The unprecedented growth of English and arrival of English as an International Language (EIL) has generated a new fledged argument about English language teachers’ role and status around the world. To date, much of the debate on the native/non-native distinction in EIL settings and factors contributing to sharpen distinctions has remained unsettled. This gap motivated this study on the English teachers’ grasp of their role and their stance in the EIL setting of Iran. For this purpose, this study adopted both quantitative and qualitative approaches to explore the nature of the English teachers’ attitudes through an EIL scale and teachers’ narrative accounts through Telegram groups. The three-level positioning analysis (Bamberg, 1997) of English teachers’ narrative accounts contradicted their perceptive evaluations of their status, as non-native English teachers. The results proved that, despite highlights of blurred distinctions, English teachers in Iran still believe that English belongs to the native speakers and position native speaker teachers as better models for pedagogical practices. The results have implications for teachers’ beliefs and the role of teacher education programs

Climatic events, especially severe droughts, have played a key role in cultural evolution and the challenge of civilizations. Climate change, which affects the natural resources and, consequently, the health and subsistence system of human societies, can lead to increased violence, migration, war, and the spread of epidemics. The main purpose of this study is to investigate the possible effects of climate on important events of the Sassanid era. Extensive regions of the Near East and Central Asia have been more vulnerable to droughts, which often recurred during cooling periods, due to semi-arid to hyper-arid environmental conditions. From the second half of the fifth century AD with the beginning of the cold event of the early Middle Ages, the occurrence of droughts and cold waves caused famines and epidemics. These tensions seem to have triggered many social and political events in the Sassanid realm and neighboring regions. These conditions in the sixth and seventh centuries AD caused the gradual decline and eventual fall of the Sassanid government due to Arab invasions. Historical and paleoclimate studies show that successive wars with Central Asian invaders in dry periods, and the frequent outbreak of plague associated with falling temperatures, especially following the floods of the Tigris and Euphrates rivers in AD 628, were affecting factors in the dynasty’s weakness and collapse. Besides, some civil wars and revolts, such as the Mazdaki movement, can be considered as indirect effects of climate tensions that contributed to the gradual decline of the Sassanid Empire.
