Hegemonic constraints: The implications of 11 September for American power

At the heart of the post-11 September world lie several critical issues surrounding US power: its unprecedented primacy, the way in which it is exercised, and how it is perceived and received around the world. Even as US primacy and 'hard' power projection have been reinforced, the terrorist attacks and Washington's responses have adversely affected the vital 'soft' foundations of its power: the appeal of American values and culture; the perception that US hegemony is benign; and the apparent legitimacy of the exercise of American power. These trends will, in the longer term, constrain US hegemonic power by limiting the effectiveness of foreign and security policies. At the international level, Washington will experience increased friction and costs in dealing with its allies and other friendly states; and at the domestic level, the Bush and subsequent administrations will have to take into account rising domestic costs of 'blowback'.     

Life history of a mule (c. 160 AD) from the Roman fort Biriciana/Weißenburg (Upper Bavaria) as revealed by serial stable isotope analysis of dental tissues

The presence of the osseous remains of at least four mules in a garbage dump at the Roman fort of Biriciana near the town of Weißenburg, Upper Bavaria, dating to c. 160 AD, raised the question as to whether mule breeding was already performed to the north of the Alps during the Middle Roman Empire, or whether these animals still had to be imported from the Mediterranean. Serial analyses of the dental enamel and dentine of a lower fourth premolar and the surrounding alveolar bone of a mandible of a mule in terms of stable strontium isotopic ratios of the apatite, and stable carbon and oxygen isotope ratios of the structural carbonate, were carried out to test whether this individual moved long distances during its lifetime. Since isotopic ratios obtained by serial analysis can be correlated with consecutive ontogenetic stages, it can be assumed that this particular individual experienced significant changes in terms of diet and environmental parameters after its eighth year of life. These changes included a period of residence in a region of high altitude, most likely the Alps considering the location of the Roman fort where the mule was found. The isotopic data obtained do not contradict the assumption that this animal was bred and raised in northern Italy, to frequent later in its adult life the Alps and finally perish at Biriciana/Weißenburg.

Mapping the desert: Arthur Rimbaud,Charles de Foucauld,and the Société de Géographie, 1884–85

This article focuses on two disparate figures in the French colonial period in Africa, the ex-poet Arthur Rimbaud and the ex-soldier Charles de Foucauld. Between 1883 and 1884, each lived in Africa in self-imposed exile of a sort, and undertook rigorous exploration of the region to which he had relocated himself. Both composed reports on their regions of the ‘dark continent,’ and both reports were submitted to, and recognized by, the Société de Géographie back in Paris. The two geographical texts – Rimbaud's Rapport sur l'Ogadine and de Foucauld's Reconnaissance au Maroc – are watersheds of life-writing, as much as they are representations of colonial Africa observed by Frenchmen. Through comparing the two desert narratives, and considering the two authors' African lives, I argue that the process of writing about the desert actually evokes the essential character of each writer's voice, a voice to which he only found access in the desert. Finally, these voices in turn provide valuable information about the relationship between France and Africa, colonial force and colony, and about the various forms of resistance to each of those roles.     

Understanding the variability in freshwater radiocarbon reservoir offsets: a cautionary tale

Freshwater resources in past diets can lead to inaccuracies when attempts are made to ascertain their radiocarbon ages or those of the consumers. Radiocarbon reservoir effects may lead to significant age offsets when the bones or other tissues of these consumers are radiocarbon dated. A number of recent studies have investigated freshwater reservoir offsets. However no study thus far has satisfactorily obtained a ubiquitous freshwater reservoir correction due to variability in the ecosystems analysed. This study tests the possibility of predicting freshwater reservoir effects from the carbonate alkalinity of the water with measurements on modern fish bone and water samples. A predictive capability would be especially valuable in the absence of well-preserved archaeological fish bone. We surveyed samples from lakes and rivers in varying geological settings in Britain and Ireland. Modern fish bone and water samples were analysed to investigate modern radiocarbon offsets from the atmosphere. Archaeological fish bone was also analysed to examine past reservoir offsets at selected sites. Stable carbon and nitrogen isotope values were measured to aid in interpretation of any variability in the offsets. Large freshwater reservoir offsets were measured in some modern and archaeological samples (maximum offset = 1638 ¹⁴C years). The freshwater reservoir offsets in the fish bone were highly correlated with alkalinity of water in modern lake sites analysed. However, a high amount of variation within and between fish species was also evident in the results, precluding the possibility of providing regional corrections for freshwater reservoir offsets from alkalinity although this still may provide a general guideline. The variability is thought to be due to differences in the diet of individual fish.
