Allegation rates in forensic child abuse investigations: Comparing the revised and standard NICHD protocols
426 4- to 13-year-old suspected victims of intra-familial abuse were interviewed using either the NICHD Investigative Interview Standard Protocol (SP) or a Revised version of this Protocol (RP) designed to both enhance rapport between children and interviewers and provide additional non-suggestive support to suspected victims who might be reluctant to make allegations. All allegations were corroborated by independent evidence documenting that the alleged abuse had indeed taken place. Analyses revealed that children were significantly more likely to make allegations of abuse when the RP rather than the SP was employed. These results suggest that supportive forensic interviewing may facilitate valid reports of abuse by young victims who might otherwise be unwilling to make allegations.This is the author accepted manuscript.

The NICHD protocol:a review of an internationally-used evidence-based tool for training child forensic interviewers
PurposeThis article reviews an evidence-based tool for training child forensic interviewers called the NICHD Protocol, with a specific focus on how the Protocol is being adapted in various countries.Design/methodology/approachWe include international contributions from experienced trainers, practitioners, and scientists, who are already using the Protocol or whose national or regional procedures have been directly influenced by the NICHD Protocol research (Canada, Finland, Israel, Japan, Korea, Norway, Portugal, Scotland, and United States). Throughout the review, these experts comment on: How and when the Protocol was adopted in their country; who uses it; training procedures; challenges to implementation and translation; and other pertinent aspects. We aim to further promote good interviewing practice by sharing the experiences of these international experts.FindingsThe NICHD Protocol can be easily incorporated into existing training programs worldwide and is available for free. It was originally developed in English and Hebrew and is available in several other languages.Originality/valueThis article reviews an evidence-based tool for training child forensic interviewers called the NICHD Protocol. It has been extensively studied and reviewed over the past 20 years. This article is unique in the it is the first to bring together practitioners who are actually responsible for training forensic interviewers and conducting forensic interviews from all around the world
Experimental Limit to Interstellar 244Pu Abundance
Short-lived nuclides, now extinct in the solar system, are expected to be
present in the interstellar medium (ISM). Grains of ISM origin were recently
discovered in the inner solar system and at Earth orbit and may accrete onto
Earth after ablation in the atmosphere. A favorable matrix for detection of
such extraterrestrial material is presented by deep open-sea sediments with
very low sedimentation rates (0.8-3 mm/kyr). We report here on the measurement
of Pu isotopic abundances in a 1-kg deep-sea dry sediment collected in 1992 in
the North Pacific. Our measured value of (3+-3)x10^5 244Pu atoms in the
Pu-separated fraction of the sample shows no excess over the expected
stratospheric nuclear fallout content and under reasonable assumptions we
derive a limit of 2x10^-11 g-244Pu/g-ISM for the abundance of 244Pu in ISM.Comment: 10 p, 1 fig, LateX(AASTeX) Accepted for publication in ApJL, aug 2,

Plasma Characterization of Hall Thruster with Active and Passive Segmented Electrodes
Non-emissive electrodes and ceramic spacers placed along the Hall thruster channel are shown to affect the plasma potential distribution and the thruster operation. These effects are associated with physical properties of the electrode material and depend on the electrode configuration, geometry and the magnetic field distribution. An emissive segmented electrode was able to maintain thruster operation by supplying an additional electron flux to sustain the plasma discharge between the anode and cathode neutralizer. These results indicate the possibility of new configurations for segmented electrode Hall thruster
A Computational Framework for Influenza Antigenic Cartography
Influenza viruses have been responsible for large losses of lives around the world and continue to present a great public health challenge. Antigenic characterization based on hemagglutination inhibition (HI) assay is one of the routine procedures for influenza vaccine strain selection. However, HI assay is only a crude experiment reflecting the antigenic correlations among testing antigens (viruses) and reference antisera (antibodies). Moreover, antigenic characterization is usually based on more than one HI dataset. The combination of multiple datasets results in an incomplete HI matrix with many unobserved entries. This paper proposes a new computational framework for constructing an influenza antigenic cartography from this incomplete matrix, which we refer to as Matrix Completion-Multidimensional Scaling (MC-MDS). In this approach, we first reconstruct the HI matrices with viruses and antibodies using low-rank matrix completion, and then generate the two-dimensional antigenic cartography using multidimensional scaling. Moreover, for influenza HI tables with herd immunity effect (such as those from Human influenza viruses), we propose a temporal model to reduce the inherent temporal bias of HI tables caused by herd immunity. By applying our method in HI datasets containing H3N2 influenza A viruses isolated from 1968 to 2003, we identified eleven clusters of antigenic variants, representing all major antigenic drift events in these 36 years. Our results showed that both the completed HI matrix and the antigenic cartography obtained via MC-MDS are useful in identifying influenza antigenic variants and thus can be used to facilitate influenza vaccine strain selection.

Forensic interviewing of mentally disordered suspects: The impact of interview style on investigation outcomes.
The investigative interviewing of a vulnerable suspect is a complex and difficult task. Current best practice advocates for the use of open questions in order to elicit a free recall. However, those with mental health conditions have limited cognitive abilities that relate to free recall and episodic memory, and there is emerging evidence that suggests open questions may not always be most suitable for the vulnerable interviewee. As such, the present study examined the impact of two different interview models (best practice v modified interview) on the amount and accuracy of investigation relevant information obtained within an experimental vulnerable ‘suspect’ sample. Participants engaged in two tasks; a minor transgression and a matched non-transgression. Each participant was then subject to either a best practice (containing largely open questions) or a modified interview (containing largely closed questions). Vulnerable participants provided a significantly higher and more accurate amount of investigation relevant information during the modified interview rather than the best practice interview. In addition, participants that have mental health conditions sought more clarifications during the best practice interviews. The type of interview did not impact upon the level of vulnerability displayed. Our findings challenge current best practice in that vulnerable participants performed worse in interviews containing more open questions than closed questions. These findings add to the emerging evidence base that vulnerable individuals may require an alternative method of questioning, including the use of closed questions as ‘scaffolding’ during an investigative interview
Forgetting having denied: The "amnesic" consequences of denial
The concept of denial has its roots in psychoanalysis. Denial has been assumed to be effective in blocking unwanted memories. In two experiments, we report that denial has unique consequences for remembering. In two experiments, participants viewed a video of a theft and half of the participants had to deny seeing certain details in the video whereas the other half had to tell the truth. One day later, all participants were given a source monitoring recognition or recall task. In these tasks, they were instructed to indicate (1) whether they could remember talking about certain details and (2) whether they could recollect seeing those details in the video. In both experiments, we found that denial made participants forget that they talked about these details while leaving memory for the video unaffected. This denial-induced forgetting was evident for both the source monitoring recognition and recall tests. Furthermore, when we asked participants after the experiment whether they could still not remember talking about these details, participants who had to deny were most likely to report that they forgot this. In contrast to a widely held belief, we show that denial does not impair memory for the experienced stimuli, but that it has a unique ability to undermine memory for what was talked about
Sexual Abuse-Current Medico-legal, Forensic and Psychiatric Aspects
Abstract
Violence against women and minors is a worldwide problem that has not yet been sufficiently acknowledged. There are many obstacles especially when sexual abuses have to be evaluated. These problems are present both when victims of sexual abuse are evaluated and when sex offenders are dealt with, especially when the offenders are juvenile sex offenders (JSO).
These issues give cause for great concern about prognosis, and the resulting psychosocial implications, and call for a special effort from the scientific community in identifying appropriate prevention and treatment methods.
This chapter is divided into two parts. The first part deals with the forensic and psychiatric features, such as diagnostic and therapeutic/rehabilitative strategies for JSO, while the second part analyzes the legal–medicine aspects related to rape/sexual assault in a European context
