A New Approach of Juvenile Age Estimation using Measurements of the Ilium and Multivariate Adaptive Regression Splines (MARS) Models for Better Age Prediction

Juvenile age estimation methods used in forensic anthropology generally lack methodological consistency and/or statistical validity. Considering this, a standard approach using nonparametric Multivariate Adaptive Regression Splines (MARS) models were tested to predict age from iliac biometric variables of male and female juveniles from Marseilles, France, aged 0–12 years. Models using unidimensional (length and width) and bidimensional iliac data (module and surface) were constructed on a training sample of 176 individuals and validated on an independent test sample of 68 individuals. Results show that MARS prediction models using iliac width, module and area give overall better and statistically valid age estimates. These models integrate punctual nonlinearities of the relationship between age and osteometric variables. By constructing valid prediction intervals whose size increases with age, MARS models take into account the normal increase of individual variability. MARS models can qualify as a practical and standardized approach for juvenile age estimation.     

Regulation of donor conception and the "time to tell" campaign

The first jurisdictions in the world to introduce legislation regulating donor conception were Victoria (Australia) and Sweden in the 1980s. Under the Infertility (Medical Procedures) Act 1984 (Vic), donor-conceived people (aged 18 years and over), their parents (if children were under 18 years) and donors gained the right to apply for identifying information about each other. Information can only be given with the consent of each party. To date, over 3,500 donor-conceived children have been born in Victoria since the 1984 Victorian legislation was introduced (and enacted in 1988). The first 106 donor-conceived children under this legislation turned 18 in 2006 and many of them may not know that they are donor-conceived. The Infertility Treatment Authority, Victoria, conducted a public education campaign to provide information and support to people affected by the legislation. The campaign and services associated with donor registers have had a significant initial impact.     

A review of the role of radical feminist theories in the understanding of rape myth acceptance

Abstract

Research into rape myth acceptance (RMA) first emerged in the 1970s, when authors such as Brownmiller (1975) and Burt (1980) proposed that rape was a mechanism that allowed men to exert power over women and that the endorsement of rape myths justified this sexual dominance. These influential theories have meant that subsequent definitions of rape myths have failed to acknowledge male victims of serious sexual assault, despite an increase in prevalence rates. More recent research has attempted to explore RMA in relation to male victims, with results suggesting that men are more likely than women to endorse rape myths regarding male victims when the victim is assumed to be homosexual, or when the victim is heterosexual and the perpetrator is female. Brownmiller's theory is challenged and a more holistic view of the importance of sex-role traditionality is explored, while acknowledging the contribution of individual factors relating to the development of RMA.     

Factors associated with contact child sexual abuse in a sample of indecent image offenders

Abstract

This study explored a sample of 244 UK adult male offenders convicted of offences involving indecent images of children (IIOC): 120 had a previous contact child sexual offence (defined as dual offenders) and 124 had no evidence of an offence against a child (defined as non-contact offenders). Offender groups were compared regarding their socio-demographic characteristics, previous convictions and IIOC possession. Key discriminatory factors that differentiated dual offenders were: access to children, previous offence history, sexual grooming and possession of IIOC that depicts similar-aged victims. In contrast, non-contact offenders could be identified from their greater amount and wider range of IIOC possession. The results suggest a homology between Internet behaviours, IIOC possession and victim selection. Implications for law enforcement agencies are discussed in terms of assisting investigative prioritisation by identifying those most at risk of committing sexual abuse against children.     

Youths who sexually harm: A multivariate model of behaviour

Abstract

This study investigates the variations in behaviour displayed by young people who sexually harm, as previous research has shown that they are not a homogeneous sample. Three conceptually distinct sets of behaviour were hypothesized, relating to various modes of interaction between the young people with harmful sexual behaviour (HSB) and their victim, victim as object, victim as person and victim as vehicle. Thirty-three behaviours were drawn from an extensive review of the files of 300 youths who had sexually harmed. The pattern of co-occurrence of the presence or absence of these behaviours was revealed by a multidimensional scaling procedure, Smallest Space Analysis (SSA). The results provide empirical support for three distinct behavioural themes; 258 (86%) of the youths could be assigned to one dominant mode of interaction (victim as object, victim as person or victim as vehicle). The findings have implications for the ways in which practitioners differentiate between young people with HSB.     

Improving emergency management: A total quality management approach

We address the problem of managing emergencies in complex environments and examine the concepts of total quality management (TQM) as a means of increasing organisational capacity to reduce and/or respond to threatening events. The TQM approach initiates and integrates improvement in three fundamental areas of organisational design and operation: technical, organisational, and cultural. We apply this approach to the interactive environment of hazardous materials management and present an “action plan” for introducing TQM into community planning for risk reduction and response, focusing on the technical, organisational, and cultural components of the process. We present evidence of increased performance in reducing hazardous materials risk from field reports of communities that have adopted TQM practices. Finally, we conclude that TQM serves as a generative means of revitalising, renewing, and enabling community engagement in hazardous materials management.     

Classifying partner femicide

The heterogeneity of domestic violent men has long been established. However, research has failed to examine this phenomenon among men committing the most severe form of domestic violence. This study aims to use a multidimensional approach to empirically construct a classification system of men who are incarcerated for the murder of their female partner based on the Holtzworth-Munroe and Stuart (1994) typology. Ninety men who had been convicted and imprisoned for the murder of their female partner or spouse in England were identified from two prison samples. A content dictionary defining offense and offender characteristics associated with two dimensions of psychopathology and criminality was developed. These variables were extracted from institutional records via content analysis and analyzed for thematic structure using multidimensional scaling procedures. The resultant framework classified 80% (n = 72) of the sample into three subgroups of men characterized by (a) low criminality/low psychopathology (15%), (b) moderate-high criminality/ high psychopathology (36%), and (c) high criminality/low-moderate psychopathology (49%). The latter two groups are akin to Holtzworth-Munroe and Stuart's (1994) generally violent/antisocial and dysphoric/borderline offender, respectively. The implications for intervention, developing consensus in research methodology across the field, and examining typologies of domestic violent men prospectively are discussed.     

Morphometric criteria for sexing juvenile human skeletons using the ilium

Previous attempts to sex juvenile skeletons have focused on the application of qualitative or semi-quantitative techniques. This study applies a variety of geometric morphometric methods, including eigenshape analysis, to this problem. Six metric criteria for the ilia were tested with the aim of investigating previous ideas concerning sexually diagnostic characters. This study uses 25 ilia from juveniles of known age and sex from Christ Church, Spitalfields, London. Ninety-six percent of juvenile ilia were correctly identified as male or female using the shape of the greater sciatic notch. Identification accuracy is shown to improve with age for several criteria. Males were identified to a higher accuracy than females. Application of geometric techniques improves the understanding of the relationship between age, sex, and shape and the clarity with which these relationships can be quantified. Archaeological and forensic relevance of the results are discussed with recommendations for future application.
