The Hili archaeological complex in Al Ain (U.A.E.) is important for its wealth of third-millennium BC Umm an-Nar burial and settlement sites. Two of the most significant burial sites are Tomb N at Hili and Tomb A Hili North. The latter is a classic circular Umm an-Nar monumental grave, while Hili N is a pit-grave, one of only two Umm an-Nar period pit-graves discovered so far in the U.A.E. Both of these tombs contained the remains of hundreds of individuals, in the case of Tomb A Hili North, more than 300, while around 600 people had been deposited in Hili N. Both population groups have been the subject of anthropological and artefactual analyses and a comparison of the findings help to shed light on the chronology of the end of the Umm an-Nar period.  相似文献

Few anthropologists today would consider using the term 'tribe' as an analytical category, yet it has become a focal point for military commanders and other leaders prosecuting the wars in Iraq and Afghanistan. Specifically, US-led occupation forces in both countries have begun pursuing 'tribal' strategies in which they have attempted to forge alliances with 'sheiks' and local power brokers. This article examines the reasons for the rapid rise of 'tribal' discourses, the role of social scientists in their propagation and the possible consequences for Iraqis and Afghans. It concludes by comparing these processes to ethnographically-informed pacification efforts initiated in the late 1800s and early 1900s by the European powers, and by suggesting that anthropologists can potentially play a critical role by challenging persistent, damaging assumptions.  相似文献

This article examines the reported use of ‘big data’ analysis by Cambridge Analytica in support of Donald Trump's presidential campaign. It investigates the transformations enveloping the overlapping worlds of politics, technology and social science. In particular, it critically reviews new developments in the field of psychometrics that have enabled researchers to harvest vast quantities of data by accessing social media platforms such as Facebook. The article also assesses claims that predictive analytics and ‘psychographics’ led to Trump's unexpected victory. The article concludes with a broader discussion about the state of political discourse in an era of digital communication.  相似文献

We present a preview of our work for a critical anthology of medieval and pre-medieval fantastic folklore narratives about animals in the human body. These are generally referred to among English-speaking scholars as ‘bosom serpent’ legends. In particular, we provide here two of the most ancient texts from the section of the anthology on medieval Scandinavia. We also offer two little-known narratives, a medieval Latin saint’s life and one from the Byzantine Greek world.  相似文献

Theories and data do not always fit and sometimes are sources of conflicts among scientists. This is the case of a morphological structure, the perineuronal net, which was denied on the basis of an ideological conflict between two giants of neurosciences: Camillo Golgi and Santiago Ramón y Cajal. The perineuronal net is a reticular structure enveloping many neurons. Originally reported by Golgi in 1893 and 1898 and confirmed by several authors before the turn of the century, the perineuronal net was used by Golgi to support the reticular theory of the organization of the nervous system. Ramón y Cajal, the paladin of the neuronal theory who had also observed this anatomical structure, denied its existence suggesting that it was a fixation artifact. After Cajal's statements, only a few Italian scientists continued to work in this field, and after the 1930s the perineuronal net was forgotten. Only the recent advances in histochemical and immunocytochemical technology confirmed the existence of this structure opening new fields in functional neuroanatomy and neuropathology.  相似文献

Prehistoric pottery decorated with incisions or impressions filled with white and seldom coloured inlays is well documented in the archaeological literature, but the related in-depth archaeometric studies are sporadic. 43 decorated ceramic shards, dating from the Neolithic to the Bronze Age, and an Iron Age fibula from the archaeological site of Castello di Annone (Piedmont, North-Western Italy) were analysed with FTIR, Raman and XRPD for characterization of the ornamental pigments forming these inlays. Few white components were used as fillers, namely talc and bone ash (hydroxyapatite – Bone White), often as a mixture and seldom accompanied by other pigments (i.e. kaolinite and presumably secondary calcite). Comparison with freshly-heated biogenic hydroxyapatite proved that ancient Bone White pigment was calcined at about 900 °C. Such a process was kept separate from pottery firing as these white mixtures show absence of talc degradation by-products and sporadic presence of kaolinite, implying these ceramics were decorated only after firing in furnace. Actual presence of fluorapatite in bone ash could allow dating with the Fluorine Method, but lack of fluorine detection with SEM-EDS causes such an attempt to be impracticable so far. A pilot comparative study with a restricted but representative group (11) of coeval finds from other sites of Piedmont suggests that while recurrence of talc prevails in Castello di Annone from the Neolithic throughout the Bronze age, massive use of bone ash (Bone White) becomes widespread in the close Iron Age settlements, possibly consequent to a more efficient handling of its production technology.  相似文献

This paper examines the level and evolution of polarization in regional per capita income in the European Union between 1977 and 1999. In this analysis, non-parametric estimation techniques are combined with the calculation of various polarization measures. The results obtained suggest a decrease in regional polarization in the European context during the period analysed, as a consequence of various factors, at times working in opposite directions. The findings also reveal the existence of discrepancies between the evolution of polarization and regional inequality. Finally, the analysis carried out highlights the importance of the role played by the national component and the spatial dimension in the formation of homogeneous groups of regions linked by similar development levels in the distribution under study.  相似文献
