Stability, change, and correlates of the peer relationships of young children with mild developmental delays

The peer relationships of young children with mild developmental (cognitive) delays recruited at 4-6 years of age were examined in a longitudinal study across a 2-year period. Results revealed only modest increases in children's peer interactions, a high degree of intraindividual stability, and the existence of a poorly organized and conflict-prone pattern of peer interactions. Child cognitive and language levels as well as family stress and support were associated with children's peer interactions. A subgroup was identified of initially low interactors who were at especially high risk for future peer interaction problems. These findings further underscore the importance of designing and implementing early intervention programs in the area of peer relationships for children with mild developmental delays.     

Aluminium tolerance in barley （Hordeum vulgare L.）： physiological mechanisms, genetics and screening methods

Aluminium （Al） toxicity is one of the major limiting factors for barley production on acid soils. It inhibits root cell division and elongation, thus reducing water and nutrient uptake, consequently resulting in poor plant growth and yield. Plants tolerate Al either through external resistance mechanisms, by which Al is excluded from plant tissues or internal tolerance mechanisms, conferring the ability of plants to tolerate Al ion in the plant symplasm where Al that has permeated the plas- malemma is sequestered or converted into an innocuous form. Barley is considered to be most sensitive to Al toxicity among cereal species. Al tolerance in barley has been assessed by several methods, such as nutrient solution culture, soil bioassay and field screening. Genetic and molecular mapping research has shown that Al tolerance in barley is controlled by a single locus which is located on chromosome 4H. Molecular markers linked with Al tolerance loci have been identified and validated in a range of diverse populations. This paper reviews the （1） screening methods for evaluating Al tolerance, （2） genetics and （3） mechanisms underlying Al tolerance in barley.     

Testing the double-deficit hypothesis in an adult sample

The double-deficit hypothesis of dyslexia posits that reading deficits are more severe in individuals with weaknesses in phonological awareness and rapid naming than in individuals with deficits in only one of these reading composite skills. In this study, the hypothesis was tested in an adult sample as a model of reading achievement. Participants were parents of children referred for evaluation of reading difficulties. Approximately half of all participants reported difficulty learning to read in childhood and a small subset demonstrated ongoing weaknesses in reading. Structural equation modeling results suggest that the double-deficit hypothesis is an accurate model for understanding adult reading achievement. Better reading achievement was associated with better phonological awareness and faster rapid automatized naming in adults. Posthoc analyses indicated that individuals with double deficits had significantly lower reading achievement than individuals with single deficits or no deficits.     

Examining the public face of academic development

Language is an important way of presenting an identity, either individual or group. This paper explores the language used in the presentation of the identity of academic development. The study is based on an analysis of websites from academic development centres in the UK and Australia and outlines the public ways in which academic developers present their work and the meanings that are attached to this presentation. It uses frame theory to analyse the language of academic development websites in order to explore some of the assumptions underpinning the public face of academic development. It explores the ways in which language is used to frame and persuade in order to establish the credibility of academic development as an expert and scholarly field.     

The Staff Conference: A Medium for Staff Development

Solihull's development of delegated budgets began in 1981. The experiences of schools and Centre led to the acceptance by Council in 1987 of a scheme for general implementation. The detailed scheme is included in an Appendix to the article, together with examples of vital financial management systems. In his article, the Director of Education explores the effects of delegation of the budget, and with it, the decision‐making process. The school heads’ role gains the natural extension of facility to implement management decisions, but what of the role of the Centre?     

The effect of music therapy services on classroom behaviours of newly arrived refugee students in Australia—a pilot study

This pilot study examined the effects of a short‐term music therapy program on the classroom behaviours of newly arrived refugee students who were attending an intensive ‘English as a Second Language’ secondary school. A cross‐over design with two five‐week intervention periods was employed with group music therapy sessions conducted one or two times per week. Data from the Behaviour Assessment Scale for Children were used to evaluate a range of positive and negative school behaviours. A significant decrease in externalising behaviours was found with particular reference to hyperactivity and aggression. No significant differences were found in other behaviours. Explanations and implications of these findings are discussed.     

Translanguaging: origins and development from school to street and beyond

The article traces the Welsh origins of “translanguaging” from the 1980s to the recent global use, analysing the development and extension of the term. It suggests that the growing popularity of the term relates to a change in the way bilingualism and multilingualism have ideologically developed not only among academics but also amid changing politics and public understandings about bilingualism. The original pedagogic advantages of a planned use of translanguaging in pedagogy and dual literacy are joined by an extended conceptualisation that perceives translanguaging as a spontaneous, everyday way of making meaning, shaping experiences, and communication by bilinguals. A new conceptualisation of translanguaging is in brain activity where learning is through 2 languages. A tripartite distinction is suggested between classroom translanguaging, universal translanguaging, and neurolinguistic translanguaging. The article concludes with a summary of recent research into translanguaging with suggestions for future research.     

Assessment of Early Developing Phonological Awareness Skills: A Comparison of the Preschool Individual Growth and Development Indicators and the Phonological Awareness and Literacy Screening–PreK

Research Findings: Assessing the development of early literacy skills is necessary in order to identify children with delays, provide appropriate intervention, and monitor progress. The purpose of the current study was to compare the data obtained from 2 curriculum-based assessments of phonological awareness skills in a sample of low-income, urban preschoolers. Participants included 227 children from Head Start and other community-based preschool classrooms located in a midwestern city. The Preschool Individual Growth and Development Indicators (IGDIs) and the Phonological Awareness and Literacy Screening–PreK (PALS-PreK) were administered in the fall and spring of the year. Results suggested that the PALS-PreK was more advantageous than the IGDIs in terms of providing meaningful data for this group of children. The IGDIs appeared to be more appropriate for developmentally advanced preschoolers in this population. Practice or Policy: There remains a critical need for assessments of emergent literacy that are appropriate for diverse groups of preschool children and can feasibly be used for monitoring development.     

Understanding and Improving Classroom Emotional Climate and Behavior Management in the “Real World”: The Role of Head Start Teachers' Psychosocial Stressors

Research Findings: This article reports on two studies. Study 1 considered ways in which Head Start teachers' (n = 90) psychosocial stressors are related to teachers' ability to maintain a positive classroom emotional climate and effective behavior management in preschool classrooms. Study 2 tested the hypothesis that among teachers randomly assigned to a treatment condition (n = 48), psychosocial stressors serve as important predictors of their use of an intervention designed to improve classroom emotional climate and behavior management. Practice or Policy: Findings from Study 1 were mixed; notably, teachers' personal stressors were moderately predictive of lower use of effective strategies of behavior management in the classroom. Findings from Study 2 suggest that psychosocial stressors are not a barrier to teachers' use of intervention services. Contrary to our expectations, teachers reporting more stressors attended more training sessions than did teachers reporting fewer stressors. Teachers reporting higher levels of stress availed themselves of less support from mental health consultants during classroom consultation visits offered to treatment group classrooms as part of the intervention.
