Biotechnology, rather than being defined as a distinct industry like steelmaking or shipbuilding, is instead a scientific knowledge base—a rapidly evolving technology—that has economically valuable applications in such diverse industries as pharmaceuticals, medical diagnostics, agriculture, bioenvironmental remediation, and chemical processing. Biotechnology has captured the imagination of ambitious scientific investigators and investors seeking high rates of return, as well as state economic development officials who hope to anchor the industry in their locality and reap the industry's economic and employment rewards. Biotech is still at an early stage of its development, and there are many competing hypotheses about its future development. Most importantly, biotechnology involves the commercialization of science resources in which the federal and state governments have made substantial investment. One key question is how to leverage this investment for future economic growth. This article explores the policy issue related to the commercialization of biotechnology, its role as an engine of economic development, and the appropriate public policy response.  相似文献

Estimates of the incidence of victim gun use from the National CrimeVictimization Survey (NCVS) are consistently lower than are those fromother studies. To examine the divergence, we conducted a survey that gaugedthe impact of methodological differences between the NCVS and the otherstudies. For half of the sample, we asked questions from the NCVS, followedby questions from the other surveys. For the other half of the sample, wepresented the questions in the reverse order. We examined two hypotheses:(1) survey methods account for the divergent results, and (2) the questionscover unrelated activities. The results provided some support for the firsthypothesis, but respondents also reported many more defenses to thequestions from the other surveys than to the NCVS questions. Consistent withthe second hypothesis, this suggests that the NCVS and the other surveysmeasure responses to largely different provocations.  相似文献

This paper analyzes the felt legitimacy of poverty and wealth in the United States, West Germany, The Netherlands, Hungary, the Czech Republic, and Russia. Several theories on poverty and wealth perception are discussed; of these, dominant ideology theory has been the most influential. This theory can predict the existence not only of a legitimizing ideology in a society, but also of challenging beliefs that incumbents of specific social positions hold. It is argued that poverty and wealth perceptions are more complex, however, involving at least three latent dimensions. Using data from the International Social Justice Project it is demonstrated that, regarding poverty, individuals distinguish between merited, unmerited, and fatalistic types of poverty. Merited poverty is poverty brought about by the individual's own doing or not doing, unmerited poverty is due to forces external to the individual, whereas fatalistic explanations attribute poverty to ascribed properties of the individual. For wealth also there are three causally relevant factors: in addition to merited und unmerited ones, a social capital factor that sees social contacts as a source for determining economic success. Using a structural equation approach and its group comparison option for comparing countries, the different explanations of poverty and wealth are translated into specific measurement models. Testing simultaneously with linear regression models show how preferences for particular explanations are shaped by stratification-related experiences and by the social position of an observer.  相似文献

The article analyzes the attributions of the causes of poverty and wealth in Russia and Estonia in 1991 and 1996 and their determinants. Among the latter are the perceived actual justice of the society, the perceived size of the middle class, and the personal position in the system of inequalities. Despite the economic hardships and a rise in inequalities in both countries, individualistic explanations of wealth and poverty have increased over the 5 years between the surveys. At the same time respondents in both countries demonstrated a growing awareness of the importance of starting positions and connections to achieve wealth. The perceived middle class has a significant effect on attributions of poverty but not on wealth. Russians in Estonia have a particular bias against wealth, whereas non-Russians in Russia are more likely to justify wealth on the basis of individual merit. Explanations of poverty and wealth in Estonia are more rooted in the factors of socialization (age, education, and gender), whereas in Russia they are more rooted in the changes in the family financial circumstances between 1991 and 1996. There was a general increase in support for government intervention in distribution in both countries.  相似文献

Spectator violence has long been associated with professional football in Europe. This article examines the issue of spectator violence from a North American perspective. We begin by noting that there is little systematic research into the scope of spectator disorder in North America. Perhaps for this reason there is little consensus about the true scale of the problem on this side of the Atlantic. It does seem clear at least that there is less spectator violence associated with professional sports in North America. After reviewing a number of explanations for this finding, we conclude that it has less to do with criminal justice policies or practices, than the social context surrounding the 'spectatorship' of sports in North America. Perhaps the most important explanation for the variance in crowd behaviour concerns the demographic profiles of sports spectators in European football and North American sports.  相似文献

Theories which suggest a relationship between crime or criminal justice variables on the one hand, and variables related to criminal justice policies on the other hand, cannot be tested without reference to historic or comparative data. Since international comparisons offer the most powerful test of such theories, policy-related research in Europe has suffered, so far, from a lack of valid comparative data. Whether crime data from different countries are comparable, has always been subject to controversies. In the case of the European Sourcebook of Crime and Criminal Justice, a network of specialists was established under the auspices of the Council of Europe in order to assess the validity of the data. Although some problems in cross-country level comparisons could not be settled, the European Sourcebook offers comparative data on 36 Member States of the Council of Europe on a variety of subjects (offences and offenders known to the police; prosecution, convictions, sentences, and corrections; survey data; and indications on manpower and budgets of police forces, prosecutors, and corrections).  相似文献
