Identifying failure mechanisms in skeletal tissue allows a deeper understanding of the effects of specific projectile impacts on bone. While ballistic trauma in flat bones is largely researched, knowledge of how long bones react to gunshot impacts is limited in the literature. The impacts of deforming ammunition appear to produce higher levels of fragmentation; however, these have not been studied in depth. This study compares the damage to femora bone by HP 0.357 and 9 mm projectiles constructed with both full and semi-metal jackets. Impact experiments were undertaken on a single-stage light gas gun involving the use of a high-speed video camera and full reconstruction of the bones to ascertain fracture patterns occurring in the femora. Higher degrees of fragmentation are likened to the presence of semi-jacketed HP projectiles than jacketed HP projectiles. The observations of external facing beveled edges are believed to be associated with the increased separation of the jacket and lead core of projectiles. Additionally, experimentation has shown that the amount of kinetic energy lost postimpact is likely related to the presence or the absence of a metal jacket on an HP projectile. The observed data, therefore, suggest that the composition, rather than the configuration, of a projectile affects the type and extent of the damage. 相似文献

There is currently no published empirical evidence‐base demonstrating 3D printing to be an accurate and reliable tool in forensic anthropology, despite 3D printed replicas being exhibited as demonstrative evidence in court. In this study, human bones (n = 3) scanned using computed tomography were reconstructed as virtual 3D models (n = 6), and 3D printed using six commercially available printers, with osteometric data recorded at each stage. Virtual models and 3D prints were on average accurate to the source bones, with mean differences from ?0.4 to 1.2 mm (?0.4% to 12.0%). Interobserver differences ranged from ?5.1 to 0.7 mm (?5.3% to 0.7%). Reconstruction and modeling parameters influenced accuracy, and prints produced using selective laser sintering (SLS) were most consistently accurate. This preliminary investigation into virtual modeling and 3D printer capability provides a novel insight into the accuracy of 3D printing osteological samples and begins to establish an evidence‐base for validating 3D printed bones as demonstrative evidence. 相似文献

Interest in the relationship between autism and violence has increased in recent years; however, no link has clearly been established between them. Researchers remain curious if autistic people with certain traits (e.g., a history of trauma) are at greater risk of violence than those individuals with autism alone. In this article, we detail two individuals with homicidal ideation (HI) admitted to inpatient psychiatric units who were found to have a diagnosis of autism without language impairment. These cases illustrate the need for mental health providers to consider autism in their differential diagnosis when evaluating an individual with HI. Broadly, we consider how an autistic individual could be susceptible to developing HI and explore treatments specific to autistic individuals that may be helpful in such cases. 相似文献

This article examines the impact of the Twentieth Congress of the Communist Party of the Soviet Union on the Communist Party of Australia (CPA). Specifically it focuses on the reverberations of Khrushchev's “secret speech” within the CPA leadership for the first six months of 1956. It argues that, in contrast to the received wisdom, the response of the leadership was characterised by confusion rather than consistency, division rather than unanimity. This had implications for CPA members as they struggled to come to terms with the line of the leadership and the authenticity or otherwise of the New York Times version of Khrushchev's speech. The words of [Khrushchev's] speech were like bullets, and each found its place in the hearts of the veteran Communists. Tears streamed down the faces of men and women who had spent forty or more years, their whole adult lives, in the movement […]. 1 相似文献

The validity and feasibility of using DNA collection cards in the field for preservation and analysis of Cannabis sativa genotypes were investigated using a highly specific hexanucleotide marker. Collection cards were submitted to the National Marijuana Initiative, which selectively trained and managed the collection of specific types of samples from a variety of participating agencies. Samples collected at seizure sites included fresh marijuana leaf samples, dried "dispensary" samples, U.S. border seizures, and hashish. Using a standardized PCR kit with custom-labeled oligonucleotide primers specific to marijuana, collection cards produced eight genotypes and 13 different alleles, extremely low baselines, and no cross-reactivity with control plant species. Results were produced from all sample types with the exception of hashish. Plant DNA collection cards represent an easily implementable method for the genetic identification and relatedness of C. sativa street and grow site-seized samples with applications for databasing and market disruption. 相似文献

Previous negotiation research has explored the interaction and communication between crisis negotiators and perpetrators.
A crisis negotiator attempts to resolve a critical incident through negotiation with an individual, or group of persons in
crisis. The purpose of this study was to establish the interpersonal style of crisis negotiators and complementarity of the
interpersonal interaction between them and forensic inpatients. Crisis negotiators, clinical workers and students (n = 90) used the Check List of Interpersonal Transactions-Revised (CLOIT-R) to identify interpersonal style, along with eight
vignettes detailing interpersonal styles. Crisis negotiators were most likely to have a friendly interpersonal style compared
to the other non-trained groups. Complementarity theory was not exclusively supported as submissive individuals did not show
optimistic judgments in working with dominant forensic inpatients and vice versa. Exploratory analysis revealed that dominant
crisis negotiators were optimistic in working with forensic inpatients with a dominant interpersonal style. This study provides
insight into the area of interpersonal complementarity of crisis negotiators and forensic inpatients. Whilst further research
is required, a potential new finding was established, with significant ‘similarity’ found when dominant crisis negotiators
are asked to work with dominant forensic inpatients. 相似文献

A large body of literature has been dedicated to understanding re-offending after release from prison - a phenomenon known as recidivism. A meta-analysis was conducted using fifty- seven published studies on actuarial predictors of both violent and nonviolent recidivism in men and women. The current analysis resulted in 127 effect sizes between violent recidivists and non-recidivists, and sixty-eight effect sizes between violent recidivists with nonviolent recidivists. Several variables (drug/alcohol use, age, and marriage) were predictive of recidivism. Gender differences were also observed. In men, increased violent criminal history was associated with increased violent recidivism. This effect was not true for women. In fact, longer sentences were predictive of violent re-offending in women and not men. Despite limited data on women, pursuing the predictors of recidivism in men and women independently demonstrated that gender differences exist, and supported the need for more data concerning the predictors of recidivism in women. 相似文献
