Restructuring

Currently, distribution of various types of petroleum products is performed exclusively by the government. The high price of land in metropolitan cities, lack of incentive for the private sector to invest in construction of filling station due to the low-income, have caused filling stations to be insufficiently available. One of the solutions to overcome this obstacle is to use the ability of the private sector for distribution of petroleum products. To reduce the government's ownership, the market structure for petroleum products distribution in the country needs to be changed. This change should be firstly done gradually and step by step, and secondly, the government has to monitor this issue at various stages. In this study, three stages are proposed for the market restructuring of the petroleum products distribution in the country, and the conditions and requirements for each stage are separately identified. For the private fuel distributing companies, the most important problem is the economic issue and having profit. On the other hand, since the product price is still subsidized in the country, therefore, it is indispensable that the amount of commission fee should be determined in such a way that the activity for private companies is economically justified. In this study, the amount of products commision fee is calculated concerning capital and operatational expenditures, using the engineering economics method in different situations by COMFAR version 3 software.

Cross-linguistic influence is a documented cause of errors committed by second language learners. Since Talmy (2000) proposed two categories to classify languages of the world regarding their preferred lexicalization patterns of a literal motion event, known as verb-framed and satellite-framed languages, the effect of typological properties of the first language on second language acquisition specifically in the domain of motion expressions has been subject to extensive scrutiny. The present research examines whether the typological properties of Persian (L1) and English (L2) affect adult second language acquisition, particularly in the spatial domain comparing controls (English and Persian native speakers). To this end, three groups (every 25 members) of participants were asked to watch 12 short animated cartoons representing voluntary motion carried out in vertical and trajectory directions. The participants’ descriptions were recorded and analyzed regarding information density, semantic focus, and semantic locus of utterances. The findings of the research revealed that in spite of different lexicalization patterns to encode manner in English and Persian, Persian learners of English across two levels of proficiency, do not face challenges to lexicalize motion components in English, but they produce utterances with low density which is the typical way of focusing on spatial components in their native language, suggesting that the challenge learners face encoding motion events was not a linguistic issue, but rather a cognitive one. Persian learners’ use of English motion expressions regarding information density was more aligned with that of English motion expressions as they advanced to a higher proficiency level.
