Understanding the risk factors for violence and criminality in women: the concurrent validity of the PCL-R and HCR-20

This study explores the performance of 132 female maximum-security inmates on the Psychopathy Checklist-Revised (PCL-R) and the HCR-20 (Historical, Clinical, and Risk Management Scheme) to examine the concordance between these two risk assessment instruments, and to assess their potential usefulness in determining level of risk for violent behavior and other forms of criminality. The two instruments demonstrated consistent and highly significant correlations across total scores, factor scores, and subscale scores. When the two instruments were entered into a multiple regression analysis to predict violent and non-violent crime, the HCR-20 did not add to the variance explained by the PCL-R. These results confirm earlier research that suggests that there is little or no difference between these two risk assessment instruments in their relationship to community or institutional violence. Further, Receiver Operating Characteristics (ROC) analyses show that both instruments demonstrated an inverse ability to predict convictions for murder, a close to chance ability to predict violent crime, but a shared ability to predict property and minor crime. Broadly, these results suggest that psychopathic women are involved in chronic patterns of non-violent criminality, while women charged and convicted of murder generally do not have elevated scores on the PCL-R or HCR-20. The relevance of these findings to rehabilitation and treatment is discussed.     

Normal responses to sexually anatomically detailed dolls

The behaviors and verbalizations of normal, preschool age boys and girls during interactions with sexually anatomically detailed (SAD) dolls were examined. A structured, nonsuggestive interview with each child was videotaped, and five behaviors and five verbalizations were coded for each of five phases of the interview. A two-way ANOVA (gender × phase) showed that during those phases when the dolls were undressed, both boys and girls showed more sexual exploratory play, aggressive behavior which was nonsexual, and active avoidance. Across all phases, nonsexual aggression accounted for 31% of the boys' and 22% of the girls' total responses. Behavioral and verbal sexual exploratory play represented 42% of the boys' responses and 50% of the girls' responses. In contrast, sexually aggressive behavior accounted for only 1% and 2% of the boys' and girls' responses, respectively. Girls interacted with the dolls more than did boys. Additionally, girls demonstrated more affection to the dolls than did the boys, and boys displayed more anxiety with the dolls than did girls. Investigators should be cautious as to inferences about preschoolers' interactions with SAD dolls, especially interactions of a sexual or aggressive nature which do not clearly depict fondling or intercourse.     

The Effect of Clothing on the Rate of Decomposition and Diptera Colonization on Sus scrofa Carcasses

Twenty Sus scrofa carcasses were used to study the effect the presence of clothing had on decomposition rate and colonization locations of Diptera species; 10 unclothed control carcasses were compared to 10 clothed experimental carcasses over 58 days. Data collection occurred at regular accumulated degree day intervals; the level of decomposition as Total Body Score (TBS_surf), pattern of decomposition, and Diptera present was documented. Results indicated a statistically significant difference in the rate of decomposition, (t₄₂₇ = 2.59, p = 0.010), with unclothed carcasses decomposing faster than clothed carcasses. However, the overall decomposition rates from each carcass group are too similar to separate when applying a 95% CI, which means that, although statistically significant, from a practical forensic point of view they are not sufficiently dissimilar as to warrant the application of different formulae to estimate the postmortem interval. Further results demonstrated clothing provided blow flies with additional colonization locations.     

The Gendered Face of Partisan Politics: Consequences of Facial Sex Typicality for Vote Choice

Facial cues are consequential for voters’ behavior at the polls. Yet the facial cues that are associated with vote choice remain under-examined. We predicted that vote choice judgments rely, in part, on the sex typicality of facial cues (i.e., the degree of facial masculinity and femininity) that vary as a function of candidate gender and partisan identification. Stimuli included image pairs of winners and runners-up in the elections for the 111th U.S. House of Representatives. In Study 1, we found that female Republican candidates who appeared relatively more feminine and male Republican candidates who looked relatively less masculine in their appearance were more likely to win their election. Democratic candidates’ electoral success was not related to their sex typicality. In Study 2, we found that relatively masculine-appearing Democrats and feminine-appearing Republicans were more likely to be selected in a hypothetical vote choice task. Implications for U.S. partisan politics are discussed.     

Plea decision-making by attorneys and judges

Objectives

Approximately 95 % of convictions in the United States are the result of guilty pleas. Surprisingly little is known about the factors which judges, prosecutors, and defense attorneys consider in these decisions. To examine the legal and extralegal factors that legal actors consider in plea decision-making, we replicated and improved upon a 40-year-old study by asking legal actor participants to review a variety of case factors, and then make plea decisions and estimate sentences for pleas and trials (upon conviction).

Methods

Over 1,500 defense attorneys, prosecutors, and judges completed an online survey involving a hypothetical legal case in which the presence of three types of evidence and length of defendant criminal history were experimentally manipulated.

Results

The manipulated evidence impacted plea decisions and discounts, whereas criminal history only affected plea discounts (i.e., the difference between plea and trial sentences). Defense attorneys considered the largest number of factors (evidentiary and non-evidentiary), and although legal actor role influenced the decision to plead, it did not affect the discount.

Conclusions

In replicating a landmark study, via technological advances not available in the 1970s, we were able to increase our sample size nearly six-fold, obtain a sample representing all 50 states, and include judges. However, our sample was nonrepresentative and the hypothetical scenario may or may not generalize to actual situations. Nonetheless, valuable information was gained about the factors considered and weighed by legal actors.

     

Identification of organic pigments in automotive coatings using laser desorption mass spectrometry

When one looks at an automotive coating, one sees color due to pigments. Modern organic pigments, with high molar absorptivities, may be only minor components of the mixture. Laser desorption mass spectrometry (LDMS) has been shown to be a useful tool for the analysis of colorants such as pen ink dyes. Here, LDMS is used to determine its utility for the identification of pigments, in simple media and in more complex paints. Small paint chips can be introduced into the LDMS instrument, and when an ultraviolet laser is focused on a portion of a chip, ions representative of the pigment(s) are selectively formed. Some pigments such as quinacridones and copper phthalocyanine are very stable and are desorbed and ionized intact. In contrast, benzimidazolones, which contain some single-skeletal bonds, form fragment ions. This method proves to be sensitive and convenient, as no sample preparation is required. The presence of inorganic pigments in addition to modern organic pigments can be determined, and pigments can be directly identified in actual automotive paint chip samples.
