With a dramatic expansion in quantity and variety, the amount of recent history source materials has surpassed the sum total
of those available for all earlier dynasties. At the same time, compared with the case in ancient history study, the obscure
boundary of source materials has made it difficult for historians to locate and obtain what they need for their research.
Since it is impossible to exhaust or to ascertain the boundary of relevant sources, scholars either retreat into narrower
fields or make arbitrary interpretations of materials, both contributing to the loss of orientation in historical study, and,
for that matter, eroding the integrity of historiography. Historians must, first and foremost, acquire a comprehensive understanding
of the discipline before they can undertake studies on any particular subject, which is the proper way to conduct historical
study and to avoid short-sightedness or a tunnel vision of the scene. The author of this paper believes that it is urgent
to resolve the dilemma in preserving and utilizing source materials by publishing as many materials as possible efficiently
so that scholars on recent Chinese history can stand on an equal footing as far as materials are concerned. Only in this way
will they be able to undertake deeper investigations, to uncover the complex correlation between source materials and historical
study, and ultimately, to contribute to recent history study as a whole. 相似文献

Charcoal is a valuable source of archaeological and palaeoenvironmental proxy data. However growing evidence suggests that production conditions can strongly influence post-depositional alteration of charcoal. Consequently, both reconstruction of production temperature and understanding of the potential for diagenetic alteration are of great interest. Here, we use mean random reflectance (Romean) in conjunction with other chemical characterization methods to address these questions. Romean was obtained for a suite of modern analogue charcoal, produced under controlled conditions, and for a series of natural charcoal samples, obtained from archaeological and palaeoenvironmental deposits. Romean proves to be a robust measure to assess formation temperature for samples produced at 400 °C and above, even after exposure to highly oxidizing conditions. Romean is also useful for samples formed between 300 °C and 400 °C. However, if an assemblage of charcoals has been exposed to oxidizing conditions, lower temperature charcoals may be preferentially lost. It is apparent that charcoal produced at lower temperatures is more highly susceptible to chemical oxidation, and that there is a continuum in charcoal degradation potential, dependant upon fuel material and production conditions. 相似文献

This research focuses on the case of international chains facingsignificant competition from domestic chains in advanced industrializedeconomies. In this article, I question the assumptions behindthe perceived, simultaneous process of globalization and retailconcentration by taking the cases of the world's two largestretailers, Wal-Mart and Carrefour, entering the Japanese marketin the early 2000s. Both retail TNCs have so far failed to meetinitial high expectations for their performance. I argue thatthere is a structural paradox inherent among retail TNCs, whichis expressed as contradictory forces between standardizationand localization. Empirical evidence is provided on how theseforces complicate retail TNCs front-end (store-front)and back-end (distribution) operations in the case of Japan.Emphasis is placed on the role of oligopoly in the retail sectorand how its absence affects retail TNCs operation inforeign markets. 相似文献

Insects are present in most archaeological contexts as a result of both natural and cultural processes. Insect data can be used to address a number of issues, including environmental reconstruction, forensics, identification of domesticates, taphonomy, and diet. This paper focuses on the archaeology of insect use in antiquity: their collection, processing, and storage and the archaeological manifestations of those activities. Consideration also is given to the incorporation of insect data into settlement/subsistence models. 相似文献

The structures and compositions of modern and fossil charcoal samples were compared in order to evaluate charcoal degradation processes in archaeological sites. Modern charcoal samples produced in campfires contain two major phases: graphite-like microcrystallites and a non-organized phase. These phases create a mosaic-like structure with differing relative proportions depending on the taxonomic source of the wood used. Fossil charcoal samples (Tel Dor, Israel: 3000 years BP and Kebara Cave, Israel: 40,000 years BP) also contained the graphite-like microcrystallites and the non-organized phases, but were clearly altered compared to modern charcoal. The graphite-like phase of the fossil charcoal has much higher electrical resistivity, and its ESR properties show that it has markedly altered surface electronic states. Infrared spectra show the presence of additional carboxylate groups. Oxidation has therefore altered the structure. This appears to be a “self-humification” process that affects the graphitic component, and probably the non-organized phase as well. 相似文献

Resumen El World Archaeological Congress puede servir como un recurso esencial para los grupos indígenas que deseen participar completamente
en el ejercicio de la arqueología. Las experiencias de los nativos americanos con la arqueología se pueden comparar con las
de otros grupos indígenas, y el código ético, del WAC ilustra hasta que punto esta organización se toma en serio su compromiso
de trabajar en cooperación con las comunidades. En este artículo se presentan algunas metas que el WAC tiene que plantearse
en relación con los grupos indígenas, incluyendo la educación, el establecimiento de redes de trabajo, la profesionalidad
y la gestión de los yacimientos arqueológicos.
Résumé Le congrès Mondial d'Archéologie peut être une ressource vitale pour les indigènes désireux de participer pleinement à la profession d'archéologue. Les expériences indigènes américaines avec l'archéologie sont semblables à celles d'autres groupes indigènes et le code l'éthique du WAC démontre jusqu'à quel point cette organisation est sérieuse quant au travail et à la coopération avec les communautés. Il y a plusieurs points de considération pour le WAC au sujet des peuples indigènes, tels que l'éducation, le réseau de communication, le professionalisme et la gestion des sites culturels.相似文献

The issue of fairness often is central within environmental policy debates. The recent proliferation of state and local comparative risk projects for informing the selection of environmental policy priorities offers an appropriate setting to explore the issue of procedural fairness in risk-based decisionmaking. This paper describes and evaluates the process by which one of the initial state comparative risk projects, Washington's “Environment 2010,” attempted to include a broader range of participants in identifying, assessing, and generating preferred management strategies for a wide range of environmental hazards. The Washington case study suggests that comparative risk projects can be fairer procedurally, but that significant barriers remain. Noting that greater procedural fairness does not necessarily produce greater substantive fairness, the paper concludes that more attention needs to be directed at the process by which comparative risk projects translate their consensus upon risk priorities into subsequent actions. 相似文献

Secondary refuse contains a wealth of information on the people who generated it. This article identifies some means by which archaeologists can identify and characterize secondary refuse aggregates — localized, high-density deposits of artifacts that have been discarded away from their place of use. A variety of studies of archaeological deposits — from prehistoric and historical archaeology, ethnoarchaeology, and modern material culture studies — provides hypotheses and a comparative database for discussion. I suggest that socioeconomic and demographic factors operating in a society greatly affect the composition of secondary refuse aggregates and propose some hypotheses regarding the directions and magnitudes of these relationships. 相似文献
