Diversity as a policy goal: The case of television

Diversity in communications is most appropriately understood as a free flow of ideas. In order to implement diversity, a comprehensive model of the communication process must be used for policy research, so that the various participants in the process can be properly restrained from abridging the free flow of ideas. The setting of priorities for implementing diversity has been illustrated using available studies of broadcast and cable television.     

“TOTALS”: Transfer of technology approached logically and systematically

Most efforts in transferring technology to a specific location are carried out following essentially a research approach. However, imposing the research approach onto a situation for which a specific solution needs to be created or restructured represents an inappropriate transfer of technology. A planning and design approach (PDA) is called for. “TOTALS” is based on planning and design concepts adapted to solving the problems of technology transfer. It is composed of six time-based and repeating phases, comprised of nineteen steps. It is based on four important concepts: a systems view of technology, a Technology Transfer Equation, five different purposeful perspectives regarding technology transfer activities, and a holistic PDA. No particular approach, technique, model or body of knowledge can be said to be predominant.     

Experiments in filtering political opinions

Changes in the wording of core measures of political attitudes in the American National Election Studies have generated a good deal of controversy about artifactual sources of change in the U.S. electorate. This research, based on several field experiments and replications, investigates the effects of using or not using various types of opinion filter questions that have appeared in the SRC/CPS series over the years. The analysis shows that the use of a filter interacts significantly with a respondent's level of education and interest in politics, particularly the latter, in determining whether a respondent will offer an opinion on a given public policy issue. But the study also demonstrates that such an interaction occurs primarily when the question about interest in politics is askedafter, rather thanbefore, a set of political issue items. In interpreting these order-and-context effects the authors develop a self-perception model of how respondents infer their interest in politics from information that isavailable in memory about their own behavior in the survey interview.     

Evaluation of automobile safety regulations: The case of compulsory seat belt legislation in Australia

A basic tenet of the new conservatism in political economy is that government policies frequently lead to unintended consequences which may offset the benefits of the policy. Auto safety legislation may be a case in point. As the first country to make the wearing of seat belts compulsory, Australia is highly suitable as a case study. Traffic accident casualties were regressed on six independent variables for the pre-seat belt period 1949–71. The equations were then used to predict casualties for the period 1972–77, using the actual values of the independent variables. In the aggregate, predicted occupant casualties were higher than the actual rates, whereas non-occupant casualties were underpredicted by the equations. An additional test, using a dummy variable to predict the effect of seat belts, supported these conclusions. The results are consistent with the hypothesis that drivers respond to a reduction in risk by increasing driving intensity, shifting some of the welfare cost of auto safety legislation on to non-occupants, whose casualty rates are higher than they would have been in the absence of seat belt legislation.I am grateful to Chris Adam and to an anonymous reviewer for helpful comments and suggestions.
