The International Covenant on Civil and Political Rights and the strategic shift to forced disappearance

Political leaders not only assess the costs and benefits of repression but also act strategically in their use of particular repression types. Choices amongst repression types depend partly upon leaders being held responsible for their particular actions. The codification of the international human rights regime indicated by broad ratification of the core International Covenant on Civil and Political Rights increases the likelihood of criminal responsibility, and political leaders who repress but want to avoid accountability for their actions respond strategically. These governments refrain from extrajudicial killing, which is easier to link to the government, relying instead on forced disappearances, a violation that is more difficult to tie to the incumbent regime. Using a sample of 194 countries from 1981 to 2009, we find that decreases in the use of extrajudicial killing in International Covenant on Civil and Political Rights member states are associated with increases in the use of forced disappearance. This indicates a substitution effect as governments attempt to maintain the benefits of repression while avoiding the costs of accountability. Our findings are robust to changes in measurement, sample size, and model specification.     

DNA Barcoding in Forensic Entomology – Establishing a DNA Reference Library of Potentially Forensic Relevant Arthropod Species,

Throughout the years, DNA barcoding has gained in importance in forensic entomology as it leads to fast and reliable species determination. High‐quality results, however, can only be achieved with a comprehensive DNA barcode reference database at hand. In collaboration with the Bavarian State Criminal Police Office, we have initiated at the Bavarian State Collection of Zoology the establishment of a reference library containing arthropods of potential forensic relevance to be used for DNA barcoding applications. CO1‐5P’ DNA barcode sequences of hundreds of arthropods were obtained via DNA extraction, PCR and Sanger Sequencing, leading to the establishment of a database containing 502 high‐quality sequences which provide coverage for 88 arthropod species. Furthermore, we demonstrate an application example of this library using it as a backbone to a high throughput sequencing analysis of arthropod bulk samples collected from human corpses, which enabled the identification of 31 different arthropod Barcode Index Numbers.     

The role of beliefs and trait aggression in prison bullying among young offenders

This study aimed to explore the characteristics of those involved in bullying, including trait aggression, beliefs, interpretation of potential threat and responses to aggression. Three hundred and thirteen young adult male offenders completed three measures; the Direct and Indirect Prisoner Behaviour Checklist, the Aggression Questionnaire, and the Threat Appraisal of Behaviour measure. Pure bullies and bully-victims were predicted to have higher trait aggression scores, and to be more likely to endorse beliefs supportive of aggression than other groups. Bully-victims were predicted to have higher levels of trait hostility and higher levels of fear than pure bullies. The results demonstrated that both bully groups had higher trait aggression scores, with bully-victims having higher scores on the hostility subscale than pure bullies or those not involved. Bully-victims viewed bullying as more of a threat and were more fearful of it than pure bullies and they were also more likely to endorse both aggressive and avoidant coping responses whereas pure bullies were more likely to endorse aggressive responding. Findings highlight differences between the two bully groups and offers an outline of the underpinning causes of bullying for each group.
