These conversations between Toni Negri and Sandro Mezzadra (November 2014–October 2015) focus on the politics of Mediterranean boundaries and situate migratory movements across the Mediterranean in the geopolitical context of the Eastern and Southern shore. Looking at the proliferation of wars around the Mediterranean region and reflecting on the legacy of the Arab Uprisings, Mezzadra and Negri revisit the concept of the “autonomy of migration” and critically interrogate its possible contribution to the field of migration and in terms of the current refugee crisis.  相似文献

Pigments appearing on ninth–twelfth-century AD-carved stucco, wall painting, and terracotta friezes excavated at Nishapur in north-eastern Iran were investigated by optical reflectance spectroscopy, micro X-ray fluorescence spectrometry (μ-XRF), X-ray diffractometry (XRD), micro-Raman spectroscopy (μ-Raman), and scanning electron microscopy (SEM). Many of the pigments identified including vermilion, red lead, hematite, limonite, carbon black, atacamite, calcite, and gypsum have been identified in previous studies of pigments used in later Islamic periods. However, a series of unusual pigments such as wulfenite, pyromorphite, phoenicochroite, and jarosite were also found in the present study. The association of kaolinite and alunite with limonite and other Fe-bearing yellow pigments points to a local provenance for these pigments. In addition, the presence of orpiment in the vermilion may be indicative that the vermilion was artificially manufactured. These findings suggest that pigment use and manufacturing during the ninth to eleventh centuries in Nishapur was still in a trial-and-error stage and the palette known from the twelfth century onwards had not yet been systematized.  相似文献

This is a response to the comments of Crockford and Kuzmin (2012) on our identification of Palaeolithic dogs from different European Palaeolithic sites. In their comments Crockford and Kuzmin (2012) present some errors, misunderstandings and misrepresentations that we remedy here. In our opinion, the early wolf domestication must be regarded as an intimate relationship between humans and canids including the breeding of the latter by prehistoric people, resulting in the European Palaeolithic dogs.  相似文献

This article reflects on the usefulness of photo elicitation in research with young people. As part of an Economic and Social Research Council-funded project exploring conflict and divisions in contested cities, teenagers living or attending schools in segregated areas of Belfast were presented with 11 photographs depicting the city's traditional ethno religious divisions, the new ‘post conflict’ consumerist city and youth subcultures. In response to each photo, the young people produced individual written comments and their opinions were fleshed out during follow-up focus group interviews. Drawing on these responses, the strengths and weaknesses of using photo elicitation in research with young people and its capacity to generate new insights into teenagers' spatial perceptions and experiences are outlined.  相似文献

Differential access to state-allocated incentives, based on socio-economic inequalities in rural society, is commonly assumed to be a key determinant of change in rural Africa. This article argues that, given the spatial diversity of Africa's rural political economies, analysis of the politics of rural change needs to be premised on an appreciation of the multiplicity of social relations through which rural power structures are configured. Data from a field study of a World Bank assisted agricultural development project in Lafia, Nigeria, are used to illustrate the manner in which spatial and inter-community variations in responses to commercialization, cultural divisions and the reorganization of political relations during the colonial era combine to sustain regional power structures which are defined by such differences. A comparative analysis of two village communities at opposite ends of the regional spectrum of commercialization is employed to demonstrate how such power structures provide a framework within which the political conditions of access operate to the advantage of both dominant socio-economic strata and members of particular cultural communities.  相似文献

Conference proceedings like this one, the outcome of a workshopheld in 2005, typically run dangers of suffering from variouspitfalls in that they compile a set of heterogeneous contributionsthat widely vary with respect to thematic focus and researchheuristics, and essential insights have often been publishedelsewhere before. This volume addresses an important and intenselydebated issue, comprises many enlightening chapters, and isedited by a team of renowned researchers; but its value is impairedby the typical imperfections. Ambitious expectations raisedin the editors’ preface, promising far-reaching consequencesof the book for theoretical and empirical work as well as forpractical policies supporting less developed countries are hardlyrealistic. Yet, how should a collection of 14 essays, albeitbeing written mostly by acknowledged academic experts, actuallymanage to produce breakthrough insights concerning the intricatetask of effectively promoting  相似文献

The Shurmai (GnJm1) and Kakwa Lelash (GnJm2) rockshelters are located in the Mukogodo Hills region of north-central Kenya. Sondages excavated at both sites allow preliminary reconstruction of their geological and archaeological histories. A total of 4782 lithic pieces were recovered from Shurmai, and 7862 from Kakwa Lelash. The earliest materials from Shurmai date to the late African Middle Stone Age (sometime before ca. 40,000 years bp), and those from Kakwa Lelash apparently date to the African Later Stone Age (sometime after ca. 40,000 bp). The raw material composition, technomorphological characteristics, and style of assemblages from these sites do not reveal whether modern human behavior emerged first in the Middle or in the Later Stone Age. However, the greater sophistication, systematization and efficiency evident in the patterns of resource use, tool manufacture, and style in the Later Stone Age components at Shurmai and Kakwa Lelash rockshelters is consistent with the view that the origins of modern human behavior are to be found in the Later, rather than the Middle, Stone Age in Africa.Les abris de Shurmai (GnJm1) et Kakwa Lelash (GnJm2) sont situés dans la région de collines de Mukogodo du Kenya nord-central. Les sondages creusés aux deux sites permettent la reconstruction préliminaire de leurs histoires géologiques et archéologiques. Un total de 4782 objets lithiques étaient récupérés de Shurmai, et 7862 à Kakwa Lelash. Les matériaux les plus tôt de Shurmai datent au fin de l'Age de la Pierre Moyen d'Afrique (avant ca. 40,000 ans avant le présent), et ceux de Kakwa Lelash datent apparemment au l'Age de la Pierre Récent d'Afrique (après ca. 40,000 ans avant le présent). La composition de matière première, les caractéristiques techno-morphologiques et le modèle des assemblages de ces sites ne révéle pas si le comportement moderne humain a émergé d'abord dans l'Age de la Pierre Moyen ou Récent. Cependant, la plus grand sophistication, systématisation et efficacité évident dans les configurations de l'utilisation de la ressource et dans la fabrication et style des outils de l'Age de la Pierre Récent des abris de Shurmai et Kakwa Lelash se conforme avec l'opinion que les origines de comportement moderne humain se trouvent dans l'Age de la Pierre Récent plutôt que dans l'Age de la Pierre Moyen dans Afrique.  相似文献

Class 13 and 14 Iron Age Scottish glass beads are a group of highly decorated beads of British origin or design, dating indicatively to the 1st and 2nd century AD and typically found in Aberdeenshire and Moray district (Guido, 1978, 85–9). Their distinctive stylistic characteristics and geographical segregation renders them ideal for the investigation of whether the glasses employed in their manufacture were imported rather than produced locally, and for the assessment of the technology used in the production of the deep colours. Studies performed in the 1980s on different specimens pertaining to the same Classes (Henderson, 1982) showed compositional characteristics differing from Iron Age southern British beads, suggesting a different source of glass for their manufacture. Here, a set of 19 beads which was never investigated before was analysed for 32 major, minor and trace elements using Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). The sample set shows good homogeneity in major and minor element composition, indicating the use of imported natron glass, with standardized composition typical of Roman glass of the period, also reflected in the recipes used for colouration. Evidence for the use of cullet and waste glass was found, which, along with the particularity of the design, suggests a local origin of the beads and possible production by native glassworkers.  相似文献
