Identification of Eight Synthetic Cannabinoids,Including 5F‐AKB48 in Seized Herbal Products Using DART‐TOF‐MS and LC‐QTOF‐MS as Nontargeted Screening Methods

Synthetic cannabinoids are sprayed onto plant material and smoked for their marijuana‐like effects. Clandestine manufacturers modify synthetic cannabinoid structures by creating closely related analogs. Forensic laboratories are tasked with detection of these analog compounds, but targeted analytical methods are often thwarted by the structural modifications. Here, direct analysis in real time coupled to accurate mass time‐of‐flight mass spectrometry (DART‐TOF‐MS) in combination with liquid chromatography quadruple time‐of‐flight mass spectrometry (LC‐QTOF‐MS) are presented as a screening and nontargeted confirmation method, respectively. Methanol extracts of herbal material were run using both methods. Spectral data from four different herbal products were evaluated by comparing fragmentation pattern, accurate mass and retention time to available reference standards. JWH‐018, JWH‐019, AM2201, JWH‐122, 5F‐AKB48, AKB48‐N‐(4‐pentenyl) analog, UR144, and XLR11 were identified in the products. Results demonstrate that DART‐TOF‐MS affords a useful approach for rapid screening of herbal products for the presence and identification of synthetic cannabinoids.     

Brown Fades: The End of Court‐Ordered School Desegregation and the Resegregation of American Public Schools

In this paper, we investigate whether the school desegregation produced by court‐ordered desegregation plans persists when school districts are released from court oversight. Over 200 medium‐sized and large districts were released from desegregation court orders from 1991 to 2009. We find that racial school segregation in these districts increased gradually following release from court order, relative to the trends in segregation in districts remaining under court order. These increases are more pronounced in the South, in elementary grades, and in districts where prerelease school segregation levels were low. These results suggest that court‐ordered desegregation plans are effective in reducing racial school segregation, but that their effects fade over time in the absence of continued court oversight.     

DIRECTION OR CONCILIATION

The divorce custody reform and alternative dispute resolution movements have gained popularity with, and become intertwined by, legislators and adjudicators on both sides of the Atlantic Ocean. In this article, the theoretical strands of comparative divorce reform law and the Children Act 1989 are disentangled, and the threads of different factual situations—developed during 27 Preliminary Directions Hearings conducted in Englanďs Croydon County Court—are woven in. Hearings were initially meant simply to determine whether residence and access petitions could be resolved informally, without judicial intervention. The study, conducted shortly after the effective date of the legislation (October 14, 1991) quickly revealed distinct patterns in the proceedings. Faulty administration by the court resulted in chaos, undermining the efficacy of the program. Gender issues and power imbalances were often unintentionally amplified, rather than mitigated. Finally, the proceedings changed substantially during the 12-week period of study, resembling Hearing Directed Conciliation by the end.
