Greater Expectations: A Field Experiment to Improve Accountability in Mali

I argue that if citizens systematically underestimate what their government can and should do for them, then they will hold politicians to a lower standard and sanction poor performers less often. A field experiment across 95 localities in Mali in which randomly assigned localities receive a civics course identifies the effect of raising voter expectations of government on their willingness to hold leaders accountable. The course provides information about local government capacity and responsibility as well as how local politicians perform relative to others, effectively raising voter expectations of what local governments can and should do. Survey experiments among individuals in treated and control communities (N = 5,560) suggest that people in treated villages are indeed more likely to sanction poor performers and vote based on performance more often. A behavioral outcome—the likelihood that villagers challenge local leaders at a town hall meeting—adds external validity to survey findings.     

I have a Facebook account,therefore I am – authentication with social networks

ABSTRACT

Social login is the use of a social network account to get access to other services. Since the internet in its architecture does not have the possibility to identify the internet user, for many services, social logins are the solution to authenticate users without the need to set up individual identity management systems. Social logins are not useful for all types of services, however, and the potential lock-in and lock-out of users needs to be considered.     

The New Panopticon? Examining the Effect of Home Confinement on Criminal Recidivism

Due to its versatility within the criminal justice system, home confinement has broad appeal as a sentencing option. This meta-analysis examines the effectiveness of house arrest and electronic monitoring on the recidivism of adult offenders. Fourteen effect sizes (from 11 studies) that present recidivistic outcomes were quantitatively pooled, and separate meta-analyses were conducted on varying categories of recidivism severity to assess the differing impact of home confinement. The findings suggest that home confinement helps adult offenders successfully reintegrate into the community upon release from closed custody and deters future offending. Implications for correctional policies and practices toward home confinement as a community-based prevention strategy to supervise offenders are discussed.     

Leadership in multiple perpetrator stranger rape

Sexual offences by multiple perpetrators are more violent and involve more severe forms of sexual violation than those perpetrated by a lone offender. Often a clear leader exists within these groups. Questions have been raised as to the relative risk of reoffending and the potentially differing criminogenic needs of leaders and followers. However, a recent study comparing leaders and followers in juvenile multiple perpetrator rapes (t'Hart-Kerkhoffs et al., 2011) failed to find some of the expected differences. It was proposed that this might be due, in part, to the way leaders and followers were classified in the study. Before work can progress in this area, it is important to devise reliable and valid means of identifying leaders and followers in multiple perpetrator rape. This article reports on a study which investigated the utility of two different methods of identifying leadership. The Scale of Influence (Porter & Alison, 2001) was applied to a sample of 256 offenders responsible for 95 multiple perpetrator rapes from the United Kingdom. Following this, the relative number of directives uttered by offenders was used to designate leadership. In 66% of the offences sampled, a leader was designated using the number of directives uttered compared with 80% when using the Scale of Influence. When combining both measures to form a composite measure of leadership, this percentage increased to 89%. Classifications of offenders as leaders, followers, and neither, according to the Scale of Influence, the count of directives, and the composite measure, were compared with classifications made by a practitioner to assess their concordance. The composite measure showed the greatest agreement with practitioner opinion. These findings suggest that the Scale of Influence could be developed to take account of other ways that leadership is displayed during multiple perpetrator rapes.     

Behavioural case linkage with solved and unsolved crimes

Offender behaviour is used to distinguish between crimes committed by the same person (linked crimes) and crimes committed by different people (unlinked crimes) through behavioural case linkage. There is growing evidence to support the use of behavioural case linkage by investigative organisations such as the police, but this research is typically limited to samples of solved crime that do not reflect how this procedure is used in real life. The current paper extends previous research by testing the potential for behavioural case linkage in a sample containing both solved and unsolved crimes. Discrimination accuracy is examined across crime categories (e.g. a crime pair containing a car theft and a residential burglary), across crime types (e.g. a crime pair containing a residential burglary and a commercial burglary), and within crime types (e.g. a crime pair containing two residential burglaries) using the number of kilometres (intercrime distance) and the number of days (temporal proximity) between offences to distinguish between linked and unlinked crimes. The intercrime distance and/or the temporal proximity were able to achieve statistically significant levels of discrimination accuracy across crime categories, across crime types, and within crime types as measured by Receiver Operating Characteristic (ROC) analysis. This suggests that behavioural case linkage can be used to assist the investigation, detection and prosecution of prolific and versatile serial offenders.     

Effects of hydrated lime and quicklime on the decay of buried human remains using pig cadavers as human body analogues

Recent casework in Belgium involving the search for human remains buried with lime, demonstrated the need for more detailed understanding of the effect of different types of lime on cadaver decomposition and its micro-environment. Six pigs (Sus scrofa) were used as body analogues in field experiments. They were buried without lime, with hydrated lime (Ca(OH)(2)) and with quicklime (CaO) in shallow graves in sandy loam soil in Belgium and recovered after 6 months of burial. Observations from these field recoveries informed additional laboratory experiments that were undertaken at the University of Bradford, UK. The combined results of these studies demonstrate that despite conflicting evidence in the literature, hydrated lime and quicklime both delay the decay of the carcass during the first 6 months. This study has implications for the investigation of clandestine burials and for a better understanding of archaeological plaster burials. Knowledge of the effects of lime on decomposition processes also has bearing on practices involving burial of animal carcasses and potentially the management of mass graves and mass disasters by humanitarian organisations and DVI teams.
