Abstract: Ethylmorphine, an opiate that is partially metabolized to morphine, is a common ingredient in antitussive preparations. We present a case where a 10‐month‐old boy was administered ethylmorphine in the evening and found dead in bed the following morning. Postmortem toxicological analyses of heart blood by gas chromatography‐mass spectrometry and liquid chromatography‐mass spectrometry revealed the presence of ethylmorphine and morphine at concentrations of 0.17 μM (0.054 mg/L) and 0.090 μM (0.026 mg/L), respectively. CYP2D6 genotyping showed that the deceased had an extensive metabolizer genotype, signifying a “normal” capacity for metabolizing ethylmorphine to morphine. The autopsy report concluded that death was caused by a combination of opiate‐induced sedation and weakening of respiratory drive, a respiratory infection, and a sleeping position that could have impeded breathing. This is the first case report where the death of an infant has been linked to ethylmorphine ingestion.  相似文献

Few criminological theories have been applied to the study of stalking perpetration, and even fewer address the presence of underlying psychological mechanisms. Attachment theory describes the ways in which an individual with a chaotic family environment in childhood may develop feelings of insecurity that may lead to increased aggression and violent behavior in adolescence and adulthood. In this study, a sample of college students (N = 2,783) were queried on self-reported stalking behaviors and the revised Experiences in Close Relationships (ECR-R) measure of adult attachment. Stalkers scored significantly higher on the insecure-anxious scale of attachment and lower on insecure-avoidant scale. Other psychological variables (major/minor psychiatric diagnoses, depression, and anger-related issues) were also examined, with a history of anger-related diagnosis or treatment positively and significantly associated with stalking perpetration. Implications for theory development in stalking and future research directions are discussed.  相似文献

The Word Memory Test (WMT) is claimed to measure effort and to detect cognitive response bias. Archival data from n = 2526 cases referred in 2009–2016 for medicolegal assessment were analyzed. Each participant underwent a medical and a psychological examination including a cognitive test battery and several validity measures including the WMT. The WMT validity test scores do not approximately follow a normal distribution. Thus, parametric statistics for WMT validity scores may not be appropriate. WMT performance explains 0–20% of the variance in cognitive test performance. This is more than what substantial brain damage accounts for. The standard uniform cutoff indicating a ‘fail’ in all three WMT effort subtests (equal or less than 82.5% correct responses) seems not supported by the data. Taking into account the context of the testing, cutoffs may be chosen according to the desired sensitivity or specificity. ROC-statistics with modified Slick criteria as gold standard for malingering look alike for the three WMT effort subtests, with a AUC between 0.86 and 0.88. The WMT seems a good indicator of both effort and (Slick) malingering, however, little is gained by administering the entire test.  相似文献

The goals of Balanced and Restorative Justice (BARJ) are to hold juvenile offenders meaningfully accountable, hear and empower crime victims and engage communities both as stakeholders who have been negatively impacted and as advocates to make things right for the crime victim, offender, and community. This article examines how several Oregon juvenile justice agencies have put BARJ into action over the last 25 years, highlighting specific examples of how several agencies have made this the philosophical underpinning of their work. An overview of the philosophical principles, values, and goals that drive this approach is also discussed.  相似文献

Public school systems in America have come under scrutiny due to the harsh treatment of students by School Resource Officers (SROs). Incidents of armed, uniformed police in schools affecting physical arrests in American classrooms seem to be ever more frequent in news cycles, likely due to the ease of capturing these events on video via cell phones of bystanders. Of particular note, visceral reports of “heavy-handed” SROs reinforce a consistent narrative from some media outlets suggesting that the simple presence of these officers inside schools leads to student arrests for behaviors that can arguably be dealt with by the school administration in a reintegrative manner. The apparent lack of school discretion and the presence of strict zero tolerance policies are at the root of an issue that has been termed the “School to Prison Pipeline” by mass media. SROs are often the exclusive focus of this issue, typically as a symbol of a school’s dedication to strict enforcement of rigid rules.  相似文献

Triangular development cooperation (TriCo) is a relatively new form of technical cooperation (expert advice), which includes, besides the traditional actors of the donor and the receiver, a third country: the new provider. At first sight, OECD donors' engagement in TriCo cannot be explained by any of the traditional explanations for aid provision. On the one hand, donors pass on their strategically favourable position to the new providers, whereas on the other hand, from a practitioners' view, TriCo is not necessarily beneficial for receiving countries. Therefore, donors' participation in TriCo constitutes a stunning puzzle of international politics. An in-depth case study assesses why Germany has recently engaged in TriCo. Exploring this empirical riddle does not only contribute to understanding this specific cooperation modality, but it also reveals insights for the general study of international cooperation: emerging powers are changing the landscape of international relations.  相似文献

Previous research has examined elements of police performance impacting community policing and police-citizen relationships, but no study has considered the impact of police use of profanity during arrest on public rating of force. Police profanity may negatively bias police-citizen interactions, and this bias could shape later interactions with community members, impact the quality of police-community relations, or even result in public outcry over excessive use of force. The aim of this study was to determine whether officer use of profanity during arrest led to public perception of excessive force and to examine whether gender of the officer or subject affected this relation. Force was evaluated as more excessive when profanity was used, when the subject was a female, and when the officer was a female. Participants who rated force as excessive had significantly more negative attitudes about police and police use of force. These findings have direct implications for police training and suggest that if police avoid the use of profanity, this could result in more positive relationships with the public and fewer allegations of excessive force. Future researchers should further evaluate the nature and impact of gender biases against female police, as they may contribute to reduced opportunities, less frequent promotion, and reduced self-efficacy in female officers.  相似文献

ABSTRACT: Determination of the muzzle‐to‐target distance is often a critical factor in criminal and civil investigations involving firearms. However, seeing and recording gunshot residue patterns can be difficult if the victim's clothing is dark and/or bloodstained. Trostle reported the use of infrared film for the detection of burn patterns. However, only after the film is developed are the results visible and multiple exposures at different settings may be needed. The Video Spectral Comparator? 2000 (Foster & Freeman Ltd., Evesham, Worcestershire, U.K.) is an imaging instrument routinely used by forensic document examiners. Without use of specialized film could the VSC 2000 (at appropriate instrument settings) quickly, easily, and reliably provide instantaneous viewing, saving, and printing of gunshot residue patterns on dark and/or blood soaked clothing? At muzzle‐to‐target distances of 6, 12, and 18 in., test fires were made into five different types of dark clothing using eight different handguns of different calibers. Gunshot residues were detected for all eight calibers, and powder burn patterns were seen on dark clothing for all three target distances and calibers except 0.22 long rifle and 0.25 ACP. Bloodstains did not preclude the viewing of these patterns.  相似文献
