《晋书·地理志》县级封国考论

反映西晋前期政区全貌的《晋书·地理志》中记载了58个县级封国,包括公国、侯国两类。虽然西晋朝廷已设置公、侯、伯、子、男五等爵,但这些封国所对应的爵位,却是位在五等爵之下的一般县公、县侯。各家县公主要是由曹魏宗王降封而来。为县侯者,有功臣、敌国降将、曹魏宗室,还有不少是曹魏时即已受封而入晋后仍保留爵位者。     

Strontium isotope ratios in fossil teeth from South Africa: assessing laser ablation MC-ICP-MS analysis and the extent of diagenesis

This study tests the precision and accuracy of laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) for measuring strontium isotope ratios (⁸⁷Sr/⁸⁶Sr) in fossil teeth from Swartkrans and Sterkfontein in South Africa, and explores the extent of diagenesis in these specimens. Compared to solution MC-ICP-MS or thermal ionization mass spectrometry (TIMS) methods, LA-MC-ICP-MS can be faster and less expensive, but has lower precision and accuracy. We found that ⁸⁷Sr/⁸⁶Sr ratios in fossil rodent teeth measured by LA-MC-ICP-MS were offset from solution values by a mean of 0.0005 ± 0.0010 (2σ). Because of the very wide spread of biologically available ⁸⁷Sr/⁸⁶Sr ratios (∼0.710 to ∼0.790) in the region, LA-MC-ICP-MS is more than sufficient for assessing the geographic origins of the fossil rodents. The concentration of strontium in modern and fossil enamel from the area is statistically indistinguishable, as is the range of ⁸⁷Sr/⁸⁶Sr ratios in modern rodents and fossil rodents from Swartkrans. Thus, there is little evidence of diagenetic Sr in the fossil enamel. In contrast, the fossil dentine may contain up to ∼50% diagenetic strontium, although many dentine ⁸⁷Sr/⁸⁶Sr ratios are still far removed from the background cave value of 0.729. We propose that LA-MC-ICP-MS will also be of use for investigating the geographic origins of other, non-rodent fossil teeth from the Sterkfontein and Swartkrans collections, and may prove of similar utility at other suitable sites.     

Charcoal reflectance measurements: implications for structural characterization and assessment of diagenetic alteration

Charcoal is a valuable source of archaeological and palaeoenvironmental proxy data. However growing evidence suggests that production conditions can strongly influence post-depositional alteration of charcoal. Consequently, both reconstruction of production temperature and understanding of the potential for diagenetic alteration are of great interest. Here, we use mean random reflectance (Ro_mean) in conjunction with other chemical characterization methods to address these questions. Ro_mean was obtained for a suite of modern analogue charcoal, produced under controlled conditions, and for a series of natural charcoal samples, obtained from archaeological and palaeoenvironmental deposits. Ro_mean proves to be a robust measure to assess formation temperature for samples produced at 400 °C and above, even after exposure to highly oxidizing conditions. Ro_mean is also useful for samples formed between 300 °C and 400 °C. However, if an assemblage of charcoals has been exposed to oxidizing conditions, lower temperature charcoals may be preferentially lost. It is apparent that charcoal produced at lower temperatures is more highly susceptible to chemical oxidation, and that there is a continuum in charcoal degradation potential, dependant upon fuel material and production conditions.     

Chihr de l’encens (Yémen)

Frankincense burners found in al‐Shihr’s excavations in Yemen, a frankincense harbour during the Islamic period, represent a rare corpus of this type, which is an indication of both specific use and goods from South Arabia. Although associated with the pre‐Islamic South Arabian kingdoms, the frankincense burner evolved throughout the Islamic period. This is proved by the long chronological sequence of the al‐Shihr site (780–1996). Texts quoting the presence of frankincense, its use and its trade in al‐Shihr are cited in this article to support the reputation of this harbour‐town, which is part of the maritime trade networks of medieval Islam. The aim of this article is to create a renewal of interest in future archaeological research about this object, which is so often neglected in spite of its importance as a testimony of the customs and exchanges that are deeply rooted in Arabian civilisation.     

The Functional Resilience of an Innovative Cluster in the Montpellier Urban Area (South of France)

The aim of this article is to evaluate the resilience of territories through a study of the morphology of local firms' networks: in this case, in the Montpellier urban area. Two types of data collection were used for the analysis: a statistical survey of a sample of firms and a list of shared patents pending. The first step of the approach enabled us to analyse the motives that led firms to develop innovative partnership. In the second step, we modelled the networks, using graph theory, over different periods of time. Ultimately, the analysis revealed pivotal firms within the network. These firms played an important role in the resilience and spatial organization of the territory. We found that the geographical concentration or dispersal of the firms thus continued under certain economic conditions.     

A new military history of the Italian Risorgimento and Anti-Risorgimento: the case of ‘transnational soldiers’

The article discusses new studies of foreign soldiers in the Italian armed groups of the (Anti-)Risorgimento against the background of recent scholarship on ‘transnational soldiers’, which acknowledges the complexities of foreigners' initial motives for enlistment and of the transnational processes inside the single armies. The article suggests that from the mundane structures of military life to the perceptions of the rank-and-file, many aspects of the soldiering experience in the multinational armed groups on all sides of the Risorgimento actually advanced rather than obviated national boundaries. This paper further demonstrates that the military cultures of the nationalists and the anti-unity forces were much more porous and mutually constitutive than is often recognised. The histories of the ‘transnational soldiers’ in the armed groups of the Risorgimento and Anti-Risorgimento are crucial for a possibly new, comparative history of the armed groups of the (Anti-)Risorigmento. This paper explores approaches of the culturally revived ‘new military history’ and suggests that it provides much still unrealised potential for Risorgimento historiography.     

Medical science and the military: the Allies' use of amphetamine during World War II

Although amphetamine was thoroughly tested by leading scientists for its effects in boosting or maintaining physical and mental performance in fatigued subjects, the results never provided solid grounds for approving the drug's use, and, in any case, came too late to be decisive. The grounds on which amphetamine was actually adopted by both British and American militaries had less to do with the science of fatigue than with the drug's mood-altering effects, as judged by military men. It increased confidence and aggression, and elevated "morale."
