The objective of this study is to understand the shift in the nuclear policy of the Islamic Republic Revolutionary Guards (IRGC). As a military organization considered to be the steward of the nuclear programme, the Revolutionary Guards turned into spoilers on the few occasions when the pragmatists in Iran tried to negotiate a deal with the international community. In a surprising shift, the Guards’ nuclear policy changed and supported nuclear negotiations and the nuclear agreement. It is assumed that the IRGC is more interested in its economic ventures than in promoting the nuclear project. To test the hypothesis, the present study is designed to provide a rigorous empirical examination of the economic impact of the sanctions on the Revolutionary Guards.  相似文献

This paper aims to explore various possibilities in the evolving global gas market by constructing game-theoretical models involving the major players: Russia and Qatar exporting gas to the Asia-Pacific and Europe, respectively. We explore a series of hypothetical scenarios based on competitive and collusive settings for the Asia-Pacific LNG market and based on Qatar’s export route to the European gas market. The scenarios that are examined are (1) Russia as the follower and Qatar as the leader in a Stackelberg game; (2) Russia and Qatar as Cournot competitors; (3) collaboration between Russia and Qatar as bilateral monopolies; (4) Qatar exporting gas to European borders; (5) Qatar exporting gas to the last transit country; and (6) Qatar transporting gas to the Turkish border under a multi-pricing scheme. Demand is estimated under each scenario to simulate the respective export volumes, prices and quantities, and profit in each scenario. By exploring these market interactions, we find that it is essential for Russia to strike a deal with Qatar in the Asian market and accelerate their gas production in order to compete as an LNG market leader. Russia is likely to benefit more if it can link with Qatar to act as a monopoly on their segmental demand curve. On the other hand, Qatar’s profit is expected to be higher under the scenario when Qatar sells all the gas to the last transit country as the sole demand point instead of passing through transit countries.

The 1979 Islamic Revolution in Iran led to a set of major shifts in the Middle East and an anti-Israeli stance became a central approach of the revolutionaries. Up to 1979, however, Tel Aviv had a close relationship with Tehran whose enmity with its Arab neighbours was anchored in a historical struggle for regional supremacy. Israel has remained an enemy of Islam and the Muslims for the revolutionary leaders and as Iran's power grew Israel's anxiety increased accordingly. A new division of power in the region and Iran's pursuit of nuclear weapons led to a direct rivalry between Iran and Israel and consequently many Israelis have come to regard Iran and its nuclear program as an existential threat to Israel that has to be halted. This article explores the roots of enmity between these two countries, scrutinizes the threats of a nuclear armed Iran for Israel and attempts to determine what kind of measures might work to convince Iran to renounce its nuclear program. The article has four sections with the first section covering the history of the relations and the origins of hostility between Iran and Israel. The second section provides a brief overview of how the division of regional power led to direct rivalry between Tehran and Tel Aviv. The third section details Iran's nuclear program and examines its threats to Israel and the last section covers the current sanctions debate over what type of measures might work to compel Iran to renounce its nuclear weapons.  相似文献

This study focuses on the relationship between the incidence of homicide, rage, suicide, and psychiatric hospitalization as violent behaviors with temperature, humidity, and air pressure as specific meteorological variables in the city of Mashhad, in the northeast of Iran. The data were obtained from Iran Meteorological Organization, official registry of Legal Medicine Organization and the local psychiatric hospital, March 2009 to Feb 2010 daily and were analyzed with SPSS‐14 using Pearson correlation coefficient, ANOVA, and post hoc analysis tests. The rates of rage and psychiatric admission had a significant relationship with the daily mean air temperature, minimum relative humidity, maximum relative humidity, minimum daily pressure, and maximum daily air pressure (p < 0.0001). There was no significant correlation between homicide and suicide rates with any meteorological variables (p > 0.05). We concluded that, the possibility of nonfatal violence and psychiatric hospitalization would increase in hot and arid weather with low air pressure.  相似文献
