The effect of inmates' self-reported childhood and adolescent animal cruelty: motivations on the number of convictions for adult violent interpersonal crimes

Few researchers have investigated the potentially predictive power of motives for childhood and adolescent animal cruelty as it is associated with interpersonal violence in adulthood. Based on a sample of 261 inmates at medium- and maximum-security prisons in a southern state, the present study examines the relationship among several retrospectively reported motives (anger, fun, dislike, and imitation) for animal cruelty and violent crime convictions (assault, rape, and murder). Almost half reported abusing animals out of anger, whereas more than one third did so for fun. Dislike for the animal and imitation were less frequently occurring motives. Participants who abused animals at an earlier age and those who did so out of anger or for fun were more likely to repeat the offense. Regression analyses revealed that abusing an animal out of fun in their youth was the most statistically salient motive for predicting later interpersonal violence as adults.     

Intimate Partner Violence Among Adolescent and Young Adult Mothers

The associations between intimate partner violence (IPV) and mental health among adolescent and young adult mothers were compared. The sample was drawn from the Fragile Families and Child Wellbeing Study and participants were 672 mothers between the ages of 14 and 21. IPV was significantly positively associated with both depression and anxiety among young adult mothers. However, these associations were not found among adolescent mothers. In addition, IPV and marital status were significantly related among young adult mothers, but not adolescent mothers. Results suggest that IPV may have different consequences during different parts of the life course, or that mental health symptoms may be reported only later in life.

Childhood and adolescent animal cruelty methods and their possible link to adult violent crimes

Few researchers have investigated the potentially predictive power of childhood and adolescent animal cruelty methods as they are associated with subsequent interpersonal violence in adulthood. Based on a sample of 261 inmates at medium- and maximum-security prisons in a southern state, the present study examines the relationship between several retrospectively reported animal cruelty methods (drowned, hit or kicked, shot, choked, burned, and had sex) and violent criminal acts committed against humans (assault, rape, and murder). More than half of the sample reported they had shot animals, and almost half had either kicked or hit them. About one in five said they had choked animals, and about one in seven said they had either drowned, burned, or had sex with them. Regression analyses revealed that drowning and having sex with an animal was predictive of later interpersonal violence as adults.     

A simple DNA extraction method for marijuana samples used in amplified fragment length polymorphism (AFLP) analysis

As a first step in developing a molecular method for the individualization of marijuana samples, we evaluated a plant DNA extraction kit. The QIAGEN plant DNeasy method uses a spin column format for recovery of DNA and is effective for obtaining high molecular weight DNA from leaf, flower (bud), and seed samples of marijuana. The average DNA yield was 125-500 ng per 100 milligrams of fresh plant tissue. The recovered DNA was of polymerase chain reaction (PCR) quality as measured by the ability to generate reproducible amplified fragment length polymorphism (AFLP) profiles. AFLP is a technique used to create a DNA profile for plant varieties and is being applied to marijuana samples by the authors to link growers and distributors of clonal material. The QIAGEN plant DNeasy method was simple, efficient, and reproducible for processing small quantities of marijuana into DNA.     

Recent developments in medicine and law

This article focuses on certain noteworthy legislation and cases affecting medicine and law during the period September 1, 2001, to August 31, 2002. It does not attempt to discuss every case or piece of legislation, but instead seeks to summarize some of the more significant developments in this area of law.     

Animal cruelty motivations: assessing demographic and situational influences

Few studies have examined childhood and adolescent animal cruelty motives. Using a sample of 261 inmates surveyed at both medium and maximum security prisons ina southern state, the present study examined the impact of demographic attributes and situational factors relating specifically to a range of animal cruelty motivations. Almost half of the inmates who engaged in animal abuse reported committing some of the acts out of anger, whereas more than a third did so for fun. Regression analyses revealed that the most statistically salient variable in 7 of the 10 motivational models was whether animal cruelty was committed alone. Respondents who reported hurting or killing animals alone were more likely to commit the acts out of anger but less likely to have committed them to impress others, for sex, or to imitate others.
