Illegal alcoholic beverages are often introduced into market using cheap technical alcohol, which is contaminated by denatonium benzoate (Bitrex) of very small concentration. Bitrex is the most bitter chemical compound and has to be removed before alcohol consumption. The home‐made methods utilize sodium hypochlorite to disintegrate particles of denatonium benzoate in alcohol and to remove bitter taste before trading. In this experimental studies, we propose a novel method that detects in a fast way the remnants of denatonium benzoate in dubious alcohol samples by Raman spectroscopy. This method applies a portable Raman spectrometer of excitation wavelength 785 nm and utilizes the effect of surface‐enhanced Raman spectroscopy (SERS) to recognize the suspected alcoholic beverages. High effectiveness (over 98%) of YES/NO classification of the investigated samples was observed when the nonlinear algorithm support vector machine (SVM) was exploited at carefully adjusted detection parameters. The method can identify illicit alcohol within minutes.  相似文献

We present three studies examining the role of prior job experience in interviewing and interviewers' ability to learn open-ended questions during a training program. We predicted a negative relationship such that more experienced interviewers would perform worse after training than less experienced interviewers, and that (irrespective of baseline performance) the more experienced interviewers would improve the least during training. These predictions were made for two reasons. First, specific questions are commonly used in the workplace (i.e. open-ended questioning constitutes new learning). Second, experience in the use of specific questions potentially interferes with newly learned open-ended questions. Overall, our predictions were supported across different participant samples (including police officers specialized in child abuse investigation and social workers from the child protection area), time delays, and modes of training. The results highlight the need for investment in ongoing investigative interviewing training commencing early during professionals' careers, prior to the establishment of long-term habits in the use of specific questions.  相似文献

This case study involves the unexplained death of a previously healthy 30‐month‐old child. Reportedly, she was found unresponsive by her foster father following a 2‐hour nap. She was transported to the hospital and died in the emergency room of unknown causes. Blood drawn in the ER showed hemoglobin of 4.3 mg/dL. Postmortem skeletal survey, magnetic resonance imaging (MRI) of the brain, and retinal examinations were negative. The medical examiner assumed jurisdiction of the body. The autopsy showed massive retroperitoneal hemorrhage, transections of the abdominal aorta, and inferior vena cava, and complete tears of the anterior longitudinal ligament of the spine at C5/C6 and L1/L2 with diastases of the vertebral bodies at the corresponding intervertebral disk spaces. The case is believed to be extraordinary due to both the extent of injury that does not match the reported history and the mechanism of vertebral and vascular injuries.  相似文献

The over-representation of black children in US out of home care results from racial bias in placement decisions and a political choice to address startling rates of child poverty by investigating parents instead of tackling poverty's societal roots. The impact of state disruption and supervision of African American families is intensified when it is concentrated in inner-city neighbourhoods – the system's ‘racial geography.’ A small case study of a black neighbourhood in Chicago with high rates of out of home placement found profound effects on both family and community social relationships, as well as reliance on child protective services for financial assistance, linking surveillance of black families to the neoliberal shrinking of public programmes. The surveillance of African American women by the child welfare system is also intensified by these women's disproportionate involvement in the prison system. Acknowledging racial bias in child welfare reveals the need to radically transform the system from one that relies too much on punitive disruption of families to one that generously supports them.  相似文献

ABSTRACT

Family court and abuse professionals have long been polarized over the use of parental alienation claims to discredit a mother alleging that the father has been abusive or is unsafe for the children. This paper reports the findings from an empirical study of ten years of U.S. cases involving abuse and alienation claims. The findings confirm that mothers’ claims of abuse, especially child physical or sexual abuse, increase their risk of losing custody, and that fathers’ cross-claims of alienation virtually double that risk. Alienation’s impact is gender-specific; fathers alleging mothers are abusive are not similarly undermined when mothers cross-claim alienation. In non-abuse cases, however, the data suggest that alienation has a more gender-neutral impact. These nuanced findings may help abuse and alienation professionals find some common ground.  相似文献

Questions about when it is right for police forces to investigate alleged offences committed in the more or less distant past have become increasingly pressing. Recent widely publicized cases of child sexual abuse (CSA) and exploitation, sometimes involving high profile individuals, have illustrated the ethical, psychological, and forensic complexities of investigating non-recent child sexual abuse. Hannah Maslen and Colin Paine have developed the Oxford CSA Framework to assist police to weigh the various ethical considerations that militate for and against initiating a CSA investigation. While such a tool is to be welcomed, and while there is much that is helpful in Maslen and Paine's approach, we suggest that the Oxford CSA framework could be strengthened. Our first suggestion is to abandon a proposed distinction between a set of considerations that is said to generate a “presumption” in favor of investigation and other considerations that may supplement or oppose this presumption. Our second suggestion is to review the weightings applied to the considerations within the model, which lack clear justification and create problematic effects. Finally, we suggest that referring the Oxford CSA Framework to a panel with lived and professional experience of CSA could serve important procedural justice goals and enhance the Framework's recommendations.  相似文献

ABSTRACT

People who commit sexual offences are a heterogeneous group, with research suggesting that children and young people commit a large proportion of all sex offences, especially those committed against other children. This systematic review provides a synthesis of literature concerning the characteristics of children and adolescents who exhibit harmful sexual behaviour. There is a particular focus in this review on studies that examine the characteristics of children and young people exhibiting these behaviours within institutional and organisational settings or which take a situational and/or developmental approach to understanding sexually abusive behaviour. Using a developmental and life-course criminology lens, this review explores implications from the literature for the prevention and response to child sexual abuse, with a particular focus on institutional contexts where the perpetrators are children and adolescents.  相似文献

实践中对于非婚生育是否应当征收社会抚养费存在争议,而争议的背后是社会伦理道德、规范解读和理论适用等多方面因素共同作用的结果。非婚生育社会抚养费在行政收费原理下应围绕国家主体以概括量化的数字形式确定范围,避免婚姻状态对费用征收范围界定产生的影响。同时,在规范视角下,法律规定的“国家提倡一对夫妻生育两个子女”属于强制性义务,但不宜解读为禁止非婚生育行为。婚生与非婚生育本质上同属于生育行为,在同一体系内应当保证费用征收的同一性。因此,必须基于理论和规范的分析,方可界定非婚生育社会抚养费征收范围。  相似文献
