In forensic anthropology, age‐at‐death estimation typically requires the macroscopic assessment of the skeletal indicator and its association with a phase or score. High subjectivity and error are the recognized disadvantages of this approach, creating a need for alternative tools that enable the objective and mathematically robust assessment of true chronological age. We describe, here, three fully computational, quantitative shape analysis methods and a combinatory approach that make use of three‐dimensional laser scans of the pubic symphysis. We report a novel age‐related shape measure, focusing on the changes observed in the ventral margin curvature, and refine two former methods, whose measures capture the flatness of the symphyseal surface. We show how we can decrease age‐estimation error and improve prior results by combining these outline and surface measures in two multivariate regression models. The presented models produce objective age‐estimates that are comparable to current practices with root‐mean‐square‐errors between 13.7 and 16.5 years. 相似文献

ABSTRACTIndia is witnessing growing violence against women including horrific rapes even in major metropolitan areas that have attracted considerable media attention. Insecurity and physical threat to women is real and a major concern. Justice Verma Commission that examined the Delhi rape case has recommended several measures including changes in laws involving crimes against women, yet little has changed. In this paper we conduct a variety of qualitative and quantitative analyses using open source data to understand the nature and extent of crimes against women in India. Police records indeed suggest a growing escalation in serious crimes against women. The paper also critically examines the efforts of the police and others, particularly non-governmental groups to combat such crimes. A number of policy recommendations are made for prevention including comparative efforts in Korea where crimes against women are similarly serious. 相似文献

The career stage theory postulates that employees go through different career stages, and each career stage has different effects on various outcomes, such as job satisfaction. There has been empirical support for the career stage theory from other disciplines, but there has been limited research relating to this theory to corrections. To expand the literature, the current study examined whether different career stages were significant predictors of job satisfactions, while including the personal characteristics and the workplace place variables among Texas correctional officers. The results supported the career state theory: job satisfaction was highest during the entry stage (0–2 years), but was lowest during the second career stage (2–5 years). In career stages three (5–15 years) and four (16+ years), job satisfaction rose. Possible interventions that correctional administrators can undertake to encourage job satisfaction from their staff during the second career stage are discussed. 相似文献

This paper analyses and discusses arguments that emerge from a recent discussion about the proper assessment of the evidential value of correspondences observed between the characteristics of a crime stain and those of a sample from a suspect when (i) this latter individual is found as a result of a database search and (ii) remaining database members are excluded as potential sources (because of different analytical characteristics). Using a graphical probability approach (i.e., Bayesian networks), the paper here intends to clarify that there is no need to (i) introduce a correction factor equal to the size of the searched database (i.e., to reduce a likelihood ratio), nor to (ii) adopt a propositional level not directly related to the suspect matching the crime stain (i.e., a proposition of the kind 'some person in (outside) the database is the source of the crime stain' rather than 'the suspect (some other person) is the source of the crime stain'). The present research thus confirms existing literature on the topic that has repeatedly demonstrated that the latter two requirements (i) and (ii) should not be a cause of concern. 相似文献

Mistaken eyewitness identifications are believed to contribute to a preponderance of wrongful convictions, underscoring the
need to identify methods to help decrease the likelihood of false convictions based on eyewitness testimony. The present study
tested the hypothesis that providing jurors with first-hand experience with eyewitness identification procedures could help
further sensitize them to the limitations of eyewitness testimony. Eighty college students watched a videotaped mock trial
in which the prosecution’s sole evidence was eyewitness testimony. In a 2 × 2 randomized factorial design, we manipulated
whether participants heard expert psychological testimony (henceforth referred to as expert testimony) on the limitations of eyewitness identification and whether they experienced an eyewitness identification procedure. As
predicted, experiencing the eyewitness identification procedure had a significant impact on juror decisions, suggesting that
this procedure could further help reduce the likelihood of wrongful convictions. 相似文献

The roles of registered nurses, enrolled nurses, nurse practitioners and midwives in the administration of medications are subject to the legislation and regulation in their respective States and Territories in Australia. Underpinning this regulatory framework is a presumption that health professionals who come under the relevant legislation and regulations have attained the levels of competency, skill and knowledge consistent with professional standards and the protection of the public. This column considers the provisions of the Health (Drugs and Poisons) Regulation 1996 (Qld) addressing the administration of controlled and restricted drugs in light of a recent Queensland Civil and Administrative Tribunal decision. 相似文献

The climate of school classrooms, shaped by a combination of teacher practices and peer processes, is an important determinant for children's psychosocial functioning and is a primary factor affecting bullying and victimization. Given that there are relatively few theoretically-grounded and validated assessment tools designed to measure the social climate of classrooms, our research team developed an observation tool through participatory action research (PAR). This article details how the assessment tool was designed and preliminarily validated in 18 third-, fourth-, and fifth-grade classrooms in a large urban public school district. The goals of this study are to illustrate the feasibility of a PAR paradigm in measurement development, ascertain the psychometric properties of the assessment tool, and determine associations with different indices of classroom levels of relational and physical aggression. 相似文献

The aim of this paper is to examine the principles that New Labour has employed in its citizenship and multicultural policies in Britain, and to clarify theoretical locations as well as philosophical rationales of those principles. By deliberative multiculturalism, I mean a set of policies and discourses of New Labour about citizenship and multicultural issues, which emphasizes rational dialogue and mutual respect with firmly guaranteed political rights especially for minorities. New Labour tries to go beyond liberal and republican citizenship practice through enhancing deliberation, the origin of which goes back to the British tradition of parliamentary sovereignty. It also attempts to achieve a one-nation out of cultural cleavages, shifting its focus from redistribution with social rights to multicultural deliberation with political rights. I organize my discussion with a focus on the difference between two theoretical concepts: the relationship between cultural rights and individual equality, and the relationship between national boundaries and global belonging. In the concluding section, I explain three positive developments of New Labour's approach and also four limitations it has faced. 相似文献

The fetus is subjected to mechanical forces during labor and delivery, which may result in traumatic injuries. Such injuries include intracranial hemorrhage, spinal cord lesions, cephalhematoma, cranial or peripheral nerve palsies, intraabdominal organ rupture, or bony fractures. Risk for perinatal trauma and mortality is increased in primigravidas, multiple gestations, abnormal presentations, maternal-fetal disproportion, oligohydramnios, forceps or vacuum extractions, and internal version maneuvers. Very-low-birth-weight neonates (<1500 g) are at high risk due to ease of deformity of the cranium. Infants with certain congenital anomalies or pathologic processes that distort normal anatomy are also at increased risk, especially when a prenatal diagnosis is lacking. The authors present a case of a term gestation neonate who sustained a cervical spine dislocation fracture of C5-7, with subtotal transection of the spinal cord and resultant paralysis. The fetus was in vertex presentation, and a manual vaginal delivery was attempted. When the infant lodged in the birth canal following a difficult delivery of the head and arms, its enlarged abdomen was palpated, and the delivery was converted to an emergent cesarean section. The infant lived for 3 days and then expired due to neurologic complications of trauma sustained during the attempted vaginal delivery. Autopsy revealed a previously undiagnosed intraabdominal immature teratoma. The pathology of teratomas, the most common neonatal tumor and occasionally implicated in cases of birth trauma, will be addressed, followed by a review of the literature concerning birth trauma. 相似文献

Although unexpected natural deaths comprise a large proportion of the cases seen in the forensic setting, the investigation of these cases remains a unique challenge. Some cases are straightforward; however, others require special examination and dissections, as well as the use of special dissections and ancillary studies. For the forensic investigator to accurately assign a cause and manner of death, one must be aware of the differential diagnoses, common scenarios, and typical victim. The authors reviewed all forensic cases referred to the Forensic Section of the Medical University of South Carolina over a 15-year period from January 1989-December 2003. The number of natural deaths occurring in adults (age 18 years and older) was 6932, compared with the overall number of 13,227 cases. The natural deaths were then analyzed as to autopsy findings, cause of death, cardiac versus noncardiac, age, race, and gender. Current techniques, special dissections, and ancillary studies that can assist in the classification of these deaths in the forensic setting are reviewed. 相似文献
