To determine the meaning(s) of the concepts Republican, Democrat, and Independent, the most frequently cited attributes of each party label were scaled in terms of their semantic centrality. An analysis of the magnitude scale values demonstrates that the labels Republican and Democrat have unique cognitive properties which easily discriminate one label from another. The most characteristic and discriminating properties refer to (1) voting, (2) electioneering, and (3) other forms of electoral behavior. Although these two labels have many strong properties over which there is considerable agreement, such consensus is lacking for the fewer and weaker properties which characterize and discriminate the label Independent. Whereas Republican and Democrat are sharply delineated, semantic inversions of one another, the concept Independent is ambiguously defined and only weakly distinguishable from other concepts.  相似文献

This study was undertaken to examine the relative contribution of paternal history of substance abuse and difficult temperament in fathers and sons on a panel of individual, family, and interpersonal risk factors shown to be associated with deviant peer affiliations among boys. Deviant peer affiliations among boys have been associated with development of a conduct disorder and early age substance use. In a sample of sons of substance abusing fathers (n =56) and normal fathers (n=94), a structural equation path analysis revealed that the conjoint influence of paternal history of substance abuse and difficult temperament in fathers and sons influenced family and interpersonal processes that, in turn, influenced the developmental trajectory of the child toward deviant peer affiliations. The full model (F=74.49, p<.001, Stability Index=0.70) explained 50% of the variance on sons' Peer Delinquency Scale scores. Implications for primary prevention are discussed.Supported by the Center for Education and Drug Abuse Research (CEDAR), Pittsburgh, PA.

Abstract

Thailand is now the linchpin in America’s Asia. As revolutionaries in Indochina continue to force a reduction of U.S. ground troops in Asia and as Washington’s commitment to Taiwan weakens, Thailand assumes increasing strategic importance for current American counterrevolutionary operations in continental Asia. This development extends a general trend which began in the early 1950s.  相似文献

The United States has been negotiating with North Korea in an effort to have it renounce its nuclear program for over a decade, since Washington negotiated an Agreed Framework in 1994. In this time, North Korea has only amassed more plutonium. The negotiations are hindered by mutual distrust and hostility, but it is doubtful whether any change in Washington's attitude toward the dprk would help solve the nuclear issue. It is the Kim regime that is the core problem. Until the regime is removed, there can be no durable peace in the region. This article suggests that with the prospect for a negotiated resolution of the nuclear issue remote, and since any attempt to remove the Kim regime militarily would entail huge costs, Washington might consider a third option: directly engaging the North Korean people.  相似文献

Following in the spirit of the Leviathan hypothesis, this paper empirically examines how the degree of local government market power influences efficiency in the local public sector. Market power is measured by the number and relative size distribution of similar government units in the same market area. To avoid confusing market power with the comparative efficiency or superiority of larger sized organizations, the relative size distribution of the individual government unit is held constant in the empirical analysis. In the empirical test, aggregate property values serve as the measure of efficiency. The empirical results suggest that aggregate property values are lower and thus efficiency suffers, in more concentrated municipal market areas, ceteris paribus, thus providing some evidence for Leviathan-type governments in Connecticut.  相似文献
