Insight Into

In the Andean region, spindle whorls have been the subject of archaeological analysis less often than other artifact classes, such as pottery. Nevertheless, spindle whorls may have much more to contribute to archaeological interpretations of production, status, and exchange patterns than previously acknowledged. The case study presented here examines the spindle whorl collection from the site of El Purgatorio, Peru, the capital city of the Casma polity (ca. A.D. 700–1400). Spindle whorls were not only expertly crafted utilitarian tools for spinning yarn, but also items of personal adornment, symbols of wealth or status, and possible indicators of intra-polity exchange patterns. The analysis of spindle whorls in regard to form and function provides insight into Casma social and economic organization. The spindle whorls discovered at El Purgatorio also reflect varying degrees of standardization and technical knowledge, suggesting that at least some may have been manufactured by specialists in metallurgical and ceramic workshops.

AbstractArchaeologists often overlook museum collections for research purposes due to concerns about the representativeness of the artifacts in the collection. Such concerns can be addressed by comparing non-scientifically produced collections to collections of known standing, such as those from more modern projects, using the same exploratory data analysis and basic statistical methods that archaeologists use to compare sets of artifacts in other situations. As a case study, this article compares spindle whorls recovered during the 2007 excavations at the Aztec site of Calixtlahuaca with two museum collections of whorls attributed to the site. A variety of metric and non-metric traits were recorded for each item in the three collections and were compared using Kolmogrov-Smirnov, Chi-square, and Fisher's exact tests. Both museum collections show a bias toward more elaborately decorated pieces, but with varying side effects on other attributes of analytical interest.

Spindle Whorls

Material culture studies demonstrate how objects may act to communicate information regarding social identity. In this study we consider ethnohistorical, ethnographic, and archaeological evidence for Postclassic spinning and weaving as symbols relating to female ideology in ancient Mexico. We then relate a contextual interpretation of texts and images to contemporary symbolism, particularly associated with members of the female earth/fertility deity complex depicted and described in precolumbian and early colonial pictorial manuscripts. For our case study we analyze decorative imagery found on baked-clay spindle whorls from Postclassic Cholula, Mexico. This collection is representative of an iconographic system relating to female ideology. Whorls, as well as other spinning and weaving tools, paralleled male-oriented weapons to create a symbolic equivalence or, as we argue, a usurpation of the male symbols within a female worldview as a form of resistance to male domination. We conclude that the symbolic system used on spindle whorls and in other aspects of female practice created a communication network understood by Postclassic women.

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Culture and the plasticity of perception

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
