Mastering writing has always proved an almost insurmountable barrier to EFL learners. In an attempt to alleviate problems advanced EFL learners have with writing, this study aimed at investigating the effect of scaffolded instruction through writing frames constructed from extended prefabricated lexical bundles. 40 female advanced English students, selected out of a population of 65, were randomly assigned into experimental and control groups. The participants of both groups were assigned a writing pre-test prior to any instruction, and a writing post-test following the twenty-session scaffolded instruction in both groups. The results revealed that the participants in the experimental group outperformed their counterparts in the control group as a result of the writing frames they were provided with. Overall, it is concluded that scaffolded instruction through writing frames can be a useful means of helping advanced students to improve their writing quality.

Two policies of carbon tax are considered by many countries for reduce carbon emissions. First policy emphasized on tax and second policy notice subsidy for carbon emission control. The results show that according to conditions, two policies can effective on reducing carbon emissions and technology development. A carbon tax Policy is needed to reduce carbon emissions in logistics systems. The purpose of this paper is to present effect of carbon tax policies for logistics in Iran pulp and paper industry. The research method is descriptive and data collection is survey, Samples consists two groups. The first group are experts for proposing possible Policy and deter-mining evaluation indices and selecting the appropriate Policy. The second group are managers in pulp and paper company for choose an appropriate Policy. Effect of factors on carbon tax was determined by experts’ interviews and fuzzy mean. Two suitable policies that covers the fossil fuels, were selected for simulation by VENSIM software. We considered 10 years for test and 10 years for simulation. Results showed both policies affect pollution reduction, reducing the fossil fuels consumption, reduction of emissions and increase innovation in the logistics system. The second policy that is carrying out carbon tax is more effective than the first policy which paying subsidies to reduce emissions.

This study aimed to evaluate the effectiveness of Sandplay Therapy on enhancing perceptual reasoning and neuropsychological functioning in children with Autism Spectrum Disorder (ASD). A randomized controlled trial design was used, involving 30 children aged 6-12 years diagnosed with ASD. Participants were randomly assigned to either the intervention group (n=15) or the control group (n=15). The intervention group received eight 90-minute sessions of Sandplay Therapy over two months, while the control group received standard care. The Wechsler Intelligence Scale for Children (WISC-V) and NEPSY-II were used to measure perceptual reasoning and neuropsychological functioning, respectively, at baseline, post-intervention, and five-month follow-up. Data were analyzed using mixed-design ANOVA with repeated measurements and Bonferroni post-hoc tests in SPSS-27. Descriptive statistics showed significant improvements in the intervention group for both perceptual reasoning (M=95.53, SD=7.48 at baseline to M=107.45, SD=8.21 post-intervention) and neuropsychological functioning (M=89.74, SD=6.95 at baseline to M=101.29, SD=7.56 post-intervention). Mixed-design ANOVA revealed significant main effects of time (F(2, 56)=30.15, p<.001, η²=0.52 for perceptual reasoning; F(2, 56)=32.75, p<.001, η²=0.54 for neuropsychological functioning) and group-by-time interactions (F(2, 56)=24.12, p<.001, η²=0.47 for perceptual reasoning; F(2, 56)=28.75, p<.001, η²=0.50 for neuropsychological functioning). Bonferroni post-hoc tests confirmed significant differences between baseline and post-intervention (p<.001) and baseline and follow-up (p<.001) for the intervention group. Sandplay Therapy significantly enhances perceptual reasoning and neuropsychological functioning in children with ASD. These improvements were sustained at follow-up, suggesting that Sandplay Therapy is an effective and sustainable intervention for this population.
