Boundaries are Made for Crossing: The feminized spatiality of Puerto Rican Espiritismo in New York City

Espiritismo is a system of ritual healing indigenous to the Caribbean. Nearly 3 years of fieldwork in an Espiritismo worshipping community in Manhattan has produced a rich and textured source of ethnographic information that is analyzed in terms of its feminized spatiality. The central figure in this community is Maria; the priestess/medium who negotiates the exigencies of this world and the world of the spirits through trance-possession performance. Her articulation of Espiritismo uses the boundaries between self and community, male and female, Catholic and non-Catholic, the human world and the spirit world, and racial identities as resources for solving problems of well-being such as poor health, lost love, and economic deprivation for herself and her community of devotees. Maria's body is the primary site where these issues are resolved in that her body (re)presents, (re)produces and (re)valorizes the Espiritismo community's use of (in)visibility, particularity, trance-possession and inclusivity as a means for healing everyday problems in familiar spaces.     

Factors Controlling Pre-Columbian and Early Historic Maize Productivity in the American Southwest, Part 2: The Chaco Halo, Mesa Verde, Pajarito Plateau/Bandelier, and Zuni Archaeological Regions

Chemical and nutrient analyses of 471 soil samples from 161 sites within four archaeological regions (Pajarito Plateau/Bandelier, Zuni, Mesa Verde, and the Chaco Halo) were combined with historical climate data in order to evaluate the agricultural productivity of each region. In addition, maize productivity and field-life calculations were performed using organic-nitrogen (N) values from the upper 50 cm of soil in each region and a range (1?C3%/year) of N-mineralization rates. The end-member values of this range were assumed representative of dry and wet climate states. With respect to precipitation and heat, the Pajarito Plateau area has excellent agricultural potential; the agricultural potentials of the Zuni and Mesa Verde regions are good; and the agricultural potential of the Chaco Halo is poor. Calculations of N mineralization and field life indicate that Morfield Valley in Mesa Verde should be able to provide 10 bu/ac of maize for decades (without the addition of N) when organic N-mineralization rates exceed 2%. Productivity and field-life potential decrease in the following order: Zuni, Mesa Verde, Bandelier, Chaco Halo. The Chaco Halo is very unproductive; e.g., 10 bushels per acre can be achieved within the Halo only from soils having the highest organic N concentration (third quartile) and which undergo the highest rate (3%) of N mineralization.     

Starch grain analysis for groundstone tools from Neolithic Baiyinchanghan site: implications for their function in Northeast China

Large numbers of groundstone tools have been uncovered from archaeological sites in the Early Neolithic period in China. Traditionally they are often regarded as agricultural tools for processing cereals. In this paper we report preliminary starch grain analysis of groundstone tools from Baiyinchanghan site to gain a better understanding of use of these tools in the Northeast China. We found that starch grains on these groundstone tools are most likely from Quercus sp. The result of this study indicates that many groundstone tools for the Early Neolithic period were used to process wild and domesticated plants alike.     

美索不达米亚早期食物生产的生态学——史前农人与牧人开发一系列位置相邻却差异显著的气候区

大美索不达米亚,在这里广泛地定义为阿拉伯河（Shattal—Arab）各支流汇人的整个地区,长期以来它是公众兴趣和学术研究的舞台。近年来,关注点转向这样一个事实,即它是世界上少数几个农业与动物饲养独立出现的地区之一。虽然已有许多近东粮食生产起源方式出色的文化历史学复原,但是大多数并未直接解决感兴趣的非专业人士最常提出的一些生态学问题。本文研究其中的某些问题。     

Optically stimulated luminescence dating of heated materials using single-aliquot regenerative-dose procedure: a feasibility study using archaeological artefacts from India

Optically stimulated luminescence (OSL) dating of heated/fired materials of archaeological importance from various parts of India was attempted. A single-aliquot regenerative-dose (SAR) procedure was used for palaeodose determination in the quartz grains extracted from the heated materials using the luminescence produced by blue light stimulation. In most pottery samples, the palaeodose obtained using SAR-OSL is ∼6% lower than the palaeodose measured using thermoluminescence (TL) method. Broadly, there is good agreement between the SAR-OSL and TL ages of the artefacts and their archaeologically expected ages. The results suggest that routine dating of heated/fired materials using the SAR-OSL procedure is more practicable, especially when the TL sensitivity of the quartz grains is poor and availability of datable material is limited.
