Adolescents' Participation in Service Activities and Its Impact on Academic,Behavioral, and Civic Outcomes

The National Household Education Survey, a nationally representative data set (N=4,306 high school students and one parent of each), was analyzed to describe characteristics of adolescents, the nature of their service activities, and academic, behavioral and civic outcomes associated with service (voluntary compared to school-required and by type of service). Participation in any service is associated with positive outcomes whether service is voluntary or required. Adolescents who worked directly with individuals in need had better academic adjustment; those who worked for organizations had better civic outcomes than adolescents who performed other types of service. Findings are discussed in terms of their significance for adolescent development, educational policy, and the use of large national data sets to examine service participation.

Suicide by self-immolation

In the Western world, self-incineration is a rare event compared with the Asian countries. The circumstances of death are often unusual, and differentiation from homicide is sometimes possible only after evaluating all the investigation results and findings. In many cases of self-cremation, a fire accelerant is used. In our study material at least 30% of the body surface were burned. Unaffected skin was predominantly found on the back of the body. The cases presented by us are inhomogenous as to the motive and differ from those reported in the literature with regard to gender distribution, scene, motivational situation and psychological constitution.     

Distinguishing Atherosclerotic Calcifications in Dry Bone: Implications for Forensic Identification

Atherosclerotic calcifications, as calcified atheromatous elements, are markers of cardiovascular disease. However, the literature gives little information regarding their morphological aspect, making their identification very rare in skeletonized cases. In this paper, we document the morphological, histological, and SEM aspects of atherosclerotic plaques collected from unclaimed cemeterial skeletal remains from an identified osteological collection and extracted from well‐preserved cadavers autopsied at the medico‐legal institute of Milan. Each of the three analyses provided similar results: atherosclerotic calcifications are convex‐concave plaques with a stratified structure, a pale‐yellow coloration in autopsy cases and yellow to brown when recovered in dry bone. Histologically, undecalcified and decalcified sections showed a stratified aspect formed by superimposed layers. Lastly, the SEM analysis showed a precise view of the stratified structure of the plaques in transverse section. As markers of disease, atherosclerotic calcifications can provide important antemortem information on the deceased that may be compared to antemortem data.
