Recent research suggests the disorder is not restricted to the language domain and against this background, the challenge for the practitioner is to provide accurate assessment and effective therapy. The language practitioner aims to support the child and their carers to achieve the best outcomes. However, little is known about the experiences of the language practitioner in the assessment process, in contrast to other childhood disorders, yet their expertise is central in the assessment and diagnosis of children with language disorder. Aims: This study aimed to provide a detailed qualitative description of the experiences of speech and language therapists involved in the assessment and diagnosis of children with Developmental Language Disorder. Methods & Procedures: The qualitative study included three focus groups to provide a credible and rich description of the experiences of speech and language therapists involved in the assessment of Developmental Language Disorder. The speech and language therapists who participated in the study were recruited from three NHS Trusts across the UK and all were directly involved in the assessment and diagnosis procedures. The lengths of practitioner experience ranged from 2 years to 38 years. The data was analysed using a thematic analysis in accordance with the principles set out by Braun & Clarke (2006). Outcomes & Results: The data showed a number of key themes concerning the experiences of speech and language therapists in assessing children with Developmental Language Disorder (DLD). These themes ranged from the participantsâ experiences of the barriers to early referral, challenges for assessment and the concerns over continued future support. Conclusions & Implications: This study provides first-hand evidence from speech and language therapists in the assessment of children with Developmental Language Disorder, drawing together experiences from language practitioners from different regions. The findings provide insight to the barriers to referral, the potential variations in the assessment process, the role of practitioner expertise and the challenges faced them. The importance of early intervention, useful assessment tools and future support were expressed. Taken together, the results relate to some issues to be addressed on a practical level and a continuing need for initiatives to raise awareness of DLD in the public domain.Peer reviewe

The hybrid identity of micro enterprises: Contrasting the perspectives of community pharmaciesâ owners-managers and employees
Purpose: The purpose of this paper is to examine the effect of ownership of community pharmacies on the perception of organizational identity and its relationships with organizational performance.
Design/methodology/approach: A survey was carried out on a sample of pharmacists working in community pharmacies in Portugal. The sample comprised 1,369 pharmacists, of whom 51 percent were owner-managers. Measures of pharmaciesâ normative (community health oriented) and utilitarian (business oriented) identities, identity strength (clear and unifying), substantive (stockholder focused) and symbolic (society focused) performance were included.
Findings: Both owners and employed pharmacists rated the normative identity of pharmacies higher than the utilitarian identity. Compared with employed pharmacists, owners perceive a lower level of utilitarian identity, the same level of normative identity, and higher levels of identity strength. Normative identity and identity strength predicted symbolic performance. Normative and utilitarian identities and identity strength predicted substantive performance. The relationship between utilitarian identity and substantive performance was significant among owner pharmacists but not among employed pharmacists.
Research limitations/implications: The limitations include the use of perceptive measures and the focus on the individual level of analysis.
Practical implications: In order to improve pharmaciesâ performance, pharmacists who manage community pharmacies are challenged to reconcile tensions arising from the co-existence of business and community health identities and from their own agency (self-serving) and stewardship (altruistic) motives.
Originality/value: This study draws on institutional, identity and stewardship theories to understand how pharmacists, owners and employees, view the identity of community pharmacies and how identity relates to organizational performance
Genome-wide association study of receptive language ability of 12 year olds
Purpose: We have previously shown that individual differences in measures of receptive language ability at age 12 are highly heritable. The current study attempted to identify some of the genes responsible for the heritability of receptive language ability using a genome-wide association (GWA) approach.
Method: We administered four internet-based measures of receptive language (vocabulary, semantics, syntax, and pragmatics) to a sample of 2329 12-year-olds for whom DNA and genome-wide genotyping were available. Nearly 700,000 single-nucleotide polymorphisms (SNPs) and one million imputed SNPs were included in a GWA analysis of receptive language composite scores.
Results: No SNP associations met the demanding criterion of genome-wide significance that corrects for multiple testing across the genome (p < 5 Ă10-8). The strongest SNP association did not replicate in an additional sample of 2639 12-year-olds.
Conclusion: These results indicate that individual differences in receptive language ability in the general population do not reflect common genetic variants that account for >3% of the phenotypic variance. The search for genetic variants associated with language skill will require larger samples and additional methods to identify and functionally characterize the full spectrum of risk variants
Improving storytelling and vocabulary in secondary school students with language disorder: a randomized controlled trial
Background: Although language and communication difficulties are common in secondary school students, there has been limited research into the efficacy of interventions for adolescents with language and communication difficulties. Aims: To investigate the efficacy of teaching assistant (TA)-delivered narrative and vocabulary interventions to mainstream secondary school-aged students with language disorder. Methods & Procedures: A randomized controlled trial (RCT) of a language and communication intervention was used to evaluate the efficacy of vocabulary and narrative interventions to improve the vocabulary and narrative performance of adolescents (mean age = 12.8 years) with language disorder. The language and communication programmes (narrative, vocabulary and combined narrative and vocabulary) were delivered by TAs in the classroom, three times per week, for 45â60 min each, over 6 weeks, totalling 18 sessions. Standardized and intervention-specific measures were used as outcomes. Outcomes & Results: Twenty-one schools with 358 eligible participants were recruited. The three intervention groups showed significant improvements (d =.296) on a narrative latent variable defined by a standardized narrative assessment (the Expression, Reception and Recall of Narrative InstrumentâERRNI), but there were no significant improvements on an overall vocabulary latent variable compared with the waiting control group. Differential effects were found on some non-standardized intervention-specific measures with the narrative group making significantly more progress on narrative tasks compared with the waiting control group, the vocabulary group showing the same pattern on specific vocabulary tasks, and the combined narrative and vocabulary group making significantly more progress on some of the intervention-specific narrative, and all the intervention-specific vocabulary outcomes compared with the waiting control group. Conclusions & Implications: It is possible to improve narrative but not vocabulary skills, as assessed by standardized measures, in secondary school students with a relatively brief group TA-delivered intervention. There were differential effects for both narrative and vocabulary with intervention-specific measures. Future work is required to explore whether more intensive and longer lasting interventions would be more effective and to identify which students in this age group are most likely to benefit from such interventions
How set switching affects the use of context-appropriate language by autistic and neuro-typical children
Autistic children have difficulties in adapting their language for particular listeners and contexts. We asked whether these difficulties are more prominent when children are required to be cognitively flexible, when changing how they have previously referred to a particular object. We compared autistic (N = 30) with neuro-typical five- to seven-year-olds. Each child participated in two conditions. In the Switch condition the same animal had to be re-described across trials to be appropriately informative (e.g. a participant could appropriately describe a picture as âdogâ on one trial but later the participant needed to re-describe the same picture as âspotty dogâ to differentiate it from a co-present black dog). In the No-Switch condition no picture needed to be re-described. Nonetheless, the conditions were matched regarding the requirement to use both complex (e.g. spotty cat) versus simple expressions (e.g. horse). Autistic children were more over-informative than peers even prior to the requirement to re-describe an animal. Overall, we found a main effect of the Switch Condition and no interaction with Group. Switching a description hinders the ability of children to be appropriately informative. As autistic children are generally less appropriately informative, the requirement to switch leads to particularly poor performance in autism. Lay abstract The way autistic individuals use language often gives the impression that they are not considering how much information listeners need in a given context. The same child can give too much information in one context (e.g. saying âthe big cupâ with only one cup present) and too little information in another context (e.g. entering a room and announcing âthe red oneâ when the listener has no prior knowledge regarding what this refers to). We asked whether many autistic children particularly struggle to tailor their language appropriately in situations where this means changing how they have previously described something. That is, if a speaker has recently described an object as âthe cupâ, the need to switch to describing it as âthe big cupâ could hinder the speakerâs ability to use language in a context-appropriate way.We found that switching descriptions indeed makes it more difficult for children to use language in a context-appropriate way, but that this effect did not play out differently for autistic versus neuro-typical children. Autistic children were, however, less likely to provide a context-appropriate amount of information overall than were neuro-typical peers. The combination of these effects meant that when object re-description was required, autistic children only produced an appropriate description half the time. In contrast, without a requirement to redescribe, autistic children could indeed take listener informational needs into account. Applied professionals should consider whether a requirement to change the way the child has previously said something may hinder a childâs ability to communicate effectively
Making sense of social pretense: The effect of the dyad, sex and language ability in a large observational study of childrenâs behaviors in a social pretend play context
Pretend play with peers is purportedly an important driver of social development in the preschool period, however, fundamental questions regarding the features of childrenâs pretend play with a peer, and the effect of the dyad for pretend play, have been overlooked. The current study undertook detailed behavioral coding of social pretend play in 134 pairs of 5-year-old children (54% boys) in order to address three main aims: (i) describe the duration and proportion of children engaging in key social pretend play behaviors, namely, calls for attention, negotiation (comprising role assignment and joint proposals) and enactment of pretend play, (ii) examine the effect of the dyad in influencing the occurrence of different social pretend play behaviors, and (iii) assess the independent and combined effect of individual child characteristics (i.e., language ability and sex) that may influence social pretend play behaviors beyond the influence of the dyad. Results demonstrated the overwhelming effect of the dyad in shaping childrenâs social pretend play behaviors, with language ability and sex explaining relatively little of the total variability in play behaviors. Results are discussed considering the contribution that this type of study can make to theories of associations between childrenâs social development and social pretend play.LEGO Foundatio
Lexicality and frequency in specific language impairment: accuracy and error data from two nonword repetition tests
Purpose: Deficits in phonological working memory and deficits in phonological processing have both been considered potential explanatory factors in Specific Language Impairment (SLI). Manipulations of the lexicality and phonotactic frequency of nonwords enable contrasting predictions to be derived from these hypotheses. Method: 18 typically developing (TD) children and 18 children with SLI completed an assessment battery that included tests of language ability, non-verbal intelligence, and two nonword repetition tests that varied in lexicality and frequency. Results: Repetition accuracy showed that children with SLI were unimpaired for short and simple high lexicality nonwords, whereas clear impairments were shown for all low lexicality nonwords. For low lexicality nonwords, greater repetition accuracy was seen for nonwords constructed from high over low frequency phoneme sequences. Children with SLI made the same proportion of errors that substituted a nonsense syllable for a lexical item as TD children, and this was stable across nonword length. Conclusions: The data show support for a phonological processing deficit in children with SLI, where long-term lexical and sub-lexical phonological knowledge mediate the interpretation of nonwords. However, the data also suggest that while phonological processing may provide a key explanation of SLI, a full account is likely to be multi-faceted
Roadmaps to Utopia: Tales of the Smart City
Notions of the Smart City are pervasive in urban development discourses. Various frameworks for the development of smart cities, often conceptualized as roadmaps, make a number of implicit claims about how smart city projects proceed but the legitimacy of those claims is unclear. This paper begins to address this gap in knowledge. We explore the development of a smart transport application, MotionMap, in the context of a ÂŁ16M smart city programme taking place in Milton Keynes, UK. We examine how the idealized smart city narrative was locally inflected, and discuss the differences between the narrative and the processes and outcomes observed in Milton Keynes. The research shows that the vision of data-driven efficiency outlined in the roadmaps is not universally compelling, and that different approaches to the sensing and optimization of urban flows have potential for empowering or disempowering different actors. Roadmaps tend to emphasize the importance of delivering quick practical results. However, the benefits observed in Milton Keynes did not come from quick technical fixes but from a smart city narrative that reinforced existing city branding, mobilizing a growing network of actors towards the development of a smart region. Further research is needed to investigate this and other smart city developments, the significance of different smart city narratives, and how power relationships are reinforced and constructed through them
Prior history of feedingâswallowing difficulties in children with language impairment
Purpose
This study updated and extended our previous investigation (Malas et al., 2015) of feedingâswallowing difficulties and concerns (FSCs) in children with language impairments (LI) by using more stringent inclusion criteria and targeting children earlier in the care delivery pathway.
Method
Retrospective analyses were performed on the clinical files of 29 children (average age: 60 months, SD = 9.0) diagnosed as having LI using standardized testing, nonstandardized testing and final speech-language pathologist judgment. The files of children born prematurely or with a history of anatomical, structural, neurodevelopmental, cognitive, sensory, motor, or speech disorders were excluded. Literature-based indicators were used to determine the prevalence of difficulties in sucking, food transition, food selectivity, and salivary control. Values were compared with the general population estimate of Lindberg et al. (1992).
Results
A significantly higher percentage of histories of FSCs (48%) were found in the files of children with LI when compared with the population estimate (Ï2 = 13.741, df = 1, p < .001). Difficulties in food transition (31%) and food selectivity (14%) were the most frequent. Data confirm and extend our previous findings and suggest that a previous history of FSCs may characterize children with LI early in their care delivery pathway

Multilevel influences on resilient healthcare in six countries: an international comparative study protocol.
INTRODUCTION: Resilient healthcare (RHC) is an emerging area of theory and applied research to understand how healthcare organisations cope with the dynamic, variable and demanding environments in which they operate, based on insights from complexity and systems theory. Understanding adaptive capacity has been a focus of RHC studies. Previous studies clearly show why adaptations are necessary and document the successful adaptive actions taken by clinicians. To our knowledge, however, no studies have thus far compared RHC across different teams and countries. There are gaps in the research knowledge related to the multilevel nature of resilience across healthcare systems and the team-based nature of adaptive capacity.This cross-country comparative study therefore aims to add knowledge of how resilience is enabled in diverse healthcare systems by examining adaptive capacity in hospital teams in six countries. The study will identify how team, organisational and national healthcare system factors support or hinder the ability of teams to adapt to variability and change. Findings from this study are anticipated to provide insights to inform the design of RHC systems by considering how macro-level and meso-level structures support adaptive capacity at the micro-level, and to develop guidance for organisations and policymakers.
METHODS AND ANALYSIS: The study will employ a multiple comparative case study design of teams nested within hospitals, in turn embedded within six countries: Australia, Japan, the Netherlands, Norway, Switzerland and the UK. The design will be based on the Adaptive Teams Framework placing adaptive teams at the centre of the healthcare system with layers of environmental, organisational and system level factors shaping adaptive capacity. In each of the six countries, a focused mapping of the macro-level features of the healthcare system will be undertaken by using documentary sources and interviews with key informants operating at the macro-level.A sampling framework will be developed to select two hospitals in each country to ensure variability based on size, location and teaching status. Four teams will be selected in each hospital-one each of a structural, hybrid, responsive and coordinating team. A total of eight teams will be studied in each country, creating a total sample of 48 teams. Data collection methods will be observations, interviews and document analysis. Within-case analysis will be conducted according to a standardised template using a combination of deductive and inductive qualitative coding, and cross-case analysis will be conducted drawing on the Qualitative Comparative Analysis framework.
ETHICS AND DISSEMINATION: The overall Resilience in Healthcare research programme of which this study is a part has been granted ethical approval by the Norwegian Centre for Research Data (Ref. No. 8643334 and Ref. No. 478838). Ethical approval will also be sought in each country involved in the study according to their respective regulatory procedures. Country-specific reports of study outcomes will be produced for dissemination online. A collection of case study summaries will be made freely available, translated into multiple languages. Brief policy communications will be produced to inform policymakers and regulators about the study results and to facilitate translation into practice. Academic dissemination will occur through publication in journals specialising in health services research. Findings will be presented at academic, policy and practitioner conferences, including the annual RHC Network meeting and other healthcare quality and safety conferences. Presentations at practitioner and academic conferences will include workshops to translate the findings into practice and influence quality and safety programmes internationally
