This paper reports on the construction of a full‐scale Bronze Age‐type sewn‐plank boat based on the Ferriby boats. The boat, which was named Morgawr, was constructed in the National Maritime Museum Cornwall in Falmouth, England, during 2012 and the first months of 2013, as part of a larger exhibition in the museum. This paper provides the background and context of the project, describes the process of building the craft, and reflects in particular on differences between Morgawr and the ‘hypothetical reconstruction of a complete sewn‐plank boat’ published in 1990 by Ted Wright and John Coates which formed the basis for this project.  相似文献

Two stone flakes partly covered in birch-bark-tar and a third without tar on it were discovered in fluvial gravel and clay in central Italy, in association with the bones of a young adult female Elephas (Palaeoloxondon) antiquus and several micromammals. The probable chronology of the stone flakes is compatible with the late Middle Pleistocene suggested by the site's small mammals and geological context. The fauna indicates a cool stadial episode before isotope stage 6. That age means the flakes are the oldest ever found hafted with tar and indicate a greater capacity for late Middle Pleistocene hominins to utilize raw materials available during cold phases.  相似文献

The emergence of capitalism in the peninsula of Yucatán is generally presented as a process resulting from the capitalization of the agricultural sector and the export of products from its sugar, cotton, and henequén plantations in the nineteenth century. In addition to these products, the peninsula also had a dynamic coastal economy in which the harvesting of salt and the extraction of logwood (Haematoxylum campechianum), played a major role and contributed to the flow of goods to international markets. We present a preliminary archaeological survey and historical documentation of El Real de Salinas, a salt-producing port on the north coast of Campeche, which was also involved in the extraction of other coastal products and closely linked to the inland plantation system.

The "congressional dominance" literature in political science provides valuable insights into the legislative control of administrative agencies. However, this literature tends to be conceptualized with respect to regulatory agencies, and it is not especially helpful in understanding the dynamics of policymaking in the provision of human services. After distinguishing the tasks of regulation and human services provision, we present an alternative: a common agency model of human service policy as the outcome of interest group bargaining. We illustrate its implications with an analytic narrative of service provision for the seriously mentally ill.  相似文献
