The Moorehead Phase Occupation at the Emerald Acropolis

The Emerald site, also known as the Emerald Acropolis, was an early Mississippian pilgrimage center key to Cahokia’s development. This paper presents the hitherto unpublished results of two archaeological projects conducted at the site, one led by Howard Winters and Stuart Struever in 1961 and the other by Robert Hall in 1964. These investigations produced the most comprehensive information on Emerald’s Moorehead phase (1200–1300 CE) occupation, during which two of its mounds were capped, a secondary mound was constructed on the central mound, and a mound-top structure was erected on this secondary mound. Similar activities took place throughout the region during the thirteenth century, a time marked by dramatic social, political, and religious change in Greater Cahokia. Based on these data, we argue that people returned to Emerald to memorialize or draw on the powers inherent there and thus reincorporate this place into the newly imagined thirteenth century Cahokian world.     

Teaching energy geography? It’s complicated

The premise of this essay is that energy geographies are complicated, and this in itself presents some pedagogical difficulties. As someone who wants students to critically examine and confront the complexity of energy systems, it can be frustrating when students react to demonstrate frustration, apathy, or even confusion. In what follows, I will lay out three complications of teaching energy geography: (1) empirical complexity, (2) confronting fossil fuel “embeddedness,” (3) the energy culture fallacy.     

The Use of Gasoline: Value, Oil, and the "American way of life"

Abstract:  While the critical literature has focused on the geography of oil production, the politics of "outrageous" gasoline prices in the United States provide a fertile path toward understanding the wider geography of petro-capitalism. Despite the deepening contradictions of US oil consumption, "pain at the pump" discourse projects a political sense of entitlement to low priced gasoline. I use a value-theoretical perspective to examine this politics as not only about the quantitative spectrum of price, but also the historical sedimentation of qualitative use-values inscribed in the commodity gasoline. Gasoline is analyzed both as a use-value among many within the postwar value of labor power and as a singular use-value fueling broader imaginaries of a national "American way of life." While use-value still represents an open site of cultural and political struggle infused within value itself, the case of gasoline illustrates how use-values are not automatically mobilized toward politically savory ends.     

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.     

The Initial Meeting of the WAC Ethics Committee

Audie was struck by how far many had come to attend the meeting at Stanford, making the time together all the more precious. He discusses the challenges of first, determining what WAC stands for by identifying core concepts and foundational principles, many of them embedded in existing WAC documents and, second, of where the organization should draw lines when faced with the contradictions that are a part of most ethical dilemmas. A Code of Ethics would not be expected to draw these lines, but to bring these conflicts and contradictions into sharper focus and provide a dialogue and forum for their discussion. One of the many things Audie contributed to the meeting was a discussion and definition of consultation with Indigenous peoples, based on his many years of experience. Another was helping us put our ideas in a visual form that enhanced our understanding.     

Extracting sovereignty: Capital, territory, and gold mining in Tanzania

In contemporary discussions of “resource nationalism,” sovereignty is often imagined as the exclusive control of national states over internal resources in opposition to external foreign capital. In this paper, we seek to draw attention to the specifically national territorial forms of sovereignty that - rather than hindering the flow of capital - become constitutive to the accumulation of resource wealth by states and capital alike. Drawing from political geographical theorizations of sovereignty, we argue that resource sovereignty cannot be territorially circumscribed within national space and institutionally circumscribed within the state apparatus. Rather, sovereignty must be understood in relational terms to take into account the global geography of non-state actors that shape access to and control over natural resources. Specifically, we engage national-scale state sovereignty over subterranean mineral resources in the form of legal property regimes and examine the mutually constitutive set of interdependencies between mining capital and landlord states in the accumulation of resource wealth. Using Tanzania as a case study, we argue that national-scale ownership of subterranean mineral resources has been critical to attracting global flows of mining capital from colonial to contemporary times. We first examine the history of the colonial state in Tanganyika to illustrate how land and mineral rights were adjudicated through the power of the colonial state with the hopes of attracting foreign capital investment in the mining sector. We then examine contemporary efforts on the part of the independent United Republic of Tanzania to again enact legislation meant to attract foreign mining companies - and the consequences for local populations living near sites of extraction.     

Human capital accumulation and long‐term income growth projections for European regions

We propose an econometric framework to construct projections for per capita income growth and human capital for European regions. Using Bayesian methods, our approach accounts for model uncertainty in terms of the choice of explanatory variables, the nature of spatial spillovers, as well as the potential endogeneity between output growth and human capital accumulation. This method allows us to assess the potential contribution of future educational attainment to economic growth and income convergence among European regions over the next decades. Our findings suggest that income convergence dynamics and human capital act as important drivers of income growth for the decades to come.
