Profiles of language development in pre-school children : a longitudinal latent class analysis of data from the early language in Victoria study

<b>Background</b> Pre-school language impairment is common and greatly reduces educational performance. Population attempts to identify children who would benefit from appropriately timed intervention might be improved by greater knowledge about the typical profiles of language development. Specifically, this could be used to help with the early identification of children who will be impaired on school entry.<br /><br /><b>Methods</b> This study applied longitudinal latent class analysis to assessments at 8, 12, 24, 36 and 48 months on 1113 children from a population-based study, in order to identify classes exhibiting distinct communicative developmental profiles.<br /><br /><b>Results</b> Five substantive classes were identified: Typical, i.e. development in the typical range at each age; Precocious (late), i.e. typical development in infancy followed by high probabilities of precocity from 24 months onwards; Impaired (early), i.e. high probabilities of impairment up to 12 months followed by typical language development thereafter; Impaired (late), i.e. typical development in infancy but impairment from 24 months onwards; Precocious (early), i.e. high probabilities of precocity in early life followed by typical language by 48 months. The entropy statistic (0.84) suggested classes were fairly well defined, although there was a non-trivial degree of uncertainty in classification of children. That half of the Impaired (late) class was expected to have typical language at 4 years and 6% of the numerically large Typical class was expected to be impaired at 4 years illustrates this. Characteristics indicative of social advantage were more commonly found in the classes with improving profiles.<br /><br /><b>Conclusions</b> Developmental profiles show that some pre-schoolers' language is characterized by periods of accelerated development, slow development and catch-up growth. Given the uncertainty in classifying children into these profiles, use of this knowledge for identifying children who will be impaired on school entry is not straightforward. The findings do, however, indicate greater need for language enrichment programmes among disadvantaged children.<br />

Talking books for children's home use in a minority Indigenous Australian language context

Members of the Kunibidji community are the traditional owners of the lands and seas around Maningrida, a remote community in Northern Australia. Most of the 200 members of the Kunibidji Community speak Ndjebbana as their first language. This study reports on the complexities of transforming technology to provide Kunib&iacute;dji children with access to digital texts at home. The printed Ndjebbana texts that were kept at school were transformed to Ndjebbana talking books displayed on touch screen computers in the children's homes. Some results of the children's interaction around these touch screens are presented as well as some quantitative results of the computer viewing in the homes. The processes of rejecting technological determinism, upholding linguistic human rights of speakers of minority languages and viewing technology as practice rather than a set of artefacts are discussed in this paper. The results of this study highlight the need for speakers of minority Indigenous Australian languages to have access to texts in their threatened languages on technologies at home.

Oral language competence, young speakers and the Law

<b>Purpose</b>: This paper highlights the forensic implications of language impairment in 2 key (and overlapping) groups of young people: identified victims of maltreatment (abuse and/or neglect) and young offenders.<br /><br /><b>Method</b>: Two lines of research pertaining to oral language competence and young people's interface with the law are considered: 1 regarding investigative interviewing with children as victims or witnesses in the context of serious allegations of sexual abuse, and the other pertaining to adolescent offenders as suspects, witnesses, or victims. The linguistic demands that forensic interviewing places on these young people are also considered. Literature concerning the impact of early maltreatment on early language acquisition is briefly reviewed, as is the role of theory of mind in relation to the requirements of investigative interviewing of children and adolescents.<br /><br /><b>Implications</b>: High-risk young people (i.e., those who are subject to child protection orders because of suspected or confirmed maltreatment, and those who are engaged with the youth justice system) face an elevated risk for suboptimal language development but may need to draw on their language skills in high-stakes forensic interviews. Implications for early intervention policy and practice are identified, and the need for greater speech-language pathology advocacy and engagement in forensic interviewing research is emphasized.<br />

Randomized trial of a population-based, home-delivered intervention for preschool language delay

<b>OBJECTIVE</b>:&nbsp;<div>Population approaches to lessen the adverse impacts of preschool language delay remain elusive. We aimed to determine whether systematic ascertainment of language delay at age 4 years, followed by a 10-month, 1-on-1 intervention, improves language and related outcomes at age 5 years.<br /><br /><b>METHODS</b>: <br />A randomized trial nested within a cross-sectional ascertainment of language delay. Children with expressive and/or receptive language scores more than 1.25 SD below the mean at age 4 years entered the trial. Children randomly allocated to the intervention received 18 1-hour home-based therapy sessions. The primary outcomes were receptive and expressive language (Clinical Evaluation of Language Fundamentals &ndash; Preschool, 2nd Edition) and secondary outcomes were child phonological skills, letter awareness, pragmatic skills, behavior, and quality of life.<br /><br /><b>RESULTS</b>: <br />A total of 1464 children were assessed for language delay at age 4 years. Of 266 eligible children, 200 (13.6%) entered the trial, with 91 intervention (92% of 99) and 88 control (87% of 101) children retained at age 5 years. At age 5 years, there was weak evidence of benefit to expressive (adjusted mean difference, intervention &minus; control, 2.0; 95% confidence interval [CI] &minus;0.5 to 4.4; P = .12) but not receptive (0.6; 95% CI &minus;2.5 to 3.8; P = .69) language. The intervention improved phonological awareness skills (5.0; 95% CI 2.2 to 7.8; P &lt; .001) and letter knowledge (2.4; 95% CI 0.3 to 4.5; P = .03), but not other secondary outcomes.<br /><br /><b>CONCLUSIONS</b>: <br />A standardized yet flexible 18-session language intervention was successfully delivered by non-specialist staff, found to be acceptable and feasible, and has the potential to improve long-term consequences of early language delay within a public health framework.</div>

Generating domain-specific visual language tools from abstract visual specifications

Domain-specific visual languages support high-level modeling for a wide range of application domains. However, building tools to support such languages is very challenging. We describe a set of key conceptual requirements for such tools and our approach to addressing these requirements, a set of visual language-based metatools. These support definition of metamodels, visual notations, views, modeling behaviors, design critics, and model transformations and provide a platform to realize target visual modeling tools. Extensions support collaborative work, human-centric tool interaction, and multiplatform deployment. We illustrate application of the metatoolset on tools developed with our approach. We describe tool developer and cognitive evaluations of our platform and our exemplar tools, and summarize key future research directions.<br />

The early language in Victoria study: predicting vocabulary at age one and two years from gesture and object use

The Macarthur-Bates Communicative Development Inventories (CDI) have been used widely to document early communicative development. The paper reports on a large community sample of 1,447 children recruited from low, middle and high socioeconomic (SES) areas across metropolitan Melbourne, Australia. Regression analyses were conducted to determine the extent to which communicative behaviours reported at 0 ; 8 and 1 ; 0 predicted vocabulary development at 1 ; 0 and 2 ; 0. In support of previous findings with smaller, often less representative samples, gesture and object use at 1 ; 0 were better predictors of 2 ; 0 vocabulary than were gesture and object use at 0 ; 8. At 1 ; 0, children from the lower SES groups were reported to understand more words than children from the higher SES groups, but there were no SES differences for words produced at 1 ; 0 or 2 ; 0. The findings add to our understanding of the variability in the development of early communicative behaviours.

Language functioning, mental health and alexithymia in incarcerated young offenders

Purpose: Previous studies describe high rates of language impairment in young offenders; however, important correlates such as mental health status and alexithymia have received little attention.<br />Method: This study describes a cross-sectional study of the language, emotion recognition and mental health of 100 young people completing custodial sentences in New South Wales (Australia). The sample comprised 70 young people from nonindigenous<br />backgrounds (n&frac14;60 male) and 30 from indigenous backgrounds (n&frac14;25 male). The mean age of the sample was 17.1 years. It was hypothesized that, in addition to elevated rates of language impairment, alexithymia would be overrepresented in this group. It was further predicted that impoverished language skills would contribute to alexithymia scores.<br />Result: Only a quarter of the sample overall achieved Clinical Evaluation of Language Fundamentals (CELF-4) Core Language Scores in the expected range; rates of language impairment were higher in indigenous males than in nonindigenous males and in the females. Alexithymia was present in 59% of the sample, but appeared to be associated with poor mental health, rather than with language impairment.<br />Conclusion: Interventions for young offenders (e.g. psychological counselling, restorative justice conferencing) should be framed around these difficulties. Validated language measures for use with young indigenous offenders are needed.

Actors and agency in academic language policy and planning

Nearly two decades have passed since Kaplan and Baldauf [1997. Language planning from practice to theory. Clevedon: Multilingual Matters] drew attention to the dearth of language policy and planning (LPP) in higher education. Despite the continuing inflow of English as an additional language students into Anglophone universities, and a boom in English-medium instruction policies in non-Anglophone tertiary institutions [Dearden, J. (2014). English as a medium of instruction: A growing global phenomenon. British Council], LPP research remains relatively underdeveloped in higher education. We suggest that current understandings of academic language policy and planning in higher education would benefit from contextualised analyses of actors and agency [Chua, C. S. K., &amp; Baldauf, R. B. (2011). Micro language planning. In E. Hinkel (Ed.), Handbook of research in second language teaching and learning (pp. 936&ndash;951). New York, NY: Routledge; Zhao, S. H., 2011. Actors in language planning. In E. Hinkel (Ed.), Handbook of research in second language teaching and learning (Vol. II, pp. 905&ndash;923). New York, NY: Routledge; Zhao, S. H., &amp; Baldauf, R. B. (2012). Individual agency in language planning: Chinese script reform as a case study. Language Problems &amp; Language Planning, 36(1), 1&ndash;24]. In order to address this gap, we conducted semi-structured interviews with 10 academic language program planners at different universities across Australia. We examined how the micro-level processes of program development and implementation were both constrained and enabled by the participation of different actor groups, operating at different levels (micro, meso, macro) and each with their own capacity to influence change. We conclude by arguing that coherent university-wide language policies, formulated by decision-making bodies representative of a variety of stakeholder groups and sensitive to program implementation needs at the micro level, represent a step towards improving the current situation.

"It's got to be more than that". Parents and speech-language pathologists discuss training content for families with a new speech generating device.

PURPOSE: Although parent-implemented interventions for children with a speech-generating device (SGD) have been well researched, little is known about parents' or speech-language pathologists' (SLPs) views around parent training content. In this project, we aimed to identify areas that parents and SLPs consider should be included in training for families with a new SGD. <br /><br />METHODS: Seven parents of children with an SGD and three SLPs who were new to the SGD field, participated in individual semi-structured interviews. Ten SLPs experienced in SGD practice took part in two focus groups. Data were analysed using grounded theory methods. <br /><br />RESULTS: Participants identified the following areas suitable for inclusion in a family SGD training package: (a) content aimed at improving acceptance and uptake of the SGD, including technical guidance, customisation and reassurance around SGD misconceptions; (b) content around aided language development and (c) home practice strategies, including responsivity, aided language stimulation and managing children's motivation. <br /><br />CONCLUSIONS: Participants identified diverse training targets, many of which are unexplored in parent-training research to date. Their recounted experiences illustrate the diversity of family capacity, knowledge and training priorities, and highlight the need for collaborative planning between families and SLPs at all stages of SGD training. Implications for Rehabilitation Training needs for families with a new speech generating device (SGD) are diverse, ranging from technology-specific competencies to broader areas, such as advocacy, teamwork and goal-setting skills. Each family with a new SGD will have a unique profile of training needs, determined by individual learning capacity, priorities, prior knowledge and experience, as well as their child's current communication skills and future support needs. Parents and speech-language pathologists (SLPs) may hold different priorities concerning family SGD training, necessitating ongoing team discussion.

Two-year outcomes of a population-based intervention for preschool language delay : an RCT

OBJECTIVE: We have previously shown short-term benefits to phonology, letter knowledge, and possibly expressive language from systematically ascertaining language delay at age 4 years followed by the Language for Learning intervention. Here, we report the trial's definitive 6-year outcomes. METHODS: Randomized trial nested in a population-based ascertainment. Children with language scores &gt;1.25 SD below the mean at age 4 were randomized, with intervention children receiving 18 1-hour home-based therapy sessions. Primary outcome was receptive/expressive language. Secondary outcomes were phonological, receptive vocabulary, literacy, and narrative skills; parent-reported pragmatic language, behavior, and health-related quality of life; costs of intervention; and health service use. For intention-to-treat analyses, trial arms were compared using linear regression models. RESULTS: Of 1464 children assessed at age 4, 266 were eligible and 200 randomized; 90% and 82% of intervention and control children were retained respectively. By age 6, mean language scores had normalized, but there was little evidence of a treatment effect for receptive (adjusted mean difference 2.3; 95% confidence interval [CI] -1.2 to 5.7; P = .20) or expressive (0.8; 95% CI -1.6 to 3.2; P = .49) language. Of the secondary outcomes, only phonological awareness skills (effect size 0.36; 95% CI 0.08-0.65; P = .01) showed benefit. Costs were higher for intervention families (mean difference AU$4276; 95% CI: $3424 to $5128). CONCLUSIONS: Population-based intervention targeting 4-year-old language delay was feasible but did not have lasting impacts on language, possibly reflecting resolution in both groups. Long-term literacy benefits remain possible but must be weighed against its cost.

Teacher stories of collusion and transformation: a feminist pedagogical framework and meta-language for cultural gender justice

This article examines data from two different studies concerning issues of social justice, gender and schooling and specifically the practices of secondary teachers, &lsquo;Mr B&rsquo;, a teacher from a school in Tasmania, Australia, and &lsquo;Mr C&rsquo;, a teacher from a school in Bedfordshire in the United Kingdom. Both teachers&rsquo; practices and relationships with students are analysed within a feminist interpretation of the Productive Pedagogies model of quality teaching and learning. The two different stories are presented as juxtapositions that serve to illuminate the capacities of pedagogy to, on the one hand, work in ways likely to re-inscribe the discourses of entitlement and privilege that perpetuate cultural gender injustice, and on the other, transform these discourses towards more equitable and just networks of multiple and intersecting differences.

������Glossary Islands��� as sites of the ���Abroad��� in post-colonial literature: towards a new methodology for language and knowledge relations in Keri Hulme���s The Bone People and Melissa Lucashenko���s Mullumbimby.���

The publication of Melissa Lucashenko&rsquo;s Mullumbimby in 2013 drew attention once more to the issue of how post-colonial scholars might best engage with English-language literary texts also containing a glossary of Indigenous words. This issue emerged first with the publication of Keri Hulme&rsquo;s The Bone People in 1984. This article argues that, to date, scholars like Simon During and Eve Vincent have perpetuated a binary either/or approach to the interpretation of these glossaries. The result of this approach has been that either the pre-colonial Indigenous language or the colonial/post-colonizing English language has been privileged as the locus of linguistic power in the text. One problem with this approach is that it does not adequately represent the complex historical, cultural and political circumstances of post-colonial and multi-cultural nations like Australia (setting of Mullumbimby) and New Zealand (setting of The Bone People) as these link to matters of language. Another problem is that this binary approach restrains a close reading of the differences between different types of such glossaries, and of the nuanced relationship of a glossary to the text it accompanies. In place of this approach, this article proposes a new methodology that works with Elizabeth M. DeLoughrey&rsquo;s notion of &ldquo;tidalectics&rdquo; as a way of reading island literatures. The neologism &ldquo;glossary islands&rdquo; allows another way into considering the function of glossaries in islandic literary texts like Lucashenko&rsquo;s and Hulme&rsquo;s. The post-colonial connection between islands and glossaries lies in the fact that they are each an intensified site of knowledge.
