys (29.6 plusminus 1.4% vs. 23.9 plusminus 1.3% , chi2 = 9.01, p = 0.003). Children from households of lower SES had higher odds of being overweight/obese; lower SES was defined by lower paternal education (adjusted odds ratio, 1.18; 95% confidence interval, 1.08 to 1.30) and lower area-level SES (adjusted odds ratio, 1.13; 95% confidence interval, 1.02 to 1.25), adjusted for age, gender, height, and clustering by school.

Discussion: The prevalences of overweight and obesity are increasing in Australian children by about one percentage point per year. This equates to approx40,000 more overweight children each year, placing Australian children among those at highest risk around the world. In addition, girls are more likely to be overweight, and there is a general trend for children of lower SES to be at even greater risk of overweight and obesity.

A new broad composite model of regional economic development as a framework for research

The mechanism of regional economic development has been studied extensively by economists, geographers, town planners and other academics. The existing wide varieties of theories into regional economic development are insufficient on their own in explaining how a region can develop and prosper. Each theory has evaluated a few facets of regional economic development. Research from these different perspectives is narrow and prevents any cross-fertilization of research from all these diverse
theories.

Recognition of multiple factors affecting the development process has led the author to create a new broad composite model of regional economic development. The paper first sets out to describe and explain this broad composite model. Each of the components of this new model draws heavily upon seminal work in the field. This model proposes three rings. Each ring is at a different level of abstraction. The determinants of development described in each ring can influence each and every other determinant of development shown in the three ring structure. This model recognises that development in any centre, regional or urban, nascent or established is a composite end result of the complex interplay of all the determinants of development.

The paper then goes on to show how this model can provide a broad holistic approach to regional economic development that can assist researchers in their attempts to understand and link the various theories of regional economic development.
