Amidst the ongoing crisis of plummeting oil prices, the GCC (Gulf Cooperation Council) terrain has become a haunt of economists and financial analysts to tackle the ongoing challenges in the region. GCC constituents are gearing themselves with a robust political will that they hope could result in a turnaround of their economy by adopting a policy of economic diversification in nonoil‐based sectors. With this background supported by extensive qualitative scan of literature pertaining to the reforms proposed by the six members of the GCC to drive the economy forward amidst ongoing economic crisis, this article seeks to underscore the prospect of a shared initiative by the GCC constituents in institutionalizing a GCC bank as a potent innovative solution which may serve to provide an edifice for pushing forth the region's economy in nonhydrocarbon segments contingent upon the individual needs of the GCC constituents. As an exploratory study, this paper sheds light on these issues besides discussing the fundamental functions of the GCC bank.  相似文献

This article seeks to explain revolutionary Iran's convoluted rise to regional prominence over the last three decades. We hold that perceptions and misperceptions of regime stability (both of one's self and of others) by the relevant actors have played a major role in Iran's recent. The main logic is that the success of many strategies employed by relevant regional actors to augment their regional influence (both Iran seeking more influence and others seeking to stem that influence) have crucially hinged on making correct assessments of regime stability. This study has both theoretical and empirical findings. Theoretically, we find that failures to accurately estimate regime stability stem from three main sources: (1) objective uncertainties regarding the target state's level of regime stability, given the high strength of societal forces shaping state‐society relations in the Middle East and given the distinct variation between autocrats in terms of their ability to develop effective counterrevolutionary/repressive tools; (2) ideological blinders, from which both the United States and regional actors frequently suffer, which have often led them to be falsely optimistic regarding the existence of either subversive opportunities or opportunities to stabilize regimes facing domestic pressures; and (3) incorrect theories regarding sources of regime stability which lead experts and policymakers to overlook factors which may destabilize a regime. This article has two major empirical findings. First, Iran's rise may be at least partly attributed to Iran demonstrating a slightly better learning curve at the tactical level (i.e., learning subversive skills from its Lebanese experience in the 1980s–1990s and applying them to Iraq in the 2000s–2010s) as well as at the strategic level (i.e., understanding the limits of its subversive capacities and correctly assessing when it can engage in successful stabilizing operations). Second, two errors committed by the United States have been far more consequential than those committed by Iran for the regional balance of power: First, the George W. Bush Administration myopically opened up subversive opportunities for Iran when it invaded Iraq in 2003 by thinking that it could stabilize a democratic regime and insulate it from outside influence; second, on two occasions Washington overestimated the transformative effect that its concessions to Iran would have in terms of sufficiently empowering reformists so as to bring about complete regime transformation from within.  相似文献

Academia is expected to act as a cognitive arena in which members intellectually challenge one another, problematize social structures, and destabilize dominant ideologies. It is, supposedly, a cognitively unstable environment wherein intellectualism pushes social boundaries and acts as an agent for social change. It is a training camp wherein people come to be trained in the practice of critical thinking. Hence, one would imagine that academia would be the last place to find passive conformism. However, does this image reflect reality? Having interviewed four groups of 50 students, 47 academics, and 28 support staff in three Saudi universities, passive conformism (be it unethical, managerial, or in the form of logistical conformism) appears to be a necessity in Saudi academia. This suggests that, although academia acts as an authority in regard to critical thinking, it may not internalize this philosophy or expose its own organizational activities to such thinking. Passive conformism in Saudi academic organizations is enhanced by wider Saudi culture which promotes conformism among its citizens and directs every aspect of public and private lives, including the lives of its academic organizations. A theoretical proposition could be therefore that passive conformism in a society could be transmitted to its organizations.  相似文献

ABSTRACT

South Africa's northern Namaqualand coastal desert is the southern extension of the Namib. Today, this region is semi-desert with patchy subsistence resources and scarce, unpredictable rainfall. Yet this ancient desert landscape possesses residues of human activity stretching back into the Middle Pleistocene, evidenced by heavily weathered surface finds, including handaxes and Victoria West cores. Such old finds in so harsh an environment raise important questions: how do human movements into this area relate to local palaeoenvironmental changes, and how has this relationship changed through time? While no dated Middle Pleistocene sites presently exist to reconstruct the earliest hominin dispersals, several late Pleistocene sites now have chronostratigraphic sequences that can be brought to bear on these questions. This article presents chronological and subsistence-settlement data for one such site, Spitzkloof A Rockshelter in northern Namaqualand's rugged Richtersveld. Humans are shown to have visited the site very sporadically between ~50,000 and 17,000 cal BP. Unlike most of the subcontinent, the most intensive occupations occur during early Marine Isotope Stage 2, when multiple proxies suggest enhanced humidity associated with intensified winter rainfall. We examine these data using the region's better-developed Holocene archaeological record to create predictions about the earliest coastal desert dwellers.  相似文献

Research on the decomposition of bone collagen offers the key to a wealth of hidden information, for instance, to understanding palaeoclimatic conditions; habitat-specific parameters such as altitude; and for the reconstruction of palaeodiet and subsistence patterns. Radiocarbon dating, one of the most commonly used geochronological techniques is also preferentially carried out on bone collagen. Because negatively charged ions, and especially phosphate groups, are responsible for the tight bonding between organic molecules and bone, soluble serum proteins need not necessarily be leached from buried bone. The authors' hypothesis is that intruding minerals, aided by recrystallization of the bone mineral matrix, and colloid formation, aided by humic substances, form protective layers that preserve serum proteins in bone even after long periods of burial. We have used electrophoresis and Western blotting to recover protein fractions from about 150 archaeological bones from various sites and epochs (up to 5500 BC ) and have succeeded in recovering, purifying all, and identifying some of the proteins. Molecular weight bands corresponding to albumin, transferrin and a-2HS-glycoprotein (A2HS) were frequently recovered. This paper presents the method for separating serum proteins from archaeological bone and for their identification. Twenty-five per cent of samples with the respective molecular weight band still gave a positive immunological reaction with antibodies. We conclude that non-collagenous proteins, especially serum proteins, may be well preserved in bone.  相似文献

Within the context of white marble provenance research, 42 powdered white Greek marbles have been characterized using electron paramagnetic resonance (EPR) spectroscopy. Phase analysis was first carried out to separate calcitic and dolomitic marbles, then EPR spectra of Mnuc were studied. Investigation of other marble EPR spectra, especially around g — 2.00, led us to characterize five different signals. The intensities of Mn2+ lines permit the separatum of eight quarries into two groups, allowing a first discrimination, in the g = 2,00 region, only one signal has been found to be useful for provenance research objectives. The results are cheering and should lead to many other similar experiments.  相似文献
