La guerre vue d'Ochollo (Éthiopie méridionale)

La quête pour la reconnaissance de la subjectivité et la dignité est au coeur des mouvements sociaux actuels. Les Africains se battent pour obtenir la reconnaissance depuis l’époque où la traite des esclaves et plus tard la colonisation les ont dépouillés de leurs qualités humaines. Ces combats ont été essentiellement révélés par l’écriture et le monothéisme. L’article actuel suggère aux lecteurs de considérer la construction performative du moi où la subjectivité Africaine / Noire est représentée dans toute son autonomie. L’exemple empirique proposé est celui de l’Afrique centrale.     

Determination of bromazepam, clonazepam and metabolites after a single intake in urine and hair by LC-MS/MS. Application to forensic cases of drug facilitated crimes

The number of reports on drug facilitated crimes is increasing these last years. Apart from ethanol and cannabis, benzodiazepines (BZD) and analogs are the most common drugs reported to be used probably due to their amnesic and sedative properties. We have developed a rapid and sensitive method using LC-MS/MS triple stage quadrupole (TSQ) for the determination of single exposure to bromazepam (Lexomil, 6 mg) and clonazepam (Rivotril, 2 mg) in urine and hair of healthy volunteers. Chromatography was carried out on a Uptisphere ODB 5 microm, 2.1 mm x 150 mm column (Interchim) with a gradient of acetonitrile and formate 2 mM buffer, pH 3. Urine was extracted with Toxitube A (Varian) and allowed the detection of bromazepam, 3-hydroxy-bromazepam, clonazepam and 7-Aminoclonazepam for more than 6 days. Head hair, collected 1 month after the exposure, was treated by incubation with Soerensen buffer pH 7.6, followed by liquid-liquid extraction with dichloromethane for common BZD. A specific pre-treatment for amino-BZD, with an incubation of 15 min at 95 degrees C in 0.1 N NaOH before liquid-liquid extraction with dichloromethane, gave better recoveries and repeatability. After single exposure, bromazepam was present in powdered hair at 28 pg/mg and 7-Aminoclonazepam at 22 pg/mg in the first 1-cm segment, while no clonazepam was detectable. This method was applied in two forensic cases. It allowed us to determine bromazepam in urine 3 days after the alleged offense and in cut head hair at a concentration of 6.7 pg/mg only in the 2-cm proximal segment. The other case showed the presence of clonazepam and 7-Aminoclonazepam in urine a few hours after the offense and the presence of 7-Aminoclonazepam at about 3.2 pg/mg in axillary hair 4 months later.     

Testing for zopiclone in hair application to drug-facilitated crimes

The use of a drug to modify a person's behaviour for criminal gain is not a recent phenomenon. However, the recent increase in reports of drug-facilitated crimes (sexual assault, robbery) has caused alarm in the general public. The drugs involved can be difficult to detect due to low dosages or chemical instability. They possess amnesic properties and can be quickly cleared from the body fluids. In these situations, blood or even urine can be of poor interest. This is the reason why this laboratory developed an original approach based on hair testing by LC-MS/MS. Zopiclone (Imovane), due to its short half-life associated with rapid hypnotic activity, is considered as a compound of choice to sedate victims. To document the detection of zopiclone in hair, we first tested specimens obtained from two volunteers who had ingested a single 7.5 mg Imovane tablet, and from repetitive consumers of zopiclone. After pH 8.4 buffer incubation and extraction with methylene chloride/diethyl ether (80/20 (v/v)), hair extracts were separated on a Xterra MS C18 column using a gradient of acetonitrile and formate buffer. Zopiclone and diazepam-d5, used as internal standard, were detected by tandem mass spectrometry. A single exposure to zopiclone was detectable in the first hair segment of two volunteers at concentration of 5.4 and 9.0 pg/mg, respectively. Hair from repetitive consumers tested positive for zopiclone at concentrations of 37 and 66 pg/mg. Hair analysis was applied to two authentic criminal cases. In the first one, zopiclone tested positive in the corresponding hair segment at 4.2 pg/mg, in accordance with a single exposure to the drug. In the other expertise, zopiclone was detected in the two segments analyzed, at 21.3 and 21.5 pg/mg, making unlikely the hypothetical single exposure to zopiclone.     

Public expenditures in Canadian provinces: An empirical study of politico-economic interactions

It is widely believed that government ideology and electoral constraints are two major factors that influence the level of public expenditures. However, Frey and Schneider argue that the effects of the two phenomena are not simultaneous. Only when a government is popular can it pursue ideological goals, and when popularity is low, energies must be redirected toward gaining support from voters to win the next election. Data draw from the Canadian provincial case are used to test empirically this hypothesis. The findings support the Frey and Schneider explanation.     

The boundaries of acceptability: France’s positioning and rhetorical strategies during the Arab uprisings

Why did French leaders adopt vastly different positions during the Arab uprisings? Building on recent studies that emphasize the importance of rhetoric to understand states’ behaviour, this article argues that France’s inconsistent positioning results from decision-makers trying to remain within political boundaries that are acceptable both to their domestic audiences and to foreign partners. Through a chronological content analysis of France’s top decision-makers’ responses to the crises in Tunisia, Egypt, Libya and Bahrain, the article provides evidence that acceptability-enhancing rhetorical strategies contribute to explaining foreign policy positioning.     

Who gains from contract farming? Dependencies,power relations,and institutional change

ABSTRACT

The paper highlights the mechanisms through which outgrower contract farming creates dependencies at the local level. Using sugarcane case study in Malawi, we show that dependencies are created through redefinition of use rights to customary land and through the redefinition of cash flows into outgrower communities. Through this two-dimensional process, corporations can secure access to land, exert control over local communities and transform the local social relations of reciprocity serving as the pillars of resistance. Our results indicate that contract farming changes rural agrarian relations, transforms local family institutions by carefully selecting a few household members with influence into the scheme and selectively dispossessing the poor community members.     

From Victimization to Criminalization: General Strain Theory and the Relationship Between Poly-victimization and Delinquency

Although it is well established that victimization and delinquency are related, it is not clear how this relationship works, and victims and offenders are still often studied and treated as two distinct groups. General strain theory views victimization as a form of injustice, which can give rise to anger and eventually lead to delinquency. The authors examine victimization, in particular polyvictimization, as a criminogenic factor. Based on a sample of 1,400 youths 12–17 years old in Quebec (Canada), they examine polyvictimization in relation to delinquency as well as negative emotions that can result from victimization namely anger, depression, and posttraumatic stress. The findings show support for general strain theory and highlight the importance of anger for the relationship between victimization and juvenile delinquency.     

Religious revival,nationalism and the ‘invention of tradition’: political Tengrism in Central Asia and Tatarstan

This article aims to analyse the birth of a new ideological movement called ‘Tengrism’. According to its theoreticians, Tengrism represents a key element in the identity renewal of Turkic–Mongol peoples and should be adopted as the official religion by the new states of the region. This paper enquires into the ways in which Tengrism is being politically deployed in the service of post-Soviet nationalisms in Kyrgyzstan and Tatarstan and to a lesser extent, in Kazakhstan, Bashkortostan and Buryatia. Although the ideologues of Tengrism may be marginal to the political mainstream, it is nonetheless important to analyse the role of ‘ethnicized’ forms of religious expression and their relationship with the search for post-Soviet national identities.
