The inorganic inclusions contained in amber fragments from Baltic regions and from the Simeto basin (Sicily, Italy) have been analyzed. The study, performed with the aid of a scanning electron microscope, shows specimen similarities and differences that are dependent on the place of origin. 相似文献

Shell beads are well established in the archaeological record of sub-Saharan Africa and appear as early as 75,000 BP; however, most research has focused on ostrich eggshell (OES) and various marine mollusc species. Beads made from various land snails shells (LSS), frequently described as Achatina, also appear to be widespread. Yet tracking their appearance and distribution is difficult because LSS beads are often intentionally or unintentionally lumped with OES beads, there are no directly dated examples, and bead reporting in general is highly variable in the archaeological literature. Nevertheless, Achatina and other potential cases of LSS beads are present at over 80 archaeological sites in at least eight countries, spanning the early Holocene to recent past. Here, we collate published cases and report on several more. We also present a new case from Magubike Rockshelter in southern Tanzania with the first directly dated LSS beads, which we use to illustrate methods for identifying LSS as a raw material. Despite the long history of OES bead production on the continent and the abundance of land snails available throughout the Pleistocene, LSS beads appear only in the late Holocene and are almost exclusively found in Iron Age contexts. We consider possible explanations for the late adoption of land snails as a raw material for beadmaking within the larger context of environmental, economic, and social processes in Holocene Africa. By highlighting the existence of these artifacts, we hope to facilitate more in-depth research on the timing, production, and distribution of LSS beads in African prehistory. 相似文献

When Pierre-Ambroise-François Choderlos de Laclos’s Liaisons dangereuses first appeared in late March 1782, it was an immediate succès de scandale. Laclos’s focus on his characters’ libertine psychology and his creation of a “monstrous” female villain, Merteuil, distinguished the novel from mainstream eighteenth-century French works. As an analysis of the novel’s reception demonstrates, Laclos’s suggestive portrayal of female sexuality and empowerment—and, specifically, of Merteuil—led first to the text’s association with dangerous works known as “mauvais livres” or “livres philosophiques” such as the Marquis de Sade’s Justine (1791) and the anonymous Histoire de Dom Bougre, Portier de Chartreux (1741), and later contributed to its classification as a pornographic work at the time the concept was invented in the early nineteenth century—and, ultimately, to its censorship in 1823. If the novel was devoid of explicitly sexual scenes, it nonetheless elicited such images in the minds of (at least some of) its readers and thereby caught the attention of the authorities. Les Liaisons dangereuses may be one of the most prominent historical cases of a book being banned not for what was depicted in its pages, but for the fantasies it inspired—providing a compelling twist to the adage that “pornography is in the eyes of the beholder,” or the mind of the reader. 相似文献

ABSTRACTThis paper reports on results of nonlinear analyses performed within the RINTC project on an RC building isolated with different systems (High Damping Rubber Bearings, High Damping Rubber Bearings and Flat Sliding Bearings, Friction Pendulum System) and designed according to the Italian design code. The seismic response has been evaluated under different seismic input levels of two sites with different hazard and by considering two Limit States: Global Collapse and Usability-Preventing Damage. The influence of seismic stoppers and modelling uncertainties is also evaluated. Results permit to compute the implicit collapse risk and to identify critical aspects of current design procedures. 相似文献

In Australia, e-government is continuously re-defining service boundaries. While this may be good in the case of transactional interactions, for example the online submission of tax returns, it is less clear that interpersonal services, such as working closely with the long-term unemployed, are best delivered digitally. We consider the impact of social services digitisation on vulnerable communities drawing on an analysis of remote Aboriginal communities. Digital uptake affords great opportunities, but it also carries risks. Some communities have no digital infrastructure and in certain cases traditional face-to-face services have been curtailed, leaving those not online with reduced assistance. We find that concerns about the ‘digital divide’ are well founded. Problems generated by e-government flow across boundaries and appear left to the third sector to resolve with the state playing an even more diminished role in the lives of disadvantaged citizens. 相似文献

This symposium draws attention to innovative and emerging research in Australian public policy exploring the interplay of governance, public policy and boundary-making. Conceptually and substantively, boundaries are fundamental to understanding policy outcomes, yet remain overlooked and undertheorised. We aim to contribute to public policy debates, in Australia and beyond, by provoking further reflection on this theme, in particular, the distributive effects of boundaries in policy-making; the blurring of boundaries implicit to governance frameworks; the crossing of boundaries, especially by policy-officials within and between institutions; the construction of boundaries to separate and marginalise; and the existence of temporal–spatial boundaries that demarcate jurisdiction and authority. In short, the study of governance and public policy-making is marked by multiple different types of boundaries but the way in which boundaries get drawn and redrawn is also suffuse with political contestation meaning they raise crucial questions about the exercise of power. 相似文献
