The policy process in developed and less developed political systems

The author argues that we do not really know how different the policymaking systems of developed and developing nations are. In his view, policymaking in less developed regimes is different from that which occurs in more affluent countries. However, the differences are frequently overstated. After analyzing several problems of the policymaking process, Peters concludes that the differences are larglely those of degree rather than of fundamentally different types of policy problems and processes. He concludes that what may matter is the degree of difficulty governments encounter in policymaking, and in some ways the less developed countries may actually enjoy some real advantages. At the same time, however, they have more informational, financial and ideological barriers that impose political limitations on policy learning.     

Patent ductus arteriosus as a natural cause of pulmonary hemorrhage in infants: a medicolegal dilemma

Patent ductus arteriosus (PDA) is a recognized risk factor for massive pulmonary hemorrhage (MPH) in the newborn and is generally seen in association with other MPH risk factors such as prematurity. We report 6 cases of sudden and unexpected death of infants older than 4 days with MPH and PDA at autopsy. The cases were reviewed for other factors that could contribute to MPH to ascertain whether PDA is directly linked to MPH. Histology samples were examined for distribution of hemorrhage in the lungs and iron stained for hemosiderin evaluation. All of the cases had clinical histories and scene examinations which raised the differential diagnosis of mechanical asphyxia in the form of so-called overlayings. The diagnostic dilemma of attributing the MPH to the PDA as the sole cause, dual cause, or incidental finding is discussed. These cases illustrate the medicolegal dilemma faced by the pathologist, as well as the need for further research into the potential association of PDA with MPH.     

Rationalizing criminal behaviour: the influence of criminal sentiments on sociomoral development in violent offenders and nonoffenders

Cognitive developmental theory suggests that mature-level sociomoral reasoning (Stages 3 and 4) can provide a protective factor, or buffer, against antisocial and violent criminal behavior. This study explored whether the influence of internalised criminal sentiments could undermine this buffer. The sample was high-risk men and women offenders (n = 99) convicted of serious violent index offences, and men and women nonoffender university students (n = 101). Moral reasoning was measured using the Sociomoral Reflection Measure-Short Form, whereas criminal sentiments were assessed using the Criminal Sentiments Scale. Based on moral reasoning development level the sample was classified into groups: mature- or immature-level moral reasoners. The results suggested that mature-level sociomoral development might not protect a person from identifying with criminal others, and that law violation could be rationalized regardless of sociomoral level. Gender differences were neither expected nor found. The applied implications of the findings are considered.     

Dental age estimation through volume matching of teeth imaged by cone-beam CT

A custom-made voxel counting software for calculating the ratio between pulp canal versus tooth volume based on cone-beam CT tooth images was developed and evaluated. The aim of this study was to attempt establishing a correlation between the chronological age of a certain individual and the pulp/tooth volume ratio of one of the teeth. Twenty-eight single rooted teeth of 19 individuals with well-known chronological age were scanned by the cone-beam CT (3D Accuitomo, J. Morita, Kyoto, Japan). Next the images were analyzed using the custom-made software. Linear regression analysis was performed. The results of the analysis showed a moderate correlation between the pulp/tooth volume ratio and biological age with a coefficient of determination (R2) of 0.29. Although the present work was limited to a pilot study, the developed technique showed promising results for dental age estimation in a non-invasive manner using cone-beam CT images in living individuals.
