Validar a guerra: a construção do regime de Expertise estratégica

This article is intended to contribute to the interpretative analysis of war. For that purpose, it investigates how some apparatuses located in strategic thinking help to make modern war a social practice considered both technically feasible and, at the same time, legitimate for soldiers. In so doing, it makes use of two different but closely related theoretical fields, pragmatic sociology (finding inspiration in the work of scholars such as Luc Boltanski, Nicolas Dodier and Francis Chateauraynaud), and the sociology of scientific knowledge (based mostly on the work of Bruno Latour). On the one hand, the sociology of scientific knowledge has developed a productive questioning of the construction of scientific facts that is particularly relevant to the present research. On the other hand, pragmatic sociology generates a compatible framework able to describe collective actions. The combination of both approaches allows the description of the formation of a strategic expertise regime that supports the technical legitimacy of the use of military force. Together, the sociology of scientific knowledge and pragmatic sociology bring a particularly relevant perspective to research pertaining to war.info:eu-repo/semantics/publishe

Nalmefene reduces reward anticipation in alcohol dependence: an experimental functional magnetic resonance imaging study

Background Nalmefene (Selincro®) is a µ- and δ- opioid receptor antagonist, κ-opioid receptor partial agonist that has recently been approved in Europe for treating alcohol dependence. It offers a treatment approach for alcohol dependent individuals with “high risk drinking levels” to reduce their alcohol consumption. However, the neurobiological mechanism underpinning its effects on alcohol consumption remains to be determined. Using a randomised, double blind, placebo controlled within subject cross-over design we aimed to determine the effect of a single dose of nalmefene on striatal BOLD (blood oxygen level dependent) signal change during anticipation of monetary reward using the Monetary Incentive Delay Task following alcohol challenge. Methods and Materials 22 currently heavy drinking, non-treatment seeking alcohol dependent males were recruited. The effect of single dose nalmefene (18mg; Selincro®) on changes in a priori defined striatal region of interest (ROI) BOLD signal change during reward anticipation compared with placebo were investigated using functional MRI (magnetic resonance imaging). Both conditions were performed under intravenous alcohol administration (6% v/v infusion to achieve a target level of 80mg%). Results Datasets from 18 participants were available and showed that in the presence of the alcohol infusion, nalmefene significantly reduced the BOLD response in the striatal ROI compared with placebo. Nalmefene did not alter brain perfusion. Discussion Nalmefene blunts BOLD response in the mesolimbic system during anticipation of monetary reward and an alcohol infusion. This is consistent with nalmefene’s actions on opiate receptors, which modulate the mesolimbic dopaminergic system, and provides a neurobiological basis for its efficacy

Fortifications and the European military balance before 1914

This article analyses the evolution of permanent fortifications in Europe between 1870 and 1914. Despite the introduction in the 1880s of high explosive shells, intensive construction continued until the eve of war. Fortifications figured prominently in armaments budgets and in offensive as well as defensive strategic planning, while their design changed radically. Nonetheless, the pattern of development worked against the Central Powers. Austria-Hungary concentrated against Italy at the expense of the Balkans and Galicia; Germany concentrated on Alsace-Lorraine, neglecting the east until 1912. Whereas France modernised its eastern fortresses, Belgium did little, enticing Germany into the envelopment strategy that would draw Britain into the First World War
