A Newman-Watts graph is formed by including random links in a regular lattice. Here, the emergence of synchronization in coupled Newman-Watts graphs is studied. The whole neural network is considered as a toy model of mammalian visual pathways. It is composed by four coupled graphs, in which a coupled pair represents the lateral geniculate nucleus and the visual cortex of a cerebral hemisphere. The hemispheres communicate with each other through a coupling between the graphs representing the visual cortices. This coupling makes the role of the corpus callosum. The state transition of neurons, supposed to be the nodes of the graphs, occurs in discrete time and it follows a set of deterministic rules. From periodic stimuli coming from the retina, the neuronal activity of the whole network is numerically computed. The goal is to find out how the values of the parameters related to the network topology affect the synchronization among the four graphs.

The Impact

This paper explores African American opinion toward equal opportunity issues using a demographic-attitudinal focus. Previous explorations have focused on black-white opinion comparisons. In this analysis, attitudinal forces, particularly core values, are identified as playing an influential role in policy support. Further, these patterns of values tend to reflect those expressed by whites on similar questions: the more individualistic and conservative one is, the less likely one is to support government intervention on African Americans behalf. In responding to questions concerning governmental responsibility, higher SES African Americans express stronger support than do their lower SES counterparts. This finding suggests that those who are experiencing “glass ceilings” are concerned about government guarantees of equal opportunity, despite their individualistic beliefs. This is inconsistent with previous explorations that analyze these beliefs among disadvantaged populations. The implications of social changes in the African American community and the impact of these changes on opinion dynamics are discussed.

Opinion Formation

Around us, the society structure and external field, such as government policy, the newspaper, the internet and other mass media, play a special role in shaping the attitudes, beliefs and public opinion. For studying the role of the society structure and the external field, we propose a new opinion model based on the former models. With computer simulations of opinion dynamics, we find that the smaller the clustering coefficient and the society size, the easier the consensus phase is reached and other interesting results.
