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.     

Sociopolitical network interactions: A case study of the Classic Maya

The organization of Classic Maya society emerged from diverse and overlapping social interactions which shaped a dynamic political landscape. Vying for power, elites legitimized their status by claiming ancestry from various supernaturals and engaged in conspicuous displays of competition, warfare, and ritual practice which were often recorded on stone monuments. By examining the inscribed relationships between Maya centers, we chart organizational changes in sociopolitical networks throughout the Classic period. Methods derived from social network analysis are used to examine temporal changes in the distribution and centralization of political power through different network interactions. We examine the intersection of antagonistic, diplomatic, subordinate, and kinship relationships and discuss how these overlapping networks contributed to dynamic changes in the Classic period. This case study demonstrates how current network analysis techniques can contribute to archaeological studies of the scalar dynamics and organizational changes of past social and political systems.     

ARE LOCAL MILIEUS THE KEY TO INNOVATION PERFORMANCE?*

ABSTRACT This study investigates how local milieus foster innovation success in firms. We complement the common practice of linking firm performance indicators to regional characteristics with survey evidence on the perceived importance of locational factors. While the former approach assumes that location characteristics affect all firms in the same way, the survey allows us to model how firms judge the attractiveness of locations using a heterogeneous set of criteria. It turns out that the availability of highly skilled labor and the proximity to suppliers matter for firms' innovation performance. Interestingly, location factors obtained from the survey provide a more accurate explanation of how local milieus facilitate innovation.     

Population Synthesis: Comparing the Major Techniques Using a Small, Complete Population of Firms

Recently, disaggregate modeling efforts that rely on microdata have received wide attention by scholars and practitioners. Synthetic population techniques have been devised and are used as a viable alternative to the collection of microdata that normally are inaccessible because of confidentiality concerns or incomplete because of high acquisition costs. The two most widely discussed synthetic techniques are the synthetic reconstruction method (IPFSR), which makes use of iterative proportional fitting (IPF) techniques, and the combinatorial optimization (CO) method. Both methods are described in this article and then evaluated in terms of their ability to recreate a known population of firms, using limited data extracted from the parent population of the firms. Testing a synthetic population against a known population is seldom done, because obtaining an entire population usually is too difficult. The case presented here uses a small, complete population of firms for the City of Hamilton, Ontario, for the year 1990; firm attributes compiled are number of employees, 3-digit standard industrial classification, and geographic location. Results are summarized for experiments based upon various combinations of sample size and tabulation detail designed to maximize the accuracy of resulting synthetic populations while holding input data costs to a minimum. The output from both methods indicates that increases in sample size and tabulation detail result in higher quality synthetic populations, although the quality of the generated population is more sensitive to increases in tabular detail. Finally, most tests conducted with the created synthetic populations suggest that the CO method is superior to the IPFSR method.     

Sarah the Princess: Tracing the Hellenistic Afterlife of a Pentateuchal Female Figure

This article analyses Philo of Alexandria’s and Josephus Flavius’s interpretations of Sarah from the viewpoint of social and political power attached to her. Both ascribe the figure royal attributes (i.e. she is depicted as a princess or queen) and other features that promote her as a virtuous model and an individual of public standing. A variety of emphases, philological and philosophical interpretations alike, jointly serve to construct Sarah’s exemplarity. The aim of this article is to demonstrate that different dimensions of biblical female figures may be revealed when their role as spouses and mothers is not taken as the starting point of analysis in studies concerning the reception history of biblical women.
