Expectations and prescriptions for responding to peer aggression: The adolescent offenders' perspective

The purpose of the current research was to investigate adolescent offenders' perspectives about responses to interpersonal aggressive encounters. Specifically, participants' perspectives were assessed regarding the role of a bystander when either a friend or an acquaintance of the bystander was the victim of an aggressive act. Two aggressive acts were presented. First, the bystander witnessed an acquaintance stealing from the victim. Second, the bystander witnessed an acquaintance hitting the victim. Participants were asked to indicate (a) if the bystander would do anything (bystander expected behavior), (b) what the bystander would do (expected behavioral action), (c) if the action would be the right thing to do (evaluation of bystander expected behavioral action), and (d) what the bystander should do in response to the violation (prescribed bystander behavioral action). Results indicate that the adolescent offenders' perspectives varied as a function of offender status, type of aggressive act, as well as relationship of the victim to the bystander. Aggr.

Elderly offenders in a maximum security mental hospital

Elderly offenders aged 60 and above constitute less than 8% of the population in a maximum security mental hospital. These offenders fall into 2 groups: 1) first admission at or after the age of 50 and 2) first admission before 50. Fewer first time offenders committed homicide in the first group than those in the second group. Neuropsychiatric disturbance and sex offending was common among male first time offenders in the first group; in contrast, schizophrenia and violent offending against persons was found more often in the second group. It is argued that elderly first time offenders should be given adequate neuropsychiatric assessment. © 1995 Wiley-Liss, Inc.     

A latent variable modeling approach to identifying subtypes of serious and violent female juvenile offenders

Females have recently become an important population in research related to serious and violent juvenile offending. Although a small body of research exists on girls in the deep end of the system, very few studies have examined the degree of heterogeneity within high-risk female samples. This study applied latent class analysis (LCA) to identify subgroups of female juvenile offenders based on their self-report of offending profiles (N=133). Results supported a three-class solution with subgroups characterized by patterns of 'violent and delinquent', 'delinquency only', and 'low' offending patterns. The LCA solution was replicated in an independent sample of high-risk females. The 'violent and delinquent' class was characterized by significantly higher rates of DSM-IV diagnoses for internalizing disorders, affect dysregulation, exposure to violence (within the home, school and neighborhood), and familial histories of criminality. Implications for future research, policy and clinical practice are discussed.     

Efficacy of standard deviational ellipses in the application of criminal geographic profiling

The premise for this study is that the physical and cultural landscape has a deterministic effect on the location and distribution of serial crime. As a consequence, the distribution of linked crime scenes should exhibit a shape and orientation that is consistent with the underlying landscape. Geographic Profiling models that are able to account for these effects will provide more accurate results than those models that do not. Utilizing basic geographic principles of central tendency and spatial diffusion, this research first analyzed the output of circular and elliptical profile models generated for 30 serial burglaries (n = 164) and 67 serial robberies (n = 370) in Baltimore, Maryland between 1994 and 1997. A comparative analysis of the model output reveals that the Standard Deviational Ellipse is significantly (p = 0.000) better able to predict the home location of a serial offender than profiles generated from circles. Next, the relationship between the orientation of elliptical profiles and the mean linear orientation of the corresponding landscape was assessed to reveal a moderate but significant correlation (r = 0.511, p < 0.001). Together, these findings demonstrate that landscape does impact the locations of crime, and is a measurable parameter that can improve the efficacy of geographic profiling.

Offender and crime characteristics of female serial arsonists in Japan

This study of Japanese female serial arsonists examined their crimes and background characteristics. The data were a sample from the national police register containing arson cases resulting in charges in Japan between 1982 and 2005. Serial arsonists were 6% of the arson offenders and 12% of these were female, resulting in 83 female serial arsonist data sets. The mean age was 37.6 years and 43% were unemployed. Nearly half were married. Only 28% had a documented history of mental problems and 22% had a prior arrest, usually for theft (19%). Female serial arsonists are characterised by going to a place near their home with a lighter and setting fire directly to combustible materials. Non‐metric multidimensional scaling was used to analyse 33 variables related to the offences. The arsons could be differentiated in terms of either expressive or instrumental sources of action. Expressive arsons were opportunistic and impulsive acts, motivated by emotional distress. The fires were mostly set close to home. Expressive arsons were characteristic of 66% of the females. Instrumental arsons were often motivated by revenge and involved planned and goal‐directed behaviours. They were committed by 13% of the females. Instrumental arsonists tended to travel further from home. Copyright © 2007 John Wiley & Sons, Ltd.

Triggering Rage: Unresolved Trauma in Women’s Lives

In this qualitative study we sought to explore the triggers involved in women’s rage that are expressed towards their intimate partners. In-depth interviews were conducted with 37 incarcerated women who reported experiencing rage towards their partner. Unresolved trauma from childhood closely linked to current levels of adult rage; specific types of trauma that were reported included experiencing physical and sexual abuse, feeling unprotected by caretakers, and having observed domestic violence within their homes. Symptoms of posttraumatic stress disorder were described within the stories of rage as women recounted their experiences of intimate partner violence. Common triggers for igniting rage included women perceiving a threat to themselves, a threat to their loved ones, and emotional abuse.     

Reconsidering the two-second decay hypothesis in verbal working memory

A common belief in the study of short-term memory is that the verbal trace decays around two seconds after it is encoded. This belief is typically assumed to follow from the finding that in immediate serial recall, the time required to rapidly articulate a span-length list is around two seconds. Empirically, this belief is in opposition to a broad set of findings across a number of domains that establish mean decay times to be longer than two seconds. Theoretically, the available computational and mathematical models of immediate serial recall do not address this issue directly, because they typically rely on other mechanisms in addition to decay to account for forgetting. As such, they may show that decay times can be longer than two seconds, but they fail to show that they cannot be as short as two seconds. We address the issue directly and set a lower bound on mean trace decay times, even under the limiting assumption that all forgetting is due to trace decay. We do this by presenting a simple item-based model of trace decay that allows us to estimate values of mean trace duration. For a set of words whose span-length lists can be rapidly articulated in about two seconds, the model offers a conservative estimate for their mean decay times of around four seconds. Both the experimental and theoretical evidence show that items in verbal working memory decay considerably slower than the two-second decay hypothesis claims.
