The knowledge of opinion leaders to a certain extent has always been taken for granted by communication scholars. This article investigates what opinion leaders really know. Two studies will be presented to answer the above question. Participants of the first study were assessed according to ratings on three scales of opinion leadership, personality strength and political knowledge. In the second study, respondents were assessed according to ratings of opinion leadership and political knowledge. In both studies, it was found that opinion (...) leaders can be divided into ‘informed opinion leaders’, who know a lot in their area of interest, and ‘uninformed opinion leaders’, who are ill-informed about the field they claim as theirs. In both studies ‘informed opinion leaders’ read newspapers approximately one hour longer per week than ‘uninformed opinion leaders’. (shrink)

In previous research, cultural proximity has been operationalized by ‘hard facts’ such as geographical distance, the exchange of goods or persons and the similarity of political systems. This article will try to complement current work in the field by suggesting a new operationalization derived from Hofstede's cultural dimensions. A survey was conducted in eight countries with a student sample to find out if international audiences which resemble each other in terms of Hofstede's cultural dimensions have similar attitudes towards U.S. prime-time (...) fictional programming. The results show that Hofstede's four cultural dimensions significantly differentiate between the U.S.A., Asian and European countries in a student population. However, operationalizations based on geographical distance allow a better differentiation between nation-states in terms of how they evaluate U.S. fiction. It will be discussed whether cultural dimensions in general are able to measure cultural proximity. (shrink)
