Interrogating Power: Engaged Energy Anthropology

Human-induced global threats are compelling many anthropologists to rethink roles, methods, and paradigms and engage in public debate and action on energy policies, extraction processes, commodity chains, and consumption. Laura Nader's Energy Reader embodies her decades-long engagement as a catalyst for public debate on U.S. energy issues. Tanja Winther's Impact of Electricity exemplifies ethnography informing development practice. Strauss and colleagues’ Cultures of Energy reflects diverse approaches seeking to build cultural understandings to inform energy choices. There remains a need for collaboration with anthropologists embedded in energy-related agencies—positioned where they can leverage anthropological knowledge to push policy envelopes.     

Hayonim Cave: a TL-based chronology for this Levantine Mousterian sequence

The thermoluminescence dating method was applied to 77 heated flints from the Mousterian layers of Hayonim Cave in order to provide a precise TL-based chronology for this important Levantine sequence. A detailed dosimetric study was performed by using 76 dosimeter capsules and revealed strong spatial dose-rate variations. In parallel, Fourier transform infrared spectrometry enabled the identification of various mineral assemblages in the sediments of the cave and to localize the boundaries of these assemblages. By comparing these two data sets, it is shown that low dose-rate values (∼500 μGy/a) are systematically recorded in areas where the calcite-dahllite (CD) assemblage is preserved, whereas higher values (up to 1300 μGy/a) are associated with the leucophosphite, montgomeryite, variscite and siliceous aggregates (LMVS) assemblage. The dosimetric and mineralogical information was combined in order to assess, where possible, the dose-rate experienced by each flint during its burial. Some of the flint samples analyzed were too close to mineral assemblage boundaries and were therefore discarded. This rigorous selection led to TL ages ranging from 230 to 140 ka for the lower part of the Mousterian sequence (layers F and Lower E), which contains lithic industries characterized by blade production using the laminar method.     

New Perspectives in Mississippian Archaeology

In recent years the pace of research on the late prehistoric Mississippian societies of eastern North America has accelerated. New data, methods, and theoretical goals are changing perspectives in Mississippian archaeology. Regional overviews and site syntheses provide unprecedented insights into the Mississippian phenomenon at local, regional, and continental scales. Traditional culture history, processualism, historical processualism, iconography, and neo-Darwinian archaeology are active theoretical orientations. Important research focuses on variability in Mississippian sociopolitical formations over time, organizational diversity among contemporaneous societies, and sources of political power. The new historicism and iconography place agency, identity, origins, factionalism, ideology, and meaning at the center of culture change, while many processualists continue to focus on developmental histories, economy, and control of material resources. Advances in physical and chemical analyses and the availability of remote sensing techniques are changing how Mississippian archaeology is conducted and expanding the kinds of data that are recovered. These diverse interests, methods, and goals have created considerable eclecticism in Mississippian archaeology.     

The Case of William Dick: Ransom County, North Dakota

In May 2009, a decision of the United States Supreme Court with North Dakota roots turned fifty years old. A case unique in the annals of the law, Dick v. New York Life Insurance Company ¹ still fascinates lawyers today. Factually, the case presented a strange question: could an experienced hunter accidentally shoot himself not once, but twice? Some of North Dakota's finest lawyers, including Philip Vogel, Donald Holand, and Norman Tenneson, aimed to get to the bottom of that matter. The judges were equally impressive: Judge Ronald Davies of the federal district court; Judge John Sanborn of the U.S. Court of Appeals for the Eighth Circuit; and Chief Justice Earl Warren and Justice Felix Frankfurter. Finally, as a matter of Supreme Court jurisprudence, Dick may have been the last time the High Court granted a petition for certiorari in a case that turned almost exclusively on questions of fact. In honor of its golden anniversary, this article recounts the captivating story of Dick v. New York Life.     

International Environmental Regimes: Legalisation,Flexibility and Effectiveness

In one of the first quantitative designs, we explore the impact of both legalisation and flexibility on regime effectiveness, using data on international environmental institutions. One of the main implications is that ‘precision’ is an important determinant of regime performance. If the rule and norm system is well defined, well understood and clear, then a regime tends to be more effective in addressing an environmental problem. We do not find evidence, however, that ‘hard law’ is more effective than ‘soft law’ or that delegation mechanisms may be relevant. Second, flexibility in the regime structure increases regime performance – regular instead of subsidiary bodies enhance flexibility and thus have a positive effect on a regime's environmental problem management. Flexibility in states' agenda setting power, membership and decision making do not seem to have a crucial influence, though.     

Simulation of adsorption of gold nanoparticles carried by gas ascending from the Earth’s interior in alluvial cover of the middle–lower reaches of the Yangtze River

The adsorption onto other minerals of charged gold nanoparticles, carried by gas ascending from the Earth’s interior, is an important component of their transport and deposition in surficial cover such as alluvial, aeolian, and glacial sediments. To simulate the adsorption of these particles, an experiment was conducted in which a flow of air that contained gold nanoparticles was passed upward through a sample of alluvium from the middle–lower reaches of the Yangtze River. These experiments showed that gold nanoparticles are adsorbed on kaolinite, halloysite, goethite, and hematite in the alluvial cover. Both the gold nanoparticles and minerals (i.e., kaolinite, halloysite, goethite, and hematite) carry surface charges that provide them with excellent adsorption properties. This study showed that the specific mineral composition of surficial alluvial cover affects the concentration of gold nanoparticles in the ascending gas. This phenomenon may plausibly be used in exploration for concealed gold, copper–gold, and silver–gold deposits in areas of thick alluvial cover. Geofluids (2010) 10 , 438–446     

THE USE OF OXYGEN ISOTOPES IN SHEEP MOLARS TO INVESTIGATE PAST HERDING PRACTICES AT THE NEOLITHIC SETTLEMENT OF ÇATALHÖYÜK,CENTRAL ANATOLIA

This paper presents a pilot study designed to test the use of oxygen isotopes for investigating aspects of early herding practices in the Neolithic of western Asia, using the site of Çatalhöyük in central Anatolia as a case study. Time‐sequenced δ¹⁸O values in dental enamel of archaeological sheep are assessed for post‐depositional diagenetic effects and compared with seasonal δ¹⁸O meteoric water values in the region today. The evidence is used to indicate the environmental conditions in which individual sheep spent their first year, enabling management of breeding and birthing seasons, and movement to seasonal pastures, to be investigated.
