    Abstract
    Research evaluating models of scientific productivity require coherent metrics that quantify various key relations among papers as revealed by patterns of citation. This paper focuses on the various conceptual problems inherent in measuring the degree to which papers tend to cite other papers written by authors of the same nationality. We suggest that measures can be given a degree of assurance of coherence by being based on mathematical models describing the citation process. A number of such models are developed.

    Abstract
    This paper continues the attempt of Part I to develop a coherent family of measures of influence between classes of documents, for example, language or nationality classes, as indicated by citation choice. In this paper we focus on situations in which there is some ambiguity as to how to assign items to a class. For simplicity, we change our focus from citations to co-authorship patterns, restricting most of our discussion to papers with two authors. Like the earlier paper, we propose very simple models of the citation decision, and base our measures on the parameters that appear in the model.
