Reducing electronic media use in 2-3 year-old children: feasibility and efficacy of the Family@play pilot randomised controlled trial

BACKGROUND: Participation in electronic media use among 2-3 year olds is high and associated with adverse health and developmental outcomes. This study sought to test the feasibility and potential efficacy of a family-based program to decrease electronic media (EM) use in 2-3-year-old children. METHODS: Family@play was a six-session pilot randomised controlled trial delivered to parents of 2-3 year-old children from August to September 2012 in a community environment in the Illawarra region of New South Wales, Australia. Development of program content was guided by Social Cognitive and Family Systems Theories. The primary outcome was children's electronic media use. Secondary outcomes included children's time in sitting, standing and stepping. Data collectors were blinded to group allocation. Parents completed comprehensive process evaluation measures and participated in focus group discussions following completion of the program. Regression analyses were undertaken and effect sizes calculated using principles of intention to treat. RESULTS: Twenty-two participants (n = 12 intervention; n = 10 control) provided complete baseline data; complete data from 16 participants (n = 6 intervention; n = 10 control) were available post-intervention. Process evaluation results were high, showing the acceptability of the program. Compared with children in the control group, there were greater decreases in total EM use among children in the intervention group (adjusted difference [95 % CI] = -31.2 mins/day [-71.0-8.6] Cohen's d = 0.70). Differences for other outcomes were in the hypothesised direction and ranged from small for postural (sitting, standing, stepping) outcomes to moderate to large for individual electronic media (e.g. TV viewing, DVD/video viewing). CONCLUSIONS: This is the first family-based study to engage families of 2-3 year old children outside the United States and target multiple EM behaviours. Family@play was shown to be a feasible and acceptable intervention to deliver to families of 2-3 year old children. Potential efficacy is evident from moderate to large effect sizes. A larger trial is warranted to test the efficacy of the program. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry ( ACTRN12612000470897 ).

East and West, past and present: rekindle old principles for new management practices

This paper explores the sayings and stories of the ancient Chinese philosophers Guanzi, Hanfeizi, Xunzi and Yanzi. Their way of ruling the state and managing the people are analysed and discussed in line with thoughts from the mainstream and modern Western management gurus, such as Warren Bennis, Peter Drucker, Mary Parker Follett, Douglas McGregor, Rosabeth Moss Kanter, Elton Mayo, and Jeffrey Pfeffer. Striking similarities call for addressing key issues in human resource management. East and west thinkers across 3000 years are identified. The principles-based ruling and management were found difficult to be taken seriously in ancient times as it is today. However, these principles must be rekindled to protect organisations and the world from mischievous behaviour that has caused much human suffering.

Australia’s Colombo plans, old and new: international students as foreign relations

This article draws on recent research and policy developments to make a case for considering international students as an important component of Australian foreign relations. It links historical and contemporary Australian experiences of international students, especially in the Colombo Plan and New Colombo Plan, to the field of public diplomacy, and sets an agenda for further research in this direction. It highlights the need to recover student voices and to be sensitive to the emergence of everyday or ‘vernacular’ internationalism, as a phenomenon of international students visiting, traveling and otherwise encountering different groups of Australians. It suggests a need to take up anew this form of inquiry for both earlier postwar student experiences and the post-1980s period, in which international students’ voices are frequently silenced by debates over commodification, funding needs, and neo-liberal economics.

Uteroplacental insufficiency leads to hypertension, but not glucose intolerance or impaired skeletal muscle mitochondrial biogenesis, in 12-month-old rats

Growth restriction impacts on offspring development and increases their risk of disease in adulthood which is exacerbated with "second hits." The aim of this study was to investigate if blood pressure, glucose tolerance, and skeletal muscle mitochondrial biogenesis were altered in 12-month-old male and female offspring with prenatal or postnatal growth restriction. Bilateral uterine vessel ligation induced uteroplacental insufficiency and growth restriction in offspring (Restricted). A sham surgery was also performed during pregnancy (Control) and some litters from sham mothers had their litter size reduced (Reduced litter), which restricted postnatal growth. Growth-restricted females only developed hypertension at 12 months, which was not observed in males. In Restricted females only homeostasis model assessment for insulin resistance was decreased, indicating enhanced hepatic insulin sensitivity, which was not observed in males. Plasma leptin was increased only in the Reduced males at 12 months compared to Control and Restricted males, which was not observed in females. Compared to Controls, leptin, ghrelin, and adiponectin were unaltered in the Restricted males and females, suggesting that at 12 months of age the reduction in body weight in the Restricted offspring is not a consequence of circulating adipokines. Skeletal muscle PGC-1α levels were unaltered in 12-month-old male and female rats, which indicate improvements in lean muscle mass by 12 months of age. In summary, sex strongly impacts the cardiometabolic effects of growth restriction in 12-month-old rats and it is females who are at particular risk of developing long-term hypertension following growth restriction.

Evidential in Persian editorials

Based on the analysis of 267 tokens derived from editorial columns primarily drawn from two Persian newspapers, following on earlier studies by Chafe, Jahani, Lazard, Dahl, Adel, and Dafouze, and inspired by a series of Hyland’s studies on metadiscourse signals, this study has aimed at investigating evidential markers in these columns. In order to come to grips with the types of evidentials, first, we classify them into two major types – inferential and reportative; the reportative evidentials are further classified into four types. The reportative classification is based, in the first place, on whether the source of information comes from an individual or from a government body, hence institutional. The further classifications are based on their identifiability/specificity. Results show that inferential evidentials comprise about 15% of all the tokens. Among the four reportative types, those whose source is individual and identified/specified and those that are institutional and unidentified/unspecified, coded as TYPE 1 and TYPE 4, respectively, have the highest frequency. The results overall show that Persian editorials in these two papers feature a high frequency of attribution of information to identified sources when the source is individual (TYPE 1), but to unidentified sources when the source is institutional (TYPE 4). The results also support other authors (e.g. Lazard) who claim that the imperfective (progressive) aspect marker mi-, which is frequent in Persian, is a marker worthy of consideration in evidentiality.

The 45 year old health check - feasibility and impact on practices and patient behaviour

Background: The 45 year old health check (MBS item 717) for patients aged 45-49 years was introduced in 2006. This study evaluated its impact on preventive care and patient reported risk factors. Methods: A quantitative and qualitative study was conducted in eight general practices in Sydney, New South Wales. It involved follow up surveys of 118 patients taken both before the check and 3 months after. Practice staff were trained and supported to conduct the health checks and appropriate interventions. Results: There was ambivalence among some of the general practitioners toward the health check, but most found it feasible. The reported frequency of GP advice relating to each of the SNAP (smoking, nutrition, alcohol, and physical activity) risk factors increased; patient referrals, however, were infrequent. Patients' readiness to change their diet and exercise habits improved as a result of the check, with respondents showing an increase in both the consumption of vegetables and the frequency of physical activity. There was no change in body mass index, smoking or alcohol consumption. Discussion: The health check was associated with a short term improvement in diet and physical activity behaviours. Mechanisms to enhance referral need to be developed.
