Automated Classification of Epiphyses in the Distal Radius and Ulna using a Support Vector Machine

The aim of this study was to automatically classify epiphyses in the distal radius and ulna using a support vector machine (SVM) and to examine the accuracy of the epiphyseal growth grades generated by the support vector machine. X‐ray images of distal radii and ulnae were collected from 140 Chinese teenagers aged between 11.0 and 19.0 years. Epiphyseal growth of the two elements was classified into five grades. Features of each element were extracted using a histogram of oriented gradient (HOG), and models were established using support vector classification (SVC). The prediction results and the validity of the models were evaluated with a cross‐validation test and independent test for accuracy (P_A). Our findings suggest that this new technique for epiphyseal classification was successful and that an automated technique using an SVM is reliable and feasible, with a relative high accuracy for the models.     

Manipulative relational behaviour and delinquency: sex differences and links with emotional intelligence

Trait emotional intelligence (EI) encompasses high levels of emotional understanding and is generally associated with positive outcomes. However, research has suggested that high EI might predispose some young females to delinquency. The present study investigated whether this relationship can be accounted for by a tendency towards emotionally manipulative behaviours, facilitated by high EI. Two hundred and fifty-two young adults (125 female) completed measures of EI, Machiavellianism, the managing emotions of others scale (MEOS) and self-reported delinquent behaviour. High EI females presented higher levels of delinquency, Machiavellian Tactics and morality, the supposedly prosocial MEOS behaviours enhancing and diverting and the non-prosocial behaviours worsening, inauthenticity and concealing. High-EI males reported fewer delinquent offences, high levels of MEOS prosocial enhancing behaviour and low levels of non-prosocial behaviours. We suggest that high-EI may enable manipulative relational behaviours in some females which in turn support delinquency aimed at fulfilment of social or material goals.     

A Process Evaluation of a Kentucky Court Improvement Initiative

This article describes a court improvement initiative designed to promote uniformity and improved court practice with the ultimate goal of the improvement of outcomes for children and families. The article focuses on the results of interviews and focus groups conducted as part of the evaluation of this initiative. Twelve jurisdictions were purposively selected to exhibit a range of family court and non–family court jurisdictions in rural and middle‐sized locations. The discussion of the qualitative results focuses on changes in court practice and the impact of the initiative on case time.     

AGE,GENDER, AND THE CRIME OF CRIMES: TOWARD A LIFE‐COURSE THEORY OF GENOCIDE PARTICIPATION*

This article asks whether genocide follows the age and gender distributions common to other crime. We develop and test a life‐course model of genocide participation to address this question using a new dataset of 1,068,192 cases tried in Rwanda's gacaca courts. Three types of prosecutions are considered: 1) inciting, organizing, or supervising violence; 2) killings and other physical assaults; and 3) offenses against property. By relying on systematic graphic comparisons, we find that the peak age of those tried in the gacaca courts was 34 years at the time of the genocide, which is older than the peak age for most other types of crime. We likewise find that women were more likely to participate in crimes against property and comparatively unlikely to commit genocidal murder. Symbolic–interactionist explanations of crime suggest people desist from crime as a result of shared understandings of the expectations of adulthood. We argue that this process may be turned on its head during genocide as participants may believe they are defending their communities against a perceived threat. Thus, in contrast to other criminological theories suggesting that people must desist from crime to be accorded adult status, some adults may participate in genocide to fulfill their duties as adult men.     

Relatively Permanent Pigmented or Vascular Skin Marks for Identification: A Pilot Reliability Study

In child sexual exploitation offenses, the collected evidence images often show the skin of nonfacial body parts of the criminals and victims. For identification in this scenario, “relatively permanent pigmented or vascular skin marks,” abbreviated as RPPVSM, were recently introduced as the basis for a novel biometric trait. This pilot study evaluated the interexaminer variability of RPPVSM identification. Four dermatology physicians were recruited to examine RPPVSM from 75 skin images collected from a total of 51 Caucasian and Asian subjects. The images were separated into 50 reference (“suspect”) images and 25 evaluation (“evidence”) images. The examiners were asked to perform identification by annotating RPPVSM in each of the 25 evaluation images and matching them with the reference images. The rate of misidentification was 0% while the mean rate at which examiners failed to find a match was 6%, indicating the potential of dermatology physicians performing the role of RPPVSM examiners.     

Occupational exposure to traumatic evidence and posttraumatic stress symptoms in forensic science professionals: Prevalence and patterns

Forensic science professionals are routinely exposed to potentially traumatizing evidence. This study aimed to estimate the prevalence of occupational posttraumatic stress disorder (PTSD) among forensic science professionals, identify job-related correlates of PTSD symptoms, and examine the role of social support in mitigating PTSD symptomology. In response to recruitment through the American Academy of Forensic Sciences, the American Society of Crime Laboratory Directors, and Evidence Technology Magazine, 449 forensic science professionals participated in the current study. Results found that 73.5% (n = 330) of the overall sample experienced at least one work-related traumatic event consistent with meeting Criterion A for PTSD, and these rates were higher for field-based respondents (n = 203, 87.9%). The prevalence of past-month provisional PTSD was 21.6% for the full sample. Disaggregated PTSD rates were 29.0% and 14.5% for field-based and non-field-based respondents, respectively. These rates were 6- to 8-fold higher than the past-year prevalence of PTSD in the general US population, estimated to be 3.5%, and were found to be at least as high as those observed in prior epidemiological research with non-treatment seeking members of the US military deployed to war zones in Iraq and Afghanistan. Results further showed that social support was protective against PTSD symptomology. The high rates of occupational exposure to trauma and consequent PTSD symptomology observed in this large sample of forensic science professionals highlight the under-acknowledged psychological risks of these occupations and the need for enhanced attention to mental health resources for these professionals.     

The Admissibility of the R-PAS in Court

The admissibility of the Rorschach has been a concern of forensic psychologists for many years. The focus of this debate has been the Comprehensive System, which is the most researched of the current Rorschach Systems available in the USA. However, recently, a new, competing system has been published: the Rorschach Performance Assessment System (R-PAS; Meyer et al., Rorschach Performance Assessment System: Administration, Coding, Interpretation, and Technical Manual, 2011). Using Heilbrun’s (Law and Human Behavior 16:257–272, 1992) guidelines as a framework, we examine the admissibility of this new system according to the standards outlined in Daubert (1993) and Frye (1923). We conclude that we have reservations about the admissibility of the R-PAS in court at the present time, notwithstanding ongoing work on this system.
