The supply of natural gas in energy exchanges has emerged as a significant aspect of the global energy landscape since the 1990s, requiring the establishment of appropriate trading platforms. In Iran,  it was envisioned the sale of up to ten billion cubic meters of natural gas following the approval of the budget law of 1400 (2021). However, despite these projections, no offerings were made on the Iran Energy Exchange (IRENEX) due to various challenges. This research aims to identify the essential prerequisites for gas supply in energy exchanges using a systematic review approach and subsequently analyze these prerequisites within the context of Iran's gas market. The findings of this study reveal that while the technical prerequisites for such transactions are presently available, significant strides are needed in terms of legal and structural aspects. Notably, challenges arise from the presence of long-term contracts between the National Iranian Gas Company (NIGC) and neighboring countries, the monopolization of the country's natural gas industry's value chain by state-owned enterprises, incomplete unbundling of the mentioned chain, limited third-party access to pipelines and storage facilities, gas supply with subsidized tariffs, and the absence of a comprehensive law governing the integration of Iran's natural gas market. Overcoming these obstacles is imperative for enabling natural gas supply in the IRENEX and successfully implementing the gas supply program. Policy makers must carefully address these prerequisites to foster a conducive environment for gas trading within the energy exchange and pave the way for its effective implementation.

Considering the long-term nature of oil and gas contracts, managing the relationship between the parties to the contract is fundamentally important. In upstream oil contracts, according to the level of supervision and control of the host state over the petroleum project, the level of communication is variable. In risk service contracts due to extensive supervision, there should be a lot of interaction and cooperation between the parties. This study examines Kuwait's model of technical assistance services contracts. It concludes that, due to its improved cooperative structure, this format of service contracts is more compatible with current conditions in Iran's oil fields, such as southern Pars. These fields are operated by Iranian oil companies, but need more technology to function properly. In this article, it is discussed how Technical Assistance Contracts (TACs) can generate an efficient solution for the issue at hand. The methodology is based on describing and analyzing Kuwait’s TAC.

Performance management is a systematic approach that helps to improve the organization's performance through the processes of setting strategic goals, measuring, collecting, and analyzing data, reviewing performance data reports, and applying its results. An evaluation and monitoring system in the form of performance management At the macro level, which monitors the upstream documents, development plans, etc. in the form of one-year or even fewer time schedules, and provides the necessary feedback to pave the way to achieve the vision at different structural and management levels, one of the necessities which is currently the main question of the research entitled "Which is the appropriate model for managing the performance of managers?". To achieve this goal, the factors were identified using a qualitative and quantitative combined approach. In the qualitative phase of the Systematic literature method (SLR) and Delphi technique. The articles and documents selected in the systematic literature method (SLR) were evaluated in terms of quality through the CASP method. Based on the findings, 6 factors were identified as effective factors on performance. Managers were identified as external organizational factors - internal organizational factors - individual factors - input elements - performance management processes - results. Each of these factors has been used separately or in combination in various articles and research.

Commodity Exchange Traded Funds (ETF) are one type of ETF that underlying assets are agricultural products, energy or metals instead of stocks. These ETFs expose their investors to the market of various commodities in different ways, such as physical commodity, futures of single commodity, futures of baskets commodities, equities with exposures to commodities in various forms. In recent years, this financial instrument has become one of the important investment options among several people by creating many advantages. Despite these developments, scarce evidence exists in the current literature on the feedback trading of ETF investors. The objective of this paper is examination of feedback trading in behavior investors of Saffron ETF in Iran. For this purpose, daily data of two Saffron ETF for January 3, 2021 - Novenber 11, 2022 and Sentana and Wadhwani (1992) model was used. Empirical analysis suggests that volatility of fund return is symmetrical against the news. Despite a formal market with full overlapping for the underlying assets, Saffron ETFs investors do not notice about the difference between ETFs' market prices and their Net Asset Value (NAV). The results of the feedback trading model show that there is no evidence of feedback trading in Saffron ETF. It seems that the market of Saffron ETF is efficient, which can be related to the specificity of the underlying assets and the investors of these ETFs.

Environment quality and its determinants are one of the main challenges of the present and future of humanity and sustainable development is interpreted in the direction of preserving and improving the environment. In recent years, many studies have been conducted on the factors affecting environmental quality. One of the main topics that have been less considered in the related studies is the impact of governance on the quality of the environment. In this study, the impact of good governance components, including economic freedom, trade freedom, and political freedom, on the Environmental Performance Index (EPI) and its sub-indices including environmental health, ecosystem vitality, and climate change is investigated. The data required for statistical analysis are related to Middle East and North Africa region countries and Turkiye (MENAT) during 2000-2021. The panel data method was used to estimate the model and examine the relationship between the variables. The findings show that there is a positive and significant relationship between economic freedom and political freedom with the environmental performance index (EPI), and there is no significant relationship between trade freedom and EPI. </span>In addition, the study found that economic freedom had a detrimental effect on ecosystem vitality and climate change, leading to negative impacts in these areas. However, it had a positive impact on environmental health, indicating that it contributed positively to this aspect. On the other hand, political freedom was observed to have a positive effect on the vitality of the ecosystem and climate change. However, it did not have a significant impact on the overall health of the environment, suggesting that its influence was more prominent in specific areas related to ecosystem vitality and climate change. <span style="layout-grid-mode: line;" data-mce-fragment="1">The result of this research showed that economic freedom has led to more investment in the oil and gas sector of MENA countries, and therefore wastewater and gas emissions have had a negative impact on the vitality of the environment and climate change, but with the increase in production and sales of oil and Gas, per capita income of countries has increased, and environmental health has improved. Also, considering that political freedom among the MENA region has a lot of diversity, the results showed that the countries with more political freedom, through greater awareness of the society and more accountability of the governments and the establishment of environmental protection laws, had a positive impact on the environment. Of course, the environmental health index is more influenced by the economic situation and per capita production of countries and political freedom has little effect on it.
