Disadvantageous decision-making as a predictor of drop-out among cocaine-dependent individuals in long-term residential treatment

Background: The treatment of cocaine-dependent individuals (CDI) is substantially challenged by high drop-out rates, raising questions regarding contributing factors. Recently, a number of studies have highlighted the potential of greater focus on the clinical significance of neurocognitive impairments in treatment-seeking cocaine users. In the present study, we hypothesized that disadvantageous decision-making would be one such factor placing CDI at greater risk for treatment drop-out. Methods: In order to explore this hypothesis, the present study contrasted baseline performance (at treatment onset) on two validated tasks of decision-making, the Iowa Gambling Task (IGT) and the Cambridge GambleTask (CGT) in CDI who completed treatment in a residentialTherapeutic Community (TC) (N D66) and those who dropped out ofTC prematurely (N D84). Results: Compared to treatment completers, CDI who dropped out of TC prematurely did not establish a consistent and advantageous response pattern as the IGT progressed and exhibited a poorer ability to choose the most likely outcome on the CGT. There were no group differences in betting behavior. Conclusion: Our findings suggest that neurocognitive rehabilitation of disadvantageous decision-making may have clinical benefits in CDI admitted to long-term residential treatment programs

Neuroscience-informed classification of prevention interventions in substance use disorders : an RDoC-based approach

Neuroscience has contributed to uncover the mechanisms underpinning substance use disorders (SUD). The next frontier is to leverage these mechanisms as active targets to create more effective interventions for SUD treatment and prevention. Recent large-scale cohort studies from early childhood are generating multiple levels of neuroscience-based information with the potential to inform the development and refinement of future preventive strategies. However, there are still no available well-recognized frameworks to guide the integration of these multi-level datasets into prevention interventions. The Research Domain Criteria (RDoC) provides a neuroscience-based multi-system framework that is well suited to facilitate translation of neurobiological mechanisms into behavioral domains amenable to preventative interventions. We propose a novel RDoC-based framework for prevention science and adapted the framework for the existing preventive interventions. From a systematic review of randomized controlled trials using a person-centered drug/alcohol preventive approach for adolescents, we identified 22 unique preventive interventions. By teasing apart these 22 interventions into the RDoC domains, we proposed distinct neurocognitive trajectories which have been recognized as precursors or risk factors for SUDs, to be targeted, engaged and modified for effective addiction prevention.Peer reviewe

Impulsivity as a vulnerability factor for poor addiction treatment outcomes: A review of neurocognitive findings among individuals with substance use disorders

The support of the Special Research Fund of Ghent University (Belgium) is gratefully acknowledged.With the current review, we explore the hypothesis that individual differences in neurocognitive aspects of impulsivity (i.e., cognitive and motor disinhibition, delay discounting and impulsive decision-making) among individuals with a substance use disorder are linked to unfavorable addiction treatment outcomes, including high drop-out rates and difficulties in achieving and maintaining abstinence. A systematic review of the literature was carried out using PubMed, PsycINFO and Web of Knowledge searches. Twenty-five unique empirical papers were identified and findings were considered in relation to the different impulsivity dimensions. Although conceptual/methodological heterogeneity and lack of replication are key limitations of studies in this area, findings speak for a prominent role of cognitive disinhibition, delay discounting and impulsive decision-making in the ability to successfully achieve and maintain abstinence during and following addiction treatment. In contrast, indices of motor disinhibition appear to be unrelated to abstinence levels. Whereas the relationship between impulsivity and treatment retention needs to be examined more extensively, preliminary evidence suggests that impulsive/risky decision-making is unrelated to premature treatment drop-out among individuals with a substance use disorder. The reviewed findings are discussed in terms of their clinical implications.Special Research Fund of Ghent University (Belgium

Long‐term variability and trends in meteorological droughts in Western Europe (1851–2018)

We analysed long‐term variability and trends in meteorological droughts across Western Europe using the Standardized Precipitation Index (SPI). Precipitation data from 199 stations spanning the period 1851–2018 were employed, following homogenisation, to derive SPI‐3 and SPI‐12 series for each station, together with indices on drought duration and severity. Results reveal a general absence of statistically significant long‐term trends in the study domain, with the exception of significant trends at some stations, generally covering short periods. The largest decreasing trends in SPI‐3 (i.e., increasing drought conditions) were found for summer in the British and Irish Isles. In general, drought episodes experienced in the last two or three decades have precedents during the last 170·years, emphasizing the importance of long records for assessing change. The main characteristic of drought variability in Western Europe is its strong spatial diversity, with regions exhibiting a homogeneous temporal evolution. Notably, the temporal variability of drought in Western Europe is more dominant than long‐term trends. This suggests that long‐term drought trends cannot be confirmed in Western Europe using precipitation records alone. This study provides a long‐term regional assessment of drought variability in Western Europe, which can contribute to better understanding of regional climate change during the past two centuries

Plantar povoações no território: (re)construindo a urbanização da capitania do Piauí, 1697-1761

The Piauí province´s urbanization has kept up with since late 17th century a complex process dealt among Portuguese Crown, the regal representatives, the network woven by the Casa da Torre and by the resident population in its countryside. What it was content of Rodelas countryside has begun to build with territorial identity since the foundation of first parish in 1697. Structuring itself discontinuously in time and space, the Piauí had reformed in 1758, year of creation of its autonomous government. And had became urban in 1761 when the king D. José I and marquis of Pombal had framed by the royal letter written in June 19 a territory formed by six towns and one city. Thus, this paper purposes to reconstructing the Piauí province according to agents involved in the urbanization processes. It proposes to deconstructing Crown´s polices by means towns strategically placed in territory aiming at control and "remedy" of routine injustices practiced in Piauí´s hinterlands. The method of presenting this reconstruction draws on interconnection between text (manuscript documents) and image (maps and photography) which in their discourses have represented a Piauí as space of experiences apprehended as much in official dimension as inhabitant´s everyday life.A urbanização da capitania do Piauí acompanhou, desde finais do século XVII, um complexo processo negociado entre a Coroa portuguesa, os representantes régios, a rede clientelar urdida pela Casa da Torre e a população residente em seus sertões. O que antes era conteúdo dos sertões de Rodelas passou a construir-se como identidade territorial a partir da fundação da primeira freguesia, em 1697, dedicada a Nossa Senhora da Vitória. Estruturando-se descontinuamente no tempo e no espaço, o Piauí reforma-se em 1758, ano da autonomização do seu governo. E fez-se urbano em 1761, quando D. José I e o marquês de Pombal equacionaram, por meio da carta régia de 19 de junho, um território formado por seis vilas e uma cidade. Nessa direção, o objetivo deste artigo consiste em reconstruir o processo de formação da capitania do Piauí segundo os agentes envolvidos na urbanização do território. Propõe-se descortinar as políticas da Coroa por meio da oficialização de povoações estrategicamente locadas no território visando o controle e o "remédio" das injustiças rotineiras do Piauí. O método de apresentar essa reconstrução vale-se da interconexão entre texto (documentação manuscrita) e imagem (mapas e fotografias), que em suas entrelinhas representam um Piauí como espaço de experiências sentidas tanto na dimensão oficial quanto no cotidiano dos seus moradores

Études culturelles: anthropologie culturelle et comparatisme : actes du XXXVe Congrès de la SFLGC

International audienceLes études culturelles n'ont pas bonne réputation en France. Au mieux, on les proclame étrangères à la tradition de la recherche universitaire française\,; au pire, on les accuse volontiers d'être un instrument du \guillemotleft politiquement correct \guillemotright américain, qui n'aurait d'autre ambition que de dénoncer l'exploitation ou l'oubli volontaire dont sont victimes les minorités (ethniques ou sexuelles). C'est réduire intentionnellement leur méthode et leurs ambitions, c'est ne vouloir voir que les postcolonial studies et les études féminines, mais c'est aussi négliger ce fait que l'évolution d'ensemble de la recherche en histoire au XXe\,s. a permis ce développement des études culturelles et, notamment, grâce à la mutation proposée par l'Ecole des Annales en France. Issues d'un colloque rassemblant les comparatistes français, les études proposées ici ont tenté de montrer la variété des territoires et les ambitions impliquées par les études culturelles. Ce panorama s'est voulu international aussi, sans pour autant succomber à l'autocélébration, comme le prouve une présentation du livre volontairement polémique - qui défend, mais aussi critique. Le débat est lancé, des itinéraires sont proposés : pourquoi ne pas les suivre sans préjugé

Délicieux supplices: érotisme et cruauté en occident

International audienceDu laboratoire sexuel de la Renaissance au libertinage des Lumières s'affirme en Occident l'exaltation de l'érotisme cruel. Des martyres soumises aux bourrelles sadiques, des dieux punis a la promotion de la fessée s'articule toute une grammaire discursive et visuelle de la douleur extatique. Malgré la crise de la société disciplinaire et patriarcale autour de la Première Guerre mondiale, la modernité hérite de sa fascination pour les supplices exquis. Accompagnant les différentes révolutions sexuelles qui se succèdent, des Années folles aux années 1960, l'obsession de l'érotisme cruel triomphe autant dans la culture des élites que dans les différents produits pop. La mutation de la sexualité postmoderne induit à son tour une progressive banalisation des délicieux supplices et l'on passe en quelques décennies de la période hot des sixties au SM chic et cool des petites annonces et des backrooms leather, à la fois si proches et si éloignés de la sacralité primitive d'un Nietzsche ou d'un Bataill
