Who Fears the HPV Vaccine,Who Doesn’t,and Why? An Experimental Study of the Mechanisms of Cultural Cognition

The cultural cognition thesis holds that individuals form risk perceptions that reflect their commitments to contested views of the good society. We conducted a study that used the dispute over mandatory HPV vaccination to test the cultural cognition thesis. Although public health officials have recommended that all girls aged 11 or 12 be vaccinated for HPV—a sexually transmitted virus that causes cervical cancer—political controversy has blocked adoption of mandatory school-enrollment vaccination programs in all but one state. An experimental study of a large sample of American adults (N = 1,538) found that cultural cognition generates disagreement about the risks and benefits of the vaccine through two mechanisms: biased assimilation, and the credibility heuristic. We discuss theoretical and practical implications.     

The relevance of the evolution of experimental studies for the interpretation and evaluation of some trace physical evidence

In order for trace evidence to have a high evidential value, experimental studies which mimic the forensic reality are of fundamental importance. Such primary level experimentation is crucial to establish a coherent body of theory concerning the generation, transfer and persistence of different forms of trace physical evidence. We contend that the forensic context, at whatever scale, will be specific to each individual forensic case and this context in which a crime takes place will influence the properties of trace evidence. It will, therefore, be necessary in many forensic cases to undertake secondary level experimental studies that incorporate specific variables pertinent to a particular case and supplement the established theory presented in the published literature. Such studies enable a better understanding of the specific forensic context and thus allow more accurate collection, analysis and interpretation of the trace physical evidence to be achieved.This paper presents two cases where the findings of secondary level experimental studies undertaken to address specific issues particular to two forensic investigations proved to be important. Specific pre-, syn- and post-forensic event factors were incorporated into the experimental design and proved to be invaluable in the recovery, analysis and in achieving accurate interpretations of both soil evidence from footwear and glass trace evidence from a broken window.These studies demonstrate that a fuller understanding of the specific context within which trace physical evidence is generated and subsequently collected, as well as an understanding of the behaviour of certain forms of trace physical evidence under specific conditions, can add evidentiary weight to the analysis and interpretation of that evidence and thus help a court with greater certainty where resources (time and cost) permit.     

Examining Procedural Justice and Legitimacy in Corporate Offending and Beyond‐Compliance Behavior: The Efficacy of Direct and Indirect Regulatory Interactions

Tom Tyler's Procedural Justice Theory has received support in a variety of studies using criminal justice authorities as the research focus. To date, the theory has not been empirically tested using corporate malfeasance as an outcome, despite evidence that procedural justice is important in achieving regulatory compliance. This study uses factorial survey methods to examine whether corporate behavior is predicted by professionals' perceptions of procedural justice and legal legitimacy. We find that procedural justice and legitimacy considerations are salient only when managers have direct contact with regulatory authorities. This supports John Braithwaite's argument that effective regulation is enhanced by microlevel interactions in which procedural justice can be effectively leveraged to promote compliance.     

Who Is Helping the Homeless? Local, State, and Federal Responses

This article examines the sources of support for services forthe homeless. It delineates the extensive role of the privatesector in both funding and actually delivering shelter, meal,and other services for the homeless. It also indicates the extentto which certain states are providing financial support forhomeless services, and the relation of new federal efforts throughprograms funded by the Stewart B. McKinney Homeless AssistanceAct to state and private activities.     

How to vote,whether to vote: Strategies for voting and abstaining on congressional roll calls

This paper develops and tests a theory of voting and abstaining on Congressional roll calls. The theoretical model assumes that the voting behavior of legislators is oriented toward reelection, and that constituents vote retrospectively. Among the predictions of the theory are that supporters of a program are more likely to abstain than opponents, that conflicted legislators are more likely to vote on the losing side (but will abstain when the vote is very close), and that indifferent legislators will abstain when votes are not close but trade their votes when the outcome is uncertain. The empirical test is based on a series of votes on appropriations for the Clinch River Breeder Reactor from 1975 to 1982. We estimate a nested logit model of, first, the probability of voting for Clinch River, and second, the probability of abstaining from the vote, conditional on preferences regarding the program. All of the empirical results are consistent with the theoretical predictions, and most are statistically significant by conventional standards. The implication is that the abstention decision, as well as yes or no votes, can be purposive, and that the pattern of abstentions is not random among supporters and opponents.The authors gratefully acknowledge research support from the Brookings Institution and the University of Michigan School of Law, and useful comments on an earlier draft by Randall Calvert, Morris Fiorina, Rodney Fort, Amihai Glazer, Keith Krehbiel, Thomas Romer, Kenneth Shepsle, Rodney Smith, Barry Weingast, the UCI Public Choice Study Group, and the Hoover Workshop on Collective Choice.     

Political determinants of population dynamics

The hypothesis that political development, involving a massive transformation of the political system, is responsible for the movement from high to low birth and death rates in national populations is discussed. The nature of the relationship between political change and changes in vital rates is first described, and a new empirical measure of the capacity and effectiveness of political systems is presented.
