Fragmentation and cooperation: the evolution of organized crime in Mexico

Some researchers suggest that the observed boom in the levels of violence in Mexico since 2008 are a consequence of placing federal military forces in states with a significant organized crime presence. However, little has been said about the role of the changeable, competitive, and violent nature of criminal organizations on this increasing violence. Using the literature on inter- and intra-state conflicts as matter of analogy to explain organized crime developments in Mexico, fragmentation and cooperation seem to be determinant forces that alter the equilibrium within Mexican criminal groups, affecting their territorial control. By using a private dataset gathered by the Drug Policy Program at the Center for Economic Research and Teaching (CIDE), we examine the evolution of criminal organizations in Mexico by focusing on their different alliances and fragmentations from December 2006 to December 2011. Our analysis suggests that violence is a consequence not only of the law enforcement actions, but also of the fragmentation and cooperation within and between private groups.     

Students’ Feelings of Safety,Exposure to Violence and Victimization,and Authoritative School Climate

Although many students feel unsafe at school, few malleable factors have been identified to increase students’ feelings of safety. Drawing on criminological behavior control theories, this study posits authoritative school climate as one such factor. With data from two nationally representative datasets, this study uses path analysis to examine the relationship between authoritative school climate and feelings of safety, as well as the extent to which this relation is explained by exposure to violence and victimization. Across both datasets, a more authoritative school climate was associated with increased feelings of safety at school. Both models also indicated that this relationship was explained in part by reduced exposure to violence and victimization, although the strength of this indirect effect varied across models. These findings suggest that strengthening students’ relationships with adults and increasing the fairness and consistency of rules in the school may both reduce exposure to violence and victimization and help students feel safer at school.     

Skeletal Trauma Resulting From Fatal Low (≤3 m) Free Falls: An Analysis of Fracture Patterns and Morphologies

The skeletal trauma resulting from fatal low (≤3 m) free falls is poorly researched and understood by forensic practitioners. The aim of this study was to identify the types of skeletal trauma resulting from low falls through investigating fracture patterns and morphologies. Skeletal trauma was analyzed using full‐body postmortem computed tomography scans of 145 individuals who died from a low free fall. Trauma was then contextualized to the variables that influence how a person falls using multiple logistic regression. Results showed fracture patterning primarily involved the axial skeleton and that there were a number of patterns significantly associated with the height fallen, pre‐existing health conditions, and age. Analysis of fracture morphologies showed 108 possible fracture types, six of which were significantly associated with the height fallen. Understanding the skeletal trauma characteristic of low free falls will further inform anthropological interpretations of trauma in cases where a fall may be considered the possible mechanism.     

Quality of low secure services in the UK: development and use of the Quality of Environment In Low Secure Services (QELS) checklist

Low secure services provide care for psychiatric patients whose risk cannot be safely managed in other settings. The physical environment in these units plays an important role in supporting recovery and risk management. We developed the Quality of Environment in Low secure Services (QELS) checklist to assess the quality of the physical environment of these services. Using recommendations from previously published standards we piloted a draft checklist with a weighted scoring system reflecting the views of patients and providers. The checklist showed good criterion validity and inter-rater reliability. Data collected from 33 low secure services showed considerable variation in the quality of the physical environment. The QELS checklist provides an accessible and reliable means for managers and clinicians to assess whether the quality of the physical environment of low secure units meets recommended standards and can be used to support efforts to improve the quality of care delivered by these services.     

Interpersonal Relationships and the Development of Behavior Problems in Adolescents in Urban Schools: A Longitudinal Study

The purpose of this study was to investigate the trajectories of behavioral problems for a sample of predominately minority adolescents (n = 212, 91% African-American and/or Hispanic, 45% boys, 55% girls) in a large, urban school district and to determine the impact of parental and peer relationships, gender, and risk status on their development during middle and high school. Multi-level growth modeling was the primary statistical procedure used to track internalizing and externalizing behavioral problems across time. Results indicated that behavioral problems as rated by students’ teachers declined significantly for both boys and girls, a finding that is in direct contrast to previous studies of adolescent behavior. The quality of parental relationships was a strong predictor of both types of behavior whereas the quality of peer relationships predicted only internalizing behavioral symptoms. These findings suggest that behavioral trajectories may be somewhat unique for this population underscoring the need for additional research in this area. The findings also have implications for intervening with children and youth who display behavioral problems during critical developmental periods.     

It is and it is not: the Importance of Context when Exploring Gender Differences in Perpetration of Physical Partner Violence

The literature on gender differences in perpetration of physical partner violence (PV) consists of two opposing camps: those who emphasize gender symmetry, and those who emphasize gender asymmetry. We propose a both/and approach to this controversy by suggesting that the issue of gender symmetry is complex and dependent upon context. Furthermore, we discuss how the role of personal investment in political agendas contributes to this divide in the literature. We argue that this both/and approach to inquiry will significantly contribute to the understanding of gender differences in perpetration of PV, as well inform the development of interventions for PV.     

A psychometric typology of U.K. domestic violence offenders

A number of studies have described subtypes of domestically violent men, and the heterogeneity of domestically violent men is well established. The aim of the current study was to investigate the distribution of subtypes using psychometric measures in convicted domestically violent offenders in England. Four subtypes of offenders were identified: low pathology, borderline, narcissistic, and antisocial. These subtypes were broadly comparable with the family-only, dysphoric/borderline, and generally violent/antisocial types proposed by Holtzworth-Munroe and Stuart. The majority of the sample (60%) best fit the generally violent/antisocial profile. However, the reliance on psychometric measurement and lack of corroborative evidence from partners means that further research is necessary to test these findings.
