Slipped and unslipped wares from Kampyr Tepe dated to the Hellenistic–Seleucid and Greco‐Bactrian periods stylistically resemble tableware from the Greek tradition. Since two pottery workshops have been recovered at the site, the aim is to shed light on the provenance and the production and consumption patterns of the tableware, as well as on the degree of technological influence from Hellenistic–Mediterranean traditions. The archaeometric characterization, consisting of thin‐section petrography, XRF, XRD and SEM–EDS analysis, was performed on 44 wares and three unfired locally made pondera, which were used as reference local elemental patterns. The study demonstrated the local origin of most of the wares, which were produced using a similar clay paste, following standardized techniques in modelling and firing, while surface treatments appear to be more diversified.  相似文献

Experimental tests on four full-scale exterior unreinforced reinforced concrete (RC) beam-column joints, representative of the existing non-conforming RC frame buildings, are carried out. The specimens have different longitudinal reinforcements (plain or deformed) and they are designed in order to be representative of two typical design practices (for gravity loads only or according to an obsolete seismic code). Different failure modes are observed, namely joint failure with or without beam yielding. The local response of the joint panel is analyzed. The different joint deformation mechanisms and their contribution to the deformability and to the energy dissipation capacity of the sub-assemblages are evaluated.  相似文献

城市犯罪中的非公共空间盲区及其综合治理   总被引:4,自引:1,他引:3  
城市犯罪中的空间盲区是形成犯罪载体的重要因素。本文在阐明城市犯罪空间盲区的产生机制及其综合治理的任务的基础上,重点分析了非公共空间盲区的防控脆弱性及其外在、内在的防控盲点,提出了治理此类盲区的工作思路,讨论了治理非公共空间盲区的外部环境和内部环境以及提高非公共空间警戒能力的工作途径。成功的综合治理可以对有效地预防犯罪、中止犯罪、制伏罪犯、消减犯罪危害性等起到积极作用,可以为城市犯罪的空间防控作出积极贡献。  相似文献

Excavation of the cemetery of the medieval priory of St. Mary‐without‐Bishopsgate, Spitalfields, London from 1998–2001, recovered the remains of over 10,000 individuals. Following initial assessment, skeleton 19893 was found to have suffered three cranial injuries caused by a sharp edged implement. The remains were those of a middle aged adult male of around 172.4 cm in stature, truncated at the hips by a later feature. The remaining elements were well preserved. The cranial injuries were well healed, suggestive of some degree of post‐traumatic care. Evidence of possible surgery was also found. Soft tissue complications would undoubtedly have followed the assault. Battle related trauma was considered, together with evidence of treatment. Whilst the demographic profile of the individual fitted a plausible one for a professional fighter of the medieval period, no firm evidence of occupation could be provided. The case study indicates both the ability of medieval people to survive major trauma and the wealth of information full analysis of the Spitalfields assemblage will provide the osteological community.

Electron spin resonance and infrared spectroscopic techniques have been used to examine the thermal and environmental deterioration of ivory from Nimrud, Iraq. It has been possible to ascertain the extent of ancient pyrolysis of the ivory with the former technique, and infrared spectroscopy has allowed an insight into the deterioration of the protein matrix of the ivory both in relation to, and independent from, thermal breakdown. Comparative spectroscopic studies of both ancient and modern ivory are also reported. The structural information obtained is discussed in the light of previously reported studies based upon chemical analyses.  相似文献

The quest for suitable data, data treatments and statistical methods for identifying the provenance of iron artifacts has led to a variety of analytical strategies. Researchers working on the problem have been slow to develop or adopt the use of multivariate statistical techniques, despite their successful implementation in other archaeomaterials sourcing frameworks. This paper explores the analytical potential of a comprehensive multivariate statistical strategy for identifying the primary production origins of bloomery iron artifacts using bulk chemical analyses of bloomery smelting slag and slag inclusions in iron artifacts. This strategy includes a multivariate model for identifying distinct slag inclusion types introduced during smelting and refining. Principal component analysis and linear discriminant analysis are then applied to smelting slag training sets to create multivariate provenance fields, the chemical distributions of which are defined by kernel density estimation. Single and multi-group evaluation methods are examined. Appropriate data transformations are discussed to facilitate the projection of the chemistry of “unknown” slag inclusions into the multidimensional space generated by the smelting slag groups of known provenance. The efficacy of this strategy is demonstrated through its application to a previously examined data set derived from three iron production experiments and a published archaeological example. Results indicate that an appropriately designed multivariate strategy can be an effective tool for evaluating provenance hypotheses for bloomery iron artifacts.  相似文献

The concept of the ‘therapeutic landscape’ has been widely applied by health geographers over the past decade and a half. Despite its broad application, the concept has been criticized. Some scholars, for example, have argued that it adopts an overly positive view of the health effects of therapeutics settings. Others have noted a lack of attention to gender. In this article we respond to these limitations by engaging with feminist research on women and drug use to critically examine women's experiences of the therapeutic space of drug treatment programmes. Drawing on in-depth interviews and participant observation conducted at two sites in southern Ontario, we examine the ways in which programmes' organizational logics, daily routines and social spaces are shaped by gendered assumptions about the nature of, and solutions to, women's drug use. In so doing, we contribute to a more nuanced and critically informed understanding of such landscapes.  相似文献

THE FINAL PHASE?     
This essay reviews the recent book by Carolyn Dean that seeks to elucidate the ways in which complaints about a “surfeit of memory” and the privileging of Jewish victimization during the Holocaust as unique and as the emblem of radical evil in our times has shaped discussions of victims in general, creating an environment in which groups vie for victim status as a means of validating their grievances and making claims for justice. The hostility to such claims has, Dean argues, created antivictim discourses that end up generating aversion toward victims, primarily by denying the validity of their claims to suffering and, in the case of Jews, projecting them as “perpetrators” in their neglect of the suffering of others. At the same time, Dean argues, the demand that victims narrate their suffering in the aesthetically constrained style of “minimalism” equally undermines the legitimacy of victims' memories by demanding that they be presented in an already mastered form, thereby erasing the very trauma that, in principle, such narratives seek to represent. At stake in the debates concerning Holocaust memorial consciousness and its proper modes of representation, this article suggests, are larger historiographical and ethical issues about how to integrate the horrors of the past and the traumatic experience of terror into the normal protocols of historical writing, which rely on distance, objectivity, and interpretive critique as governing procedures. To incorporate terror into historical representation will mean acknowledging and accepting as historiographically legitimate the differing status of analytically recuperated “facts” and victim testimony and finding a way to theorize the reality of “voices” from the past without assuming the necessary “truth” of what they convey.  相似文献
