The present study aimed to address an area of language learner strategies research which has not received the same attention as reading, writing, speaking, listening, and vocabulary strategies in spite of the significant role of grammar in the conceptualization of language competence. The paucity of empirical investigations in intervention research concerning grammar strategies was the impetus to carry out a grammar strategies-based instruction on the basis of several models including Oxford's strategic self-regulated model of learning to see its effects on learners' achievement of grammar across different age groups and proficiency levels. To this end, six groups of Iranian EFL learners, comprising 63 high school and 96 university students, were chosen from intact classes in Hamedan(Iran) for control and experimental groups. The treatment focusing on comparison of adjectives and adverbs, relative clauses, articles and prepositions continued for ten sessions after the administration of proficiency tests, pre-tests and immediate and delayed post-tests. The results of ANCOVA revealed meaningful differences between control and experimental groups. However, the variables of age and proficiency contributed to the significance of differences among the groups. Generally, the treatment proved to be especially useful for youngerlearners at lower proficiency levels. In addition, the delayed effect of the treatment was quite noticeable in all experimental groups. The findings stressed the usefulness of GSBI for EFL learners, which requires that teachers, material developers and syllabus writers consider the potentiality of such a strategy instruction for the development of EFL learners' grammar proficiency.

With the formation of local and national governments during the 3 rd -5 th centuries A.H. [9th - 11th A.D.], the circumstances were prepared for adaption and recreating cultural and artistic traditions of Sassanid period. In this regard, Samanid governors played a key role. Amir Ismail Samanid came up with a style which became a pattern for numerous mausoleums and on the other hand connected the architectural elements and designs of Sassanids with the Islamic era. The Mausoleum of Amir Ismail Samanid itself shows how the Sassanid architectural elements appear in a new format. Both the design and construction of this building appears to have been carried out objectively, and Amir Samanid had somehow intended to follow the Sassanid dynasty. Studying the architectural elements and features of the Ismail Samanids Mausoleum as well as adaptions from the Sassanid architecture, and also its historical and cultural contexts (the revival of Iranian identity and returning to the traditions of Sassanian, during the 3rd – 5th centuries A.H.) are the main objectives of the present paper.

From the middle of the first millennium BC, there witnessed a gradual bilateral relation between Iranians and Greeks. These people to people attachments also resulted in interactive influences between these two cultures and arts. Qualitative and quantitative investigation on these interactions is a basic issue in identifying both cultures. The current paper, among all miscellaneous influences of Hellenism on the culture and the art of the Parthian realm, attempts to analyze only the influences of basics and rules of the Greek aestheticism on the Parthian sculpture and come to a historical conclusion based on an inductive method.

Concerning its importance, present paper identifies the traits of Jihadi management in improving managers’ performance. Current study is a survey for which a questionnaire is used to gather data. To realize research aims, 384 middle and operational managers in companies and organizations in Tehran were considered as sample. Structural equation modeling (SEM) and confirmatory factors analysis (CFA) as well as LISREL and SPSS software packages were used to analyze data and to test research hypotheses and model. Research findings indicate significant impact by Jihadi traits such as “managers’ strong and good associations with employees”, “managers’ accountability and responsibility”, “obligation to commitments” , “authentication in affairs”, “designations” and “meritocracy” on managers’ performance.
