In the years following World War One the pastoral populations of northern Arabia were subjected to political pressures and economic hardships arising from the creation of French and British spheres of influence in the territories that would become the states of Jordan, Syria and Iraq, and by the aggressive expansion of the domains of the ruler of Najd, ‘Abd al-‘Aziz ibn ‘Abd al-Rahman Al Saud. Year by year the nascent states in the region asserted more control over the vast stretches of desert and steppe that had heretofore been the domains of powerful bedouin tribes and confederations. New borders often cut across tribal territories creating complications and conflict in such matters as sovereignty, citizenship, migration, raiding and political refuge. The establishment of new customs regimes and economic policies meant that age-old patterns of trade between the settled and nomadic populations were altered, curtailed or criminalized as ‘smuggling’.
This article examines two sets of policies that Iraqi and Saudi forces employed to express political domination in the desert and steppes of Kuwait and beyond in the guise of controlling trade: the Saudi blockade of overland trade with Kuwait; and Iraq's aggressive ‘anti-smuggling’ measures that often victimized innocent bedouin. In both cases, members of bedouin tribes were harassed, attacked, pillaged and forced to alter their normal patterns of trade and migration. The eventual rise and dominance of state power resulted in the historic defeat of bedouin control in the deserts and steppes and a gradual loss of their traditional economic options. This article provides detailed evidence showing how part of this large transformation in bedouin society took place. 相似文献
The complex nature of medieval Arabic compilations, with their evidence of manifold pieces and layers of diverse (older) text material, has been puzzling to many scholars of Islam. It has even caused some researchers to question the authenticity and credibility of information contained in these texts—and their value as historical sources—altogether.
An inquiry into the theoretical controversies at issue here constitutes the starting point of this article. Additionally, we will look at the categories and terms more frequently used in Western studies of the sources of Arabic compilations from about the eighth to the eleventh century Common Era (CE). The second part of the article offers an extensively annotated catalogue of categories and terms. This terminology, it is hoped, will help advance the assessment of classical Arabic compilations, for it takes the actual circumstances of the transmission of knowledge and the working techniques of compilers in medieval Islam into proper consideration. In conclusion, the paper illustrates how the proposed categories and terms are to be applied. It will become clear that the application of this kind of refined source-critical examination of individual classical Arabic texts is instrumental to a better understanding of medieval Muslim scholarship in general. 相似文献
Research has shown that the prevalence of deliberate self-harm (DSH) is higher in adolescents than in adults, but little is known about other differences. In this study we compare adolescent and adult DSH-patients regarding factors contributing to the suicidal act. In two regions in Norway, 98 persons under 20 years of age and 83 older persons were interviewed following an act of DSH. They were compared regarding intentions involved in the DSH, precipitating circumstances, level of suicidal intent, medical seriousness of the act, depression, hopelessness, and self-esteem. Few differences were found. The adults more often wanted to escape from unbearable thoughts or situations, or to receive care and attention. Adults also reported a slightly higher level of medical seriousness of the DSH act, more psychiatric problems, and substance abuse. The similarities between young and adult DSH-patients are striking. The differences found are most likely related to factors of age itself, such as cognitive immaturity, impulsivity, and lack of experience in enduring problems. 相似文献
A 1H nuclear magnetic resonance (1H NMR) method for the determination of gamma-hydroxybutyric acid (GHB) and gamma-hydroxybutyrolactone (GBL) in human serum and urine using spiked samples has been developed. The method gives linear responses (correlation coefficients of 0.99 or greater) over the concentration range 0.01 mg/mL to 4.0 mg/mL in urine and 0.3 mg/mL to 2.0 mg/mL in serum. No sample pretreatment is required. Studies of the chemical interconversion of GBL and GHB showed hydrolysis of GBL to be rapid at pH 11.54, slower and less complete (30% hydrolysis) at pH 2.54 and slowest at pH 7.0, reaching 30% hydrolysis in about 40 days. No esterification of GHB was observed at any pH. 相似文献
In a second test of an arthropod saturation hypothesis, we analyzed if the on-campus Anthropology Research Facility (ARF) at the University of Tennessee, Knoxville, with its 20+ yr history of carcass enrichment, is comparable to non-enriched sites in community structure of predatory and parasitic arthropods that prey upon the sarcosaprophagous fauna. Over a 12-day period in June 1998, using pitfall traps and sweep nets, 10,065 predaceous, parasitic, and hematophagous (blood-feeding) arthropods were collected from freshly euthanized pigs (Sus scrofa L.) placed at ARF and at three surrounding sites various distances away (S2-S4). The community structure of these organisms was comparable in most paired-site tests with respect to species composition, colonization rates, and evenness of pitfall-trap abundances on a per carcass basis. Site differences were found in rarefaction tests of both sweep-net and pitfall-trap taxa and in tests of taxonomic evenness and ranked abundances of sweep-net samples. Despite these differences, no evidence was found that the predatory/parasitic fauna at ARF was impoverished with fewer but larger populations as a result of carcass enrichment. Comparison of the sarcosaprophagous and predatory/parasitic faunas revealed a tighter (and more predictable) linkage between carrion feeders (sarcosaprovores) and their carrion than between carrion feeders and their natural enemies (predators and parasitoids), leading us to conclude that ARF is more representative of surrounding sites with respect to the sarcosaprovore component than to the predatory/parasitic component within the larger carrion-arthropod community. 相似文献
