从表面上看,《贩书偶记》只是书商出身的文献家孙殿起先生在经营古书时编录的一部图书目录,但它在著录图书之时,对与各图书相关的重要信息或多或少地作了一些抄录,这些信息包括撰者的生平传记、著述情况、书籍本身的刊刻、序跋等等,尽管零零总总,却有着十分重要的史料价值。  相似文献

文化遗产调查的内容和应当追问的问题对于遗产管理具有重要的意义,如对于文化遗产本身的景观分布范围、社会原生背景、使用和改用状况以及对于反映人地关系和遗产压力等方面因素进行的分析,都是对遗产进行评估和处理的依据来源,这些调查内容都应被视为对遗址进行管理的基本参数来源,也是对遗址进行规划的基础。我国目前的遗产实践中尚存在遗产调查上的缺陷,主要表现为遗产调查简单化和离散化,对于遗产调查的细化和整合是亟需解决的方法论问题,特别是对于遗产范围的认定、遗产与现代社会的关系以及遗产本身的背景和现实处境都缺乏具有针对性的调查手段。这些问题成为遗产保护和利用的较大的障碍,而解决的途径应当是改进遗产调查模式。  相似文献

Temporally and spatially discontinuous pulses of heavy prehistoric exploitation of red abalone (Haliotis rufescens) have been documented along the southern and central California coast. This article examines the very late (post-950 cal BP) appearance of numerous red abalone processing sites on the Monterey Peninsula in central California. We test three prominent explanations offered for the sudden onset of red abalone processing sites: trophic cascades resulting from human predation on sea otters, logistical foraging by inland residents, and changes in sea surface temperature. A trophic cascade appears to have occurred but does not fully explain the nature or timing of the phenomenon in the region.  相似文献

The following article corrects the mistaken assumption held by a number of historians that during the reign of Charles VI of France it was necessary for the Parlement de Paris to publish and register all important royal ordinances before they could be executed. Individual cases are discussed to show the nature of the prerogatives of the Parlement and the methods used for the ratification and registration of royal acts.  相似文献

The early medieval period marks an important turning point in the history of glassmaking, since it comprises the transition period between the mineral-based silica-soda-lime glass of the Roman tradition and the plant ash-based glass. With the aim of expanding the knowledge on the glass recipes and technologies of this period, 37 glass samples were analyzed, originating from the archaeological excavations of San Genesio (Tuscany) and dated from the fourth to the eleventh century. The major and minor element concentrations were measured with SEM-EDX, while the trace elements were quantified with LA-ICP-MS. The results were compared with published compositions of glass samples of similar age in order to highlight differences and similarities. The results offer a very interesting view on the glass circulation in the religious/residential/manufacturing center of San Genesio in the early medieval period. Most of the glass has a typical late-Roman composition, but some glass fragments are identified as soda ash glass. These are among the earliest medieval ash-fluxed glasses ever found in the Italian peninsula.  相似文献

Flemish 15–17th century tapestries are among the most precious testimonies of European cultural heritage. Even in their deteriorated condition, they are still highly valued and exhibited in many museums all over the world. The present state of degradation evidenced by visual assessment in conservation practice, and confirmed with macro-scaled tensile strength tests, reveals the vulnerability of the wool and silk fibres to light exposure.  相似文献

Stable carbon (δ13C) and nitrogen (δ15N) isotope analyses of dog (Canis familiaris), island fox (Urocyon littoralis), and human bone collagen from CA-SRI-2 (AD 130–1830) on Santa Rosa Island, California provide a proxy of diet and the relationships between humans and these animals. Carbon isotopic signatures indicate that Native Americans and their dogs at CA-SRI-2 subsisted almost exclusively on marine resources, while the island fox ate primarily terrestrial foods. Nitrogen isotopes and archaeofaunal remains indicate that humans and dogs also ate higher trophic level foods, including finfishes, marine mammals, and seabirds with smaller amounts of shellfish. The CA-SRI-2 island foxes appear to have eaten higher amounts of terrestrial foods, similar to the diets observed in modern fox populations. These data generally confirm the commensal relationship assumed to exist between domesticated dogs and people, but the carbon isotopic composition of dogs is enriched ∼2‰ compared to humans. We hypothesize that the difference in carbon isotopes between dogs and humans may have resulted from a higher consumption of C3 plants with lower δ13C values by humans, or less likely from the ingestion by dogs of significant amounts of bone collagen, which is enriched by ∼4‰ over associated muscle.  相似文献

1932年中国历史上第一部铁路基本法——《铁道法》正式颁布。《铁道法》的诞生,既迎合了近代国人对铁路国有化的产业发展路径,也符合了铁路法制由简至繁、由缺至全的演进路径。《铁道法》是国民政府推行铁路产业政策的根本性立法,但在实施过程中受到了阻力,在不断的外耗与内耗中效力有限。  相似文献
