Violent men: ordinary and deviant

This article deals with discourses of intimate partner violence and is based on interviews with professionals who meet violent men. The professionals emphasized the importance of men taking unreserved responsibility for their violent behavior. Intimate partner violence was viewed not only as "power and control" but as the result of complex situations and interplays. The discourses presented an ambivalent explanation of violent men as both ordinary and deviant. They were understood as having a strained background, but to be rather ordinary, often functioning well at work and in society. Yet, they have nonstandard views of women, act deviant in their communication and interplay with others, and cannot cope with certain situations in intimate relationships. Based on the interviews, men inclined to partner violence may be generalized as those who: attack immediately, explode unexpectedly, or ultimately become aggressive. The discussion challenges unreflected discourses as means for change when counteracting violence.     

Testing repeatability and error of coordinate landmark data acquired from crania

This study evaluates issues of precision, repeatability, and validation in three-dimensional (3D) landmark coordinates. Two observers collected 19 homologous cranial landmarks from three skulls during three separate digitizing sessions. Statistical analysis was conducted on the 171 interlandmark distances (ILDs) derived from the original coordinate data. A mixed model ANOVA detected significant within-subject error in 54 of the 171 ILDs (i.e., 32%). A GLM procedure revealed significant between-observer variation in 14 ILDs and significant observer-by-session differences in 13 ILDs. The majority of these differences involved ILDs with type 3 landmarks as endpoints, such as euryon and alare. Unlike type 1 and 2 landmarks which are biologically informative in all directions, type 3 landmarks contain a substantial arbitrary component. Thus, it is not surprising type 3 landmarks displayed significant digitizing error. Given these results, we caution researchers to be mindful of type 3 landmarks measurement discrepancies when selecting landmarks for coordinate data evaluation.     

Evaluation and quantification of nuclear DNA from human telogen hairs

Nuclear DNA was extracted from human telogen hairs from 60 individuals. Six to nine hairs from each individual were individually extracted. The amount of DNA recovered from each individual varied greatly, and most samples yielded a quantity of 550 pg or less per hair. A selective extraction buffer was used to remove epithelial cell DNA and the amount of exogenous DNA was determined. DNA was also quantified by real time PCR using three different sized amplicons targeting an Alu sequence. The results were used to determine the state of degradation of the extracted DNA. Different quantities of sample (<100 pg, 100-500 pg, >500 pg) were amplified with the Miniplex kits to determine the minimum DNA template required for successful amplification. DNA recovered from hair showed degradation; however, partial profiles were obtained for those samples containing at least 60 pg using MiniSTRs.     

A comparison of memory for homicide, non-homicidal violence, and positive life experiences

Defendants commonly claim amnesia for their criminal actions especially in cases involving extreme violence. While some claims are malingered or result from physiological factors, other cases may represent genuine partial or complete amnesia resulting from the psychological distress and/or extreme emotion associated with the perpetration of the crime. Fifty Canadian homicide offenders described their memories of their homicide, a non-homicide violent offense, and their most positive adulthood life experience. Self-reported and objective measures of memories for these events revealed that homicides were recalled with the greatest level of detail and sensory information. Although dissociative tendencies were associated with a self-reported memory loss, objective measures of memory quality did not reflect this perceived impairment, suggesting a failure of meta-memory. Recollections of positive life events were superior to those of non-homicidal violence, possibly due to greater impact and meaning attached to such experiences. Findings suggest that memory for homicide typically is enhanced by the powerful emotion associated with its perpetration.     

Deconstructing Criminology’s Origin Stories

The global production of knowledge is grossly skewed to the northern Anglophone world (Hogg et al. in International Journal for Crime, Justice and Social Democracy, 6(1), 1–7, 2017; Connell 2007). It should be no surprise therefore that criminology’s origin stories are derivative of northern experiences, yet generalised as universal theories of crime causation. In this article, we argue that the origin stories of criminological theory translated the ‘darker’, ‘hairier’ and ‘muscular’ masculinities of the global south into prototypes of dangerousness. These prototypes were first articulated as scientific claims in the nineteenth century works of Lombroso, but have been refined and embedded in mainstream criminological discourses well into the present, mainly through the quantitative study of social disorganisation, ‘race’ and racialised masculinities as variables in crime causation. The paper concedes that while deeply troubling expressions of violent masculinity exist now and in the past in the global south, it is mistaken to conceive this violence simply as expressions of atavism or social disorganisation associated with a less civilised world. On the contrary, this paper argues that the violence of colonality itself has had, and continues to have, a criminogenic impact on the present.     

Testing a Novel 3D Printed Radiographic Imaging Device for Use in Forensic Odontology

There are specific challenges related to forensic dental radiology and difficulties in aligning X‐ray equipment to teeth of interest. Researchers used 3D printing to create a new device, the combined holding and aiming device (CHAD), to address the positioning limitations of current dental X‐ray devices. Participants (N = 24) used the CHAD, soft dental wax, and a modified external aiming device (MEAD) to determine device preference, radiographer's efficiency, and technique errors. Each participant exposed six X‐rays per device for a total of 432 X‐rays scored. A significant difference was found at the 0.05 level between the three devices (p = 0.0015), with the MEAD having the least amount of total errors and soft dental wax taking the least amount of time. Total errors were highest when participants used soft dental wax—both the MEAD and the CHAD performed best overall. Further research in forensic dental radiology and use of holding devices is needed.     

Making a case for personal safety: perceptions of vulnerability and desire for self-defense training among female veterans

We assessed perceptions of vulnerability and the desire for personal safety/self-defense (PS/SD) training among 67 female veterans receiving outpatient mental health treatment, primarily for post-traumatic stress disorder (PTSD) from sexual and/or physical trauma. Consistent with the literature on the impact of such training on nonclinical populations and on individuals with visual impairments, the results of this study indicate that traumatized female veterans believe that PS/SD training would be an effective and powerful addition to more traditional treatments for PTSD. Study participants indicated they believe such training would positively affect their sense of personal safety; promote increased competence in thwarting future assaults; improve their self-esteem, confidence, and assertiveness; and reduce avoidant and agoraphobic behaviors. These pilot results support the development of an adjunct intervention to augment current PTSD treatments for women veterans with histories of sexual and physical trauma.
