In this paper, we analyze the average magnetization and spatial correlation of opinion formation in small-world network and in the regular lattice. We construct NW small-world network through adding shortcuts on the regular lattice. With computer simulation, we find that there exists short- and long-range spatial correlation of the average magnetization m(t) in NW small-world network and the evolution trend of opinion is dependent on the initial opinion condition by comparing with that in regular lattice. On the other hand, we analyze the average magnetization m(t) using the time series analysis, and find the Hurst exponent H ≃ 0.5 in NW small-world network and H = 0 in regular lattice. All the results show the important role of shortcuts in the NW small-world network, which reflects some interesting aspects in our real society indirectly.

Journalistic news coverage plays an essential role for providing an audience with a diverse, multifaceted perspective upon public affairs. However, in the scholarly debate, most measures of viewpoint diversity do not distinguish between statements raising commensurable interpretations, and contributions that construct different meaning in a consequential sense. We provide an operationalization of viewpoint diversity that builds upon a tradition of identifying distinct interpretations through framing analysis. Going beyond frame diversity, we then distinguish between equivalent, complementary and competing, diverse interpretations: we consider as commensurable those frames that derive from the same ‘interpretative repertoire’, a notion borrowed from discourse studies. We propose a strategy for operationalization and the measurement of viewpoint diversity. Our focus on meaningfully different interpretations contributes to advancing research into journalism, political opinion formation, audience elaboration, and other important fields of study.
