Investigative and autopsy findings in sport aircraft-related deaths in southwest Florida

Aircraft designated for sport or recreational use only, including ultralights, experimental aircraft and light-sport aircraft, have become increasingly popular. Because of their relative safety and the rarity of fatalities resulting from crashes of these aircraft, the forensic literature contains little information concerning the pathologic findings in such deaths. We report 9 deaths resulting from 6 sport aircraft crashes in southwest Florida, 6 pilots and 3 passengers. The vehicles involved 3 experimental aircraft, 1 ultralight and 2 "ultralight-like" aircraft. The patterns of injuries included trauma predominantly to the chest (3 cases), abdomen (1) or head (1), as well as multiple blunt force injuries involving the chest and abdomen (1) or the head and torso (3). Extremity fractures were found in only 2 cases, whereas injuries to the symphysis pubis were found in six. No "control-type" injuries were identified. These cases illustrate the varied pathologies associated with deaths due to crashes of sport aircraft and reveal the lack of uniformity associated with the investigations of such deaths.     

Case report of suicide by inhalation of nitrogen gas

Nitrogen is an inert gas that is a normal constituent of the air that we breathe. It is a suffocating gas that does not support life and that can be a cause of death by the displacement of oxygen in the atmosphere. The majority of deaths associated with nitrogen have occurred in the setting of scuba diving. Although other suffocating gases have been used as a means of committing suicide, the literature contains little information about the use of nitrogen as a suicidal agent. A case of a 50-year-old man who committed suicide using a homemade suicide device and nitrogen gas is presented.     

An ounce of prevention...

A major theme in the apparent transformation of the criminal justice system in recent years is the commitment to shifting away from reactive responses to crime in favor of proactive prevention practices. This paper raises the question of whether the rhetoric of prevention has been translated into real substantive changes. The author argues that the activity which has occurred in response to the rhetoric of prevention is more significant as an ideology of practice and control than as a ‘solution’ to the problem of crime. For the moment, it is unlikely that an ounce of prevention will produce more than a few grams of cure.     

Relationships between characteristics of teachers and teachers' assessments of sources of information

The Researchers' primary purpose was to explore relationships between (a) urban area secondary school teachers' assessments of thirty three sources of information apt to influence their practice and (b) specific characteristics of these teachers. A sample of 245 teachers, or 61% of the set contacted, participated. Qualitative and quantitative analyses of data offered by the respondents were carried out. Both predictable and perplexing outcomes of the data analyses were documented. The Researchers concluded: a) That demographic profiles of teachers can be discerned which are related to assessments of various information sources; and b) that teachers' needs for information can be linked to preferred sources of information. They were unable to explain why variables like years of teaching experience, sex, and age were related significantly to teachers' assessments of sources of information.
