‘What Can You Say, Words It Is, Nothing Else Going’

This essay examines the capacity of language (‘word’) to convey what there is (‘world’). It draws on philosophical thought, which it seeks to apply to law while making specific reference to comparative legal studies, that is, to the investigation of law that is foreign to its interpreter.     

Le Raisonnement Juridique: Une Pratique Spécifique?

Selon une thèse largement partagée, le droit et une pratique sociale et les contributions des participants sont complémentaires les unes des autres. Dans ces conditions, le raisonnement juridique consiste d’abord en une interprétation de ces pratiques et présuppose un point de vue interne de la part de celui qui souhaite en rendre compte. Le raisonnement juridique est ainsi conçu comme une argumentation pratique, subordonnée aux exigences de la rationalité car ceux qui participent à la pratique juridique sont contraints de donner des raisons à leur action et ces raisons tissent un réseau de contraintes. Très séduisante, cette thèse qui doit beaucoup à la critique des réalistes par Hart, n’en demeure pas moins justiciable de quelque critique.     

The critique of language and its economy

Abstract

This paper draws upon and develops Paul Rabinow's concept of biosociality to analyse how the field of gambling research, the facts about gambling addiction and the politics of gambling regulation are in the process of transforming one another as the US gambling industry has begun to provide large amounts of funding for scientists and clinicians working on gambling problems. In particular, the paper focuses on the political economy of research that suggests that the negative consequences associated with gambling are not just social problems, but neurobiological ones. The paper introduces the notion of ‘biopolitical capital’ in order to describe how the gambling industry invests in particular kinds of research which are more likely to yield results that can be mobilized to support particular kinds of approaches to dealing with the social and personal problems associated with gambling.     

Sugar and fatty acid analysis in ecstasy tablets

Sugars and stearates (composed of fatty acids) are both frequent components used in the production of ecstasy tablets. Their analysis can therefore provide supplementary information useful for drug intelligence. Links established using these substances would be very significant as they should give us information about the manufacturer of the tablets. Two methods have been developed for the analysis of sugars and fatty acids by GC-MS and were applied to 109 ecstasy tablets. Characterisation of the samples should allow the differentiation of a certain number of them and furthermore their classification into groups. This is obtained by analysing the raw data using chemometric methods. Several pre-treatments have been tested together with six similarity measures on a small number of ecstasy samples in order to determine which combination would best characterise one ecstasy sample and differentiate it from the others at the same time. Normalisation followed by the fourth square and applied together with the squared cosine function appeared to give the best results and has been applied to all samples. The correlation values obtained of each sample with all others express the probability of a presence of a link between two samples. In order to verify the signification of these values, and thus of a link, all samples have been compared considering the data visually according to three selected criterions. The 109 examined samples could be divided into 67 groups, with 43 of them containing only one sample. Considering the distribution of their correlation values, sample pairs showing a value below 0.23 can be considered as linked. As the excipients are necessarily related to the blending, which also includes the active substance, and variation in the excipient content has been proven by the grouping of the samples, a low similarity value does indicate a link with regard to the producer. In conclusion, it appears that the result obtained with the excipients is certainly very valuable, but all other available information has to be taken into account as well before making any conclusions.     

Use of gold nanoparticles as molecular intermediates for the detection of fingermarks

Among the numerous methods dedicated to the detection of latent fingermarks, the MultiMetal Deposition (MMD) offers, as a main advantage, the ability to be applied on a great number of porous and non-porous surfaces, e.g., paper, plastic, glass, latex, and polystyrene, even if wetted. While considered as a powerful and sensitive technique, MMD is often neglected, mainly because of operational limitations (siliconized vessels, restrictive pH domain, numerous immersion baths, ...). In this contribution, we propose a modification of the standard MMD method so that the procedure is simplified with a number of baths reduced to a minimum. To reach this goal, it was necessary to obtain a fully operable solution which could detect fingermarks in a single step. We chose to take advantage of the molecular recognition mechanisms by functionalizing the gold nanoparticles with a molecular host able to bind itself to gold while keeping the ability to trap molecules in solution. Cyclodextrins were chosen as they can be easily chemically modified to offer gold-binding abilities. Moreover, they are widely used as hosts for various molecular guests (dyes, luminescent molecules, ...). This new formulation has been tested on three different surfaces to attest the feasibility of this strategy. Successful results were obtained with detailed fingermarks offering a good contrast to allow their identification without the need to enhance the results (such as with a physical developer). If the new formulation behaves very similarly to the old one, in terms of experimental conditions, it offers the additional advantage to develop fingermarks after immersing them in only one bath. The goal is thus reached.     

Drug intelligence based on MDMA tablets data: 2. Physical characteristics profiling

One of the tasks of the European project entitled “Collaborative Harmonisation of Methods for Profiling of Amphetamine Type Stimulants” (CHAMP) funded by the sixth framework programme of the European Commission was to develop a harmonised methodology for MDMA profiling and the creation of a common database in a drug intelligence perspective. Part I was dedicated to the analysis of organic impurities formed during synthesis in order to investigate traffic tendencies and highlight potential links between samples, whereas this part focuses on physical characteristics of the MDMA tablets. Diameter, thickness, weight and score were demonstrated to be reliable and relevant features in this drug intelligence perspective. Distributions of samples coming from the same post-tabletting batch (post-TB) and samples coming from different post-TB were very well discriminated by using the squared Euclidean or the Manhattan distance on standardised data. Our findings demonstrated the possibility to discriminate between MDMA samples issued from different post-TB and to find out links between samples coming from a same post-TB. Furthermore, the hypothesis that most of the MDMA samples found on the international market come from the same countries was supported.     

Let's stick together: Understanding Africa's secessionist deficit

Over the last 40 years, Africa has experienced relatively fewersecessionist conflicts than most other regions of the world,even though it is otherwise plagued with political violenceand its countries tend to display a higher prevalence of manyof the factors usually associated with separatism. After empiricallyestablishing Africa’s secessionist deficit, this articlereviews the few existing explanations for it before articulatinga theory which singles out the benefits to African regionalelites (and those who depend on them) of weak sovereign states.In Africa as elsewhere, the article argues, regional leaderscan be expected to capitalize on local grievances and promotesecessions if the potential rewards of a separatist state, inthe absence of international recognition, outweigh the potentialrewards associated with control or partial control of institutionsof the sovereign national state. What distinguishes Africanelites is the relatively greater material returns to sovereigntythat they face. Given the continent’s poverty, the undiversifiednature and commodity dependence of its economies, and the relativelack of accountability of state power, Africa offers a significantmaterial premium to internationally recognized sovereignty,tilting the odds for elites in favour of staying within thestate, even if they do not immediately benefit from power atthe centre. The article then tests the argument against actualAfrican cases of secession, showing that they are usually afunction of variations in the relative rewards of sovereignty.In conclusion, it argues that Africa’s weak sovereigntyequilibrium has contributed to its failure to develop.
