Title:

Kinship Computing and Complexity: Cohesion, Class and Community


Abstract

P-systems are models of the empirical elementary relations of marriage and parentage in kinship networks that, to capture the general principles and empirical diversity of human kinship, use the formal representation of graphs embedded within the nodes of other graphs. These include descent nodes that embed descent-group members at various fractal levels in a tree of descent, the reproductive units or marriage nodes that encapsulate couples and the nuclear families that arise from them, and the easily demarcatable units of structural endogamy created by marital relinking. The connections between the nodes at the outer level such as marriage nodes in a P-system are especially useful in the analysis of marriage and descent, while at inner level we can describe how individuals are embedded in the kinship structure.

As shown in White and Johansen's (2006) ethnographic case study, P-system network formalisms capture not only nomographic conceptual distinctions, as between Lévi-Strauss (1949) in the theory of marriage alliance, Murdock (1949) in the extensionist theory of kinship, or Bourdieu (1977) and Harrison White (2008) in the theory of embedded social practices, but also the contrastive ideographic perspectives of different kin systems. Painstakingly concrete but formalized mathematically, P-systems, notably P-graphs and Tipp-graphs, provide a means to study how discrete changes occur over time in the elements and relational patterns of kinship systems. P-systems synthesize key elements of many different theoretical approaches, including those of complex systems, rather than endorsing favored theories. This talk presents examples of the network analyses of empirical kinship networks and what they can show us in terms of general social theory.

Within the field of kinship computing, P-systems (Harary and White 2001) incorporate and generalize the P-graph kinship network analysis of White and Jorion (1992) which traces back to a number of Parisian precursors (Weil, Guilbaud, ...). Kinship computing has contributed a wide range of substantive contributions that are reviewed here. White and Houseman (

Outline

graphs embedded within the nodes of other graphs

Marriage structure: e.g., the "motif" nodes of Tipp for marriage types, which point to subsets of nodes involved in relinking marriages.
Descent structure: e.g., nodes for lineages and sublineages

segregation of higher level descent and marriage structure from nuclear family structure

 and lineage/sublineage fractality are among the other kinds of graph embeddedness captured by P-systems.
