Cranial thickness in relation to age, sex and general body build in a Danish forensic sample

The cranial thickness was measured in 64 individuals (43 males, 21 females) autopsied at our institute. The thickness was measured by taking a biopsy with a trephine at four specific locations on the skull. Complete medical records and pathologic autopsy results were available. While none of the individuals had suffered from diseases affecting bone or bone metabolism as such, a large sub group consisted of individuals with a history of, and autopsy finds consistent with, chronic substance and alcohol abuse. There was no statistically significant difference in cranial thickness measures between this group and the rest of the material. Subsequent analyses failed to reveal any correlations between the cranial thickness and sex and age and height and weight of the individual. This is in accordance with most earlier studies, which likewise show no correlation, or only very faint trends, between cranial thickness and these parameters. This study, thus, adds to other studies showing that cranial thickness cannot be used in aging or sexing human remains. Likewise, in a forensic pathological setting, cranial thickness cannot be inferred from the individuals stature and build, which may be an issue in cases of interpersonal violence with cranial trauma.     

Persons with intellectual disabilities in the criminal justice system: review of issues

Although the vast majority of individuals with intellectual disabilities (ID) are law-abiding citizens, there is a small percentage with offending behaviour that is considered antisocial, socially inappropriate, or defined as illegal. It has long been recognised that individuals with ID or mental-health needs who break the law should be dealt with differently from the general population. There have been an increasing number of empirical studies in this area; however, these have been plagued by various definitional and methodological issues. Prevalence estimates of offenders with ID are complicated by diagnostic variations and inconsistencies in the criminal justice process. International studies have shown a large range, from 2% to 40%, depending on methodological approaches. The following review will highlight the salient issues including prevalence of offending, characteristics of offenders, vulnerabilities within the legal system, assessment, and a brief overview of intervention and treatment approaches.     

Effects of an Alibi Witness’s Relationship to the Defendant on Mock Jurors’ Judgments

Two studies tested the impact of an alibi witness’s relationship to a defendant on the perceived credibility of that witness. In the first study, 291 mock jurors estimated the frequency with which individuals would invent alibis, the frequency they themselves would do so, and the frequency of interpersonal contact among individuals of varying relationships. The degree of relationship between an alibi witness and a defendant remained a predictor of witness credibility when contact frequency was controlled. In the second study, 512 mock jurors were randomly assigned to case scenarios. Skepticism toward witnesses who are biologically or affinally related to a defendant was greater than skepticism toward a socially linked witness. Both studies supported predications from kinship theory and reciprocal altruism.     

An evaluation of determination of handedness using standard osteological measurements

Numerous studies have assessed side dominance assuming arm bones on the side of handedness will be larger, but concerns over sample size or replicability of measurements usually emerged. Attempting to improve upon these limitations, this investigation analyzes patterns of side difference for standard length and transverse dimensions of the scapula, clavicle, humerus, ulna, and radius for 137 individuals of known handedness. The results showed that with few exceptions, the right side of the skeleton was consistently larger in most individuals regardless of side dominance. Combinations of other measurements previously suggested to be indicative of handedness as well as the use of discriminant analysis also failed to provide reliable estimators. These findings are likely related to the fact that activities of modern individuals are generally not sufficiently unilateral in their stresses to cause asymmetrical development in the arm bones. Therefore, it is recommended that other means be developed to assess side dominance.     

What is the prevalence of abuse in the deaf/hard of hearing population?

It is thought that deaf or hard of hearing individuals are at greater risk of abuse than the hearing population. The purpose of this paper is to systematically examine and integrate existing literature to determine the prevalence rates of neglect, emotional, physical and sexual abuse and intimate partner violence (IPV). A set of inclusion and exclusion criteria was determined. Following this a comprehensive search of numerous databases was conducted. Fourteen studies met the inclusion criteria. Eight studies reviewed the prevalence of sexual abuse, seven reviewed physical abuse, five reviewed emotional abuse, four reviewed neglect and six examined IPV. This exceeds 14 as numerous studies examined multiple types of abuse. Quality assessment indicated 12 studies were of ‘moderate’ quality and the remaining two were rated ‘good’ quality. Issues with similar samples, a tendency towards young, educated women within the IPV data, and small samples suggest caution is to be used when interpreting their results. The reliance on written measures and the absence of an interpreter or translation of materials in some studies further complicates the results. All types of abuse were found to be more prevalent within the deaf and hard of hearing population compared to the hearing population.     

When legal rights are not a reality: do individuals know their rights and how can we tell?

Public knowledge of rights has been the subject of a number of empirical enquiries over the last decade. In England and Wales, knowledge of rights and its relationship with an individual's capacity to ‘self-help’ and ‘self-represent’ when faced with a civil justice problem has become the subject of renewed attention following changes to legal aid which, from March 2013, will see the availability of legal advice and representation dramatically reduced. Previous studies focusing on public knowledge of rights in this (and other) jurisdictions have illustrated a lack of knowledge amongst the general population and more specifically, a widespread tendency of individuals to assume that the law aligns with their own moral, ethical or social attitudes. However, many of these studies have also suffered from methodological shortcomings. In attempting to address some of these shortcomings this study uses an open-ended format to ask individuals with one or one or more civil or social justice problems to describe their rights/legal position. We find that whilst an open-ended question approach to exploring knowledge of rights yields insight not acquired by other formats, its utility is constrained by difficulty reconciling articulation and actual knowledge of rights. We discuss the implications of these findings as they relate to the development of future research in the field of family and social welfare law, Public Legal Education (PLE) and access to justice post-March 2013.     

Testing the validity of population-specific sex estimation equations: An evaluation based on talus and patella measurements

Sex estimation is essential for forensic scientists to identify human skeletal remains. However, the most sexually dimorphic elements like pelvis or skull are not always assessable. Osteometric analyses have proven useful in sex estimation, but also to be population specific. The main purpose of this study was to test the validity of contemporary Greek and Spanish discriminant functions for the talus and the patella, respectively, on a Swiss skeletal sample and to quantify the utility of the measurements as a novel approach in osteometric sex assessment.Four talus and three patella measurements on dry bone were obtained from 234 individuals of the modern cemetery SIMON Identified Skeletal Collection. The previously derived discriminant functions were applied, accuracies determined, the utility of the different measurements was assessed and new multivariable equations constructed.Accuracies varied between 67% and 86% for talus and 63% and 84% for patella, similar to those reported by the original studies. Multivariable equations should be preferred over equations based on single measurements and combining the most significant measurements rather than using several variables obtained the best possible accuracy. The new discriminant functions did not provide a substantial improvement to the original ones. The overall utility of talus and patella is limited, allowing sex estimation with sufficient certainty only in a small proportion of individuals.Discriminant functions developed in contemporary Greek or Spanish populations are in principle applicable also to Swiss contemporary populations. We recommend that at present existent studies of this type should be validated and tested rather than developing new formulas.     

Re-examination of the Controversial Coexistence of Traumatic Brain Injury and Posttraumatic Stress Disorder: Misdiagnosis and Self-Report Measures

The coexistence of traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) remains a controversial issue in the literature. To address this controversy, we focused primarily on the civilian-related literature of TBI and PTSD. Some investigators have argued that individuals who had been rendered unconscious or suffered amnesia due to a TBI are unable to develop PTSD because they would be unable to consciously experience the symptoms of fear, helplessness, and horror associated with the development of PTSD. Other investigators have reported that individuals who sustain TBI, regardless of its severity, can develop PTSD even in the context of prolonged unconsciousness. A careful review of the methodologies employed in these studies reveals that investigators who relied on clinical interviews of TBI patients to diagnose PTSD found little or no evidence of PTSD. In contrast, investigators who relied on PTSD questionnaires to diagnose PTSD found considerable evidence of PTSD. Further analysis revealed that many of the TBI patients who were initially diagnosed with PTSD according to self-report questionnaires did not meet the diagnostic criteria for PTSD upon completion of a clinical interview. In particular, patients with severe TBI were often misdiagnosed with PTSD. A number of investigators found that many of the severe TBI patients failed to follow the questionnaire instructions and erroneously endorsed PTSD symptoms because of their cognitive difficulties. Because PTSD questionnaires are not designed to discriminate between PTSD and TBI symptoms or determine whether a patient's responses are accurate or exaggerated, studies that rely on self-report questionnaires to evaluate PTSD in TBI patients are at risk of misdiagnosing PTSD. Further research should evaluate the degree to which misdiagnosis of PTSD occurs in individuals who have sustained mild TBI.     

Pulp volume quantification methods in cone-beam computed tomography for age estimation: A critical review and meta-analysis

The secondary dentin deposition that occurs after the tooth formation process results in a decrease in pulp cavity volume in adolescents and adults. The purpose of this critical review was to correlate pulpal and/or dental volume on cone-beam computed tomography (CBCT) with chronological age approximation. A subobjective was to investigate which methodology and CBCT technical parameters would be most appropriate to evaluate this correlation. This critical review followed the PRISMA guidelines, and it was conducted by a search through PubMed, Embase, SciELO, Scopus, Web of Science, Cochrane Library databases, as well as gray literature. Primary studies that used pulp volume, or pulp chamber to tooth volume ratio measured using CBCT were included. Seven hundred and eight indexed and 31 non-indexed records were identified. A qualitative analysis was performed including 25 selected studies with a total of 5100 individuals, age ranging from 8 to 87 years without sex predilection. The most used method was pulp volume/tooth volume. CBCT voxel size ranged between 0.09 and 0.5. Manual segmentation associated with threshold algorithms was used in most of the studies. Correlation between the pulp volume/tooth volume ratio was moderate: −0.66 for the upper central incisors, −0.59 for upper canines and −0.56 for lower canines. High heterogeneity was observed among the studies. It is concluded that pulp volume should be used with caution in age estimation. Evidence supports the preferable use of upper incisors with pulp volume/tooth volume ratio for age estimation. There is not enough evidence that voxel size interferes in age estimation by pulp volume.     

Initiatives that Counter Violent Radicalization but are Perceived as Suitable by Targeted Communities

To redress the scourge of violent extremism, an array of policies, programs, and practices have been implemented. Yet, these initiatives could sometimes conflict with the preferences of individuals who may be susceptible to radicalization. To illustrate, some initiatives might challenge the values of these individuals. The degree to which these individuals feel significant or important might thus decrease—a decrease that has been shown to rouse the pursuit of violent radicalization. To prevent this complication, two studies were designed to uncover programs, policies, or practices that align to the preferences of people who may be more susceptible than average to violent radicalization. In Study 1, three individuals who had been charged with crimes related to terrorism, but had since relinquished extremism, were asked to suggest initiatives they feel could prevent violent radicalization in Australian Muslims. Similarly, in the second study, young Australian Muslim adults who rejected extremist ideologies were asked the same question. The participants advocated initiatives that foster tolerance towards diverse perspectives, inspire individuals to trust their values and intuition, encourage civic engagement, improve the credibility of imams, and enable people to derive strength from their community. A review of previous literature indicates that many of these initiatives might not only resonate with the preferences of individuals who may be vulnerable to violent extremism but could also foster a sense of significance and meaning in life—an experience that tends to prevent radicalization.     

A Life Course Analysis of Homeless Shelter Use among the Formerly Incarcerated

Prior work finds that the formerly incarcerated are at an elevated risk of homelessness. However, studies disagree regarding how these individuals experience homelessness; quantitative research emphasizes homelessness as a temporary obstacle experienced shortly after release, yet ethnographic work suggests that formerly incarcerated individuals experience frequent and/or lengthy bouts and are at risk long after release. Drawing on the life course perspective and nearly eight years of administrative records post release, this study examines patterns and correlates of homeless shelter use in a cohort of individuals released from prison. The results suggest that both immediate and delayed shelter use exist. Although the risk is highest soon after release, approximately half of individuals who used shelters experienced their first spell more than two years after release. Moreover, shelter use spells were prolonged and repeated. Findings also highlight the influence of cumulative disadvantage in understanding who is most at risk for shelter use.     

Lessons from Morality-Based Social Identity: The Power of Outgroup “Hate,” Not Just Ingroup “Love”

Based on the unique features of morality, we suggest that group memberships rooted in moral convictions are a special classification of inherently threatening social groups in which outgroup “hate” naturally occurs with ingroup “love.” Three studies explored emotional reactions to ingroups and outgroups by individuals whose group memberships were either morality-based or non-morality-based. Results of each study indicated that individuals in morality-based groups reported less positive ingroup emotions and more negative outgroup emotions and threat than did those in non-morality-based groups. Additionally, strength of morality-based identification was predicted by attitudes about both the ingroup and the outgroup, but only attitudes about the ingroup predicted identification for non-morality-based groups. Together, these studies suggest a necessary interdependence of ingroup positivity and outgroup negativity for social groups based in morality. We conclude that negative outgroup-related emotions may be just as important as positive ingroup-related emotions for social identification based on moral convictions.     

Discovery of decomposed and mummified corpses in the domestic setting--a marker of social isolation?

Mass media reports attribute the occurrence of decomposed or mummified corpses in a domestic setting mainly to an increasing social isolation of elderly people. Not much is known about the demographic and medical conditions under which individuals are found months or even years after death in their homes. For this study, autopsy reports of individuals found dead and mummified or decomposed between 1993 and 1997 with those from 1963 to 1967 were retrospectively analyzed. Between 1993 and 1997, a total number of 320 individuals were found decomposed at home compared to 412 such cases between 1963 and 1967. The proportion of individuals older than 64 years was significantly higher during the 1990s study period. Furthermore, the proportion of deaths attributable to natural causes was significantly lower during the 1990s, whereas the rate of suicides was nearly three times higher.     

Performing Arts Review: Statement of Scope and Purposes

Recent research on arts and cultural audiences has attempted to go beyond the traditional social science surveys that assess attitudes or attendance to capture an understanding of how audiences actually experience the arts and what benefits or impacts those experiences provide. The study reported here contributes to this growing body of research by presenting in-depth case studies of four individuals and their chosen cultural experiences at various times through their lives. The authors used Dervin's Sense-Making Methodology to guide the informants through highly structured but open-ended interviews designed to prompt self-reflection and elaboration of what each experience meant to them. Informants were selected from a larger database because of the richness of their interviews and the insight these interviews offer to the understanding of people's engagements with culture. By considering multiple cultural experiences for each informant, it was possible to gain a clearer sense of the context in which these experiences took place and how informants were impacted personally. In addition, the case studies showed how informants' respective struggles with personal and identity issues moved with them across their cultural experiences.     

Deciphering the riddle of human deceit detection: groups comprising a higher number of anxious people are better at distinguishing lies from truths

Are groups superior to individuals in detecting lies, and are there certain personality traits that significantly contribute to a collective lie-detecting capability? In the current research, we compared the ability of small groups to detect deception compared with individuals, and further examined whether small groups comprising more members high in attachment anxiety would show superior performance in detecting deceit. To this end, we asked 233 participants (40 groups and 113 individuals) to watch a series of clips showing a person making either truthful or untruthful statements, and then decide whether the speaker was honest or dishonest. Results confirmed our expectations and showed superior deceit-detection abilities in small groups, and that this ability was proportionate to the number of people high in attachment anxiety in the group. These results are discussed from the perspective of social defense theory, and the utility of diverse social groups in coping with diverse threats.     

用ELISA法进行AB型体液（斑）与A型、B型混和体液（斑）的血型测定和鉴别

在法医物证检案工作中,经常会遇到ABO型血型的判定,一般通过吸收试验、解离试验、以及混和凝集试验就能够进行分型.但在实际工作中,遇到的检材多数并非单一的体液,而是两种或者两种以上体液的混和斑.特别是强奸案的鉴定,阴道内提取的检材常常是由男性精液和女性阴道分泌物的混合物,要从混和斑中判断各自的血型,目前仍较困难.国内外许多学者都进行了有关的实验,试图
