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.  相似文献

Detection of canines are well‐known to be valuable in the location of contraband, such as explosives or narcotics. More recently, canines have been trained and utilized in the detection of concealed mass storage devices that might contain evidence of illegal activity such as child pornography. To lay the analytical foundation for this detection work, research was carried out to determine the volatile organic compounds associated with mass storage devices (MSD) that could be used by trained canines for detection. Headspace analysis of a variety of electronic devices was performed using solid phase microextraction (SPME) with gas chromatography/mass spectrometry (GC/MS). Analyses found several volatile compounds common to SIM and SD cards, as well as USB drives, including 2‐propenenitrile, styrene, isophorone, hydroxycyclohexyl phenyl ketone, and 2‐furanmethanol, tetrahydro. Results indicated that mass storage devices do have a characteristic odor profile making detection with minimal false alerts feasible for trained canines.  相似文献

The dearth of studies investigating diagnostic stability among offenders, and diagnostic stability being important from the patient’s mental health perspective, as well as from a public health, training and research standpoint, highlights the need to evaluate lifetime stability of ICD-10 psychiatric diagnoses for offenders in community and prison settings. A case-linkage design linked a two-year population-based cohort of male-sentenced prisoners with a state-wide psychiatric register (23,742 psychiatric consultations). Four measures of diagnostic stability were calculated for each setting as well as across settings, for all offenders who received at least two psychiatric diagnoses. Temporal consistency was moderate for schizophrenia spectrum disorders and low for affective, anxiety and personality disorders, and was higher in prison setting than community settings. Diagnostic instability highlights that the course of mental illness and clinical features among offenders may genuinely vary over time, across community and prison settings and may lead to complexities regarding psychiatric care for this population  相似文献

Scholars of mass incarceration point to the 1970s as a pivotal turning point in U.S. penal history, marked by a shift toward more punitive policies and a consensus that “nothing works” in rehabilitating inmates. However, while there has been extensive research on changes in policy makers' rhetoric, sentencing policy, and incarceration rates, scholars know very little about changes in the actual practices of punishment and prisoner rehabilitation. Using nationally representative data for U.S. state prisons, this article demonstrates that there were no major changes in investments in specialized facilities, funding for inmate services–related staff, or program participation rates throughout the late 1970s and the 1980s. Not until the 1990s, more than a decade after the start of the punitive era, did patterns of inmate services change, as investments in programming switched from academic to reentry‐related programs. These findings suggest that there is a large gap between rhetoric and reality in the case of inmate services and that since the 1990s, inmate “rehabilitation” has increasingly become equated with reentry‐related life skills programs.  相似文献

The purpose of this article is to examine the attitudes and substance use behaviors of African American adolescents living in the Midwest. A baseline survey was administered to 463 African American teens between the ages of 11-19. The article examines the relationship between attitudes toward drugs and drug-using behavior in this African American sample. Drug use will be compared to national drug use norms established by the Youth Risk Behavior Surveillance Survey. Overall participants had fairly negative attitudes toward drugs. Sixty percent of the sample reported that they were committed to a drug-free life, 74% had made a decision to stay away from marijuana, 79% reported making a decision not to smoke cigarettes, and 71% reported they would not get drunk in the next year. Females were more likely to stay away from marijuana than males. In this current study there is cause for alarm; participants reported higher percentages of ever smoking cigarettes and marijuana than the Youth Risk Behavior Surveillance Survey. This study shows there is a need to provide substance abuse prevention programs for African American adolescents. Limitations and future directions are also discussed.  相似文献

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.  相似文献

This article is based on an ethnographic study of a cottage for violent offenders in one state's maximum-security training school. Staff members working in the cottage were the institution's front line in its attempts to hold the youth accountable for their crimes while also trying to resocialize and rehabilitate young men who were growing up with few conforming role models. As such, cottage staff members were put in the difficult position of juggling their roles as corrections officers, counselors, and surrogate parents. To effectively do their job, they had to find ways to balance the rhetoric of rehabilitation with the punitive reality of daily life in the institution. This article details the juvenile justice career paths of the staff members in the cottage and provides a sociological analysis of the roles, responsibilities, and interactions of the staff members with each other and with the young men in their care.  相似文献

This article explores the legal and psychological ramificationsarising from the exclusion of evidence of sexual violence duringthe Civil Defence Forces (CDF) case at the Special Court forSierra Leone. Using empirical findings from post-trial interviewsconducted with the ten victim-witnesses who were originallyto testify, we juxtapose what the Special Court allowed thewomen to say, and what the women themselves wanted to say. Froma legal perspective, we then critique the Trial Chamber's reasonsfor excluding the evidence and question the legal bases uponwhich the women were silenced, arguing that wider and widercircles of the women's experience were removed from the Court'srecords despite there being ample authority at an internationallevel to support inclusion. We further look at the genderedbiases in international criminal law and how expedience andefficiency usurped the significance of prosecuting crimes ofsexual violence in this instance. From a psychological perspective,we discuss the consequences that the act of silencing had forthe witnesses, and argue that a more emotionally sensitive understandingof the Court's notion of ‘protection’ is required.  相似文献

Hyperthermia is one of the main symptoms of the toxic MDMA effect. In a fatal intoxication, the premortal increase in body temperature may lead to a false assessment of the time of death. The problems of drug-induced hyperthermia faced by forensic pathologists and criminal investigators are discussed on the basis of a death from the autopsy material of the Berlin Institute of Legal Medicine (CCM).  相似文献

The analysis of motor oils has wide applications in the forensic science field from comparing lubricants transferred between an automobile and a victim or crime scene to differentiating the compositions of plastic explosives. In this study, 40 unused motor oils were analyzed and compared by high-temperature gas chromatography-mass spectrometry to determine the potential for oil individualization. Oil samples were also collected from the crankcase dipsticks of 30 cars. Twenty-six of these oils could be differentiated from each other based on visual comparisons of the unresolved envelope (baseline rise due to incomplete separation) and the resolved hydrocarbons in the raw total ion chromatograms (TICs) and smoothed TIC data. Four of these oils were analyzed as unknowns and were correctly related to the corresponding vehicle. The use of extracted ion profiles (EIPs) was explored as a means to further discriminate between the indistinct samples based on the polycyclic aromatic hydrocarbon (PAH) content. The research discussed in this paper demonstrated that differentiation of motor oils was possible by examining the TIC, smoothed TIC, and EIP data.  相似文献
