One of the most important issues in the economy is the role of government in the process of eco-nomic growth and development. Production is a complex and social activity that requires all its con-texts and resources to achieve proper production for society. Therefore, the issue of importance is the manner and quality of government intervention in matters related to the economy and the wel-fare of the people, not the extent of this intervention. In Iran, there is always disagreement among thinkers on which institution is responsible for development. For some, the government has a duty to take the lead in development and to push it forward, but for others, the government is not a good institution to promote development. These groups play a minimal role for the government. This study, by comprehensively examining these two different approaches, examines the views and ideas of three prominent scientists and experts in the field of political economy and focuses on the role of government in development. Azimi introduced development in a more general way and believed that complete development is not possible without the development of all structures. According to him, in the developed world, structural guidance (structuring in the presence of technical domi-nance) is unnecessary and short-term guidance is necessary. The importance of the government in the development process is so great in the idea that the main and most important institution of de-velopment is the "government based on democracy"; And he puts the judiciary and the media in the next ranks. Reiis Dana considers the state to be class in nature and does not examine the state sepa-rately from the global relations of capitalism. This lack of attention has always caused development in a fragmented, unbalanced and unsuccessful country. According to Reiis Dana, development in Iran is due to the development of capitalism, because capitalist development in the world is growing unevenly. Nili believes that government intervention in development, in addition to inefficiency, deprives people of their freedoms. Therefore, Nili looks at the issue from another angle and defends government restrictions on the economy and development by prioritizing freedom over social jus-tice.

Nowadays, financial markets and especially the stock market are important and undeniable sources of financing for investment toward the economic growth and development of countries. These markets also have a tangible role as a basis for implementing monetary policy. This study aims to investigate the effect of monetary volatility on the seasonal performance of the Iranian stock market from April 2001 to March 2021.The TEDPIX index of the Tehran Stock Exchange was used for designing and explaining the research model for measuring monetary policy uncertainty in terms of the debt of banks to the Central Bank and to measure the Iranian stock market’s performance. With portfolio theory as the theoretical basis for the study, the housing price index and the exchange rate were added to the research model as other independent variables due to their importance to the portfolio of individuals. In this regard, monetary policy uncertainty was first calculated using the exponential general autoregressive conditional heteroskedastic (EGARCH) method. Then, the effect of uncertainty on the TEDPIX index was calculated using the vector auto regression (VAR) statistical method in EVIEWS 12. The findings indicate a significant negative correlation between monetary policy uncertainty and short and long term TEDPIX index. Moreover, exchange rate and housing price index has a significant positive effect on the TEDPIX index.

Listed companies are always affected by shocks and instabilities in parallel financial markets such as exchange rates and gold. Knowledge of how these impacts are useful for managing companies and investors to make optimal decisions regarding risk management, financing and investment. Therefore, in this study, the effect of investigating the asymmetric effects of parallel financial markets shock on stock returns and financial and commercial risk of 262 companies listed on the Tehran Stock Exchange during the period 2009-2010 using the Generalized Torque (GMM) approach. Been investigated. The results show that the negative and positive shocks of the exchange rate and the price of gold have an asymmetric effect on trade risk, finance and stock returns. These asymmetric effects apply in terms of size, sign and significance. Positive gold price shocks also have a negative effect on trade risk and a positive effect on financial risk, but these shocks do not have a significant effect on stock returns. In contrast, the impact of negative gold price shocks on financial risk is negative and market returns are positive (the impact of negative shock on trade risk is not statistically significant). Based on the above results, it can be stated that corporate operating costs and financing costs are affected by price shocks in the gold and foreign exchange markets.

In the literature of school leadership, two perspectives often conflict. The first is a rational perspective that focuses on the truth-seeking and truth-accepting nature of humans, while the second is a political perspective based on the premise that different groups within a school have varied interests and desires, which they pursue through power struggles. This research aimed to examine these two perspectives in schools to determine which can explain the mechanisms of the school. To achieve this goal, an explanatory mixed-methods strategy was employed. In the first phase of the research, quantitative data were collected to compare and measure the effectiveness of school principals in regular and gifted schools in Kashan. For this purpose, one exemplary school and eight public (regular) schools were selected using stratified sampling. The quantitative data collection tool was Parsons' standard questionnaire for school management effectiveness. The results of the quantitative phase indicated that the management of exemplary schools was more effective than that of public schools. In the second phase, a phenomenological strategy was used to explore whether public school principals accepted that these findings could be utilized in educational policy-making. In this section, eight public school principals were selected and interviewed. The results showed that none of the public school principals, contrary to the assumptions of the rational perspective, accepted these findings, and they employed various political strategies to defend their performance. These findings suggest that the political perspective can explain many realities of school management.

This study explored the use of meta-cognitive strategies (MCS) in reading comprehension among Iranian EFL learners with varying levels of proficiency (i.e. high proficient vs. low proficient). Furthermore, there was an attempt to investigate the impact of motivation on language learners’ MCS use. The proposed hypotheses predicted: 1) there is no significant difference between the high proficient EFL learners’ use of MCS compared to their low proficient peers, and 2) there is no relationship between the two groups’ MCS use and their motivation. One hundred participants, aged 16-24, were selected from the intermediate and advanced EFL learners in Jihad Daneshgahi Institute of Kermanshah. The data was collected through: a) a modified version of the FCE reading paper, b) a modified version of the PET reading paper, c) Taraban's (2006) MCS Questionnaire, and d) an adapted form of Gardner's (1985) motivation questionnaire, and was submitted to a series of independent samples t-test and co-relational analysis. The results indicated: 1) a significant difference between the two groups in terms of the use of meta-cognitive strategies, favoring the highly proficient readers, and 2) a significant relationship between the use of meta-cognitive strategies and motivation of the participants.

Oral participation (OP) in class is an important factor contributing to the development of oral fluency. Recent studies in language learning have addressed the necessity of classroom interaction, or rather students’ oral participation in class. A correlational research study was drawn upon to measure the oral participation and factors affecting oral activities of the ELT students studying at the M.A. level at Islamic Azad University of Ardabil in Iran. An initial pool of 93 participants was selected through purposive sampling. The data analysis was conducted using structural equation modeling (SEM). The results obtained indicated that there is a significant relationship between social and educational factors relative to the oral activities of EFL learners. The findings also showed that in oral participation, educational factors play the most important role in controlling the OP content.
