Treating Couples Who Mutually Exhibit Violence or Aggression: Reducing Behaviors that Show a Susceptibility for Violence

This work evaluated a psycho-educational, group-based, conjoint treatment for couples experiencing intimate partner violence characterized by mutual low-level physical violence and psychological aggression. The ability of the treatment program to reduce violence between partners was evaluated via a multi-method, multi-informant, multiple time point experimental design. Procedures were completed at four times: baseline/pre-treatment, post-treatment, ~six months post-treatment, and ~12 months post-treatment. At each time point, couples individually self-reported on violence in the relationship and participated in a conflict discussion during which behaviors that show a propensity toward violence (i.e., contempt, belligerence, domineering, anger, and defensiveness) were observed. Results show that the program had no direct impact on self-reported violence. However, the program did impact observed behavior; males in the treatment group showed a significant decline in behaviors that show a propensity toward violence. Although the model for females was not significant, the pattern for females was comparable to that of males.     

To allot or not to allot public services? An incomplete contract approach

Using an incomplete contract framework, we analyze the consequences of allotment in public procurement. Allotment aims at dividing a public service into several lots that can be awarded to different operators. This increases the number of bidders during the competitive tendering, as well as it reduces the size of the service managed by each operator. We model the impacts of allotment both on price and quality of public services provided under public procurement. When the quality of services depends on non-contractible efforts made by the operators during the execution of the contract, our results show that (1) the operators have higher incentives to make non-contractible efforts when there is no allotment, and that (2) allotment does not maximize the joint payoffs of the public and private parties (i.e. the total surplus), but mainly benefits public authorities representing the users of the service.     

Examining the Neighborhood Context of the Violent Offending-Victimization Relationship: A Prospective Investigation

The persistent link between offending and victimization is one of the most robust empirical findings in criminological research. Despite important efforts to isolate the sources of this phenomenon, it is not fully understood. Much attention has been paid to the role of individual-level factors; however, few studies have systematically integrated neighborhood conditions. Using prospective data from the Pittsburgh Youth Study the current research examines a set of hypotheses regarding the interplay of neighborhood structural conditions and the victim-offender overlap. A multilevel analytical technique is applied to the data which purges time-varying covariates of all time-stable unobserved heterogeneity. Results indicate that the relationship between offending and victimization is pronounced in disadvantaged neighborhoods, while offending is not significantly related to victimization risk in contexts marked by lower levels of disadvantage. The implications of the results for theory are discussed, along with recommendations for future research.
