"PUBLICITY" AS A PROBLEM IN THE INTERNAL VALIDITY OF TIME SERIES QUASI-EXPERIMENTS

Scholars who work with time series quasi-experiments have identified "publicity" as a problem in the interpretation of such research designs. The present study utilizes three examples of the role of publicity in three social interventions: the Romanian abortion restriction of 1966; the British breathalyzer crackdown; and, the 1978 Georgia Status Offender Act. The authors conclude that publicity is most likely to be a problem in internal validity when (1) the intervention is not truly abrupt and (2) a broad "policy" is evaluated as opposed to a "program."

Public Opinion, Risk Assessment, and Biotechnology: Lessons from Attitudes toward Genetically Modified Foods in the European Union

Proponents of biotechnology argue that citizens' opposition to innovations such as genetically modified (GM) foods is rooted in emotionalism, media and nongovernmental organizations' distortions of good science, and scientific ignorance. Critics charge that this "risk management discursive" is too reductionist, exaggerates scientific capacity, inappropriately privileges scientific values over social and political values, and inaccurately captures how citizens evaluate biotechnology. This article uses ordered logit analysis applied to the responses of Europeans to a 2005 Eurobarometer survey to test the validity of these competing perspectives in the area of GM foods. Our analysis supports the arguments of those calling for the inclusion of broader discursive social, political, and cultural elements in deliberations over GM foods. Analysis also shows that citizens are less emotional in evaluating GM foods than proponents claim and supports this "new politics of knowledge" perspective, but citizens also cling more tightly to hopes that science can resolve debates with objective analysis.
