The inverse relationship between number of steps per day and obesity in a population-based sample - the AusDiab study

Background:
Physical activity (PA) is inversely associated with obesity but the effect has been difficult to quantify using questionnaires. In particular, the shape of the association has not yet been well described. Pedometers provide an opportunity to better characterize the association.

Methods:
Residents of households over the age of 25 years in randomly selected census districts in Tasmania were eligible to participate in the AusDiab cross-sectional survey conducted in 1999–2000. 1848 completed the AusDiab survey and 1126 of these (609 women and 517 men) wore a pedometer for 2-weekdays. Questionnaire data on recent PA, TV time and other factors were obtained. The outcomes were waist circumference (in cm) and body mass index (BMI) (kg/m2).

Results:
Increasing daily steps were associated with a decline in the obesity measures. The logarithmic nature of the associations was indicated by a sharper decline for those with lower daily steps. For example, an additional 2000 steps for those taking only 2000 steps per day was associated with a reduction of 2.8 (95% confidence interval (CI): 2.1,4.4) cm in waist circumference among men (for women; 2.2 (95% CI: 0.6, 3.9 cm)) with a baseline of only 2000, steps compared to a 0.7 (95% CI 0.3, 1.1) cm reduction (for women; 0.6 (95% CI: 0.2, 1.0)) for those already walking 10 000 steps daily. In the multivariable analysis, clearer associations were detected for PA and these obesity measures using daily step number rather than PA time by questionnaire.

Interpretation:
Pedometer measures of activity indicate that the inverse association between recent PA and obesity is logarithmic in form with the greatest impact for a given arithmetic step number increase seen at lower levels of baseline activity. The findings from this study need to be examined in prospective settings.

Refugee : a recipe in six steps (2004)- Documenting the hidden

The research involved the production of a documentary and exegesis, arguing that to emphasise the importance of the indexical image in documentary is to overlook the active involvement of viewers, who don't need to see reality in order to infer that a given film is making arguments about reality.

Two steps forward, one step back : Indonesia’s arduous path to reform

Australians have long worried about whether Indonesia is ‘special’ or ‘normal’. Instead, we need to deal with Indonesia as it really is—a country experiencing simultaneously the challenges of political reform, economic development and a shifting regional security environment. The country’s political future is less certain than we would hope: after SBY’s term of government ends, the choice of a successor will be critical in determining the future of reform. We can’t rule out that Indonesia might slide back to old ways of doing business—democratisation is a fraught process.
As the Indonesian economy grows, so too do the prospects for Indonesia to establish its natural position as the leader of Southeast Asia. As the world is re-examining Indonesia, so too Indonesia is looking afresh at the world—more interested in external issues than it was a decade ago. The Southeast Asian subregion increasingly finds itself at the centre of a more strongly interconnected Indo-Pacific region—so Indonesia’s strategic importance is going up.
It’s important for Australia to build a better strategic relationship with Indonesia. The two are complementary partners. Australia should be proactive in exploring new opportunities for cooperation with a reform minded Indonesia—it’s in our interests to draw Indonesia into a more important strategic role in regional security.

Steps in the design, development and formative evaluation of obesity prevention-related behavior change trials

Obesity prevention interventions through dietary and physical activity change have generally not been effective. Limitations on possible program effectiveness are herein identified at every step in the mediating variable model, a generic conceptual framework for understanding how interventions may promote behavior change. To minimize these problems, and thereby enhance likely intervention effectiveness, four sequential types of formative studies are proposed: targeted behavior validation, targeted mediator validation, intervention procedure validation, and pilot feasibility intervention. Implementing these studies would establish the relationships at each step in the mediating variable model, thereby maximizing the likelihood that an intervention would work and its effects would be detected. Building consensus among researchers, funding agencies, and journal editors on distinct intervention development studies should avoid identified limitations and move the field forward.

Science teacher educator partnerships with schools (STEPS): developing an interpretive framework for primary science teacher education

The STEPS Project responds to international concern about primary teachers’ lack of science knowledge and confidence to teach science, and recent questioning of the effectiveness of traditional approaches to teacher education. The project reviews and builds on established, innovative and successful practices at five universities, to develop and promote a framework supporting school‐based approaches to pre‐service teacher education. This paper will outline the processes involved in developing an Interpretive Framework, which will be a key outcome of the project. The Interpretive Framework identifies key elements to assist teacher educators in planning, implementing and sustaining school-based approaches to teacher education.

Data Integration Protocol In Ten-steps (DIPIT) : a new standard for medical researchers

The exponential increase in data, computing power and the availability of readily accessible analytical software has allowed organisations around the world to leverage the benefits of integrating multiple heterogeneous data files for enterprise-level planning and decision making. Benefits from effective data integration to the health and medical research community include more trustworthy research, higher service quality, improved personnel efficiency, reduction of redundant tasks, facilitation of auditing and more timely, relevant and specific information. The costs of poor quality processes elevate the risk of erroneous outcomes, an erosion of confidence in the data and the organisations using these data. To date there are no documented set of standards for best practice integration of heterogeneous data files for research purposes. Therefore, the aim of this paper is to describe a set of clear protocol for data file integration (Data Integration Protocol In Ten-steps; DIPIT) translational to any field of research.

Science teacher education partnerships with schools (STEPS): partnerships in science teacher education

This paper reports on the STEPS project which addressed international concerns about primary teachers' lack of confidence to teach science, and on-going questions about the effectiveness of teacher education. The five universities involved had each independently established a science education program incorporating school-based partnerships between the university and local schools to enable primary pre-service teachers (PSTs) to teach science. The diversity of the programs enabled an examination of the relevant literature underpinning the approaches and comparison of data from participants to identify key features and success factors for establishing and maintaining working relationships with schools. This preliminary analysis of learning from STEPS uses case studies and feedback from PSTs who participated. These findings indicate that authentic teaching experiences build the confidence of PSTs to teach science. Ultimately, the project will develop an Interpretive Framework which will articulate the characteristics of partnerships to be validated through feedback from other science educators from Australia and overseas.
