This article investigates the financial convergence between Iran, OPEC & the Shanghai Organization trade groups, of which Iran is a member.  The analysis covers the period of 2005 to 2017.In order to examine the convergence dynamics of these financial markets; we have employed the Philips and Sul (2007) methodology, which uses a nonlinear time-varying factor model. This paper provides a comprehensive picture of the financial systems within Iran and its convergence clubs by testing the convergence of their money market with domestic credit to private sector by banks (% of GDP), deposit and lending interest rate, real interest rate, and capital market with Stocks traded, total value (% of GDP). The empirical findings show that money and stock markets of OPEC and the Shanghai group do not form a homogenous convergence club. Results show that Iran has convergence with some countries in OPEC and the Shanghai group in money and stock markets, which can be explained by their similar economic indicators in both markets. Furthermore, the convergence speed between Iran and the Shanghai countries is higher than that of Iran and OPEC countries, which proves that joint trade agreements are stronger reasons for convergence than the oil factor. Iran should implement further structural reforms in order to achieve greater financial convergence with its joined groups.

The purpose of this research is to design a comprehensive model to prevent price manipulation in the Iranian capital market. The approach used in this research is qualitative and has been used as the research method from the theory of grounded data (grounded theory). The data collection was done in depth and open interviews with 26 capital market elites and professors and students from different universities. For data analysis, the comparison method has been used during three stages of open, axial and selective coding. With regard to the analysis of data, we have found that the comprehensive model for preventing price manipulation consists of six main categories, including regulatory mechanisms, legal mechanisms, educational mechanisms, cultural mechanisms, structural mechanisms and implementation of the pattern of prevention. The price manipulation is explained in detail. Finally, the circumstances, the conditions of the intervention, the conditions governing (strategies), the strategies and the consequences have been identified.

Motivated by the concept of Communicative Language Ability and the eminence of the IELTS exam, this study intended to scrutinize the representation of functional knowledge (FK) and socio-linguistic knowledge (SK) as sub-components of pragmatic knowledge in the writing performances of both tasks of the online General IELTS-practice resources across three band scores. This quantitative inter-scores/intra-tasks and inter-tasks investigation aimed to reveal firstly whether the writers of three band scores 7, 8, and 9 differed from each other in their FK and SK level, and secondly whether the tasks differed in activating them. This study adopted a taxonomy of five illocutionary acts and 20 register features to investigate representation of FK and SK in a well-established corpus of 180 writing performances through both manual analysis and Multidimensional Analysis Tagger software. While the results of statistical analyses revealed no FK differences between the bands in task one (T1), T2’s higher bands involved more functional features because of the expression of a diverse range of psychological states, no speaker’s involvement, and less commitment to a future course of actions. Furthermore, socio-linguistically, band 9 scripts encompassed more logical relations, but conversational and spoken style in T1 and more integration, less simplified structures and ego-involvement in T2. The inter-task analyses uncovered T1’s greater activation of FK through self-mentions, others involvement, emotion, and intention expression. Nevertheless, when it came to SK register features, T2 overdid in both spoken and written genre elements except in persuasion, writers’ involvement, mental acts expression, and interactive discourse creation.
