Rapid Identification of Synthetic Cannabinoids in Herbal Incenses with DART‐MS and NMR

The usage of herbal incenses containing synthetic cannabinoids has caused an increase in medical incidents and triggered legislations to ban these products throughout the world. Law enforcement agencies are experiencing sample backlogs due to the variety of the products and the addition of new and still‐legal compounds. In our study, proton nuclear magnetic resonance (NMR) spectroscopy was employed to promptly screen the synthetic cannabinoids after their rapid, direct detection on the herbs and in the powders by direct analysis in real time mass spectrometry (DART‐MS). A simple sample preparation protocol was employed on 50 mg of herbal sample matrices for quick NMR detection. Ten synthetic cannabinoids were discovered in fifteen herbal incenses. The combined DART‐MS and NMR methods can be used to quickly screen synthetic cannabinoids in powder and herbal samples, serving as a complementary approach to conventional GC‐MS or LC‐MS methods.     

Public assistance of police during criminal investigations: Russian experience

This study examines the high levels of public unwillingness to assist police in criminal investigations in Russia. Variables of public trust of police, fear of crime, victimization, and prior contact with police are used to explain this phenomenon. Also included in the study are variables of police fear and avoidance of police. The findings suggest that higher levels of distrust in, as well as fear and avoidance of police are strong predictors of citizens’ unwillingness to assist police in Russia. The paper discusses potential implications of these findings for the 2011 police reform in Russia.     

China in Pacific Regional Politics

Abstract

Foreign aid from China to the island countries of the Pacific has grown rapidly over the last few decades and an expanding body of literature has examined various aspects of what this means for politics in the region generally. This article focuses on China’s impact on Pacific regional politics partly from the perspective of identity politics. It suggests that China has substantially increased its engagement with the Pacific island states by making use of its own identity as a South–South development partner in contrast to traditional (mainly Western) donors in the region. Unlike most traditional donors, however, China’s diplomacy and engagement are based largely on bilateralism, and this is likely to continue for the foreseeable future. This approach could continue to limit its impact on Pacific regionalism, regardless of how it projects its image.     

Economic,trade and development relations between South Africa and the European Union: The end of a strategic partnership? A South African perspective

ABSTRACT

The relationship between democratic South Africa and the European Union (EU) has been in existence for over 20 years, with its roots tracing back to anti-apartheid support measures. In its earlier form, it was anchored in the Reconstruction and Development Programme. Currently, it is guided by the National Development Plan of the National Planning Commission. This relationship has been tested over time, especially as a result of negotiations over the Economic Partnership Agreement with the EU. In the meantime, the euphoria that marked new South Africa's participation in the global system, with trade and development cooperation with the EU as one of the cornerstones, has waned considerably. The cancellation of several bilateral investment treaties with EU member states has further strained the relationship. While there are notable successes in the EU–South Africa Strategic Partnership, these may not be reflective of the actual strategic value of the partnership in the context of global shifts and the rising influence of emerging powers with which South Africa is integrating.

The Future of Northern Ireland: the Role of the Belfast/Good Friday Agreement Institutions

Since the 2016 Brexit referendum a series of crises has gripped Northern Ireland's politics. This has had a destabilising effect across society, which has arguably been felt most acutely by political unionism. The Belfast/Good Friday Agreement (B/GFA) of 1998 created a series of institutions to deal with political conflict in Northern Ireland, manage cross-border cooperation and normalise relations between the UK and Ireland. However, many aspects of it have been sparingly and ineffectually deployed, most notably the second and third strands dealing with north/south and east/west relations respectively. In this article, the authors argue that regular use of the institutional arrangements created by the Agreement would help to deal with the challenges currently facing Northern Ireland and help address unionist anxieties over the Protocol. Use of the North-South Ministerial Council (NSMC), the British Irish Council (BIC) and the British-Irish Intergovernmental Conference (BIIGC) should be prioritised. The unresolved issues arising from Brexit require a recommitment to the intergovernmental logic at the heart of the 1998 Agreement, despite the obstacles.

Sympathy for the devil: state engagement with criminal organisations in furtherance of public policy

Governments have long relied on non-state actors to assist in the implementation of public policy. Legitimate elements of civil society have become familiar instruments of governance. States have also engaged criminal actors to this end. This article will note examples of state collaboration with criminal interests, from pirates turned privateers during the 17th and 18th centuries, to the patriotic hackers of today. It will discuss the strategic considerations giving rise to such engagements, the pitfalls that may beset them, and the ethical considerations that might inform the decision by a state to enlist the services of illicit organisations.     

Secondary transfer of organic gunshot residues: Empirical data to assist the evaluation of three scenarios

The present study aimed at providing data to assess the secondary transfer of organic gunshot residues (OGSR). Three scenarios were evaluated in controlled conditions, namely displacing a firearm from point A to point B, a simple handshake and an arrest involving handcuffing on the ground. Specimens were collected from the firearm, the hands of the shooter and the non-shooter undergoing the secondary transfer in order to compare the amounts detected.Secondary transfer was observed for the three scenarios, but to a different extent. It was found that displacing a firearm resulted in secondary transfer in <50% of the experiments. The firearm also had an influence, as contrary to the pistol, no secondary OGSR were detected using the revolver. Shaking the hand of the shooter also transferred OGSR to the non-shooter's hand. In that case, the amount of OGSR was generally higher on the shooter than on the non-shooter. Finally, the largest secondary transfer was observed after the arrest with handcuffing with positive results in all cases using the pistol. In that scenario, the amounts on the shooter and the non-shooter were in the same range.This study highlights that the secondary transfer must be taken into account in the interpretation of OGSR. Indeed, an individual's hands might be contaminated by handling a firearm or having physical contact with a shooter.     

Quantitative Determination of Cannabinoids in Cannabis and Cannabis Products Using Ultra‐High‐Performance Supercritical Fluid Chromatography and Diode Array/Mass Spectrometric Detection

Ultra‐high‐performance supercritical fluid chromatography (UHPSFC ) is an efficient analytical technique and has not been fully employed for the analysis of cannabis. Here, a novel method was developed for the analysis of 30 cannabis plant extracts and preparations using UHPSFC /PDA ‐MS . Nine of the most abundant cannabinoids, viz . CBD , ?⁸‐THC , THCV , ?⁹‐THC , CBN , CBG , THCA ‐A, CBDA , and CBGA , were quantitatively determined (RSD s < 6.9%). Unlike GC methods, no derivatization or decarboxylation was required prior to UHPSFC analysis. The UHPSFC chromatographic separation of cannabinoids displayed an inverse elution order compared to UHPLC . Combining with PDA ‐MS , this orthogonality is valuable for discrimination of cannabinoids in complex matrices. The developed method was validated, and the quantification results were compared with a standard UHPLC method. The RSD s of these two methods were within ±13.0%. Finally, chemometric analysis including principal component analysis (PCA ) and partial least squares‐discriminant analysis (PLS ‐DA ) were used to differentiate between cannabis samples.
