[Neonaticide: frequently suspected, seldom proven].

Objective: To present an overview of pathological findings on neonaticide in the Netherlands.

Design: Retrospective descriptive study.

Method: We analyzed all autopsy reports on neonates from the Netherlands Forensic Institute for the period 1994-2011.

Variables affecting the probability of complete fusion of the medial clavicular epiphysis.

In this study, we have combined data on clavicle fusion from different studies and applied a binomial logistic regression analysis. As such, we aimed to assess whether or not variables such as sex, socioeconomic status, and ethnicity influence the probability of having mature, i.e.

Cross-sectional anthropometric study of the external ear.

This cross-sectional anthropometric study was aimed at estimating expansion of the external ear during adult life, in order to evaluate the extent to which anatomical features appearing in earprints may vary with time. A review of the literature was provided. Data extracted from photographed ears of 1353 subjects were analyzed.

Inter- and intra-individual variation in applied force when listening at a surface, and resulting variation in earprints.

We aimed to explore the level of inter- and intra-individual variation in applied force when listening at a surface, and assess the resulting variation in earprints. We further intended to identify possible sources of this variation. Forty subjects each listened twenty-four times at a surface while applied force was recorded.

Individualization of earprints : Variation in prints of monozygotic twins.

This article presents a study of the variation in the appearance of earprints from six pairs of monozygotic (MZ) twins, applying different methods with varying degrees of objectivity. By analyzing prints of MZ twins, we purposely select pairs of individuals for whom the degree of interindividual variation is low. We first provide an account of the corresponding characteristics and the differences that occur between prints from the individual members.

Earprints in forensic investigations.

This article provides an overview of the theoretical and practical issues surrounding the use of earprints in forensic research. In the first section, we provide a limited account of the history of earprints in forensic investigations and their use as evidence in court. Criticism of the use of earprints for individualization is addressed and fundamental questions that require attention are summarized.

Exploring the effect of the occurrence of sound on force applied by the ear when listening at a surface.

In this article, we explore the effect of the occurrence of a target sound on the force that is applied by the ear when listening at a surface because differences in applied force induce variation in carprints of a single ear. Forty two subjects each listened four times at a surface. During two of these listening efforts there was silence.

Exploratory study on classification and individualisation of earprints.

The FearID research project is aimed at the individualisation of earprints for the purpose of forensic research. The study presented here was carried out within the framework of this project. It intends to combine a review of what is known from literature on the classification and individualisation of earprints with results from a preliminary study of earprints.
