Obsidian sources in highland Yemen and their relevance to archaeological research in the Red Sea region

The Red Sea and surrounding area formed through dynamic uplift and rifting of Afro-Arabia, and associated volcanism (both oceanic and continental in character). As a result, volcanic landforms and products are widespread and play a vital role in the natural and cultural landscapes of humans occupying the highlands and lowlands on both sides of the Red Sea. Archaeologists have suggested for some time that Afro-Arabian trade in obsidian had its roots in the prehistoric period and that the region was very likely the source of an abundance of obsidian artefacts found as far afield as Egypt, the Persian Gulf and Mesopotamia, and which do not match the well-known Anatolian, Transcaucasian or Mediterranean sources. Nonetheless, the southern Red Sea is one of the few obsidian-rich regions exploited in antiquity that has been barely investigated. In this paper, we highlight new geochemical analyses (carried out by LA-ICP-MS) of obsidian sources in Southern Arabia and beyond, that enhance our knowledge of obsidian exploitation from as early as the Neolithic period, and which enable us to evaluate the role that highland Yemen obsidian sources played in prehistoric long-distance trade. In addition, we present new evidence for explosive volcanic eruptions that likely affected the highland populations of Yemen in the 4th millennium BC.     

Potemkin Portals or the Real Revolution? The State of E‐Government in Egypt

Effective and optimized e‐government in Egypt faces daunting challenges that are less technical in nature and more over the issues of institutional resistance and of political will. A review of the state of e‐government in Egypt is presented with analysis focusing on the state of service implementation in 2012. The points of discussion on e‐government covered here include:

• E‐subjugation in the guise of e‐government via information control and cyber‐snooping;
• Institutional resistance to the transformation of routine functions into automated systems;
• Institutional resistance to transparency of government operations;
• Analysis of the state of Egyptian ministry websites on six dimensions of e‐government development;
• Discussion on implementation of Egypt's e‐government master plan;
• Commentary on the revolutionary potential of e‐government augmented by vision, competence, and leadership; and
• Caveats that are important to note in moving the vision of e‐governance from concept to practice.

     

Incentives for the Iranian Chemical Boom: A Strategic Motivation or Applied Needs?

Iran's scientific impact has suffered hard from decades of imposed and self‐elected isolation from Western influences and international collaboration. Lately, however, the world has witnessed a remarkable increase in scientific publications from Iranian scientists in fields like nanotechnology; material science; and, perhaps most pronounced, chemistry. In this article, the factors behind this “publication boom” are discussed and examined together with an analysis of the coherence between the country's long‐term research strategies and short‐term needs in relation to present organic chemical research conducted at various Iranian universities and institutes. Organic chemistry is a keystone in important Iranian industrial sectors like the petroleum and agricultural industries, and also in the growing field of life science and pharmacology. The development of the petroleum industry and further refinement of raw oil into value‐added fine chemicals holds a key position in the reinforcement of the Iranian economy and labor market, thus motivating a governmental investment in chemical science and research. Taking an approach to find a reasonable balance with the impact from Western and Far Eastern scientific communities, Iran's own scientific roots and Islamic ideology could well be the success factor in becoming a worthy player on the international scientific arena.
