idPAD: Paper Analytical Device for Presumptive Identification of Illicit Drugs

As drug overdose deaths across the United States continue to rise, there is increasing interest in field testing of illicit substances. This work discusses a paper-based analytical device (idPAD) that can run a library of 12 colorimetric tests at the same time, each detecting different chemical functional groups and materials found in illicit drugs, distractor substances, and cutting agents. The idPAD requires no electricity, costs less than $2 USD, and requires minimal training to operate. The results of the 12 tests form a color barcode which is “read” by comparison to standard images. The accuracy of the idPAD was assessed using samples of heroin, cocaine HCl, crack, and methamphetamine at concentrations of 25%–100% in a lactose matrix, as well as pure lactose. Based on 840 “reads” by three different users, the idPAD showed 95% sensitivity and 100% specificity for detecting these drugs; the most common error was mistaking cocaine HCl for crack or crack for cocaine HCl. In a second step, samples of heroin, cocaine, and methamphetamine (n = 30) and distractor substances (pharmaceuticals, cutting agents, and other illicit drugs, n = 64) were tested by two readers, yielding a sensitivity of 100% and specificity of 97%. Targeted substances were detected reliably at 55–180 μg/lane, and the idPAD was found to be stable for at least 3 months when stored at room temperature. The library approach used in the idPAD may provide the accuracy and robustness necessary for a presumptive field drug test.     

The participatory turn in local policies: A product of the market

This article examines the relationship between local participatory policies and their market in France. The study stems from long‐term field research drawing on a variety of materials: qualitative interviews with citizen participation professionals (consultants or civil servants), questionnaires, and an analysis of public procurement. This study depicts the way both the industry and the policies of citizen participation are structured in France. It also explores how French participatory policies are coproduced through mechanisms of competition–collusion between clients (mainly local public authorities) and providers (consultants). Finally, the study questions the effects of this market on local policies, showing that the market cannot be interpreted as an unequivocal sign of a decline in actors along with political stakes in public policies.     

Does Context Matter in Determining Psychological Abuse? Effects of Pattern,Harm, Relationship,and Norms

This study explored contextual influences in determining whether psychologically aggressive actions constitute abuse. One hundred and thirty-one undergraduates completed measures of key experiences, attitudes, and traits, and rated abusiveness of behaviors in a series of vignettes. Vignettes varied contexts in which behaviors occurred, including whether the behavior was a pattern, whether there was harm to the recipient, characteristics of the initiator-recipient relationship, and whether behavior was normative. Results showed no effects for participants’ gender, past experiences with psychological aggression, and traits or attitudes. Findings indicated that behaviors were rated as more abusive when harm to the recipient was evident. Findings regarding patterns of behavior, relationship, and normative contexts were less consistent. Implications for measurement of psychological abuse are discussed.
