A Bayesian AMS C chronology of the Classic Maya Center of Uxbenká, Belize

Archaeologists require precise chronologies of cultural change to understand the nature and timing, and causes and effects, of ecological and social transformations. The Uxbenká Archaeological Project (UAP) has made chronology building a main goal, employing epigraphic data, artifact seriation, and high-precision AMS ¹⁴C dating. With more than 60 ¹⁴C dates with measurement errors below ±25 ¹⁴C yr, primarily on single charcoal specimens, Uxbenká may be the most intensively dated Classic Period site in the tropical Maya Lowlands. Here we take the next step, combining this rich chronometric dataset with associated stratigraphic information in OxCal's Bayesian framework to generate a high-resolution chronology of Uxbenká's early development and expansion in southern Belize. We show how archaeologists may take advantage of complex architectural stratigraphy to constrain broad calibrated ranges during the Classic Period, and to estimate dates for observed construction events that can not be directly dated (e.g., clearing/leveling plazas, laying plaster floors, renovating/rebuilding structural elements). Our analysis confirms the antiquity of the ceremonial Stela Plaza (Group A), where first construction is estimated between 60 cal BC and cal AD 220 and is associated with a Pre-Classic structure obscured by later construction and reorientation of the group to a N-S alignment ca. AD 150–310. The analysis also indicates initial leveling and construction at plaza Group B from cal AD 60–310 and Group D from cal AD 20–240, both earlier than previously assumed. Though Late Classic contexts are not as well represented by direct dates, architectural modifications are documented at all three plaza groups after AD 550, including the extensive plastering, laying paving stones, and construction of facades on existing structures. The resulting chronology revises our previous thinking on the mode of settlement and development of Classic Maya society at Uxbenká and indicates specific areas of investigation to elucidate events in the Late and Terminal Classic at the site, including political and social fragmentation and the abandonment of the urban core late in the Classic Period.     

Securing the “Interests” of the South: John Mitchel,A.G. Magrath,and the Reopening of the Transatlantic Slave Trade

Traditionally scholars have downplayed the importance of southern calls to reopen the transatlantic slave trade in the 1850s. Those who have paid serious attention to this effort see it as another endeavor by aristocratic planters to enshrine their social, economic, and political power in the antebellum South. The advocates were, as one puts it, “no champions of the common white man.” Two Irish-American leaders who supported the reopening, John Mitchel and Andrew Gordon Magrath, complicate this view of the attempt as just a planters’ plot. Their actions and opinions indicate that some proponents did see importing African slaves as something that would benefit all whites and not just the elite, and, as a result, protect the overall “interests” of the South. Mitchel and Magrath's support of Ireland and Irish immigrants and their opposition to British power influenced their positions on the matter.     

The Politics of Ego: Senatorial Front Office Presentation of Self

Many scholars have studied elected officials’ presentation of self, typically through examination of behavior in their districts, speeches, and Web sites. In this article, the authors examine a little-studied but telling element of U.S. senators’ presentation of self—the images they display to constituents and others visiting their offices in Washington, DC. Drawing on original data, we analyze both the total amount of items displayed as well as the number that focus on the senators themselves, and find that having run for president, being a Republican, and representing a state closer to Washington, DC, all predict a senator having more self-centered front-office décor, while having served more years in the chamber and hailing from a state closer to the nation's capital are associated with greater sheer number of items displayed in a senator's front office. This research demonstrates that political ambition, geography, and partisan affiliation are all related to senatorial ego. Studying senators’ presentation of self via their office walls offers important insight into the ways that elected officials view themselves and present themselves to a variety of audiences, thereby offering a glimpse of the ever-elusive link between the represented and the representative.     

How to Make an Unfired Clay Cooking Pot: Understanding the Technological Choices Made by Arctic Potters

Between about 500 a.d. and the late nineteenth century, clay cooking pots associated with the Thule culture were produced in the Arctic region. Ethnographic and archaeological records indicate that these vessels were typically underfired (often even unfired), highly porous, and easily broken. Despite these characteristics, the evidence indicates that they were used to heat water over open fires. In this paper, we examine how Arctic potters were able to produce unsintered vessels capable of holding liquids without disintegrating. We conclude that the application of seal oil and seal blood to the pot’s surface was the key to their success.

The Bush administration and Asia Pacific multilateralism: unrequited love?

This article challenges the presumed multilateral aversion of the George W. Bush administration. It argues that, at least in its approach toward the Asia-Pacific, this administration has been a more active and stimulatory advocate of multilateral approaches than is commonly acknowledged. The article begins by documenting the Bush administration's multilateral activism in the Asia-Pacific and examines those factors which appear to have contributed towards it. It then goes on to demonstrate, however, that Bush's at times unexpected enthusiasm for multilateral approaches has encountered a high degree of regional reticence. For a part of the world that has been affording an increased prominence to multilateral institutions and activities, this finding is initially both surprising and significant. The article concludes by seeking to account for this apparent anomaly and by considering its possible implications for the emerging regional architecture.     

Pre-pottery farmers on the Pacific coast of southern Mexico

Large island-like shell mounds along the southern coast of Mexico are the earliest known archaeological sites on the Pacific margin of Mesoamerica. These aceramic deposits date to between 7500 and 3800 cal BP and have been interpreted as locations where foragers, living elsewhere seasonally on the coastal plain, harvested shellfish and other estuarine resources. Based on an accumulation of paleoecological data from elsewhere in the lowland Neotropics of Mesoamerica, southern Central America and South America we pose and provide a first test of an alternative subsistence model: that the Archaic Period populations in this area were slash and burn farmers. Burned maize phytoliths first appear in these sedimentary records at 6500 cal BP in association with macroscopic charcoal and forest disturbance plant taxa. Periodic burning and forest disturbance, consistent with farming activities, are also evident in the macroscopic charcoal record between 6500 and 4700 cal BP. Pollen, phytolith and charcoal records all point to sustained burning, forest disturbance and the cultivation of maize between 4700 and 3800 cal BP. These data suggest that people were slash and burn farming during the Archaic Period prior to the adoption of pottery and the proliferation of Early Formative Period villages and full-fledged agriculture based on near or total reliance on crop plants after ∼3800 cal BP.     

Urban research and child-friendly cities: a new Australian outline

Recent public debates about Australia's children and young people have begun to acknowledge the direct impact of urban development on their health and well-being. This paper reviews a broad range of trans-disciplinary literature addressing child-friendliness in contemporary Australian cities, drawing particular attention to the fact that even some of the most recognised texts on children and young people in Australia still make few references in their analysis to the issue of place and neighbourhood. More specifically, the paper points to two particular research challenges confronting the ongoing study of young people's well-being in urban areas, including (a) the need for a more thorough analysis, both conceptual and applied, about how children and young people's well-being is affected by different urban forms and by the social and ecological variations that occur throughout cities; and (b) the focus on younger children needs to be complemented by a focus on adolescents and young adults who in turn need to be actively involved in confronting these challenges.
