Oxygen isotope analysis of California mussel shells: seasonality and human sedentism at an 8,200-year-old shell midden on Santa Rosa Island,California

To evaluate coastal settlement and land use strategies among maritime hunter-gatherers, we analyzed oxygen isotope (δ¹⁸O) data from 131 marine carbonate samples from 21 California mussel (Mytilus californianus) shells obtained from a large ～8,200-year-old shell midden (CA-SRI-666) on California’s Santa Rosa Island. Seasonal distributions of the isotopic data were assigned using a paleo-sea surface temperature model created by comparing modern sea surface temperatures (SST) to a fully profiled ～8,200-year-old shell. For 20 additional shells, we used two sampling strategies to compare season-of-harvest inferences and explore whether the Early Holocene site occupants were sedentary. Estimated season-of-harvest differed by 35 % between the two sampling methods, corroborating recent isotope analysis of an 8,800-year-old shell midden on San Miguel Island. Shellfish appear to have been collected year-round at CA-SRI-666 from intertidal or subtidal water temperatures similar to modern SST in the vicinity of eastern Santa Rosa Island. The isotope results are consistent with other evidence from CA-SRI-666 that suggest that the site served as a residential base for relatively sedentary maritime people.     

Postclassic Maya slips and paints and their relationship to socio-political groups in El Petén,Guatemala

LA-ICP-MS analysis of the chemical composition of the exterior slips and red and black pigments used for painted decoration of the three Postclassic Maya slipped ceramic wares suggests that the Itzá and Kowoj used different pigments for exterior slips and decorative motifs. Additionally, different slips and paints were used depending on vessel form and decorative program (red, black, or red-and-black painting or incising). When examined with previous ceramic paste chemical analyses, the data aid in better understanding the changing socio-political alliances and dominance relations in central Petén at the eve of Spanish contact.     

Gender,Retail Employment and the Clothing Commodity Chain

This article analyzes the conditions of employment in fashion retailing, arguing that fashion retailing constitutes a distinct sector of retailing. The fashion commodity chain is characterized by a unique spatiality and temporality and as a result, female retail workers share much in common with women situated at production, advertising and consumption sites in the chain. Given that many of the issues women confront at different sites are similar, the sector is amenable to organizing across the chain.     

‘Like it,don’t like it,you have to like it’: children’s emotional responses to the absence of transnational migrant parents in Lombok,Indonesia

ABSTRACT

This article explores the experiences and emotions of children in rural East Lombok, Indonesia, who stay behind with relatives or neighbours while their parents leave the country for work. The article contributes to recent scholarship of children’s experiences of transnational migration in Southeast Asia by drawing out the complex emotions of children who stay behind. Based on research conducted in four ‘sending’ villages, the article describes children’s lived experiences of their parent’s transnational migration, and their intense feelings that whether they ‘like it or don’t like it’, they have no choice but to acquiesce to their parents’ long, often indeterminate absences. The research suggests that stay-behind children are entangled in community anxieties pervading the emotional economy of transnational migration, including the embodied emotion of shame (malu) which shapes children’s responses to parental absence. By focusing on children’s own views and experiences, we contribute to growing debates about the implications of migration for children’s rights and well-being in Southeast Asia.     

Rethinking the regional knowledge production function

The knowledge production function is a questionable device foridentifying the determinants of commercial patenting. Adaptedfrom firm level analysis, it implicitly assumes that some mechanismexists to transfer research and development inputs across institutionsto maximize invention output. Augmenting the approach with regionalstructure variables risks confounding causes and effects, becausethese conditions determine research and development in the firstplace. We contrast a knowledge production function and a regionalstructure model to identify the determinants of commercial patentingin US states in the period 2002–2004. Results show thathuman capital, specialized knowledge flows, urbanization andindustry dominance in technical advance drive commercial patenting.     

The Myrick Park Mounds (47Lc10), an Effigy Mound Site in Western Wisconsin

The earliest documented excavation of an effigy mound group by a professional archaeologist occurred in 1883 when Frederic Ward Putnam and local acquaintances excavated portions of four mounds at the Myrick Park site (47Lc10) in La Crosse, Wisconsin. Putnam worked on one effigy (similar to the short-tailed turtle form) and three conical mounds. Theodore H. Lewis visited the site in 1885 and mapped one additional conical mound. We examined documentation and collections housed at the Peabody Museum of Archaeology and Ethnology at Harvard University. Artifacts include a portion of a Madison Cord Impressed jar (a common Effigy Mound offering) and a trailed rim sherd similar to terminal Late Woodland types. Human remains represent a minimum of 23 individuals: 18 adults and 5 subadults. Dental and skeletal evidence indicates a relatively healthy population with low levels of nutritional deficiency, early life stress, and trauma, similar to other regional Late Woodland populations.     

Cranial suture closure and its implications for age estimation

Three age estimation techniques using ectocranial and/or endocranial suture closure are tested on a sample of known age from Spitalfields, London in order to determine the value of cranial suture closure as an indicator of age at death. The three techniques are those proposed by Acsádi and Nemeskéri, Meindl and Lovejoy and Perizonius. Results indicate that the Acsádi and Nemeskéri technique, which is based on endocranial sutures, can be used to distinguish young and middle-aged individuals in the Spitalfields sample but gives no information for crania over the age of 50 years. Age estimation using the Meindl and Lovejoy and Perizonius (Old system) techniques, which use ectocranial sutures, was found to be subject to a number of complicating factors, of which sexual dimorphism in the rate and pattern of closure is the most significant. A method of estimating age at death based on both endocranial and ectocranial suture closure is developed on the basis of the Spitalfields sample. The technique attempts to overcome some of the problems associated with both intra- and interpopulation variation in cranial suture closure. For a truly accurate age-estimation technique based on cranial suture closure we would need to know more about the causes and functions of suture closure in human populations.
