What is this bird? The quest to identify parrot remains from the Heyward-Washington House,Charleston, South Carolina

ABSTRACT

Excavations in the 1970s at the ca. 1772 Heyward-Washington House in Charleston, South Carolina, produced a rich and diverse archaeological assemblage spanning the eighteenth and nineteenth centuries. Among the vertebrate remains are four bones from a large member of the parrot family. We now believe the bird was a blue-fronted or turquoise-fronted amazon parrot (Psittacidae: Amazona aestiva), an animal originating in South America. Over the decades, we have studied the zooarchaeological signature of social identity in Charleston, the evolving urban environment, and the vast trade networks of the colonial port city, all of which are embodied in the remains of this single bird. The parrot leads to a discussion of social roles of captive birds in early Charleston, the eclectic interests of city residents, and the city’s global trade networks.     

‘There Is Graite Odds between A Mans being At Home And A Broad’: Deborah Read Franklin and the Eighteenth‐Century Home

From 1764 to her death in 1774, Deborah Franklin lived in ‘their’ new house without husband Benjamin. The correspondence between them reveals several ambiguously gendered constructions of that house – ideologically, materially, and architecturally. Deborah was ‘homeless’ legally and conceptually. Her household variously consisted of her mother, her adopted son, her daughter, relatives, guests, boarders and servants – she permanently assumed the role of head of the household. His household consisted of his landlady, Widow Margaret Stevenson, and her daughter Polly – he could not assume his role as head of household. Moreover, as Deborah wrote to her husband about turning the house into a fortress during a raid on it during Stamp Act crisis, he wrote to her about the household goods; as she talked about politics, he discussed familial matters. Their permeable, even ambiguous, masculine and feminine roles reconstructed the meaning – and thereby symbolised the gendered complexity – of the early American white middling and elite eighteenth‐century home.     

Microfinance among the Maya: Tracking the Progress of Borrowers

Microfinance has become an increasingly widespread tool for fostering economic growth among the poor in developing countries. This study tracks the progress of 239 borrowers in a Guatemalan microfinance institution from 1994 to 1999. Results from the study show that rapid gains in employment within the sample enterprises after initial credit access were followed by a protracted period of stagnation in employment growth. Other results highlight gender differences in response to credit access, showing — surprisingly — that the long–run growth in hired labour for female entrepreneurs was slightly greater than that for male entrepreneurs.     

Postmaterial Values and Age: The Case of Australia

Inglehart's thesis of value change is one of the most widely discussed accounts of social and political change in advanced Western nations. This article offers a critique of Inglehart's thesis and a clarification of the Australian case. While critics of Inglehart have attacked the validity of his values measures, or sought to improve them, we use Inglehart's own values index to show that even if--as Inglehart claims--his measures are valid, the age/values predictions do not hold as the theory suggests in Australia. In a recent article, Inglehart and Abramson (1999, 673) cite Australia among a group of '28 high-income' countries that exhibit 'stronger relationships between values and age' than found in the United States. We dispute Inglehart and Abramson's findings in relation to Australia. We show that the relationship between age and values in Australia, like the United States, is very weak, highlight the problematic nature of assuming a linear relationship between age and values without evidence, and discover a new non-linear relationship between values and birth cohorts in Australia that has implications for the study of values research internationally.     

Continuous Characterization of the Planform Geometry and Curvature of Meandering Rivers

The complex feedback between process and form that governs planform migration of meandering rivers is still incompletely understood. Current theoretical models aimed at predicting planform migration relate the rate of meander migration at a particular location to the channel curvature at and upstream of that location. However, these models are still incapable of reproducing complex forms of bend development, such as compound loops. Evaluation of such models requires a representation of planform curvature better than that provided by traditional methods where the curvature is calculated from directional change between the successive digitized points—an approach that provides a discrete representation of curvature dependent on the density of the digitized points used to characterize the channel planform. This article presents and evaluates a methodology that provides a continuous functional representation of the planform geometry and curvature of meandering rivers. The method involves the fitting of splines, specifically parametric cubic splines (PCSs), to discrete digitization data of the channel centerline (CL) and the arc-length parameterization of the resulting composite curve. The arc-length parameterized PCS-interpolated curve is then used to compute analytically the channel CL location and curvature for any value of the streamwise axis. Evaluation of the method involves examination of the effects of digitization interval size and digitization error on the characterization of the planform geometry and curvature using PCS fitting. The derivation of curvature values from continuous planform function for any location and any spatial interval overcomes the reliance either on average bend curvature values or on discrete curvature values based on digitized points.
