Dental Age Estimation: A Test of the Reliability of Correctly Identifying a Subject Over 18 Years of Age Using the Gold Standard of Chronological Age as the Comparator 下载免费PDF全文
Victoria S. Lucas Ph.D. Manoharan Andiappan M.Sc. Fraser McDonald Ph.D. Graham Roberts M.D.S. 《Journal of forensic sciences》2016,61(5):1238-1243
This study was designed to test the reliability of using the third molars to demarcate between child and adult status. A total of 2000 dental panoramic tomographs were used for assessment of the calculated age using the 8‐stage system of tooth development and applied to all four third molars. The LL8 was also assessed using this 8‐stage system. For each tooth development stage, the Normal distribution and percentile summary data were estimated. The calculated dental age compared with the chronological age was statistically significantly different (p < 0.001) for both females and males giving underestimates of the true age. Comparison of single tooth dental age and chronological age was only slightly different. The most important finding is that the assignment to above or below the 18‐year threshold, in the age range 17 years to 19 years, could be wrong on up to 50% of occasions. 相似文献

Forensic anthropologists are more often turning to nondestructive methods to assist with skeletal analyses, specifically for trace elemental analyses. Portable XRF (pXRF) instruments are versatile and are able to be used in diverse settings or for specimens of a shape and size that cannot be accommodated by laboratory‐based instruments. Use of XRF requires knowledge of analysis parameters such as X‐ray penetration and exit depth. Analysis depth was determined by examining pure elements through known thicknesses of equine bone slices. Correlation between the element's X‐ray emission energy and the depth of reading was observed. Bone surfaces from a small unknown historic cemetery were analyzed before and after sanding of the periosteal surface to observe possible changes in XRF readings based on potential diagenesis. Results validate the pXRF device as a powerful and convenient instrument for nondestructive analysis, while highlighting limitations and considerations for the analysis of osseous materials. 相似文献

Opium is the raw material for the production of heroin, and the characterization of opium seizures through laboratory analysis is a valuable tool for law enforcement agencies to trace clandestine opium production and trafficking. In this work, a method for opium profiling based on the relative content of five principal and 14 minor opium alkaloids was developed and validated. UPLC‐Q‐TOF was adopted in alkaloid analysis for its high selectivity and sensitivity, which facilitated the sample preparation and testing. The authentic sample set consisted of 100 “Myanmar” and 45 “Afghanistan” opium seizures; based on the data set of the 19 alkaloid variables in them, a partial least squares discriminant analysis classification model was successfully achieved. Minor alkaloids were found to be vitally important for opium profiling, although combined use of both principal and minor alkaloids resulted in the best geographical classification result. The developed method realized a simple and accurate way to differentiate opium from Myanmar and Afghanistan, which may find wide application in forensic laboratories. 相似文献

ABSTRACTDepending on definitions, dynamic risk factors and desistance are either highly intertwined or aligned with distinctly separate paradigms. This paper describes and critiques each concept, and then reviews research on how they may be linked, including some preliminary findings from a longitudinal study of the early phases of desistance in high-risk offenders. I argue that seeking to understand how reductions in dynamic risk work together with the development of the psychological components of desistance will shed the most light on how offenders move from persistence to the maintenance of desistance. 相似文献

Probation officers have large caseloads with high levels of psychiatric morbidity but receive minimal training in recognising/managing mental health problems. In the UK, there is no national screening procedure for mental illness among offenders that is considered effective. This study’s aim was to develop a screening system for mental/personality disorders using the Offender Assessment System. Seven screens for mental disorder were developed using items from assessments on 574 prisoners: alcohol misuse, drug dependence, antisocial personality disorder, psychopathy, learning difficulties, psychosis and severe mood disturbance. Internal validation showed that the screens performed well across accuracy estimates. Prevalence of mental disorders identified with the screens in test and validation samples was similar. However, the psychopathy and severe mood disturbance screens may be more effective in screening for true negatives. The screens are an economical method for prioritising mental health needs of the UK prison and probation population using routinely collected data. 相似文献

This article recommends a modification of the child interview and observational components of the conventional child custody evaluation. By scheduling these events in back‐to‐back sequence, the evaluator adds critical process‐oriented data to familiar content‐oriented data. These additional data include at least eight landmark separation, reunion, and transition events valuable to understanding the dynamic family system. The benefits of this protocol are discussed in terms of the ecological validity of available data, reduced evaluation time and costs, and research. Limitations are discussed relevant to questions of sampling bias, fatigue and sequence effects, and practical dilemmas that arise when evaluating families with many children. 相似文献

We report on a sample of 90 child custody evaluators in the United States, who completed an online questionnaire on their attitudes and beliefs in child custody relocation cases. Findings indicated that the vast majority of participants relied on relevant professional literature and utilized a relocation risk assessment forensic model. Participants found many risk, protective, and specific relocation factors important, but the triad of past parental involvement, support for the other parent, and child's age were afforded the most importance. Participants also reported that the moving parents sought relocation for educational/vocational reasons, to receive support of their extended family, or to remarry, while the nonmoving party most commonly opposed relocation due to fears of interference/damage to the nonmoving parent–child relationship, restrictive gatekeeping, and alienation. A common trend among participants was concerns over the possible detrimental impact of any relocation on the nonmoving parent–child relationship and quality of co‐parenting. The vast majority of participants reported that they made specific recommendations to the court about relocation, and the court agreed with their recommendation the overwhelming majority of the time. We discuss Implications of the findings as well as areas needing further research. 相似文献

Officer‐involved domestic violence (OIDV) is a national problem, with police officer families having higher rates of domestic violence than non–police officer families. OIDV is also an underresearched problem with few studies or proposed solutions. Many victims of OIDV do not report their abuse precisely because their abuser is a police officer, whom they fear is in a unique position to protect him/herself from any legal consequences. Often, OIDV complaints are not investigated properly in a nonbiased manner. While a handful of police agencies around the country have developed specific policies and procedures to deal with OIDV, Washington State has enacted legislation that requires its police agencies to adopt OIDV‐specific policies. The International Associations of Chiefs of Police (IACP), an organization that addresses various issues confronting law enforcement, has also developed a model policy on OIDV. This Note proposes that, in light of the Washington legislation and the model policy proposed by the IACP, each state should enact a statute that requires its police agencies to develop policies on OIDV. This Note also outlines a specific set of procedures that such statutes should, at a minimum, require its police agencies to adopt, ranging from educating police officers on domestic violence to developing guidelines on responding to and investigating OIDV complaints. 相似文献

The Hennepin County Co‐Parent Court Project was a 3‐year demonstration project for unmarried co‐parents. The goal of the project was to remove barriers to co‐parenting in low‐income, unmarried parents. The Co‐Parent Court Project encompassed a number of services, including educational workshops, individual case management, parenting plans, legal mediation, and, if needed, supports and treatment for domestic violence. There are published articles that highlight the participant outcomes of the Co‐Parent Project. This article, however, focuses on the background for why this project was developed, components of this project, and lessons learned from implementation. 相似文献
