using crop simulation models is an efficient complement to experimental research. crop models can also be helpful with respect to decision-making in sustainable farming system. this study was done to estimate genetic coefficients and evaluate performanced dssat in prediction of development, growth and yield in wheat. data from various field experiments for four wheat cultivars koohdasht, shirou...

Chinese tone has played an important role in the development of phonological theory from distinctive features and autosegmental phonology to Optimality Theory and its various adaptations. This article reviews some past and current issues in the analysis of Chinese tone and points out how the development of theoretical phonology has shaped the highs and lows of this research enterprise. To fruit...

PURPOSE This study involved prospective longitudinal data on 5 late talkers to provide information about the course of phonological development in order to identify possible predictors of delayed versus deviant development. METHOD Five children (3 boys, 2 girls) were identified as late talkers and divided into a younger group and an older group. Each child was followed monthly for 10 to 12 mo...

This longitudinal study explored the importance of kindergarten measures of phonological awareness, working memory, and quantity-number competencies (QNC) for predicting mathematical school achievement in third graders (mean age 8 years 8 months). It was found that the impact of phonological awareness and visual-spatial working memory, assessed at 5 years of age, was mediated by early QNC, whic...

Explicit phonological awareness instruction in preschool curricula has been established as playing a fundamental role in improving reading outcomes in children (Carroll, Snowling, Stevenson, & Hulme, 2003). However, to date, there has been a lack of evidential research data that assess the value of incidental phonological awareness instruction as a supplement to regular instruction within these...

INTRODUCTION Although attention deficit hyperactivity disorder (ADHD) is usually associated with language disorders, there are few studies of phonological processing and the efficacy of psychostimulants (methylphenidate) on this. OBJECTIVE 1. To find whether there are differences in the development of phonological processing, evaluated using linguistic segmentation tests and tests of lexical ...

BACKGROUND phonological awareness abilities of children with a history of speech-language disorders. AIM to compare the phonological awareness abilities of individuals who recovered from phonological disorders after having gone through speech-language treatment with that of individuals with typical phonological development. METHOD participants of this study were eighteen individuals, nine i...
