One of the disabilities that has rarely been studied in the field of observational learning is autism. the purpose of this study is to investigate the effects of watching a video model with different skill levels on learning a basketball skill in adolescents with autism. The current study is descriptive and causal-comparative. The subjects of this study consisted of 60 adolescents with autism with an age range of 13 to 18 years, and they were randomly and equally divided into three groups: skilled model, novice model, and control. The motor task involved a basketball throwing, in which the accuracy score was measured as the dependent variable. The subjects performed the pre-test (including ten throws), the acquisition stage (including 5 10-throws training blocks), and the retention test (including ten throws). Subjects in the observation groups watched their respective models for five times before each training block. Analysis of variance (ANOVA) was used to analyze the throwing accuracy. The results showed that novice video group had significantly better throwing scores than skilled video model and control groups in the acquisition phase and retention test. In addition, skilled group had significantly better throwing scores than control group in the acquisition phase and retention test. The results of this study show that people with autism benefit from watching a video model to learn a basketball throwing skill. This result may indicate that these people have the necessary mechanisms to learn new skills through video observation.

Lexical bundles are recurrent multi-word sequences that play a crucial role in academic discourse. This article presents an analysis of lexical bundles in book reviews across the disciplines of human and natural sciences. Drawing from a corpus of 737 book reviews, the study investigates the functional roles and structural patterns of these recurrent linguistic units. The research aims to bridge a gap in the literature by exploring how lexical bundles vary across disciplines. Employing a quantitative-qualitative approach, the study first quantitatively identifies the most common 4-word lexical bundles and compares their distribution between the two disciplines. The researchers then qualitatively analyzed the context in which these bundles are used, observing that they often serve to refer to or evaluate the structure, content, audience, or scope of the book under review. Findings reveal that while both human and natural sciences book reviews share some lexical bundles, they exhibit variations in their distribution, structures, and functions. Notably, natural sciences book reviews employ a greater frequency of lexical bundles signaling an evaluative context, particularly contexts related to the assessment of a book. The study also uncovers differences in the structural preferences of lexical bundles between the two disciplines. This research contributes to a deeper understanding of the genre-specific utilization of lexical bundles and underscores their role in conveying evaluative meaning in scholarly discourse. Furthermore, the study suggests avenues for further exploration, providing a foundation for future investigations into the intricate interplay between linguistic features and disciplinary preferences.

Absolving is one of the most important issues in Shiite texts and documents. There are some quotes in Shiite documents that clarify absolving Sunni Caliphs, especially first and second Caliphs. That is an important issue in the relations between Muslim branches. This paper tries to evaluate different quotes about absolving Caliphs in Shiite documents. It is done by analyzing library data. The results show that such quotes contradict the verse of Quran invites to unity, especial quotes about absolving, Ahl_al_beyt’s manner, the principle of piety and secrecy, etc., and are not validatable. Some of the reasons for the weakness of such quotes are hierarchy, the unreliability of some narrators, etc., which results through document analysis. Another result of analyzing quotes' origins is the invalidity of some primary sources. However, proving such an issue doesn’t mean denying the Caliphs absolving in Shiite beliefs. Avoiding to declare Caliphs absolving is very important, also swearing and slander.

There has been a debate over the use of genre-based pedagogy to develop university students’ ability to create valued meaning in academic writing. Some researchers support an implicit genre-based instruction while others support an explicit genre-based instruction. However, few empirical studies move beyond this debate to investigate the effectiveness of genre-based approach to developing university students’ academic writing skills. Therefore, this study investigates the impact of genre-based pedagogy in developing MBA students’ ability to construe critical stance in their writing. The data consisted of 28219 words corpus of 40 essay assignments, collected pre-genre-based course and post-genre-based course. Using Hyland’ s (2005) model of intersubjective positioning and Martin and White’s (2005) theory of evaluation in discourse, the data were analyzed for the distribution of hedges, boosters, attitude markers, and disclaim markers through manual coding using UAM corpus tool. The results showed a significant decrease in the use of key linguistic resources that function to make a text informal. In addition, the results showed a less significant increase and a less significant decrease in the use of key linguistic resources that function to construe critical stance in academic writing. These results have implication for the use of genre-based pedagogy in developing students’ ability to create valued meaning in academic writing. They show the extent to which genre-based pedagogy, implemented at the beginning or during subject learning, impacts students’ academic writing skills.
