We investigated the differential effect of mandatory seat belt laws on seat belt use among socioeconomic subgroups. We identified the differential effect of legislation across higher versus lower education individuals using a difference‐in‐differences model based on state variations in the timing of the passage of laws. We find strong effects of mandatory seat belt laws for all education groups, but the effect is stronger for those with fewer years of education. In addition, we find that the differential effect by education is larger for mandatory seat belt laws with primary rather than secondary enforcement. Our results imply that existing socioeconomic differences in seat belt use would be further mitigated if all states upgraded to primary enforcement.  相似文献

The law discriminates against low status offenders, but so too might criminologists during the course of their research. In this paper, we address the following question: Does the social status of lawbreakers have an effect on their likelihood of being recruited to offender-based research? The answer to this question is important for reasons that extend beyond academic criminology. If criminologists discriminate, then they themselves are active agents in the reproduction of social disadvantage. If criminology is to reduce inequality, the field must first identify and reduce discriminatory behavior within its own research community.  相似文献

Consistent with theories of modern racism, we argue that white, non-Hispanic Americans have adopted a “coded,” race-neutral means of expressing prejudice toward Hispanic immigrants by citing specific behaviors that are deemed inappropriate—either because they are illegal or threatening in an economic or cultural manner. We present data from a series of nationally representative, survey-embedded experiments to tease out the distinct role that anti-Hispanic prejudice plays in shaping public opinion on immigration. Our results show that white Americans take significantly greater offense to transgressions such as being in the country illegally, “working under the table,” and rejecting symbols of American identity, when the perpetrating immigrant is Hispanic rather than White (or unspecified). In addition, we demonstrate that these ethnicity-based group differences in public reactions shape support for restrictive immigration policies. The findings from this article belie the claim of non-prejudice and race-neutrality avowed by many opponents of immigration.  相似文献

The Congress for Cultural Freedom was established in June 1950 in West Berlin with the intention of solidifying anti‐communist opinion among Western intellectuals. Despite much having already been written on its history and its relationship with the CIA, there remains a lack of clarity over its early years concerning the extent of the CIA role and the degree to which a coherent ‘strategy’ existed. This article concentrates on the various individuals and groups who were involved in the Congress' origins, and how its purpose and method was consolidated by means of its first major venture after Berlin, the ‘Masterpieces of the 20th Century’ festival held in Paris in May 1952.  相似文献
