Role playing: a feminist-geopolitical analysis of the everyday workings of the Mexican state

Participatory methods are increasingly important to geographical research of ‘the everyday,’ yet their viability as a means to understand on-the-ground geopolitical processes has been less explored. This article contributes to the growing body of literature on participatory research in geography and feminist geopolitics by arguing for the use of a specific participatory tool – role play. We present an example of our employment of the technique in a case study on using the method during research with Central American immigrants living in the Mexico–Guatemala border city of Tapachula, Mexico. In doing so, we provide an in-depth examination of the implementation of role play, demonstrating its usefulness in revealing immigrant women's daily experiences with low- to mid-level state actors as they seek to avail themselves of their rights. We conclude that role play is particularly well suited to revealing these experiences due to its encouragement of creativity, embodiment through performance and facilitation of in-depth discussion of difficult subject matter.     

Being Toured While Digging Tourism: Excavating the Familiar at Chicago’s 1893 World’s Columbian Exposition

Chicago’s Jackson Park witnessed intense and sustained tourism during the 1893 World’s Columbian Exposition. Recent archaeological survey and excavation produced information about the tourist experience of the Fair in a somewhat familiar artifactural form. The dig drew local tourists whose appetites for the Exposition were whetted by a bestselling book. At the heart of these multiple touristic consumptions in, and of, Jackson Park lies the central issue—the way that tourists create themselves as modern subjects through the practice of tourism and how this process can be both helped and hindered by the presence of familiar objects.     

The Significance of Social Gestures and Technologies of Embellishment in Paleolithic Portable Art

This paper analyzes the gestures and technologies used to make Paleolithic portable art. Contextualized within the theoretical schools of the anthropology of technology and using the chaîne opératoire methodology, the approach advanced here quantifies the relationships between technology, society, and aesthetics in the production of Paleolithic art. Focusing on Pavlovian art, dating to between 28,000 and 24,000 radiocarbon years BP, this paper assesses the suite of art production technologies, particularly those used when modifying and decorating ivory, and traces the relationship between decorative techniques and other characteristics of art. These analyses offer insight into Pavlovian art traditions and the emergence of innovative techniques in Paleolithic societies.     

New Methods of Census Record Linking

The Minnesota Population Center (MPC) has released linked datasets through its NAPP and IPUMS projects, making them readily accessible to researchers. Prior to the availability of complete count census microdata from the MPC, researchers applied various forms of record-linking software. This essay describes the techniques used in the MPC's linking program and briefly compares this technique with those used by other researchers. The key feature of the MPC linking method is the construction of cumulative name similarity scores, based on approximately 2.5 billion record comparisons; we also use support vector mechanics to classify potential links. This article explains modifications made for the final linked datasets and includes a discussion of the role of weighting variables when using linked data.     

An archaeologically validated protocol for computing obsidian hydration rates from laboratory data

This paper reports the computation of hydration rate for Topaz Mountain obsidian from laboratory data, and a comparison with archaeological data from a well-dated site, Camels Back Cave, in western Utah. Topaz Mountain obsidian is found to be slow-hydrating, with a rate of 0.071 ± 0.021 μ/yr^½ at an effective hydration temperature of 16.01 °C. This rate agrees with a rate developed from archaeological data from Camels Back Cave within ∼6%. Activation energy of Topaz Mountain obsidian is 10370 ± 544 K, and its diffusion constant is (1.87 ± 9.13) × 10¹³ μ²/yr, both of which are independent of temperature. Its intra-source variability in hydration rate is very low (CV < 0.01), implying a low variability in intrinsic water. We present a model of chemical erosion which shows why earlier laboratory-determined rates were incorrect, and discuss the implications of our findings on the determination of experimentally derived rates in obsidian hydration dating.     

Can salmonids (Oncorhynchus spp.) be identified to species using vertebral morphometrics?

Remains of anadromous Pacific salmon and trout (genus Oncorhynchus) are common in archaeological sites from California to Alaska; however, morphological similarity generally precludes species identification, limiting the range of questions that salmonid remains can address in relation to past human use and ongoing efforts in conservation biology. We developed a relatively simple, rapid, and non-destructive way to classify salmon and trout vertebrae from archaeological contexts to species using length, height and the ratio of length to height. Modern reference material was obtained from all seven anadromous Oncorhynchus species native to the west coast of North America. A minimum of ten adult Chinook (Oncorhynchus tshawytscha), chum (Oncorhynchus keta), coho (Oncorhynchus kisutch), pink (Oncorhynchus gorbuscha), and sockeye salmon (Oncorhynchus nerka) and cutthroat (Oncorhynchus clarki clarki) and steelhead trout (Oncorhynchus mykiss) were skeletonized and vertebra length and height were measured. Morphometric analyses compared species classification success based on Linear Discriminant Analysis (LDA), Classification and Regression Trees (CART), and randomForest, with CART performing the best. Classification analyses used all seven species individually, but because of considerable overlap among several species we also conducted analyses on four species groupings. We assigned Chinook salmon and cutthroat to their own groups based on their dissimilarities from each other and the other species. The remaining species were divided into two group complexes (a) chum, coho, and steelhead; and (b) pink and sockeye. When we grouped species according to similar morphology, CART overall success rates increased, ranging from 92 to 100%. Individual species with the highest successful classification rates using CART were Chinook salmon and cutthroat, from 92 to 100%, respectively. We applied our classification to an assemblage of ancient (1000–3000 year old) salmonid vertebrae from the Swiftwater Rockshelters excavations on the upper Wenatchee River in Washington State, U.S.A.     

Populism and nationalism

Few social science categories have been more heatedly contested in recent years than ‘populism’. One focus of debate concerns the relation between populism and nationalism. Criticising the tendency to conflate populism and nationalism, De Cleen and Stavrakakis argue for a sharp conceptual distinction between the two. They situate populist discourse on a vertical, and nationalist discourse on a horizontal axis. I argue that this strict conceptual separation cannot capture the productive ambiguity of populist appeals to ‘the people’, evoking at once plebs, sovereign demos and bounded community. The frame of reference for populist discourse is most fruitfully understood as a two‐dimensional space, at once a space of inequality and a space of difference. Vertical opposition to those on top (and often those on the bottom) and horizontal opposition to those outside are tightly interwoven, generally in such a way that economic, political and cultural elites are represented as being ‘outside’ as well as ‘on top’. The ambiguity and two‐dimensionality of appeals to ‘the people’ do not result from the conflation of populism and nationalism; they are a constitutive feature of populism itself, a practical resource that can be exploited in constructing political identities and defining lines of political opposition and conflict.
