This paper reports and analyses survey data on the opinions of 353 top position‐holders in business, trade unions, federal and state politics, the Commonwealth Public Service, mass media, national voluntary associations, and major universities and research institutes during the latter half of 1975. Patterns of elite responses to 15 issue sets aggregating 46 separate opinion items are examined. The main focus is on the extent and configuration of elite conflict and consensus over economic policy, foreign and defence policy, industrial relations, social issues, and institutional structure. In general, substantial conflict between left‐of‐centre and right‐of‐centre elites in all major issue areas, save possibly that of social issues, is found. However, the extent of this conflict varies as between specific policies, over which it is relatively small, and the legitimacy or desirability of various group actions and major policy innovations, over which it is quite large. Whether conflict during 1975 was sufficiently great to threaten the fundamental unity of Australian elites is discussed.  相似文献

Since he was convinced that men of virtue were the exception rather than the rule, the primary political problem for Hobbes was how best to guarantee the adherence of men in general to the civil law. Hobbes' solution to this problem appears at times to be inconsistent. This was not the case; Hobbes was advancing two separate, though complementary, theories as to why men do in fact obey the civil law. Whether or not there is a similar kind of duality in Hobbes' argument concerning why men ought to obey lawful authority is also discussed.  相似文献

It is shown that audience members actively select amongst available programmes on television. This selection is based upon the social role and situational characteristics of the viewer and it is also directly related to the reasons given by viewers for watching television.

Patterns of programme selection are related to three clusters of needs and reasons. The two most important of these are composed of needs relating to information and diversion. The least important cluster is concerned with the self and social contact.

Escape and diversion needs are satisfied by almost any programme; selection is minimal by those viewers expressing these needs. Information needs are best satisfied by news and other informational programmes, while social and self needs are best satisfied by quiz and variety programmes, popular drama and movies.  相似文献

I may be the first past president of the cag to come to the podium with two addresses ready for delivery. One is rather lengthy and formal, representative of some of my work during the last decade or so. The second is shorter and lighter in tone, rather personal, but hopefully it will be taken in the spirit in which it is offered.
I have, of course, been thinking about this address for months. A number of people have suggested that I should discuss topics of common interest, including resources management, historical geography, national parks and public land, conservation, cultural ecology, and the Canadian Arctic. In urging me to address these topics colleagues provided various reasons, ranging from neglect of the subject in Canadian geography to its relevance to public policy. I am grateful for this advice, which has not, however, prevented me from procrastinating in finally deciding upon a topic.  相似文献
