As a fascinating and colorful part of English language, idioms highly affect fluency, but they are quite difficult to teach and learn, and they have often been neglected particularly in ESL/EFL settings. Considering the large number of English idioms, corpus linguistics can be of great benefit in prioritizing materials in language classrooms based on the frequency information. Accordingly, the present corpus-based study aimed at identifying the most frequent idioms in English language by analyzing the data coming from the Corpus of Contemporary American English (COCA), composed of more than 520 million words. The study involved writing a special script using Hypertext Preprocessor (PHP) language which resulted in the development of five idiom lists, each containing 50 most frequently used idioms in each one of the five genres in COCA including academic, fiction, spoken, newspaper, and magazine along with their frequency of occurrences. Comparison was then made across the mentioned five genres. It was found that the spoken genre included more idioms whereas the academic genre was the least idiomatic. Furthermore, various levels of overlap was found among different genres. The least and the highest levels of overlap was found between the academic and fiction genres and between the magazine and newspaper genres respectively. The academic genre had more overlap with the newspaper and magazine genres. The findings can benefit EFL materials developers, teachers, and learners in recognizing and including frequently-used authentic idioms in language classrooms and textbooks.

Purpose: The aim of this study was to Presenting Human Resource Selection Model in Education with Tricycle Model. Methodology: This study was applied in terms of purpose and exploratory in terms of data type. The statistical population of the qualitative part of the research included university experts and senior managers of education and training of the whole country in the academic year of 2018-2019. Using the principle of theoretical saturation, 23 experts were selected based on purposeful sampling method. And the deputies of the Education Organization in the whole country were 900 people in 1397-98, and using the Cochran's formula, 270 people were selected based on the relative class sampling method. In order to collect the data, two interview tools and a researcher-made questionnaire including 87 items were used. Its validity was examined in three formal, content and structural methods and its reliability (Cronbach's alpha and hybrid reliability) was above 0.7. The data analysis method in the qualitative part of the theoretical coding was based on the method of basic data processing theory and in the quantitative part the methods of confirmatory factor analysis and modeling of structural equations were used using Lisrel-v8 software. Findings: According to the findings, the factors influencing the selection of human resources, including the behavior of the professional citizen, job performance and innovation, and the constituent components of human resource selection included, contextual, structural and behavioral components. Also, all the components identified in the current situation were evaluated as desirable. In addition, in this study, the mechanisms, contexts and barriers to human resource selection were identified. Conclusion: Strategies for developing an operational plan to improve human resource development in the education organization; Paying attention to meritocracy in delegating work responsibilities; Continuous evaluation of employee performance; The removal of infrastructure and credit barriers to staff access to Internet and scientific networks. Finally, it is possible to improve the choice of human resources according to the amount of components of the behavior of a professional citizen, job performance and innovation.
