Quantification of Maxillary Dental Arcade Curvature and the Estimation of Biological Ancestry in Forensic Anthropology

Previous studies suggest that palate shape is a useful indicator of biological ancestry in human remains. This study evaluates interobserver error in ancestry estimation using palate shape and explores palate shape variation in Gullah (descendants of West Africans) and Seminole (Indigenous American) population samples using geometric morphometric analysis. Ten participants were asked to ascribe biological ancestry and shape to 28 dental casts based on a classification scheme employed in previous studies. The mean correct classification was 42.0%, indicating that the likelihood of assigning the correct ancestry is very poor and not significantly different from random assignment (p = 0.12). The accuracy analysis based on categorical classification of the casts was complemented by geometric morphometric analysis of nine 3D landmarks reflecting palate shape of 158 casts. Principal component analysis results show no difference between populations regarding palate shape, and cross‐validated discriminant function analysis correctly classified only 62.0% of the specimens. Combined, these results show that previous methods to estimate ancestry are inaccurate and that this inaccuracy is probably due to a lack of palate shape differences between groups, rather than limitation of the analytical method per se. Therefore, we recommend caution should be used when choosing to apply the analysis of palate shape in forensically relevant contexts.     

Introducing Computed Tomography Standards for Age Estimation of Modern Australian Subadults Using Postnatal Ossification Timings of Select Cranial and Cervical Sites,

Contemporary, population‐specific ossification timings of the cranium are lacking in current literature due to challenges in obtaining large repositories of documented subadult material, forcing Australian practitioners to rely on North American, arguably antiquated reference standards for age estimation. This study assessed the temporal pattern of ossification of the cranium and provides recalibrated probabilistic information for age estimation of modern Australian children. Fusion status of the occipital and frontal bones, atlas, and axis was scored using a modified two‐ to four‐tier system from cranial/cervical DICOM datasets of 585 children aged birth to 10 years. Transition analysis was applied to elucidate maximum‐likelihood estimates between consecutive fusion stages, in conjunction with Bayesian statistics to calculate credible intervals for age estimation. Results demonstrate significant sex differences in skeletal maturation (p < 0.05) and earlier timings in comparison with major literary sources, underscoring the requisite of updated standards for age estimation of modern individuals.     

The ‘right to be forgotten’ or the ‘principle that has been remembered’

The Court of Justice of the European Union (CJEU) has ruled on questions referred by a Spanish court relating to interpretation of the Data Protection Directive and its application to search engine activities. In a controversial judgment, the CJEU found that search engines are data controllers in respect of their search results; that European data protection law applies to their processing of the data of EU citizens, even where they process the relevant data outside the EU; and that a ‘right to be forgotten’ online applies to outdated and irrelevant data in search results unless there is a public interest in the data remaining available and even where the search results link to lawfully published content.     

Perceived altruism: a neglected factor in initial intervention

Perceived altruism, an attitude that clients may attribute to those who work with them, was examined in a qualitative and quantitative study about the impact of volunteers in drop-in centers for youth at risk in Israel. Data were collected by interviews, observations, case studies, and questionnaires. The results show that the volunteers' unique contribution affected the service as a whole. The beneficiaries knew that volunteers were servicing them, perceived volunteers as true altruists, were satisfied to the degree of preferring their services over that of paid workers, and were positively affected by the encounter with volunteering. A significant impact was that volunteers set a living example of the possibility of human goodness via personal encounters and demonstrated the existence of a responsive society with mutual, unconditional caring. These results exhibit practical implications for innovative interventions with youth at risk and illustrate the significance of the psychology of goodness.     

Parental Child Abduction in Singapore: The Experience of a Non-Convention Country

This article gives an exploratory picture of the landscape oninternational parental child abduction cases in a non-HagueConvention country, Singapore. It presents data and analyseson unpublished cases and materials in the past five years fromthe Singapore Family Court Registry (SFCR) and discusses theways in which the disputes are resolved (or unresolved) withoutthe machinery of the Hague Convention. It also examines thewelfare principle in the context of cross-border child abductionas well as how a non-Convention country can cooperate in theelimination of child abduction while applying the welfare principle.     

An outcome evaluation of the Methodist Home for Children’s value-based therapeutic environment model

Objectives

This study presents an outcome evaluation of the Value-Based Therapeutic Environment model, a multipurpose, cognitive–behavioral treatment approach for juvenile offenders.

Methods

Using a quasi-experimental design, the impact of VBTE treatment on recidivism is assessed for 258 youths, relative to a matched subsample of 258 comparison subjects.

Results

Results indicate that VBTE treatment is an effective intervention for reducing violent recidivism but has no significant effect on property, drug, or public order offenses. Consistent with past research, offender type moderates the impact of treatment. Specifically, 72.8 % of high-risk/need youth in the comparison group had reoffended within a 16-month follow-up period, compared to only 57.5 % of high-risk/need MHC youth, yet there were no significant differences between the treatment and comparison groups among low- and medium-risk/need juveniles. Moreover, the odds of a new violent charge were 49 % lower for high-risk/need MHC youth during the 12 months following MHC-discharge. Supplementary analysis indicates that VBTE participants also showed improvements on value- and skills-based behaviors related to self-image, goal orientation, honesty, empathy, decision-making, and personal development.

Conclusions

Findings of this study suggest that the VBTE model is a promising approach for the treatment of violent behavior among high-risk youth. Implications of the findings are discussed with regard to alternative treatment approaches for juvenile offenders.

     

Reflecting on 25 Years of Teaching Animal Law: Is it Time for an International Crime of Animal Ecocide?

2019 marked the 25th anniversary of the introduction of Animal Law to the law degree at Liverpool John Moores University. This article examines changes in the legal protection of animals during this time and the impact this will have on research and scholarship in the law relating to animals. We examine whether the overall international treatment of animals has improved and how far the approach to the Animal Law curriculum should be influenced by the growth in concerns around climate change. In this context, we examine the development of the law of ecocide and the extent to which it addresses concerns around animal welfare across the globe. We suggest that those involved in the development of Animal Law, ethics and policy might usefully engage in a new vision of ecocide, which incorporates a clearer notion of ‘animal ecocide’. This new approach would enhance the international and national focus on animals in their own right, would recognise increasing knowledge of animal sentience and would move our responsibilities to them beyond anthropocentric approaches to environmental protection. We argue that the inclusion of a more specific reference to animal ecocide would contribute to the development of Animal Law and would lead to an enhanced relationship between Animal Law and attempts to protect the environment.
