Outcomes of population based language promotion for slow to talk toddlers at ages 2 and 3 years: let’s learn language cluster randomised controlled trial

Objective To determine the benefits of a low intensity parent-toddler language promotion programme delivered to toddlers identified as slow to talk on screening in universal services.
Design Cluster randomised trial nested in a population based survey.
Setting Three local government areas in Melbourne, Australia.
Participants Parents attending 12 month well child checks over a six month period completed a baseline questionnaire. At 18 months, children at or below the 20th centile on an expressive vocabulary checklist entered the trial.
Intervention Maternal and child health centres (clusters) were randomly allocated to intervention (modified “You Make the Difference” programme over six weekly sessions) or control (“usual care”) arms.
Main outcome measures The primary outcome was expressive language (Preschool Language Scale-4) at 2 and 3 years; secondary outcomes were receptive language at 2 and 3 years, vocabulary checklist raw score at 2 and 3 years, Expressive Vocabulary Test at 3 years, and Child Behavior Checklist/1.5-5 raw score at 2 and 3 years.
Results 1217 parents completed the baseline survey; 1138 (93.5%) completed the 18 month checklist, when 301 (26.4%) children had vocabulary scores at or below the 20th centile and were randomised (158 intervention, 143 control). 115 (73%) intervention parents attended at least one session (mean 4.5 sessions), and most reported high satisfaction with the programme. Interim outcomes at age 2 years were similar in the two groups. Similarly, at age 3 years, adjusted mean differences (intervention−control) were −2.4 (95% confidence interval −6.2 to 1.4; P=0.21) for expressive language; −0.3 (−4.2 to 3.7; P=0.90) for receptive language; 4.1 (−2.3 to 10.6; P=0.21) for vocabulary checklist; −0.5 (−4.4 to 3.4; P=0.80) for Expressive Vocabulary Test; −0.1 (−1.6 to 1.4; P=0.86) for externalising behaviour problems; and −0.1 (−1.3 to 1.2; P=0. 92) for internalising behaviour problems.
Conclusion This community based programme targeting slow to talk toddlers was feasible and acceptable, but little evidence was found that it improved language or behaviour either immediately or at age 3 years.

The role of play in teaching English as foreign language in early childhood settings in Indonesia.

This research highlights a teacher’s transformative thinking which has profound implications on how teachers conceptualise child play and learning, thus leads to a way of thinking about English as a foreign language (EFL) could better be supported through the use of play-based pedagogies, especially dramatic play in Indonesian context.

The infant feeding activity and nutrition trial (INFANT) an early intervention to prevent childhood obesity : cluster-randomised controlled trial

Background : Multiple factors combine to support a compelling case for interventions that target the development of obesity-promoting behaviours (poor diet, low physical activity and high sedentary behaviour) from their inception. These factors include the rapidly increasing prevalence of fatness throughout childhood, the instigation of obesity-promoting behaviours in infancy, and the tracking of these behaviours from childhood through to adolescence and adulthood. The Infant Feeding Activity and Nutrition Trial (INFANT) aims to determine the effectiveness of an early childhood obesity prevention intervention delivered to first-time parents. The intervention, conducted with parents over the infant's first 18 months of life, will use existing social networks (first-time parent's groups) and an anticipatory guidance framework focusing on parenting skills which support the development of positive diet and physical activity behaviours, and reduced sedentary behaviours in infancy.

Methods/Design : This cluster-randomised controlled trial, with first-time parent groups as the unit of randomisation, will be conducted with a sample of 600 first-time parents and their newborn children who attend the first-time parents' group at Maternal and Child Health Centres. Using a two-stage sampling process, local government areas in Victoria, Australia will be randomly selected at the first stage. At the second stage, a proportional sample of first-time parent groups within selected local government areas will be randomly selected and invited to participate. Informed consent will be obtained and groups will then be randomly allocated to the intervention or control group.

Discussion : The early years hold promise as a time in which obesity prevention may be most effective. To our knowledge this will be the first randomised trial internationally to demonstrate whether an early health promotion program delivered to first-time parents in their existing social groups promotes healthy eating, physical activity and reduced sedentary behaviours. If proven to be effective, INFANT may protect children from the development of obesity and its associated social and economic costs.

Verbal declarative memory impairments in specific language impairment are related to working memory deficits

This study examined verbal declarative memory functioning in SLI and its relationship to working memory. Encoding, recall, and recognition of verbal information was examined in children with SLI who had below average working memory (SLILow WM), children with SLI who had average working memory (SLIAvg. WM) and, a group of non-language impaired children with average working memory (TDAvg. WM). The SLILow WM group was significantly worse than both the SLIAvg. WM and TDAvg. WM groups at encoding verbal information and at retrieving verbal information following a delay. In contrast, the SLIAvg. WM group showed no verbal declarative memory deficits. The study demonstrates that verbal declarative memory deficits in SLI only occur when verbal working memory is impaired. Thus SLI declarative memory is largely intact and deficits are likely to be related to working memory impairments.

Symptoms of depression and difficulty initiating sleep from early adolescence to early adulthood: a longitudinal study

STUDY OBJECTIVES: To assess the direction of the relationship and degree of shared associations between symptoms of depression and difficulty initiating sleep (DIS) from early adolescence to early adulthood. DESIGN: Cross-sectional and longitudinal assessment of the symptoms of depression-DIS association from early adolescence (age 13 y) to early adulthood (age 23 y). SETTING: Hordaland, Norway. PARTICIPANTS: There were 1,105 individuals (55% male) who took part in the Norwegian Longitudinal Health Behaviour Study (NLHB) and participated at least once across seven data collection waves during the years 1990-2000. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Characteristic data were obtained during the first assessment. Symptoms of depression and instances of DIS were assessed during each data collection wave. Symptoms of depression and DIS were associated in all data waves, and one-step cross-lagged bivariate correlations were significant and comparatively high for both factors. Structural equation modelling indicated that DIS and symptoms of depression at wave 1 remain relatively stable across waves (all P < 0.001), and a significant and consistent unidirectional cross-lagged effect was noted running from symptoms of depression to DIS from early adolescence to early adulthood. DIS is only marginally and inconsistently associated with the lagged symptoms of depression score across waves. CONCLUSIONS: These results suggest that symptoms of depression established in early adolescence are a moderate predictor of difficulty initiating sleep (DIS) in early adulthood, whereas the reverse association of DIS predicting depression was not convincingly supported. These findings are in contrast to previous findings that suggest sleep problems as a risk factor for the later development of depression.

The extended Infant Feeding, Activity and Nutrition Trial (InFANT Extend) Program : a cluster-randomized controlled trial of an early intervention to prevent childhood obesity

BACKGROUND: Understanding how we can prevent childhood obesity in scalable and sustainable ways is imperative. Early RCT interventions focused on the first two years of life have shown promise however, differences in Body Mass Index between intervention and control groups diminish once the interventions cease. Innovative and cost-effective strategies seeking to continue to support parents to engender appropriate energy balance behaviours in young children need to be explored. METHODS/DESIGN: The Infant Feeding Activity and Nutrition Trial (InFANT) Extend Program builds on the early outcomes of the Melbourne InFANT Program. This cluster randomized controlled trial will test the efficacy of an extended (33 versus 15 month) and enhanced (use of web-based materials, and Facebook® engagement), version of the original Melbourne InFANT Program intervention in a new cohort. Outcomes at 36 months of age will be compared against the control group. DISCUSSION: This trial will provide important information regarding capacity and opportunities to maximize early childhood intervention effectiveness over the first three years of life. This study continues to build the evidence base regarding the design of cost-effective, scalable interventions to promote protective energy balance behaviors in early childhood, and in turn, promote improved child weight and health across the life course.

Cross-fostering reduces obesity induced by early exposure to monosodium glutamate in male rats

Maternal obesity programmes a range of metabolic disturbances for the offspring later in life. Moreover, environmental changes during the suckling period can influence offspring development. Because both periods significantly affect long-term metabolism, we aimed to study whether cross-fostering during the lactation period was sufficient to rescue a programmed obese phenotype in offspring induced by maternal obesity following monosodium L-glutamate (MSG) treatment. Obesity was induced in female Wistar rats by administering subcutaneous MSG (4 mg/g body weight) for the first 5 days of postnatal life. Control and obese female rats were mated in adulthood. The resultant pups were divided into control second generation (F2) (CTLF2), MSG-treated second generation (F2) (MSGF2), which suckled from their CTL and MSG biological dams, respectively, or CTLF2-CR, control offspring suckled by MSG dams and MSGF2-CR, MSG offspring suckled by CTL dams. At 120 days of age, fat tissue accumulation, lipid profile, hypothalamic leptin signalling, glucose tolerance, glucose-induced, and adrenergic inhibition of insulin secretion in isolated pancreatic islets were analysed. Maternal MSG-induced obesity led to an obese phenotype in male offspring, characterized by hyperinsulinaemia, hyperglycaemia, hyperleptinaemia, dyslipidaemia, and impaired leptin signalling, suggesting central leptin resistance, glucose intolerance, impaired glucose-stimulated, and adrenergic inhibition of insulin secretion. Cross-fostering normalized body weight, food intake, leptin signalling, lipid profiles, and insulinaemia, but not glucose homeostasis or insulin secretion from isolated pancreatic islets. Our findings suggest that alterations during the lactation period can mitigate the development of obesity and prevent the programming of adult diseases.

Location, perception and dissolution of form 1991-1993

The thesis covers a series of two and three-dimensional installations created in the investigation of both metaphorical and literal perceptions of form. The journey leads from the idea of painted-related dissolution of form in the early works, to the translation from three-dimensional to two-dimensional installations, and lastly, to experimentation with sound works where non-physical form is explored.

Using language and culture to construct group work in higher education

Second language students’ experiences of group work is not often transparent in evaluation studies although the multicultural nature of the student population in Australasia would suggest that culture and language should be on the research agenda. Culture and language is used in the higher education literature to mark out the Asian learner as different and problematic although such cultural models and stereotypes have been the subject of some criticism in recent years. Through semi-structured qualitative interviewing in focus group interviews with 19 South East Asian students I explore the ways language and culture intervene to structure these students’ experiences.

Heteroglossia : a space for developing critical language awareness?

This paper reports on research into the challenges of implementing a critical writing pedagogy within a teacher education program in Australia. Participants in this study are student teachers enrolled in a compulsory subject, “Language and Literacy in Secondary School”, a subject requiring them to develop a knowledge of the role of language and literacy across the secondary school curriculum and to show personal proficiency in literacy as part of graduate outcomes for teacher education dictated by the State Government of Victoria. To develop an understanding of the way that language has shaped their lives, students write a narrative about their early literacy experiences – a task which they all find very challenging, especially in comparison with the formal writing of other university subjects. Rather than simply reminiscing about their early childhood, they are encouraged to juxtapose voices from the past and the present, and to combine a range of texts within their writing. Later in the semester they revisit these accounts of their early literacy experiences and, in a separate piece of writing, endeavour to place these accounts within the contexts of theories and debates they have encountered in the course of completing this unit. The students’ writing provides a small window on how they are experiencing their tertiary education and their preparation as teachers, including the managerial controls that are currently shaping university curriculum and pedagogy. We argue that such heteroglossic texts (Bakhtin, 1981) prompt students to stretch their repertoires as language-users, enabling them to develop a socially critical awareness of language and literacy, including the literacy practices in which they engage as university students.

A middle approach to literacy in a minority Indigenous Australian language context.

Kunib-dji live in Maningrida, a remote community in the Northern Territory and speak Ndj-bbana as their preferred language of communication. Kunib-dji are one of many groups of Indigenous Australian languages who speak a minority language. Very little has been documented about the social practices of literacy with speakers of such languages, particularly with the texts that mediate these languages. Knowing about the beliefs and attitudes towards enacted by these speakers towards these texts is useful for understanding the process of learning of minority and majority languages. This paper presents a middle approach to literacy as distinct form top-down and bottom-up approaches, that has emerged from the minority Indigenous Australian language context in Maningrida. The proposed middle approach to literacy incorporates non-indigenous intervention in Indigenous social practices and technological transform of Indigenous texts. The methodological aspects of such intervention and transformation together with the implications of a middle approach to literacy are presented in this paper. Throughout the paper references are made to Kunib-dji children's access to digital Ndj-bbana texts and their engagement with these texts in a home environment.

The role of effective partnerships in an Australian place-based intervention to reduce race-based discrimination

Localities Embracing and Accepting Diversity (LEAD) is an ongoing place-based pilot program aimed at improving health outcomes among Aboriginal and migrant communities through increased social and economic participation. Specifically, LEAD works with mainstream organizations to prevent race-based discrimination from occurring. The partnership model of LEAD was designed to create a community intervention that was evidence-based, effective, and flexible enough to respond to local contexts and needs. LEAD's complex organizational and partnership model, in combination with an innovative approach to reducing race-based discrimination, has necessitated the use of new language and communication strategies to build genuinely collaborative partnerships. Allocating sufficient time to develop strategies aligned with this new way of doing business has been critical. However, preliminary data indicate that a varied set of partners has been integral to supporting the widespread influence of the emerging LEAD findings across partner networks in a number of different sectors.
