Reconstructing ancient Maya animal trade through strontium isotope (87Sr/86Sr) analysis

This study explores the potential for using strontium isotope analysis (⁸⁷Sr/⁸⁶Sr) to study ancient Maya animal exchange. Traditional zooarchaeological methods of studying trade rely on the identification of animals found outside their natural geographic or habitat ranges. Isotopic analysis provides an additional means of identifying and sourcing non-local animals. ⁸⁷Sr/⁸⁶Sr values from Maya zooarchaeological remains indicate that regional and long-distance transport and exchange of animal goods was more common than previously recognized. Widely distributed animals including deer and peccary were among the animals exchanged, which questions their common interpretation as locally-acquired resources. The isotopic results contribute to our understanding of how animal products were integrated into Maya economic and exchange networks. The research is also relevant to human mobility studies in Mesoamerica.     

The Invisible Hand that Rocks the Cradle: On the Limits of Time Use Surveys

Almost every intervention in the field of international agricultural development — from microcredit finance to fertilizer subsidies to trade policy — has come to recognize gender, and relationships within households, as important. Yet most interventions continue to treat the household as a ‘black box’, with changes within the household measured by the effects on income, anthropometry, health, or other secondary metrics within bargaining models. In this context, there has been increasing interest in time use studies as a way to peer inside this black box. This article offers a review of methods and identifies some of the difficulties facing time use studies in capturing intrahousehold dynamics, and presents the results of a two‐season simultaneous activity time use study in Malawi which aimed to address these difficulties. The results suggest significant limitations to time use surveys. The kinds of reproductive labour that often interest researchers may be invisible to the women responding to time use surveys, with the result that care work is dramatically under‐reported. The authors discuss the implications of the divergence between researchers’ concerns and the women's reports of their lives for time use surveys, and for feminist development research methods more broadly.     

Toward Historical Ethnography: Notarial Records and Family History in the Middle Ages

One can easily use nineteenth-century tithe data of England and Wales in a Geographic Information System (GIS) to analyze a range of subjects, for example, land use, productivity, land ownership, or tenancy. Making the tithe data GIS ready, on the other hand, is a nontrivial matter. The tithe data consist of two main types: spatial, that is, the tithe map, and nonspatial attribute data linked to the map. The tithe therefore has the characteristics of a GIS, albeit in paper form. The author outlines the process of creating the structures for building a data repository that allows the storage and dissemination of both tithe schedules and maps in a single GIS-ready system. The author chose Oracle to host the repository. The Oracle Spatial module allows storage of both spatial and attribute information. Oracle also provides the means of serving data to users via the Internet.     

The Natural Contract: From Lévi‐Strauss to the Ecuadorian Constitutional Court

In 2008, the Ecuadorian Constituent Assembly became the first juridical body in the world to legalize what Michel Serres might have called a ‘natural contract.’ With the assistance of the U.S.‐based Community Environmental Legal Defense Fund, representatives at the Assembly in July of 2008 re‐wrote their 1998 constitution to include a landmark series of articles delineating the rights of nature — a notion long familiar to Indigenous communities in the Andean region, actively propagated by anthropologists like Claude Lévi‐Strauss at the French National Assembly as early as the 1970s, and often mocked by mainstream Western jurists for its conceptual confusion about the sorts of entities that can properly be said to have rights. Drawing on the experiences of activists currently engaged in the first national‐level lawsuit to make use of these rights as well as a range of both activists and non‐activists involved in alternative implementations of them, the article explores the possibilities, limitations, and paradoxes of this extension of rights‐based discourse. At a time when the natural world is increasingly being talked about at the United Nations and elsewhere not as a ‘rights‐holder,’ but as an ‘ecosystem services provider,’ I suggest that while the discourse of ‘rights' signals promising shifts in how Andean governments are conceptualizing agency and responsibility in ways that productively break with the trend toward marketization, it also runs the risk of providing the administration with symbolic cover for its intensifying commitment to what Eduardo Gudynas has called, a ‘new extractivism.'     

Voluntary Environmental Programs in the Public Sector: Evaluating an Urban Water Conservation Program in California

Solving conflictual environmental policy problems is increasingly falling under the purview of local governments and public agencies. Nonregulatory approaches, such as the development of voluntary environmental programs (VEPs), could offer a useful policy alternative as they often have greater political traction and flexibility. However, there has been little work examining the use of VEPs in the public sector. This article uses a new dataset from California to examine how political institutions affect decisions by local governments and public agencies to participate in a voluntary urban water conservation program and whether this program has improved the water conservation performance of its members. The results show that special district governments, private utilities, and water suppliers dependent on purchased water are more likely to participate in the program and to join early. However, urban water agencies that have joined the program have not reduced their per capita water use more than those that have not. These results underscore the influence of political institutions in public‐sector decision making and demonstrate that, as in the private sector, commitment to a VEP by local government and public agencies does not guarantee implementation or environmental improvements. While voluntary programs offer political and administrative advantages, in order for VEPs in the public sector to be effective they must be accompanied and supported by credible enforcement mechanisms, performance standards, and rigorous monitoring programs.     

Refining the identification of native American pipestone quarries in the midcontinental United States

Midcontinental pipestone quarries in Missouri, Minnesota, Wisconsin, Illinois, Ohio, and Kansas were utilized by a number of native cultures from 5000 YRBP through historic times. Except for Gunderson’s pioneering work on catlinite, the mineralogy of these sources was poorly understood until recently. For fifteen years, a University of Illinois team of archaeologists and geologists has used well-established mineralogical methods (X-ray diffraction [XRD] and reflectance near-infrared spectroscopy [NIS]) to identify and characterize nine pipestone quarries and match sources with archaeological artifacts from major Hopewell and Mississippian culture sites. NIS analyses of raw materials from nine major pipestone quarries show distinct mineralogical differences between sources but relatively uniform composition within each source. The major distinguishing minerals estimated from NIS spectra match very well with earlier results from XRD and inductively-coupled plasma (ICP) analyses. Results demonstrate that NIS is a reliable non-destructive technique for discriminating between midcontinental pipestones and for sourcing pipestone artifacts.
