Suffocation due to foreign body aspiration visualized by post-mortem CT

The aspiration of a foreign body is a high-risk event in the life of an infant or toddler, which needs fast clinical diagnosis and therapy. If the respiratory tract is massively obstructed, the aspiration can be fatal, as shown in the case of an 18-month-old child. The little boy choked on a fragment of a hazelnut shell. Besides radiography and bronchoscopy, a CT scan can be of special value to visualize the foreign body. Based on the data obtained, a virtual bronchoscopy can be calculated. Compared with conventional radiography, the advantages of computed tomography are better image quality, higher indicative value and the possibility to exactly localize the foreign body in the respiratory tract. In the presented case, the nutshell could be visualized in the larynx before autopsy.     

Undetected and detected child sexual abuse and child pornography offenders

Current knowledge about risk factors for child sexual abuse and child pornography offenses is based on samples of convicted offenders, i.e., detected offenders. Only few studies focus on offenders not detected by the criminal justice system. In this study, a sample of 345 self-referred pedophiles and hebephiles was recruited from the community. All participants met DSM-IV-TR criteria for pedophilia or hebephilia (paraphilia not otherwise specified), were assured of confidentiality, and self-reported lifetime sexual offending against prepubescent and/or pubescent children. Two sets of group comparisons were conducted on self-report data of risk factors for sexual reoffending. Measures of risk factors address the following dimensions identified in samples of convicted offenders: sexual preferences (i.e. co-occurring paraphilias), sexual self-regulation problems, offense-supportive cognitions, diverse socio-affective deficits, and indicators of social functioning (e.g., education, employment). Men who admitted current or previous investigation or conviction by legal authorities (detected offenders) were compared with those who denied any detection for their sexual offenses against children (undetected offenders). Group comparisons (detected vs. undetected) were further conducted for each offense type separately (child pornography only offenders, child sexual abuse only offenders, mixed offenders). Although there were more similarities between undetected and detected offenders, selected measures of sexual-self regulation problems, socio-affective deficits, and social functioning data demonstrated group differences.     

Prison structure, inmate mortality and suicide risk in Europe

Suicide presents a major complication during imprisonment and greatly contributes to the high mortality rate of prisoners. All international studies have found increased suicide rates among prisoners compared to the general population. This study examines risk factors for suicide and mortality in prisoners using supranational data from the Council of Europe Annual Penal Statistics (Statistiques Penales Annuelles du Conseil du L'Europe or SPACE) from 1997 to 2008. Macrostructural risk factors for prison suicide are analyzed from this supranational data set and the identified indicators are further evaluated on the single country level. Sexual offenders, offenders charged with violent crimes and prisoners sentenced for short- and long-term imprisonment are considered to be at an elevated risk for suicide. In addition, prison mortality is associated with overcrowding.     

Representative misconduct,voter perceptions and accountability: Evidence from the 2009 House of Commons expenses scandal

This paper examines electoral accountability after the 2009–10 UK expenses scandal. Existing research shows that Members of Parliament (MPs) implicated in the scandal fared only marginally worse in the election than non-implicated colleagues. This lack of electoral accountability for misconduct could have arisen either because voters did not know about their representative's wrongdoing or because they chose not to electorally sanction them. We combine panel survey data with new measures of MP implication in the expenses scandal to test where electoral accountability failed. We find that MP implication influenced voter perceptions of wrongdoing more than expected. In contrast, constituents were only marginally less likely to vote for MPs who were implicated in the scandal. Electoral accountability may therefore be constrained even when information about representative misconduct is easily available and clearly influences voter perceptions.

Improvement in Latent Fingerprint Detection on Thermal Paper Using a One‐Step Ninhydrin Treatment with Polyvinylpyrrolidones (PVP)

Abstract: Most thermosensitive surfaces of thermal paper turn black when they come into contact with polar organic solvents such as are used in ninhydrin petroleum benzin solution. This dark staining reduces the contrast between the developed fingerprint and the background to such an extent that the identification process becomes very difficult. Integrating polyvinylpyrrolidones (PVP) into a ninhydrin solution prevents the black staining, and the developed fingerprints appear in clear contrast to the background. The new ninhydrin solution containing PVP is successful compared to the two‐step ninhydrin–acetone washing method for thermal paper which is popular in Germany.
