Purpose- Due to its special geographical location in the arid and semi-arid climate belt of the world, Iran suffers from water scarcity and limited usable water resources, notably considering the population growth and increasing demand for water and food. High water consumption in agriculture as one of the main water use sectors is estimated as 90% of total water, thereby necessitating consideration of water conservation methods. However, there are a number of barriers to use the current water conservation practices. Thus, the present study aims to investigate the barriers to equipping agricultural lands with the new irrigation technologies in Shahrabaad rural district, Bardaskan city. Design/methodology/approach- This is an applied study in terms of purpose and descriptive-analytical in terms of method, carried out using the random sampling method. The sample size was 338 households in the research area which was determined using Cochran's formula. Data were collected based on field and library studies. The validity of the questionnaire was confirmed by university professors and experts. The reliability coefficient of the questionnaire was 0.78 using Cronbach's alpha coefficient. Moreover, the TOPSIS fuzzy model was used to rank the villages in terms of the effect of barriers to using the new irrigation technologies, and SPSS software was used for analyzing the research questions. Findings: Results showed that the economic dimension was the most important barriers to using the new irrigation technologies. In addition, low-socioeconomic status of the farmers and small loans are the most prominent barriers to equipping agricultural lands with the new irrigation technologies in the research rural district. Research limitations/implications - unavailability of statistical information when referring to the agricultural jihad and the governor’s office, and completing the questionnaire, depending on the subject at the village level, is one of the main challenges of the present study. Practical implications - Given the specific research findings, it is necessary for agriculture and water policy-makers take serious measures concerning the incentive (low-interest and long-term loans, micro-land integration and the like) and punitive (imposing restrictions on traditional land users and stipulating other supports to change the irrigation method) instruments, because otherwise water restriction and the consequences of water scarcity will be challenging in  many areas and even may lead to a serious crisis. Originality / value: This study is prima facie significant in terms of statement of the reasons for the barriers to equipping agricultural lands with the new irrigation technologies from the users' perspective and then, in terms of a more detailed analysis of the research findings to change the implementation of traditional irrigation methods.

In Iran, most English teachers’ method of teaching writing is merely to have students do some writing exercises or simply to give them writing tests without any instruction, but writing is not an easy task for students, and teachers should be able to do more to facilitate their students’ writing. One of the ways to aid writing is dynamic assessment via graduated prompt. The graduated prompting procedure provides intervention in the form of predetermined standardized prompts that are sequenced from general to more specific. The present study aimed at investigating the effect of DA on the improvement of Iranian intermediate EFL learners’ picture-cued writing tasks. The study was conducted with 35 Iranian EFL learners (male and female) who were randomly selected from an available population pool of 70 EFL learners enrolled in two language institutes in Esfahan, Iran. The data were collected via a pretest, a posttest and a questionnaire. The analysis of the test scores through t-test revealed that the experimental group did statistically better in the test. Furthermore, almost all of the participants held positive attitudes toward writing, and their confidence in their own English writing ability increased. The implication of the study is that dynamic assessment via graduated prompt can be incorporated into the regular writing program.

Seas are the most important and unexplored and unknown ecosystems and the largest source of biodiversity on earth, which make up 90% of the biosphere. Therefore, it is necessary to preserve the marine environment as a precious asset and heritage against the damages caused by human activities, including international shipping. One of the international means to achieve this aim is the port state control (PSC) mechanism, PSC which is rooted in the traditional principle of free access of ships to the ports, also international conventions and regional memorandum of understandings )MoU’s( is considered complementary to the competencies of the flag state for environmental protection and maritime safety, allows the port states to assess the compliance of ships with relevant international and regional regulations, and to carry out a non-discriminatory inspection of foreign ships entering their ports. this paper review and criticize the role of current PSC mechanisms in the protection of the marine environment. To that end, use of the descriptive-analytical method to explaining the concept and legal foundations of PSC and the most important environmental challenges caused by the Increasing growth of international shipping and analyze the role of PSC. This study's findings provide that, the international PSC regime suffers some defects, accordingly to be more effective needs to mutation, in a way that includes new environmental damages, as well as, increase international convergence and integration in its Implementation This goal is achieved through the conclusion of a global MoU.
