This study tries to identify the structure of global date market under the concentration indices. The results made by indices of   and  show that during the period of 1990 to 2009, their values increased from 1292 to 1466 and from 63 to 67, respectively. It reflects that the inequality intensity of market distribution has grown while the number of exporters is expanded at this time. So, it can be concluded that the new exporters who have entered to the market had a small share and didn't have an ability to reduce the distribution of market share of major exporters. The degree of competition (term CQ) in the market has declined from 37 percent in 1990 to 33 percent in 2009. Based on these indicators, it can be deduced that the policies adopted by the major countries of the market have been in such a way that they have maintained their dominant position and have reduced the share of competitors. The findings also indicate that the global market concentration has no significant effect on Iran-date foreign exchange earnings while exchange rate, production, and price have a significant impact on the foreign earnings.  JEL Classification: F12, D43, F16.

One of the essential problems of urban planning and management in Iran is the failure of implementation and execution of urban development plans. The studies show that lack or poor level of citizen participation is one of the influential reasons to that. So, it is evident that there is a need for “bottom-up” and “community based” sustainable solutions for urban problems. Asset-Based Community Development (ABCD), as an alternative to the commonly need-based approach, is based on identifying and mobilizing assets and capacities (although not being very much) in communities and emphasizes on participation in order to accelerate development. This paper would review the application of ABCD approach and evaluation its efficiency in a residential deteriorated neighborhood of Tehran (Emamzadeh Hassan Mohalla), with specific spatial characteristics and religious background, which is now housing the low class of blue collar workers and losing its population due to deterioration of social condition and physical quality. The results, based on survey, random sampling and statistical analysis, show that social and physical capitals (as the main community assets) have increasing effect on organized participation tendency (as the main goal of ABCD). Subsequent analysis showed that social capital is a direct factor to increase organized participation tendency and consequently neighborhood development, and physical capital, as an indirect factor, serves to increase social capital. Therefore by applying this approach for development, people-based strategies (to enhance participation) and place-based strategies (to enhance social capital), should simultaneously be considered.

This research is to analyze the effects of Critical Discourse Analysis (CDA) on reading comprehension of Iranian EFL learners. After providing a useful synopsis, this research is to contextualize CDA in two ranges of learning situations and classifies how CDA can shed new perceptions on learning. Detailed systematic measures are included to clarify the procedure of conducting CDA. The participants were 61 male and female M.A. English students of Boroujerd Islamic Azad University, selected on a non- random basis by applying a TOEFL test among over 91 EFL M.A. students considered to be at the same level. Those whose scores on the test were from 224 to 316 with the mean of 273.736 were considered as the participants of this study. They had received instructions on English language for 16 sessions at Boroujerd Islamic Azad University. The participants were native speakers of Farsi. Any word, phrase, or structure can have different possible meanings, which is known as the meaning range. Focusing on the implied meaning of the text, the learners of the second language reach a better understanding of the text and consequently of the second language. The present research shows how seven elements offered by Fairclough's model in critical discourse analysis can affect reading ability of Iranian EFL learners. Also,besides scrutinizing the effect of CDA in EFL learners, the researcher introduces the seven elements of Fairclough's model as well.
