Alligator attacks in southwest Florida

The American alligator inhabits bodies of fresh water in Florida and other southeastern states. Although attacks on pets are frequent, alligator attacks on humans are relatively rare because of the animal's natural fear of man. Because of the rarity of attacks on humans, the pathologic findings and pathophysiology of death in such cases have not been well characterized in the literature. We report three cases of fatal alligator attacks that occurred in southwest Florida, each with different pathologic findings and mechanisms of death. Although the cause of death in each case was attributed to the alligator attack, the mechanisms of death differed and included exsanguination because of amputation of an extremity, overwhelming sepsis, and drowning. These cases illustrate the varied pathophysiologies associated with deaths due to alligator attacks on humans and the features that distinguish alligator bites from those of other aquatic predators.     

Assessing the Generalization of Psychopathy in a Clinical Sample of Domestic Violence Perpetrators

This study proposed that domestic violence perpetrators in a clinical sample could be categorized into distinct subgroups and that a particular subgroup of batterers would exhibit sufficient psychopathic characteristics to be clinically meaningful. Participants were interviewed in order to gather a relevant social, familial, educational, criminal, and substance abuse history. They were then administered several psychological measures including the Psychopathy Checklist: Screening Version (PCL:SV). Results lent support to the empirical batterer typology identified by Holtzworth-Munroe, A., Meehan, J. C., Herron, K., Rehman, U., & Stuart, G. L. (2000). However, despite the presence of a more antisocial subgroup, psychopathy did not consistently differentiate among batterers across the measured dependent variables.     

Alcohol and drug use among rural and urban incarcerated substance abusers

A number of prisoners use drugs. Limited information is available about the extent to which urban and urban substance abusers differ in their drug use in criminal justice settings. In addition, many believe that rural areas are protected from drug use. However, findings from this study show only marginally statistical significant differences in drug use between incarcerated rural and urban drug users. It was expected that urban drug users would be more drug career involved with consistently higher levels of drug use and associated problems. Specifically, rural drug users in this study were older at age of first use of marijuana and cocaine; report fewer years of cocaine, hallucinogen, and heroin use; and report more alcohol and sedative use. Findings from this study suggest that rural and urban drug users are similar and that rural areas may be protective from some drug use but risky for other drug use.
