An Initial Assessment of Prehistoric Ceramic Production and Exchange in Northern Yoruba,North Central Nigeria: Results of Ceramic Compositional Analysis

Instrumental neutron activation analysis (INAA) was employed on 201 ceramic and clay samples fromthe Igbomina region of northern Yoruba in Nigeria. Ceramic data were obtained from 13 settlement sites spread over four Igbomina localities whose dates range between A.D. 1400 and A.D. 1800, and five raw clay samples from riverbeds and modern potters located in the Igbomina culture area. Quantitative analysis of the INAA data resulted in identification of four ceramic compositional groups that can be attributed to specific locales within the region. These results indicate that ceramics were moved within and among various Igbomina geographic areas and villages as well Ilorin (a Yoruba center located northeast of Igbomina).Results generated from this analysis indicate the tremendous potential for examining regional interaction in Yorubaland immediately before and during the Old Oyo period (fifteenth to the eighteenth century A.D.), a time of sociopolitical and settlement change. Instrumental neutron activation analysis (INAA) a été utilisé sur 210 échantillons de céramiques et d'argiles provenant de la région Igbomina située au nord de Yoruba au Nigeria. Les données sur les céramiques proviennent de treize villages situés dans quatre endroits dans Igbomina dont les dates varient entre 1400 A.D. et 1800 A.D., et cinq échantillons d'argiles crues provenant des fleuves et des potiers modernes situés dans la zone culturelle d'Igbomina. L'analyse quantitative des données de l'INAA a pu identifier quatre composition de groupements céramiques qui peuvent être attribués à des endroits dans la même région. Ces résultats indiquent que les céramiques avaient été déplacées dans l'enceinte et parmi les différents villages et régions d'Igbomina aussi qu'en Ilorin (centre Yoruba situé au nord d'Igbomina). Les résultats obtenus de cette analyse indiquent le potentiel énorme d'un examen minutuex des interactions régionales dans le pays Yoruba dans les temps antérieurement et durant la période de l'Ancien Oyo (15ème au 18ème siècle A.D.), une période marquée par des changements socio-politiques.     

Reverse Engineering the Ceramic Cooking Pot: Cost and Performance Properties of Plain and Textured Vessels

Ceramic cooking pots throughout the world vary in exterior surface treatment from smooth to roughly textured. An intriguing example of this variation occurred in the Puebloan region of the southwestern United States where cooking pots changed from scraped plain to highly textured, corrugated vessels between the seventh and eleventh centuries AD, and then reverted back to plain-surfaced by the fifteenth century. To investigate potential cost and performance differences between plain and corrugated cooking pots, a set of controlled experiments were performed, which document manufacturing costs, cooking effectiveness, and vessel durability. These experiments indicate that while corrugation may have increased manufacturing costs, neck corrugations improved vessel handling, upper body corrugations yielded greater control over cooking, and basal corrugations extended vessel use-life. Discerning the explanatory significance of these results for cooking pot change in the Southwest and elsewhere requires additional data on the contexts in which these pots were made and used.     

Implications of Petrographic Temper Analysis for Oceanian Prehistory

Petrographic examination of prehistoric Pacific potsherds in thin section allows robust distinctions to be drawn between indigenous temper sands derived from islands where sherds were collected and exotic temper sands derived from other islands, except that calcareous temper sands of reef detritus are undiagnostic of origin. Ceramic transfer or movement of ceramic raw materials from island to island can be detected because small islands serve as virtual point sources of noncalcareous terrigenous sands, and local island geology is controlled by systematic and well-known geotectonic patterns. Prehistoric Oceanian pottery was made locally on multiple islands, rather than being dispersed from a discrete number of ceramic centers, but limited ceramic transfer was widespread within nearly all island groups. As temper analysis is independent of ceramic typology, sherd tempers in common with obsidian artifacts and other manuports provide unambiguous physical evidence for migration, trade, or exchange within and between island groups.     

Transition From Wild to Domesticated Pearl Millet (Pennisetum glaucum) Revealed in Ceramic Temper at Three Middle Holocene Sites in Northern Mali

Imprints of domesticated pearl millet (Pennisetum glaucum (L.) R. Br.) spikelets, observed as temper in ceramics dating to the third millennium BC, provide the earliest evidence for the cultivation and domestication process of this crop in northern Mali. Additional sherds from the same region dating to the fifth and fourth millennium BC were examined and found to have pearl millet chaff with wild morphologies. In addition to studying sherds by stereomicroscopy and subjecting surface casts to scanning electron microscopy (SEM), we also deployed X-ray microcomputed tomography (microCT) on eleven sherds. This significantly augmented the total dataset of archaeological pearl millet chaff remains from which to document the use of the wild pearl millet as ceramic temper and the evolution of its morphology over time. Grain sizes were also estimated from spikelets preserved in the ceramics. Altogether, we are now able to chart the evolution of domesticated pearl millet in western Africa using three characteristics: the evolution of nonshattering stalked involucres; the appearance of multiple spikelet involucres, usually paired spikelets; and the increase in grain size. By the fourth millennium BC, average grain breadth had increased by 28%, although spikelet features otherwise resemble the wild type. In the third millennium BC, the average width of seeds is 38% greater than that of wild seeds, while other qualitative features of domestication are indicated by the presence of paired spikelets and the appearance of nondehiscent, stalked involucres. Nonshattering spikelets had probably become fixed by around 2000 BC, while increases in average grain size continued into the second millennium BC. These data now provide a robust sequence for the morphological evolution of domesticated pearl millet, the first indigenous crop domesticated in western Africa.

     

商墓中的毁器习俗与明器化现象

<正>用打碎了的陶、铜、玉器随葬,或者用非实用性的明器随葬,是商文化墓葬中常见的现象。前者流行于二里岗文化时期,后者则以殷墟文化时期为盛。这两种看似不相关的习俗之间,却有着内在的联系。它们在商代中期的此消彼长,反映了商代丧葬观念的变化。本文拟对此进行简单探讨。     

Developmentalities and Calculative Practices: The Millennium Development Goals

Abstract: This paper focuses on wide‐ranging governmental discourses that enable new ways of shaping social and economic affairs in the field of development. Directing particular attention to the Millennium Development Goals, we refer to these discourses as developmentalities. As a form of governmentality produced through these Goals, developmentalities draw on the turn of the century to recast certain development problems and offer reformulated solutions to these problems. We argue that they rely on three forms of neoliberal rationalities of government—information profiling, responsibilization, and knowledge networks, and their calculative practices, to shape global spaces and new capacities for individuals and social groups. Our analysis is based on extensive policy documents, reports, and development initiatives affiliated with the United Nations and other organizations, as well as insights derived from in‐depth interviews and conversations with United Nations policy and research personnel from the Food and Agricultural Organization (FAO) and the United Nations Educational, Scientific, and Cultural Organization (UNESCO).     

Temper mixture models and assessing ceramic complexity in the emerging Tarascan state

This study presents compositional data from ceramics drawn from surface survey and controlled excavations from three prehispanic sites within the relatively small Lake Pátzcuaro Basin, representing a ceramic sequence stretching nearly 1500 years, from the Preclassic to Late Postclassic Tarascan state (ca. 50 B.C.–1525 A.D.). Using neutron activation analysis, we identify compositional groups and model the importance of volcanic materials as temper in the construction of prehispanic ceramics by matching mathematical simulations of clay–ash mixes to the compositional groups. Rather than discreet clay resources and spatially circumscribed production, we argue for a broadly dispersed and highly varied organization of pre-Tarascan and Tarascan state ceramic production in which the potters' distribution and use of specific volcanic ashy additives, not clays, structured the organization of production.     

The Faragola Ceramic Collection: Ceramic Production,Consumption and Exchange in Seventh‐Century Apulia

A collection of 30 ceramic samples, 16 of coarse wares and 14 of fine painted wares, have been investigated by optical microscopy, scanning electron microscopy, inductively coupled plasma optical emission spectrometry, inductively coupled plasma mass spectrometry and neutron activation analysis. Further samples of clayey sediments, both locally outcropping and found within the settling tank, have been submitted to the same analytical techniques for comparison with the ceramic collection. The results demonstrated that local clayey sediments were used as received for the production of coarse wares. The same raw materials were sieved and/or refined by decantation for the production of fine painted wares, which, in fact, provided results that were perfectly comparable with those for the clayey raw materials found within the settling tank. The Faragola productions were distinguished from the neighbouring Apulian productions according to petrographic features (the presence of leucite‐bearing volcanic rocks and Mn‐rich wads) and their bulk chemical composition.
