论文基于《华侨华人历史研究》1982年以来刊发的约60篇马华研究论文,同时参考近年来大陆有关马华研究的博士论文,分析了大陆关于马华研究的主要领域、资料来源、资料类型、研究方法、作者群特点等。研究显示,大陆关于马华的研究,涉及到政治、政策、宗教、文化、社会、文学、女性、族群关系、医学和音乐等领域;研究者重点使用的是英语资料和马来西亚当地的资料,使用最多的是中英文图书,其次是中文期刊和中文报纸;文献分析法是主要研究方法。大陆已有一批比较固定的马华研究者,但人数相对有限,且少有人进行专一的马来西亚华人研究。选择马华作为博士学位论文研究课题的作者成为当今学界研究马华的主要力量。  相似文献

Starch grains from 31 modern samples of millets derived from the seeds of 7 species within the genus Setaria and 2 species within the genus Panicum were analyzed to determine diagnostic morphological characteristics. Ancient starch grains recovered from a sample of broomcorn millet (Panicum miliaceum) excavated from the Cishan site (10.0-7.6 cal yr BP) in the North China Plain were then subjected to the same analyses to determine the differences in morphologies, if any, between modern and ancient samples. The data indicate that morphological features, and particularly surface and fissure features, will allow for solid identifications of ancient millet starches, while size classes will be helpful, but will not be dependable taxonomic indicators.  相似文献

Ceramic seriation is one of the primary tools used by archaeologists to create chronologies, especially for surface survey data. In this article, we outline a bootstrapped approach to correspondence analysis-based seriation designed to help assess and improve the stability of relative orderings produced through such analyses. This procedure systematically identifies and removes small samples and sites with unusual samples, such as those with multiple components, which are not handled well by seriation and require secondary interpretation. Our approach combines data from multiple projects in the Zuni region of the American Southwest in order to gauge the effects of intraregional variation in ceramic distributions and reexamine prior interpretations of demographic change based on individual projects. This analysis highlights two previously unknown regional trends, including variation in the distribution of multicomponent sites and potential short-term depopulation of a significant part of the region. Based on this example, we further suggest that our method may be particularly useful in situations where little prior chronological information is available.  相似文献

Artefacts made of wood coming from archaeological excavations provide insights into human cultural behaviour of the past. They show how man utilised natural resources and how the development of woodworking techniques and artistic endeavour were developed. Within archaeological contexts, waterlogged anaerobic conditions generally preserve the appearance of artefacts, although wood is subject to severe decay processes. The said conditions can transform the original material into a new one, thus demonstrating specific differences from those of the “fresh” wood of the same species. In order to assess these new properties correctly, an integrated diagnostic approach is needed, one which includes a multidisciplinary (micromorphological, physical and chemical) evaluation of the state of preservation.  相似文献

The late Neolithic and early Bronze Age are periods marked by the construction of conspicuous concentrations of ‘ritual’ complexes, used for funerary rituals, seasonal gatherings and communal activities. Understanding the environmental context of monuments may provide detailed insights into relationships between the physical environment and the activities undertaken at individual monuments. Raised burial mounds (barrows) are generally assumed to have been constructed in open landscapes (the so-called ‘landscape openness’ hypothesis) thus rendering them highly visible in the surrounding landscape. This paper seeks to test to what extent vegetation (and in particular openness) around a dense concentration of barrows was actively managed, using three pollen sequences in close spatial juxtaposition to the archaeology. The local vegetation histories, supported by radiocarbon dating, demonstrate spatial differences in vegetation pattern both during the time of monument construction and use (c. 2000–1500 cal BC) and during subsequent periods. They do not support the ‘landscape openness’ hypothesis. This suggests that there is no single ‘blueprint’ for vegetation structure on and around these types of monument complexes. There is no evidence for major restructuring of the landscape during the early Bronze Age. The data describe a major transformation of the vegetation around 1500 cal BC (the Middle Bronze Age) in an area not known for archaeology of this date. This serves to emphasize the role of palaeoecology in augmenting the archaeological record of landscape re-organisation and transformation in prehistory.  相似文献

Event-history analysis is often used in the social sciences to study the occurrence of particular events over the lifespan of individuals and the impact of various factors on the rate at which those events occur. Like individuals, settlements can be analyzed and important events, such as founding or abandonment, can be studied using this method. Thus, as Richard Paine (1992) has noted, the technique can be useful in archaeological investigations of settlement processes. In this research we use it to explore the causes of settlement abandonment among a temperate shifting cultivators in an attempt to better understand the ecology of this adaptation and in order to evaluate the merits of the method. The sixteenth- and seventeenth-century Haudenosaunee (Iroquois) of northeastern North America present an interesting case study for applying event-history analysis to archaeological settlement dynamics because of the wealth of archaeological settlement data and detailed historic record that allows us to parse out historical factors and analyze the remaining ecological factors. We use event-history analysis as an alternative means for evaluating the relative and absolute effects of several variables that may have been predictive of the lifespan of settlements and the timing of their removal. The results suggest that the decision to move from a village was a complex process in which the population size of a village may have been the single most important, but not the only, determinant of settlement duration.  相似文献

The analytical performance of non-destructive portable X-ray fluorescence (pXRF) is compared with that of Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and Neutron Activation Analysis (NAA) for the elemental characterisation of a group of glazed stonewares from North-East Asia. As a non-destructive technique pXRF is potentially well suited to the elemental analysis of high value archaeological and museum collections but has yet to be critically evaluated for the analysis of archaeological stonewares. In this study we use multivariate evaluation to compare results from non-destructive pXRF in relation to ICP-OES and NAA analysis for the same group of samples. We conclude that, although pXRF is comparatively limited to a small number of major, minor and trace elements, these are sufficient to identify the same compositional groups as high dimensional ICP-OES and NAA datasets for this assemblage.  相似文献

Q methodology is receiving growing interest as a research technique. Its use of factor analysis and a well-defined methodological approach may appeal to quantitative researchers who need to investigate issues more commonly associated with qualitative techniques. Such issues frequently arise when investigating student learning. This paper suggests that, appropriately used, Q is a methodology to be embraced by quantitative and qualitative researchers alike. Drawing on work within the field of education, as well as two case studies, the method's utility is illustrated, and Q is suggested as another potential method for investigating the subjective views of our students.  相似文献

This article looks at the reconfiguration of the regulatory actors' network, as induced by the liberalization and reregulation processes in utility sectors. It investigates the changes in governance structures and patterns of collaborative ties between actors resulting from these processes. Applying stochastic actor‐oriented modeling (SAOM) to data on the liberalization of the Swiss telecommunications sector over two decades, we test whether and to what extent structural changes driven by liberalization and reregulation express themselves through network effects, that is, through changing patterns of interactions between political authorities, regulators, regulatees, and interest groups. Our empirical tests highlight a rearrangement of the regulatory network and a reorganization of relational patterns around new actors, such as the sector‐specific regulatory agency, coregulators, and new operators.  相似文献

In the present study Fourier transform infrared spectroscopy in the reflectance mode (FTIR-reflectance) – was performed on well preserved archaeological amber, originating from three Romanian archaeological sites of Roman and Byzantine cultures, which did not allow sampling material. Resulting spectra were subjected to multivariate data analysis (MDA) using Principal Components Analysis (PCA). In the light of the FTIR-reflectance bands of archaeological samples from the region 1275 to 1155 cm−1 and 900–600 cm−1 we could conclude that the samples from first two locations, Ro?ia Montan? and Nuf?ru, are made from amber of Baltic origin. In the case of the third location, Isaccea, we take into account the possibility of a mixture of raw materials, both Baltic and Romanian amber. These assertions are supported by statistical analysis and the historical context. Besides the FTIR spectra comparison or other analytical data, it is very important to correlate any information about the material (colour, conservation status, historical context, connections with other artefacts) and the statistical analysis in order to favour safe conclusions.  相似文献
