Analysis of Δ-tetrahydrocannabinol in oral fluid samples using solid-phase extraction and high-performance liquid chromatography–electrospray ionization mass spectrometry

An analytical method using solid-phase extraction (SPE) and high-performance liquid chromatography–mass spectrometry (LC–MS) has been developed and validated for the confirmation of Δ⁹-tetrahydrocannabinol (THC) in oral fluid samples. Oral fluid was extracted using Bond Elut LRC-Certify solid-phase extraction columns (10 cm³, 300 mg) and elution performed with n-hexane/ethyl acetate. Quantitation made use of the selected ion-recording mode (SIR) using the most abundant characteristic ion [THC + H⁺], m/z 315.31 and the fragment ion, m/z 193.13 for confirmation, and m/z 318.00 for the protonated internal standard, [d₃-THC + H⁺]. The method proved to be precise for THC, in terms of both intra-day and inter-day analyses, with coefficients of variation less than 10%, and the calculated extraction efficiencies for THC ranged from 76 to 83%. Calibration standards spiked with THC between 2 and 100 ng/mL showed a linear relationship (r² = 0.999). The method presented was applied to the oral fluid samples taken from the volunteers during the largest music event in Portugal, named Rock in Rio-Lisboa. Oral fluid was collected from 40 persons by expectoration and with Salivette^®. In 55% of the samples obtained by expectorating, THC was detected with concentration ranges from 1033 to 6552 ng/mL and in 45% of cases THC was detected at concentrations between 51 and 937 ng/mL. However, using Salivette^® collection, 26 of the 40 cases had an undetectable THC.     

Transnational public goods provision: the increasing role of rising powers and the case of South Africa

The paper delineates three debates, which will be conflated. One line of discussion relates to public goods at a transnational level. Here, the referencing of debates regarding the characteristics of ‘a common good’ will be of significance. A second strand addresses the group of countries known as the ‘rising powers’ and the role these countries could play towards a globalised common good. A third discussion thread analyses South Africa as a case study for the main rising power on the African continent. By creating connections between the lines of discussion, this paper drives forward the debates on how the role of rising powers can be conceptually repositioned in the light of a changing global context, and explores how these countries can respond to global challenges.     

Behavioral Public Administration: Combining Insights from Public Administration and Psychology

Behavioral public administration is the analysis of public administration from the micro‐level perspective of individual behavior and attitudes by drawing on insights from psychology on the behavior of individuals and groups. The authors discuss how scholars in public administration currently draw on theories and methods from psychology and related fields and point to research in public administration that could benefit from further integration. An analysis of public administration topics through a psychological lens can be useful to confirm, add nuance to, or extend classical public administration theories. As such, behavioral public administration complements traditional public administration. Furthermore, it could be a two‐way street for psychologists who want to test the external validity of their theories in a political‐administrative setting. Finally, four principles are proposed to narrow the gap between public administration and psychology.     

Die elementaren (Fremd-)Erfahrungen der Gabe

What holds society together? In his famous essay The Gift (1925) Marcel Mauss answers this question. However, as this paper shows, he does so not by formulating something like a theory of reciprocity as was often assumed after Claude Lévi-Strauss’ brought forward his structuralist interpretation of Mauss. Instead, the reason why gift practices create obligatory, cohesive social bonds lies in experiences of ?being-possessed“ and self-transcendence. This assumption is proven by means of a new and detailed reading of Mauss’ Essai sur le don as well as by the anti-utilitarian reception of Mauss’ work by the Collège de Sociologie (Georges Bataille, Roger Caillois, Michel Leiris). Overall, Mauss’ theory of the gift features important elements of a theory of posession and self-transcendence which focuses on the dimensions of experience and action. This is why one can discern a certain similarity between Mauss’ and the pragmatist theory of action. Only against that backdrop the social binding force of gift practices can be explained.
