This article surveys and discusses prominent protagonists of the debate on socio-economic inequality in the Arab region, with a special focus on the World Bank and Egypt. According to official data, the region holds remarkably low Gini coefficients in a context of declining inequality. This contradicts the popular perception of high social inequality as a major cause of regional protests since the Arab Spring; hence the reference to a ‘puzzle’ in mainstream literature. The debate about the reality of social inequality in the region has developed since 2011 — particularly in regard to Egypt, where income and consumption data are periodically collected by means of household surveys. Inequality measures based on this method alone, while income taxation data are inaccessible, are highly questionable and conflict with various observations and calculations based on other indicators such as national accounts, executive income or house prices. Yet, the World Bank upholds official inequality findings in portraying the Arab upheaval as the revolt of a ‘middle class’ that aspires to greater business freedom, in consonance with the neoliberal worldview.  相似文献

The rate at which endogenous DNA from differently prepared (butchered, boiled and baked) compact pig bones degrades in five different Danish terrestrial and marine environments over 12 months was investigated. Although > 70% of the estimated endogenous mtDNA is lost after just four weeks of exposure, no cytosine deamination of DNA was recognised. A correlation between the presence of oxygen and the amount of preserved DNA was observed. The results provide valuable information on the interaction between the endogenous DNA and the depositional environment in the early stages of bone diagenesis, which can be a support in the interpretation of the initial diagenetic pathways of archaeological bone.  相似文献

This roundtable assesses the arguments and importance of Guido Formigoni’s book Storia dell’Italia nella Guerra Fredda (19431978). This book is essentially composed of seven 70–80-page broadly chronological chapters, each of which might almost be expanded into a short book in its own right. The chapters perform the difficult feat of shifting constantly between the foreign policy of the Italian state (which was so often driven by domestic political considerations) and the political consequences of international events on the debates (or polemics) taking place in the Italian polity. There can be few works of international history in which the linkage between the domestic and foreign policy ‘levels’ is so clearly demonstrated. Indeed, one of the key objectives of the book plainly is to show that although there may be countries where foreign policy is carried on with blithe indifference to domestic politics, Italy is certainly not one of them, or was not during the Cold War years. Mark Gilbert introduces the book on which Federico Romero, Maud Bracke and Michele Marchi engage in a detailed commentary, to which the author replies.  相似文献
