AbstractIn order to rationalize the high electrical conductivity of 2,5-dimethyl-N,N'-dicyanoquinonediimine radical anion salts (2,5-DM-DCNQI) of copper, silver, and lithium, we performed onedimensional energy band structure calculations of extended-Hückel type (namely Self-Consistence of Charge, SCC) for one-dimensional models of these "organic conductors". In each case, SCC yields two overlapping incompletely occupied valence bands, which give rise to some evidence for the observed high electrical conductivity, in spite of the one-electron nature of the method. Furthermore, these two frontier energy bands do not contain any metallic orbital contribution, which suggests that the electron transport takes place in the organic stack of the 2,5-DM-DCNQI ligands only.

The relation between authoritarianism and social dominance orientation was analyzed, with authoritarianism measured using a three-dimensional scale. The implicit multidimensional structure (authoritarian submission, conventionalism, authoritarian aggression) of Altemeyer’s (1981, 1988) conceptualization of authoritarianism is inconsistent with its one-dimensional methodological operationalization. The dimensionality of authoritarianism was investigated using confirmatory factor analysis in a sample of 713 university students. As hypothesized, the three-factor model fit the data significantly better than the one-factor model. Regression analyses revealed that only authoritarian aggression was related to social dominance orientation. That is, only intolerance of deviance was related to high social dominance, whereas submissiveness was not.

Adiabatic large polarons in anisotropic molecular crystals We study the large polaron whose motion is confined to a single chain in a system composed of the collection of parallel molecular chains embedded in threedimensional lattice. It is found that the interchain coupling has a significant impact on the large polaron characteristics. In particular, its radius is quite larger while its effective mass is considerably lighter than that estimated within the one-dimensional models. We believe that our findings should be taken into account for the proper understanding of the possible role of large polarons in the charge and energy transfer in quasi-one-dimensional substances.
