Simultaneous Identification of Four “Legal High” Plant Species in a Multiplex PCR High‐Resolution Melt Assay,

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.     

Robotic method for the analysis of morphine and codeine in urine.

A totally automated procedure has been developed for the detection and quantitation of morphine and codeine in urine case samples. The samples were initially screened for these drugs by a Syva EMIT Toxicology System (ETS). A Zymate laboratory robotic system confirms positive samples from Syva ETS by performing the hydrolysis, extraction, and derivatization of morphine and codeine. The derivatized morphine and codeine were detected using gas chromatography/mass spectrometry (GC/MS). Enzymatic hydrolysis conditions were experimentally optimized during method development. The automation of these procedures has proven to be reliable and efficient.     

Governance through global networks and corporate signaling

This article exposes a new form of global governance based on an emergent network of corporate social responsibility (CSR) schemes. Our study is the first to uncover the network structure of this system, based on a dataset that includes 61 transnational CSR schemes and 31,987 firms. We demonstrate that the network exhibits a significant level of cohesiveness, despite having evolved without any form of hierarchical control. Drawing on a social network analysis, we find a positive correlation among the sustainability performance of the firms, their membership in CSR schemes, and their network characteristics. We show that membership in multiple schemes and the firms’ position in the CSR‐schemes network constitute credible predictors of their sustainability performance, generating a separating equilibrium that distinguishes high from low CSR performers. We develop a model that explains the effectiveness of the CSR‐schemes network based on the synergistic properties of the network and on a distinctive signaling dynamic. Our findings highlight the potential contribution of CSR to the resolution of global governance dilemmas.     

A Clinical Study of Competency to Consent to Hospitalization and Treatment in Geriatric Inpatients*

Abstract: This study used a Competency Questionnaire modified for medical surgical patients (CQ‐Med). Twenty‐nine patients (ages 65–94 years) admitted to a geriatric medicine unit were studied. Along with the CQ‐Med, patients were administered several WAIS‐R subtests, the Blessed Dementia Scale (BDS), and Mini Mental State Exam (MMSE). Additionally, a blind forensic evaluation for competency to consent to hospitalization and treatment was performed for the purpose of validation of the CQ‐Med. Results of the study found that, as expected, increased age was correlated with decreasing performance on the CQ‐Med and decreased findings of competence by clinical exam. However, there was great variability within each age group, demonstrating individual differences in the progress of declining competency. CQ‐Med scores also correlated well with the WAIS‐R subtest raw and scaled scores. Scores on the MMSE and BDS were less well correlated. The CQ‐Med may be a useful adjunct in assessing declining competency in geriatric patients.     

How Law Changes the Environmental Mind: An Experimental Study of the Effect of Legal Norms on Moral Perceptions and Civic Enforcement

This paper examines how different legal instruments affect people's moral intuitions and willingness to engage in social enforcement in the field of environmental law. These instruments vary in terms of their governance technique, the process through which they were enacted, and their allocation of enforcement responsibilities. Their effect on citizens' moral evaluation and emotional reaction to corporate polluting behaviour are examined, based on an experimental survey of a representative sample of 1400 individuals in Israel.
Our findings demonstrate that their design influences people's level of moral and emotional resentment when faced by environmentally problematic behaviour, as well as their motivation to engage in private enforcement. The design of the regulatory instrument could thus generate biases in social reactions to polluting behaviour, irrespective of its actual ecological adverse effect. We analyse the moral and psychological mechanisms which underlie these effects and explore their various policy implications.     

A comparison of Latino and White citizen satisfaction with police

Latinos represent the fastest growing racial/ethnic population in the United States, yet paradoxically, are one of the least studied groups in the field of criminal justice (Schuck, Lersch, & Verrill, 2004). This study aimed to fill this gap by comparing citizen satisfaction with police among Latinos and Whites in the majority-minority city of San Antonio, Texas. Drawing upon prior research as a guide, the study modeled citizen satisfaction with police from a sample of 592 survey respondents that were contacted by telephone in the fall of 2005. Models across the two groups indicated that neighborhood disorder strongly influenced satisfaction and Latinos had slightly higher satisfaction levels when compared with Whites. Implications for future research are discussed regarding the enhancement of knowledge about ethnic differences in perceptions of police and the larger criminal justice system.     

Do Employers Prefer Workers Who Attend For‐Profit Colleges? Evidence from a Field Experiment

This paper reports results from a resume‐based field experiment designed to examine employer preferences for job applicants who attended for‐profit colleges. For‐profit colleges have seen sharp increases in enrollment in recent years despite alternatives, such as public community colleges, being much cheaper. We sent almost 9,000 fictitious resumes of young job applicants who recently completed their schooling to online job postings in six occupational categories and tracked employer callback rates. We find no evidence that employers prefer applicants with resumes listing a for‐profit college relative to those whose resumes list either a community college or no college at all.
