Steps and sitting in a working population

This study aimed to assess sitting time and number of steps taken each day, and the relationships between these variables, in a sample of working Australian adults. Workers (N = 185), wore a pedometer for 7 days and recorded the number of steps taken and time spent sitting each day. Average time spent sitting on weekdays was 9.4 (SD = 2.40) hr with about half spent sitting at work. Despite this, the average steps taken each day (M = 8,873, SD = 2,757) was higher on weekdays than on weekend days. There was a clear inverse relationship between sitting time at work and number of steps taken on weekdays, r = -.34, p < .001); those in the highest tertile for sitting time reported about 3,000 fewer daily steps. Workers in managerial and professional occupations reported more time sitting at work (M = 6.2 hr per day) and lower weekday step counts (M = 7,883, N = 43) than technical (M = 3.3 hr sitting at work and 10,731 weekday steps, N = 33) and blue collar workers (M = 1.6 hours sitting and 11,784 steps N = 11). The findings suggest those whose daily work involves long hours of sitting should be the focus of efforts to promote physical activity both within and outside the workplace.

Living on the ground research: Steps towards white women researching in collaboration with indigenous people

De Ishtar discusses ways in which Whites could develop research epistemologies and methodologies which responded to and reflected those being developed by Indigenous researchers across Australia and around the world. She details her own explorations in developing a methodology which enabled her to work in collaboration with a group of Indigenous women elders from Western Australia's Great Sandy Desert. She stresses that if collaborative research with Indigenous women is to be possible, White feminists must learn how to do research which is culturally unobtrusive, and that means taking responsibility for their own cultural practices, attitudes and values.

Steps in theory-of-mind development for children with deafness or autism

Prior research demonstrates that understanding theory of mind (ToM) is seriously and similarly delayed in late-signing deaf children and children with autism. Are these children simply delayed in timing relative to typical children, or do they demonstrate different patterns of development? The current research addressed this question by testing 145 children (ranging from 3 to 13 years) with deafness, autism, or typical development using a ToM scale. Results indicate that all groups followed the same sequence of steps, up to a point, but that children with autism showed an importantly different sequence of understandings (in the later steps of the progression) relative to all other groups.

Dissemination of a community-based physical activity project: The case of 10,000 steps

This paper describes the use of a web-site for the dissemination of the community-based '10,000 steps' program which was originally developed and evaluated in Rockhampton, Queensland in 2001-2003. The website provides information and interactive activities for individuals, and promotes resources and programs for health promotion professionals. The dissemination activity was assessed in terms of program adoption and implementation. In a 2-year period (May 2004-March 2006) more than 18,000 people registered as users of the web-site (togging more than 8.5 billion steps) and almost 100 workplaces and 13 communities implemented aspects of the 10,000 steps program. These data support the use of the internet as an effective means of disseminating ideas and resources beyond the geographical borders of the original project. Following this preliminary dissemination, there remains a need for the systematic study of different dissemination strategies, so that evidence-based physical activity programs can be translated into more widespread public health practice.

Cinderella no longer: alpha-catenin steps out of cadherin's shadow

To date, alpha-catenin has been best understood as an important cytoplasmic component of the classical cadherin complex responsible for cell-cell adhesion. By virtue of its capacity to bind F-actin, alpha-catenin was commonly envisaged to support cadherin function by coupling the adhesion receptor to the actin cytoskeleton. But is alpha-catenin solely the cadherin's handmaiden? A range of recent developments suggest, instead, that its biological activity is much more complex than previously appreciated. Evidence from cellular systems and model organisms demonstrates a clear, often dramatic, role for alpha-catenin in tissue organization and morphogenesis. The morphogenetic impact of alpha-catenin reflects its capacity to mediate functional cooperation between cadherins and the actin cytoskeleton, but is not confined to this. alpha-Catenin has a role in regulating cell proliferation and cadherin-independent pools of alpha-catenin may contribute to its functional impact.

Paediatric research in emergency departments international collaborative (PREDICT): First steps towards the development of an Australian and New Zealand research network

Paediatric emergency research is hampered by a number of barriers that can be overcome by a multicentre approach. In 2004, an Australia and New Zealand-based paediatric emergency research network was formed, the Paediatric Research in Emergency Departments International Collaborative (PREDICT). The founding sites include all major tertiary children’s hospital EDs in Australia and New Zealand and a major mixed ED in Australia. PREDICT aims to provide leadership and infrastructure for multicentre research at the highest standard, facilitate collaboration between institutions, health-care providers and researchers and ultimately improve patient outcome. Initial network-wide projects have been determined. The present article describes the development of the network, its structure and future goals.
