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

Abstract: The proper identification of illicit plants such as Papaver somniferum L (opium poppy) is important for law enforcement agencies. The identification of opium poppy was presently tested using 10 genetic markers that are universal for all plants or specific to a few poppy plants. The genetic distances of universal markers such as nuclear internal transcribed spacer (ITS), 18S rRNA, plastid rbcL, and trnL‐trnF intergenic spacer (IGS) of 14 species included in the Papaveraceae and Fumariaceae family were acquired by sequence comparisons. Both the ITS region and trnL‐trnF IGS showed high levels of interspecific divergence. Six Papaver genera‐specific markers were developed from coding regions involved in morphine biosynthesis. Three markers (TYDC, NCS, and BBE) produced amplicons only in opium poppy, providing a presence/absence test for opium poppy, while three additional markers (CYP80B1, SAT, and COR) were genus specific. These 10 markers might be useful for the forensic DNA analysis of opium poppy. 相似文献

A growing number of studies in criminal victimization had integrated the individual model and the context model to examine the dynamics of influences from the predictors at different levels. Only a few studies, however, had explored the impact of multilevel factors upon criminal victimization outside the U.S. context. Using the survey data gathered in Seoul, South Korea, the current study tested the applicability of the multilevel approach in criminal victimization to the Korean context. The results were mixed. At the macro level, poverty and community cohesion were positively associated with victimization by street crime and residential crime, respectively. Inconsistent with the findings in the U.S. studies, however, community cohesion increased the chance of residential crime victimization, and residential mobility was not significantly associated with criminal victimization. At the micro level, avoidance behaviors and target hardening efforts were associated with more criminal victimization, contrary to the proposition by opportunity theory. These unexpected findings could be explained by the unique social and cultural characteristics of Korean society. The unique contexts of modern Korean society as well as the limitation of the current study are discussed. 相似文献

The professional boundaries of practice for nurses and midwives are specifically addressed in professional codes of ethics and conduct, employer policies and guidelines and more frequently in the professional literature. There are many forms in which boundary violations and boundary crossings may present or circumstances in which they may occur. This column considers a recent case (involving a bequest to a registered nurse under a will) which came before the Queensland Nursing Tribunal. The decisions of the tribunal, the District Court and the Court of Appeal provide practical guidance to nurses and midwives on the importance of establishing and maintaining the professional boundaries essential to the therapeutic relationship with their patients and clients. 相似文献
