Deviant behavior and self-enhancement in adolescence

The hypothesis that “among initially high self-derogation subjects deviant response patterns (alcohol and drug abuse, delinquent patterns, etc.) are related to subsequent decreases in self-derogation” was tested with data from a longitudinal survey study of adolescents. Among higher and lower socioeconomic status (SES) males initially high self-derogation subjects who adopted (relative to those who did not adopt) any of several deviant patterns manifested significantly greater subsequent base-free decreases in self-derogation. For higher SES females only narcotics use (and among lower SES females no deviant pattern) was significantly related to subsequent decrease in self-derogation. Together with collateral data, these results indicated that where the deviant patterns were compatible with valued social roles and the subjects were able to defend against negative responses by others (but not under mutually exclusive conditions), deviant patterns functioned to reduce self-rejecting feelings among initially highly self-derogating subjects.

Identification of N,N-dimethylamphetamine formed by methylation of methamphetamine in formalin-fixed liver tissue by multistage mass spectrometry

Methamphetamine is methylated in the presence of unbuffered formalin solutions within hours at room temperature. The product, N,N-dimethylamphetamine, is also found in human liver exposed to methamphetamine followed by incubation with formalin. In the present study, a direct mass spectrometric method was developed to identify N,N-dimethylamphetamine in human liver before and after treatment with formalin. Human liver samples were obtained from four deaths that were investigated by the West Virginia Office of Chief Medical Examiner. Full toxicological analysis was conducted on samples from the decedents and methamphetamine was among the positive findings in each case. The method used to expose liver tissue to formaldehyde involved treating a small piece of liver from each case with formalin solution (20% v/v) for 24 h at room temperature. The formalin treated tissues were homogenized and the resulting suspension was sonicated for 5 min, and then centrifuged. Supernatant aliquots were directly analyzed by electrospray ionization (ESI) mass spectrometry without chromatographic isolation. Positive ion multistage mass spectra recorded in MS, MS/MS and MS/MS/MS (MS3) modes were used to confirm the presence of N,N-dimethylamphetamine and methamphetamine in the mixture. Liver tissue not treated with formalin did not contain a detectable level of N,N-dimethylamphetamine. Decreases in methamphetamine concentrations in liver tissue resulting from treatment with formalin were measured using deuterium-labeled methamphetamine as internal standard. The method can be completed in less than 2 h on thawed tissue. The results suggest that the process of fixing tissues with formalin may lead to false negative findings for methamphetamine.     

Evaluation of Effectiveness of Health Services Training Given with Different Methods in Combating of Intimate Partner Violence against Women: A Pilot Study

The study was conducted to evaluate the effectiveness of health services training provided with different methods in combating of intimate partner violence (IPV) against women. The intervention group of the study consisted of 132 healthcare workers (HCW) and 249 HCWs in the control group. According to the result of study, training given to the intervention group was more effective in increasing the knowledge level, compared to the control group. Furthermore, comparison of the HCWs in the intervention group with the control group revealed that the attitudes towards emotional, psychological and sexual violence and justifying myths changed positively. In this scope, it can be said that intervention training was effective in terms of improving knowledge and attitude on IPV. However, it is determined that the training given to both groups was inefficient in terms of turning into behaviour.     

Counterterror intelligence operations and terror attacks

We present a formal model of an intelligence agency that must divide its resources between the collection and analysis of information pertaining to terror plots. The model highlights the negative consequences of queues which form when collection exceeds analytic capacity. We incorporate the response of a terrorist organization to the operating characteristics of the intelligence system it faces, and solve for equilibrium strategies for the intelligence system and terrorist organization. Our results demonstrate the importance of properly balancing resources between collection and analysis, and stand in contrast to the observed state of overcollection in US intelligence agencies.
