Reconstructing patterns of systemic stress in a Jomon period subadult using incremental microstructures of enamel

This study reconstructs systemic stress patterning using incremental microstructures of enamel in a subadult from the Yoshigo cemetery (3200 through 2800 BP), Aichi Prefecture, Japan, with the goal of providing an improved methodological and theoretical framework for interpreting systemic stress among Jomon people. High resolution impressions and replicas were collected for each anterior maxillary tooth. Each replica was studied under 50, 100, or 200× magnification on a measuring microscope. Perikymata spacing and enamel surface profiles were recorded using specialized software. Linear enamel hypoplasia (LEH) defects were identified as accentuated spacing in perikymata combined with a depression in the enamel surface. Each defect was placed within a chronological sequence based on decile location. Stress duration was estimated by counting the perikymata in the occlusal wall of each defect and multiplying that value by the modal periodicity for striae formation. Percentage of enamel growth disruption was estimated by dividing the number of perikymata within the occlusal wall of each matched defect by the total number of perikymata within the imbricational enamel. Eight LEH defects were chronologically matched. Chronology of LEH defects ranged between 1.2 through 3.5 years. Number of perikymata located within the occlusal wall of each defect ranged from one through 20. Estimated durations of stress ranged from 12 through 129.6 days. These durations overlapped with Neandertals, though Point Hope foragers had greater durations of stress with no overlap in interquartile ranges. Disrupted enamel growth ranged from 8.1% in the maxillary left canine to 50.7% in the maxillary right central incisor.     

Pottery production and distribution in prehistoric Bronze Age Cyprus. An application of pXRF analysis

Portable X-ray Fluorescence (pXRF) analysis of over 400 samples of Early and Middle Bronze Age Cypriot pottery from four widely separated sites identifies both local and non-local products at each. A series of analyses of sub-sets of the data highlights differences in the clays used at each site and for some distinctive types and wares. When assessed in the context of general typological, technological and stylistic factors these variations provide the basis for considering patterns of local production and inter-regional relationships across the island. Although the great majority of pots were locally made, particular wares and shapes were brought in from elsewhere. For some sites finer, more highly decorated vessels are mostly imports, but at others both simpler and more complex vessels were made of the same local clays. While small juglets or flasks may have been containers for transporting small quantities of rare substances, larger vessels are likely to have held less precious material. Open vessels, especially small bowls – some of which are plain, utilitarian items – represent another aspect of social behaviour and inter-regional relationships.     

Excavating Zarathustra: Ernst Herzfeld's Archaeological History of Iran

This article analyzes the work of the German archaeologist Ernst Herzfeld (1879–1948) and its influence on the writing of Iranian national history in the 1920s and 1930s. Herzfeld's life and work illuminates the relationship between Germany and Iran and between orientalist scholarship and nationalist history in the first half of the twentieth century. Through the method of what he called “archaeological history,” Herzfeld wrote an interdisciplinary history of Iran and its Aryan foundations that contested the assumptions of decades of European orientalist scholarship.     

Between crime and colony: interrogating (im)mobilities aboard the convict ship

Recent literature in carceral geography has attended to the importance of mobilities in interrogating the experience and control of spaces of imprisonment, detention and confinement. Scholars have explored the paradoxical nature of incarcerated experience as individuals oscillate between moments of fixity and motion as they are transported to/from carceral environments. This paper draws upon the convict ship – an example yet to gain attention within these emerging discussions – which is both an exemplar of this paradox and a lens through which to complicate understandings of carceral (im)mobilities. The ship is a space of macro-movement from point A to B, whilst simultaneously a site of apparent confinement for those aboard who are unable to move beyond its physical parameters. Yet, we contend that all manner of mobilities permeate the internal space of the ship. Accordingly, we challenge the binary thinking that separates moments of fixity from motion and explore the constituent parts that shape movement. In paying attention to movements in motion on the ship, we argue that studies of carceral mobility must attend to both methods of moving in the space between points A and B; as micro, embodied and intimate (im)mobilities are also played out within large-scale regimes of movement.     

Making waves: The Royal Navy's management of invention and innovation in steam shipping, 1815–1832 1

Abstract

This paper explores the sources of invention and innovation in steam shipping, the distribution of funding and risk between the state and the private sector, and the Royal Navy's management of innovation, during the experimental period of steam power's adoption at sea. It identifies two intersecting channels through which steam‐related innovations reached the Royal Navy. First, “packages” of innovations were embedded in the marine engines that were commissioned by the Navy from private engine‐making firms. Secondly, the Navy was spontaneously offered a gamut of ideas and inventions, which varied enormously both in potential importance and in degree of development. Although the mechanisms for dealing with these two channels were different, the end result was much the same ‐ in minimizing both the expense and the risk borne by the public sector. It was principally the private sector that was funding scientific and technological development in this sphere. Recognizing its own lack of expertise and consequent hazard, the Navy Board was developing a systematic yet flexible method of assessing steam‐related inventions ‐ which appears to have served it well.     

“Happy Birthday” and Other Awkward Sentiments: Nixon’s Social Interactions as Part of Congressional Relationship Building

Abstract

Presidential persuasion is one of the most investigated soft-power interactions between the president and members of Congress. However, presidents are often as interested in long-term relationship building strategies that do not include an immediate favor request. This project analyzes those relationship building strategies between President Richard Nixon and members of Congress. One hundred sixty-three conversations between Nixon and members of Congress have been transcribed and analyzed. As part of an overall goal of building and maintaining interbranch relationships with members of Congress, Nixon utilized a mixture of three social goal approaches: social-support contacts, information gathering and exchange contacts, and offering material benefits.
