The Evolution of Migration: the Case of Lapita in the Southwest Pacific

Migrations have occurred across the history of the genus Homo and while the movement of pre-modern humans over the globe is typically understood in terms of shifting resource distributions and climate change, that is in ecological terms, the movement of anatomically modern, and specifically Holocene, populations is often explained by human desire to discover new lands, escape despotic leaders, forge trade relationships and other culture-specific intentions. This is a problematic approach to the archaeological and behavioural explanation of human migration. Here an evolutionary and ecological framework is developed to explain various movement behaviours and this framework is applied to the movement of human groups from the inter-visible islands around New Guinea to the widely dispersed archipelagos of the southwest Pacific about 1000 BC. Labelled the Lapita Migration, this movement is explained as a selection-driven range expansion. The development of evolutionary and ecological theory to explain human movement facilitates empirical testing of alternative hypotheses and links different histories of human movement through shared explanatory mechanisms.     

DECONSTRUCTING HISTORICIST TIME,OR TIME'S SCRIBE

This article investigates the enduring chronopolitics of Historicism. To do so, I work through two dominant understandings of Historicism: the view that “historicism” is a means to account for the historian's own standpoint or historical situation as the place from which they take up and interpret the past, which I call Historicism A, and the separate (though now more popular) understanding of “historicism” that is derived from Karl Popper's The Poverty of Historicism, which I call Historicism B. I am less interested in what draws these varying definitions of Historicism apart and instead investigate a point of intersection in their understanding of time and temporality. Both strains serve politics via a concept of time as a neutral, uniform, and apolitical scale upon which any political or ideological agenda is enacted. Time here serves as the basis for historical explanation, but its neutrality, homogeneity, and extra-historicality are a trick. I employ Gérard Genette's analytic of the palimpsest, with the help of Nancy Partner, to expose the ways that Historicism allows the past to be rewritten and overwritten to political and ideological ends that the temporal construct conceals. This then enables me to work through the politics of Historicism and ultimately deconstruct Historicist time, demonstrating how the universal or eternal claims of Enlightenment or pre-Historicist thought are actually maintained in Historicism as the mechanism to advance political and ideological positions under the cloak of neutrality. In what follows, I make the temporal mechanism of Historicism explicit in order to expose the ethical failings that this mechanism conceals.

Application of X-ray fluorescence imaging to ceramics from the American Southwest

We have used synchrotron-based X-ray fluorescence imaging (XRFI) to examine sherds of painted ceramics from prehistoric cultures of the American Southwest. These sherds are very well suited to XRFI analysis. Paints can generally be detected and distinguished by the fluorescence intensities of their constituent elements. Spatial maps of element distributions yield the spatial distribution of pigments. Pigments can be distinguished that are (or have become) visually similar; layers that have been obscured by overpainting can be examined; and pigment residues can be distinguished from surface contaminants deposited after painting and firing. As a result, XRFI allows the painted motifs to be clarified and hidden features to be revealed. Furthermore, the very rapid scanning and high sensitivity elemental detection possible with synchrotron-based XRFI facilitate measurements on large collections of sherds, allowing an integrative rather than anecdotal analysis.     

A comparison of multiple proxy data sets for paleoenvironmental conditions as derived from freshwater bivalve (Unionid) shell

Freshwater mussel shells from Middle and Late Holocene strata at an archaeological site in Mississippi, U.S.A., are examined for morphological and chemical differences that could be related to changing paleoenvironmental conditions. Although significant differences are noted, the different data sets provide contradictory or unclear results, suggesting that reliance upon single data sets is an unwarranted practice.     

From Body Reform to Reforming the Body Politic: Transcendentalism and the Militant Antislavery Career of Thomas Wentworth Higginson

Second‐generation Transcendentalist minister Thomas Wentworth Higginson played a leading role in the latter stages of the struggle against slavery. A principal member of the Boston Vigilance Committee, which resisted attempts to capture fugitive slaves, Higginson also provided support for John Brown’s assault at Harpers Ferry and served as colonel of the Union’s first regiment of African Americans during the Civil War. Building on recent scholarship that portrays Transcendentalists as sympathetic to the antislavery cause, this essay argues that Higginson’s militant approach to abolitionism drew directly on key components of Transcendentalism. It thereby offers a fresh interpretation of the emergence of antislavery violence in the 1850s, while underscoring a fundamental connection between the philosophy of Transcendentalism and radical abolitionism.
