Classification of Porcine Cranial Fracture Patterns Using a Fracture Printing Interface,,

Distinguishing between accidental and abusive head trauma in children can be difficult, as there is a lack of baseline data for pediatric cranial fracture patterns. A porcine head model has recently been developed and utilized in a series of studies to investigate the effects of impact energy level, surface type, and constraint condition on cranial fracture patterns. In the current study, an automated pattern recognition method, or a fracture printing interface (FPI), was developed to classify cranial fracture patterns that were associated with different impact scenarios documented in previous experiments. The FPI accurately predicted the energy level when the impact surface type was rigid. Additionally, the FPI was exceedingly successful in determining fractures caused by skulls being dropped with a high‐level energy (97% accuracy). The FPI, currently developed on the porcine data, may in the future be transformed to the task of cranial fracture pattern classification for human infant skulls.     

Neonatal Limb Amputation—An Unusual Form of Postmortem Canine Predation

Cases of postmortem canine predation often involve elderly recluses and their dogs. The face, head, and genitalia are targeted. Two unusual cases of postmortem canine predation of abandoned newborns are described to demonstrate an unusual alternative pattern of mutilation related to the small size of the decedents, marked decomposition, and canine scavenging behavior. Both bodies were abandoned/concealed soon after birth and were subsequently disturbed by dogs. Both were markedly decomposed with absent arms. Other injuries included skin and soft tissue defects of the torsos, with loss of distal portions of the right foot and the left lower leg in one case. No interstitial hemorrhage was observed in any of the exposed soft tissue wounds. There were no significant head or neck injuries. These cases show that patterns of postmortem canine predation will vary depending on the age, physical characteristics, degree of decomposition, and location of decedents.     

Opponent Process Theory for Substance Abuse Treatment

This article examines problems and issues of the juvenile justice and drug & alcohol systems in the context of treatment resistant, substance dependent, delinquent youth. The evaluation research on traditional medical model treatment shows high drop-out and relapse rates along with limited impact on polydrug users. Outdoor challenge programs are reviewed as an alternative within the context of Opponent-Process Theory and the therapeutic use of stress. These forms of stressful challenge may produce improved self-esteem and positive affect which may be useful as alternative forms of substance abuse treatment, especially for resistant delinquent youth who have not benefitted from more traditional forms of treatment.     

The community service self-efficacy scale: further evidence on reliability and validity

The Community Service Self-Efficacy Scale (CSSES) measures". . . the individual's confidence in his or her own ability to make clinically significant contributions to the community through service" (Reeb et al., p. 48). Three studies reported in this article replicate and extend past CSSES research. With regard to reliability, results replicate past research in demonstrating internal consistency and temporal consistency. Convergent validity was demonstrated by the finding that, as hypothesized, the CSSES correlated moderately with a measure of general self-efficacy. As hypothesized, the correlation between the CSSES and a measure of social desirability was low in magnitude and non-significant, demonstrating discriminant validity. Regarding gender differences, females tended to score somewhat higher than males on the CSSES. With respect to construct validity, CSSES scores changed in the hypothesized direction in response to an intervention. While past CSSES research focused on college students, one study reported in this paper shows that the CSSES is useful in studying adolescents, including those with psychosocial adjustment problems.
