Developmental factors related to deviant sexual preferences in child molesters

The aim of this study was to investigate the relationship between developmental factors and deviant sexual preferences in child molesters. In total, 146 adult males having committed a sexual offence against a child were included in the study. Three types of factors were investigated: negative experiences during childhood, behavior problems during adolescence, and sexual criminal activity in adulthood. Negative experiences and behavior problems were assessed through a semistructured interview. The sexual criminal activity was determined using police records. Sexual preferences towards children were assessed using phallometric assessment. Hierarchical regression analyses suggested the presence of two developmental pathways. The psychosocial deficits pathway is related to a sexual interest for nonviolent sexual stimuli involving children. The sexualization pathway is associated with a sexual interest for violent sexual stimuli involving children. These two pathways are discussed in light of previous empirical findings related to the development of deviant sexual preferences in child molesters.     

Distribution and optical purity of methamphetamine found in toxic concentration in a civil aviation accident pilot fatality

Toxicological evaluation of postmortem samples collected from a pilot involved in a unique fatal civil aircraft accident is described in this paper. A one-occupant airplane was substantially damaged upon colliding with terrain in poor visibility. Remains of the pilot were found outside the aircraft. Pathological examination revealed multiple blunt force injuries and vascular congestion. The fluorescence polarization immunoassay disclosed 8.0 microg/mL amphetamines in urine. Gas chromatographic/mass spectrometric analyses determined the presence of methamphetamine (1.13 microg/mL in blood and 59.2 microg/mL in urine) and amphetamine (0.022 microg/mL in blood and 1.50 microg/mL in urine). Methamphetamine was distributed throughout the body, including the brain. The amount of methamphetamine in gastric contents was 575-fold higher than that of amphetamine. The (+)- and (-)-forms of methamphetamine were present in equal proportions in gastric contents. The methamphetamine concentration found in blood was in the range sufficient to produce toxic effects, causing performance impairment.     

Rape myth acceptance and rape proclivity: expected dominance versus expected arousal as mediators in acquaintance-rape situations

Individuals who are high in rape myth acceptance (RMA) have been found to report a high proclivity to rape. In a series of three studies, the authors examined whether the relationship between RMA and self-reported rape proclivity was mediated by anticipated sexual arousal or anticipated enjoyment of sexually dominating the rape victim. Results of all three studies suggest that the anticipated enjoyment of sexual dominance mediates the relationship between RMA and rape proclivity, whereas anticipated sexual arousal does not. These findings are consistent with the feminist argument that rape and sexual violence may be motivated by men's desire to exert power over women. Theoretical and practical implications of our findings are discussed.     

Testing the Causal Mediation Component of Dodge's Social Information Processing Model of Social Competence and Depression

In Dodge's model of “social information processing” depression is the result of a linear sequence of five stages of information processing (Annu Rev Psychol 44: 559–584, 1993). These stages follow a person's reaction to situational stimuli, such that each stage of information processing mediates the relationship between earlier and later stages. Because support for the social information processing model of depression has mainly come from retrospective examination of the literature (Annu Rev Psychol 44: 559–584, 1993), we conducted a three wave prospective study including 92 adolescents without lifetime or current depression. Depressive symptoms and information processing were assessed by using well established measures employed in previous studies. The social information processing model was supported by cross-sectional results of our study. Based on prospective data we could only partially support the mediation hypotheses of the model. We discuss our unexpected results in light of limitation, including applied measures and sample characteristics.

Catching history on its wings: the experience of Pambazuka News

The authors reflect on the establishment and rapid evolution of an African electronic newsletter, Pambazuka News, an initiative rooted on the one hand in the relationship between information and communication technologies (ICTs), and (on the other hand) in the struggle against impoverishment and injustices. Among the main learning points are that electronic publishing is a long-term commitment, because of the trust established between the organisation providing the service and those using it. The immediacy of the medium enables information to move around in a range of different ways, and exerts new forms of mutual accountability. There remains, however, the critical issue of how to guarantee the resources to maintain such a service without compromising the content or diluting the purpose.     

Oral fluid testing for cannabis: on-site OraLine IV s.a.t. device versus GC/MS

Saliva or "oral fluid" has been presented as an alternative matrix to document drug use. The non-invasive collection of a saliva sample, which is relatively easy to perform and can be achieved under close supervision, is one of the most important benefits in a driving under the influence situation. Moreover, the presence of Delta9-tetrahydrocannabinol (THC) in oral fluid is a better indication of recent use than when 11-nor-Delta9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) is detected in urine, so there is a higher probability that the subject is experiencing pharmacological effects at the time of sampling. In the first part of the study, 27 drug addicts were tested for the presence of THC using the OraLine IV s.a.t. device to establish the potential of this new on-site DOA detection technique. In parallel, oral fluid was collected with the Intercept DOA Oral Specimen Collection device and tested for THC by gas chromatography mass spectrometry (GC/MS) after methylation for THC (limit of quantification: 1 ng/mL). The OraLine device correctly identified nine saliva specimens positive for cannabis with THC concentrations ranging from 3 to 265 ng/mL, but remained negative in four other samples where low THC concentrations were detected by GC/MS (1-13 ng/mL). One false positive was noted. Secondly, two male subjects were screened in saliva using the OraLine and Intercept devices after consumption of a single cannabis cigarette containing 25mg of THC. Saliva was first tested with the OraLine device and then collected with the Intercept device for GC/MS confirmation. In one subject, the OraLine on-site test was positive for THC for 2 h following drug intake with THC concentrations decreasing from 196 to 16 ng/mL, while the test remained positive for 1.5 h for the second subject (THC concentrations ranging from 199 to 11 ng/mL). These preliminary results obtained with the OraLine IV s.a.t. device indicate more encouraging data for the detection of THC using on-site tests than previous evaluations.
