How the Indashyikirwa Intimate Partner Violence Prevention Programme in Rwanda Influenced Parenting and Violence against Children

There is increasing interest in working at the intersections of intimate partner violence (IPV) and violence against children (VAC), especially in the family, yet few programmatic strategies exist or have been evaluated to assess the combined impact of strategies on both types of violence. This paper addresses this gap by exploring the influence that Indashyikirwa—a programme designed to reduce IPV in Rwanda— had on VAC in the families of couples participating in the programme. Indashyikirwa included a 21-session couples’ curriculum, safe spaces for IPV survivors, and community activism against violence. In addition to reductions in IPV, a randomized control trial found significant reductions in parent’s reports of children witnessing IPV, parents’ attitudes condoning harsh physical punishment of children, and parents’ use of corporal punishment as discipline. This paper uses qualitative data to better understand how and why the couples’ curriculum influenced parenting and VAC. Twenty-eight participants (fourteen male-female couples) were individually interviewed at three time points, once before and twice after the couples’ curriculum implementation. Six men and six women who completed the curriculum and subsequently carried out activism were also interviewed at two time points. The data were analyzed thematically. Pathways motivating couples’ attitude and behavior changes towards children included reflecting on the consequences of IPV for children and appreciating the benefits for children of non-violent, gender equitable households. This analysis suggests that working with co-habiting couples presents a viable strategy for working to prevent IPV, VAC and promote more gender equitable family dynamics.

     

Radiographic age estimation based on degenerative changes of vertebrae

Age estimation is an important component of decedent identification. When assessing adult remains, anthropologists frequently use gross examination of skeletal elements, such as clavicles, ribs, and pubic symphyses. For fleshed bodies, this requires the removal of these elements and maceration prior to analysis. A new method was developed using radiographic imaging to estimate age from degenerative changes of the lower thoracic and upper lumbar vertebrae. This technique will complement anthropological age estimation methods in young and middle-aged adults and may serve as a stand-alone method for older individuals. Digital radiographs from 240 medical examiner cases were evaluated. The sample included 120 females and 120 males between the ages of 18 and 101 years. A 3-phased scoring system was used for the target vertebrae. Transition analysis was conducted on binned average scores and a Bayesian approach was used to assign age intervals. At the 90% credible interval, individuals in Bin 1 were under 36 years of age while those in Bin 3 were over 47 years of age. Individuals in Bin 2 showed too much age variation to be informative. No significant differences were found between males and females. These findings will be especially useful in the age estimation of older adults and may eliminate the need for skeletal sampling in medicolegal cases where advanced degenerative changes are radiographically observed in the lower thoracic and/or upper lumbar vertebrae. This method was developed for use on fleshed individuals but may also be applicable to skeletonized remains.     

Progress Toward the Determination of Correct Classification Rates in Fire Debris Analysis II: Utilizing Soft Independent Modeling of Class Analogy (SIMCA)

A multistep classification scheme was used to detect and classify ignitable liquid residues in fire debris into the classes defined by the ASTM E1618‐10 standard method. The total ion spectra (TIS) of the samples were classified by soft independent modeling of class analogy (SIMCA) with cross‐validation and tested on fire debris. For detection of ignitable liquid residue, the true‐positive rate was 94.2% for cross‐validation and 79.1% for fire debris, with false‐positive rates of 5.1% and 8.9%, respectively. Evaluation of SIMCA classifications for fire debris relative to a reviewer's examination led to an increase in the true‐positive rate to 95.1%; however, the false‐positive rate also increased to 15.0%. The correct classification rates for assigning ignitable liquid residues into ASTM E1618‐10 classes were generally in the range of 80–90%, with the exception of gasoline samples, which were incorrectly classified as aromatic solvents following evaporative weathering in fire debris.     

Representation through Participation: A Multilevel Analysis of Jury Deliberations

Fully participatory jury deliberations figure prominently in the idealized view of the American jury system, where balanced participation among diverse jurors leads to more accurate fact‐finding and instills public confidence in the legal system. However, research more than 50 years ago indicated that jury‐room interactions are shaped by social status, with upper‐class men participating more than their lower‐class and female counterparts. The effects of social status on juror participation have been examined only sporadically since then, and rarely with actual jurors. We utilize data from 2,189 criminal jurors serving on 302 juries in four jurisdictions to consider whether—and in what conditions—participation in jury deliberations differs across social groups. Our results indicate the continuing importance of social status in structuring jury‐room interactions, but also reveal some surprising patterns with respect to race and gender that depart from earlier research. We also find that contextual factors including location, case characteristics, and faction size shape the relationship between social status and participation. We conclude with a critical discussion of our results and urge other researchers to take into account contextual factors when examining how individual juror characteristics shape what happens inside the jury room.     

Testing Social Support Theory: A Multilevel Analysis of Recidivism

Purpose

Tests of social support theory have relied on aggregate crime rates as the outcome of interest, but such a focus ignores the potentially important macro-level processes and effects on individual-level behavior We thus perform the first multi-level investigation of social support theory.

Methods

Multilevel modeling is used to explore whether the two varieties of county-level social support - the presence of charitable organizations and AFDC expenditures - are associated with recidivism in a sample of Florida prison releasees.

Results

Results show that while social support explains little variation in individual-level recidivism, a combination of private and public social support may reduce the likelihood of reconviction for drug offenses.

Conclusion

Findings provide mixed evidence for the prospect that social support—whether governmental or nongovernmental—is associated with recidivism among recently-released inmates.     

Callous and unemotional traits and social cognitive processes in a sample of community-based aggressive youth

Psychopathic traits are associated with violent, aggressive behaviors and recidivism in adulthood. To increase positive treatment outcomes, it is arguably beneficial to identify and treat psychopathy as early as possible. Furthermore, because research shows that the effectiveness of behavior modification is likely to be affected by the social information-processing patterns of aggressive children, it is important to understand the relationship between conduct-disordered traits and social cognitions. The results of this study showed that callous/unemotional traits in a community-based sample of behavior-disordered youth (57 male, 19 female; 10-19 years of age; 63% African American) significantly predicted values in obtaining a tangible reward and getting into trouble or being punished. However, callous/unemotional traits, impulsivity/conduct problems, and narcissism failed to predict positive expectations regarding receiving a tangible reward, reducing aversive treatment, and demonstration of dominance. Implications for these results are presented.
