Michael Schiffer’s Behavioral Archaeology is one of several moves in mid- to late twentieth century archaeology toward actualistically based, detailed materials analysis with the aim of developing uniformitarian principles to apply to archaeological cases. Substantial parallels exists between Schiffer’s agenda and its products and those of at least some zooarchaeologists and taphonomists, including use of chaîne opératoire or behavioral chain approaches and experimentation, as well as other materials analysis agendas. Differences as well as similarities are explored, as are continued impediments to development of archaeology as a systematic science.  相似文献

Einkorn (Triticum monococcum L.) was one of the first cereals to be domesticated in the Old World ca. 10,000 years ago and to spread towards Europe and North Africa. Its cultivation declined before the Iron Age and it remains today only as a relic crop in remote areas. To investigate if the geographic distribution of genetic diversity in modern einkorn landrace accessions could be informative about the movement of this crop during prehistory, we genotyped 50 accessions of einkorn from Europe, North Africa and the Near East. Using nuclear and chloroplast microsatellites and clustering methods, we detected two main gene pools in einkorn. The distribution of these lineages revealed differences between accessions from Morocco and the Iberian Peninsula from the rest of Europe and the Near East and suggests different regional dynamics in the spread of this crop.  相似文献

One can easily use nineteenth-century tithe data of England and Wales in a Geographic Information System (GIS) to analyze a range of subjects, for example, land use, productivity, land ownership, or tenancy. Making the tithe data GIS ready, on the other hand, is a nontrivial matter. The tithe data consist of two main types: spatial, that is, the tithe map, and nonspatial attribute data linked to the map. The tithe therefore has the characteristics of a GIS, albeit in paper form. The author outlines the process of creating the structures for building a data repository that allows the storage and dissemination of both tithe schedules and maps in a single GIS-ready system. The author chose Oracle to host the repository. The Oracle Spatial module allows storage of both spatial and attribute information. Oracle also provides the means of serving data to users via the Internet.  相似文献

Henricus Martellus's four world maps of c.1489 show a non‐existent Asian peninsula east of the Aurea Chersonesus (the Malay peninsula). For some decades a group of scholars in Latin America has been claiming that this so‐called ‘Dragon's Tail’ peninsula is really a pre‐Columbian map of South America. In this paper, the cartographical and place‐name evidence is examined, showing that the identification has not been proved, and that perceived similarities between the river and coastal outlines on this ‘Dragon's Tail’ peninsula and those of South America are fortuitous. Ptolemy's depiction of an enclosed Indian Ocean was invalidated when Bartolomeu Dias rounded the Cape of Good Hope. Consequently, a year or two later, Martellus adapted the east Asian section of Ptolemy's world map, providing China with an east coast and turning the southward extension of Asia into a peninsula. The non‐Ptolemaic place‐names on these maps were derived from Marco Polo's writings.  相似文献

All U.S. states have laws designed to discourage people from drinking and driving, but enforcement varies across the states. Existing studies offer conflicting evidence on the effectiveness of these strategies in deterring drinking‐and‐driving behavior. Deterrence theories imply that the mere existence of such laws has little impact on criminal behavior, but the perception of enforcement and the probability of being detected have a deterrent effect. To test these hypotheses, we develop a measure of the propensity to drink and drive using item response theory and national survey data. Inferential models test the impact of perceptions of enforcement, actual enforcement levels, and deterrence laws on criminal propensity. Results indicate that the existence of statutes impacts only those least likely to drink and drive, while perceptions of the likelihood of arrest and individual agreement with the goals of drinking and driving laws significantly reduce the propensity for almost everyone. Actual enforcement rates display no behavioral effect.  相似文献

Public policy has been a prisoner of the word “state.” Yet, the state is reconfigured by globalization. Through “global public–private partnerships” and “transnational executive networks,” new forms of authority are emerging through global and regional policy processes that coexist alongside nation‐state policy processes. Accordingly, this article asks what is “global public policy”? The first part of the article identifies new public spaces where global policies occur. These spaces are multiple in character and variety and will be collectively referred to as the “global agora.” The second section adapts the conventional policy cycle heuristic by conceptually stretching it to the global and regional levels to reveal the higher degree of pluralization of actors and multiple‐authority structures than is the case at national levels. The third section asks: who is involved in the delivery of global public policy? The focus is on transnational policy communities. The global agora is a public space of policymaking and administration, although it is one where authority is more diffuse, decision making is dispersed and sovereignty muddled. Trapped by methodological nationalism and an intellectual agoraphobia of globalization, public policy scholars have yet to examine fully global policy processes and new managerial modes of transnational public administration.  相似文献
