ABSTRACTPrior taxometric research on child molesters and general sex offenders has produced inconsistent and contradictory results. There are theoretical, practical, and policy reasons, however, to assume that a psychopathy taxon may exist in sex offenders and that a taxometric study might shed light on this issue. The mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent-mode factor analysis (L-Mode) taxometric procedures were employed in three overlapping samples: 188 sex offenders with non-relative child victims, 555 sex offenders with non-relative child or adolescent victims or child incest victims, and a mixed sample of 1404 sex offenders. The taxometric analyses revealed evidence of continuous latent structure in all three samples. These results suggest that psychopathy in sex offenders, child molesters in particular, is organised quantitatively (continuous) rather than qualitatively (categorical). 相似文献

The objective of this study was to assess whether targeting new gun buyers with a public safety message aimed at improving
gun law awareness can modify gun purchasers’ behaviors. Between May 2007 and September 2008, 2,120 guns were purchased in
two target neighborhoods of the City of Los Angeles. Starting in August 2007, gun buyers initiating transactions on odd-numbered
days received a letter signed by prominent law enforcement officials, indicating that law enforcement had a record of their
gun purchase and that the gun buyer should properly record future transfers of the gun. The letters arrived during buyers’
10-day waiting periods, before they could legally return to the store to collect their new gun. Subsequent gun records were
extracted to assess the letter’s effect on legal secondary sales, reports of stolen guns, and recovery of the gun in a crime.
An intent-to-treat analysis was also conducted as a sensitivity check to remedy a lapse in the letter program between May
and August 2007. The letter appears to have no effect on the legal transfer rate or on the short-term rate of guns subsequently
turning up in a crime. However, we found that the rate at which guns are reported stolen for those who received the letter
is more than twice the rate for those who did not receive the letter (p value = 0.01). Those receiving the letter reported their gun stolen at a rate of 18 guns per 1,000 gun-years and those not
receiving the letter reported their gun stolen at a rate of 7 guns per 1,000 gun-years. Of those receiving the letter, 1.9%
reported their gun stolen during the study period compared to 1.0% for those who did not receive the letter. The percentage
of guns reported stolen in these neighborhoods is high, indicating a high rate of true gun theft, a regular practice of using
stolen-gun reports to separate the gun buyer from future misuse of the gun, or some blend of both. Simple, targeted gun law
awareness campaigns can modify new gun buyers’ behaviors. Additional follow-up or modifications to this initiative might be
needed to impact the rate at which guns enter the illegal gun market and ultimately are recovered in crimes. 相似文献
