Only a massive replacement of fossil fuels and wood coal by solar power parks, can wind power and atomic power save mankind from the grave threats of global warming. This paper presents a tentative estimation of what is involved with regard to the fulfilment of COP21 ＇s GOAL II--decarbonisation to 30-40 per cent of 2005 level of emissions.展开更多

Martial law discriminated against Israel＇s Arab minority, as opposed to the majority of Israel＇s society, as part of different issues bound up with this population＇s daily functioning. The aim of the paper is to present the reasons why Eshkol＇s doing away with the martial law stemmed was its ineffectiveness, while the other, and this makes up the core of our concern here, was his changing attitude toward the Arab minority in Israel, by contrast with that of his predecessor, David Ben Gurion The main conclusion of the paper is that even though Eshkol＇s ideas about the Arab minority were not very different from Ben Gurion＇s ideas one insisted on maintaining the military government in Israel, while the other saw this as unnecessary, and so brought it to an end. In August 1963, a few months after assuming office, Israel＇s Prime Minister Levi Eshkol initiated the first steps leading to the annulment of military rulet which had applied to Arabs in the State of Israel ever since the end of the War of Independence （1948）. This process was concluded some three years later. Military rule was lifted in effect on December 1, 1966. In the presentation, the author would like to look into the considerations which prompted Eshkol to take such a step, in light of the fact that his predecessor, Ben Gurion, was a staunch opponent of annulling the military regime, convinced as he was, even after the conclusion of his term in office, that the current state of affairs should remain in effect.展开更多
