Exploring physical activities in an employer-sponsored health program

This work brings a perspective from an employer-sponsored health and wellness program called Global Corporate Challenge (GCC) to the 'quantified self' research. We present preliminary findings from a study with 17 university employees who participated in the GCC. We aimed to explore how participants derived meaningfulness from their self-tracking experiences. Our findings echo the growing body of work that advocates for conceptualizing activity tracking beyond the rationalistic, data-oriented perspectives and supporting more social and lived experiences.

Exploring motivations of young adults to participate in physical activities

This paper investigates the motivations of young adults aged 18 to 24 years to participate in physical activities and how technology might best support this motivation. Motivational factors were studied through contextual interviews, an adapted cultural probe activity and a survey with a group of young adults currently active in sports. From our preliminary findings we determine that staying healthy, achieving specific goals and socialising represent key motivational factors for young adults to be active in sports, but also, that exercise is not considered a high priority in their daily lives. A link between the motivation of achieving specific goals and a technology to measure and track activities was established. The study concludes with three implications for the design of technology to motivate young adults to participate in sports.

Fixing the alignment: An exploration of budgeting practices in the home

Budgeting is an important means of controlling ones finances and reducing debt. This paper outlines our work towards designing more user centred technology for individual and household budgeting. Based on an ethnographically informed study with 15 participants, we highlight a misalignment between people's actual budgeting practices and those supported by off-the-shelf budgeting aids. In addressing this misalignment we outline three tenets that may be incorporated into future work in this area. These include (1) catering for the different phases of engagement with technology; (2) catering for the practices of hiding and limiting access to money, and; (3) integrating materiality into technical solutions.

The messaging kettle: Prototyping connection over a distance between adult children and older parents

A prototype "messaging kettle" is described. The connected kettle aims to foster communication and engagement with an older friend or relative who lives remotely, during the routine of boiling the kettle. We describe preliminary encounters and findings from demonstrating a working prototype in morning tea gatherings of people in their 50s-late 70s and from introducing it into the homes of two people in their 80s who live on another continent. Key findings are that: The concept of keeping in touch around a "habituated object" such as a kettle was well received; Simple and varied interaction modalities that allow asymmetric forms of communication are needed; Designing for use across different time zones requires attention; And, that even when augmenting a habituated object, the process of introduction, appropriation and habituation still needs significant attention and investigation.

Bringing the farmer perspective to agricultural robots

The research reported in this paper explores autonomous technologies for agricultural farming application and is focused on the development of multiple-cooperative agricultural robots (AgBots). These are highly autonomous, small, lightweight, and unmanned machines that operate cooperatively (as opposed to a traditional single heavy machine) and are suited to work on broadacre land (large-scale crop operations on land parcels greater than 4,000m2). Since this is a new, and potentially disruptive technology, little is yet known about farmer attitudes towards robots, how robots might be incorporated into current farming practice, and how best to marry the capability of the robot with the work of the farmer. This paper reports preliminary insights (with a focus on farmer-robot control) gathered from field visits and contextual interviews with farmers, and contributes knowledge that will enable further work toward the design and application of agricultural robotics.

A tsunami of unmet needs: Pancreatic and ampullary cancer patients’ supportive care needs and use of community and allied health services

Objective People diagnosed with pancreatic cancer have the worst survival prognosis of any cancer. No previous research has documented the supportive care needs of this population. Our objective was to describe people’s needs and use of support services and to examine whether these differed according to whether or not patients had undergone surgical resection. Methods Queensland pancreatic or ampullary cancer patients (n=136, 54% of those eligible) completed a survey which assessed 34 needs across 5 domains (SCNS-SF34) and use of health services. Differences by resection were compared with Chi-squared tests. Results Overall, 96% of participants reported having some needs. More than half reported moderate-to-high unmet physical (54%) or psychological (52%) needs whereas, health system/information (32%), patient care (21%) and sexuality needs (16%) were described less frequently. The three most frequently reported moderate-to-high needs included ‘not being able to do things they used to do’ (41%), ‘concerns about the worries of those close’ (37%), and ‘uncertainty about the future’ (30%). Patients with non-resectable disease reported greater individual information needs but their needs were otherwise similar to patients with resectable disease. Self-reported use of support was low; only 35% accessed information, 28%, 18% and 15% consulted a dietician, complementary medicine practitioner or mental health practitioner, respectively. Palliative care access was greater (59% vs 27%) among those with non-resectable disease. Conclusion Very high levels of needs were reported by people with pancreatic or ampullary cancer. Future work needs to elucidate why uptake of appropriate supportive care is low and which services are required.

Choosing appropriate contract methods for design-build projects

For design-build (DB) projects, owners normally use lump sum and Guaranteed Maximum Price (GMP) as the major contract payment provisions. However, there was a lack of empirical studies to compare the project performance within different contract types and investigate how different project characteristics affect the owners’ selection of contract arrangement. Project information from Design-build Institute of America (DBIA) database was collected to reveal the statistical relationship between different project characteristics and contract types and to compare project performance between lump sum and GMP contract. The results show that lump sum is still the most frequently used contract method for DB projects, especially in the public sector. However, projects using GMP contract are more likely to have less schedule delay and cost overrun as compared to those with lump sum contract. The chi-square tests of cross tabulations reveal that project type, owner type, and procurement method affect the selection of contract types significantly. Civil infrastructure rather than industrial engineering project tends to use lump sum more frequently; and qualification-oriented contractor selection process resorts to GMP more often compared with cost-oriented process. The findings of this research contribute to the current body of knowledge concerning the effect of associated project characteristics on contract type selection. Overall, the results of this study provide empirical evidence from real DB projects that can be used by owners to select appropriate contract types and eventually improve future project performance.

Gearing up academics for collaborative Building Information Modelling (BIM) education

Building information modelling (BIM) radically changes the practices in architecture, engineering and construction (AEC) and creates new job opportunities. Many governments, such as the United Kingdom, have made BIM a mandatory requirement. This substantially drives the demand for a BIM-literate workforce. Universities are facing the challenge to incorporate BIM into their curricula and produce “BIM ready” graduates to meet the needs of the industry. Like other universities, Queensland University of Technology (QUT) is at the heart of this change and aspires to develop collaborative BIM education across AEC. Previous BIM education studies identify that inadequate BIM awareness of AEC academics is one of the challenges for developing a BIM curriculum and there is a dearth in the learning and teaching support for academics on BIM education. Equipping the AEC academics for a more BIM focused curriculum is all the while more important. This paper aims to leverage knowledge drawn from a Learning & Teaching project currently undertaken at QUT. Its specific objectives are to: 1) review the existing learning and teaching initiatives on BIM education; and 2) briefly describe the learning and teaching activities on collaborative BIM education at QUT. Significance of the paper lies on revealing the importance of building up the capacity of AEC academics for collaborative BIM education. The paper contributes to sparking the interests in better equipping AEC academics to understand what curriculum changes would assist in BIM uptake within the relevant courses to provide context for changes in units; and how the use of BIM can improve the understanding by students of the large amounts of professional knowledge they need to function effectively as graduates.

Weight-related risk perception among healthy and overweight pregnant women: A cross-sectional study

Objective The objective of this study was to evaluate weight-related risk perception in early pregnancy and to compare this perception between women commencing pregnancy healthy weight and overweight. Study design Pregnant women (n=664) aged 29±5 (mean±s.d.) years were recruited from a metropolitan teaching hospital in Australia. A self-administered questionnaire was completed at around 16 weeks of gestation. Height measured at baseline and self-reported pre-pregnancy weight were used to calculate body mass index. Cross-sectional analysis was conducted. Differences between groups were assessed using chi-squared tests for categorical variables and t-tests or Mann–Whitney U tests for continuous variables depending on distribution. Result Excess gestational weight gain (GWG) during pregnancy was more important in leading to health problems for women or their child compared with pre-pregnancy weight. Personal risk perception for complications was low for all women, although overweight women had slightly higher scores than healthy-weight women (2.4±1.0 vs 2.9±1.0; P<0.001). All women perceived their risk for complications to be below that of an average pregnant woman. Conclusion Women should be informed of the risk associated with their pre-pregnancy weight (in the case of maternal overweight) and excess GWG. If efforts to raise risk awareness are to result in preventative action, this information needs to be accompanied by advice and appropriate support on how to reduce risk.

Hosting asylum seekers and attitudes toward cultural diversity in Australia

In 2012, the Australian government in office introduced a novel scheme of housing asylum seekers as guests of Australians in the community. A number of Australians participated in the scheme and volunteered as hosts. This study compared those who volunteered to assist asylum seekers with general members of the community to explore the impact attitudes towards cultural diversity and demographic factors had upon willingness to support asylum seekers. Further, the two groups were combined to examine the factors that can contribute to positive attitudes to diversity in society in general. Participants (N = 142; aged from 24-79 years) completed online questionnaires assessing demographic variables, attitudes towards cultural diversity and acculturation. Various analysis of variance procedures, Chi-squared tests and correlations were conducted. Group comparisons indicated that volunteers’ attitudes did not impact on willingness to support asylum seekers. However, some demographic differences between groups emerged. Volunteers were more likely to be professionals with stable jobs, ethnically diverse and well-travelled individuals. Analyses on the combined groups indicated age, education and not having a strong religious affiliation enhanced Australians’ positive attitudes to cultural diversity. The findings have implications for promoting positive attitudes to diversity in individuals, organisations and communities. Potential opportunities for professionals and policy-makers to promote support for cultural diversity in the community are discussed.

Nonlinear analysis for the pre- and post-yield behaviour of a hybrid structure by a higher-order element with the refined plastic hinge approach

Efficient and accurate geometric and material nonlinear analysis of the structures under ultimate loads is a backbone to the success of integrated analysis and design, performance-based design approach and progressive collapse analysis. This paper presents the advanced computational technique of a higher-order element formulation with the refined plastic hinge approach which can evaluate the concrete and steel-concrete structure prone to the nonlinear material effects (i.e. gradual yielding, full plasticity, strain-hardening effect when subjected to the interaction between axial and bending actions, and load redistribution) as well as the nonlinear geometric effects (i.e. second-order P-d effect and P-D effect, its associate strength and stiffness degradation). Further, this paper also presents the cross-section analysis useful to formulate the refined plastic hinge approach.

The 'gender gap' in authorship in nursing literature

OBJECTIVES: Gender bias has been found in medical literature, with more men than women as first or senior authors of papers, despite about half of doctors being women. Nursing is about 90% female, so we aimed to determine if similar biases exist in nursing literature. DESIGN: Taking the eight non-specialist nursing journals with the highest impact factors for that profession, we counted the numbers of men and women first authors over 30 years. SETTING: We used nursing journals from around the world which attract the highest impact factors for nursing publication. PARTICIPANTS: Eight journals qualified for entry, three from the United Kingdom, four from the United States of America, and one from Australia. MAIN OUTCOME MEASURES Using Chi-square and Fisher exact tests, we determined differences between the numbers of men and women across all the journals, between countries (USA, UK and Australia), changes over the 30 years, and changes within journals over time. RESULTS Despite the small proportion of men in the nursing workforce, up to 30% of first authors were men. UK journals were more likely to have male authors than USA journals, and this increased over time. USA journals had proportions of male first authors consistent with the male proportion of its nursing workforce. CONCLUSIONS In the UK (though not in the USA) gender bias in nursing publishing exists, even though the nursing workforce is strongly feminized. This warrants further research, but is likely to be due to the same reasons for the gender gap in medical publishing; that is, female nurses take time out to have families, and social and family responsibilities prevent them taking opportunities for career progression, whereas men's careers often are not affected in such ways.

Yellow Peril

This catalogue essay was written to accompany Eugenia Lim's 2015 exhibition at Metro Arts, Brisbane, 'Yellow Peril'. It discusses Lim's exploration of her identity as a Chinese-Australian, providing contextual information of Chinese immigration during Australia's gold rush years and the work of Hong Kong born American artist, Tseng Kwong Chi. It presents Yellow Peril as an exhibition that speaks critically about art and our cultural history amidst a fine layering of imagery, object and context, with a vitality that is derived from its rich and compelling base in real life moments and connections.

Case-control study of ADARB1 and ADARB2 gene variants in migraine

Background: Migraine causes crippling attacks of severe head pain along with associated nausea, vomiting, photophobia and/or phonophobia. The aim of this study was to investigate single nucleotide polymorphisms (SNPs) in the adenosine deaminase, RNA-specific, B1 (ADARB1)and adenosine deaminase, RNA specific, B2 (ADARB2) genes in an Australian case-control Caucasian population for association with migraine. Both candidate genes are highly expressed in the central nervous system (CNS) and fit criteria for migraine neuropathology. SNPs in the ADARB2 gene were previously found to be positively associated with migraine in a pedigree-based GWAS using the genetic isolate of Norfolk Island, Australia. The ADARB1 gene was also chosen for investigation due to its important function in editing neurotransmitter receptor transcripts. Methods: Four SNPs in ADARB1 and nine in ADARB2 were selected by inspecting blocks of LD in Haploview for genotyping using either TaqMan or Sequenom assays. These SNPs were genotyped in two-hundred and ninety one patients who satisfied the International Classification of Headache Disorders, ICHD-II 2004 diagnostic criteria for migraine and three-hundred and fourteen controls and PLINK was used for association testing. Results: Chi-square (χ2) analysis found no significant association between any of the SNPs tested in the ADARB1 and ADARB2 genes in this study and the occurrence of migraine. Conclusions: In contrast to findings that SNPs in the ADARB2 gene were positively associated with migraine in the Norfolk Island population, we find no evidence to support the involvement of RNA editing genes in migraine susceptibility in an Australian Caucasian population.
