Many studies have been conducted on the ways of promoting willingness to communicate in learners in EFL/ESL contexts. While different scholars have undertaken studies on many of these variables, few of these studies have aimed at EFL university students in Iran. This study reports on the role of international posture and perceived communication behavior on Iranian EFL learners’ communication in English. The participants who accepted to attend the survey completed questionnaires on WTC, international posture and perceived communication behaviors. The results driven based on this research indicated that Iranian English BA students are generally tended to speak in English. The participants' willingness to communicate in English was found to have a significant relationship with their perceived communication behaviors and international posture. The findings of this study will be beneficial for various policy makers and practitioners, including those dealing with curriculum development and teacher education to focus more on the elements influencing communication in English.

This study investigates how L1 Chinese scholars in hard science disciplines use metadiscourse in their English academic writing, by comparing the deployment of metadiscoursal resources written by L1 Chinese and L1 English scholars. Hyland’s (2005) interpersonal model of metadiscourse was adopted for the analysis. We found that L1 Chinese scholars used less metadiscoursal resources than L1 English scholars on the whole. In the two dimensions of interaction, L1 Chinese scholars made more use of interactive devices, while L1 English scholars used more interactional items. This reflects that L1 Chinese scholars made greater efforts to guide the readers through their papers, and L1 English scholars are more concerned with creating author identity and engaging their readers. The t-tests confirmed that L1 Chinese scholars used significantly more code glosses in interactive metadiscourse and less self-mentions in interactional metadiscourse. An in-depth analysis reveals two functions of code glosses and five functions of self-mentions in RA abstracts.

This study aimed to evaluate the effects of environmental policies including price and non-price policies on natural gas demand in Iranian industrial sector. For this purpose, considering the dynamic nature of our panel data, we adopted Generalized Method of Moments (GMM) method to estimate natural gas consumption for 22 Iranian industries from 2005 to 2015. The results illustrated that the annual average of natural gas consumption has been rising, reaching five times higher than the consumption of other fossil fuels. Among the industries, other non-metallic minerals industry with 8 percent of the total production and more than 25 percent natural gas consumption have been regarded as the most natural gas consumer industry. The results of our GMM model showed that non-price environmental policies are more effective than the price policies on natural gas consumption. Overall, in non-price policies, energy intensity seems more important comparing to CO2 emission reduction. We recommend that governmental energy policies should focus more on energy intensity improvement in Iranian industries through technological enhancement and fuel energy saving regulations.

Overconfident managers, who tend to overestimate their capabilities, underestimate the possibility and impact of side effects in projects. The purpose of this study is to review the effect of managerial overconfidence on research and development expenditures and the moderating effect of firm value and liquidity on this relationship. For this purpose 51 companies were chosen from oil/gas, and petrochemical Companies listed on the Tehran Stock Exchange over the period 2012-2017. This research, within three basic hypotheses, is analyzed by Eviews software and shows that managerial overconfidence has positive effect on research and development. Company liquidity has direct effect on relationship between managerial overconfidence and R&D, but firm value has no meaningful effect on the relationship between managerial overconfidence and R&D. <strong>Keywords</strong>: managerial overconfidence, R&D, liquidity, firm value
