Migrants,inequalities and social research in the 1920s: The story of Two Portuguese Communities in New England

In this article, I analyse the production and reception of a 1923 social monograph on migrant communities in New England and in doing so: (1) outline an archaeology of the social sciences in the U.S., by analysing aspects of their development, dynamics, institutional politics and research agendas; (2) discuss the tensions between social, racial and cultural interpretations of inequalities in the political economy of the 1920s; (3) analyse the pervasiveness of racialist thinking in science, society and politics, its impact in the hierarchization of groups for purposes of border control, and how the targeted groups responded to it.     

Petrochemical Identification and Insights on Chronological Employment of the Volcanic Aggregates Used in Ancient Roman Mortars

Through the assistance of trace element and petrographic analyses on 14 samples of mortar aggregates from Roman monuments, including the Porticus Aemilia, the Temple of Concordia, the Temple of the Dioscuri, Temple B and other structures of the Area Sacra di Largo Argentina, and the Villa di Livia, we establish the source area and we investigate the chronological employment of the volcanic materials used in ancient Rome's masonry. In contrast to previous inferences, the petrochemical data presented here show that systematic exploitation of the local ‘Pozzolane Rosse’ pyroclastic deposit has occurred since the early development of concrete masonry, at the beginning of the second century bc , through the early Imperial age. Subsequently, exploitation was extended to the overlying Pozzolane Nere and Pozzolanelle deposits. Only during the early phase of development of the concrete masonry in Rome, volcaniclastic sediments outcropping near the construction sites were mixed with the sieved remains of the tuff employed as the coarse aggregate, to produce the fine aggregate. The results of the study on the investigated monuments suggest the possibility of establishing the chronological identification of three different types of mortars, as a function of the composition of the volcanic material employed in the fine aggregate, which, when implemented by future studies, may contribute to the dating of monuments and archaeological structures.     

泉州湾宋代海船保存现状的调查研究

作为国内乃至亚洲大型海洋出水木质文物保护的先例,泉州湾宋代海船自出土至今已保存近40年,经过多年来综合性地保护修复,其保存现状值得关注。本文通过对古船保存环境、船体构件保存状况、船体病害、材质状况的调查分析,综合评估船体保存现状,分析影响古船稳定保存的主要因素,从而为后续的保护工作奠定基础。     

石窟造像防风化加固材料探讨

石窟造像文物具有不可再生性,因此对其保护加固材料的要求非常苛刻,除需具有很好的粘连性、渗透性、透气性、耐候性、疏水性和化学稳定性外,还需具有一定再处理性,且对石窟造像本身无副作用.本文通过对石质文物防风化加固保护材料的梳理,分析了各类保护材料的优缺点和适用性,为我国石窟造像防风化加固保护设计、施工材料选择和应用提供基础资料.     

1951:唯物史观派主流地位的确立

1951年,唯物史观派对于学术机构领导权和学术期刊经营权的掌握和控制以及自身社会地位的提升,使他们成为在学术界确立新意识形态的主导地位、推动学术变革和话语转换的中坚力量;唯物史观派聚拢传统学人进行史料整理、古籍校订,为学术史留下一笔财富。1951年前后唯物史观派主流地位的确立和当时学术格局的变动直接影响了20世纪后半期学术界的走向。     

Multiregional Perspectives on the Archaeology of the Andes During the Late Intermediate Period (c. A.D. 1000–1400)

During the Late Intermediate period (LIP, c. A.D. 1000–1400), the central Andes experienced the decline of the Wari and Tiwanaku states, as well as processes of state formation, regional population growth, and competition culminating in the imperial expansion of the Chimú and Inka polities. The LIP holds the potential to link the archaeological features of early Andean states with the material signatures of the later ones, providing a critical means of contextualizing the intergenerational continuities and breaks in state structures and imperial strategies. The recent proliferation of LIP research and the completion of a number of regional studies permit the overview of six LIP regions and the comparison of highland and lowland patterns of political and economic organization, social complexity, and group identity.     

Effects of distance from stone source on landscape-scale variation in Oldowan artifact assemblages in the Paleo-Olduvai Basin,Tanzania

Ongoing excavations at Olduvai Gorge, Tanzania, reveal tremendous variability among stone artifact assemblages across the Plio-Pleistocene Olduvai Lake Basin during Bed I and lower Bed II times. Theoretically, stone artifact traces of Oldowan hominin land use are determined by the distribution of larger mammal carcasses and arboreal refuge from predation as well as proximity to stone material sources.     

How the Olmec used bitumen in ancient Mesoamerica

Bitumen, found in abundance in Mesoamerica’s southern Gulf Coast region in natural seeps and in many archeological contexts, is an important economic resource and exchange item that has received little consideration in Mesoamerica. Analyses of archeological, ethnoarcheological, and experimental data provide insights on the organization of bitumen processing activities, and the end product (archeological bitumen), which the Olmec (1200–400 BC) used in the production of many items. Archeological data are derived from investigations at El Remolino and Paso los Ortices— two Early Formative period levee sites in the San Lorenzo Olmec region. Our findings suggest that among the Olmec, bitumen processing was organized as a specialized activity, involving multiple production stages, but not necessarily elite involvement or control.
