This study examines the relationship between assessments of the risk of punishment and self-reported involvement in three illegal behaviors in a sample of college-aged respondents. It is found that those respondents who had not yet committed a particular offense were more likely to perceive a greater certainty of punishment than those with experience in committing the offense. For two of three offenses the effect of becoming involved in offending had a more substantial impact on the perceptions of those respondents with both experience in offending and high perceived certainty of punishment than on those who had experience and less pessimistic estimates of risk Finally, a multivariate analysis of the relationship between behavioral and perceptual change reveals that each variable affects the other even when other sources of change are controlled. The importance of the findings for the deterrence doctrine are discussed. 相似文献

Does the death penalty save lives? In recent years, a new round of research has been using annual time‐series panel data from the 50 U.S. states for 25 or so years from the 1970s to the late 1990s that claims to find many lives saved through reductions in subsequent homicide rates after executions. This research, in turn, has produced a round of critiques, which concludes that these findings are not robust enough to model even small changes in specifications that yield dramatically different results. A principal reason for this sensitivity of the findings is that few state‐years exist (about 1 percent of all state‐years) in which six or more executions have occurred. To provide a different perspective, we focus on Texas, a state that has used the death penalty with sufficient frequency to make possible relatively stable estimates of the homicide response to executions. In addition, we narrow the observation intervals for recording executions and homicides from the annual calendar year to monthly intervals. Based on time‐series analyses and independent‐validation tests, our best‐fitting model shows that, from January 1994 through December 2005, evidence exists of modest, short‐term reductions in homicides in Texas in the first and fourth months that follow an execution—about 2.5 fewer homicides total. Another model suggests, however, that in addition to homicide reductions, some displacement of homicides may be possible from one month to another in the months after an execution, which reduces the total reduction in homicides after an execution to about .5 during a 12‐month period. Implications for additional research and the need for future analysis and replication are discussed. 相似文献

This paper examines the theoretical import of disaggregating self-reported delinquency data into two constituent parts: (1) prevalence data, which record the proportion of any group involved in crime, reject the decision to participate in crime, and (2) incidence data, which record the frequency of offending within the subgroup of participants, reject the decision to repeat a previously committed offense. The importance of this conceptual distinction is that different causal facts may be involved in these separate offending decisions and those differences would be obscured if the data were not disaggregated. We review major delinquency theories to determine if theoretical variables are more strongly related to the prevalence or the incidence of delinquency. Multivariate models tentatively suggest that the distinction between prevalence and incidence should be maintained, although additional research with more serious offenses is needed. 相似文献
