Communicator-recipient similarity is conceptualized as having 3 dimensions: demographic similarity, att'al similarity, & situational similarity. The first 2 of these dimensions were tested in 2 factorial-design, cross-cultural persuasion exp's involving Amer & Filipino speakers & a total of 128 Filipino S's. The general hyp investigated was: The greater the communicator-recipient similarity, the greater the att change & the more favorably perceived/evaluated the communicator & the communication. Att'al similarity proved to be a more potent variable than demographic similarity. All cells showed signif before/after att change, but, contrary to what was hyp'ed, both exp's indicated that the least similar communicators were the most favorably perceived/evaluated by the recipients. These results are interpreted as instances of the disconfirmation of negative expectancies. AA.

Several leading international relations theories argue that the degree of interest similarity is an important determinant of dyadic conflict and cooperation. Empirical scholars have long wrestled with operationalizing and measuring this central, yet elusive, concept. Signorino and Ritter's (1999) S algorithm, combined with multiple data sources, provides an attractive solution to this problem. To date, however, many scholars have failed to take full advantage of this solution. In this research note we examine the properties of S via simulation and with real data sources, highlighting its virtues and potential limitations. In particular, we stress the need to include multiple data sources in the computation and provide scholars with an easy-to-use tool to greatly simplify this task.

Explanations for the democratic peace have developed along two broad lines: those that focus on democratic-specific mechanisms and those that focus on institutional similarity mechanisms. We test these competing mechanisms against each other by examining a range of regime types and a variety of institutional mechanisms, and for the first time, test them in logistic multiple regression models of rivalry onset using three rivalry datasets. Our comparative test of the two approaches largely justifies democratic-specific explanations for the democratic peace. That is, more than any other regime pairing, two democracies are less likely to engage in a rivalry. We also find some evidence that socialist single-party dyads are less likely to experience rivalry than other dyads, but overall the support for a broader institutional similarity peace is quite limited.

Kramer has shown how singularly restrictive are all 'similarity' conditions which guarantee transitivity of majority rule by limiting the family of admissible preference orderings (so-called exclusion restrictions). For suppose, plausibly, that social alternatives are points in an open convex policy space S ⊂ Rn, n ≥ 2, and that voters' preferences, {Rl)1=1…‥ l, are representable by continuously differentiable semi-strictly quasi-concave utility functions ul,. Suppose further that at a single point x ε S, any three voters' utility functions have gradients ∇ul(x), ∇uf(X), ∇uk(x), no one of which can be expressed as a positive linear combination of the other two, and no two of which are linearly dependent. Then all exclusion conditions must fail on S.

This comment focuses on Campbell's principle of proximal similarity. When considered in the light of related work in various disciplines, the principle has implications that go beyond the generalization of experimental results in preventive intervention research. The generalized principle suggests classification and conceptualization of the settings and people involved in preventive interventive research in terms offuzzy-boundary categories, in contrast to conventional classical or sharp-boundary categories. As such, the generalized principle raises opportunities (1) to use systematic, empirical methods for purposive sampling and other tasks in problem-oriented research, (2) to reconsider the epistemological foundations that shape such research, including the concept of 'science,' and (3) to include subjects with scientists in the mutually reinforcing community that is expected to evolve effective treatments. The principle is applicable to policy research in general.
