Fatal steamer accident; blunt force injuries and drowning in post-mortem MSCT and MRI

Steamer accidents, through contact with the bucket wheel, are very seldom today. No publication of such a kind of fatal accident could be found in literature. We present the case of a fatal steamer accident, in which the findings of a blunt traumatization of a person by the ship was completely documented by post-mortem combined multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) examinations. A rupture of the aorta was detected using both radiological methods without use of radiopaque material. Radiological examination revealed a comminuted fracture of the thorax vertebrae at the same level as the aortic rupture. Injuries of the soft tissues of the back, caused by the bucket wheel of the steamer, were also diagnosed. In addition to the signs of blunt force trauma the findings of drowning such as an over inflation of the lungs, fluid in the stomach and duodenum were revealed. Furthermore, algological analysis detected diatoms in the lung tissue and blood from the left heart. Therefore, the cause of death was considered being a combination of fatal hemorrhage, caused by the aortic rupture, and drowning. We conclude that virtual autopsy using combined post-mortem MSCT and MRI is a useful tool for documentation, visualisation and analysis of the findings of blunt force trauma and drowning with a large potential in forensic medicine.     

Morphology of second and third instars of Chrysomya villeneuvi Patton (Diptera: Calliphoridae), a fly species of forensic importance

The morphology of the second and third instars of Chrysomya villeneuvi Patton, a fly species of forensic importance, was presented by use of light microscopy. Both instars were of hairy appearance, bearing elongated tubercles along the abdominal and caudal segments. The anterior spiracle had 13-15 papillae. Minute dark spots were observed to thoroughly cover the tubercle's surface, with 4-6 strong dark tips. Regarding the third instar, the intersegmental spines between the prothorax and mesothorax were heavily pigmented. The posterior spiracle had a thick and heavily pigmented incomplete peritreme. The surface and tip of the tubercles was covered with heavily pigmented sharp spines. The integument of the body was covered with numerous distinct net-like patches. A comparison with another well-known hairy maggot, Chrysomya rufifacies (Macquart), was discussed.     

Measurement Properties of the Communities That Care<Superscript>®</Superscript> Youth Survey Across Demographic Groups

Prevention science has produced information about risk and protective factors that predict adolescent drug use and related problem behaviors. This paper investigates the Communities That Care Youth Survey that measures multiple risk and protective factors. Using a sample of 172,628 students who participated in surveys administered in seven states in 1998, analyses were conducted to test the factor structure of these risk and protective factors and to test the equivalence of the factor models across five racial/ethnic groups (African Americans, Asians or Pacific Islanders, Caucasians, Hispanic Americans, and Native Americans), four grade levels (6th, 8th, 10th, and 12th) and both gender groups. Results support the construct validity of the surveys risk and protective factor scales and indicate that the measures are equally reliable across males and females and five racial/ethnic groups. Implications of these findings for science-based prevention planning are discussed.     

A NOTE ON AMERICA'S "CLOACAL" JAILS

A large literature points to the abominable condition of American jails. Comparison of national surveys of jail conditions conducted in 1972 and 1978 indicates that what little improvement has occurred is minimal compared to remaining problems. A number of factors have prevented state-set standards from achieving widespread improvement in local jail conditions: high costs, local autonomy and lack of credible threats for forcing compliance. The failure of New York State to implement adequate health standards illustrates the limitations of the standards approach. Other approaches, such as strategies for replacing local jails with regional facilities, deserve the attention of policy researchers.     

POLITICIANS AND THE DISTRIBUTION OF PUBLIC POLICIES

Policy scientists can make important contributions to the study of policy distribution, a question that is likely to be among the most crucial national issues to be discussed throughout this decade. One aspect of this question that has been neglected is the theoretical assumption associated with public choice theory that politicians, once elected, will reward their supporters through the distribution of policy benefits. However, empirical research indicates that policy benefits seldom are distributed in this way. Instead, politicians follow the principle of universalism. In league with bureaucracies and policy communities, politicians define need and then ask bureaucracies to allocate benefits. This makes politicians roles as distributors of policy very different than simplistic models suggest.     

A moment in human development: legal protection, ethical standards and social policy on the selective non-treatment of handicapped neonates

Selective non-treatment decisions involving severely handicapped neonates have recently come under renewed judicial and legislative scrutiny. In this Article, the Author examines the legal, ethical and social considerations attendant to the non-treatment decision. In Part II of this Article the Author discusses the predominant ethical viewpoints relating to this issue and proposes a new moral standard based on personal interests. Part III presents a survey of the jurisprudence relating to selective non-treatment decisions. Parts IV and V of this Article provide a critical examination of the recently enacted Child Abuse Amendments of 1984, a federal legislative initiative designed to regulate treatment decisions relating to handicapped infants. The Author suggests that the ethical standards and treatment criteria proposed in this Article may prove useful to courts seeking to balance the handicapped neonate's constitutional right to privacy with the requirements of the new federal law.
