The use of discriminant function analyses (DFA) in archaeological and related research is on the increase, however many of the assumptions of this method receive a mixed treatment in the literature. Statisticians frequently use complex statistical models to investigate analytical parameters, but such idealised datasets may be hard to relate to “real-life” examples and the literature difficult to assess. Using two faunal datasets that are more typical of archaeological and related research, one comprised of size-corrected linear measurements of bovid humeri and another of 3D geometric morphometric (GMM) shape data of African monkey skulls, and two simulated datasets, we illustrate some of the most important but often ignored issues of DFA. We specifically show why it is paramount to address “over-fitting” by cross-validation when applying this method and how the probability of correctly classifying cases by chance can be properly and explicitly taken into account. 相似文献

There has been a gradual shift in historical archaeology towards interpretive approaches to material culture, including recognition of the potential for multiple functions and meanings in local contexts. It is argued here that artifacts can also maintain multiple, fluid origins and identities that affect our understanding of the nature of cultural persistence and change among migrant, indigenous and other ethnic groups. However, predefined classification schemes are often rigid and do not allow for this kind of fluidity, including the potential for artifacts from one culture to be indigenized into another. Data drawn from recent research on Japanese migrants in British Columbia, in conjunction with an approach rooted in transnationalism and diaspora, are used to highlight the nature of these ambiguities and to suggest methodological and theoretical means of overcoming them. These solutions include the need to develop contextual classification schemes that incorporate multiple artifact identities and to conduct detailed material culture histories that trace shifting origins and identities both before and during periods of migration or displacement. 相似文献

Regular population censuses are an integral part of the oversight functions of the modern state. Whereas the United Kingdom instituted a decennial enumeration in 1801, it was not extended to the overseas Empire. The administration of the British Empire was decentralised and early nineteenth-century census taking was subject to local initiatives. However, from the 1840s successive Colonial Secretaries considered a unified imperial census necessary to fulfil their oversight functions and demanded the taking of censuses by colonial governments to coincide with that in the United Kingdom. Initial responses were mixed, but with each decade the coverage improved, although no agreement was reached on the questions posed and the classification systems employed. These remained severe drawbacks to the creation of a comprehensive imperial view. Only in 1906 was an official volume entitled Report on the Census of the British Empire published. The experience gained in its preparation, collating the diverse colonial reports prompted the undertaking of a fully coordinated enumeration in 1911. The First World War intervened and prevented publication. Although subsequent attempts were made to revive the concept, little was achieved. The combination of the pursuit of local interests, accentuated by greater political independence, and the lack of adequate resources at the General Register Office in London to coordinate and analyse the results ensured that the quest for a unified census was finally abandoned with the onset of the Second World War. 相似文献

There have been a number of important efforts to map out the languages of Iran, but until now no language atlas, or even a comprehensive and detailed country-level language map, has been produced. One of the recent initiatives which aims to fill this gap is the online Atlas of the Languages of Iran (ALI) (http://iranatlas.net). This article delineates objectives of the ALI research programme, atlas architecture, research methodology, and preliminary results that have been generated. Specific topics of interest are the structure and content of the linguistic data questionnaire; the handling of contrasting perspectives about the status of “languages” and “dialects” through a flexible multi-dimensional classification web; and the role of ongoing comparisons between language distribution assessments and hard linguistic data. 相似文献
