Age Estimation of Infants Through Metric Analysis of Developing Anterior Deciduous Teeth

This study provides regression equations for estimation of age of infants from the dimensions of their developing deciduous teeth. The sample comprises 97 individuals of known sex and age (62 boys, 35 girls), aged between 2 days and 1,081 days. The age‐estimation equations were obtained for the sexes combined, as well as for each sex separately, thus including “sex” as an independent variable. The values of the correlations and determination coefficients obtained for each regression equation indicate good fits for most of the equations obtained. The “sex” factor was statistically significant when included as an independent variable in seven of the regression equations. However, the “sex” factor provided an advantage for age estimation in only three of the equations, compared to those that did not include “sex” as a factor. These data suggest that the ages of infants can be accurately estimated from measurements of their developing deciduous teeth.     

Are DNA data a valid source to study the spatial behavior of unknown offenders?

Studying the spatial behaviour of unknown offenders (i.e. undetected offenders) is difficult, because police recorded crime data do not contain information about these offenders. Recently, forensic DNA data has been used to study unknown offenders. However, DNA data are only a subset of the crimes committed by unknown offenders stored in police recorded crime data. To establish the suitability of DNA data for studying the spatial offending behaviour of unknown offenders, we examine the concentration and spatial similarity of detected but unsolved crimes in police recorded crime data (N?=?181,483) and DNA data (N?=?1913) over 27 Belgian judicial districts for four crime types. We established spatial similarity for certain crime types (in some districts). This offers opportunities for DNA data to be used to study unknown offenders' spatial offending behaviour. Implications for theory and research are discussed.     

多元治理视野下的多规合一——以浙江省试点县（市）为例

文章运用一元为主、多元辅补的多元治理理论分析方法,对浙江省试点县（市）“多规合一”的协调机制、编制主体、审批机制和空间管控进行了系统分析,总结提炼出“多规合一”四方面的成效,为今后其他地区“多规合一”编制工作提供经验借鉴。研究发现：一是试点地区“多规合一”的成效明显;二是本文将多中心治理理论中国化为“一元为主、多元辅补”的多元治理的理论,并用以分析“多规合一”的现状、成果、缺憾及完善路径是有效的。因此,文章研究结论为现行“多规合一”还需要从政策法律体系、编制机构和公众参与等方面完善。     

Minimum Criminal Penalties in the European Union: In Search of a Credible Justification

The EU has recently mooted the possibility of harmonising minimum penalties. ‘Minimum criminal penalties’ refers to the lowest sanction available for a judge in a concrete case. Calculating the actual penalty involves legal mechanisms that might mitigate that penalty. Comparative analysis reveals that a distinction needs to be made between minimum penalties included in national criminal codes (in abstracto penalty) and the lowest penalty that might be imposed (in concreto penalty). Although in abstracto minimum penalties are found in the criminal codes of most Member States, they are fiercely opposed in others. In concreto minimum penalties that constitute an absolute limit to the discretion of a judge are even more controversial. Against that background, this contribution reviews whether or not the EU should force the Member States to impose absolute, in concreto minimum criminal penalties. It examines the justifications presented in recent proposals in light of legal and criminological research.     

Refining Fingermark Development using Diacetylene Copolymers on Difficult Surfaces,

In further work investigating the intriguing application of diacetylene copolymers in fingermark detection, methods were developed to control (inhibit or enhance) the diacetylene polymerization reaction in fingermarks treated with a mixture of the monomers 2,4‐hexadiyne‐1,6‐bis‐(phenylurethane) (HDDPU) and 2,4‐hexadiyne‐1,6‐bis(p‐chlorophenylurethane) (HDDCPU) in acetone solution. These methods included the use of a humidity chamber to reduce the amount of background development while promoting development on the fingermark, subjecting developed fingermarks to freezing temperatures and using a solvent to remove unreacted monomer in order to inhibit the polymerization reaction. Developed fingermarks were enhanced by conventional lighting (white light, filtered light) and fast Raman mapping, which was shown to be advantageous over FTIR imaging. This study also demonstrated the applicability of diacetylene copolymer solutions in the covert detection of fingermarks on difficult surfaces. Furthermore, fingermarks were successfully developed with good ridge detail on pig skin (used as a model for human skin, a notoriously difficult surface on which to develop fingermarks).     

An Unusual Case Showing Fatal Rupture of a Gastric Ulcer or Gastromalacia? The Importance/Role of Histology for Differential Diagnosis

Gastromalacia is the acute autolytic erosion of the gastric wall. It generally occurs postmortem, and it appears as a slimy brownish black region of the wall which occurs principally in the gastric fundus. A 59‐year‐old woman died in the Emergency Department following a 2‐day period of mild abdominal pain, vomiting, and diarrhea. A forensic autopsy was performed which revealed a rupture of the gastric fundus that had caused leakage of gastric content into the abdominal cavity. There was no macroscopic evidence of peritonitis, and the stomach wall adjacent to the rupture site showed marked thinning. The gross appearance was typical of gastromalacia. In contrast, histological observations revealed the presence of an ulcer at the site of perforation and a severe acute inflammatory reaction indicating a robust reaction with an antemortem rupture.     

Recovery Rates of Human Fetal Skeletal Remains Using Varying Mesh Sizes

Human fetal skeletal elements of different gestational ages were screened with multiple mesh sizes (6.4 mm [1/4 inch], 3.2 mm [1/8 inch], 2.0 mm, and 1.0 mm) to determine their recovery rates. All remains were previously macerated, and no significantly damaged elements were used. The 6.4 mm mesh allowed a large loss of elements (63.2% overall), including diagnostic elements, while no diagnostic elements were lost when the 1 mm mesh (0.2%) was used. When using the 3.2 mm mesh, 16.2% of the bones were lost, including some diagnostic elements (primarily tooth crowns), while 7.5% were lost using the 2.0 mm mesh. The authors recommend that the potential loss of information incurred when utilizing larger mesh sizes be taken into consideration when planning recovery methods where fetal remains may be encountered and that a minimum of 1.0 mm mesh be utilized in recovery contexts known to include fetal remains.     

Validation of the full and brief Externalizing Spectrum Inventory in Dutch forensic inpatients

The Externalizing Spectrum Inventory (ESI) was designed for assessing a broad spectrum of externalizing problems, including impulsive-aggressive behavior and substance abuse. After translation of the ESI into Dutch, a computerized version of the full Dutch ESI (ESI-NL) was administered to a mixed sample consisting of inpatients in forensic and addiction care (n = 99) and non-psychiatric community participants (n = 104). Internal consistencies, test–retest reliabilities, ‘predictive’ validity of the full and 160-item ESI-NL total scores and subscales were examined, along with the correlations between these two versions. The results indicated high reliability and predictive validity for both versions and a strong similarity between the two in direct comparisons. The 160-item Dutch ESI is recommended for clinical studies on violence proneness and externalizing problem behavior.     

Massachusetts Youth Screening Instrument for mental health needs of youths in residential welfare/justice institutions: identifying gender differences across countries and settings

This study examines the use of the Massachusetts Youth Screening Instrument-Second Version (MAYSI-2) for mental health needs among 1643 youngsters in residential welfare/justice institutions in Europe and the USA, identifying gender differences across countries and settings. Overall, the MAYSI-2 appeared to be a reliable instrument among these youngsters, with only some scales falling (slightly) below the threshold of acceptable internal consistency. Girls (vs. boys) in Belgian/USA justice institutions and Swiss mixed welfare/justice institutions displayed higher scores for the angry–irritable, depressed–anxious, somatic complaints, suicide ideation scales. Also, detained girls from Belgium and Switzerland reported higher scores for traumatic experiences. No gender differences were revealed among adolescents in German welfare institutions. Our findings suggest that the MAYSI-2 may serve as a useful mental health screening instrument among youngsters in welfare/justice institutions and that girls in justice institutions and mixed welfare/justice institutions form a particularly vulnerable population with regard to mental health problems.
