The international prevalence of “legal high” drugs necessitates the development of a method for their detection and identification. Herein, we describe the development and validation of a tetraplex multiplex real‐time polymerase chain reaction (PCR) assay used to simultaneously identify morning glory, jimson weed, Hawaiian woodrose, and marijuana detected by high‐resolution melt using LCGreen Plus®. The PCR assay was evaluated based on the following: (i) specificity and selectivity—primers were tested on DNA extracted from 30 species and simulated forensic samples, (ii) sensitivity—serial dilutions of the target DNA were prepared, and (iii) reproducibility and reliability—sample replicates were tested and remelted on different days. The assay is ideal for cases in which inexpensive assays are needed to quickly detect and identify trace biological material present on drug paraphernalia that is too compromised for botanical microscopic identification and for which analysts are unfamiliar with the morphology of the emerging “legal high” species.  相似文献

Much has been written on the imperative of intersectionality within the fight for women’s equality and in efforts to end gender-based violence. However, data continues to show that women and LGBTQ people of color experience heightened and more severe instances of both state and interpersonal violence. What lessons can domestic violence and sexual assault advocates and researchers learn from intersectional theory and frameworks to help reduce instances of violence, reduce barriers in accessing resources and create safety nets for communities? This paper seeks to explore the roots of historical violence against communities of color, the current trends in anti-violence research and service provision and strategies for engaging in intersectional community based research.  相似文献

Pre-hearing conferences are a form of alternative dispute resolution that have been implemented into the child welfare court process. Montana recently piloted a pre-hearing conference model to occur before the first hearing on the case. The goal of the pilot was to increase discussion and resolution of contested visitation, placement, and service issues and to better engage parents in the process. Data were collected across multiple years to explore the effectiveness of the pilot in improving outcomes for children and families. Analysis of the data revealed a positive relationship between program implementation and timelier permanency. Parents who attend and have higher levels of participation in the pre-hearing conference are also more likely to reunify.  相似文献

Cities across the U.S. have turned to summer youth employment programs (SYEPs) to improve the behavioral, economic, and academic outcomes of inner‐city youth. This paper evaluates the impact of the Boston Summer Youth Employment Program using both experimental and non‐experimental variation. Similar to previous studies of summer jobs programs in other cities, I make use of an embedded randomized controlled trial and find that the program reduces violent crime by 35 percent, as measured by the number of arraignments from administrative records during the 17 months after participation. In contrast to prior work, I also find a similar reduction in arraignments for property crimes (?29 percent). This study also provides exploratory evidence on the mechanisms driving these reductions in crime using self‐reported responses of participants from a pre‐/post‐program survey. The results provide suggestive evidence that the beneficial impacts on violent and property crime are largely driven by improved conflict resolution skills versus other factors that would increase the opportunity cost of crime. These findings give researchers some insights into the behavioral changes that occur during the program while also providing a look inside the “black box” as to how SYEPs affect youth outcomes in the long run.  相似文献

Mediation, facilitation, and other alternative dispute resolution (ADR) techniques are being used in federal agencies, state and local governments, private-sector organizations, and among private citizens in an effort to prevent and resolve disputes in a timely, cost-effective, and less adversarial manner. The U.S. Environmental Protection Agency (EPA), one of the pioneers in the application of ADR processes and techniques to public policy disputes, recently announced that it plans to in-crease the use of ADR techniques and practices across all agency programs. This article reports the results of a four-part evaluation of the use of ADR in enforcement actions at the EPA during the last two decades. Funded by the Hewlett Foundation, this effort utilized in-depth telephone interviews, government statistics, and archival records. The four groups interviewed were EPA's alternative dispute resolution specialists, potentially responsible parties (defendants) to EPA enforcement lawsuits, mediators and facilitators to EPA cases, and agency enforcement attorneys who had participated in agency enforcement ADR processes. Concluding that there are generally high levels of satisfaction with the EPA's enforcement ADR program, this article examines the sources of obstacles and assistance to ADR efforts at the EPA, suggests ways in which the EPA might improve its ADR programs, and draws lessons from the EPA's experiences that may be helpful to other public programs or organizations.  相似文献

Recent research has demonstrated that burglary clusters in space and time, resulting in temporal changes in crime hotspot patterns. Offender foraging behavior would yield the observed pattern. The offender as forager hypothesis is tested by analyzing patterns in two types of acquisitive crime, burglary and theft from motor vehicle (TFMV). Using a technique developed to detect disease contagion confirms that both crime types cluster in space and time as predicted, but that the space–time clustering of burglary is generally independent of that for TFMV. Police detections indicate that crimes of the same type occurring closest to each other in space and time are those most likely to be cleared to the same offender(s), as predicted. The implications of the findings for crime forecasting and crime linkage are discussed.

Purpose. The goal of the current study was to examine psychopathy and indirect measures of deception detection. Methods. Undergraduate students (N=444) viewed video clips of adult male offenders telling true and false stories about crimes. For each story, participants rated indirect measures of deception (thinking hard, nervousness, emotional arousal, and attempting to control behaviour) and credibility. Participants also chose the story they believed to be true and rated the confidence in their decision. Offenders were rated on the psychopathy checklist – revised. Results. Consistent with past research, deception detection accuracy was at chance level and unrelated to confidence. Ratings on indirect measures by undergraduates did not distinguish true and false statements in offenders. Psychopathic offenders were less successful at deception than non‐psychopathic offenders. Psychopathic traits were associated with lower perceived credibility during deception and ratings of thinking harder while lying. Conclusions. The results suggest that indirect measures of deception detection may be less useful in offender samples. Further, the findings are consistent with the general inability of psychopathic offenders to demonstrate superior deception skills in empirical studies. Indirect measures of deception uniquely related to psychopathic traits offer new insight into the relationship between psychopathy and deception.  相似文献

A blind quality control (QC) program was successfully developed and implemented in the Toxicology, Seized Drugs, Firearms, Latent Prints (Processing and Comparison), Forensic Biology, and Multimedia (Digital and Audio/Video) sections at the Houston Forensic Science Center (HFSC). The program was put into practice based on recommendations set forth in the 2009 National Academy of Sciences report and is conducted in addition to accreditation required annual proficiency tests. The blind QC program allows HFSC to test its entire quality management system and provides a real-time assessment of the laboratory’s proficiency. To ensure the blind QC cases mimicked real casework, the workflow for each forensic discipline and their evidence submission processes were assessed prior to implementation. Samples are created and submitted by the HFSC Quality Division to whom the expected answer is known. Results from 2015 to 2018 show that of the 973 blind samples submitted, 901 were completed, and only 51 were discovered by analysts as being blind QC cases. Implementation data suggests that this type of program can be employed at other forensic laboratories.  相似文献

Currently, aluminum stub with carbon adhesive devices are used to collect inorganic gunshot residues (GSR) from the hands of a shooter. In an ideal shooting case, the gunshot particles do not persist for more than 2 h in the hands of the shooter, provided that the hands have not been washed. However, for forensic analysis and inference, the extended persistence of GSR would be desirable. This study investigates a novel GSR sampling and detection protocol. Sampling was performed in the nostrils using swab devices impregnated in ethylenediaminetetraacetic acid (EDTA). The GSRs persisted for longer periods in nasal mucus than on the hands, and particles were detected 6 h after shooting occurred. The analytical determination was conducted by scanning laser ablation-inductively coupled plasma-mass spectrometry (SLA-ICPMS) which enable the identification of the number of particles and their elemental composition. Seventeen isotope signals corresponding to 13C, 205Tl and 15 analytes that are usually associated with the composition of GSR residues were monitored: 27Al, 29Si, 31P, 33S, 35Cl, 39K, 44Ca, 57Fe, 60Ni, 63Cu, 66Zn, 118Sn, 121Sb, 137Ba, and 208Pb. The SLA technique enabled the reduction of the swab analysis time to 40 min. The effectiveness of this methodology was evaluated with two types of firearms: a pistol and a shotgun. The results indicated that the methodology proposed for the analysis of the nasal GSR was effective and that it can improve or complement the forensic analyses and inferences presented in a court.  相似文献
