Purpose- One of the most important strategies facing drought and agriculture water shortage in North-West Iran is developing pressurized irrigation systems (PISs). In this regard, the present study aims to investigate the factors determining the adoption of the PISs by farmers in Ardabil Province. Design/methodology/approach- First, by drought zoning of Ardabil Province (by SPI method and GIS software), three regions including regions with mild, moderate and severe drought levels were determined. In the second step, using multi-stage cluster sampling, adopter and non-adopter farmers of the PISs were selected from three regions of study (n= 415). Also, the logistic regression was used to determine the affective and distinctive factors of farmers' groups. Findings- According to the results of logistic regression analysis, the predictive power of model was 0.622 and the sensitivity of the regression model to determine the model validation was obtained as 85.8%. Also, from among 17 factors of study, 7 factors of education level, farm income, knowledge about the PISs, the infrastructure for PISs, the effect of local weather conditions, the trust towards the optimality of PISs and the improvement in farm water management, positively impacted on the adoption and use of PISs. Among effective factors, knowledge about the PISs (Wald: 32.676), the trust towards the optimality of PISs (Wald: 27.855) and the infrastructure for PISs (Wald: 21.648) were the most important factors predicting to the decision to adopt and use PISs among farmers. Research limitations/implications- Since the study was carried out in a large area of the province, accessing the farmers and experts in the Ardabil Province was difficult and time consuming. Practical implications- The agricultural extension and education programs and PRA method, can provide the basis for the adoption of PISs among most of the farmers. Also, the infrastructure programs for the implementation and setting up of PISs are the priority of governmental projects to develop the PISs in the regions of the study. Originality/value- It seems that identifying and providing the necessary infrastructure for implementing pressurized irrigation programs should be based on the scientific needs assessment of the agricultural fields’ conditions in different regions. Also, proper the appropriate government funding and financial support for the appropriate infrastructure of PISs will increase the willingness of farmers to adopt and use of the PISs.

This study aimed at identifying the ethical challenges encountered when developing a language education virtual environment that acts as a smart platform for managing reading comprehension instruction for EFL/ESL learners. Since Reading Instruction Management System (RIMS) is going to observe, monitor, and supervise the learners' out-of-class activities and help teachers improve their teaching quality, it has to seriously handle humane elements which have not been seriously debated in the related literature on language education software development so far. To this end, this study has devised a qualitative study to further explore the aspects of ethical considerations that have to be considered when developing technological aid. Accordingly, 14 teachers and 14 students were selected based on the purposive sampling method concerning the condition that they will be among the teachers and learners who will use RIMS when it is officially launched in the institution. They were asked to take part in interviews which were held on a one-on-one basis and in Persian, the participants' mother tongue. The data were codded and the emerged ones were then classified under four themes including the challenges related to the teachers, learners, and institutions. Each of these has several aspects which are discussed, accordingly.

Human language and power of speech are not the only means of his communication with others, but a high percentage of his messages are transmitted to others willingly or unwillingly with other parts of the body and through his physical movements and behaviors, which is called body language. The messages sent by body language are much more expressive and expressive than the messages that are transmitted through speech. Imam Khamenei (Madazla-ul-Ali) has proven during his leadership and in various scenes recorded by him that he is very skilled and capable in using body language. On the other hand, one of the foundations of personality psychology is that people's movements and behavior are subject to their personality. Therefore, this research seeks to introduce the scientific and Quranic personality of the Supreme Leader, using library sources and descriptive and analytical methods to analyze the origins and Quranic foundations of Imam Khamenei's different body language in meeting with the people and leaders of some countries to pay The findings of this research indicate that the origin of his humble and kind body language in front of the people, especially the families of the martyrs, as well as his authoritative and seemingly arrogant body language, in meeting with some heads of government, are both humanizing and sublime commands of the Holy Quran.
