In an expansive test of nations over distinctive geographic districts and over a long period of time, we discover restricted nation and variable-specific impacts of central bank straightforwardness on figure exactness and their scattering among an expansive set of proficient figures of monetary and macroeconomic factors. More communication indeed increments estimate mistakes and scattering. So the aim at this study is a systematic review of central bank transparency and capital market reaction. This study was conducted using a systematic review. At first all papers (n=165) related to keywords (capital market reaction and central bank transparency) searched for Persian and English databases; Google, Google scholar, PubMed covering the period from 2012 through 2022 was performed. Then all qualitative and quantitative papers related to central bank transparency selected and analyzed (n=28). As a result to inclusion and exclusion criteria, papers related to central bank transparency were found and analyzed (n=28). Predefined inclusion and exclusion criteria were: papers related to central bank transparency, papers were Persian and English, types of papers were original and all the papers were free full text. In the initial search, 165 papers were found that after reviewing the titles and abstract articles and removing repetitive and non-related, 54 possible related articles were investigated. Of these, 31 papers were omitted from the abstract because of lack of access to the original article and lack of sufficient information. Finally, 28 papers were included in the study. There are very few studies that have examined the effect of central bank transparency on capital market turmoil. The effect of central bank transpar-ency on the domestic capital market has not been studied. There is no agreement in the literature on theoretical discussions on whether increasing central bank transparency affects capital market turmoil. In foreign research, we can also refer to the study of Dinser and Eichngreen (2007) who have studied this effect empirically using the main transparency index. The pre-sent systematic review shows that almost whole of papers on central bank transparency and capital market reaction highlighted similar findings con-cerning monetary policy decisions.

An investment portfolio is a collection of financial assets consisting of investment tools such as stocks, bonds, and bank deposits, among others, which are held by a person or a group of persons. In this research, we use the Markowitz model to optimize the stock portfolio and identify the minimum spanning tree (MST) structure in the portfolio consisting of 50 stocks traded in the TSE. The observable which is used to detect the minimum spanning tree (MST) of the stocks of a given portfolio is the synchronous correlation coefficient of the daily difference of logarithm of closure price of stocks. The correlation coefficient is calculated between all the possible pairs of stocks present in the portfolio in a given time course. The goal of the present study is to obtain the taxonomy of a portfolio of stocks traded in the TSE by using the information of time series of stock prices only. In this research, report results obtained by investigating the portfolio of the stocks used to compute 50 stocks of the Iran Stock Exchange in the time period from January 2012 to October 2022.

In the second half of the fourth millennium BC. Southwest Asia underwent social changes, the result of which was the emergence of writing. In these developments, the cuneiform script in the south of the Mesopotamia and the Proto Elamite in the Iranian plateau progressed rapidly to such an extent that at the beginning of Elamite was scattered throughout the Iranian plateau. These writing systems were used for administrative and accounting purposes, and despite the fact that most of their signs are different from each other; there are important similarities between the two. Chalcolithic era, the best period in which you can see the idea of trading's and keeping of account; for the first time in this course, tools are seen which called them Token; it seems that the tokens in a variety of forms and counting symbols refer to a specific concept. The end of this period coincides with the Proto Elamites era in the south and southwest of Iran. Domestic production in the Neolithic period gave his place to the production of a workshop in the Chalcolithic era, which causes a lot of production. In the present study, firstly, will be investigated, small clay counters and then the Proto Elamite texts.

This study aimed to explore the combined impacts of critical thinking and dynamic Assessment on enhancing the writing performance of Iranian EFL learners, specifically focusing on teaching writing strategies. We selected 80 intermediate-level participants from a pool of approximately 200 language learners at an accredited institute (Gooyesh). These participants were divided equally into two experimental and control groups. The experimental group (EG) received writing strategies through the application of critical thinking principles and dynamic assessment. The control group (CG) received writing strategies through traditional methods without receiving critical thinking or dynamic assessment principles. The two groups underwent a writing pre-test to assess their initial writing skills, and after the treatment, to measure their writing improvement, they took a post-test using the same evaluation criteria as those of the pre-test. Then, appropriate statistical tools were employed to gauge the participants' writing progress as a result of the instructional methods. The results indicated that integrating dynamic assessment and critical thinking strategies significantly improved participants' written communication skills. These findings hold promise for EFL instructors, curriculum designers, and material developers.

Purpose- Rural tourism is considered a potential solution for rural communities to overcome economic challenges; in this context, smart tourism can be viewed as a logical advancement from traditional tourism, providing a balanced approach to revitalizing rural settlements and creating new economic opportunities for farmers and local communities.

The required information was collected through both documentary-library and field methods. The statistical population of the study includes 28 villages in Tafresh County. In the field method, a researcher-made questionnaire was used. For data analysis, exploratory factor analysis, one-sample T-test, and the MARCOS multi-criteria decision-making model were utilized.Findings - The results from the exploratory factor analysis indicated that among the five identified factors, social and infrastructural factors in smart tourism have the greatest impact on the sustainable development of rural businesses. The results from the MARCOS decision-making model also showed that the villages of Kookan, Khank, and Naqousan are in a more favorable position regarding the indicators of smart tourism in the sustainable development of rural businesses.
