Multiscalar Perspectives on Social Networks in the Late Prehispanic Southwest
2015
Analyzing historical trajectories of social interactions at varying scales can lead to complementary interpretations of relationships among archaeological settlements. We use social network analysis combined with geographic information systems at three spatial scales over time in the western U.S. Southwest to show how the same social processes affected network dynamics at each scale. The period we address, A.D. 1200–1450, was characterized by migration and demographic upheaval. The tumultuous late thirteenth-century interval was followed by population coalescence and the development of widespread religious movements in the fourteenth and fifteenth centuries. In the southern Southwest these processes resulted in a highly connected network that drew in members of different settlements within and between different valleys that had previously been distinct. In the northern Southwest networks were initially highly connected followed by a more fragmented social landscape. We examine how different network textures emerged at each scale through 50-year snapshots. The results demonstrate the usefulness of applying a multiscalar approach to complex historical trajectories and the potential for social network analysis as applied to archaeological data.
Ancient economies have been characterized by many researchers as localized, highly controlled by political actors, and static over long periods of time. In Mesoamerica, recent research has cast doubt on these views, with the recognition of early market place exchange, production by households for exchange, and the wide-ranging integration of communities into regional trade networks. Here, we expand onan earlier network analysis of obsidian assemblages from the Maya region during theClassic and Postclassic periods to incorporate data for all of Mesoamerica between 900BC and AD 1520. Using both visual graphical representations and formal network metrics, we find that the Mesoamerican economy was dynamic and generally not highly centralized over time. The topology of this interactive network underwent significant changes over time. In particular, trends towards decreasing network hierar-chy and size culminated in the highly commercialized “international” economy of LatePostclassic period as noted in previous studies. Based on this analysis, we make the case that the ancient Mesoamerican economy was neither predominantly top-down nor static, and so does not conform with oft-held presumptions regarding preindustrialeconomies.
Social Networks and Northern Iroquoian Confederacy Dynamics
American Antiquity, 2018
The Wendat (Huron) and Haudenosaunee (Iroquois) confederacies of northeastern North America are often presented as functionally equivalent political formations despite their having distinct cultural traits and unique geopolitical and developmental histories. In this article we employ social network analysis of collar decoration on ceramic vessels both to examine organizational differences in the social network that composed each group and to evaluate women’s participation in political activities as potters who produced and transmitted social and political signals. The concept of social capital and the dimensions along which it varies are employed to understand variability in network statistics and topologies. Our results indicate that the Wendat confederacy formed a “complete” network characterized by bonding ties of social capital, whereas the Haudenosaunee confederacy was a “coalitional” network characterized by bridging ties. The results suggest that women’s signaling networks were integral to how each confederacy functioned and the norms of reciprocity, trust, and information-sharing that defined each political formation.
In the proposed project I simultaneously and reflexively identify and characterize social boundaries in the archaeological record by examining material culture distributions in novel ways to re-assess the scale of the Verde Confederacy, a proposed regional-scale multi-settlement alliance in Late Prehistoric central Arizona. I focus on boundaries between entities larger than villages, but smaller than regions or culture areas. I propose three innovations to better accomplish these goals. First, unlike previous conceptualizations of social boundaries as monolithic, I argue that they are better conceived of as a heterogeneous, multi-faceted phenomenon. Second, I investigate social boundaries by examining multiple lines of evidence. Previous researchers have tended to focus on one category of data at the expense of others. Third, I associate boundaries with relational and categorical collective social identification. An alliance requires regular collective actions including communication and coordinated action between large groups. These actions are most likely to emerge among groups integrated by relational networks who share a high degree of categorical homogeneity. I propose a plain ware ceramic provenance model. Seven reference groups represent ceramic production in specific geographic areas. The reference groups are mineralogically and geochemically distinct, and can be visually differentiated. With this provenance model, I reconstruct the organization of utilitarian ceramic production and exchange, and argue that plain ware distribution is a proxy for networks of socially proximate friends and relatives. The plain ware data are compared to boundaries derived from settlement patterns, rock art, public architecture, and painted ceramics to characterize the overall nature of social boundaries in Late Prehistoric central Arizona. Three regions in the study area are strongly integrated by relational networks and categorical commonality. If alliances existed in Late Prehistoric central Arizona, they were most likely to emerge at this scale. A fourth region is identified as a frontier zone, where internal connections and shared identities were weaker. As seen among the League of the Iroquois, smaller integrated entities do not preclude the existence of larger social constructs, and I conclude this study with proposals to further test the Verde Confederacy model by searching for integration at a broader spatial scale.
Social Network Analysis in Economic Archaeology-Perspectives from the New World
2019
Understanding connectivity is a key to understanding decision making. Social network analysis offers formalized ways of describing and thus comparing attributes of actors related to each other in networks. Using quantitative spatial data, social network analysis promises deeper insights into how social positions are achieved and developed, as mirrored in the ancient fl ows of materials. The volume collects contributions of an international conference on network analysis in archaeology, held in 2015 at the University of Cologne as part of the DFG Research Training Group 1878 'Archaeology of Pre-Modern Economies'.
The Heterogeneity of Social Network and Institutional Covariance in the American Southeast
American Antiquity
Social, political, and economic institutions covary with one another in heterogenous ways across space and time. Social Network Analysis (SNA) offers a set of analytical tools and conceptual frameworks that have allowed for formal comparisons of interactions, affiliations, and relationships in reconstructing historical trajectories of institutional change. Although archaeologists have made full use of a range of metrics that describe the structural variation of social networks, formal approaches to analyzing the covariance of networks, and the institutions that structured networks in the past, remain undertheorized. In most cases, descriptive metrics are compared between networks built from different datasets or networks separated in time. Using quadratic assignment procedure (QAP) correlations to compare matrices of archaeological data, I draw on a ceramic dataset of approximately 350,000 sherds from the Southern Appalachian region to investigate how decisions related to manufacture choice and to stylistic design covaried with one another between roughly AD 800 and 1650. I explore how material attributes may or may not vary independently of one another and what that means for our analyses of the institutions they reflect. The results contribute to broader comparative analyses of institutional change and perennial discussions of social evolution.
