The generality of criminal behavior: A confirmatory factor analysis of the criminal activity of sex offenders in adulthood

The presence of a general construct of deviance had not been investigated in sex offenders in spite of the presumption of specialization that characterized them. Consequently, the aim of this study was to investigate whether sex offenders' criminal behavior could be explained by a general construct of deviance. A semi-structured interview was conducted with each subject in order to assess deviant behavior during the life course. The official criminal behavior of 388 convicted sex offenders was analyzed using confirmatory factor analysis. The pattern of covariance observed showed that the onset, frequency, and variety of criminal activity in adulthood could be explained by a general construct of deviance in sexual aggressors. The results, however, also suggested that child molesters' frequency of sexual crime was not part of a general construct of deviance. In other words, the offending behavior of sexual aggressors of women was predominantly versatile, whereas that of sexual aggressors of children tended to be more specific, at least for one dimension of their criminal activity.     

Sensitivity of various study technics in blood stains

Quadratic pieces of fleece measuring 16 mm2 were soaked with 10 different blood-samples in the dilution steps of 1:1, 1:10, 1:100, 1:1000, respectively, and were tested in blood group typing and identification tests of forensic serology. The above spezified dilutions correspond with 5 microliters, 0.5 microliter, 0.05 microliter and 0.005 microliter of blood, respectively. The detection limit of the microspectrometric test for blood was the dilution 1:10, of the porphyrine test a dilution above 1:100, whereas the preliminary test for blood (peroxidase) succeeded always up to a dilution of 1:1000 and the species determination by the radial immunodiffusion test in agar gels succeeded in most cases op to a dilution of 1:1000. The detection limit of the anti-human globulin inhibition test was between the dilution steps 1:10 and 1:100 when non-titrated and undiluted anti-human globulin serum was used. Gc- and ABO-grouping were possible up to a dilution of 1:100 and were thus the most sensitive grouping systems. Phenotyping of the enzyme-systems and the Gm/Km-system usually required stains with considerably higher blood concentrations i.e. stains of undiluted blood.     

A Prospect Theory Analysis of California's Initiatives in Implementation of its Zero Emission Vehicles (ZEV) Mandate1

In 1990, the state of California passed the pioneering mandate on zero emission vehicles (ZEV). This technology‐forcing regulation is aimed at improvement of air quality and protection of public health from the adverse effects of air pollutants from automobiles. Facing severe opposition from the auto industry, the mandate has been revised a number of times, most recently in 2003, whereby the requirement for ZEVs have been made to align with the pace of technology development. Review of strategies used in implementation of the mandate has revealed greater emphasis on the economic incentives for rather than on environmental merits of ZEVs. Using prospect theory as the framework for analysis, the reasons have been explored. The findings of the study help us to understand how decisions are made with respect with to deviations from a mental anchor point and through the process of evaluation of losses and gains.
